In this issue, “25 Years Ago” revisits the article “Out of Control Because of Harmonics: An Analysis of the Harmonic Response of an Inverter Locomotive,” by Erik Möllerstedt and Bo Bernhardsson, in IEEE Control Systems Magazine, vol. 20, no. 4, pp. 70–81. Below is an excerpt from the article.
This study investigates the neural encoding of speech features in hearing aid users using electroencephalography (EEG) during a simulated cocktail party scenario. The objective was to investigate neural tracking of various acoustic and linguistic features and how hearing aid noise reduction influenced this tracking. The features analyzed included the acoustic envelope, phonetic features, word onse
Begreppet translanguaging (TL) refererade ursprungligen till en pedagogisk praktik som på ett strukturerat sätt involverar två språk (Williams, 1994). I takt med att begreppets innebörd vidgats avsevärt, särskilt under det senaste decenniet, har det också vunnit stort inflytande inom flerspråkighetsforskning, utbildningsvetenskap och relaterade fält. Enligt Mazak (2017) kan TL i dag referera till
In this paper, we speed up robust two-view relative pose from dense correspondences. Previous work has shown that dense matchers can significantly improve both accuracy and robustness in the resulting pose. However, the large number of matches comes with a significantly increased runtime during robust estimation in RANSAC. To avoid this, we propose an efficient match summarization scheme which pro
The authors report a combination of multimodal scanning three-dimensional X-ray diffraction (S3DXRD), X-ray diffraction computed tomography (XRD-CT), and X-ray fluorescence computed tomography (XRF-CT) used for the first time to provide multiscale (spanning the size regime 0.15–500 µm) insight into the aging of a CeO2-ZrO2 solid solution known to exhibit outstanding reversible oxygen storage capac
Rwanda’s Nyabarongo catchment frequently experiences floods, highlighting the need for effective flood susceptibility analysis and management. This study mapped flood susceptibility in the catchment using the random forest (RF), support vector machine (SVM), eXtreme Gradient Boosting (XGBoost), SHapley Additive exPlanations (SHAP) models, as well as various conditioning factors including elevation
Let f be an entire function of finite exponential type less than or equal to σ which is bounded by 1 on the real axis and satisfies f(0)=1. Under these assumptions, Hörmander showed that f cannot decay faster than cos(σx) on the interval (−π/σ,π/σ). We extend this result to the setting of de Branges spaces with cosine replaced by the real part of the associated Hermite–Biehler function. We apply t
Let f be a strictly increasing smooth function, such that f′ is comparable to a weight α′ which is locally doubling and satisfies a non-triviality condition to be explained in the paper. We construct a meromorphic inner function J, such that f−arg(J) is bounded and arg(J)′ is comparable to α′ up to polynomial loss. We give two applications of this result. The first is a sufficient density conditio
We use a lifting trick to show that the Beurling-Malliavin multiplier theorem extends to radial functions in several variables in a straightforward way. This simplifies an argument of Vasilyev and also answers a question of Vasilyev on the Cartwright version of the theorem.
I artikeln presenterar forskarna Tillsammans-projektet, som syftar till att förbättra socialt stöd genom samverkan mellan civilsamhället och vården. Projektet bygger på community connector-modellen, där en samhällskontakt agerar som mellanhand för att koppla patienter till stöttande resurser. Modellen, som utvecklats genom workshops, strävar efter att skapa ett mer omfattande stöd utanför vården, I artikeln presenterar forskarna Tillsammans-projektet, som syftar till att förbättra socialt stöd genom samverkan mellan civilsamhället och vården.

BACKGROUND: The introduction of artificial intelligence (AI) in health care holds great promise, offering the potential to alleviate physicians' workloads and allocate more time for patient interactions. After the emergence of large language models (LLMs), interest in AI has surged in the health care sector, including within primary care. However, patients have expressed concerns about the ethical
Background and Aim. Economic, demographic, and other societal fluctuations leave many buildings vacant due to locational obsolescence. Maximizing the use of existing buildings would foster a shift toward circularity and resource efficiency. This paper explores two lesser known, creative circular strategies for asset and facility management.Methods and Data. Employing futures studies methods, we im
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
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
