Analysis of Deformation and Stress Characteristics of Anchored-Frame Structures for Slope Stabilization

open access: yesAdvances in Civil Engineering, 2020
In recent years, anchored-frame structures are widely being used in road slopes for stabilization and improvement. The technology of frame structure with anchors is becoming more and more mature, but the pertinent theory lags behind the application ...

Water Quality Carbon Nanotube-Based Sensors Technological Barriers and Late Research Trends: A Bibliometric Analysis

open access: yesChemosensors, 2022
Water is the key element that defines and individualizes our planet. Relative to body weight, water represents 70% or more for the majority of all species on Earth. Taking care of water as a whole is equivalent with taking care of the entire biodiversity

Element sets for high-order Poincar\'e mapping of perturbed Keplerian motion [PDF]

open access: yes, 2018
The propagation and Poincar\'e mapping of perturbed Keplerian motion is a key topic in celestial mechanics and astrodynamics, e.g. to study the stability of orbits or design bounded relative trajectories. The high-order transfer map (HOTM) method enables

Dropping cold quantum gases on Earth over long times and large distances [PDF]

open access: yes, 2006
We describe the non-relativistic time evolution of an ultra-cold degenerate quantum gas (bosons/fermions) falling in Earth's gravity during long times (10 sec) and over large distances (100 m).

Magnetization reversals in core–shell sphere clusters: finite-element micromagnetic simulation and machine learning analysis

open access: yesScientific Reports, 2023
Recently developed permanent magnets, featuring specially engineered microstructures of inhomogeneous magnetic phases, are being considered as cost-effective alternatives to homogeneous single-main-phase hard magnets composed of Nd2Fe14B, without ...

Does the universe in fact contain almost no information? [PDF]

open access: yes, 1996
At first sight, an accurate description of the state of the universe appears to require a mind-bogglingly large and perhaps even infinite amount of information, even if we restrict our attention to a small subsystem such as a rabbit. In this paper, it is

Size and Composition of the MORB+OIB Mantle Reservoir

open access: yesGeochemistry, Geophysics, Geosystems, 2022
Most efforts to characterize the size and composition of the mantle that complements the continental crust have assumed that the mid‐ocean ridge basalt (MORB) source is the incompatible‐element depleted residue of continental crust extraction. The use of
