Collective motion and its connection to the energy landscape in 2D soft crystals.
Soft Matter
January 2025
Physics Department, Wesleyan University, Middletown, CT 06459, USA.
We examine the collective motion in computational models of a two-dimensional dusty plasma crystal and a charged colloidal suspension as they approach their respective melting transitions. To unambiguously identify rearrangement events in the crystal, we map the trajectory of configurations from an equilibrium molecular dynamics simulation to the corresponding sequence of configurations of local potential energy minima ("inherent structures"). This inherent structure (IS) trajectory eliminates the ambiguity that arises from localized vibrational motion.

Purpose: Energy is a health issue. Energy intersects with health outcomes, as evidenced by the relationship between access to clean fuels and technologies and population health measured by life expectancy at birth.
Methods: Utilizing a comprehensive dataset spanning 190 countries from 2000 to 2022, this paper employs a range of static and dynamic panel data models to analyze this empirical relationship, while effectively managing unobserved country-specific heterogeneity and endogeneity issues.
Impact of Botfly Parasitism on the Behavior of Mantled Howler Monkeys.

Parasitism, a widespread nutrient acquisition strategy among animals, results from a long evolutionary history where one species derives its metabolic needs from another. Parasites can significantly reduce host fitness, affecting reproduction, growth, and survivability. Vertebrate hosts exhibit defensive strategies against parasites, including "sickness behaviors" such as lethargy and self-grooming to remove ectoparasites.

January 2025
Institute for Health Metrics and Evaluation, University of Washington, Seattle, WA, USA.
Background: Undernutrition remains a global crisis and is a focus of Sustainable Development Goals. While there are multiple known, effective interventions, complex interactions between prevention and treatment and resource constraints can lead to difficulties in allocating funding. Simulation studies that use in silico simulation can help illuminate the interactions between interventions and provide insight into the cost-effectiveness of alternative packages of options.

Environmental degradation is a problem, and the consequences, in terms of emission of pollutants into different ecosystems, human health, and sustainable development are disastrous. This study explains the complex interactions that exist among sustainable finance, green technology innovation, green energy adoption, the climate change financial policy, green growth index, government spending, and financial globalization across the globe. This research applies to an extensive dataset that ranges to 23 years in 50 countries by enforcing robust dynamic econometric methods such as unit root tests, cointegration analysis, and generalized method of moments (GMM) estimations for the analysis of these complicated issues.
