Finite groups in which every self-centralizing subgroup is nilpotent or subnormal or a TI-subgroup [PDF]

open access: yes, 2021
summary:Let $G$ be a finite group. We prove that if every self-centralizing subgroup of $G$ is nilpotent or subnormal or a TI-subgroup, then every subgroup of $G$ is nilpotent or subnormal. Moreover, $G$ has either a normal Sylow $p$-subgroup or a normal

Neural‐Network‐Based Event‐Triggered Consensus Tracking for Nonlinear Heterogeneous Multi‐Agent Systems Against Denial‐of‐Service Attacks

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This article proposes a distributed resilient control framework to ensure consensus tracking for nonlinear heterogeneous multi‐agent systems (NHMAS) under aperiodic denial‐of‐service (DoS) attacks. First, a resilient observer is introduced to estimate the leader's state considering that not all agents have direct access to the leader's ...

New PMCT multi‐indicator ossification standards for age estimation of the knee in modern Australian and North American children

open access: yesJournal of Forensic Sciences, EarlyView.
Abstract Skeletal age estimation is crucial to medicolegal work, aiding subadult identification, and living age assessments in legal contexts. This study aims to document the ontogeny of knee skeletal indicators on post‐mortem computed tomography (PMCT), and quantify interpopulation variation between modern American and Australian children.

Body Mass Index Category Transitions in Childhood and Probability of Obesity at Age 13

open access: yesActa Paediatrica, EarlyView.
ABSTRACT Aim Understanding how children move between Body Mass Index (BMI) categories may improve early detection of those at risk of persistent obesity. This study explored transitions between BMI categories during childhood and their association with the probability of obesity at Age 13.

A tutorial on Bayesian model averaging for exponential random graph models

open access: yesBritish Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract The use of exponential random graph models (ERGMs) is becoming prevalent in psychology due to their ability to explain and predict the formation of edges between vertices in a network. Valid inference with ERGMs requires correctly specifying endogenous and exogenous effects as network statistics, guided by theory, to represent the network ...

Functional equations for zeta functions of groups and rings [PDF]

open access: yes, 2010
We introduce a new method to compute explicit formulae for various zeta functions associated to groups and rings. The specific form of these formulae enables us to deduce local functional equations. More precisely, we prove local functional equations for

Rapid Intrasegmental Progression After Percutaneous Radiofrequency Ablation for Hepatocellular Carcinoma: Incidence, Imaging Features, and Clinical Outcomes

open access: yesHepatology Research, EarlyView.
ABSTRACT Aim Radiofrequency ablation (RFA) is curative therapy for early‐stage hepatocellular carcinoma (HCC), but a rare subset of patients develop aggressive intrasegmental recurrence shortly after complete ablation. We characterized the incidence, risk factors, and absolute risk.

Differential resistance to cell entry by porcine endogenous retrovirus subgroup A in rodent species [PDF]

open access: yes, 2007
Background: The risk of zoonotic infection by porcine endogenous retroviruses (PERV) has been highlighted in the context of pig-to-human xenotransplantation. The use of receptors for cell entry often determines the host range of retroviruses.
