A Novel NeighShrink Correction Algorithm in Image Denoising

Iranian Journal of Electrical and Electronic Engineering, 2017
Image denoising as a pre-processing stage is a used to preserve details, edges and global contrast without blurring the corrupted image. Among state-of-the-art algorithms, block shrinkage denoising is an effective and compatible method to suppress ...

Free C+ actions on affine threefolds [PDF]

, 2005
We study algebraic actions of the additive group C+ on an affine threefold X and prove a smoothness property for the quotient morphism X -< X//C+. Then, following Shulim Kaliman, we give a proof of the conjecture that every free C+ action on affine 3 ...

IN THIS ISSUE: Food Systems Resilience

Journal of Agriculture, Food Systems, and Community Development, 2017
In this combined spring and summer issue of JAFSCD we highlight the growing interest in food systems resilience, as depicted on our cover by the design of the Hyperions project by Vincent Callebaut Architectures.

Stein transport for Bayesian inference [PDF]

We introduce $\textit{Stein transport}$, a novel methodology for Bayesian inference designed to efficiently push an ensemble of particles along a predefined curve of tempered probability distributions.

STEIN (SupraThermal Electrons, Ions and Neutrals), A New Particle Detection Instrument for Space Weather Research with CubeSats [PDF]

, 2009
The Space Sciences Laboratory at UC Berkeley is proposing a 3U CubeSat mission, the CubeSat for Ions, Neutrals, Electrons, and MAgnetic fields (CINEMA), to be funded by the NSF Space Weather CubeSat program and Kyung Hee University, S. Korea. CINEMA will

Playfulness an (Un)-performability in Gertrude Stein's Modernist Drama

Sinais de Cena, 2018
Gertrude Stein's theatre, a theatre of modernism, can be studied as an example of experimental dramaturgy, in that it finds itself suspended between two identities: that of discourse, and that of a theatrical score.

Latent Prototype-Based Clustering: A Novel Exploratory Electroencephalography Analysis Approach

Sensors
Electroencephalography (EEG)-based applications in brain–computer interfaces (BCIs), neurological disease diagnosis, rehabilitation, etc., rely on supervised approaches such as classification that requires given labels.

The Littlewood-Paley-Stein inequality for Dirichlet space tamed by distributional curvature lower bounds [PDF]

The notion of tamed Dirichlet space by distributional lower Ricci curvature bounds was proposed by Erbar, Rigoni, Sturm and Tamanini as the Dirichlet space having a weak form of Bakry-\'Emery curvature lower bounds in distribution sense.

Comparative Study on Photosynthetic Characteristics and Leaf Structure of Paphiopedilum parishii in Different Growth Periods

Agronomy
This study investigates the differences in photosynthetic characteristics of Paphiopedilum parishii (Rchb.f.) Stein during its reproductive and nutrient growth periods. Using plants from the same individual, we compared light response curves, chlorophyll
