We describe the isolation and genetic characterization of point mutations in gene delta, including a temperature-sensitive mutation (del(206)). Genetic methods enable the extraction of a delta mutation from the triple mutant (del,red,gam) and the construction of new genotypes, including del,red and del,gam double mutants. Tests of plating efficiency indicate gene delta is essential for normal p...

delta modeling [6] (ADM) describes the possible ways a product line code base can be structured by delta modeling so that it supports automated product derivation. It puts deltas, which can modify (software) products, into a partial order which restricts their application. If delta x comes earlier in this order than y, then x has to be applied before y. If there is no order between x and y, and...

Conformation changes of the double-stranded DNA helix in response to dehydration were investigated by monitoring, by agarose gel electrophoresis, the linking number of covalently closed circular DNA generated by ligation of linear DNA in the presence of different organic solvents or different temperatures. It was found that: (i) The DNA helix unwinds upon addition of certain organic solvents or...

let a be a unital r-algebra and m be a unital a-bimodule. it is shown that every jordan derivation of the trivial extension of a by m, under some conditions, is the sum of a derivation and an antiderivation.

We introduce a new formal logic, called equality propositional logic. It has two basic connectives, $boldsymbol{wedge}$ (conjunction) and $equiv$ (equivalence). Moreover, the $Rightarrow$ (implication) connective can be derived as $ARightarrow B:=(Aboldsymbol{wedge}B)equiv A$. We formulate the equality propositional logic and demonstrate that the resulting logic has reasonable properties such a...

CWH41 encodes a novel type II integral membrane N-glycoprotein located in the endoplasmic reticulum. Disruption of the CWH41 gene leads to a K1 killer toxin-resistant phenotype and a 50% reduction in the cell wall beta 1,6-glucan level. CWH41 also displays strong genetic interactions with KRE1 and KRE6, two genes known to be involved in the beta 1,6-glucan biosynthetic pathway. The cwh41 delta ...

Renewed attention has been paid to a high order post-Newtonian equation of motion governing inspiralling compact binaries in the context of the efforts for direct detection of gravitational waves [1,2]. It is well-known that detectability of the gravitational waves emitted by the binaries and quality of measurements of astrophysical information (e.g. masses) depend on accuracy of theoretical kn...

Abstract Various leaning method of neural networks including supervised and unsupervised methods are presented and illustrated with examples. General learning rule as a function of the incoming signals is discussed. Other learning rules such as Hebbian learning, perceptron learning, LMS Least Mean Square learning, delta learning, WTA – Winner Take All learning, and PCA Principal Component Analy...
