An exact, unified distributional characterization of statistics used to test linear hypotheses in simple regression models [PDF]
The Wald, likelihood ratio and Lagrange multiplier test statistics are commonly used to test linear restrictions in regression models. It is shown that for testing these restrictions in the classical regression model, the exact densities of these test ...

A Multidimensional Perspective on Network Conditions in Telesurgery
Advanced Intelligent Systems, EarlyView.A multidimensional framework systematically evaluates how combined network impairments influence telesurgical performance. By jointly analyzing latency, jitter, bandwidth, and packet loss, the proposed methodology identifies relevant network condition parameters and their interactions, supporting the design of reliable and safe telesurgical systems ...

Food insecurity and unemployment among immigrants in the United States
American Journal of Agricultural Economics, EarlyView.Abstract Immigrants can be more vulnerable to economic downturns and, during periods of economic hardship, more likely to experience food insecurity compared to natives. This study examines the differential effect of the unemployment rate on the probability of being food insecure among diverse groups of immigrant households relative to natives in the ...

Success of coastal sage scrub restoration is influenced by local adaptations of shrub species
American Journal of Botany, EarlyView.Abstract Premise Restoring plant communities is increasingly challenging with climate change. While practitioners have traditionally used local seed sources, many are recommending assisted migration, possibly from more extreme environments such as inland rather than coastal environments, for restoration.

Trace Elements Genetics: A Potential Role in Treatment‐Resistant Major Psychoses and Related Traits?
American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.ABSTRACT Trace elements are pivotal to key biological processes, with possible effects on psychopathology. We investigated the hypothesis of shared genetic factors between trace elements levels, treatment resistance and related traits. We used genome‐wide summary statistics for trace elements blood concentration, treatment‐resistant depression (TRD ...

Substrate‐Dependent Crosslinking by the Cytochrome P450 From Aminopyruvatide Biosynthesis
Angewandte Chemie, EarlyView.Substitutions in the aminopyruvatide precursor peptide altered the C─C linkage formed from a YLY motif by the P450 ApyO to a N─C linkage in a WLY motif. Moreover, constitutional isomers crosslinked by C─C and C─O linkages were formed from YYY or YWY motifs. ABSTRACT Cytochrome P450s catalyze an array of reactions including crosslinking of aromatic side
