Adaptive QoS for mobile multimedia applications using power control and smart antennas (2000)

There has been an increase in demand for multimedia services in wireless communication networks. The increase in data transmission required for multimedia places considerable strain on the limited resources that have traditionally served users with only speech requirements. We address the problem of providing the individual quality of service (QoS) needs of each user, according to the different multimedia service type, be it voice, video, image or data. We propose a scheme to improve the signal to interference noise ratio (SINR) for those users with multimedia services by exploiting power control and smart antennas, while not affecting users with voice service. We also propose a scheme for fast activation of new users into such a network.
Oxidative Stress, Endothelial Dysfunction and Atherosclerosis (2009)

This review focuses on the role of oxidative processes in atherosclerosis and the cardiovascular diseases (CVD) that can arise as a result. Atherosclerosis represents a state of heightened oxidative stress characterized by lipid and protein oxidation in the vascular wall. Overproduction of reactive oxygen species (ROS) under pathophysiologic conditions forms an integral part of the development of CVD, and in particular atherosclerosis. Endothelial dysfunction, characterized by a loss of nitric oxide (NO) bioactivity, occurs early on in the development of atherosclerosis, and determines future vascular complications. Although the molecular mechanisms responsible for mitochondria-mediated disease processes are not clear, oxidative stress seems to play an important role. In general, ROS are essential to the functions of cells, but adequate levels of antioxidant defenses are required in order to avoid the harmful effects of excessive ROS production. In this review, we will provide a summary of the cellular metabolism of reactive oxygen species (ROS) and its role in pathophysiological processes such as atherosclerosis; and currently available antioxidants and possible reasons for their efficacy and inefficacy in ameliorating oxidative stress-mediated diseases.

Limiting recursion (1965)

A class of problems is called decidable if there is an algorithm which will give the answer to any problem of the class after a finite length of time. The purpose of this paper is to discuss the classes of problems that can be solved by infinitely long decision procedures in the following sense: An algorithm is given which, for any problem of the class, generates an infinitely long sequence of guesses. The problem will be said to be solved in the limit if, after some finite point in the sequence, all the guesses are correct and the same (in case there is more than one correct answer). Functions, sets, and functionals which are decidable by such infinite algorithms will be called limiting recursive . These, together with classes of objects which can be identified in the limit , are the subjects of this report. Without qualification, set will mean set of numbers; function will mean number-theoretic function of 1 variable, possibly partial; functionals will take numerical values and have any number of numerical and/or function variables, the latter ranging solely over total functions of 1 variable. Thus a function is a special case of a functional, x will invariably stand for a numerical variable; φ for a function variable; g for a guess (a number); n for the numerical variable which indexes the guesses, referred to as the time .
Towards geo-spatial hypermedia: Concepts and prototype implementation (2002)

This paper combines spatial hypermedia with techniques from Geographical Information Systems and location based services. We describe the Topos 3D Spatial Hypermedia system and how it has been developed to support geo-spatial hypermedia coupling hypermedia information to model representations of real world buildings and landscapes. The prototype experiments are primarily aimed at supporting architects and landscape architects in their work on site. Here it is useful to be able to superimpose and add different layers of information to, e.g. a landscape depending on the task being worked on. We introduce a number of central concepts to understand the relation between hypermedia and spatial information management. The distinction between metaphorical (and abstract) versus literal (and concrete) spaces is introduced together with a workspace composition semantics and a distinction between direct and indirect navigation. Finally, we conclude with a number of research issues which are central to the future development of geo-spatial hypermedia, including design issues in combining metaphorical and literal hypermedia space, as well as a discussion of the role of spatial parsing in a geo-spatial context.
A Semi-Cylindrical Capacitive Sensor Used For Soil Moisture Measurement (2013)

Differing from the structure of traditional parallel plate capacitive sensor a semi cylindrical capacitive sensor has been introduced in this present work to measure the soil moisture conveniently. Here, the numerical analysis method to evaluate the capacitance from the semi-cylindrical capacitive sensor is analyzed and discussed. The changes of capacitance with the variation of soil moisture obtained linear in the nano farad range (nF) and which converted into voltage variation by using proper signal conditioning circuit. Experimental results depict the satisfactory performance of the sensor for measurement of soil moisture in the range of 0 to 70%. We investigated the linearity of 4% of FSO and sensitivity of 70 mV/unit percentage changes in soil moisture level (DB).
Introgression of a major QTL from an inferior into a superior population using genomic selection (2009)

Substantial differences between introgression programs using classical and genomic selection were observed, and the former was generally inferior with respect to both genetic gain and the ability to preserve the target QTL. Combining genomic selection with gene-assisted selection for the target QTL acted as an extra precaution against loss of the target QTL and gave additional genetic gain for disease resistance. However, the effect on total merit index was limited.
Identification and Assessment of Antioxidant Capacity of Phytochemicals from Kiwi Fruits (2009)

The kiwi fruit is the edible berry of a cultivar group of the woody vine of several Actinidia species. The most common commercially available, green-fleshed kiwi fruit is the cultivar 'Hayward', which belongs to the Actinidia deliciosa species. An antioxidative screening of kiwi fruit components (peel and pulp) crude extracts was carried out using specific assay media characterized for the presence of highly reactive species such as 2,2'-diphenyl-1-picrylhydrazyl radical (DPPH(•)), H(2)O(2), and O(2)(•-). The Mo(VI) reducing power of the samples was also determined. The phenol and flavonoid contents were quantified. Phytochemical analysis of kiwi peel crude extracts led to the isolation of vitamin E, 2,8-dimethyl-2-(4,8,12-trimethyltridec-11-enyl)chroman-6-ol, as well as α- and δ-tocopherol, 7 sterols, the triterpene ursolic acid, chlorogenic acid, and 11 flavonoids. Chemical fractionation of pulp crude extracts led to the isolation of two caffeic acid glucosyl derivatives and two coumarin glucosydes, besides the three vitamin E, β-sitosterol, stigmasterol, and its Δ(7) isomer, campesterol, chlorogenic acid, and some flavone and flavanol molecules. All of the compounds were tested for their radical scavenging and antioxidant capabilities by measuring their capacity to scavenge DPPH and anion superoxide radical and to reduce a Mo(VI) salt.
"Matrix effects" in immunoassays. (1991)

This article deals with "matrix effects" in immunoassay systems. As each component has its own matrix (buffer, antibody, separation agents), the term matrix effect--usually only referring to the matrix of the sample--has been replaced by the term interference effect. The possible sites of interference have been dealt with in turn, taking each component/step of an immunoassay separately. Results of assay improvement due to the removal of "matrix effects" are given using the PTH-assay as example. The change in results due to tampering with the serum matrix is given using the determination of free thyroxine in commercial quality control sera.
Error concealment with directional filtering for block transform coding (2002)

In the paper, an error concealment algorithm using directional filtering for block-based coding is presented. Block transform coding is very powerful for image or video compression. Algorithms based on one of the most famous block transform coding methods, the discrete cosine transform, can provide good quality reconstructed video with higher than 20:1 compression ratio. As new applications arise, the problems of imperfect channels need to be considered. The problem addressed in the paper is the concealment of damaged regions in video images using the correlated information in the received signals. Spatial interpolation is an important approach to error concealment, especially in stressful image sequences where motion cannot be accurately predicted or in intra-coded frames which have no motion information. The authors propose a new approach which utilizes spatially correlated information thoroughly by performing interpolation based on a large local neighborhood of surrounding pixels. The use of directional information results in the recovery of edges, which have great influence in the perceived subjective quality of images. Computer simulation results have shown notable improvement over existing algorithms. If the damaged block is surrounded by validly decoded blocks, the edge recovery in the lost blocks is very successful.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Extended constant-torque and constant-power speed range control of permanent magnet machine using a current source inverter (2009)

High-performance interior permanent magnet (IPM) machine drives using a current source inverter (CSI) are being studied for hybrid electric vehicle applications. This paper focuses on extending the constant-torque and constant-power operation ranges of an IPM machine by utilizing the voltage-boosting capability of the CSI. An equivalent circuit model of the IPM machine, including the inverter AC filter capacitors and the motor core-loss resistor, is presented and used to ensure the tracking of the torque-producing current of the PM machine to the commanded value under all operating conditions. A novel control strategy is proposed to achieve both minimum system losses and high system performance over the entire operating range, including the field-weakening region. Simulation and experimental results are presented to validate the functionality of the boost mechanism, the effectiveness of the equivalent circuit model, and the proposed control scheme.
A stochastic architecture for neural nets (1988)

A stochastic digital architecture is described for simulating the operation of Hopfield neural networks. This architecture provides reprogrammability (since synaptic weights are stored in digital shift registers), large dynamic range (by using either fixed or floating-point weights), annealing (by coupling variable neuron gains with noise from stochastic arithmetic), high execution speeds ( approximately=N*10/sup 8/ connections per second), expandability (by cascading of multiple chips to host large networks), and practicality (by building with very conservative MOS device technologies).< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

A Generic Battery Model for the Dynamic Simulation of Hybrid Electric Vehicles (2007)

This paper presents an easy-to-use battery model applied to dynamic simulation software. The simulation model uses only the battery State-Of-Charge (SOC) as a state variable in order to avoid the algebraic loop problem. It is shown that this model, composed of a controlled voltage source in series with a resistance, can accurately represent four types of battery chemistries. The model's parameters can easily be extracted from the manufacturer's discharge curve, which allows for an easy use of the model. A method is described to extract the model's parameters and to approximate the internal resistance. The model is validated by superimposing the results with the manufacturer's discharge curves. Finally, the battery model is included in the SimPowerSystems (SPS) simulation software and is used in the Hybrid Electric Vehicle (HEV) demo. The results for the battery and for the DC-DC converter are analysed and they show that the model can accurately represent the general behaviour of the battery.

Dual-band VCO using composite right/left-handed transmission line and tunable negative resistance based on pin diode (2008)

In this paper, the dual-band voltage-controlled oscillator (VCO) using the composite right/left-handed (CRLH) transmission line (TL) and the tunable negative resistance based on the pin diode is presented. It is demonstrated that the CRLH TL can lead to metamaterial transmission line with the dual-band tuning. The dual-band of the CRLH TL is achieved by the frequency offset and the phase slope of the CRLH TL. The tunable negative resistance based on the pin diode has been used to operate the dual-band of VCO. The phase noise of VCO is −108.34 ∼ −106.67 dBc/Hz @ 100 kHz in the tuning range, 2.423 ∼ 2.597 GHz for the forward bias of the pin diode, whereas that of VCO is −114.16 ∼ −113.33 dBc/Hz @ 100 kHz in the tuning range, 5.137 ∼ 5.354 GHz for the reverse bias of the pin diode.
Effects of vasoactive intestinal peptide on adenosine 3',5'- monophosphate, ornithine decarboxylase, and cell growth in a human colon cell line (1992)

Vasoactive intestinal peptide (VIP) is a widely distributed neuropeptide that has been considered a potential regulator of cell growth and differentiation in various tissues, including the gut. To examine this idea, we used a human colon carcinoma cell line (LoVo) as a model system and measured ornithine decarboxylase (ODC), because this is the rate-limiting enzyme for the formation of polyamines, which are thought to be key factors in regulating cell growth. LoVo cells, grown to about 80% confluence in F-12 medium containing 10% fetal bovine serum, were preincubated for 5 h in low serum medium (1% fetal bovine serum in F-12), and ODC activity was determined by measuring 14CO2 liberated from 14C-labeled ornithine. VIP caused a dose-related biphasic change in ODC, with activity increased at 10 pM, maximal (5-fold increase) at 10 nM, and decreased toward basal at 100 nM to 1 microM. Incubation of cells for 6 days with VIP in low serum medium showed similar changes in cell numbers, with growth being increased by doses in the 1 pM to 100 nM range and decreased at higher doses (greater than or equal to 100 nM). Exposure of cells to 5 mM alpha-difluoromethylornithine blocked both the VIP-induced increase in cell number and the VIP-induced increase in ODC activity. Increased ODC mRNA was detected after 2 h of exposure to VIP, a time at which ODC activity peaked after treatment, and the increase in ODC mRNA caused by VIP was dose-dependent. In related experiments LoVo cells were found to have high affinity VIP receptors (Kd = 0.4 nM), as assessed by examination of [125I]VIP binding in the presence of varying concentrations of unlabeled VIP. Studies of intracellular cAMP revealed a dose-related increase in cAMP in response to VIP (ED50 = 11 pM), and the adenylate cyclase activator forskolin increased both ODC activity and ODC mRNA. The findings support the idea that LoVo cells have VIP receptors linked to cAMP which can stimulate cell growth at least in part by increasing ODC synthesis and activity, thereby altering the production of polyamines. The decreased growth and ODC activity observed with high doses of VIP may involve a second messenger other than cAMP.
Ectoenzymes of the kidney microvillar membrane. Affinity purification, characterization and localization of the phospholipase C-solubilized form of renal dipeptidase (1989)

Renal dipeptidase (EC 3.4.13.11) was solubilized from pig kidney microvillar membranes with bacterial phosphatidylinositol-specific phospholipase C and then purified by affinity chromatography on cilastatin-Sepharose. The enzyme was apparently homogeneous on SDS/polyacrylamide-gel electrophoresis with an Mr of 47,000. Immunohistochemical analysis of the distribution of the dipeptidase showed it to be concentrated in the brush-border region of the proximal tubules in close association with endopeptidase-24.11) (EC 3.4.24.11). The purified dipeptidase was shown to contain 1 mol of inositol/mol and to possess the cross-reacting determinant characteristic of the glycosyl-phosphatidylinositol membrane-anchoring domain. The glycoprotein nature of renal dipeptidase was confirmed by chemical and enzymic deglycosylation. These results establish renal dipeptidase as a glycosyl-phosphatidylinositol-anchored ectoenzyme of the microvillar membrane.

Bioactive peptides in dairy products (2009)

Bioactive peptides are specific protein fragments that have a positive impact on body functions and conditions and may ultimately influence health. Most of the biological activities are encrypted within the primary sequence of the native protein and can be released by enzymatic hydrolysis and proteolysis or by food processing. Milk is a rich source of bioactive peptides which may contribute to regulate the nervous, gastrointestinal and cardiovascular systems as well as the immune system, confirming the added value of dairy products that, in certain cases, can be considered functional foods. The main biological activities of these peptides and their bioavailability in dairy products are reviewed. The natural concentration of these biomolecules is quite low and, to date one of the main goals has been to realize products enriched with bioactive peptides that have beneficial effects on human health and proven safety. Even though several health-enhancing products have already been launched and their integration in the diet could help in the prevention of chronic diseases such as hypertension, cancer and osteoporosis, more clinical trials are required in order to develop a deeper understanding of the activity of biopeptides on the human physiological mechanisms and also to assess the efficacy of their effects in a long term view. New scientific data are also needed to support their commercialisation in compliance with current regulations.
Quantitative desorption analysis of ultra large scale integration materials by thermal desorption spectroscopy. (1994)

四重極質量分析計を用いた昇温脱離ガス分析法により半導体集積回路材料からの脱離無機ガスの定量分析法について検討した.既知量の水素をイオン注入したSiウェハーを用いて,昇温脱離スペクトルのピーク面積から測定再現性,定量性について評価した.繰り返し測定の再現性は,水素分子の脱離量(5×1014H2/cm2)に対し相対標準偏差で5%内に入ることを確認した.その脱離量はイオン注入ドーズ量に比例し信頼性の高い検量線が作成でき,フッ化水素酸水溶液で処理したSi(001)表面のダングリングボンドはほとんどすべて水素終端されていることを水素分子の脱離量から検証した.又,水素に対する検量線と四重極質量分析計のフラグメンテーションファクターやイオン化難易度を考慮することにより,他の無機ガスに対しても脱離ガスの定量分析が可能であることを半導体集積回路材料からの水の脱離量により検証した.本方法が半導体集積回路材料からの放出ガスの定量分析に有効であることを示すとともに,従来,微量定量分析が困難であった水素や水に対しても,脱離量の検出下限は約1×1013/cm2と高感度な定量分析が可能であることを明らかにした.
