Lyapunov function search method for analysis of nonlinear systems stability using genetic algorithm
A wide class of smooth continuous dynamic nonlinear systems (control objects) with a measurable state vector is considered. The problem of finding a special function (Lyapunov function), which guarantees asymptotic stability for the presented class of ...

The roots of a polynomial depend continuously on its coefficients
The paper contains an elementary proof of the continuous dependence of the roots of a complex polynomial on its coefficients. The proof uses some inequalities involving the coefficients of a complex polynomial.

Evolution‐guided yeast complementation reveals functional differences in human PSPH variants
Ancient genomes can help guide which human genetic variants are tested experimentally. This study applies that idea to PSPH, a gene involved in serine biosynthesis, and uses high‐throughput yeast complementation to compare variant function. The findings reveal measurable differences among selected alleles and illustrate the value of evolution‐guided ...

Continuous dependence on the coefficients for a class of non-autonomous evolutionary equations
38 pages, I changed the introduction and included some more references. Moreover, I added a new section illustrating the results obtained by an equation of mixed type. Slightly rearranged the content. More details in some proofs.

Long‐Term Follow‐Up of Chemotherapy‐Associated Biological Aging in Women With Early Breast Cancer
Women threated with adjuvant chemotherapy for early breast cancer have sustained long‐term increase in p16INK4a,, a robust marker of cell senescence, suggesting a chemotherapy‐associated age acceleration. p16INK4a as well as other biomarkers may identify patients at greatest risk for senescence‐related diseases of aging.

Developmental and Epileptic Encephalopathy due to Biallelic Pathogenic Variants in PIGM
ABSTRACT Objective PIGM encodes a critical enzyme in the glycosylphosphatidylinositol (GPI)‐anchor biosynthesis pathway. While promoter‐region mutations in PIGM have been associated with a relatively mild phenotype characterized by portal vein thrombosis and absence seizures, recent evidence suggests that coding‐region mutations result in a more severe

Location‐Specific Hematoma Volume Predicts Early Neurological Deterioration in Supratentorial ICH
ABSTRACT Objective Early neurological deterioration (END) adversely affects outcomes in patients with intracerebral hemorrhage (ICH). This study aimed to determine the location‐specific hematoma volumes for END in supratentorial ICH patients. Methods We retrospectively analyzed supratentorial ICH patients presenting from two prospective cohorts.

Energy scaling of energetic particle transport by microturbulence
Energetic particle (EP) transport induced by the microturbulence are studied both theoretically and numerically. Based on the quasi-linear theory, the expressions of the four diffusion coefficients describing the EP transport in radial-velocity space ( r
