Motion compensated digital subtraction angiography (1999)

Digital subtraction angiography, whether based on traditional X-ray or MR, su#ers from patient motion artifacts. Until now, the usual remedy is to pixel shift by hand, or in some cases performing a global pixel shift semi-automatically. This is time consuming, and cannot handle rotations or local varying deformations over the image. Wehave developed a fully automatic algorithm that provides for motion compensation in the presence of large local deformations. Our motion compensation is very accurate for ordinary motions, including large rotations and deformations. It does not matter if the motions are irregular over time. For most images, it takes about a second per image to get adequate accuracy. The method is based on using the phase from #lter banks of quadrature #lters tuned in di#erent directions and frequencies. Unlike traditional methods for optical #ow and correlation, our method is more accurate and less susceptible to disturbing changes in the image, e.g. amoving contrast bolu...

Role of cytokines in inflammatory bowel disease. (1995)

The authors review the recent literature about the proinflammatory role of interleukins-1,-2,-6,-8, tumour necrosis factor and interferon-gamma in Crohn's disease and ulcerative colitis, as well as their possible use to assess disease activity and to design new therapeutic approaches. Most cytokines were secreted in excess in inflammatory bowel disease. An imbalance between interleukin-1 and interleukin-1 antagonist might be a factor responsible of the chronicity of intestinal lesions. Circulating levels of interleukin-2 receptor are related to disease activity. Preliminary data on the therapeutic use of antibodies to tumour necrosis factor are encouraging.
In vitro and in vivo inhibition of ortho- and paramyxovirus infections by a new class of sulfonic acid polymers interacting with virus-cell binding and/or fusion (1994)

A series of sulfonic acid polymers were shown to be potent and selective inhibitors of respiratory syncytial virus (RSV) and influenza A virus. The compounds inhibit the replication of RSV and influenza A virus in HeLa and MDCK cells, at concentrations of 0.16 and 4.0 micrograms/ml, respectively, and are nontoxic to growing cells at concentrations of > 100 micrograms/ml. The mode of antiviral action of the sulfonic acid polymers can be ascribed to inhibition of virus-cell fusion (for influenza A virus) or inhibition of both virus-cell binding and fusion (for RSV). The sulfonic acid prototype PAMPS [poly(2-acrylamido-2-methyl-1-propanesulfonic acid)], when administered intranasally to mice as a single dose of 10 or 50 mg per kg of body weight at the time of infection, completely inhibited influenza A virus replication (in lungs) and virus-associated lung consolidation in immunocompetent mice and completely protected NMRI and SCID (severe combined immune deficiency) mice against influenza A virus-associated mortality. When administered 1 h before or after virus inoculation, no protective effect was observed at a dose of 10 or 100 mg/kg. Sulfonic acid polymers exert selective inhibitory effects on RSV and influenza A virus replication.
Transient bicarrier response in high-k dielectrics and its impact on transient charge effects in high-k complementary metal oxide semiconductor devices (2006)

In this letter, transient charge trapping and detrapping characteristics in high-k n∕p metal oxide semiconductor field effect transistors (MOSFETs) were studied. Transient charge trapping was found to be an interface thickness-limited phenomenon. Additionally, transient trapping of electrons, rather than holes, was found to be dominant even in pMOSFETs. Transient charge recombination or bicarrier response within the high-k layer was the main reason for the dependence on input signal in high-k devices. Detrapping characteristics for nMOSEFTs and pMOSFETs were correlated to the transient hole and electron trappings, respectively.

Prevention of Senescence Progression in Reversibly Immortalized Human Ensheathing Glia Permits Their Survival After Deimmortalization (2009)

Reversible immortalization holds great potential for primary tissue expansion to develop cell-based therapies as well as for basic research. Human olfactory ensheathing glia (hOEG) are promising candidates for treating spinal cord injury and for studying extrinsic neuroregenerative mechanisms. We used lentivectors with Cre/loxP technology to achieve reversible gene transfer of BMI1, SV40 large T antigen (TAg), a short hairpin RNA against p53 (shp53), and the catalytic subunit of telomerase (TERT) in primary cultures of hOEG from human donor cadaver olfactory bulbs. Several combinations of these genes were able to immortalize hOEG, conserving their antigenic markers and neuroregenerative properties but only those transduced by BMI1/TERT did not accumulate karyotypic alterations or increase senescence marker levels. Strikingly, these were also the only cells which continued to proliferate after transgene removal by Cre recombinase delivery, whereas hOEG immortalized by shp53 or TAg in combination with TERT entered into growth arrest and died. These data support the idea that immortalization and halting senescent changes are separate processes; hOEG immortalized by BMI1/TERT can revert back to their former primary cell replicative state when deimmortalized, whereas those transduced by the other combinations depend on the presence of these transgenes to maintain their aberrant proliferative state.
Design of UV-visible dual-spectrum image fusion system based on DSP technology (2009)

Based on high speed Digital Signal Processor (DSP), a UV-Visible dual-spectrum image capture, processing and display system was developed. As an innovative light path with the spectrum transformation and image enhancement technologies were adopted, the system could detect real-time images of various UV emitting phenomena. The image processing part, where TMS320DM642 served as the center processor, realized functions of image decode and code, processing and export. Algorithms of image fusion were designed to locate the ultraviolet signals. Compared with traditional image processing based on computer, the adoption of DSP not only greatly improved image processing speed, but also made this system miniature and portable. This system based on embedded structure could be applied broadly in the detection of weak signals of fires, plumes and electrical corona and so on.
Conserved RNA secondary structures in Picornaviridae genomes (2001)

The family Picornaviridae contains important pathogens including, for example, hepatitis A virus and foot-and-mouth disease virus. The genome of these viruses is a single messenger-active (+)-RNA of 7200-8500 nt. Besides coding for the viral proteins, it also contains functionally important RNA secondary structures, among them an internal ribosomal entry site (IRES) region towards the 5'-end. This contribution provides a comprehensive computational survey of the complete genomic RNAs and a detailed comparative analysis of the conserved structural elements in seven of the currently nine genera in the family PICORNAVIRIDAE: Compared with previous studies we find: (i) that only smaller sections of the IRES region than previously reported are conserved at single base-pair resolution and (ii) that there is a number of significant structural elements in the coding region. Furthermore, we identify potential cis-acting replication elements in four genera where this feature has not been reported so far.
Layer position accuracy in powder‐based rapid prototyping (1995)

Emerging technologies commonly known as “rapid prototyping” fabricate solid objects directly from computer models by building parts in thin layers. Three‐dimensional printing is one such process that creates engineering prototypes and tooling by joining powder particles selectively on a layer‐by‐layer basis. The powder‐based approach offers tremendous flexibility in geometry and materials, but it makes layer position accuracy a fundamental concern for dimensional control in the vertical direction. Ideally, each powder layer is generated at a vertical position that remains fixed, at a prescribed distance with respect to a machine reference. However, compressive loads imparted to a stack of layers (by the weight of subsequent layers, for example) may cause the layers to displace downward. Develops a model for layer displacement using experimental data for compressibility and applied load. Compares predictions made from the model to measured displacements, and the predictions successfully captured the relative magnitudes of actual errors at various positions within layered powder beds. Position changes were most severe in the middle regions of the powder beds, with diminishing magnitude towards the top and bottom. Uses aluminium oxide powder in two different sizes (approximately of 10‐micron and 30‐micron diameter) and two different shapes (platelet and spherical) in the studies. The average measured displacement in a 76.2mm deep bed ranged from 23 microns for a 30‐micron platelet‐shaped powder to over 260 microns for a 9‐micron platelet‐shaped sample.
Human RANTES acts as a receptor antagonist for guinea pig eotaxin in vitro and in vivo (1996)

The guinea pig C-C chemokine, eotaxin, is a potent and selective eosinophil chemoattractant in guinea pig airways and skin in vivo, and stimulates both guinea pig and human eosinophils in vitro. The human C-C chemokine RANTES (30% homology with guinea pig eotaxin) stimulates human eosinophils in vitro, but does not stimulate guinea pig eosinophils, even though these cells bind 125I-RANTES. Similar concentrations of eotaxin and unlabeled RANTES competitively inhibit the binding of 125I-RANTES to guinea pig eosinophils, suggesting that eotaxin and RANTES share a common binding site on these cells. In the present study, we investigated the possibility that human RANTES, binding to a putative eotaxin receptor on guinea pig eosinophils, might block functional responses to eotaxin. When fura-2-loaded cells were first exposed to RANTES, which failed to elevate the intracellular calcium concentration, the response to a subsequent challenge with eotaxin was inhibited in a dose-dependent manner. Inhibition was also demonstrated when the two chemokines were added simultaneously. Another human C-C chemokine, MCP-3 (52% homology with guinea pig eotaxin), had similar inhibitory effects on the eotaxin-induced activation of guinea pig eosinophils in vitro. RANTES inhibited (111)In-eosinophil accumulation in response to intradermal eotaxin in vivo. In contrast, RANTES had no significant effect on responses to leukotriene B4 in vitro or in vivo. Thus, these experiments in the guinea pig demonstrate that human RANTES is the first prototypic antagonist of an eotaxin receptor.
Performance, Management and Testing Requirements for Hybrid Electric Vehicle Batteries (1998)

Hybrid electric vehicles (HEVs) have several potential advantages over traditional internal combustion engine (ICE) vehicles. They promise higher fuel economy and lower emissions without sacrificing vehicle performance and range. They can also take advantage of the existing fuel delivery infrastructure which may facilitate their acceptance by the consumer. High performance electrochemical battery systems are the most promising candidates for providing peak power for HEVs in the near future. However, the specific requirements these batteries must meet (higher specific power, good high rate charge acceptance, low self discharge) are much more stringent than for any other application. This paper summarizes general test requirements and procedures used in the development and characterization of battery packs and management system for hybrid electric vehicles. A comparison of the capabilities of existing test equipment is also given.
Study on the fabrication of low-pass metal powder filters for use at cryogenic temperatures (2016)

We fabricated compact low-pass stainless-steel powder filters for use in low-noise measurements at cryogenic temperatures and investigated their attenuation characteristics for different wire lengths, filter shapes, and preparation methods at frequencies up to 20 GHz. We used nominally 30-μm-sized SUS 304L powder and mixed it with Stycast 2850FT (Emerson and Cumming) with catalyst 23LV. A 0.1-mm insulated copper wire was wound on preformed powder-mixture spools in the shape of a right-circular cylinder, a flattened elliptic cylinder and a toroid, and the coils were encapsulated in metal tubes or boxes filled with the powder mixture. All the fabricated powder filters showed a large attenuation at high frequencies with a cut-off frequency near 1 GHz. However, the toroidal filter showed prominent ripples corresponding to resonance modes in the 0.5-m-long coil wire. A filter with a 2:1 powder/epoxy mixture mass ratio and a wire length of 1.53 m showed an attenuation of −93 dB at 4 GHz, and the attenuation was linearly proportional to the wire’s length. As the powder-to-epoxy ratio was increased, the high-frequency attenuation increased. An equally-spaced single-layer coil structure was found to be more efficient in attenuation than a double-layer coil. The geometry of the metal filter’s case affected the noise ripples, with the least noise being found for a circular tube.
Ask a better question, get a better answer a new approach to private data analysis (2007)

Abstract. Cryptographic techniques for reasoning about information leakage have recently been brought to bear on the classical problem of statistical disclosure control – revealing accurate statistics about a population while preserving the privacy of individuals. This new perspective has been invaluable in guiding the development of a powerful approach to private data analysis, founded on precise mathematical definitions, and yielding algorithms with provable, meaningful, privacy guarantees. 1
Implementation of cell-free biological networks at steady state (2013)

Living cells maintain a steady state of biochemical reaction rates by exchanging energy and matter with the environment. These exchanges usually do not occur in in vitro systems, which consequently go to chemical equilibrium. This in turn has severely constrained the complexity of biological networks that can be implemented in vitro. We developed nanoliter-scale microfluidic reactors that exchange reagents at dilution rates matching those of dividing bacteria. In these reactors we achieved transcription and translation at steady state for 30 h and implemented diverse regulatory mechanisms on the transcriptional, translational, and posttranslational levels, including RNA polymerases, transcriptional repression, translational activation, and proteolysis. We constructed and implemented an in vitro genetic oscillator and mapped its phase diagram showing that steady-state conditions were necessary to produce oscillations. This reactor-based approach will allow testing of whether fundamental limits exist to in vitro network complexity.
Holistic dentistry: disease is a result of social, psychological, and physical factors. (1978)

President Roosevelt has given strict instructions for officeholders to abstain from advocating his reelection at the Republican National Convention as it would be a "serious violation of official propriety." Despite this, Governor Curry has publicly declared his support.
Electric deregulation impacts on metering, billing and customer information systems (2002)

Electric industry deregulation is approaching in many states, bringing with it enormous changes in the way that distribution utilities handle information within their customer information, metering and billing systems. Traditional utility metering and billing processes could largely become a thing of the past when such concepts as retail open access, 3/sup rd/ party metering and competitive billing services become the norm. In addition, distribution utilities will be required to develop electronic data interchange capabilities with many other entities that did not exist prior to the advent of retail competition. This paper examines a number of business processes in the retail electric market and explores the information that will be required to implement those processes.
An evaluation of ultrasound and nuclear magnetic resonance spectroscopy to measure in vivo intramuscular fat content of longissimus muscle of pigs. (1997)

Intramuscular fat content (IMF) of longissimus muscle of pigs growing from approximately 20 to 100 kg was measured in vivo using biopsies after complete or localized anaesthesia, ultrasound and 1H nuclear magnetic resonance (NMR) technology. Three lines of pigs, with 60 animals each, were available. Biopsies were taken from the same pigs at 20, 60, and 100 kg, and fat was extracted for gravimetric determination. At 20 kg, ultrasound images were collected, and in vivo 1H NMR spectroscopy was applied. A-mode ultrasound measurements were collected at 60 and 100 kg. The overall mean value of IMF was 1.60 ± .56% at 20 kg, 1.53 ± .50% at 60 kg, and 1.71 ± .60% at 100 kg. Interactions between lines and body weight were observed. No statistically significant differences were found between methods at 20 kg. No significant correlations were found between the A-mode ultrasound measurements and the mean values of the gravimetric measurements. No visible pain or infections were observed in relation to the collection of a single biopsy. The ultrasound method in combination with image analysis is advantageous from the labor point of view and will also improve welfare of pigs in case of repeated sampling. However, further research is necessary to make the technology sufficiently reliable. A correlation between IMF and backfat thickness was not found.

Computer lipreading for improved accuracy in automatic speech recognition (1996)

Among the various methods that have been proposed to improve the robustness and accuracy of automatic speech recognition (ASR) systems, lipreading has received little attention until very recently. However, results from the psychological literature indicate that lipreading, in conjunction with auditory perception, can provide a strong improvement in speech recognition and understanding in humans. We have developed a novel speaker-dependent lipreading system that uses hidden Markov models. An audiovisual system known as Lipreading to Enhance Automatic Perception of Speech (LEAPS) is described, in which the lipreading system is used in conjunction with an audio ASR system in order to improve the accuracy of the latter, especially under degraded acoustical conditions. Experimental results are presented for two small phoneme discrimination tasks, as well as a medium vocabulary isolated word recognition task. In all cases, performance of the combined system is superior to that of the audio system, with a reduction in errors ranging from 20 to 65%.
Effect of the H<sub>1</sub> Antihistamine Chlorpheniramine Maleate on Histamine‐Induced Symptoms in the Human Conjunctiva (1982)

Earlier studies have shown that intranasal chlorpheniramine (0.77%) can inhibit histamine-induced tickling, sneezing, and hypersecretion by a local effect on nerve fibres. The aim of the present study was to examine whether this solution had local anaesthetic of parasympatholytic properties. If neither of these properties are present it suggests that the anti-pruritic effects of the solution are caused by inhibition of H1 receptors, which in turn is indirect evidence for the presence of H1 receptors on nerve fibers. In a double-blind design 15 normal subjects were provoked with histamine in the eye after pretreatment with chlorpheniramine or with a local anaesthetic, oxybuprocain. Both drugs inhibited itching, but the H1 antihistamine was significantly more effective than the local anaesthetic (P less than 0.01). Corneal sensitivity was measured by an esthesiometer, and pupil difference was used as a measure for atropine activity. Chlorpheniramine had neither a local anaesthetic nor a parasympatholytic effect. This study has therefore strengthened the hypothesis that there are nervous H1 receptors in the mucous membranes of the eye and airways and has extended its application in animals to also include man.
Nucleic Acid and Protein Synthesis in Reconstituted Lyophilized <i>Escherichia coli</i> Exposed to Air (1972)

S ummary : Escherichia coli strain BT ‐ , freeze dried from distilled water, loses viability by exposure to air in the dry state, and decay curves of such bacteria were determined. The amounts of tritiated thymidine incorporated in the DNA of such ‘dead’, rehydrated bacteria are compatible with an assumption that the synthesis of DNA proceeds till the completion of its replication cycle, but not beyond. Induction of β‐galactosidase served as an indicator of RNA and protein synthesis in the dead bacteria. Such induction occurred after a short lag after which it proceeded at a rate similar to that observed in lyophilized, untreated bacteria. The loss of viability of these bacteria cannot be accounted for by defects in the production of DNA or RNA and protein synthesis; it is most probably due to damage to the DNA initiation point.
