The quality of pedestrian routes of access to a public transport system (PTS) is an important aspect for the choice of transport mode, which can be evaluated using some indicators such as accessibility, comfort, frequency, etc. The policies for urban sustainable mobility must reflect the design and management of mass transit systems, but also the judgment of users in terms of quality and percep...

The usual scenario of service oriented systems is characterized by several services offering the same functionalities, by new services that are continuosly deployed and by other ones that are removed. In this context it can be useful to dynamically discover and compose services at runtime. Orchestration languages provide a mean to deal with service composition, while the problem of fulfilling a...

PURPOSE We proposed to investigate the effects of miR-452-3p on the proliferation and mobility of hepatocellular carcinoma (HCC) cells by targeting cytoplasmic polyadenylation element binding protein 3/estimated glomerular filtration rate (CPEB3/EGFR) axis. METHODS Quantitative real-time polymerase chain reaction (qRT-PCR) was used to detect miR-452-3p expression in 84 pairs of HCC tissues an...

A primary task in wireless sensor networks (WSNs) is data collection. The main objective of this task is to collect sensor readings from sensor fields at predetermined sinks using routing protocols without conducting network processing at intermediate nodes, which have been proved as being inefficient in many research studies using a static sink. The major drawback is that sensor nodes near a d...

Sample pre-concentration can be a critical element to improve sensitivity of integrated microchip assays. In this work a converging Y-inlet microfluidic channel with integrated coplanar electrodes was used to investigate transverse DNA and protein migration under uniform direct current (DC) electric fields to assess the ability to concentrate a sample prior to other enzymatic modifications or c...

the role played by soil constituents in governing temporal trends of metal mobility in calcareousmediterranean soils deserves special attention due to the particular soil and climate characteristics. reactionsoccurring during the aging modify the metal mobility over time, and the rate of metal application and type ofsoil can be decisive in the outcome of aging reactions in soils. the aim of the...

The increasing availability and decreasing cost of mobile devices equipped with WiFi radios has led to increasing demand for multimedia applications in both professional and entertainment contexts. The streaming of multimedia however requires strict adherence to QoS levels in order to guarantee suitable quality for end users. MANETs lack the centralised control, coordination and infrastructure ...

L-selectin (CD62L) amplifies neutrophil capture within the microvasculature at sites of inflammation. Activation by G protein-coupled stimuli or through ligation of L-selectin promotes clustering of L-selectin and serves to increase its adhesiveness, signaling, and colocalization with beta(2)-integrins. Currently, little is known about the molecular process regulating the lateral mobility of L-...
