BACKGROUND Current therapies for pulmonary arterial hypertension have been adopted on the basis of short-term trials with exercise capacity as the primary end point. We assessed the efficacy of macitentan, a new dual endothelin-receptor antagonist, using a primary end point of morbidity and mortality in a long-term trial. METHODS We randomly assigned patients with symptomatic pulmonary arteri...
Clostridium thermocellum is a thermophilic, anaerobic, cellulolytic bacterium that produces ethanol and acetic acid as major fermentation end products. The effect of growth conditions on gene expression in C. thermocellum ATCC 27405 was studied using cells grown in continuous culture under cellobiose or cellulose limitation over a approximately 10-fold range of dilution rates (0.013 to 0.16 h(-...
The relations between lysin concentration, percentage hemolysis at the moment at which the lysin concentration is reduced by dilution, and the amount of hemolysis which follows the dilution as a result of the reaction being "progressive" point to there being an "internal" phase at the red cell surfaces, in which the lysin is less affected by the dilution than in the system as a whole. A second ...
BACKGROUND The analysis of red cell folate (RCF) depends on complete hemolysis of erythrocytes, and it is assumed that complete hemolysis is achieved by 10-fold dilution of whole blood with hypotonic solutions of 10 g/L ascorbic acid/ascorbate. This report challenges this assumption. METHODS The conventional method of erythrocyte lysis was modified to include saponin, a known effective hemoly...
A new continuous speech recognition method that does not need the explicit speech end-point detection is proposed. A one-pass decoding algorithm is modified to decode the input speech of infinite length so that, with appropriate nonspeech models for silence and ambient noises, continuous speech recognition can be executed without the explicit endpoint detection. The basic algorithm is 1) decode...
Cryptographic protocols are useful for engineering trust in transactions. There are several languages for describing these protocols, but these tend to capture the communications from the perspective of an individual role. In contrast, traditional protocol descriptions as found in a state of nature tend to employ a whole-protocol description, resulting in an impedance mismatch. In this paper we...
A video interface with end-point security is able to protect the confidentiality of electronic information up until the scan-line conversion process. Data stored in the video RAM remains encrypted, and this feature can be used to support design rights management. We describe the implementation of an end-pointsecure character-based VGA video interface. Video data confidentiality is maintained by...
We investigate the critical end point (CEP) of QCD with two flavours of light dynamical quarks at finite lattice cutoff a = 1/4T using a Taylor expansion of the baryon number susceptibility. We find a strong volume dependence of the position of the critical end point. In the large volume limit we obtain T /Tc ≈ 0.95 and μE B /T E ≈ 1.1, where Tc is the cross over temperature at zero chemical po...
BACKGROUND Pyrimidine is an aromatic heterocyclic moiety containing nitrogen atom at 1st and 3rd positions and play an important role to forms the central core for different necessity of biological active compounds, from this facts, we have designed and synthesized a new class of pyrimidin-2-ol/thiol/amine derivatives and screened for its in vitro antimicrobial activity. RESULTS AND DISCUSSIO...
Using general arguments we determine the allowed region for the end point frequency and the peak energy density of the stochastic background of gravity waves expected in string cosmology. We provide an accurate estimate of the minimal experimental sensitivity required to detect a signal in the Hz to GHz range.
