Sudan at War With Itself: Civilian Devastation in the Civil War

Conflict Resolution Quarterly, EarlyView.
ABSTRACT A civil war is raging in Sudan between the Sudan Armed Forces (SAF) and the Rapid Support Forces (RSF) along with militia groups. Beginning on April 15, 2023, and continuing at least to this writing (October 15, 2025), civilian noncombatants have been subjected to bombings, beatings, torture, shootings, rape, and murder on a large scale. Since

Fish Scales: A Multifunctional Biomaterial from Nature

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Fish scales demonstrate nature's solution to impact protection through overlapping multilayered architecture. This biological design combines mineralized surfaces with collagen networks to achieve both flexibility and fracture resistance. The structural principles inspire advanced protective materials and biomedical implants, where damage tolerance ...

Effect of Hydrotreating Severity on Jet Fuel Thermal Oxidation Stability of Olefinic Synthetic Kerosene

Energy Science &Engineering, EarlyView.
The extent of hydrotreating that is required for olefinic kerosene to pass the jet fuel thermal oxidative stability test was investigated. Fouling species are destroyed after mild hydrotreating, and no further benefit is derived from more severe hydrotreating.

Unsteady Flow Behavior and Radial Force Analysis of a Side Channel Pump Under Different Blade Tip Cutting Angles Using Computational Fluid Dynamics

Energy Science &Engineering, EarlyView.
The Radial Force (RF) distribution under different cutting angles is presented in Figure 1. Generally, the distribution of RF displays divergence across different flow conditions. The pattern of force distribution reveals a total of 24 peaks, which corresponds to the number of blades of the impeller of the SCP.

Industry Portfolio Volatility Connections and Industry Portfolio Returns

International Journal of Finance &Economics, EarlyView.
ABSTRACT This paper tracks dynamic connections that form among daily US industry portfolio return volatilities using a Bayesian time‐varying parameter VAR model. Market participants often focus on sectors to filter vast amounts of information, and this focus results in cross‐industry return predictability. We characterise connections that form over the
