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 ...

Wafer‐Scale Atomically‐Thin Gold: Transferable Platform for Flexible Optoelectronics, Thermal Management and Bio‐Interfaces

Advanced Science, Volume 13, Issue 55, 5 October 2026.
Combining template stripping with a graphene‐inspired transfer yields continuous, transferable gold films at 6‐inch wafer scale with thicknesses approaching the atomic limit. The atomically smooth, near‐bulk‐quality films offer above 86% transmittance and sub‐20 Ω/square sheet resistance, serving as a universal platform for flexible optoelectronics ...

One Molecular Platform, Three Distinct Narrowband Organoboron TADF Emitters: A Divergent One‐Pot Strategy From Green to Red

Angewandte Chemie, Volume 138, Issue 39, 21 September 2026.
One platform–three emitters: Divergent one‐pot borylation of a single indolocarbazole platform exploits competing mono‐ and double‐borylation pathways to generate three spectrally distinct organoboron MR‐TADF emitters spanning green to red, enabling color‐tunable narrowband OLEDs with external quantum efficiencies over 30%.

Polymer‐Based Probabilistic Bits for Thermodynamic Computing

Advanced Physics Research, Volume 5, Issue 10, October 2026.
Electropolymerized conjugated polymers function as intrinsic entropy sources for probabilistic computing. Thermally driven conformational fluctuations of pendant triphenylamine groups produce stochastic resistance dynamics that are transduced into voltage‐gated probabilistic bits following logistic transfer functions identical to those of stochastic ...

PITCHFORK BIFURCATION, CRISIS, AND FLIP-FLOP OPERATION IN A 2-ELEMENT OPTICAL BISTABLE DEVICE

, 2011
[[abstract]]Flip-flop operation and the pitchfork bifurcation in a coupled element optical bistable device are studied. In the long delay limit, the dynamics is described by a two-dimensional mapping. Within a pitchfork bifurcation structure, a flip-flop

Dynamic Complexities in 2-Dimensional Discrete-Time Predator-Prey Systems with Allee Effect in the Prey

Discrete Dynamics in Nature and Society, 2016
The Allee effect is incorporated into a predator-prey model with linear functional response. Compared with the predator-prey which only takes the crowding effect and predator partially dependent on prey into consideration, it is found that the Allee ...

Standardized MRI‐Based Quantification of Epicardial Adipose Tissue Volume: Reproducibility and Agreement With Cardiac Computed Tomography

Journal of Magnetic Resonance Imaging, Volume 64, Issue 4, Page 1052-1063, October 2026.
ABSTRACT Background Epicardial adipose tissue volume (EATV) is increasingly recognized as a cardiometabolic risk marker associated with adverse outcomes. The most established approach for EATV quantification is cardiac computed tomography (CT). MRI offers a radiation‐free alternative allowing simultaneous assessment of myocardial function and tissue ...

Utility of Combining FIESTA‐C and MENSA for Facial Nerve Identification in Parotid Gland Surgery

The Laryngoscope, Volume 136, Issue 10, Page 4321-4326, October 2026.
This study evaluated the role of FIESTA‐C and MENSA in facial nerve identification and tumor localization in parotid gland surgery. The combination of FIESTA‐C and MENSA improved the accuracy of facial nerve identification and tumor localization compared to either sequence alone.

Bifurcation Analysis and Chaos Control in a Discrete-Time Parasite-Host Model

Discrete Dynamics in Nature and Society, 2017
A discrete-time parasite-host system with bifurcation is investigated in detail in this paper. The existence and stability of nonnegative fixed points are explored and the conditions for the existence of flip bifurcation and Neimark-Sacker bifurcation ...

A tipping point for tipping points

Oikos, Volume 2026, Issue 10, October 2026.
Tipping points (TPs) – often understood as abrupt changes to a system – have become a popular framework for ecology and environmental science across spatial and temporal scales. The underlying, quantitative foundation of TP theory is built on mathematical models from catastrophe and predator–prey theories.
