Determination of Rail Vertical Profile through Inertial Methods

open access: yesProceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, 2010
Undergrounds and other metropolitan railway systems are characterized by their intense traffic, lasting up to 20 h per day, and so they need their maintenance work programmes to be optimized, implying an optimization of the monitoring processes. This article proposes an alternative to the traditional optical methods for monitoring rail profiles which ...

Holographic Mapping of Orbital Angular Momentum using a Terahertz Diffractive Optical Neural Network

open access: yesAdvanced Intelligent Discovery, EarlyView.
A compact six‐layer diffractive optical neural network enables direct recognition and spatial mapping of terahertz (THz) orbital angular momentum (OAM) beams. Fabricated by 3D printing, the system distinguishes nine OAM modes and their superpositions with high fidelity, good efficiency, and low crosstalk, offering a scalable solution for THz ...

Prediction‐Guided Two‐Step Solid‐State Exploration of Unknown Pseudo‐Ternary Oxides

open access: yesAdvanced Intelligent Discovery, EarlyView.
Prediction‐guided selection combined with two‐step solid‐state exploration enables efficient search of unknown pseudo‐ternary oxides. Broad robotic slurry screening followed by manual single‐phase isolation leads to the discovery of a new oxide, Ba5SnV6O22, showing how data‐guided experiments connect unexplored composition regions to new materials ...

Stakeholder Perspectives on Therapeutic and Safe Building Design in Residential Care

open access: yesAustralian Journal of Social Issues, EarlyView.
ABSTRACT Residential care is a form of out‐of‐home care that plays a critical role in supporting vulnerable young people in Australia. However, there is an evidence gap regarding the built environment in this context. This research aimed to explore the perspectives of key stakeholders in residential care in Victoria, Australia, regarding design that ...

Circular Economy Pathways for Airport Climate Change Mitigation

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Airport operators face growing climate‐change pressures; the circular economy offers pathways to reduce impacts and recover resources. We examine how airport operators apply the circular economy in practice. We use an exploratory qualitative multicase design based on practitioner‐generated documents (e.g., press releases and sustainability ...

The Renal Activity Index for Lupus Identifies Active Renal Disease and Treatment Response in Adult Patients With Systemic Lupus Erythematosus and Lupus Nephritis. [PDF]

open access: yesArthritis Care Res (Hoboken)
Objective We evaluated the ability of the Renal Activity Index for Lupus (RAIL) to discriminate active lupus nephritis (LN) in adult patients with active systemic lupus erythematosus (SLE) and differentiate LN treatment response. Methods Urine samples from adults with biopsy‐proven active class III and IV LN from TULIP‐LN (active LN group ...

Investigation of the Phase‐Separation Point During CO2 Absorption in the DETA–Sulfolane–Water System

open access: yesCarbon and Hydrogen, EarlyView.
Optical scattering diagnostics combined with generalized solubility product modeling enables quantitative prediction of phase separation in DETA–sulfolane–water biphasic CO2 absorbents. ABSTRACT The phase‐separation behavior of liquid–liquid biphasic amine absorbents is typically identified using bubbling reactors, where visual observation is employed ...
