How much does language influence how we think? How far are the categories of our language contingent and culture-specific? Few questions are of greater significance to the social sciences. In this paper we attempt to demonstrate that linguistic semantics can address these questions with rigour and precision, by analysing some examples of cultural 'key words' in several languages. We want to arg...

in this paper we studied the thermal negativity in a two-qubit xx spin ½ chain model and xxx spin1/2 chain model(isotropic heisenberg model)spin-1/2 chain subjected to an external magnetic field inz direction. we calculate analytical relation for the thermal negativity for two qubit xx and xxx spinchain models in the external magnetic field. effects of the magnetic field and temperature on then...

This study explored touchscreen keyboards using high precision touchscreen strategies. Phase one evaluated three possible monitor positions: 30, 45, and 75 degrees from horizontal. Results indicate that the 75 degree angle, approximately the standard monitor position, resulted in more fatigue and lower preference ratings. Phase two collected touch bias and key size data for the 30 degree angle....

Context. Recently, much attention has been paid to the magnetic coupling (MC) process, which is supported by very high emissivity indexes observed in Seyfert 1 galaxy MCG-6-30-15 and GBHC XTE J1650-500. But the rotational energy transferred from a black hole is simply assumed to be radiated away from the surrounding accretion disk in black-body spectrum, which is obviously not consistent with t...

To describe statistical properties of solar coro-nal heating by microflares, nanoflares, and even smaller events, we consider a cellular automata model subject to uniform small scale driving and dissipation. The model consists of two elements, the magnetic field source supposed to be associated with the small scale hydrodynamic turbulence convected from the photosphere and local dis-sipation of...

We propose and discuss a method to analyze the structures of regular magnetic fields in external spiral galaxies with allowance for a multi-layer distribution of magnetic field and thermal electron density in the source of polarized radio emission. Our method allows for both horizontal and vertical components of the regular magnetic field. This approach we applied to the analysis of polarizatio...

Keywords magnetohydrodynamics (MHD) –turbulence –Sun: activity –Sun: magnetic fields We introduce on/offintermittencyinto amean field dynamo model by imposing stochastic fluctuations in either the alpha effect or through theinclusion of afluctuatingelectromotivef orce. Sufficiently strong smallscalefluctuations with time scales of theorder of 0.3–3 years can produce long term variations in thes...

In this paper, Gas insulated Switchgear bus bar has been investigated using 3D coupled multiphysics finite element analysis. The coupled field analysis involved consecutive multi-physics interactions. The interaction is characterized as a two-way sequential electromagnetic-thermal field coupling. The temperature rise in the GIS bus bar is due to the Joule’s losses in the conductor and induced e...

accumulating evidence suggests that self-renewal and differentiation capabilities reside only in a subpopulation of tumor cells, termed cancer stem cells (cscs), whereas the remaining tumor cell population lacks the ability to initiate tumor development or support continued tumor growth. in head and neck squamous cell carcinoma (hnscc), as with other malignancies, cscs have been increasingly sh...
