Based on the observed strong-motion records of K-NET and KiK-net, we utilized 1,065 earthquake observation stations installed throughout Japan, gathering more than 140,000 recordings for weak motions with a peak ground acceleration (PGA) less 100 cm/s2 5,300 strong PGA cm/s2. These sites detected at least one recording value greater were used to quantify horizontal-to-vertical spectral ratio (H...
The number of incident cancers and long-term cancer survivors is expected to increase substantially for at least a decade. Advanced technology radiotherapies, e.g., using beams of protons and photons, offer dosimetric advantages that theoretically yield better outcomes. In general, evidence from controlled clinical trials and epidemiology studies are lacking. To conduct these studies, new resea...
We measured with unprecedented precision the induced polarization P(y) in (4)He(e,e'p)(3)H at Q(2)=0.8 and 1.3 (GeV/c)(2). The induced polarization is indicative of reaction-mechanism effects beyond the impulse approximation. Our results are in agreement with a relativistic distorted-wave impulse approximation calculation but are overestimated by a calculation with strong charge-exchange effec...
New estimates of freshwater discharge from continents were derived using stream-flow records from the world's largest 921 rivers, supplemented with estimates of discharge from unmonitored areas based on the ratios of runoff and drainage area between the unmonitored and monitored regions. The farthest downstream river-flow data were extrapolated to the river mouth using river transport model sim...
A net-like nanostructure of silicon named silicon nanonet was designed and oxygen atoms were used to passivate the dangling bonds. First-principles calculation based on density functional theory with the generalized gradient approximation (GGA) were carried out to investigate the energy band gap structure of this special structure. The calculation results show that the indirect-direct band gap ...
OBJECTIVE To test the hypothesis that including preoperative electrocardiogram (ECG) characteristics with clinical variables significantly improves the new-onset postoperative atrial fibrillation prediction model. DESIGN Retrospective analysis. SETTING Single-center university hospital. PARTICIPANTS Five hundred twenty-six patients, ≥ 18 years of age, who underwent coronary artery bypass ...
To avoid conflict and deadlock states in waterway with multiple locks and canals, a computer based traffic management system with proper control policy must be applied. The paper proposes a formal method for design of deadlock prevention supervisor by using discrete event theory, multiple reentrant flowlines class of Petri net and P-invariants control places calculation. By using and/or matrix ...
