Oscillation Tests for Delay Equations
Rocky Mountain Journal of Mathematics, 1999 The authors study the oscillatory behavior of delay equations of the form \[ x'(t)+ p(t)x(\tau(t))= 0,\quad t\geq T,\tag{1} \] with \(p,\tau\in C([T,\infty),[0,\infty))\), \(\tau(t)\) is decreasing, \(\tau(t)

SNSequate: Standard and Nonstandard Statistical Models and Methods for Test Equating
Journal of Statistical Software, 2014 Equating is a family of statistical models and methods that are used to adjust scores on two or more versions of a test, so that the scores from different tests may be used interchangeably.

Assessing the Impact of Characteristics of the Test, Common-items, and Examinees on the Preservation of Equity Properties in Mixed-format Test Equating [PDF]
, 2014 Preservation of equity properties was examined using four equating methods - IRT True Score, IRT Observed Score, Frequency Estimation, and Chained Equipercentile - in a mixed-format test under a common-item nonequivalent groups (CINEG) design.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

FEBS Letters, EarlyView.Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.
