The sugar sensing and carbon catabolite repression in Baker’s yeast Saccharomyces cerevisiae is governed by three major signaling pathways that connect carbon source recognition with transcriptional regulation. Here we present a screening method based on a non-invasive in vivo reporter system for real-time, single-cell screening of the sugar signaling state in S. cerevisiae in response to changing

Only a small fraction of the peptides inside a cell are eventually presented by HLA-I on the cell surface. The presented peptides have HLA-I allomorph-specific motifs and length restrictions. Tapasin influences HLA-I antigen presentation both qualitatively and quantitatively to different degrees depending on both peptide sequence and HLA-I allomorph. The tapasin-dependence in cellular context has

To dissect the genetic architecture of blood pressure and assess effects on target organ damage, we analyzed 128,272 SNPs from targeted and genome-wide arrays in 201,529 individuals of European ancestry, and genotypes from an additional 140,886 individuals were used for validation. We identified 66 blood pressure-associated loci, of which 17 were new; 15 harbored multiple distinct association sign

Large and persistent gaps in subnational public expenditure have important implications regarding growth, equity, and migration. In this context, we revisit the question of expenditure convergence across the American states to provide more nuanced evidence than found by a small number of previous studies. We employ a methodology due to Smeekes (Bootstrap sequential tests to determine the stationar

As a response to the inefficient practices and possibly misleading inferences resulting from the unit-by-unit application mostly found in the literature, the current paper develops a block bootstrap based panel predictability test procedure that accommodates multiple predictors. As an empirical illustration we consider emerging market sovereign risk where data are usually available across multiple

This paper tests the hypothesis that price discovery influences asset pricing. Our innovations are twofold. First, we estimate time-varying price discovery for a large number (21) of Islamic stock portfolios. Second, we test using a predictive regression model whether or not price discovery predicts stock excess returns. We find from both in-sample and out-of-sample tests that all 21 portfolio exc

Using the sharia-compliant measures, we compile a data set that spans January 1981 to December 2014 and contains 2577 Islamic stocks. Using as many as 12 financial and macroeconomic predictors, we discover strong evidence of both in-sample and out-of-sample return predictability. There is robust evidence of predictability only when U.S. stock returns are used as a predictor. We find that investing

Because of the fixed heterogeneity of their models, most panel unit root tests impose restrictions on the rate at which the number of time periods, T, and the number of cross-section units, N, go to infinity. A common example of such a restriction isN/T→0, which in practice means that T≫N, a condition that is not always met. In the current paper the heterogeneity is given a parsimonious random eff

A popular approach to factor-augmented panel regressions is the common correlatedeffects (CCE) estimator of Pesaran (Estimation and inference in large heterogeneous panels with a multifactor error structure. Econometrica 74, 967–1012, 2006). This paper points to a problem with the CCE approach that appears in the empirically relevant case when the number of factors is strictly less than the number

In this study steady-state natural convection for Al2O3 and CuO nanofluids inside different enclosures are numerically investigated. Natural convection is concerned due to a temperature difference between hot and cold surfaces. Rectangular and curved enclosures are investigated. The Boussinesq approximation is used to form the governing equations and the commercial software package ANSYS Fluent ve

Purpose s: The research aim is to develop a better design of auditory alerts that can improve air traffic controllers’ situation awareness. Method Participants are seventy-seven qualified Air Traffic Controllers. The experiment was conducted in the Air Traffic Control operational rooms of the Irish Aviation Authority at Shannon and Dublin. Participants were advised that the trials were in relation
