Human Fragmentation Effects Are Genetically Detectable After 6 Years in an Island-Endemic Plant. [PDF]

Ecol Evol
We provide direct evidence that anthropogenic infrastructures such as reservoirs and expressways have been capable of increasing genetic differentiation and, thus, modifying the phylogeographical pattern of Primulina heterotricha in just a six‐year period (two generations of the plant). ABSTRACT Anthropogenic disturbances have long been acknowledged to

Vaping causes an acute BMI-dependent change in pulmonary blood flow. [PDF]

Physiol Rep
The effect of vaping on the lungs is not yet well understood; previous studies have shown mixed results. We applied functional MRI methods to measure regional ventilation and perfusion in the lungs before and after vaping. Results showed a strong correlation between BMI and the change in perfusion after vaping. Measurements of airways resistance showed

Longitudinal patterns of brain aging and neurodegeneration among older adults with dual decline in memory and gait. [PDF]

Alzheimers Dement
Abstract INTRODUCTION Dual cognitive and mobility decline is more strongly associated with dementia risk than cognitive decline only. It remains unknown whether this syndrome is associated with brain atrophy patterns, white matter (WM) damage, or pathology. METHODS In the Baltimore Longitudinal Study of Aging participants with and without dual decline,

Interleukin-18 Gene Polymorphisms and Rheumatoid Arthritis Susceptibility: An Umbrella Review of Meta-Analyses. [PDF]

J Immunol Res
This study systematically analyzes the association between interleukin‐18 (IL‐18) gene polymorphisms and rheumatoid arthritis (RA) susceptibility. The electronic databases Ovid MEDLINE, Ovid Excerpta Medica Database, and Cochrane Library were searched to identify meta‐analyses that included case–control studies reporting IL‐18 gene polymorphisms and RA

A Water Stable U(IV) Complex Based on a Macrocyclic Ligand Displaying NIR Emission. [PDF]

Chemistry
A water‐stable U(IV) complex is obtained by coordination of U(IV) with a nonadentate macrocyclic ligand based on a triazacyclononane platform. The U(IV) cation is fully protected from coordination of water molecules, and upon excitation into the UV‐Visible region, the complex displays an unprecedented NIR emission from U(IV). Abstract Complexation of U(

R5: Rule Discovery with Reinforced and Recurrent Relational Reasoning [PDF]

International Conference on Learning Representations, 2022
Systematicity, i.e., the ability to recombine known parts and rules to form new sequences while reasoning over relational data, is critical to machine intelligence. A model with strong systematicity is able to train on small-scale tasks and generalize to

On the short-range behavior of neutrino forces beyond the Standard Model: from 1/r5 to 1/r4, 1/r2, and 1/r [PDF]

Journal of High Energy Physics, 2021
The exchange of a pair of neutrinos between two objects, seperated by a distance r, leads to a long-range effective potential proportional to 1/r5, assuming massless neutrinos and four-fermion contact interactions.

Towards high-throughput screening (HTS) of polyhydroxyalkanoate (PHA) production via Fourier transform infrared (FTIR) spectroscopy of Halomonas sp. R5-57 and Pseudomonas sp. MR4-99

PLoS ONE, 2023
High-throughput screening (HTS) methods for characterization of microbial production of polyhydroxyalkanoates (PHA) are currently under investigated, despite the advent of such systems in related fields. In this study, phenotypic microarray by Biolog PM1
