Objectives Critically ill COVID-19 patients admitted to the intensive care unit (ICU) are at an increased risk of acquiring bacterial bloodstream infections (BSI). We aimed to describe patient characteristics, risk factors, and the microbiological spectrum in blood cultures and evaluate the impact of ICU-acquired BSI on outcomes in a Nordic setting. Methods A prospective multicenter cohort study w

Carefully selecting the source data is crucial to achieve high performance of transfer learning methods for brain–computer interfaces (BCIs). Especially so in settings where a large amount of source data is available, and finding the optimal source is not computationally feasible. This paper presents a novel method for source selection, the so-called Transfer Performance Predictor (TPP) method. Th

INTRODUCTION: Resection of intraductal papillary mucinous neoplasm (IPMN) aims to prevent progression to invasive pancreatic cancer. However, the risks of pancreatic surgery and frequent findings of low-grade dysplasia (LGD) raise concerns about overtreatment. This EAHPBA-endorsed multinational study evaluated short- and long-term overall survival (OS) following preventive resection for IPMN (with

Future wireless communications will rely on multiple-input multiple-output (MIMO) beamforming operating at millimeter wave (mmWave) frequency bands to deliver high data rates. To support flexible spatial processing and meet the demands of latency-critical applications, it is essential to use fully digital mmWave MIMO beamforming, which relies on accurate channel estimation. However, ensuring power

Disclosed is a method (310) for providing operational feedback during power transfer in a wireless power transfer system. The wireless power transfer system comprises a power transmit device arranged to transfer power over an inductive wireless power transfer interface operating at a transmit frequency to a power receive device. The wireless power transfer system is adapted to transfer information

The healthcare systems of today are facing large challenges, with increasing amounts of patients and overworked hospital staff.Prostate cancer and Alzheimer’s disease are two of the most prevalent diseases, with incidence numbers expected to rise over thecoming decade. Medical imaging plays a central role in current diagnostic procedures for these diseases, enabling the potentialuse of machine-lea

In this paper, we propose the design of a roof-glass integrated microstrip antenna for vehicular SDARS tuners. The proposed microstrip antenna is sandwiched inside a multi-layer roof glass and uses a solar-heat reduction coating on the bottom side of the glass as ground plane. To offset the effect of the lossy glass, parasitic elements are added to enhance the antenna gain. Simulation results show

The unquenchable thirst for bandwidth to support next-generation wireless systems is increasingly bringing D-band into the spotlight. This work proposes a scalable D-band patch antenna that features both coplanar and stacked parasitic patch structures. By leveraging inter-patch coupling, different coplanar parasitic elements are excited across different frequency bands, enabling multi-mode operati

Although 6G is not only about higher data rates, its envisioned peak data rate of 1 terabits per second requires larger frequency bandwidth than what 5G millimeter wave bands offer. Therefore, new frequency bands have been allocated in the sub-THz range for 6G applications. This paper reviews the concept of distributed deployment to provide coverage in sub-THz bands, focusing on the design and imp

The Artificial Intelligence (AI) Act is a relatively new regulation set out in the European Union (EU). It lays out various requirements for AI systems that are placed on the market in the EU. This paper provides a critical and differentiated view of its requirements from a software engineering perspective. A detailed analysis of the legal document shows what requirements are set out for different

This paper addresses the time-optimal path-tracking problem for redundant manipulators. By integrating path-velocity control into existing task-space robot controllers, the task-space motion can be dynamically scaled to satisfy the torque constraint under both kinematic and dynamic uncertainties. Numerical simulations and experiments demonstrate that trajectory feasibility and path-tracking accura

Software analytics (SA) is often proposed as a tool to support software engineering (SE) tasks. Several secondary studies on SA have been published, some published within the same calendar year. This presents an opportunity to take a meta-perspective and examine how the field of SA has been conceptualized and synthesized so far. By analyzing how SA is defined, which topics are emphasized, what sea

Full-duplex (FD) communication improves spectral efficiency by allowing simultaneous transmission and reception on the same frequency band. This paper analyzes a two-tier network consisting of macrocells and picocells, where base stations (BSs) operate in FD mode while users operate in half-duplex (HD) mode. However, interference remains a major challenge in these systems, significantly impacting

Massive multiple input, multiple output (MIMO) systems are crucial for enhancing spectral efficiency and link reliability in next-generation wireless communications. However, high Peak-to-Average Power Ratio (PAPR) remains a significant challenge, leading to power inefficiencies and signal distortion. This paper presents a low complexity method for PAPR reduction using hard clipping tailored for f

Bridge monitoring is essential for ensuring their long-term safety, reducing disruptions, and supporting economic and social activities. Traditional monitoring techniques rely on periodic inspections and contact-based sensing systems, which, while effective, have limitations due especially to high installation and maintenance costs. Satellite-based Synthetic Aperture Radar Interferometry (InSAR) o

Histatins are a family of multifunctional, cationic histidine-rich saliva peptides. The most prominently represented are Histatin 1, Histatin 3, and Histatin 5. Despite considerable similarities in primary structure, the three members are known to display varied antimicrobial properties and healing abilities. This study aims to provide a detailed structural comparison of Histatin 1, Histatin 3, an

This paper addresses the path-tracking problem of time-optimal trajectories under model uncertainties, by proposing a real-time predictive scaling algorithm. The algorithm is formulated as a convex optimization problem, designed to balance the trade-off between improving feasibility and time optimality of a trajectory. The predicted trajectory is scaled based on the presence of path segments that

Introduction: Extrauterine pregnancy (EP), represents a significant challenge in reproductive medicine, manifesting in approximately 2% of all pregnancies, primarily implanting within the fallopian tubes (95%). Surgery remains a cornerstone in the therapeutic options for ectopic pregnancies. The most common surgical approach at the moment is laparoscopy. However a relatively new surgical technique
