Long‐Term Effects of a Dietary Humic Substance–Butyrate Blend, and Yeast Cell Wall on Growth Performance, Immune Status and Gut Microbiota of Juvenile Channel Catfish Ictalurus punctatus

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.
ABSTRACT This study evaluated the long‐term effects of a dietary humic substance and butyrate blend (HSB) alone or with yeast cell wall (Beta‐MOS) in channel catfish. Around 1440 fish (31.31 ± 0.24 g) were distributed among 12 outdoor tanks in a pond‐supplied flow‐through design. Four dietary treatments were evaluated in triplicate: Diets containing no

A robust solution for PI-based LFC problem with communication delays [PDF]

open access: yes, 2005
This paper addresses a new method to design a PI-based load-frequency control (LFC) with communication delays. First the LFC problem is reduced to a static output feedback control synthesis for a multiple delays system, and then the control parameters ...

Covert Attack in Load Frequency Control of Power Systems [PDF]

open access: yes, 2020
The purpose of this work is to design a covert agent structure that can create a non-zero frequency deviation in the load frequency control (LFC) system and illustrate the necessity of a secure communication network for the load frequency control.

Mechanistic Insights and Performance Advancements in Flow Capacitive Deionisation for Sustainable Energy Conversion

open access: yesElectrochemical Science Advances, Volume 6, Issue 4, August 2026.
ABSTRACT Flow capacitive deionisation is an advanced electrochemical technology for water purification and energy‐related applications. It represents a viable alternative to conventional desalination methods due to its low operating voltage, continuous electrode regeneration, and stable performance under moderate‐to‐high salinity conditions. The use of

Measurable residual disease by multicolor flow cytometry in acute myeloid leukemia: A comparison of peripheral blood and bone marrow

open access: yesCytometry Part B: Clinical Cytometry, Volume 110, Issue 4, Page 259-265, July 2026.
Abstract Measurable residual disease (MRD) monitoring by multiparameter flow cytometry (MFC) is well established in bone marrow (BM) samples for acute myeloid leukemia (AML), but its use in peripheral blood (PB) remains less developed. We adapted a semi‐automated and well validated MFC‐MRD assay, originally developed for BM, to PB aiming to evaluate ...

An Investigation of Coordinated Attack on Load Frequency Control

open access: yesIEEE Access, 2018
In this paper, optimal attack schemes against load frequency control (LFC) are studied by considering coordinated attack. By attacking sensor measurement (load) simultaneously, the attacker disrupts the normal operation of LFC, thus causing excess system
