J B Sokoloff

Phys Rev E 2022 Apr;105(4-1):044606

Physics Department, Northeastern University, Boston, Massachusetts 02115, USA and Physics Department, Florida Atlantic University, Boca Raton, Florida 33431, USA.

Electrical image potentials can be important in small spaces, such as nanoscale pores in porous electrodes, which are used in capacitive desalination and in supercapacitors, as argued by Bazant's group at Massachusetts Institute of Technology. It will be shown here that inside pores in porous metallic materials the image potentials can be considerably larger than near flat walls, as a result of the fact that the dielectric constant for an electric field perpendicular to a wall is much smaller than the bulk dielectric constant of water. Calculations will be presented for the image potential in spherical and cylindrically shaped pores. Read More

Freshwater influx to the Eastern Mediterranean Sea from the melting of the Fennoscandian ice sheet during the last deglaciation.

Sci Rep 2022 May 19;12(1):8466. Epub 2022 May 19.

Atmosphere and Ocean Research Institute, The University of Tokyo, 5-1-5, Kashiwanoha, Kashiwa, Chiba, 277-8568, Japan.

Between the Last Glacial Maximum and the mid-Holocene, the Mediterranean Sea experienced major hydrological changes. The deposition of the last sapropel, S1, during the Early Holocene is a consequence of these changes. In order to cause anoxia in the Eastern Mediterranean Sea (EMS) bottom water, a long preconditioning period of a few thousand years would need to occur throughout the deglaciation prior to S1.

Forecasting large-scale circulation regimes using deformable convolutional neural networks and global spatiotemporal climate data.

Sci Rep 2022 May 19;12(1):8395. Epub 2022 May 19.

Department of Electrical and Computer Engineering, Aarhus University, Aarhus, Denmark.

Classifying the state of the atmosphere into a finite number of large-scale circulation regimes is a popular way of investigating teleconnections, the predictability of severe weather events, and climate change. Here, we investigate a supervised machine learning approach based on deformable convolutional neural networks (deCNNs) and transfer learning to forecast the North Atlantic-European weather regimes during extended boreal winter for 1-15 days into the future. We apply state-of-the-art interpretation techniques from the machine learning literature to attribute particular regions of interest or potential teleconnections relevant for any given weather cluster prediction or regime transition.

Ecological divergence of wild birds drives avian influenza spillover and global spread.

PLoS Pathog 2022 May 19;18(5):e1010062. Epub 2022 May 19.

Department of Infectious Disease and Global Health, Cummings School of Veterinary Medicine Tufts University, North Grafton, Massachusetts, United States of America.

The diversity of influenza A viruses (IAV) is primarily hosted by two highly divergent avian orders: Anseriformes (ducks, swans and geese) and Charadriiformes (gulls, terns and shorebirds). Studies of IAV have historically focused on Anseriformes, specifically dabbling ducks, overlooking the diversity of hosts in nature, including gull and goose species that have successfully adapted to human habitats. This study sought to address this imbalance by characterizing spillover dynamics and global transmission patterns of IAV over 10 years at greater taxonomic resolution than previously considered.

Major environmental drivers determining life and death of cold-water corals through time.

PLoS Biol 2022 May 19;20(5):e3001628. Epub 2022 May 19.

MARUM-Center for Marine Environmental Sciences, University of Bremen, Bremen, Germany.

Cold-water corals (CWCs) are the engineers of complex ecosystems forming unique biodiversity hotspots in the deep sea. They are expected to suffer dramatically from future environmental changes in the oceans such as ocean warming, food depletion, deoxygenation, and acidification. However, over the last decades of intense deep-sea research, no extinction event of a CWC ecosystem is documented, leaving quite some uncertainty on their sensitivity to these environmental parameters.
