Experimenters and teachers use discrimination learning procedures to encourage reliable attending to stimulus differences defined as relevant for their purposes. Put another way, the goal of discrimination training is to establish high-probability stimulus control topographies that are coherent with experimenter or teacher specifications. The present research was conducted to investigate a nove...

Two sub-systems characterize the early stages of human colour vision, the 'L-M' system that differences L and M cone signals and the 'S' system that differences S cone signals from the sum of L and M cone signals. How do they interact at suprathreshold contrast levels? To address this question we employed the method used by Kingdom et al. (2010) to study suprathreshold interactions between lumi...

People can accurately assess various personality traits of others based on body odor (BO) alone. Previous studies have shown that correlations between odor ratings and self-assessed personality dimensions are evident for assessments of neuroticism and dominance. Here, we tested differences between assessments based on natural body odor alone, without the use of cosmetics and assessments based o...

background: bread is the major food in middle east and iran. recent studies in iran have shown that daily bread consumption was 300gr. also, 40.2% of the total energy per person was obtained from bread. methods: this cross-sectional study was done in 81 bakeries in rafsanjan, iran in 2004. the main objective of this study was to determine some parameters of the bread, such as ph, nacl, dough an...

This paper discusses new bounds for restricted isometry property in compressed sensing. In the literature, E.J. Candès has proved that δ2s < √ 2 − 1 is a sufficient condition via l1 optimization having s-sparse vector solution. Later, many researchers have improved the sufficient conditions on δ2s or δs. In this paper, we have improved the sufficient condition to δs < 0.309 and have given the s...

Abstract. A set S ⊆ R is called to be Semidefinite (SDP) representable if S equals the projection of a set in higher dimensional space which is describable by some Linear Matrix Inequality (LMI). Clearly, if S is SDP representable, then S must be convex and semialgebraic (it is describable by conjunctions and disjunctions of polynomial equalities or inequalities). This paper proves sufficient c...

the concept of redevelopment is accompanied by actions and forecasts to improve the quality of the physical-spatial environment inthe cities, that is by the emergence of new facilities and conditions, improving the spatial environment is achieved. this requirement occurs when the coherence, coordination and the performance of the urban area is diminishing and is not responsive to the requiremen...

In this paper the notion of s-irrelevance with respect to upper and lower conditional probabilities assigned by Hausdorff outer and inner measures is proved to be a sufficient condition for strong independence introduced for credal sets. An example is given to show that the converse is not true. Moreover the definition of sconditional irrelevance is given and a generalized factorization propert...

We study a stationary, single-stage inventory system, under periodic review, with fixed ordering costs and multiple sales levers (such as pricing, advertising, etc.). We show the optimality of (s, S)-type policies in these settings under both the backordering and lost-sales assumptions. Our analysis is constructive, and is based on a condition which we identify as being key to proving the (s, S...

For a closed target set S ⊂ R and a control system (formulated as a differential inclusion and defined near S), the present paper considers a sufficient condition for the property that every point near S can be steered to S in finite time by some trajectory of the system. Estimates are obtained revealing how fast some such trajectory is nearing the target. A strong form of this condition is sho...
