Abstract Online task assignment is one of the core research issues spatio-temporal crowdsourcing technology. The current researches on minimizing travel cost all focus scenario two objectives (task requesters and workers). This paper proposes a two-stage framework (GH) based Greedy algorithm Hungarian for three-objective online to minimize cost. In order further optimize efficiency average cost...

This article introduces the concept of weak sharp minima for convex interval-valued functions. To solve constrained and unconstrained IOPs by WSM, we provide primal dual characterizations set WSM. The characterization is given in terms gH-directional derivatives. On other hand, to derive characterizations, propose notions support function a subset $$I({\mathbb {R}})^{n}$$ gH-subdifferentiabilit...

In this paper, we study fuzzy calculus in two main branches differential and integral.  Some rules for finding limit and $gH$-derivative of $gH$-difference, constant multiple of two fuzzy-valued functions are obtained and we also present fuzzy chain rule for calculating  $gH$-derivative of a composite function.  Two techniques namely,  Leibniz's rule and integration by parts are introduced for ...

fish genome contains two copies of growth hormone (gh-1 and gh-2) as a result of duplication process during evolution. the aim of this study was to distinguish gh-1 from gh-2 genes in rutilus kutum (mahi sefid) from the caspian sea using sequencing techniques and application of specific restriction enzymes for these loci. for this purpose, five fish were randomly selected and samples for dna ex...

Growth hormone (GH) secretion, controlled principally by a GH-releasing hormone (GHRH) and GH release-inhibiting hormone [somatostatin (SRIF)] displays vivid sexual dimorphism in many species. We hypothesized that relatively small differences within a dynamic core GH network driven by regulatory interactions among GH, GHRH, and SRIF explain the gender contrast. To investigate this notion, we im...

Growth hormone (GH) is secreted in a pulsatile pattern to promote body growth and metabolism. GH exerts its function by activating several signaling pathways, including JAK2/STAT and MEK/ERK. ERK1/2 activation by GH plays important roles in gene expression, cell proliferation, and growth. We previously reported that in rat H4IIE hepatoma cells after an initial GH exposure, a second GH exposure ...

Expression of growth hormone (GH) and GH receptor (GHR) genes in the bursa of Fabricius of chickens suggests that it is an autocrine/paracrine site of GH production and action. The cellular localization of GH and GH mRNA within the bursa was the focus of this study. GH mRNA was expressed mainly in the cortex, comprised of lymphocyte progenitor cells, but was lacking in the medulla where lymphoc...

in this study the genetic polymorphism of growth hormone (gh) gene as a candidate gene in livestock was investigated. blood samples were randomly collected from 34 alpine and 42 saanen goats. dna was extracted from blood samples and a 365 bp region of exon 5 of the gh genewas amplified by polymerase chain reaction (pcr). pcr products were analyzed using single strand conformation polymorphism (...

Proof. We consider the two cases: either g ∈ H or g ∈ G−H. Case 1 Suppose g ∈ H. Then for any gh ∈ gH, gh ∈ H. This implies gH ⊆ H. Now, let h be any element of H. Then h = (gg−1)h = g(g−1h), and g−1h ∈ H because g−1 and h are both in the subgroup H. It follows that h ∈ gH and H ⊆ gH. Therefore, gH = H. It can be similarly shown that Hg = H. This means gH = Hg and H £ G by Lemma 2.5.1 from clas...
