Comparison of the Expressiveness of Timed Automata and Time Petri Nets [PDF]

, 2005
In this paper we consider the model of Time Petri Nets (TPN) where time is associated with transitions. We also consider Timed Automata (TA) as defined by Alur & Dill, and compare the expressiveness of the two models w.r.t. timed language acceptance and (weak) timed bisimilarity. We first prove that there exists a TA $\mathcal{A}$s.t.

Sex Differences in Countermovement Jump Phase Characteristics

Sports, 2017
The countermovement jump (CMJ) is commonly used to explore sex differences in neuromuscular function, but previous studies have only reported gross CMJ measures or have partly examined CMJ phase characteristics.

Comparison of bleeding time and clotting time between males and females

National Journal of Physiology, Pharmacy and Pharmacology, 2018
Background: Bleeding time (BT) depends on various factors such as functions of platelets and endothelial cells of arteries and pathways of coagulation. Clotting time (CT) is increased due to the absence or abnormality of clotting factors. BT is increased

Comparison of Five Thrombin Time Reagents [PDF]

Clinical Chemistry, 2003
The thrombin time (TT) assay is a core test in clinical laboratories that perform coagulation testing. This assay screens for abnormalities in the conversion of fibrinogen to fibrin. The time necessary for fibrinogen to clot is affected by hypofibrinogenemia, dysfibrinogenemia, and the presence of inhibitors of the fibrinogen-to-fibrin reaction ...

Early Body Mass Index z‐Score Change and Resolution of Severe Malnutrition in Children With Sickle Cell Anemia in a Low‐Income Setting: A Prospective Single‐Arm Extension Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Children with sickle cell anemia (SCA) in low‐income settings are at risk of severe malnutrition, but optimal nutritional management has not been established. We evaluated an intensified ready‐to‐use therapeutic food (RUTF) regimen in children with persistent severe malnutrition after initial treatment and assessed whether early ...

The Comparison of Correlations in Time-Series

Journal of the Royal Statistical Society Series B: Statistical Methodology, 1958
SUMMARY The problem considered is that of comparing two lengths of time-series to test whether their correlation structures are similar. It is pointed out that this may be usefully done only if assumptions are made concerning the type of correlation structure of each series.
