Nuclear-resonant electron scattering

open access: yes, 2008
We investigate nuclear-resonant electron scattering as occurring in the two-step process of nuclear excitation by electron capture (NEEC) followed by internal conversion. The nuclear excitation and decay are treated by a phenomenological collective model

Ecotoxicological Evaluation of Organic Sunscreens Used Worldwide, Alone and in Mixture, on Terrestrial Plants

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT The environmental hazards of sunscreens are discussed worldwide. However, there are few ecotoxicological studies on these compounds alone for edaphic organisms, and none for their mixtures. Avobenzone (1 and 10 ng/L), octocrylene (10 and 100 μg/L), and oxybenzone (2 and 20 μg/L), alone and in binary combinations (between the lowest and the ...

Improved Multipolar Hardy Inequalities

open access: yes, 2013
In this paper we prove optimal Hardy-type inequalities for Schrodinger operators with positive multi-singular inverse square potentials of the form $$A_{\lambda } := -\Delta- \lambda \displaystyle\sum _{1\leq i 0.$$ More precisely, we show that A λ is nonnegative in the sense of L 2 quadratic forms in \({\mathbb{R}}^{N}\), if and only if ...

Observation of a $\gamma$-band based on two-quasiparticle configuration in $^{70}$Ge

open access: yes, 2016
The structure of $^{70}$Ge has been studied through in-beam gamma ray spectroscopy. A new band structure is identified that leads to forking of the ground-state band into two excited bands.

pyDiSCaMB: enabling the use of multipolar scattering factors in Phenix

open access: yesJournal of Applied Crystallography, EarlyView.
pyDiSCaMB provides an interface between cctbx and DiSCaMB. The former drives Phenix and the latter provides multipolar parameterization of scattering, thus enabling multipolar modelling in Phenix.Multipolar scattering models, such as the transferable aspherical atom model, account for atomic chemical interactions and provide a more accurate ...

Technology for Whom and for What? A Global South View of Tech Diplomacy

open access: yesGlobal Policy, EarlyView.
ABSTRACT International politics is linked to its technical‐social character. Also, technology is socially constructed and thereby not entirely neutral or impartial. A tech‐driven geopolitical landscape has been a defining feature of contemporary world politics.

Various Aspects of the Multipolarity within the World Economic System

open access: yes, 2015
The key aspects of the world economy’s transformation in the context of the multipolar world formation are studied in the article. Various kinds of economic multipolarity are analyzed. There is specially emphasized the wide range of multipolarity’s forms

Isospin Character of the Pygmy Dipole Resonance in 124Sn

open access: yes, 2010
The pygmy dipole resonance has been studied in the proton-magic nucleus 124Sn with the (a,a'g) coincidence method at E=136 MeV. The comparison with results of photon-scattering experiments reveals a splitting into two components with different structure:
