Topological Transitions at Optical Interfaces Near Reflection Singularities
Nanophotonics, Volume 15, Issue 7, 13 April 2026.Topological transitions—from ideal to deformed off‐axis vortices—are revealed near optical reflection singularities. Governed by three independent control parameters (incident angle, incident, and reflected polarization states) and extended to PT‐symmetric multilayer systems, this framework enables precise manipulation of structured light and ...

Evaluation of Bruised Plum Quality Using Laser Induced Diffuse Reflectance Imaging
Journal of Food Process Engineering, Volume 49, Issue 4, April 2026.Plums were subjected to bruising by falling from 1 m height. A laser line illuminated the surface and intensity distribution was captured. After curve fitting and statistical evaluation, firmness and SSC were predicted. ABSTRACT Mechanical damage affects the quality of harvested fruit.

Advanced Science, Volume 13, Issue 13, 3 March 2026.The interplay between magnetic ordering and crystal electric field (CEF) excitations plays a pivotal role in defining the low‐energy electrodynamics of quantum materials. By probing the temperature‐dependent THz conductivity in a rare‐earth‐based metallic ferromagnet, we uncover a microscopic connection between localized and itinerant electrons ...

Determination of Optical Constants in the Mid-Infrared Spectral Range by use of the Attenuated Total Reflection Method [PDF]
Kemija u Industriji, 2010 Infrared (IR) spectroscopy is one of the most useful experimental methods in the investigation of hydrogen-bonded systems. However, application of transmission IR spectroscopy to aqueous systems is only of limited value due to the very strong water ...

Strabismus Responsive to Fresnel Prisms Therapy Before Surgery
JAPANESE ORTHOPTIC JOURNAL, 2008 【目的】両眼視が失われていた手術予定の斜視患者にフレネル膜プリズムによる保存的治療を行い、両眼視機能の改善が得られた2症例を報告する。【症例】症例1は5歳女児。2歳頃から内斜視で、他院で眼鏡により経過観察されていたが、軽快せず3歳時に当科を受診した。眼位は完全屈折矯正眼鏡装用にて遠見、近見とも45ΔETで、同時視は認められなかった。手術までの期間、右20Δ基底外方、左15Δ基底外方のフレネル膜プリズム療法を施行したところ、両眼視機能が得られ、斜視角の減少を認めた。症例2は9歳男児。2歳半から母親は眼位異常に気づいていたが、近医で経過観察と指示され9歳時に当科を受診した。眼位はAPCTで近見30ΔXT、DVDを合併していた。同時視認められず恒常性外斜視と診断した ...

Light and electromagnetism through the prism of friendship of Fresnel and Ampère
, 2022 La théorie ondulatoire de la lumière d’Augustin Fresnel et celle de l’électrodynamique d’André-Marie Ampère, sont les fruits d’une véritable collaboration -peu connue- entre deux savants, courageux face aux tenants des théories dominantes, fidèles en amitié et géniaux.
