Cooperative Positioning Techniques for Mobile Localization in 4G Cellular Networks (2007)

In this paper, we exploit the concept of cooperative localization by utilizing the additional information obtained from short-range links to enhance the location estimation accuracy in forthcoming cellular systems. Simulations for a hybrid WiMAX/Wi-Fi system are carried out considering an outdoor environment, where time difference of arrival (TDOA) and received signal strength (RSS) measurements are combined thanks to advanced data fusion techniques. Results show that the proposed system allows to meet the federal Communications Commission (FCC) requirements and overcome the ever changing channel conditions.

Predicting faults from cached history (2008)

We analyze the version history of 7 software systems to predict the most fault prone entities and files. The basic assumption is that faults do not occur in isolation, but rather in bursts of several related faults. Therefore, we cache locations that are likely to have faults: starting from the location of a known (fixed) fault, we cache the location itself, any locations changed together with the fault, recently added locations, and recently changed locations. By consulting the cache at the moment a fault is fixed, a developer can detect likely fault-prone locations. This is useful for prioritizing verification and validation resources on the most fault prone files or entities. In our evaluation of seven open source projects with more than 200,000 revisions, the cache selects 10% of the source code files; these files account for 73%-95% of faults--a significant advance beyond the state of the art
Characterization of electronic and optical properties of device quality <i>a</i>-Si:H and <i>a</i>-(Si,Ge):H grown by remote plasma electron cyclotron resonance deposition (1991)

The electronic and optical properties of device quality a-Si:H and a-(Si,Ge):H films grown by remote plasma electron cyclotron resonance (ECR) deposition were studied together with the plasma characteristics during growth. 100–350 W microwave plasmas, which were formed by introducing hydrogen and helium into the ECR chamber, were used to decompose silane and germane downstream of the ECR source. Use of hydrogen allows selective etching of the growth surface by reactive ion species. The plasma properties near the deposition surface are characterized using movable plane and cylindrical Langmuir probes and are correlated with the light and dark photoconductivity, optical gap, stability, and silicon–hydrogen bonding distribution of the deposited film in an effort to understand the influence that plasma species have on film quality.

Lipoxin A4 and Aspirin-Triggered 15-Epi-Lipoxin A4 Antagonize TNF-α-Stimulated Neutrophil-Enterocyte Interactions In Vitro and Attenuate TNF-α-Induced Chemokine Release and Colonocyte Apoptosis in Human Intestinal Mucosa Ex Vivo (2001)

Lipoxins (LXs) are lipoxygenase-derived eicosanoids and putative endogenous braking signals for inflammation in the gastrointestinal tract and other organs. Aspirin triggers the production of 15-epimers during cell-cell interaction in a cytokine-primed milieu, and aspirin-triggered 15-epi-5(S),6(R),15(S)-trihydroxy-7,9,13-trans-11-cis-eicosatetraenoic acid (15-epi-LXA(4)) may contribute to the bioactivity profile of this prototype nonsteroidal anti-inflammatory drug in vivo. We determined the effect of LXA(4), 15-(R/S)-methyl-11,12-dehydro-LXA(4) methyl ester (15-(R/S)-methyl-LXA(4)), and stable analogs of LXA(4) on TNF-alpha-stimulated neutrophil-enterocyte interaction in vitro and TNF-alpha-stimulated chemokine release, changes in mucosal architecture, and enterocyte apoptosis in cytokine-activated intact human colonic mucosa ex vivo. LXA(4), 15-(R/S)-epi-LXA(4), and 16-phenoxy-11,12-dehydro-17,18,19,20-tetranor-LXA(4) methyl ester (16-phenoxy-LXA(4)) inhibited TNF-alpha-stimulated neutrophil adherence to epithelial monolayers at nanomolar concentrations. In parallel experiments involving human colonic mucosa ex vivo, LXA(4)potently attenuated TNF-alpha-stimulated release of the C-X-C chemokine IL-8, and the C-C chemokines monocyte-chemoattractant protein-1 (MCP-1) and RANTES. Exposure of strips of normal human colonic mucosa to TNF-alpha induced disruption of mucosa architecture and enhanced colonocyte apoptosis via a caspase-3-independent mechanism. Prior exposure of the mucosa strips to 15-(R/S)-methyl-LXA(4) attenuated TNF-alpha-stimulated colonocyte apoptosis and protected the mucosa against TNF-alpha-induced mucosal damage. In aggregate, our data demonstrate that lipoxins and aspirin-triggered 15-epi-LXA(4) are potent antagonists of TNF-alpha-mediated neutrophil-enterocyte interactions in vitro, attenuate TNF-alpha-triggered chemokine release and colonocyte apoptosis, and are protective against TNF-alpha-induced morphological disruption in human colonic strips ex vivo. Our observations further expand the anti-inflammatory profile of these lipoxygenase-derived eicosanoids and suggest new therapeutic approaches for the treatment of inflammatory bowel disease.
Synthesis of binary sequences with good autocorrelation and crosscorrelation properties by simulated annealing (1996)

Simulated annealing is a statistical computational technique for obtaining approximate solutions to combinatorial optimization problems. An efficient simulated annealing algorithm is used to design binary sequence sets which have good autocorrelation and crosscorrelation properties. Some of the synthesized results are presented, and their properties are better than any other known in the literature. The synthesized binary sequence sets promise to be practically applicable.
PLASMA TRIGLYCERIDE AS A RISK FACTOR FOR CORONARY HEART DISEASE (1989)

Elevated plasma triglyceride has been found to be a univariate risk factor for coronary heart disease in many epidemiologic studies, but this increased risk is not independent of other lipid and lipoprotein measures. Rather than dismiss triglyceride as a risk factor, we can see this disparity between univariate and multivariate results as a clue to better understanding of the potential role of triglyceride in atherosclerosis. From a statistical point of view, triglyceride often is not a significant predictor of coronary heart disease in multivariate statistical models because of the large variation in triglyceride measurements and the strong inverse relation between HDL cholesterol and triglyceride. Heterogeneity in both the biologic mechanisms producing hypertriglyceridemia and the manifestations of cardiovascular disease complicates the study of triglyceride as a risk factor. recently, subclasses of both HDL and LDL have been shown to be related to triglyceride metabolism and may provide more precise variables for predicting risk. However, none of this evidence precludes the involvement of triglyceride in the development of atherosclerosis. The final answer as to whether triglyceride is a causal risk factor for coronary heart disease must come from the biologic sciences, and the complexity of the epidemiologic results likely reflects the intricate metabolic processes involved.

The origins of the models are discussed, and the two models are compared and contrasted.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
End-to-End Instance Segmentation and Counting with Recurrent Attention. (2016)

While convolutional neural networks have gained impressive success recently in solving structured prediction problems such as semantic segmentation, it remains a challenge to differentiate individual object instances in the scene. Instance segmentation is very important in a variety of applications, such as autonomous driving, image captioning, and visual question answering. Techniques that combine large graphical models with low-level vision have been proposed to address this problem; however, we propose an end-to-end recurrent neural network (RNN) architecture with an attention mechanism to model a human-like counting process, and produce detailed instance segmentations. The network is jointly trained to sequentially produce regions of interest as well as a dominant object segmentation within each region. The proposed model achieves state-of-the-art results on the CVPPP leaf segmentation dataset and KITTI vehicle segmentation dataset.
Characterization of mesenchymal stem cells from human vocal fold fibroblasts (2010)

Based on our findings, hVFF derived from lamina propria have the same cell surface markers, immunophenotypic characteristics, and differentiation potential as BM- and AT-derived MSCs. We propose that vocal fold fibroblasts are MSCs resident in the vocal fold lamina propria.
Improving the Efficiency of Conventional Spark-Ignition Engines Using Octane-on-Demand Combustion - Part II: Vehicle Studies and Life Cycle Assessment (2016)

<div class="section abstract"><div class="htmlview paragraph">This paper is the second of a two part study which investigates the use of advanced combustion modes as a means of improving the efficiency and environmental impact of conventional light-duty vehicles. This second study focuses on drive cycle simulations and Life Cycle Assessment (LCA) for vehicles equipped with Octane-on-Demand combustion. Methanol is utilized as the high octane fuel, while three alternative petroleum-derived fuels with Research octane numbers (RONs) ranging from 61 to 90 are examined as candidates for the lower octane fuel.</div><div class="htmlview paragraph">The experimental engine calibration maps developed in the previous study are first provided as inputs to a drive cycle simulation tool. This is used to quantify the total fuel consumption, octane requirement and tank-to-wheel CO<sub>2</sub> emissions for a light-duty vehicle equipped with two alternative powertrain configurations. The properties of the lower octane fuel are shown to affect the vehicle fuel consumption and CO<sub>2</sub> emissions significantly. In particular, the lower octane fuel indirectly defines the evolution of several key fuel properties with engine load. This synergistic relationship ultimately presents a trade-off between minimizing the vehicle fuel consumption and CO<sub>2</sub> emissions.</div><div class="htmlview paragraph">Finally, the well-to-tank CO<sub>2</sub> emissions arising from the production and distribution of each fuel were estimated for several common feedstocks and production routes. This data was combined with the tank-to-wheel CO<sub>2</sub> emissions to estimate the overall carbon intensity of each dual-fuel combination using a Life Cycle Assessment. This enables the broader benefits and practical challenges to be analyzed from the perspective of a range of stakeholders. Overall, this work suggests that Octane-on-Demand can provide considerable fuel economy and well-to-wheel CO<sub>2</sub> emissions benefits in comparison with conventional light-duty vehicles operated on standard gasolines.</div></div>

Augmented Reality: An Overview and Five Directions for AR in Education (2011)

Augmented Reality (AR) is an emerging form of experience in which the Real World (RW) is enhanced by computer-generated content tied to specific locations and/or activities. Over the last several years, AR applications have become portable and widely available on mobile de­vices. AR is becoming visible in our audio-visual media (e.g., news, entertainment, sports) and is beginning to enter other aspects of our lives (e.g., e-commerce, travel, marketing) in tangible and exciting ways. Facilitating ubiquitous learning, AR will give learners instant access to location-specific information compiled and provided by numerous sources (2009). Both the 2010 and 2011 Horizon Reports predict that AR will soon see widespread use on US college campuses. In prepa­ration, this paper offers an overview of AR, examines recent AR developments, explores the impact of AR on society, and evaluates the implications of AR for learning and education.
Inducible Expression of a Constitutively Active Mutant of Mitogen-activated Protein Kinase Kinase 7 Specifically Activates c-JUN NH2-terminal Protein Kinase, Alters Expression of at Least Nine Genes, and Inhibits Cell Proliferation (2002)

MKK7 is a recently discovered mitogen-activated protein kinase (MAPK) kinase that is unique in that it specifically activates only the c-JUN NH(2)-terminal protein kinase (JNK) family of enzymes. Very little is known about the biological role of MKK7. We generated inducible cell lines from the human embryonal kidney carcinoma cell line, HEK293, by stable transfection with a constitutively active mutant of MKK7, MKK7(3E), fused to green fluorescent protein (GFP), under the control of an ecdysone-inducible promoter. Treatment of cells with the synthetic ecdysone analog ponasterone A induced expression of GFP-MKK7(3E) and resulted in sustained activation of endogenous JNK, but neither of the other endogenous MAPKs, ERK or p38. Red and green fluorescing cDNA copies of mRNA extracted from cells obtained before and after induction of GFP-MKK7(3E) were hybridized to microarrays containing more than 6,000 cDNAs in eight independent experiments. By selection criteria, 23 genes were differentially regulated after 24 h of induction of GFP-MKK7(3E) and 16 after 48 h. The expression of 9 genes was consistently changed after both 24 and 48 h of induction. These changes included down-regulation of three genes, c-myc, angiopoietin-2, and glucose-regulated protein 58, and up-regulation of 6 genes, tissue factor pathway inhibitor-2, GRP78, autotaxin, PPP1R7, the DKFZ cDNA p434D0818, and 1 unknown gene. Consistent with previously described roles of several of the altered genes, MKK7(3E) inhibited cell proliferation. These data implicate active MKK7 in the negative regulation of cell proliferation and provide evidence for a new role for this kinase in the regulation of a distinct, hitherto unrecognized set of genes.
Enhancing shale gas reservoir characterization using hydraulic fracture microseismic data (2012)

DECT multibearer channels (2002)

The DECT (Digital European Cordless Telecommunication) system has been designed to be used in three different environments: domestic, telepoint and business. For the business one voice and data services have to be offered allowing one to build a wireless network with integrated traffic. The DECT basic channel is symmetric and has a transmission rate of 32 kbps. This channel seems not very suitable for data applications so the DECT standard defines some procedures to handle data traffic in a better way. These procedures allows one to create connection oriented (symmetric or asymmetric) communications with a higher data transmission rate. These channels are created using multibearer connections.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Inhibition of Growth of<i>Clostridium botulinum</i>by Intestinal Microflora Isolated from Healthy Infants (1988)

Infant botulism results when Clostridium botulinum spores germinate, colonise, and produce botulinum neurotoxin in the intestine. As the normal intestinal microflora is important in resistance to C. botulinum colonisation in the mouse model of infant botulism, we investigated the effect of intestinal bacteria isolated from six healthy infants (two breastfed, two formula-fed, and two both formula and breast-fed) on the growth of 14 strains of C. botulinum (three Type A, four Type B, three Type E, two Type F, and two Type G) using zone inhibition procedures. We tested 88 anaerobic and 64 aerobic and facultative isolates. Strains of bifidobacteria, lactobacilli, propionibacteria and enterococci inhibited the growth of C. botulinum, as did several strains of the Bacteroides fragilis group. The only Clostridium inhibiting C. botulinum growth was C. ramosum, which inhibited both of the Type G strains and one of the two Type F strains. At least two bacterial isolates from each faecal sample inhibited most of the 14 C. botulinum strains. Co-culture experiments with intact faecal samples and C. botulinum spores or vegetative cells indicated that the normal flora of healthy infants had a bacteriostatic, rather than a bacteriocidal, effect on the growth of C. botulinum. Thus, susceptibility to infant botulism may result in part from the absence of these inhibitory organisms from the normal flora of the infant intestine.
A survey of iterative closest point algorithm (2017)

Registration of 3D point set is a very important problem in computer vision. As a widely used algorithm in 3D point set registration, the ICP algorithm has got much attention of researchers. This paper presents a comprehensive survey of the modified ICP algorithms in recent decade by five stages: selection of registration elements, feature metrics, search strategy, Weight of the Point Pair and the Solution of Rigid Transformation. Finally, this paper compared the standard ICP algorithm and the improved ICP algorithm's registration precision and convergence speed.
In Vitro Evaluation of Newly Developed Adsorbent for Selective Removal of Glycosylated Low‐Density Lipoprotein (2002)

Chronic hyperglycemia leads to the accumulation of nonenzymatically derived glycosylation products on proteins. Such glycosylation products, especially glycosylated low-density lipoprotein (glc-LDL), have been increasingly recognized as factors in the pathogeneses of diabetic complications. A new adsorbent was developed for the selective removal of glc-LDL from plasma. The adsorbent has dual ligands in order to improve the specific binding affinity for glc-LDL that consisted of boronic acid moiety for the glycosylated site and acrylic acid (AA) moiety for the apolipoprotein B of LDL. The adsorbent was synthesized by copolymerization of 4-vinyl phenyl boronic acid and AA. Five kinds of copolymers having different compositions were prepared and evaluated in terms of glc-LDL in vitro adsorption in human plasma. The adsorption behaviors were different depending on the polymer composition. The adsorbent having the AA composition from 50% to 90% showed very high selectivity for glc-LDL adsorption. The capability of selective adsorption was not impaired in human plasma. These results suggested that the adsorbent would be a promising material for glc-LDL apheresis.
