Research in machine learning often focuses either on inductive learning learning from experience with minimal reliance on prior theory or, more recently, on explanation-based learning deducing general descriptions from theories with minimal reliance on experience. Theory revision unites these two concerns: one must revise one’s theory in the light of experience, but one must simultaneously use ...

this paper introduces a new method for accelerating current sluggish fem and improving memory demand in fem problems with high node resolution or bulky structures. like most of the numerical methods, fem results to a matrix equation which normally has huge dimension. breaking the main matrix equation into several smaller size matrices, the solving procedure can be accelerated. for implementing ...

background and aims. this study aimed to investigate release of nickel ion from three types of nickel-titanium-based wires in the as-received state and after immersion in a simulated oral environment. materials and methods. forty specimens from each of the single-strand niti (rematitan “lite”), multi-strand niti (speed supercable) and copper niti (damon copper niti) were selected. twenty specim...

In this paper, we show a general way to interpret the infrastructure of a global field of arbitrary unit rank. This interpretation generalizes the prior concepts of the giant-step operation and f -representations, and makes it possible to relate the infrastructure to the (Arakelov) divisor class group of the global field. In the case of global function fields, we present results that establish ...

traditional microbiology concepts are being renewed since the development of new microbiological technologies, such as, sequencing and large-scale genome analysis. since the entry into the new millennium, a lot of new information has emerged regarding the oral microbiome. this revision presents an overview of this renewed knowledge on oral microbial community acquisition in the newborn and on t...

We discuss the nonabelian world-volume action which governs the dynamics of N coincident Dp-branes. In this theory, the branes’ transverse displacements are described by matrix-valued scalar fields, and so this is a natural physical framework for the appearance of noncommutative geometry. One example is the dielectric effect by which Dp-branes may be polarized into a noncommutative geometry by ...
