Even before the IEEE’s Rail Transit Vehicle Interface Standards Committee (RTVISC) approved IEEE 1473, railcar manufacturers from Breda in Italy to Kinki-Sharyo in Japan to Bombardier in Canada had been designing the underlying LonWorks® protocol into their rail vehicles. But after its formal adoption in 1999, IEEE 1473-L based networks have begun to proliferate at transit properties in North A...

The problem addressed in this document concerns the coordinated allocation of a finite set of reusable resources to a set of concurrently running processes. These processes execute in a staged manner, and each stage requires a different subset of the system resources for its support. Furthermore, processes will hold upon the resources currently allocated to them until they will secure the neces...

Stenting: Where Do They Come From? To the Editor: We read with great interest the study by Sztriha et al1 evaluating the early clinical outcome in a large sample of unprotected carotid artery stenting procedures. Although randomized studies comparing endovascular treatment with endarterectomy are showing encouraging results in favor of the endovascular approach,2,3 cerebrovascular complications...

The incidence of intrahepatic cholangiocarcinoma has been increasing in the last few decades. Interestingly over this period, the incidence of extrahepatic cholangiocarcinoma remained stable. However, the proportion of patients with early stage, small or localized tumors remained the same. This reflects a true increase in the incidence without a corresponding significant gain in our ability to ...

The integrating role that is sought by automation in many contemporary applications frequently can be abstracted to the need for pertinent supervision of a function that allocates a finite set of reusable resources to a set of concurrently executing processes. This article formalizes the corresponding supervisory control problem, surveys the major results that are currently available for it, an...

Objectives: Circulating microRNAs (miRNAs) are promising as biomarkers for various diseases. We examined the release patterns of cardiospecific miRNAs in a closed-chest, large animal ischemia-reperfusion model and in patients with ST elevation myocardial infarction (STEMI). Methods: Six anesthetized pigs were subjected to coronary occlusion-reperfusion. Plasma, urine, and clinical parameters we...

Introduction In September 2022, American retail giant Walmart launched two new gaming experiences onto popular multi-platform experience Roblox, entitled Land and Universe of Play. First released in 2006, Roblox is an online multiplayer programme a virtual world that part rise other similar programmes, including Minecraft (2009), Pokémon GO (2016), Fortnite (2013). Like these games, it also pro...

Following in the footsteps of seminal studies like E. W. Soja Postmetropolis: Critical Studies of Cities and Regions (2000) or Miwon Kwon One Place After Another: Site-specific Art and Locational Identity (2004), this article constitutes a contribution to our current understanding of contemporary societies, more specifically to the shaping of urban identities and the role of contemporary art wh...

The contemporary African city runs on informal modes of public transportation. Typically, minibuses provide the core, but motorbikes, tricycles, and shared taxis all contribute to transport ecosystems. These privately operated services are ground-level responses growing demand for mobility in face absent or inadequate formal transportation services. For many urbanites, it is impossible imagine ...
