Decreased variability of small-world propensity during non-response tasks in schizophrenia

open access: yesNeuroImage: Reports
Functional disconnection is thought to underlie schizophrenia and is often studied by characterizing the small-worldness of networks derived from electroencephalogram (EEG) recordings.

Questionnaire Design and Response Propensities for Labour Income Microdata

open access: yes, 2022
AbstractThe income question in household surveys is one of the most socially sensitive constructs. Two problems that arise with social sensitivity concern the probability of obtaining a response and the type of response provided. In survey error terms, this translates into an important relationship between questionnaire design (construct validity) and ...

Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding

open access: yesFEBS Letters, EarlyView.
In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.

On the Impact of Response Patterns on Survey Estimates from Access Panels

open access: yesSurvey Research Methods, 2013
Household and individual surveys increasingly gain importance in policy support and other areas. However, the raising number of surveys leads to reduced response rates.

Nonparametric Estimators of Dose-Response Functions [PDF]

open access: yes
We propose two semiparametric estimators of the dose-response function based on spline techniques. Under uncounfoundedness, the generalized propensity score can be used to estimate dose-response functions (DRF) and marginal treatment effect functions. In

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

open access: yesFEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

Neural Responses to Truth Telling and Risk Propensity under Asymmetric Information

open access: yesPLOS ONE, 2015
Trust is multi-dimensional because it can be characterized by subjective trust, trust antecedent, and behavioral trust. Previous research has investigated functional brain responses to subjective trust (e.g., a judgment of trustworthiness) or behavioral trust (e.g., decisions to trust) in perfect information, where all relevant information is available

Metastatic niche shaped by host factors influences disseminated cancer cell fate

open access: yesFEBS Letters, EarlyView.
Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

Invisible but not inaccessible—Revealing transient oligomers formed by intrinsically disordered proteins with solution NMR and complementary methods

open access: yesFEBS Letters, EarlyView.
Transient oligomers formed by intrinsically disordered proteins may be ‘invisible’ to direct detection yet remain accessible to solution NMR through equilibrium‐exchange measurements and pressure‐jump experiments. Complementary methods report on mass, stoichiometry, selected distance distributions, morphology, and internal packing.
