Shaped electrodes for adaptive X‐ray optics

Journal of Synchrotron Radiation, EarlyView.
For adaptive X‐ray optics on high‐performance beamline optical systems, we describe an approach to mirror figure and slope control using patterned, shaped electrodes to control the local curvature on a lithium niobate substrate from a single applied voltage. Longitudinally continuous electrode patterns achieve target shapes without discontinuities, and

Twisted accretion curtains in the intermediate polar FO Aquarii

, 2003
We report on a ~37-ks XMM-Newton observation of the intermediate polar FO Aquarii, presenting X-ray and UV data from the EPIC and OM cameras. We find that the system has changed from its previously reported state of disc-overflow accretion to one of ...

The prevalence of cannabidiol (CBD) use in North America and Europe: A meta‐analysis

Addiction, EarlyView.
Abstract Background and aims The global cannabidiol (CBD) market has expanded in recent years. Several studies suggest CBD use, whether for medical or recreational purposes, is on the rise; however, no systematic assessments of its prevalence have been conducted so far. This meta‐analysis aimed to estimate the prevalence of CBD use in North America and

Safety pharmacology of acute mescaline administration in healthy participants

British Journal of Clinical Pharmacology, EarlyView.
Aims Psychedelics, including mescaline, may serve as novel treatments for depression and anxiety. However, data is scarce on the safety of mescaline. Methods The present pooled analysis included two double‐blind, randomized, placebo‐controlled studies with a total of 48 participants and 96 mescaline administrations. Single oral‐dose administrations (n =

Artificial intelligence and machine learning techniques for power quality event classification: a focused review and future insights

Results in Engineering
Power Quality (PQ) disturbances are critical in modern power systems, significantly impacting electrical networks' stability, reliability, and efficiency. With the increasing penetration of renewable energy sources, non-linear loads, and power electronic

Characterization of phenanthrenequinone-doped poly(methyl methacrylate) for holographic memory [PDF]

, 1998
The holographic recording characteristics of phenanthrenequinone- (PQ-) doped poly(methyl methacrylate) are investigated. The exposure sensitivity is characterized for single-hologram recording, and the M/# is measured for samples as thick as 3 mm ...

Residual permutation tests for feature importance in machine learning

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Psychological research has traditionally relied on linear models to test scientific hypotheses. However, the emergence of machine learning (ML) algorithms has opened new opportunities for exploring variable relationships beyond linear constraints.

Cross‐Ownership and Welfare‐Inferior Price Competition with Relative Profit Delegation Contracts

Bulletin of Economic Research, EarlyView.
ABSTRACT We consider management reward contracts based on relative profit performance under cross‐ownership and find nonequivalence of price and quantity competition. We also examine an endogenous choice of competition mode under unilateral cross‐ownership and show that the welfare‐inferior price competition can appear unless the product's ...

Self‐supervised Learning of Fine‐to‐Coarse Cuboid Shape Abstraction

Computer Graphics Forum, EarlyView.
Abstract The abstraction of 3D objects with simple geometric primitives like cuboids allows us to infer structural information from complex geometry. It is important for 3D shape understanding, structural analysis and geometric modeling. We introduce a novel fine‐to‐coarse self‐supervised learning approach to abstract collections of 3D shapes.
