From June 26–28, the 120th China Stationery Fair (CSF) successfully concluded at the Shanghai New International Expo Centre — bringing together top brands and innovators across the Asia-Pacific ...

Rhiannon Giddens is a musical polymath. As someone who started out studying opera vocals, she’s best known for her skills as ...

Organic molecular crystals can respond to external stimuli such as heat, light, and mechanical force, making them attractive candidates for next-generation functional materials. However, predicting ...

IN a recent paper, entitled “Notes on Spherical Harmonics” (Proceedings of the Edinburgh Mathematical Society, vol. xxxii., 1914), Dr. John Dougall wrongly claims as new the expansion which he has ...

This post shows how to change what the Fn keys do in Windows 11/10. The Fn or the Function key is a meta-modifier key used to activate secondary functions or special features on certain keys. The ...

Abstract: We provide new criterion and a class of strict Lyapunov functions (SLFs) for time-varying systems (TVSs) with zero homogeneity. The definition of homogeneous auxiliary system is given, where ...

Abstract: In this article, we propose a new generalization for the notion of homogeneous functions. We show some properties and how it appears in some scenarios. Finally, we show how this ...

I want to identify the parameter q(x) in elliptic equation -du_xx + q(x)u =f, x\in [-1,1], where true solution u=sin(pi*x^2), q(x)=cos(x) is unknown. The following is the code: the train loss and test ...

We present a theoretical framework for immiscible incompressible two-phase flow in homogeneous porous media that connects the distribution of local fluid velocities to the average seepage velocities.
