Social User Interest Mining (2019)

he abundance of user generated content on social networks pro-vides the opportunity to build models that are able to accurately and effectively extract, mine and predict users' interests with the hopes of enabling more effective user engagement, better quality delivery of appropriate services and higher user satisfaction. While traditional methods for building user profiles relied on AI-based preference elicitation techniques that could have been considered to be intrusive and undesirable by the users, more recent advances are focused on a non-intrusive yet accurate way of determining users' interests and preferences. In this tutorial, we cover five important aspects related to the effective mining of user interests: (1) we introduce the information sources that are used for extracting user interests, (2) various types of user interest profiles that have been proposed in the literature, (3) techniques that have been adopted or proposed for mining user interests, (4) the scalability and re-source requirements of the state of the art methods, and finally (5)the evaluation methodologies that are adopted in the literature for validating the appropriateness of the mined user interest profiles.We also introduce existing challenges, open research question and exciting opportunities for further work.
Efficient numerical simulation of high-NA i-line lithography processes (1992)

Numerical algorithms employing the ID imaging model and the 2D wave-guide scattering model were implemented to achieve high speed in simulating high NA i-line processes. The CPU consumption and the range of validity of the models used were discussed. The simulator was applied to study the possibility of imaging 0.35/mi lines and spaces(L/S) utilizing lenses of NA=0.55, 0.60 and 0.65 and single layer resist (SLR) processes.
Path Diversity for Overlay Multicast Streaming (2004)

In this paper, we propose a new path-diversity based scheme for application layer multicast streaming over the Internet. Rather than building simple trees as in traditional multicast, we construct multicast k-DAGs, characterized by the property that each receiver has k parents. This multiplicity of parents, not only allows for streaming from multiple sources at the same time, thereby decorrelating losses, but also creates an opportunity to dynamically adapt streaming rates from these senders depending on the existing error conditions in the network. To exploit these possibilities, we use a simple rateallocation algorithm and a packet-partitioning algorithm that allows a receiver to co-ordinate the sending of data from amongst its parents. Our results show that our scheme is effective in dealing with packet losses in the network, and increases the goodput of FEC-coded video data by 15-30%.
Understanding the limitations of removal of hemicelluloses during authohydrolysis of a mixture of Southern hardwoods (2010)

Extraction of hemicelluloses from wood prior to pulping is being pursued to generate more value-added products, while still producing high quality pulp from the pre-extracted wood. For a better understanding of the factors limiting selective extraction, enzymatic hydrolysis in combination with size exclusion chromatography (SEC) was applied to milled wood and hydrothermally treated wood. Complete dissolution was achieved in a lithium chloride/dimethylacetamide solvent system after mild ball-milling of a Southern Hardwood Mixture (SHM), of SHM extracted using auto-hydrolysis, and of enzyme-treated SHM. SEC tests showed that severe degradation of wood polymers occurred after a milling time of 3 hours. The SEC data also confirmed the presence of lignin-carbohydrate complexes. Based on the results, it is suggested that linkages between lignin and polysaccharides may play an important role in limiting extraction of hemicelluloses.
Study of water holding capacity and water retention ability of bacterial cellulose produced with addition of glucoronic acid oligomers (2010)

Bacterial cellulose (BC) has unique properties such as biocompatibility, polyfunctionality, hydrophilicity and low production cost. The high water holding capacity (WHC) and water retention (WR) ability are among the best properties of BC which make it suitable to be used indifferent biomedical applications. BC has a broad prospective for application in different fields including artificial skins, blood vessels, face masks, wound dressing and control drug release etc. In the present study, BC was prepared by Gluconacetobacter hansenii PJK and Acetobacter xylinum in static culture by adding 1 % glucoronic acid oligomers (GO) as an additional substance to the chemically defined medium. WHC and WR values of the prepared BC sheets prepared at different experimental conditions were determined and compared. WHC and WRvalues of the BC sheets prepared with GO were higher compared to control and similarly, these were higher for A. xylinum compared to G. hansenii PJK.

Investigations of the influence of a tapered fiber on spectrum of femtosecond pulses train (2003)

We propose an experimental results and theoretical description of the ultrashort pulse train spectral broadening in tapered fibers. Multi-peak spectral structure due to the effect of self-phase modulation was obtained. Phase and amplitude fluctuations were investigated. Shown that stability of intermode beats decreased slightly after the propagation through tapered fiber. A technique and results of high precision measurements of the intermode frequency of a femtosecond Ti:sapphire laser for investigation of the influence of a tapered fiber are described. The experiments have shown that the intermode frequency stability does not depend on the broadened spectrum range.
Spike Count Reliability and the Poisson Hypothesis (2006)

The variability of cortical activity in response to repeated presentations of a stimulus has been an area of controversy in the ongoing debate regarding the evidence for fine temporal structure in nervous system activity. We present a new statistical technique for assessing the significance of observed variability in the neural spike counts with respect to a minimal Poisson hypothesis, which avoids the conventional but troubling assumption that the spiking process is identically distributed across trials. We apply the method to recordings of inferotemporal cortical neurons of primates presented with complex visual stimuli. On this data, the minimal Poisson hypothesis is rejected: the neuronal responses are too reliable to be fit by a typical firing-rate model, even allowing for sudden, time-varying, and trial-dependent rate changes after stimulus onset. The statistical evidence favors a tightly regulated stimulus response in these neurons, close to stimulus onset, although not further away.
Uranium Removal from Ground Water Using Zero Valent Iron Media (1999)

Abstract Removal of uranium from contaminated ground water using zero valent iron is currently under evaluation at several U.S. Department of Energy (DOE) facilities. Uranium removal by zero valent iron may occur via adsorption onto iron corrosion products, and by reduction to less soluble valence states by reactions with elemental iron. This research investigated the effects of water chemistry and surface precipitate buildup on the removal of soluble uranium by zero valent iron. Batch testing was performed to assess solution chemistry effects on uranium adsorption to the potential iron corrosion products, magnetite and a mixed valent amorphous iron oxide. Uranium adsorption to the simulated iron corrosion products was highly dependent on pH, and the concentration and speciation of the background electrolyte solution. Uranium removal via reduction by elemental iron closely approximated pseudo‐first‐order removal kinetics, despite the buildup of up to 40,000 monolayers of precipitated uranium on the iron surfaces. This indicates that the rate of uranium removal is not strongly dependent on the thickness of the adsorbed uranium layer. Short‐term rates of uranium reduction were similar for all solutions tested, but long‐term rates were highly dependent on water chemistry. Compared to deionized water, uranium removal rates were increased in sodium chloride containing solutions and reduced in sodium nitrate solutions. The strong influence of water chemistry on long‐term reduction rates indicates that system design will require extnded testing with the ground water of interest.
Trajectory Optimization for Autonomous Vehicles on Crossroads with Mobile Obstacles (2018)

Autonomous vehicles issues have emerged in the past years. Among the classic trajectory planning methods, the potential field method, which is mainly local, is purely reactive to the environment and creates rough trajectories. In this article the creation of a dynamic optimal minimum of the potential is proposed, using multi-criteria trajectory optimization, for unmanned terrestrial vehicles. Obstacles are mobile and with the anticipation of their movement, motion and path of this optimal dynamic minimum are jointly generated. The effects of adding this anticipation in the planning are illustrated, and the optimization is done using a Genetic Algorithm (GA), to improve the Potential Fields (PF) method. In the first two parts of this article, the problem is formulated and the different criteria are described. Then, a GA-PF method is proposed. Finally simulations of the potential field method and its combination with a genetic algorithm are presented.
The Significance of Pulmonary Interstitial Emphysema in Live Birth Determination (2004)

The utility of pulmonary interstitial emphysema (PIE) in live birth determination is not well established. Because the distinction between live birth and stillbirth may be important in criminal proceedings, we undertook this study to investigate the relationship between the histologic finding of PIE and live birth. Sixty-six cases of infant death were retrieved and compared with 21 stillborn infants. Histologic sections of the lungs were characterized as "florid PIE," "equivocal PIE," or "absent PIE." Sixteen cases of florid PIE were identified, all in live born infants. Forty-seven cases of equivocal PIE were found in 36 live born and 11 stillborn infants. In 24 cases (14 live born infants and 10 stillborns), no PIE was identified. We examined the relationship between florid PIE in infants with sudden infant death syndrome (SIDS) or "sudden unexpected death in infancy, manner undetermined" (SUDI), and also its relationship to other variables. No association was found. The presence of equivocal PIE may be an artifact of tissue processing. Florid PIE is found only in live born infants. No correlation between the presence of florid PIE and cause of death could be determined.

Synthesis, Crystal Structures, Magnetic Properties and Catecholase Activity of Double Phenoxido-Bridged Penta-Coordinated Dinuclear Nickel(II) Complexes Derived from Reduced Schiff-Base Ligands: Mechanistic Inference of Catecholase Activity (2012)

Three double phenoxido-bridged dinuclear nickel(II) complexes, namely [Ni(2)(L(1))(2)(NCS)(2)] (1), [Ni(2)(L(2))(2)(NCS)(2)] (2), and [Ni(2)(L(3))(2)(NCS)(2)] (3) have been synthesized using the reduced tridentate Schiff-base ligands 2-[1-(3-methylamino-propylamino)-ethyl]-phenol (HL(1)), 2-[1-(2-dimethylamino-ethylamino)-ethyl]-phenol (HL(2)), and 2-[1-(3-dimethylamino-propylamino)-ethyl]-phenol (HL(3)), respectively. The coordination compounds have been characterized by X-ray structural analyses, magnetic-susceptibility measurements, and various spectroscopic methods. In all complexes, the nickel(II) ions are penta-coordinated in a square-pyramidal environment, which is severely distorted in the case of 1 (Addison parameter τ = 0.47) and 3 (τ = 0.29), while it is almost perfect for 2 (τ = 0.03). This arrangement leads to relatively strong antiferromagnetic interactions between the Ni(II) (S = 1) metal centers as mediated by double phenoxido bridges (with J values of -23.32 (1), -35.45 (2), and -34.02 (3) cm(3) K mol(-1), in the convention H = -2JS(1)S(2)). The catalytic activity of these Ni compounds has been investigated for the aerial oxidation of 3,5-di-tert-butylcatechol. Kinetic data analysis following Michaelis-Menten treatment reveals that the catecholase activity of the complexes is influenced by the flexibility of the ligand and also by the geometry around the metal ion. Electrospray ionization mass spectroscopy (ESI-MS) studies (in the positive mode) have been performed for all the coordination compounds in the presence of 3,5-DTBC to characterize potential complex-substrate intermediates. The mass-spectrometry data, corroborated by electron paramagnetic resonance (EPR) measurements, suggest that the metal centers are involved in the catecholase activity exhibited by the complexes.
An <i>L</i>2 calculation of the 1<i>s</i> and 2<i>s</i> photoionization cross sections of Ne (1979)

Discrete Gaussian orbitals are used to approximate the continuum for neon photoionization. Results within 2% of the exact numerical static exchange answer are obtained for both the 1s and 2s subshells by Stieltjes imaging. An alternative to the Tchebycheff method for obtaining the cross section from the moment distribution is given.
GE's Energy Rentals Business Automates Its Credit Assessment Process (2003)

GE Energy Rentals, a business unit of General Electric Power Systems (GEPS), uses an automated Web-based application to assess customers' credit worthiness. GE's Global Research Center developed the system using quantitative business modeling and decision-support-system design. The system uses a model for credit decisions that captures the thought process expert credit analysts use to assign credit lines to customers. In addition, the system provides users with the analytics and reasons underlying credit decisions. It has enhanced productivity and efficiency by speeding up credit approvals. In addition, by providing a standard platform for credit approvals, it ensures consistency in the process of assessing and approving credit. The system has decreased costs by eliminating a credit-analyst position despite growth in the business and has also saved over 60 percent of the costs per credit decision. We are adapting this approach for other GEPS business units.
Infrared thermal imagers for avionic applications (1999)

This paper deals with the design of two second generation thermal imagers that Alenia Difesa OFFICINE GALILEO has successfully developed for the Navigation FLIR of the NH90 Tactical Transportation Helicopter (NH90 TTH) and for the Electro-Optical Surveillance and Tracking System for the Italian 'Guardia di Finanza' ATR42 Maritime Patrol Aircraft (ATR42 MPA). Small size, lightweight and low power consumption have been the main design goals of the two programs. In particular the NH90 TTH Thermal Imager is a compact camera operating in the 8 divided by 12 micrometers bandwidth with a single wide field of view. The thermal imager developed for the ATR42 MPA features a three remotely switchable fields of view objective equipped with diffractive optics. Performance goals, innovative design aspects and test results of these two thermal imagers are reported.

Analytical Approach to Continuous and Intermittent Bottleneck Flows (2006)

We propose a many-particle-inspired theory for granular outflows from a hopper and for the escape dynamics through a bottleneck based on a continuity equation in polar coordinates. If the inflow is below the maximum outflow, we find an asymptotic stationary solution. If the inflow is above this value, we observe queue formation, which can be described by a shock wave equation. We also address the experimental observation of intermittent outflows, taking into account the lack of space in the merging zone by a minimum function and coordination problems by a stochastic variable. This results in avalanches of different sizes even if friction, force networks, inelastic collapse, or delay-induced stop-and-go waves are not assumed. Our intermittent flows result from a random alternation between particle propagation and gap propagation. Erratic flows in congested merging zones of vehicle traffic may be explained in a similar way.
Simple Water Measuring Device for On Farm Irrigation Evaluation (1990)

Laboratory experiments were conducted for the calibration of three flumes of different sizes. The logarithmic transformation in linear regression yielded excellent results for the stage-discharge relationship with coefficients of determination 0.998, 0.992, and 0.998 for 8 inches, 10 inches, and 12 inches circular flumes, respectively. The results showed that these flumes can be operated satisfactorily in flat irrigated areas, because limited head loss is required for the device to achieve critical flow conditions. The performance of flumes at non-level placement is satisfactory up to -3% slope, and up to +2% slope for higher flow only. The submergence tests showed good limits of tolerance to submergence. The average submergence limits were 90.9%, 87.7% and 86.9% for 8 inches, 10 inches, and 12 inches flume, respectively. This simple and low cost water measuring device has potential for use in managing and evaluating on-farm irrigation system.
Over-expression of thymosin beta4 promotes abnormal tooth development and stimulation of hair growth (2009)

Thymosin beta 4 has multi-functional roles in cell physiology. It accelerates wound healing, hair growth and angiogenesis, and increases laminin-5 expression in corneal epithelium. Furthermore, thymosin beta 4 stimulates tumor growth and metastasis by induction of cell migration and vascular endothelial growth factor-mediated angiogenesis. Using a construct on the skin-specific keratin-5 promoter, we have developed thymosin beta 4 over-expressing transgenic mice to further study its functional roles. Thymosin beta 4 in adult skin and in embryonic stages of the transgenic mouse was analyzed by both Western blot and immunohistochemistry. The over-expression of thymosin beta 4 was observed especially around hair follicles and in the teeth in the transgenic mice. We examined the phenotype of the thymosin beta 4 over-expressing mice. Hair growth was accelerated. In addition, the transgenic mice had abnormally-shaped white teeth and dull incisors. We found that the expression of laminin-5 was up-regulated in the skin of the transgenic mice. We conclude that thymosin beta 4 has an important physiological role in hair growth and in tooth development.
KNCM: Kernel Neutrosophic c-Means Clustering (2019)

Data clustering is an important step in data mining and machine learning. It is especially crucial to analyzethe data structures for further procedures. Recently a new clustering algorithm known as ‘neutrosophicc-means’ (NCM) was proposed in order to alleviate the limitations of the popular fuzzy c-means (FCM)clustering algorithm by introducing a new objective function which contains two types of rejection.

Photodynamic Activity of Dyes with Different DNA Binding Properties (1978)

The photosensitizing efficiencies of eight dyes have been compared; two acridines, two xanthene derivatives, one sulphur-containing dye and three chemotherapeutic agents. The analysed reaction was the photosensitized induction of free radicals in calf-thymus DNA at low temperature. The binding of these dyes to DNA was first measured. Both strong (process I) and weak (process II) binding, with different intensities, either alone or together, were observed as mode of fixation. Whatever the nature of their binding, all the dyes used revealed a photosensitizing power as inducers of peroxide radicals in DNA. Their relative efficiencies, expressed as a function of the amount of dye molecules bound to DNA, were found to be very different. Intercalation, however, appeared to favour the free-radical induction as the first strongly bound molecules were more efficient.
