Network topology drives population temporal variability in experimental habitat networks

open access: yesPopulation Ecology, EarlyView.
Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...

Improving Global Financial Stability [PDF]

open access: yes, 2000
This report concludes that the failure of developing country governments and international financial institutions to adapt to changing markets helped trigger some of the world's financial crises. Arguing that global finance is "more susceptible to crisis

Between Droughts and Floods: The Seasonal Response of Freshwater Snails in Artificial Reservoirs in the Brazilian Semiarid Region

open access: yesPopulation Ecology, EarlyView.
We investigate the seasonal dynamics of two freshwater snails, Biomphalaria straminea and Melanoides tuberculata, in artificial reservoirs of the Brazilian semiarid region. Despite regulated hydrology, B. straminea exhibited strong seasonal fluctuations associated with dry periods, while M. tuberculata maintained stable populations throughout the year,

Mathematical analysis of a human papillomavirus transmission model with vaccination and screening

open access: yesMathematical Biosciences and Engineering, 2020
We formulate a mathematical model to explore the transmission dynamics of human papillomavirus (HPV). In our model, infected individuals can recover with a limited immunity that results in a lower probability of being infected again.

Stability analysis of an unemployment model with time delay

open access: yesAIMS Mathematics, 2021
In this paper, we have developed and analyzed an unemployment model of differential equations with time delay, taking into consideration the role of government for the support of vacancies creation.

CHOICES FOR GLOBAL SOCIAL STABILITY [PDF]

open access: yesIFAC Proceedings Volumes, 2008
Abstract Scientists and societal leaders increasingly agree that human activity is irretrievably changing the environment in which human life and other life forms co-exist. Action to reduce human impact on the environment is an imperative prerequisite to achieving social stability.

Making tau amyloid models in vitro: a crucial and underestimated challenge

open access: yesFEBS Letters, EarlyView.
This review highlights the challenges of producing in vitro amyloid assemblies of the tau protein. We review how accurately the existing protocols mimic tau deposits found in the brain of patients affected with tauopathies. We discuss the important properties that should be considered when forming amyloids and the benchmarks that should be used to ...

Impact of modified biochar on phosphorus fractionation and biochemical properties for different soils

open access: yesEnvironmental Sciences Europe
Modified (metal oxide) biochar is widely used for the remediation of degraded soils, but there has been limited research work on its effect on phosphorus fractionation and biochemical properties under different soil conditions.

Interaction vesicles as emerging mediators of host‐pathogen molecular crosstalk and their implications for infection dynamics

open access: yesFEBS Letters, EarlyView.
Interaction extracellular vesicles (iEVs) are hybrid vesicles formed through host‐pathogen communication. They facilitate immune evasion, transfer pathogens' molecules, increase host cell uptake, and enhance virulence. This Perspective article illustrates the multifunctional roles of iEVs and highlights their emerging relevance in infection dynamics ...
