Generalising the logistic map through the $q$-product

, 2011
We investigate a generalisation of the logistic map as $ x_{n+1}=1-ax_{n}\otimes_{q_{map}} x_{n}$ ($-1 \le x_{n} \le 1$, $01$ at the edge of chaos, particularly at the first critical point $a_c$, that depends on the value of $q_{map}$.

Security Improve in ZigBee Protocol Based on RSA Public Algorithm in WSN [PDF]

Engineering and Technology Journal, 2019
ZigBee is consuming low energy and providing the protection in Wireless Sensor Networks. ZigBee pro is supporting most applications. In spite of improved the security, ZigBee pro weak in key administration. In this paper, we depend on Logistic Map Diffie

Logistic map driven by dichotomous noise [PDF]

Physical Review E, 1993
Bifurcation diagrams and invariant densities are computed and interpreted for a logistic map driven by dichotomous noise. Two deterministic limits are analyzed. Changes in the stability of such a system, when varying the correlation time of the noise, are numerically studied.

Chaos of Exponential Logistic Map

Discrete Dynamics in Nature and Society
In this paper, chaos of a new exponential logistic map modulated by Gaussian function is investigated. Firstly, the stability of the fixed point is analyzed, and the occurrence of period doubling bifurcation in the system is verified theoretically ...

Inpatient Food Insecurity and Pediatric Hematology Oncology Hospitalization Outcomes

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Children with cancer and blood disorders are at risk for food insecurity (FI). We aimed to describe the association of inpatient food insecurity (IFI) and hospitalization outcomes among patients admitted to the pediatric hematology oncology service. Of 325 caregivers screened for IFI, 60 (18.6%) screened positive.

Weak noise approach to the logistic map

, 2004
Using a nonperturbative weak noise approach we investigate the interference of noise and chaos in simple 1D maps. We replace the noise-driven 1D map by an area-preserving 2D map modelling the Poincare sections of a conserved dynamical system with ...

‘They Need to Hear You Say It’: Healthcare Professionals’ Perspectives on Barriers and Enablers to End‐of‐Life Discussions With Adolescents and Young Adults With Cancer

Pediatric Blood &Cancer, EarlyView.
ABSTRACT End‐of‐life conversations with adolescents and young adults (AYAs) with cancer rarely occur without the guidance of healthcare professionals. As a part of the ‘Difficult Discussions’ study, focused on palliative care and advance care planning discussions with AYAs with cancer, we investigated the factors that healthcare professionals identify ...

Dietary Protein Intake and Peritoneal Protein Losses in Peritoneal Dialysis Patients

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Peritoneal dialysis (PD) patients lose protein in their waste dialysate, potentially increasing their risk for malnutrition. We wished to determine whether there was any association between losses and dietary protein intake (DPI). Methods DPI was assessed from 24‐h dietary recall using Nutrics software.

Generalized logistic map and its applications

AIP Advances
This study examines the generalized logistic map, a mathematical model defined by a recurrence relation with parameters that govern its dynamics. By broadening the scope of the classical logistic map, this generalized form captures a wider range of ...

Using the Logistic Coupled Map for Public Key Cryptography under a Distributed Dynamics Encryption Scheme

Information, 2018
Nowadays, there is a high necessity to create new and robust cryptosystems. Dynamical systems have promised to develop crypto-systems due to the close relationship between them and the cryptographic requirements.
