Structural and biochemical insights into the thermostable esterase Ta0887 from Thermoplasma acidophilum

FEBS Open Bio, EarlyView.
In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

Aging Is a Key Driver for Adult Acute Myeloid Leukemia

Aging and Cancer, EarlyView.
Acute myeloid leukemia (AML) is a classical age‐related hematologic malignancy, and a key driver of AML is aging, which profoundly regulates intrinsic factors such as genomic instability, epigenetic reprogramming, and metabolic dysregulation, and alters bone marrow microenvironment.

A Membership Agreement Algorithm Detecting and Tolerating Asymmetric Timing Faults [PDF]

, 2006
Our paper presents a new membership agreement algorithm that address asymmetric timing faults and includes a new tool simulating TTP/C clusters. The proposed algorithm flags deviating or slightly untimely messages to assure that single marginal transmitting faults are detected and that only the faulty node will be expelled. The tool can demonstrate the

Coordinated Low-Voltage Ride-Through Control of a Flywheel-Assisted Permanent-Magnet Direct-Drive Wind Power System Under Asymmetrical Grid Faults

Energies
To address fault-period DC-link overvoltage, the reduction in grid-side active-power regulation margin caused by reactive-current-priority operation, and the double-frequency current fluctuation induced by negative-sequence components under asymmetrical ...

Self‐Regulated Learning Meets AI: Reinterpreting Self‐Regulation, Co‐Regulation, and Socially Shared Regulation in Human–AI Interaction

New Directions for Adult and Continuing Education, EarlyView.
ABSTRACT Advancing artificial intelligence (AI) has transformed learning and work, yet higher education and professional development programs have not systematically equipped learners for AI‐prevalent environments. This lack of preparation creates uncertainty regarding control, responsibility, trust, and accountability.

Overcurrent Limitation and Enhanced Fault Current Utilization by Grid-Forming Inverter Using Hybrid Methods During Short Circuit Faults

IEEE Access
The next-generation grid-forming (GFM) inverters face significant over-current and over-voltage challenges during grid faults due to their inherent voltage source behaviour behind impedance. These challenges are mitigated by simultaneously reconstructing

Real-Time Discrimination of Symmetrical Faults from Power Swings [PDF]

Iranian Journal of Electrical and Electronic Engineering, 2023
For reliable operation, distance relays have to be blocked in case of stable power swings (SPSs). Because these relays are prone to detect an SPS as a symmetrical 3-phase fault according to their symmetric nature.

Multidimensional Profiling of MRI‐Negative Temporal Lobe Epilepsy Uncovers Distinct Phenotypes

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Although hippocampal sclerosis (TLE‐HS) represents the most frequent cause of temporal lobe epilepsy (TLE), up to 30% of patients show no lesion on visual MRI inspection (TLE‐MRIneg). These cases pose diagnostic and therapeutic challenges and are underrepresented in surgical series.
