The in vitro and in vivo ability of benzodiazepines to inhibit specific 3H-diazepam binding correlated with their ability to increase punished responding in a conflict situation. Conflict and foot ...shock, the punishing stimulus used in most conflict procedures, also altered 3H-diazepam binding. These data implicate 3H-diazepam binding sites in mediating at least some of the anxiolytic properties of benzodiazepines and suggest the existence of some endogenous substance which might be involved in the etiology of anxiety.
This study examined to what extent gender, occupation and family situations influenced the occurrence and frequency of overnight work-related travel that US employees experienced. Unlike previous ...work, the data analysis allowed for differentiation of the factors associated with being in jobs with any overnight travel demand and the factors related to how frequently respondents travelled. This study particularly tested the hypotheses of occupational segregation and family demands, separately by gender. Consistent with the occupational segregation hypothesis, the occurrence and frequency of work travel varied across the types of occupation and men had a higher chance both to be in jobs with travel overnight demands and to travel more often than women did. The family demands hypothesis was supported by the findings that living with a spouse or partner and taking responsibility for a family member in need of extensive care were associated with the prevalence of work travel.
The azimuthal correlations of D mesons with charged particles were measured with the ALICE apparatus in pp collisions at Formula: see text and p-Pb collisions at Formula: see text at the Large Hadron ...Collider. Formula: see text, Formula: see text, and Formula: see text mesons and their charge conjugates with transverse momentum Formula: see text and rapidity in the nucleon-nucleon centre-of-mass system Formula: see text (pp collisions) and Formula: see text (p-Pb collisions) were correlated to charged particles with Formula: see text. The yield of charged particles in the correlation peak induced by the jet containing the D meson and the peak width are compatible within uncertainties in the two collision systems. The data are described within uncertainties by Monte-Carlo simulations based on PYTHIA, POWHEG, and EPOS 3 event generators.

Magnetic reconnection is experimentally investigated in laser produced plasmas. By irradiating a solid target with a high-power laser beam, a magnetic bubble is generated due to the Biermann effect. ...When two laser beams with finite focal spot displacements are utilized, two magnetic bubbles are generated, and the magnetic reconnection can take place. We measure the spatial and temporal plasma evolutions with optical diagnostics using framing camera. We observed the plasma jets, which are considered to be reconnection out flows. Spatial and temporal scales of the plasma jets are much larger than those of laser. The magnetic reconnection time has been estimated from the expansion velocity, which is consistent with the Sweet-Parker model.
Several extensions of the Standard Model predict the production of dark matter particles at the LHC. An uncharted signature of dark matter particles produced in association with VV=W^{±}W^{∓} or ZZ ...pairs from a decay of a dark Higgs boson s is searched for using 139 fb^{-1} of pp collisions recorded by the ATLAS detector at a center-of-mass energy of 13 TeV. The s→V(qqover ¯)V(qqover ¯) decays are reconstructed with a novel technique aimed at resolving the dense topology from boosted VV pairs using jets in the calorimeter and tracking information. Dark Higgs scenarios with m_{s}>160 GeV are excluded.
