Hitless Rate Switching for Dynamically Reconfigurable Optical Systems

IEEE Photonics Journal, 2015
We propose a set of techniques to enable hitless rate switching for reconfigurable optical systems and validate, by computer simulations, their applicability to NRZ, RZ, and Nyquist pulse shapes. The polarization-multiplexed quadrature phase-shift keying

Affective dimensions in the information behavior of forcibly displaced people: A literature review. An Annual Review of Information Science and Technology (ARIST) paper

Journal of the Association for Information Science and Technology, EarlyView.
Abstract This review analyzed 241 scholarly articles published between 2010 and 2025 in information science venues to examine how affect shapes refugees' information behavior during forced migration and to identify additional contextual factors. It identifies seven affective dimensions: anxiety, shame and stigma, grief and loss, frustration, (mis)trust,

Frequency dissemination with free-space optical links

, 2010
Optical clock technology is very certain to be integrated in the next high precision time standards. The demand for higher accuracy in time synchronization makes the use of free-space optical links necessary for frequency dissemination, especially if ...

Form flows function: Learner‐centered game Re‐design in a STEM classroom

British Educational Research Journal, EarlyView.
Abstract Re‐designing games facilitates interest‐driven learning and immerses learners in systems thinking. However, there are limited studies exploring how the form and function of tabletop games influence learners' design decisions and learning experiences. To address this gap, we conducted a mixed‐methods study in a STEM classroom in western Canada.

Harnessing blood clot as a native scaffold for orchestrating tissue repairs and regeneration

BMEMat, EarlyView.
The blood clot, owing to its dynamic composition and unique microenvironment, holds significant yet underappreciated potential for tissue engineering. This review systematically summarizes the pathophysiology of clot formation, the key regulatory factors shaping its microenvironment, and its applications in both pre‐clinical and clinical settings ...

Formalising Sustainability Management as a Core Process Group in Project Management

Business Strategy and the Environment, EarlyView.
ABSTRACT Sustainability has become a strategic imperative for organisations, yet widely used project management standards such as the PMBoK sixth and seventh editions still do not formalise how sustainability should be embedded across project work. This gap matters because PMBoK‐based processes shape governance, roles, documentation and performance ...

Green-pumped, picosecond MgO:PPLN optical parametric oscillator

, 2011
We investigate the performance of a magnesium-oxide-doped periodically poled lithium niobate crystal (MgO:PPLN) in an optical parametric oscillator (OPO) synchronously-pumped by 530nm, 20ps, 230MHz pulses with an average power of up to 2W from a ...

A Critical Analysis of Microsoft's Rhetoric and Reality of Sustainability Engagement

Business Strategy and the Environment, EarlyView.
ABSTRACT This study critically examines Microsoft's environmental, social and governance (ESG) rhetoric and operational reality, to offer insights that extend beyond conventional greenwashing or bluewashing. Drawing on over 20 years of Microsoft's sustainability reports (2003–2024), third‐party ESG evaluations and media investigations, it employs ...
