The sky view factor (SVF) is an important radiometric parameter for assessing the canopy energy budget of urban areas. There are several methods to determine the SVF observationally. The most common is taking a photo with a digital camera equipped with a fish-eye lens and then converting ratio of sky area to canopy area into SVF. However, most urban canopy models use this variable as derived from

Although the number of different types of EVs is increasing, they still constitute only a small share of the total vehicle market. There are a number of barriers to car owners’ adoption of an EV: travel needs, charging infrastructure, the individual car owner’s socio-economic characteristics, attitudinal factors, and environmental concern. In this study, the characteristics and geographic location

Massive MIMO is a compelling wireless access concept that relies on the use of an excess number of base-station antennas, relative to the number of active terminals. This technology is a main component of 5G New Radio and addresses all important requirements of future wireless standards: a great capacity increase, the support of many simultaneous users, and improvement in energy efficiency. Massiv

A search for the exclusive decays of the Higgs and Z bosons to a ϕ or ρ meson and a photon is performed with a pp collision data sample corresponding to an integrated luminosity of up to 35.6 fb−1 collected at s=13 TeV with the ATLAS detector at the CERN Large Hadron Collider. These decays have been suggested as a probe of the Higgs boson couplings to light quarks. No significant excess of events

The transition towards full decarbonisa - tion has reached the political agenda. In September 2016 in Wuppertal, scientists and politicians discussed ways to meet the climate targets.

Pay-per-use business models where consumers pay for the unit of service (e.g. a wash) without gaining product ownership are often linked to increased environmental performance. Consumers would become more conscious about consumption patterns and companies would take responsibility for product life cycle issues. Such benefits can only be achieved when the business model is intentionally designed to

Background and purpose: Pain is highly prevalent in Parkinson's disease (PD), impacting patients’ ability, mood and quality of life. Detecting the presence of pain in its multiple modalities is necessary for adequate personalized management of PD. A 14-item, PD-specific, patient-based questionnaire (the King's Parkinson's Disease Pain Questionnaire, KPPQ) was designed corresponding to the rater-ba

Vocabulary for subsistence and technology may vary a great deal in their degree of borrowability, depending on time, place, inherent subsistence and technology, and the situation of the borrowing. In cross-linguistic typological studies of borrowability, these words tend to group somewhere from middle to high in borrowability, depending on lexical concept (Haspelmath & Tadmor, 2009).We have co

Many individuals with prediabetes, as presently defined, will progress to diabetes (T2D) despite the considerable benefit of lifestyle modification. Therefore, it is paramount to screen individuals at increased risk with a more sensitive method capable of identifying prediabetes at an even earlier time point in the lengthy trajectory to T2D. This petition reviews findings demonstrating that the 1-

Open testicular wedge biopsy has electively been performed prior to completion of maintenance therapy for acute lymphoblastic leukemia. 25 boys during 6 years were included in this prospective study. Three boys developed testicular enlargement while on maintenance therapy and biopsies confirmed testicular leukemia. The remaining 22 boys were biopsied at termination of maintenance therapy. Occult t

A sensitivity analysis on test outcomes from the microscale combustion calorimeter was performed using flexible polyurethane foam as the sample material. Three input factors were investigated: sample preparation, heating rate and pyrolysis chamber atmosphere. The experiments were setup according to the principles of design of experiments and a full factorial design was implemented. In total, 39 ex

The holotype (KUVP 1301) of Styxosaurus snowii—one of the earliest described elasmosaurid plesiosaurians—consists of a well-preserved cranium, mandible and articulated sequence of anterior–mid-series cervical vertebrae found in the lowermost Campanian strata of the Smoky Hill Chalk Member in the Niobrara Formation of Kansas, USA. This particular specimen has proven important for recent phylogenies

During the recent years improved operation techniques and administrative procedures have been developed for early rehabilitation. At the same time preoperative lifestyle intervention (prehabilitation) has revealed a large potential for additional risk reduction. The aim was to assess the quality of life and to estimate the cost-effectiveness of standard care versus an integrated programme includin

A goal of the International Prophylaxis Study Group (IPSG) is to provide an accurate instrument to measure MRI-based disease severity of haemophilic arthropathy at various time points, so that longitudinal changes in disease severity can be identified to support decisions on treatment management. We review and discuss in this paper the evaluative purpose of the IPSG MRI scale in relation to its de

We present calculations on the atomic delay in photoionzation obtained with different combinations of linearly and circularly polarized light, and show how a tensor operator approach can be used to readily obtain results for any combination from a single calculation of the radial integrals. We find that for certain choices of polarization and detection geometry a single time-delay measurement is e

Apart from microhardness and elastic modulus, the stress-strain relation is another important characteristic that more and more scholars have been trying to extract from nanoindentation. With the development of artificial intelligence and computer technology, a machine learning based method is proposed in this paper to extract stress-strain curve of grey cast iron using sharp nanoindentation.
