Stability Analysis of a Receiving-End VSC-HVDC System with Parallel-Connected VSCs

Electronics
Voltage source converter-based high-voltage direct current (VSC-HVDC) systems integrated into weak AC grids may exhibit oscillation-induced instability, posing significant threats to power system security. With increasing structural complexity and diverse control strategies, the stability characteristics of VSC-HVDC system require further investigation.

A Novel Peak‐Shape Aware Approach for Mass Alignment in Mass Spectrometry

Rapid Communications in Mass Spectrometry, Volume 40, Issue 4, 28 February 2026.
ABSTRACT Rationale In mass spectrometry measurements, mass shifts may be inadvertently introduced due to instrumental drift and calibration inaccuracies, potentially compromising the accuracy of subsequent data analysis. This work presents a novel, label‐free algorithm to improve relative mass alignment between mass spectra.

On the behavior of geodesics of left-invariant sub-Riemannian metrics on the group $ \operatorname{Aff}_{0}(\mathbb{R}) \times \operatorname{Aff}_{0}(\mathbb{R}) $

Electronic Research Archive
In this paper, we study geodesics of left-invariant sub-Riemannian metrics on the Cartesian square of a connected two-dimensional non-commutative Lie group, where the metric is determined by the inner product on a two-dimensional generating subspace of ...

Timing of Secondary Palate Fusion in Human Embryos and Fetuses

Birth Defects Research, Volume 118, Issue 2, February 2026.
ABSTRACT Introduction The human face develops through a complex sequence of growth and fusion events involving multiple pharyngeal arch derivatives. Disruptions in these processes can result in congenital anomalies such as cleft lip and/or palate (CL/P), which occur in approximately 1.6 per 1000 live births in Europe.

A Statistical Shape Modeling Approach for the Derivation of a Data‐Driven Geometry‐Aware Lumped Arterial Stenosis Model

International Journal for Numerical Methods in Biomedical Engineering, Volume 42, Issue 2, February 2026.
A data‐driven workflow for constructing a geometry‐aware lumped arterial stenosis model: Statistical shape modeling extracts geometry‐specific shape modes from synthetically generated coronary lesion geometries. Large‐scale 3D CFD simulations over varying Reynolds numbers yield the geometries their viscous (Kv) and inertial (Kt) loss coefficients. Then,

Astrocyte Senescence Impairs Synaptogenesis due to Thrombospondin‐1 Loss

Aging Cell, Volume 25, Issue 2, February 2026.
Senescent hippocampal astrocytes lose TSP secretion, impairing excitatory synaptogenesis via the α2δ‐1 pathway. Restoring TSP‐1 rescues synaptic formation, revealing the contribution of astrocyte senescence to age‐related hippocampal synaptic decline.
