Damped Bogoliubov excitations of a condensate interacting with a static thermal cloud

, 2000
We calculate the damping of condensate collective excitations at finite temperatures arising from the lack of equilibrium between the condensate and thermal atoms.

Core-sheath structured electrospun nanofibrous membranes for oil-water separation [PDF]

, 2016
In recent years, both the increasing frequency of oil spill accidents and the urgency to deal seriously with industrial oil-polluted water, encouraged material scientists to design highly efficient, cost effective oil-water separation technologies.

HAT-P-32b and HAT-P-33b: Two Highly Inflated Hot Jupiters Transiting High-jitter Stars [PDF]

, 2011
We report the discovery of two exoplanets transiting high-jitter stars. HAT-P-32b orbits the bright V = 11.289 late-F-early-G dwarf star GSC 3281-00800, with a period P = 2.150008 ± 0.000001 d.

No Conclusive Evidence for Transits of Proxima b in MOST photometry

, 2016
The analysis of Proxima Centauri's radial velocities recently led Anglada-Escud\'e et al. (2016) to claim the presence of a low mass planet orbiting the Sun's nearest star once every 11.2 days.

Thoughts of Leaving: An Exploration of Why New York City Middle School Teachers Consider Leaving Their Classrooms [PDF]

, 2012
This report explores the conditions under which middle-school teachers in New York City leave their schools, and the consequences of this turnover. The focus on middle schools stems from the widely-held view that the middle grades are a critical turning ...

Self-consistent calculation of the electron distribution near a Quantum-Point Contact in the integer Quantum Hall Effect

, 2006
In this work we implement the self-consistent Thomas-Fermi-Poisson approach to a homogeneous two dimensional electron system (2DES). We compute the electrostatic potential produced inside a semiconductor structure by a quantum-point-contact (QPC) placed ...

Phase separation and vortex states in binary mixture of Bose-Einstein condensates in the trapping potentials with displaced centers

, 2002
The system of two simultaneously trapped codensates consisting of $^{87}Rb$ atoms in two different hyperfine states is investigated theoretically in the case when the minima of the trapping potentials are displaced with respect to each other. It is shown
