text: The Regge symmetry is a set of remarkable relations between two tetrahedra
whose edge lengths are related in a simple fashion. It was first discovered as
a consequence of an asymptotic formula in mathematical physics. Here, we give
a simple geometric proof of Regge symmetries in Euclidean, spherical, and hyperbolic
geometry.

text: "* Understanding the mechanisms causing phenotypic differences between females
and males has long fascinated evolutionary biologists. An extensive literature
exists on animal sexual dimorphism but less information is known about sex differences
in plants, particularly the extent of geographical variation in sexual dimorphism
and its life‐cycle dynamics.\r\n* Here, we investigated patterns of genetically
based sexual dimorphism in vegetative and reproductive traits of a wind‐pollinated
dioecious plant, Rumex hastatulus, across three life‐cycle stages using open‐pollinated
families from 30 populations spanning the geographic range and chromosomal variation
(XY and XY1Y2) of the species.\r\n* The direction and degree of sexual dimorphism
was highly variable among populations and life‐cycle stages. Sex‐specific differences
in reproductive function explained a significant amount of temporal change in
sexual dimorphism. For several traits, geographical variation in sexual dimorphism
was associated with bioclimatic parameters, likely due to the differential responses
of the sexes to climate. We found no systematic differences in sexual dimorphism
between chromosome races.\r\n* Sex‐specific trait differences in dioecious plants
largely result from a balance between sexual and natural selection on resource
allocation. Our results indicate that abiotic factors associated with geographical
context also play a role in modifying sexual dimorphism during the plant life‐cycle."

text: In this paper we construct a family of exact functors from the category of
Whittaker modules of the simple complex Lie algebra of type to the category of
finite-dimensional modules of the graded affine Hecke algebra of type . Using
results of Backelin [2] and of Arakawa-Suzuki [1], we prove that these functors
map standard modules to standard modules (or zero) and simple modules to simple
modules (or zero). Moreover, we show that each simple module of the graded affine
Hecke algebra appears as the image of a simple Whittaker module. Since the Whittaker
category contains the BGG category as a full subcategory, our results generalize
results of Arakawa-Suzuki [1], which in turn generalize Schur-Weyl duality between
finite-dimensional representations of and representations of the symmetric group
.

text: Direct reciprocity is a powerful mechanism for the evolution of cooperation
on the basis of repeated interactions1,2,3,4. It requires that interacting individuals
are sufficiently equal, such that everyone faces similar consequences when they
cooperate or defect. Yet inequality is ubiquitous among humans5,6 and is generally
considered to undermine cooperation and welfare7,8,9,10. Most previous models
of reciprocity do not include inequality11,12,13,14,15. These models assume that
individuals are the same in all relevant aspects. Here we introduce a general
framework to study direct reciprocity among unequal individuals. Our model allows
for multiple sources of inequality. Subjects can differ in their endowments, their
productivities and in how much they benefit from public goods. We find that extreme
inequality prevents cooperation. But if subjects differ in productivity, some
endowment inequality can be necessary for cooperation to prevail. Our mathematical
predictions are supported by a behavioural experiment in which we vary the endowments
and productivities of the subjects. We observe that overall welfare is maximized
when the two sources of heterogeneity are aligned, such that more productive individuals
receive higher endowments. By contrast, when endowments and productivities are
misaligned, cooperation quickly breaks down. Our findings have implications for
policy-makers concerned with equity, efficiency and the provisioning of public
goods.
