Testing the martingale difference hypothesis using integrated regression functions. [PDF]
An omnibus test for testing a generalized version of the martingale difference hypothesis (MDH) is proposed. This generalized hypothesis includes the usual MDH, testing for conditional moments constancy such as conditional homoscedasticity (ARCH effects)

Brain Network Dynamics of Local and Global Predictive Processing in Aging
Advanced Science, EarlyView.Separation of concurrent whole‐brain networks in source‐reconstructed magnetoencephalography (MEG) data suggests that healthy aging reorganizes, rather than uniformly attenuates, neural responses elicited from hierarchical auditory violations. Enhanced early sensory deviance processing alongside reduced higher‐order cognitive responses suggests a large‐

Advanced Science, EarlyView.In this work, we present a bile‐based memristor hardware framework that enables direct, label‐free identification of cholelithiasis and gallbladder cancer at the device level. The Ag/bile/FTO memristor features stable resistive switching and disease‐specific electrical responses, providing a conceptual foundation for circuits and an integrated ERCP ...

An interactive tool for semi-automatic feature extraction of hyperspectral data
Open Geosciences, 2016 The spectral reflectance of the surface provides valuable information about the environment, which can be used to identify objects (e.g. land cover classification) or to estimate quantities of substances (e.g. biomass).

ERα–PADI4–CXCL8 Axis Drives MDSC‐Mediated Immune Evasion in Anaplastic Thyroid Carcinoma
Advanced Science, EarlyView.MAPK‐driven ligand‐independent ERα activation drives PADI4 transcription and translation. This enzyme then modifies CXCL8 chemokines through citrullination, generating a potent chemoattractant gradient specifically for myeloid‐derived suppressor cells.

Bootstrap methods for multivariate hypothesis testing
, 2017 The nonparametric and parametric bootstrap methods for multivariate hypothesis testing are developed. They are used to approximate the null distribution of the test statistics proposed by Duchesne and Francq (2015), resulting in bootstrap testing ...

Advanced Science, EarlyView.The schematic diagram depicts a compartmentalized anti‐ferroptotic defense mechanism mediated by GSTA4. GSTA4 is upregulated and localizes to the cytoplasm in ENZR cells, where it detoxifies 4‐HNE via a non‐canonical GSH‐dependent pathway. Under oxidative stress, GSTA4 translocates to mitochondria, interacts with PGAM5, and blocks Drp1 Ser637 ...

Advanced Science, EarlyView.This study reveals that 5'tiRNA‐Gln interacts with hnRNPC to promote IGF1R liquid‐liquid phase separation, which drives ERK1/2 signaling activation, EMT, and breast cancer bone metastasis. These findings highlight a novel mechanism of breast cancer bone metastasis and potential therapeutic target in metastatic breast cancer.
