It is manifestly rotation invariant, and therefore mathematically much more transparent than Maxwell's original 20 equations in x,y,z components. The relativistic formulations are even more symmetric and manifestly Lorentz invariant. For the same equations expressed using tensor calculus or differential forms, see alternative formulations. The differential and integral formulations are mathematically equivalent and are both useful.

Following an improved and intense convective core structure with cooler cloud tops surrounding a large 38-nm wide eye. Dujuan started to undergo explosive intensification. On September 27, Dujuan rapidly reached peak intensity based on JTWC data, with winds of 240 km/h (150 mph). The typhoon became more symmetric, taking on annular characteristics, while featuring a large and well-defined eye.

On October 1, Chaba entered the Philippine area of responsibility, with PAGASA assigning the local name Igme, as it started to move in a northwestward direction. Several hours later, both agencies upgraded Chaba to a typhoon after its organization and structure had vastly improved. During the next day, Chaba became more symmetric as feeder bands wrapped into its deep central convection, signalling the onset of explosive intensification.

In academia, a related problem is collaborator discovery, where the goal is to suggest suitable collaborators to a researcher. While expertise finding is an asynchronous problem (employer looking for employee), collaborator discovery can be distinguished from expertise finding by helping establishing more symmetric relationships (collaborations). Also, while in expertise finding the task often can be clearly characterized, this is not the case in academic research, where future goals are more fuzzy.

This allows greater power, but are less efficient because not all of the light is correctly imaged into the rod, leading to increased thermal losses. These losses can be minimized by using a close-coupled cavity. This approach may allow more symmetric pumping, increasing beam quality, however. Another configuration uses a rod and a flashlamp in a cavity made of a diffuse reflecting material, such as spectralon or powdered barium sulfate.

Convection began to intensify and consolidate later that day; outflow had also improved, and became more symmetric in nature. Moving into warmer waters, Isaac continued to strengthen, and attained hurricane status on September 30. However, this period of intensification was short-lived, and the cyclone reached its peak intensity with winds of 85 mph (140 km/h) at around 0000 UTC on October 1. Around that time, a ragged eye feature appeared on satellite imagery.

Homonymous hemianopsia can be congenital, but is usually caused by brain injury such as from stroke, trauma, tumors, infection, or following surgery. Vascular and neoplastic (malignant or benign tumours) lesions from the optic tract, to visual cortex can cause a contralateral homonymous hemianopsia. Injury to the right side of the brain will affect the left visual fields of each eye. The more posterior the cerebral lesion, the more symmetric (congruous) the homonymous hemianopsia will be.

On November 25, a cold front was stalled over the western Atlantic Ocean. A day later, an extratropical storm producing hurricane-force winds developed about 200 mi (320 km) south-southeast of Cape Hatteras, North Carolina. The storm remained nearly stationary for several days near the coast, drifting westward and later to the south. On November 27, the storm's wind structure became more symmetric, with an inner core developing inside the larger extratropical low.

Transmission between two network nodes may be asymmetric, and the forward and reverse delays are not equal. Half the RTT value is the average of the forward and reverse delays and so may be sometimes used as an approximation to the end-to-end delay. The accuracy of such an estimate depends on the nature of delay distribution in both directions. As delays in both directions become more symmetric, the accuracy increases.

Their hearing evolved in response to bat predation, but the only clear example of reciprocal adaptation in bats is stealth echolocation. A more symmetric arms race may occur when the prey are dangerous, having spines, quills, toxins or venom that can harm the predator. The predator can respond with avoidance, which in turn drives the evolution of mimicry. Avoidance is not necessarily an evolutionary response as it is generally learned from bad experiences with prey.

On October 1, the system reversed its track, weakened slightly, and became more symmetric. By October 2, the strongest winds were located near the circulation center, based on nearby ship reports. Based on the observations, the Atlantic hurricane reanalysis project estimated that the system transitioned into a tropical storm on this day, although the storm could have been a subtropical cyclone. Around that time, maximum sustained winds were estimated at 60 mph (95 km/h).

Facial symmetry is also a valid marker of cognitive aging. Progressive changes occurring throughout life in the soft tissues of the face will cause more prominent facial asymmetry in older faces. Therefore, symmetrical transformation of older faces generally increases their attractiveness while symmetrical transformation in young adults and children will decrease their attractiveness. Males with more symmetric faces in old age have higher intelligence and are more efficient at information processing than males with less symmetric faces.

The eye feature became more pronounced throughout the day, with convection consolidating inward and becoming more symmetric. Accordingly, the FMS accordingly upgraded Pat to a Category 3 severe tropical cyclone by 18:00 UTC. The system became annular in nature on February 10, characterized by a lack of prominent banding features and uniform convection which surrounded its wide eye. Pat reached its peak intensity at 06:00 UTC that day as it began turning to the southwest.

Early on September 5, as the depression headed westward, the separation between the circulation center and the deep convection decreased. Several hours later, the depression intensified into Tropical Storm Henriette. The cyclone slowly became better organized on September 6, with the convective pattern becoming more symmetric, while the intensity increase to . Henriette turned to the northwest and accelerated somewhat as it began to feel the influence of Hurricane Gil, then located only about 285 mi (460 km) to the southwest.

An incidence structure is a triple () where is a set whose elements are called points, is a distinct set whose elements are called lines and is the incidence relation. The elements of are called flags. If () is in then one may say that point "lies on" line or that the line "passes through" point . A more "symmetric" terminology, to reflect the symmetric nature of this relation, is that " is incident with " or that " is incident with " and uses the notation synonymously with .

A weak area of low pressure developed over northwestern Cuba in association with a stationary front on January 6\. The frontal wave intensified as it moved into the central Atlantic, temporarily attaining hurricane-force winds by January 10\. Steered by anomalous high pressure, the disturbance turned southeast and tracked over warmer waters. Its associated fronts dissipated, its wind field became more symmetric, and convection increased near the center, leading to the formation of Subtropical Storm Alex by 18:00 UTC on January 12\.

The steric activity of the lone pair has long been assumed to be due to the orbital having some p character, i.e. the orbital is not spherically symmetric. More recent theoretical work shows that this is not always necessarily the case. For example, the litharge structure of PbO contrasts to the more symmetric and simpler rock salt structure of PbS and this has been explained in terms of PbII − anion interactions in PbO leading to an asymmetry in electron density.

Two parallel sets of en echelon veins in sandstone. The name has also been adopted by the birdwatching community to describe the familiar V-shaped formations of flights of geese, ducks and other migratory birds, though this more symmetric formation is more strictly defined as a V formation. In geology, en echelon describes an arrangement where a set of short linear features overlap or are staggered in a line that runs obliquely to the strike of the individual features. Echelon faults and en echelon veins are examples.

Such features might be reliable indicators of hidden fitness parameters such as a good immune system or developmental stability. It has been argued that more symmetric faces are preferred because symmetry might be a reliable sign of such hidden fitness parameters. However it is possible that high facial symmetry in an individual is not due to their superior genetics but due to a lack of exposure to stressors during development. It has been found that more symmetrical faces are rated as healthier than less symmetrical faces.

The central panel span was increased to 7.62 m (25 ft). The D-19's wing area was only slightly higher, with the result that the aspect ratio was increased from 15.4 to 19.4. The D-19 used a more symmetric Joukowsky profile in place of the strongly cambered Göttingen 535, so decreasing the pitching moment; over the outer panels the thickness/chord ratio reduced continuously from 15% to 8. There were also smaller refinements around the cockpit and pylon and a deeper, less rounded fuselage profile.

Similar to Tropical Storm Five, a new tropical cyclone that was not recognized in real time was found to have existed over the northern Atlantic. From October 16–17, a cold front moved eastward across the basin. An area of low pressure formed along the southern end of the dissipating boundary, initially harboring characteristics of an extratropical cyclone. This low became more symmetric while also intensifying, transitioning into a hurricane by 00:00 UTC on October 19 while located roughly 715 miles (1,150 km) southeast of Newfoundland.

Hurricane Leslie approaching the Iberian Peninsula on 13 October Later that day, Leslie began to intensify again, as satellite images showed that the storm developed a small central dense overcast with the cloud pattern became more symmetric. Meanwhile, Leslie turned to the south-southeast, as the storm was steered by a mid-level ridge. Over the next day, Leslie continued to intensify under favourable environment. Microwave data revealed that the storm developed a small mid-level eye, and Leslie re-attained hurricane status early on 10 October.

A low pressure area of non-tropical origins developed into Subtropical Storm Sean at 06:00 UTC on November 8 about southwest of Bermuda. While convection and the wind field had become more symmetric, the system remained a subtropical cyclone due to the associated upper-level low. Within 12 hours, Sean separated from the low and transitioned into a tropical cyclone, after developing a warm core. It developed outflow and intensified due to light wind shear, combined with sufficiently warm water temperatures of at least .

Teleportation can be applied not just to pure states, but also mixed states, that can be regarded as the state of a single subsystem of an entangled pair. The so-called entanglement swapping is a simple and illustrative example. If Alice has a particle which is entangled with a particle owned by Bob, and Bob teleports it to Carol, then afterwards, Alice's particle is entangled with Carol's. A more symmetric way to describe the situation is the following: Alice has one particle, Bob two, and Carol one.

Kiggins S., Uang C.-M. Reducing residual drift of buckling-restrained braced frames as a dual system (2006) Engineering Structures, 28 (11), pp. 1525–1532. A buckling-restrained brace (BRB) consists of a steel core surrounded by a hollow steel section, coated with a low-friction material, and then grouted with a specialized mortar. The encasing and mortar prohibit the steel core from buckling when in compression, while the coating prevents axial load from being transferred to the encasement, thus preventing strength loss and allowing for better and more symmetric cyclic performance.

Upon being named, Andres marked latest date that the first named storm of a season developed since 1969 when Tropical Storm Ava developed on July 1 of that year. By the morning of June 22, very deep thunderstorm activity existed near the center, and the overall convective pattern had become more symmetric in nature. Favorable conditions, warm sea surface temperatures, allowed Andres to gradually intensify as it tracked near the Mexican coastline. However, strong wind shear, a factor that generally weakens tropical cyclones, had little effect on the developing storm.

The wing had a thick and cambered profile inboard of the tips, which had a thinner and more symmetric profile. Initially the wing plan was rectangular, with triangular ailerons mounted on straight hinges which were attached to the front spar at the tips, reaching the trailing edge inboard. Later, the aileron area was reduced, partly by cropping them inboard and also by tapering their trailing edges and rounding their tips. Each wing was braced from the lower fuselage with an asymmetric, V-form, streamlined strut to the two spars at about one-third span.

The Karakán's wing had a greater span and area. Lippisch had a used standard Göttingen airfoil whereas Rotter used one of his own, though both designers chose to merge into more symmetric profiles outboard. The Karakán was the heavier of the two, with the higher wing loading. The major differences were in the forward part of the semi-monocoque, ply-covered fuselages; the Karakán replaced the open Wien cockpit with one enclosed under a removable, wood framed canopy, with four transparent panels on each side, which maintained the smoothly increasing fuselage section.

The storm began to intensify again around 06:00 UTC as it stalled off the coast of Mexico. Soon after, the cyclone began moving in a northerly direction. Over the next twelve hours, Carlotta experienced little change in organization before peaking at 00:00 UTC on June 17, with maximum sustained winds of 65 mph (100 km/h) and a minimum central pressure of 997 mbar (29.44 inHg) while located only 30 mi (50 km) south-southeast of Acapulco. Around that time, the NHC noted that the system's structure had improved significantly, with a contracting eye and more symmetric eyewall.

Raman spectra of the 2-norbornyl cation show a more symmetric species than would be expected for a pair of rapidly equilibrating classical ions. Since the proposed reaction rates for the classical ion rearrangements are slower than the Raman timescale, one would expect the Raman spectra to indicate a less symmetric species if the classical picture were correct. Some studies of the C NMR in particular favored interpretation via the protonated nortricyclene structure. In addition, Raman spectra of the 2-norbornyl cation in some acidic solvents show an absorption band at 3110 cm indicative of an electron-depleted cyclopropane ring.

The shear began to relax after that, allowing Paulette to become more organized and begin to form an eye. At 03:00 UTC on September 13, Paulette was upgraded to hurricane status. Dry air entrainment gave the storm a somewhat ragged appearance, but it continued to slowly strengthen as it approached Bermuda with its eye clearing out and its convection becoming more symmetric. Paulette then made a sharp turn to the north and made landfall in northeastern Bermuda at 09:00 UTC on September 14 with 90 mph (150 km/h) winds and a 973 mb (28.74 inHg) pressure.

Multi-spectral satellite imagery revealed that Mekunu had developed an eye as early as May 23, at which time the IMD upgraded it to a severe cyclonic storm. Benefiting from favorable environmental conditions, the cyclone became more symmetric, intensifying into a very severe cyclonic storm six hours later. The cyclone continued to track northwestward under the influence of a subtropical ridge. On May 25, it reached its peak intensity as an extremely severe cyclonic storm, with the JTWC estimating peak 1-minute sustained winds of 185 km/h (115 mph), equivalent to a Category 3 storm on the Saffir-Simpson scale.

Early aircraft designers appreciated that whilst low take-off speeds required wings with high lift, high camber sections, more symmetric, low camber sections produced less drag at speed. One solution was to make a wing sufficiently flexible chordwise that the section could be altered in flight. This was the approach taken by Adolphe Lachassagne; his AL 3 was the first French monoplane with such a wing. Details of the profile changing mechanism for the AL 3 are sparse, though each two spar wing was in two parts, a forward rigid metal structure and a rear flexible wooden structure.

The relative error in T is larger than might be reasonable so that the effect of the bias can be more clearly seen. In the figure the dots show the mean; the bias is evident, and it does not change with n. The variance, or width of the PDF, does become smaller with increasing n, and the PDF also becomes more symmetric. In Figure 7 are the PDFs for Method 1, and it is seen that the means converge toward the correct g value of 9.8 m/s2 as the number of measurements increases, and the variance also decreases.

In particular, its cloud pattern became much more symmetric, and some cloud tops cooled to -70 °C (-95 °F). Around the same time, Cristobal accelerated toward the northeast as it became embedded within the mid-latitude westerlies ahead of an advancing shortwave trough. An area of relatively warm cloud tops at the center of a central dense overcast gave way to an eye feature evident on visible satellite imagery on August 28. Rapidly gaining latitude, Cristobal reached its peak intensity at 18:00 UTC, with winds of 85 mph (140 km/h), roughly due south of Halifax, Nova Scotia.

There is an even more symmetric embedding of Möbius–Kantor graph in the double torus which is a regular map, with six octagonal faces, in which all 96 symmetries of the graph can be realized as symmetries of the embedding; credits this embedding to . Its 96-element symmetry group has a Cayley graph that can itself be embedded on the double torus, and was shown by to be the unique group with genus two. The Cayley graph on 96 vertices is a flag graph of the genus 2 regular map having Möbius–Kantor graph as a skeleton.

Rational Bézier curve - polynomial curve defined in homogeneous coordinates (blue) and its projection on plane - rational curve (red) In mathematics, homogeneous coordinates or projective coordinates, introduced by August Ferdinand Möbius in his 1827 work Der barycentrische CalculAugust Ferdinand Möbius: Der barycentrische Calcul, Verlag von Johann Ambrosius Barth, Leipzig, 1827., are a system of coordinates used in projective geometry, as Cartesian coordinates are used in Euclidean geometry. They have the advantage that the coordinates of points, including points at infinity, can be represented using finite coordinates. Formulas involving homogeneous coordinates are often simpler and more symmetric than their Cartesian counterparts.

Wind shear decreased further, and the storm's convection became more symmetric with an intermittent eye feature in the center. Based on the presence of the eye and estimates from satellite imagery, it is estimated that Gordon intensified into a hurricane early on September 13. Hurricane Gordon as seen from Space Shuttle Atlantis (STS-115) on September 17 After becoming a hurricane, Gordon underwent rapid deepening as the eye became better defined and more intense. In 24 hours, the winds increased by to a peak intensity of early on September 14, while located about southeast of Bermuda.

Therefore, the eye of the typhoon became cloud-filled, while the deepest convection around the core was also becoming warmer. The system began to track north-northwestward in the afternoon, when the cold dense overcast has decreased in size and become less symmetric. Severe Tropical Storm Genevieve on August 11 Genevieve reformed a eye with more symmetric and organized convection for short time early on August 10, but the eye disappeared very soon as the system elongated more. Upper-level analysis indicated a complex environment— an anticyclone located to the southeast, a TUTT cell to the west, and a second anticyclone to the north.

Intuitively, it consists of elementary particles or bound states that are sufficiently well separated that their interactions with each other are ignored. The idea is that whatever physical process one is trying to study may be modeled as a scattering process of these well separated bound states. This process is described by the full Hamiltonian , but once it's over, all of the new elementary particles and new bound states separate again and one finds a new noninteracting state called the out state. The S-matrix is more symmetric under relativity than the Hamiltonian, because it does not require a choice of time slices to define.

The hurricane continued westward or slightly north of due west. Late on August 10, deep convection significantly expanded and became more symmetric, while Dvorak intensity estimates indicated that Dora reached Category 4 intensity; the NHC upgraded the storm to a Category 4 hurricane accordingly. Hurricane Dora late on August 12 Later on August 11, the NHC predicted relatively slow weakening beginning in about 24 hours, as the storm would cross over slightly colder sea surface temperatures in the wake of Hurricane Eugene. However, at 00:00 UTC on August 12, Dora attained its peak intensity with maximum sustained winds of 140 mph (220 km/h) and a minimum barometric pressure of .

But they then reneged, modifying the theory to break its five-dimensional symmetry. Their reasoning, as suggested by Edward Witten, was that the more symmetric version of the theory predicted the existence of a new long range field, one that was both massless and scalar, which would have required a fundamental modification to Einstein's theory of general relativity. Minkowski space and Maxwell's equations in vacuum can be embedded in a five-dimensional Riemann curvature tensor. In 1993, the physicist Gerard 't Hooft put forward the holographic principle, which explains that the information about an extra dimension is visible as a curvature in a spacetime with one fewer dimension.

A symmetric core and extra feeder bands prompted the JTWC to upgrade it to a super typhoon. Later that day, satellite imagery showed that Atsani was more symmetric and deep with feeder bands wrapping tighter into an expanded 34 nautical-mile diameter eye. Therefore, the JTWC upgraded Atsani further to a Category 5 super typhoon and it attained its peak intensity of 1-minute sustained winds of 260 km/h (160 mph). Atsani moved in a northwestward direction as it was later downgraded to a Category 4 super typhoon intensity on August 20 and at typhoon category later that day as it weakened further.

Indirect recursion is also called mutual recursion, which is a more symmetric term, though this is simply a difference of emphasis, not a different notion. That is, if f calls g and then g calls f, which in turn calls g again, from the point of view of f alone, f is indirectly recursing, while from the point of view of g alone, it is indirectly recursing, while from the point of view of both, f and g are mutually recursing on each other. Similarly a set of three or more functions that call each other can be called a set of mutually recursive functions.

Cope estimated the size of the animal as that of an alligator; Charles Craig Mook later compared it to a wolf. The specimen represents a subadult individual, as can be seen from the suture between the vertebral centrum and the neural arch. In 1878 Cope named a second species: Tichosteus aequifacies.E.D. Cope, 1878, "Descriptions of new extinct Vertebrata from the Upper Tertiary and Dakota Formations", Bulletin of the United States Geological and Geographical Survey of the Territories, 4(2): 379-396 The specific name is derived from Latin aequus, "equal", and facies, "face", referring to the more symmetric extremities of the vertebrae as compared to T. lucasanus.

A weak steering regime directed the storm just east of Bermuda as it weakened to a tropical storm on July 13, and a large upper-level low over the central Atlantic steered it east and southeast. After generally maintaining its strength for several days, an eye redeveloped and convection became more symmetric about the feature on July 18, prompting the NHC to upgrade Bertha to a hurricane around 18:00 UTC that day. The storm rapidly accelerated ahead of a trough off the East Coast of the United States, forcing Bertha into rapidly cooler waters. Its wind field became extremely asymmetric and deep convection near the center dissipated, indicative of an extratropical transition that Bertha completed by 12:00 UTC on July 20\.

On 12 April, the previously detrimental wind shear began easing, allowing the structure to become more symmetric. On that day, an eye feature began developing in the center of Fantala, indicative of strengthening. At 12:00 UTC on 12 April, the MFR upgraded Fantala to severe tropical storm status, and six hours later, the JTWC upgraded it to the equivalent of a minimal hurricane, with 1 minute maximum sustained winds of 120 km/h (75 mph); rapid strengthening was prevented by the entrainment of nearby dry air, although the core of convection continued to contract. At 06:00 UTC on 13 April, the MFR upgraded Fantala to tropical cyclone status, with 10 minute winds of 130 km/h (80 mph).

5, 190 (2010)R.A. Zubarev, Role of stable isotopes in life – Testing isotopic resonance hypothesis, Genomics Proteomics Bioinformatics 9, 15 (2011) postulates that certain isotopic compositions of chemical elements affect kinetics of chemical reactions involving molecules built of these elements. The isotopic compositions for which this effect is predicted are called resonance isotopic compositions. Fundamentally, the IsoRes hypothesis relies on a postulate that less complex systems exhibit faster kinetics than equivalent but more complex systems. Furthermore, system’s complexity is affected by its symmetry (more symmetric systems are simpler), and symmetry (in general meaning) of reactants may be affected by their isotopic composition. The term “resonance” relates to the use of this term in nuclear physics, where peaks in the dependence of a reaction cross section upon energy are called “resonances”.

On July 15, the NHC noted that an area of low pressure was forecast to form well south of Mexico early the subsequent week. An area of disturbed weather became established south of the Gulf of Tehuantepec the following day, organizing sufficiently to be deemed a tropical depression by 21:00 UTC on July 21. Despite moderate northeasterly wind shear, the depression intensified into Tropical Storm Georgette by 15:00 UTC on July 22 and was further upgraded to a Category 1 hurricane by 03:00 UTC on July 24. Over a 24-hour period ending at 03:00 UTC July 25, the cyclone's maximum winds increased from 75 mph (120 km/h) to a peak of 130 mph (215 km/h) as convection became more symmetric and an eye cleared.

Despite decreasing ocean temperatures, Darby intensified further to attain winds of 105 mph (165 km/h). Strengthening was no longer expected as Darby moved over sea temperatures of less than 79°F (26°C), but on July 16, Darby managed to develop an annular structure. Convection became more symmetric, outer rainbands dissipated, and the 25 mile- wide (35 km) eye became increasingly well defined. Darby reached its peak intensity as a Category 3 hurricane with winds of 120 mph (195 km/h) and a minimum pressure of 958 mbar (hPa; 28.29 inHg). However, twelve hours later, Darby weakened back to a Category 2 hurricane as convection deteriorated. Embedded in cool sinking air and moving over decreasing sea surface temperatures, Darby began a gradual weakening trend, degrading to a Category 1 hurricane by July 18.

" Hurricane Epsilon shortly after peak intensity on December 5 As it continued eastward, Epsilon developed characteristics of an annular hurricane; such cyclones, more often found in the deep tropics with greater intensity, have circular eyes, surrounded by a nearly uniform ring of convection and a general lack of thunderstorms outside the ring. For several days, the intensity fluctuated in a narrow range, and although Epsilon was briefly downgraded to tropical storm status on December 4, the NHC assessed it as remaining a hurricane. After it was thought to have weakened, the eye became more symmetric as the ring of convection became stronger. The hurricane remained difficult to forecast, as NHC forecaster Lixion Avila remarked, "There are no clear reasons... and I am not going to make one up... to explain the recent strengthening of Epsilon.

A tropical wave and attendant region of convection developed into a tropical depression at 18:00 UTC on August 23 while located near Mayaguana in the Bahamas; twelve hours later, the depression intensified into Tropical Storm Cristobal. The newly formed cyclone turned northward following formation, directed toward a break in a subtropical ridge. Although located in an unfavorable environment, Cristobal steadily intensified and was upgraded to a Category 1 hurricane at 00:00 UTC on August 26 despite a partially exposed circulation and disorganized cloud pattern. As the hurricane turned east- northeastward the following day, its cloud pattern became much more symmetric and an eye became evident, yielding peak winds of 85 mph (140 km/h). Thereafter, a frontal boundary wrapped around the storm's circulation, transitioning the system into an extratropical cyclone by 12:00 UTC on August 29\.

As the storm continued to develop, the radius of maximum winds shrank, resulting in a smaller storm than the previous Cyclone Chapala. At 12:00 UTC on November 7, the JTWC upgraded Megh to the equivalent of a hurricane after a small defined eye became evident. The storm began rapid deepening that day due to the continued low shear and warm water temperatures, and the convection became more symmetric and circular. Such intensification was not anticipated by tropical cyclone forecast models, which emphasized that the external conditions, such as dry air from the west, would be unfavorable. At 06:00 UTC on November 7, the IMD upgraded Megh to a severe cyclonic storm, and just nine hours later upgraded it to a very severe cyclonic storm - the equivalent to hurricane intensity with 3 minute winds of 120 km/h (75 mph).

Concurrently, a warm-core seclusion at the upper-levels marked the transition to a more symmetric structure, although convective activity near the center remained sparse. Once separated from the jet stream, the cyclone turned sharply to the south-southeast in response to a mid- latitude trough over the central Atlantic, entering a region with warmer waters of above average for January. The system underwent substantial changes to its cyclonic structure on January 11–12: frontal boundaries separated from the core of the cyclone, its core became symmetric, it became co-located with an upper-level low, and intense albeit shallow convection developed atop the circulation. All these factors indicated the storm's transition into a subtropical cyclone by 18:00 UTC on January 12, at which point it was situated 1,150 mi (1,850 km) west-southwest of the Canary Islands and received the name Alex from the National Hurricane Center.

Compounding the effects of cooler water was an eyewall replacement cycle. This resulted in rapid weakening, with Blanca's winds falling to 90 mph (150 km/h) by 12:00 UTC on June 5. The previously small core of Blanca dramatically expanded to 65 mi (100 km) across, with convection asymmetrically wrapping around it. During this period, a mid-level ridge north of the hurricane moved east and allowed Blanca to acquire a steady northwest track. Re-intensification ensued on June 6 as the hurricane moved away from its cold wake and traversed an area of warmer water. Throughout June 6, Blanca's convective structure became more symmetric as it completed its eyewall replacement cycle. Aided by impressive outflow, the hurricane regained Category 4 status by 12:00 UTC, marking its secondary peak intensity with winds of 130 mph (215 km/h). Soon thereafter, Blanca moved back over cooler waters and began weakening.

The stone carving is apparently interpreted (read) from right to left, since the signs and other visual elements are to the right. The main sign represents a skull, possibly described as “anthropozoomorphic”. It depicts a de-fleshed jaw and an open eye, which departs from associations with other known mesoamerican deities.Schellhas’ God A or other Maya skeletal supernaturals The deity is perceived as such by the presence of ear decorations. It also a ‘bracket’ element in the upper head not unlike those of some Maya signs such as T1016 (God C’s head) and sign SNA.Macri and Looper 2003: 164 A ‘fire’ volute extends forward from the deity brow or nose. It can be compared with sign T122, although its shape is more symmetric. It could be said at this point that the motif of a ‘fire’ or ‘breath’-exhaling skull is not completely unknown within Maya iconography and writing.

As FA reflects developmental stability and quality, it has been suggested that we prefer those as more attractive/with low FA because it signals traits such as health and intelligence. Research has shown that the female partners of men with lower levels of FA experience a higher number of copulatory orgasms, compared to the female partners of males with higher levels of FA. Other studies have also found that the voices of men and women with low fluctuating asymmetry are rated as more attractive, suggesting that voice may be indicative of developmental stability. Research has shown attractiveness ratings of men's scent are negatively correlated with FA, but FA is unrelated to attractiveness ratings for women's scent, and women's preferences for the scent of more symmetric men appears limited to the most fertile phases of the menstrual cycle. However, research has failed to find changes in women's preferences for low FA across the menstrual cycle when assessing pictures of faces, as opposed to scents.

Its intensification continued to be slow due to the presence of some dry air and light northerly wind shear, but this eventually subsided, allowing Laura to become more organized and form a banding-type cloud-filled eye late on August 25. With no more negative factors hindering strengthening and sea surface temperatures around 30 °C, Laura began to rapidly intensify, becoming a Category 2 at 06:00 UTC on August 26 before achieving Category 3 status just six hours later, making it the first major hurricane of the season. By this time, Laura was beginning to make a gradual northward turn around the high-pressure ridge in front of a mid-to-upper-level trough over Texas and the Southern Great Plains. Laura rapidly strengthening before landfall, then rapidly weakening after landfall As the day progressed, Laura's eye continued to clear out and the deep convection around it intensified and became more symmetric.

"The Problem of Social Cost" (1960) by Ronald Coase, then a faculty member at the University of Virginia, is an article dealing with the economic problem of externalities. It draws from a number of English legal cases and statutes to illustrate Coase's belief that legal rules are only justified by reference to a cost–benefit analysis, and that nuisances that are often regarded as being the fault of one party are more symmetric conflicts between the interests of the two parties. If there are sufficiently low costs of doing a transaction, legal rules would be irrelevant to the maximization of production. Because in the real world there are costs of bargaining and information gathering, legal rules are justified to the extent of their ability to allocate rights to the most efficient right-bearer. Along with an earlier article, “The Nature of the Firm”, "The Problem of Social Cost" was cited by the Nobel committee when Coase was awarded the Nobel Memorial Prize in Economic Sciences in 1991.

As a result, the JTWC upgraded the storm to typhoon status at 06:00 UTC, followed by the JMA at 12:00 UTC. Nangka reached its first peak intensity at 12:00 UTC on July 7, when JMA estimated 10 minute sustained winds 185 km/h (115 mph). The typhoon was aided by excellent radial outflow enhanced by a TUTT cell to the northwest, and it developed a well- defined eye 48 km (30 mi) in diameter. Three simultaneously active typhoons on July 9: (from left to right) Linfa, Chan-hom and Nangka After reaching its initial peak intensity, Nangka slightly weakened as convection along the west side of the system was restricted due to the TUTT cell, and the eye became cloud-filled. Decreasing wind shear and increasing sea surface temperatures allowed the intensification trend to resume, and the structure became more symmetric late on July 8 as it moved toward the Northern Marianas Islands.

Shortly thereafter, the system began a period of rapid intensification that was described by NHC forecasters as "astounding" and "impressive". At 0000 UTC on October 21, Raymond was upgraded to a Category 1 hurricane; six hours later, it was upgraded to a Category 2 hurricane as a small yet well-defined eye became obvious on both visible and infrared satellite imagery. In conjunction with satellite intensity estimates, the hurricane was upgraded to a major hurricane—a Category 3 or higher on the Saffir-Simpson hurricane wind scale—making Raymond the first of the 2013 Pacific hurricane season and the first in the West Hemisphere during 2013. Slowing to a halt, the system temporarily ceased its intensification trend as it underwent an eyewall replacement cycle. By the afternoon hours of October 21, however, the system increased in organization, noted by a more symmetric and warm eye. At 1800 UTC, Raymond attained its peak intensity with maximum sustained winds of 125 mph (205 km/h) and a minimum barometric pressure of 951 mb (hPa; 28.08 inHg).

The Desargues configuration viewed as a pair of mutually inscribed pentagons: each pentagon vertex lies on the line through one of the sides of the other pentagon. The ten lines involved in Desargues's theorem (six sides of triangles, the three lines and , and the axis of perspectivity) and the ten points involved (the six vertices, the three points of intersection on the axis of perspectivity, and the center of perspectivity) are so arranged that each of the ten lines passes through three of the ten points, and each of the ten points lies on three of the ten lines. Those ten points and ten lines make up the Desargues configuration, an example of a projective configuration. Although Desargues's theorem chooses different roles for these ten lines and points, the Desargues configuration itself is more symmetric: any of the ten points may be chosen to be the center of perspectivity, and that choice determines which six points will be the vertices of triangles and which line will be the axis of perspectivity.

Although Desargues' theorem chooses different roles for its ten lines and points, the Desargues configuration itself is more symmetric: any of the ten points may be chosen to be the center of perspectivity, and that choice determines which six points will be the vertices of triangles and which line will be the axis of perspectivity. The Desargues configuration has a symmetry group S5 of order 120; that is, there are 120 different ways of permuting the points and lines of the configuration in a way that preserves its point-line incidences . The three-dimensional construction of the Desargues configuration makes these symmetries more readily apparent: if the configuration is generated from five planes in general position in three dimensions, then each of the 120 different permutations of these five planes corresponds to a symmetry of the configuration . The Desargues configuration is self-dual, meaning that it is possible to find a correspondence from points of one Desargues configuration to lines of a second configuration, and from lines of the first configuration to points of a second configuration, in such a way that all of the configuration's incidences are preserved .

The tangent at a point (a, b) of the curve is the line of equation (x-a)p'_x(a,b)+(y-b)p'_y(a,b)=0, like for every differentiable curve defined by an implicit equation. In the case of polynomials, another formula for the tangent has a simpler constant term and is more symmetric: :xp'_x(a,b)+yp'_y(a,b)+p'_\infty(a,b)=0, where p'_\infty(x,y)=P'_z(x,y,1) is the derivative at infinity. The equivalence of the two equations results from Euler's homogeneous function theorem applied to P. If p'_x(a,b)=p'_y(a,b)=0, the tangent is not defined and the point is a singular point. This extends immediately to the projective case: The equation of the tangent of at the point of projective coordinates (a:b:c) of the projective curve of equation P(x, y, z) = 0 is :xP'_x(a,b,c)+yP'_y(a,b,c)+zP'_z(a,b,c)=0, and the points of the curves that are singular are the points such that :P'_x(a,b,c)=P'_y(a,b,c)=P'_z(a,b,c)=0.

By early on September 11, the storm's movement was steady to the west-northwest, south of the ridge. At 06:00 UTC that day, the JMA upgraded Meranti to typhoon status, and shortly thereafter the JTWC followed suit. The storm's structure continued to improve, with increased outflow. A small eye across developed within the spiraling thunderstorms, signaling that Meranti was rapidly intensifying. At 06:00 UTC on September 12, the JTWC upgraded Meranti to a super typhoon, with 1-minute maximum sustained winds of 240 km/h (150 mph). Six hours later, the JTWC estimated 1-minute sustained winds of 285 km/h (180 mph), equivalent to Category 5 on the Saffir–Simpson scale, while noting "an extremely favorable environment", and that the eye became even more symmetric within intense convection. Outflow enhanced by a strong anticyclone over Meranti fueled the intensification, and the typhoon peaked in intensity on September 13 while passing through the Luzon Strait. Typhoon Meranti passing just south of Taiwan on September 14 The JMA estimated peak 10-minute sustained winds of 220 km/h (140 mph) and a minimum barometric pressure of 890 hPa (mbar; 26.28 inHg), while the JTWC estimated peak 1-minute sustained winds of 315 km/h (195 mph).
