Stereoscopic (3D) projection display using polarized color multiplexing (1990)

A technique has been developed and demonstrated to present full color stereoscopic imagery using standard projection display systems. This polarized color multiplexing technique (patent application filed) does not require additional image sources beyond those contained within the original 2-D display system. A full-resolution image is delivered to each eye, without increasing the video bandwidth of the original display. The approach separates the primary image colors between right eye and left eye views and uses polarization to alternate the colors every frame, thus generating a full color 3-D image on the projection screen. Any stereopair video source can be used, such as dual cameras, dual VCRs, or computer generated imagery. Either commercially available or custom threechannel projection systems (CRT, light valve, or laser) can be transformed into a stereoscopic display for group viewing.

A dosimetric comparison of stereotactic body radiation therapy techniques for lung cancer: robotic versus conventional linac‐based systems (2010)

The aim of this study is to compare the dosimetric characteristics of robotic and conventional linac-based SBRT techniques for lung cancer, and to provide planning guidance for each modality. Eight patients who received linac-based SBRT were retrospectively included in this study. A dose of 60 Gy given in three fractions was prescribed to each target. The Synchrony Respiratory Tracking System and a 4D dose calculation methodology were used for CyberKnife and linac-based SBRT, respectively, to minimize respiratory impact on dose calculation. Identical image and contour sets were used for both modalities. While both modalities can provide satisfactory target dose coverage, the dose to GTV was more heterogeneous for CyberKnife than for linac planning/delivery in all cases. The dose to 1000 cc lung was well below institutional constraints for both modalities. In the high dose region, the lung dose depended on tumor size, and was similar between both modalities. In the low dose region, however, the quality of CyberKnife plans was dependent on tumor location. With anteriorly-located tumors, the CyberKnife may deliver less dose to normal lung than linac techniques. Conversely, for posteriorly-located tumors, CyberKnife delivery may result in higher doses to normal lung. In all cases studied, more monitor units were required for CyberKnife delivery for given prescription. Both conventional linacs and CyberKnife provide acceptable target dose coverage while sparing normal tissues. The results of this study provide a general guideline for patient and treatment modality selection based on dosimetric, tumor and normal tissue sparing considerations.
Simulation of GaAs submicron FET with hot-electron injection structure (1983)

Two-dimensional Monte Carlo simulation of a 0.25 μm-long GaAs FET with an (Al, Ga)As/GaAs heterojunction source is reported for the first time. The mean electron velocity reaches above 7 × 107 (cm/s) in the channel, and extremely high values of Id = 11 (mA/20 μm) and gm = 1250 (mS/mm) are obtained. The unity-current-gain frequency fr is found to reach about 250 GHz.
On Atmospheric Loss of Oxygen Ions from Earth Through Magnetospheric Processes (2001)

In Earth's environment, the observed polar outflow rate for O(+) ions, the main source of oxygen above gravitational escape energy, corresponds to the loss of approximately 18% of the present-day atmospheric oxygen over 3 billion years. However, part of this apparent loss can actually be returned to the atmosphere. Examining loss rates of four escape routes with high-altitude spacecraft observations, we show that the total oxygen loss rate inferred from current knowledge is about one order of magnitude smaller than the polar O(+) outflow rate. This disagreement suggests that there may be a substantial return flux from the magnetosphere to the low-latitude ionosphere. Then the net oxygen loss over 3 billion years drops to approximately 2% of the current atmospheric oxygen content.
Activation of internodal potassium conductance in rat myelinated axons. (1993)

1. Voltage changes associated with currents crossing the internodal axolemma were monitored using a microelectrode inserted into the myelin sheath (peri-internodal region) of rat phrenic nerve fibres. This microelectrode was also used to change the potential and the ionic environment in the peri-internodal region. 2. Following stimulation of the proximal nerve trunk, the peri-internodal electrode recorded a positive-going action potential whose amplitude increased (up to 75 mV) with increasing depth of microelectrode penetration into the myelin. The resting potential recorded by the peri-internodal electrode remained within 4 mV of bath ground. 3. Confocal imaging of fibres injected peri-internodally with the fluorescent dye Lucifer Yellow revealed a staining pattern consistent with spread of dye throughout the myelin sheath of the injected internode. 4. After ionophoresis of K+ (but not Na+) into the peri-internodal region, the action potential was followed by a prolonged negative potential (PNP) lasting hundreds of milliseconds to several seconds. The duration of the PNP increased as the frequency of stimulation decreased. PNPs could also be evoked by sub-threshold depolarization of the internodal axolemma with peri-internodally applied current pulses. In the absence of action potentials or applied depolarization PNPs sometimes appeared spontaneously. 5. Peri-internodal application of Rb+ also produced evoked and spontaneous PNPs. These PNPs had longer durations (up to 20 s) than those recorded from K(+)-loaded internodes. 6. Spontaneous action potentials sometimes appeared during the onset of the PNP, suggesting that PNPs are associated with depolarization of the underlying axon. 7. Passage of current pulses during the PNP demonstrated that the PNP is associated with an increased conductance of the pathway linking the peri-internodal recording site to the bath. At least part of this conductance increase occurs across the internodal axolemma, since peri-internodally recorded action potentials evoked during the PNP had larger amplitudes than those evoked before or after the PNP. 8. PNPs were suppressed by tetraethylammonium (TEA, 10-20 mM) and by 4-aminopyridine (1 mM). 9. These results suggest that the PNPs recorded in K(+)- or Rb(+)-loaded myelin sheaths are produced by a regenerative K+ or Rb+ current that enters the internodal axolemma via K+ channels opened by action potentials or subthreshold depolarizations. 10. When normal extracellular [K+] was preserved (by using Na+ rather than K+ salts in the peri-internodal electrode), action potentials recorded within the myelin sheath were instead followed by a brief, positive after-potential that was inhibited by TEA.(ABSTRACT TRUNCATED AT 400 WORDS)
Skeletal Muscle Specific FKBP12 Deficiency Reduces Force Production in Mouse EDL Muscle (2004)

1821 FKBP12 is a 12-kD binding protein that is known to bind to the immunosuppressive drug FK506 and to the sarcoplasmic reticulum Ca2+ release channel. The exact role of FKBP12 in the excitation-contraction coupling process remains unknown. PURPOSE: To examine the effects of skeletal muscle specific FKBP12 deficiency on contractile mechanics in mouse fast-twitch extensor digitorum longus (EDL) muscle in vitro. METHODS: Skeletal muscle specific FKBP12 deficient mice (i.e., conditional knockouts) were created using the CreLoxP gene recombination technique with Cre transgene expression under the regulation of the muscle creatine kinase promoter. Genotypes were confirmed using PCR analysis. EDL muscles from FKBP12 knockout and control (i.e., Cre transgenic) mice were dissected, and fatigability, caffeine sensitivity (1–50 mM), and isometric force as a function of stimulation frequency (10–300 Hz) were studied at 35°C. RESULTS: Body weight and EDL muscle wet weight were not different between FKBP12 knockout and control mice. Compared with control mice, absolute and specific isometric forces from FKBP12 knockout mice were reduced 16–30% and 22–36% at stimulation frequencies >60 Hz, respectively. Force normalized to peak isometric tetanic force indicated a rightward shift in the force-frequency relationship with the FKBP12 knockout mice. Although there was no difference in fatigability between groups, resting tension was elevated 29% at the end of the fatigue bout in FKBP12 knockout mice, whereas it was unchanged (−2%) in control mice. The ratio of contracture force at 50 mM caffeine to peak isometric twitch force (0 mM caffeine) was 54% greater in FKBP12 knockout mice than in controls. CONCLUSION: FKBP12 plays a significant role in regulating the excitationcontraction coupling process and force production in mouse EDL muscle. Supported by NIH grant 2 R01 AR41802–10.
Micromotion-induced dynamic effects from a neural probe and brain tissue interface (2014)

Neural probes contain the potential to cause injury to surrounding neural cells due to a discrepancy in stiffness values between them and the surrounding brain tissue when subjected to mechanical micromotion of the brain. To evaluate the effects of the mechanical mismatch, a series of dynamic simulations are conducted to better understand the design enhancements required to improve the feasibility of the neuron probe. The simulations use a nonlinear transient explicit finite element code, LS-DYNA. A three-dimensional quarter-symmetry finite element model is utilized for the transient analysis to capture the time-dependent dynamic deformations on the brain tissue from the implant as a function of different frequency shapes and stiffness values. When micromotion-induced pulses are applied, reducing the neuron probe stiffness by three orders of magnitude leads up to a 41.6% reduction in stress and 39.1% reduction in strain. The simulation conditions assume a case where sheath bonding has begun to take place around the probe implantation site, but no full bond to the probe has occurred. The analyses can provide guidance on the materials necessary to design a probe for injury reduction.
Blend: a Novel Combined MT Metric Based on Direct Assessment — CASICT-DCU submission to WMT17 Metrics Task (2017)

Existing metrics to evaluate the quality of Machine Translation hypotheses take different perspectives into account. DPM-Fcomb, a metric combining the merits of a range of metrics, achieved the best performance for evaluation of to-English language pairs in the previous two years of WMT Metrics Shared Tasks. This year, we submit a novel combined metric, Blend, to WMT17 Metrics task. Compared to DPMFcomb, Blend includes the following adaptations: i) We use DA human evaluation to guide the training process with a vast reduction in required training data, while still achieving improved performance when evaluated on WMT16 to-English language pairs; ii) We carry out experiments to explore the contribution of metrics incorporated in Blend, in order to find a trade-off between performance and efficiency.
Scalable network traffic visualization using compressed graphs (2013)

The visualization of complex network traffic involving a large number of communication devices is a common yet challenging task. Traditional layout methods create the network graph with overwhelming visual clutter, which hinders the network understanding and traffic analysis tasks. The existing graph simplification algorithms (e.g. community-based clustering) can effectively reduce the visual complexity, but lead to less meaningful traffic representations. In this paper, we introduce a new method to the traffic monitoring and anomaly analysis of large networks, namely Structural Equivalence Grouping (SEG). Based on the intrinsic nature of the computer network traffic, SEG condenses the graph by more than 20 times while preserving the critical connectivity information. Computationally, SEG has a linear time complexity and supports undirected, directed and weighted traffic graphs up to a million nodes. We have built a Network Security and Anomaly Visualization (NSAV) tool based on SEG and conducted case studies in several real-world scenarios to show the effectiveness of our technique.
Parallel, multi-dut testing in an open architecture test system (2006)

Parallel testing provides an increase in throughput without a corresponding increase in cost, by performing tests on multiple devices under test at the same time. Addition of this capability to a modular, re-configurable, open architecture test system paves the way for an even more cost-effective solution. This paper describes the parallel test strategy adopted in the T2000 tester from Advantest Corporation, which is based on the OPENSTARtrade platform
Clinical Diagnosis and Treatment of Ketosis (1971)

Ketosis afflicts lactating dairy cattle of all ages, increasing during peak production years. It may occur two to three weeks prepartum to four months postpartum. Common symptoms are diminished appetite, decreased milk, nervousness, profuse salivation, unnatural gait, licking themselves, grasping hard objects and damaging mouth, becoming explosively excited and unmanageable. Clinically, animals reveal lack of alertness, eyes lack luster, rumen is hard and partially empty and noisy, feces are abnormally firm, and urine is clear, showing characteristic color responses to the Ross modification of the Rothera test. Stress factors may cause ketosis such as high production, indigestion, milk fever, partial starvation, metritis, mastitis, and ovarian cysts.
An Approach to Discover Dependencies between Service Operations (2008)

Service composition is emerging as an important paradigm for constructing distributed applications by combining and reusing independently developed component services. One key issue of service composition is how to identify relevant service operations so as to compose services rapidly and correctly. A promising approach to simplifying the search of relevant service operations in service composition lies in the discovery of the dependencies between service operations. However, the discovery of operation dependencies is not a trivial task but a challenge. We propose an approach to discover operation dependencies in a personal problem solving environment. Our approach combines the semantic matching of inputs and outputs interfaces between service operations and the analysis of process cases to identify dependencies. The main contributions of the approach are: 1) It can be used to identify the direction of the dependencies. 2) It provides the method to measure the strength of dependencies. 3) Nonconflict property and non-redundancy property of discovered dependencies are guaranteed based on a dependency graph. Moreover, we experimentally demonstrate the efficacy of our approach by testing it under three typical bioinformatics scenarios.

Sensor data boundary estimation for anomaly detection in wireless sensor networks (2010)

Fuzzy boundaries and unpredictable anomalies displayed in the raw sensor data make the process of defining a strong ellipsoid boundary for the raw data in the ellipsoid-based anomaly detection algorithms in wireless sensor networks a difficult problem. We have shown, using synthetic and real sensor data, that the random variable that represents the difference between any two randomly selected raw data points follows an identically independently distributed Gaussian distribution. We have used this statistical property to calculate ellipsoid boundaries for the Gaussian distribution which displays a robust ellipsoid shape and then to map each point of the distribution function to its corresponding raw data point to isolate anomalies from the sensor data. We have demonstrated the performance of the proposed approach by comparing it with the standard approach using both synthetic datasets and real Intel Berkeley Research Laboratory and Grand St Bernard datasets.
Patellar tracking in primary total knee arthroplasty. (2006)

The patellofemoral articulation has been frequently overlooked as a significant contributor to the success of primary total knee arthroplasty. Neglecting the patellofemoral articulation frequently leads to abnormal patellofemoral tracking. To understand the concept of patellofemoral maltracking, the importance of the Q angle, mechanical alignment, femoral component rotation, tibial component positioning, patellar component positioning, patellar height, and patellar resurfacing as factors related to patellofemoral tracking and function must be considered. Greater attention to and understanding of these factors will lead to significant pain relief and overall patient satisfaction.

Virus-derived Platforms for Visualizing Protein Associations inside Cells (2007)

Protein-protein associations are vital to cellular functions. Here we describe a helpful new method to demonstrate protein-protein associations inside cells based on the capacity of orthoreovirus protein muNS to form large cytoplasmic inclusions, easily visualized by light microscopy, and to recruit other proteins to these structures in a specific manner. We introduce this technology by the identification of a sixth orthoreovirus protein, RNA-dependent RNA polymerase lambda3, that was recruited to the structures through an association with muNS. We then established the broader utility of this technology by using a truncated, fluorescently tagged form of muNS as a fusion platform to present the mammalian tumor suppressor p53, which strongly recruited its known interactor simian virus 40 large T antigen to the muNS-derived structures. In both examples, we further localized a region of the recruited protein that is key to its recruitment. Using either endogenous p53 or a second fluorescently tagged fusion of p53 with the rotavirus NSP5 protein, we demonstrated p53 oligomerization as well as p53 association with another of its cellular interaction partners, the CREB-binding proteins, within the inclusions. Furthermore using the p53-fused fluorescent muNS platform in conjunction with three-color microscopy, we identified a ternary complex comprising p53, simian virus 40 large T antigen, and retinoblastoma protein. The new method is technically simple, uses commonly available resources, and is adaptable to high throughput formats.
Optical particle detection integrated in a dielectrophoretic lab-on-a-chip (2001)

The design and fabrication of a dielectrophoretic 'lab-on-a-chip' device for bioparticle processing and counting is presented. The device consists of a multi-layer travelling wave dielectrophoretic electrode array for manipulating particles and/or fluids, microchannels for delivering samples and optical fibres for counting particles and/or measuring their velocities. Single particles were detected optically using either light scattering or fluorescence emission. The technology described in this study is potentially applicable to a range of particulate diagnostic systems.
