An Introduction To The Web-Based Formalism [PDF]

, 2016
This paper summarizes our rather lengthy paper, "Algebra of the Infrared: String Field Theoretic Structures in Massive ${\cal N}=(2,2)$ Field Theory In Two Dimensions," and is meant to be an informal, yet detailed, introduction and summary of that larger

Synchronous processing of orthogonal cyclic AFM signals under conditions of reception gain coefficient uncertainty

Технологія та конструювання в електронній апаратурі
A method has been proposed for synchronizing modems that use a system of cyclic amplitude-phase keyed signals encoded by multi-level numerical sequences with an ideal periodic autocorrelation function to transmit information.

Long Lead ENSO Forecast Using an Adaptive Graph Convolutional Recurrent Neural Network

Engineering Proceedings, 2023
El Niño-Southern Oscillation (ENSO), a natural phenomenon in the Pacific Ocean, is caused by cyclic changes in sea-surface temperature (SST) and the overlying atmosphere in the tropical Pacific.

A search for concentric rings with unusual variance in the 7-year WMAP temperature maps using a fast convolution approach [PDF]

, 2013
We present a method for the computation of the variance of cosmic microwave background (CMB) temperature maps on azimuthally symmetric patches using a fast convolution approach.

Common hypercyclic vectors for families of operators [PDF]

, 2008
We provide a criterion for the existence of a residual set of common hypercyclic vectors for an uncountable family of hypercyclic operators which is based on a previous one given by Costakis and Sambarino.

Swin transformer-based GAN for multi-modal medical image translation

Frontiers in Oncology, 2022
Medical image-to-image translation is considered a new direction with many potential applications in the medical field. The medical image-to-image translation is dominated by two models, including supervised Pix2Pix and unsupervised cyclic-consistency ...

Stiffness Analysis and Verification of Hydraulic Supporting Units for In-Situ Optical Testing of a 500 mm-Diameter Mirror

Machines, 2022
A hydraulic in-situ support system is commonly used in the optical testing of mirrors, since it is convenient to unload the gravity of a mirror to be measured without the risk of being turned over or moved to another place.

Composite Cyclotomic Fourier Transforms with Reduced Complexities

, 2010
Discrete Fourier transforms~(DFTs) over finite fields have widespread applications in digital communication and storage systems. Hence, reducing the computational complexities of DFTs is of great significance.

Observational constraints on the types of cosmic strings [PDF]

, 2014
This paper is aimed at setting observational limits to the number of cosmic strings (Nambu-Goto, Abelian-Higgs, semilocal) and other topological defects (textures).
