We propose a model of a joint spread of heroin use and Black Tea HIV infection.The unique disease-free equilibrium always exists and it is stable if the basic reproduction numbers of heroin use and HIV infection are both less than 1.The semi-trivial equilibrium of HIV infection (heroin use) exists if the basic reproduction number of HIV infection (
Bifurcation and complex dynamics of a discrete-time predator-prey system involving group defense
In this paper, we investigate the Cosmetics dynamics of a discrete-time predator-prey system involving group defense.The existence and local stability of positive fixed point of the discrete dynamical system is analyzed algebraically.It is shown that the system undergoes a flip bifurcation and a Neimark-Sacker bifurcation in the interior of R+2 by
Robust and consistent biomarker candidates identification by a machine learning approach applied to pancreatic ductal adenocarcinoma metastasis
Abstract Background Machine Learning (ML) plays a crucial role in biomedical research.Nevertheless, it still has limitations in data integration and irreproducibility.To address these challenges, robust methods Hat Brushes are needed.Pancreatic ductal adenocarcinoma (PDAC), a highly aggressive cancer with low early detection rates and survival rate
Mainstreaming zero carbon: lessons for built-environment education and training
Highlights Education and training are identified as a key means of reducing carbon emissions from buildings to help address the climate emergency.Institutional, industry and organisational responses are shown to be failing in this regard.This editorial introduces the themes and individual papers in the special issue and then explores the current st
Revisiting the Kazakhstan natural sorbents modification
Kazakhstan ranks second in the world in natural uranium reserves and a leading position in its production.Hydrometallurgical processing of uranium raw materials results in a significant amount of liquid technogenic wastes containing radionuclides.Sorption cleaning methods for these wastes are the most effective ones.However, the high Plastic Storag
