Development and validation of an instrument to measure the Micro-Learning Environment of Students (MLEM)

BMC Medical Education, 2023
Background There are multiple instruments to measure different learning environments but no valid and reliable instrument is present for measuring the micro-learning environment. This study aimed to develop and validate an instrument to measure the micro-

On the complexity and the information content of cosmic structures

, 2016
The emergence of cosmic structure is commonly considered one of the most complex phenomena in Nature. However, this complexity has never been defined nor measured in a quantitative and objective way.

Artificial Sequences and Complexity Measures [PDF]

, 2005
In this paper we exploit concepts of information theory to address the fundamental problem of identifying and defining the most suitable tools to extract, in a automatic and agnostic way, information from a generic string of characters.

Cell wall target fragment discovery using a low‐cost, minimal fragment library

FEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

On the complexity of quantum field theory

Journal of High Energy Physics
We initiate a study of the complexity of quantum field theories (QFTs) by proposing a measure of information contained in a QFT and its observables. We show that from minimal assertions, one is naturally led to measure complexity by two integers, called ...

Improved measurement of tinnitus severity: Study of the dimensionality and reliability of the Tinnitus Handicap Inventory.

PLoS ONE, 2020
ObjectiveThe Tinnitus Handicap Inventory (THI) is widely used in clinical practice and research as a three-dimensional measure of tinnitus severity. Despite extensive use, its factor structure remains unclear.

Measuring needs-based quality of life and self-perceived health inequity in patients with multimorbidity: investigating psychometric measurement properties of the MultiMorbidity Questionnaire (MMQ) using primarily Rasch models

Journal of Patient-Reported Outcomes, 2023
Background Multimorbidity is a burden for the individual and to the healthcare sector worldwide, leading to a rising number of intervention studies towards this patient group.

Factor validation and Rasch analysis of the individual recovery outcomes counter [PDF]

, 2017
Objective: The Individual Recovery Outcomes Counter is a 12-item personal recovery self assessment tool for adults with mental health problems. Although widely used across Scotland, limited research into its psychometric properties has been conducted. We

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Exploring the reliability, validity, and dimensionality of the ‘Kieler kindergarten test for mathematics’

Pedagogische Studiën, 2022
Mathematical literacy consists of several content areas. However, in kindergarten, most assessments focus solely on the number area. It is yet unknown whether the content areas of mathematical literacy can already be distinguished in young children. The
