We calculated, within the Gross-Pitaevskii formalism, the critical number of atoms for Bose-Einstein condensates with two-body attractive interactions in cylindrical traps with different frequency ratios. In particular, by using the trap geometries considered by Roberts et al. @Phys. Rev. Lett. 86, 4211 ~2001!#, we show that the theoretical maximum critical numbers are given approximately by Nc...

Recent studies have implicated the classical neurotransmitters GABA and glutamate in the regulation of neural progenitor proliferation. We now show that GABA and glutamate have opposite effects on the two neural progenitor populations in the ventricular zones (VZs) and subventricular zones (SVZs) of the embryonic cerebrum. Application of either molecule to organotypic slice cultures dramaticall...

Netrin1 has been proposed to act from the floor plate (FP) as a long-range diffusible chemoattractant for commissural axons in the embryonic spinal cord. However, netrin1 mRNA and protein are also present in neural progenitors within the ventricular zone (VZ), raising the question of which source of netrin1 promotes ventrally directed axon growth. Here, we use genetic approaches in mice to sele...

Early cortical progenitor cells of the ventricular zone (VZ) differ from later progenitor cells of the subventricular zone (SVZ) in cell-type generation and their level of epidermal growth factor receptors (EGFRs). To determine whether differences in their behavior are causally related to EGFR number/density, we introduced extra EGFRs into VZ cells with a retrovirus in vivo and in vitro. This r...

Abstract The one-loop contributions to the trilinear neutral gauge boson couplings $$ZZV^*$$ Z V ? ( $$V=\gamma ,Z,Z'$$ = ? , ? ), parametrized in terms of one CP...

ABSTRACT Recent studies discovered that part of the Gould Belt belongs to a 2.7 kpc-long coherent, thin wave consisting chain clouds, where damped undulation pattern has been identified from spatial arrangement clouds. We use proper motions young stellar objects anchored inside clouds study kinematic structure Radcliffe in terms vz, and identify damped, wave-like vz space, which we call ‘veloci...

We perform a case study on the evolution of current sheet in different regions around dipolarization front (DF), including magnetic-dip preceding DF, at and magnetic pileup region (MPR) behind DF based magnetospheric multiscale (MMS) observation July 31, 2017. In this event, MMS1 stays inside during whole bursty bulk flow (BBF) interval. Our analysis reveals that cross-tail is rolled up, signif...

Introduction: Methane is one of the most widely used gases in industries with a high flammability potential. This study aimed to evaluate the efficiency of ventilation systems installed on methane valve pits based on hazardous areas classification. Material and Methods: This study was implemented in a steel industry in Qom Province in 2019. The tools used in this study were a DELTA OHM pitot t...

In this paper, the variations of ionospheric irregularities have been studied using C/NOFS, ground-based GNSS and magnetometer measurements in Africa during St. Patrick geomagnetic storm March 17, 2013. The latitudinal distribution was examined GNSS-ROTI maps covering longitude 25°–45°E. Longitudinal characteristics were also investigated along with equatorial plasma bubbles (EPBs) vertical dri...
