Many garbage collectors on parallel computers are written in sequential languages, therefore thay are not portable across machines with different communication primitives. Moreover, the description of garbage collectors on distributed memory machines, which use asynchronous messages, is complex. We implemented a garbage collector for parallel object-oriented language Schematic by using Schemati...

An anionic trypsinogen has been identified and isolated in a state of high purity from porcine pancreatic tissue and juice extracts. The anionic trypsinogen is present in large amounts and accounts for about half of the total potential tryptic activity. The kinetics of the conversion of the anionic trypsinogen to active enzyme is autocatalytic, yielding an anionic trypsin which is less anionic ...

Our research is concerned with compiler-independent, tag-free garbage collection for the C ++ programming language. This paper presents a mark-and-sweep collector , and explains how it ameliorates shortcomings of a previous copy collector. The new collector, like the old, uses C ++ 's facilities for creating abstract data types to deene a tracked reference type, called roots, at the level of th...

Along with the prevalence of email, a number of free email managers have been developed to assist people to deal with personal and interpersonal affairs. Beside sending and receiving email, they provide a diversity of function such as memorandum and calendar. Many researchers are interested in how people communicate via email. They may have questions such as " how long does it take them to repl...

Motivated by applications in bioinformatics, we consider the word collector problem, i.e. the expected number of calls to a random weighted generator of words of length n before the full collection is obtained. The originality of this instance of the non-uniform coupon collector lies in the, potentially large, multiplicity of the words/coupons of a given probability/composition. We obtain a gen...

Solar-heated air can be used in a wide variety of applications, but it is a limited resource. Only so much sunshine strikes each square foot of the earth, and a well-built collector system will typically deliver about half of this energy to a house in the form of heat. The way this heat is used often means the difference between a useful, cost-effective system and one that never seems to perfor...

The novel characteristics of a new lateral PNM Schottky collector bipolar transistor (SCBT) on silicon-on-insulator (SOI) are explored using two-dimensional (2-D) simulation. The collector-base junction of the proposed lateral PNM transistor consists of a Schottky junction between n-base (N) and metal (M). The characteristics of this structure are compared with that of lateral PNP transistors o...

This paper describes the design and the evaluation of Complementary Garbage Collector that is a fundamental algorithm for the parallel and incremental garbage collector. Our algorithm is a combination of two types of fundamental algorithms, incremental update and snapshot-at-beginning, which are complementary to each other. The algorithm has the advantages of both types: great e ciency of the g...

Due to their availability, low cost, nontoxicity, and tunability, polymeric carbon nitrides (CNx) represent one of the most attractive materials classes for development fully sustainable photo(electro)catalytic systems solar-driven water splitting. However, CNx-based photoanodes visible light-driven oxidation dioxygen is rather challenging, particularly due issues related photoelectrode stabili...

Garbage collectors are an important part of many modern language runtimes. Essentially all tools for developing and debugging programs using garbage collection assume the correctness of the collector, and therefore provide no means for detecting garbage collector errors. As a result it is especially important that garbage collector implementations be free of errors. This goal is even more chall...
