mountains and trees have many similarities. in this way, simorgh of shahnameh shifts from the tree of vispobish to alborz mountain. if simorgh has spiritual existence in avesta, a devilish side has been added to it in shahnameh. in avesta, it lives on a tree, but in shahnameh we find him on alborz mountain. all the researches done on shahnameh and iranian mythology did not pay any attention to ...

This paper describes an implementation of the Discrete Fourier Transform (DFT) and the Inverse Discrete Fourier Transform (IDFT). We show how the computation of the DFT and IDFT may be performed in Java and show why such operations are typically considered slow. This is a multi-part paper, in part 2, we discuss a speed up of the DFT and IDFT using a class of algorithms known as the FFT (Fast Fo...

Inspired by the differential-growth-driven morphogenesis of leaves, flowers, and other tissues, there is increasing interest in artificial analogs of these shape-shifting thin sheets made of active materials that respond to environmental stimuli such as heat, light, and humidity. But how can we determine the growth patterns to achieve a given shape from another shape? We solve this geometric in...

Pain is a highly personal experience that varies substantially among individuals. In search of an anatomical correlate of pain sensitivity, we used voxel-based morphometry to investigate the relationship between grey matter density across the whole brain and interindividual differences in pain sensitivity in 116 healthy volunteers (62 women, 54 men). Structural magnetic resonance imaging (MRI) ...

Phase-shifting interferometry is a coherent optical method that combines high accuracy with high measurement speeds. This technique is therefore desirable in many applications such as the efficient industrial quality inspection process. However, despite its advantageous properties, the inference of the object amplitude and the phase, herein termed wavefront reconstruction, is not a trivial task...

A bstract We derive parametric integral representations for the general n -point function of scalar operators in momentum-space conformal field theory. Recently, this was shown to be expressible as a generalised Feynman with topology an ( ? 1)-simplex, featuring arbitrary cross ratios. Here, we show all graph polynomials can expressed terms first and second minors Laplacian matrix simplex. Comp...

The momenta of τ decay products in the reaction e + e − → τ + τ − do not constrain the τ direction unambiguously. It is shown how the measurement of tracks of hadrons from semileptonic τ decays, in particular their relative impact parameters, allows to resolve this ambiguity.
