Published: December 2007

We report measured dipolar asymmetry ratios at the LIII edges of the heavy rare-earth metals. The results are compared with a first-principles calculation and excellent agreement is found. A simple model of the scattering is developed, enabling us to reinterpret the resonant x-ray scattering in these materials and to identify the peaks in the asymmetry ratios with features in the spin and orbital moment densities.

High-throughput untargeted metabolomics reveals metabolites and metabolic pathways that differentiate two divergent pig breeds.

Metabolomics can describe the molecular phenome and may contribute to dissecting the biological processes linked to economically relevant traits in livestock species. Comparative analyses of metabolomic profiles in purebred pigs can provide insights into the basic biological mechanisms that may explain differences in production performances. Following this concept, this study was designed to compare, on a large scale, the plasma metabolomic profiles of two Italian heavy pig breeds (Italian Duroc and Italian Large White) to indirectly evaluate the impact of their different genetic backgrounds on the breed metabolomes.

Relativistic EELS scattering cross-sections for microanalysis based on Dirac solutions.

Ultramicroscopy

March 2025

Department of Materials, University of Oxford, 16 Parks Road, Oxford OX1 3PH, United Kingdom. Electronic address:

The rich information of electron energy-loss spectroscopy (EELS) comes from the complex inelastic scattering process whereby fast electrons transfer energy and momentum to atoms, exciting bound electrons from their ground states to higher unoccupied states. To quantify EELS, the common practice is to compare the cross-sections integrated within an energy window or fit the observed spectrum with theoretical differential cross-sections calculated from a generalized oscillator strength (GOS) database with experimental parameters. The previous Hartree-Fock-based and DFT-based GOS are calculated from Schrödinger's solution of atomic orbitals, which does not include the full relativistic effects.

Purpose: To commission the RayStation (RS) TPS (treatment planning system) for scanned CIRT (carbon-ion radiotherapy) utilizing pencil beam algorithms (PBv4.2).

Methods: The beam model commissioning entailed employing 1D single beams and 2D monoenergetic fields to validate spot profiles with films, assess beam range using Peakfinder measurements, and evaluate fragment spectra through dose-averaged linear energy transfer (LETd) calculations.

Article Synopsis
  • The U.S. swine industry faces disease spread risks due to structural issues, and integrating human movement data with animal movement models provides a more accurate understanding of these risks.
  • An analysis of a year’s worth of farm visit data from three swine management companies revealed a highly connected network with 455 properties, demonstrating that human movements significantly enhance network connectivity compared to animal movements alone.
  • The study suggests that certain properties act as 'hubs' making them potential points for disease spread, indicating that swine farm networks are more vulnerable to disease outbreaks than previously thought based solely on animal movement.

This study introduces a novel approach of precisely depositing InO nanoislands on the edges of BN sheets using selective atomic layer deposition. The modified catalysts demonstrated a significant improvement and characterization results revealed that the presence of InO nanoislands, when free of BO overlayers, is crucial in mitigating side reactions.
