Introduction: Micrometeorites (MMs) are large (>25 µm) interplanetary dust particles that survive atmospheric entry to be recovered from the Earth's surface. Amongst those particles that escaped significant heating during atmospheric entry two groups have been identified [1]: (i) fine-grained MMs (fgMMs), which are similar to the fine-grained matrices of hy-drated carbonaceous chondrites (CCs),...
UNLABELLED This study evaluates a new formulation of a (99m)Tc-labeled tropane derivate, (99m)Tc-NC100697, in a human volunteer study. METHODS Eighty healthy subjects (39 females, 41 males) underwent MRI and SPECT (injected dose [mean +/- SD], 10.6 +/- 1.4 MBq/kg). Forty subjects were investigated 30, 90, 180, 240, 360, and 480 min after injection, and another 40 subjects were imaged 240 min ...
This paper describes a system for detecting and estimating the properties of multiple travel lanes in an urban road network from calibrated video imagery and laser range data acquired by a moving vehicle. The system operates in several stages on multiple processors, fusing detected road markings, obstacles, and curbs into a stable non-parametric estimate of nearby travel lanes. The system incor...
This article presents the architecture of Junior, a robotic vehicle capable of navigating urban environments autonomously. In doing so, the vehicle is able to select its own routes, perceive and interact with other traffic, and execute various urban driving skills including lane changes, U-turns, parking, and merging into moving traffic. The vehicle successfully finished and won second place in...
The Entrepreneurial Ecosystems (EE) approach makes specific predictions regarding how EE inputs are converted into high-growth firms (HGFs) as an output. A simulation model draws out our hypothesis of regional persistence in HGF shares. Based on intuitions that EEs persistent, we investigate whether shares using census data for 2 European countries taken separately (Croatia 2004–2019, and Slove...
[Purpose] Guidelines and clarity regarding the information for deciding the need for walking sticks and the suitability of these sticks is insufficient. This study aimed to evaluate the suitability of walking stick and its effects on the balance in the elderly. [Subjects and Methods] A total of 39 elderly subjects aged between 65-95 years (mean age, 76.15 ± 8.35 years) and living in the Residen...
