On the Accuracy of the Exponential Approximation to Random Sums of Alternating Random Variables

Mathematics, 2020
Using the generalized stationary renewal distribution (also called the equilibrium transform) for arbitrary distributions with a finite non-zero first moment, we prove moment-type error-bounds in the Kantorovich distance for the exponential approximation

Implicit parameter estimation for conditional Gaussian Bayesian networks [PDF]

International Journal of Computational Intelligence Systems, 2014
The Bayesian estimation of the conditional Gaussian parameter needs to define several a priori parameters. The proposed approach is free from this definition of priors.

A closed-form formula for the conditional expectation of the extended CIR process [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2020
This paper is an extension to a recent paper by Rujivan (2016), in which we derive a closed-form formula for the conditional expectation of the valuation process, defined by         , :        T s t t r s ds r u du T t T T s t

Reduced vascular leakage correlates with breast carcinoma T regulatory cell infiltration but not with metastatic propensity

Molecular Oncology, EarlyView.
A mouse model for vascular normalization and a human breast cancer cohort were studied to understand the relationship between vascular leakage and tumor immune suppression. For this, endothelial and immune cell RNAseq, staining for vascular function, and immune cell profiling were employed.

Looking Backward and Looking Forward

Econometrics, 2019
Filtering has had a profound impact as a device of perceiving information and deriving agent expectations in dynamic economic models. For an abstract economic system, this paper shows that the foundation of applying the filtering method corresponds to ...

An Expectation Conditional Maximization Approach for Gaussian Graphical Models [PDF]

Journal of Computational And Graphical Statistics, 2017
Bayesian graphical models are a useful tool for understanding dependence relationships among many variables, particularly in situations with external prior information.

Strength through diversity: how cancers thrive when clones cooperate

Molecular Oncology, EarlyView.
Intratumor heterogeneity can offer direct benefits to the tumor through cooperation between different clones. In this review, Kuiken et al. discuss existing evidence for clonal cooperativity to identify overarching principles, and highlight how novel technological developments could address remaining open questions.

Satellite Image Inpainting With Edge-Conditional Expectation Attention

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Satellite images often suffer from data loss and corruption due to various factors, including sensor malfunctions and atmospheric interference, leading to incomplete and degraded imagery.

Bivariate Discrete Odd Generalized Exponential Generator of Distributions for Count Data: Copula Technique, Mathematical Theory, and Applications

Axioms, 2023
In this article, a new family of bivariate discrete distributions is proposed based on the copula concept, in the so-called bivariate discrete odd generalized exponential-G family.

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 ...
