AI Article Synopsis

  • The article investigates how delays impact the dynamics of a scalar tick population model with two different types of delays.
  • It develops criteria for ensuring the population remains persistent and positive over time, as well as conditions for global attractivity based on time lags.
  • The findings are supported by simulation diagrams that validate the theoretical conclusions drawn in the study.

Article Abstract

The aim of this article is to analyze the delay influence on the attraction for a scalar tick population dynamics equation accompanying two disparate delays. Taking advantage of the fluctuation lemma and some dynamic inequalities, we derive a criterion to assure the persistence and positiveness on the considered model. Furthermore, a time-lag-dependent condition is proposed to insure the global attractivity for the addressed model. Besides, we give some simulation diagrams to substantiate the validity of the theoretical outcomes.

Many scholars argue that there is a deepening crisis of trust in healthcare systems. What is not contested is the centrality of public trust in building reputational value in healthcare organisations. However, there is a dearth of research focused on better understanding how trust in healthcare institutions, and the healthcare workforce, can be sustainably cultivated.

Ticks are a significant threat to livestock globally, with certain species displaying distinct host preferences at various developmental stages. Accurate species-level identification is essential for studying tick populations, implementing control strategies, and understanding disease dynamics. This study evaluated ticks infesting cattle across six provinces in South Africa using morphological and molecular methods.

The bacterium responsible for Lyme disease, , accumulates high levels of manganese without iron and possesses a polyploid genome, characteristics suggesting potential extreme resistance to radiation. Contrary to expectations, we report that wild-type B31 cells are radiosensitive, with a gamma-radiation survival limit for 10 wild-type cells of <1 kGy. Thus, we explored radiosensitivity through electron paramagnetic resonance (EPR) spectroscopy by quantitating the fraction of Mn present as antioxidant Mn metabolite complexes (H-Mn).

Background: Epidemiological surveys have monitored chronic non-cancer pain (CNCP) and investigated associated factors in Denmark for more than 20 years. This study aimed to analyse CNCP prevalence in the Danish population from 2000 to 2023 and its associations with mental health status and loneliness.

Methods: Population-based surveys were conducted between 2000 and 2023.
