Medical Physics, Volume 53, Issue 7, July 2026.Abstract Background Accurate range verification is crucial in hadrontherapy to fully exploit the ballistic advantages of charged particles and prevent damage to healthy tissues. Among the proposed approaches, prompt gamma imaging (PGI) has emerged as an effective technique for real‐time monitoring, but its performance is limited by the intense neutron ...

When does category spanning hurt or help producers?
Strategic Management Journal, Volume 47, Issue 7, Page 1907-1934, July 2026.Abstract Research Summary Scholars have theorized many factors shaping whether category spanning helps or hurts producers. We first synthesize evidence by meta‐analyzing 25 years of empirical research, which reveals a null effect of spanning on average, yet with significant subsample heterogeneity. To unpack it, we theorize and find that spanning hurts

A Different Position: Protest Medicine and the Limits of Professional Neutrality
Sociology of Health &Illness, Volume 48, Issue 6, July 2026.ABSTRACT Protests are a persistent feature of contemporary urban life, often producing mass injuries through police repression. Yet the role of medical care in these contexts—especially when provided by informal collectives—remains understudied. Drawing on 21 in‐depth interviews with members of volunteer medical brigades during Chile's 2019–2020 ...

Journal of Forensic Sciences, Volume 71, Issue 4, Page 1607-1620, July 2026.Abstract Forensic ballistics is essential in analyzing evidence from firearm use in criminal investigations, with gunshot residue (GSR) detection providing key information about the firearm and shooting conditions. Traditional methods like spectroscopy and scanning electron microscopy (SEM) have limitations in sensitivity, cost, and accessibility ...

American Journal of Political Science, Volume 70, Issue 3, Page 925-945, July 2026.Abstract How can defense alliances reap the efficiency gains of working together when coordination and opportunism costs are high? Although specializing as part of a collective comes with economic and functional benefits, states must bargain over the distribution of those gains and ensure the costs of collective action are minimized.

Kinetic Compensation of Barrel Launch Under High‐Speed Solid‐Phase Particulate Impacts
International Journal of Mechanical System Dynamics, Volume 6, Issue 2, Page 313-326, June 2026.ABSTRACT An accurate launch‐dynamics computational method is critical for barrel weapon service life assessment and multiphase physics field refinement. Given the lack of studies on the solid‐phase buildup behavior at the projectile base, this paper provides an improved method for calculating the launching dynamics under high pressure and high speed ...
