The purpose of this research was to evaluate the maximum stress around osseointegrated implants and alveolar ridge, in a mandible with left partial resection through a photoelastic mandibular model. The first group consisted of two implants: traditional model (T), implants placed in the position of both canines; fulcrum model (F), implants placed in the position of left canine CL and right late...

Four-bar linkage mechanisms produced by many designers of knee joints for trans-femoral prostheses can provide knee rotation to permit walking only. In Afro-Asian countries people are accustomed to a squatting posture in their daily activities. A six-bar linkage knee-ankle mechanism trans-femoral prosthesis is described which was developed and fitted to an amputee. The motion patterns of the an...

In this paper, we adopt an extended relativized quark model to investigate the triply-heavy tetrquarks systematically. The mass spectra are obtained by solving four-body Hamiltonian including Coulomb potential, confining spin-spin interactions, and relativistic corrections. We find that all of tetraquarks lie above corresponding meson-meson thresholds, thus no stable one exists. particular, bes...

Properties of bars and bulges in the Hubble sequence are discussed, based on the analysis of 216 disk galaxies (S0s and spirals from NIRS0S and OSUBGS surveys, respectively). For that purpose we have collected together, and completed when necessary, the various analysis we have previously made separately for early and late types. We find strong photometric and kinematic evidence of pseudobulges...

The design of a knee joint is a key issue in robotics and biomechanics to improve the compatibility between prosthesis and human movements, and to improve the bipedal robot performances. We propose a novel design for the knee joint of a planar bipedal robot, based on a four-bar linkage. The dynamic model of the planar bipedal robot is calculated. Two kinds of cyclic walking gaits are considered...

The point here is the relatively simple argument that non-vanishing of an L-function on the line Re (s) = 1 implies an asymptotic result parallel to the application of ζ(s) to the Prime Number Theorem. This is based upon [Newman 1980]. In particular, this argument avoids estimates on the zeta function at infinity and also avoids Tauberian arguments. For completeness, we recall the standard clev...

The one-phase synthesis method using evolutionary or heuristic optimization algorithms can successfully solve the dimensional synthesis problems of path generating four-bar mechanisms discussed in the literature, where the input angles are usually used as design variables and the constraint of the rotational sequence of the input angles is necessary. However, there is still room for improvement...

The binding affinity of a curvature-sensing protein domain (N-BAR) is measured as a function of applied osmotic stress while the membrane curvature is nearly constant. Varying the osmotic stress allows us to control membrane tension, which provides a probe of the mechanism of binding. We study the N-BAR domain of the Drosophila amphiphysin and monitor its binding on 50 nm-radius vesicles compos...
