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 Nematic Phase Established for Several Homologous Biaromatic Liquid Crystals by Investigation of Binary Mixed Systems [PDF]

, 1981
Several homologous series of biaromatic liquid crystals with structure type CnH2n+1O • C6H4 • M•C6H4-CN are investigated. By studying the phase transition temperatures in binary mixed systems a "re-entrant" nematic phase N(re) is established for all ...

Mechanisms of parasite‐mediated disruption of brain vessels

FEBS Letters, EarlyView.
Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

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.

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 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 ...

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 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 ...

Workload control in job shops with re-entrant flows:an assessment by simulation [PDF]

, 2016
One of the key functions of Workload Control is order release. Jobs are not released immediately onto the shop floor – they are withheld and selectively released to create a mix of jobs that keeps work-in-process within limits and meet due dates.
