Conditions leading to the observation of a difficulty effect and its consequence for confirmatory factor analysis

, 2021
Psychometric research has posited that difficulty effects related to item-level input for factor analysis serves as the precondition for observing a difficulty factor. Two studies are reported that investigated and confirmed this hypothesis.

Epigenetic heterogeneity and plasticity in therapy‐induced tumor states through single‐cell multi‐omics

Molecular Oncology, EarlyView.
Single‐cell multi‐omics reveals epigenetic heterogeneity across therapy‐adaptive tumor states, including quiescent/dormant, drug‐tolerant persister, and EMT‐like phenotypes. By linking regulatory features with state‐associated biomarkers, these approaches inform biomarker‐guided therapeutic strategies for evolving tumors.

Identifying the task characteristics that predict children's construction task performance [PDF]

, 2010
Construction tasks form a major part of children’s play and can be linked to achievement in maths and science. However there is a lack of understanding of construction task ability and development.

Promiscuous stimulation of HSP70 ATPase activity by parasite‐derived J‐domains

FEBS Open Bio, EarlyView.
The malaria parasite Plasmodium falciparum exports three highly homologous yet functionally divergent J‐domain proteins into human erythrocytes. Here, we show that J‐domains isolated from all three proteins effectively stimulate the ATPase activity of both endogenous host and exported parasite HSP70 chaperones.

Data-limited manipulations of T1 difficulty influence the attentional blink

, 2007
When two targets are embedded in a temporal stream of distractors, second-target identification is initially impaired and then gradually improves as intertarget interval lengthens (attentional blink; AB).

YlmG1 is localized exclusively to the chloroplast envelope membrane and is involved in preprotein translocation in Arabidopsis thaliana

FEBS Open Bio, EarlyView.
Cytosolically synthesized chloroplast preproteins are translocated across the outer and inner envelope membranes through translocons called TOC and TIC, respectively. In green algae and plants, the TIC core is composed of essential membrane proteins, Tic12, Tic20, and Tic214.

RELATION BETWEEN VAULT DIFFICULTY VALUES AND BIOMECHANICAL PARAMETERS IN MEN'S ARTISTIC GYMNASTICS

Science of Gymnastics Journal, 2011
The aim of the paper is to define which biomechanical parameters explain and define the difficulty vault value. The study sample included 64 vaults from the Code of Points (COP) of the International Gymnastics Federation (FIG, 2009).
