Discordance Between Systemic Lupus Erythematosus Disease Activity Index Domain Weights and Their Association With Organ Damage Accrual

open access: yesArthritis Care &Research, EarlyView.
Objective Studies of damage accrual in patients with systemic lupus erythematosus (SLE) show associations with disease activity measured by the SLE Disease Activity Index 2000 (SLEDAI‐2K), but these associations are imperfect. SLEDAI scores are powerfully influenced by weightings (1–8) assigned to each domain.

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.

Iteration of λ-complete forcing notions not collapsing λ+

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2001
We look for a parallel to the notion of “proper forcing” among λ-complete forcing notions not collapsing λ+. We suggest such a definition and prove that it is preserved by suitable iterations.

Adaptive Observer for Coupled Wave PDE and Infinite ODE With Sampled Data and Unknown Input: Application to Brain Hemodynamics Estimation

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
This article proposes a convergent adaptive observer for a damped wave PDE and an infinite‐dimensional ODE coupled in cascade using sampled‐in‐space ODE state measurements. The proposed observer estimates the distributed states of the PDE and ODE along with unknown PDE parameters and spatial input.

First observation of Λ c (2595)+ → Λ c + π 0 π 0 $$ {\Lambda}_c^{+}{\pi}^0{\pi}^0 $$ and Λ c (2625)+ → Λ c + π 0 π 0 $$ {\Lambda}_c^{+}{\pi}^0{\pi}^0 $$

open access: yesJournal of High Energy Physics
By analysing e + e − annihilation data corresponding to an integrated luminosity of 368.48 pb −1 collected at the centre-of-mass energies of s $$ \sqrt{s} $$ = 4.918 and 4.951 GeV with the BESIII detector, we report the first observation of Λ c (2595 ...

On approximation f by (α,β,γ)-Baskakov Operators

open access: yesJournal of Al-Qadisiyah for Computer Science and Mathematics, 2017
  In the present paper, we study some application properties of the approximation for the sequences  and   . These sequences depend on the arbitrary (but fixed) parameters  and . Here, we study the effect of these parameters on tends speed of the two families of operators  and  and the CPU times which are occurring on the approximation by a choosing ...

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

open access: yesAdvanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Novel constraints on $$\varLambda \text{-- }\overline{\varLambda }$$ Λ -- Λ ¯ and $$p\text{-- }\overline{\varLambda }$$ p -- Λ ¯ interactions using correlation data

open access: yesEuropean Physical Journal C: Particles and Fields
The interaction between baryons and antibaryons ( ) remains a fundamental topic in hadronic physics, particularly due to its potential to reveal exotic bound states such as baryonia.

FUNGSI DAN PEMERIKSAAN LIMFOSIT γδT (Functions and Examination of γδT lymphocytes)

open access: yesINDONESIAN JOURNAL OF CLINICAL PATHOLOGY AND MEDICAL LABORATORY, 2018
T lymphocytes most have TCR α and β chains. However, TCR formed from γ and δ chains determine a new subset of T lymphocytes. γδTCR specific to different types of ligands, including bacterial phosphoantigen, nonclassical MHC-I molecules and unprocessed protein.
