Global Stabilization of Nonlinear Networked Control System with System Delays and Packet Dropouts via Dynamic Output Feedback Controller

open access: yesMathematical Problems in Engineering, Volume 2015, Issue 1, 2015., 2015
The stabilization problem is investigated for a class of nonlinear discrete‐time networked control systems (NCSs). Nonideal network Quality of Services (QoS) are considered, more specifically data packet dropouts and network‐induced delays. A state feedback controller for a class of NCSs is proposed.

On X‐valued sequence spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 20, Issue 1, Page 47-50, 1997., 1995
Certain spaces of X‐valued sequences are introduced and some of their properties are investigated. Köthe‐ Toeplitz duals of these spaces are examined.

Acute Supplementation of Beta‐Hydroxybutyrate Increases Visual Cortical Excitability in Humans: A Combined Electro‐EncephaloGraphy and Magnetic Resonance Spectroscopy Study

open access: yesEuropean Journal of Neuroscience, Volume 62, Issue 7, October 2025.
Elevated plasma β‐hydroxybutyrate levels achieved by acute supplementation increased occipital glutamate (but not GABA+) levels and enhanced visual cortical excitability, as measured by larger steady‐state visual evoked potentials. The glutamate increase correlated with the increased steady‐state visual evoked potentials amplitude.

An application of the Sakai′s theorem to the characterization of H*‐algebras

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 18, Issue 2, Page 317-322, 1995., 1995
The well‐known Sakai′s theorem, which states that every derivation acting on a von Neumann algebra is inner, is ,used to obtain a new elegant proof of the Saworotnow′s characterization theorem for associative H*‐algebras via two‐sided H*‐algebras. This proof completely avoids structure theory.

Facile Solid‐State Synthesis of Prelithiated LiTiO2 With Nitrogen‐Doped Carbon for Lithium‐Ion Battery Anodes

open access: yesInternational Journal of Energy Research, Volume 2025, Issue 1, 2025.
Although Ti‐based oxides are attractive anode materials for Li‐ion batteries (LIBs) owing to their inherent stability and enhanced safety, their electrochemical performance is severely limited by low conductivity and slow Li‐ion diffusion. Conventional LiTiO2 synthesis methods are not cost‐effective because they rely on high‐purity precursors and ...

Some absolutely effective product methods

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 15, Issue 4, Page 641-651, 1992., 1992
It is proved that the product method A(C, 1), where (C, 1) is the Cesàro arithmetic mean matrix, is totally effective under certain conditions concerning the matrix A. This general result is applied to study absolute Nörlund summability of Fourier series and other related series.

Redesigning mineral regimes to strengthen the environmental rule of law: A case study on lithium in brines

open access: yesReview of European, Comparative &International Environmental Law, Volume 33, Issue 3, Page 633-646, November 2024.
Abstract This article aims to contribute to aligning the legal regimes for energy transition minerals with sustainability and justice. The focus of the article is on effectively embedding the human right to a healthy environment into the design of these regimes.

Chiral Recognition: A Spin‐Driven Process in Chiral Oligothiophene. A Chiral‐Induced Spin Selectivity (CISS) Effect Manifestation

open access: yesAdvanced Functional Materials, Volume 34, Issue 2, January 9, 2024.
It is demonstrated that probing the handedness of a chiral system (here a chiral‐electrode‐surface/solution interface) by using a spin‐polarized current, allows for chiral recognition. This conclusion is inferred by tight comparison with cyclic voltammetry results, where the handedness of the “chiral‐electrode‐surface/solution interface” is recognized ...

Intoxicación por Litio

open access: yesREV SEN, 2023
Introducción: El litio es el tratamiento de elección para el trastorno afectivo bipolar. Uno de sus inconvenientes es su estrecho índice terapéutico y las complicaciones asociadas a las concentraciones supraterapéuticas. La sospecha clínica, las manifestaciones clínicas y la medición de los niveles de litio son esenciales para el diagnóstico.
