Although Particle Swarm Optimization (PSO) has demonstrated competitive performance in solving global optimization problems, it exhibits some limitations when dealing with optimization problems with high dimensionality and complex landscape. In this paper, we integrate some problem-oriented knowledge into the design of a certain PSO variant. The resulting novel PSO algorithm with an inner varia...

This study examined the order-to-delivery (OTD) process that employ real-time performance measurement based on digital visualization (DV). It was performed as a longitudinal case using design science approach. The company delivers customized technology solutions to its customers, with specific focus OTD of maintenance services. DV, it found, is powerful tool capable enhancing process. Determini...

Summary Objectives: The COVID-19 lockdown may lead to rising numbers of domestic violence (DV), especially among previously victimized individuals. aim this study was investigate the development and influential factors DV during early lockdown. Methods: In telephone-based study, previous participants with (n = 34) without 33) completed questionnaires on DV, attachment related stressors. Develop...

the first geometric-arithmetic index was introduced in the chemical theory as the summationof 2 du dv /(du  dv ) overall edges of the graph, where du stand for the degree of the vertexu. in this paper we give the expressions for computing the first geometric-arithmetic index ofhexagonal systems and phenylenes and present new method for describing hexagonal systemby corresponding a simple graph...

The teashirt (tsh) gene has dorso-ventral (DV) asymmetric functions in Drosophila eye development: promoting eye development in dorsal and suppressing eye development in ventral by Wingless mediated Homothorax (HTH) induction [Development 129 (2002) 4271]. We looked for DV spatial cues required by tsh for its asymmetric functions. The dorsal Iroquois-Complex (Iro-C) genes and Delta (Dl) are req...

Lemma 2.1 Let V a vector field on M and let T t F , t ∈ R be the functional representations of the diffeomorphisms Φt V : M→M of the one parameter group associated to the flow of V . If D is a linear partial differential operator then DV ◦D = D◦DV if and only if for any t ∈ R, T t F ◦D = D◦T t F . Proof Let p ∈ M and f ∈ C∞(M) be a smooth function. If V (p) = 0, then Φt V (p) = p and DV ( f )(p...

In this paper we give the expressions for computing the first geometric-arithmetic index of hexagonal systems and phenylenes and present new method for describing hexagonal system by corresponding a simple g...

OBJECTIVE To compare the prevalence of comorbidities, health care utilization, and costs between moderate-to-severe psoriasis (PsO) patients with comorbid psoriatic arthritis (PsA) and matched controls. METHODS Adults ages 18-64 years with concomitant diagnoses of PsO and PsA (PsO+PsA) were identified in the OptumHealth Reporting and Insights claims database between January 2007 and March 201...
