Large-eddy simulations with ClimateMachine: a new open-source code for atmospheric simulations on GPUs and CPUs [PDF]

, 2021
We introduce ClimateMachine, a new open-source atmosphere modeling framework using the Julia language to be performance portable on central processing units (CPUs) and graphics processing units (GPUs). ClimateMachine uses a common framework both for coarser-resolution global simulations and for high-resolution, limited-area large-eddy simulations (LES).

Early‐onset Alzheimer's disease shows a distinct neuropsychological profile and more aggressive trajectories of cognitive decline than late‐onset

Annals of Clinical and Translational Neurology, Volume 9, Issue 12, Page 1962-1973, December 2022., 2022
Abstract Objectives Early‐ and late‐onset Alzheimer's disease (EOAD and LOAD) share the same neuropathological traits but show distinct cognitive features. We aimed to explore baseline and longitudinal outcomes of global and domain‐specific cognitive function in a well characterized cohort of patients with a biomarker‐based diagnosis.

Comparison of the measured atmospheric muon flux with Monte Carlo simulations for the first KM3NeT detection units [PDF]

PoS(ICRC2019)927, 2021
The KM3NeT Collaboration has successfully deployed its first detection units in the Mediterranean Sea in December 2015 (ARCA) and September 2017 (ORCA). The sample of data collected between September 2016 and March 2017 has been used to measure the atmospheric muon flux at two different depths under the sea level: about 3.5\,km with ARCA and about 2.5\,

The effect of varying atmospheric pressure upon habitability and biosignatures of Earth-like planets [PDF]

Astrobiology, Volume 18, Issue 2, 2018, pp.116-132, 2020
Understanding the possible climatic conditions on rocky extrasolar planets, and thereby their potential habitability, is one of the major subjects of exoplanet research. Determining how the climate, as well as potential atmospheric biosignatures, change under different conditions is a key aspect when studying Earth-like exoplanets.

Comparative genomics highlight the importance of lineage-specific gene families in evolutionary divergence of the coral genus, Montipora

BMC Ecology and Evolution, 2022
Background Scleractinian corals of the genus Montipora (Anthozoa, Cnidaria) possess some unusual biological traits, such as vertical transmission of algal symbionts; however, the genetic bases for those traits remain unknown.

The transient response of global-mean precipitation to increasing carbon dioxide levels [PDF]

, 2010
The transient response of global-mean precipitation to an increase in atmospheric carbon dioxide levels of 1% yr(-1) is investigated in 13 fully coupled atmosphere-ocean general circulation models (AOGCMs) and compared to a period of stabilization ...
