Analytically approximation solution to Einstein-Cubic gravity

European Physical Journal C: Particles and Fields, 2022
In this work, we introduce analytical approximate black hole solutions in Einstein-Cubic gravity. To obtain complete solutions, we construct the near horizon and asymptotic solutions as the first step.

Fast parallel calculation of modified Bessel function of the second kind and its derivatives

SoftwareX, 2022
There are three main types of numerical computations for the Bessel function of the second kind: series expansion, continued fraction, and asymptotic expansion. In addition, they are combined in the appropriate domain for each.

Colorectal cancer‐derived FGF19 is a metabolically active serum biomarker that exerts enteroendocrine effects on mouse liver

Molecular Oncology, EarlyView.
Meta‐transcriptome analysis identified FGF19 as a peptide enteroendocrine hormone associated with colorectal cancer prognosis. In vivo xenograft models showed release of FGF19 into the blood at levels that correlated with tumor volumes. Tumoral‐FGF19 altered murine liver metabolism through FGFR4, thereby reducing bile acid synthesis and increasing ...

A Simple Numerical Method for Stability Testing of a Certain Class of Linear Half-Order Systems

IEEE Access
This paper focuses on a particular subclass of fractional-order systems, namely linear half-order systems. It is now well established that the half-order derivative of a potential has a direct physical interpretation as a flux. Consequently, such systems

A Gauss-Kuzmin Theorem for Continued Fractions Associated with Nonpositive Integer Powers of an Integer m≥2

The Scientific World Journal, 2014
We consider a family {τm:m≥2} of interval maps which are generalizations of the Gauss transformation. For the continued fraction expansion arising from τm, we solve a Gauss-Kuzmin-type problem.

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

Molecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

Viscovatov-Like Algorithm of Thiele–Newton’s Blending Expansion for a Bivariate Function

Mathematics, 2019
In this paper, Thiele−Newton’s blending expansion of a bivariate function is firstly suggested by means of combining Thiele’s continued fraction in one variable with Taylor’s polynomial expansion in another variable.

Synthesis by continued-fraction expansion

Electronics Letters, 1971
A sufficient relationship between the even part of the numerator polynomial and the odd part of the denominator polynomial is proved for a class of positive real (p.r.) rational functions, to be realisable as an RLC immittance by the continued-fraction expansion technique.

Pre‐analytical optimization of cell‐free DNA and extracellular vesicle‐derived DNA for mutation detection in liquid biopsies

Molecular Oncology, EarlyView.
Pre‐analytical handling critically determines liquid biopsy performance. This study defines practical best‐practice conditions for cell‐free DNA (cfDNA) and extracellular vesicle–derived DNA (evDNA), showing how processing time, storage conditions, tube type, and plasma input volume affect DNA integrity and mutation detection.
