Long-range gamma band EEG oscillations mediate information transmission between distant brain regions. Gamma band-based coupling may not be restricted to cortex-to-cortex communication but may include extracortical parts of the visual system. The retinogram and visual event-related evoked potentials exhibit time-locked, forward propagating oscillations that are candidates of gamma oscillatory c...

The dynamical behavior of a model for body fluids in response to an external electric field is computationally investigated for communication frequencies. The effect of an applied potential difference between two electrodes in a saline solution containing a rodlike macromolecule is studied by solving the Poisson and ion continuity equations simultaneously using the finite element method (FEM). ...

block heights and capillary continuity between matrix blocks play paramount role in the sensitivity analysis and therefore the history matching of cumulative oil production and production rate of carbonated fractured reservoirs. in this study, the influence of these parameters upon cumulative production and recovery factor of an iranian fractured reservoir were studied by the usage of a simulat...

In this paper, ω-closed sets and ω-open sets are used to define and investigate a new class of functions. Relationships between this new class and other classes of functions are established.

The main purpose of this paper is to introduce the concepts of η∗−sets, η∗∗−sets, η∗−continuity and η∗∗−continuity and to obtain decomposition of α−continuity and αgs−continuity in topological spaces.

The objective of this paper is to study some new analytical properties of credibility functions. We first discuss the continuity of credibility functions, and establish the sufficient and necessary conditions for the right continuity and left continuity of credibility functions. Furthermore, we study the absolute continuity of credibility functions and obtain some sufficient conditions for the ...

Virtual agents can provide a sense of continuity in applications that span long periods of time and incorporate diverse activities, media, and modalities. We describe the design of a virtual lactation educator agent that promotes breastfeeding in three settings, across different time spans, using a range of media and counseling techniques. The agent provides “interpersonal continuity of care” t...

Frequency domain blind source separation has the great advantage that the complicated convolution in time domain becomes multiple efficient multiplications in frequency domain. However, the inherent ambiguity of permutation of ICA becomes an important problem that the separated signals at different frequencies may be permuted in order. Mapping the separated signal at each frequency to a target ...

background : hepatitis b virus (hbv) is one of the most popular causes of chronic liver diseases through the world. there are approximately 350 million individuals infected with the hbv that 15 to 20 million of them are co-infected with hdv. it is known that co-existent infection with hdv tends to accelerate the progress of chronic hbv infection to chronic hepatitis, cirrhosis and hepatocellula...
