Species with restricted distributions make up the vast majority of biodiversity. Recent evidence suggests that Drosophila species with restricted tropical distributions lack genetic variation in the key trait of desiccation resistance. It has therefore been predicted that tropically restricted species will be limited in their evolutionary response to future climatic changes and will face higher...

Abstract We deduce the asymptotic behavior of transition densities for a large class spectrally one-sided Lévy processes unbounded variation satisfying mild condition imposed on second derivative Laplace exponent or, equivalently, real part characteristic exponent. also provide sharp two-sided estimates density when restricted additionally to without Gaussian component.

stable crystalline phosphorus ylides are obtained in excellent yields from the 1:1:1 addition reactionbetween hydantoins or thiohydantoins and dialkyl acetylenedicarboxylates in the presence oftriphenylphosphine. these phosphoranes undergo smooth intramolecular wittig reaction followedby an electrocyclic ring opening to produce dialkyl (e)-2-(2,5-dihydro-5,5-diaryl-2-thioxo-1h-imidazol-4-yl)fum...

conclusions considering that neuronal function highly depends on environmental conditions, any adverse alteration may affect the function and morphology of neurons. in this regard, our results showed the adverse effects of protein malnutrition on the morphology of the purkinje cells of cerebellum. results the low-protein group did not gain weight as much as control group (p < 0.05). the diamete...

HIV-1 specific HLA-B-restricted CD8+ T cell responses differ from HLA-C-restricted responses in antiviral effectiveness. To investigate possible reasons for these differences, we characterized the frequency and polyfunctionality of immmunodominant HLA-B*57/B5801- and HLA-Cw*07-restricted CD8+ T cells occurring concurrently in nine study subjects assessing IFN-gamma, TNF-alpha, IL-2, MIP-1beta, ...

This article presents a simulation study over a small supply chain, where the amount of work-in-process (WIP) is restricted. The supply chain consists of five linked machines, or production facilities, with stochastic operation times. A number of test cases are made where the number of jobs in the machines and the buffer areas are restricted. The restrictions are designed both in the Kanban way...
