Body image as risk factor for emotional and behavioral problems among Chinese adolescents

BMC Public Health, 2018
Background Being overweight and obesity during adolescence are worldwide public health problems. This study examined the relationship between actual weight, body image, and emotional and behavioral problems among Chinese adolescents.

On the connection between two equilibrium problems for cracked bodies in the cases of thin and volume rigid inclusions

Boundary Value Problems, 2019
We consider equilibrium problems for an inhomogeneous two-dimensional body with a crack and a rigid inclusion. The matrix of the body is assumed to be elastic. The boundary condition on the crack curve is an inequality describing mutual nonpenetration of

A general T-matrix approach applied to two-body and three-body problems in cold atomic gases

, 2012
We propose a systematic T-matrix approach to solve few-body problems with s-wave contact interactions in ultracold atomic gases. The problem is generally reduced to a matrix equation expanded by a set of orthogonal molecular states, describing external ...

Asymptotic Antipodal Solutions as the Limit of Elliptic Relative Equilibria for the Two- and n-Body Problems in the Two-Dimensional Conformal Sphere

Mathematics
We consider the two- and n-body problems on the two-dimensional conformal sphere MR2, with a radius R>0. We employ an alternative potential free of singularities at antipodal points.

Tardive Akathisia with Asymmetric and Upper-body Presentation: Report of Two Cases and Literature Review

Tremor and Other Hyperkinetic Movements, 2018
Background: Akathisia is an inner urge to move a body area with an objective motor component of restlessness. Tardive akathisia (TA) is usually bilateral with a predominant lower-body presentation.

Exact solutions for two-body problems in 1D deformed space with minimal length

, 2017
We reduce two-body problem to the one-body problem in general case of deformed Heisenberg algebra leading to minimal length.Two-body problems with delta and Coulomb-like interactions are solved exactly.

Alternative Fourier Expansions for Inverse Square Law Forces [PDF]

, 2001
Few-body problems involving Coulomb or gravitational interactions between pairs of particles, whether in classical or quantum physics, are generally handled through a standard multipole expansion of the two-body potentials.

Universal noise and Efimov physics [PDF]

, 2015
Probability distributions for correlation functions of particles interacting via random-valued fields are discussed as a novel tool for determining the spectrum of a theory. In particular, this method is used to determine the energies of universal N-body

Solution of Two-Body Bound State Problems with Confining Potentials

, 2010
The homogeneous Lippmann-Schwinger integral equation is solved in momentum space by using confining potentials. Since the confining potentials are unbounded at large distances, they lead to a singularity at small momentum.

On the existence of exotic and non-exotic multiquark meson states [PDF]

, 2007
To obtain an exact solution of a four-body system containing two quarks and two antiquarks interacting through two-body terms is a cumbersome task that has been tackled with more or less success during the last decades. We present an exact method for the
