Inferring Covariances for Probabilistic Programs [PDF]
arXiv, 2016 We study weakest precondition reasoning about the (co)variance of outcomes and the variance of run-times of probabilistic programs with conditioning. For outcomes, we show that approximating (co)variances is computationally more difficult than approximating expected values.

Recent Estimates of Time-Variation in the Conditional Variance and in the Exchange Risk Premium [PDF]
The optimal-diversification model of investors' portfolio behavior can give a linear relationship between the exchange risk premium and the conditional exchange rate variance.

Altered Brain‐Behavior Association During Resting State is a Potential Psychosis Risk Marker
Advanced Science, EarlyView.The study detects a potential multimodal biomarker that can be promising for identifying early markers of psychosis. It shows a consistent brain‐behavior association between a circuit of interconnected regions and executive function in neurotypical controls and individuals at various stages of psychosis.

Which ergodic averages have finite asymptotic variance? [PDF]
arXiv, 2016 We show that the class of $L^2$ functions for which ergodic averages of a reversible Markov chain have finite asymptotic variance is determined by the class of $L^2$ functions for which ergodic averages of its associated jump chain have finite asymptotic variance.

Advanced Science, EarlyView.AAV2.7m8 serotype combined with the gfaABC1D promoter targets infection of supporting cells (SCs). AAV2.7m8‐gfaABC1D‐Gjb2 administration to mice results in excessive immune responses. The combination of AAV2.7m8‐gfaABC1D‐Gjb2 with dexamethasone (DEX) shows a synergistic effect and enhances the gene therapy effect in a conditional Cx26 null mice model ...

Empirical Variance Minimization with Applications in Variance Reduction and Optimal Control [PDF]
arXiv, 2017 We study the problem of empirical minimization for variance-type functionals over functional classes. Sharp non-asymptotic bounds for the excess variance are derived under mild conditions. In particular, it is shown that under some restrictions imposed on the functional class fast convergence rates can be achieved including the optimal non-parametric ...

Bilirubin Targeting WNK1 to Alleviate NLRP3‐Mediated Neuroinflammation
Advanced Science, EarlyView.At physiological concentrations, bilirubin binds to the kinase domain of WNK1, thereby augmenting its activity and facilitating the phosphorylation of downstream SPAK/OSR1. This phosphorylation inhibits KCC2 activity, leading to elevate intracellular chloride levels in neurons.

Posterior Variance Analysis of Gaussian Processes with Application to Average Learning Curves [PDF]
arXiv, 2019 The posterior variance of Gaussian processes is a valuable measure of the learning error which is exploited in various applications such as safe reinforcement learning and control design. However, suitable analysis of the posterior variance which captures its behavior for finite and infinite number of training data is missing.

Advanced Science, EarlyView.Pinoresinol diglucoside, a bioactive component extracted from traditional Chinese medicine, attenuates cisplatin‐induced ototoxicity in vivo and in vitro. The protective effect is achieved by downregulation of Socs1. The present study is the first to investigate the expression and function of Socs1 in inner ear, which is known to promote ferroptosis ...
