The Accurate Method for Computing the Minimum Distance between a Point and an Elliptical Torus
Computers, 2016 We present an accurate method to compute the minimum distance between a point and an elliptical torus, which is called the orthogonal projection problem.

Some results about g-frames in Hilbert spaces [PDF]
MATEC Web of Conferences, 2022 The concept of g-frame is a natural extension of the frame. This article mainly discusses the relationship between some special bounded linear operators and g-frames, and characterizes the properties of g-frames.

Orthogonal Subspace Projection Target Detector for Hyperspectral Anomaly Detection
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021 Orthogonal subspace projection (OSP) is a versatile hyperspectral imaging technique which has shown great potential in dimensionality reduction, target detection, spectral unmixing, etc. However, due to its inherent requirement of prior target knowledge,

Orthogonal projection regularization operators [PDF]
Numerical Algorithms, 2007 The authors propose Tikhonov regularization operators of the form \(L = I - W W^T\), with \(W^T W = I\) and easy to be computed. They successfully apply these constructions to iterative and singular value decomposition-based methods. Numerical examples are presented for first kind integral equations and image restoration problems.

Orthogonal projections of hypercubes
Physical Review EProjections of hypercubes have been applied to visualize high-dimensional binary state spaces in various scientific fields. Conventional methods for projecting hypercubes, however, face practical difficulties. Manual methods require nontrivial adjustments of the projection basis, while optimization-based algorithms limit the interpretability and ...

Orthogonal Projections Based on Hyperbolic and Spherical n-Simplex
Advances in Mathematical Physics, 2015 Orthogonal projection along a geodesic to the chosen k-plane is introduced using edge and Gram matrix of an n-simplex in hyperbolic or spherical n-space. The distance from a point to k-plane is obtained by the orthogonal projection.

Orthogonal Neighborhood Preserving Projections [PDF]
Fifth IEEE International Conference on Data Mining (ICDM'05), 2006 Orthogonal neighborhood preserving projections (ONPP) is a linear dimensionality reduction technique which attempts to preserve both the intrinsic neighborhood geometry of the data samples and the global geometry. The proposed technique constructs a weighted data graph where the weights are constructed in a data-driven fashion, similarly to locally ...

An epithelial GPR35 isoform supports tumor‐associated transcriptional and metabolic phenotypes
FEBS Letters, EarlyView.GPR35 generates two functionally distinct isoforms with previously unresolved roles. GPR35‐short mediates immune‐cell chemotaxis, while GPR35‐long is enriched in colorectal cancer epithelium, where it supports increased metabolism, proliferation, and tumor‐associated transcriptional programs.
