Monitoring, predicting and understanding tra c conditions in a city is an important problem for city planning and environmental monitoring. GPS-equipped taxis can be viewed as pervasive sensors and the large-scale digital traces produced allow us to have a unique view of the underlying dynamics of a city’s road network. In this paper, we propose a method to construct a model of tra c density ba...

The fatty acid composition of farmed Tra catfish (Pangasius hypophthalmus) was determined and compared to farmed Atlantic salmon (Salmo solar) and to wild-caught Asian seabass (Lates calcarifer). Saturated fatty acids (SFA) were most abundant in catfish (42.6%) while salmon (37.2%) and seabass (39.0%) were rich in polyunsaturated fatty acids (PUFA). Tra catfish contains Docosahexaenoic acid (DH...

In this paper we study a queueing model with a server that changes its service rate according to a nite birth and death process. The object of interest is the simultaneous distribution of the number of customers in the system and the state of the server in steady-state. The model can be applied to the performance analysis of (low priority) Available Bit Rate (ABR) tra c at an ATM switch in the ...

The present study indicated the successful construction of a silica nanoparticle (SLN)-based drug delivery system (DDS) for the tumor-targeted co-delivery of two anti-angiogenic drugs, candesartan (CD) and trastuzumab (Tra), for ovarian cancer therapy via different anti-angiogenic mechanisms using hyaluronic acid (HA)/Tra/CD/SLNs. In vitro and in vivo anti-angiogenic assays indicated that CD an...

The tra c generated by multimedia applications presents a high degree of burstiness that can hardly be described by a static set of tra c parameters. We present a dynamic QoS negotiation scheme applied to a prototype application that provides temporized data transfer. The dynamic and e cient usage of the resources can be reached with the introduction of the renegotiable variable bit rate (RVBR)...

Predicted air tra c growth is expected to double the number of ights over the next 20 years. If current means of air tra c control are maintained, airspace capacity will reach its limits. The need for increasing airspace capacity motivates improved aircraft trajectory planning in 4D (space+time). In order to generate sets of con ict-free 4D trajectories, we introduce a new nature-inspired algor...

With the increasing use of clusters in real-time applications, it has become essential to design high performance networks with Quality-of-Service (QoS) guarantees. In this paper, we explore the feasibility of providing QoS in wormhole switched routers, which are widely used in designing scalable, high performance cluster interconnects. In particular, we are interested in supporting multimedia ...

The Drosophila doublesex female-specific splicing enhancer consists of two classes of regulatory elements, six 13-nucleotide repeat sequences, and a single purine-rich element (PRE). Here, we show that the Drosophila regulatory proteins Transformer (Tra) and Transformer 2 (Tra2) recruit different members of the SR family of splicing factors to the repeats and the PRE. The complexes formed on th...

[Purpose] This study examined the effects of closed chain exercises performed with local vibration applied to an unstable support surface on the thickness and length of the transverse abdominis. [Subjects] The subjects were 64 healthy university students who were randomly assigned to a bridge exercise with sling and vibration group (BESVG, n=30) and a bridge exercise with sling group (BESG, n=3...

In order to ensure continued availability of high-performance network for the nation's research and education community and to continue supporting the development of new high performance Internet capabilities, the National Science Foundation (NSF) established the very-high-speed Backbone Network Service (vBNS) through a cooperative agreement with MCI telecommunications Corporation. To ensure qu...
