To investigate the issue of multi-entry bus priority at intersections, an intelligent control method based on deep reinforcement learning was constructed in network environment. Firstly, a dimension reduction for state vector key lane proposed, which contains characteristic parameters such as states, flow and signal timing. Secondly, action that can adjust phase sequence green time same propose...

A fast, two-coil, pseudo-continuous labeling scheme is presented. This new scheme permits the collection of a multislice subtraction pair in <3 s, depending on the subject's arterial transit times. The method consists of acquiring both control and tag images immediately after a labeling period that matches the arterial transit time. The theoretical basis of the technique, and simulations of the...

Buffer Insertion Rings (BIR) are known to provide higher throughputs than other competing ring technologies. With the introduction of spatial reuse, MANs and LANs are at a greater advantage of maximizing bandwidth efficiency. Spatial reuse introduces the concept of congestion and Fairness Algorithms are needed to police the fair access of the low priority traffic on the ring. Two architectures ...

We present an algorithm to solve a deterministic form of a routing problem in delay tolerant networking, in which contact possibilities are known in advance. The algorithm starts with a finite set of contacts with time-varying capacities and transit delays. The output is an optimal schedule assigning messages to edges and times, that respects message priority and minimizes the overall delivery ...

In a transit network involving vehicles with rigid capacities, we advocate the use of strategies for describing consumer behavior. At each boarding node, a user sorts the transit lines in decreasing order of preference, and boards the first vehicle in this list whose residual capacity is nonzero. Since a user’s position in the queue varies from day to day, the delay experienced is stochastic. T...

This paper explores the notion and usefulness of nonstationary velocity profiles for high priority emergency vehicle transit on automated highways. These profiles are intended for use in the link layer of the hierarchical control architecture defined by the California Partners for Automated Transit and Highways (PATH) program. A non-stationary velocity profile which can be used to circulate tra...

Most species of the protozoan phylum Apicomplexa harbor an endosymbiotic organelle--the apicoplast--acquired when an ancestral parasite engulfed a eukaryotic plastid-containing alga. Several hundred proteins are encoded in the parasite nucleus and are posttranslationally targeted to the apicoplast by a distinctive bipartite signal. The N-terminal 20 to 30 amino acids of nucleus-encoded apicopla...
