Two different interictal spike patterns anticipate ictal activity in vitro

open access: yesNeurobiology of Disease, 2013
4-Aminopyridine (4AP, 50 μM) induces interictal- and ictal-like discharges in brain slices including parahippocampal areas such as the entorhinal cortex (EC) but the relation between these two types of epileptiform activity remains undifined.

Performance improvement of discrete‐time linear‐quadratic regulators applied to uncertain linear systems using the Tikhonov regularization method

open access: yesAsian Journal of Control, EarlyView.
Abstract The linear‐quadratic regulator (LQR) problem of optimal control of an uncertain discrete‐time linear system (DTLS) is revisited in this paper from the perspective of Tikhonov regularization. We show that an optimally chosen regularization parameter reduces, compared to the classical LQR, the values of a scalar error function, as well as the ...

Prosumers and Sustainable Market Governance: Development of the Community‐Oriented Marketing Approach Scale

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This research develops and empirically validates the Community‐Oriented Marketing Approach (COMA), a 20‐item multidimensional scale designed to measure prosumer perceptions within participatory market systems. COMA conceptualizes prosumers as active co‐value creators and institutional agents, driving sustainable market governance.

The Successful Treatment of High Lethal Dose Paraquat Poisoning With Hemoperfusion

open access: yesInternational Journal of Medical Toxicology and Forensic Medicine, 2020
Paraquat (PQ), as an herbicide, is mostly used by farmers, especially in the north-west of Iran. Easy access to PQ is the reason for PQ intoxication in farm­ers. However, poisoning with PQ is rare.

The Synthesis Effects on the Performance of P2‐Na0.6Li0.27Mn0.73O2 Cathode Material for Sodium‐Ion Batteries

open access: yesBattery Energy, Volume 4, Issue 2, March 2025.
The effect of reagents on the structure and performance of sodium‐layered oxides has not yet been thoroughly studied. This work explored this factor systematically through in situ high‐temperature XRD. The samples synthesized via MnCO3‐based precursors form the Li2MnO3 phase at evaluated temperature and perform better than those through MnO2‐based ...

Donor‐To‐Recipient Mean Axonal Count Ratios of Upper Limb Nerves Used in Nerve Transfer Surgery: A Systematic Review of Histomorphometric Cadaveric Studies

open access: yesClinical Anatomy, EarlyView.
ABSTRACT Nerve transfer surgery may be performed to restore sensorimotor function following peripheral nerve trauma or dysfunction. There is biological plausibility and limited correlative evidence that donor‐to‐recipient axon count ratios may impact functional outcomes.

On pq-hyperelliptic Riemann surfaces [PDF]

open access: yesColloquium Mathematicum, 2005
Let \(X\) be a compact Riemann surface of genus \(g\geq 2\). The surface \(X\) is said to be \(p\)-hyperelliptic if it admits a conformal involution \(\rho \), called a \(p\)-hyperelliptic involution, such that the quotient \(X/\rho \) has genus \(p\). Let us suppose that \(X\) also admits a \(q\)-hyperelliptic involution.
