In this work terahertz (THz) pulse emission of the non-vertically aligned GaAs core-shell nanowires (NWs) is investigated. THz emission azimuthal dependencies of different NW samples have been measured. It is shown that these measurements together with theoretical calculations could be a very promising method to determine the effective index of refraction (n0) of the NW ensemble. The measurement o

We report on terahertz radiation from topological insulator (TI) Sb2Te3 thin film under ultrafast optical excitation with different helicity. Polarity-reversals of the emitted THz radiation were observed as the helicity of optical pulses reversed. The observed phenomena are coincident with the characteristics of the helicity-dependent photocurrent on TIs. Our work demonstrates the potential applic

A color conversion digital filter is implemented which represents a block of a medical imaging system able to assist gynecologists during colposcopic image analysis is presented. The conceived tool is a monitoring system in the field smart health; in fact an early diagnosis could improve the quality of life and the life expectancy of patients. Tree different digital green filters are conceived and

Proximity and power in collaborative innovation projects. Regional Studies. The proximity literature has so far paid little attention to power relations in collaborative innovation projects. This paper draws on contributions from international business to examine if power constellations between collaborators in innovation projects influence the effects of proximity. An analysis of two cases of col

“Collaboration” is generally portrayed as being beneficial to intelligence and operational police work, even if previous collaborative research shows that conflicts are common between authorities who are supposed to cooperate. The present study focuses on how officers collaborate in their day-to-day management of borderguarding, taking into consideration the different social and cultural backgroun“Collaboration” is generally portrayed as being beneficial to intelligence and operational police work, even if previous collaborative research shows that conflicts are common between authorities who are supposed to cooperate.

With the development of new high-power neutron spallation sources --both for scientific application and as neutron production tool for accelerator-driven systems-- the demand for experimentally obtained nuclear data on the residue nuclei production in the target is constantly increasing. In the present work, we examined two lead-bismuth-eutectic targets, irradiated with high-energy protons, concer

Developmental stress can have organizational effects on suites of physiological, morphological, and behavioral characteristics. In lizards, incubation temperature is perhaps the most significant environmental variable affecting embryonic development. Wall lizards (Podarcis muralis) recently introduced by humans from Italy to England experience stressfully cool incubation conditions, which we here

The Historical Database of Scanian Agriculture (HDSA) is a micro-level database over farm production in the most southern Swedish region of Scania (Skåne) based on flexible tithes. It contains over 85,000 farm level observations of both vegetable and animal production for the period 1702 to 1881. Moreover, this information is supplemented by information on the farmer, the farm, on enclosures, natu

Humanitarian organizations (HOs) often base their warehouse locations on individuals' experience and knowledge rather than on decision-support tools. Many HOs run separate supply chains for emergency response and ongoing operations. Based on reviews of humanitarian network design literature combined with an in-depth case study of United Nations High Commissioner for Refugees (UNHCR), this paper pr

Sharp leading edges with a millimeter-scale radius are required for hypersonic vehicles from aerodynamic reasons. However, with the leading edges being so sharp, stagnation regions at wing and tail leading edges suffer a hostile thermal environment. Therefore, a high-temperature heat pipe is considered to be integrated into the structure of the leading edge to reduce the temperature of the stagnat

Changes in climate are likely to induce changes in precipitation characteristics including intensity, frequency, duration and patterns of events. In this paper, we evaluate the performance of multiple regional climate models (RCMs) in the North American Regional Climate Change Assessment Program (NARCCAP) to simulate storm properties including storm duration, inter-storm period, storm intensity, a

Early detection and differential diagnosis of psychogenicnon-epileptic seizures (PNES) and epileptic seizures (ES) is a majorclinical issue in comprehensive epilepsy centers. Using blind conditionswith patients with PNES (N = 10) and ES (N = 31) before diagnosis,we tested the hypotheses that individuals with PNES would exhibitsignificantly greater dissociativity, hypnotizability, absorption, and h

Semiconductor nanowires are a class of materials recently gaining increasing interest for solar cell applications. In this article we review the development of the field with a special focus on the III-V materials due to their potential to reach high power conversion efficiencies. After introducing basic concepts of nanowire synthesis, we discuss important aspects of nanowire design for high power
