Dynamical Analysis and Solutions of Nonlinear Difference Equations of Thirty Order

open access: yesUniversal Journal of Mathematics and Applications
Discrete-time systems are sometimes used to explain natural phenomena that happen in nonlinear sciences. We study the periodicity, boundedness, oscillation, stability, and certain exact solutions of nonlinear difference equations in this paper. Using the

Wavelet Analysis of Hydroclimatic Teleconnections and Precipitation Variability Over Ethiopia

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
This article investigates the variability of precipitation across Ethiopia by analyzing monthly and annual rainfall data from five stations representing the north, east, west, south, and central regions over a 31-year period (1987–2017).

Quasi-Periodic Crystals—The Long Road from Discovery to Acceptance

open access: yesRambam Maimonides Medical Journal, 2013
[Extract] Three surprising discoveries on the nature of matter and its properties were published in the mid-1980s. All these discoveries led to Nobel prizes. The first discovery was in 1985, when fullerenes were discovered by Robert F.

Effect of Out-Of-Hour Admission on Fluid Treatment of Emergency Department Patients with Suspected Infection; a Multicenter Post-Hoc Analysis

open access: yesArchives of Academic Emergency Medicine, 2023
Introduction: Sepsis is a life-threatening and common cause of Emergency department (ED) referrals. Out-of-hour staffing is limited in ED, which may potentially affect fluid administration.

Fractional Differential Equations with Impulsive Effects

open access: yesFractal and Fractional
This paper discusses impulsive effects on fractional differential equations. Two approaches are taken to obtain our results: either with fixed or changing lower limits in Caputo fractional derivatives.

Periodicity: A Characteristic of Heart Rate Variability Modified by the Type of Mechanical Ventilation After Acute Lung Injury

open access: yesFrontiers in Physiology, 2018
We present a novel approach to quantify heart rate variability (HRV) and the results of applying this approach to synthetic and original data sets. Our approach evaluates the periodicity of heart rate by calculating the transform of Relative Shannon ...

On the dynamical behaviors and periodicity of difference equation of order three

open access: yesJournal of New Results in Science, 2022
The major target of our research paper is to demonstrate the boundedness, stability and periodicity of the solutions of the following third- order difference equation $$ w_{n+1} = \alpha w_{n} +\frac {\beta+ \gamma w_{n_-2} }{\delta+\zeta w_{n-2}} , \;\;

Structure‐forward targeting of claudins with synthetic binders

open access: yesFEBS Letters, EarlyView.
Claudins form the paracellular barriers between epithelial and endothelial tissues at tight junctions and are targets for molecular binders with the goal of modulating barrier permeability. Claudin‐binding molecules are relevant in drug delivery or in altering claudin interactions with disease‐causing proteins.

Applicability of Evapotranspiration Models and Water Consumption Characteristics Across Different Croplands

open access: yesAgronomy
Estimating the actual evapotranspiration (ETc act) of cropland in arid areas, exploring the time trend, and analyzing periodic variation are the key to long-term assessment of water resource availability and regional drought.
