Compact Wavelength Selective Crossbar Switch with Cascaded First Order Micro-Ring Resonators
Photonics, 2022 We demonstrate a compact 4×4 wavelength selective switch with 50% fewer electrical signal pads as compared with our previous generation. We report loss and crosstalk for different paths of the switch.

What Drives Task Performance During Animal Fluency in People With Alzheimer’s Disease?
Frontiers in Psychology, 2020 BackgroundAnimal fluency is a widely used task to assess people with Alzheimer’s disease (AD) and other neurological disorders. The mechanisms that drive performance in this task are argued to rely on language and executive functions.

“Switched”: store‐switching behaviours [PDF]
International Journal of Retail & Distribution Management, 2008 PurposeThe purpose of this paper is to investigate store‐switching behaviours for main food‐shopping consequent on a change in operator for a major superstore; to relate results to previous research findings on store‐switching levels; and to use the results to emphasise new directions and dimensions for store‐switching research.Design/methodology ...

Ultra-fast hybrid systems for protecting direct current circuits with high magnetic energy [PDF]
Bulletin of the Polish Academy of Sciences: Technical Sciences, 2021 The article presents a new generation of ultra-fast hybrid switching systems (USH) for reliable, ultra-fast protection of various medium and low voltage DC systems (MVDC and LVDC). The DC switch-off takes place in a vacuum chamber (VC) cooperating with a
