Bone fracture detection through the two-stage system of Crack-Sensitive Convolutional Neural Network

Yangling Ma, Yixin Luo • Informatics in Medicine Unlocked (2021)

Automated fracture detection is an essential part in a computer-aided tele-medicine system. Fractures often occur in human's arbitrary bone due to accidental injuries such as slipping. In fact, many hospitals lack experienced surgeons to di...

Dijet production in diffractive deep-inelastic scattering in next-to-next-to-leading order QCD

D. Britzger, J. Currie, T. Gehrmann, A. Huss et al. • European Physical Journal C: Particles and Fields (2018)

Abstract Hard processes in diffractive deep-inelastic scattering can be described by a factorisation into parton-level subprocesses and diffractive parton distributions. In this framework, cross sections for inclusive dijet production in di...

ZOTMPo–INAR(1) Process: Entropy and Modeling of Epidemiological Count Time Series Data

Manik Awale, Shrirang Pund, Hassan S. Bakouch, Aishwarya Ghodake et al. • Entropy (2026)

In this article, we propose a first-order integer-valued autoregressive (INAR(1)) model based on binomial thinning, in which the innovation sequence follows a zero–one–two-modified Poisson (ZOTMPo) distribution. The proposed model accommoda...

Studies of the epidemiology of bulimia nervosa

Christopher G. Fairburn, Sarah J. Beglin • American Journal of Psychiatry (1990)

Research on the epidemiology of bulimia nervosa has focused largely on the prevalence of the disorder. As methods have improved, consensus has increased regarding the prevalence rate among adolescent and young adult women--about 1%. However...
