Ultracold Neutral Plasmas [PDF]

open access: yesAIP Conference Proceedings, 2006
Ultracold neutral plasmas, formed by photoionizing laser-cooled atoms near the ionization threshold, have electron temperatures in the 1-1000 kelvin range and ion temperatures from tens of millikelvin to a few kelvin. They represent a new frontier in the

Neutral Operator and Neutral Differential Equation [PDF]

open access: yesAbstract and Applied Analysis, 2011
In this paper, we discuss the properties of the neutral operator (Ax)(t) = x(t) − cx(t − δ(t)), and by applying coincidence degree theory and fixed point index theory, we obtain sufficient conditions for the existence, multiplicity, and nonexistence of (positive) periodic solutions to two kinds of second‐order differential equations with the prescribed

Neutral Fermion Excitations in the Moore-Read state at \nu=5/2 [PDF]

open access: yes, 2011
We present evidence supporting the weakly paired Moore-Read phase in the half-filled second Landau level, focusing on some of the qualitative features of its excitations.

P-resonant control for the neutral point of three phase inverter [PDF]

open access: yes, 2014
In this project, a Proportional resonant (PR) current controller is proposed to maintain a balanced neutral point for a three-phase four wire inverter, which can be used in microgrid applications. The neutral-point circuit consists of a conventional

Production and Optimization of Xylanase and α-Amylase from Non-Saccharomyces Yeasts (Pichia membranifaciens)

open access: yesJournal of Pure and Applied Microbiology, 2021
The xylanolytic and amylolytic yeasts were qualitatively determined by Cong red xylan agar and soluble starch agar plates, respectively. The most xylanase and α-amylase inducible strain (AUN-02) was selected and identified using PCR amplification of 26S ...

Second-Order Neutral Differential Equations with Distributed Deviating Arguments: Oscillatory Behavior

open access: yesMathematics, 2023
In this paper, new criteria for a class oscillation of second-order delay differential equations with distributed deviating arguments were established. Our method mainly depends on making sharper estimates for the non-oscillatory solutions of the studied

Nonexotic Neutral Gauge Bosons [PDF]

open access: yes, 2002
We study theoretical and experimental constraints on electroweak theories including a new color-singlet and electrically-neutral gauge boson. We first note that the electric charges of the observed fermions imply that any such Z' boson may be described ...

Dynamics of edge Majorana fermions in $\nu=\frac{5}2$ fractional quantum Hall effects [PDF]

open access: yes, 2007
Commencing with the composite fermion description of the $\nu=5/2$ fractional quantum Hall effect, we study the dynamics of the edge neutral Majorana fermions.
