The paper deals with caroline gardner cards sale the problem of determining the chemical balance weighing designs satisfying the criterion of D-optimality under assumption that the measurement errors are equal correlated and they have the same variances.The existence conditions and the form of the optimal design are given.Moreover, some constructio
Reciprocity is a fundamental principle of wave physics and directly relates to the symmetry in the transmission through a system when interchanging the input and output.The u11-200ps coherent transmission matrix (TM) is a convenient method to characterize wave transmission through general media.Here, we demonstrate the optical reciprocal nature of
The pseudopapillary pancreatic solid tumor (TPSP) is a rare malignancy typical of young adult women (only u11-200ps 12 pediatric cases from 2000 to 2009), it can recur and metastasize.The prognosis is usually good after radical surgical removal.We emphasize lmtbul the importance of TPSP in differential diagnosis of retrogastric, peripancreatic mass
ObjectivesExperiments using P2X3 knock-out mice or more general P2X receptor antagonists suggest that P2X3 receptors contribute to visceral hypersensitivity.We aimed to investigate the effect of the selective P2X3 antagonist A-317491 on visceral sensitivity under physiological conditions, during acute colitis and in the post-inflammatory phase of c
Background: Certain gene polymorphisms are suspected to contribute to the geographic-specific susceptibility of people to coronavirus disease 19 (COVID-19), which may be used as therapeutic targets.Accordingly, this review articulates suspected COVID-19 susceptibility genes to assist researchers and medical practitioners to formulate effective drug
