This paper assesses whether multi-path communication can help latency-sensitive applications to satisfy the requirements of their users. We consider Concurrent Multi-path Transfer for SCTP (CMT-SCTP) and Multi-path TCP (MPTCP) and evaluate their proficiency in transporting video, gaming, and web traffic over combinations of WLAN and 3G interfaces. To ensure the validity of our evaluation, sever...

Rhizobium tropici forms nitrogen-fixing nodules on the roots of the common bean (Phaseolus vulgaris). Like other legume-Rhizobium symbioses, the bean-R. tropici association is sensitive to the availability of phosphate (P(i)). To better understand phosphorus movement between the bacteroid and the host plant, P(i) transport was characterized in R. tropici. We observed two P(i) transport systems,...

Cultured human choriocarcinoma (BeWo) cells have previously been shown to exhibit, in comparison with other cultured cell types, elevated nitrobenzylthioinosine (NBMPR)-sensitive transport activity and large numbers (> 10(7)/cell) of high-affinity NBMPR-binding sites [Boumah, Hogue and Cass (1992) Biochem. J. 288, 987-996]. The present study investigates whether NBMPR-sensitive nucleoside trans...

OBJECTIVE The Dahl salt-sensitive rat is a well-established model of salt-sensitive hypertension. The goal of this study was to assess the expression and activity of renal sodium channels and transporters in the renin-deficient salt-sensitive rat. METHODS Renin knockout (Ren(-/-)) rats created on the salt-sensitive rat background were used to investigate the role of renin in the regulation of...

We propose and demonstrate an Ethernet transport system that can support hard real-time traffics with guaranteed throughput and very low jitter performance even in the presence of asynchronous traffics. The superframe structure-based Ethernet system first synchronizes all the nodes in a network by using the IEEE 1588-compliant boundary clock scheme and then reserves the traffic channels for syn...

Printed nanocomposites are of significant application potential in numerous technologies, such as touch-sensitive sensors and surfaces. Here, temperature dependent electrical transport measurements were undertaken on a recently developed screen-printed, multicomponent, nanocomposite ink to develop a detailed understanding of the electrical transport mechanisms. A theoretical model combining con...

To study and define the early time-dependent response (≤6 h) of blocker-sensitive epithelial Na+channels (ENaCs) to stimulation of Na+ transport by aldosterone, we used a new modified method of blocker-induced noise analysis to determine the changes of single-channel current ( i Na) channel open probability ( P o), and channel density ( N T) under transient conditions of transport as measured b...

Bovine retinal pigment epithelium (RPE)-choroid explants were sealed in an Ussing chamber. Typical preparations produced a transepithelial voltage (Ve) of 12 mV (retina side positive) and had an electrical resistance (R) of 300 ohm-cm2. These values can be attributed to the RPE. Furosemide and ouabain reduced the Ve without affecting R when applied to the apical side of the RPE, but had no effe...
