Stability of the inverse resonance problem for Jacobi operators
, 2012 When the coefficients of a Jacobi operator are finitely supported perturbations of the 1 and 0 sequences, respectively, the left reflection coefficient is a rational function whose poles inside, respectively outside, the unit disk correspond to ...

Modelling of Stochastic Absorption in a Random Medium [PDF]
, 2000 We report a detailed and systematic study of wave propagation through a stochastic absorbing random medium. Stochastic absorption is modeled by introducing an attenuation constant per unit length $\alpha$ in the free propagation region of the one ...

Developmental and Epileptic Encephalopathy due to Biallelic Pathogenic Variants in PIGM
Annals of Clinical and Translational Neurology, EarlyView.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

Gravity waves as a mechanism of troposphere–stratosphere–mesosphere coupling during sudden stratospheric warming [PDF]
Atmospheric Chemistry and PhysicsThe propagation of gravity waves (GWs) and their role in the coupling of the troposphere–stratosphere–mesosphere atmospheric layers during sudden stratospheric warming (SSW) are studied. A standard set of hydrodynamic (HD) equations is used to derive the

Reconstruction of the spatial dependency of dielectric and geometrical properties of adhesively bonded structures [PDF]
, 2005 An inverse problem motivated by the nondestructive testing of adhesively bonded structures used in the aircraft industry is studied. Using transmission line theory, a model is developed which, when supplied with electrical and geometrical parameters ...

Clinical Validation of Plasma p‐217tau in Neurological Diseases
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Plasma p‐217tau is a minimally invasive but specific biomarker for diagnosing Alzheimer's disease (AD). However, its disease specificity remains to be clinically evaluated. We validated the reliability of the p‐217tau biomarker in 12 other neurological diseases.

Reflection coefficient for two elastic layers joining two homogeneous materials
Archives of Acoustics, 2015 Two homogeneous elastic layers are situated between two homogeneous elastic materials. The reflection coefficient for the harmonic wave depends on the elastic constants of the layers and the frequency.
