A Weierstrass-Kenmotsu Type Representation for CMC $0\le H<1$ in \$\mathbb{H}^3(-1)$

Magdalena Toda, Erhan Guler, Madusha Dilhani Atampalage · 2026

We develop a complete Weierstrass-Kenmotsu type representation for conformal immersions of constant mean curvature $0\le H<1$ in the hyperbolic 3-space $\HH$. Our construction rests on three geometric…

Aesthetics of Robot-Mediated Applied Drama: A Case Study on REMind

Elaheh Sanoubari, Alicia Pan, Keith Rebello, Neil Fernandes, Andrew Houston, Kerstin Dautenhahn · 2026

Social robots are increasingly used in education, but most applications cast them as tutors offering explanation-based instruction. We explore an alternative: Robot-Mediated Applied Drama (RMAD), in w…

Mars excitement in Australian newspapers, 1877-1899: Humour and the public negotiation of astronomical knowledge

Richard de Grijs (Macquarie University, Sydney, Australia) · 2026

Speculation about Martian canals was a recurring feature of late nineteenth-century popular astronomy. This paper examines how colonial newspapers used humour to negotiate the epistemic uncertainty an…

A Dayem Loop Qubit Based on Interfering Superconducting Nanowires

Cliff Sun, Alexey Bezryadin · 2026

We propose a qubit design based on two parallel superconducting nanowires (i.e., a "Dayem loop qubit"). The inclusion of two nanowires instead of one leads to the Little-Parks effect, which provides a…
