Design and implementation of a cache-based granular computing system (2007)

This paper presents a multilayer cache-based attribute granular computing system. It can be used to implement algorithms based on attribute granular computing. After defining an attribute granule, it brings forward an operation and storage model. Six basic mapping operations and three suitable storage patterns are designed for all kinds of attribute granular computing and storage. A cache-based storage management with schedule algorithm can improve the efficiency of data access and solve the problem which is caused by the limited memory capacity. Finally a hierarchy cache-based attribute granular computing system is implemented.
Analysis and optimal SAW ladder filter design including bonding wire and package impedance (2002)

This paper describes analysis and optimal design of SAW ladder filter, which includes effect of bonding wire and package impedance. Attenuation performance of SAW filter is influenced by not only their design conditions but also bonding wire effect and package design structure. To confirm their effect, theoretical and experimental analysis were studied, and it was found that electrical resonance generated by SAW element capacitance including capacitance of electrode fingers and stray capacitance, bonding wire and package inductance influence an attenuation characteristics. By using their characteristics effectively, we propose new improvement method of stop-band rejection.
The Lipid A 1-Phosphatase ofHelicobacter pyloriIs Required for Resistance to the Antimicrobial Peptide Polymyxin (2006)

Modification of the phosphate groups of lipid A with amine-containing substituents, such as phosphoethanolamine, reduces the overall net negative charge of gram-negative bacterial lipopolysaccharide, thereby lowering its affinity to cationic antimicrobial peptides. Modification of the 1 position of Helicobacter pylori lipid A is a two-step process involving the removal of the 1-phosphate group by a lipid A phosphatase, LpxEHP (Hp0021), followed by the addition of a phosphoethanolamine residue catalyzed by EptAHP (Hp0022). To demonstrate the importance of modifying the 1 position of H. pylori lipid A, we generated LpxEHP-deficient mutants in various H. pylori strains by insertion of a chloramphenicol resistance cassette into lpxEHP and examined the significance of LpxE with respect to cationic antimicrobial peptide resistance. Using both mass spectrometry analysis and an in vitro assay system, we showed that the loss of LpxEHP activity in various H. pylori strains resulted in the loss of modification of the 1 position of H. pylori lipid A, thus confirming the function of LpxEHP. Due to its unique lipid A structure, H. pylori is highly resistant to the antimicrobial peptide polymyxin (MIC > 250 microg/ml). However, disruption of lpxEHP in H. pylori results in a dramatic decrease in polymyxin resistance (MIC, 10 microg/ml). In conclusion, we have characterized the first gram-negative LpxE-deficient mutant and have shown the importance of modifying the 1 position of H. pylori lipid A for resistance to polymyxin.

Automated Microseismic Event Detection and Location by Continuous Spatial Mapping (2005)

Abstract Optimal control of oil-field hydraulic fracturing operations will benefit from reliable, automated, real-time microseismic monitoring. Existing microseismic processing techniques are often either unreliable, or impractical for real time use. In this paper we present the method of Coalescence Microseismic Mapping (CMMapping) for detection and localization of microseismic events. The technique is both automatic and robust, and explicitly allows for the inclusion of velocity model uncertainty into its formulation. We present the general basis for the method and illustrate its use on data acquired during a hydraulic fracture well stimulation.
Plant‐derived enzyme inhibitors and lectins for resistance against plant‐parasitic nematodes in transgenic crops (1998)

Due to increasing restrictions on the use of toxic and expensive nematicides, there is now a greater than ever need for crop cultivars that are resistant to plant-parasitic nematodes. Genetically engineered nematode resistance is not as well developed as other engineered traits but, even so, the first genetically modified plants with enhanced nematode resistance have been produced and tested. Plant-derived enzyme inhibitor and lectin genes are being evaluated for their ability to confer broad-spectrum nematode resistance in transgenic crop plants. Early indications are that these are likely to be effective. Gene pyramiding has potential to increase field durability and to widen the spectrum of nematodes controlled by any one transgenic line. © 1998 SCI.

THE 3MG TRIAL: A RANDOMISED CONTROLLED TRIAL OF INTRAVENOUS OR NEBULISED MAGNESIUM SULPHATE VERSUS PLACEBO IN ADULTS WITH SEVERE ACUTE ASTHMA (2013)

Objectives &amp; Background Previous studies suggest intravenous or nebulised magnesium sulphate may improve respiratory function in patients with acute asthma. We aimed to determine whether intravenous or nebulised MgSO 4 improve symptoms of breathlessness and reduce the need for hospital admission in adults with severe acute asthma. Methods In a double-blind, placebo-controlled trial, we enrolled adults with severe acute asthma at emergency departments of 34 UK hospitals. We excluded patients with life-threatening features. Allocated participants received IV MgSO 4 (2 g in 20 min) or nebulised MgSO 4 (3×500 mg doses in 1 h)+standard therapy, or placebo+standard therapy. We assessed two primary outcome measures in all participants according to treatment group: the proportion of patients admitted to hospital within 7 days and breathlessness measured on a 100 mm VAS in the 2 h after initiation of treatment. We adjusted for multiple testing. Study registration no: ISRCTN04417063 . Results 1109 patients were recruited (Jul 2008 to Jun 2012). 261 (79%) of 332 patients allocated nebulised MgSO 4 were admitted to hospital, as were 285 (72%) of 394 patients allocated intravenous MgSO 4 and 281 (78%) of 358 controls. Breathlessness was assessed in 296 (89%) patients allocated nebulised MgSO 4 , 357 (91%) patients allocated intravenous MgSO 4 , and 323 (90%) controls. Rates of hospital admission did not differ between patients treated with either form of MgSO 4 compared with controls or each other. Change in VAS breathlessness did not differ between active treatments and control, but change in VAS was greater for patients in the intravenous MgSO 4 group than the nebulised MgSO 4 group (5.1 mm, 0.8 to 9.4; p=0.019). Intravenous or nebulised MgSO 4 did not significantly decrease rates of hospital admission and breathlessness compared with placebo: intravenous MgSO 4 was associated with an odds ratio of 0.73 (95% CI 0.51 to 1.04; p=0.083) for hospital admission and a change in VAS breathlessness of 2.6 mm (−1.6 to 6.8; p=0.231) compared with placebo; nebulised MgSO 4 was associated with an odds ratio of 0.96 (0.65 to 1.40; p=0.819) for hospital admission and a change in VAS breathlessness of −2.6 mm (−7.0 to 1.8; p=0.253) compared with placebo. Conclusion These data suggest nebulised MgSO 4 has no role in the management of severe acute asthma in adults and at best suggest only a limited role for intravenous MgSO 4 in the ED.
Synthesis of new and unusual metal complexes form the reaction of dihalogen adducts of tertiary phosphines with unactivated metal powders (2007)

A review on the synthesis of metal complexes from dihalogen adducts of tertiary phosphines. It also discusses the activation of crude metal powders by reagents of PR3X2. The structural chem. of dihalogen adducts of tertiary phosphines is clearly diverse and is sensitive to the nature of R and X. Also the central atom E can play a crucial role, as can the solvent of prepn.
High efficiency, high-energy performance of an X-ray preionized Ar-Xe laser (1990)

Improved performance has been obtained from the X-ray preionized argon-xenon laser by using a spiker-sustainer circuit to efficiently pump the discharge. An output of 420 mJ was obtained from a 0.4-L active volume at 2-atm pressure with an overall efficiency of 1%. An efficiency of 4.1% due to the sustainer contribution alone was also realized.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Source coding by efficient selection of ground-state clusters (2005)

We analyze the geometrical structure of clusters of ground states which appear in many frustrated systems over random graphs. Focusing on the regime of connectivities where the number of clusters is exponential in the size of the problems, we identify an appropriate generalization of the survey propagation equations efficiently exploring the geometry. The possibility of selecting different clusters has also computational consequences. As a proof of concept here we show how a well-known physical system can be used to perform nontrivial data compression, for which we introduce a unique compression scheme. Performances are optimized when the number of well-separated clusters is maximal in the underlying physical model.
KSHV Latency Locus Augments B Cell Response In Vivo (2011)

Abstract Abstract 1115 A small subset of genes is transcribed during latency in Kaposi sarcoma-associated herpesvirus (KSHV) lymphomas. To better understand viral lymphomagenesis we generated a transgenic mouse expressing all viral latent genes including LANA, vFLIP, vCyc, kaposin and all viral miRNAs. All viral miRNAs were expressed in B cells. The complete latency locus induced activation of mature B cells more robustly than a single LANA protein transgenic mouse. It led to the specific expansion of marginal zone (MZ) B cells. The transgenic mice showed an augmented primary response to T-dependent antigen leading to acute MZ activation and germinal center (GC) activation. Furthermore, they exhibited an augmented response to TLR4 stimulation. Our data indicates that the KSHV latency locus fuels transformation processes as a chronic antigenic stimulator. These data supports a model of lymphomagenesis, in which virally infected B cells become hyperresponsive to B cell stimulation, thus providing an expanded pool for secondary genetic alterations.

Photon-assisted ultrafast plasma expansion in GaAs (2004)

This study deals with the ultrafast electron-hole plasma expansion of photo-excited carriers in GaAs. This work applies a novel experimental scheme for optical pump-terahertz probe (OPTP) measurements where the state of the photo-excited layer close to the sample surface is probed by means of an internal reflection of a picosecond terahertz (THz) pulse. This approach allows direct probing of the photo-excited layer from its back side. In conjunction with the possibility of phase-sensitive detection of THz pulses, the authors are able to observe the motion of the interface separating the excited and non-excited part of the sample.
On-chip linear voltage regulator module (VRM) effect on power distribution network (PDN) noise and jitter at high-speed output buffer (2015)

In this paper, the reduction of power distribution network noise and jitter at high-speed output buffer by using on-chip linear voltage regulator module circuit is introduced and analyzed. The transient response of typical on-chip linear VRM circuit is analyzed in power gating condition. When the on-chip linear VRM circuit is inserted between on-chip PDN and operating high-speed output buffers, the on-chip PDN noise and jitter at output buffer are significantly reduced. The larger on-chip decoupling capacitor leads to the lower PDN noise generated by on-chip linear VRM circuit. The on-chip linear VRM also reduces the impact of the aggressor buffer to the victim buffer in different PDN, resulting in the improved performance of the victim buffer. Reduction of PDN noise and jitter at output buffer using on-chip linear VRM are validated based on SPICE simulation with 110 nm CMOS technology library.
UIML Based Design of Multimodal Interactive Applications with Strict Synchronization Requirements. (2009)

As the variety in network service platforms and end user devices grows rapidly, content providers must constantly adapt their production system to support these new technologies. In this paper, we present a middleware platform for deploying highly interactive (television) applications over a diverse collection of networks and end user devices. As the user interface of such interactive applications may vary depending on the capabilities of the different target devices, our middleware uses UIML for the description of generic user interfaces. Our middleware platform also provides a pluggable support for new networks. A factor that highly complicates the design is the need for strict synchronization between an interactive application and video or audio data that is broadcasted. In order to support a maximum of functionality, downloadable application logic is used to provide the interactive services. As a test case, an evaluation setup was built, targeting both set-top boxes and mobile phones.

Noninvasive Assessment of Portal Hypertension–Can US Aid in the Prediction of Portal Pressure and Monitoring of Therapy? (2006)

A method that could be used to accurately assess portal venous pressure would be valuable when diagnosing portal hypertension, evaluating patient prognosis, and monitoring the progress of therapy. Baik et al have suggested that a qualitative noninvasive Doppler US parameter can be used to monitor therapy of portal hypertension. Further clinical investigation is needed to confirm these results and to determine whether hepatic venous Doppler waveform tracings can be used to monitor patient response to therapy. Ongoing research suggests that microbubble contrast agents may enable a more quantitative noninvasive estimate of intravascular pressures with US.
Implementation of redox gradients in hydrogen bonded complexes containing N,N-dimethylaniline, flavin and fullerene derivatives (2009)

A variety of supramolecular complexes were formed by associating an electron donor-substituted flavin dyad (10-[4′-(N,N-dimethylamino)phenyl]isoalloxazine: DMA–Fl) and a family of fullerene derivatives that contain single and double hydrogen bond receptors (SRC60 and DRC60). The stoichiometry of the corresponding complexes, that is, DMA–Fl and SRC60 or DRC60, were examined by Job's plot analysis of the absorption changes linked to DMA–Fl at 470 nm. To this end, 1 : 1 and 1 : 2 complex stoichiometries were determined for DMA–Fl-SRC60 and (DMA–Fl)2-DRC60, respectively. Molecular aggregates in the form of remarkably stable clusters were formed by the fast injection method. Insights into these clusters came from transmission electron microscopy (TEM) measurements, which revealed network configurations for (DMA–Fl-SRC60)n with diameters in the range between 200 and 500 nm, while uniform nanoparticles of about 40 nm diameter were discernible for [(DMA–Fl)2-DRC60]n. The highly colored composite clusters were assembled onto an optically transparent electrode covered with nanostructured SnO2 films by the electrophoretic deposition technique. Important are the photocurrent action spectra providing maximum IPCE values that are twice as high for [(DMA–Fl)2-DRC60]n than for (DMA–Fl-SRC60)n. To complement these studies the dynamics of electron transfer were investigated by femtosecond laser flash photolysis in the supramolecular clusters (i.e., (DMA–Fl-SRC60)n and [(DMA–Fl)2-DRC60]n). As a matter of fact, for the first time we were able to demonstrate the unidirectional electron transfer from the terminal electron donor (N,N-dimethylaniline) moiety to the terminal electron acceptor (fullerene) moiety.
Modulation response of double tunneling-injection quantum dot lasers (2016)

The upper limit for the modulation bandwidth in a double tunneling-injection (DTI) quantum dot (QD) laser is discussed. While the maximum bandwidth is the same in DTI and conventional QD lasers, the optimum dc current, at which it is obtained, is lower in a DTI laser. Different factors limiting the modulation bandwidth in a DTI QD laser are also discussed.
Diesel-Based Gel Concentrate Improves Rocky Mountain Region Fracture Treatments (1988)

ABSTRACT More than 500 oil and gas wells in the Denver-Julesburg (D-J) Basin have been successfully stimulated using a water-base fracturing fluid, gelled with a diesel-base gel concentrate. Since the use of this system began in 1985, six different D-J Basin formations, with bottom hole temperatures ranging from 120°F to 260°F, have been treated. Ammonium chloride and potassium chloride have both been used with the continuously mixed gel to help protect clays. This paper presents a brief description of the chemistry of the system, however, the main emphasis of the paper is toward operational considerations and economics of using diesel-based gel concentrate. The considerations include continuous (on-the-fly) mixing of the gel and an evaluation of ammonium chloride versus potassium chloride for clay protection.

Long term spectrum survey of the 2.4 GHz ISM band in multiple hospital environments (2016)

Wireless technology has become an invaluable facilitator in many aspects of daily life. Healthcare environments in particular have gained noticeable agility and flexibility by integrating wireless functionality into various medical equipment. As of late, chipsets designed to implement communication standards in the Industrial, Scientific and Medical (ISM) band have become inexpensive and widely available, making wireless-enabled medical devices reach increased number of users. However, the sharp increase in the number of operating nodes now occupying the ISM band has resulted in a cluttered spectrum with limited resources in many environments. In this paper, we report on a long term spectrum survey of the ISM band in both an intensive care unit (ICU) and a post-surgery recovery room (RR). Both spaces were concurrently surveyed for 28 consecutive days capturing spectrum occupancy on every weekday four times. Results indicate that spectrum occupancy patterns are location dependent. Examined sub-channels with significant correlation in activity pattern corresponded mainly to IEEE 802.11 channels 1, 6, and 11. Low daily duty cycle is indicated at a maximum of 5.17% at RR and 3.11% at ICU.
