The split-spectrum amplitude-decorrelation angiography (SSADA) algorithm was recently developed as a method for imaging blood flow in the human retina without the use of phase information. In order to enable absolute blood velocity quantification, in vitro phantom experiments are performed to correlate the SSADA signal at multiple time scales with various preset velocities. A linear model relat...

ABSTRACT We demonstrate a droplet-based microfluidic device in which in-droplet magnetic bead separation is performed in continuous-flow. Two droplets containing different solution for the magnetic bead separation are generated in pair-wise manner. Sequential fusion of droplets occurs by a geometrical structure. The magnetic beads are deflected by externally applied magnetic force from one side...

Using coordinates that manifest the S-S split of the base, we study D3-branes localized on the three-sphere in the Klebanov-Strassler background. We find a numerical solution for the warp factor and show the emergence of the AdS throat near the stack. In the dual gauge theory, this corresponds to an RG flow along the mesonic branch. We demonstrate how the cubic superpotential of the N = 4 SYM t...

Grammar Flow Analysis (GFA) is a computation framework that can be applied to a large number of problems expressed on context-free grammars. In this framework, as was done on programs with Data Flow Analysis, those problems are split into a general resolution procedure and a set of speciic propagation functions. This paper presents a number of improvement techniques that act on the resolution p...

Networked reconfiguration is an enabling technology for cost effective service deployment and maintenance. A hardware virtual machine to enable this networked reconfiguration is presented. An abstract FPGA model is the core of such a hardware virtual machine. Based on this abstract FPGA model, the traditional implementation flow of FPGA has been separated into two parts: the service provider’s ...

Droplet microfluidic techniques can perform large numbers of single molecule and cell reactions but often require controlled, periodic flow to merge, split, and sort droplets. Here, we describe a simple method to convert aperiodic flows into periodic ones. Using an oil extraction module, we efficiently remove oil from emulsions to readjust the droplet volume fraction, velocity, and packing, pro...

The split-coloring problem is a generalized vertex coloring problem where we partition the vertices into a minimum number of split graphs. In this paper, we study some notions which are extensively studied for the usual vertex coloring and the cocoloring problem from the point of view of split-coloring, such as criticality and the uniqueness of the minimum split-coloring. We discuss some proper...

The SAM architecture is an enhanced von Neumann processor that contains inexpensive features for supporting data flow style of parallelism. The architecture gets is name from the basic instructions for supporting parallelism, Split and Merge. It is shown that these instructions can be used to implement the parallel structure of an arbitrary acyclic data flow graph. Features for supporting dynam...
