When the shale gas reservoir is fractured, stress shadows can cause reorientation of hydraulic fractures and affect complexity. To reveal variation shadow with perforation spacing, numerical model between different spacing was simulated by extended finite element method (XFEM). The analyzed from two centers, fracture path, ratio length to spacing. simulations showed that rock at centers always ...

The flow of high-temperature and compositionally enriched material between mantle plumes nearby spreading centers influences up to 30% the global mid-ocean ridge system represents a significant, but currently unconstrained, flux volatiles out mantle. Here, we present new analyses H2O, F, Cl, S in basaltic glass chips from an archetypal region plume-ridge interaction, Galápagos Spreading Center ...

biosurfactants are surface-active compounds produced by microorganisms. in this study, we collected 60 inguinal area and ear canal samples from cows, sheep, and goats (each, 10 animals) and screened for biosurfactant-producing bacteria. we also determined the genera of culturing strains. fifty six hemolytic bacterial strains (27, 22 and 7, from cows, sheep and goats, respectively) were isolated...

During unmoderated discussions it is commonly observed that some people end up having more influence than seems justified by the actual quality of their contributions. In this paper, we propose and illustrate a spreading-activation architecture for modeling such differential influence. In our model, each participant’s level of influence vis-à-vis others in a discussion emerges out of the interp...

Online social networks enable fast and wide diffusion of rumors, which could be potential threats to the society. Understanding the rumor spreading mechanism is therefore essential. This demo presents an agent-patternbased model that can explain the spiky temporal diffusion pattern of rumors. The demo platform provides an interface allowing users to check a wide set of parameters contribute to ...

The cognitive architecture MicroPsi builds on a framework for simulating agents as neuro-symbolic spreading activation networks. These agents are situated in a simulation environment or fitted with robotic bodies. The current implementation of MicroPsi has been re-implemented from the ground up and is described here.
