Computational analysis to assess hemodynamic forces in descending thoracic aortic aneurysms

The Journal of Physiology, EarlyView.
Abstract figure legend Left: Pre‐processing. First, we perform the segmentation of the Computer Tomography angiorgraphy (angio‐CT) scans of a healthy patient, obtaining the surface of a healthy thoracic aorta with a Type III aortic arch. Then, we build nine ideal configurations with Descending Thoracic Aortic Aneurysm (DTAA), varying the aortic arch ...

Complex Dynamics of a Discrete-Time Prey-Predator System With Leslie Type: Stability, Bifurcation Analyses and Chaos

, 2020
Dynamic behavior of a discrete-Time prey-predator system with Leslie type is analyzed. The discrete mathematical model was obtained by applying the forward Euler scheme to its continuous-Time counterpart.

A Multimodal Deep Learning Based Framework for Early and Accurate Diagnosis of Depression Using Electroencephalography and Event‐Related Potential Signals

Applied AI Letters, Volume 7, Issue 3, October 2026.
Cross Wavelet Transform (XWT) is combined with a pre‐trained AlexNet to extract rich time‐frequency features from non‐stationary EEG signals. Also, the proposed framework simultaneously extracts and integrates spatial (Node2vec), time‐frequency (XWT + AlexNet), and spectral (PSD + TSCN) features from EEG and ERP signals within a parallel architecture ...

Bifurcation analysis of surge and rotating stall in the Moore-Greitzer compression system [PDF]

, 2002
A simple compression system model, described by a set of three ordinary nonlinear differential equations (the Moore-Greitzer model) is studied using bifurcation analysis to give a qualitative understanding of the presence of surge and rotating stall ...

Recognition of fossil keratose sponges in carbonates using petrographic and machine‐learning classification

Sedimentology, Volume 73, Issue 6, Page 2246-2280, October 2026.
ABSTRACT Filamentous, anastomosing spar‐filled networks in Phanerozoic carbonates have been interpreted as the mineralised remains of keratose (non‐spiculate) sponges, yet their recognition remains contested because fabrics of broadly similar appearance may arise from microbial, diagenetic or physical processes. This study combines direct fossil–modern

Chaos inducement and enhancement in two particular nonlinear MAPS using weak periodic/quasiperiodic perturbations

, 2006
Weak periodic perturbation has long been used to suppress chaos in dynamical systems. In this paper, however, we demonstrate that weak periodic or quasiperiodic perturbation can also be used to induce chaos in nonchaotic parameter ranges of chaotic maps,

Impacts of disturbances on bifurcation behaviors in an interconnected power systems

AIP Advances
The reliable and stable operation of the power grid is crucial to the national economy, and the existing complex nonlinear phenomena related to disturbances, such as chaotic oscillation accompanied by bifurcation behaviors, are potential threats to ...

Complexity Analysis of a Master-Slave Oligopoly Model and Chaos Control

Abstract and Applied Analysis, 2014
We establish a master-slave oligopoly game model with an upstream monopoly whose output is considered and two downstream oligopolies whose prices are considered.

T(w)o Patch or Not T(w)o Patch: A Novel Biocontrol Model

Mathematical Methods in the Applied Sciences, Volume 49, Issue 13, Page 14697-14743, 15 September 2026.
ABSTRACT A number of top‐down biocontrol models have been proposed where the introduced predators' efficacy is enhanced via the provision of additional food (AF). However, if the predator has a pest‐dependent monotone functional response, pest extinction is unattainable. In the current manuscript, we propose a model where a predator with pest‐dependent

Living in the E‐Commerce Countryside: Place Attachment and the Negotiation of Place Change in Rural China

Journal of Community &Applied Social Psychology, Volume 36, Issue 5, September/October 2026.
ABSTRACT Rapid digitization is transforming rural communities worldwide, yet current scholarship remains dominated by macro‐economic analyses. This study examines the micro‐dynamics of engagement in E‐commerce villages through the lens of lived experience.
