Evaporative cooling by pulse width modulation (PWM) of optical dipole traps

Physical Review Research
We introduce a method for cooling atoms in an optical dipole trap using pulse-width modulation (PWM) technique, without reducing the laser power of the dipole trap. The PWM technique involves digital modulation of the trap at a fixed frequency.

TOP1MT rs2293925 is an enhancer‐active regulatory SNP that shapes mitochondrial R‐loop dynamics

The FEBS Journal, EarlyView.
This study shows how a common genetic variant of mitochondrial topoisomerase 1 (TOP1MT rs2293925) can influence mitochondrial gene regulation, DNA topology, and formation of noncanonical nucleic acid structures such as R‐loops. By linking this enhancer‐active variant to mitochondrial nucleic acid stress in cellular contexts relevant to amyotrophic ...

A novel and easy‐to‐implement modulation scheme for reducing modulation complexity in modular multilevel converter

IET Power Electronics
Modulation strategy plays a key role in the operation of modular multilevel converters (MMC). Although many studies have been carried out on its optimization in MMC, the limitations of hardware implementation are seldom considered.

UC2‐ESP: A general‐purpose framework for open‐source microscopy control

Journal of Microscopy, EarlyView.
Abstract Building the optical setup for investigating biological questions comes with challenges. A major such challenge is setting up and synchronizing the control of multiple hardware components such as stages, cameras and lasers. With UC2‐ESP, we present a low‐cost electronics system powered by the ESP32 microcontroller (∼$10), designed as an ...

A Capacitor Voltage Balancing Hybrid PWM Technique to Improve the Performance of T-Type NPC Inverters

IEEE Access
Research into solar photovoltaic (PV) fed grid-tied multilevel inverters (MLIs) has increased in recent years due to their distinct features compared to two-level voltage source inverters (VSIs).

Neural correlates of pure apathy in multiple sclerosis: An exploratory neuroimaging study

Journal of Neuropsychology, EarlyView.
Abstract Pure apathy is relatively common in people with Multiple Sclerosis (PwMS), but its neural mechanisms remain unexplored. Therefore, we investigated the neural correlates of pure apathy in PwMS, differentiating it from depression. Sixty‐two PwMS underwent neuropsychological assessments and Magnetic Resonance Imaging scans.

Preservation of positive emotion recognition in patients with multiple sclerosis: Artefact related to methodological issues or real feature of the disorder?

Journal of Neuropsychology, EarlyView.
Abstract Prior studies in multiple sclerosis (MS) suggest preserved recognition of positive emotions despite deficits for negative ones, but this dissociation may reflect methodological limitations (valence‐asymmetry: positive‐valence being limited to happiness/joy in basic‐emotion sets). This study tested whether emotion–recognition deficits in MS are

Ageing alters cysteine oxidation‐regulated redox signalling in skeletal muscle: Integrative omics and AI‐based structural predictions

Experimental Physiology, EarlyView.
Abstract Ageing is associated with loss of skeletal muscle mass and strength (sarcopenia) and disrupted redox homeostasis. Redox signalling is essential for muscle adaptation, yet the mechanisms by which ageing disrupts cysteine‐based regulation are poorly defined. The drivers of site‐specific reactivity and signalling specificity in aged muscle remain

Sex‐Modulated TACSTD2 Methylation and Hormone‐Receptor Axis Interactions in Glioblastoma: Insights Toward Mechanistic Understanding

Computational and Systems Oncology, Volume 6, Issue 1, December 2026.
Sex‐stratified analyses of the TCGA and CGGA cohorts have identified promoter‐proximal TACSTD2 CpG sites where methylation shows opposite survival associations in males and females, is independent of copy number, and correlates with TACSTD2 expression.

Enhancing Reference Tracking in Induction Motor Drives: A Hybrid Model Predictive Control and Artificial Neural Network Approach

International Journal of Robust and Nonlinear Control, Volume 36, Issue 14, Page 6719-6738, 25 September 2026.
ABSTRACT Induction motors (IMs) are widely used in industry for their robustness and cost‐effectiveness, yet their nonlinear and multivariable dynamics pose significant challenges for high‐performance speed control. Model Predictive Control (MPC) is a well‐established solution but suffers from limitations related to model accuracy and parameter ...
