This paper proposes an alternative semi-analytical Fourier modal method adapted for general periodic anisotropic gratings made of dielectrics with moderate to low index profiles corresponding to materials ranging from conventional dielectric 3D printing materials to ceramic materials. The proposed method is closely related to the classical rigorous coupled wave analysis built on scattering matrice
Voice problems are common among workers in occupations with high demands on oral communication. For sustaining vocal health, it is important to find efficient ways for how to reduce strain on the voice at work, and one way to do so is optimizing the room acoustics for communication. However, to date we do not know enough about what kind of room acoustic conditions that support voice and speech mos
We consider the problem of reconstructing the sound field in a room using prior information of the boundary geometry, represented as a point cloud. In general, when no boundary information is available, an accurate sound field reconstruction over a large spatial region and at high frequencies requires numerous microphone measurements. On the other hand, if all geometrical and acoustical aspects of
A measurement of off-shell Higgs boson production in the H∗ → ZZ → 4ℓ decay channel is presented. The measurement uses 140 fb−1 of proton–proton collisions at √s = 13 TeV collected by the ATLAS detector at the Large Hadron Collider and supersedes the previous result in this decay channel using the same dataset. The data analysis is performed using a neural simulation-based inference method, which
The instability of perovskite interfaces caused by interfacial defects and heterojunction evolution hinders the realization of long-term stable inverse perovskite solar cells (IPSCs). This work reports a strategy for the study of heterojunction evolution, the effects of buried interface and carrier dynamics on the stability of perovskite films and devices in 2D/3D heterojunctions. The emphasis is
In this paper, we consider near-field localization and sensing with an extremely large aperture array under partial blockage of array antennas, where spherical wavefront and spatial non-stationarity are accounted for. We propose an Ising model to characterize the clustered sparsity feature of the blockage pattern, develop an algorithm based on alternating optimization for joint channel parameter e
In this Letter, the first evidence of the (Formula presented) antihypernucleus is presented, along with the first measurement at the LHC of the production of (anti)hypernuclei with mass number (Formula presented), specifically (Formula presented) and (Formula presented). In addition, the antiparticle-to-particle ratios for both hypernuclei ((Formula presented) and (Formula presented)) are shown, w
This paper proposes a high-precision self-sensing method for piezoelectric actuators using a hybrid neural network that integrates complex permittivity information. The proposed method addresses the limitations of conventional permittivity-based self-sensing, which typically exhibits approximately 1% remaining hysteresis. A knowledge-based polynomial model is first employed to capture the primary
Wetting and dewetting dynamics in aqueous solutions containing amphiphilic compounds involve intricate interactions that influence contact angles and surface tension, with broad implications in materials science and biology. This study explores the dynamics of wetting and dewetting on glass surfaces in aqueous media containing the amphiphilic compound C18OE84, focusing on capillary rise behavior.
This paper examines forest-based bioeconomy innovation in Sweden between 1970 and 2021 to test central claims about innovation complexity, knowledge requirements, collaboration intensity, and industrial life cycle dynamics. Using a comprehensive database of 4,972 commercialized innovations, I identify 649 forest bioeconomy innovations and analyze their characteristics through logistic regression,
Hydrogen transfer reactions hold pivotal importance in organic synthesis by enabling selective bond formation, achieving redox-neutral transformations, and advancing sustainable methodologies. However, designing efficient catalytic systems for such reactions under mild conditions persists as a fundamental challenge in green chemistry. In this study, we present a controllable synthesis of defective
Background: In patients resuscitated after cardiac arrest, a higher mean arterial pressure (MAP) may increase cerebral perfusion and attenuate hypoxic brain injury. Here we present the protocol of the mean arterial pressure after cardiac arrest and resuscitation (MAP-CARE) trial aiming to investigate the influence of MAP targets on patient outcomes. Methods: MAP-CARE is one component of the Sedati
The reassignment technique is used to increase localization for signal components in the time-frequency representation. The technique gives perfect localization for linear chirp signals and constant frequency signals. Despite the recent interest in using the reassignment technique to determine phase-shifts, no general expression of cross-spectrogram reassignment vectors exists. This submission aim
Why are some regions rich and others poor? This study investigates the geographical origins of Italy’s persistent regional income gap. Using municipal population density as both a proxy for historical income and an outcome shaped by geography, we show that first-nature advantages, such as mild climates and fertile soils, predict higher population density in Northern Italy from the earliest availab
Deception jamming is a powerful technique used to disrupt various radar systems. In this work, we propose a novel sensor selection scheme for FDA-MIMO radar systems designed to maximize the likelihood of accurate jammer identification. The approach exploits the inherent delay between a jammer measuring incoming waveforms and its response. This delay induces a slight shift in the perceived distance
Bekämpningen av penningtvätt utgör ett centralt samhällsintresse inom Europeiska unionen och har gett upphov till ett omfattande regelverk som ställer långtgående krav på att verksamhetsutövare behandlar och lagrar personuppgifter. Samtidigt har skyddet för den personliga integriteten stärkts genom EU:s allmänna dataskyddsförordning (GDPR). Regelverken är inte direkt motstridiga, men förutsätter eThe fight against money laundering constitutes a central public interest within the European Union and has resulted in an extensive regulatory framework imposing far-reaching obligations on obliged entities to process and retain personal data. At the same time, the protection of personal privacy has been strengthened through the EU General Data Protection Regulation (GDPR). Although these regulato
Circulating levels of the astrocytic marker S100B have been associated with risk of neuropsychiatric or neurological disorders. However, reported effects have been inconsistent, and no causal relations have yet been established. We applied two-sample Mendelian Randomization (MR) on the association statistics from genome-wide association studies (GWAS) for circulating S100B levels measured 5-7 days
Background and purpose: Stereotactic radiosurgery (SRS) requires high positional accuracy to safely deliver large doses. This study evaluated an integrated surface- and image-guided radiotherapy (SGRT-IGRT) system by analysing (1) the agreement between thermo-optical and stereoscopic X-ray positioning, and (2) the impact of intra-fractional workflows on treatment accuracy and time. Materials and m
Background: Stereotactic body radiotherapy (SBRT) is an established treatment for previously unirradiated spinal metastases; however, the literature is limited with respect to SBRT as a re-irradiation salvage therapy. We performed a systematic review and meta-analysis as basis for joint ESTRO-ISRS clinical practice recommendations of salvage SBRT for spinal metastases. Methods: A systematic review
Heart failure (HF) is a major contributor to global morbidity and mortality. While distinct clinical subtypes, defined by etiology and left ventricular ejection fraction, are well recognized, their genetic determinants remain inadequately understood. In this study, we report a genome-wide association study of HF and its subtypes in a sample of 1.9 million individuals. A total of 153,174 individual
