New criteria of Lp − Lq boundedness of Hardy-Steklov type operator (1.1) with both increasing on (0, ∞) boundary functions a(x) and b(x) are obtained for 1 < p ≤ q < ∞ and 0 < q < p < ∞, p > 1. This result is applied for two-weighted Lp − Lq characterization of the corresponding geometric Steklov operator (1.3) and other related problems.

We study the lattice finite representability of the Bochner space Lp(μ1, Lq(μ2)) in `p{`q}, 1 ≤ p, q < ∞, and then we characterize the ideal of the operators which factor through a lattice homomorphism between L∞(μ) and Lp(μ1, Lq(μ2)).

Strategies for preventing undernutrition comprise a range of interventions, including education, provision of complementary food and cash transfer. Here, we compared monthly distributions of two different lipid-based nutrient supplements (LNS), large-quantity LNS (LNS-LQ) and medium-quantity LNS (LNS-MQ) for 15 months on prevention of undernutrition among children 6 to 23 months. Both groups al...

Rank minimization problems, which consist of finding a matrix of minimum rank subject to linear constraints, have been proposed in many areas of engineering and science. A specific problem is the matrix completion problem in which a low rank data matrix is recovered from incomplete samples of its entries by solving a rank penalized least squares problem. The rank penalty is in fact the l0 norm ...

We reconsider the optimal taxation of income from labor and capital in the stochastic growth model analyzed by Chari et al. (1994, 1995), but using a linear-quadratic (LQ) approximation to derive a log-linear approximation to the optimal policy rules. The example illustrates how inaccurate “naive” LQ approximation — in which the quadratic objective is obtained from a simple Taylor expansion of ...

We present a linguistically-motivated technique for the recognition and grouping of simplex noun phrases (SNPs) called LinkIT. Our system has two key features: (1) we efficiently gather minimal NPs, i.e. SNPs, as precisely and linguistically defined and motivated in our paper ; (2) we apply a refined set of postprocessing rules to these SNPs to link them within a document. The identification of...

Abstract With the development of social and economic research, judgements that people deal with are full fuzziness vagueness. It is convenient to use linguistic q-rung orthopair fuzzy numbers offer qualitative uncertain information. Consequently, in this paper, we mainly study preference relations (Lq-ROFPRs) apply them a multi-criteria decision-making (MCDM) problem. The multiplicative consist...

Integration of semistructured information is a new research topic in database area. Different approaches has been proposed in the past years, however no satisfactory solution has been found. In this paper, we present our approach of using conceptual modeling and intelligent agents to integrate semistructured data. We use a database coupled with intelligent agents to warehouse semistructured dat...
