Prediction of Hydrodynamic Parameters of the State of the Bottomhole Zone of Wells Using Machine Learning Methods

Georesursy
The relevance of the development of a methodology for the operational assessment of the bottomhole formation zone (the permeability of the bottom-hole formation zone and the skin factor) is primarily due to economic considerations, since existing ...

Target Cell-Specific Short-Term Plasticity in Local Circuits

Frontiers in Synaptic Neuroscience, 2013
Short-term plasticity (STP) denotes changes in synaptic strength that last up to tens of seconds. It is generally thought that STP impacts information transfer across synaptic connections and may thereby provide neurons with, for example, the ability to ...

Natural Emergence of Clusters and Bursts in Network Evolution

Physical Review X, 2013
Network models with preferential attachment, where new nodes are injected into the network and form links with existing nodes proportional to their current connectivity, have been well studied for some time.

Simulation of Z(3) walls and string production via bubble nucleation in a quark-hadron transition

, 2010
We study the dynamics of confinement-deconfinement (C-D) phase transition in the context of relativistic heavy-ion collisions within the framework of effective models for the Polyakov loop order parameter.

Learning by observing [PDF]

We introduce a network formation model based on the idea that individuals engage in production (or decide to participate in an action) depending on the similar actions of the people they observe in a society. We differentiate from the classical models of

Analyzing Topological Indices and Heat of Formation for Copper(II) Fluoride Network via Curve Fitting Models

Applied Artificial Intelligence
One of the most important fields in current materials research is the examination of materials through the prism of topological indices. An extensive statistical investigation of topological indices relevant to the characterization of copper(II) fluoride

Existence of Nash Networks in One-Way Flow Models [PDF]

This paper addresses the existence of Nash equilibria in one-way flow or directed network models in a number of different settings. In these models players form costly links with other players and obtain resources from them through the directed path ...

Graph Transformations and Game Theory: A Generative Mechanism for Network Formation [PDF]

, 2008
Many systems can be described in terms of networks with characteristic structural properties. To better understand the formation and the dynamics of complex networks one can develop generative models.
