Deterministic replay of parallel execution and communication operations is required both by HPC debuggers and resilience mechanisms. Despite its potential performance advantages, the inherent nondeterminism present in one-sided communication makes replaying difficult. The essential problem is that the readers of updated shared data do not have any information on which remote threads produced th...

The biogenesis and activity of chloroplasts in both vascular plants and algae depends on an intracellular network of nucleus-encoded, trans-acting factors that control almost all aspects of organellar gene expression. Most of these regulatory factors belong to the helical repeat protein superfamily, which includes tetratricopeptide repeat, pentatricopeptide repeat, and the recently identified o...

BACKGROUND In the past 20 years, various recommendations have been made about the maximum number of intrauterine insemination (IUI) cycles that should be performed, because evidence underpinning a possible limit is lacking. METHODS We performed a multicentre, retrospective cohort analysis among couples treated with IUI up to nine cycles. Primary outcome measure was ongoing pregnancy rate (OPR...

A new approach is described to analyse the barrier properties of the outer part of rice (Oryza sativa L.) roots towards oxygen. By using a root-sleeving O(2) electrode, radial oxygen loss at different distances from the root apex was measured and related to the corresponding root structure. In addition, internal oxygen concentrations were precisely adjusted using a newly developed perfusion tec...

Interstellar dark clouds are the sites of star formation. Their main component, dihydrogen exists under two states, ortho and para. H2 is supposed to form in the ortho:para ratio (OPR) of 3:1 and to subsequently decay to almost pure para–H2 (OPR ≤ 0.001). Only if the H2 OPR is low enough, will deuteration enrichment, as observed in the cores of these clouds, be efficient. The second condition f...

Purpose This study examines how congruent moral conviction between an individual and a company impacts organization-public relationships (OPR). Using arguments from the Attribution Theory, this also individuals' perceptions of motives impact quality OPR. offers new understanding what drives supporting behaviors regarding company's advocacy efforts ethics contribute to Design/methodology/approac...

In this paper, we first introduce two one-parameter relaxation (OPR) iterative methods for solving singular saddle point problems whose semi-convergence rate can be accelerated by using scaled preconditioners. Next we present formulas for finding their optimal parameters which yield the best semi-convergence rate. Lastly, numerical experiments are provided to examine the efficiency of the OPR m...

The abuse of prescription drugs has led to a significant increase in emergency department (ED) visits and drug-related deaths over the past decade. Opioid pain relievers (OPRs) and benzodiazepines are the prescription drugs most commonly involved in these events. Excessive alcohol consumption also accounts for a significant health burden and is common among groups that report high rates of pres...

BACKGROUND/AIMS Newer P2Y12 inhibitors, such as prasugrel and ticagrelor, have greater antiplatelet efficacy but may increase the risk of bleeding. In this study, we compared the pharmacodynamic efficacy of prasugrel and ticagrelor in East Asian patients with acute coronary syndrome (ACS). METHODS We selected 83 ACS patients undergoing percutaneous coronary intervention who were discharged wi...

Great interest in natural furanoside-containing compounds has challenged the development of preparative methods for their synthesis. Herein a novel reaction in carbohydrate chemistry, namely a pyranoside-into-furanoside (PIF) rearrangement permitting the transformation of selectively O-substituted pyranosides into the corresponding furanosides is reported. The discovered process includes acid-p...
