Faraday–Ramsey Rotation in Ultrathin Alkali Vapor Cells as an Analogy to Atomic‐Beam Systems

open access: yesLaser &Photonics Reviews, EarlyView.
This work demonstrates that ultrathin rubidium vapor cells can emulate atomic‐beam behavior through geometry‐dependent velocity filtering. Employing a spatially separated pump–probe scheme and Faraday–Ramsey rotation, the study reveals coherent atomic dynamics without buffer gas or anti‐relaxation coatings. This approach offers a compact pathway toward

Alpine flora of Kashmir Himalaya: floristic assessment, life history traits and threat status

open access: yesNordic Journal of Botany, EarlyView.
Alpine ecosystems in the Himalaya are considered to be at a higher risk to anthropogenic global change drivers. The Kashmir Himalaya, located in the north‐western side of the Himalayan biodiversity hotspot, harbors a diverse alpine flora, which remains systematically little investigated.

Engaging the public in plant science: Communication facilitators and barriers of scaling up a citizen science campaign

open access: yesPeople and Nature, EarlyView.
Abstract Volunteers have been involved in nature observations for decades through citizen science initiatives, providing large data sets as well as problem identification that allow a more complete understanding of many natural phenomena. Although communication is a core component in citizen science, the key factors that determine its effectiveness in ...

Wilting wildflowers and bummed‐out bees: Climate change threatens US state symbols

open access: yesPeople and Nature, EarlyView.
Abstract Species designated as state symbols in the United States carry cultural importance, embody historical heritage and maintain long‐standing linkages to Indigenous traditions. However, they are threatened by climate change and even face the risk of local or global extinction.

Genetic analysis of primary lung interdigitating dendritic cell sarcomas

open access: yesThe Journal of Pathology, EarlyView.
Abstract Interdigitating dendritic cell sarcomas (IDCSs) are rare tumors that commonly arise in the hematopoietic system and rarely outside. The genetic drivers of IDCS carcinogenesis are unknown; therefore, therapeutic options are limited. We investigated somatic gene mutations and copy‐number alterations (CNAs) in nine IDCSs arising in the lung by ...

Prenatal Diagnosis and Management of Kaposiform Hemangioendothelioma With Kasabach–Merritt Phenomenon: Imaging Features and First Experience With Maternal Sirolimus Therapy

open access: yesPrenatal Diagnosis, EarlyView.
ABSTRACT Objective To describe the prenatal diagnosis, evolution, and perinatal management of kaposiform hemangioendothelioma (KHE) complicated by the Kasabach–Merritt phenomenon (KMP), and to report the first documented use of maternal sirolimus therapy (MST) in this setting. Methods We retrospectively reviewed four fetuses with a prenatal soft‐tissue

Development of Cost‐Effective and Highly Transparent Melamine Formaldehyde Resin Modified With Sodium Chloride for Enhancing Glossiness and Abrasion Resistance of Melamine Impregnated Paper

open access: yesPolymer Engineering &Science, EarlyView.
An eco‐friendly melamine‐formaldehyde was produced by the addition of sodium chloride as a modifier. Modified MF resin improved surface gloss and abrasion resistance of decorative paper and decreased the formaldehyde emission. Curing time of the MF resin decreased with the addition of sodium chloride.
