The 2018 drought was one of the worst European droughts of the twenty-first century in terms of its severity, extent and duration. The effects of the drought could be seen in a reduction in harvest yields in parts of Europe, as well as an unprecedented browning of vegetation in summer. Here, we quantify the effect of the drought on net ecosystem exchange (NEE) using five independent regional atmos

Background: To target specific neuronal populations by gene transfer is challenging. A complicating fact is that populations of neurons may have opposing roles despite being found adjacent to each other. One example is the medium spiny neurons of the striatum. These cells have different projection patterns, a trait used in this study to specifically target one population. New Method: Here we prese

De stora miljö- och samhällsproblemen kommer inte ensamma. De är sammankopplade på olika sätt. Detta innebär utmaningar men ger också möjligheter att utveckla åtgärder och lösningar. Det gäller både för klimatfrågan och frågan om att motverka förlusten av biologisk mångfald och ekosystem. Kunskapens betydelse för att hantera dessa och andra aspekter är ovärderlig, såväl kring specifika frågeställn

Background Breathlessness is a major cause of physical limitation. Recalled breathlessness intensity may differ from experienced intensity and be influenced by the intensity trajectory including the ‘peak-end rule’. The primary aim was to test if adding two minutes of low intensity exercise at the end of an exercise test would change the recalled breathlessness. Secondary aims included to analyse

Deep learning has proven itself to be a powerful tool to develop datadriven signal processing algorithms for challenging engineering problems. By learning the key features and characteristics of the input signals instead of requiring a human to first identify and model them, learned algorithms can beat many human-made algorithms. In particular, deep neural networks are capable of learning the comp

We investigated fluoride (F−) concentration and physicochemical features of groundwater in the Urmia coastal aquifer (northwest, Iran). Groundwater samples were collected during both dry (58 wells) and wet seasons (84 wells). Approximately 15 and 23% of the groundwater samples in the dry and wet seasons, respectively, exceeded the recommended F− value by WHO for drinking water (1.5 mg/L). High F−

This article analyzes divisions within Belarusian protest communities byfocusing on a particular group: the professional protesters. In Belarus, this group occupies a crucial position in between the international structures of democracy promotion and the internal attempts of political mobilization against the politics of President Aliaksandr Lukashenka. Performativity as an analytical perspective

Recent data suggest that heat pumps, despite having the potential to cover over 90% of the global space and water heating demands, only provide less than 5% of global heating. Heat pumps, in general, and ground source heat pumps, specifically, offer significant potential for energy savings and carbon emissions reduction in buildings. The realization of these potential benefits, however, requires p

Locomotion control in mammals has been hypothesized to be governed by a central pattern generator (CPG) located in the circuitry of the spinal cord. The most common model of the CPG is the half center model, where two pools of neurons generate alternating, oscillatory activity. In this model, the pools reciprocally inhibit each other ensuring alternating activity. There is experimental support for

Chlorophyll is the light-harvesting molecule central to the process of photosynthesis. Chlorophyll is synthesized through 15 enzymatic steps. Most of the reactions have been characterized using recombinant proteins. One exception is the formation of the isocyclic E-ring characteristic of chlorophylls. This reaction is catalyzed by the Mg-protoporphyrin IX monomethyl ester cyclase encoded by Xantha

Background: Giant cell arteritis (GCA; sometimes referred to as temporal arteritis) and polymyalgia rheumatica (PMR) are common and interrelated inflammatory conditions that almost exclusively affect adults older than 50 years. There is a need for updated information on the epidemiology of these diseases. Objective: This systematic literature review (SLR) aims to summarize current evidence regardi

Despite medical, technical, and pedagogical advances, the risk for language impairment is still much higher in deaf and hard-of-hearing (DHH) children than in hearing peers. Research on linguistic, cognitive, and communicative development in DHH children has found a range of basic spoken language deficits. Twenty percent to 50% of deaf children still meet criteria for language impairment. Tests of

Background: The present study aimed to examine the reliability and validity of the Italian version of the Autism Spectrum Disorder in Adults Screening Questionnaire (ASDASQ), a screening tool for autism spectrum disorder (ASD) among psychiatric outpatients. Methods: We recruited 340 subjects via an outpatient psychiatric service in Italy. Forty-eight had a diagnosis of ASD, confirmed after a compr

This paper discusses the COVID-19 pandemic as an opportunity to reconsider the foundations of the global aviation system. There is much evidence that air transport creates opportunities as well as risks. While the former accrue to businesses and individuals, risks are imposed on society. Pandemics, in which aviation has a role as a vector of pathogen distribution, as well as the sector's contribut
