We present a novel method for independently controlling multiple stress-engineered MEMS microrobots (MicroStressBots) through a single, global, control signal. Called Turning-rate Selective Control (TSC), this new technique employs designed variations in turning rates between individual microrobots to differentiate their motion. Despite all robots moving simultaneously and being identical excep...

Consider two graphs G1 and G2 on the same vertex set V and suppose that Gi has mi edges. Then there is a bipartition of V into two classes A and B so that for both i = 1, 2 we have eGi(A,B) ≥ mi/2 − √ mi. This answers a question of Bollobás and Scott. We also prove results about partitions into more than two vertex classes.

In this paper, first the available single charting methods, which have been proposed to detect simultaneous shifts in a single process mean and variance, are reviewed. Then, by designing proper simulation studies these methods are evaluated in terms of in-control and out-ofcontrol average run length criteria (ARL). The results of these simulation experiments show that the EWMA and EWMS methods ...

BACKGROUND The aim was to evaluate the reproducibility of glomerular filtration rate (GFR) measured with iohexol and its response to food in a direct and independent comparison with Cr-51-ethylenediaminetetraacetic acid (EDTA), and examine the influence of two different whole body scaling parameters, body surface area (BSA) and extracellular fluid volume (ECV). METHODS Fasting and non-fasting...

Achromatic metalens composed of arrays subwavelength nanostructures with spatially varying geometries is attractive for a number optical applications. However, the limited degree freedom in single layer achromatic metasurface design makes it difficult to simultaneously guarantee sufficient phase dispersion and high diffraction efficiency, which restricts bandwidth efficiency metalens. Here we p...

This work presents a new policy based security framework that is able handle simultaneously and coherently mandatory, discretionary and security property policies. One important aspect of the proposed framework is that each dimension of the security policies can be managed independently, allowing people playing different roles in an organization to define security policies without violating a g...
