Pretilt study of double‐layer alignment film (DLAF) (2008)

A novel double‐layer alignment film (DLAF) was developed to obtain greater control of the alignment characteristics of the liquid crystal director. The DLAF consists of a thin fluorinated polymer layer on the top of a rubbed non‐fluorinated, non‐branched polyimide layer (PI 2555). Two types of fluorinated polymer with different chemical structures and wetting behaviour on PI 2555 were chosen, to provide either continuous or discontinuous top layers. The continuous top layer DLAF (DLAF‐1) exhibits an abrupt pretilt transition from planar to homeotropic as the top layer thickness increases. The discontinuous top layer DLAF (DLAF‐2) exhibits a gradual transition where the pretilt correlates with the coverage of fluorinated top layer. These two types of transitions fit with de Gennes' local Frederick's transition and Kwok's inhomogeneous alignment theories, respectively. The abrupt pretilt transition system may be promising for chemical/biosensor applications, whereas the gradual transition system is suitable for pretilt control in LCD devices.
X-ray photoelectron spectroscopy for resistance-capacitance measurements of surface structures (2005)

In x-ray photoemission measurements, differential charging causes the measured binding energy difference between the Si 2p of the oxide and the silicon substrate to vary nonlinearly as a function of the applied external dc voltage stress, which controls the low-energy electrons going into and out of the sample. This nonlinear variation is similar to the system where a gold metal strip is connected to the same voltage stress through an external 10 Mohm series resistor and determined again by x-ray photoelectron spectroscopy (XPS). We utilize this functional resemblance to determine the resistance of the 4 nm SiO2 layer on a silicon substrate as 8 Mohm. In addition, by performing time-dependent XPS measurements (achieved by pulsing the voltage stress), we determine the time constant for charging∕discharging of the same system as 2.0 s. Using an equivalent circuit, consisting of a gold metal strip connected through a 10 Mohm series resistor and a 56 nF parallel capacitor, and performing time-dependent XPS measurements, we also determine the time constant as 0.50 s in agreement with the expected value (0.56 s). Using this time constant and the resistance (8.0 Mohm), we can determined the capacitance of the 4 nm SiO2 layer as 250 nF in excellent agreement with the calculated value. Hence, by application of external dc and pulsed voltage stresses, an x-ray photoelectron spectrometer is turned into a tool for extracting electrical parameters of surface structures in a noncontact fashion.
Image fusion technique for head-neck CT and SPECT image registration (2002)

A SPECT-CT image fusion technique is developed to provide more precise anatomical location and extension of basal skull involvement of NPC detected by Tc-99m MDP bone scan, and a better treatment planning is achieved. In this technique, both SPECT images and head-neck CT images are appropriately separated to two sections, head slices of the images and neck slices of the images. A multimodality image registration procedure is used to individually align the head/neck section of SPECT images to the head/neck section of CT images respectively. The procedure requires: generation of simulated SPECT images using the bone component in CT images, and then aligning the measured SPECT images to the simulated ones that are based on CT images. In order to benefit from the advantages of CT and SPECT images, the two aligned images have fused together. The fused images allow users to precisely delineate the interests of region (ROIs) on SPECT images shown to have involvement of NPC. Moreover, the fused images are also useful for accurate therapeutic planning in radiation oncology and for consistent evaluation of the results between the pre- and post-treatments.
Microfluidic pressure sensing using trapped air compression (2007)

We have developed a microfluidic method for measuring the fluid pressure head experienced at any location inside a microchannel. The principal component is a microfabricated sealed chamber with a single inlet and no exit; the entrance to the single inlet is positioned at the location where pressure is to be measured. The pressure measurement is then based on monitoring the movement of a liquid-air interface as it compresses air trapped inside the microfabricated sealed chamber and calculating the pressure using the ideal gas law. The method has been used to measure the pressure of the air stream and continuous liquid flow inside microfluidic channels (d approximately 50 microm). Further, a pressure drop has also been measured using multiple microfabricated sealed chambers. For air pressure, a resolution of 700 Pa within a full-scale range of 700-100 kPa was obtained. For liquids, pressure drops as low as 70 Pa were obtained in an operating range from 70 Pa to 10 kPa. Since the method primarily uses a microfluidic sealed chamber, it does not require additional fabrication steps and may easily be incorporated in several lab-on-a-chip fluidic applications for laminar as well as turbulent flow conditions.
Linear Precoding Versus Linear Multiuser Detection in Downlink TDD-CDMA Systems (2007)

In this paper, we compare two classes of linear interference suppression techniques for downlink TDD-CDMA systems, namely, linear multiuser detection methods (receiver processing) and linear precoding methods (transmitter processing). For the linear precoding schemes, we assume that the channel state information (CSI) is available only at the transmitter but not at the receiver (i.e., ultra simple receivers). We propose several precoding techniques and the corresponding power control algorithms. The performance metric used in the comparisons is the total power required at the transmitter to achieve a target SINR at the receiver. Our results reveal that in general multiuser detection and precoding offer similar performance; but in certain scenarios (e.g, low BER requirements or use of random spreading sequences), precoding can bring a substantial performance improvement. These results motivate the use of precoding techniques to reduce the complexity of the system and the mobile terminals (only a matched-filter to the own spreading sequence is required without CSI). Moreover, it is shown that the proposed chip-wise linear MMSE precoding method is optimal in the sense that it requires the minimum total transmitted power to meet a certain receiver SINR performance.

A comparative analysis of regional correlation, dynamic time warping, and skeletal tree matching for signature verification (1990)

A report is presented on a comparative study of three different signal matching algorithms in the context of signature verification: regional correlation, dynamic time warping, and skeletal tree matching. The algorithm performances are compared in a single experimental protocol over the same database. Algorithm performance is analyzed in terms of verification error rates, execution time, and number and sensitivity of algorithm parameters. Three different script types (normal signatures, handwritten passwords, and initials) and three different signal representation spaces (position, velocity, and acceleration) are considered. Verification errors show that no algorithm consistently outperforms the others in all circumstances.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

"Partially rounded" small-order approximations for accurate, hardware-oriented, table-based methods (2004)

We aim at evaluating elementary and special functions using small tables and small, rectangular, multipliers. To do that, we show how accurate polynomial approximations whose order-1 coefficients are small in size (a few bits only) can be computed. We compare the obtained results with similar work in the recent literature.
Finite element modeling of retinal prosthesis mechanics (2009)

Epiretinal prostheses used to treat degenerative retina diseases apply stimulus via an electrode array fixed to the ganglion cell side of the retina. Mechanical pressure applied by these arrays to the retina, both during initial insertion and throughout chronic use, could cause sufficient retinal damage to reduce the device's effectiveness. In order to understand and minimize potential mechanical damage, we have used finite element analysis to model mechanical interactions between an electrode array and the retina in both acute and chronic loading configurations. Modeling indicates that an acute tacking force distributes stress primarily underneath the tack site and heel edge of the array, while more moderate chronic stresses are distributed more evenly underneath the array. Retinal damage in a canine model chronically implanted with a similar array occurred in correlating locations, and model predictions correlate well with benchtop eyewall compression tests. This model provides retinal prosthesis researchers with a tool to optimize the mechanical electrode array design, but the techniques used here represent a unique effort to combine a modifiable device and soft biological tissues in the same model and those techniques could be extended to other devices that come into mechanical contact with soft neural tissues.
DOA estimation of coherent waves for 77GHZ automotive radar with three receiving antennas (2009)

This paper proposes a novel scheme suitable for mm-wave automotive radars to estimate the direction-of-arrivals (DOAs) of coherent waves with only three receiving antennas. Reflected waves completely correlated from two targets can be resolved with calibrated 3-channel array antenna by using only one snapshot data. The resolution capability can be further improved with the use of multiple snapshot data. A 77GHz prototype radar mounted on a vehicle successfully measured the directions of two stationary targets in real time computation.
Improved fusion partners transfected with DNA fragment encoding IL-11 on generation of human B lymphocyte hybridomas (1999)

IL-11, a less identified cytokine, possesses some overlapping functions with IL-6 that are able to facilitate the growth and antibody secretion of B lymphocyte hybridomas. In this report, a DNA fragment encoding human IL-11 was transduced into fusion partners (mouse myelomas Ag8.653 and SP2/0, and human lymphoblastoid cell line HF2) mediated by lipofection. The transfected cells selected with G418 secreted IL-11 constitutively over the range of 32.4 +/- 10.5 units/ml to 76.6 +/- 18.4 units/ml, which could be inhibited by an IL-11 neutralizing MAb up to 80%. The fusion frequency of PBMC doubled, while that of LCLs displayed a 2.4- or 3.3-fold increase, when fused with the transfected fusion partners, respectively. The derived hybridomas from IL-11 secreting fusion partner secreted 3 or 4 times as many immunoglobulins as that from its ancestor. Our data indicate that IL-11 gene transfected fusion partners are improved cell lines for generation of human B lymphocyte hybridomas, and IL-11 may contribute to the increased fusion frequency and antibody secretion of B lymphocyte hybridomas.
Stimulation of Cellular Thymidine Kinases by Human Cytomegalovirus (1977)

Thymidine kinase (TK) activity in WI-38 and MRC-5 human fibroblasts was analyzed by discontinuous polyacrylamide gel electrophoresis (disc-PAGE) and discontinuous glycerol gradient electrophoresis (disc-GEP) after subculture or human cytomegalovirus (HCMV) infection. Two peaks of TK activity with different relative fraction-of-migration ( R f ) values were resolved by disc-PAGE or disc-GEP in extracts from log-phase and infected cells. Growing WI-38 cells expressed a slowly migrating ( R f = 0.14 PAGE, R f = 0.4 GEP) peak of TK activity, which was partially inhibited by 1.0 mM dCTP, but which retained little activity at pH 4.5. Growing MRC cells also displayed a slowly migrating peak ( R f = 0.10 PAGE) with similar properties. Both cell types expressed a faster-migrating TK activity ( R f = 0.45 PAGE, R f = 0.7 GEP) in the growing and resting state that was strongly inhibited by 1 mM dCTP but retained 50% activity at pH 4.5. When either cell type was infected with HCMV, there was a rapid and high-level stimulation of the slowly migrating form of TK and a slight stimulation of the faster-migrating form. Two strains of HCMV (AD169 and Town) failed to produce an electrophoretically distinct virus TK in either cell type after infection. TK enzymes were partially purified by disc-GEP from extracts of log-phase WI-38 or AD169-infected WI-38 cells. Characterization of these enzymes with respect to phosphate donor specificity, pH optima, thermostability, and salt inhibition showed the HCMV-stimulated TKs to be of cellular origin.
Pyrolytic Gaseous Hydrocarbon Generation and the Kinetics of Carbon Isotope Fractionation in Representative Model Compounds With Different Chemical Structures (2019)

Abstract Five model compounds with representative chemical structures were selected for use in simulation experiments of pyrolytic gas production. The gas production and isotopic fractionation characteristics were observed and analyzed. Then, the factors affecting carbon isotope fractionation during natural gas generation were discussed, and a fractionation model was established and calibrated. We concluded that the final hydrocarbon gas (C 1–5 ) yield of octadecane, octadecylamine, octadecanoic acid, decahydronaphthalene, and 9‐phenylanthracene decreased in turn with the effective hydrogen content. Compared with linear alkanes or alkyl compounds, cycloalkanes have higher thermal stability and generate gas later. The variation in the carbon isotopic composition of natural gas is primarily controlled by the following three factors: (a) the thermal evolution of organic matter results in a gradually heavier isotopic composition for the main gas production stage. (b) Gas inherits the isotopic composition of its parent material, and this effect is evident when the chemical structure and gas generation mechanism between parent materials are similar. (c) The structure of organic matter determines the reaction mechanism of gas generation, which has a significant influence on the range and trend of carbon isotope fractionation in the process of methane generation. An improved chemical kinetic model can accurately characterize carbon isotope fractionation during gas generation.
Multiple-beam laser velocimeter: analysis and applications (1980)

In the multiple-beam laser velocimeter a large number of beams intersect to form sharp intense spots well separated by dark areas. The correlation function for particles moving through such an intensity distribution is calculated from first principles and verified experimentally. Interpretations of systems with a distribution of particle velocities can be made with less ambiguity using the multiple-beam laser velocimeter rather than the conventional two-beam model. The technique is demonstrated by measuring the velocity distribution of particles in a fast fluidized bed.
Test pattern and test configuration generation methodology for the logic of RAM-based FPGA (2002)

The test of the Configurable Logic Blocks of RAM based FPGAs under a Stuck-At fault model has been studied. The high cost of changing the configuration, by reprogramming the FPGA during testing, forces a strategy to reduce the number of different configurations used for testing purposes. After finding the optimal solutions for the elementary structures of the Logic block, Multiplexers and Look-Up Tables, the problem of testing interconnected elementary structures is addressed. The method is illustrated using an elementary structure and then applied to a popular FPGA (XILINX 3000 family) where a reduced set of configurations (5) and their corresponding test sequences is found to cover all (100%) the Configurable Logic Block faults modelled.
A Hexylchloride-Based Catch-and-Release System for Chemical Proteomic Applications (2013)

Bioorthogonal ligation methods that allow the selective conjugation of fluorophores or biotin to proteins and small molecule probes that contain inert chemical handles are an important component of many chemical proteomic strategies. Here, we present a new catch-and-release enrichment strategy that utilizes a hexylchloride group as a bioorthogonal chemical handle. Proteins and small molecules that contain a hexylchloride tag can be efficiently captured by an immobilized version of the self-labeling protein HaloTag. Furthermore, by using a HaloTag fusion protein that contains a protease cleavage site, captured proteins can be selectively eluted under mild conditions. We demonstrate the utility of the hexylchloride-based catch-and-release strategy by enriching protein kinases that are covalently and noncovalently bound to ATP-binding site-directed probes from mammalian cell lysates. Our catch-and-release system creates new possibilities for profiling enzyme families and for the identification of the cellular targets of bioactive small molecules.

Development and Implementation of a Pharmacy Directed Community Health Education and Screening Program (2005)

Purpose A major obstacle to successfully offering health care education programs is a lack of access to large numbers of people. To capture a large audience we proposed a pharmacy directed community health education and screening program using the hockey games at the University of Utah as the venue to educate a significant population. The objectives of this project were to evaluate the patrons’ perception of health care screening/education sessions offered at hockey games and to discover the number of patrons participating in the programs. Methods A variety of health care screening/education programs were offered at 12 hockey games on the University of Utah campus. Health care professionals were present to provide information, conduct screenings, and answer questions. All patrons who participated were asked to complete an anonymous survey to determine if the health sessions in this setting were beneficial. Results A total of 801 useable surveys were received from patrons who were screened and/or educated. Overall, the health care screening/education sessions were well perceived with 92% of the patrons rating the overall value of the sessions as “very good” or “excellent.” Patrons who were identified as being at risk for certain disease states were encouraged to follow-up with a physician. Conclusion The health care education/screening sessions provided at the University of Utah hockey games were successful based on the survey results and the number of patrons who participated. This program also demonstrated pharmacists can play a very effective role in designing and delivering health education to large numbers of patients.
