Split-Stirling-cycle displacer linear-electric drive [PDF]
, 1983 The retrofit of a 1/4-W split-Stirling cooler with a linear driven on the displacer was achieved and its performance characterized. The objective of this work was to demonstrate that a small linear motor could be designed to meet the existing envelope ...

Laser &Photonics Reviews, EarlyView.Manipulating the ultranarrow linewidth spectral features of quasi bound states in the continuum is challenging. A metasurface supporting linear‐to‐linear cross‐polarization coupling efficiency surpassing 25% is proposed to address the issue. Less than 100 nm linewidth is achieved, enabling the device to be applied to wavelength‐selective polarization ...

Evaluation of a second order simulation for Sterling engine design and optimisation
Journal of Energy in Southern Africa, 2017 This paper reports on the investigation of the simulation accuracy of a second order Stirling cycle simulation tool as developed by Urieli (2001) and improvements thereof against the known performance of the GPU-3 Stirling engine.

Tree planting, natural colonisation, hybrid approaches: Land manager decisions explored
People and Nature, EarlyView.Abstract There is a global drive to protect biodiversity and help combat climate change. In the UK, this is expressed in a number of policy initiatives and tools that include increasing tree cover as an important nature‐based solution to achieving national policy targets.

Space‐Efficient Logical Qubit Architecture with a Bus for Magic State Consumption
Advanced Quantum Technologies, EarlyView.This paper proposes a logical qubit architecture, considering the consumption of magic states. By constructing the patch to the magic state using the repetition code and data qubits using the surface code, the proposed architecture minimizes the number of qubits, referred to as the space cost.

Are boards reluctant to remove poorly performing successors to interim CEOs?
Strategic Management Journal, EarlyView.Abstract Research Summary Interim CEO appointments are disruptive and costly to firms. Boards justify them as necessary to find the right permanent successor. But what happens if that successor performs poorly? This paper argues that directors may be reluctant to remove a poorly performing successor to an interim CEO early in their tenure.

Small, EarlyView.A thermally robust, hierarchically porous polyimide aerogel is engineered via solvent‐polymer interaction tuning to enable stable laser‐induced graphitization. The resulting graphene‐integrated structure exhibits low resistivity, excellent dielectric performance, and thermal insulation, supporting applications in flexible electronics, thermal ...

Wildlife Biology, EarlyView.Many bird species are monitored using auditory point count surveys during the breeding season. Autonomous recording units (ARUs) can be used to better understand the daily and seasonal timing of when a species is vocalizing, which can help align surveys with the time period when the maximum number of individuals are present. We used ARUs to improve our
