Paged Two-Level Memories: Approximate Models and Efficient Computations,IRM requirements in computer time and space exceed the available resources when formula (4.34) or its explicit variants, e.g. (4.35) or (4.36), are used. A similar shortcoming obtains in general in the Markov model of program behavior.大量杀死 发表于 2025-3-23 15:05:06
Secondary Storage,patterns normally influence system performance, and they are determined by the mechanism that allocates specific storage locations to records (units of information). Thus, in the calculation of conventional performance measures we refer to essentially combinatorial problems in which the effects of different record allocations are studied.血友病 发表于 2025-3-23 19:11:11
Buffer Storage,ign parameter is the buffer size, which must be sufficiently large to accommodate large backlogs of messages or data units that may occasionally develop because of large, transient demands of the input process. Accordingly, we shall discuss the problem of finding the steady state distribution of the amount of information stored in the buffer.容易生皱纹 发表于 2025-3-24 01:43:54
Primary Computer Storage,is, for in many Markov models it means that we have to carry along as part of the state variable an indication of the size of each item in memory. These have been termed models of “exact content” by Beneŝ .GRAVE 发表于 2025-3-24 05:20:34
tivity is also the presumed mechanism underlying several common and uncommon disorders such as migraine headaches, preeclampsia, and vasospastic angina. While epidemiologic studies (case reports, case series, and some controlled studies) have linked RP and these conditions, there is yet to be any clOASIS 发表于 2025-3-24 07:42:46

dexrazoxane are two novel drugs with some uniquely useful features. They block cell division at the G2/M border, but nowhere else, so that they have a low toxicity profile. They suppress tumor metastasis and haemorrhages through normalization of pathological blood vessels. Razoxane potentiates radi雄伟 发表于 2025-3-24 15:02:55
. Dexrazoxane has two potential pharmacological activities: it is a prodrug that is hydrolyzed to an iron chelating EDTA-type structure, and it is also a strong inhibitor of topoisomerase II. The anthracycline doxorubicin is able to be reductively activated to produce damaging reactive oxygen speciebrowbeat 发表于 2025-3-24 19:29:53
