Hand-held Magnetoresistive Transducer (1974)

The initial design of a vertical magnetoresistive head in a hand-held wand for reading magnetically encoded price tags and credit cards is discussed. The performance of the head (e.g., resolution, signal shape and amplitude, and signal-to-noise ratio) is analytically and experimentally evaluated as a function of the configuration of the sensor, head-to-medium interface, and sensor processing and materials.
Long-term changes in adipose tissue in human disease (2001)

Redistribution of white adipose tissue is a long-term symptom of several chronic diseases. Although the roles of adipocytes in acute illness have been thoroughly studied, how or why short-term responses of adipose tissue to disease sometimes produce long-term redistribution, and the causal relationship between the anatomical changes and the associated metabolic syndromes are poorly understood. The present paper reviews explanations for the redistribution of adipose tissue after infection with HIV, and in Crohn's disease; both conditions that share the peculiarity of selective expansion of certain adipose depots while others are depleted. HIV adipose tissue redistribution syndrome (HARS) develops gradually after several months of infection with the HIV both in untreated patients and in those taking protease inhibitors and nucleoside reverse transcriptase inhibitors. Some current theories about the causes of HARS are critically assessed, and reasons presented for implicating local interactions between the immune system and perinodal adipocytes. Some evolutionary aspects of conspicuous long-term changes in the distribution of human adipose tissue are discussed. Adipose tissue acts as a social signal, indicating dietary history and previous exposure to pathogens. A distinctive symptom of Crohn's disease is selective enlargement of the mesenteric adipose tissue near the diseased lymph nodes and intestine. Perinodal adipocytes have site-specific properties not found in adipocytes from nodeless depots, such as perirenal and epididymal, that may equip them to interact locally with lymph-node lymphoid cells, making polyunsaturated fatty acids selectively and rapidly available to activated immune cells. Studies of the time course of activation of perinodal adipocytes via the lymph nodes they enclose indicate that prolonged or frequent stimulation recruits more adipocytes to control by immune cells, which may lead to selective enlargement of node-containing depots. These concepts suggest hypotheses about HARS and the anomalous development of mesenteric adipose tissue in Crohn's disease that could form the basis for further investigations.
CXCR2 Mediates the Recruitment of Endothelial Progenitor Cells During Allergic Airways Remodeling (2009)

Airway remodeling is a central feature of asthma and includes the formation of new peribronchial blood vessels, which is termed angiogenesis. In a number of disease models, bone marrow-derived endothelial progenitor cells (EPCs) have been shown to contribute to the angiogenic response. In this study we set out to determine whether EPCs were recruited into the lungs in a model of allergic airways disease and to identify the factors regulating EPC trafficking in this model. We observed a significant increase in the number of peribronchial blood vessels at day 24, during the acute inflammatory phase of the model. This angiogenic response was associated with an increase in the quantity of EPCs recoverable from the lung. These EPCs formed colonies after 21 days in culture and were shown to express CD31, von Willebrand factor, and vascular endothelial growth factor (VEGF) receptor 2, but were negative for CD45 and CD14. The influx in EPCs was associated with a significant increase in the proangiogenic factors VEGF-A and the CXCR2 ligands, CXCL1 and CXCL2. However, we show directly that, while the CXCL1 and CXCL2 chemokines can recruit EPCs into the lungs of allergen-sensitized mice, VEGF-A was ineffective in this respect. Further, the blockade of CXCR2 significantly reduced EPC numbers in the lungs after allergen exposure and led to a decrease in the numbers of peribronchial blood vessels after allergen challenge with no effect on inflammation. The data presented here provide in vivo evidence that CXCR2 is critical for both EPC recruitment and the angiogenic response in this model of allergic inflammation of the airways.
The Forgetron: A Kernel-Based Perceptron on a Budget (2008)

The Perceptron algorithm, despite its simplicity, often performs well in online classification tasks. The Perceptron becomes especially effective when it is used in conjunction with kernel functions. However, a common difficulty encountered when implementing kernel-based online algorithms is the amount of memory required to store the online hypothesis, which may grow unboundedly as the algorithm progresses. Moreover, the running time of each online round grows linearly with the amount of memory used to store the hypothesis. In this paper, we present the Forgetron family of kernel-based online classification algorithms, which overcome this problem by restricting themselves to a predefined memory budget. We obtain different members of this family by modifying the kernel-based Perceptron in various ways. We also prove a unified mistake bound for all of the Forgetron algorithms. To our knowledge, this is the first online kernel-based learning paradigm which, on one hand, maintains a strict limit on the amount of memory it uses and, on the other hand, entertains a relative mistake bound. We conclude with experiments using real datasets, which underscore the merits of our approach.
Providing VCR functionality in staggered video broadcasting (2002)

A true video-on-demand (TVoD) system allows users to view any video program, at any time, and perform any VCR function, but its per-user video delivery cost is very expensive. A near video-on-demand (NVoD) system uses a more scalable approach by batching multiple clients to a shared stream of broadcasting videos. Staggered video broadcasting, one of the NVoD techniques, broadcasts multiple streams of the same video at staggered times, with one stream serving multiple clients. In order to provide subscribers with a high-quality VoD service, it is desirable to add VCR functionality, such as fast forward and fast rewind, but it is not easy to provide VCR functionality in NVoD, especially a video broadcasting system where no dedicated or interactive channel is available. We analyze the conditions necessary to provide VCR functions and then propose a reception schedule that satisfies these conditions, with minimal resource requirements. Since our proposed scheme receives video frames as units, it can rapidly sustain a changing VCR action pattern. It is demonstrated, by simulation, that the scheme provides VCR functionality consistently with minimal buffer space.
Hydrothermal Synthesis of Er-Doped Luminescent TiO<sub>2</sub> Nanoparticles (2003)

Here we report the synthesis and characterization of a stable suspension of fluorescent erbium-doped titania nanoparticles and their assembly into thin films and photonic crystals. The nanoparticles were synthesized through a sol−gel process followed by peptization with tetramethylammonium hydroxide and hydrothermal treatment. As expected, following the hydrothermal treatment, X-ray diffraction shows the particles to be exclusively anatase. The nanoparticles form a stable suspension in water and were cast into 2- and 20-μm-thick films and formed into an inverse opal structure through templating with a colloidal crystal. As synthesized, only a faint fluorescence at 1532 nm was observed from the particles when pumped with 795-nm laser radiation; however, heat treatment at temperatures as low as 100 °C resulted in a significant increase in the fluorescence. The fluorescence was observed to increase further with annealing up to 500 °C, perhaps due to removal of hydroxyl groups and other surface species. Through energy-dispersive X-ray spectroscopy and X-ray diffraction, we present evidence that the Er ions are doped into the TiO2 nanoparticles and that Er was not present as free Er2O3. This work demonstrates the potential of rare-earth doping of titania nanoparticles for photonic applications.
베타 2-아드레날린 수용체의 유전자 변이형이 비만도에 미치는 영향 (2003)

Objectives: The lipolytic effects of catecholamines in adipose tissue are mediated by members of adrenergic receptors. This study was conducted to examine the effects of β2-AR Gln27Glu (Q27E) polymorphism on obesity indices and risk among obesity clinic patients. Methods: 532 subjects, 38 men and 494 women, who attended a weight loss program in a local obesity clinic were analyzed. Height, weight, BMI, WHR and obesity index were measured or calculated. Body composition was measured by bio-impedance analysis. Genotype of β2-AR polymorphism in codon 27 was analyzed by PCR-RFLP method. Serum concentrations of fasting glucose, total and HDL cholesterol, and triglyceride were determined by autobiochemical analyzer. Results: The Genotype distributions of β2-AR gene were QQ type 81.3%, QE type 17.9% and EE type 8%. Therefore, the frequency of E allele of β2-AR gene was 0.170 in the total subjects. The frequency of the β2-AR variant genotype(QE+EE) was significantly higher in obese group(BMI>25) compared with non-obese group(p=0.027). Weight was significantly higher in variant(QE+EE) type compared with normal(QQ) type in total subjects(p=0.001), male(p=0.022) and female(p=0.013). BMI, obesity index and WHR were also significantly higher in QE+EE type. Body fat mass was significantly higher in QE+EE type in total subjects(p=0.005) and female(p=0.027). When forward stepwise regression analysis was used to create a model of risk predictors of obesity(BMI>25), QE+EE type of β2-AR gene was found to be a significant risk factor for obesity (p=0.042, ORs 1.597). Conclusions: QE+EE genotype of β2-AR was associated with increased obesity indices and might be a significant risk factor for obesity.
Constitutive Modeling of Nanotube/Polymer Composites with Various Nanotube Orientations (2002)

In this study, a technique has been proposed for developing constitutive models for polymer composite systems reinforced with single-walled carbon nanotubes (SWNT) with various orientations with respect to the bulk material coordinates. A nanotube, the local polymer adjacent to the nanotube, and the nanotube/polymer interface have been modeled as an equivalent-continuum fiber by using an equivalent-continuum modeling method. The equivalent-continuum fiber accounts for the local molecular structure and bonding information and serves as a means for incorporating micromechanical analyses for the prediction of bulk mechanical properties of SWNT/polymer composite. As an example, the proposed approach is used for the constitutive modeling of a SWNT/LaRC-SI (with a PmPV interface) composite system, with aligned nanotubes, three-dimensionally randomly oriented nanotubes, and nanotubes oriented with varying degrees of axisymmetry. It is shown that the Young s modulus is highly dependent on the SWNT orientation distribution.
Robust Bi-Tempered Logistic Loss Based on Bregman Divergences (2019)

We introduce a temperature into the exponential function and replace the softmax output layer of neural nets by a high temperature generalization. Similarly, the logarithm in the log loss we use for training is replaced by a low temperature logarithm. By tuning the two temperatures we create loss functions that are non-convex already in the single layer case. When replacing the last layer of the neural nets by our bi-temperature generalization of logistic loss, the training becomes more robust to noise. We visualize the effect of tuning the two temperatures in a simple setting and show the efficacy of our method on large data sets. Our methodology is based on Bregman divergences and is superior to a related two-temperature method using the Tsallis divergence.
A new variable stiffness actuator (CompAct-VSA): Design and modelling (2011)

This paper describes the design and modelling of a new variable stiffness actuator (CompAct-VSA). The principle of operation of CompAct-VSA is based on a lever arm mechanism with a continuously regulated pivot point. The proposed concept allows for the development of an actuation unit with a wide range of stiffness and a fast stiffness regulation response. The implementation of the actuator makes use of a cam shaped lever arm with a variable pivot axis actuated by a rack and pinion transmission system. This realization results in a highly integrated and modular assembly. Size and weight are indeed an open issue in the VSAs design, which ultimately limit their implementation in multi-dof robotic systems. The paper introduces the mechanics, the principle of operation and the model of the actuator. Preliminary results are presented to demonstrate the fast stiffness regulation response and the wide range of stiffness achieved by the proposed CompAct-VSA design.
Temperature and doping dependence of non-Gaussian<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mn>1</mml:mn><mml:mo>/</mml:mo><mml:mi>f</mml:mi></mml:math>noise and noise statistics in hydrogenated amorphous silicon (1997)

Coplanar conductance fluctuations in hydrogenated amorphous silicon have been measured as a function of doping type and temperature and are found to have an inverse frequency $(1/f)$ spectral density. The $1/f$ noise statistics are non-Gaussian as reflected by (i) strong correlations of the noise power across frequency space and (ii) a power-law second spectrum. The $1/f$ noise and $1/f$ noise statistics exhibit weak doping and temperature dependences. The results are discussed in terms of a model for electronic conduction involving inhomogeneous current filaments whose conductance is modulated by hydrogen diffusion. The growth of the frequency correlation coefficients with averaging time, the variation of the magnitudes of the correlation coefficients with the magnitudes of the second spectrum, and the scaling properties of the second spectra are consistent with the presence of hierarchical kinetics.
Time-domain spectroscopy of dielectric materials (1976)

The uses are discussed of formulas derived by input admittance analysis for the complex permittivity of dielectric samples, placed in a matched coaxial line or terminating it, as a function of the Fourier transforms of the incident and reflected real time pulses observed in time-domain spectroscopy. Precautions to be taken for dielectrics with appreciable ohmic conductance are described, and it is also shown that magnetic permeabilities of linear isotropie materials can be obtained by measurements of open- and short-circuited samples.
Effects of substrate treatment on the initial growth mode of indium-tin-oxide films (2004)

The initial growth mode of indium tin oxide (ITO) on polycarbonate (PC) substrates was investigated. Some of the PC substrates were bombarded by 1-keV Ar ions in an oxygen environment to modify the substrate surface before ITO sputter deposition. The initial part of the film growth was transformed from a three-dimensional island growth to a two-dimensional like growth as a result of the surface treatment. The change of the growth mode was attributed to oxygen-bound functional groups newly formed on the PC surface. Models based on thermodynamic theory and on atomic kinetic approach are presented to explain the transition, respectively.
Perspectives on Systematic Analyses of Gene Function in Arabidopsis thaliana: New Tools, Topics and Trends (2011)

Since the sequencing of the nuclear genome of Arabidopsis thaliana ten years ago, various large-scale analyses of gene function have been performed in this model species. In particular, the availability of collections of lines harbouring random T-DNA or transposon insertions, which include mutants for almost all of the ~27,000 A. thaliana genes, has been crucial for the success of forward and reverse genetic approaches. In the foreseeable future, genome-wide phenotypic data from mutant analyses will become available for Arabidopsis, and will stimulate a flood of novel in-depth gene-function analyses. In this review, we consider the present status of resources and concepts for systematic studies of gene function in A. thaliana. Current perspectives on the utility of loss-of-function and gain-of-function mutants will be discussed in light of the genetic and functional redundancy of many A. thaliana genes.
A Compression Framework for Personal Image Used in Mobile RFID System (2008)

Radio frequency identification (RFID), a novel automatic identification technology, has been widely used in modern society. To improve the security of RFID card, a novel idea of inserting personal image to the card and restoring it rapidly on the mobile device is proposed in this paper. A compression framework based on facial feature is proposed to solve the key problem caused by memory limitation of RFID card and resource limitations of the mobile system. In this framework, the facial region is detected and extracted at first, and then compressed with high compression ratio using fast lifting wavelet transform. After that, the compressed data is encoded and saved in the card. Experimental results indicate that higher compression ratio, better image quality and rapid decompression can be achieved by using this framework.
Treatment of pulmonary exacerbations of cystic fibrosis leads to improved antioxidant status (1999)

Many cystic fibrosis (CF) patients have increased circulating levels of oxidation products and/or decreased antioxidant status. This study investigated whether treatment of pulmonary exacerbations decreased oxidative stress in CF patients. Seventeen adult patients were studied at the beginning and end of treatment with intravenous antibiotics. Plasma concentrations of the antioxidants ascorbic acid, alpha-tocopherol, uric acid and total reduced thiols, together with plasma retinol, lipid hydroperoxides, malondialdehyde and protein carbonyl levels were determined. Median (interquartile range) pretreatment and post-treatment levels were compared using the Wilcoxon signed rank test. Clinical resolution was reflected by improved spirometry. Significant increases were observed in plasma ascorbic acid (pre 30.4 (15.7-38.6) microM, post 35.2 (27.3-49.6) microM), alpha-tocopherol (pre 19.7 (13.6-25.2) microM, post 25.2 (19.3-31.6) microM) and retinol (pre 1.9 (1.5-2.5) microM, post 2.7 (1.7-3.5) microM). No change in plasma total reduced thiols occurred following treatment (pre 409 (366-420) microM, post 392 (366-423) microM), whereas uric acid fell with treatment (pre 307 (274-394) microM, post 260 (216-317) microM). Neither plasma protein carbonyls or malondialdehyde levels altered with treatment (protein carbonyls pre 0.47 (0.28-1.27), post 0.67 (0.42-0.83) nM x mg protein(-1); malondialdehyde pre 0.75 (0.53-1.18), post 0.84 (0.65-1.15) microM). Lipid hydroperoxides levels did decrease following treatment (53 (18-85) versus 17 (10-55) nM). This study demonstrated that treatment of infective exacerbations resulted in increased plasma levels of some antioxidant vitamins. No immediate change in plasma protein oxidation was observed, but lipid oxidation was decreased.
Monitoring Container Services at the Network Edge (2017)

Recent developments induced by the Internet of Things (IoT) force a paradigm shift to deploy on demand services to a broad range of different computing architectures. Mainly single board computers (SBCs) gained a lot of attraction in recent years, shifting highly available processing power to service consumers and IoT devices. Simultaneously, container virtualization achieved a breakthrough by the well known Docker environment that became a key competitor to the utilization of virtual machines. Nevertheless, spreading containers at small scale needs a proper allocation of resources available on SBCs.,, As a first step, we developed a multi-architecture framework "PyMon" to monitor different computing architectures with a small footprint. PyMon itself is based on the recent version of "monit" and a "Django" application to collect monitoring data. It is delivered by several Docker images and allows monitoring with a reasonable processing overhead. Our demonstration shows the statistics of either processes or containers running on a cluster of SBCs, where each member is monitored. Furthermore, we evaluated the resource usage of the two key competitors for container cluster management on SBCs, Kubernetes and Docker Swarm, with PyMon.
A new access protocol for uni-directional twin-bus architectures (2003)

The authors propose basic access protocols for a twin-bus unidirectional bus system (UBS) implementation. The proposed protocols are fairly similar to that of Fasnet. However, the gaps between cycles have been considerably reduced. The savings will particularly increase with cable bandwidth. In fact, except for a few cases of light load traffic the proposed protocol achieves close to 100% channel utilization.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Simulation Study of A Low-Low Satellite-to-Satellite Tracking Mission (2000)

The Gravity Recovery and Climate Experiment (GRACE) is a dedicated spaceborne mission to map the Earth’s gravity field with unprecedented accuracy. The GRACE mission is planned to launch in 2001, for a lifetime of approximately 5 years. It consists of two satellites, co-orbiting in nearly polar orbit, at approximately 300-500 km altitude, separated by 100-500 km along track. Primary measurements are the range change between the two satellites, which represents the gravity perturbation differences between the two locations. These range changes are measured by a high accuracy microwave raging system. To detect the non-gravitational perturbations, which also affect the range change, three axis accelerometers are used. In this study, full numerical simulations were performed to evaluate the gravity recovery accuracy, and to determine sensitivity of gravity estimation to mission and design parameters. The measurement and dynamic model equations were derived and presented along with the description of the simulation procedure. The error models on two major instruments, the inter-satellite ranging system and accelerometer, were described and their effect on the estimation accuracy were discussed. Series of extensive simulations were performed to analyze the impact of the various simulation parameters, which included the orbit parameters, measurement types, and so on. Comprehensive error models made it possible to perform realistic analyses. To the extent that the error sources assumed in the simulations represent those actually encountered during the mission, the simulation results will predict the performance of the GRACE mission. The GRACE mission is expected to improve the current knowledge of the Earth gravity field by order of magnitude. The geoid error level is expected to be less than 1cm to spherical harmonic degree 70.
