Elastic‐Wave Propagation in Chiral Metamaterials: A Couple‐Stress Theory Perspective

open access: yesAdvanced Engineering Materials, EarlyView.
The intrinsic chirality of chiral metamaterials renders an effective medium based on the classical continuum theory ineffective for predicting their acoustic activity. This limitation is addressed in the present study by employing augmented asymptotic homogenization to derive a couple‐stress‐based effective medium, enabling accurate predictions in the ...

Torsion of the Hydatids of Morgagni: A Case Report

open access: yesThai Journal of Obstetrics and Gynaecology, 2009
Hydatids of Morgagni are pedunculated cysts situated close to the fimbriated end of the fallopian tube. They are usually incidental findings and rarely cause clinically significant.

Analytic torsion for graphs [PDF]

open access: yesarXiv, 2022
Analytic torsion is a functional on graphs which only needs linear algebra to be defined. In the continuum it corresponds to the Ray-Singer analytic torsion. We have formulas for analytic torsion if the graph is contractible or if it is a discrete sphere. A key insight is that analytic torsion is the super determinant of the Dirac operator of the graph.

Torsion of a splenule [PDF]

open access: yesPediatric Radiology, 2010
A 14-year-old boy presented with nausea and left-sidedabdominal pain of 2 days’ duration and had elevated whiteblood cells. Abdominal CT with contrast agent shows a 4×4×3.7-cm well-defined, hypodense structure in the splenichilumwithsurroundingfatstrandingandfreefluid(Fig.1). Itwas not a simple cyst and did not show significantenhancement. Differential

The trivial role of torsion in projective invariant theories of gravity with non-minimally coupled matter fields

open access: yes, 2017
We study a large family of metric-affine theories with a projective symmetry, including non-minimally coupled matter fields which respect this invariance.

Functional Recycling and Reuse of Nd–Fe–B Permanent Magnets from Various Waste Streams for a more Sustainable and Resilient Electromobility

open access: yesAdvanced Engineering Materials, EarlyView.
Due to the increasing demand and growing importance of resilient and sustainable supply chains, the use of recycled and reused Nd–Fe–B magnets in e‐mobility applications such as Pedelecs, e‐Scooters, and Hoverboards is being investigated. It can be shown that the corresponding motors with recycled magnets do not exhibit any loss of performance while at

Design and Evaluation of 3D‐Printed Polylactic Acid Composites Reinforced with Biodegradable Bamboo Powder and Jute Powder

open access: yesAdvanced Engineering Materials, EarlyView.
The study investigates 3D‐printed polylactic acid (PLA) composites with biodegradable bamboo and jute powder fillers. Mechanical, thermal, structural properties, and rheological behavior are discussed to evaluate composite performance. Morphological characterization indicates uniform dispersion and adhesion of the fillers in the PLA matrix with the ...
