Developers of multi-threaded servers face many challenges. One important challenge is selecting a suitable concurrency model. There are several concurrency models to choose from including thread-per-request, thread-pool, and threadper-session. Our last two columns discussed the thread-perrequest and thread-pool concurrency models, respectively. We showed how each could be used to develop multi-...

OBJECTIVE To evaluate the long-term success of the thread-lift procedure for facial rejuvenation. METHODS Thirty-three patients underwent a thread-lift procedure alone or in combination with other facial rejuvenation procedures to the brow, midface, jowl, and neck. Ten patients underwent thread-lifts only, and 23 had thread-lifts with other procedures. Ten additional patients having had non-t...

The stability of one liquid thread immersed in a fluid in a shear field is considered by linear stability analysis. A constant shear stress is imposed far away from the thread. The shear flow tends to deform and elongate the thread. The stability of the thread is characterized by the growth rate of a random perturbation. The equation for the growth rate leads to an eigenvalue problem with the w...

Dynamic thread duplication is a known redundancy technique for multi-cores. The approach duplicates a thread under observation for some time period and compares the signatures of the two threads to detect errors. Hybrid multi-cores, typically implemented on platform FPGAs, enable the unique option of running the thread under observation and its copy in different modalities, i.e., software and h...

BACKGROUND Thread lifting has become popular as a minimally-invasive suspension procedure, but there is little basic and clinical evidence in the literature on the long-term effects. OBJECTIVES The authors investigate the effects of two types of lifting threads in a rat model over the course of seven months. METHODS The dorsal skin of 18 Wistar rats was implanted with a 20-mm fragment of on...

N4016 makes a case for adding execution modes for threads of execution that are less capable than std::thread; doing so either allows for avoiding runtime overheads of std::thread or enables semantically different ways to execute such as SIMD loops. This paper defines the semantics of these lighter-weight modes of execution by defining certain kinds of execution agents (EAs). An EA is a mechani...

Threads as considered in thread algebra model behaviours to be controlled by some execution environment: upon each action performed by a thread, a reply from its execution environment – which takes the action as an instruction to be processed – determines how the thread proceeds. In this paper, we are concerned with the case where the execution environment is remote: we describe and analyse som...
