Recent information society policies have been paying much attention to the threat of a "digital divide". The gap between citizens from different socio-economic backgrounds with regard to their opportunities and abilities to access and use information and communication technologies is commonly regarded as a potential barrier for participation in the information society. This paper suggests a met...

We study the joint effect of thermal bath fluctuations and an external noise tuning activity of cytotoxic cells on the triggered immune response in a growing cancerous tissue. The immune response is assumed to be primarily mediated by effector cells that develop a cytotoxic activity against the abnormal tissue. The kinetics of such a reaction is represented by an enzymatic-like Michaelis-Menten...

The paper deals with the dynamics of the electrons in the first phase of the expansion of a spherical plasma irradiated by an ultraintense laser pulse, in which the ions can be considered as immobile. A simple model of ‘‘competitive escape’’ is proposed, in which the electrons leaving the ion sphere increase a potential barrier that prevents other electrons from escaping. © 2011 Elsevier Ltd.

Employing circular aperture probes for microwave imaging in the near-field has been proven to render high resolution images of a variety samples under test (SUT) when compared conventionally utilized rectangular probes. In this paper, it is proposed further enhance and sensitivity by loading (operating K-band frequency range) with resonant iris. It shown that probe exhibits confined localized d...

This study analyzes the air–water flow properties in overflow nappe jets. Data were measured several cross-sections of rectangular free-falling jets downstream a sharp-crested weir, with maximum fall distance 2.0 m. The obtained using conductivity phase-detection probe. Furthermore, back-flushing Pitot-Prandtl probe was used order to obtain velocity profiles. Five specific flows rates analyzed,...

a new hybrid modal-moment method is proposed to calculate fields penetrated through small apertures on rectangular metallic enclosures. first, the method of moments is used to numerically solve the governing electric field integral equation for the equivalent two-dimensional surface-current distributions on the surface of metallic enclosure including any number of rectangular apertures of arbit...

Atomic force microscope (AFM) is commonly used for three-dimensional characterization of the surface morphology structures at nanoscale, but “Inflation effect” tip an important factor affecting accuracy. A characterizer has advantages in situ measurement, higher accuracy probe inversion results, and relatively simple fabrication process. In this paper, we developed a rectangular based on multil...

In a continued quest to monitor subsecond surface dynamics on the atomic scale and improve imaging resolution, FAST module accelerate existing scanning probe microscopy setups was previously presented. Hereby, speedup is enabled by external electronics without modification of actual instrument. The resulting one-dimensional (1D) data stream, recorded while tip oscillates in sinusoidal motion, h...

Strong terahertz (THz) fields enhanced by subwavelength structures have great potential in manipulating the 6D phase space distribution of free electrons. Accurate measurement spatiotemporal THz field inside structure is essential for understanding physics behind such manipulation. Here, we demonstrate a method to directly probe metallic movie mode with ultrashort relativistic Information about...

The setting of this research is Bishop’s constructive mathematics. Let q be an anticongruence on a semigroup S with apartness. For q we say that it is an rectangular band anticongruence if S/q is a rectangular band. In paper [12] a construction of the maximal rectangular band anticongruence on a semigroup is described. This paper is continuation of that research. Let T be a detachable subsemigr...
