Dynamical (super)symmetry vacuum properties of the supersymmetric Chern-Simons-matter model [PDF]
Phys. Rev. D 85, 125012 (2012), 2011 By computing the two-loop effective potential of the D=3 N=1 supersymmetric Chern-Simons model minimally coupled to a massless self-interacting matter superfield, it is shown that supersymmetry is preserved, while the internal U(1) and the scale symmetries are broken at two-loop order, dynamically generating masses both for the gauge superfield and for

Angewandte Chemie International Edition, Accepted Article.Isotope labelling, particularly with deuterium (2H), plays a critical role in drug discovery due to its ease of incorporation and its potential to switch unwanted metabolic transformations. Deuterium incorporation can enhance drug stability, affect pharmacokinetics, and alter metabolism pathways.

Vanishing Theorems and Syzygies for K3 Surfaces and Fano Varieties [PDF]
arXiv, 1996 In this article we prove some strong vanishing theorems on K3 surfaces. As an aplication of them, we obtain higher syzygy results for K3 surfaces and Fano varieties.

Period Stabilization in the Busse-Heikes Model of the Kuppers-Lortz Instability [PDF]
, 2000 The Busse-Heikes dynamical model is described in terms of relaxational and nonrelaxational dynamics. Within this dynamical picture a diverging alternating period is calculated in a reduced dynamics given by a time-dependent Hamiltonian with decreasing energy. A mean period is calculated which results from noise stabilization of a mean energy.

Angewandte Chemie International Edition, Accepted Article.We herein report the influence of the ligand framework on the isoselective ring‐opening polymerization (ROP) of rac‐β‐butyrolactone using highly active in situ generated salan [ONNO]H2 and salalen [ONNO]H rare‐earth metal complexes. The stereochemistry was found to be highly dependent on the ortho‐substituents, enabling the synthesis of either ...

Selfsimilar Domain Growth, Localized Structures and Labyrinthine Patterns in Vectorial Kerr Resonators [PDF]
, 1999 We study domain growth in a nonlinear optical system useful to explore different scenarios that might occur in systems which do not relax to thermodynamic equilibrium. Domains correspond to equivalent states of different circular polarization of light.

On a rigidity condition for Berwald Spaces [PDF]
, 2007 We show that which that for a Berwald structure, any Riemannian structure that is preserved by the Berwald connection leaves the indicatrix invariant under horizontal parallel transport. We also obtain the converse result: if $({\bf M},F)$ is a Finsler structure such that there exists a Riemannian structure that leaves invariant the indicatrix under ...
