We prove that polynomial size discrete Hoppeld networks with hidden units compute exactly the class of Boolean functions PSPACE/poly, i.e., the same functions as are computed by polynomial space-bounded nonuniform Turing machines. As a corollary to the construction, we observe also that networks with polynomially bounded interconnection weights compute exactly the class of functions P/poly, i.e...

We consider a non-uniform affine lambda-calculus, called parsimonious, and endow its terms with two type disciplines: simply-typed and with linear polymorphism. We show that the terms of string type into Boolean type characterize the class L/poly in the first case, and P/poly in the second. Moreover, we relate this characterization to that given by the second author in terms of Boolean proof ne...

The dechlorination of chlorinated hydrocarbons has been examined in detail. The reaction is catalyzed by cytochrome P-450 and occurs optimally in the presence of oxygen although some dechlorination may occur under anaerobic conditions. Halothane has been shown to undergo an oxidative dechlorination and a reductive defluorination. Enzymatic attack of chlorinated olefins and hydrocarbons is not o...

ACC is the class of all problems computable by constant depth, unbounded fan-in circuits with ∧,∨,¬ and MODm gates for any constant m. A related class to ACC is P/poly, which contains all problems computable by polynomial-size circuits with ∧,∨, and ¬ gates. IfC is a circuit with n inputs, then we use tt(C) to denote the string of length 2 obtained by evaluating C on all 2 possible inputs in le...

Relations between exposure to chlorinated compounds and biological markers of response to oxidative stimuli were investigated in swimmers, taking into account the effect of training. Twenty-two male swimmers aged 15-25 years were surveyed twice. Prevalence of irritant symptoms and asthma and number of hours of training were reported. Exposure to nitrogen trichloride (NCl3) and blood response to...

سرطان سینه نوعی از سرطان است که از سلول های بافت پستان به وجود می آید و همچنان بعنوان یک بیماری پیچیده که میلیون ها نفر را در سراسر جهان تحت تاثیر قرار می دهد، مطرح می باشد. جمع آوری آسیب های dna بعنوان یک عامل مهم در بروز سرطان سینه در زنان در نظر گرفته می شود. یکی از مهم ترین مکانیسم های دفاعی برعلیه آسیب های dna، مسیر ترمیم برداشت نوکلئوتیدی (ner) است. xerodermapigmentosum group c (xpc) یک ژ...
