The formation of segmental grooves during mid embryogenesis in the Drosophila epidermis depends on the specification of a single row of groove cells posteriorly adjacent to cells that express the Hedgehog signal. However, the mechanism of groove formation and the role of the parasegmental organizer, which consists of adjacent rows of hedgehog- and wingless-expressing cells, are not well underst...

Standing balance control relies on multisensory feedback, but little is known about the influence of periodically varying sounds on this process. The level of sensorimotor activation has been shown to be highly correlated with the concept of musical groove. We presented musical stimuli with high and low groove ratings to participants (N=40) as center of pressure (CoP) was recorded using a force...

this paper aims to assess the application of support vector machine (svm) regression in order to analysis flexible pavements. to this end, 10000 four-layer flexible pavement sections consisted of asphalt concrete layer, granular base layer, granular subbase layer, and subgrade soil were analyzed under the effect of standard axle loading using multi-layered elastic theory and pavement critical r...

In this paper, the stress intensity factor (SIF) expression for defected butt welds containing undercut and inclined lack of penetration (LOP) subject to far-field tensile stress is derived. Some of the standards such as ISO 5817 and BS EN 25817 have specified allowable limits for the length of the undercut and LOP defects and for the height of the weld. In addition, EN 29692 standard has deter...

Tactile friction which occurs between the surfaces of hand-operated products and the user as well as the user’s perception of surface characteristics are both very important considerations for the function of engineering products. While the use of surface texture is known to greatly influence these properties, the effect of the governing textural parameters on the friction mechanisms between a ...

We consider the problem of contact interaction several elastic bodies with nonlinear Winkler surface layers. To solve a variational equation nondifferentiable operator corresponding to this problem, we propose use implicit two-point combined differential-difference parallel iterative Robin-type domain decomposition algorithms. software realization these algorithms for case plane problems based ...

This paper describes the GROOVE solution to the “Class Diagram Restructuring” case study of the Tool Transformation Contest 2013 [4]. GROOVE [5, 2] is designed to support state space exploration and model checking of dynamically evolving systems; however, as we will show in this contribution, it can also be used to demonstrate graph transformations as a basis for model transformation. GROOVE’s ...

Additively manufactured polymer tools are evaluated for use in metal forming as prototype and the attempt to make sheet more attractive small production volumes. Printing materials, strategies accuracies presented before tested V-bending groove pressing of 1 mm aluminum sheets. The shows that change surface topography during until a steady state is reached at around five strokes. geometrical ac...

Alternative models have been presented to provide explanations for the sequence-dependent variation of the DNA minor groove width. In a structural model groove narrowing in A-tracts results from direct, short-range interactions among DNA bases. In an electrostatic model, the narrow minor groove of A-tracts is proposed to respond to sequence-dependent localization of water and cations. Molecular...
