The advances in highly automated and autonomous transportation systems over the last decade have generated great interest in topics in the safe navigation of land vehicles. With distributed control strategies employed in the majority of applications of autonomous vehicles, such as traffic and formation control, the much-required resilience takes the form of fault-tolerance with respect to informat
Robotic systems for manipulation tasks are increasingly expected to be easy to configure for new tasks. While in the past, robot programs were often written statically and tuned manually, the current, faster transition times call for robust, modular and interpretable solutions that also allow a robotic system to learn how to perform a task. We propose the method Behavior-based Bayesian Optimizatio
The rise of 5G technology leads to a boom in the demand for widely available wireless connectivity while requiring telecommunication networks to improve spectral efficiency and deploy dynamic spectrum sharing (DSS) and carrier aggregation (CA). This imposes more stringent intermodulation test scenarios and blocking requirements on RF transceivers. In addition, they are required to be programmable
Aim: The aim of the study was to deepen the current knowledge of how patients with chronic obstructive pulmonary disease and long-term oxygen treatment think about and expect end-of-life. Design: A qualitative design was used. Methods: A purposeful sample of 19 patients with oxygen-dependent chronic obstructive pulmonary disease was obtained from the Swedish National Registry on Respiratory Failur
A wideband balun-LNA featuring common gate (CG) – common source (CS) noise cancelling, current reuse, and g0.8 GHz to 7.3 GHz that fulfills the requirements of sub-6 GHzm -boosting is presented. It covers frequency range from 5G new radio (NR) technology. The LNA provides balanced output for identical differential loads and employs forward body biasing for linearity improvement. The LNA has low se
Critical infrastructures provide essential services for the functioning of the society, and vulnerability analysis is an important basis for decisions concerning increasing their robustness against strains. Since critical infrastructures can be regarded as complex systems, such analyses can prove challenging. To analyze the system response to strains, several different functional models have been
ConspectusThe photophysics and photochemistry of transition metal complexes (TMCs) has long been a hot field of interdisciplinary research. Rich metal-based redox processes, together with a high variety in electronic configurations and excited-state dynamics, have rendered TMCs excellent candidates for interconversion between light, chemical, and electrical energies in intramolecular, supramolecul
Oily wastewater presents a serious environmental challenge, demanding sustainable and regenerative membrane technologies. Here, we report a green and scalable method for fabricating skin-replaceable cellulose membranes (SRC-M) from jute agro-waste, using a NaOH/urea activation route and argon-pressurized deposition onto ceramic supports. The resulting Cellulose II-based asymmetric membranes exhibi
This paper presents a novel low-profile, single-layer, differentially-fed microstrip antenna with a flat-top beam (FTB). By incorporating a central hexagonal slot together with four elongated slots and two short slots, the proposed antenna tailors high-order modes to achieve the desired radiation characteristics. By analyzing the electric field, the distribution in various regions is decomposed an
Discovering topological quantum materials that combine nontrivial topology with large bandgaps and experimentally accessible signatures remains a central pursuit in condensed matter physics. We demonstrate, through first-principles calculations and tight-binding modeling, that pyrite-type osmium disulfide (OsS2) is a fragile topological insulator (FTI) characterized by an exceptionally large direc
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
When discussing the relationship between religion and LGBTQIA+ rights in Europe today, the two are often framed by both religious and secular representatives as oppositional forces. While the rights of sexual and gender minorities are frequently described as symbols of progress and modernity within liberal democracies, religious communities and traditions are commonly portrayed as defenders of tra
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
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
