Shape-dependence of particle rotation in isotropic turbulence
, 2014 We consider the rotation of neutrally buoyant axisymmetric particles suspended in isotropic turbulence. Using laboratory experiments as well as numerical and analytical calculations, we explore how particle rotation depends upon particle shape.

Bedload transport in rivers, size matters but so does shape
Scientific Reports, 2021 Bedload transport modelling in rivers takes into account the size and density of pebbles to estimate particle mobility, but does not formally consider particle shape.

Shapes within shapes: how particles arrange inside a cavity
, 2018 We calculate the configurational entropy of hard particles confined in a cavity using Monte Carlo integration. Multiple combinations of particle and cavity shapes are considered.

Effects of particle shape on mechanical performance of sand with 3D printed soil analog
Yantu gongcheng xuebao, 2020 At particle scale, the morphological characteristics have a significant effect on the mechanical responses of sand. To analyze such effect, a modified 3D shape factor S ′ is introduced to quantify the particle shape.

Transforming mesoscale granular plasticity through particle shape
, 2018 When an amorphous material is strained beyond the point of yielding it enters a state of continual reconfiguration via dissipative, avalanche-like slip events that relieve built-up local stress.

Momentum distribution of a freely expanding Lieb-Liniger gas [PDF]
, 2009 We numerically study free expansion of a few Lieb-Liniger bosons, which are initially in the ground state of an infinitely deep hard-wall trap. Numerical calculation is carried out by employing a standard Fourier transform, as follows from the Fermi-Bose

Single particle crushing tests of coarse grained soil considering size and shape effects
Yantu gongcheng xuebaoParticle size and shape significantly influence the crushing behaviors of coarse grained soil. In this study, the particle scanning, particle shape analysis, and single particle compression tests on the gravel soils of high filling project of Baihetan ...

The demagnetization factor for randomly packed spheroidal particles
, 2019 We investigate if the demagnetization factor for a randomly packed powder of magnetic spheroidal particles depend on the shape of the spheroidal particles and what the internal variation in magnetization is within such a powder.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Children with acute lymphoblastic leukemia (ALL) are at risk of severe outcomes from SARS‐CoV‐2 (SCV2). In the post‐pandemic context, where most children have been infected with SCV2, there are limited data on whether vaccination remains beneficial in children with ALL.
