Advanced Science, EarlyView.Disuse‐induced muscle atrophy is driven by a non‐metabolic, nuclear function of the enzyme PFKFB3. Acting as a scaffold, PFKFB3 facilitates Nedd4‐mediated ubiquitination and degradation of the anti‐atrophy transcription factor JunB. Inhibiting this novel PFKFB3–Nedd4–JunB signaling axis stabilizes JunB and alleviates muscle wasting, revealing a highly ...

Multivariate Hypothesis Testing and Applications of Discriminant Analysis
, 2014 Analyzing large data sets is often time-consuming as many data sets depend on many variables, and multiple methods of analyzing such data sets are explored.

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‐

Multivariate L1 Statistical Methods: The Package MNM [PDF]
In the paper we present an R package MNM dedicated to multivariate data analysis based on the L_1 norm. The analysis proceeds very much as does a traditional multivariate analysis. The regular L_2 norm is just replaced by different L_1 norms, observation

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 ...

THE FORMAL LOGIC OF TESTING STRUCTURAL CHANGE IN MEAT DEMAND: A METHODOLOGICAL ANALYSIS [PDF]
In the past two decades, the profession has expended valuable resources testing structural change in meat demand with mixed results. Overlooked to date is a fundamental methodological problem that transcends all of the methods of testing for structural ...

Students' understanding of hypothesis testing in introductory tertiary-level statistics [PDF]
, 1999 The research study investigates students' understanding of hypothesis testing by exploring their conceptual and procedural knowledge of the topic.\ud \ud Eighteen volunteer students from a large introductory service subject in statistics were interviewed

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.

A note on testing the covariance matrix for large dimension [PDF]
We consider the problem of testing hypotheses regarding the covariance matrix of multivariate normal data, if the sample size s and dimension n satisfy lim [n,s→∞] n/s = y. Recently, several tests have been proposed in the case, where the sample size and
