Billions of nocturnally migrating songbirds fly across oceans and deserts on their annual journeys. Using multisensor data loggers, we show that great reed warblers (Acrocephalus arundinaceus) regularly prolong their otherwise strictly nocturnal flights into daytime when crossing the Mediterranean Sea and the Sahara Desert. Unexpectedly, when prolonging their flights, they climbed steeply at dawn,
BACKGROUND: Oesophageal cancer management requires extensive in-hospital care. This cohort study aimed to quantify in-hospital care for patients with oesophageal cancer in relation to intended treatment, and to analyse factors associated with risk of spending a large proportion of survival time in hospital. METHODS: All patients with oesophageal cancer in three nationwide registers over a 10-year
Unconventional ferroelectricity exhibited by hafnia-based thin films-robust at nanoscale sizes-presents tremendous opportunities in nanoelectronics. However, the exact nature of polarization switching remains controversial. We investigated a La0.67Sr0.33MnO3/Hf0.5Zr0.5O2 capacitor interfaced with various top electrodes while performing in situ electrical biasing using atomic-resolution microscopy
Most commercial prosthetic hands lack closed-loop feedback, thus, a lot of research has been focusing on implementing sensory feedback systems to provide the user with sensory information during activities of daily living. This study evaluates the possibilities of using a microphone and electrotactile feedback to identify different textures. A condenser microphone was used as a sensor to detect th
Insects constitute a very important part of the global ecosystem and include pollinators, disease vectors, and agricultural pests, all with pivotal influence on society. Monitoring and control of such insects has high priority, and automatic systems are highly desirable. While capture and analysis by biologists constitute the gold standard in insect identification, optical and laser techniques hav
The article concerns the Swedish support system’s legal discourse, and investigates the rationale for excluding people over the age of 65 from services that younger people with disabilities may obtain. Data consist of government texts and court decisions under the Severe Disability Act about services for people over the age of 65. It was found that little in the legal discourse concerns the needs
Peptic Ulcer Disease (PUD) is the most common disorder of the stomach and duodenum, which is associated with Helicobacter pylori infection. PUD occurs due to an imbalance between offensive and defensive factors and Proton Pump Inhibitors (PPI), Nonsteroidal Anti-Inflammatory Drugs (NSAIDs) and antibiotics are frequently used for the treatment. Recently, medicinal plants have emerged as efficacious
BACKGROUND: Recent studies have suggested that artichoke (Cynara scolymus L.) may reduce certain biochemical blood factors but the efficacy of this plant on blood pressure (BP) has not yet been investigated. In this study, we determined the clinical efficacy of C. scolymus on BP and body mass index (BMI) in hypertensive patients as an adjunctive to captopril for the first time.METHODS: The total p
Background: In a European study on contact allergy in the general population, it has been hypothesized that the combination of contact allergy to a fragrance together with a history indicating dermatitis at exposure and thereafter subsequent avoidance of scented products implied a diagnosis of allergic contact dermatitis. Objectives: The primary aim of this study was to validate this hypothesis/al
This study investigates the form of deictic gestures used by speakers of the Quiahije variety of Eastern Chatino (Otomangean, Zapotecan) spoken in Oaxaca, Mexico. An analysis of over six hours of interviews about local landmarks reveals that Quiahije Chatino speakers consistently use the far-is-up strategy to convey target distance in their deictic gestures—the farther the target, the higher and m
Objective: To compare the real-life effectiveness of biologic therapy (a biologic disease-modifying antirheumatic drug plus methotrexate [MTX]) versus triple therapy (MTX plus sulfasalazine plus hydroxychloroquine/chloroquine) for sustained remission of rheumatoid arthritis (RA). Methods: RA patients who were registered in the nationwide Swedish Rheumatology Quality Register between 2000 and 2012
Faults in district heating (DH) customer installations cause high return temperatures, which have a negative impact on both current and future district heating systems. Thus, there is a need to detect and correct these faults soon after they occur to minimize their impact on the system. This paper, therefore, suggests a fault handling process for the detection and elimination of faults in DH custo
In many IoT applications, sensor data is sent remotely to be processed, but only the freshest result is of interest. In this paper we investigate a feedback mechanism that aborts the processing of stale data at the remote end to reduce the load and save costs. The process is approximated by an M/M/$\infty$ queueing system with a feedback loop. We find the exact expression of the average computatioIn many IoT applications, sensor data is sent remotely to be processed, but only the freshest result is of interest.

Background: Continuous monitoring of seasonal influenza vaccine effectiveness (SIVE) is needed due to the changing nature of influenza viruses and it supports the decision on the annual update of vaccine composition. Age-specific SIVE was evaluated against different influenza sub-types in the hospitalized population in Lithuania during four influenza seasons. Methods: A test-negative case-control
Foot measurement is necessary for personalized customization. Nowadays, people usually obtain their foot size by using a ruler or foot scanner. However, there are some disadvantages to this, namely, large measurement error and variance when using rulers, and high price and poor convenience when using a foot scanner. To tackle these problems, we obtain foot parameters by 3D foot reconstruction base
Apolipoprotein E (ApoE), an important mediator of lipid transportation in plasma and the nervous system, plays a large role in diseases such as atherosclerosis and Alzheimer's. The major allele variants ApoE3 and ApoE4 differ only by one amino acid. However, this difference has major consequences for the physiological behaviour of each variant. In this paper, we follow (i) the initial interaction
BACKGROUND: Postoperative pancreatic fistula is the leading cause of morbidity after distal pancreatectomy. Strategies investigated to reduce the incidence have been disappointing. Recent data showed a reduction in postoperative pancreatic fistula with the use of synthetic mesh reinforcement of the staple line. METHODS: An RCT was conducted between May 2014 and February 2016 at four tertiary refer
