TL;DR: This paper presents two mixed integer linear program formulations of a routing model that generalizes existing routing models in the literature and indicates that one of the formulations is very effective in obtaining high quality solutions to real life instances of the problem.

TL;DR: This paper proposes a 3-step mathematical programming based heuristic for the static repositioning problem of bike-sharing systems, and was shown to outperform a previous method suggested in the literature for the same problem.
Abstract: Over the last few years, bike-sharing systems have emerged as a new mode of transportation in a large number of big cities worldwide. This new type of mobility mode is still developing, and many challenges associated with its operation are not well addressed yet. One such major challenge of bike-sharing systems is the need to respond to fluctuating demands for bicycles and for vacant lockers at each station, which directly influences the service level provided to its users. This is done using dedicated repositioning vehicles (light trucks) that are routed through the stations, loading and unloading bicycles to/from them. Performing this operation during the night when the demand in the system is negligible is referred to as the static repositioning problem. In this paper, we propose a 3-step mathematical programming based heuristic for the static repositioning problem. In the first step, stations are clustered according to geographic as well as inventory (of bicycles) considerations. In the second step the repositioning vehicles are routed through the clusters while tentative inventory decisions are made for each individual station. Finally, the original repositioning problem is solved with the restriction that traversal of the repositioning vehicles is allowed only between stations that belong to consecutive clusters according to the routes determined in the previous step, or between stations of the same cluster. In the first step the clusters are formed using a specialized saving heuristic. The last two steps are formulated as Mixed Integer Linear Programs and solved by a commercial solver. The method was tested on instances of up to 200 stations and three repositioning vehicles, and was shown to outperform a previous method suggested in the literature for the same problem.

TL;DR: Avineri et al. as discussed by the authors presented a special review of transport and health in relation to the spread of the Coronavirus Disease Covid-19, which was published in the Journal of Transport & Health.
Abstract: When I took over the editorial duties of Journal of Transport & Health from Professor Jenny Mindell January this year I had not foreseen this first editorial would be written while the world is in such unprecedented state of emergency. To this end, I've asked two Associate Editors of the Journal of Transport & Health, Professor Erel Avineri, Head, Afeka Center for Infrastructure, Transportation and Logistics, Tel-Aviv Academic College of Engineering, and Professor Yusak Susilo, BMK Endowed Professor in Digitalisation and Automation in Transport and Mobility System at the Institute of Transport Studies, the University for Natural Resources and Sciences (BOKU), Vienna, to write a special review of transport and health in relation to the spread of the Coronavirus Disease Covid-19. Following the global outbreak of the Coronavirus Disease (COVID-19) generated by the novel human Coronavirus SARS-CoV-2, countries across the world are taking measures in order to reduce the effects, or at least to slow it down, in order to better cope with public health and better manage its limited resources. Human-to-human transmissions of SARS-CoV-2 have been described with incubation times between 2-10 days, facilitating its spread via droplets, contaminated hands or surfaces (Kampf et al., 2020). While limited knowledge is available about the SARS-CoV-2 virus, we have some experience with other infectious diseases that might have some similar characteristics.

TL;DR: This demonstration represents the first nanotechnology-inspired demonstration on the selective supersensitive detection of explosives, including the nitro- and peroxide-derivatives, on a single electronic platform, and may allow the remote detection of various explosives, a task unachieved by existing detection technologies.
Abstract: The capability to detect traces of explosives sensitively, selectively and rapidly could be of great benefit for applications relating to civilian national security and military needs. Here, we show that, when chemically modified in a multiplexed mode, nanoelectrical devices arrays enable the supersensitive discriminative detection of explosive species. The fingerprinting of explosives is achieved by pattern recognizing the inherent kinetics, and thermodynamics, of interaction between the chemically modified nanosensors array and the molecular analytes under test. This platform allows for the rapid detection of explosives, from air collected samples, down to the parts-per-quadrillion concentration range, and represents the first nanotechnology-inspired demonstration on the selective supersensitive detection of explosives, including the nitro- and peroxide-derivatives, on a single electronic platform. Furthermore, the ultrahigh sensitivity displayed by our platform may allow the remote detection of various explosives, a task unachieved by existing detection technologies.

TL;DR: A numerical study of the role of microcalcifications in plaque vulnerability in an eccentric stenosis model using a transient fluid-structure interaction (FSI) analysis shows that this finding supports the hypothesis that microCalcifications increase the plaque vulnerability.
