Attitude and Gyro Bias Estimation Using GPS and IMU Measurements
, 2017 We propose an attitude and gyro-bias estimation scheme for accelerated rigid body systems using an inertial measurement unit (IMU) and a global positioning system (GPS).

Feedback control effect on the Lotka-Volterra prey-predator system with discrete delays
Advances in Difference Equations, 2017 In this paper, we study a Lotka-Volterra prey-predator system with feedback control. We establish sufficient conditions under which a unique positive equilibrium is globally stable.

Global stability in population models
Mathematical Modelling, 1982 AbstractIf g is a continuous map of an interval, the recursion xn + 1 = g(xn), n = 0, 1… converges globally if and only if the equation has only fixed points of g as roots. This leads to simple geometric conditions for global stability in discrete population models. Related conditions involving the Schwarzian derivative and curvature are discussed.

FEBS Letters, EarlyView.Exposure to common noxious agents (1), including allergens, pollutants, and micro‐nanoplastics, can cause epithelial barrier damage (2) in our body's protective linings. This may trigger an immune response to our microbiome (3). The epithelial barrier theory explains how this process can lead to chronic noncommunicable diseases (4) affecting organs ...

Global Properties of a Delay-Distributed HIV Dynamics Model Including Impairment of B-Cell Functions
Mathematics, 2019 In this paper, we construct an Human immunodeficiency virus (HIV) dynamics model with impairment of B-cell functions and the general incidence rate. We incorporate three types of infected cells, (i) latently-infected cells, which contain the virus, but ...

A Mathematical Study of a Generalized SEIR Model of COVID-19
SciMedicine Journal, 2020 In this work (Part I), we reinvestigate the study of the stability of the Covid-19 mathematical model constructed by Shah et al. (2020) [1]. In their paper, the transmission of the virus under different control strategies is modeled thanks to a ...

From omics to AI—mapping the pathogenic pathways in type 2 diabetes
FEBS Letters, EarlyView.Integrating multi‐omics data with AI‐based modelling (unsupervised and supervised machine learning) identify optimal patient clusters, informing AI‐driven accurate risk stratification. Digital twins simulate individual trajectories in real time, guiding precision medicine by matching patients to targeted therapies.

ITER Global Stability Limits [PDF]
Fusion Technology, 1991 The MHD stability limits to the ITER operational space have been examined with the PEST ideal stability code. Constraints on ITER operation have been examined for the nominal operational scenarios and for possible design variants. Rather than rely on evaluation of a relatively small number of sample cases, the approach has been to construct an ...

FEBS Letters, EarlyView.Tuberculosis remains a global health challenge and new therapeutic targets are required. Here, we characterized SseA, a sulfurtransferase from Mycobacterium tuberculosis involved in macrophage infection, and its interaction with the newly identified protein SufEMtb that activates SseA enzymatic activity.
