Catalan Bounds for Symmetric Strength‐Two Orthogonal Arrays

open access: yesJournal of Combinatorial Designs, EarlyView.
ABSTRACT A Hamming shell construction is a two‐level array obtained by taking every binary vector of a given Hamming weight a prescribed number of times, for each weight in turn. Such arrays are invariant under all permutations of the factors, and they are strength‐two orthogonal arrays exactly when the multiplicities satisfy three linear constraints ...

Post‐release tracking to monitor success of black cockatoo rehabilitation in Western Australia

open access: yesThe Journal of Wildlife Management, EarlyView.
Post‐release tracking of rehabilitated black cockatoos in Western Australia showed high success (79.4%), with survival, self‐feeding, and flock reintegration achieved by most birds. Larger resident flocks were significantly associated with improved post‐release outcomes.

Stark‐Tunable O‐Band Single‐Photon Sources Based on Deterministically Fabricated Quantum Dot ‐ Circular Bragg Gratings on Silicon

open access: yesLaser &Photonics Reviews, EarlyView.
Electrically contacted circular Bragg grating resonators incorporating InGaAs quantum dots directly grown on silicon enable bright, telecom O‐band single‐photon emission with wide‐range electrical tuning. A record quantum‐confined Stark shift of 16 nm is combined with high photon extraction efficiency, excellent single‐photon purity > 99.9%, and robust

On Gould–Hopper-Based Fully Degenerate Poly-Bernoulli Polynomials with a q-Parameter

open access: yesMathematics, 2019
We firstly consider the fully degenerate Gould⁻Hopper polynomials with a q parameter and investigate some of their properties including difference rule, inversion formula and addition formula.

Perspectives on Climate Change in Education for Sustainability: Linking Concepts and Skills for a Practical Ecological Transition

open access: yesSustainable Development, EarlyView.
ABSTRACT ‘Hard’ natural sciences have extensively been used to provide evidence that climate change is happening and climate action is needed. If the contribution of our economic activities to disturbing our climate systems is now largely accepted, the way in which we design and operationalise ‘climate action’—how we transition to more sustainable ...

Probabilistic degenerate logarithm and heterogeneous Stirling numbers

open access: yesKuwait Journal of Science
Let 𝑌 be a random variable whose moment-generating function exists in some neighborhood of the origin. While probabilistic Stirling numbers of the first and second kind have been introduced, early definitions often failed to satisfy fundamental ...

Living Through a Changing Climate: Stress, Trauma, and Gendered Resilience Among Women in Coastal and Northern Ghana

open access: yesSustainable Development, EarlyView.
ABSTRACT Climate change is reshaping everyday life in Ghana through coastal erosion, flooding, erratic rainfall, water scarcity, extreme heat, and agricultural insecurity. This study examines how these changes produce stress, trauma, and gendered resilience among women in Salakope and Choggu Yapalsi, two climate‐vulnerable communities in coastal and ...

Scalable Room‐Temperature Terahertz Graphene Cameras

open access: yesSmall Methods, EarlyView.
ABSTRACT Terahertz (THz) imaging has emerged as a powerful tool for non‐destructive, label‐free analysis across several scientific disciplines, ranging from materials science to biomedical research. By capturing the spatial‐dependent information in a broad range of frequencies, this technique enables the identification of chemical composition ...

Contemporary and Future Challenges for Structured Democratic Dialogue

open access: yesSystems Research and Behavioral Science, EarlyView.
ABSTRACT Structured Democratic Dialogue (SDD) is a participatory problem structuring methodology grounded in Structured Dialogic Design Science. It was created to help diverse stakeholders co‐construct influence maps that reveal leverage points and support coordinated action.

An Overview of High‐Temperature Superconducting Cables in DC Systems: Unlocking Potential for High‐Voltage DC Networks

open access: yesHigh Voltage, EarlyView.
ABSTRACT This paper provides an overview of high‐temperature superconducting (HTS) cables in DC systems, with a focus on their deployment in high‐voltage DC (HVDC) networks. The assessment of HTS cable properties—such as extremely low electrical resistance, high current‐carrying capacity and a compact geometry—and their comparison with those of ...
