A direct approach to exact solutions of nonlinear partial differential equations is proposed, by using rational function transformations. The new method provides a more systematical and convenient handling of the solution process of nonlinear equations, unifying the tanhfunction type methods, the homogeneous balance method, the exp-function method, the mapping method, and the F-expansion type m...

In real-world classification problems, the class balance in the training dataset does not necessarily reflect that of the test dataset, which can cause significant estimation bias. If the class ratio of the test dataset is known, instance re-weighting or resampling allows systematical bias correction. However, learning the class ratio of the test dataset is challenging when no labeled data is a...

We study the discovery reach for Non-Standard Interactions (NSIs) in a neutrino factory experiment. After giving a theoretical, but model-independent, overview of the most relevant classes of NSIs, we present detailed numerical results for some of them. Our simulations take into account matter effects, uncertainties in the neutrino oscillation parameters, systematical errors, parameter correlat...

We present the first attempt of the systematical investigation about the effects of shell correction energy for dynamical processes, which include fusion, fusion-fission and quasi-fission processes. In the superheavy mass region, for the fusion process, the shell correction energy plays a very important role and enhances the fusion probability, when the colliding partner has strong shell struct...

We report a systematical study of the temperature-dependence of negative deferential resistance (NDR) from double-barrier Al0.35Ga0.65N/GaN resonant tunneling diodes grown by plasma-assisted molecular-beam epitaxy on free-standing GaN substrates. The current–voltage (I–V) characterization was done in the 6–300 K temperature range. A clear NDR signature was observed for mesa sizes of 4 × 4 μm2 a...

Many businesses strive to align their business goals, strategies, and systems before during system development as the studies of GORE alignment business/IT show. However, level success derived from interrelationships may be ambiguous because relationships between are often vague. As agile becomes more prevalent, it is becoming difficult adjust a accommodate changing goals strategies. By linking...

This survey is accomplished by the purpose of effective social and cultural factors on educational progress of high-school students in Shoush city.Out of 3200 persons about 280 persons were selected as sample volume according to Cochran formula. Sampling method was simple random.The most appropriate theory for this research is Parsons systematical theory .In this survey ,the relation of 8 varia...
