An energy-based approach has been used to investigate the seismic behavior of code-designed asymmetric-plan systems. The systems considered in this investigation had large eccentricities in both directions, were designed for bidirectional earthquake loading, and their responses were computed with both components of ground motion acting simultaneously. The presented results demonstrate that the ...

In this paper we introduce two symmetric variants of amenability, symmetric module amenability and symmetric Connes amenability. We determine symmetric module amenability and symmetric Connes amenability of some concrete Banach algebras. Indeed, it is shown that $ell^1(S)$ is  a symmetric $ell^1(E)$-module amenable if and only if $S$ is amenable, where $S$ is an inverse semigroup with subsemigr...

We present a design for an atom chip trap that uses the time-orbiting potential technique. The offers several advantages compared to other chip-trap methods. It simple crossed-wire pattern on chip, along with rotating bias field. is naturally close spherically symmetric, and it can be modified exactly symmetric in quadratic order of coordinates. Loading from magneto-optical facilitated because ...

let $rin textbf{c}^{mtimes m}$ and $sin textbf{c}^{ntimes n}$ be nontrivial involution matrices; i.e., $r=r^{-1}neq pm~i$ and $s=s^{-1}neq pm~i$. an $mtimes n$ complex matrix $a$ is said to be an $(r, s)$-symmetric ($(r, s)$-skew symmetric) matrix if $ras =a$ ($ ras =-a$). the $(r, s)$-symmetric and $(r, s)$-skew symmetric matrices have a number of special properties and widely used in engi...

We investigate how magnetic reconnection is influenced by an inflow of a dense cold ion population. compare two 2.5D Particle-In-Cell simulations, one containing the population and without. find that influences process on both global kinetic scales, dominant contribution can be explained through mass-loading. provide analysis these multiscale changes are related processes in diffusion region, s...

BACKGROUND CONTEXT Recurrent low back pain (LBP) is a common and costly problem that might be related to increased spine loads in those with LBP. However, we know little about how the spine is loaded when those with LBP perform lifting exertions. PURPOSE Document spine loading patterns of patients with LBP performing symmetric and asymmetric lifting exertions compared with asymptomatic indivi...

Cold-formed steel C- and Z-section beams are widely used in light gauge building systems as flexural members. In their applications members, mono-symmetric C-sections point-symmetric Z-sections often subjected to transverse loads eccentric the shear centre, leading combined bending torsion actions. However, research design methods for cold-formed limited. Hence this has investigated structural ...
