Salvia officinalis, L. (Lamiaceae) is one of the most widespread herbal species used in the area of human health and in the food-processing industry. Salvia and its extracts are known to be a rich source of antioxidants. As shown previously, the crude ethanolic extract of salvia (SE) exerts lower anti-oxidative properties in lard compared to the new salvia food formulations No. 1 (SF1; 32% of S...

BACKGROUND Salvia divinorum, a hallucinogenic herb, has in recent years become popular among teenagers and young adults. Salvia is presently marketed as a "legal" alternative to other drugs of abuse, but little is known about the clinical toxicity of this substance. OBJECTIVES The purpose of this study is to describe the clinical and demographic features of this emerging substance of recreati...

In this paper we study the problem that when a Boolean function can be represented as the sum of two bent functions. This problem was recently presented by N. Tokareva in studying the number of bent functions [20]. Firstly, many functions, such as quadratic Boolean functions, MaioranaMacFarland bent functions, partial spread functions etc, are proved to be able to be represented as the sum of t...

This paper discusses homogeneous bent functions. The space of homogeneous functions of degree three in six boolean variables was exhaustively searched and thirty bent functions were found. These are found to occur in a single orbit under the action of relabeling of the variables. The homogeneous bent functions identiied exhibit interesting combinatorial structures and are, to the best of our kn...

In this paper, we show the rst method to construct vecto-rial bent functions which satisfy both the largest degree and the largest number of output bits simultaneously. We next apply this method to construct balanced vectorial Boolean functions which have larger non-linearities than previously known constructions.

In the literature, few constructions of n-variable rotation symmetric bent functions have been presented, which either have restriction on n or have algebraic degree no more than 4. In this paper, for any even integer n = 2m ≥ 2, a first systemic construction of n-variable rotation symmetric bent functions, with any possible algebraic degrees ranging from 2 to m, is proposed.

We show how to construct semi-bent Boolean functions from PSaplike bent functions. We derive infinite classes of semi-bent functions in even dimension having multiple trace terms.

BACKGROUND Salvia divinorum has known hallucinogenic effects and is legal in most parts of the United States. Given that this psychoactive substance has a potential of misuse and abuse, further data regarding the clinical and psychosocial factors associated with use are needed. OBJECTIVES To examine the clinical and psychosocial characteristics associated with use of salvia. METHODS The stu...
