steel research international, Volume 97, Issue 4, Page 2241-2249, April 2026.Cold spray deposition of stainless steel (grade: SS304) is evaluated for marine applications, with emphasis on martensitic transformation during impact. Analytical modeling, simulations, and experiments reveal that helium‐assisted spraying of fine powders promotes cooling below the martensitic start temperature, enabling up to ≈40% austenite to ...

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.Abstract The excess abundance of highly siderophile elements (HSEs), as inferred for the terrestrial planets and the Moon, is thought to record a “late veneer” of impacts after the giant impact phase of planet formation. Estimates for total mass accretion during this period typically assume all HSEs delivered remain entrained in the mantle.

Should more teams “trust the process” of tanking?
Contemporary Economic Policy, Volume 44, Issue 2, Page 408-425, April 2026.Abstract In many professional sport leagues, the worst‐performing teams receive higher probability of earning top draft picks. This provides teams incentives to purposefully lose, or “tank,” if they are not likely to contend for the playoffs or championships.

Numerical simulation study of aluminum particle evaporation combustion process based on SPH method
AIP AdvancesA large variety of metal fuels is usually added to the modern solid rocket propellants to improve the propellant energy and motor specific impulse and to suppress high frequency unstable combustion. Among them, aluminum is the most common additive.

Electrets used to measure exhaust cloud effluents from Solid Rocket Motor (SRM) during demonstration model (DM-2) static test firing [PDF]
Electrets were compared with fixed flow samplers during static test firing. The measurement of the rocket exhaust effluents by samplers and electrets indicated that the Solid Rocket Motor had no significant effect on the air quality in the area sampled ...

International Journal of Applied Ceramic Technology, Volume 23, Issue 2, April 2026.This graphical abstract illustrates the systematic investigation of Spark Plasma Sintering (SPS) parameters, temperature, pressure, and dwell time, on the densification and mechanical performance of ZrB2–20 vol% SiC composites. It highlights the critical influence of powder processing history (WC vs.

Internal ballistics model update for ASRM dome [PDF]
A previous report (no. 5-32279, contract NAS8-36955, DO 51) describes the measures taken to adapt the NASA Complex Burning Region Model and code so that is was applicable to the Advanced Solid Rocket Motor as envisioned at that time. The code so modified

The Monetary Policy–Commodities Nexus: A Survey
Journal of Economic Surveys, Volume 40, Issue 2, Page 1050-1082, April 2026.ABSTRACT This survey synthesizes evidence on the bidirectional links between commodity markets and monetary policy. On the commodities‐to‐policy side, we review how shocks to energy, food, and metals pass through to inflation, inflation expectations, economic activity, and financial stability in state‐dependent ways that vary by shock type, exposure ...
