Additive Manufacture of 3D Auxetic Structures by Laser Powder Bed Fusion—Design Influence on Manufacturing Accuracy and Mechanical Properties

Applied Sciences, 2020
The mechanical response of steel auxetic structures manufactured using laser-powder bed fusion was explored. The level of control exerted by the key design parameters of vertical strut length (H), re-entrant strut length (L), strut thickness (t) and re ...

In-plane and out-of-plane quasi-static compression performance enhancement of 3D printed re-entrant diamond auxetic metamaterial with geometrical tuning and fiber reinforcement

Defence Technology, 2023
Auxetic materials are cellular materials with a unique property of negative Poisson's ratio. The auxeticity and performance of these metamaterials utterly depend on the geometrical parameters and loading direction.

Re-entrant spin susceptibility of a superconducting grain

, 1999
We study the spin susceptibility chi of a small, isolated superconducting grain. Due to the interplay between parity effects and pairing correlations, the dependence of chi on temperature T is qualitatively different from the standard BCS result valid in

The newfound relationship between extrachromosomal DNAs and excised signal circles

FEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Scheduling of re-entrant flow shops [PDF]

Journal of Operations Management, 1983
AbstractWe propose and develop a scheduling system for a very special type of flow shop. This flow shop processes a variety of jobs that are identical from a processing point of view. All jobs have the same routing over the facilities of the shop and require the same amount of processing time at each facility.

Vibration attenuation using a 3D cubic re-entrant metamaterial structure with tunable bandgaps induced by variations in the re-entrant angle

EPJ Applied Metamaterials
This study explores the vibration attenuation capabilities of three-dimensional metamaterial periodic structures, leveraging the properties of auxetic structures and phononic crystals in forming bandgaps.

Dual atrioventricular nodal non-re-entrant tachycardia [PDF]

Europace, 2015
Dual atrioventricular nodal non-re-entrant tachycardia (DAVNNT), also known as 'double fire', has recently received more attention since it was demonstrated to mimic more common arrhythmias such as atrial premature beats, atrial fibrillation, and ventricular tachycardia.

The chiral Anomalous Hall effect in re-entrant AuFe alloys [PDF]

, 2006
The Hall effect has been studied in a series of AuFe samples in the re-entrant concentration range, as well as in part of the spin glass range. An anomalous Hall contribution linked to the tilting of the local spins can be identified, confirming ...

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

FEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Microwave Bandpass Filters Using Re-Entrant Resonators [PDF]

IEEE Transactions on Microwave Theory and Techniques, 2015
Design techniques for microwave bandpass filters using re-entrant resonators are presented. The key feature is that each re-entrant resonator in the filter generates a passband resonance and a finite frequency transmission zero, above the passband.
