Model-based ensembles: Lessons learned from retrospective analysis of COVID-19 infection forecasts across 10 countries
(Elsevier, 2022-02)
[EN]Mathematical models of different types and data intensities are highly used by researchers, epidemiologists, and national authorities to explore the inherently unpredictable progression of COVID-19, including the effects ...
Entropy generation from convective–radiative moving exponential porous fins with variable thermal conductivity and internal heat generations
(Nature, 2022-02-02)
The performance and thermal properties of convective-radiative rectangular and moving exponential porous fins with variable thermal conductivity together with internal heat generation are investigated. The second law of ...
On the External Positivity of SISO Linear Dynamic Systems under a Class of Nonzero and Possibly Negative Initial Conditions Eventually Subject to Incommensurate Point Internal and External Delays
(MDPI, 2022-01-25)
The property of external positivity of dynamic systems is commonly defined as the non-negativity of the output for all time under zero initial conditions and any given non-negative input for all time. This paper investigates ...
On the Supervision of a Saturated SIR Epidemic Model with Four Joint Control Actions for a Drastic Reduction in the Infection and the Susceptibility through Time
(MDPI, 2022-01-28)
This paper presents and studies a new epidemic SIR (Susceptible–Infectious–Recovered) model with susceptible recruitment and eventual joint vaccination efforts for both newborn and susceptible individuals. Furthermore, ...
Dynamics of Oxygen-Plankton Model with Variable Zooplankton Search Rate in Deterministic and Fluctuating Environments
(MDPI, 2022-05-11)
It is estimated by scientists that 50–80% of the oxygen production on the planet comes from the oceans due to the photosynthetic activity of phytoplankton. Some of this production is consumed by both phytoplankton and ...
On the Stabilization of a Network of a Class of SISO Coupled Hybrid Linear Subsystems via Static Linear Output Feedback
(MDPI, 2022-03-25)
This paper deals with the closed-loop stabilization of a network which consists of a set of coupled hybrid single-input single-output (SISO) subsystems. Each hybrid subsystem involves a continuous-time subsystem together ...
On the Stabilization through Linear Output Feedback of a Class of Linear Hybrid Time-Varying Systems with Coupled Continuous/Discrete and Delayed Dynamics with Eventually Unbounded Delay
(MDPI, 2022-04-23)
This research studies a class of linear, hybrid, time-varying, continuous time-systems with time-varying delayed dynamics and non-necessarily bounded, time-varying, time-differentiable delay. The considered class of systems ...
Equivalence between the Existence of Best Proximity Points and Fixed Points for Some Classes of Proximal Contractions
(MDPI, 2022-09-13)
In the year 2014, Almeida et al. introduced a new class of mappings, namely, contractions of Geraghty type. Additionally, in the year 2021, Beg et al. introduced the concept of generalized F-proximal contraction of the ...
Generalized Cyclic p-Contractions and p-Contraction Pairs Some Properties of Asymptotic Regularity Best Proximity Points, Fixed Points
(MDPI, 2022-10-26)
This paper studies a general p-contractive condition of a self-mapping T on X, where (X ,d) is either a metric space or a dislocated metric space, which combines the contribution to the upper-bound of d(Tx , Ty), where x ...
A New Four-Step Iterative Procedure for Approximating Fixed Points with Application to 2D Volterra Integral Equations
(MDPI, 2022-11-14)
This work is devoted to presenting a new four-step iterative scheme for approximating fixed points under almost contraction mappings and Reich–Suzuki-type nonexpansive mappings (RSTN mappings, for short). Additionally, we ...
