Fast and stable contour integration for high order divided differences via elliptic functions [PDF]

open access: yes, 2015
In this paper, we will present a new method for evaluating high order divided differences for certain classes of analytic, possibly, operator valued functions.

Class IIa HDACs forced degradation allows resensitization of oxaliplatin‐resistant FBXW7‐mutated colorectal cancer

open access: yesMolecular Oncology, EarlyView.
HDAC4 is degraded by the E3 ligase FBXW7. In colorectal cancer, FBXW7 mutations prevent HDAC4 degradation, leading to oxaliplatin resistance. Forced degradation of HDAC4 using a PROTAC compound restores drug sensitivity by resetting the super‐enhancer landscape, reprogramming the epigenetic state of FBXW7‐mutated cells to resemble oxaliplatin ...

Accuracy Examination of the Fourier Series Approximation for Almost Limiting Gravity Waves on Deep Water

open access: yesMathematical and Computational Applications
A permanent gravity wave propagating on deep water is a classic mathematical problem. However, the Fourier series approximation (FSA) based on the physical plane was examined to be valid for almost waves at all depths.

In vitro models of cancer‐associated fibroblast heterogeneity uncover subtype‐specific effects of CRISPR perturbations

open access: yesMolecular Oncology, EarlyView.
Development of therapies targeting cancer‐associated fibroblasts (CAFs) necessitates preclinical model systems that faithfully represent CAF–tumor biology. We established an in vitro coculture system of patient‐derived pancreatic CAFs and tumor cell lines and demonstrated its recapitulation of primary CAF–tumor biology with single‐cell transcriptomics ...

Electron localization : band-by-band decomposition, and application to oxides

open access: yes, 2002
Using a plane wave pseudopotential approach to density functional theory we investigate the electron localization length in various oxides. For this purpose, we first set up a theory of the band-by-band decomposition of this quantity, more complex than ...

On the condition number of some gram matrices arising from least squares approximation in the complex plane [PDF]

open access: yesNumerische Mathematik, 1986
This paper is concerned with the condition numbers of Gram matrices that arise when computing least square polynomials in polygons of the complex plane. For a stability reason, instead of the power basis \(\{1,\lambda,\lambda^ 2,...,\lambda^ n\}\), polynomials are expressed on the basis of Chebyshev polynomials of the first kind.

Dynamics of inequalities in geometric function theory

open access: yesJournal of Inequalities and Applications, 2001
A domain in the complex plane which is star-like with respect to a boundary point can be approximated by domains which are star-like with respect to interior points. This approximation process can be viewed dynamically as an evolution of the null points

Dielectric functions of thermal electrons polarization of dry atmosphere (up to the heights plane of 12 km)

open access: yesГеофизический журнал, 2014
Spatial dispersion of complex dielectric permeability e = e + ih of a subsystem of thermal electrons and ions of standard dry atmosphere in approximation of average self-consistent electric field based on the right part of sh-Poisson equation is ...

Molecular characterisation of human penile carcinoma and generation of paired epithelial primary cell lines

open access: yesMolecular Oncology, EarlyView.
Generation of two normal and tumour (cancerous) paired human cell lines using an established tissue culture technique and their characterisation is described. Cell lines were characterised at cellular, protein, chromosome and gene expression levels and for HPV status.

A Two-Stage Numerical Algorithm for the Simultaneous Extraction of All Zeros of Meromorphic Functions

open access: yesAppliedMath
In this paper, we present an effective two-stage numerical algorithm for the simultaneous finding of all roots of meromorphic functions in a region within the complex plane. At the first stage, we construct a polynomial with the same roots as the ones of
