Sonified Signals From a Compact FT‐ICR Instrument: A Feasibility Study. I—Data Mapping to an Equal‐Tempered Chromatic Scale

open access: yesRapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale Ions trapped within a Penning cell (ICR) travel periodic orbits whose frequencies are dependent on their mass‐to‐charge ratio and the value of the magnetic field passing through the trap. Fourier transformation (FT‐ICR) decomposes the signal induced in the detection circuit by the rotation of the ions in the cell after the ...

Inertial Energy Storage for Spacecraft [PDF]

open access: yes, 1984
The feasibility of inertial energy storage in a spacecraft power system is evaluated on the basis of a conceptual integrated design that encompasses a composite rotor, magnetic suspension and a permanent magnet (PM) motor/generator for a 3-kW orbital ...

Metal‐Free Submicron‐Hollow‐Fiber Conjugated Polymer Sponges for Efficient Pollutant Removal and Thermal Insulation

open access: yesSmall, EarlyView.
Mimicking natural tubular structures, metal‐free conjugated hollow fibers are synthesized via one‐pot Chichibabin condensation. Pyridinic networks spontaneously self‐assemble into submicron hollow fibers and entangle into spongy monoliths—without templates, metals, or post‐processing.

Enhancing durability of steam‐cured precast concrete culverts using SCMs: A comparative study with delithiated beta spodumene

open access: yesStructural Concrete, EarlyView.
Abstract Steam curing is commonly used to manufacture precast culverts to accelerate early strength development. This study investigates the effect of supplementary cementitious materials (SCMs) on the permeability properties of steam‐cured precast concrete culverts.

Types of Struggles in Disrupted Interaction: A Case of Hard‐of‐Hearing Employees

open access: yesSymbolic Interaction, EarlyView.
Everyone experiences disrupted interactions in their everyday life. However, research indicates that people with functional impairments are particularly exposed to patterns of interactional inequality at work. Despite this, little is known about the specific disrupted interactions in everyday life and the various types of interactional struggles this ...

Calculating the interior permanent-magnet motor [PDF]

open access: yes, 2003
This paper describes the calculation of torque in a brushless permanent-magnet line-start AC motor by means of the flux-MMF diagram in combination with the finite-element method.

AstroECP: towards more practical electron channeling contrast imaging

open access: yesJournal of Applied Crystallography, EarlyView.
We explore and address many of the major challenges associated with using electron channeling contrast imaging in a scanning electron microscope, with the goal of more easily revealing and characterizing crystalline defects such as dislocations.Electron channeling contrast imaging (ECCI) is a scanning electron microscope based technique which enables ...

Yoruba Histories of Marriage and Belonging: Gender, Power and Innovation in Eighteenth‐Century West Africa

open access: yesGender &History, EarlyView.
ABSTRACT This article argues that marriage was central to historical change in the Yoruba‐speaking region of West Africa during the eighteenth century. It draws on ìtàn, a distinct oral source, to show that conjugality shaped Yoruba processes of urbanisation and political centralisation, gendered divisions of labour and social innovation and creativity.

Warm Spring Weather Alters Calling Phenology of Four Sympatric Early‐Breeding Anurans

open access: yesIntegrative Zoology, EarlyView.
An unusually warm March in 2024 (“false spring”) followed by freezing temperatures allowed us to assess the impact of a weather event on an amphibian community. The calling activity of all four species was associated with increasing temperature, and the first date of calling was advanced by 11–18 days.
