A novel coded excitation method, resolution enhancement compression (REC), increases the axial resolution and the echo signal-to-noise ratio (eSNR) for an ultrasonic imaging system. The REC technique was examined for its ability to improve lesion detectability. In addition to lesion detectability, the REC technique was examined in the context of being peak voltage limited or peak pressure limit...

BACKGROUND Widely used restriction-dependent cloning methods are labour-intensive and time-consuming, while several types of ligase-independent cloning approaches have inherent limitations. A rapid and reliable method of cloning native DNA sequences into desired plasmids are highly desired. RESULTS This paper introduces ABI-REC, a novel strategy combining asymmetric bridge PCR with intramolec...

Thrombomodulin (TM), a membrane proteoglycan on endothelial cells, binds thrombin in a 1:1 complex, accelerates the protein C activation by thrombin, promotes the thrombin inactivation by antithrombin III and inhibits the procoagulant properties of thrombin. The inactivation of single-chain urokinase-type plasminogen activator (scu-PA) by thrombin is accelerated about 70-fold by TM [De Munk, Gr...

Protecting children from injuries caused by fall accidents from playground equipment is important. Therefore, measures toward minimizing the risk of fall accident injuries are required. The risk of injury can be evaluated using ASTM F1292. In this test, G-max and the HIC are used to estimate the risk of injury. However, the measurement procedure is too complicated for application to a large num...

A linear stability analysis is applied to determine the onset of oscillatory thermocapillary convection in cylindrical liquid bridges of large Prandtl numbers (4 6 Pr 6 50). We focus on the relationships between the critical Reynolds number Rec, the azimuthal wave number m, the aspect ratio Γ and the Prandtl number Pr. A detailed Rec-Pr stability diagram is given for liquid bridges with various...

The central nervous system depressant activity of the crude methanol extract (REC) and fractions (RE1, RE2, and RE3) of Russelia equisetiformis were evaluated in mice using the following models: amphetamine-induced stereotypy, picrotoxin-induced convulsion and phenobarbitone sleeping time. At 200-400 mg/kg, REC significantly increased phenobarbitone-sleeping time [P < 0.05] in a dose- dependent...

We present a disjoint reachability analysis for Java. Our analysis computes extended points-to graphs annotated with reachability states. Each heap node is annotated with a set of reachability states that abstract the reachability of objects represented by the node. The analysis also includes a global pruning step which analyzes a reachability graph to prune imprecise reachability states that c...

This paper presents the results of an exploratory experiment investigating the use of program metrics to predict reachability graph size, reachability graph generation time, and deadlock check times for concurrent Ada programs. In general, reachability analysis is intractable, so it is important to be able to predict whether or not this analysis technique is feasible given a specific program to...

Health research that seeks the participation of patients requires ethical and administrative clearances through the NHS research governance process. This is a two-stage process which involves a central Research Ethics Committee (REC), and Research and Development (R&D) at specific Trusts. Reflection is undertaken from a researcher’s perspective on their experience of negotiating NHS research go...

Twenty healthy subjects with at least two Miller Class I gingival recessions (RECs) crossing the midline in the maxilla were enrolled for the study. Fifty-six (mean initial REC = 2.3 ± 0.9 mm) and 75 (mean initial REC = 2.3 ± 1.1 mm) RECs were treated in the test and control groups, respectively. All of the cases were treated by means of CAF without vertical releasing incisions: ten were random...
