Unit Root Model Selection [PDF]

open access: yes
Some limit properties for information based model selection criteria are given in the context of unit root evaluation and various assumptions about initial conditions. Allowing for a nonparametric short memory component, standard information criteria are

Why human connection is the true metric of research success

open access: yesFEBS Open Bio, EarlyView.
Human‐centred mentorship can be shaped by mentor attributes, actions, intrinsic drive and career ambition. Drawing on reflections across Singapore and France, as well as workshop insights from FEBS‐IUBMB ENABLE 2024, this article shows that human‐centred mentorship creates the conditions for sustainable growth, well‐being and retention in research ...

Saddlepoint Approximations for Optimal Unit Root Tests [PDF]

open access: yes
This paper provides a (saddlepoint) tail probability approximation for the distribution of an optimal unit root test. Under restrictive assumptions, Gaussianity and known covariance structure, the order of error of the approximation is given.

Refinement of amino‐acid conformation vs. difference density maps in time‐resolved serial femtosecond crystallography data analysis

open access: yesFEBS Open Bio, EarlyView.
The dFoCC pipeline starts with observed DED and resting‐state coordinates, which are then used to generate a library of triggered states. Correlation analysis of the calculated DED features of each candidate vs observed DED permits quantitative evaluation of candidate structural quality.

On Buekenhout-Metz unitals of even order

open access: yesEuropean Journal of Combinatorics, 1992
A unital is a \(2-(n^ 3+1,n+1,1)\) design. The classical example of a unital is the set of absolute points in a projective plane \(\text{PG}(2,n^ 2)\) with respect to a unitary polarity, blocks being the sets of points on secant lines. A class of unitals, including the classical ones, can be constructed inside \(\text{PG}(2,n^ 2)\) by a method due to ...

UiO‐66 metal–organic frameworks in biomedicine: From structural tunability to bioimaging, photodiagnostics, and photodynamic cancer therapy

open access: yesFEBS Open Bio, EarlyView.
UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

Lag Length Selection for Unit Root Tests in the Presence of Nonstationary Volatility [PDF]

open access: yes
A number of recently published papers have focused on the problem of testing for a unit root in the case where the driving shocks may be unconditionally heteroskedastic.

isocir: An R Package for Constrained Inference Using Isotonic Regression for Circular Data, with an Application to Cell Biology

open access: yesJournal of Statistical Software, 2013
In many applications one may be interested in drawing inferences regarding the order of a collection of points on a unit circle. Due to the underlying geometry of the circle standard constrained inference procedures developed for Euclidean space data are
