Lean digital education to resolve the paradox of the illusion of digital prosperity

Journal of Innovation & Knowledge
Digital education, including digitally supported education, is loaded with biases. Most participants are blinded by the abundance of digital devices and misled by the hardware and software providers who try to convince and force education systems to keep

Combining multi-scale composite windows with hierarchical smoothing strategy for fingerprint orientation field computation

BioMedical Engineering OnLine, 2018
Background Orientation field (OF) plays a very significant role in automatic fingerprint recognition systems. Many algorithms have been proposed for the estimation of fingerprints’ OF but it is hard to solve the dilemma of correcting spurious ridge ...

De Rerum Natura: How Do Halide Perovskites Self‐Heal From Damage?

Advanced Materials, EarlyView.
How can lead‐halide‐perovskites self‐heal after damage from light, heat, mechanical strain, or radiation? We show that reversible chemical defects underly performance losses and recovery, highlighting the roles of halide and proton migration, redox‐driven reactions, and acid‐base equilibria.

Bioengineering concept of winemaking development to reduce the risks of age-related diseases [PDF]

E3S Web of Conferences
Scientists explain the anti-aging effect of red dry wines consumption primarily because of the presence of the biopolyphenolic compound resveratrol, which has pronounced antioxidant properties. There is experimental evidence that unfermented grape juice,

Chiral Metal Halide Perovskites for Spin‐Polarized Light‐Emitting Diodes

Advanced Materials, EarlyView.
Chiral metal–halide perovskites offer a route to circularly polarized light without external polarizers. This Perspective compares two spin‐light emitting diode concepts: intrinsically chiral emissive layers and chiral spin‐filter interlayers that inject spin‐polarized carriers into efficient achiral emitters.

From Copper Nanoparticles to Alumina Encapsulated Porous Layers With Enhanced Mechanical Stability

Advanced Materials Interfaces, EarlyView.
This study analyzes the synthesis‐structure relation of individual Cu nanoparticles and highly porous nanoparticle‐based Cu films using different sputtering‐based nanoparticle sources. The inherent mechanical instability of the films is tackled with Al2O3 encapsulation through atomic layer deposition, enabling 4‐fold increase in critical force in ...

Note on aligned Petrov type D purely magnetic perfect fluids

, 2006
We recently showed (Class. Quantum Grav.\ 23, 3353; gr-qc/0602091) that aligned Petrov type D purely magnetic perfect fluids are necessarily locally rotationally symmetric (LRS) and hence are all explicitly known. We provide here a more transparent proof.

Lattice Structures for Bone Replacement: The Intersection of Bone Biomechanics, Lattice Design, and Additive Manufacturing

Advanced Materials Technologies, EarlyView.
This review outlines how understanding bone's biology, hierarchical architecture, and mechanical anisotropy informs the design of lattice structures that replicate bone morphology and mechanical behavior. Additive manufacturing enables the fabrication of orthopedic implants that incorporate such structures using a range of engineering materials ...
