Heart failure is usually a relentless condition associated with a poor prognosis. Triggered by a physiological insult, maladaptive neurohumoral processes result in an ever-spiralling deterioration of cardiovascular function. However, there are certain underlying conditions which are associated with a temporary reduction in contractile function leading to reversible heart failure. These conditio...

The Geometry of Interaction semantics introduced by Girard provides a new way of understanding the reduction process in the-calculus where the computation steps are linear and reversible. Moreover, this can be trivially implemented to give a simple compilation technique: the Geometry of Interaction Machine. At the cost of introducing global operations (irreversible copying and discarding) Danos...

We present in this paper a fine-grained rollback primitive for the higher-order π-calculus (HOπ), that builds on the reversibility apparatus of reversible HOπ [9]. The definition of a proper semantics for such a primitive is a surprisingly delicate matter because of the potential interferences between concurrent rollbacks. We define in this paper a high-level operational semantics which we prov...

This paper proposes a reversible two dimensional (2D) discrete wavelet transform (DWT) for lossless coding which is compatible with the irreversible 2D 9-7 DWT for lossy coding in the JPEG 2000. Since all the filters and scalings are factorized into a product of lifting steps, and signal values are rounded into integers, the proposed DWT is reversible and applicable to lossless coding of 2D sig...

The present investigation describes for the first time, the synthesis and detailed characterization of a novel fluorescent and amphiphilic chitosan polymer (3) containing fluorescent peryleneimide chromophores for biomedical applications. The polymer 3 is moderately soluble in a wide range of organic solvents and aqueous solutions, unlike chitosan (2). The Mw of 3 and 2 determined by GPC were 4...

The optical properties of metallic nanoparticles are highly sensitive to interparticle distance, giving rise to dramatic but frequently irreversible color changes. By electrochemical modification of individual nanoparticles and nanoparticle pairs, we induced equally dramatic, yet reversible, changes in their optical properties. We achieved plasmon tuning by oxidation-reduction chemistry of Ag-A...

In their description of the isolation and properties of ceruloplasmin, Holmberg and Laurel1 (1) noted that this intensely blue copper-protein could be decolorized by reducing agents such as ascorbic acid. Although the decoloriaation was “. . . completely reversible in the presence of oxygen, attempts to (restore blue color by oxidation) with potassium ferricyanide were not successful.” They won...

bstract. Color transforms are important methods in the analysis nd processing of images. Image color transform and its inverse ransform should be reversible for lossless image processing appliations. However, color conversions are not reversible due to finite recision of the conversion coefficients. To overcome this limitation, eversible color transforms have been developed. Color integer ransf...

The purpose of present study was to evaluate the testes and epididymides mediated reversible contraceptive efficacy of ethanol extract of Tinospora cordifolia stem at the dose level of 400mg/kg. b.wt./rat/day. Oral treatment of 60 days caused significant reduction in number of spermatozoa in cauda epididymides as well as in testis with a decreased in the motility of sperm collected from cauda e...

we present some new results on the existence and the approximationof common fixed point of expansive mappings and semigroups in probabilisticmetric spaces.
