Entrepreneurial education as a scientific field can be regarded as an emerging and growing area of research. In this study we pay particular attention to the community of scholars involved in entrepreneurial education. The aim of the paper is to explore how scholars within the field have integrated into larger scholarly communities. Based on a unique database and web-based responses from 313 entre

We describe the macroscopic behaviour of a particle system with long-range interactions. We describe conditions on the interaction strength in dependency of the distance of the particles, such that the scaling limit of the particle system is a well-posed stochastic PDE.

Electrical impedance tomography (EIT) is a noninvasive imaging modality, where imperceptible currents are applied to the skin and the resulting surface voltages are measured. It has the potential to distinguish between ischaemic and haemorrhagic stroke with a portable and inexpensive device. The image reconstruction relies on an accurate forward model of the experimental setup. Because of the rela

A boundary integral equation is described for the prediction of acoustic propagation from a monofrequency coherent line source in a cutting with impedance boundary conditions onto surrounding flat impedance ground. The problem is stated as a boundary value problem for the Helmholtz equation and is subsequently reformulated as a system of boundary integral equations via Green's theorem. It is shown

A Large Intelligent Surface (LIS) is a recently proposed concept, especially suitable for high speed indoor communications and industrial internet of things (IoT) applications. Basing the LIS on smaller panels has clear advantages in terms of flexibility and mass production of its elements. In this paper we consider a panel-based LIS and we study the interplay of the panel size, the number of base

We study a triangular network of three populations of coupled phase oscillators with identical frequencies. The populations interact nonlocally, in the sense that all oscillators are coupled to one another, but more weakly to those in neighboring populations than to those in their own population. This triangular network is the simplest discretization of a continuous ring of oscillators. Yet it dis

The response of a position-sensitive Li-glass scintillator detector being developed for thermal-neutron detection with 6 mm position resolution has been investigated using collimated beams of thermal neutrons. The detector was moved perpendicularly through the neutron beams in 0.5 to 1.0 mm horizontal and vertical steps. Scintillation was detected in an 8 × 8 pixel multi-anode photomultiplier tube

Healthcare in Sweden is dealing with problems regarding accessibility for patients. Moreover, there is a lack of an overall model concerning matching specialist care to patients. Against this background, the purpose was to develop a preliminary healthcare matching model and discuss the barriers of this model. Theoretically, the study draws on the concepts of matching and coordination completed wit

Purpose: This study was designed to evaluate the performance of typically developing Swedish-speaking children on DYMTA (Dynamisk Motorisk Talbedömning), a Swedish dynamic motor speech assessment. Method: Participants were 94 children, 45 boys/49 girls (9/8 multilingual), with typical oral motor, speech, and language skills, between 37 and 106 months divided into five age-groups. They performed tw

The bromovinyl radical has been prepared by the reaction of bromine atoms with acetylene in an argon matrix at 17 K and its i.r. spectrum has been studied. The spectrum of C2HDBr• shows the presence of two isomers, indicating that the radical has an unsymmetric structure.

The structure of ferroelectric 0.06LiNbO3-0.94K0.5Na0.5NbO3 (KNNL6) was investigated by the neutron total scattering method in the temperature range of 290-773 K. The Rietveld analysis using the powder neutron diffraction data in the range of 290-773 K indicates transition from a two-phase (monoclinic and tetragonal) mixture at room temperature to tetragonal and cubic phases at higher temperatures

BACKGROUND: The Predicting Bleeding Complications in Patients Undergoing Stent Implantation and Subsequent Dual Antiplatelet Therapy (PRECISE-DAPT) score has been shown to predict out-of-hospital major bleeding after myocardial infarction treated with percutaneous coronary intervention and dual antiplatelet therapy (DAPT). However, large validation studies have been scarce and the discriminative a

More than 1 in 7 people in Europe live in a household whose income is below the national poverty line, but more than 30% of people consider themselves to live in poverty. This study provides evidence on the causal relationship between education and various dimensions of poverty. I construct a novel database comprising compulsory schooling reforms in 32 European countries and use them as instrument

Supercritical fluids (e.g., hydrocarbon fuels, water, carbon dioxide, and organic working medium, etc) have been recognized as working media to improve thermal efficiencies in power cycles and energy conversion, and have been used or selected as the working fluids in engineering fields such as aerospace, nuclear power, solar energy, refrigeration, geothermal energy, chemical technology, and so on.

Importance: The incidence of early-onset colorectal cancer (younger than 50 years) is rising globally, the reasons for which are unclear. It appears to represent a unique disease process with different clinical, pathological, and molecular characteristics compared with late-onset colorectal cancer. Data on oncological outcomes are limited, and sensitivity to conventional neoadjuvant and adjuvant t

The matched phase reassignment, developed to estimate phase synchrony of transient oscillatory signals, is extended into a multitaper phase reassignment (MTPR) method. The method gives perfect time-frequency localization for two transients with zero phase difference and estimates of time locations and oscillatory frequencies in low signal-to-noise ratios. For different signal-to-noise ratios betwe

Akin to Zinc Finger and Transcription Activator Like Effector based transcriptional modulators, nuclease-null CRISPR-Cas9 provides a groundbreaking programmable DNA binding platform, begetting an arsenal of targetable regulators for transcriptional and epigenetic perturbation, by either directly tethering, or recruiting, transcription enhancing effectors to either component of the Cas9/guide RNA c
