Advanced Functional Materials, EarlyView.A printed superparamagnetic nanoparticle‐based flux guide enables the realization of a hysteresis‐free three‐axis magnetic sensor. This innovative architecture efficiently redirects out‐of‐plane fields to planar sensing elements, facilitating simultaneous vector detection without complex reset protocols.

X-ray absorption tomography employing a conical shell beam [PDF]
, 2016 We demonstrate depth-resolved absorption imaging by scanning an object through a conical shell of X-rays. We measure ring shaped projections and apply tomosynthesis to extract optical sections at different axial focal plane positions.

Positive mass theorem for asymptotically flat spin manifolds with isolated conical singularities
, 2023 There has been a lot of interests in Positive Mass Theorems for singular metrics on smooth manifolds. We prove a positive mass theorem for asymptotically flat (AF) spin manifolds with isolated conical singularities or more generally horn singularities ...

Distribution of Flow Velocity Around Conical Nets [PDF]
, 1996 This paper deals with the velocity around the conical net in the flume tank at the Faculty of Fisheries, Kagoshima University. Eight types of conical nets were used for the experiment ; out of which four kinds were the same netting with different hanging
