Three dimensional radiation dosimetry has received growing interest with the implementation of highly conformal radiotherapy treatments. The radiotherapy community faces new challenges with the commissioning of image guided and image gated radiotherapy treatments (IGRT) and deformable image registration software.A new three dimensional anthropomorphically shaped flexible dosimeter, further call...

A semi-supervised machine learning pipeline is reported for the discovery of new Li-ion solid-state electrolytes. The approach experimentally validated with synthesis and characterization a superionic conductor predicted by model.

A dual-frequency 1.55 µm laser for CW low noise microwave, millimeter and sub millimeter wave synthesis is demonstrated, where frequency stabilization is possible on each wavelength independently. The solid state Er:Yb laser output power is 7 mW. The amplitude noise is -150 dBc/Hz at 1 MHz offset frequency. In free running regime, the frequency noise is 3.10(5)/f Hz/sqrt(Hz) (800 Hz on a 1µs ti...

In a typical FAB factory, various types of products are produced around the clock. Complex constraints and re-entrant flows make it difficult for a human scheduler to generate a production schedule based on his/her experience and knowledge. This paper introduces a simulation based FAB scheduler, SeePlan®, which was developed by the authors. A Korea based semi-conductor and LCD maker designated ...

In this paper, a semi-analytical model for the dispersion relation of nanowire lasers is presented. The approach which is based on the multi-conductor transmission line modeling, makes use of the Fourier expansion technique. The cross-section of the nanowire is assumed to be hexagonally-shaped. To determine the accuracy, the model results are compared to the numerical results obtained from FDTD...

Using a conductive atomic force microscope (c-AFM) redox-writing technique, it is shown that it is possible to locally, and reversibly, pattern conducting, and nonconducting features on the surface of a low molecular weight aniline-based organic (semi)-conductor thin film using a commercial c-AFM. It is shown that application of a voltage between the tip and sample causes localized redox reacti...

The compound CeCuAs2 is found to exhibit negative temperature (T) coefficient of electrical resistivity (ρ) under ambient pressure conditions in the entire T-range of investigation (45 mK to 300 K), even in the presence of high magnetic fields. Preliminary tunneling spectroscopic measurements indicate the existence of a psuedo-gap at least at low temperatures, thereby implying that this compoun...

Motivated by the yield optimization problem in semi-conductor manufacturing, we model the wafer to wafer integration problem as a multi-dimensional assignment problem and study it from an approximation point of view. We give approximation algorithms achieving an approximation factor of 3 2 and 4 3 for WWI-3. We show that a special case of yield optimization problem can be solved in polynomial t...
