Implementation of Eigenspace Beamformer combined with Generalized Sidelobe Canceler and Filters for Generating Plane Wave Ultrasound Image (2021)

The use of plane waves allows images with higher frame rates compared to conventional modes. Thus, new processing techniques are studied in order to improve the planewave image quality. The use of the Eigenspace Beamformer technique associated with the Generalized Sidelobe Canceler (EBGSC) reduces the effects of interference and noise, minimizing sidelobes and providing images with higher contrast and resolution compared to the Delay and Sum (DAS) and the Minimum Variance (MV) methods. Filters can also be applied after image processing to reduce speckle signals present in ultrasound images such as the Wiener and Kuan filter. This work presents the implementation of the EBGSC method with Wiener and Kuan filters to improve the processing of plane wave ultrasound images. The EBGSC method combined with Wiener filter (EBGSC-W) showed an improvement in the contrast of 70 % and 57.2 % when compared to the DAS and GSC methods, respectively. The geometric distortion was evaluated using the parameter of the full width at half maximum (FWHM) and the EBGSC-W also obtained a reduction in lateral FWHM by 63 % and 25 % compared to the DAS and GSC methods, respectively, approaching to the actual value of the target size (0.1 mm). The EBGSC method with the Kuan filter (EBGSC-K) showed improvements in the lateral FWHM, however, it worsened the contrast, with loss of information.

A transmission electron microscopy study of microstructural defects in proton implanted silicon (1996)

The microstructure of silicon on defect layer, a new type of silicon-on-insulator material using proton implantation and two-step annealing to obtain a high resistivity buried layer beneath the silicon surface, has been investigated by transmission electron microscopy. Implantation induced a heavily damaged region containing two types of extended defects involving hydrogen: (001) platelets and {111} platelets. During the first step annealing, gas bubbles and {111} precipitates formed. After the second step annealing, {111} precipitates disappeared, while the bubble microstructure still remained and a buried layer consisting of bubbles and dislocations between the bubbles was left. This study shows that the dislocations pinning the bubbles plays an important role in stabilizing the bubbles and in the formation of the defect insulating layer.
Gingival crevicular fluid antibody to oral microorganisms (1984)

A rapid method for collection of static crevicular fluid (SCF) on filter papers is described. Standardization of a Periotron® for volume quantitation of the SCF allowed accurate collection of crevicular fluid samples from periodontal disease patients. A method for elution of SCF was developed and was shown to provide nearly total recovery of antibody activity from the filter papers. Analysis of specific antibody to suspected periodontal pathogens in eight individuals indicated a site‐to‐site variation in antibody levels within the oral cavity. Also, SCF from certain sites exhibited antibody levels that were significantly greater than serum, supporting the concept of specific local antibody synthesis in gingival tissues.
Influence of geometry and safety factor on fatigue damage predictions of a cantilever beam (2019)

The influence of two parameters on fatigue damage predictions of a variably loaded cantilever beam has been examined. The first parameter is the geometry of the cantilever beam and the weld connecting it to a rear panel. Variables of the geometry examined here include the cantilever length, the weld width on the critical cross-section and the angle of the critical cross-section. The second parameter is the safety factor, as set out by the Eurocode 3 standard. An analytical approach has been used to calculate the stresses at the critical cross-section and standard rainflow counting has been used for the extraction of the load cycles from the load history. The results here suggest that a change in the width and angle of the critical cross-section has a non-linear impact on the fatigue damage. The results also show that the angle of the critical cross-section has the biggest influence on the fatigue damage and can cause the weld to withstand fatigue better. The second parameter, the safety factor, is shown to have a significant effect on the fatigue damage calculation, whereby a slight increase in the endurance safety factor can cause the calculated fatigue damage to increase considerably.
A Simple, Efficient, and Economical Method for Recovering DNA from Agarose Gel (2005)

A simple method of recovering DNA from agarose gel that is fast, inexpensive, and friendly both to operators and environment is described. Two rows of wells are made in an agarose gel, and a DNA sample is loaded into the well nearest to the negative pole for separation by electrophoresis. Recovery is accomplished by pipetting the DNA-containing TAE buffer from the well near the positive pole after target DNA fragments have migrated into the well. A recovery rate of up to 94 +/- 2.3% was observed with this method.
Condition based serviceability and reliability assessment of wood pole structures (2002)

New procedures have been developed to assess serviceability of existing wood pole structures. Above or below groundline decay is measured using an instrumented drill and mapped using a customised computer program. Pole structures that contain localised mapped decay are analysed using either deterministic or probabilistic finite element approaches to establish a factor of safety regarding strength and/or probability of survival of the structure. If the poles are involved in an uprating/upgrading/life extension project, additional data is obtained to determine the number of survived years, the acceptable level of reliability, and appropriate inspection intervals. The uniqueness and the benefits of the new methodologies are discussed through examples and a case study.
Relevance of the flavin binding to the stability and folding of engineered cholesterol oxidase containing noncovalently bound FAD (2008)

The flavoprotein cholesterol oxidase (CO) from Brevibacterium sterolicum is a monomeric flavoenzyme containing one molecule of FAD cofactor covalently linked to His69. The elimination of the covalent link following the His69Ala substitution was demonstrated to result in a significant decrease in activity, in the midpoint redox potential of the flavin, and in stability with respect to the wild-type enzyme, but does not modify the overall structure of the enzyme. We used CO as a model system to dissect the changes due to the elimination of the covalent link between the flavin and the protein (by comparing the wild-type and H69A CO holoproteins) with those due to the elimination of the cofactor (by comparing the holo- and apoprotein forms of H69A CO). The apoprotein of H69A CO lacks the characteristic tertiary structure of the holoprotein and displays larger hydrophobic surfaces; its urea-induced unfolding does not occur by a simple two-state mechanism and is largely nonreversible. Minor alterations in the flavin binding region are evident between the native and the refolded proteins, and are likely responsible for the low refolding yield observed. A model for the equilibrium unfolding of H69A CO that also takes into consideration the effects of cofactor binding and dissociation, and thus may be of general significance in terms of the relationships between cofactor uptake and folding in flavoproteins, is presented.
In the Beginning (2010)

I was formally introduced to the noble gases in high school chemistry class, but they were a boring lot and we mostly ignored them. I don’t remember them even being mentioned during college or graduate school. My real affair began in the fall of 1958 at the Brookhaven National Laboratory. I had taken a postdoctoral appointment there to work with one of the foremost nuclear chemists in the country. In 1958 there was Glenn Seaborg in California, Nate Sugarman at the University of Chicago, and Gert Friedlander at Brookhaven. I had finished my PhD work on nuclear reactions at Oak Ridge, and applied to both Chicago and Brookhaven—California was just too far away—with Brookhaven as my clear favorite: it had the world’s biggest atom smasher, the Cosmotron, with 3 Bev of energy, while Chicago had only a few-hundred-Mev machine. So in the spring of 1958 I set off on my first interview trip, hitting Brookhaven first. One of the staff scientists took me around the lab, introducing me to the others. Whenever someone tried to ask me about my research, he shut them off, which I thought strange. And then at eleven o’clock we walked through a door and suddenly there was a room filled with the entire chemistry department looking at me, and my host stopped at the lectern just long enough to say, “Our speaker today is David Fisher, who will tell us about his work on the nuclear reactions induced by nitrogen on sulphur.” Everyone clapped politely, my host sat down, and I stood there like an idiot. I hadn’t had any idea I’d be expected to give a formal lecture to the greatest scientists I had ever met. I hadn’t prepared anything. I quickly considered my options. I could turn and flee through the door I had entered. I could drop dead. I could— There wasn’t anything else. Those were my only options. Or, oh yeah, I could begin to talk.
Resonant soft x-ray scattering from magnetic thin films (2003)

We have applied resonant SAS to characterize the chemical and magnetic heterogeneity of Co-based multilayers as well as CoPtCr-based perpendicular and longitudinal media. Separation of the chemical vs. magnetic heterogeneity is achieved by tuning the x-ray energy to both the Co and Cr edges.
Measurement of the Lund Jet Plane Using Charged Particles in 13 TeV Proton-Proton Collisions with the ATLAS Detector (2020)

The prevalence of hadronic jets at the LHC requires that a deep understanding of jet formation and structure is achieved in order to reach the highest levels of experimental and theoretical precision. There have been many measurements of jet substructure at the LHC and previous colliders, but the targeted observables mix physical effects from various origins. Based on a recent proposal to factorize physical effects, this Letter presents a double-differential cross-section measurement of the Lund jet plane using 139 fb^{-1} of sqrt[s]=13 TeV proton-proton collision data collected with the ATLAS detector using jets with transverse momentum above 675 GeV. The measurement uses charged particles to achieve a fine angular resolution and is corrected for acceptance and detector effects. Several parton shower Monte Carlo models are compared with the data. No single model is found to be in agreement with the measured data across the entire plane.
The Distribution and Foraging Activities of Common Italian and “Hy-Queen” Honey Bees1during Alfalfa Pollination (1978)

The distribution and foraging activities of honey bees ( Apis mellifera L.) were compared for common Italian and Hy-Queen stocks, the latter selected for alfalfa ( Medicago sativa L.) preference and high pollen collection from general sources. The experimental area contained 674 colonies in 27 apiaries. Foraging bees (4000) were collected throughout an alfalfa field (34.0 ha) and tagged with metal discs that were recovered (78.1%) magnetically at hives. Most (81.6%) alfalfa foragers originated from 263 colonies in 12 apiaries at the field. Territorial dominance was evident by bees from the nearest apiaries. Mean foraging distances were 338±56.7 m (common stock) and 237±13.9 m (Hy-queen). Pollen collection from all sources was greater for Hy-Queen (37.9%) than for common stock (30.9%). Stocks were very similar otherwise. Only 1.4% of the alfalfa foragers carried pollen loads, 84.2% of which were from other plant species in the area. Nectar loads of bees collected during foraging were small (mean range = 5.2–9.2 μ liters) and independent of pollen foraging activity. Weak apparent preference for alfalfa by Hy-Queen stock may be caused in part by a genetically reduced foraging distance.
Characterization of Acoustic Emission Signals from Mode I Crack (1991)

Separation of crack growth signals is of fundamental importance for detecting, locating, and determining the significance of an internal flaw using acoustic emission techniques. The methodology used to determine the acoustic emission signal in this paper incorporates a source model that is an actual crack propagation and arrest event. This source model includes the effects of the following physical parameters: location of the crack, crack orientation, crack tip velocity, duration of crack propagation, and mode of fracture. The integral equation method is used to examine a semi‐infinite crack in an infinite, linear elastic body loaded under the conditions of plane strain. The dynamic mode I stress caused by a crack propagating with a prescribed velocity is determined, and then the displacements at any point are calculated. These time‐dependent displacements are the analytical form of the acoustic emission waveforms. Numerical results examine the effect of crack tip velocity, duration of propagation, and distance from the crack source to the point of observation on the calculated acoustic emission signals.
The High Pressure High Shear Stress Rheology of Liquid Lubricants (1992)

A limiting shear stress model of liquid lubricant shear rheology is offered which accurately represents all available primary data. The model is of the nonlinear Maxwell type with shear modulus taken into the time derivative and broadening of the viscous-plastic transition with pressure. Property relations for viscosity, limiting stress and shear modulus are refined for a polyphenyl ether in particular. The model, with simplifying assumptions, is compared with disk machine results. This model, with change of yield criterion, may be applicable to some shear thinning liquids at low pressure. Limiting shear stress varies with pressure in the same manner as the ultimate shear strength of solid polymers.

Generation of a radially polarized laser beam by use of the birefringence of a c-cut Nd:YVO4 crystal (2006)

We demonstrated the generation of a radially polarized laser beam from an extremely simple laser resonator including a c-cut Nd:YVO4 crystal as a laser medium. The oscillation in the radial polarization was based on the optical path difference between an extraordinary ray and an ordinary ray induced by the birefringence of the crystal. By simply adjusting the distance between two cavity mirrors, only the extraordinary ray became stable for the oscillation, resulting in the generation of a radially polarized beam. The beam was very stable even at low power output and is expected to be a promising radially polarized laser source because of its excellent simplicity.
Autocapture Enhancements: Unipolar and Bipolar Lead Compatibility and Bipolar Pacing Capability on Bipolar Leads (2003)

Beat-by-beat Autocapture maximizes device longevity by minimizing stimulus amplitude while assuring patient safety. Currently, Autocapture permits use of only bipolar leads. The authors have devised a detection method that operates with unipolar and bipolar leads and covers all pacing and sensing combinations (but bipolar pace and sense simultaneously). This new detection method for unipolar sensing uses the integral of the negative portion of the unipolar evoked response as a robust capture detection feature. When using bipolar leads, the method provides the flexibility of bipolar or unipolar pacing. In this study, unipolar ventricular intracardiac electrograms (EGMs) were recorded in 71 patients, 73.7 +/- 9.9 years of age; 9 with high polarization, 62 with low polarization. High polarization had polished platinum or activated carbon electrodes. Low polarization had TiN, platinized platinum, or IrOx electrodes. The intracardiac EGMs were recorded 544 +/- 796 days after implant. The pacemakers performed an automatic capture threshold test while the intracardiac EGM signals were recorded in a programmer. These digitized signals were saved for off-line analysis. The unipolar evoked response was calculated at up to six (depending on capture threshold) pacing voltages and the polarization integral at 4.5 V and at loss of capture. An automatic calibration algorithm determined if the signal-to-noise ratio was adequate for Autocapture operation. Autocapture was possible with 60 of 62 of the low polarizations, and with 6 of 9 of the high polarizations. The average values form the data collected were: average unipolar evoked response--4.1 +/- 2.1 mV, average peak negative voltage--10.0 +/- 3.7 mV, average polarization 0.3 +/- 0.34 mV, and average signal-to-noise ratio (unipolar evoked response/ polarization) 38 +/- 71. In all cases the algorithm correctly determined the appropriateness of using Autocapture with the electrodes tested and the unipolar evoked response threshold to be used.

Identification of a novel temperature sensitive promoter in cho cells (2011)

This novel CHO promoter permits conditionally high-level gene expression. Upon a shift to 33°C, a two to three-fold increase of basal productivity (already higher than SV40 promoter) is achieved. This property is of particular advantage for a process with reduced expression during initial cell growth followed by the production phase at low temperature with a boost in expression. Additionally, production of toxic proteins becomes feasible, since cell metabolism and gene expression do not directly interfere. The CHO S100a6 promoter can be characterized as cold-shock responsive with the potential for improving process performance of mammalian expression systems.
Immunogenicity of amyloid. (1971)

Human amyloid appears to contain two immunogenic components, the P (plasma) component and the F (fibril) component. Antisera to P component react with both autologous and homologous antigens by immunodiffusion and fluorescent antibody techniques; antisera to F component react with autologous antigens by immunodiffusion and fluorescent antibody techniques, but react with homologous antigens only by the fluorescent antibody method. Antisera to both P component and F component fail to react with non-amyloid human tissues as well as amyloid deposits in guinea-pig tissues. These results point to heterogeneity in the antigenic determinants of human amyloid and possibly greater inter-species heterogeneity of amyloid.
