Time-dependent unitary transformations are used to study the Schrödinger equation for explicitly timedependent Hamiltonians of the form H(t) = ~ R(t) · ~ J , where ~ R is an arbitrary real vector-valued function of time and ~ J is the angular momentum operator. The solution of the Schrödinger equation for the most general Hamiltonian of this form is shown to be equivalent to the special case ~ ...

in recent years, impinging streams have received increasing interest for their high efficiency in heat and mass transfer. this numerical study was conducted to investigate flow and heat transfer characteristics of one-way opposing jets of non-newtonian fluids. effects of reynolds number impinging angle, momentum ratio and flow behavior index on mixing index were evaluated. the results showed im...

The purpose of this study is to compare the impacts of momentum on stock returns of companies listed in Tehran Stock Exchange in different market conditions. For this purpose, the sample size is 120 months from 2008 to 2017. The research hypotheses are estimated using multivariate linear regression using time series method. Based on the results of the hypotheses test, the momentum in each of th...

Lattice QCD calculations locate the QCD critical point at energies accessible at the CERN Super Proton Synchrotron (SPS). We present average transverse momentum and multiplicity fluctuations , as well as baryon and anti-baryon transverse mass spectra which are expected to be sensitive to effects of the critical point. The future CP search strategy of the NA61/SHINE experiment at the SPS is also...

To study human lateral stabilization strategies, we developed a simple model using pendulums and a momentum wheel representing human appendages, and we recorded appendage data from 7 subjects during one-legged standing. We demonstrated that simple pendulum models can explain some of the strategies employed by humans to stabilize and that the basic strategy people employ to stabilize themselves ...

These proceedings describe Sleuth, a quasi-model-independent search strategy targeting new electroweak scale physics, and its application to 927 pb of CDF II data. Exclusive final states are analyzed for an excess of data beyond the Standard Model prediction at large summed scalar transverse momentum ( P pT ). This analysis of highP pT data represents one of the most encompassing searches so fa...

T he first child survival revolution led by UNICEF saw a fall in global under five child mortality (U5MR) from 121 in 1980 to 88 in 1986. It brought together the big players in international health and built momentum through a strategy of social mobilisation. This focused on four low cost primary care interventions (growth monitoring, oral rehydration, breast feeding, and immunisation). The sec...

In this paper, we consider the unilateral frictional contact problem of a hyperelastic body in the case of large displacements and small strains. In order to retain the linear elasticity framework, we decompose the deformation into a large global rotation and a small elastic displacement. This co-rotational approach is combined with a primal-dual active set strategy to tackle the contact proble...
