Preparation of Gold Nanoparticles for Biomedical Applications Using Chemometric Technique (2013)

Purpose: To study the effect of process conditions on the size of gold nanoparticles (AuNPs) prepared by chemometric technique.Methods: AuNPs were prepared by adding 5 ml of 5 mM of gold (III) chloride hydrate HAuCl4 (2 mg/mL) to 85 ml of filtered deionized water, then refluxed in a 250 mL flask over a hot plate and heated to boiling point. Five milliliters of sodium citrate solution of varying concentrations were quickly added to the boiling solution and stirred for 30 min until the color turned to wine red. Chemometric approach, based on multivariant analysis, was applied to the optimization of iron oxide nanoparticle size in respect of three parameters, viz, concentration of sodium citrate solution, stirrer speed and ionic strength of the medium. The experiments were performed according to Box-Behnken experimental design.Results: The regression model obtained was characterized by both descriptive and predictive ability. The method was optimized with respect to average diameter as a response. The average diameter of the nanoparticles produced under different conditions were between 17.7 up to 168.8 nm. The criteria for the evaluation of the descriptive capability of a polynomial were R2 = 0.974, standard error = 13.994 and F-ratio = 18.4.Conclusion: It can be concluded that the Box-Behnken experimental design provides a suitable approach for optimizing and testing the robustness of gold nanoparticle preparation method.Keywords: Box-Behnken design, Optimization, Nanoparticles, Gold, Biomedical, Chemometric.
Amerasian Refugees: Social Characteristics, Service Needs, and Mental Health (1995)

Since 1983, more than 34,000 Amerasians and their 48,000 accompanying family members from Vietnam have been resettled in the United States of America. Having American fathers whose race and ethnicity are very differentfrom traditional Vietnamese, these children were considered outcasts by members of their own culture and,for the most part, led marginal lives in Vietnam. This article presents findings of a study conducted on a sample of 80 Amerasian refugees who have resettled in a large Southern city within the last two years. The study's intent was to identify the current social characteristics, service needs, and mental health status of the Amerasians. Implications for social work practice with Amerasians are also discussed.
Essential Oils: Extraction, Bioactivities, and Their Uses for Food Preservation (2014)

Essential oils are concentrated liquids of complex mixtures of volatile compounds and can be extracted from several plant organs. Essential oils are a good source of several bioactive compounds, which possess antioxidative and antimicrobial properties. In addition, some essential oils have been used as medicine. Furthermore, the uses of essential oils have received increasing attention as the natural additives for the shelf-life extension of food products, due to the risk in using synthetic preservatives. Essential oils can be incorporated into packaging, in which they can provide multifunctions termed "active or smart packaging." Those essential oils are able to modify the matrix of packaging materials, thereby rendering the improved properties. This review covers up-to-date literatures on essential oils including sources, chemical composition, extraction methods, bioactivities, and their applications, particularly with the emphasis on preservation and the shelf-life extension of food products.
Distance-based Multilayer Perceptrons (2000)

Neural network models are presented as special cases of a framework for general Similarity-Based Methods (SBMs). Distance-based multilayer perceptrons (D-MLPs) with non-Euclidean metric functions are described. D-MLPs evaluate similarity to prototypes making the interpretation of the results easier. Renormalization of the input data in the extended feature space brings dramatic changes in the shapes of decision borders. An illustrative example showing these changes is provided.
A Privacy-Preserving Method for Photo Sharing in Instant Message Systems (2017)

In instant messaging systems, photos have become an expressive form of real-time content sharing among users. Unfortunately, faces of stakeholders, who are depicted in the shared photos, may be exposed to unexpected viewers. This may lead to privacy leakages. In this paper, an approach is proposed to prevent such leakages, which is based on access control and face recognition. Each time a photo is sent, all stakeholders are recognized, and their faces are hidden from viewers. At the same time, stakeholders will be notified about the photo, and can decide to reveal their own faces to some proper viewers later. On the other hand, similar photos are exploited to automate this revealing process when possible, so as to reduce the impact of access control on user experiences. Besides, a proof-of-concept system is constructed and its performance is evaluated. The results indicate that this approach can be applied in instant messaging systems without too much overhead.

Chimeric G Proteins Extend the Range of Insect Cell-Based Functional Assays for Human G Protein-Coupled Receptors (2004)

We previously described a functional assay for G protein-coupled receptors (GPCRs) based on stably transformed insect cells and using the promiscuous G protein Galpha16. We now show that, compared with Galpha16, the use of chimeric Galphaq subunits with C-terminal modifications (qi5-HA, qo5-HA, or qz5-HA) significantly enhances the ability of insect cells to redirect Gi-coupled GPCRs into a Gq-type signal transduction pathway. We coexpressed human Gi-coupled GPCRs, G protein alpha subunits (either a chimeric Galphaq or Galpha16), and the calcium-sensitive reporter protein aequorin in Sf9 cells using a nonlytic protein expression system, and measured agonist-induced intracellular calcium flux using a luminometer. Three of the GPCRs (serotonin 1A, 1D, and dopamine D2) were functionally redirected into a Gq-type pathway when coexpressed with the chimeric G proteins, compared with only one (serotonin 1A) with Galpha16. We determined agonist concentration-response relationships for all three receptors, which yielded EC50 values comparable with those achieved in mammalian cell-based assay systems. However, three other Gi-coupled GPCRs (the opioid kappa1 and delta1 receptors, and serotonin 1E) were not coupled to calcium flux by either the G protein chimeras or Galpha16. Possible reasons and solutions for this result are discussed.
Reducing burn-in time through high-voltage stress test and Weibull statistical analysis (2006)

To guarantee an industry standard of reliability in ICs, manufacturers incorporate special testing techniques into the circuit manufacturing process. For most electronic devices, the specific reliability required is quite high, often producing a lifespan of several years. Testing such devices for reliability under normal operating conditions would require a very long period of time to gather the data necessary for modeling the device's failure characteristics. Under this scenario, a device might become obsolete by the time the manufacturer could guarantee its reliability. High-voltage stress testing (HVST) is common in IC manufacturing, but publications comparing it with other test and burn-in methods are scarce. This article shows that the use of HVST can dramatically reduce the amount of required burn-in.
Generation of highly tunable microwave radiation via a relativistic ionization front (2002)

A novel method of continuously upshifting the frequency of an electromagnetic wave is presented. This technique utilizes a relativistically propagating ionization front to simultaneously upshift and compress the source radiation. Using existing technology, it is possible to apply this technique to obtain a single source that is tunable from the microwave (30 GHz) to the millimeter (300 GHz) regime. Peak powers in the kilowatt range with pulse durations of much less than 1 ns are feasible. This technique has been demonstrated in a proof-in-principle experiment by upshifting 34.8-GHz radiation to greater than 116 GHz, with the degree of upshift being continuously tunable. The experimental arrangement employed a microwave cavity filled with azulene vapour. It should be possible to scale the technique to higher frequencies and higher powers.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Interpretive advantages of 90°-phase wavelets: Part 2 — Seismic applications (2005)

Abstract We examine field seismic data to test the benefits of 90°-phase wavelets in thin-bed interpretation that are predicted by seismic modeling in part 1 of this paper. In an interbedded sandstone-shale Miocene succession in the Gulf of Mexico basin, a 90°-phase shift of nearly zero-phase seismic data significantly improves lithologic and stratigraphic interpretation. A match between seismic and acoustic impedance (AI) profiles results in a better tie between seismic amplitude traces and lithology-indicative logs. Better geometric imaging of AI units that does not use dual-polarity seismic events results in easier and more accurate reservoir delineation. Less amplitude distortion and the stratigraphy-independent nature of thin-bed interference significantly improves stratigraphic resolution and seismic stratigraphic profiling. For a Ricker-like wavelet having small side lobes, stratigraphic resolution of 90°-phase data is considerably higher than that of zero-phase data. In this specific case, stratigraphic resolution of 90°-phase data is λ/4 (λ = wavelength), compared with λ/2 for its zero-phase counterpart. Stratal slices made from 90°-phase data show geomorphologic patterns of depositional systems with less noise and fewer interference fingerprints. A Permian Basin field provides a real-world example of porous zones in thin, high-frequency carbonate sequences that are better visualized with 90°-phase seismic data than with zero-phase data. =
Comprehensive Functional Annotation of Seventy-One Breast Cancer Risk Loci (2013)

Breast Cancer (BCa) genome-wide association studies revealed allelic frequency differences between cases and controls at index single nucleotide polymorphisms (SNPs). To date, 71 loci have thus been identified and replicated. More than 320,000 SNPs at these loci define BCa risk due to linkage disequilibrium (LD). We propose that BCa risk resides in a subgroup of SNPs that functionally affects breast biology. Such a shortlist will aid in framing hypotheses to prioritize a manageable number of likely disease-causing SNPs. We extracted all the SNPs, residing in 1 Mb windows around breast cancer risk index SNP from the 1000 genomes project to find correlated SNPs. We used FunciSNP, an R/Bioconductor package developed in-house, to identify potentially functional SNPs at 71 risk loci by coinciding them with chromatin biofeatures. We identified 1,005 SNPs in LD with the index SNPs (r(2)≥0.5) in three categories; 21 in exons of 18 genes, 76 in transcription start site (TSS) regions of 25 genes, and 921 in enhancers. Thirteen SNPs were found in more than one category. We found two correlated and predicted non-benign coding variants (rs8100241 in exon 2 and rs8108174 in exon 3) of the gene, ANKLE1. Most putative functional LD SNPs, however, were found in either epigenetically defined enhancers or in gene TSS regions. Fifty-five percent of these non-coding SNPs are likely functional, since they affect response element (RE) sequences of transcription factors. Functionality of these SNPs was assessed by expression quantitative trait loci (eQTL) analysis and allele-specific enhancer assays. Unbiased analyses of SNPs at BCa risk loci revealed new and overlooked mechanisms that may affect risk of the disease, thereby providing a valuable resource for follow-up studies.
A practical tool for monitoring the performance of measuring systems in a laboratory network: report of an ACB Working Group (2017)

Background A logical consequence of the introduction of robotics and high-capacity analysers has seen a consolidation to larger units. This requires new structures and quality systems to ensure that laboratories deliver consistent and comparable results. Methods A spreadsheet program was designed to accommodate results from up to 12 different instruments/laboratories and present IQC data, i.e. Levey-Jennings and Youden plots and comprehensive numerical tables of the performance of each item. Input of data was made possible by a 'data loader' by which IQC data from the individual instruments could be transferred to the spreadsheet program on line. Results A set of real data from laboratories is used to populate the data loader and the networking software program. Examples are present from the analysis of variance components, the Levey-Jennings and Youden plots. Conclusions This report presents a software package that allows the simultaneous management and detailed monitoring of the performance of up to 12 different instruments/laboratories in a fully interactive mode. The system allows a quality manager of networked laboratories to have a continuous updated overview of the performance. This software package has been made available at the ACB website.
A Triple Estimating Receiver of Multiplexed Binary Offset Carrier (MBOC) Modulated Signals (2008)

Multiplexed Binary Offset Carrier (MBOC) is an
important development of the BOC principle. But there is
a tracking problem in realising a BOC receiver by a
conventional implementation. For BOC this problem has
been characterised as that of ‘false lock’. Here a different
point of view identifies the problem as a limited capture
range (compared to an equivalent PSK). This problem is
exacerbated in the case of MBOC. A radically different
approach described here solves the problem by adopting
what we name as a triple estimating receiver. Three
complementary estimates of the time of arrival (TOA) of
the input signal are generated: a lowest accuracy but
unambiguous estimate responding purely to the code
modulation; and two higher accuracy but integerambiguous
estimates responding purely to the two
component sub-carrier modulations. The code estimate is
used to integer correct the lower resolution sub-carrier
estimates which in turn integer corrects the higher
resolution estimate. A weighted linear combination
provides a signal-to- noise optimal single estimate. The
full range capture capability is available because there is
never any false lock condition and the full potential
accuracy of MBOC is realised. Implementation is by a
quadruple loop rather than the double loop conventional
receivers.
Deploying Cognitive Radio: Economic, Legal and Policy Issues (2008)

Over the past decade, the demand by commercial, military and consumers for use of the electromagnetic spectrum has literally exploded. The most obvious examples are digital cellular telephony and WiFi, both of which have become ubiquitous in developed and less developed countries around the world within a very short time. And there is no indication that this growth in spectrum-dependent technology will abate soon. Tracking devices, machines that can “talk” to one another, exchanging information, are being deployed as we speak. Unfortunately, the systems we use in the US and worldwide to allocate and manage spectrum is bending under the strain these demands place on the system. Government allocation of spectrum, either by “beauty contests” (traditional) or auction (more recent) has failed to keep up with the growth in demand. Even worse, government allocation has led to an extraordinarily inefficient use of this valuable resource. Large swathes of spectrum are underutilized and beyond our reach even while the demand for wireless voice and data services strains existing wireless providers beyond their capacity.
Recessed source/drain for sub-50 nm UTB SOI MOSFET (2007)

In this work, the recessed source/drain (ReS/D) ultra-thin body (UTB) SOI MOS transistor is investigated in detail. Results reveal that the ReS/D structure provides UTB devices with much lower source/drain series resistance than the elevated source/drain (E-S/D) one and thereby alleviates the critical requirement for low contact resistivity of sub-50 nm generations. On the other hand, the ReS/D devices do not exhibit the degraded short channel effect immunity compared to the E-S/D devices. The design guidelines and window for the ReS/D devices are also suggested in terms of the simulation results. It is thus demonstrated that the ReS/D approach is capable of accelerating SOI device scaling down to 10 nm node.
Analytical families of two-component anisotropic polytropes and their relativistic extensions (2013)

In this paper, we study a family of two-component anisotropic polytropes which model a wide range of spherically symmetric astrophysical systems such as early-type baryonic galaxies. This family is found to contain a large class of models such as the hypervirial family (which satisfy the virial theorem locally), the Plummer and Hernquist models and Navarro-Frenk-White (NFW) like models. The potential–density pair for these models are derived, as well as their velocity dispersions and anisotropy parameters. The projected quantities are computed and found to reduce to analytical expressions in some cases. The first section of this paper presents an extension of the two-term anisotropic polytropes to encompass a very wide range of potential–density pairs. In the next section, we present the general relativistic extension of the potential–density pair and calculate the stress–energy tensor, the relativistic anisotropy parameter, the velocity of circular orbits and the angular momentum. Remarkably, for the case of the hypervirial family, the relativistic pressure in the Newtonian limit and the relativistic anisotropy parameter are found to coincide with the corresponding Newtonian expressions. The weak, dominant and strong energy conditions are found to be satisfied only for a certain range of the free parameters. We show that the relativistic hypervirial family also has a finite total mass like its Newtonian counterpart. In the first appendix, a relativistic extension of a different hypervirial family of models is studied and the relativistic anisotropy parameter is found to coincide with the Newtonian one. Finally, we present a family of models obtained from our distribution function that are similar to the Ossipkov–Merritt models; by computing their anisotropy parameters, we show that they model systems with isotropic cores and radially anisotropic exteriors.

Automated Inspection of Defects in Optical Fiber Connector End Face Using Novel Morphology Approaches (2018)

Increasing deployment of optical fiber networks and the need for reliable high bandwidth make the task of inspecting optical fiber connector end faces a crucial process that must not be neglected. Traditional end face inspections are usually performed by manual visual methods, which are low in efficiency and poor in precision for long-term industrial applications. More seriously, the inspection results cannot be quantified for subsequent analysis. Aiming at the characteristics of typical defects in the inspection process for optical fiber end faces, we propose a novel method, “difference of min-max ranking filtering” (DO2MR), for detection of region-based defects, e.g., dirt, oil, contamination, pits, and chips, and a special model, a “linear enhancement inspector” (LEI), for the detection of scratches. The DO2MR is a morphology method that intends to determine whether a pixel belongs to a defective region by comparing the difference of gray values of pixels in the neighborhood around the pixel. The LEI is also a morphology method that is designed to search for scratches at different orientations with a special linear detector. These two approaches can be easily integrated into optical inspection equipment for automatic quality verification. As far as we know, this is the first time that complete defect detection methods for optical fiber end faces are available in the literature. Experimental results demonstrate that the proposed DO2MR and LEI models yield good comprehensive performance with high precision and accepted recall rates, and the image-level detection accuracies reach 96.0 and 89.3%, respectively.
