A study of anti-SARS-CoV-2 antibodies among healthcare personnel and the general population

open access: yesBiotechnology & Biotechnological Equipment, 2023
Bulgaria, like many other countries, has experienced the far-reaching consequences of the Coronavirus disease 2019 (COVID-19) pandemic. Seroprevalence studies serve as a crucial method for assessing the exposure and immunity levels within a population ...

Whole MILC: Generalizing Learned Dynamics Across Tasks, Datasets, and Populations [PDF]

open access: yes, 2020
Behavioral changes are the earliest signs of a mental disorder, but arguably, the dynamics of brain function gets affected even earlier. Subsequently, spatio-temporal structure of disorder-specific dynamics is crucial for early diagnosis and understanding the disorder mechanism.

Population dynamics in spatially heterogeneous systems with drift: The generalized contact process [PDF]

open access: yesPhysical Review E, 2005
We investigate the time evolution and stationary states of a stochastic, spatially discrete, population model (contact process) with spatial heterogeneity and imposed drift (wind) in one- and two-dimensions. We consider in particular a situation in which space is divided into two regions: an oasis and a desert (low and high death rates).

Generating synthetic population for simulating the spatiotemporal dynamics of epidemics

open access: yesPLOS Computational Biology
Agent-based models have gained traction in exploring the intricate processes governing the spread of infectious diseases, particularly due to their proficiency in capturing nonlinear interaction dynamics. The fidelity of agent-based models in replicating real-world epidemic scenarios hinges on the accurate portrayal of both population-wide and ...

The effect of temporal environmental autocorrelation on eco‐evolutionary dynamics across life histories

open access: yesEcosphere, 2020
One of the largest causes of fluctuations in the size and structure of populations is changes in the environment. In nature, these changes are often temporally autocorrelated and the strength and direction of the autocorrelation can affect population ...
