A convolution test equation for double delay integral equations

open access: yesJournal of Computational and Applied Mathematics, 2009
The authors study a convolution test equation for double delay integral equations of the type \[ y(t)=f(t)+\int^{t-\tau_{1}} _{t-\tau_{2}} k(t-\tau) g(y(\tau)) d\tau, t\in[\tau_{2},T]. \] They introduce discrete quadrature methods for the problem discussed and describe their convergence.

A TEST OF THE NULL EQUATION FOR FUNCTIONAL ANTAGONISM [PDF]

open access: yesBritish Journal of Pharmacology, 1981
The quantitative model for functional antagonism and synergism has been tested by studying its ability to fit data obtained from the functional antagonism of (−)‐isoprenaline by muscarinic agonists on guinea‐pig isolated atria. The general form of the null equation has been shown to fit the experimental curves satisfactorily.

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Longitudinal measurement of growth in vocabulary size using Rasch-based test equating

open access: yesLanguage Testing in Asia, 2022
The purpose of this study is to equate and further validate three forms of the vocabulary size test (VST) created by Aizawa and Mochizuki (2010). These three forms, VST 1, 2, and 3, were administered to a cohort of 189 high school students ranging in age

Linking the Scores of the Montreal Cognitive Assessment 5-min and the interRAI Cognitive Performance Scale in Older Adults With Mild Physical or Cognitive Impairment

open access: yesFrontiers in Psychiatry, 2021
Background: Bridging scores generated from different cognitive assessment tools is necessary to efficiently track changes in cognition across the continuum of care. This study linked scores from the Montreal Cognitive Assessment-5 min (MoCA 5-min) to the

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Rab14 regulates the transport of human papillomavirus to the trans‐Golgi network for infectious cell entry

open access: yesFEBS Letters, EarlyView.
This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.

Is pseudo-equivalent groups equating via minimum discriminant information adjustment effective? Evidence from simulation and real data

open access: yesFrontiers in Education
The traditional way to linking different forms of test typically uses common (or randomly equivalent) examinees or items. When common examinees or items are unavailable due to test properties or administrative restrictions, equating with pseudo ...

Equational axioms of test algebra [PDF]

open access: yes, 1998
We have axiomatized test algebra equations and achieved a finite equational axiomatization relative to Kleene algebra. The previous section showed that the Kleene algebra component cannot be replaced by a finite set of test algebra equations.
