Analytical evaluation of beam deformation problem using approximate methods [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2010
The beam deformation equation has very wide applications in structural engineering. As a differential equation, it has itsown problem concerning existence, uniqueness and methods of solutions. Often, original forms of governing differentialequations used

On optimizing the treatment of exchange perturbations [PDF]

A method using the zeroth plus first order wave functions, obtained by optimizing the basic equation used in exchange perturbation treatments, is utilized in an attempt to determine the exact energy and wave function in the exchange process.

Conserved cosmological perturbation in Galileon models

, 2011
We prove the existence of a fully nonlinear conserved curvature perturbation on large scales in Galileon-type scalar field models in two approaches. The first approach is based on the conservation of energy-momentum tensor of the Galileon field, which is

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

Posterior Cortical Atrophy in the Asia‐Pacific: A Report From the PCA Asian Workgroup

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Posterior Cortical Atrophy (PCA) is a distinct dementia syndrome primarily affecting spatial abilities and visual processing. It is associated with degeneration in the posterior part of the brain. PCA is subclassified into PCA‐pure and PCA‐plus syndromes based on consensus criteria.

Propagation characteristics and damage detection in metallic materials using nonlinear acoustic waves

AIP Advances
The propagation properties of nonlinear acoustic waves are of paramount importance for detecting damage in metallic materials. Currently, the perturbation method, expanded with respect to the nonlinear coefficient, is a prevalent approach for solving the

Second order parameter-uniform convergence for a finite difference method for a singularly perturbed linear reaction-diffusion system [PDF]

, 2010
A singularly perturbed linear system of second order ordinary differential equations of reaction-diffusion type with given boundary conditions is considered. The leading term of each equation is multiplied by a small positive parameter.

RNA Sequencing Resolves Cryptic Pathogenic Variants in Mitochondrial Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Mitochondrial diseases are the most common inherited metabolic disorders, characterized by pronounced clinical and genetic heterogeneity that complicates molecular diagnosis. Although DNA‐based sequencing approaches have become standard in genetic testing, up to half of patients remain without a definitive diagnosis.
