‎it is well known that every (real or complex) normed linear space $l$ is isometrically embeddable into $c(x)$ for some compact hausdorff space $x$‎. ‎here $x$ is the closed unit ball of $l^*$ (the set of all continuous scalar-valued linear mappings on $l$) endowed with the weak$^*$ topology‎, ‎which is compact by the banach--alaoglu theorem‎. ‎we prove that the compact hausdorff space $x$ can ...

in this paper, we introduce the cone normed spaces and cone bounded linear mappings. among other things, we prove the baire category theorem and the banach--steinhaus theorem in cone normed spaces.

In the present paper, we study some properties of fuzzy norm of linear operators. At first the bounded inverse theorem on fuzzy normed linear spaces is investigated. Then, we prove Hahn Banach theorem, uniform boundedness theorem and closed graph theorem on fuzzy normed linear spaces. Finally the set of all compact operators on these spaces is studied.

Molecular analysis of five Brazilian families, including eight patients presenting with nonclassic Tay-Sachs disease, was performed to identify frequent causative mutations and their correlation with clinical course. Three patients were affected by the B1 subacute variant and were shown to carry the R178H mutation (the DN allele), which is also common among Portuguese patients. Two of them were...

Anterior shoulder instability with Bankart lesion and associated posterior humeral head injury (Hill–Sachs) is common in athletes. Several treatments have been proposed for the management of Hill–Sachs lesion, from bone grafts or rotation osteotomies to capsulotendinous interposition, such as remplissage. This procedure has shown be safe effective increasing glenohumeral stability. However, cor...

BACKGROUND Failed shoulder instability surgery is mostly considered to be the recurrence of shoulder dislocation but subluxation, painful or non-reliable shoulder are also reasons for patient dissatisfaction and should be considered in the notion. METHODS The authors performed a revision of the literature and online contents on evaluation and management of failed shoulder instability surgery....

In a previous letter to the editor, Sachs and Lecar (1991) described a model for gating of mechanosensitive ion channels. This treatment draws on our "gating-spring" model for gating, which involves an elastic element that conveys force to the channel (Corey and Hudspeth, 1983; Howard and Hudspeth, 1988) and extends it to deal with the elasticity of the channel protein itself. The gating-spring...
