Cognitive Radio: Methods for the Detection of Free Bands (2009)

In contrast to current systems where the spectrum allocation is static, future cognitive radio devices will be able to seek and use in a dynamic way the frequencies for network access; this will be done by autonomous detection of vacant bands in the radio spectrum. Many of the cognitive systems use highly complex algorithms for enabling dynamic spectrum access. With a variety of hardware systems available to run these algorithms, it is becoming necessary to have a common interface to the software defined radio. In order to meet the growing demands for interoperability, this article proposes a workflow for developing new software defined radio platforms. In this article, we are interested in various methods of detection of a signal embedded in the noise by specifying their advantages and their drawbacks.

Here we reveal maps of bodily sensations associated with different emotions using a unique topographical self-report method. In ...
Mobile health use in low- and high-income countries: an overview of the peer-reviewed literature (2013)

The evolution of mobile phone technology has introduced new possibilities to the field of medicine. Combining technological advances with medical expertise has led to the use of mobile phones in all healthcare areas including diagnostics, telemedicine, research, reference libraries and interventions. This article provides an overview of the peer-reviewed literature, published between 1 August 2006 and 1 August 2011, for the application of mobile/cell phones (from basic text-messaging systems to smartphones) in healthcare in both resource-poor and high-income countries. Smartphone use is paving the way in high-income countries, while basic text-messaging systems of standard mobile phones are proving to be of value in low- and middle-income countries. Ranging from infection outbreak reporting, anti-HIV therapy adherence to gait analysis, resuscitation training and radiological imaging, the current uses and future possibilities of mobile phone technology in healthcare are endless. Multiple mobile phone based applications are available for healthcare workers and healthcare consumers; however, the absolute majority lack an evidence base. Therefore, more rigorous research is required to ensure that healthcare is not flooded with non-evidence based applications and is maximized for patient benefit.
Remote detection of coral 'bleaching' using pulsed-laser fluorescence spectroscopy (1992)

Despite their biological and economic importance coral reefs are increasingly threatened by human activities. Recently, 'bleaching' of reefs, i.e. loss of photosynthetic pigmentation, has occurred at numerous globally-distributed sites. A number of environmental stressors, including increased water temperature, can induce bleaching. Several investigators have suggested that the widespread occurrence of coral bleaching represents an early warning signal of global greenhouse warming. Regardless of the cause, the extent of coral bleaching, both regionally and globally, needs to be documented and monitored. We conducted laboratory studies to evaluate the potential of using remotely-sensed laser-induced fluorescence to monitor coral pigmentation. Five species of Caribbean corals were collected, transported to the laboratory, and maintained in aquaria. Coral samples were irradiated at either 532 nm or 337 nm with pulsed-laser light and spectral scans of fluorescence were collected at 1 nm intervals. Dlstinct chlorophyll fluorescence peaks at 685 and 740 nm were observed in all species examined. In corals exposed to temperature-induced stress, incipient changes In the fluorescence spectra could be detected prior to visible bleaching and coral death. Remotely-measured (aircraft or ship) laser-induced fluorescence provides a potentially useful tool for monitoring the pigmentation status of coral reefs. Field validation will be necessary, but our results suggest that it may be possible to distinguish bleaching, or even partial bleaching, over large geographical areas with sensitivity and rapidity.

<i>Borrelia</i> species induce inflammasome activation and IL‐17 production through a caspase‐1‐dependent mechanism (2010)

Borrelia burgdorferi spirochetes cause Lyme disease, which can result in severe clinical symptoms such as multiple joint inflammation and neurological disorders. IFN-γ and IL-17 have been suggested to play an important role in the host defense against Borrelia, and in the immunopathology of Lyme disease. The caspase-1-dependent cytokine IL-1β has been linked to the generation of IL-17-producing T cells, whereas caspase-1-mediated IL-18 is crucial for IFN-γ production. In this study, we show by using knockout mice the role of inflammasome-activated caspase-1 in the regulation of cytokine responses by B. burgdorferi. Caspase-1-deficient cells showed significantly less IFN-γ and IL-17 production after Borrelia stimulation. A lack of IL-1β was responsible for the defective IL-17 production, whereas IL-18 was crucial for the IFN-γ production. Caspase-1-dependent IL-33 played no role in the Borrelia-induced production of IL-1β, IFN-γ or IL-17. In conclusion, we describe for the first time the role of the inflammasome-dependent caspase-1 activation of cytokines in the regulation of IL-17 production induced by Borrelia spp. As IL-17 has been implicated in the pathogenesis of chronic Lyme disease, these data suggest that caspase-1 targeting may represent a new immunomodulatory strategy for the treatment of complications of late stage Lyme disease.

Differential expression of Toll-like receptor 2 in human cells (2001)

Human Toll-like receptor 2 (TLR2) is a receptor for a variety of microbial products and mediates activation signals in cells of the innate immune system. We have investigated expression and regulation of the TLR2 protein in human blood cells and tissues by using two anti-TLR2 mAbs. Only myelomonocytic cell lines expressed surface TLR2. In tonsils, lymph nodes, and appendices, activated B-cells in germinal centers expressed TLR2. In human blood, CD14+ monocytes expressed the highest level of TLR2 followed by CD15+ granulocytes, and CD19+ B-cells, CD3+ T-cells, and CD56+ NK cells did not express TLR2. The level of TLR2 on monocytes was after 20 h up-regulated by LPS, GM-CSF, IL-1, and IL-10 and down-regulated by IL-4, IFN-gamma, and TNF. On purified granulocytes, LPS, GM-CSF, and TNF down-regulated, and IL-10 modestly increased TLR2 expression after 2 h. These data suggest that TLR2 protein expression in innate immune cells is differentially regulated by inflammatory mediators.
METACHROMATIC BASOPHILIA OF KERATIN AFTER OXIDATION-CLEAVAGE OF DISULFIDE BONDS (1954)

Oxidation of keratinous structures by peracetic acid, bromine in carbon tetrachloride, or neutral potassium permanganate produced an insoluble, strongly acid substance capable of taking up basic dyes even from pH 1.2 solution. Thus, hair shafts, nails, and, to a much less extent, stratum corneum of the epidermis were rendered basophilic and metachromatic. The oxidation product strongly resisted methylation, thereby differing from the basophil substance of cell nuclei, of mast cell granules, and of cartilage. Furthermore, the oxidation product was not blocked by aniline chloride or phenylhydrazine, indicating that aldehydes, if formed, were not responsible for the basophilia by the formation of Schiff's bases. Periodic acid (1% aqueous solution for 2 hours at 60°C.) also rendered keratinous structures basophilic but to a less intensity than with the other oxidizing agents. Chromic acid was ineffective under the conditions used and, moreover, largely destroyed nuclear basophilia. The various oxidizing agents that induced metachromatic basophilia in keratin have in common the property of cleaving the disulfide bonds of cystine, yielding cysteic acid. In the case of oxidized keratin, it appears that the resultant cysteic acid residues remain bound in peptide chains but still possess free sulfonic acid radicals. Since sulfonic acids are strong acids, such groups probably account for the observed metachromatic basophilia in oxidized keratinous structures.
The photoaffinity probe 8-azidoadenosine 5'-triphosphate selectively labels the heavy chain of Chlamydomonas 12 S dynein. (1984)

Chlamydomonas 12 S dynein, which makes up part of the outer arm of the flagellar axoneme, consists of three polypeptides of 330,000, 22,000, and 18,000 daltons. We have used 8-azidoadenosine 5'-triphosphate (8-N3ATP), a photoaffinity analog of ATP, to investigate which of the dynein polypeptides contains the site of ATP hydrolysis. 8-N3ATP is a competitive inhibitor of the hydrolysis of ATP by 12 S dynein and is hydrolyzed by 12 S dynein in an ATP- and vanadate-sensitive fashion, indicating that it binds to the 12 S dynein hydrolytic site in the same way as ATP. When dynein was incubated with [gamma-32P]- or [alpha-32P]8-N3ATP in the presence of UV light to activate the azido moiety, the analog was incorporated into 12 S dynein's heavy polypeptide chain, but not its light chains. The incorporation was UV-dependent, was blocked by addition of ATP or vanadate plus ADP to the reaction mixture, and did not occur in heat-denatured dynein. These results strongly suggest that the hydrolytic site of 12 S dynein is contained in its heavy chain.
Grain Refinement and Texture Formation during High‐Strain Torsion of NiAl (2004)

The intermetallic compound NiAl has special properties, like high melting point, low density, good corrosion resistance and moderate creep strength, making this material interesting for high-temperature applications. However, a widespread acceptance as structural material was hindered so far by the inadequate low-temperature toughness and ductility. Attempts to increase the ductility of NiAl by alloying have not been successful [1]. Another way to approach this problem is by changing the grain structure and texture on purpose. As the yield stress increases much slower with decreasing grain size than the fracture stress, grain refinement should help to reach the ductile field (Fig. 1) [2]. This field can be extended by changing the texture in such a way that the Taylor factor is reduced. Thus, in order to optimize the desired mechanical properties by thermomechanical treatment it is of particular interest to understand the mechanism of grain structure and texture formation during deformation and annealing. Therefore, it was the aim of the present work to strongly deform NiAl polycrystals in torsion, a deformation mode allowing the study of microstructure and texture with strain. To do this, methods with high spatial resolution had to be used which are given by electron back-scatter diffraction (EBSD) in the scanning electron microscope (SEM) and by texture measurements with high-energy synchrotron radiation.
PO131 DIDO Timing For a Secondary Care Hospital, How to Improve Them? A Suadi Experience (2018)

A shallow CO2 injection experiment was conducted in an unconfined, unconsolidated siliclastic aquifer in western Denmark. The aims were to test injection and sampling systems, confirm the conceptual hydrogeological site model and determine the aquifers potential geochemical response to a larger scale, sustained CO2 injection in order to finalize design of the main release experiment. Food grade CO2 (45 kg in 48 h) was injected at 10 m depth into glacial sand and water chemistry subsequently monitored. Results indicate the injection system effectively delivered CO2 gas into the glacial sand layer where it dissolved and moved with advective flow. Dissolved CO2 was not detected in the aeolian sand (0–5 m depth) indicating prevention of migration due to permeability heterogeneities. Dissolved CO2 in the glacial sand (5–10 m depth) created a plume of depressed pH (5.6–4.7), elevated EC (166–304 μS/cm) and concurrent increases in dissolved ion concentrations. EC was the most effective indicator for presence of dissolved CO2. Ionic concentration changes were generally slight with increases in Al, Ba, K, Na, Mg, Si, Sr and Zn forming the major changes. Water quality was not significantly affected and risks from small scale, short duration CO2 contamination appear minimal for this geological setting.
Studies with an Intravas Nylon Device in Rat* (2009)

Contraceptive efficacy of an intravas device (IVD) was investigated in rat. The IVD used consisted of a nylon suture which did not occlude the lumen of the vas completely and permitted a free passage of spermatozoa. Its presence for periods ranging from 15 to 180 days did not produce any changes in the histology of the testis and epididymis; In the vas deferens the tall columnar ciliated epithelium was replaced by squamous epithelium. A spermatic granuloma developed on the vas at the entry of the IVD and its frequency of occurrence and size increased with the passage of time. The device caused an increase in the vasal protein, sialic acid and phospholipid content, and a decrease in the level of glycogen and alkaline phosphatase activity at 15 days. The level of portein, glycogen and alkaline phosphatase activity returned to normalcy at 90 days but the sialic acid and phospholipid content remained elevated. Notwithstanding these alterations the device failed to affect the spermatozoal number, morphology, motility and their fertilizing ability. The significance of these findings is discussed.
Rubber Powder – A Perspective Filler of Thermoplastics (2005)

Abstract Rubber powder, ground at ambient temperature, was compounded with polypropylene using only 16 L/D of a co‐rotating twin screw extruder. An optimum of extruder configuration and selected process parameters were found for compounds with a rubber filling rate of 50 wt.‐%. Restrictions of a reactive compounding were taken into account. The dispersion of the rubber powder is not a limiting process. A compound containing 70 wt.‐% rubber powder showed to be overfilled.
Analysis of<i>S. pombe</i>SIN protein SPB-association reveals two genetically separable states of the SIN (2014)

The Schizosaccharomyces pombe septation initiation network (SIN) regulates cytokinesis, and asymmetric association of SIN proteins with the mitotic spindle pole bodies (SPBs) is important for its regulation. Here, we have used semi-automated image analysis to study SIN proteins in large numbers of wild-type and mutant cells. Our principal conclusions are: first, that the association of Cdc7p with the SPBs in early mitosis is frequently asymmetric, with a bias in favour of the new SPB; second, that the early association of Cdc7p-GFP to the SPB depends on Plo1p but not Spg1p, and is unaffected by mutations that influence its asymmetry in anaphase; third, that Cdc7p asymmetry in anaphase B is delayed by Pom1p and by activation of the spindle assembly checkpoint, and is promoted by Rad24p; and fourth, that the length of the spindle, expressed as a fraction of the length of the cell, at which Cdc7p becomes asymmetric is similar in cells dividing at different sizes. These data reveal that multiple regulatory mechanisms control the SIN in mitosis and lead us to propose a two-state model to describe the SIN.
Case Histories of Improved Horizontal Well Cleanup and Sweep Efficiency With Nozzle Based Inflow Control Devices (ICD) in Sandstone and Carbonate Reservoirs (2008)

Abstract This paper discusses the PLT-correlated results of two test wells completed during 2006; one in sandstone and one in a carbonate reservoir, with the new completion technology of nozzle-based passive inflow control devices (ICD) which improves performance of wells with reservoir challenges as described:In highly productive sandstone reservoirs, horizontal wells suffer from uneven flow profile and subsequent premature cresting/coning effects. In general, there is a tendency to produce more at the heel than at the toe of horizontal wells, which contributes to poor well cleanup at the toe. Additionally, excessively increasing the rate and/or horizontal well length can increase the risk of limiting sweep efficiency, resulting in bypassed reserves1.In carbonate reservoirs, permeability variations and fractures can cause uneven inflow profile and accelerate water and gas breakthroughs. Wells with early gas or water breakthrough have to be shut-in until remedial plans are decided and implemented, resulting in deferred production. The main reservoir objectives for applying passive ICD technology in the two test wells are:Sandstone: Decrease the influence of heel-toe effects and high permeability zones; hereby deferring water/gas breakthrough, improving well cleanup and sweep efficiency.Carbonate: Control flow rates from high permeability intervals and to limit production from each compartment based on lateral offset from the gas-oil contact to prevent premature gas breakthrough. The test well PLT-logs were correlated to static reservoir simulations. Analyses of the well performances show that the objectives of both completions were achieved. By having proper matches of the completions with ICD, the value over standard completions can be evaluated. Post-evaluation of the completion designs based on the PLT-log results has increased our understanding of the nozzle-based ICD performance. As a result several approaches for completing wells in both sandstone and carbonate reservoirs with ICD have been recommended in order to achieve optimized inflow performance. Introduction Two trial wells with nozzle-based passive ICD systems were designed and completed in 2006; one for sandstone and one for carbonate reservoirs. To evaluate and approve the new ICD completion, these wells were production logged and the results were carefully analyzed. The most important feature of the ICD completion is the self-adjusting effect of flow variations anywhere along the well trajectory and whenever they occur during entire well life. The key benefits are:Increased well life and reserves due to improved sweep efficiency.Delayed gas and water breakthrough.Decreased water/gas rates after breakthrough when water/gas mobility is higher than oil.Improved well cleanup.
Remote measurements of thundercloud electrostatic fields (2009)

Analytical and numerical models of the radio frequency emissions produced by relativistic runaway electron avalanches initiated by cosmic ray extensive air showers are presented. It is found that single‐point measurements of the distant electromagnetic fields allow the remote determination of the electrostatic field in the runaway electron avalanche region. For instance, it is possible to use ground‐based and/or remote airborne measurements of the radio frequency pulses from the runaway electron avalanches to map the magnitudes and directions of the electrostatic field within a thundercloud for regions with electric fields above the runaway avalanche threshold. Such measurements, which are difficult to perform in situ, may help answer several key questions regarding lightning initiation, such as what electric fields are usually present when lightning initiates and whether electric fields in small regions ever reach the conventional breakdown field.

The effect of temperature and pinning density on the critical current of a superconductor with a square periodic array of pinning sites (2005)

We have studied the effect of temperature and pinning density on the critical depinning force for several values of pinning strength through an extensive series of molecular dynamic simulations on driven vortex lattices interacting with square periodic arrays of pinning sites. We have solved the overdamped equation of vortex motion taking into account the vortex–vortex repulsion interaction, the attractive vortex pinning interaction, the thermal force, and the driving Lorentz force. We have found that the critical depinning force, as a function of the pinning density, may decrease, increase, or even remain constant, depending on the temperature and pinning strength values.
Large-aperture, wide-angle nonmechanical beam steering using polarization gratings (2016)

Liquid crystal polarization gratings (LCPGs) represent a relatively new technology capable of nonmechanically and efficiently steering light over a large field-of-regard in discrete steps. Due to their reliance on thin liquid crystal cells instead of mechanical moving parts, LCPG beam steering systems are attractive options for steering both active and passive optical sensors, especially in size, weight, and power (SWaP)-constrained platforms. This paper describes recent developments in large-aperture LCPG steering systems and summarizes the performance being achieved.
THE SHORT‐TERM EFFECT OF LASER TRABECULOPLASTY ON THE GLAUCOMATOUS VISUAL FIELD. A PROSPECTIVE STUDY USING COMPUTERIZED PERIMETRY (1984)

Several earlier studies have shown improvement of glaucomatous visual fields after pressure reduction achieved by acetazolamide or filtering surgery, while other studies have given conflicting results. In the present study laser trabeculoplasty was used to reduce the IOP in 42 eyes with glaucomatous visual field defects. Although good pressure reduction was achieved, no general regression of field defects was observed. The changes of the visual field were not correlated to the degree of pressure reduction. The results do not support the hypothesis that glaucomatous field defects are reversible when the IOP is reduced.
