Determining the structure of the superconducting gap in Cu_{2}O_{3} 2-leg ladder materials

open access: yes, 1996
Superconductivity has been recently observed in Sr_{0.4}Ca_{13.6}Cu_{24}O_{41.84} which contains quasi-one-dimensional Cu_{2}O_{3} 2-leg ladders. If, as suggested by some theories, the superconductivity arises from these 2-leg ladders, it will be ...

Treatment of the Fractional Curve of Adult Scoliosis With Circumferential Minimally Invasive Surgery Versus Traditional, Open Surgery: An Analysis of Surgical Outcomes. [PDF]

open access: yes, 2018
Study Design:Retrospective, multicenter review of adult scoliosis patients with minimum 2-year follow-up. Objective:Because the fractional curve (FC) of adult scoliosis can cause radiculopathy, we evaluated patients treated with either circumferential ...

Ground-state phases of rung-alternated spin-1/2 Heisenberg ladder

open access: yes, 2015
The ground-state phase diagram of Heisenberg spin-1/2 system on a two-leg ladder with rung alternation is studied by combining analytical approaches with numerical simulations.

Reducing switching losses through MOSFET-IGBT combination [PDF]

open access: yes, 2008
This paper introduces a configuration aimed at switching losses reduction trough a power leg constructed by combining a MOSFET and an IGBT. The combined use of these different switches leads to the turn-on losses reduction trough the use of the faster ...

Correlations and confinement of excitations in an asymmetric Hubbard ladder

open access: yes, 2017
Correlation functions and low-energy excitations are investigated in the asymmetric two-leg ladder consisting of a Hubbard chain and a noninteracting tight-binding (Fermi) chain using the density matrix renormalization group method.

Coupling mechanisms between the contralateral legs of a walking insect (Carausius morosus) [PDF]

open access: yes, 1989
Cruse H, Knauth A. Coupling mechanisms between the contralateral legs of a walking insect (Carausius morosus). The journal of experimental biology. 1989;144(1):199-213.Interactions between contralateral legs of stick insects during walking were examined ...

Breathers and Raman scattering in a two-leg ladder with staggered Dzialoshinskii-Moriya interaction

open access: yes, 2007
Recent experiments have revealed the role of staggered Dzialoshinskii-Moriya interaction in the magnetized phase of an antiferromagnetic spin 1/2 two-leg ladder compound under a uniform magnetic field.

Leg Coordination during Walking in Insects [PDF]

open access: yes, 2013
Locomotion depends on constant adaptation to different requirements of the environment. An appropriate temporal and spatial coordination of multiple body parts is necessary to achieve a stable and adapted behavior.

Non-equilibrium dynamics in Bose-Hubbard ladders

open access: yes, 2012
Motivated by a recent experiment on the non-equilibrium dynamics of interacting bosons in ladder-shaped optical lattices, we report exact calculations on the sweep dynamics of Bose-Hubbard systems in finite two-leg ladders.

Dynamics of doublon-holon pairs in Hubbard two-leg ladders

open access: yes, 2012
The dynamics of holon-doublon pairs is studied in Hubbard two-leg ladders using the time-dependent Density Matrix Renormalization Group method. We find that the geometry of the two-leg ladder, that is qualitatively different from a one-dimensional chain ...
