Optical imaging through turbid media with a degenerate four wave mixing correlation time gate (1994)

A novel method for detection of ballistic light and rejection of unwanted diffusive light to image structures inside highly scattering media is demonstrated. Degenerate four wave mixing (DFWM) of a doubled YAG laser in Rhodamine 6G is used to provide an ultrafast correlation time gate to discriminate against light that has undergone multiple scattering and therefore lost memory of the structures inside the scattering medium. We present preliminary results that determine the nature of the DFWM grating, confirm the coherence time of the laser, prove the phase-conjugate nature of the signal beam, and determine the dependence of the signal (reflectivity) on dye concentration and laser intensity. Finally, we have obtained images of a test cross-hair pattern through highly turbid suspensions of whole milk in water that are opaque to the naked eye. These imaging experiments demonstrate the utility of DFWM for imagingthrough turbid media. Based on our results, the use of DFWM as an ultrafast time gate for the detectionof ballistic light in optical mammography appears to hold great promise for improving the current state of the art.

Pilot field trial of a recombinant <i>Taenia ovis</i> vaccine in lambs exposed to natural infection (1996)

Previous trials of an experimental Taenia ovis vaccine using the recombinant antigen GST--45W(B/X) established that it was possible to achieve >90% protection against a single artificial challenge of T. ovis eggs. This trial was undertaken to assess vaccine efficacy against artificial challenge and natural infection acquired by lambs grazing contaminated pasture. Two hundred Romney lambs were vaccinated at 6 and 12 weeks of age. One hundred control lambs were not vaccinated but were allowed to run with the vaccinated mob. At 15 weeks of age, 10 controls and 18 vaccinated lambs were artificially challenged with 2000 T. ovis eggs. The remaining control and vaccinated lambs were allowed to graze contaminated pasture for 3 weeks and were then moved to clean pasture for 5 months. The artificially challenged lambs plus 24 of the field-infected lambs were slaughtered and the carcasses dissected to obtain cyst counts. The remaining field-infected lambs were slaughtered at a commercial processing plant and the carcasses examined by conventional meat inspection. The results showed that the vaccine provided a high level of protection against artificial challenge (92%) and natural infection (98%) when assessed by carcass dissection. The data from commercial meat inspection showed that vaccination provided 89% efficacy against downgrading or condemnation compared to non-vaccinated control lambs. The average difference in carcass values between vaccinated and non-vaccinated groups was 4.36 dollars, representing a 35% loss in value due to T.ovis infection in non-vaccinated lambs.
Translational and rotational jitter invariant incremental principal component pursuit for video background modeling (2015)

While Principal Component Pursuit (PCP) is currently considered to be the state of the art method for video background modeling, it suffers from a number of limitations, including a high computational cost, a batch operating mode, and sensitivity to camera jitter. In this paper we propose a novel fully incremental PCP algorithm for video background modeling that is robust to translational and rotational jitter. It processes one frame at a time, obtaining similar results to standard batch PCP algorithms, while being able to deal with translational and rotational jitter. It also has extremely low memory footprint, and a computational complexity that allows almost real-time processing.
Creating Texture Exemplars from Unconstrained Images (2013)

Texture is an essential feature in modeling the appearance of objects and is instrumental in making virtual objects appear interesting and/or realistic. Unfortunately, obtaining textures is a labor intensive task requiring parameter tuning for procedural methods or careful photography and post-processing for natural images. Many texture synthesis techniques have been developed to generate textures of arbitrary spatial extent, but these techniques require the user to first produce an exemplar consisting solely of the desired texture. We present a fast method using diffusion manifolds to locate textures in unconstrained photographs, and extract exemplar tiles. The method requires the user to only specify a single point within the image containing the desired texture and the scale of the desired texture. The user may tune the result using simple interactions. The method is non-local, in the sense that the desired texture does not have to appear in a single contiguous region in the source image. This document is a summary of our work and system. A full account is available online.
The Montgomery modular inverse-revisited (2000)

We modify an algorithm given by Kaliski to compute the Montgomery inverse of an integer modulo a prime number. We also give a new definition of the Montgomery inverse, and introduce efficient algorithms for computing the classical modular inverse, the Kaliski-Montgomery inverse, and the new Montgomery inverse. The proposed algorithms are suitable for software implementations on general-purpose microprocessors.

Circuit simplicity allows for easy monolithic construction.
LEAD CHROMATES: THE STATE OF THE ART IN 1988 (1988)

Lead chromates are known to be the most versatile of all coloured inorganic pigments. Therefore it is worthwhile to review the state of the art of this class of pigments. The chemistry of chrome yellows and molybdate oranges is discussed in connection with the factors which determine shade and performance. The properties are related to the performance of other inorganic pigments as well as organic pigments. Although lead chromates have been available for about 90 years, it still is possible to achieve significant improvements. Consequently the latest developments in lead chromate pigment chemistry are discussed.

The method aims to distribute all energy in the simultaneous shot records by reconstructing the individual shot records at their respective locations. The method is applied to a simulated simultaneous long offset data set, where two sources are used to acquire long offsets with conventional cables. In the second example, the performance is investigated on a data set from Western Australia, where two sources where located within close proximity, with only a small cross line distance between them. Results demonstrate that the individual sources can be separated satisfactory for both simultaneous source configurations.

Cooperativity in Virus Neutralization by Human Monoclonal Antibodies to Two Adjacent Regions Located at the Amino Terminus of Hepatitis C Virus E2 Glycoprotein (2012)

A challenge for hepatitis C virus (HCV) vaccine development is defining conserved epitopes that induce protective antibodies against this highly diverse virus. An envelope glycoprotein (E2) segment located at amino acids (aa) 412 to 423 contains highly conserved neutralizing epitopes. While polyclonal antibodies to aa 412 to 423 from HCV-infected individuals confirmed broad neutralization, conflicting findings have been reported on polyclonal antibodies to an adjacent region, aa 434 to 446, that may or may not interfere with neutralization by antibodies to aa 412 to 423. To define the interplay between these antibodies, we isolated human monoclonal antibodies (HMAbs) to aa 412 to 423, designated HC33-related HMAbs (HC33 HMAbs), and characterized their interactions with other HMAbs to aa 434 to 446. A subset of the HC33 HMAbs neutralized genotype 1 to 6 infectious cell culture-derived HCV virions (HCVcc) with various activities. Although nonneutralizing HC33 HMAbs were isolated, they had lower binding affinities than neutralizing HC33 HMAbs. These antibodies could be converted to neutralizing antibodies by affinity maturation. Unidirectional competition for binding to E2 was observed between HC33 HMAbs and HMAbs to aa 434 to 446. When HMAbs to aa 434 to 446, which mediated neutralization, were combined with neutralizing HC33 HMAbs, biphasic patterns in neutralization were observed. A modest degree of antagonism was observed at lower concentrations, and a modest degree of synergism was observed at higher concentrations. However, the overall effect was additive neutralization. A similar pattern was observed when these antibodies were combined to block E2 binding to the HCV coreceptor, CD81. These findings demonstrate that both of these E2 regions participate in epitopes mediating virus neutralization and that the antibodies to aa 412 to 423 and aa 434 to 446 do not hinder their respective virus-neutralizing activities.
Study on Reduction Methods of Moiré Noise in Image Acquisition of Periodic Gray‐Scale Pattern (2002)

Abstract Creating valid digital images for display surfaces is vital for the quantification of display quality (defects, spots) for display devices. However, when imaging a spatially discrete display surface using individual acquisition elements, an acquisition moiré appears in the acquisition image. In this paper the authors quantify the display acquisition image, then clarify how to find the acquisition moiré from the dimensions of the display system and acquisition target using computations. Based on these results, the authors formulate a method for determining a pixel shift which inverts the moiré phase in a pixel‐shifted image. They then propose a method to compute the average in pixel units of gradations between a reference image and a pixel‐shifted image given by a reference image and a pixel‐shifted image created using the above method. Finally, they verify the effects of reducing the acquisition moiré using simulations. © 2001 Scripta Technica, Syst Comp Jpn, 33(1): 27–37, 2002
Effect of Dronabinol on Nutritional Status in HIV Infection (1993)

OBJECTIVE: To examine the effect of dronabinol (delta-9-tetrahydrocannabinol) on appetite and nutritional status in patients with symptomatic HIV infection and weight loss. DESIGN: Double-blind, randomized, placebo-controlled, crossover trial with two five-week treatment periods separated by a two-week washout period. Patients received dronabinol 5 mg twice daily before meals or placebo. SETTING: A university-based HIV/AIDS clinic and a large infectious disease private practice largely devoted to care of patients with HIV. PARTICIPANTS: Twelve HIV-infected patients who had had at least a 2.25-kg weight loss participated in the study. Five patients completed the protocol, and seven withdrew (two because of drug intolerance, two because of disease progression, two because of noncompliance, and one because of experimental antiretroviral therapy). MAIN OUTCOME MEASURES: Main outcome measures included caloric intake, weight, percent body fat, serum prealbumin, and symptom distress. RESULTS: During dronabinol treatment, subjects experienced increased percent body fat (one percent, p=0.04); decreased symptom distress (p=0.04); and trends toward weight gain (0.5 kg, p=0.13), increased prealbumin (29.0 mg/L, p=0.11), and improved appetite score (p=0.14). CONCLUSIONS: In a selected group of HIV-infected patients with weight loss, short-term treatment with dronabinol may result in improvement in nutritional status and symptom distress.
Development of a Curable Conductive Copper Paste in Air (2015)

In this study, we are going to report on development of conductive copper paste curable in air. The copper paste was prepared by a simple and facile method using copper powder with resin and additives such as tri-ethanolamine (TEA) and liquid fatty acid. The prepared copper paste was screen-printed on an alumina substrate, then cured at 210°C for 10 min in air to obtain cured copper product. The resistivity of the product with additives was less than 6.0 × 10-5 Ω∙cm. Without the additives, the resistivity was 7.1 × 10-4 Ω∙cm, it was higher than the case of with additives. These results indicate that TEA and liquid fatty acid interact with each other in the copper paste, and then the resistivity is decreased. Furthermore, the copper pastes using a liquid fatty acid and TEA had longer "pot life" than that of the other copper pastes.
Shugoshin protects cohesin complexes at centromeres - Discussion (2005)

The different regulation of sister chromatid cohesion at centromeres and along chromosome arms is obvious during meiosis, because centromeric cohesion, but not arm cohesion, persists throughout anaphase of the first division. A protein required to protect centromeric cohesin Rec8 from separase cleavage has been identified and named shugoshin (or Sgo1) after shugoshin ("guardian spirit" in Japanese). It has become apparent that shugoshin shows marginal homology with Drosophila Mei-S332 and several uncharacterized proteins in other eukaryotic organisms. Because Mei-S332 is a protein previously shown to be required for centromeric cohesion in meiosis, it is now established that shugoshin represents a conserved protein family defined as a centromeric protector of Rec8 cohesin complexes in meiosis. The regional difference of sister chromatid cohesion is also observed during mitosis in vertebrates; the cohesion is much more robust at the centromere at metaphase, where it antagonizes the pulling force of spindle microtubules that attach the kinetochores from opposite poles. The human shugoshin homologue (hSgo1) is required to protect the centromeric localization of the mitotic cohesin, Scc1, until metaphase. Bub1 plays a crucial role in the localization of shugoshin to centromeres in both fission yeast and humans.
High-speed electrical backplane transmission using duobinary signaling (2005)

High-speed electrical data transmission through low-cost backplanes is a particularly challenging problem. We present for the first time a very effective approach that uses the concept of duobinary signaling to accomplish this task. Using a finite-impulse-response filter, we are able to compensate for the phase and amplitude response of the backplane such that the resulting frequency response of the channel is that of an ideal duobinary filter. At the output of the backplane, we use an innovative pseudodigital circuit to convert the electrical duobinary to binary. For 10-Gb/s data transmission, we demonstrate a bit error rate <10/sup -13/ through electrical backplane traces up to 34 in in length on FR4. A full discussion of the concept, system architecture, and measured results are presented. Analysis is presented that compares and contrasts this approach to PAM-4 and standard nonreturn-to-zero signaling.
Attribution of Conversion Events to Multi-channel Media (2010)

This paper presents a practical method for measuring the impact of multiple marketing events on sales, including marketing events that are not traditionally trackable. The technique infers which of several competing media events are likely to have caused a given conversion. We test the method using hold-out sets, and also a live media experiment in which we test whether the method can accurately predict television-generated web conversions.
Aqueous two-phase microdroplets with reversible phase transitions (2013)

Aqueous two-phase systems contained within microdroplets enable a bottom-up approach to mimicking the dynamic microcompartmentation of biomaterial that naturally occurs within the cytoplasm of cells. Here, we demonstrate the generation of femtolitre aqueous two-phase droplets within a microfluidic oil channel. Gated pressure pulses were used to generate individual, stationary two-phase microdroplets with a well-defined time zero for carrying out controlled and sequential phase transformations over time. Reversible phase transitions between single-phase, two-phase, and core-shell microbead states were obtained via evaporation-induced dehydration and water rehydration. In contrast to other microfluidic aqueous two-phase droplets, which require continuous flows and high-frequency droplet formation, our system enables the controlled isolation and reversible transformation of a single microdroplet and is expected to be useful for future studies in dynamic microcompartmentation and affinity partitioning.
Lateral Electrical Surface Stimulation as an Alternative To Bracing in the Treatment of Idiopathic Scoliosis (1984)

The purpose of this article is twofold. The first is to describe the management by physical therapists of patients using lateral electrical surface stimulation (LESS) for the treatment of progressive idiopathic scoliosis. In this treatment, electrodes are placed on the convex side of the curve in the region of the posterior to midaxillary line to produce a corrective force. Stimulation is applied nightly as the patient sleeps. Treatment is monitored by regular checkups and is stopped at achievement of skeletal maturity. No other treatment or exercises are necessary. The second purpose is to present the results of a questionnaire given to patients who had used LESS for at least six months. Fifty-seven patients and their parents responded to questions on scoliosis, acceptance of LESS treatment, and comparison of LESS treatment with previous brace treatment, if appropriate. Results indicated that many of the brace-associated problems were eliminated, and patient acceptance was high.
Low-cost optical microstructures fabricated by imprinting porous silicon (2010)

We present a direct-to-device method for stamping porous silicon to produce optical microstructures. The stamping technique utilizes a reusable silicon stamp fabricated by standard lithographic methods. Large area (9mm<sup>2</sup>) stamps are applied to single layer thin films of porous silicon with a force on the order of 1kN. The process affords precise control over both lateral and vertical dimensions of patterning while maintaining large area uniformity. We demonstrate tunable imprint depths in the 10nm-120nm range as well as lateral feature sizes down to 0.25μm. Imprinted structures are characterized by scanning electron microscopy (SEM), atomic force microscopy (AFM), and optical diffraction experiments. By utilizing reusable stamps and a straightforward technique, the overall process can be performed at low-cost and high throughput. This enables a wide variety of optical microstructures to be readily fabricated. As an example, we present a porous diffraction grating and demonstrate proof-of-concept sensing capabilities, for exposure to water vapor as well as small molecules (3-aminopropyltriethoxysilane). Additional device structures enabled by this fabrication process are also discussed. The stamping process is expected to be applicable to other porous materials such as porous titania, porous alumina, and porous silica.
Verification of Object-Oriented Programs with Invariants. (2004)

An object invariant defines what it means for an object's data to be in a consistent state. Object invariants are central to the design and correctness of objectoriented programs. This paper defines a programming methodology for using object invariants. The methodology, which enriches a program's state space to express when each object invariant holds, deals with owned object components, ownership transfer, and subclassing, and is expressive enough to allow many interesting object-oriented programs to be specified and verified. Lending itself to sound modular verification, the methodology also provides a solution to the problem of determining what state a method is allowed to modify.
Real time color Doppler optical coherence tomography using a novel autocorrelation technique (2003)

Summary form only given. Color Doppler optical coherence tomography (CDOCT) is a functional extension of optical coherence tomography (OCT) which can image flow in turbid media with micronscale spatial resolution. In CDOCT, flow velocity information is encoded in the Doppler shift of the probe light by moving scatterers in the sample. The scanning optical delay line in the reference arm of a CDOCT interferometer imposes a Doppler shift on the reference light, therefore, the Doppler information indicating flow in the sample can be detected as a frequency offset from the center frequency of the detector response signal. In previous implementations of CDOCT, this information has been extracted offline by digital signal processing of the acquired image data. This type of processing is computationally intensive and may not be suitable for real-time blood flow imaging.
Identification of a 17β‐Hydroxysteroid Dehydrogenase Type 10 Steroidal Inhibitor: A Tool to Investigate the Role of Type 10 in Alzheimer’s Disease and Prostate Cancer (2012)

Ten out of ten! Androsterone derivatives inhibit 17β-hydroxysteroid dehydrogenase type 10 (17β-HSD10), a versatile mitochondrial NAD+-dependent enzyme with potential roles in both Alzheimer's disease and prostate cancer. These androsterone derivatives could be useful tool compounds to help elucidate the role of 17β-HSD10 in these important diseases.
