Parallel job scheduling is an important problem whose solution may lead to better utilization of modern parallel computers. It is de ned as : Given the aggregate of all tasks of multiple jobs in a parallel system, nd a spatial and temporal allocation to execute all tasks e ciently . For the purposes of scheduling, we view a computer as a queueing system. An arriving job may wait for some time, ...

1.1 Définitions élémentaires Définition 1. Soit P ∈ k[X ] et a ∈ k. On dit que a est une racine de P si P (a) = 0, ou de manière équivalente si X − a divise P . On appelle multiplicité de a le plus grand entier μ tel que (X − a) divise P . Proposition 1. Si P ∈ k[X ] admet a1, . . . , al pour racines, de multiplicités respectives μ1, . . . , μl, alors il existe Q ∈ k[X ] tel que P = Q∏(X − ai)i...

Finalement, je tiensà remercier ma famille et mes amis pour leur soutien et, tout simple-ment, pour leur présencè a mes côtés en toutes circonstances.

Effective chemotherapeutic strategies for uterine sarcoma are lacking; existing therapies achieve poor response rates. Previous studies have identified the prostaglandin 15-deoxy-Δ12,14-prostaglandin J2 (15d-PGJ2) as a potential anticancer treatment; however, its effectiveness in uterine sarcoma has not been examined. Furthermore, the molecular mechanisms underlying the cytotoxic mechanism of 1...

Embryonic stem (ES) cells provide a potentially useful in vitro model for the study of in vivo tissue differentiation. We used mouse and human ES cells to investigate whether the lens regulatory genes Pax6 and Six3 could induce lens cell fate in vitro. To help assess the onset of lens differentiation, we derived a new mES cell line (Pax6-GFP mES) that expresses a GFP reporter under the control ...

During animal development, gene transcription is tuned to tissue-appropriate levels. Here we uncover antagonistic regulation of transcript levels in the germline of Caenorhabditis elegans hermaphrodites. The histone methyltransferase MES-4 (Maternal Effect Sterile-4) marks genes expressed in the germline with methylated lysine on histone H3 (H3K36me) and promotes their transcription; MES-4 also...

BACKGROUND Cardiac resynchronization therapy is widely used for the treatment of heart failure. Recent data suggest that electric separation during left ventricular pacing varies within the right ventricle (RV). We hypothesized that placement of the RV lead guided by maximal electric separation (MES) would improve response to cardiac resynchronization therapy compared with standard apical place...

OBJECTIVE We had the objective to determine the impact of clinical parameters and anticoagulation status on cerebral microembolic signals (MES) during pulmonary vein isolation (PVI) for atrial fibrillation (AF). BACKGROUND Thromboembolism and stroke are the most feared complications of PVI. MES can help to evaluate embolic burden. It is unknown whether clinical parameters have an impact on em...

Today, most semiconductor manufacturing companies utilize Manufacturing Execution Systems (MES) (MacDonald, 1993; Samanish, 1993; Nguyen, 1996; Scatt, 1996; MESA, 1997) to deliver information to optimize production activities from order booking through design, production, and marketing to realize the agile manufacturing enterprise. The MES market is composed of several vendors providing an inte...
