Soluble SORL1 in cerebrospinal fluid as a marker for functional impact of rare SORL1 variants

Alzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION The sortilin‐related receptor (SORL1) directs APP and Aβ trafficking within the retromer pathway. Cleavage at the cell surface releases soluble SORL1 (sSORL1) into cerebrospinal fluid (CSF). We examined whether CSF‐sSORL1 can serve as an in vivo marker of genetically impaired SORL1.

Variable stars in the globular cluster M28 (NGC 6626)

, 2012
We present a new search for variable stars in the Galactic globular cluster M28 (NGC 6626). The search is based on a series of BVI images obtained with the SMARTS Consortium's 1.3m telescope at Cerro Tololo Inter-American Observatory, Chile.

Deadbeat Robust Model Predictive Control: Robustness Without Computing Robust Invariant Sets

International Journal of Robust and Nonlinear Control, Volume 36, Issue 1, Page 428-438, 10 January 2026.
ABSTRACT Deadbeat Robust Model Predictive Control (DRMPC) is introduced as a new approach of Robust Model Predictive Control (RMPC) for linear systems with additive disturbances. Its main idea is to completely extinguish the effect of the disturbances in the predictions within a small number of time steps, called the deadbeat horizon.

Stability analysis of LPV systems: Scenario approach [PDF]

Automatica, 2019
[EN] This paper discusses a `scenario¿ approach to prove decay-rate stability of discrete-time polytopic linear parameter-varying systems, dealing with sets of sequences of vertex models of different length. When all sequences have the same length, parameter-trajectory dependent results in earlier literature are obtained as particular cases.

Data‐Driven Distributed Safe Control Design for Multi‐Agent Systems

International Journal of Adaptive Control and Signal Processing, Volume 40, Issue 1, Page 137-150, January 2026.
This paper presents a data‐driven control barrier function (CBF) technique for ensuring safe control of multi‐agent systems (MASs) with uncertain linear dynamics. A data‐driven quadratic programming (QP) optimization is first developed for CBF‐based safe control of single‐agent systems using a nonlinear controller. This approach is then extended to the

Structural Adaptability of IgA and IgM Supports Broad SARS‐CoV‐2 Variant Neutralization

Journal of Medical Virology, Volume 98, Issue 1, January 2026.
ABSTRACT Neutralizing emerging SARS‐CoV‐2 variants requires antibodies effective not only against epitope mutations but also under variable antigenic presentations. We assessed the neutralization capacity of the same anti‐RBD monoclonal antibody (8A5) expressed as IgG, IgA, or IgM against 18 variants, identifying three neutralization classes: variants ...

LPV/Polytopic Stabilization Control and Estimation in Robotics

Actuators
Nonlinear robotic systems often operate under widely varying conditions that challenge traditional linear control approaches. The Linear Parameter-Varying (LPV) paradigm overcomes these limitations and offers a unifying framework by representing the ...

Photometric Variability Among the Brightest Asymptotic Giant Branch Stars Near the Center of M32

, 2004
Deep K' images with 0.1 arcsec angular resolution, obtained with ALTAIR+NIRI on Gemini North, are used to investigate photometric variablity among the brightest asymptotic giant branch (AGB) stars in the central regions of M32. Based on a comparison with

An Intelligent Robust Control Framework for Stability Enhancement in Renewable Energy Powered Hybrid AC/DC Microgrids With Integrated Hydrogen Energy Systems

IET Energy Systems Integration, Volume 8, Issue 1, January/December 2026.
ABSTRACT Hybrid AC/DC microgrids that integrate photovoltaic, wind, battery and hydrogen energy systems are prone to DC‐bus voltage fluctuations because of their low inertia and converter‐based operation. This paper proposes a robust backstepping nonsingular fast terminal integral sliding mode controller that incorporates a virtual capacitor and a ...
