Cell Reports, 2014 Summary: Age-associated thymic involution results in diminished T cell output and function in aged individuals. However, molecular mediators contributing to the decline in thymic function during early thymic involution remain largely unknown.

Real Hamiltonian forms of Hamiltonian systems [PDF]
, 2003 We introduce the notion of a real form of a Hamiltonian dynamical system in analogy with the notion of real forms for simple Lie algebras. This is done by restricting the complexified initial dynamical system to the fixed point set of a given involution.

Involutions on the Algebra of Physical Observables From Reality Conditions [PDF]
, 1995 Some aspects of the algebraic quantization programme proposed by Ashtekar are revisited in this article. It is proved that, for systems with first-class constraints, the involution introduced on the algebra of quantum operators via reality conditions can

Generalized Involution Models for Wreath Products [PDF]
, 2010 We prove that if a finite group $H$ has a generalized involution model, as defined by Bump and Ginzburg, then the wreath product $H \wr S_n$ also has a generalized involution model.

Polygons in Minkowski three space and parabolic Higgs bundles of rank two on CP^1
, 2012 Consider the moduli space of parabolic Higgs bundles (E,\Phi) of rank two on CP^1 such that the underlying holomorphic vector bundle for the parabolic vector bundle E is trivial.

Decomposing labeled interval orders as pairs of permutations [PDF]
, 2014 We introduce ballot matrices, a signed combinatorial structure whose definition naturally follows from the generating function for labeled interval orders. A sign reversing involution on ballot matrices is defined.

Involution and commutator length for complex hyperbolic isometries
, 2016 We study decompositions of complex hyperbolic isometries as products of involutions. We show that PU(2,1) has involution length 4 and commutator length 1, and that for all $n \geqslant 3$ PU($n$,1) has involution length at most 8.Comment: 32 pages, 22 ...
