DESAIN KONTROL PENGOBATAN PADA MODEL SIRD UNTUK PENYEBARAN VIRUS COVID-19 MENGGUNAKAN BACKSTEPPING

In this article, we present a control design on a SIRD model with treatment in infected individuals. The SIRD model with treatment is obtained from literature study and the parameter model is obtained  from covid-19 daily case in the Riau p...

A Game—Theoretic Model for a Stochastic Linear Quadratic Tracking Problem

In this paper, we solve a stochastic linear quadratic tracking problem. The controlled dynamical system is modeled by a system of linear Itô differential equations subject to jump Markov perturbations. We consider the case when there are tw...

Investigating Spatial Effects through Machine Learning and Leveraging Explainable AI for Child Malnutrition in Pakistan

While socioeconomic gradients in regional health inequalities are firmly established, the synergistic interactions between socioeconomic deprivation and climate vulnerability within convenient proximity and neighbourhood locations with heal...

Tourism Demand Elasticities by Income and Prices of International Market Regions: Evidence Using Vietnam’s Data

This study aims to determine tourism demand elasticities by income and prices of regions, as well as total international markets. It is deployed to a total of 10 major source markets and two separate regions, from Asia and intercontinental ...

Energy Minimum Design and Systematic Analysis of the Reactive Dividing Wall Column

The reactive dividing wall column (RDWC) is a highly integrated apparatus, which combines a reactive distillation and a dividing wall column in one single shell. Thus, high savings in investment as well as operational costs can be achieved ...

Mediating role of neutrophil-percentage-to-albumin ratio in the association between stroke and heart failure among U.S. adults

Background: Stroke is an independent risk factor for heart failure (HF), and they are both linked to systemic inflammation. The neutrophil-percentage-to-albumin ratio (NPAR) is a novel inflammation biomarker. However, it is unclear whether ...

Soft x-ray high-harmonic generation in an anti-resonant hollow core fiber driven by a 3 μm ultrafast laser

High-harmonic upconversion driven by a mid-infrared femtosecond laser can generate coherent soft x-ray beams in a tabletop-scale setup. Here, we report on a compact ytterbium-pumped optical parametric chirped pulse amplifier (OPCPA) laser s...

Second hyperpolarizability of hexagonal graphene quantum dots: Effects of size and structural defects

Graphene quantum dots (GQDs) are nanosized fragments of graphene containing a bandgap caused by edge effects and quantum confinement. These features enable GQDs to have attractive photonics applications. During the preparation of graphene n...

High-speed nonlinear focus-induced photoresponse in amorphous silicon photodetectors for ultrasensitive 3D imaging applications

Abstract A large and growing number of applications benefit from simple, fast and highly sensitive 3D imaging sensors. The Focus-Induced Photoresponse (FIP) can achieve 3D sensing functionalities by simply evaluating the irradiance dependen...

Quantum Image Encryption Scheme Using Arnold Transform and S-box Scrambling

The paper proposes a lossless quantum image encryption scheme based on substitution tables (S-box) scrambling, mutation operation and general Arnold transform with keys. First, the key generator builds upon the foundation of SHA-256 hash wi...

Tripartite Linear Relationships Among Job Satisfaction, Organisational Commitment, and Organisational Citizenship Behaviour in Non-Western Settings: A Meta-Analysis and Meta-Regression Analysis

There is substantial evidence indicating a positive linear relationship among job satisfaction (JS), organisational commitment (OC), and organisational citizenship behaviour (OCB), with OC often serving as a mediating variable. The interact...
