Improving inference of Gaussian mixtures using auxiliary variables [PDF]

Statistical Analysis and Data Mining: The ASA Data Science Journal, 2015
AbstractExpanding a lower‐dimensional problem to a higher‐dimensional space and then projecting back is often beneficial. This article rigorously investigates this perspective in the context of finite mixture models, specifically how to improve inference for mixture models by using auxiliary variables. Despite the large literature in mixture models and

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

FEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Cube-Attack-Like Cryptanalysis of Round-Reduced Keccak Using MILP

IACR Transactions on Symmetric Cryptology, 2018
Cube-attack-like cryptanalysis on round-reduced Keccak was proposed by Dinur et al. at EUROCRYPT 2015. It recovers the key through two phases: the preprocessing phase for precomputing a look-up table and online phase for querying the output and getting ...

Monitoring process variability using auxiliary information [PDF]

Computational Statistics, 2007
A construction of Shewhart-type control charts is considered for the changes of variance of a controlled variable \(Y\) in the case when some auxiliary variable \(X\) is also observed. Bivariate normality of \((X,Y)\) is assumed. The chart is based on a regression-type estimate for the variance of \(Y\) by observations on \(X\). The central line, lower

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

FEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Split Sampling: Expectations, Normalisation and Rare Events [PDF]

, 2013
In this paper we develop a methodology that we call split sampling methods to estimate high dimensional expectations and rare event probabilities. Split sampling uses an auxiliary variable MCMC simulation and expresses the expectation of interest as an ...

Updating Latent Class Imputations with External Auxiliary Variables [PDF]

Structural Equation Modeling: A Multidisciplinary Journal, 2018
Latent class models are often used to assign values to categorical variables that cannot be measured directly. This "imputed" latent variable is then used in further analyses with auxiliary variables. The relationship between the imputed latent variable and auxiliary variables can only be correctly estimated if these auxiliary variables are included in

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

FEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

A Comparative Study of New Ratio-Type Family of Estimators Under Stratified Two-Phase Sampling

Mathematics
Two-phase sampling is a useful technique for sample surveys, particularly when prior auxiliary data is not accessible. The ranks of the auxiliary variable often coincide with those of the research variable when two variables are correlated.
