Presented in the paper is the design, the simulation, the fabrication and the experiment of a new z-axis resonant accelerometer based on the electrostatic stiffness. The new z-axis resonant micro-accelerometer, which consists of a torsional accelerometer and two plane resonators, decouples the sensing movement of the accelerometer from the oscillation of the plane resonators by electrostatic st...

Let g(z; x) denote the diagonal Green's matrix of a self-adjoint m m matrix-valued Schrr odinger operator H = ? d 2 dx 2 Im + Q(x) in L 2 (R) m , m 2 N. One of the principal results proven in this paper states that for a xed x 0 2 R and all z 2 C + , g(z; x 0) and g 0 (z; x 0) uniquely determine the matrix-valued m m potential Q(x) for a.e. x 2 R. We also prove the following local version of th...

In lecture 29, we introduced the Euler angles as a framework for formulating and solving the equations for conservation of angular momentum. We applied this framework to the free-body motion of a symmetrical body whose angular momentum vector was not aligned with a principal axis. The angular moment was however constant. We now apply Euler angles and Euler’s equations to a slightly more general...

This Article contains an error in Figure 2c, where the y-axis 'μ g [Ru]/mg [cell protein]' is incorrectly labelled as 'ng [Ru]/mg [cell protein]'. The correct Figure 2c appears below as Figure 1.

Neutrophils are essential for maintaining innate immune surveillance under normal conditions, but also represent a major contributor to tissue damage during inflammation. Neutrophil homeostasis is therefore tightly regulated. Cxcr2 plays a critical role in neutrophil homeostasis, as Cxcr2(-/-) mice demonstrate mild neutrophilia and severe neutrophil hyperplasia in the bone marrow. The mechanism...

Problems of geometric probability for an arbitrary convex body of resolution in the euclidean space E3 has been investigated in [1]. In [9] Buffon’s problem is solved for a lattice of right-angled parallelepipeds in the 3-dimensional space. In this note we want to use the results in [5] for to solve problems of intersection for a particular lattice that we describe: the fundamental cell C0 of t...

If bone adapts to maintain constant strains and if on-axis yield strains in trabecular bone are independent of apparent density, adaptive remodeling in trabecular bone should maintain a constant safety factor (yield strain/functional strain) during habitual loading. To test the hypothesis that yield strains are indeed independent of density, compressive (n = 22) and tensile (n = 22) yield strai...
