Long-term tracking method on ground moving target of UAV (2014)

The 7th IARC (international aerial robot competition) focus on a long-term and real-time tracking of ground moving target for UAV (unmanned aerial vehicle). This paper proposes a tracking method using Camshift algorithm with color and edge features fusion, which will apply a Phash target detection algorithm basing on perceptual hash algorithm. Supposing targets are severely obscured or disappear from view, which will lead tracking failure, whereas targets can be detected and obtained again using the method. Experimental results demonstrate that this method can provide a long-term and real-time tracking of ground moving target, which processes both robustness and computational efficiency.

Prospective randomized investigation of topical anesthesia during unilateral laparoscopic ovariectomy in horses (2019)

Topical anesthesia application to the ovary could provide an alternative to laparoscopic needle use, reducing the risk of inadvertent trauma to the pedicle or other visceral organs during laparoscopic ovariectomy.
“Less, Worse and More Expensive: Childcare in an Era of Deficit Reduction” (1999)

Despite the enormous need of children, mothers, families and employers for childcare, its provision is worsening in Canada in the 1990s. Although more is known about the positive impacts of high quality early childhood care and education on child development than ever before, few children have access to high quality early childhood care. Although women's increasing participation in paid work means there is a greater need for non-family care, childcare service expansion is stalling. Childcare is one of the earliest casualties of a rapidly restructuring Canadian welfare state. This article considers the past and current place of childcare, highlighting what is happening in the 1990s and showing how childcare arrangements illuminate the assumptions of the Canadian welfare state. It argues that women's equality is compromised when services for children are treated as either a private family responsibility or a matter for the market. Citizenship and entitlement are circumscribed when childcare needs are delegated to such arrangements.
Influence of the Dominant White/KIT Genotypes on the Reproductive Organs of Pigs (2006)

Based on earlier studies with mice and pigs, the possible pleiotropic effects of the individual porcine Dominant White/KIT genotypes on the size, histological parameters, and surface features of the ovaries; on the size, histological characteristics, and volume of the testes; and on the occurrence of abnormal epididymal sperm cells were studied in two F2 generations of an intercross between Hampshire boars and Hungarian Large White sows. The KIT genotypes were determined by a PCR-RFLP method. The ovarian diameters of gilts of various KIT genotypes did not differ significantly (P=0.292), and the II pigs had the smallest diameters. The proportion of the investigated follicular types among the different KIT genotypes did not differ significantly (P=0.329-0.919), and the highest numbers of degenerated and atretic follicles were found in the ovaries of II genotype pigs, which also exhibited the highest proportion of primary follicles. The testis volume in the II homozygote white genotype boars (249.5 cm(3)) was significantly (P<0.01) larger than in the Ii (205.4 cm(3)) and ii (197.5 cm(3)) boars. Bodyweight and age significantly (P<0.01) affected testicular volume. KIT genotypes had no profound effect on the proportion of the various epididymal sperm abnormalities, and ii type boars showed the highest (nonsignificant) numbers of primary abnormalities. The changes in abnormal sperm cell frequency were linear to the changes in bodyweight and testis volume. We were unable to demonstrate disadvantageous effects of the KIT genotypes on the investigated ovarian, testicular, and epididymal sperm characteristics. Therefore the reproductive traits of white colored pigs examined in this study are no worse than those of pigmented breeds.

The Lobatamides, Novel Cytotoxic Macrolides from Southwestern Pacific Tunicates (1998)

Novel macrolides, lobatamides A−F (1−6), have been isolated from shallow water Australian collections of Aplidium lobatum, from a deep water collection of Aplidium sp., and from an unidentified Philippine ascidian. Full details of the isolation and structure elucidation of 1−6 are provided herein, along with results and analyses of the testing of lobatamides A−D (1−4) in the NCI human tumor 60 cell-line screen. The lobatamides share a common core structure with the recently described salicylihalamides, which were isolated from a Haliclona sp. sponge. COMPARE analyses of the mean-graph differential cytotoxicity profiles of the lobatamides and the salicylihalamides showed high correlations with each other but not with members of the NCI's standard agents database. These compounds, therefore, appear to comprise a new mechanistic class, meriting further antitumor investigations.

A Vision-Based Automated Guided Vehicle System with Marker Recognition for Indoor Use (2013)

We propose an intelligent vision-based Automated Guided Vehicle (AGV) system using fiduciary markers. In this paper, we explore a low-cost, efficient vehicle guiding method using a consumer grade web camera and fiduciary markers. In the proposed method, the system uses fiduciary markers with a capital letter or triangle indicating direction in it. The markers are very easy to produce, manipulate, and maintain. The marker information is used to guide a vehicle. We use hue and saturation values in the image to extract marker candidates. When the known size fiduciary marker is detected by using a bird's eye view and Hough transform, the positional relation between the marker and the vehicle can be calculated. To recognize the character in the marker, a distance transform is used. The probability of feature matching was calculated by using a distance transform, and a feature having high probability is selected as a captured marker. Four directional signals and 10 alphabet features are defined and used as markers. A 98.87% recognition rate was achieved in the testing phase. The experimental results with the fiduciary marker show that the proposed method is a solution for an indoor AGV system.
Antibacterial Polyelectrolyte Micelles for Coating Stainless Steel (2012)

In this study, we report on the original synthesis and characterization of novel antimicrobial coatings for stainless steel by alternating the deposition of aqueous solutions of positively charged polyelectrolyte micelles doped with silver-based nanoparticles with a polyanion. The micelles are formed by electrostatic interaction between two oppositely charged polymers: a polycation bearing 3,4-dihydroxyphenylalanine units (DOPA, a major component of natural adhesives) and a polyanion (poly(styrene sulfonate), PSS) without using any block copolymer. DOPA units are exploited for their well-known ability to anchor to stainless steel and to form and stabilize biocidal silver nanoparticles (Ag(0)). The chlorine counteranion of the polycation forms and stabilizes biocidal silver chloride nanoparticles (AgCl). We demonstrate that two layers of micelles (alternated by PSS) doped with silver particles are enough to impart to the surface strong antibacterial activity against gram-negative E. coli. Moreover, micelles that are reservoirs of biocidal Ag(+) can be easily reactivated after depletion. This novel water-based approach is convenient, simple, and attractive for industrial applications.
G/t Optimization of Wideband, Prime Focus Paraboloids (2000)

A review is given on a study of the gain versus antenna temperature optimisation of small, low cost, prime focus parabolic antennas. Especially the choice of feed system plays an important role in this optimisation. From this study it is concluded that a log periodic dipole antenna is a favourable option. Details and numerical results from simulations for this option are presented. These details show that with a proper construction the antenna gain can be considerably higher then presented in previous reports. Furthermore it is shown that an optimal G/T ratio of the investigated antenna system for astronomy applications needs a different f/d ratio for the parabolic reflector compared to a system for terrestrial use. The results from this study are directly applicable to the One Hectare Telescope as is proposed by the SETI Institute.
Spatial and temporal stability of tissue induced aberration (2005)

Real-time adaptive imaging systems employ nearfield phase correction techniques, which are desired because of their computational simplicity and compatibility with current imaging system architectures. Aberrator stability is essential to adaptive imaging because it defines the spatial and temporal limits for which the near-field phase estimates are valid. In this study, the spatial and temporal stability of clinical aberrations is measured in breast, liver, and thyroid tissue and discussed in relation to real-time adaptive imaging. Azimuthal isoplanatic patch sizes of 1.1, 0.44, and 1.0 mm were measured for breast, liver, and thyroid tissue, respectively, using a 70% correlation limit. Axial isoplanatic patch sizes were 2.0, 1.2, and 2.9 mm for the same tissue, respectively. Temporal stability was determined to be greater than 1.5 seconds for breast and thyroid tissue, and 1.2 seconds in the liver. The effects of noise, motion, and target non-uniformity on aberrator stability are characterized with simulations and experiments in tissue mimicking phantoms.

Facile Modifications at the C4 Position of Pyrimidine Nucleosides via In Situ Amide Activation with 1H‐Benzotriazol‐1‐yloxy‐tris(dimethyl‐amino)phosphonium Hexafluorophosphate (2019)

Two approaches for C4 modifications of silyl-protected thymidine, 2'-deoxyuridine, and 3'-azido-2',3'-dideoxythymidine (AZT) are described. In both, nucleoside amide activation with 1H-benzotriazol-1-yloxy-tris(dimethylamino)phosphonium hexafluorophosphate (BOP) and DBU yields O<sup>4</sup> -(benzotriazol-1-yl) derivatives. These in situ-formed intermediates are reacted with various nucleophiles, resulting in C4 modifications. In the two-step, one-pot approach, the O<sup>4</sup> -(benzotriazol-1-yl) nucleoside intermediates are initially produced by reactions of the nucleosides with BOP and DBU in THF. This step is fast and typically complete within 30 min. Subsequently, the O<sup>4</sup> -(benzotriazol-1-yl) derivatives are reacted with nucleophiles, such as aliphatic and aromatic amines, thiols, and alcohols, under appropriate conditions. Workup, isolation, and purification lead to the desired C4-modified pyrimidine nucleosides in good to excellent yields. In the one-step approach, the nucleosides are reacted with BOP and DBU, in the presence of the nucleophile (only aliphatic and aromatic amines, and thiols have been tested). Where comparisons are possible, the one-step approach is generally superior. © 2019 by John Wiley & Sons, Inc.
JavaCard-from hype to reality (1999)

In this final of three related articles about smart card technology, the authors discuss the JavaCard, a much-hyped technology that is finally taking off as a multiapplication smart card. The main reason for the hype is JavaCard's potential. Not only would it let all Java programmers develop smart card code, but such code could be downloaded to cards that have already been issued to customers.
Plasminogen Activator Inhibitor 1: Physiological and Pathophysiological Roles (2002)

Plasminogen activator inhibitor 1 (PAI-1) inhibits plasminogen activators (u-PA and t-PA) by forming stable complexes endocytosed via a low-density lipoprotein receptor superfamily member-dependent mechanism. PAI-1 circulates actively in plasma and latently in platelets but is also secreted and deposited into the matrix by several cells, where it participates in tissue repair processes.
Diagnostic test pattern generation for analog circuits using hierarchical models (1999)

In this paper we propose a novel fault-based transient test generation methodology for locating faults in hierarchical nonlinear analog circuits. A heuristic optimization algorithm generates test stimuli that can distinguish fault-effects based on voltage measurements at observable circuit nodes. hierarchical fault dictionaries are generated for the purpose of fault location. The cost of simulation during dictionary construction is significantly reduced as the proposed method uses hierarchical behavioral modeling of circuits and fault dropping techniques. The proposed algorithms can also be used to generate tests for fault detection. A complete diagnostic test generation system has been implemented and tested successfully.
<title>Fourier transform evaluation of interference patterns: demodulation and sign ambiguity</title> (1992)

The Fourier-transform method determines the interference phase distribution from an interference pattern. If evaluating only a single pattern, the sign remains unknown. Methods for interactive sign correction and for determination of the sign by two phase shifted interferograms are presented. For demodulation of the wrapped phase, a path independent algorithm is described.
<title>Critical alignments in plane mirror interferometry</title> (1992)

A model of two dimensional in-plane metrology using plane mirror interferometry is developed based on an archetype measuring configuration. The purpose of the model is to define and study the key factors limiting the accuracy of this system. Geometric errors are studied under the assumption that component motions and transducers are linear, but not necessarily in alignment. Abbe offsets depend on higher order terms and are neglected in the first order analysis. This study provides some interesting clarifications of which alignment errors are most important and what is meant by cosine error and alignment error.
Necessary extensions of fieldbus systems for distributed processing (2002)

Supervisory and control systems are characterized by proprietary hardware, software and communication systems. As a result of the introduction of standardized fieldbus systems into practical use, it becomes possible and necessary to provide the interoperability of application functions and to get open distributed supervisory and control systems (DSCSs). Furthermore it is necessary to add to the control loop between the technological process and the supervisory and control functions a second control loop between the supervisory and control functions and the management of the DSCS. This paper shows which application functions are necessary for distributed processing, classifies and models control functions and management functions and derives an information model for the device. Furthermore, it is shown which parts of the developed model are already specified in PROFIBUS-PA and which other standardisation activities are under way.
Glutaredoxin function for the carboxyl-terminal domain of the plant-type 5′-adenylylsulfate reductase (1998)

5'-Adenylylsulfate (APS) reductase (EC 1.8.99.-) catalyzes the reduction of activated sulfate to sulfite in plants. The evidence presented here shows that a domain of the enzyme is a glutathione (GSH)-dependent reductase that functions similarly to the redox cofactor glutaredoxin. The APR1 cDNA encoding APS reductase from Arabidopsis thaliana is able to complement the cysteine auxotrophy of an Escherichia coli cysH [3'-phosphoadenosine-5'-phosphosulfate (PAPS) reductase] mutant, only if the E. coli strain produces glutathione. The purified recombinant enzyme (APR1p) can use GSH efficiently as a hydrogen donor in vitro, showing aKm[GSH] approximately of 0.6 mM. Gene dissection was used to express separately the regions of APR1p from amino acids 73-327 (the R domain), homologous with microbial PAPS reductase, and from amino acids 328-465 (the C domain), homologous with thioredoxin. The R and C domains alone are inactive in APS reduction, but the activity is partially restored by mixing the two domains. The C domain shows a number of activities that are typical of E. coli glutaredoxin rather than thioredoxin. Both the C domain and APR1p are highly active in GSH-dependent reduction of hydroxyethyldisulfide, cystine, and dehydroascorbate, showing a Km[GSH] in these assays of approximately 1 mM. The R domain does not show these activities. The C domain is active in GSH-dependent reduction of insulin disulfides and ribonucleotide reductase, whereas APR1p and R domain are inactive. The C domain can substitute for glutaredoxin in vivo as demonstrated by complementation of an E. coli mutant, underscoring the functional similarity between the two enzymes.
Upconversion Lasers: Stable and Low‐Threshold Optical Gain in CdSe/CdS Quantum Dots: An All‐Colloidal Frequency Up‐Converted Laser (Adv. Mater. 17/2015) (2015)

An all-colloidal vertical-cavity surface-emitting laser (VCSEL) is reported by C. Dang, H. Sun, H. V. Demir and co-workers on page 2741, which offers high performance and stability while being fully solution processed. This all-colloidal laser is based on a stacked architecture of dielectric mirrors, based on metal oxide nanoparticles sandwiching semiconductor nanocrystals as the optical gain medium, forming an all-solution-processed VCSEL structure. Here, using tailored core-shell quantum dots that have suppressed non-radiative Auger recombination enables the achievement of sub-mJ cm−2 frequency up-converted lasing thresholds, which make these all-colloidal devices highly promising for optoelectronic and biomedical applications.
Comparing the Effects of Inhaled Pulmonary Vasodilators and Their Diluents on Airway Inflammation and Ciliary Function (2018)

Background:Nitric oxide (NO) and epoprostenol (EPO) are inhaled therapies for pulmonary hypertension. The most common diluents for EPO, glycine (GLY) and arginine (ARG), have a pH of 11-13. pH > 10 has been shown to cause cessation of ciliary beating, cell sloughing, and inhibition of airway drug transport. The effects of EPO-GLY and EPO-ARG on airway epithelia are unknown. NO has been reported to be conditionally pro- or anti-inflammatory. NO donor compounds have disparate effects upon inflammatory mediators in airway cells, but this has not been evaluated in response to NO gas. We hypothesized that EPO-GLY and EPO-ARG would increase inflammatory markers in airway epithelia and that NO exposure would not increase the production of inflammatory markers. Methods:Pseudostratified ciliated columnar epithelium (Figure 1) were exposed to NO (20 ppm), EPO-GLY (30 ng/mL), EPO-ARG (30 ng/mL), GLY, ARG, or phosphate-buffered saline (PBS, control). pH of each solution was measured immediately prior to exposure; PBS pH was 7.0, EPO-GLY and GLY pH was 12, EPO-ARG and ARG pH was 12.9. We harvested cell media and lysate for measurement of inflammatory markers. Ciliary beat was observed at each time interval using light microscopy. High-definition video images were recorded. Post-processing included noise reduction and point-feature matching to enhance visualization of cell movement. Ciliary cell clusters were directly observed and ciliary beat frequency (CBF) calculated for each experiment. Results:In all cells exposed to GLY, EPO-GLY, ARG, and EPO-ARG ciliary beat decreased immediately (p < 0.05, Figure 1) and ceased within five min of exposure. In control groups and NO group, ciliary beat remained throughout exposure. All cells exposed to GLY, EPO-GLY, ARG, and EPO-ARG died within 30 min of exposure. Lactate dehydrogenase (LDH), an established indicator of cell-stress/cell death, was evaluated via colorimetric assay in all of these groups. LDH was significantly elevated in GLY and EPO-GLY (Figure 1). LDH was not detectable in the ARG or EPO-ARG groups in the (Figure 1) ; to verify cell death, total RNA was evaluated in the mixture of culture media and cellular debris remaining after exposure. No RNA was detectable, indicating total cell death (Figure 1). LDH was no different between the cells exposed to NO and the control group (Figure 1). Conclusions:Apical exposure of EPO-GLY, EPO-ARG, GLY, or ARG causes ciliary beat cessation and cell death in NHBE cells.
A heightfield on an isometric grid (2004)

We describe a data structure for improved quality of real-time rendering for large and dynamic heightfields on programmable graphics hardware. The new isometric heightfield has a more accurate surface and smoother shading, normals, and curvature.
VEGFR1 single nucleotide polymorphisms associated with outcome in patients with metastatic renal cell carcinoma treated with sunitinib – a multicentric retrospective analysis (2013)

Ninety-one patients were included. We found that mRCC patients with the CC-variant in rs9582036 in VEGFR1 have a poorer response rate (RR) (0% vs. 46%, p = 0.028), a poorer PFS (10 vs. 18 months, p = 0.033 on univariate and 0.06 on multivariate analysis) and a poorer OS (14 vs. 31 months, p = 0.019 on univariate and 0.008 on multivariate analysis) compared to patients with the AC- and AA-genotypes. mRCC patients with the AA-variant in rs9554320 in VEGFR1 have a poorer PFS (12 vs. 21 months, p = 0.0066 on univariate and 0.005 on multivariate analysis) and a poorer OS (22 vs. 34 months, p = 0.019 on univariate and 0.067 on multivariate analysis) compared to patients with the AC- and CC-genotypes. Interpretation. mRCC patients with the CC-genotype in VEGFR1 SNP rs9582036 have a poorer response rate, PFS and OS when treated with sunitinib. These findings are in agreement with the association of rs9582036 and outcome observed in bevacizumab treated pancreatic cancer patients. Prospective validation of this SNP is warranted.
