Metastability threshold for anisotropic bootstrap percolation in three dimensions [PDF]

, 2011
In this paper we analyze several anisotropic bootstrap percolation models in three dimensions. We present the order of magnitude for the metastability threshold for a fairly general class of models. In our proofs we use an adaptation of the technique of dimensional reduction. We find that the order of the metastability threshold is generally determined

An Explainable Multimodal Artificial Intelligence Model Integrating Histopathological Microenvironment and EHR Phenotypes for Germline Genetic Testing in Breast Cancer

Advanced Science, EarlyView.
This study presents an explainable multimodal AI model, MAIGGT (Multimodal Artificial Intelligence Germline Genetic Testing), that combines whole‐slide histopathology with clinical data for accurate germline BRCA1/2 mutation prescreening. By integrating digital pathology and EHR phenotypes, MAIGCT enables cost‐effective, scalable hereditary breast ...

Bootstrapping Long-Run Covariance of Stationary Functional Time Series

Forecasting
A key summary statistic in a stationary functional time series is the long-run covariance function that measures serial dependence. It can be consistently estimated via a kernel sandwich estimator, which is the core of dynamic functional principal ...

Phenotypic stability via ammi model with bootstrap re-sampling Estabilidade fenotípica através da reamostragem “bootstrap” no modelo AMMI

Pesquisa Florestal Brasileira, 2010
Reliable evaluation of the stability of genotypes and environment is of prime concern to plant breeders, but the lack of a comprehensive analysis of the structure of the GE interaction has been a stumbling block to the recommendation of varieties.

Model-free Bootstrap for a General Class of Stationary Time Series [PDF]

arXiv, 2019
A model-free bootstrap procedure for a general class of stationary time series is introduced. The theoretical framework is established, showing asymptotic validity of bootstrap confidence intervals for many statistics of interest. In addition, asymptotic validity of one-step ahead bootstrap prediction intervals is also demonstrated.

Computationally efficient approximation for the double bootstrap mean bias correction [PDF]

We propose a computationally efficient approximation for the double bootstrap bias adjustment factor without using the inner bootstrap loop. The approximation converges in probability to the population bias correction factor.

Single‐Cell Transcriptome Reveals Aquaporin‐Mediated Carbon Nanosol‐Induced Growth Promotion of Plants

Advanced Science, EarlyView.
Carbon nanosol (CNS) exhibits rapid root penetration capacity, enhancing plant growth through boosting stomatal density and antioxidative enzyme activity. Single‐cell transcriptomic profiling uncovers cell type‐specific gene expression patterns and developmental trajectories during CNS‐mediated growth promotion.
