A Language‐Guided Multimodal Foundation Model for Zero‐Shot and Multi‐Task Brain Signal Analysis

Advanced Intelligent Systems, EarlyView.
METIS aligns brain signals with natural‐language instructions to enable zero‐shot and multi‐task brain signal analysis. Pretrained on over 70 000 h of EEG and iEEG recordings, it generalizes across sleep stage classification, epilepsy detection, and neurological disorder diagnosis, providing a scalable foundation model for clinically meaningful brain ...

Contact Force Estimation in Human–Robot Collaboration: A Case Study on Heavyweight Robotic Manipulators

Advanced Intelligent Systems, EarlyView.
The method presented in this paper provides a practical sensorless solution for estimating both contact force and contact location using only standard joint encoders and an available robot dynamic model. By reformulating the contact estimation problem using a single scalar equivalent contact parameter, the approach enables fast and robust computation ...

Composition dependence of giant magnetoresistance in $La_{1-x}Ca_xMnO_3 (0.1\leq x\leq 0.9)$

, 1995
We have studied the resistivity $(\varrho)$ and the magnetorbistance (MR) in sintered samples of $La_{1-x}Ca_x,MnO_3$ for $0.1\leq x \leq 0.9$ in the temperature range $4.2\leq T \leq 400K$ in magnetic fields $H\leq 6T$.

A note on the well-posedness of the nonlocal boundary value problem for elliptic-parabolic equations

Electronic Journal of Qualitative Theory of Differential Equations, 2011
The abstract nonlocal boundary value problem \begin{equation*}\left\{\begin{array}{l} -\frac{d^{2}u(t)}{dt^{2}}+sign(t)Au(t)=g(t),(0\leq t\leq 1), \\ \frac{du(t)}{dt}+sign(t)Au(t)=f(t),(-1\leq t\leq 0), \\ u(1)=u(-1)+\mu \end{array}\right.\end{equation*}

Zero-sound in nuclear matter with the asymmetry parameter $-1\leq β\leq 1$

, 2018
Results for the frequencies of zero-sound excitations in the isospin asymmetric nuclear matter are presented for the different parameters of asymmetry -1\leqβ\leq 1. The dispersion equations are constructed within the random phase approximation. We use the effective Landau-Migdal quasiparticle interaction with the special isospin dependence of the ...

Distributed State Estimation for Mobile Robots in LiDAR Sensor Networks With Intermittent Inertial Measurements

Advanced Intelligent Systems, EarlyView.
A scalable distributed observer framework for LiDAR sensor networks is presented for robust tracking and pose estimation of mobile robots. By combining adaptable 3D detection, clustering‐based communication reduction, and intermittent inertial fusion, accurate and efficient estimation is achieved under occlusions and sensing constraints, with formally ...

ON WIDTHS OF SOME CLASSES OF ANALYTIC FUNCTIONS IN A CIRCLE

Ural Mathematical Journal
We calculate exact values of some $n$-widths of the class \(W_{q}^{(r)}(\Phi),\) \(r\in\mathbb{Z}_{+},\) in the Banach spaces \(\mathscr{L}_{q,\gamma}\) and \(B_{q,\gamma},\) \(1\leq q\leq\infty,\) with a weight \(\gamma\).
