Doughnut shaped hybridization patterns on DNA microarrays are mainly allocated to spotting or drying artifacts. The present study reports on results obtained from four different approaches that when combined generate a better view on the occurrence of these patterns. This study points out that doughnuts are not only formed during the spotting and drying(More)
We report on the use of a free-space optical module to establish multi-channel intra-chip optical interconnections on an opto-electronic field programmable gate-array (OE-FPGA). The optical component was prototyped and replicated in our labs to provide 2x8 parallel channels. After careful alignment of the free-space module on the OE-FPGA 4 channels were(More)
Compressive sensing is a mathematical framework, which seeks to capture the information of an object using as few measurements as possible. Recently, it has been applied to holography, where the most frequently used reconstruction method is l<sub>1</sub>-norm minimization with the Haar wavelet as the sparsifying operator. In this work, we promote the CDF(More)
During the spreading of a liquid over a solid substrate, the contact line can stay pinned at sharp edges until the contact angle exceeds a critical value. At (or sufficiently near) equilibrium, this is known as Gibbs' criterion. Here, we show both experimentally and theoretically that, for completely wetting volatile liquids, there also exists a(More)
One of the grand challenges in solving the interconnection bottlenecks at the printed circuit board (PCB) and multi-chip-module (MCM) level, is to adequately replace the PCB and intra-MCM galvanic interconnects with high-performance, low-cost, compact and reliable micro-photonic alternatives. Therefore we address the following components in this paper: 1)(More)
