The atomic cluster expansion (ACE) was proposed recently as a new class of data-driven interatomic potentials with formally complete basis set. Since the development any potential requires careful selection training data and thorough validation, an automation construction dataset well indication model's uncertainty are highly desirable. In this work, we compare performance two approaches for AC...

these are notes from introductory survey lectures given at the institute for studies in theoretical physics and mathematics (ipm), teheran, in 2008 and 2010. we present the definition and the fundamental properties of fomin-zelevinsky’s cluster algebras. then, we introduce quiver representations and show how they can be used to construct cluster variables, which are the canonical generators of ...

Personalization of web-based content coupled with a proliferation of heterogeneous terminals and devices will dramatically increase the need for computational services. Current trends towards thin clients make it difficult to perform such computation at the terminal end, while service providers frequently out-source computation, especially when operating under varying load. Today, most computat...

An active Web cluster system is an active network that has a collection of locally distributed servers that are interconnected by active switches, providing a Web application service. In this paper, we introduce the ALBM (Adaptive Load Balancing and Management) active cluster system that provides proactive management. The architecture of the ALBM active cluster and its underlying components are...
