Spectroscopic and photometric time series of the bright RRc star T Sex [PDF]
, 2020 We present spectroscopic time series observations on one of the brightest northern RRc star, T Sex. Additionally, we also analysed extended photometric data sets, particularly the recent observations of the TESS space telescope. The main findings of our studies are as follows: T Sex, unlike all RRc stars whose space photometry has been analysed, shows ...

Recognizing early MRI signs (or their absence) is crucial in diagnosing metachromatic leukodystrophy
Annals of Clinical and Translational Neurology, Volume 9, Issue 12, Page 1999-2009, December 2022., 2022 Abstract Objectives Metachromatic leukodystrophy (MLD) has characteristic white matter (WM) changes on brain MRI, which often trigger biochemical and genetic confirmation of the diagnosis. In early or pre‐symptomatic disease stages, these typical MRI changes might be absent, hampering early diagnosis.

Sex Trouble: Common pitfalls in incorporating sex/gender in medical machine learning and how to avoid them [PDF]
, 2022 False assumptions about sex and gender are deeply embedded in the medical system, including that they are binary, static, and concordant. Machine learning researchers must understand the nature of these assumptions in order to avoid perpetuating them. In this perspectives piece, we identify three common mistakes that researchers make when dealing with ...

Automated Sex Classification of Children's Voices and Changes in Differentiating Factors with Age [PDF]
arXiv, 2022 Sex classification of children's voices allows for an investigation of the development of secondary sex characteristics which has been a key interest in the field of speech analysis. This research investigated a broad range of acoustic features from scripted and spontaneous speech and applied a hierarchical clustering-based machine learning model to ...

Robustness Against Extinction by Stochastic Sex Determination in Small Populations [PDF]
Phys. Rev. E 86, 041104 (2012), 2012 Sexually reproducing populations with small number of individuals may go extinct by stochastic fluctuations in sex determination, causing all their members to become male or female in a generation. In this work we calculate the time to extinction of isolated populations with fixed number $N$ of individuals that are updated according to the Moran birth ...

Molecular Oncology, EarlyView.The authors applied joint/mixed models that predict mortality of trifluridine/tipiracil‐treated metastatic colorectal cancer patients based on circulating tumor DNA (ctDNA) trajectories. Patients at high risk of death could be spared aggressive therapy with the prospect of a higher quality of life in their remaining lifetime, whereas patients with a ...

Sex Characteristics in Monkeys.
Experimental Biology and Medicine, 1928 Female monkeys during sexually mature life show the sex characteristics of reddening and swelling of the skin about the external genital organs, on the buttocks and medial surfaces of the thighs. These phenomena disappear after double ovariectomy and can again be induced in spayed animals by injections of ovarian and placental extracts.1 Three male ...
