External Prestressing Bridge Reinforcement Technology Review

open access: yesMATEC Web of Conferences, 2015
Externally prestressed bridge can not only limit and reduce the cracks and deformation of the structure, improve the rigidity and bearing capacity of structure, improve the stress state of structure, but also have less interference for bridge operation ...

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

open access: yesFEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Experimental studies of reinforced concrete structures of hydraulic structures strengthened with composite materials

open access: yesStructural Mechanics of Engineering Constructions and Buildings, 2019
Relevance. During the operation process (first of all, long-term operation) of hydraulic structures, it becomes necessary to strengthen their reinforced concrete structures.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Mechanical properties of tree roots for soil reinforcement models [PDF]

open access: yes, 2001
Evidence from forestry has shown that part of the forest floor bearing capacity is delivered by tree roots. The beneficial effect however varies and diminishes with increasing number of vehicle passes. Roots potential for reinforcing the soil is known to

Keratin 19 as a prognostic marker and contributing factor of metastasis and chemoresistance in high‐grade serous ovarian cancer

open access: yesMolecular Oncology, EarlyView.
Keratin 19 (KRT19) is overexpressed in high‐grade serous ovarian cancer with high levels of Kallikrein‐related peptidases (KLK) 4–7 and is associated with poor survival. In vivo analyses demonstrate that elevated KRT19 increases peritoneal tumour burden.

Suboptimal Choice Behaviour across Different Reinforcement Probabilities [PDF]

open access: yes, 2015
Six adult roosters’ choice behaviour was investigated across a series of five experimental conditions and a series of replication of the same five experimental conditions. Stagner and Zentall (2010) found that pigeons prefer to choose an alternative with

Seismic performance analysis of reinforced multi-story frames with external fractal dimension-buckling restrained braces

open access: yesJournal of Asian Architecture and Building Engineering
Leveraging fractal theory and the construction principle of diamond-shaped perforations for easy cutting, a regularly structured yet disorderly fractal dimension-buckling restrained brace (FD-BRB) core unit with diamond-shaped perforations was designed ...
