Assessing Radar Attenuation in RIMFAX Soundings at the Jezero Western Fan Front, Mars
(2024-07-02)Estimates of radar attenuation in the shallow Martian subsurface are retrieved from RIMFAX soundings along the Perseverance rover traverse. Specifically, analyzed data is from the Hawksbill Gap area during the rover's first ... -
Capture and Release of Minke Whales Offers New Research Opportunities, Including Measurements of Mysticete Hearing
(2024-09)Knowledge about species-specific hearing is vital to assessing how anthropogenic noise impacts marine mammals. Unfortunately, no empirical audiogram exists for any mysticete whale. We therefore developed a catch-and-release ... -
Riding the yellow wave: the online populist communication of Rassemblement National (RN) leaders in response to the Gilets Jaunes protests and the 2019 European elections
(2024-07-02)Radical-right populist parties will often try to exploit and ride a wave of popular discontent for their own electoral gain. This paper studies the online populist communication of the leaders of the Rassemblement National ... -
Failures in Ukrainian Arms Procurement 2014-2023 The Negative Effects of Limited Access Orders (LAOs) on National Security
(2024-07-15)This article discusses critical failures in Ukrainian defense production and procurement in the period 2014 to 2023. The main puzzle is why Ukraine did so little to satisfy the needs of the country’s armed forces in essential ... -
Glyceraldehyde metabolism in mouse brain and the entry of blood-borne glyceraldehyde into the brain
(2024-06-22)D-Glyceraldehyde, a reactive aldehyde metabolite of fructose and glucose, is neurotoxic in vitro by forming advanced glycation end products (AGEs) with neuronal proteins. In Alzheimer's disease brains, glyceraldehyde-containing ... -
Generalizing the Black and Scholes Equation Assuming Differentiable Noise
(2024-10-09)This article develops probability equations for an asset value through time, assuming continuous correlated differentiable Gaussian distributed noise. Ito’s (1944) stochastic integral and a generalized Novikov’s (1919) ... -
Model selection techniques for seafloor scattering statistics in synthetic aperture sonar images of complex seafloors
(2024-06-30)In quantitative analysis of seafloor scattering measurements, it is common to model the single-point probability density function of the scattered intensity or amplitude. For more complex seafloors, the pixel amplitude ... -
Electric field gradients at the nuclei from all-electron four-component relativistic density functional theory using Gaussian-type orbitals
(2024-07-23)We present an all-electron, four-component relativistic implementation of electric field gradients (EFGs) at the nuclei using Gaussian-type orbitals and periodic boundary conditions. This allows us to include relativistic ... -
