What Is the Return on Investment of Digital Engineering for Complex Systems Development Schedules? Findings From a Mixed‐Methods Case Study on the Post‐Production Design Change Processes of Navy Assets

Systems Engineering, EarlyView.
ABSTRACT Complex engineered systems routinely face schedule and cost overruns, along with poor post‐deployment performance. Both INCOSE and the U.S. Department of Defense (DoD) have championed Digital Engineering (DE) as a potential remedy, yet most of DE's purported benefits remain anecdotal, and its return on investment (ROI) remains poorly ...

Prognostic Value of Initial CT Imaging for Surgical Planning and Outcomes in Panfacial Fractures: A Systematic Review and Meta‐Analysis

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objective To evaluate the reported prognostic value of initial computed tomography (CT) imaging for surgical planning and postoperative outcomes in panfacial fractures, and to determine whether CT‐derived variables have been consistently linked to clinically relevant outcomes.

Preparing to Fight the ‘Wrong War’? Why the UK Defence Budget Must Focus More on ‘National Resilience’

The Political Quarterly, EarlyView.
Abstract This article argues that the current debate over defence spending in the United Kingdom is fundamentally flawed. Too much emphasis is being placed on preparing for a form of warfare with Russia that is unlikely to occur. As this article points out, the Russians actually want to avoid a traditional battlefield confrontation with NATO.

Region‐of‐interest geometry optimization for shooting‐distance estimation from flash‐pulse infrared thermography of gunshot residue on textile targets

Journal of Forensic Sciences, EarlyView.
Abstract Shooting‐distance estimation from gunshot‐residue (GSR) patterns on textiles is affected by substrate properties, residue distribution, and region‐of‐interest (ROI) definition. This study evaluated how ROI geometry influences muzzle‐to‐target distance regression from flash‐pulse infrared thermography of GSR‐related thermal patterns.

Moderate is the New Black: Shifts and Intersections in Saudi Arabia's Domestic and Foreign Policy

Global Policy, EarlyView.
ABSTRACT The Kingdom of Saudi Arabia (KSA) is undergoing a period of intense changes. Its current stage of transformation has been led by Prince Mohammed bin Salman (MbS) since 2015, seeking to turn the Kingdom into a story of successful governance and one of the leading powers in the Middle East. In hardly understood yet very consequential ways, KSA's
