Toward a unified theory of sparse dimensionality reduction in Euclidean space [PDF]

open access: yesSymposium on the Theory of Computing, 2013
Let $${\Phi\in\mathbb{R}^{m\times n}}$$Φ∈Rm×n be a sparse Johnson–Lindenstrauss transform (Kane and Nelson in J ACM 61(1):4, 2014) with s non-zeroes per column.

A characterization of light open maps of Euclidean spaces into Euclidean spaces [PDF]

open access: yesProceedings of the American Mathematical Society, 1958
We will use the term open map to mean a map f of X into Y such that f(U) is open in Y for every open set U in X. A map f of Rn (Euclidean n-space) into Rm is pseudo-monotone if and only if Rn_ -f(X) has no bounded component for every closed set X in Rn such that Rm -X has no bounded component.

Unsupervised non‐small cell lung cancer tumor segmentation using cycled generative adversarial network with similarity‐based discriminator

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Background Tumor segmentation is crucial for lung disease diagnosis and treatment. Most existing deep learning‐based automatic segmentation methods rely on manually annotated data for network training. Purpose This study aims to develop an unsupervised tumor segmentation network smic‐GAN by using a similarity‐driven generative adversarial ...

Quantum Dynamics on the three-dimensional q-deformed Euclidean Space [PDF]

open access: yesarXiv, 2020
I extend the three-dimensional q-deformed Euclidean space by a time element and discuss the algebraic structure of this quantum space together with its differential calculi. Using the star-product formalism, I will give basic operations of q-deformed analysis for the q-deformed Euclidean space with a time element.

Cwikel estimates revisited [PDF]

open access: yes, 2017
In this paper, we propose a new approach to Cwikel estimates both for the Euclidean space and for the noncommutative Euclidean space.

Subthalamic Nucleus Oscillatory Characteristics in Meige, Cervical Dystonia and Generalized Dystonia

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Deep brain stimulation offers a unique opportunity to record neural activity of the basal ganglia. While much work in dystonia has focused on the globus pallidus internus, expanding research to investigate subthalamic nucleus (STN) activity in various dystonia types is critical to provide a comprehensive understanding of dystonia ...

Realization of the Three-dimensional Quantum Euclidean Space by Differential Operators

open access: yes, 2000
The three-dimensional quantum Euclidean space is an example of a non-commutative space that is obtained from Euclidean space by $q$-deformation. Simultaneously, angular momentum is deformed to $so_q(3)$, it acts on the $q$-Euclidean space that becomes a $

On translation surfaces in 4-dimensional Euclidean space

open access: yes, 2016
We consider translation surfaces in Euclidean spaces. Firstly, we give some results of translation surfaces in the 3-dimensional Euclidean space E 3 . Further, we consider translation surfaces in the 4-dimensional Euclidean space E 4 .

Proper biconservative immersions into the Euclidean space [PDF]

open access: yes, 2013
In this paper, using the framework of equivariant differential geometry, we study proper $$\hbox {SO}(p+1) \times \hbox {SO}(q+1)$$SO(p+1)×SO(q+1)-invariant biconservative hypersurfaces into the Euclidean space $${\mathbb {R}}^n$$Rn ($$n=p+q+2$$n=p+q+2 ...
