Low altitude unmanned aerial vehicle (UAV)-aided applications are promising in the future generation communication systems. In this paper, a recently conducted measurement campaign for characterizing the low-altitude air-to-ground (A2G) channel in a typical Long Term Evolution (LTE) network is introduced. Five horizontal flights at the heights of 15, 30, 50, 75, and 100 m are applied, respectively
BACKGROUND: For muscle-invasive bladder cancer (MIBC), no tissue biomarkers are available for clinical use to predict response to neoadjuvant chemotherapy.OBJECTIVE: To investigate how molecular subtypes impact pathological response and survival in patients receiving preoperative cisplatin-based chemotherapy.DESIGN, SETTING, AND PARTICIPANTS: Classification of a retrospective cohort of 149 patient
A microtitre plate based enzyme-linked immunosorbent assay for determining the concentration of serum amyloid A (SAA) is described. The method employs easily produced sequence-specific rabbit antibodies and the preferential absorption of SAA to polystyrene, which obviates the use of capture antibodies and allows an assay time of only 3.5 h, so that the diagnostic potential of the SAA level as a ra
Renal tubular function can be assessed by measuring low molecular weight proteins in urine. In the present study, urinary levels of protein HC, also called alpha 1-microglobulin, were determined in 84 patients, 3-17 years after conduit diversion or continent urinary reconstruction. Increased excretion of protein HC, indicating tubular dysfunction, was found in 30 patients (36%), but was slight in
Objective: The aim of the study was to describe patients’ experience of yoga as a treatment for hypertension, as well as their experience of living with hypertension. Design: Qualitative interview study Method and materials: In 2013–2014, in southern Sweden, patients with hypertension from three health care centres were invited to participate in a randomised controlled trial on yoga for hypertensi
Eugenics and race played significant roles in Ukrainian interwar nationalism, yet remain largely unstudied. The Ukrainian nationalists’ understanding of the racial makeup of their imagined community was contradictory as they struggled to reconcile their desire for racial “purity” with the realities of significant variations between the populations inhabiting the enormous territories which they sou
Purpose: The objective of this study was to compare patients with epiphora and cataract in terms of the activity limitations they experience in daily life due to their visual disability and to validate the use of the Catquest-9SF questionnaire for epiphora patients. Methods: Seventy-two consecutively encountered adult patients with confirmed lacrimal obstruction and listed for dacryocystorhinostom
This article analyses the selection of person reference expressions in narratives in Umpila/Kuuku Ya'u, a Pama-Nyungan language of Cape York Peninsula (Australia). The analysis takes the principle of topic-fittedness, one of a set of design principles proposed to account for the interactional conditioning of person reference formulation, and applies it to Umpila/Kuuku Ya'u narration. The ensuing a
BACKGROUND: Wrist disorders are common in force demanding industrial repetitive work. Visual assessment of force demands have a low reliability, instead surface electromyography (EMG) may be used as part of a risk assessment for work-related wrist disorders. For normalization of EMG recordings, a power grip (hand grip) is often used as maximal voluntary contraction (MVC) of the forearm extensor mu
A solid oxide fuel cell (SOFC) is an electrochemical device that converts energy of a chemical reaction into electrical and thermal energy. Besides lack of pollutants and high electrical efficiency, one of the main advantages of SOFCs is the flexibility of using a wide range of fuels, i.e., natural gas, biogas, or any reactant with hydrogen as constituent. However, the use of hydrocarbon fuels can
Background: Pediatric asthma remains a public health challenge with enormous impact worldwide. Objective: The aim of this study was to identify and prioritize unmet clinical needs in pediatric asthma, which could be used to guide future research and policy activities. Methods: We first identified unmet needs through an open-question survey administered to international experts in pediatric asthma
Background: Intensive care units (ICUs) are hot zones for emergence and spread of antibiotic resistance because of frequent invasive procedures, antibiotic usage and transmission of bacteria. We report prospective data on antibiotic use and bacterial resistance from 14 academic and non-academic ICUs, participating in the ICU-STRAMA programme 1999-2003. Methods: The quantity of antibiotics delivere
Background Renal elimination normally decreases with age. Nonsteroidal antiinflammatory drugs (NSAIDs) carry a risk of additional kidney damage. Objective The aims of this study were to assess the prevalence of NSAIDs in the elderly (aged ≥ 65) population in Sweden, explore reasons for any possible differences in the level of use and assess their kidney functions. Setting Data were obtained from t
Importance: Twin studies have assessed sibling resemblance for major depression (MD) but cannot address sources of resemblance across generations. Objective: To clarify the relative importance of genetic and rearing effects on the parent-offspring resemblance for MD. Design: This Swedish population register-based study examined parents and children from the following 5 family types: intact (2 041
Purpose: The eyelid is commonly dissected and divided in the process of, for example, blepharotomy, entropion repair, or when preparing a full-thickness eyelid flap to reconstruct a tumor defect. No study has yet been conducted to examine how perfusion in an eyelid is affected by dissection, using modern imaging techniques. Methods: The eyelid was divided with a 10-mm vertical incision, 5 mm from
The synchronous firefly genus Pteroptyx Olivier is reassessed from morphological, molecular, and habitat perspectives in Malaysia, and includes some reliably associated females described from morphological features and internal female reproductive anatomy. Phylogenetic analyses using combined morphological and molecular data (where available) for 158 taxa supported all the major features of the ex
Detailed chemical abundance distributions for 14 elements are derived for eight high-probability stellar members of the solar metallicity old open cluster M67 with an age of ∼4 Gyr. The eight stars consist of four pairs, with each pair occupying a distinct phase of stellar evolution: two G dwarfs, two turnoff stars, two G subgiants, and two red clump (RC) K giants. The abundance analysis uses near
