Transparent Conductive Oxide Layer and Hole Selective Layer Free Back-Contacted Hybrid Perovskite Solar Cell (2017)

Back-contacted architectures have been under intensive investigation for that transparent conductive oxide (TCO) less solar cells (SCs) can be easily realized which avoid the transmission loss of light caused by TCO, typically comprised in conventional solar cells. Here, network-like porous Ti was first utilized as the back-contacted electrode, and a new design allows for a novel back-contacted hybrid perovskite SC without TCO and hole selective layer, which shows a power output of 3.88% with long-term stability. In addition, it avoids limit available collection area of electrodes in the recent reported interdigitated electrode (IDE) based back-contacted TCO-less SCs.
A novel face recognition system using hybrid neural and dual eigenspaces methods (2002)

In this paper, we present an automated face recognition (AFR) system that contains two components: eye detection and face recognition. Based on invariant radial basis function (IRBF) networks and knowledge rules of facial topology, a hybrid neural method is proposed to localize human eyes and segment the face region from a scene. A dual eigenspaces method (DEM) is then developed to extract algebraic features of the face and perform the recognition task with a two-layer minimum distance classifier. Experimental results illustrate that the proposed system is effective and robust.
Scene Adaptive Cosmetic Makeup Transfer (2018)

Cosmetic makeup is an art in itself which people use to often enhance their beauty and express themselves. Putting on makeup is a tedious task, so who would not love to see themselves in makeup before physically applying it? In this work, we demonstrate the transfer of makeup from a reference makeup image to some subject image. Our technique involves generation and use of 3D face models of these images. Some nice features of our pipeline include: (1) process adapts to the lighting conditions of the subject image. (2) after makeup on subject image, it is possible to view it in different indoor and outdoor lighting conditions. (3) accessories can be added realistically with proper lighting so that they naturally fit in the subject's scene.
A polymorphism in the <i>NPPA</i> gene associates with asthma (2008)

For rs5067, the risks of asthma in carriers of the C allele in the screening and replicate cohorts were reduced by 50% and 76%, respectively. NPPA may be an important susceptibility gene for asthma.
Compared pharmacology of human histamine H<sub>3</sub>and H<sub>4</sub>receptors: structure–activity relationships of histamine derivatives (2006)

Various histamine derivatives were investigated at the human H3 receptor (H3R) and H4 receptor (H4R) stably expressed in human embryonic kidney (HEK)-293 cells using [125I]iodoproxyfan and [3H]histamine binding, respectively. In Tris buffer, [3H]histamine binding to membranes of HEK(hH4R) cells was monophasic (K(D) of 3.8+/-0.8 nM). In phosphate buffer, the Hill coefficient was decreased (n(H) = 0.5+/-0.1) and a large fraction of the binding was converted into a low-affinity component (K(D) = 67+/-27 nM). The inhibition of [3H]histamine binding by two agonists, a protean agonist and five antagonists/inverse agonists confirms that the potency of many H3R ligands is retained or only slightly reduced at the H4R. Histamine derivatives substituted with methyl groups in alpha, beta or N(alpha) position of the side chain retained a nanomolar potency at the H3R, but their affinity was dramatically decreased at the H4R. With relative potencies to histamine of 282 and 0.13% at the H3R and H4R, respectively, (+/-)-alpha,beta-dimethylhistamine is a potent and selective H3R agonist. Chiral alpha-branched analogues exhibited a marked stereoselectivity at the H3R and H4R, the enantiomers with a configuration equivalent to L-histidine being preferred at both receptors. The methylsubstitution of the imidazole ring was also studied. The relative potency to histamine of 4-methylhistamine (4-MeHA) at the H4R (67%) was similar to that reported at H2 receptors but, owing to its high affinity at the H4R (Ki = 7.0+/-1.2 nM) and very low potency at H1- and H3-receptors, it can be considered as a potent and selective H4R agonist. On inhibition of forskolin-induced cAMP formation, all the compounds tested, including 4-MeHA, behaved as full agonists at both receptors. However, the maximal inhibition achieved at the H4R (approximately -30%) was much lower than at the H3R (approximately -80%). Thioperamide behaved as an inverse agonist at both receptors and increased cAMP formation with the same maximal effect (approximately +25%). In conclusion, although the pharmacological profiles of the human H3R and H4R overlap, the structure-activity relationships of histamine derivatives at both receptors strongly differ and lead to the identification of selective compounds.
Robust Secrecy Beamforming With Energy-Harvesting Eavesdroppers (2014)

This letter considers simultaneous wireless information and power transfer (SWIPT) in multiple-input-single-output downlink systems in which a multiantenna transmitter sends a secret message to a single-antenna information receiver (IR) with multiple single-antenna energy receivers (ERs). We aim to maximize the harvested energy by the ERs while maintaining the signal-to-interference-and-noise ratio (SINR) threshold at the IR and keeping the message secure from possible eavesdropping by the ERs by suppressing their SINRs. Both scenarios of perfect and imperfect channel state information at the transmitter are studied. Using semidefinite relaxation techniques, we show that there always exists a rank-one optimal solution for the IR, i.e., transmit beamforming is optimal for the IR.
Anti-inflammatory activities of <i>Echinacea</i> extracts do not correlate with traditional marker components (2009)

Numerous preparations of Echinacea (Asteraceae), mainly derived from three species, Echinacea purpurea ( L.) Moench, Echinacea angustifolia (D.C.) and Echinacea pallida (Nutt.) Nutt., are available for the treatment of symptoms of colds and influenza which, along with a number of other respiratory conditions, have been ascribed to the induction of pro-inflammatory cytokines. We evaluated various chemically characterized extracts and fractions, derived from the three species of Echinacea, for their possible inhibitory effects on the secretion of pro-inflammatory cytokines IL-6 and IL-8 (CXCL-8) by human bronchial epithelial cells infected with rhinovirus type 14. All of the E. purpurea fractions, comprising aqueous or ethanol extracts of roots, leaves and stems, but to a lesser degree flowers, strongly inhibited the secretion of both cytokines. In contrast, corresponding fractions derived from E. angustifolia and E. pallida showed relatively weak cytokine-inhibitory activity, whereas their aqueous fractions significantly enhanced cytokine secretion, both in virus-infected and in uninfected cells. These properties did not correlate with the presence or absence of alkylamides or specific caffeic acid derivatives, although the alkylamide rich fraction of E. angustifolia showed a significant inhibitory effect. However, there was some correlation between anti-cytokine effects and our previously reported anti-viral activities. Thus, none of the groups of compounds traditionally used as “markers” for Echinacea are responsible for anti-inflammatory activity. Consequently, we believe that other constituents of Echinacea should be evaluated.
Predicting candidate genomic sequences that correspond to synthetic functional RNA motifs (2005)

Riboswitches and RNA interference are important emerging mechanisms found in many organisms to control gene expression. To enhance our understanding of such RNA roles, finding small regulatory motifs in genomes presents a challenge on a wide scale. Many simple functional RNA motifs have been found by in vitro selection experiments, which produce synthetic target-binding aptamers as well as catalytic RNAs, including the hammerhead ribozyme. Motivated by the prediction of Piganeau and Schroeder [(2003) Chem. Biol., 10, 103-104] that synthetic RNAs may have natural counterparts, we develop and apply an efficient computational protocol for identifying aptamer-like motifs in genomes. We define motifs from the sequence and structural information of synthetic aptamers, search for sequences in genomes that will produce motif matches, and then evaluate the structural stability and statistical significance of the potential hits. Our application to aptamers for streptomycin, chloramphenicol, neomycin B and ATP identifies 37 candidate sequences (in coding and non-coding regions) that fold to the target aptamer structures in bacterial and archaeal genomes. Further energetic screening reveals that several candidates exhibit energetic properties and sequence conservation patterns that are characteristic of functional motifs. Besides providing candidates for experimental testing, our computational protocol offers an avenue for expanding natural RNA's functional repertoire.

On the relationship of node capacity distribution and P2P topology formation (2005)

In heterogeneous peer-to-peer (P2P) networks, node capacity distribution becomes a critical parameter in topology formation. Many measurement studies on P2P file-sharing systems point out that users' bandwidths are actually very diverse, from 56 Kbps modem connections to a few Mbps cable modem connections. Thus, the capacity factor cannot be ignored in the formation of P2P networks. The contribution of this paper is twofold. First, we propose a simple protocol for building P2P topologies such that the connectivity of each peer is based on their capacities to achieve load-balancing. The basic idea for the protocol is to use random walk to assist new incoming peers in selecting their neighbors with a high capacity. This random walk algorithm only relies on local information., and thus is fully distributed. Second, by mathematical analysis and simulations, we investigate the performance of the proposed protocol and show that the topology structure depends heavily on the capacity distribution of the users. The analytical results provide insightful guidelines for overlay network modeling, planning and protocol design based on the node capacity distribution. To the best of our knowledge, this is the first paper that analyzes this relationship.
Specification of Software Quality Attributes. Volume 2. Software Quality Specification Guidebook. (1985)

Abstract : The document is the first of three volumes of the Final Technical Report for the Specification of Software Quality Attributes contract. The purpose of this contract was to (1) consolidate results of previous RADC contracts dealing with software quality measurement, (2) enhance the software quality framework, and (3) develop a methodology to enable a software acquisition manager to determine and specify software quality factors requirements. The methodology and framework elements was developed to focus on an Air Force software acquisition manager specifying quality requirements for embedded software that is part of a command and control application. This methodology and most of the framework elements are generally useful for other applications and different environments. Volumes II and II describe the methodology for using the metrics technology and include an overview of the software acquisition process using this technology and quality framework. Volume III describes methods for evaluating achieved quality levels of software products and addresses the needs of data collection and analysis personnel. Volume III also describes procedures and techniques for evaluating achieved quality levels of software products. Worksheets for collecting metric data by software lifecycle phase and score sheets for scoring each factor are provided in the appendixes. Detailed metric questions are nearly identical to questions in the Software Evaluation Reports proposed as part of the Software Technology for Adaptable Reliable Systems (STARS) Measurement data item descriptions.
Cell-autonomous light sensitivity via Opsin3 regulates fuel utilization in brown adipocytes (2020)

Opsin3 (Opn3) is a transmembrane heptahelical G protein-coupled receptor (GPCR) with the potential to produce a nonvisual photoreceptive effect. Interestingly, anatomical profiling of GPCRs reveals that Opn3 mRNA is highly expressed in adipose tissue. The photosensitive functions of Opn3 in mammals are poorly understood, and whether Opn3 has a role in fat is entirely unknown. In this study, we found that Opn3-knockout (Opn3-KO) mice were prone to diet-induced obesity and insulin resistance. At the cellular level, Opn3-KO brown adipocytes cultured in darkness had decreased glucose uptake and lower nutrient-induced mitochondrial respiration than wild-type (WT) cells. Light exposure promoted mitochondrial activity and glucose uptake in WT adipocytes but not in Opn3-KO cells. Brown adipocytes carrying a defective mutation in Opn3's putative G protein-binding domain also exhibited a reduction in glucose uptake and mitochondrial respiration in darkness. Using RNA-sequencing, we identified several novel light-sensitive and Opn3-dependent molecular signatures in brown adipocytes. Importantly, direct exposure of brown adipose tissue (BAT) to light in living mice significantly enhanced thermogenic capacity of BAT, and this effect was diminished in Opn3-KO animals. These results uncover a previously unrecognized cell-autonomous, light-sensing mechanism in brown adipocytes via Opn3-GPCR signaling that can regulate fuel metabolism and mitochondrial respiration. Our work also provides a molecular basis for developing light-based treatments for obesity and its related metabolic disorders.
On the design of energy efficient optical networks with Software Defined Networking control across core and access networks (2013)

This paper presents a Software Defined Networking (SDN) control plane based on an overlay GMPLS control model. The SDN control platform manages optical core networks (WDM/DWDM networks) and the associated access networks (GPON networks), which makes it possible to gather global information and enable wider areas' energy efficiency networking. The energy related information of the networks and the types of the traffic flows are collected and utilized for the end-to-end QoS provision. Dynamic network simulation results show that by applying different routing algorithms according to the type of traffic in the core networks, the energy efficiency of the network is improved without compromising the quality of service.

Field Test Results Demonstrating Improved Real-Time Data Quality in an Advanced LWD Acoustic System (2001)

Abstract Acoustic compressional slowness measurements are critical for geomechanics, petrophysical and seismic applications. Conventional acoustic wireline data is often unavailable due to cost constraints or well problems, thus increasing the need for acoustic Logging While Drilling (LWD). The LWD environment creates additional demands on borehole acoustic measurements as compared to wireline, due to tool strength requirements and drilling noise. These issues have consistently limited the LWD acoustic tool's ability to provide wireline equivalent data quality. The conventional LWD methods have incorporated single direction or single axis acoustic systems with short transmitter-receiver (TR) spacing (typically 4 ft). Technical features of a new acoustic LWD tool incorporating long TR spacing (+10 ft) with an array containing six four-element receiver stations to obtain omni-directional measurements will be discussed. Field test data examples will show the improved quality of this real-time measurement. The tool configuration was optimized as a result of comprehensive modeling and lab testing of key system components. Greater source power combined with multi-frequency adjustable signature capability allowed the TR spacing increase. The system quality was enhanced due to improved software and hardware functionality. An improved receiver array configuration allows for better noise isolation and response to formation arrivals. In addition, real-time downhole monitoring of the drilling noise coupled directly into the collar allows for further data quality enhancement. Redundancy and a modular design approach were key for providing a robust and reliable system with fast tool setup and data downloading. The field test examples will present data acquired in different drilling modes to demonstrate the improved signal-to-noise ratio for raw and stacked data in both fast and slow formations. As compared to industry standards, faster Rate of Penetration (ROP) is achievable due to enhanced downhole processing capabilities. The real time slowness results compared to conventional wireline shows the systems' ability to make comparable measurements. These field test results demonstrate an improved data quality with this new LWD acoustic system.
Carbon Dioxide Clathrate in the Martian Ice Cap (1970)

Measurements of the dissociation pressure of carbon dioxide hydrate show that this hydrate (CO(2) . 6H(2)O) is stable relative to solid CO(2) and water ice at temperatures above about 121 degrees K. Since this hydrate forms from finely divided ice and gaseous CO(2) in several hours at 150 degrees K, it is likely to be present in the martian ice cap. The ice cap can consist of water ice, water ice + CO(2) hydrate, or CO(2) hydrate + solid CO(2), but not water ice + solid CO(2).

Building multi-level planar maps integrating LRF, stereo vision and IMU sensors (2007)

Building maps of the explored environment during a rescue application is important in order to locate the information acquired through robot sensors. A lot of work has been done on mapping 2D large environments, while the creation of 3D maps is still limited to simple and small environments, due to the costs of 3D sensors and of high computational requirements. In this paper we analyze the problem of building multi-level planar maps. These maps are useful when mapping large indoor environments (e.g., a multi-floor building) and can be effectively created by integrating robustness and efficiency of state-of-the-art 2D SLAM techniques using 2D laser range finder data, with the use of a precise IMU sensor and effective visual odometry techniques based on stereo vision for measuring plane displacements. The main advantages of the proposed solution, with respect to other kinds of 3D maps, are the low-cost of the sensors mounted on the robots and the possibility of exploiting results from 2D SLAM for exploring very large environments. Preliminary experimental results show the effectiveness of the proposed approach.
A Reductions Approach to Fair Classification (2018)

We present a systematic approach for achieving fairness in a binary classification setting. While we focus on two well-known quantitative definitions of fairness, our approach encompasses many other previously studied definitions as special cases. The key idea is to reduce fair classification to a sequence of cost-sensitive classification problems, whose solutions yield a randomized classifier with the lowest (empirical) error subject to the desired constraints. We introduce two reductions that work for any representation of the cost-sensitive classifier and compare favorably to prior baselines on a variety of data sets, while overcoming several of their disadvantages.
Pharmacokinetics and Tissue Distribution of Recombinant Human Alpha A, D, A/D(Bgl), and I Interferons and Mouse Alpha-Interferon in Mice (1986)

The pharmacokinetics and tissue distribution in mice of several recombinant human alpha-interferons [rHuIFN-alpha A, D, I, and A/D(Bgl)] as well as natural mouse alpha-interferon (MuIFN-alpha) were assessed following single intravenous injections. The serum profiles of rHuIFN-alpha A, rHuIFN-alpha D, rHuIFN-alpha A/D(Bgl), and MuIFN-alpha were similar, whereas those following rHuIFN-alpha I showed a much longer terminal elimination phase. Differences in elimination half-life, volume of distribution, and total body clearance between these IFNs were observed. There was appreciable uptake of IFN in the kidney: the amount of each interferon per gram of tissue in the kidney ranges from 1 to 9 times the amount found in the serum. The greatest uptake appeared with rHuIFN-alpha D, followed by rHuIFN-alpha A, rHuIFN-alpha A/D(Bgl), and MuIFN-alpha. The only exception was rHuIFN-alpha I which showed no uptake into the kidney.
User Acceptance of Mobile Payments: A Theoretical Model for Mobile Payments (2005)

Mobile payment refers to the use of mobile devices to conduct payment transactions. Users can use mobile devices for remote and proximity payments; moreover, they can purchase digital contents and physical goods and services. It offers an alternative payment method for consumers. However, there are relative low adoption rates in this payment method. This research aims to identify and explore key factors that affect the decision of whether to use mobile payments. Two well-established theories, the Technology Acceptance Model (TAM) and the Innovation Diffusion Theory (IDT), are applied to investigate user acceptance of mobile payments. Survey data from mobile payments users will be used to test the proposed hypothesis and the model.
