Josephson effect in graphene SBS junctions
, 2007 We study Josephson effect in graphene superconductor- barrier- superconductor junctions with short and wide barriers of thickness $d$ and width $L$, which can be created by applying a gate voltage $V_0$ across the barrier region.

Curb-to-Barrier Face Distance Variation an a TB51 Bridge Barrier Crash Test Simulation
Archives of Civil Engineering, 2017 This paper addresses the problem of road safety regarding barrier placement as relative to the curb. A short summary of existing regulations is presented. Numerical simulations using the explicit finite element system Ls-Dyna are shown.

Current-Phase Relation of a Bose-Einstein Condensate Flowing Through a Weak Link
, 2009 We study the current-phase relation of a Bose-Einstein condensate flowing through a repulsive square barrier by solving analytically the one dimensional Gross-Pitaevskii equation. The barrier height and width fix the current-phase relation $j(\delta\phi)$

Self-Chaotization in Coupled Optical Waveguides [PDF]
, 2008 We consider theoretically two coupled optical waveguides with a varying barrier height along the waveguides direction. The barrier could be constructed by the elongated island with a reduced refractive index (which acts as a potential barrier), such that

Using Optimization to Break the Epsilon Barrier: A Faster and Simpler Width-Independent Algorithm for Solving Positive Linear Programs in Parallel [PDF]
ACM-SIAM Symposium on Discrete Algorithms, 2014 We study the design of nearly-linear-time algorithms for approximately solving positive linear programs. Both the parallel and the sequential deterministic versions of these algorithms require $\tilde{O}(\varepsilon^{-4})$ iterations, a dependence that ...

Inflammatory cytokines directly disrupt the bovine intestinal epithelial barrier
Scientific Reports, 2022 The small intestinal mucosa constitutes a physical barrier separating the gut lumen from sterile internal tissues. Junctional complexes between cells regulate transport across the barrier, preventing water loss and the entry of noxious molecules or ...

Spherical model of the Stark effect in external scalar and vector fields
, 2010 The Bohr-Sommerfeld quantization rule and the Gamow formula for the width of quasistationary level are generalized by taking into account the relativistic effects, spin and Lorentz structure of interaction potentials.

Alpha decay and proton-neutron correlations
, 2003 We study the influence of proton-neutron (p-n) correlations on alpha-decay width. It is shown from the analysis of alpha Q values that the p-n correlations increase the penetration of the alpha particle through the Coulomb barrier in the treatment ...

Hartman effect and dissipative quantum systems
, 2012 The dwell time for dissipative quantum system is shown to increase with barrier width. It clearly precludes Hartman effect for dissipative systems. Here calculation has been done for inverted parabolic potential barrier.Comment: article consists of 5 ...
