begin{abstract} If $F,D:Rto R$ are additive mappings which satisfy $F(x^{n}y^{n})=x^nF(y^{n})+y^nD(x^{n})$ for all $x,yin R$. Then, $F$ is a generalized left derivation with associated Jordan left derivation $D$ on $R$. Similar type of result has been done for the other identity forcing to generalized derivation and at last an example has given in support of the theorems. end{abstract}

The argininosuccinate lyase activity of duck delta-crystallin was inactivated by diethyl pyrocarbonate at 0 degrees C and pH 7.5. The inactivation followed pseudo-first-order kinetics after appropriate correction for the decomposition of the reagent during the modification period. The plot of the observed pseudo-first-order rate constant versus diethyl pyrocarbonate concentration in the range o...

Nowadays the electronic gadgets have been updated to store large amount of music information. It is necessary to have an efficient retrieval system to choose the required data. The important task in audio retrieval system is feature extraction. In the feature extraction stage, the feature which gives relevant information about music has to be extracted. In this paper, various Mel based feature ...

Appropriate bias is widely viewed as the key to e cient learning and generalization I present a new algorithm the Incremental Delta Bar Delta IDBD algorithm for the learning of appropri ate biases based on previous learning experience The IDBD algorithm is developed for the case of a simple linear learning system the LMS or delta rule with a separate learning rate parameter for each input The I...

In this paper, we use integral equations of non-integer orders to derive discrete maps with memory. Note that memory were not previously derived from fractional orders. Such a derivation is proposed for the first time in work. nonlocality and exact solutions Riemann–Liouville Hadamard type integrals periodic sequence kicks are described by Dirac delta-functions. The suggested these without any ...

Aquilegia vulgaris seed oil contains high levels of the rare fatty acid columbinic acid (18:3 Delta(5,9,12)), which is unusual in having the double bond at the Delta(5) carbon in the trans configuration. Columbinic acid was found to be a seed-specific fatty acid not only present in the storage oil but also in membrane lipids. Several putative gene fragments have been isolated from plant RNA wit...

Appropriate bias is widely viewed as the key to eecient learning and generalization. I present a new algorithm, the Incremental Delta-Bar-Delta (IDBD) algorithm, for the learning of appropriate biases based on previous learning experience. The IDBD algorithm is developed for the case of a simple, linear learning system|the LMS or delta rule with a separate learning-rate parameter for each input...

Nonvertebrate model hosts represent valuable tools for the study of host-pathogen interactions because they facilitate the identification of bacterial virulence factors and allow the discovery of novel components involved in host innate immune responses. In this report, we determined that the greater wax moth caterpillar Galleria mellonella is a convenient nonmammalian model host for study of t...

Past work has shown that a subset of effector T cells with unique characteristics could abrogate hapten- or antigen-induced tolerance, and the reconstitution of this immune response has been termed contrasuppression. We have studied contrasuppression in a model of oral tolerance (OT) in which adoptively transferred antigen-specific T contrasuppressor (Tcs) cells reverse OT and result in antibod...

Hepatitis delta virus (HDV) is a distant relative of plant viroids in the animal world. Similar to plant viroids, HDV replicates its circular RNA genome using a double rolling-circle mechanism. Nevertheless, the production of hepatitis delta antigen (HDAg), which is indispensible for HDV replication, is a unique feature distinct from plant viroids, which do not encode any protein. Here the HDV ...
