Novel Genetic Findings in Stuve‐Wiedemann Syndrome: A Case Report and Review of Literature

Clinical Case Reports, Volume 14, Issue 1, January 2026.
ABSTRACT Stuve‐Wiedemann Syndrome (SWS) is a rare autosomal recessive condition, first reported in 1971 by Stuve and Wiedemann. It is associated with pathogenic or likely pathogenic homozygous or compound heterozygous variants in the Leukemia Inhibitory Factor Receptor (LIFR) gene.

Mechanistic Understanding of Laser‐Induced Defect Engineering of Anisotropic Cobalt Oxide Spinel Platelets in Water

ChemCatChem, Volume 18, Issue 1, 15 January 2026.
Pulsed laser defect engineering in liquid (PUDEL) modifies anisotropic Co3O4 platelets by inducing lattice distortions and defects while enriching {111} surfaces with hydroxyl groups and tunes the catalytic activity of the Co3O4 platelets in electrocatalytic oxygen evolution and thermocatalytic selective oxidation reactions.

Laser‐Induced Iron Doping of Spinel Thin Film Electrocatalyst: Impact of Pulsed Laser Processing on Surface Cobalt Oxide Doping and Oxygen Evolution Reaction Activity

ChemCatChem, Volume 18, Issue 2, 28 January 2026.
Laser‐induced Fe doping of Co3O4 thin films enables pulse‐controlled, depth‐selective modification. Correlating doping profiles with SECCM maps reveals optimal OER activity at intermediate Fe levels, establishing PUDEL as a precise tool for tailoring model electrocatalyst surfaces.

Automatic analysis of Swift-XRT data

, 2007
The Swift spacecraft detects and autonomously observes ~100 Gamma Ray Bursts (GRBs) per year, ~96% of which are detected by the X-ray telescope (XRT). GRBs are accompanied by optical transients and the field of ground-based follow-up of GRBs has expanded
