We reproduce masses of the self-conjugate and non-self-conjugate mesons in the context of the spinless Salpeter equation taking into account the relativistic kinematics and the quark spins. The hyperfine splittings for the 2S charmonium and 1S bottomonium are also calculated. Further, the pseudoscalar and vector decay constants of the Bc meson and the unperturbed radial wave function at the ori...

This paper presents a new Kalman filter-based Recently, the parametric spectrum of pressure signals, power spectral density estimation (PSD) algorithm for including arterial, intracranial, cardiac pressure, etc. has nonstationary pressure signals. The pressure signal is assumed been studied by Aboy et al. [4, 5]. They constructed a novel to be an autoregressive (AR) process, and a stochasticall...

The term ”Homogeneous Least Squares (HLS)” refers to models of the form Y a ≈ 0, where Y is some data matrix, and a is an unknown parameter vector to be estimated. Such problems are encountered, e.g., when modeling Auto-Regressive (AR) processes. Naturally, in order to apply a Least-Squares solution to such models, the parameter vector a has to be somehow constrained in order to avoid the trivi...

Molecular dynamics simulations have been used extensively to model the folding and unfolding of proteins. The rates of folding and unfolding should follow the Arrhenius equation over a limited range of temperatures. This study shows that molecular dynamic simulations of the unfolding of crambin between 500K and 560K do follow the Arrhenius equation. They also show that while there is a large am...

The novel momentum analysis technique introduced by Danielewicz and Odyniec can be used to detect and exhibit collective flow in the light System Ar(1800 MeV/nucleon) + KC1 where the usual kinetic energy flow analysis fails. The microscopic Vlasov-Uehling-Uhlenbeck theory which includes the nuclear mean field, two-body collisions, and Pauli blocking is used to study this phenomenon. The resulti...

OBJECTIVES The aim of this prospective study of adult patients operated with a cryopreserved aortic homograft was to use serial echocardiographic data to evaluate the postoperative hemodynamic performance of these valves. BACKGROUND Only limited data on hemodynamic performance of aortic homografts at rest and during exercise are available. Controversy also exists regarding incidence and progr...

In an urban environment, a multipath propagation is one of the basic phenomena affecting a quality of received signals. This causes dispersions in time and angular domains. Basic parameters describing these dispersions are the rms delay spread and rms angle spread, respectively. The delay spread is related to a frequency of the transmitted signal and the nature of the propagation environment. I...

This paper shows results of narrowband path loss measurements in a typical urban and suburban mobile-tomobile radio environment at 900 MHz band. The measurements were made with two omni-directional antennas with a transmitter and a receiver antenna height of 1.5 meters. The results of measurements provide practical values for path loss exponent and standard deviation of shadowing in a nonline-o...

In a companion paper [4], space-time layered architectures (BLAST) and turbo coding/processing techniques, which are effective for single-link transmission, are combined with multiuser detection (MUD) methods for combating intercell interference. It is shown that, depending on the channel configuration, linear MMSE or successive interference cancellation (SIC) can be the preferable MUD method. ...
