Automated robotic monitoring and inspection of steel structures and bridges [PDF]

Robotica (Cambridge. Print), 2017
Summary This paper presents visual and 3D structure inspection for steel structures and bridges using a developed climbing robot. The robot can move freely on a steel surface, carry sensors, collect data and then send to the ground station in real-time ...

Reconstructing enzyme evolution by protein engineering

FEBS 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 ...

Parametric study on concrete-filled steel tubular T-joints under in-plane bending

, 2018
Concrete filled steel tubular connections are being increasingly used in various engineering structures. Stress concentration usually exists at the vicinity of the welded joint.

Influence of stress states on cleavage fracture in X70 pipeline steels

Journal of Pipeline Science and Engineering, 2022
Stress state is a primary factor controlling the ductile fracture behavior of steels, which is typically represented as the combination of the stress triaxiality and Lode angle parameter.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Standardised material properties for numerical parametric studies of stainless steel structures and buckling curves for tubular columns

Journal of constructional steel research, 2019
While the nominal material properties given in material specifications are suitable for design purposes, for the generation of realistic numerical parametric results that are ‘equivalent’ to physical experiments, material properties that are ...

Temperature-dependent deformation and fracture properties of low-carbon martensitic steel in different stress states

Journal of Materials Research and Technology, 2023
The temperature-dependent ductile-brittle transition (DBT) in low-carbon martensitic steel is investigated in different stress states. To capture the effects of the stress state, tensile tests have been performed with flat specimens and three-point ...

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

Molecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Somatic mutational landscape in von Hippel–Lindau familial hemangioblastoma

Molecular Oncology, EarlyView.
The causes of central nervous system (CNS) hemangioblastoma in Von Hippel–Lindau (vHL) disease are unclear. We used Whole Exome Sequencing (WES) on familial hemangioblastoma to investigate events that underlie tumor development. Our findings suggest that VHL loss creates a permissive environment for tumor formation, while additional alterations ...

Static Analysis of Selected Types of Roof Trusses Considering the Weakening of the Structural Elements

Slovak Journal of Civil Engineering
Failures of structural elements in historical roof trusses pose a significant challenge in the preservation and restoration of a cultural heritage. These trusses, traditionally constructed from wood, are exposed to various factors that contribute to ...
