Selective area growth of cubic gallium nitride is investigated in a plasma assisted molecular beam epitaxy setup. 380 ?m thick silicon (001) and 10 3C-silicon carbide (001), grown on 500 were used as substrates structured with dioxide masks. was tested for both thermal deposited oxides. Multiple series showed that coverage vanished at temperatures 870 °C surface temperature 930 substrates. Wher...

The impact of race on outcomes after carotid artery stenting has not been well elucidated. We therefore examined differences in presentation and perioperative among white, black, Asian patients undergoing (CAS). identified all CAS the Vascular Quality Initiative from 2016 to 2020. compared baseline demographics, comorbidities, characteristics, in-hospital outcomes, 30-day mortality. Multivariab...

We report the synthesis of a room temperature ferromagnetic Mn-Ge system obtained by simple deposition of manganese on Ge(001), heated at relatively high temperature (starting with 250 °C). The samples were characterized by low energy electron diffraction (LEED), scanning tunneling microscopy (STM), high resolution transmission electron microscopy (HRTEM), X-ray photoelectron spectroscopy (XPS)...

Th e conceptual framework of ecostrategies (views and use of landscape) presented here have been used to analyse various cases of nature-based tourism and related activities such as outdoor recreation, outdoor education, nature reserves and conservation. Th e role of the ecostrategies is to illustrate the intersections, confl icts and alliances between diff erent types of nature based tourism a...

Pregnancy is a known risk factor for developing varicose veins (VVs). However, prior studies lacked sufficient size and follow-up to determine the specific characteristics of pregnancy that might influence VV formation. We sought identify which pregnancy-specific factors are associated with development VVs. All women who gave birth from 1998 2020 within multicenter healthcare system were retros...
