Abstract Spinal muscular atrophy (SMA) is caused by dysfunction of the alpha motor neurons of the spinal cord. It is an autosomal recessive disease associated to the SMN1 gene, located in the subtelomeric region of 5q13. A paralog SMN2 gene is located at the centromeric region of the same chromosome, which apparently originated by an ancestral inverted duplication occurring only in humans. The exon sequence differs in two nucleotides in exon 7 and exon 8, which leads to an SMN2 transcript that lacks exon 7 and results in a truncated protein. Part (10%) of the SMN2 transcripts avoids the splicing of… More >

Abstract The mechanical properties of living cells are known to be promising biomarkers when investigating the health and functions of the human body. Ionizing irradiation results in vascular injury due to endothelial damage. Thus, the current study objective was to evaluate the influence of continuous radiation doses on the mechanical properties of human umbilical vein endothelial cells (HUVECs), and to identify Young’s modulus (E) and viscoelastic behavior. Single-dose (0, 2, 4, 6, and 8 Gy) radiation was applied to HUVECs using a Cobalt-60 treatment machine in the current vitro irradiation study. Thereafter, a micropipette-aspiration technique was used to measure the elastic… More >

Abstract The slow steady rotation of a micropolar fluid spheroid whose shape deviates slightly from that of a sphere in concentric spheroidal container filled with Newtonian viscous fluid is studied analytically. The boundary conditions used are the continuity of velocity and stress components, and spin vorticity relation. The torque and wall correction factor exerted on the micropolar fluid spheroid is obtained. The dependence of wall correction factor on the micropolarity parameter, spin parameter, viscosity ratio and deformation parameter is studied numerically and its variation is presented graphically. In the limiting cases, the torque acting on solid spheroid in spheroidal container and… More >

Abstract A spike response model (SRM) based on the spikes generator circuit (SGC) of adaptive fuzzy spiking neurons (AFSNs) is developed. The SRM is simulated in MatlabTM environment. The proposed model is applied to a configuration of a fuzzy exclusive or (fuzzy XOR) operator, as an illustrative example. A description of the comparison of AFSNs with other similar methods is given. The novel method of the AFSNs is used to determine the value of the weights or parameters of the fuzzy XOR, first with dynamic weights or self-tuning parameters that adapt continuously, then with fixed weights obtained after training, finally with… More >

Abstract High speed spindle is the key component for high precision machine center. The optimum design of spindle cooling system have to achieve to avoid the high heat produce by the build-in motor that can make great damage to the spindle bearing systems. This paper presents a new solid-fluid coupling computing method for design high speed spindle cooling system. Energy equation has been formed for a control volume within the cooling channel to describe the heat absorbing by the coolant moving in a constant speed. Finite different method is applied to solve temperature rising in the coolant and coupled with a… More >

Abstract The robot hand applying force on a deformable object will result in a changing wrench space due to the varying shape and normal of the contact area. Design and analysis of a manipulation strategy thus depend on reliable modeling of the object's deformations as actions are performed. The first part of this talk is concerned with modeling of shell-like objects grasped by a robot hand. We present a formulation of extensional, shearing, and bending strains in terms of geometric invariants including the principal curvatures and vectors, and their related directional and covariant derivatives. A computational procedure is then offered for… More >

Abstract In this study, Electronic Speckle Pattern Interferometry (ESPI) technique was used to measure the surface displacement and strain fields around cracks in concrete beams. ESPI has high accuracy and can determine full-field deformations of concrete. However, tiny rigid-body movements of beam specimens can spoil the ESPI measurement and cause virtual deformations and false strains. Based on the theory of geometrical optics, this paper proposes a method to eliminate the false strains caused by rigid-body motion. The correction procedure was validated experimentally. Furthermore, the crack evolution in a pre-notched beam is presented. The critical minimum crack width of a microcrack is… More >

Abstract The aim of this paper was to establish the realistic breathing patterns in different exercise conditions by experimental measurement. Generally, the human inhalation rate varies from 15 L/min at rest to 135 L/min for intense exercise and the breathing cycles are varied with different exercise conditions. Previous author have used symmetric Weibel configuration to establish three realistic breathing patterns, i. e., resting (inhalation rate, 15 L/min), light activity (inhalation rate, 30 L/min), and moderate exercise (inhalation rate, 60 L/min). In this study, in addition to reconstructing the three realistic breathing patterns of above mention, we expand the establishment of the… More >
