Lattice Structure Design Method Aimed at Energy Absorption Performance Based on Bionic Design

open access: yesMachines, 2022
To obtain the lattice structure with excellent energy absorption performance, the structure of loofah inner fiber is studied to develop bionic design of lattice structure by experiment and simulation analysis method. From the compression experiment about

A study on damage evolution in Cu-TiO2 composite fabricated at different temperatures and strain rates

open access: yesMaterials Research Express, 2021
Copper/Titanium Dioxide (CuTiO _2 ) samples were fabricated at three temperatures (450 °C, 650 °C, 850 °C) using: a universal testing machine (quasi-statically at the strain rate of 8 × 10 ^–3 s ^−1 ), a drop Hammer (dynamically at the strain rate of ...

Baryon flow at SIS energies [PDF]

open access: yes, 1998
We calculate the baryon flow $$ in the energy range from .25 to $\le 2.5 AGeV$ in a relativistic transport model for $Ni+Ni$ and $Au+Au$ collisions employing various models for the baryon self energies.

Characterization of physical properties of tissue factor–containing microvesicles and a comparison of ultracentrifuge-based recovery procedures

open access: yesJournal of Extracellular Vesicles, 2014
Microvesicles were isolated from the conditioned media of 3 cell lines (MDA-MB-231, AsPC-1 and A375) by ultracentrifugation at a range of relative centrifugal forces, and the tissue factor (TF) protein and activity, microvesicle number, size distribution

Quantum read-out for cold atomic quantum simulators [PDF]

open access: yes, 2019
Quantum simulators allow to explore static and dynamical properties of otherwise intractable quantum many-body systems. In many instances, however, the read-out limits such quantum simulations.

A classification of scalar field potentials with cosmological scaling solutions [PDF]

open access: yes, 1998
An attractive method of obtaining an effective cosmological constant at the present epoch is through the potential energy of a scalar field. Considering models with a perfect fluid and a scalar field, we classify all potentials for which the scalar field

Experimental bearing capacity of eccentrically loaded foundation near a slope

open access: yesStudia Geotechnica et Mechanica, 2019
Based on the response of small-scale model square footing, the present paper shows the results of an experimental bearing capacity of eccentrically loaded square footing, near a slope sand bed. To reach this aim, a steel model square footing of (150 mm ×

Density regulation in strictly metric-free swarms [PDF]

open access: yes, 2014
There is now experimental evidence that nearest-neighbour interactions in flocks of birds are metric free, i.e. they have no characteristic interaction length scale.
