All‐Optical Reconfigurable Physical Unclonable Function for Sustainable Security
Advanced Materials, EarlyView.An all‐optical reconfigurable physical unclonable function (PUF) is demonstrated using plasmonic coupling–induced sintering of optically trapped gold nanoparticles, where Brownian motion serves as a robust entropy source. The resulting optical PUF exhibits high encoding density, strong resistance to modeling attacks, and practical authentication ...

Race, Expectations and Evaluations of Police Performance: An Empirical Assessment [PDF]
, 1999 The purpose of the current study is two‐fold. First, using data obtained from a sample of crime victims (n = 122), this study empirically assesses the effect that police officer race has on evaluations of the police. Second, this study provides a greater

Advanced Science, EarlyView.6 nm iron oxide nanoparticles (IONP6) exhibit enzyme‐like activities that scavenge reactive oxygen and nitrogen species (RONS), including nitric oxide (NO). In stroke models, IONP6 promotes microglial polarization toward the M2 phenotype, reduces neuroinflammation, and improves neurological outcomes, offering a promising drug‐free approach to mitigate ...

How Priming Innocence Influences Public Opinion on Police Misconduct and False Convictions: A Research Note [PDF]
, 2017 Issues of innocence have become more salient to the public in recent years, including the problem of police misconduct. However, citizens also tend to be supportive of the police, perceiving them as ethical, honest, and trustworthy.

Menschen, die polizeiliches Handeln filmen, sind deswegen immer wieder strafrechtlicher Verfolgung ausgesetzt. Der Artikel analysiert die rechtliche Unsicherheit im Zusammenhang mit § 201 StGB, der Tonaufnahmen ohne Zustimmung unter Strafe stellt, und beschreibt die potentiell einschüchternde Wirkung dieser Praxis auf Bürger*innen und Journalist*innen.

Advanced Energy Materials, EarlyView.Electric‐field‐driven carbon migration within an oxygen‐functionalized nanodiamond/carbon composite induces the formation of a vertically graded interphase that homogenizes Li‐ion flux and suppresses dendritic nucleation. This hierarchically organized structure stabilizes the electrode–electrolyte interface and delivers durable, dendrite‐free operation

Black Police Associations and the police occupational culture [PDF]
, 2007 In recent years, Black Police Associations (BPAs) have become key forces of change within the police service, involved in minority ethnic recruitment and retention initiatives, working closely with senior management, and also serving as mechanisms of ...
