Torsion-free covers of solvable minimax groups [PDF]

, 2015
We prove that every finitely generated solvable minimax group can be realized as a quotient of a torsion-free solvable minimax group. This result has an application to the investigation of random walks on finitely generated solvable minimax groups.

A Concave-penalized Logistic Regression Model for Predicting ICI Treatment Respense [PDF]

Zhengzhou Daxue xuebao. Gongxue ban
To improve the accuracy of predicting the response of melanoma patients to immune checkpoint inhibitor (ICI) therapy, a new method integrating bulk RNA-seq and single-cell RNA-seq data was proposed.

Favoring the hierarchical constraint in penalized survival models for randomized trials in precision medicine

BMC Bioinformatics, 2023
Background The research of biomarker-treatment interactions is commonly investigated in randomized clinical trials (RCT) for improving medicine precision. The hierarchical interaction constraint states that an interaction should only be in a model if its

Sequential Minimax Search for Multi-Layer Gene Grouping

IEEE Access, 2019
Many areas of exploratory data analysis need to deal with high-dimensional data sets. Some real life data like human gene have an inherent structure of hierarchy, which embeds multi-layer feature groups.

Accounting for grouped predictor variables or pathways in high-dimensional penalized Cox regression models

BMC Bioinformatics, 2020
Background The standard lasso penalty and its extensions are commonly used to develop a regularized regression model while selecting candidate predictor variables on a time-to-event outcome in high-dimensional data. However, these selection methods focus

Promising medium-term results of anterior approach with an anatomical short stem in primary hip arthroplasty

Journal of Orthopaedics and Traumatology, 2021
Background In the last decade, the increase in the use of the direct anterior approach to the hip has contributed to the diffusion of the use of short stems in orthopedic surgery.

Virtually torsion-free covers of minimax groups

, 2020
We prove that every finitely generated, virtually solvable minimax group can be expressed as a homomorphic image of a virtually torsion-free, virtually solvable minimax group. This result enables us to generalize a theorem of Ch. Pittet and L.

On invariant ideals in crossed products of torsion-free minimax nilpotent groups

Researches in Mathematics
Let $R$ be a finitely generated commutative domain and let $N$ be a nilpotent minimax torsion-free group acted by a solvable group of operators $G$ of finite rank.

Interleukin‐1α Mediates Pancreatic Fibroblast Activation, Regulates Immune Cell Recruitment and Fibrosis in Acute and Chronic Pancreatitis

Advanced Science, EarlyView.
During pancreatitis, IL‐1α is released from necrotic acinar cells. In response to IL‐1α, pancreatic fibroblasts release chemokines and cytokines that regulate the recruitment of immune cells to the damaged organ. Furthermore, IL‐1α primes fibroblasts, resulting in increased tissue fibrosis during chronic pancreatitis.

Testing of distributions, minimax optimality and extensions [PDF]

, 2021
The subject of this thesis is a minimax optimal study of statistical inference, with a focus on hypothesis testing. This will give us the opportunity of reviewing tools and ideas from the literature of estimation and testing of discrete and continuous
