Scaling the Dynamic Buckling Behavior of a Box Girder Based on the Finite Similitude Approach

Journal of Marine Science and Engineering
In the design of small-scale test models for hull structures, the directional dimensional analysis method is commonly employed. However, conventional dimensional analysis based on elasticity theory may be insufficient to capture the nonlinear behaviors ...

A scalar transport equation [PDF]

Transactions of the American Mathematical Society, 1957
Here the variables x, y, t are non-negative, and the functions f(x, 0), 4(x, y) and #1(x, y) are assumed to be known. The main result (Theorem 1) is that under certain hypotheses on f(x, 0), 4(x, y) and yG(x, y) there exists a continuous solution f(x, t), valid for x, t_ 0, which is non-negative, analytic in t for each x, and integrable in x for each f.

Cerebrospinal Fluid Liquid Biopsy Enables Targeted Therapy Without Tissue Diagnosis in Pediatric Low‐Grade Gliomas With BRAF V600E Mutation

Pediatric Blood &Cancer, EarlyView.
ABSTRACT We present two pediatric cases of pediatric low‐grade gliomas (PLGG) with BRAF V600E mutations diagnosed and monitored using cerebrospinal fluid (CSF) liquid biopsy analyzed via digital droplet PCR (ddPCR), without tissue biopsy. Both patients were treated with dabrafenib and trametinib and monitored through clinical assessments, magnetic ...

Relationship of Transport Coefficients with Statistical Quantities of Charged Particles

The Astrophysical Journal, 2023
In previous studies, a general spatial transport equation was derived from the Fokker–Planck equation. The latter equation contains an infinite number of spatial derivative terms T _n = κ _nz ∂ ^n F /∂ z ^n with n = 1, 2, 3, ⋯ .

Physical Pictures of Transport in Heterogeneous Media: Advection-Dispersion, Random Walk and Fractional Derivative Formulations

, 2002
The basic conceptual picture and theoretical basis for development of transport equations in porous media are examined. The general form of the governing equations is derived for conservative chemical transport in heterogeneous geological formations, for

TRANSPORT EQUATIONS FROM LIOUVILLE EQUATIONS FOR FRACTIONAL SYSTEMS [PDF]

International Journal of Modern Physics B, 2006
We consider dynamical systems that are described by fractional power of coordinates and momenta. The fractional powers can be considered as a convenient way to describe systems in the fractional dimension space. For the usual space the fractional systems are non-Hamiltonian.

A Comparative Study of Cerebral Oxygenation During Exercise in Hemodialysis and Peritoneal Dialysis Patients

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Cognitive impairment and exercise intolerance are common in dialysis patients. Cerebral perfusion and oxygenation play a major role in both cognitive function and exercise execution; HD session per se aggravates cerebral ischemia in this population. This study aimed to compare cerebral oxygenation and perfusion at rest and in mild

Stability of non-autonomous difference equations with applications to transport and wave propagation on networks

Networks and Heterogeneous Media, 2016
In this paper, we address the stability of transport systems and wave propagation on networks with time-varying parameters. We do so by reformulating these systems as non-autonomous difference equations and by providing a suitable representation of their

Phenomenological Transport Equation for the Cuprate Metals

, 1996
We observe that the appearance of two transport relaxation times in the various transport coefficients of cuprate metals may be understood in terms of scattering processes that discriminate between currents that are even, or odd under the charge ...

Singular eigenfunctions for the three-dimensional radiative transport equation. [PDF]

Journal of The Optical Society of America A-optics Image Science and Vision, 2013
Case's method obtains solutions to the radiative transport equation as superpositions of elementary solutions when the specific intensity depends on one spatial variable.
