Connecting Threads: Epigenetics and Metabolism
Chromatin-modifying enzymes have long been proposed to be the authors of an epigenetic language, but the origin and meaning of the messages they write in chromatin are still mysterious. Recent studies suggesting that the effects of diet can be passed on epigenetically to offspring add weight to the idea that histones act as metabolic sensors, converting changes in metabolism into stable pattern...
متن کاملDistributed Shared-Memory Threads: DSM-Threads
This paper is, to our knowledge, the rst description of a system to support distributed threads on top of POSIX Threads (Pthreads) via distributed virtual shared memory (DSM). The aim of DSMThreads is to provide an easy way for a programmer to migrate from a concurrent programming model with shared memory (Pthreads) to a distributed model with minimal changes of the application code. Thus, a pr...
متن کاملVirtual Threads
Multithreaded servers, while relatively simple to design and to implement, tend not to scale well for large numbers of concurrent users. Event-driven servers, which do scale well, are generally more difficult to design, write, and debug than multithreaded servers. Virtual Threads is a new server programming model in which the programmer writes a multithreaded server and a preprocessor automatic...
متن کاملMissed threads
Over the past two decades, molecular genetic research has helped to elucidate the genetic component of many diseases and conditions. Patients can now be tested for a wide variety of disease-causing genes to improve dia gnoses and risk predictions for patients and their families (www.eddnal.com). This, in turn, has allowed physicians to provide advice on lifestyle or other preventative measures ...
متن کاملPersistent Threads
Persistent threads are a database programming concept particularly well-suited for a.pplications that manage long-term, distributed or cooperative activities. We introduce persistent threads as a novel form of bindings from data in persistent object stores to activated code and relate them to existing binding concepts found in database programming. We also describe the integration of persistent...
