Numerous studies have compared machine learning (ML) and discrete choice
models (DCMs) in predicting travel demand. However, these studies often lack
generalizability as they compare models deterministically without considering
contextual v...
On the relationship between orbital moment anisotropy,
magnetocrystalline anisotropy, and Dzyaloshinskii-Moriya interaction in
W/Co/Pt trilayers

We have studied the Co layer thickness dependences of magnetocrystalline
anisotropy (MCA), Dzyaloshinskii-Moriya interaction (DMI), and orbital moment
anisotropy (OMA) in W/Co/Pt trilayers, in order to clarify their correlations
with each o...

Numerical Analysis
A new representation of splines that targets efficiency in the analysis of
functional data is implemented. The efficiency is achieved through two novel
features: using the recently introduced orthonormal spline bases, the so-called
{\it spl...

The recent opening of gravitational wave astronomy has shifted the debate
about black hole mimickers from a purely theoretical arena to a
phenomenological one. In this respect, missing a definitive quantum gravity
theory, the possibility to...

Logic in Computer Science
We propose an interpretation of multiparty sessions with asynchronous
communication as Flow Event Structures. We introduce a new notion of global
type for asynchronous multiparty sessions, ensuring the expected properties for
sessions, incl...

Gross-Joyce-Tanaka arXiv:2005.05637 proposed a wall-crossing conjecture for
Calabi-Yau fourfolds. Assuming it, we prove the conjecture of Cao-Kool
