Synchrotron Circular Polarization in Gamma-Ray Burst Prompt Optical Emission: Relativistic Thermal Electron Contribution

open access: yesThe Astrophysical Journal
Synchrotron circular polarization of a nonthermal power-law electron distribution in gamma-ray bursts (GRBs) has been studied. However, some numerical simulations have shown that the resulting distribution of electrons is a combination of a thermal ...

Law and the Circular Economy [PDF]

open access: yes, 2019
Assesses whether English law can accommodate the circular economy. Reviews key features of the circular economy, its status within organisations, and how it may be distinguished from the sharing economy. Considers whether regimes applicable to the treatment of waste may need reform to operate in circular economies, and how the personal property ...

Is an Apple an Orange? A Large Language Model Benchmark for Candidate Term Extraction and Subclass Decisions Against Upper Ontologies in Engineering and Materials Science

open access: yesAdvanced Engineering Materials, EarlyView.
Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.

Circular Priorities in Secured Transactions Law

open access: yesAlberta Law Review, 2010
Circular priority problems are endemic in secured transaction law. A circular priority situation arises when there are three or more parties with competing claims to the same asset and there is no clear ranking of priority among them. There are multiple approaches applied by courts or advanced by commentators to resolve circular priority problems.

Symbolic Regression and Multi‐Objective Optimization of the Flory–Huggins Interaction Parameter for Hydrogels

open access: yesAdvanced Engineering Materials, EarlyView.
We develop a data‐driven method to derive the mathematical expressions of the Flory–Huggins interaction parameter χ for the swelling behavior of temperature–responsive hydrogels. Starting from initial assumptions of χ, our workflow combines Bayesian optimization, Flory–Rehner theory, and symbolic regression to generate candidate χ expressions.

Treatment of unaccompanied minors in primary care clinics - caregivers' practice and knowledge

open access: yesIsrael Journal of Health Policy Research, 2018
Background By law, the provision of medical treatment to minors in the State of Israel is conditional upon the consent of their parents. In 2004, the Head of the Medical Administration Unit in the Ministry of Health issued Circular No.

Microstructure‐Controlled Crack Propagation and Fracture Resistance in MoSiBTiC Alloy Revealed by Multiscale Extended Finite Element Method Modeling

open access: yesAdvanced Engineering Materials, EarlyView.
A two‐dimensional multiscale finite element analysis framework was established for the first‐generation MoSiBTiC alloy, and the mechanical and fracture‐related parameters of the constituent phases were calibrated through experiments and simulations. The framework provides a basis for analyzing crack propagation behavior in its complex microstructure ...

Creep‐Induced Microstructural Evolution in an A2‐B2 Superalloy

open access: yesAdvanced Engineering Materials, EarlyView.
A 27.3Ta‐27.3Mo‐27.3Ti‐8Cr‐10Al (at.%) refractory high‐entropy alloy with precipitation‐strengthened A2‐B2 microstructure was studied by creep tests at 1030°C, which demonstrate a transition in deformation mechanisms in the range of 100–150 MPa applied stress. This is associated with changes in dislocation–precipitate interactions. Relevant deformation

Modular Critical Element Recycling Platform Using a Nanoporous Additively Manufactured Gyroid

open access: yesAdvanced Engineering Materials, EarlyView.
A modular recycling platform integrates 3D‐printed nanoporous gyroid structures to enable efficient critical element recovery. This system utilizes a hierarchical architecture, combining macroscopic channels with polymerization‐induced nanoscale porosity. By systematically tuning structural wall thickness and resin formulation, the platform achieves an

EU sales law and sustainable consumption of goods

open access: yesPrawne Problemy Górnictwa i Ochrony Środowiska
The article attempts to define a new approach in EU contract law to regulate the consumers sales contract in the view to protect environment, sustainability and the circular economy. One of the key aspects of ensuring sustainable consumption of goods is
