Video inpainting and implant via diversified temporal continuations (video demonstration) (2006)

This video program presents several video inpainting/implant mechanisms implemented under different types of videos with diversified temporal continuations. We use an improved image inpainting method to remove foreground objects. Another set of objects are implanted into the inpainted video. Detailed algorithms are presented in a paper in the 2006 ACM Multimedia conference.
Isolation of a prokaryotic plasmin receptor. Relationship to a plasminogen activator produced by the same micro-organism. (1991)

Plasminogen receptors have been identified on the surface of a number of prokaryotic and eukaryotic cells. A receptor demonstrating high affinity for plasmin with minimal reactivity with the native zymogen Glu-plasminogen has been identified on the surface of certain group A streptococci. In this study the group A streptococcal plasmin receptor has been solubilized and purified to homogeneity. The isolated protein was an Mr approximately 41,000 molecule which retained its ability to bind plasmin following solubilization and affinity purification on a column of enzymatically inactivated human plasmin. The isolated plasmin receptor was compared functionally, antigenically, and physicochemically to the secreted plasminogen activator, streptokinase, produced by the same organism. The Mr approximately 41,000 surface plasmin receptor was shown to be functionally and antigenically distinct from the Mr approximately 48,000 streptokinase molecule produced by the same strain and lacked any plasminogen activator activity. The streptokinase molecule produced by this strain was shown to be closely related to the plasminogen activator protein secreted by other group A and C streptococci. This study represents the first report of the isolation of a plasmin receptor, either prokaryotic or eukaryotic, with functional activity.
<title>Image Quality Effects In Optical Correlators</title> (1981)

Three aspects of image quality and their effects in an optical matched spatial filter correlator are described. These concern operation on: digitized imagery, data with low modulation and low space bandwidth product, and synthetic reference imagery. To address these practical problems, we employ: spatial filtering, edge enhancement, use of different apertures, photoreduced imagery, and digital preprocessed data. The first exuerimental data on optical matched spatial filter correlations with synthetic reference imagery and the first comparative data on digitally and optically processed multisensor image correlations are included. From these experiments, we find an optical weighted matched spatial filter correlator to be adequate for most multisensor data and that advanced digital preprocessing operators are necessary when presently available synthetic reference imagery is used.
Data transmission when the sampling frequency exceeds the Nyquist rate (1997)

We show that if a channel with a total spectral support of W Hz is sampled at a rate f/sub s/>2W Hz (exceeding the Nyquist condition), it is possible to find integers M, N such that only a certain subset, consisting of M members of the N integers, carries independent data which obey M/N/spl les/2W/f/sub s/. Not all integers M, N satisfying this inequality will work, and even for a working set of M and N, not every subset M of N integers will work. We derive the relation between M, N, f/sub s/, the spectral support of the channel, and the subset M of the N integers.
Demonstration of a Narrow Energy Spread,<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mo>∼</mml:mo><mml:mn>0.5</mml:mn><mml:mtext> </mml:mtext><mml:mtext> </mml:mtext><mml:mi>GeV</mml:mi></mml:math>Electron Beam from a Two-Stage Laser Wakefield Accelerator (2011)

Laser wakefield acceleration of electrons holds great promise for producing ultracompact stages of GeV scale, high-quality electron beams for applications such as x-ray free electron lasers and high-energy colliders. Ultrahigh intensity laser pulses can be self-guided by relativistic plasma waves (the wake) over tens of vacuum diffraction lengths, to give >1 GeV energy in centimeter-scale low density plasmas using ionization-induced injection to inject charge into the wake even at low densities. By restricting electron injection to a distinct short region, the injector stage, energetic electron beams (of the order of 100 MeV) with a relatively large energy spread are generated. Some of these electrons are then further accelerated by a second, longer accelerator stage, which increases their energy to ∼0.5 GeV while reducing the relative energy spread to <5% FWHM.
Case Study on Simultaneous Gasification of Black Liquor and Biomass in a Pulp Mill (1998)

One of the main limiting factors when a green field pulp mill intends to increase its production is the capacity of the Tomlinson boiler by which the cooking chemicals are recovered. Since a boiler of this kind has a service life of some thirty years and represents a substantial investment, it is not an easy decision to replace it for a minor production increase. This study takes a novel approach to the problem. The excess black liquor is assumed to be recovered in a black liquor gasifier, an emerging technology for alternative black liquor recovery. Black liquor gasification in itself has been studied considerably during the last decade. In this study it is combined with the gasification of biomass, i.e. bark and wood, which is already available at a pulp mill. The resulting hybrid energy system, with a gas turbine and a gas expander, offers interesting possibilities: good off-design performance and high efficiency with respect to the fuel quality.
A set of canine interrepeat sequence PCR markers for high-throughput genotyping (2000)

One hundred and sixteen interspersed repetitive DNA sequence (IRS)-PCR markers have been developed and characterized from Canis familiaris for high-throughput filter-based genotyping. We present a detailed analysis of markers produced by amplification using primers directed to the conserved regions of the C. familiaris short interspersed nuclear element (Can-SINE). The majority of IRS-PCR markers developed were moderately to highly polymorphic with mean heterozygosity (HET) and polymorphism information content (PIC) values of approximately 0.6. The HET value for 22.3% of the markers exceeded 0.7. We also demonstrate that sequence variation of Can-SINEs between breeds is significant and also represents a rich source of polymorphisms. Mapping of 73 of the markers to the existing integrated linkage-radiation hybrid map enriches the map as well as establishes the utility of the markers. The significance and utility of this new class of IRS-PCR Can-SINE-based markers for high-throughput genotyping is discussed. This method can also be extended to other species that are currently map-poor but have a sufficiently high density of SINEs to allow IRS-PCR.
Terahertz surface-wave resonant sensor with a metal hole array (2006)

A surface-wave sensor based on the resonant transmission characteristics of metal hole arrays is demonstrated in the terahertz (THz) region. Since the frequency of the transmission peak of a metal hole array, which corresponds to the resonant frequency of the surface waves, is particularly sensitive to the refractive index in the vicinity of the metal surface, a very small change in the substances attached to the surface can be detected by monitoring the transmission spectrum. By attaching a layer of substance (thickness t < 5 microm) much thinner than the wavelength of the THz wave (lambda(THz) = 1 mm at 0.3 THz) to the surface of a metal hole array, we demonstrated that the existence of such a small amount of substance can be detected more easily than without the metal hole array. This demonstration of THz sensing with metal hole arrays indicates the possibility of realizing THz surface-wave sensors for biochemical molecules in the THz region.
Physical Cell Identifier assignment in LTE-advanced networks (2012)

In this article, a fully distributed mechanism of Physical Cell Identifier (PCI) assignment within LTE-A networks, where there are more than 504 femtocells deployed under one macrocell, is analysed. We propose a technique that can assign collision-free PCIs and work out any confusion event that may occur in the macrocell. Simulation results based on implementation of the algorithm proposed are presented and discussed. It is shown that the algorithm is capable of solving confusion events in dense femtocell scenarios.
Chemical-looping with oxygen uncoupling using combined Mn-Fe oxides, testing in batch fluidized bed (2011)

Chemical-looping with oxygen uncoupling (CLOU) has been studied with gaseous and solid fuel in a small fluidized bed batch reactor, using new Fe-Mn-based oxygen carriers. CLOU is a development of chemical-looping combustion, using oxygen carriers with the ability to release oxygen, which can react directly with the fuel. The carbon dioxide from the combustion is inherently obtained as separated from the rest of the flue gases. In this work manganese is combined with iron oxides, giving new bimetallic oxide compounds with different thermodynamic properties compared to pure manganese oxides. Four different combinations of iron manganese oxide have been examined by decomposition in N2 and also reaction with methane and syn-gas. F3, a material with a molar ratio of Fe:Mn of 2:1, showed the best behaviour in terms of its release of oxygen, take up of oxygen, fluidizability and methane conversion. Therefore, F3 was also tested with solid fuel using inert fludization gas, N2. The char particles effectively remove oxygen released as it is converted to CO2. Thus, CO2 will represent the oxygen release. The tests show that the particles release oxygen corresponding to approximately 0.5% of their mass. Moreover, a test where steam was added in the fluidization gas showed high gas conversion, with essentially no unconverted gas. Thus, the tests indicate that the F3 particles, if used in chemical-looping of solid fuels, could contribute both to faster fuel conversion and to higher conversion of gas, as compared to a normal oxygen carrier that does not release oxygen.
Performance of single-turn film heads (1973)

This paper begins with a review of previously published work on film recording heads and then reports on write-read experiments with single-turn film heads at a medium velocity of 40 m/s (1575 in/s). A typical film head is compared to a conventional ferrite head with regard to readback pulse shape, transition-density response, and efficiency. The results are in agreement with theoretical predictions.
Shielding Efficiency of a Fabric Based on Amorphous Glass-Covered Magnetic Microwires to Radiation Emitted by a Mobile Phone in 2G and 3G Communication Technologies (2017)

Abstract A dual band mobile phone model was used to check the shielding properties of an amorphous ferromagnetic textile against the radiation emitted by the handset. Two frequencies belonging to the 2 nd and 3 rd generation of mobile emission technologies were used, 897 MHz and 1950 MHz. The specific absorption rate (SAR) of energy deposition in a human head phantom was measured in standardized conditions. The textile contained micrometric-diameter wires of a ferromagnetic mixture embedded in a thin glass coat and weaved in a specific way. A set of fabric orientations and configurations (layering) were provided in the experiment in order to achieve a better shielding to the phone’s radiation. Compared with the non-shielded handset, SAR deposited in the head while using the fabric-covered phone could be decreased up to 30 % of its initial value – in case of 2G technology and up to 24 % – in case of 3G technology. This type of material shows one of the highest shielding efficiencies of the electric-field component in near-field exposure conditions reported until now. A cubic curve of SAR decrease in depth of the head was revealed in both uncovered and covered handset, the effect of shielding being larger at the higher frequency.
Extracellular antigens of Moraxella bovis. (1976)

The extracellular antigens of 2 isolates of Moraxella bovis were isolated by ammonium sulfate precipitation of cell-free culture filtrate, purified by filtration and differentiated by immunodiffusion and immunoelectrophoretic techniques. The extracellular filtrate from rough types had 2 specific extracellular antigens in addition to those in the culture filtrate of smooth-type cells of the same isolate. The extracellular antigens produced by smooth-type cells were identical in all isolates of Moraxella bovis. The serotype-specific extracellular antigens of 2 isolates were serologically identical but were different from those of a 3rd isolate. The possibility of serotyping M bovis isolates, on the basis of their extracellular rough-type antigens, was suggested. Although both serotype-specific antigens were destroyed by trypsin treatment, 1 antigen was also heat-labile and partially destroyed by formalin treatment.
Microstructure and Spectroscopy of Lu<sub>2</sub>O<sub>3</sub>:Eu Prepared Using Various Synthesis Techniques (2004)

Nanocrystalline powders of Lu2O3:Eu with activator content varying between 0.2%-10% were prepared using four different methods of synthesis. The products differed in their microstructure and crystallites sizes. Combustion of Lu(NO3)3 with urea produced strongly agglomerated material, most probably with significantly non-uniform distribution of the Eu3+ dopant. Replacing urea with glycine for the combustion produced only slightly agglomerated, voluminous, fluffy powder. Applying the Pechini technique resulted in significantly agglomerated powder while the homogeneous precipitation of Lu(OH)3 with urea at 90 °C and its subsequent decomposition to Lu2O3 at 650 °C resulted in a powder of perfectly spherical particles with a uniform size of about 130 nm with very low agglomeration. The efficiency of X-ray excited luminescence of our nanocrystalline Lu2O3:5%Eu was compared to that of the commercial microcrystalline Gd2O2S:Eu. It was found that the commercial phosphor performed four times more efficiently than our nanocrystalline powder. We consider this to be rather encouraging as the fabrication of our powder is not optimized yet. It seems that Lu2O3:Eu, even in nanocrystalline form, can perform much more efficiently which would make it a promising X-ray phosphor.
Enhancing group recommendation by incorporating social relationship interactions (2010)

Group recommendation, which makes recommendations to a group of users instead of individuals, has become increasingly important in both the workspace and people's social activities, such as brainstorming sessions for coworkers and social TV for family members or friends. Group recommendation is a challenging problem due to the dynamics of group memberships and diversity of group members. Previous work focused mainly on the content interests of group members and ignored the social characteristics within a group, resulting in suboptimal group recommendation performance.In this work, we propose a group recommendation method that utilizes both social and content interests of group members. We study the key characteristics of groups and propose (1) a group consensus function that captures the social, expertise, and interest dissimilarity among multiple group members; and (2) a generic framework that automatically analyzes group characteristics and constructs the corresponding group consensus function. Detailed user studies of diverse groups demonstrate the effectiveness of the proposed techniques, and the importance of incorporating both social and content interests in group recommender systems.
SPECTROPHOTOMETRIC STUDY OF BRUISES ON WHOLE, 'RED DELICIOUS' APPLES (1990)

ABSTRACT Spectrophotometric studies were conducted to investigate the diffuse reflectance in the 400 to 1000 nanometer (nm) wavelength region for bruised and nonbruised areas on whole 'Red Delicious' apples. Reflectance single-wavelength, two-wavelength ratio, two-wavelength difference, normalized two-wavelength difference, and reflectance derivative models were developed from the reflectance spectra data. Linear regression analysis was used to identify the wavelengths most related to bruise identification for each model. Resulting models were tested using 200 measurements from 50 apples of which 100 were bruised and 100 were nonbruised areas. The single wavelength model had the lowest correlation (r^ = 0.46) and the worst classification performance (50% misclassified) while the ratio, normalized difference, and the derivative models had the best performance (r^ = 0.79 - 0.81), with only 2.5 - 3.5% of the fruit misclassified.
Faster healing and less pain in skin biopsy sites treated with an occlusive dressing (1991)

• We prospectively studied 174 patients on whom 226 unsutured parallel incisional (shave) and 3-mm punch skin biopsies were performed. Two wound-care programs, occlusive dressing therapy and conventional therapy, were compared. The biopsy sites were evaluated after 1 or 2 weeks for healing, pain, and infection. We found that healing was unrelated to the indication for biopsy or the patients' age, gender, or race. Occlusive dressing therapy—treated shave biopsy sites were 3.83 times more likely to be healed than those treated with conventional therapy. Regardless of the treatment method, a facial shave biopsy site was 3.6 times more likely to be healed than a biopsy site in other locations. No punch biopsy site had healed after 1 week. At 2 weeks, only 7% and 36% of conventional therapy— and occlusive dressing therapy—treated punch biopsy sites, respectively, had healed. Pain at the biopsy site was six times more common in both shave and punch biopsy sites treated with conventional therapy. The absence of pain with occlusive dressing therapy was significant for both types of biopsy. One punch biopsy site treated with conventional therapy became infected, and one treated with occlusive dressing therapy was suspected of being infected. Forty patients, who had biopsy sites treated with both therapies, preferred occlusive dressing therapy over conventional therapy by a ratio of 3:1 because of ease of wound care and lack of pain. We conclude that occlusive dressing therapy may be the wound management of choice for shave biopsy sites. Since punch biopsy sites do not heal readily, it may be more appropriate to suture them, at least until therapies are developed that more effectively speed their healing.

Evidence for the location of high mobility group protein T in the internucleosomal linker regions of trout testis chromatin. (1979)

Antibodies against the trout testis non"histone chromosomal protein, high mobility group protein T (HMG-T), have been elicited in goats. The antiserum was shown to be specific for HMG-T and did not cross-react with histone 1 or with the other two trout testis HMG proteins, H6 and ubiquitin. Purified anti-HMG-T IgG was used to determine the location of HMG-T within chromatin subunits separated on sucrose gradients. Binding of fluorescent labeled anti-HMG-T to these subunits clearly supports the notion that this protein is associated not with the nucleosome core but rather with the internucleosomal linker regions, and previously suggested (Levy W., B., Wong, N.C.W., and Dixon, G. H. (1977) Proc. Natl. Acad. Sci. U.S.A. 74, 2810-2814).
Surface acoustic wave convolver using multiple waveguide (1987)

Abstract A new elastic convolver is proposed in which a nonlinear interaction of surface acoustic waves (SAW) on multiple waveguides is used. Theoretical and experimental investigations are carried out. When two SAWs with angular frequency of ω and wavenumber of β, and with ω and‐β propagate in opposite directions on N waveguides, the parametric mixing phenomenon generates a SAW with a sum frequency traveling in the direction normal to the waveguide. The generation efficiency increases: (i) when the width of one of the waveguides is one‐half the wavelength of the sum frequency SAW; (ii) with the number N of the waveguides with the maximum occurring at N = 8 ∼ 10; and (iii) with the larger velocity difference (Δ V/V ). Generation of the sum frequency SAW is possible only with the guided mode of SAW. The present convolver can be matched easily with the external circuit, because the convolution output is extracted with an interdigital electrode (IDT).
Microarray-Based Response Prediction in Esophageal Adenocarcinoma (2009)

There were significant differences in the gene profile between patients with adenocarcinoma of the esophagus responding to neoadjuvant chemotherapy compared with nonresponding patients. This suggests that it could be possible to characterize patients responding to chemotherapy even before starting the treatment using customized microarray analysis.
Interplay between pre-mRNA splicing and microRNA biogenesis within the supraspliceosome (2014)

MicroRNAs (miRNAs) are central regulators of gene expression, and a large fraction of them are encoded in introns of RNA polymerase II transcripts. Thus, the biogenesis of intronic miRNAs by the microprocessor and the splicing of their host introns by the spliceosome require coordination between these processing events. This cross-talk is addressed here. We show that key microprocessor proteins Drosha and DGCR8 as well as pre-miRNAs cosediment with supraspliceosomes, where nuclear posttranscriptional processing is executed. We further show that inhibition of splicing increases miRNAs expression, whereas knock-down of Drosha increases splicing. We identified a novel splicing event in intron 13 of MCM7, where the miR-106b-25 cluster is located. The unique splice isoform includes a hosted pre-miRNA in the extended exon and excludes its processing. This indicates a possible mechanism of altering the levels of different miRNAs originating from the same transcript. Altogether, our study indicates interplay between the splicing and microprocessor machineries within a supraspliceosome context.
Sign Detection in Residue Number Systems (1969)

This paper is concerned with the sign detection problem in residue number systems. The proposed solution is applicable only to nonredundant systems. It is shown that under rather general conditions an explicit, closed formula for the sign function can be obtained. In a special case, when one of the moduli is 2, the sign function becomes an EXCLUSIVE-OR function. A sign detection algorithm is proposed and methods of implementing the algorithm are presented.
