Investigation of the laser fluence and wavelength dependence in surface‐assisted laser desorption/ionization mass spectrometry using gold nanoparticles

open access: yesRapid Communications in Mass Spectrometry, EarlyView.
Rationale Surface‐assisted laser desorption/ionization (SALDI) mass spectrometry (MS) builds on the use of nanostructured surfaces (e.g., coatings of colloidal nanoparticles) to promote analyte desorption and ionization. The SALDI process is believed to occur mainly through thermal processes, resulting from heating of the nanosubstrate upon absorption ...

Dam It, I’m Stranded: Evaluating Fish Stranding Downstream of Two Hydropeaking Dams in Northern Ontario

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Globally, there has been an increase in the development and use of hydropower to produce energy. Hydropeaking is an operating regime that is used to meet real‐time energy demands; however, daily fluctuations in flows may result in fish becoming stranded.

Rotatable Lens‐Based 3D Reconstruction Method for Monocular Vision Systems

open access: yesSmartBot, EarlyView.
Accurate 3D reconstruction in confined environments remains challenging because conventional vision‐based measurement systems are difficult to maintain compactness without sacrificing accuracy. Here, the authors develop a rotatable lens‐based monocular vision system, which is the first time using the refraction of the light induced by a rotating wedge ...

Polarization‐Dependent Elliptical and Rectangular Mie Voids

open access: yesSmall, EarlyView.
Polarization‐dependent Mie void resonances are realized by introducing anisotropic low‐index inclusions embedded in high‐index materials. Elliptical and rectangular void geometries enable controlled tuning of resonance behavior and optical mode formation.

The Trajectory of an Agreement: Tracing Objectivated Knowledge Across a Series of Mundane Encounters

open access: yesSymbolic Interaction, EarlyView.
This article adds to the sociological study of time and temporality in everyday life by building on recent longitudinal developments within conversation analysis. It investigates members' methods to bring about change within their shared (life) world. It examines how, as part of an extended project of action, one agreement made early on is continually ...

Diagnostic accuracy of ultrasound models for assessment of ovarian tumors: systematic review and meta‐analysis

open access: yesUltrasound in Obstetrics &Gynecology, EarlyView.
ABSTRACT Objective Accurate preoperative classification of ovarian tumors is essential for guiding treatment. There is an increasing body of data evaluating ultrasound‐based models for this purpose in diverse clinical settings. The aim of this systematic review and meta‐analysis was to generate up‐to‐date evidence on the diagnostic accuracy of the most
