Dynamics of Rydberg excitations and quantum correlations in an atomic array coupled to a photonic crystal waveguide
(American Physical Society, 2020-08)We study the dynamics of up to two Rydberg excitations and the correlation growth in a chain of atoms coupled to a photonic crystal waveguide. In this setup, an excitation can hop from one atom to another via exponentially ... -
Dormant but Active: Chilling Accumulation Modulates the Epigenome and Transcriptome ofPrunus aviumDuring Bud Dormancy
(Frontiers Media S.A., 2020-07)Temperate deciduous fruit tree species like sweet cherry (Prunus avium) require long periods of low temperatures to trigger dormancy release and flowering. In addition to sequence-based genetic diversity, epigenetic variation ... -
Concerted Action of AMPK and Sirtuin-1 Induces Mitochondrial Fragmentation Upon Inhibition of Ca(2+)Transfer to Mitochondria
(Frontiers Media S.A., 2020-05)Mitochondria are highly dynamic organelles constantly undergoing fusion and fission. Ca(2+)regulates many aspects of mitochondrial physiology by modulating the activity of several mitochondrial proteins. We previously ... -
Communication Strategies To Enhance HIV/STI Prevention, Sexual and Reproductive Health, and Safety Among Migrant Sex Workers at the Mexico-Guatemala Border
(Johns Hopkins University Press, 2020-05)Communication-based interventions have been linked to improved health and social outcomes among underserved populations. Migrant women in sex work face serious health and social inequities, including risks of HIV and other ... -

Pollinator declines and the stability of plant-pollinator networks
(Wiley-Blackwell, 2020-04)Population declines of pollinators constitute a major concern for the fate of biodiversity and associated ecosystem services in a context of global change. Massive declines of pollinator populations driven by habitat loss, ... -
Population dynamics of Melanaphis donacis (Hemiptera: Aphididae) and its Coccinellidae and Syrphidae predators on Arundo donax L.
(Pontificia Universidad Católica de Chile. Facultad de Agronomía e Ingeniería Forestal, 2020)The population density of the aphid Melanaphis donacis (Passerini) was studied in experimental plots of Arundo donax (L.) at the Antumapu Campus of the University of Chile, La Pintana (33 degrees 34' 08 '' S 70 degrees 38' ... -
Satellite Remote Sensing Contributions to Wildland Fire Science and Management

The necroptosis pathway and its role in age-related neurodegenerative diseases: will it open up new therapeutic avenues in the next decade?
(Taylor and Francis Ltd., 2020-07)Introduction: Necroptosis is a programmed form of necrotic cell death. Growing evidence demonstrates that necroptosis contributes to cell demise in different pathological conditions including age-dependent neurodegenerative ... -
Effect of Tip Roundness on the Nanoindentation of Fe Crystals
(Springer New York, 2020-04)Indentation tips are never atomically sharp, but rounded at their end. We use atomistic simulation to study the effect of tip roundness for the particular case of a cube-corner pyramidal indenter by comparing the results ... -
Effect of subsurface voids on the nanoindentation of Fe crystals
(IOP Publishing Ltd., 2020-03)Subsurface voids may strongly affect the response of materials to nanoindentation. We explore these effects for a bcc single-crystalline Fe sample using molecular dynamics simulation. Deformation occurs mainly by nucleation ... -
