Topological Properties of International Commodity Market: How Uncertainty Affects the Linkages?
Agribusiness, EarlyView.ABSTRACT The study aims to explore the network topology of the international commodity market by examining the interconnections among 21 commodity futures across various categories, including energy, precious and industrial metals, and agriculture. We analyze the market structure of these commodity futures under both low and high uncertainty conditions

Global dynamics of the May-Leonard system with a Darboux invariant
Electronic Journal of Differential Equations, 2020 We study the global dynamics of the classic May-Leonard model in $\mathbb{R}^3$. Such model depends on two real parameters and its global dynamics is known when the system is completely integrable.

Farmers’ Protests in Germany: Media Coverage and Types of Bias
Agribusiness, EarlyView.ABSTRACT The German farmers’ protests of 2024 sparked widespread media coverage and public debate. Yet, media coverage was not always positive, reflecting the media's attention‐seeking and selective focus. Occurrences of farmers blocking media outlets reflected distrust in how their concerns were portrayed.

AIChE Journal, EarlyView.Abstract Emulsion separation remains a persistent challenge in chemical and process industries due to the metastable nature of dispersed droplets. In gravity separators, the overall separation rate is governed by the formation of a densely packed zone (DPZ) of deforming and coalescing droplets that mediates between the dispersed and continuous phases ...

Advanced Intelligent Discovery, EarlyView.Capacitive, charge‐domain compute‐in‐memory (CIM) stores weights as capacitance,eliminating DC sneak paths and IR‐drop, yielding near‐zero standbypower. In this perspective, we present a device to systems level performance analysis of most promising architectures and predict apathway for upscaling capacitive CIM for sustainable edge computing ...

Global monostability of a genetic toggle switch system
四川大学学报. 自然科学版, 2017 In this paper the global qualitative properties of a system which models a genetic toggle switch with cooperativties $1$ are given. Firstly it is proved that the system has a unique equilibrium, which is a stable node.

New sufficient conditions for a center and global phase portraits for polynomial systems
Publicacions Matemàtiques, 1996 The authors consider a system \[ x'=P(x,y),\quad y'=Q(x,y), \] where \(P,Q\) are polynomials in \(x,y\). They study the function \(1/M(x,y)\) (where \(M\) is an integrating factor for the system) to find new explicit conditions under which the system has a center. For cubic systems, global phase portraits in the case of center existence are described.

Global phase portraits of Kukles differential systems with homogenous polynomial nonlinearities of degree 5 having a center [PDF]
Topological Methods in Nonlinear Analysis, 2016 We provide 22 different global phase portraits in the Poincaré disk of all centers of the so called Kukles polynomial differential systems of the form ẋ = -y, ẏ = x + Q5(x, y), where Q5 is a real homogeneous polynomial of degree 5 defined in R2.
