Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Critical conditions and grain growth model for dynamic recrystallization of Cu-Ni-Si alloy

open access: yesResults in Physics, 2019
Hot compression tests of Cu-Ni-Si alloy with high Ni and Si contents were performed at the deformation temperatures of 750–950 °C, and the strain rates of 0.01–10 s−1 on a Gleeble-3800 thermo-mechanical simulator.

Refinement of amino‐acid conformation vs. difference density maps in time‐resolved serial femtosecond crystallography data analysis

open access: yesFEBS Open Bio, EarlyView.
The dFoCC pipeline starts with observed DED and resting‐state coordinates, which are then used to generate a library of triggered states. Correlation analysis of the calculated DED features of each candidate vs observed DED permits quantitative evaluation of candidate structural quality.

Optimizing photoexcitation conditions for time‐resolved X‐ray solution scattering experiments

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering (TR‐XSS) is a powerful technique to visualize how proteins change their structure in real time after light activation. Selecting the right laser photoexcitation conditions—fluence, excitation geometry, and sample refresh rate—is critical to maximize the experimental signal while avoiding unwanted side effects ...

Some Achievements on Two Variable σ-Derivations

open access: yesJournal of Mathematical Extension, 2014
. Let B and A be two Banach algebras and M be a Banach Bbimodule. Suppose that σ : A→B is a linear mapping. A bilinear map φ : A×A → M is called a two variable σ-derivation whenever φ(ab, c) = φ(a, c)σ(b) + σ(a)φ(b, c) and φ(a, bc) = φ(a, b)σ(c) + σ(b)

Observation of the ψð3686ß decays into Σ+ Σ - ω and Σ+ Σ - φ

open access: yes, 2023
Based on (2712.4 +/- 14.3) x 106 events recorded at the psi(3686) nominal mass collected with the BESIII detector operating at the BEPCII collider, the psi(3686) -> E +/- E over bar -omega and E +/- E over bar -phi decays are observed for the first time with statistical significances of 13.8 sigma and 7.6 sigma, respectively.

παρακοπὰ, bad coin in Aeschylus

open access: yesHumanitas, 2021
El v.223 de Agamenón de Esquilo trata un tema central en la obra, la cadena de errores en un mismo linaje, y el término parakopa interpretado en su significado literal, que está relacionado con la acuñación de moneda, aporta un significado adicional que se va desarrollando a lo largo de la obra.

Unraveling 4‐Phenylbutyrate's Therapeutic Role in SLC6A1 Disorders: Pharmacochaperoning Over HDAC Inhibition

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Variants in SLC6A1, encoding the GABA transporter 1 (GAT‐1), cause epilepsy, autism spectrum disorder, and developmental delay via loss of GABA uptake, impaired trafficking, and ER retention. We previously found that 4‐Phenylbutyrate (PBA), an FDA‐approved drug, restores GABA uptake and reduces seizures in SLC6A1‐related disorders ...

关于弱-可加空间的逆极限

open access: yes四川大学学报. 自然科学版, 2000
主要证明了如下两个结果 :设X =lim← {Xσ,πσρ,Σ}并且每个πσ 是开满映射 ,(1)如果X是 |Σ| 仿紧的且每个Χσ 是正规弱 θ 可加的 ,则X是正规弱 θ 可加的 ;(2 )如果X是遗传|Σ| 仿紧的且每个Xσ 是遗传正规的遗传弱 θ 可加空间 ,则X是遗传正规的遗传弱 θ 可加空间 .

A Q‐Learning Algorithm to Solve the Two‐Player Zero‐Sum Game Problem for Nonlinear Systems

open access: yesInternational Journal of Adaptive Control and Signal Processing, Volume 39, Issue 3, Page 566-581, March 2025.
A Q‐learning algorithm to solve the two‐player zero‐sum game problem for nonlinear systems. ABSTRACT This paper deals with the two‐player zero‐sum game problem, which is a bounded L2$$ {L}_2 $$‐gain robust control problem. Finding an analytical solution to the complex Hamilton‐Jacobi‐Issacs (HJI) equation is a challenging task.
