Due to cell-to-cell variability and asymmetric cell division, cells in a synchronized population lose synchrony over time. As a result, time-series measurements from synchronized cell populations do not reflect the underlying dynamics of cell-cycle processes. Here, we present a branching process deconvolution algorithm that learns a more accurate view of dynamic cell-cycle processes, free from ...
A method is presented whereby the WKB expression for tunneling frequencies permits correlation of the.se frequencies for members of homologous series of molecules. The necessary data required are the tunneling rate for one member of the series, and structural parameters and vibrational frequencies for all members of interest. The method is applied to NDz, NF" PH" and AsH" using NH. as the molec...
Yuchanyan Cave in Daoxian County, Hunan Province (People's Republic of China), yielded fragmentary remains of 2 or more ceramic vessels, in addition to large amounts of ash, a rich animal bone assemblage, cobble and flake artifacts, bone tools, and shell tools. The artifacts indicate that the cave was a Late Paleolithic foragers' camp. Here we report on the radiocarbon ages of the sediments bas...
The metal free, single amino acid-catalyzed asymmetric desymmetrization (ADS) of meso-compounds with nitrosobenzene has been investigated using DFT. In this communication, we describe the role of electrostatic and dipole-dipole interactions in amino acid-catalyzed reactions, which has not previously been invoked in discussions of these important reactions.
In this paper role of sex as a moderator variable in effectiveness of attractive defeated asymmetric and defeated symmetric choices on consumers’ choice in shopping decision. This is functional descriptive analytic research. The statistical population is 380 male and female students of Arak universities using Morgan Table. The sampling method is random. The research tool is questionnair...
Introduction Abnormal neural impulses in the nervous system may lead to various diseases and disabilities. High frequency alternating currents (HFAC) has been used to block the propagation of such impulses and improve the symptoms or disabilities. The technique is safe, reversible, and relatively selective, and its reliability, the optimum stimulation parameters, and elimination of the onset re...
This study investigated the asymmetric effects of financial instability shocks on economic growth and monetary policy shocks on financial instability in Iran. For this purpose,data 1991:3 to 2017:1 and nonlinear auto-regressive distributed lag (NARDL) approach has been used. For this purpose, three models have been estimated. In the first model, the asymmetric effects of fiscal instability shoc...
Polarity formation is central to leaf morphogenesis, and several key genes that function in adaxial-abaxial polarity establishment have been identified and characterized extensively. We previously reported that Arabidopsis thaliana ASYMMERTIC LEAVES1 (AS1) and AS2 are important in promoting leaf adaxial fates. We obtained an as2 enhancer mutant, asymmetric leaves enhancer3 (ae3), which demonstr...
