Systems of Delay Differential Equations: Analysis of a model with feedback [PDF]

open access: yesarXiv, 2016
Self-regulatory models are common in nature, as described e.g. in (\cite{mur}), (\cite{ha}) and (\cite{Gb}).\\ Let us consider a system made up of a number of glands as a motivation. Each gland secretes a hormone that allows secretion in the {next} gland, which successively generates another hormone to stimulate the next one and so on.

Systematic review and meta‐analysis of COVID‐19 association with human semen quality: Changes in semen parameters pre‐ and post‐COVID

open access: yesUroPrecision, EarlyView.
Abstract Coronavirus disease (COVID‐19) is caused by the severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2), which may infect the cells through binding with the angiotensin‐converting enzyme 2 (ACE2) receptors that can also be found in the male reproductive organs.

A Dual-Hormone Closed-Loop Delivery System for Type 1 Diabetes Using Deep Reinforcement Learning [PDF]

open access: yesarXiv, 2019
We propose a dual-hormone delivery strategy by exploiting deep reinforcement learning (RL) for people with Type 1 Diabetes (T1D). Specifically, double dilated recurrent neural networks (RNN) are used to learn the hormone delivery strategy, trained by a variant of Q-learning, whose inputs are raw data of glucose \& meal carbohydrate and outputs are dual-

Development and application of microfluidic sweat detection technology in mental health monitoring

open access: yesVIEW, EarlyView.
In this review, the authors emphasize the potential of microfluidic sweat detection technology in the field of mental health monitoring. The work explores the intricate relationship between psychological disorders, such as depression and anxiety, and their physiological impact, emphasizing how these conditions can influence systemic health. Furthermore,

Acquired narcolepsy secondary to a presumptive hypothalamic hamartoma in a young German wirehaired pointer dog

open access: yesVeterinary Record Case Reports, EarlyView.
Abstract A 3‐year‐old, male, entire, German wirehaired pointer dog was presented with a 2‐year history of paroxysmal episodes of collapse associated with reduced levels of consciousness. A magnetic resonance imaging study identified a single, ill‐defined, non‐contrast‐enhancing, intra‐axial mass lesion involving the hypothalamus.

Pituitary apoplexy is associated with concurrent or subsequent diagnosis of human immunodeficiency virus

open access: yesWorld Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
Abstract Objective Pituitary apoplexy (PA) is a rare condition caused by hemorrhage or infarction of the pituitary gland with associated risk of cranial neuropathies, endocrinopathies, and even death. Human immunodeficiency virus (HIV) has been shown to have some association with pituitary apoplexy, however, large‐scale studies have not been performed.

Behavioural responses of brown bears to helicopter capture

open access: yesWildlife Biology, EarlyView.
Understanding the effects of capture and handling on wild animals is crucial in evaluating ethical practices in ecological research, and in avoiding biased conclusions from misinterpreting biologging data potentially affected by capture. The aim of this study was to assess the effects of helicopter capture on the behaviour of Scandinavian brown bears ...
