Bifurcation analysis of a multi-transverse-mode VCSEL [PDF]

, 2008
We study the behaviour of a multi-transverse-mode vertical-cavity surface-emitting laser subject to optical feedback in which the optical modes are coupled through the external round-trip. Starting from a delayed partial differential equation description

Immediate Growth Control in Response to Boiling Histotripsy is Prognostic for Intratumoral Immune Activation

Advanced Science, EarlyView.
Boiling Histrotripsy (BH), a mechanical form of focused ultrasound (FUS), allows for non‐invasive and non‐ionizing tissue destruction. Utilizing a BH treatment protocol that yielded bifurcating primary tumor growth responses, we found that immediate BH‐induced tumor growth control identifies tumors with acute reductions in antigen‐presenting cells (APC)

Recognition and analysis of symmetric dynamics and hidden dynamics of a three-dimensional global coupling discrete chaotic system based on the coordinate rotation transformation

四川大学学报. 自然科学版, 2022
A three-dimensional chaotic map is created with global coupling by substituting the mean field with standard 1-D Logistic map. The complex dynamics and hidden dynamics of coupled system are analyzed and identified by coordinate rotation transformation ...

Selective Catalytic Production of Urea: Unravelling the Pairwise Competition on p‐d Alloy Catalysts

Advanced Science, EarlyView.
Unraveling the complicated competition in urea electrosynthesis, this work investigates asymmetric p‐d alloys. We establish two stage‐specific descriptors, Anchoring Affinity and Coupling Propensity, to elegantly quantify thermodynamic bottlenecks.

Integrated Single‐Nucleus Multi‐Omics Atlases Reveal Lineage Plasticity and Regulatory Networks of Luminal Epithelial Cells During Mammary Gland Lactation and Involution

Advanced Science, EarlyView.
This study integrates single‐cell multi‐omics, spatial transcriptomics, and cross‐species comparative analyses to systematically characterize the cellular composition and differentiation trajectories of goat mammary epithelial cells, along with the gene regulatory networks and intercellular communication mechanisms governing these trajectories, thereby

Bifurcation diagram for the Rössler attractor

, 2016
The Rössler attractor is represented by the following set of ODEs: dx/dt=-(y+x); dy/dt=x+ay; dz/dt=b+xz-cz. The Demonstration plots the bifurcation diagram, where c is the bifurcation parameter, for values of parameters a and b set by the user.

Global dynamics of a modified hybrid Van der Pol-Rayleigh oscillator II

Electronic Journal of Differential Equations
In this article, we study a modified hybrid Van der Pol-Rayleigh oscillator. We consider bifurcation diagrams and global phase portraits in the Poincare disc under some restrictions on the parameters.
