Robotics is a growing field that has received tremendous support and focus in recent years. Backed by government and industry interests, robots now have the potential to move beyond traditional manufacturing setting into human-centered environments. Therefore, safety emerges as one of the most fundamental requirements in designing Human-Centered Robots (HCRs). To attain HCRs with high mobility ...

The harmonic mode analysis method was used to characterize the conformational deformability of regular Watson-Crick paired, mismatch- and bulge-containing RNA. Good agreement between atomic Debye-Waller factors derived from x-ray crystallography of a regular RNA oligonucleotide and calculated atomic fluctuations was obtained. Calculated helical coordinate fluctuations showed a small sequence de...

DNA cytosine-rich strands can fold into an intercalated motif (i-motif) structure. The i-motif is formed by mutually intercalated duplexes containing proton-mediated C-H(+)-C (cytosine-proton-cytosine) base pairs. Negatively charged ions of DNA i-motifs produced by electrospray mass spectrometry are therefore zwitterionic if the base pairing motif is preserved in the gas phase. Here we used IRM...

Communication in mobile ad hoc networks (MANET) without having any fixed infrastructure has drawn much attention for research. The infrastructure based cellular architecture sets up base stations to support the node mobility. Thus, mapping the concepts of base stations into MANET could meet its challenges like limited battery power, scalability, available bandwidth etc.. This leads to the desig...

Disability and mobility problems increase with age. Assistive devices such as canes, crutches, and walkers can be used to increase a patient's base of support, improve balance, and increase activity and independence, but they are not without significant musculoskeletal and metabolic demands. Most patients with assistive devices have never been instructed on the proper use and often have devices...

Factor XI is the zymogen of a plasma protease produced primarily in liver that is required for normal blood coagulation. We cloned approximately 2600 base pairs of the human factor XI gene upstream of exon one, identified transcription start sites, and conducted a functional analysis. Luciferase reporter assays demonstrate that the 381 base pairs upstream of exon one are sufficient for maximum ...

Traditional cable robots derive their manipulation capabilities using spooling winches at fixed base locations. In our previous work, we examined enhancing manipulation capabilities of cable robots by the addition of base mobility to spooling winches (allowing a group of mobile robots to cooperatively manipulate a payload using cables). Base mobility facilitated the regulation of the tension-di...

Mobile ad hoc networks (MANETs) consist of mobile devices that form the wireless networks without any fixed infrastructure or centralized administration. The infrastructure based cellular architecture sets up base stations to support the node mobility. Mapping the concepts of base stations into MANET leads to the design of logical clump, where the clump heads in every clump play the role of bas...

An important aspect of any channel assignment algorithm should be balancing the performance of uplink and downlink. Differences in receiver performance, diversity and transmit power used at mobiles and base stations are potential sources of imbalance. In addition, there is a fundamental asymmetry between uplink and downlink interference caused by the locations of mobiles and base statiams. We i...

In their study, Brenna and Spandonaro analyzed the mobility into Italian regions. In particular, it analyzes the situation of 5 regions, with very different backgrounds. With this paper, we try to better define the meaning of health mobility and to find its underlying causes. Furthermore, we propose a strategy that could help in controlling mobility flows that currently are the source of health...
