1. Abstract In this design, the dual band dipole antenna feed network with wide bandwidth tapered microstrip balun is studied. The design and experimental results of low profile embedded microstrip dipole antenna with tapered microstrip balun shows fairly good performances. The feed network of the design with wider bandwidth and lower power loss tapered microstrip line to overlap coplanar strip...

We report compact, low-cost and efficient Cr:Colquiriite lasers that are pumped by high brightness tapered laser diodes. The tapered laser diodes provided 1 to 1.2 W of output power around 675 nm, at an electrical-to-optical conversion efficiency of about 30%. Using a single tapered diode laser as the pump source, we have demonstrated output powers of 500 mW and 410 mW together with slope effic...

We present tapered-slit filter devices for high-throughput viable circulating tumor cell (CTC) isolation and release. The membrane filter having an array of tapered-slits reduces the cell stress concentration at the edge of slit entrance, thus achieving viable CTC isolation with minimal stress. We fabricated the tapered-slit membrane from the UV exposure of spin-coated SU8 layers. The membrane ...

BACKGROUND Tapered grafts, which have a smaller diameter on the arterial side, have been increasingly used for arteriovenous fistula (AVF) formation. We compared the outcomes of 4-6-mm tapered and 6-mm straight forearm loop arteriovenous grafts. METHODS A total of 103 patients receiving forearm loop arteriovenous grafts between March 2005 and March 2015 were retrospectively analyzed and separ...

We present the results of a study comparing three directed-edge representations in node-link diagrams. Node-link diagrams are probably the most popular type of graph representations; nodes are depicted as dots and links as straight or curved lines connecting the nodes. An arrowhead placed at the end point of a link is traditionally used to indicate edge direction. However, Holten and Van Wijk [...

Potential applied at the two ends of a tapered capillary can produce an electric field and a pH gradient at the same time. These fields will effect electrophoretic separation, if the diameters of capillaries are not uniform. In some cases these gradients can be used to our advantage. For example, this approach provides a simple way to perform isoelectric focusing without carrier ampholytes as J...

The tapered implant-abutment interface is becoming more popular due to the mechanical reliability of retention it provides. Consequently, understanding the mechanical properties of the tapered interface with or without a screw at the bottom has been the subject of a considerable amount of studies involving experiments and finite element (FE) analysis. This paper focuses on the tapered implant-a...
