Simultaneous Bayesian Sparse Approximation with Structured Sparse Models [PDF]

, 2016
Sparse approximation is key to many signal processing, image processing and machine learning applications. If multiple signals maintain some degree of dependency, for example the support sets are statistically related, then it will generally be ...

Proposals for improving the efficiency and service life of the turbines of turbo-pump assemblies in liquid-propellant rocket engines by using double-sided crest-type radial labyrinth seals

Вестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2018
Nowadays the improvement of the design of liquid-propellant rocket engines (LPREs) depends on a variety of factors and activities, among which we can distinguish, for example, the improvement of energy characteristics of units and assemblies forming part

Mycobacterium tuberculosis LprE enhances bacterial persistence by inhibiting cathelicidin and autophagy in macrophages [PDF]

, 2017
ABSTRACT Mycobacterium tuberculosis(Mtb) lipoproteins are known to facilitate bacterial survival by manipulating the host immune responses. Here, we have characterized a novel Mtb lipoprotein LprE(LprE Mtb ), and demonstrated its

ANALYSIS OF THE INFLUENCE OF CONSTRUCTIVE FLOWING PART OF A INDUCER-CENTRIFUGAL PUMP FOR ITS CAVITATIONAL CHARACTERISTICS

Авіаційно-космічна техніка та технологія, 2018
The phenomenon of cavitation is inherent in all vane machines, the working medium of which is liquid. With a certain combination of input pressure, flow rate, rotor speed, and the gas saturation of the working fluid in the vane machine, cavitation may ...

Effects of Leakage Neutral Particles on Shocks

, 2012
In this paper we investigate effects of neutral particles on shocks propagating into the partially ionized medium. We find that for 120 km/s < u_{sh} < 3000 km/s (u_{sh} is the shock velocity), about ten percent of upstream neutral particles leak into ...

L0-regularized high-dimensional sparse multiplicative models

Statistical Theory and Related Fields
In this paper, we study high-dimensional sparse multiplicative models for positive response data and propose a variable sorted active set (VSAS) algorithm for finding the [Formula: see text] regularized least product relative error (LPRE) estimator.

Terahertz master-oscillator power-amplifier quantum cascade laser with a grating coupler of extremely low reflectivity [PDF]

, 2018
A terahertz master-oscillation power-amplifier quantum cascade laser (THz-MOPA-QCL) is demonstrated where a grating coupler is employed to efficiently extract the THz radiation.
