Bandwidth Enhancement of Balanced Folded Loop Antenna Design for Mobile Handsets Using Genetic Algorithms [PDF]
, 2008 YesIn this paper, a simple folded loop antenna (FLA) for handsets with relatively wide- band impedance, designed and optimized using genetic algorithms (GA). The FLA dimensions were optimized and evaluated using GA in collaboration with NEC-2 source code.

Semiclassical dynamics for torsional Newton-Cartan strings
Nuclear Physics B, 2020 We explore folded spinning string configurations over torsional Newton Cartan (TNC) geometry with R×S2 topology within the semiclassical approximation. We consider the large c and/or nonrelativistic (NR) limit associated with the world-sheet d.o.f.

Geography, Environment, Sustainability, 2015 Complicated folded structures were recently recorded by radar survey in the lower portions of the Antarctic and Greenland ice sheets. From a geological point of view the Antarctic and Greenland ice sheets are considered as geological features, while the ...

Planning to fold multiple objects from a single self-folding sheet [PDF]
Robotica, 2011 SUMMARYThis paper considers planning and control algorithms that enable a programmable sheet to realize different shapes by autonomous folding. Prior work on self-reconfiguring machines has considered modular systems in which independent units coordinate with their neighbors to realize a desired shape.

Amyloid oligomer conformation in a group of natively folded proteins. [PDF]
PLoS ONE, 2008 Recent in vitro and in vivo studies suggest that destabilized proteins with defective folding induce aggregation and toxicity in protein-misfolding diseases.

Interaction of β-Sheet Folds with a Gold Surface
PLoS ONE, 2011 The adsorption of proteins on inorganic surfaces is of fundamental biological importance. Further, biomedical and nanotechnological applications increasingly use interfaces between inorganic material and polypeptides. Yet, the underlying adsorption mechanism of polypeptides on surfaces is not well understood and experimentally difficult to analyze ...

Implantation of atelocollagen sheet for vocal fold scar [PDF]
Current Opinion in Otolaryngology & Head & Neck Surgery, 2010 This article reviews recent advances in scaffold-based interventions for the treatment of vocal fold scarring, with a particular emphasis on atelocollagen sheet implantation in the vocal fold lamina propria.Scaffold-based therapies have demonstrated therapeutic promise in both preclinical and early clinical studies.
