Voting-based simultaneous tracking of multiple video objects (2005)

This paper proposes an automatic object tracking method based on both object segmentation and motion estimation for real-time content-oriented video applications. The method focuses on the issues of speed of execution and reliability in the presence of noise, coding artifacts, shadows, occlusion, and object split. Objects are tracked based on the similarity of their features in successive frames. This is done in three steps: feature extraction, object matching, and feature monitoring. In the first step, objects are segmented and their spatial and temporal features are computed. In the second step, using a nonlinear two-stage voting strategy, each object of the previous frame is matched with an object of the current frame creating a unique correspondence. In the third step, object changes, such objects occlusion or split, are monitored and object features are corrected. These new features are then used to update results of previous steps creating module interaction. The contributions in this paper are the real-time two-stage voting strategy, the monitoring of object changes to handle occlusion and object split, and the spatiotemporal adaptation of the tracking parameters. Experiments on indoor and outdoor video shots containing over 6000 frames, including deformable objects, multi-object occlusion, noise, and coding and object segmentation artifacts have demonstrated the reliability and real-time response of the proposed method.
Identification of intermediately virulent Rhodococcus equi isolates from pigs (1996)

We recently reported the existence of Rhodococcus equi isolates with at least three virulence levels, isolated from AIDS patients: virulent R. equi having 15- to 17-kDa antigens that kills mice with 10(6) cells, intermediately virulent R. equi having a 20-kDa antigen that kills mice with 10(7) cells, and avirulent R. equi that does not kill mice with 10(8) cells or more (S. Takai, Y. Imai, N. Fukunaga, Y. Uchida, K. Kamisawa, Y. Sasaki, S. Tsubaki, and T. Sekizaki, J. Infect. Dis. 172:1306-1311, 1995). Virulent R. equi having the 15- to 17-kDa antigens has been isolated frequently from horses and their environment, but the source of intermediately virulent R. equi having the 20-kDa antigen is poorly understood. There are many reports of the isolation of R. equi from the lymph nodes of pigs with and without lesions resembling those of tuberculosis. Therefore, we analyzed antigens of R. equi isolates from the submaxillary lymph nodes of pigs by immunoblotting with monoclonal antibodies against these virulence-associated antigens. Immunoblots of whole-cell antigen preparations of R. equi pig isolates revealed the presence of the 20-kDa antigen in almost all the pig isolates studied, and these isolates were intermediately virulent for mice. We also demonstrated that the expression of the 20-kDa antigen and its pathogenicity in mice were associated strongly with the presence of five large, distinct plasmids of 70 to 95 kb; two of the five plasmids from pig isolates were the same sizes as those from human isolates. These results suggest that R. equi having the 20-kDa antigen exists in the submaxillary lymph nodes of pigs and that the source of infection in some human cases might be associated with pigs and their environment.
A novel fungal GH30 xylanase with xylobiohydrolase auxiliary activity (2019)

Hereby, we reported the heterologous production and biochemical characterization of a novel fungal GH30 xylanase exhibiting endo- and exo-xylanase activity. To date, considering its novel catalytic properties, <i>Tt</i>Xyn30A shows differences with most characterized fungal and bacterial GH30 xylanases. The discovered xylobiohydrolase mode of action offers new insights into fungal enzymatic systems that are employed for the utilization of lignocellulosic biomass. The recombinant xylanase could be used for the production of X2 and UXOS from glucuronoxylan, which in turn would be utilized as prebiotics carrying manifold health benefits.
Les vicissitudes du divin au Mexique. L’évêque, le juge et le pulque (1991)

L’histoire mythique du Mexique précolombien raconte comment, lors de leur arrivée sur le plateau central, les nomades Mexica se heurtèrent aux Toltèques sédentaires, qui ne consentaient pas à pratiquer le sacrifice humain par arrachement de cœur. Après de vaines tentatives, le dieu nécromant Tezcatlipoca contraignit le prêtre-dieu toltèque Quetzal-coatl, le Sage, le Civilisateur, à abandonner le contrôle des régions convoitées en le poussant à s’enivrer avec du pulque par des manœuvres dolosi...
Theoretical limitations on the transmission of data from analog sources (1965)

Fundamental limitations on the performance of any type of communication system transmitting data from an analog source may be obtained by application of a theorem in Shannon's original paper on information theory. In order to transmit the output of an analog source to a sink with mean-squared error e or less, it is necessary to transmit information from source to sink at rates greater than some minimal rate <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">R(\epsilon)</tex> bits per second. If a channel of capacity <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">C</tex> bits per second is used, then in order for any communication system to be able to achieve <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">\epsilon</tex> mean-squared error or less with this channel it is necessary that <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">R(\epsilon) \leq C</tex> . This inequality can be used to determine the minimum mean-squared error obtainable for a given source-channel pair without discussing any particular communication system. As an example, the minimum mean-squared error is calculated for cases in which the analog source and additive channel noise are stationary, Gaussian processes. The performance of amplitude and angle modulation systems is compared to the theoretically ideal performance obtainable in some of these cases.
Intraluminal vapor bubble induced by excimer laser pulse causes microsecond arterial dilation and invagination leading to extensive wall damage in the rabbit. (1993)

In blood, each excimer laser pulse generated a fast-expanding and imploding vapor bubble. In vivo, the intraluminal vapor bubble produced microsecond dilation and invagination of the adjacent arterial segment, which induced dissections and extensive wall damage far beyond the penetration depth of 308-nm laser light (< 100 microns). This unique pattern of extensive wall damage observed in the rabbit might explain the mechanism of dissection observed in humans and might have an impact on the acute and chronic outcome after excimer laser coronary angioplasty.
Characterization of Four Novel <i>ras</i> -Like Genes Expressed in a Human Teratocarcinoma Cell Line (1990)

A mixed-oligonucleotide probe was used to identify four ras-like coding sequences in a human teratocarcinoma cDNA library. Two of these sequences resembled the rho genes, one was closely related to H-, K-, and N-ras, and one shared only the four sequence domains that define the ras gene superfamily. Homologs of the four genes were found in genomic DNA from a variety of mammals and from chicken. The genes were transcriptionally active in a range of human cell types.

Digital Blind Background Calibration of Imperfections in Time-Interleaved ADCs (2017)

This paper presents a digital blind background calibration technique of imperfections in time-interleaved analog-to-digital converters (TI-ADCs). The proposed technique directly operates on the statistics of the input signal to continuously estimate and eliminate the conversion errors resulted from offset, gain, and timing mismatch. Behavioral simulations are presented for a 4-channel 10-bit TI-ADC in order to verify the effectiveness of the proposed method. The signal-to-noise-and-distortion ratio (SNDR) is enhanced from 33.7 dB to more than 61 dB using the introduced calibration technique. This calibration method converges after roughly $4 \times 10^{6}$ conversions.
Changes in Soluble and Bound Peroxidase—IAA Oxidase During Tomato Fruit Development (1982)

ABSTRACT Soluble peroxidase activity increased dramatically during the early stages of tomato fruit development, reaching a maximum at the mature‐green stage. Ionically and covalently bound peroxidases were also observed, and the activities of these fractions increased steadily throughout fruit development. IAA (indoleacetic acid) oxidase activity was observed in both soluble and bound fractions and paralleled the peroxidase activity. Tissue homogenates from juvenile fruit caused an extended induction period in IAA oxidation reactions catalyzed by the purified tomato fruit peroxidase, suggesting the occurence of a high concentration of phenolic‐type auxin protectors in this tissue. As the fruit developed, tissue homogenates showed a reduction in the amount of auxin protectors as the IAA oxidizing capacity of the fruit increased.
Sialic acid prevents loss of large von Willebrand factor multimers by protecting against amino-terminal proteolytic cleavage (1988)

Removal of sialic acid from the von Willebrand factor (vWF) subunit exposes additional cleavage sites in the amino-terminal region that are associated with loss of large multimers. The extent of large multimer loss was evaluated by examining the sites of subunit cleavage of native and carbohydrate-modified vWF after treatment with trypsin, chymotrypsin, or plasmin. In the presence of proteinase inhibitors, purified vWF was treated with neuraminidase alone to remove 90% to 95% of the sialic acid or with neuraminidase and beta-galactosidase to remove the sialic acid and 45% to 50% of the D-galactose, with little or no loss of large multimers observed. Digestion of native vWF with trypsin produced the greatest loss of large multimers, while chymotrypsin produced less and plasmin produced the least. Large multimer loss was more extensive with each enzyme after carbohydrate modification of vWF. The extent and approximate location of subunit cleavage was determined by immunoblotting and monoclonal antibody epitope mapping. Trypsin, chymotrypsin, and plasmin were shown to produce both amino- and carboxyl-terminal fragments. The number, location, and relative quantities of carboxyl-terminal fragments produced were unchanged after carbohydrate modification. However, digestion of the amino-terminal region was considerably more extensive after carbohydrate modification as judged by a marked decrease or absence of the larger fragments seen when native vWF was digested, and by the appearance of new smaller molecular mass species. Therefore, the greater loss of large multimers that occurs after carbohydrate modification is likely to be the result of cleavages in the amino- terminal region of the molecule. By protecting the vWF subunit against amino-terminal cleavage, sialic acid inhibits the loss of large multimers.
Gain-switched Tm-doped fiber laser and amplifier with simultaneous mode-locked-like operation (2014)

We report on an all-fiber, fast gain-switched, Tm-doped fiber laser and amplifier system operating at 1994.4 nm. For 26 kHz repetition rate, stable 25-ns pulses with an energy of 0.28 mJ corresponding to a peak-power of 10.5 kW were achieved. Gain-switched pulses with simultaneous mode-locked-like operation were also demonstrated. The peak-power of the highest subpulses from the train was over 30 kW.
Rabi broadening of transient resonance Raman spectra of deoxy hemoglobin (1990)

The power-dependent behavior of the resonance Raman spectra of deoxy hemoglobin was studied by using ~30-psec laser pulses. The linewidth of a Raman active mode that is sensitive to porphyrin π-electron density, ν4, broadens asymmetrically as a function of laser fluence. Several possible origins of this phenomenon are examined, including the presence of a transient photoproduct and a nonlinear change in the resonance Raman scattering process through Rabi broadening. Our data are consistent with the second possibility and can be qualitatively modeled in simulations that use realistic values of T1 and T2 for the heme Soret electronic transition.
Sample Sizes Based on the Log-Rank Statistic in Complex Clinical Trials (1988)

The log-rank test is frequently used to compare survival curves. While sample size estimation for comparison of binomial proportions has been adapted to typical clinical trial conditions such as noncompliance, lag time, and staggered entry, the estimation of sample size when the log-rank statistic is to be used has not been generalized to these types of clinical trial conditions. This paper presents a method of estimating sample sizes for the comparison of survival curves by the log-rank statistic in the presence of unrestricted rates of noncompliance, lag time, and so forth. The method applies to stratified trials in which the above conditions may vary across the different strata, and does not assume proportional hazards. Power and duration, as well as sample sizes, can be estimated. The method also produces estimates for binomial proportions and the Tarone-Ware class of statistics.
Insertion and Characterization of the cry1Ia1 Gene in the Potato Cultivar Spunta for Resistance to Potato Tuber Moth (2010)

Potato tuber moth ( Phthorimaea operculella ) is a serious pest of potatoes in tropical and subtropical regions of the world, including South Africa. The cry1Ia1 gene (from Bacillus thuringiensis ) under the control of the 35S cauliflower mosaic virus promoter was transformed into the potato ( Solanum tuberosum ) cultivar Spunta to develop a cultivar with resistance to potato tuber moth for release in South Africa. Two transformation events, ‘SpuntaG2’ and ‘SpuntaG3’, were selected and subjected to extensive molecular analyses as required by the regulatory agencies of South Africa. Southern hybridization experiments indicated that ‘SpuntaG2’ and ‘SpuntaG3’ had one and three copies of the cry1Ia1 gene, respectively, and that the gene insertion was stable through multiple clonal generations. Furthermore, the sequence of the cry1Ia1 gene in ‘SpuntaG2’ was compared with the known sequence of the cry1Ia1 gene and found to be identical. Polymerase chain reaction (PCR) amplification using primers for plasmid “backbone” genes demonstrated that ‘SpuntaG2’ contained no backbone plasmid genes, whereas ‘SpuntaG3’ contained several backbone plasmid genes. Therefore, further analyses were limited to ‘SpuntaG2’, and event-specific primers were developed for this cultivar. Analysis of the left and right border regions in ‘SpuntaG2’ demonstrated that the insertion of the cry1Ia1 gene did not disrupt any functional genes nor did it create new open reading frames that encoded proteins with a significant match to the non-redundant sequence database queried by the BLASTP program. Enzyme-linked immunoabsorbent assays (ELISA) tests indicate that the cry1Ia1 gene was expressed at a mean concentration of 2.24 μg·g −1 fresh weight in leaf tissue and 0.12 μg·g −1 fresh weight in tubers. This study demonstrates the extensive molecular characterization that is necessary to apply for deregulation of a genetically modified crop and these data have been used in a regulatory package for the general release of ‘SpuntaG2’.
Effect of Rock Strength Criterion on the Predicted Onset of Sand Production (2005)

The variation of sanding onset prediction results with the selection of one or another rock strength criterion is investigated. In this paper, four commonly used rock strength criteria in sanding onset prediction and wellbore stability studies are presented. There are Mohr–Coulomb, Hoek–Brown, Drucker–Prager, and modified Lade criteria. In each of the criterion, there are two or more parameters involved. In the literature, a two-step procedure is applied to determine the parameters in the rock strength criterion. First, the Mohr–Coulomb parameters like cohesion So and internal friction angle ϕf, are regressed from the laboratory test data. Then, the parameters in other criteria are calculated using the regressed Mohr–Coulomb parameters. It is proposed that the best way to evaluate the parameters in a specific rock strength criterion is to perform direct regression of the laboratory test data using that criterion. Using this methodology, it is demonstrated that the effect of various rock strength criteria on sanding onset prediction is less dramatic than using the commonly used method. With this methodology, the uncertainties of the effect of rock strength criterion on sanding onset prediction are also reduced. Through this study, it is also demonstrated that a sanding onset prediction problem cannot be properly solved by adopting strength criteria that are not influenced by the intermediate principal stress if laboratory test data indicate rock failure is dependent on intermediate principal stress.

Liposomes Modified with Cyclic RGD Peptide for Tumor Targeting (2004)

Cyclic RGD peptide anchored sterically stabilized liposomes (RGD-SL) were investigated for selective and preferential presentation of carrier contents at angiogenic endothelial cells overexpressing alphavbeta3 integrins on and around tumor tissue and thus for assessing their targetabilty. Liposomes were prepared using distearoylphosphatidylcholine (DSPC), cholesterol and distearoylphosphatidylethanolamine-polyethyleneglycol-RGD peptide conjugate (DSPE-PEG-RGD) in a molar ratio 56:39:5. The control RAD peptide anchored sterically stabilized liposomes (RAD-SL) and liposome with 5 mol% PEG (SL) without peptide conjugate which had similar lipid composition were used for comparison. The average size of all liposome preparations prepared was approximately 105 nm and maximum drug entrapment was 10.5+/- 1.1%. In vitro endothelial cell binding of liposomes exhibited 7-fold higher binding of RGD-SL to HUVEC in comparison to the SL and RAD-SL. Spontaneous lung metastasis and angiogenesis assays show that RGD peptide anchored liposomes are significantly (p<0.01) effective in the prevention of lung metastasis and angiogenesis compared to free 5-FU, SL and RAD-SL. In therapeutic experiments, 5-FU, SL, RGD-SL and RAD-SL were administered intravenously on day 4 at the dose of 10 mg 5-FU/kg body weight to B16F10 tumor bearing BALB/c mice resulting in effective regression of tumors compared with free 5-FU, SL and RAD-SL. Results indicate that cyclic RGD peptide anchored sterically stabilized liposomes bearing 5-FU are significantly (p<0.01) active against primary tumor and metastasis than the non-targeted sterically stabilized liposomes and free drug. Thus cyclic RGD peptide anchored sterically stabilized liposomes hold potential of targeted cancer chemotherapeutics.
Treadmill training for patients with Parkinson's disease (2010)

Patients with Parkinson's disease who receive treadmill training are more likely to improve their impaired gait hypokinesia. However, the results must be interpreted with caution because there were variations between the trials in patient characteristics, the duration and amount of training, and types of treatment. Additionally, it is not known how long these improvements may last.
V2540 Oph (Nova Oph 2002): Large-Amplitude Slow Nova with Strong Post-Outburst Oscillations (2002)

V2540 Oph (Nova Oph 2002) is a classical nova discovered by Katsumi Haseda and Yuji Nakamura on 2002 January 24. The light curve of this nova shows strong post-outburst oscillations as were observed in V1178 Sco and V4361 Sgr. Accurate astrometry of the nova yeilded an upper limit of 21 mag for the nova precursor. In combination with the observed decline rate, We propose that the nova should have either a short orbital period or a high inclination. We suggest that V2540 Oph may be analogous to V2214 Oph, a presumed magnetic nova inside the period gap.
Chemically pumped iodine laser (1979)
