Smoothing of Bivariate Test Score Distributions: Model Selection Targeting Test Score Equating [PDF]

Journal of Educational and Behavioral Statistics
Observed-score test equating is a vital part of every testing program, aiming to make test scores across test administrations comparable. Central to this process is the equating function, typically estimated by composing distribution functions of the scores to be equated. An integral part of this estimation is presmoothing, where statistical models are

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

FEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Score Test for Marks in Hawkes Processes

SSRN Electronic Journal, 2019
Abstract A score statistic for detecting the impact of marks in a linear Hawkes self-exciting point process is proposed, with its asymptotic properties, finite sample performance, power properties using simulation , and application to real data presented.

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

FEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.
