In the field of inverse problems, one of the main benefits which can be drawn from primal-dual optimization approaches is that they do not require any linear operator inversion. In addition, they allow to split a convex objective function in a sum of simpler terms which can be dealt with individually either through their proximity operator or through their gradient if they correspond to smooth ...

One of the advantages of video over audio for mediated communication is the ability to transmit non-verbal information. Physical proximity to other people is a form of non-verbal communication that we all employ everyday, although we are barely aware of it. Yet, existing systems for video-mediated communication fail to fully take into account these proxemics aspects of communication. In this pa...

One of the advantages of video over audio for mediated communication is the ability to transmit non-verbal information. Physical proximity between people is a language for non-verbal communication that we all employ everyday, although we are barely aware of it. Yet, existing systems for video-mediated communication fail to fully take into account these proxemics aspects of communication. In thi...

A new class of phenomena discussed in this review is based on interaction between spatially separated, but closely located ferromagnets and superconductors. They are called Ferromagnet-Superconductor Hybrids (FSH). These systems include coupled smooth and textured Ferromagnetic and Superconducting films, magnetic dots, wires etc. The interaction may be provided by the magnetic flux from magneti...

in this paper, using the best proximity theorems for an extensionof brosowski's theorem. we obtain other results on farthest points. finally, wedene the concept of e- farthest points. we shall prove interesting relationshipbetween the -best approximation and the e-farthest points in normed linearspaces (x; ||.||). if z in w is a e-farthest point from an x in x, then z is also a-best ...

pursuit of justice was allowed to overshadow the necessities of the concrete pursuit of justice through the mechanics of a legal system. The same didacticism affected other aspects of the canonical system, albeit not always in as obvious ways. We see it, for instance, in the area of appellate procedure where the canon law seems to show less concern than either the Roman law or the medieval Engl...

Angiotensin II (AII) regulation of renin production by the juxtaglomerular (JG) cells of the kidney is commonly thought to occur through a direct feedback mechanism. However, recent evidence suggests that other cells in the vicinity may indirectly mediate AII's effect on renin production. Therefore we investigated whether an in vitro model of JG cells (As4.1) could have intercellular communicat...

Domains are the evolutionary units that comprise proteins, and most proteins are built from more than one domain. Domains can be shuffled by recombination to create proteins with new arrangements of domains. Using structural domain assignments, we examined the combinations of domains in the proteins of 131 completely sequenced organisms. We found two-domain and three-domain combinations that re...

A patient with Takayasu arteritis with multiple supra-aortic lesions underwent successful treatment with two-staged stent implantation. Stenotic bilateral common carotid, innominate, and left subclavian arteries were dilated, and no restenosis was observed during the follow-up period of 2 years despite recurrent inflammation. Stenting for supra-aortic vessels in cases of Takayasu arteritis has ...

Lipoma arborescens, also known as villous lipomatous transformation of synovium is an unusual fatty lesion of joint. This disorder is characterized by a diffuse increase in the quantity of subsynovial fat in supra-patellar region which bulges the overlying synovial lining and produces a villous architect...
