Landau Damping for Non-Maxwellian Distribution Functions [PDF]

J. Plasma Phys. 91 (2025) E44
Landau damping is one of the cornerstones of plasma physics. In the context of the mathematical framework developed by Landau in his original derivation of Landau damping, we examine the solutions of the linear Vlasov-Poisson system for different equilibrium velocity distribution functions, such as the Maxwellian distribution, kappa distributions, and ...

The Bethe ansatz approach for factorizable centrally extended S-matrices

, 2007
We consider the Bethe ansatz solution of integrable models interacting through factorized $S$-matrices based on the central extention of the $\bf{su}(2|2)$ symmetry.

Arginine Accelerates Sulfur Fluoride Exchange and Phosphorus Fluoride Exchange Reactions between Proteins

Angewandte Chemie, Volume 136, Issue 47, November 18, 2024.
Introducing an arginine (Arg) residue adjacent to the latent bioreactive unnatural amino acid (Uaa) significantly accelerates both SuFEx and PFEx reaction rates between proteins. This offers a general and biocompatible strategy to harness these robust click chemistries for fundamental and applied biological research, applicable in vitro and in vivo ...

Effect of pressure-free heating curing time on bending property of 2D T700/E44 composites prepared by ICM

Materials Research Express, 2019
Six kinds of 2D T700/E44 composites with pressure-free curing times of 40 min, 60 min, 80 min, 100 min, 120 min and 140 min are prepared by improved compression molding process (ICM). The macroscopic morphology of the composites is satisfactory. The microstructure observation and bending performance tests show that composites have poor infiltration ...

The Role of Lithium Ions on the Solubility of K4E4 in Ethylenediamine and the Oxidation of the Zintl Anions [E4]4− (E = Ge, Sn, Pb) as well as [Ge9]4−

Chemistry – A European Journal, Volume 31, Issue 26, May 8, 2025.
The solubility of K4Ge4, K4Sn4, and K4Pb4 phases and oxidation of comprised four‐atom clusters in ethylenediamine (en) is induced by the addition of LiCl. The 119Sn NMR spectra of [Sn9]4− with Li+ and K+ counterions indicate a cation‐dependent change in both the chemical shift and coupling constant, strongly suggesting K+/[Sn9]4− ion pairing, which is ...

Multiplet Effects in the Quasiparticle Band Structure of the $f^1-f^2$ Anderson Model

, 1994
In this paper, we examine the mean field electronic structure of the $f^1-f^2$ Anderson lattice model in a slave boson approximation, which should be useful in understanding the physics of correlated metals with more than one f electron per site such as ...

Joint Wire Cutting with Non‐Maximally Entangled States

Advanced Quantum Technologies, Volume 8, Issue 5, May 2025.
Wire cutting decomposes large quantum circuits into smaller subcircuits by severing connecting wires, enabling execution on multiple distributed devices. This study employs non‐maximally entangled (NME) states in joint wire cuts to reduce their overhead.

Strange magnification pattern in the large separation lens SDSS J1004+4112 from optical to X-rays [PDF]

, 2006
We present simultaneous XMM-Newton UV and X-ray observations of the quadruply lensed quasar SDSS J1004+4112 (RBS 825). Simultaneously with the XMM-Newton observations we also performed integral field spectroscopy on the two closest lens images A and B using the Calar Alto PMAS spectrograph.

Exopolysaccharides produced by Bifidobacterium longum IPLA E44 and Bifidobacterium animalis subsp. lactis IPLA R1 modify the composition and metabolic activity of human faecal microbiota in pH-controlled batch cultures [PDF]

International Journal of Food Microbiology, 2009
Exopolysaccharides (EPS) isolated from two Bifidobacterium strains, one of human intestinal origin (Bifidobacterium longum subsp. longum IPLA E44) and the other from dairy origin (Bifidobacterium animalis subsp. lactis IPLA R1), were subjected to in vitro chemically simulated gastrointestinal digestion, which showed the absence of degradation of both ...

Sex Differences in Cortical Thickness and Neuropsychiatric Symptom Burden Based on APOE4 Homozygosity in Alzheimer's Disease

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, Volume 198, Issue 2, March 2025.
ABSTRACT Sex differences in patterns of cortical thickness and neuropsychiatric symptom (NPS) burden were examined among individuals with Alzheimer's disease (AD) and two copies (homozygote carriers) of the e4 allele of the apolipoprotein gene (APOE). A total of 752 participants with a clinical etiologic diagnosis of AD were selected from the National ...
