Brane to bulk supersymmetry breaking and radion force at micron distances [PDF]

, 2002
We study mediation of supersymmetry breaking in the bulk, in models with primordial supersymmetry breaking on D-branes at the string scale, in the TeV region. We compute the gravitino and scalar masses up to one-loop level, as well as the radion coupling

Current reversals in a rocking ratchet: dynamical vs symmetry-breaking mechanisms [PDF]

, 2010
Directed transport in ratchets is determined by symmetry-breaking in a system out of equilibrium. A hallmark of rocking ratchets is current reversals: an increase in the rocking force changes the direction of the current.

Experimental Analysis of the Tensile Properties of Painting Canvas

AUTEX Research Journal, 2016
In this paper, the practical application of uniaxial testing of painting canvas for determining its mechanical properties is presented. Painting canvases have a complex composite structure whose mechanical properties are considerably improved in relation

Critical coupling for dynamical chiral-symmetry breaking with an infrared finite gluon propagator [PDF]

, 1996
We compute the critical coupling constant for the dynamical chiral-symmetry breaking in a model of quantum chromodynamics, solving numerically the quark self-energy using infrared finite gluon propagators found as solutions of the Schwinger-Dyson ...

Which part of a chain breaks

, 2018
This work investigates the dynamics of a one-dimensional homogeneous harmonic chain on a horizontal table. One end is anchored to a wall, the other (free) end is pulled by external force.

Abelian Hidden Sectors at a GeV [PDF]

, 2009
We discuss mechanisms for naturally generating GeV-scale hidden sectors in the context of weak-scale supersymmetry. Such low mass scales can arise when hidden sectors are more weakly coupled to supersymmetry breaking than the visible sector, as happens ...

Charge-Symmetry Breaking and the Two-Pion-Exchange Two-Nucleon Interaction

, 2003
Charge-symmetry breaking in the nucleon-nucleon force is investigated within an effective field theory, using a classification of isospin-violating interactions based on power-counting arguments.
