Effect of structure design on compressive properties and energy absorption behavior of ordered porous aluminum prepared by rapid casting

open access: yesMaterials & Design, 2019
In this study, ordered porous aluminum specimens with four different cubic structures, i.e. basic truss structure, high density truss structure, strengthened truss structure and graded truss structure, were fabricated by rapid casting combining the ...

Pioglitazone plus (−)‐epigallocatechin gallate: a novel approach to enhance osteogenic performance in aged bone marrow mesenchymal stem cells

open access: yesFEBS Open Bio, EarlyView.
Aged human bmMSCs are seeded in the scaffold. Osteoblastic induction can slightly increase cell's bone‐forming activity to produce bone‐like tissues, shown as the sporadic xylenol orange‐stained spots (the lower left image). Notably, pioglitazone plus EGCG co‐treatment dramatically increases cell's bone‐forming activity and bone‐like tissue production (

Modelling and analysis of system robustness for mechanical product based on axiomatic design and fuzzy clustering algorithm

open access: yesAdvances in Mechanical Engineering, 2015
Robust performance is the most important concern in the design of any product, especially in system design stage that precedes parameter design, because it actually determines the attainable level of product robustness in the parameter design phase.

Research progress of high temperature microwave-absorbing ceramic matrix composites

open access: yesJournal of Aeronautical Materials, 2019
Microwave-absorbing ceramic matrix composites play an important role in the development of heat-resisting stealthy materials due to their excellent high-temperature mechanical property, superior corrosion resistance and oxidation resistance.

Regression-aware decompositions

open access: yes, 2018
Linear least-squares regression with a "design" matrix A approximates a given matrix B via minimization of the spectral- or Frobenius-norm discrepancy ||AX-B|| over every conformingly sized matrix X.

Structure theorem of square complex orthogonal design [PDF]

open access: yes, 2013
Square COD (complex orthogonal design) with size $[n, n, k]$ is an $n \times n$ matrix $\mathcal{O}_z$, where each entry is a complex linear combination of $z_i$ and their conjugations $z_i^*$, $i=1,\ldots, k$, such that $\mathcal{O}_z^H \mathcal{O}_z = (

Enzymatic degradation of biopolymers in amorphous and molten states: mechanisms and applications

open access: yesFEBS Open Bio, EarlyView.
This review explains how polymer morphology and thermal state shape enzymatic degradation pathways, comparing amorphous and molten biopolymer structures. By integrating structure–reactivity principles with insights from thermodynamics and enzyme engineering, it highlights mechanisms that enable efficient polymer breakdown.

Design and Simulation Analysis of Micro-Porous Structure in Infiltration-Type Self-Lubrication Composites Matrix

open access: yesMATEC Web of Conferences, 2018
Metal ceramic preforms were fabricated by vacuum sintering method in this work. Ti–Fe–Cr–W–Mo–V powder was used as the basic material, TiH2 and CaCO3 were used as the composite pore-forming material and Al2O3 was used as dispersal particles.

Integrating Process and Work Breakdown Structure with Design Structure Matrix

open access: yesJournal of Advanced Computational Intelligence and Intelligent Informatics, 2010
In software development, project plans document scope, cost, effort, and schedule, guide project managers, and control project execution. Developing a project plan without incorporating how an organization doing things - i.e., organizational culture - may lead to project failure.

The role of lipid metabolism in neuronal senescence

open access: yesFEBS Open Bio, EarlyView.
Disrupted lipid metabolism, through alterations in lipid species or lipid droplet accumulation, can drive neuronal senescence. However, lipid dyshomeostasis can also occur alongside neuronal senescence, further amplifying tissue damage. Delineating how lipid‐induced senescence emerges in neurons and glial cells, and how it contributes to ageing and ...
