Performance change detection and recovery in inferential control loops

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract In most industrial environments, soft sensors are crucial for estimating variables that are hard to measure. It is critical that these variables be estimated quickly and accurately because they are closely linked to plant safety and profit. Therefore, performance drift in the soft sensors cannot be ignored.

Experimental methods in chemical engineering: Magnetometry

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Magnetometry is a non‐invasive technique to characterize the behaviour of magnetic materials of which the most common contain Fe, Co, and Ni. Vibrating sample magnetometers (VSMs) vibrate samples at a fixed frequency in a static, homogeneous magnetic field to induce a voltage in pick up coils according to Faraday's law of induction.

An Ultra‐Low‐Power Biopotential Acquisition Analog Front‐End Chip for Wearable Devices

open access: yesInternational Journal of Circuit Theory and Applications, EarlyView.
A 0.8‐V, 1.2‐μW biopotential AFE combines a chopper‐stabilized CCIA with dual‐time‐scale EDO management. The slow DSL preserves > 1 GΩ input impedance, whereas an event‐triggered fast‐recovery path shortens return to the linear range after abrupt electrode‐offset disturbances. ABSTRACT A 0.8‐V, 1.2‐μW biopotential analog front‐end (AFE) IC is presented

Power allocation in NOMA with decoding order error of successive interference cancellation [PDF]

open access: yesIranian Journal of Electrical and Electronic Engineering
In this paper, the decoding order error of successive interference cancellation (SIC) of multicarrier nonorthogonal multiple access (NOMA) due to the random walk of the users and position estimation deviation is considered in resource allocation.

Extended routine lymphocyte immunophenotyping refines individual immune organization across a heterogeneous patient cohort

open access: yesCytometry Part B: Clinical Cytometry, EarlyView.
Abstract Routine TBNK immunophenotyping detects the major lymphocyte compartments but may underestimate the biologically relevant variation contributed by less frequent but well‐defined minor lymphocyte subsets. This study evaluated whether extending routine TBNK immunophenotyping with minor lymphocyte subsets provides complementary, analytically ...

Micro‐QuEChERS Extraction for Broad‐Spectrum LC‐QQQ‐MS Quantification of Nitazene Analogs in Plasma: A Validated Method With Casework Application

open access: yesDrug Testing and Analysis, EarlyView.
Micro‐QuEChERS sample preparation coupled to LC‐QQQ‐MS enabled sensitive quantification of nitazene analogs in 100 μL of plasma. The validated method provided low detection limits and was successfully applied to an authentic intoxication case involving N‐pyrrolidino protonitazene, supporting clinical and forensic toxicology workflows.

Water Governance Under International Pressure: Policy Narratives, Food Security, Scarcity, and the Politics of Survival in Iran

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT Water governance is increasingly influenced by a paradox at the nexus of environmental scarcity and food security. Escalating water scarcity crises coincide with geopolitical disruptions that have exposed the fragility of global food supply chains, prompting states to expand domestic food production at the expense of water conservation ...

Semaglutide normalizes increased cardiomyocyte calcium transients in a rat model of high fat diet‐induced obesity

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1386-1397, April 2025.
Sequeira et al. reveal how the glucagon‐like peptide‐1 receptor agonist (GLP‐1‐RA) semaglutide restores cardiomyocyte function in rats subjected to a high‐fat/high‐fructose diet (HFD). Employing fluorescence‐ and patch‐clamp technology in isolated cardiac myocytes, they demonstrate that semaglutide reverses HFD‐induced activation of L‐type calcium ...
