The fumigant methyl iodide (MeI, iodomethane) is considered a promising alternative to methyl bromide (MeBr) for soil-borne pest control in high-cash-value crops. However, the high vapor pressure of MeI results in emissions of a significant proportion of the applied mass into the ambient air, and this may lead to pollution of the environment. Integrating the application of certain agrochemicals...

In mitosis and meiosis, cohesion is maintained at the centromere until sister-chromatid separation. Drosophila MEI-S332 is essential for centromeric cohesion in meiosis and contributes to, though is not absolutely required for, cohesion in mitosis. It localizes specifically to centromeres in prometaphase and delocalizes at the metaphase-anaphase transition. In mei-S332 mutants, centromeric sist...

Similar to the evolution from wired Internet to mobile Internet (MI), the growing demand of power delivery anywhere and anytime appeals for power grid transformation from wired to mobile domain. We propose here the next generation of power delivery network – mobile energy internet (MEI) for wireless energy transfer within a mobile range from several meters to tens of meters. MEI will be a signi...

Changes in myocardial electrical impedance (MEI) and physiological end points have been correlated during acute ischemia. However, the importance of MEI's early time course is not clear. This study evaluates such significance, by comparing the temporal behavior of MEI during acute total occlusion of the left anterior descending coronary artery in anesthetized humans, dogs, and pigs. Here, inter...

Because of its popularity as an ornamental plant in East Asia, mei (Prunus mume Sieb. et Zucc.) has received increasing attention in genetic and genomic research with the recent shotgun sequencing of its genome. Here, we performed the genome-wide characterization of simple sequence repeats (SSRs) in the mei genome and detected a total of 188,149 SSRs occurring at a frequency of 794 SSR/Mb. Mono...

The correlations between GBS, dengue, Multivariate El Nino Southern Oscillation Index (MEI) and local meteorological data were explored by the Spearman Rank correlations and cross-correlations between these time series. Poisson regression models were fitted to identify nonlinear associations between MEI and dengue. Cross wavelet analysis was applied to infer potential non-stationary oscillating...

Mutations in the Drosophila mei-S332 gene cause premature separation of the sister chromatids in late anaphase of meiosis I. Therefore, the mei-S332 protein was postulated to hold the centromere regions of sister chromatids together until anaphase II. The mei-S332 gene encodes a novel 44 kDa protein. Mutations in mei-S332 that differentially affect function in males or females map to distinct d...

The recombination and repair defective mutant, mei-41, exhibits three rather striking effects on the genetic properties and chromosomal stability of rDNA in Drosophila. First, mei-41 inhibits rDNA magnification. However, mei-9, another recombination and repair defective mutation has no similar effect. This indicates that magnification requires some, but not all, of the gene products necessary f...

Medicare payments for physician services under Part B were historically restrained by capping prevailing charges using the Medicare Economic Index (MEI). The MEI, an input price index for physician services that incorporates an adjustment for economywide labor productivity, has not undergone a major revision since 1975. The MEI is an important determinant of the annual volume performance standa...

abstract The key to the method of measured equation of invariance (MEI) is the postulate: \the MEI is invariant to the excitation". In this paper, we proved that the MEI is independent of the excitation with the error bounded by O(h 2), where h is the discretization step. We also proved that the consistent condition jjLL?M=h 2 jj = ", where L is the partial diierential operator, and M the equiv...
