Degraded partial palmprint recognition for forensic investigations (2009)

Palmprint trait is emerging as a new and practical biometric solution and a few systems using full palmprints have been proposed. However, partial palmprints left at scenes of crime have not yet been exploited to recognize and find crime suspects. In this paper, a modified well known algorithm, referred to as modified phase only correlation (MPOC) is proposed to match poor quality (degraded) partial palmprints left by suspects at crime scenes against a full palmprint registered in a template database. Instead of using the conventional peak as the matching score between two palmprint images, the ratio of the conventional peak to the highest peak in the outside-lobe correlation plane is employed. Experiments were conducted on a generated database of 800 partial palmprints having an area less than 25% of that of the full palmprint images from which blurred and degraded images were created by adding an intense synthetic Gaussian noise. The results show that the proposed method yields high recognition performance thus demonstrating its ability to tackle the problem of identifying low quality partial palmprint images giving an equal error rate (EER) less than 0.4%.
MDPOP (2006)

We model social choice problems in which self interested agents with private utility functions have to agree on values for a set of variables subject to side constraints. The goal is to implement the efficient solution, maximizing the total utility across all agents. Existing techniques for this problem fall into two groups. Distributed constraint optimization algorithms can find the solution without any central authority but are vulnerable to manipulation. Incentive compatible mechanisms can ensure that agents report truthful information about their utilities and prevent manipulation of the outcome but require centralized computation.Following the agenda of distributed implementation [16], we integrate these methods and introduce MDPOP, the first distributed optimization protocol that faithfully implements the VCG mechanism for this problem of efficient social choice. No agent can benefit by unilaterally deviating from any aspect of the protocol, neither information-revelation, computation, nor communication. The only central authority required is a bank that can extract payments from agents. In addition, we exploit structure in the problem and develop a faithful method to redistribute some of the VCG payments back to agents. Agents need only communicate with other agents that have an interest in the same variable, and provided that the distributed optimization itself scales the entire method scales to problems of unbounded size.
Revascularization Trends in Patients With Diabetes Mellitus and Multivessel Coronary Artery Disease Presenting With Non–ST Elevation Myocardial Infarction (2016)

Among patients with diabetes mellitus and multivessel coronary artery disease presenting with non-ST-segment-elevation myocardial infarction, only one third undergo CABG during the index admission. Furthermore, the use of PCI, but not CABG, increased modestly over the past 6 years.
Lipopolysaccharide as an Antigen Target for the Formulation of a Universal Vaccine against<i>Escherichia coli</i>O111 Strains (2010)

A promising approach to developing a vaccine against O111 strains of diarrheagenic Escherichia coli that exhibit different mechanisms of virulence is to target either the core or the polysaccharide chain (O antigen) of their lipopolysaccharide (LPS). However, due to structural variations found in both these LPS components, to use them as antigen targets for vaccination, it is necessary to formulate a vaccine able to induce a humoral immune response that can recognize all different variants found in E. coli O111 strains. In this study, it was demonstrated that, despite differences in composition of oligosaccharide repeat units between O111ab and O111ac LPS subtypes, antibodies against one O111 subtype can recognize and inhibit the adhesion to human epithelial cells of all categories of O111 E. coli (enteropathogenic E. coli [EPEC], enterohemorrhagic E. coli [EHEC], and enteroaggregative E. coli [EAEC]) strains regardless of the nature of their flagellar antigens, mechanisms of virulence, or O111 polysaccharide subtypes. These antibodies were also able to increase the clearance of different strains of O111 E. coli by macrophages. PCR analyses of the pathways involved in O111 LPS core biosynthesis showed that all EAEC strains have core type R2, whereas typical EPEC and EHEC have core type R3. In contrast, atypical EPEC strains have core types R2 and R3. In summary, the results presented herein indicate that the O111 polysaccharide and LPS core types R2 and R3 are antigen targets for panspecific immunotherapy against all categories of O111 E. coli.
Application of the Statistical Associating Fluid Theory (SAFT) for the calculation of the vapour-liquid equilibrium: Modeling of the N2O4-NO2 reacting system (2007)

Accurate thermophysical properties are mandatory for all industrial applications. However, experimental data are often scarce and models are needed for the estimation of the properties. Such is the case in supercritical processes like the selective oxidation of vegetal macromolecules in mixture NO2/N2O4 – supercritical CO2 [1]. Currently, the process optimization is incomplete due to the unability to assess experimental the fraction of free NO2 monomer in the reactor. Statistical Associating Fluid Theory (SAFT) is a powerful equation of state model for thermodynamic property and phase equilibria calculations for fluid mixtures. It has been used to describe with an equation of state approach non polar and polar compounds, with particular attention to associating compounds.\nIn this work we use a modified version of the SAFT EOS, the so called soft-SAFT equation of state extended by a crossover treatment to take into account the long density fluctuation encountered when the critical region is approached [2]. The equation is applied to predict vapour liquid equilibria for NO2 that can self associate into N2O4 [3]. Both molecules NO2 and N2O4 are rigid molecules and the self association equilibrium is quickly achieved [4]. The procedure of modeling of such system consists in considering the monomer NO2 as an associating fluid with a strong association strength that represents the covalent bond between the N-N atoms. The system is successfully modeled by crossover soft-SAFT EOS by a set of parameters of only NO2 with a self association to form the dimmer (N2O4). The equation is also applied to a mixture NO2-N2O4/CO2 where good agreement is obtained with experimental data of the CO2 mass fraction.
Improvement in anH-plane nonreciprocal ferrite phase shifter via loading dielectric slabs (2001)

A technique is introduced to improve the performance of H-plane nonreciprocal ferrite phase shifters. This technique effectively combines dielectric loading on the H- and E-planes of the device. To determine the effect of dielectric loading qualitatively, a numerical analysis is carried out using the finite-element method (FEM). The method uses the magnetic vector and electric scalar potentials, which is proven to be very beneficial for eliminating a large number of spurious modes. Experimental verification of the theoretical predictions is established, and it indicates that dielectric loading in the H-plane can increase the differential phase shift of the device significantly. Furthermore, dielectric loading in the E-plane of the device is not only helpful to improve the heat-conducting characteristic of the device, but also is beneficial to increase the differential phase shift of the device, which makes it possible to fabricate devices with wideband and higher average power. © 2001 John Wiley & Sons, Inc.

Effect of a mutation preventing lipid modification on localization of the pCloDF13-encoded bacteriocin release protein and on release of cloacin DF13 (1988)

The pCloDF13-encoded bacteriocin release protein (BRP; Mr 2,871) is essential for the translocation of cloacin DF13 across the cell envelope of producing Escherichia coli cells. Overproduction of this BRP provokes lysis (quasilysis) of cells. Construction and analysis of a hybrid BRP-beta-lactamase protein (BRP-Bla) demonstrated that the BRP contains a lipid modified cysteine residue at its amino terminus and is mainly located in the outer membrane. The significance of lipid modification for the localization and functioning of the BRP was investigated. Site-directed mutagenesis was used to substitute the cysteine residue for a glycine residue in the lipobox of the BRP and the BRP-Bla protein. The mutated BRP was unable to bring about the release of cloacin DF13 and could not provide the lysis (quasilysis) of host cells. However, the mutated BRP strongly inhibited the colony-forming ability of the cells, indicating that induction of the mutated protein still affected cell viability. In contrast to the wild-type BRP-Bla protein, the mutated BRP-Bla protein was mainly located in the cytoplasmic membrane, indicating that the mutation prevented the proper localization of the protein. The results indicated that lipid modification of the BRP is required for its localization and release of cloacin DF13, but not for its lethality to host cells.
A novel orange-yellow-emitting Ba<sub>3</sub>Lu(PO<sub>4</sub>)<sub>3</sub>:Eu<sup>2+</sup>,Mn<sup>2+</sup>phosphor with energy transfer for UV-excited white LEDs (2012)

Eu(2+)-Mn(2+) codoped orange-yellow-emitting Ba(3)Lu(PO(4))(3) phosphors were synthesized by a solid-state reaction. The synthesis, structure refinement, and luminescence properties of the obtained phosphor were first investigated in detail. The crystal structure was refined with a split-atom model, where the oxygen atoms are distributed over two partially occupied sites. The refinement confirmed that BLuP:0.005Eu(2+),0.06Mn(2+) has a cubic unit cell with space group I43d (no. 220), cell parameters a = b = c = 10.4025 Å and Z = 4. The luminescent properties reveal that the developed phosphor can efficiently convert UV photons in a broad range from 230 to 430 nm into orange-yellow emission. On the basis of the luminescence spectra and fluorescence decay curves, we confirm that the energy transfer process from the Eu(2+) to Mn(2+) ions takes place in the codoped Ba(3)Lu(PO(4))(3):Eu(2+),Mn(2+) phosphor, and the energy transfer efficiency increases with an increase in the Mn(2+) content. The possible energy transfer mechanism was proposed in terms of the experimental results and analysis. In particular, our developed phosphor contains a larger amount of the red-emitting component, compared with the commercial YAG:Ce phosphor, possessing favorable properties for application in warm white LEDs with low correlated color temperature.
Physiological bases of tolerance of abiotic stresses in rice and mechanisms of adaptation (2013)

Rice is grown over a wide range of climatic and edaphic conditions. The large gap in the productivity of rainfed ecosystems compared with irrigated ecosystem is largely caused by abiotic stresses such as drought, floods, and poor soils, coupled with the lack of well-adapted high-yielding varieties. Substantial progress has been made in unravelling the physiological and molecular bases of tolerance, however, progress in developing high yielding, tolerant varieties has been slow because of the undesirable phenotypes of the tolerant donors and the complexity of the tolerance mechanisms. Flash-floods normally affect rice during vegetative stage, however, in areas where direct seeding is practiced, heavy rains immediately after seeding cause severe damage to germinating seeds, resulting in poor crop stand. Complete submergence annually affects about 16 million ha of rice in South and Southeast Asia, and about one third of the total rice growing area in Africa. Salinity is particularly troubling in coastal regions in the tropics because of marine influence and build up of salt in some inlands as a consequence of excessive irrigation with improper drainage. Mechanism of adaptation of rice to flooded condition at different stages of crop growth and adaptation to salt stress have been reviewed in the present paper.
Do contemporary imaging and biopsy techniques reliably identify unilateral prostate cancer? Implications for hemiablation patient selection (2019)

Clinicians and patients must weigh the risk of inadequate oncologic treatment against the functional benefits of hemiablation. Further investigation into methods for improving patient selection for hemiablation is necessary.
Artwork imaging from 370 to 1630 nm using a novel multispectral system based on light‐emitting diodes (2014)

Abstract The recent use of multispectral systems as a noncontact method for analysis of artworks has already shown promising results. This study explains the application of a novel portable multispectral system based on light‐emitting diodes (LEDs) for artwork imaging. This method provides spectral information in a spectral range from 370 to 1630 nm with a 25 cm × 25 cm field of view by using two different image sensors in synchrony with 23 bands of irradiation. The spectral information for each point is estimated and validated using the pseudo‐inverse and spline interpolation methods for spectral estimation and three different evaluation metrics. The results of the metrics obtained with both estimation methods show a general good performance of the system over the whole spectral range. The experiments also showed that the selection of the training set for the pseudo‐inverse estimation has a great influence in its performance, and thus, it defines whether or not the pseudo‐inverse outperforms the spline interpolation method. The system is applied in situ to the study of Catalan art masterpieces, and the results demonstrate the potential of a cost‐effective and versatile system using various off‐the‐shelf elements to reconstruct color information and to reveal features not previously identified. © 2014 Wiley Periodicals, Inc.

Independent Regulation by Sodium Butyrate of Gonadotropin Alpha Gene Expression and Cell Cycle Progression in HeLa Cells (1984)

Sodium butyrate alters the growth and gene expression of a variety of differentiating and neoplastic cell types. For example, addition of 5 mM butyrate to HeLa cells is reported to both induce gonadotropin alpha subunit biosynthesis and block cell cycling in G1. We have studied these two actions of butyrate on HeLa cells and found that they are regulated in distinct ways. The induction of alpha subunit synthesis was due to an increase in the rate of transcription of the alpha gene. Using synchronized populations of HeLa cells, we determined that butyrate stimulates alpha transcription throughout the cell cycle. In contrast, treated cells arrest in G1 only if exposed to butyrate for a discrete period during the previous S phase. We conclude that butyrate inhibits DNA synthesis through a cell cycle-specific action that is independent from its direct action to stimulate transcription of the gonadotropin alpha gene.
A European Field Assessment of the efficacy of fluralaner (Bravecto®) chewable and spot-on formulations for treatment of dogs with generalized demodicosis (2020)

Abstract Background : Recent reports indicate that the isoxazoline compounds have the potential to provide safe and effective treatment of canine generalized demodicosis, a condition that has been traditionally difficult to cure. Controlled field studies are needed to confirm this potential. A study was therefore initiated to investigate the efficacy of a single oral or spot-on treatment with fluralaner, an isoxazoline, compared with multiple topical treatments with imidacloprid-moxidectin, in dogs naturally affected by generalized demodicosis. Methods : Veterinary clinics in 5 European countries enrolled 134 dogs diagnosed with generalized demodicosis. Dogs were randomized to treatment with either fluralaner chewables, fluralaner spot-on, or topical imidacloprid-moxidectin in a 2:2:1 ratio. Both fluralaner formulations were administered once, at the approved dose rate, on day 0. Imidacloprid-moxidectin was administered per label on day 0, and every 4 weeks, more frequently if necessary. At each visit (days 0, 28, 56, 84), dogs were monitored for demodectic mites, using deep skin scrapings, and observed for health and for severity of skin lesions. Treatment was considered efficacious if more than 90% of the dogs were free of live mites at both days 56 and 84. Results : Of 124 dogs completing the study, 57 were diagnosed with juvenile-onset demodicosis and 67 with the adult-onset form. A single treatment with oral or spot-on fluralaner was efficacious, each eliminating mites from at least 98.0% of treated dogs on days 56 and 84. Against juvenile-onset demodicosis, efficacy of the oral and spot-on formulations was 96.0% and 100%, respectively, and against adult-onset demodicosis 100% and 96.7%. Multiple administrations of imidacloprid-moxidectin were not efficacious, eliminating mites from 87.5% of dogs (92.0% with juvenile-onset demodicosis cured; 81.8% with adult-onset demodicosis). All groups showed a marked reduction in skin lesions by day 28, with continuing clinical improvement at each subsequent visit through day 84. There were no treatment-related adverse events. Conclusion : A single administration of fluralaner chewables or fluralaner spot-on is highly effective against juvenile-onset and adult-onset forms of generalized canine demodicosis. Topically applied imidacloprid-moxidectin at weekly to monthly intervals over the 84-day study did not achieve the proportion of mite-free dogs required to demonstrate efficacy.
Omnivorous Looper Control On Avocados, Jul 1980 (1982)

Abstract Insecticides were tested for control of late instar omnivorous looper (OL) larvae on 3-yr-old trees (18 ft x 18 ft spacing) located in San Diego County, Ca. A randomized block experimental design was used with 5 single-tree replicates. Treatments were applied by hand-gun with an FMC hydraulic sprayer on Jul 9 at 400 psi to run-off (ca 3 gal/tree - 300 gal/acre). Treated trees were separated by at least 1 untreated buffer tree on all sides. Treatments were evaluated by examining 40 randomly selected 0L nests/tree for live larvae. Data were subj’ected to analysis of variance after transformation to x.
Ross River Virus Disease Clusters and Spatial Relationship with Mosquito Biting Exposure in Redland Shire, Southern Queensland, Australia (2006)

The spatial heterogeneity in the risk of Ross River virus (family Togaviridae, genus Alphavirus, RRV) disease, the most common mosquito-borne disease in Australia, was examined in Redland Shire in southern Queensland, Australia. Disease cases, complaints from residents of intense mosquito biting exposure, and human population data were mapped using a geographic information system. Surface maps of RRV disease age-sex standardized morbidity ratios and mosquito biting complaint morbidity ratios were created. To determine whether there was significant spatial variation in disease and complaint patterns, a spatial scan analysis method was used to test whether the number of cases and complaints was distributed according to underlying population at risk. Several noncontiguous areas in proximity to productive saline water habitats of Aedes vigilax (Skuse), a recognized vector of RRV, had higher than expected numbers of RRV disease cases and complaints. Disease rates in human populations in areas which had high numbers of adult Ae. vigilax in carbon dioxide- and octenol-baited light traps were up to 2.9 times those in areas that rarely had high numbers of mosquitoes. It was estimated that targeted control of adult Ae. vigilax in these high-risk areas could potentially reduce the RRV disease incidence by an average of 13.6%. Spatial correlation was found between RRV disease risk and complaints from residents of mosquito biting. Based on historical patterns of RRV transmission throughout Redland Shire and estimated future human population growth in areas with higher than average RRV disease incidence, it was estimated that RRV incidence rates will increase by 8% between 2001 and 2021. The use of arbitrary administrative areas that ranged in size from 4.6 to 318.3 km2, has the potential to mask any small scale heterogeneity in disease patterns. With the availability of georeferenced data sets and high-resolution imagery, it is becoming more feasible to undertake spatial analyses at relatively small scales.
Toward the Environmentally-Friendly Small Engine: Fuel, Lubricant, and Emission Measurement Issues (1991)

Metal-organic frameworks (MOFs) based on zirconium phosphonates exhibit superior chemical stability suitable for applications under harsh conditions. These compounds mostly exist as poorly crystallized precipitates, and precise structural information has therefore remained elusive. Furthermore, a zero-dimensional zirconium phosphonate cluster acting as secondary building unit has been lacking, leading to poor designability in this system. Herein, we overcome these challenges and obtain single crystals of three zirconium phosphonates that are suitable for structural analysis. These compounds are built by previously unknown isolated zirconium phosphonate clusters and exhibit combined high porosity and ultrastability even in fuming acids. SZ-2 possesses the largest void volume recorded in zirconium phosphonates and SZ-3 represents the most porous crystalline zirconium phosphonate and the only porous MOF material reported to survive in aqua regia. SZ-2 and SZ-3 can effectively remove uranyl ions from aqueous solutions over a wide pH range, and we have elucidated the removal mechanism.

Novel Nanostructures and Optical Properties of Silver Doped Sodium Phosphate Thin Films (2009)

(50-x)Na2O-50P2O5-xAgCl (x = 0 to 15 mol%) glasses in bulk form were synthesized using melt-quenching technique. Thin films of these silver doped sodium phosphate glasses were deposited by thermal evaporation process. The influence of deposition of these glasses in thin film form and subsequent annealing at 600 degrees C on the structure and optical properties such as transmittance, reflectance, refractive index and band gap have been investigated in detail. X-ray diffraction studies of the as-deposited films show the films to be amorphous whereas annealed films show existence of orthorhombic and monoclinic phase of NaPO3 along with crystalline cubic phase of AgCl in doped glasses. Structural investigations of these annealed films show unique morphologies (needle-like and granular) at nano-scale. Both as-fabricated and annealed films are poor reflectors but show high transmittance in the entire spectral region under consideration, which is a direct consequence of particle size effects. Indirect band gap narrowing and variation in refractive index upon annealing is consistent with nanostructural transformations in these samples.
