Metamaterials enable subwavelength tailoring of light–matter interactions, driving fundamental discoveries which fuel novel applications in areas ranging from compressed sensing to quantum engineering. Importantly, the...

Design strategies for improving terahertz (THz) quantum cascade lasers (QCLs) in the 5–6 THz range are investigated numerically and experimentally, with the goal of overcoming the degradation in performance that occu...

InAs/AlSb quantum cascade detectors (QCDs) grown strain-balanced on GaSb substrates are presented. This material system offers intrinsic performance-improving properties, like a low effective electron mass of the well ma...

Driven by satellite remote sensing observations, deep learning models provide a promising solution for the rapid estimation of subsurface thermohaline structures. By learning from large-scale paired surface–subsur...

Optical nanoantennas can efficiently harvest electromagnetic energy from nanoscale space and boost the local radiation to the far field. The dielectric-metal nanogap is a novel design that can help to overcome the core i...

To date, the performance of AlGaN-based mid and deep ultraviolet (UV) light-emitting diodes (LEDs) is limited by the presence of a high density of defects, quantum-confined Stark effect, inefficient doping, and optical p...

We present high time resolution observations of Active Region 8910 obtained simultaneously at 212 and 405 GHz during a large Hα flare, which produced a soft X-ray class X1.1 event. Data were obtained with the new solar ...

Terahertz quantum cascade laser (QCL) sources based on intra-cavity difference frequency generation are currently the only electrically pumped monolithic semiconductor light sources operating at room temperature in the 1...

Photospheric shearing motions are one of the possible ways to inject magnetic helicity into the corona. We explore their efficiency as a function of their particular properties and those of the magnetic field configurati...

Electro-optic modulation is a key function in optical data communication and possible future optical compute engines. The performance of modulators intricately depends on the interaction between the actively modulated ma...

Aims. Bars are considered an efficient mechanism for transporting gas toward the central regions of galaxies and potentially enhance nuclear activity. However, the extent to which bars influence active galactic nuclei (A...

In the recent decade, the EU Member States have been actively implementing the regional development policy based on innovative strategies of smart specialization. However, lately, European researchers have been paying in...

ABSTRACT Background and Aim Cytopenias remain among the most frequent hematologic complications of HIV infection, affecting treatment outcomes and quality of life. The introduction of highly active antiretroviral therapy...

Abstract Social decision-making involves intricate and dynamic interactions between brains, yet prior hyperscanning research primarily concentrated on investigating the overall patterns of interbrain synchrony (IBS), lea...

The events of recent years have shown the need for regional studies. The problems of regionalism have a deep historical retrospective. The Second Polish Republic attempted to change the map of regionalism, in particula...

The line-of-sight magnetograms from Solar Optical Telescope Narrowband Filter Imager observations of NOAA Active Region 10930 have been used to study the evolution of spinning and braiding helicities over a period of fiv...

ABSTRACT The strategies to control the cattle tick, Rhipicephalus microplus are based mainly on the use of synthetic pesticides. However, the emergence, establishment, and development of resistance of ticks is rendering ...

One of the key tasks of the current government is to develop the regions and strengthen their economic potential. One of the most important factors of economic growth is investment. For Ukraine, which is in a crisis pit,...

Abstract Background Baseline data on global research activity on health and human rights (HHR) needs to be assessed and analyzed to identify research gaps and to prioritize funding and research agendas. Therefore, the ai...

Abstract Background In response to the staggering global burden of conditions requiring emergency and essential surgery, the development of international surgical system strengthening (SSS) is fundamental to achieving un...

This study examines the factors that determine whether firms adopt AI and are ready to invest, and explores labour-market and employment-related expectations in wartime Ukraine. Methodology. The study is based on origina...

ABSTRACT OBJECTIVE: To identify factors associated with the acceptability of Covid-19 self-testing among socioeconomically vulnerable populations. METHODS: Cross-sectional study using data from the "TQT Covid-19" proje...
