Mechanical and biological properties of enhanced porous scaffolds based on triply periodic minimal surfaces

open access: yesMaterials & Design, 2022
Triply periodic minimal surfaces (TPMS) - based porous structures have been universally adopted for mimicking the properties of bone scaffolds due to their interconnected geometries with smooth surfaces and controllable pores.

Impact-induced hardening in dense frictional suspensions [PDF]

open access: yesPhys. Rev. Fluids 6, 033301 (2021), 2020
We numerically study the impact-induced hardening in dense suspensions. We employ the lattice Boltzmann method and perform simulations of dense suspensions under impacts, which incorporate the contact between suspended particles with the free surface of the suspension.

Impact of constrained rewiring on network structure and node dynamics [PDF]

open access: yes, 2014
In this paper, we study an adaptive spatial network. We consider a susceptible-infected-susceptible (SIS) epidemic on the network, with a link or contact rewiring process constrained by spatial proximity.

A new high‐precision 40Ar/39Ar age for the Rochechouart impact structure: At least 5 Ma older than the Triassic–Jurassic boundary

open access: yes, 2017
The Rochechourt impact structure in south‐central France, with maximum diameter of 40–50 km, has previously been dated to within 1% uncertainty of the Triassic–Jurassic boundary, at which time ~30% of global genera became extinct.

Complex crater formation: Insights from combining observations of shock pressure distribution with numerical models at the West Clearwater Lake impact structure

open access: yes, 2017
Large impact structures have complex morphologies, with zones of structural uplift that can be expressed topographically as central peaks and/or peak rings internal to the crater rim.

Analysis of UV and EUV emission from impacts on the Sun after 2011 June 7 eruptive flare [PDF]

open access: yes, 2016
On 2011 June 7 debris from a large filament eruption fell back to the Sun causing bright ultraviolet (UV) and extreme ultraviolet (EUV) splashes across the surface. These impacts may give clues on the process of stellar accretion. The aim is to investigate how the impact emission is influenced by structures in the falling ejecta and at the solar ...

Terrestrial Laser Scanning to Detect Liana Impact on Forest Structure [PDF]

open access: yes, 2018
Tropical forests are currently experiencing large-scale structural changes, including an increase in liana abundance and biomass. Higher liana abundance results in reduced tree growth and increased tree mortality, possibly playing an important role in ...

Asset Structure Impact on Capital Structure of Capital Market-Listed Firms in Indonesia and Malaysia [PDF]

open access: yes, 2017
Debt was able to be used by firm as source of funds for investment-related activities,especially when the amount of retained earnings was not sufficient to cover the amountof investment needed.

Impact of Structures from the Protein Structure Initiative [PDF]

open access: yesStructure, 2007
The collective efforts of the Protein Structure Initiative (PSI) have so far produced over 2700 protein structures (http://kb.psi-structuralgenomics.org/KB/, Metrics Module). This is an impressive statistic, but what of interest have we learned from these structures and what might be the future impact of this knowledge?

Leveraging current insights on IL‐10‐producing dendritic cells for developing effective immunotherapeutic approaches

open access: yesFEBS Letters, EarlyView.
In vivo IL‐10 produced by tissue‐resident tolDC is involved in maintaining/inducing tolerance. Depending on the agent used for ex vivo tolDC generation, cells acquire common features but prime T cells towards anergy, FOXP3+ Tregs, or Tr1 cells according to the levels of IL‐10 produced. Ex vivo‐induced tolDC were administered to patients to re‐establish/
