Dietary supplementation of stearidonic acid (SDA; 18:4n-3) has been considered a possible strategy to increase n-3 unsaturated fatty acid content in ruminant products; however, little is known about its metabolism in the rumen. In vitro batch incubations were carried out with bovine ruminal digesta to investigate the metabolism of SDA and its biohydrogenation products. Incubation mixtures (4.5 ...

The following is a introduction to a method, called signed difference analysis (or SDA), that I have been developing, off and on, over the last seven years. SDA is a general technique for evaluating psychological models using only the “non-metric” or ordinal properties of dependent variables. Although still a work in progress, the following is an outline of its main elements which, hopefully, w...

INTRODUCTION The evidence for adrenaline in out-of-hospital cardiac arrest (OHCA) resuscitation is inconclusive. We systematically reviewed the efficacy of adrenaline for adult OHCA. METHODS We searched in MEDLINE, EMBASE, and Cochrane Library from inception to July 2013 for randomized controlled trials (RCTs) evaluating standard dose adrenaline (SDA) to placebo, high dose adrenaline (HDA), o...

This paper presents an exponential-based spiral dynamic algorithm (SDA) as an improved version of the original SDA. A simple structure with a unique feature of a spiral model in SDA leads the algorithm achieving fast convergence speed and short computation time. However, adopting a constant radius and a constant angle into the spiral model of SDA causes the algorithm to trap into local optima s...

Clinical specimens cultured on two selective fungal media, inhibitory mold agar (IMA) and Sabouraud dextrose agar (SDA), were compared with respect to recovery of fungi. Of the 840 fungal isolates recovered, 69.3% grew on both IMA and SDA; 24.9% grew only on IMA; and 5.8% grew only on SDA, showing that IMA is superior (P=0.003).

Macromolecular interactions play a crucial role in biological systems. Simulation of diffusional association (SDA) is a software for carrying out Brownian dynamics simulations that can be used to study the interactions between two or more biological macromolecules. webSDA allows users to run Brownian dynamics simulations with SDA to study bimolecular association and encounter complex formation,...

We introduce a new security notion for public-key encryption (PKE) that we dub non-malleability under (chosen-ciphertext) self-destruct attacks (NM-SDA), which appears to be the strongest natural PKE security notion below full-blown chosen-ciphertext (IND-CCA) security. In this notion, the adversary is allowed to ask many adaptive “parallel” decryption queries (i.e., a query consists of many ci...

This study evaluated a variation of functional assessment methodology, the structured descriptive assessment (SDA). The SDA is conducted in an individual's natural environment and involves systematically manipulating antecedent variables while leaving consequences free to vary. Results were evaluated by comparing the results of an SDA with results obtained from an analogue functional analysis w...

Deer antler preparations have been used to strengthen bones for centuries. It is particularly rich in collagen type I. This study aimed to unravel part of the purported bioremedial effect of Sika deer antler collagen type I (SDA-Col I) on bone marrow mesenchymal stem cells. The results suggest that SDA-Col I might be used to promote and regulate osteoblast proliferation and differentiation. SDA...

Traditional speech enhancement algorithms consider speech detection and estimation process independently. The simultaneous detection and estimation approach (SDA) combines both detection and estimation processes to reduce the effects due to missed detection. SDA is based on an estimator which minimizes bayesian risk with the aid of minimum mean square error (MMSE) estimator. The MMSE estimator ...
