Endothelial Cells Angiogenesis in Sulfated Glycosaminoglycan (GAG) Hydrogels Enhanced by Bioactive Glass‐Released Ions

Advanced Functional Materials, EarlyView.
A mechanically tunable hydrogel composed of gelatin, chondroitin sulfate and laminin promotes angiogenesis in vitro without the supplement of growth factors. Endothelial cells morphogenesis was further enhanced by medium conditioned with bioactive glass 58S‐released ions (Ca and Si), thus offering a promising strategy to vascularize 3D tissue ...

Exciton Binding Energy Modulation in 2D Perovskites: A Phenomenological Keldysh Framework

Advanced Functional Materials, EarlyView.
The intrinsic screening effects are successfully decoupled from structural distortion by rigorously designing a series of 2D perovskites. This enabled us to demonstrate how the dielectric environment modulates the quasiparticle bandgap and exciton binding energy.

Robust and Reversible Thermofluorescence in Solvent‐Free Thermoplastic Polyurethane Composites

Advanced Functional Materials, EarlyView.
Thermofluorescent polymer composites with high‐contrast optical outputs are prepared by solvent‐free blending of indenoquinacridone dye into a thermoplastic polyurethane matrix. The temperature‐dependent fluorescence originates from aggregation–dissociation of the dye molecules, regulated by competing hydrogen bonds from the polymer matrix.

Criterion-Related Construct Validity

Psychometrika, 1989
Established results on latent variable models are applied to the study of the validity of a psychological test. When the test predicts a criterion by measuring a unidimensional latent construct, not only must the total score predict the criterion, but the joint distribution of criterion scores and item responses must exhibit a certain pattern.

Discriminatory Power - An Obsolete Validation Criterion?

SSRN Electronic Journal, 2008
In this paper we analyse two common measures of discriminatory power - the Accuracy Ratio and the Area Under the Receiver Operator Characteristic - in a probabilistic framework. Under the assumption of a random default event, we verify that the measures will be portfolio dependent as discovered by Hamerle et al.

Validity of running criterion

SPIE Proceedings, 2015
The validity of running criterion for vector and scalar fields is analyzed. It is shown that such criterion may be used for scalar fields of any kind. This criterion may be implemented for relatively simple vector fields like heterogeneously polarized beams with central symmetry of their parameters and it cannot use for vector field of general type ...

Criterion-Related Validity of a Clinical Simulation

Journal of Nursing Education, 1986
ABSTRACT This study explored the criterion-related validity of a clinical simulation by examining nurse practitioner's (NP) performance as measured by a chart audit and direct observation of care with performance on a clinical simulation.

Rapid onset: A valid panic disorder criterion?

Depression and Anxiety, 1997
This study examined the value of the DSM-IV time criterion for panic disorder (PD) requiring an abrupt onset to panic attacks (PAs) with a time to peak intensity (TTPI) of less than 10 min, and evaluated features distinguishing rapid onset (TTPI < 10) from prolonged onset (TTPI > 10) panickers.
