STUDIES OF ISOZYME PATTERNS IN NULLISOMIC-TETRASOMIC COMBINATIONS OF HEXAPLOID WHEAT (1969)

Thirty-eight wheat strains, each nullisomic for one chromosome and tetrasomic for a homoeologous (related) one, were analyzed electrophoretically for 12 different enzymes, and a gene (or genes) for alkaline phosphatase was localized to chromosomes 4B and 4D. The other 11 enzymes showed no significant electrophoretic variation. The fact that the only mutants observed affect the same enzyme favors the concept that rigorous selection operates in the polyploids both to preserve certain types of variants and to eliminate others.

The Westwood Experience: Connecting story to locations via Mixed Reality (2010)

The Westwood Experience is a location-based narrative using Mixed Reality effects to connect participants to unique and evocative real locations, bridging the gap between the real and story worlds. This paper describes the experience and a detailed evaluation of it. The experience itself centers around a narrative told by the “mayor” of Westwood. He tells a love story from his youth when he first came to Westwood, and intermixes the story with historical information. Most of this story is told on a mobile computer, using Mixed Reality and video for illustration. We evaluate the experience both quantitatively and qualitatively to find lessons learned about the experience itself and general guidelines for this type of experience. The analysis and guidelines from our evaluation are grouped into three categories: narration in mobile environments, social dynamics, and Mixed Reality effects.
Cascaded Reference Governor–MPC for Motion Control of Two-Stage Manufacturing Machines (2018)

Two-stage processing machines for manufacturing are equipped with two sets of actuators for motion control with different operating ranges and bandwidths. The processing time, product quality, and flexibility of the manufacturing process can be optimized by coordinating these actuators and exploiting the entire actuator operating range. We propose a motion control strategy for two-stage processing machines based on the model predictive control (MPC). By exploiting timescale separation, we formulate the problem as a single-stage motion control with reference-dependent constraints. The feasibility of the MPC problem is guaranteed by using a reference governor that adjusts the feed rate. The proposed method guarantees correct processing while satisfying the actuators' range and dynamics constraints, finite-time processing of a given spatial pattern, and real-time execution even with limited computational resources. Simulation and experimental results on a real processing pattern are shown for a scaled laboratory demonstration machine.
Advances in Flexible AIR™ Coil Technology for Neuro, Body, MSK, Breast and MNS Applications (2021)

Since the advent of the MRI phased array there has been a continual evolution of the technology with increasing element density and accommodation for parallel imaging. In more recent years there has been a move towards the development of ultra-flexible coil technology which affords more conformality to the human form and detection elements closer to the body. To accommodate such flexible technology some critical advances in electronic miniaturization, cable management and element-to-element immunity has had to be tackled. Examples of highly decoupled elements have been shown in the literature [1] [2] [3] . This has led to the exploration of possible wearable coils for a variety of body regions and we examine here some of those have been prototyped using AIR™ Coil technology [4] [5] [6] [7] . At the same time multi-nuclear arrays are also being developing with high channel count, which have the same need for patient conformality and higher SNR [8] . In this work we explore the expanding interest in flexible array technology for applications with both 1H and 13C nuclei and provide examples that have built, tested and evaluated. Specifically, novel wearable receive coils were constructed on fabric including (a) Head / Neck (b) Pelvis, (c) Bilateral brachial plexus, (d) Breast, and (e) a large body sized 13C receive blanket. The coils were designed to accommodate the 5th percentile woman up to the 99th percentile male. The flexible neck, pelvic, brachial plexus arrays were made using a highly flexible 1mm conductor construction. A 32.1MHz 16Ch array was made for 13C body imaging made using a conductor construction of 2.3mm diameter. Pre-amplification, decoupling and matching circuitry is included in a discrete module connected to the Air™ loop conductor. No loss in coil sensitivity relative to conventional 2oz copper PCB technology was found.
Signal and noise transfer properties of CMOS based active pixel flat panel imager coupled to structured CsI:Tl (2008)

Complementary metal-oxide-semiconductors (CMOS) active pixel sensors can be optically coupled to CsI:Tl phosphors forming a indirect active pixel flat panel imager (APFPI) for high performance medical imaging. The aim of this work is to determine the x-ray imaging capabilities of CMOS-based APFPI and study the signal and noise transfer properties of CsI:Tl phosphors. Three different CsI:Tl phosphors from two different vendors have been used to produce three system configurations. The performance of each system configuration has been studied in terms of the modulation transfer function (MTF), noise power spectra, and detective quantum efficiency (DQE) in the mammographic energy range. A simple method to determine quantum limited systems in this energy range is also presented. In addition, with aid of monochromatic synchrotron radiation, the effect of iodine characteristic x-rays of the CsI:Tl on the MTF has been determined. A Monte Carlo simulation of the signal transfer properties of the imager is also presented in order to study the stages that degrade the spatial resolution of our current system. The effect of using substrate patterning during the growth of CsI:Tl columnar structure was also studied, along with the effect of CsI:Tl fixed pattern noise due to local variations in the scintillation light. CsI:Tl fixed pattern noise appears to limit the performance of our current system configurations. All the system configurations are quantum limited at 0.23 microC/kg with two of them having DQE (0) equal to 0.57. Active pixel flat panel imagers are shown to be digital x-ray imagers with almost constant DQE throughout a significant part of their dynamic range and in particular at very low exposures.
Microchip-based immunoassay system with branching multichannels for simultaneous determination of interferon-γ (2002)

A bead-bed immunoassay system suitable for simultaneous assay of multiple samples was constructed on a microchip. The chip had branching multichannels and four reaction and detection regions; the constructed system could process four samples at a time with only one pump unit. Interferon gamma was assayed by a 3-step sandwich immunoassay with the system coupled to a thermal lens microscope as a detector. The biases of the signal intensities obtained from each channel were within 10%, and coefficients of variation were almost the same level as the single straight channel assay. The assay time for four samples was 50 min instead of 35 min for one sample in the single-channel assay; hence higher throughput was realized with the branching structure chip.
Dynamic Performance Improvement and Peak Power Limiting Using Ultracapacitor Storage System for Hydraulic Mining Shovels (2014)

This paper presents a concept to improve the dynamic response, efficiency, productivity, and fuel consumption of hydraulic mining shovels (HMSs) using a high power energy storage system to supplement the existing diesel-powered generators. A 2.25-MW ultracapacitor system is applied to improve the sluggish dynamic response of the diesel engine during sudden load changes and to limit the engine power requirements by maintaining an optimal engine speed. When the load rate of change increases above a specified rate limit, the ultracapacitor system supplements power to support loads in order to limit the power ramp rate for the generator. In addition to the engine dynamic improvement, the ultracapacitor system supports the engine during peak power demand, allowing for a smaller engine size for the machine, which results in higher fuel savings and less exhaust emissions. An interleaved bidirectional dc/dc converter is designed to interface between the ultracapacitor bank and main dc bus. Sophisticated multilayer control strategies are designed, implemented, and applied to the system to perform complete machine power management while keeping the dc bus voltage stable. Modeling and experimental results for an 8000-hp HMS with the novel electrification architecture have also been presented.
A unified operating environment for customer servicing (2002)

The authors present an operating environment for customer servicing, describing a platform and guidelines for consistent development of integrated end-to-end servicing. The environment covers all aspects of end-to-end operations, administration, and maintenance. Driven by customer needs, competition, technology, and the operations center evolution, the environment builds on the foundation of the Unified Network Management Architecture to define service-driven functional requirements for network elements and operations support systems (OSS) used by the AT&T Network Services Division. The end-to-end environment includes customer premises equipment, the core interexchange network, and local exchange carrier access. An internal version of the ACCUMASTER Integrator is a key element of the integrated OS architecture. A working prototype, the integrated testing prototype, built for near-term study of the integrated testing portion of the architecture, has yielded good feedback from customers and work-center staff.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
<title>Liquid-crystal polarization camera</title> (1992)

We present a fully automated system which unites CCD camera technology with liquid crystal technology to create a polarization camera capable of sensing the polarization of reflected light from objects at pixel resolution. As polarization affords a more general physical description of light than does intensity, it can therefore provide a richer set of descriptive physical constraints for the understanding of images. Recently, it has been shown that polarization cues can be used to perform dielectric/metal material identification, specular and diffuse reflection component analysis, as well as complex image segmentations that would be immensely more complicated or even infeasible using intensity and color alone. Such analysis has so far been done with a linear polarizer mechanically rotated in front of a CCD camera. The full automation of resolving polarization components using liquid crystals not only affords an elegant application, but reduces the amount of optical distortion present in the wobbling of a mechanically rotating polarizer. In our system two twisted nematic liquid crystals are placed in front of a fixed polarizer placed in front of a CCD camera. The application of a series of electrical pulses to the liquid crystals in synchronization with the CCD camera video frame rate produces a controlled sequence of polarization component images that are stored and processed on Datacube boards. We present a scheme for mapping polarization states into hue, saturation, and intensity which is a very convenient representation for a polarization image. Our polarization camera outputs such a color image which can then be used in polarization- based vision methods. The unique vision understanding capabilities of our polarization camera system are demonstrated with experimental results showing polarization-based dielectric/metal material classification, specular reflection, and occluding contour segmentations in a fairly complex scene, and surface orientation constraints for object recognition.
Survey of Smoking Habits and Attitudes of Patients and Staff in Psychiatric Hospitals (1993)

One hundred and six staff members and 150 patients of three psychiatric hospitals in Israel were administered a smoking habit and attitudes questionnaire. Upon analyzing the data, staff members and patients made up a very high percentage of smokers, 48.1 and 76%, respectively. The staff was not knowledgeable enough about the hazards of smoking. Nurses generously used cigarettes in order to appease the patients. Furthermore, the patients admitted being encouraged to smoke by the staff. According to these findings, a patient hospitalized in the psychiatric hospitals surveyed is significantly exposed to the pro-smoking atmosphere and the hazards of smoking.
Early reconstitution of the T‐cell repertoire after non‐myeloablative peripheral blood stem cell transplantation is from post‐thymic T‐cell expansion and is unaffected by graft‐versus‐host disease or mixed chimaerism (2003)

To study immune recovery after non-myeloablative, reduced-intensity stem cell allografts (NST) and T-cell-depleted myeloablative transplants (TCD), we measured T-cell subset recovery by flow cytometry, T-cell repertoire by spectratyping and thymic T-cell output using a T-cell receptor excision circle (TREC) assay. We found a rapid and comparable increase in lymphocyte numbers in both NST and TCD, supporting the presence of a powerful drive for lymphocyte recovery after transplant. Spectratyping on d 45 and 100 revealed almost complete normalization of the T-cell repertoire in NST patients by d 45, whereas TCD patients demonstrated marked skewing of the repertoire, persisting to d 100. After NST, there was a significantly higher number of TREC-positive CD4+ and CD8+ cells (P = 0.02 and P = 0.01 respectively). However, in both NST and TCD, early T-cell recovery after transplant appeared to result entirely from post-thymic T cells, the expansion pattern of which is most influenced by the starting T-cell dose, but not markedly by graft-versus-host disease (GVHD) or mixed chimaerism. These results define important qualitative differences in the T-cell repertoire according to the type of transplant schedule used.
Plasma based improvements in fuel cells (2008)

This paper concentrates on plasma sputtering of nano-aggregates of platinum catalyst, plasma deposition of open structure electrodes based on carbon nano-fibres and on plasma deposited membranes having properties similar to commercial products. Deposition of material for high temperature solid oxide fuel cells is presented. And comparison of the role of fuel cells in developing hydrogen economy and in hydrocarbon economy is also reported.
Realization and validation of the detector-based absolute integrating sphere method for luminous-flux measurement at KRISS (2012)

We present two detector-based realizations of the absolute integrating sphere method for luminous-flux measurement. A large-size realization with a sphere diameter of 2 m is applied to high-flux lamps above 1000 lm, and a small-size realization with a sphere diameter of 0.3 m to low-flux lamps below 100 lm. The uncertainty of both realizations is analysed with a focus on the systematic effect in the spatial mismatch correction, and evaluated to be 1.2% and 1.1% (k = 2) for the large-size and small-size realizations, respectively. Comparison with a goniophotometer using two different types of lamp artefacts for both cases has verified the validity of the realization within the comparison uncertainty.
Probiotics for intestinal decolonization of ESBL-producing Enterobacteriaceae: a randomized, placebo-controlled clinical trial (2019)

Successful EPE eradication was observed in very few individuals. This trial did not support Vivomixx® as being superior to placebo for intestinal decolonization in adult patients with chronic colonization of EPE, but was limited in power.
Photochemical Study of Tris(benzotriazol-1-yl)methane (2007)

Photodecomposition of tris(benzotrizol-1-yl)methane (1) in benzene gives [1-benzotryazol-1-yl-methylidene]-biphenyl-2-ylamine (2) resulting from the loss of the benzotriazolyl radical and nitrogen followed by addition of benzene. Elimination of the second benzotriazolyl radical from 2 provides the biphenyl-2-ylmethyleneamine radical, which affords phenantridine (3) after ring closure. In contrast, the photolysis of 1 in methanol gives a high yield of benzotriazole (4).
Brain-implantable biomimetic electronics as neural prosthetics (2003)

Described in this paper is an interdisciplinary effort that will enable the functions of specific brain damaged regions to be replaced by "neurocomputational" microchips that incorporate experimentally-based mathematical models of the nonlinear dynamic properties of biological neurons. To allow the "neurocomputational" microchips to communicate with existing brain tissue, another microcircuitry element has been developed silicon-based multi-electrode arrays that are "neuromorphic", i.e., designed to conform to the region-specific cytoarchitecture of the brain. When the "neurocomputational" and "neuromorphic" components are fully integrated, the envisioned prosthetic will receive electrical impulses from targeted subregions of the brain, process the information using the hardware model of that brain region, and communicate back to the functioning brain.

Robust Motion Planning for Uncertain Systems With Disturbances Using the Invariant-Set Motion Planner (2020)

The invariant-set motion planner uses a collection of safe sets to find a collision-free path through an obstacle-filled environment [1]-[4]. This article extends the invariant-set motion planner to systems with persistently varying disturbances and parametric model uncertainty. This is accomplished by replacing the previously used positive invariant sets with robust positive invariant sets. Since the model uncertainty obfuscates the relationship between the invariant sets in the state space, and the references and obstacles in the output space, we reformulate the dynamics in velocity form so that the system output appears directly in the modified system state. Since the persistently varying disturbances will prevent the closed-loop system from converging to the desired reference, we introduce a new robust connection rule where references are connected when the invariant set of one reference contains the minimal volume robust invariant-set of another. In addition, we bound the time required to transition between invariant sets to ensure safety when the obstacles are moving. By parameterizing the invariant sets using a precomputed input-to-state Lyapunov function, we reduce the real-time computational complexity of our motion planner. The robust invariant-set motion planner is demonstrated for an automated highway driving case study.
Minimum energy communication over a relay channel (2003)

The paper investigates limits on the energy-per-bit required for reliable communication over AWGN relay channels. Upper and lower bounds on the minimum energy-per-bit that are not tight, but whose ratio is less than 2 are found. Tighter bounds on minimum energy-per-bit are also found for two frequency-division AWGN relay channel models.

This paper presents an investigation on miniature antenna effect on the ear-to-ear channel. An active ultra-compact antenna design suited for hearing aid electronic device is presented. The effect of antenna location inside the ear on both antenna properties and ear-to-ear radio channel is investigated, by considering a simplified spherical model of the human head and a Specific Anthropomorphic Mannequin (SAM) phantom.
Ethylene Polymers,HDPE (2015)

High density polyethylene (HDPE) is the most widely used type of polyethylene. It was invented in the early 1950s and commercial catalytic processes were quickly developed based on three different transition metals: Cr, Mo, and Ti. Development of many different grades of HDPE followed, which are currently manufactured by various commercial processes. The molecular structure of HDPE vary widely to produce polymers of various molecular weight, molecular weight distribution, end group composition, and other characteristics, which in turn, affect properties such as stiffness of the polymer, the gloss or clarity, tear resistance, chemical resistance, and electrical insulation properties. The low melting point and high chemical stability of HDPE facilitate its processing by many conventional techniques, including injection molding, blow molding, and blown and cast film. Common uses for HDPE include food packaging, bottles, bags, medical applications, drums, fuel tanks and other automotive parts, pipe, toys, film, and fiber and many specialized applications, eg, in prosthetic devices, and hip or knee joint replacements.
