GA based dynamic spectrum allocation in UHF-ISM band of 902&#x2013;928MHz with RADAR as primary user for cognitive radio (2013)

A novel integrated approach to Cognitive Radio environment with Radar signals of type linear frequency modulation (LFM) as Primary User (PU) is suggested in this paper. The approach consists of spectrum sensing of Radar signals through Wigner-Hough transformation process integrated with the learning and adaptation using Multi-Objective Genetic Algorithm (MOGA) for dynamic spectrum allocation. The objective of minimizing the interference in the presence of radar signal and maximizing the spectral efficiency when radar signal is not detected are considered. In addition, the objective of minimizing the power consumption is also considered. The functionality of the process considers the operation of NI-USRP <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">®</sup> device as SU and radar as PU over ISM-UHF band of 902-928MHz for attaining the fitness's of the SU parameters as desired. For validation, existing method for co-existence of SU with radar is compared for data-rate with the proposed method.
Adiabatic Triplet State Tautomerization of <i>p</i>-Hydroxyacetophenone in Aqueous Solution (2012)

The primary photophysical processes of p-hydroxyacetophenone (HA) and the ensuing proton transfer reactions in aqueous solution were investigated by picosecond pump-probe spectroscopy and nanosecond laser flash photolysis. Previous studies have led to mutually inconsistent conclusions. The combined data allow us to rationalize the excited-state proton transfer processes of HA in terms of a comprehensive, well-established reaction scheme. Following fast and quantitative ISC to the triplet state, (3)HA*, adiabatic proton transfer through solvent water simultaneously forms both the anion, (3)A(-)*, and the quinoid triplet enol tautomer, (3)Q*. The latter subsequently equilibrates with its anion (3)A(-)*. Ionization and tautomerization are likely to compete with the desired release reactions of p-hydroxyphenacyl photoremovable protecting groups.
Structured uncertainty analysis of robust stability for multidimensional array systems (2003)

This paper considers one of the fundamental issues in design and analysis of sampled multidimensional systems - that of uncertainty modeling and robust stability analysis. Methods of structured uncertainty analysis (/spl mu/-analysis) are extended toward systems with dynamical and noncausal spatial coordinates. The stability is understood in a broad sense and includes decay (localization) of system response along the noncausal spatial coordinates. Robustness of dynamical stability and spatial localization of response and boundary effects are addressed in a unified way. The main technical condition enabling the technical results of the paper is that the feedback loop including a multidimensional plant and controller does not have a feedthrough in the dynamical (time) coordinate sense. As an example, this paper applies the multidimensional structured uncertainty analysis to closed-loop control of a cross-directional paper machine process. The paper formulates multidimensional models of the process, its controller, and a structured uncertainty. The uncertainty corresponds to a combination of errors in the actuator mapping, the cross-directional response gain, and the response width.
Acyclic Diene Metathesis Polymerization of Divinylarenes and Divinylferrocenes with Grubbs-Type Olefin Metathesis Catalysts (2008)

1,4-Di(2-ethylhexyl)2,5-divinylbenzene, 1,4-di(2-ethylhexyloxy)-2,5-divinylbenzene, and 9,9-di(2-ethylhexyl)-2,7-divinylfluorene were synthesized from the respective dialdehydes and ADMET polymerized using Grubbs II or Grubbs−Hoveyda−Grela-type olefin metathesis catalysts. The continuous removal of ethene under a dynamic vacuum of 20 mbar at elevated temperatures in high boiling solvents (1,2-dichlorobenzene) resulted in the formation of long-chain poly[2,5-di(2-ethylhexyl)-p-phenylenevinylene] (Mn > 100 kDa, Pn = 330, Mw/Mn = 3.1) and poly[9,9-di(2-ethylhexyl)fluorenyl-2,7-vinylene] (Mn > 70 kDa, Pn = 178). The PPV forms a free-standing film after evaporation of a toluene solution. 1,3-(Diisopropenyl)ferrocene could not be polymerized in this manner; ferrocene-containing polymers were obtained with 1,1′-di(4-vinylphenyl)-3,3′,4,4′-tetramethylferrocene.
Short‐ and long‐term somatostatin analogue treatment in patients with hypoglycaemia related to endogenous hyperinsulinism (2007)

Long-term octreotide treatment can be used to control hypoglycaemia in patients with endogenous hyperinsulinism who are not eligible for surgery; octreotide efficacy on hypoglycaemia could be predicted by a short 100 microg-octreotide test in patients with benign insulinomas, but was not correctly predicted by Octreoscan scintigraphy.

Detection of DNA Damage and Identification of UV-Induced Photoproducts Using the CometAssay™ Kit (1999)

We introduce the first commercially available comet assay for the detection and quantification of DNA damage in individual eukaryotic cells. The major difficulty of the comet assay is the preparation of the slides needed to immobilize the samples throughout the lysis and electrophoretic procedures. The CometAssay kit uses a proprietary technology to precoat glass microscope slides to allow direct application of the agarose embedded sample without any additional slide treatment. In this report, we discuss the detection of DNA damage in individual cells exposed to ultraviolet irradiation using the new CometSlides and their cost compared to traditional slides.
Pharmacokinetic and pharmacodynamic effects of UK‐68,798, a new potential class III antiarrhythmic drug. (1991)

1. The pharmacokinetic and pharmacodynamic properties of UK-68,798, a novel selective potential class III antiarrhythmic agent, were studied in 18 patients with coronary artery disease. Three groups of four patients received intravenous doses of 1.5, 3.0 and 4.5 micrograms kg-1 respectively over 10 min. 2. UK-68,798 caused a mean increase in electrocardiographic QTc interval of 41, 40 and 81 ms, and in uncorrected QT interval of 36, 52 and 83 ms at the three dose levels. There were no significant effects on heart rate, blood pressure, PR interval and QRS duration. UK-68,798 was well tolerated with no significant adverse effects. 3. A dosing regimen using a loading infusion of two thirds of the total dose over 15 min with the remainder given over the following 45 min in six patients produced stable plasma concentrations and lengthening in QTc during the maintenance infusion. 4. There was a linear correlation between plasma concentration and change in QTc. The drug exhibited first-order kinetics with a mean clearance of 4.7 +/- 1.2 ml min-1 kg-1 and a mean terminal plasma half-life of 9.7 h. 5. UK-68,798 warrants further study as a selective potential Class III antiarrhythmic agent.
InterSense: Interconnect Performance Emulator for Future Scale-out Distributed Memory Applications (2015)

A common approach for improving application performance is to process its working set from memory. For datasets that do not fit into DRAM of a single machine this leads to a design of scale-out applications, where the application dataset is partitioned and processed by a cluster of machines. Performance of distributed memory applications, implemented using MPI (Message Passing Interface), inherently depends on performance of communication layer, which is largely defined by performance characteristics of underlying interconnect. During last couple years, many Big Data applications, e.g., Hadoop, Spark, Memcached, were re-written to take advantage of Remote Direct Memory Access (RDMA) technology and RDMA-capable interconnects which provide fast and high-bandwidth communications. The application analysis of potential performance improvements due to faster and higher bandwidth interconnects is a challenging task. Does the existing application implementation take a full advantage of the underlying interconnect or not? Will the application performance get worse if the interconnect has X% increased latency or Y% lower bandwidth? In this work, we introduce a novel emulation framework, called InterSense, which is implemented on top of existing high-speed interconnect, such as InfiniBand, and which provides two performance knobs for changing the interconnect bandwidth and latency. This approach offers an easy-to-use framework for a sensitivity analysis of complex distributed applications to communication layer performance instead of creating customized and time-consuming application models to answer the same questions. We evaluate the emulator accuracy with popular OSU MPI benchmarks: InterSense emulates the specified bandwidth and latency values with less than 2% error between the expected and measured values. We apply InterSense for sensitivity analysis of two new benchmarks, such as GUPS and Graph 500 to demonstrate the emulator's ease of use in getting non-trivial insights.
Optimising Networks Against Malware (2007)

Rapidly-spreading malicious software is an important threat on today's computer networks. Most solutions that have been proposed to counter this threat are based on our ability to quickly detect the malware-generated traffic or the malware instances themselves, something that in many cases can be beyond our ability. Nonetheless, it seems intuitive that certain defensive postures adopted in configuring networks or machines can have a positive impact on countering malware, regardless of our ability to detect it. It is thus important to quantitatively understand how changes in design and deployment strategies can affect malware performance; only then does it become possible to make optimal decisions. To that purpose, we study in this paper the impact of network interconnection topologies on the propagation of malware. We first use a theoretical model based on Markov processes to try to predict the progression of an infection under varying interconnection scenarios. We then compare these predictions with experimental results obtained by launching a malware emulation agent on three differently configured networks. Both theoretical and experimental results provide quantitative confirmation of the intuition that networks with higher degrees of interconnection allow faster spread of malware. In addition to this, we believe that the models, experimental methodology and tools described here can be safely and fruitfully used to study other aspects of malware performance, and hence of the relative effectiveness of defensive counter-measures.
Infection Control In Prosthodontics (2019)

Dental infection control and occupational safety are very important aspect of dentistry. It is essential to provide safe care to patient and at the same time not to be affected personally by occupational hazards. While patient safety addresses control of disease transmission to patient during care, occupational safety addresses control of occupational hazards to care provider.Dentist must follow effective infection control procedure in their practice. A positive step by step approach should be employed.This literature is to provide a background about the possible ways of transmission of infection, spreading, and procedures recommended for preventing their spread in the discipline of prosthodontics.
Novel Tetraspiroorthocarbonates as Successful Anti-shrinking Agents for the Photopolymerization of Epoxy Monomers (2012)

Abstract A pair of novel tetrafunctional spiroorthocarbonates (TETRASOC) was prepared in three stages. First, glycerol was reacted with tetraethyl orthocarbonate to form a pair of isomeric hemi spiroorthocarbonates (HEMI SOC-OLs) by monocyclization of glycerol. Formation of these two isomers depends on terminal or adjacent hydroxyl groups of glycerol reacting with the tetraethylorthocarbonate to form five and six-membered ring HEMI SOC-OLs. Second, the HEMI SOC-OLs were made to undergo another cyclization reaction by reacting with 1,3-propanediol, to form a pair of spiroorthocarbonates with one hydroxyl group (SOC-OL). In the third stage, the SOC-OL was used as nucleophylic reactant to displace the bromine atom of pentaerythritol bromide to form the final product TETRASOC. A volume change study was carried out to determine the efficiency of TETRASOC as an anti-shrinking additive finding that even at a low concentration of 7 mol%, it caused a 2.18% expansion of the polymeric volume of a bis epoxycyclohexane monomer (3,4-EP). Dynamic Mechanical Analysis (DMA) determined that the flexibilization induced by the TETRASOC in the polyether derived from 3,4-EP did not adversely impact the mechanical properties of the polymer.

Quantitative Phase Analysis by X-ray Diffraction of Multiphased Binary Alloy Coatings: Application to Brass Coating (1996)

A quantitative phase-analysis method is proposed to analyse by X-ray diffraction multiphased thin films obtained by diffusion. Intensity corrections taking into account the spatial distribution of the different phases, and computing of phase concentrations without standards are presented. It is shown that important errors can be made if one does not take the nonhomogeneity of phase distributions into account. As an example, the quantitative phase analysis of a brass layer obtained by a diffusion process is given.
Thermosensitive Polymeric Hydrogels As Drug Delivery Systems (2012)

Thermosensitive hydrogels are very important biomaterials used in drug delivery systems (DDSs), which gained increasing attention of researchers. Thermosensitive hydrogels have great potential in various applications, such as drug delivery, cell encapsulation, tissue engineering, and etc. Especially, injectable thermosensitive hydrogels with lower sol-gel transition temperature around physiological temperature have been extensively studied. By in vivo injection, the hydrogels formed non-flowing gel at body temperature. Upon incorporation of pharmaceutical agents, the hydrogel systems could act as sustained drug release depot in situ. Injectable thermosensitive hydrogel systems have a number of advantages, including simplicity of drug formulation, protective environment for drugs, prolonged and localized drug delivery, and ease of application. The objective of this review is to summarize fundamentals, applications, and recent advances of injectable thermosensitive hydrogel as DDSs, including chitosan and related derivatives, poly(N-isopropylacrylamide)-based (PNIPAAM) copolymers, poly(ethylene oxide)/poly(propylene oxide) (PEO/PPO) copolymers and its derivatives, and poly(ethylene glycol)/ biodegradable polyester copolymers.

Division of Labor: A More Effective Approach to Prefetching (2018)

Prefetching is a central component in most microarchitectures. Many different algorithms have been proposed with varying degrees of complexity and effectiveness. There are inherent tradeoffs among various metrics especially when we try to exploit both simpler access patterns and more complex ones simultaneously. Hypothetically, therefore, it is better to have collaboration of sub-components each specialized in exploiting a different access pattern than to have a monolithic design trying to have a similar prefetching scope. In this paper, we present some empirical evidence. We use a few components dedicated for some simple patterns such as canonical strided accesses. We show that a composite prefetcher with these components can significantly out perform state-of-the-art prefetchers. But more importantly, the composite prefetcher achieves better performance through a more limited prefetching scope while attaining a much higher accuracy. This suggests that the design can be more readily expanded with additional components targeting other patterns.
Texture synthesis via a noncausal nonparametric multiscale Markov random field (1998)

Our noncausal, nonparametric, multiscale, Markov random field (MRF) model is capable of synthesizing and capturing the characteristics of a wide variety of textures, from the highly structured to the stochastic. We use a multiscale synthesis algorithm incorporating local annealing to obtain larger realizations of texture visually indistinguishable from the training texture.

How to lease the internet in your spare time (2007)

Today's Internet Service Providers (ISPs) serve two roles: managing their network infrastructure and providing (arguably limited) services to end users. We argue that coupling these roles impedes the deployment of new protocols and architectures, and that the future Internet should support two separate entities: infrastructure providers (who manage the physical infrastructure) and service providers (who deploy network protocols and offer end-to-end services). We present a high-level design for Cabo, an architecture that enables this separation; we also describe challenges associated with realizing this architecture.
Projection-based disparity control for toed-in multiview images (2014)

The multiview images captured by toed-in camera array can reproduce the 3D scene vividly with appropriate positive, negative, and zero disparities. However, it is a challenging task to adjust the depth of the scene according to requirements of visual effects. In this paper, we propose a novel disparity control method based on projection to solve this problem. With the relationship between the world coordinate system and camera coordinate system, the zero disparity point in reference view is projected into other views. Thus, disparities of different views are obtained through matched corresponding points and views are shifted with calculated disparities. The proposed method is easy to implement, and the depth of toed-in multiview images can be adjusted as requirements. Experiment results show that the proposed method is effective in comparison to the conventional method, and the processed multiview images present desirable stereoscopic visual quality.
A digital envelope detection filter for real-time operation (1999)

A time-domain method to extract the envelope of an amplitude modulated signal at high speed is presented. This method, the envelope detection filter (EDF), is based on a nonlinear function of two consecutive samples of the input sequence. In spite of its simplicity, EDF provides a quite good approximation to the analytical signal magnitude for a wide range of signals and conditions. The paper presents the basis of the technique and analyzes the sources of error and its sensitivity to noise and signal bandwidth. Results of experiments with simulated signals are in good agreement with the theoretical model. Furthermore, EDF allows a straightforward implementation using a pipeline of two registers and a memory look-up table. The hardware implementation of EDP has been tested at a 10 MS/s, although current technology could achieve several times this throughput rate. Results obtained with EDF for real data of nondestructive testing experiments, are compared with those provided by the full precision analytical signal magnitude obtained by a software Hilbert transform. In all cases, no significant differences are appreciated between the analytical signal magnitude and the EDF output, which is computed in much less time.
Automatic calculation of electron density profiles from digital ionograms: 3. Processing of bottomside ionograms (1983)

Automatic scaling of bottomside Digisonde ionograms gives the E and F region echo traces with high accuracy. Polarization and incidence angle information in the ionogram enables the extraction of the vertical, ordinary polarization echo trace from quiet as well as disturbed ionograms. The scaling algorithm is tested with Digisonde ionograms from Goose Bay, Labrador, which show spread F about 50% of the time. Despite these disturbed conditions, f 0 F 2 is determined within ½ MHz for 475 ionograrns out of 577 during January 1980. A profile inversion algorithm calculates the electron density profile from the autoscaled h′( ƒ ) points. Parabolic profile shapes are assumed for the E region and the valley between the E and the F layer. The F layer is approximated by a single sum of Chebyshev polynomials, and the entire profile is described by a set of 16 numerical values. The CPU time required for ionogram scaling and electron density profile calculation is 14 s on a Cyber 71 computer. In addition to the profile the program outputs all relevant ionogram parameters: critical frequencies, minimum virtual heights, frequency and range spread, average echo amplitudes, and Doppler shifts.
