Removing Atmospheric Turbulence from Ground-based Astrometry with Fast Correlation Function Measurements

The Astronomical Journal
We present a code that removes ∼90% of the variance in astrometric measurements caused by atmospheric turbulence, by using Gaussian process regression (GPR) to interpolate the turbulence field from the positions of stars measured by Gaia to the positions

基于多输入高斯过程回归的震级快速估算方法

Dizhen xuebao
为充分利用初至地震波中与震级相关的信息，提高震级估算精度，本文提出了一种震级快速估算方法（GPR），该方法将初至地震波在时域、频域和时频域中的10个特征参数输入高斯过程回归模型实现震级估算。利用日本的大量地表强震记录对GPR方法进行训练和测试，并与最大卓越周期\begin{document}${\tau ^{\max }_{\mathrm{p}}} $\end{document}方法和位移幅值P d方法进行了对比。结果表明，GPR方法在有震源距和无震源距两种情况下，估算震级的准确性均显著好于\begin{

Inference for Adaptive Time Series Models: Stochastic Volatility and Conditionally Gaussian State Space Form [PDF]

In this paper we replace the Gaussian errors in the standard Gaussian, linear state space model with stochastic volatility processes. This is called a GSSF-SV model.

Polymorph‐Specific Electronic Transduction in WO3 during Molecular Sensing

Advanced Materials, EarlyView.
Metal‐oxide polymorphs with similar surface chemistry can nevertheless exhibit distinct sensing properties. In γ‐ and ε‐WO3, analyte adsorption appears comparable; yet, only ε‐WO3 induces a pronounced lattice electronic perturbation that accommodates charge in sub‐conduction band minimum states.
