Silicon Photonic Beam Steerer Based on Metalens Focal Plane Array

Nanophotonics, Volume 15, Issue 17, 11 September 2026.
A silicon photonic beam steerer based on a metalens focal plane array (FPA) monolithically integrates the collimation lens on‐chip while enabling blind‐spot‐free continuous beam steering. Thermo‐optic prisms provide continuous fine‐tuning and more than double the number of resolvable points.

Importance of noise models in FSO communications [PDF]

EURASIP Journal on Wireless Communications and Networking, 2014
يعد الاتصال البصري الفضائي الحر (FSO) تقنية ناشئة توفر نطاقًا تردديًا هائلاً وطيفًا بدون ترخيص ووصلة آمنة للغاية. تُستخدم الثنائيات الضوئية للانهيار الجليدي (APD) عادةً للكشف عن إشارات FSO عالية السرعة، حيث تُظهر الضوضاء توزيع الضوضاء الغاوسية المعتمدة على الإشارة (SDGN) بدلاً من توزيع الضوضاء الغاوسية المستقلة عن الإشارة (الإشارة).

Global Overview of the Use and Effectiveness of Ultraviolet C Technology in Fresh, Minimally Processed Apples and Apple Juice Over the Last 10 Years

Food Science &Nutrition, Volume 14, Issue 9, September 2026.
A decade of UV‐C irradiation in Apple postharvest processing: from whole fruit to juice. ABSTRACT The apple is a fruit with significant economic value and a rich nutritional profile, containing high levels of fiber, vitamins, minerals, and bioactive compounds. However, it is susceptible to chemical‐enzymatic oxidation and microbial spoilage.

The Limits of Regulatory Capture: Explaining the UK Payment Protection Insurance Mis‐Selling Scandal

Public Administration, Volume 104, Issue 3, Page 509-521, September 2026.
ABSTRACT To what extent does regulatory agencies' failure to protect the public from harm result from undue industry influence? We argue that “regulatory capture” is invoked too easily to explain regulatory failure. To re‐examine the relationship between regulatory capture and regulatory failure, we use process‐tracing to study UK regulatory decision ...
