Enhancement of Luminous Intensity of Spherical Y[sub 2]O[sub 3]:Eu Phosphors Using Flux during Aerosol Pyrolysis (2003)

Spherical phosphors of trivalent europium-activated yttrium oxide for flat panel displays were prepared from precursor solutions, which included various fluxes, by aerosol pyrolysis. The effects of the flux on the properties of prepared particles were investigated thoroughly by optical spectroscopy, X-ray spectroscopy, and scanning electron microscopy. To enhance the luminescence intensity of the spherical phosphors, the several fluxes, concentration of each flux, and synthetic temperature were examined and optimized by photoluminescence and cathodoluminescence measurements. The luminescent and physical characteristics of the prepared particles were sensitively influenced by the added flux. Particularly, the spherical phosphors produced from precursors incorporating sodium-based fluxes had relatively higher luminous efficiency. The red emission intensity of the spherical phosphor was increased by about 30% by the addition of compared with the intensity of alone. © 2003 The Electrochemical Society. All rights reserved.

Detection of computer generated faces in videos based on pulse signal (2015)

The rapid development in the field of computer graphics (CG) makes it quite easy to create photo-realistic images and videos. This brings forward an emergent requirement for techniques that can distinguish CG from real contents. In this paper, we propose a method that leverages human pulse signal to distinguish between CG and real videos that include human faces. We use a robust tracking method to locate a patch of skin on the face. Then, a chrominance-based algorithm is employed to robustly extract pulse signal. By checking the frequency waveform of the extracted pulse signal, we can tell CG and real videos apart. The experiment shows encouraging results, which demonstrate the efficiency of our method.
Design and development of the associated-particle three-dimensional imaging technique (1994)

The authors describe the development of the ``associated-particle`` imaging technique for producing low-resolution three-dimensional images of objects. Based on the t(d,n){sup 4}He reaction, the method requires access to only one side of the object being imaged and allows for the imaging of individual chemical elements in the material under observation. Studies were performed to (1) select the appropriate components of the system, including detectors, data-acquisition electronics, and neutron source, and (2) optimize experimental methods for collection and presentation of data. This report describes some of the development steps involved and provides a description of the complete final system that was developed.
Foiling the cracker: A survey of, and improvements to, password security (1992)

With the rapid burgeoning of national and international networks, the question of system security has become one of growing importance. High speed inter-machine communication and even higher speed computational processors have made the threats of system ‘‘crackers,’ ’ data theft, data corruption very real. This paper outlines some of the problems of current password security by demonstrating the ease by which indi-vidual accounts may be broken. Various techniques used by crackers are outlined, and finally one solution to this point of system vulnerability, a proactive password checker, is proposed. 1.
Browser Based Platform in Maintaining Clinical Activities – Use of The iPads in Head and Neck Clinics (2014)

Purpose: Incompatibility between documentation and clinical workflow causes physician resistance in organized data collection, which in turn complicates the use of data in patient care improvement. To resolve the gap, we developed an iPad compatible in situ browser-based platform that integrates clinical activity with data collection and analysis presentation. The ability to perform in-clinic activities and monitor decision making using the iPad was evaluated.
PGH<sub>2</sub>‐derived levuglandin adducts increase the neurotoxicity of amyloid β1–42 (2006)

The body of evidence indicating that oligomers of amyloid beta(1-42) (Abeta(1-42)) produce toxicity to neurons, together with our demonstration that prostaglandin H(2) (PGH(2)) oligomerizes amyloid beta(1-42), led to the examination of the neurotoxicity of amyloid beta(1-42) treated with PGH(2). The neurotoxic effects of Abeta(1-42) incubated with PGH(2) was examined in primary cultures of cerebral neurons of mice, monitoring the reduction of 3-(4,5-dimethylthiazole-2-yl)-2,5-diphenyltetrazolium bromide (MTT) as an indicator of cell toxicity. Whereas Abeta(1-42) itself, incubated for 24 h, has little or no effect on MTT reduction, Abeta(1-42) 24 h after exposure to PGH(2) produced a marked inhibition of MTT reduction, comparable with the inhibition resulting from Abeta(1-42) that has been oligomerized by incubation for 6 days. Similar results were obtained when Abeta(1-42) was incubated with levuglandin E(2) (LGE(2)), a reactive aldehyde formed by spontaneous rearrangement of PGH(2). The oligomers formed from reaction of Abeta(1-42) with LGE(2) exhibit immunochemical similarity with amyloid-derived diffusible ligands (ADDLs), as determined by analysis of the products of reaction of Abeta(1-42) with LGE(2) using western blotting with an antibody that is selective for ADDLs.
Mutations in subunit 6 of the F<sub>1</sub>F<sub>0</sub>‐ATP synthase cause two entirely different diseases (1997)

A lowered efficiency of oxidative phosphorylation was recently found in a Leber hereditary optic neuropathy (LHON) proband carrying a mutation in the mtDNA gene for subunit 6 of the membrane-bound F0 segment of the F1F0-ATP synthase [9]. This phenotype was transferred to cytoplasmic hybrid cells together with the mutation, proving its functional significance. Increasing the respiratory rate in the mitochondria from this mutant raised the ATP/2e- ratio back to normal values. A different mutation in the same mtDNA gene has been found in patients with the NARP syndrome [10]. Although the ATP/2e- ratio is also decreased in this mutant, in this case an increase in the respiratory rate could not compensate for it. Whilst both mutations affect subunit 6 of the proton-translocating F0 segment, the LHON mutation induces a proton leak whereas the NARP mutation blocks proton translocation. Hence, the latter will have much more destructive metabolic consequences in agreement with the large clinical differences between the two diseases.
Recombinant BCG coexpressing Ag85B, ESAT-6 and mouse-IFN-γ confers effective protection against<i>Mycobacterium tuberculosis</i>in C57BL/6 mice (2007)

In this study, the protective efficacy of a novel recombinant bacille Calmette Géurin (BCG) strain (rBCG-AEI) expressing fusion protein the antigen 85B (Ag85B)- the 6-kDa early secreted antigen target (ESAT-6)-IFN-gamma against Mycobacterium tuberculosis H37Rv in mice was evaluated. The immunogenicity study showed that rBCG-AEI could induce higher specific antibody titers and significantly increase cellular immune response than BCG, or rBCG-A strain (expressing Ag85B), or rBCG-AE strain (expressing fusion protein Ag85B-ESAT-6). The protective experiment demonstrated that rBCG-AEI could confer similar or even better protective efficacy against M. tuberculosis infection compared with others in organ bacterial loads, lung histopathology and net weight gain or loss. The results suggested that rBCG-AEI is a potential candidate for further study.

On the Linear Separability of Diagnostic Models (2006)

As new approaches and algorithms are developed for system diagnosis, it is important to reflect on existing approaches to determine their strengths and weaknesses. Of concern is identifying potential reasons for false pulls during maintenance. Within the aerospace community, one approach to system diagnosis-based on the D-matrix derived from test dependency modeling-is used widely, yet little has been done to perform any theoretical assessment of the merits of the approach. Past assessments have been limited, largely, to empirical analysis and case studies. In this paper, we provide a theoretical assessment of the representation power of the D-matrix and suggest algorithms and model types for which the D-matrix is appropriate. Finally, we relate the processing of the D-matrix with several diagnostic approaches and suggest how to extend the power of the D-matrix to take advantage of the power of those approaches.
Deterministically annealed mixture of experts models for statistical regression (2002)

A new and effective design method is presented for statistical regression functions that belong to the class of mixture models. The class includes the hierarchical mixture of experts (HME) and the normalized radial basis functions (NRBF). Design algorithms based on the maximum likelihood (ML) approach, which emphasize a probabilistic description of the model, have attracted much interest in HME and NRBF models. However, their design objective is mismatched to the original squared-error regression cost and the algorithms are easily trapped by poor local minima on the cost surface. In this paper, we propose an extension of the deterministic annealing (DA) method for the design of mixture-based regression models. We construct a probabilistic framework, but unlike the ML method, we directly optimize the squared-error regression cost, while avoiding poor local minima. Experimental results show that the DA method outperforms standard design methods for both HME and NRBF regression models.
A Model for Assured Software Download on Mobile Terminals (2009)

Over-the-air (OTA) software download is a key enabling technology for terminal reconfigurations. With increasing the number of network protocols, variety of software products with different software providers and new software threats, it becomes important to download and install assured software on the mobile terminals. Most of the related research works on downloading assured software, focus on software validation after download, and mainly on the terminal. In this paper, a model is proposed in which an assurance agency is exploited. This agency is responsible for performing software examination and validations. Unlike related work, examination and validation operations are centrally performed in the network before downloading the software. Based on a cost analysis, it is shown that the overhead of using the assurance agency in downloading scenario is acceptable.
The Isolation and Characterization of Murine Macrophages (2015)

Abstract Macrophages are mononuclear phagocytes that are widely distributed throughout the body. These cells can contribute to development and homeostasis and participate in innate and adaptive immune responses. The physiology of macrophages can vary tremendously depending on the environment in which they reside and the local stimuli to which they are exposed. Macrophages are prodigious secretory cells, and in that role can promote and regulate immune responses and contribute to autoimmune pathologies. Macrophages are highly phagocytic, and in this capacity have long been considered to be essential immune effector cells. The important roles of macrophages in maintaining homeostasis and in contributing to tissue remodeling and wound healing is sometimes overlooked because of their vital role in host defense. © 2015 by John Wiley & Sons, Inc.
Capacity analysis of dedicated fixed and mobile relay in LTE-Advanced cellular networks (2009)

In this paper, the spectrum efficiency for four scenarios: baseline, cell split, fixed relay and dedicated mobile relay on vehicle are analyzed and compared in terms of unified spectrum efficiency bps/Hz/km2. The theoretical expression is derived and the capacity is calculated by numerical integration based on the parameters for 3GPP LTE-advanced system. The deployment costs for different scenarios are also estimated based on the current real network. This comparison can clearly show the benefit and cost of different solutions, and this is helpful for the strategy making.
Limitation of the frequency stability by local oscillator phase noise: new investigations (2003)

In passive frequency standards where atoms have a permanent interaction with the probe signal, the local oscillator phase noise limits the short and medium term frequency stability. It has been shown that this spurious effect cannot be suppressed whenever there is any truncation in the spectrum of the resonator response. However, a simultaneous processing of the probe signal, similar to that of the NIST, and of the resonator response-by means of an appropriate demodulation waveform-makes it possible to significantly reduce the limiting effect. First achieved with a square wave frequency modulation, this result is now extended to various modulation waveforms. It is shown that, for various modulation waveforms, the use of an optimized demodulation provides a moderate additional improvement to a moderate 2f/sub M/ rejection: this result confirms that, for a cesium clock using a slow frequency modulation, a high 2f/sub M/ rejection and a proper demodulation are necessary to strongly reduce the limiting effect. It is also shown that a non controlled distortion in the demodulation waveform may degrade the performance. At last, for a square wave frequency modulation and in the case of a flicker phase noise, a convenient demodulation reduces the spurious effect by a few dBs without any rejection in the microwave spectrum.
A Multi-camera Approach to Vehicle Tracking Based on Features (2007)

Automobile detection based on feature tracking has proven effective in handling vehicle occlusions. However, current systems adopt a single camera to compute the 3D coordinates of feature points, which leads to an under-conditioned problem. As a result, only a few stable features can be reconstructed successfully. In this paper, we extend the system by adding a second camera, and integrate structure from motion (SfM) techniques to reconstruct a large volume of 3D points without sacrificing accuracy.

A Peptide-Based, Ratiometric Biosensor Construct for Direct Fluorescence Detection of a Protein Analyte (2008)

We present the design, synthesis, and functional evaluation of peptide-based fluorescent constructs for wavelength-ratiometric biosensing of a protein analyte. The concept was shown using the high-affinity model interaction between the 18 amino acid peptide pTMVP and a recombinant antibody fragment, Fab57P. pTMVP was functionalized in two different positions with 6-bromomethyl-2-(2-furanyl)-3-hydroxychromone, an environmentally sensitive fluorophore with a two-band emission. The equilibrium dissociation constant of the interaction between pTMVP and Fab57P was largely preserved upon labeling. The biosensor ability of the labeled peptide constructs was evaluated in terms of the relative intensity change of the emission bands from the normal (N*) and tautomer (T*) excited-state species of the fluorophore ( I(N*)/I(T*)) upon binding of Fab57P. When the peptide was labeled in the C terminus, the I(N*)/I(T*) ratio changed by 40% upon analyte binding, while labeling close to the residues most important for binding resulted in a construct that completely lacked ratiometric biosensor ability. Integrated biosensor elements for reagentless detection, where peptides and ratiometric fluorophores are combined to ensure robustness in both recognition and signaling, are expected to become an important contribution to the design of future protein quantification assays in immobilized formats.
Bayesian Inference for Generalized Additive Mixed Models Based on Markov Random Field Priors (2001)

SUMMARY Most regression problems in practice require flexible semiparametric forms of the predictor for modelling the dependence of responses on covariates. Moreover, it is often necessary to add random effects accounting for overdispersion caused by unobserved heterogeneity or for correlation in longitudinal or spatial data. We present a unified approach for Bayesian inference via Markov chain Monte Carlo simulation in generalized additive and semiparametric mixed models. Different types of covariates, such as the usual covariates with fixed effects, metrical covariates with non-linear effects, unstructured random effects, trend and seasonal components in longitudinal data and spatial covariates, are all treated within the same general framework by assigning appropriate Markov random field priors with different forms and degrees of smoothness. We applied the approach in several case-studies and consulting cases, showing that the methods are also computationally feasible in problems with many covariates and large data sets. In this paper, we choose two typical applications.

The focus of light--linear polarization breaks the rotational symmetry of the focal spot (2003)

We experimentally demonstrate for the first time that a linearly polarized beam is focussed to an asymmetric spot when using a high-numerical aperture focussing system.This asymmetry was predicted by Richards and Wolf [Proc.R. Soc.London A 253, 358 (1959)] and can only be measured when a polarization insensitive sensor is placed in the focal region.We used a specially modified photodiode in a knife edge type set up to obtain highly resolved images of the total electric energy density distribution at the focus.The results are in good agreement with the predictions of a vectorial focussing theory.
