Comparative evaluation of noncanonical amino acids as site‐specific NMR probes for the complex of E. coli SSB with single‐stranded DNA without isotope labelling

open access: yesThe FEBS Journal, EarlyView.
Genetic encoding of noncanonical amino acids (ncAA) enables their site‐specific installation in proteins. This work compares the nuclear magnetic resonance (NMR) performance of different ncAAs in a large protein−DNA complex (~ 100 kDa) without isotope labelling. The ncAAs deliver readily detectable NMR signals in the complex between E.

External structures at the nest‐site predict asymmetric architecture of nests in a mud‐building bird

open access: yesIbis, EarlyView.
In the animal kingdom, nests are essential structures and textbook examples of extended phenotypes. However, the relationship between builders, nest traits and the nest‐site remains poorly understood. We indirectly examine whether structures in the nest‐site influence nest‐building behaviour, specifically focusing on their effect on nest architecture ...

A new method for detecting differential item functioning in the Rasch model [PDF]

open access: yes
Differential item functioning (DIF) can lead to an unfair advantage or disadvantage for certain subgroups in educational and psychological testing. Therefore, a variety of statistical methods has been suggested for detecting DIF in the Rasch model.

Does Multidimensionality Cause DIF?

open access: yesANIMA Indonesian Psychological Journal, 2018
The differential item functioning (DIF) of an item that initially assumed unidimensional is frequently attributed to the assumption of multidimensionality. Therefore, it is important to test the assumption that multidimensionality causes an item to be functionally different between the disadvantaged group (i.e. focal group) and the benefited group (i.e.

The Development and Validation of the Chinese Vocabulary Levels Test

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT In response to the increasing need for effective Chinese vocabulary assessments, this study developed the Chinese Vocabulary Levels Test (CVLT), a test designed for intermediate‐level Chinese as a second or foreign language (CSL/FL) learners, based on the vocabulary lists (levels 4–6) from the Chinese Proficiency Grading Standards for ...

Mucous Membrane Pemphigoid After Anti‐PD‐1 Therapy: Risk‐Stratified Management and Treatment Outcomes

open access: yesInternational Journal of Dermatology, EarlyView.
ABSTRACT Mucous membrane pemphigoid (MMP) following anti‐programmed cell death‐1 (PD‐1) therapy is rare but increasingly reported. Management of high‐ and low‐risk MMP in this setting and the potential oncologic trade‐offs remain poorly defined. We performed a narrative synthesis of all published cases of anti‐PD‐1‐associated MMP, following MEDLINE ...
