An active and reactive power regulating system based on a cascaded-converter (2010)

This paper describes an active and reactive power regulating system based on a cascaded converter. The system is intended for power leveling of renewable energy sources, as well as for improving power quality and reliability of a power distribution system. The active/reactive power control and the DC side voltage control concentrated in this paper are indispensable for the system's proper operation. A 6kV, 3MW/MVA simulation system is designed, constructed. Simulation results verify the viability and effectiveness of the performance.
Caustics and Convergence Zones in Deep-Water Sound Transmission (1965)

The existence and characteristics of deep convergence or focusing zones have been investigated by means of ray diagrams and field measurements using explosive charges dropped from an aricraft. The zones are found to migrate regularly with change of receiver depth, and exhibit at convergence gain of 5–10 dB for a source depth of 800 ft for the velocity profile applying for the field measurements. The pattern of the caustics that bound these zones in the deep ocean channel is a complex one, but can be roughly characterized as a series of double caustics branching out from the ray that is horizontal at the depth of the source in the ray diagrams.
Autoregulation of the Raf-1 serine/threonine kinase (1998)

The Raf-1 serine/threonine kinase is a key protein involved in the transmission of many growth and developmental signals. In this report, we show that autoinhibition mediated by the noncatalytic, N-terminal regulatory region of Raf-1 is an important mechanism regulating Raf-1 function. The inhibition of the regulatory region occurs, at least in part, through binding interactions involving the cysteine-rich domain. Events that disrupt this autoinhibition, such as mutation of the cysteine-rich domain or a mutation mimicking an activating phosphorylation event (Y340D), alleviate the repression of the regulatory region and increase Raf-1 activity. Based on the striking similarites between the autoregulation of the serine/threonine kinases protein kinase C, Byr2, and Raf-1, we propose that relief of autorepression and activation at the plasma membrane is an evolutionarily conserved mechanism of kinase regulation.
BRCA1 maps proximal to D17S579 on chromosome 17q21 by genetic analysis. (1993)

Previous studies have demonstrated linkage between early-onset breast cancer and ovarian cancer and genetic markers on chromosome 17q21. These markers define the location of a gene (BRCA1) which appears to be inherited as an autosomal dominant susceptibility allele. We analyzed five families with multiple affected individuals for evidence of linkage to the BRCA1 region. Two of the five families appear to be linked to BRCA1. One apparently linked family contains critical recombinants, suggesting that the gene is proximal to the marker D17S579 (Mfd188). These findings are consistent with the maximum-likelihood position estimated by the Breast Cancer Linkage Consortium and with recombination events detected in other linked families. Linkage analysis was greatly aided by PCR-based analysis of paraffin-embedded normal breast tissue from deceased family members, demonstrating the feasibility and importance of this approach. One of the two families with evidence of linkage between breast cancer and genetic markers flanking BRCA1 represents the first such family of African-American descent to be reported in detail.
Looking To Understand: The Coupling Between Speakers' and Listeners' Eye Movements and Its Relationship to Discourse Comprehension (2005)

We investigated the coupling between a speaker's and a listener's eye movements. Some participants talked extemporaneously about a television show whose cast members they were viewing on a screen in front of them. Later, other participants listened to these monologues while viewing the same screen. Eye movements were recorded for all speakers and listeners. According to cross-recurrence analysis, a listener's eye movements most closely matched a speaker's eye movements at a delay of 2 sec. Indeed, the more closely a listener's eye movements were coupled with a speaker's, the better the listener did on a comprehension test. In a second experiment, low-level visual cues were used to manipulate the listeners' eye movements, and these, in turn, influenced their latencies to comprehension questions. Just as eye movements reflect the mental state of an individual, the coupling between a speaker's and a listener's eye movements reflects the success of their communication.
Collaboration of IMS and SDN to enable new ICT service creation (2014)

Under the OTT threat, a telecom call-based ICT integration approach is studied to alleviate the revenue shrinkage. The CT-initiated IT services are thereby proposed to maintain existing telecom call service while adding OTT-like communication features on Internet. To do this, an IMS-based ICT service infrastructure is developed and the OpenFlow Controller is incorporated. Under such infrastructure the IMS call can correlate with the OpenFlow Controller and enable new ICT service creation and service control.

A Dominant Role of the Juxtamembrane Region of the TrkA Nerve Growth Factor Receptor during Neuronal Cell Differentiation (1997)

All receptor tyrosine kinases share a common intracellular signaling machinery, including ras activation, whereas cellular responses vary from mitogenesis to cell differentiation. To investigate the structural basis for receptor tyrosine kinase action for nerve growth factor, the juxtamembrane region of TrkA was transferred to a corresponding region of the epidermal growth factor (EGF) receptor. The resulting chimeric receptor contains an additional Shc site, Tyr490, in the juxtamembrane region. In transfected PC12 cell lines, neuronal differentiation was observed with EGF treatment, as evidenced by increased neurite extension. The action of the chimeric receptor was correlated with prolonged activation of MAP kinases and a 3-4-fold increase in phosphatidylinositol 3-kinase activity. The effect of the juxtamembrane chimera was dependent upon the Shc site at Tyr490, because expression of a chimeric receptor containing a Y490F mutation resulted in a complete loss of neuritogenesis by EGF treatment. These findings indicate that the juxtamembrane region of the TrkA receptor serves as a key functional domain that can confer a dominant effect upon neuronal differentiation.
Nickel-Catalyzed Site-Selective C–H Bond Difluoroalkylation of 8-Aminoquinolines on the C5-Position (2016)

A simple and efficient protocol for nickel-catalyzed regioselective C-H bond difluoroalkylation of 8-aminoquinoline scaffolds with functionalized difluoromethyl bromides was developed. The reaction has broad substrate scope and provides a facile and useful access to the corresponding C5-functionalized difluoromethylated quinolines in good to excellent yields.
Polyamines induce precocious development in rats. Possible interaction with growth factors (1989)

The study reports the effects of daily subcutaneous injections of the biogenic polyamines putrescine, spermidine and spermine (10 mg/kg each) given for a short postnatal period, on growth and development of rats. Polyamine treatment, while only slightly enhancing normal body weight gain, prevented the weight loss caused by surgical injury of 5-day-old animals. The treatment resulted in earlier eyelid and ear opening and in earlier maturation of righting and gripping responses. Increased number of neurons in the superior cervical ganglion that is caused by polyamine treatment, could not be prevented by castration of newborn rats, thus excluding the testes as a site through which polyamines may exert their action. An apparent increase in immunohistochemically detectable nerve growth factor was evident in iris and submaxillary salivary gland of polyamine-treated animals, but no change in epidermal growth factor immunohistochemistry was detected in the salivary gland. We conclude: (1) treatment of newborn rats with polyamines can accelerate somatic and neurobehavioral development; (2) further studies are required in order to verify and quantitate the effects of polyamines on growth factors, and (3) the results imply that exogenous polyamines may exert their growth-promoting effects on a number of cell types when these cells experience periods of polyamine dependence.
Dynamic Modeling of Weld Bead Geometry Features in Thick Plate GMAW Based on Machine Vision and Learning (2020)

Weld bead geometry features (WBGFs) such as the bead width, height, area, and center of gravity are the common factors for weighing welding quality control. The effective modeling of these WBGFs contributes to implementing timely decision making of welding process parameters to improve welding quality and enhance automatic levels. In this work, a dynamic modeling method of WBGFs is presented based on machine vision and learning in multipass gas metal arc welding (GMAW) with typical joints. A laser vision sensing system is used to detect weld seam profiles (WSPs) during the GMAW process. A novel WSP extraction method is proposed using scale-invariant feature transform and machine learning. The feature points of the extracted WSP, namely the boundary points of the weld beads, are identified with slope mutation detection and number supervision. In order to stabilize the modeling process, a fault detection and diagnosis method is implemented with cubic exponential smoothing, and the diagnostic accuracy is within 1.50 pixels. A linear interpolation method is presented to implement sub pixel discrimination of the weld bead before modeling WBGFs. With the effective feature points and the extracted WSP, a scheme of modeling the area, center of gravity, and all-position width and height of the weld bead is presented. Experimental results show that the proposed method in this work adapts to the variable features of the weld beads in thick plate GMAW with T-joints and butt/lap joints. This work can provide more evidence to control the weld formation in a thick plate GMAW in real time.
What's in Design Rationale? (1991)

A few representations have been used for capturing design rationale. To understand their scope and adequacy, we need to know how to evaluate them. In this article, we develop a framework for evaluating the expressive adequacy of design rationale representations. This framework is built by progressively differentiating the elements of design rationale that, when made explicit, support an increasing number of the design tasks. Using this framework, we present and assess DRL (decision representation language), a language for representing rationales that we believe is the most expressive of the existing representations. We also use the framework to assess the expressiveness of other design rationale representations and compare them to DRL. We conclude by pointing out the need for articulating other dimensions along which to evaluate design rationale representations.

Image formation in holographic tomography (2008)

Tomography has been applied to holographic imaging systems recently to improve the 3D imaging performance. However, there are two distinct ways to achieve this: either by rotation of the object or by rotation of the illumination beam. We provide a transfer function analysis to distinguish between these two techniques and to predict the 3D imaging performance in holographic tomography when diffraction effects are considered. The results show that the configuration of rotating the illumination beam in one direction while fixing the sample leads to different 3D imaging performance as compared to the configuration of rotating the sample. The spatial frequency cutoff is nonisotropic in the case of rotating the illumination, and a curved line of singularity is observed. Rotating of the sample, on the contrary, has more symmetry in spatial frequency coverage but has a single point of singularity. The 3D transfer function derived can be used for 3D image reconstruction.
3D imaging system based on FMCW millimeter wave radar (2006)

3D radar imaging systems are highly requested for use in guidance system for aircraft landing and shipping navigation. These systems usually work in difficult weather conditions such as fog, snow, dust. Use of 3-mm wavelength FMCW radar allows getting images at distances up to 1000m with high spatial resolution.
Distinction of winter road surface conditions using road surveillance camera (2012)

To prevent traffic accident, recognizing dangerous road surface conditions such as puddle and freezing are very important issue. Several methods to distinguish road surface condition have been suggested so far. However, there are only a few proposed methods for at night-time. In these systems, it needs special expensive equipment such as camera with polarizing lens, infrared detector or laser radar. Therefore, in this paper, we present a distinction method of road surface conditions of wet or snow by using only visible road surveillance camera at daytime and night-time. So, this system does not use special equipment. As a result, we are able to distinguish road surface condition with high accuracy at both daytime and night-time such as wet or snow.
Characterization of the DNA polymerases induced by a group of herpes simplex virus type I variants selected for growth in the presence of phosphonoformic acid. (1982)

Five independently derived variants of a herpes simplex virus type I (HSV-1) strain were plaque purified from a virus population passaged in 1 mM phosphonoformic acid (PFA). The DNA polymerase induced by the parent and PFA-resistant viruses were purified and characterized. No differences were observed among the enzymes with respect to their chromatographic properties, specific activities, or polypeptides resolved by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The variant enzymes exhibited levels of PFA resistance which ranged from 15- to 25-fold. Resistance to PFA was always associated with a similar degree of resistance to its congener phosphonoacetic acid, but cross-resistance to beta-phenylphosphonoacetic acid was only seen with two of the five variant enzymes. PFA and pyrophosphate were mutually competitive in PPi exchange reactions, but in DNA synthetic reactions the levels of resistance to PFA and PPi were not equal. The apparent affinities of the enzymes for Mg2+ did parallel their affinities for PFA. Km values of dNTPs were about 2-fold higher than the parent virus enzyme for all of the variant enzymes except one which was 4-fold higher. The processivity of polymerization was apparently unaffected by the enzyme changes related to PFA resistance although one variant enzyme had a lower value. Resistance among the variant enzymes to the triphosphates of 9-(2-hydroxyethoxymethyl)guanine and 2',3'-dideoxyguanosine was directly related to the level of resistance to PFA. The data presented here indicated that (i) PFA resistance may result from several types of active site alterations, since the PFA-resistant enzymes were of three kinetically distinct types. Also, additional enzyme alterations, probably unrelated to PFA resistance, were detected in one enzyme. (ii) PFA and PPi possess some different binding determinants within the active center of herpes simplex virus type I DNA polymerase. (iii) PFA and the triphosphates of 9-(2-hydroxyethoxymethyl)guanine and 2',3'-dideoxyguanosine may have a common ultimate inhibitory mechanism.
Comparison of inactivated Newcastle disease viral vaccines containing different emulsion adjuvants (1983)

Chickens inoculated with inactivated-virus Newcastle disease vaccines containing different emulsion adjuvants were challenge exposed with viscerotropic velogenic Newcastle disease virus. Adjuvant activity was evident in all of 9 vaccines containing mineral oil emulsion (OE), but was not evident in 2 vaccines which contained a metabolizable lipid emulsion (LE) adjuvant consisting of peanut oil, glycerol, and lecithin. Serologic responses of chickens inoculated with OE vaccines were 10- to 100-fold higher than those of chickens inoculated with LE vaccines. One of 106 chickens given OE vaccine, 12 of 24 given LE vaccine, and all of 24 nonvaccinated control chickens were clinically affected or died after challenge exposure. Five OE vaccines emulsified only by brief vigorous shaking had adjuvant activity similar to 4 OE vaccines emulsified by conventional homogenization.
Effect of cyclosporin on the activity of cytidine deaminase and adenosine deaminase in the serum and polymorphonuclear leukocytes of patients with rheumatoid arthritis. (1993)

Cytidine deaminase (CDA) and adenosine deaminase (ADA) were investigated in the serum and polymorphonuclear leukocytes (PMNLs) of healthy controls and ten patients with rheumatoid arthritis before and during cyclosporin therapy. CDA was significantly raised in the serum and decreased in the cells of patients. A dramatic increase (10-fold or more) in CDA activity was observed in the cells of some patients after only one month of cyclosporin therapy. Serum CDA significantly increased after three months' therapy. While the increase in serum CDA level during therapy was transient, the enzyme level in cells remained permanently raised, as shown in two patients evaluated for sixteen months. ADA in the serum of RA patients was somewhat higher as compared with healthy controls and remained almost unchanged during cyclosporin therapy. ADA activity in the cells also increased, but compared with the increase in CDA activity this increase was lower. Cyclosporin increased both CDA and ADA activities in PMNLs of RA patients. The dramatic increase in CDA observed in PMNLs of patients could be the cause of the transient increase in CDA in the serum. Further investigations will show to what extent this property of cyclosporin can reflect the immunoregulatory effect of this drug.
Survivorship and clinical evaluation of cementless, meniscal-bearing total ankle replacements. (1992)

A porous-coated, cementless, congruent-contact, meniscal-bearing total ankle replacement with a centrally placed trochlear groove and a cylindrical articulating axis representing the lateral talar curvature was developed and used clinically over a 10-year period. An initial clinical series of 40 ankle replacements involved the use of cobalt-chromium-molybdenum tibial and talar components with sintered-bead porous coating of 275-mum pore size and a shallow-sulcus trochlear groove with a central fixation fin for the talar onlay component. The congruent meniscal bearing, made of ultrahigh molecular-weight polyethylene (UHMWPe), was flat superiorly and matched the shallow-sulcus and cylindrical geometry inferiorly. Two bearings in two patients subluxed laterally and required revision within 2 years. The overall cumulative survival at the 10-year interval for this group using revision as an end point was 94.75%. The clinical results, using a strict ankle evaluation scoring scale, demonstrated 85% overall good to excellent results. Three patients required further treatment for intermalleolar exostoses, one patient required a debridement for infection, two ankles had medially subluxed bearings, eight ankles developed talar component subsidence, and two patients suffered from chronic reflex-sympathetic dystrophy. A second clinical series of 14 ankle replacements involved the use of polished titanium-nitride-coated titanium-6 aluminum-4 vanadium tibial and talar components with sintered-bead porous coating of 350-mum pore size and a deep-sulcus trochlear groove with two lateral fixation fins for the talar onlay component. The bearing element was similar to the initial series except that it had a deeper engagement in the trochlear groove to prevent subluxation.(ABSTRACT TRUNCATED AT 250 WORDS)
Incidental FDG PET Finding of Situs Inversus: A Case Report (2008)

Situs inversus totalis is a rare congenital condition in which the viscera are transposed as a mirror of normal arrangement. We present a 43-year-old man with nasopharyngeal carcinoma who had right neck mass for 3 months. In addition to hypermetabolic lesions in the nasopharynx and right neck, the FDG-PET scan for initial staging showed transposed heart, liver, spleen and stomach, suggestive of situs inversus totalis. The chest X-ray film and abdominal sonography showed compatible findings.
Preparation and characterization of hydroxyapatite/chitosan-gelatin network composite (2000)

A novel composite composed of hydroxyapatite (HA) and a network formed via cocrosslinking of chitosan and gelatin with glutaraldehyde was developed. Two preparation methods are described in detail. A porous material, with similar organic–inorganic constituents to that of natural bone, was made by a unique sol–gel method. The formation of the network in the presence of HA was characterized using IR analysis. The morphology of the composites was also examined using SEM. In addition, XRD was applied to estimate the change in the component crystal. The results indicate that the presence of HA does not retard the formation of the chitosan/gelatin network. On the other hand, the polymer matrix has hardly any influence on the high crystallinity of HA. © 2000 John Wiley & Sons, Inc. J Appl Polym Sci 77: 2929–2938, 2000

High Precision Mechanical Components for Soft X-ray Beamline: Engineering Goal and Testing Results (2007)

As the emittance of SR rings approaches the diffraction limit for soft x‐rays, one requires not only excellence in design and performance of the optical elements, but also precision and performance of mechanical components, such as mirror manipulators, monochromator scanners and exit slits. We will present simple but efficient solutions for the mechanical systems of this type, commonly encountered in soft x‐ray beamlines. These solutions have been implemented and their performance evaluated with test results from the spectromicroscopy beamline at the Canadian Light Source.
