An Effective DNA‐Based File Storage System for Practical Archiving and Retrieval of Medical MRI Data

Small Methods, Volume 8, Issue 10, October 18, 2024.
DNA‐based data storage is a revolutionary technology that allows for long‐term, high‐density data archiving. This work suggests an EDS system for archiving medical MRI data. The study's results and codes offer exciting prospects for the future of medical data storage and retrieval.

Fountain Codes with Nonuniform Selection Distributions through Feedback

, 2015
One key requirement for fountain (rateless) coding schemes is to achieve a high intermediate symbol recovery rate. Recent coding schemes have incorporated the use of a feedback channel to improve intermediate performance of traditional rateless codes ...

Fighting terrorism: How to position rapid response teams?

Naval Research Logistics (NRL), Volume 71, Issue 5, Page 709-727, August 2024.
Abstract In light of recent terrorist attacks, we introduce and study a Stackelberg game between a government and a terrorist. In this game, the government positions a number of heavily‐armed rapid response teams on a line segment (e.g., a long boulevard or shopping avenue) and then the terrorist attacks a location with the highest potential impact of ...

Evaluating the Rheological Controls on Topography Development During Craton Stabilization: Objective Approaches to Comparing Geodynamic Models

Journal of Geophysical Research: Solid Earth, Volume 129, Issue 4, April 2024.
Abstract Surface topography is an important yet largely neglected aspect of the early evolution of cratons. The lateral accretion of cratonic nuclei inevitably forms orogenic belts that subsequently provide a sediment source for large, resource‐rich intracratonic basins, but to date, geodynamic models have focused exclusively on lithospheric root ...

Raptor Codes in the Low SNR Regime

, 2015
In this paper, we revisit the design of Raptor codes for binary input additive white Gaussian noise (BIAWGN) channels, where we are interested in very low signal to noise ratios (SNRs).

Significant Midlatitude Bubble‐Like Ionospheric Super‐Depletion Structure (BLISS) and Dynamic Variation of Storm‐Enhanced Density Plume During the 23 April 2023 Geomagnetic Storm

Space Weather, Volume 22, Issue 3, March 2024.
Abstract This paper investigates the midlatitude ionospheric disturbances over the American/Atlantic longitude sector during an intense geomagnetic storm on 23 April 2023. The study utilized a combination of ground‐based observations (Global Navigation Satellite System total electron content and ionosonde) along with measurements from multiple ...

Infinitely many solutions for a class of fractional equations via variant fountain theorems

Boletim da Sociedade Paranaense de Matemática
This article is concerned with a class of fractional type equation involving an anisotropic operator and potential of the form $$(-\Delta_x)^s u-\Delta_yu+\Phi(x,y)u=g(x,y,u),\;(x,y)\in\mathbb{R}^n\times\mathbb{R}^m.$$ By means of the variational method and the variant fountain theorems, we investigate the existence of infinitely many high or small ...

Zigzag Decodable Fountain Codes

, 2016
This paper proposes a fountain coding system which has lower space decoding complexity and lower decoding erasure rate than the Raptor coding systems. The main idea of the proposed fountain code is employing shift and exclusive OR to generate the output ...

Multiplicity of Quasilinear Schrödinger Equation

Journal of Function Spaces, 2020
In this paper, we study the quasilinear Schrödinger equation involving concave and convex nonlinearities. When the pair of parameters belongs to a certain subset of ℝ2, we establish the existence of a nontrivial mountain pass-type solution and infinitely

Multiplicity of Solutions for a Class of Kirchhoff–Poisson Type Problem

Abstract and Applied Analysis, Volume 2024, Issue 1, 2024.
In this paper, we use the fountain theorems to investigate a class of nonlinear Kirchhoff–Poisson type problem. When the nonlinearity f satisfies the Ambrosetti–Rabinowitz’s 4‐superlinearity condition, or under some weaker superlinearity condition, we establish two theorems concerning with the existence of infinitely many solutions.
