Perovskites have attracted widespread attention for laser applications due to their excellent optoelectronic properties. However, perovskite lasers typically exhibit a wavelength shift as pump density increases. Here, we report a pump-induced wavelength shift-free laser achieved using a perovskite nanoplatelet with mixed orthorhombic and tetragonal phase. At 293 K, the tetragonal-phase perovskite
The Sulu Archipelago, nestled between Mindanao and Borneo, has been a melting pot of people and cultures for thousands of years. Major sociopolitical changes marked its history, attracting groups of people or forcing drastic dispersals. Today, the islands host various ethnolinguistic groups, including Sama-Badjaw and Tausug-speaking communities. We surveyed the literature from multiple disciplines
The detection and classification of adversarial techniques from cyber threat intelligence (CTI) text is a critical task in threat analysis and mitigation. While recent transformer-based models have shown promise, their general-purpose nature often limits effectiveness on complex, domain-specific datasets. In this paper, we present a novel model designed to address the challenges of technique class
In the centre of Malmö, Caroli Church stands in quiet suspension—its doors closed, its future uncertain. Neither abandoned nor alive, it occupies a space between preservation and possibility. In a society where churches are increasingly disconnected from their original function, the question lingers: what becomes of the sacred when it no longer serves the ritual? And who, ultimately, decides what

När två oväntade silverspiror dyker upp i Kulturens magasin startar en historisk detektivresa för arkivarien Henrik Ullstad. Jakten på svar leder långt tillbaka i universitetets ceremoniella traditioner – och fram till upptäckter som utmanar den gängse bilden av dessa ikoniska föremål.
Background: Pain in children is undertreated. An assessment scale co-designed with children, parents, and health care professionals could lead to more effective pain assessments and treatment strategies aimed at reducing pain and pain-related symptoms. There are analogue scales validated for self-report of pain in children, but today, children regularly use digital technology, which healthcare sho
Aerosols substantially influence the climate by modifying Earth’s radiative balance and marine biogeochemical cycles. However, accurate quantification of aerosol deposition onto ocean surfaces remains challenging due to the limited direct observations over oceanic regions. Here, to address this observational gap, we use the cosmogenic radionuclide beryllium-7, measured simultaneously in the atmosp
Background: Occupational balance (OB) is a subjective feeling of having the right amount and variety of occupations. Aims/objectives: The study aims to translate the Occupational Balance Questionnaire (OBQ11) into Chinese (OBQ11-C) and to examine its psychometric properties for people with depression in Taiwan. Material/methods: The OBQ11 was translated and reviewed by 10 experts. Subjects with de
Intensity ratio-based phosphor thermometry is a promising technique for instantaneous temperature measurement of fast-moving objects. However, its accuracy is limited by the blueshift effects of interference filters induced by angle of incidence (AOI) variations. This is especially problematic for phosphors with significant temperature-dependent emission band shifts. To address this issue, we prop
