3D MHD analysis of prototypical manifold for liquid metal blankets
Nuclear Fusion, 2023 The water-cooled lead lithium (WCLL) and the dual-cooled lead lithium (DCLL) are two of the breeding blanket (BB) concepts that the EUROfusion consortium is pursuing in the framework of the development of the fusion reactor industrial demonstrator DEMO ...

Manifold Learning via Manifold Deflation
CoRR, 2020 Nonlinear dimensionality reduction methods provide a valuable means to visualize and interpret high-dimensional data. However, many popular methods can fail dramatically, even on simple two-dimensional manifolds, due to problems such as vulnerability to noise, repeated eigendirections, holes in convex bodies, and boundary bias.

Dimensionality Reduction Algorithms in Machine Learning: A Theoretical and Experimental Comparison
Engineering Proceedings, 2023 The goal of Feature Extraction Algorithms (FEAs) is to combat the dimensionality curse, which renders machine learning algorithms ineffective. The most representative FEAs are investigated conceptually and experimentally in our work.

Journal of Physics A: Mathematical and Theoretical, 2012 This article propounds, in the wake of influential work of Fefferman and Graham about Poincaré extensions of conformal structures, a definition of a (Poincaré-)Schrödinger manifold whose boundary is endowed with a conformal Bargmann structure above a non-relativistic Newton-Cartan spacetime.

Media Theory, 2021 This paper investigates how the current domestic application of the Internet of Things (IoT), called “smart home,” changes the socio-phenomenological meaning of place-making. It describes a smart home as a topological continuum that could unfold lots of

Base Manifolds for Lagrangian Fibrations on Hyperkähler Manifolds [PDF]
International Mathematics Research Notices, 2013 We show that the base manifold of a Lagrangian fibration on a hyperkähler manifold is isomorphic to complex projective space. This generalises a theorem of J.-M. Hwang to the Kähler case.

A Comparative Study of the Transmission from Plurality to Oneness in Plato and MullaSadra's Ontology [PDF]
حکمت معاصر, 2014 Plato on the basis of his unifier viewpoint offered the theory of Idea and other cosmological related to creation and the chain and arrangement of beings. He also placed the principal of Goodness in the climax of the pyramid of his ontology, and by which

Informational Approaches Lead to Formulations of Quantum Mechanics on Poincaré Disks
Proceedings, 2022 A novel methodological approach requires the observer to investigate the information accessible outside the object under scrutiny. The object becomes an “hole” devoid of information, surrounded by a container that is no longer a passive structure. We use

A Battlefield Target Grouping Method Based on M-CFSFDP Algorithm [PDF]
Xibei Gongye Daxue Xuebao, 2018 Target grouping can divide battlefield targets into battle space groups. In this way, the target grouping reduces the difficulty of situation assessment and increases the efficiency of decision.

IEEE Access, 2020 Since the cost of labeling data is getting higher and higher, we hope to make full use of the large amount of unlabeled data and improve image classification effect through adding some unlabeled samples for training.
