The incidence and severity of coronary arteriosclerosis were studied in 209 wild and cultured Atlantic salmon (Salmo salar L.) during various stages of recovery of bodily condition after spawning. All recently spawned fish had lesions of moderate to extreme severity. The incidence of lesions for each fish was high (73% to 94% of all arterial cross-sections examined). The incidence and severity ...

Parameterized quadratic programming (Lasso) is a powerful tool for the recovery of sparse signals based on underdetermined observations contaminated by noise. In this paper, we study the problem of simultaneous sparsity pattern recovery and approximation recovery based on the Lasso. An extended Lasso method is proposed with the following main contributions: (1) we analyze the recovery accuracy ...

We investigate the sparse recovery problem of reconstructing a high-dimensional non-negative sparse vector from lower dimensional linear measurements. While much work has focused on dense measurement matrices, sparse measurement schemes are crucial in applications, such as DNA microarrays and sensor networks, where dense measurements are not practically feasible. One possible construction uses ...

Due to its wide range of hazardous hydrocarbons and even heavy metal ions, oily sludge has become a great environmental challenge which must be dealt with quite quickly. As a result, ther have been numerous efforts during recent years to develop an efficient method for sludge recovery. The current research studies the effectiveness of solvent extraction with toluene and Fe2O3 nanoparticles for ...

Conventional heat resistance data, D values, were previously established by other workers at optimal condition for spores outgrowth. However, in canned food conditions of outgrowth are generally suboptimal in term of pH, salt concentration, water activity. The combined effects of pH and NaCl level of the recovery medium for the D value and z(pH) value were studied. Spores of Bacillus cereus wer...

Deposits can affect the in-furnace wall surface temperature in a Kraft recovery furnace. In CFD (Computational Fluid Dynamics) models of the Kraft recovery furnace, the wall surface temperature is frequently used as the heat-transfer boundary condition. Therefore, the effect of deposits must be taken into account in CFD models. In this work, CFD simulations of a Kraft recovery furnace were perf...

Conceptualizing aetiology underpinning an individual's substance use disorder (SUD) not only facilitates insight and understanding, but also serves to identify targets for treatment and aid practitioners in selecting the most appropriate interventions. There is now a wealth of literature on aetiology and treatment approaches, and in more recent years, also literature to support the concept of '...

We consider the recovery of jointly sparse multichannel signals from incomplete measurements using convex relaxation methods. Worst case analysis is not able to provide insights into why joint sparse recovery is superior to applying standard sparse reconstruction methods to each channel individually. Therefore, we analyze an average case by imposing a probability model on the measured signals. ...

Tracheostomy refers to a surgical incision created in the neck allow direct air entry into trachea bypassing upper respiratory tract including oral and nasal cavities. Normal vocalization swallowing are limited immediately postoperatively; however, gradual recovery of function can be initiated, following improvement causative condition that necessitated tracheostomy. Duration tracheostomy depen...

the purpose of this study was to examine the effectiveness of nanosilver colloid as a new antimicrobial agent against erwinia in tissue culture of sugar beet for the recovery of the contaminated doubled haploid plantlets. the nanosilver colloidal solution of 4000 ppm was diluted in different concentrations (0, 50, 75, 100 and 125 ppm) and was added to the solid ms medium. in a factorial experim...
