This workshop continues the series of conferences devoted to non-neutral and related plasma phenomena. It will cover topics such as
Confinement and dynamics of non-neutral plasma.
Therapeutic brain modulation with targeted large neutral amino acid supplements in the Pah-enu2 phenylketonuria mouse model
phenylketonuria inborn error of metabolism large neutral amino acids mouse model neurotransmitters brain biochemistry treatment
2018/12/18
Background: Phenylketonuria treatment consists mainly of a Phe-restricted diet, which leads to suboptimal neurocognitive and psychosocial outcomes. Supplementation of large neutral amino acids (LNAAs)...
Transcriptome sequencing reveals both neutral and adaptive genome dynamics in a marine invader
adaptation invasive species natural selection contemporary evolution
2015/12/11
Species invasions cause significant ecological and economic damage, and genetic information is important to understanding and managing invasive species. In the ocean,
many invasive species have...
The effect of the stratospheric QBO on the neutral density of the D region
QBO Multiple regression Lower Ionosphere Stratosphere
2015/8/14
A multiple regression model, which defines relationship between two variables, is used to perform a statistical analysis of the relationship between the stratospheric QBO and the neutral density of th...
On Dirichlet eigenvectors for neutral two-dimensional Markov chains
Hahn polynomials two-dimensional difference equation neutral Markov chain multitype population dynamics Dirichlet eigenvector Dirichlet eigenvalue quasi-stationary distribution Yaglom limit coexistence
2015/7/7
We consider a general class of discrete, two-dimensional Markov chains modeling the dynamics of a population with two types, without mutation or immigration, and neutral in the sense that type has no ...
We present high-resolution H41α hydrogen recombination line observations of the 12 (3 pc) region surrounding Sagittarius A* (Sgr A*) at 92 GHz using the Millimeter Array at the Owens Valley Radio Obse...
ELECTROWEAK CORRECTIONS TO PARITY-VIOLATING NEUTRAL CURRENT SCATTERING
Resonance weak neutral axis vector transitional form axial vector electroweak radiation elastic electron scattering
2014/12/23
We analyze the degree to which parity-violating (PV) electroexcitation of the Δ(1232) resonance may be used to extract the weak neutral axial vector transition form factors. We find that the axial vec...
We have observed a 3° × 3° area centered on the M81/M82 group of galaxies using the Robert C. Byrd Green Bank Telescope in a search for analogs to the high-velocity clouds of neutral hydrogen found ar...
DETECTION OF DIFFUSE NEUTRAL INTRAGROUP MEDIUM IN HICKSON COMPACT GROUPS
new Green Bank Telescope gas mass fraction
2014/12/20
We present new Green Bank Telescope (GBT) 21 cm neutral hydrogen (H I) observations of a complete distance-limited sample of 22 Hickson Compact Groups (HCGs) with at least four true members. We detect...
Long Range Electromagnetic Effects involving Neutral Systems and Effective Field Theory
Electromagnetic scattering particles particles quantum mechanics the particle spins
2014/12/19
We analyze the electromagnetic scattering of massive particles with and without spin wherein one particle (or both) is electrically neutral. Using the techniques of effective field theory, we isolate ...
Multiwavelength Study Of The Distribution Of Neutral Gas In And Around Galaxies And Groups Of Galaxies
Pure sciences Absorption Compact groups Galaxy evolution Hydrogen Lyman alpha
2014/12/9
We study the distribution and nature of neutral hydrogen in various environments. We start by exploring the disk and halos of galaxies in Chapter 1. Our sample consists of 23 sightlines through 15 low...

Molecular-level mechanisms of quartz dissolution under neutral and alkaline conditions in the presence of electrolytes
quartz dissolution molecular-level mechanisms electrolytes pH conditions quantum chemistry calculation
2017/4/11
The mechanisms of quartz dissolution are affected intricately by pH conditions and electrolyte types. Most previous
studies have focused on the mechanisms of quartz dissolution under one specific con...
The role of velocity-neutral creep on the modulation of tectonic tremor activity by periodic loading
velocity-neutral creep on the modulation tectonic tremor activity periodic loading
2014/4/15
Slow slip events and associated non-volcanic tremors are sensitive to oscillatory stress perturbations, such as those induced by tides or seismic surface waves. Slow slip events and tremors are though...
The roles of charge exchange and dissociation in spreading Saturn's neutral clouds
roles of charge exchange dissociation spreading Saturn's neutral clouds Space Physics
2012/4/19
Neutrals sourced directly from Enceladus's plumes are initially confined to a dense neutral torus in Enceladus's orbit around Saturn. This neutral torus is redistributed by charge exchange, impact/pho...
