Loop Calculus for Non-Binary Alphabets using Concepts from Information Geometry [PDF]

, 2014
The Bethe approximation is a well-known approximation of the partition function used in statistical physics. Recently, an equality relating the partition function and its Bethe approximation was obtained for graphical models with binary variables by ...

Universal approximation by regular weighted means [PDF]

Pacific Journal of Mathematics, 1985
In this paper we shall improve upon the results by \textit{K. Faulstich}, \textit{W. Luh} and \textit{L. Tomm} [Manuscr. Math. 36, 309-321 (1981; Zbl 0479.30023)] by (i) considering power series representing other meromorphic functions f, (ii) using a regular weighted means method D to obtain the overconvergence property and (iii) showing that D has a ...

Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

Molecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...

Improved Combinatorial Approximations for Weighted Correlation Clustering [PDF]

Discrete Mathematics & Theoretical Computer Science
We present combinatorial approximation algorithms for the weighted correlation clustering problem. In this problem, we have a set of vertices and two weight values for each pair of vertices, denoting their difference and similarity.

Higher order Kantorovich-type Szász–Mirakjan operators

Journal of Inequalities and Applications, 2022
In this paper, we define new higher order Kantorovich-type Szász–Mirakjan operators, we give some approximation properties of these operators in terms of various moduli of continuity. We prove a local approximation theorem, a Korovkin-type theorem, and a

PARP inhibition and pharmacological ascorbate demonstrate synergy in castration‐resistant prostate cancer

Molecular Oncology, EarlyView.
Pharmacologic ascorbate (vitamin C) increases ROS, disrupts cellular metabolism, and induces DNA damage in CRPC cells. These effects sensitize tumors to PARP inhibition, producing synergistic growth suppression with olaparib in vitro and significantly delayed tumor progression in vivo. Pyruvate rescue confirms ROS‐dependent activity.

Approximation Properties of Certain Summation Integral Type Operators

Demonstratio Mathematica, 2015
In the present paper, we study approximation properties of a family of linear positive operators and establish direct results, asymptotic formula, rate of convergence, weighted approximation theorem, inverse theorem and better approximation for this ...

On approximation properties of a new construction of Baskakov operators

Advances in Difference Equations, 2021
The purpose of this research is to construct sequences of Baskakov operators such that their construction consists of a function σ by use of two function sequences, ξ n $\xi _{n} $ and η n $\eta _{n} $ .
