Electrical conductivity of titanium dioxide layers doped with vanadium, cobalt, and niobium (2012)

Much attention to electrical properties of titanium dioxide is due to the fact that it has recently started to be used in the manufacture of various electronic devices. Temperature dependences of the directcurrent (DC) and alternating-current (AC) conductivities of titanium dioxide layers doped with vanadium, as well as simultaneously with cobalt and niobium, are studied. The layers were produced by the high-frequency magnetron deposition in an oxygen/argon environment at a temperature of 550°C, vacuum of 2 × 10−2 Torr, and a 0.07-nm/s deposition rate. Below room temperature, the electrical conductivity of vanadium-doped titanium dioxide is specified by a variable range-hopping conduction. The localized state density is estimated at the Fermi level. A tunneling conductance with thermal activation of carriers between clusters, presumably cobalt clusters, is detected for samples doped with cobalt and niobium. It is shown that the measurement of the dependence of the electrical resistance on the temperature is a fast and reliable method for determining the presence of clusters in a material.
A microscopic investigation of bubble formation nuclei (1984)

Numerous experiments suggest that bubble formation in aqueous media is initiated by stable gas nuclei. Although attempts have been made both to detect and to describe these entities, their very existence is still controversial. This paper reports a detailed investigation using light and electron microscopes. The objects identified as nuclei are found in both distilled water and gelatin, and they resemble ordinary gas bubbles. Radii are on the order of 1 μm or less and can be three orders of magnitude smaller. The number density decreases exponentially with increasing radius. A gas filling is implied by the observation that nuclei expand when the pressure decreases and contract when it rises. The occurrence of nuclear clusters and of binary or osculating nuclei suggests that stabilization is achieved via surfactant films. The monolayer thickness of these films, estimated from the thicknesses of bilayer septa, is (20±7) Å. Many nuclei are embedded in reservoirs of surface-active material made visible by osmium–tetroxide staining. Electron microscope sections are hardened by infiltrating gelatin with epoxy. Reservoirs, encased in epoxy, form microbubble chambers in which the coalescence and bursting of nuclei can be studied during extended exposures to the electron beam.
Synthesis and turnover of collagen precursors in rabbit skin (1967)

1. The rate of synthesis of [(14)C]hydroxyproline by rabbit skin was studied in vitro and in vivo. 2. The soluble collagen fractions were shown to have a very rapid turnover. The 0.15m-sodium chloride-extractable collagen showed t((1/2)) values of 1.2hr. in vitro and 12hr. in vivo. The 0.5m-sodium chloride-extractable collagen exhibited a t((1/2)) value of 20hr. in vivo. 3. Under the conditions used it was not possible to obtain radioactive insoluble collagen in vitro. 4. A significant amount of soluble collagen is lost before it becomes insoluble. 5. These observations may help to explain why large amounts of peptide-bound hydroxyproline appear in the urine during periods of rapid collagen synthesis.
Oral Sildenafil in Infants With Persistent Pulmonary Hypertension of the Newborn: A Pilot Randomized Blinded Study (2006)

Oral sildenafil was administered easily and tolerated as well as placebo and improved OI in infants with severe PPHN, which suggests that oral sildenafil may be effective in the treatment of PPHN and underscores the need for a large, controlled trial.
University MSO: an academic medical center's managed care strategy. (1997)

In all markets of the country, academic medical centers (AMCs) are organizing their response to increasing managed care penetration. This is true in New York City, home of six academic medical centers, as well as in the New York metropolitan, tristate area with a total of nine AMCs. The adaptable structure of a management services organization (MSO) offers the AMC the mechanism to position itself in the managed care market, to integrate its institutions and physician practices, and to link community physicians, affiliated institutions, and ancillary service providers. This article describes the approach used by New York University Medical Center and its clinical faculty to form an MSO and the MSO's strategic expectations for the future.
A Layered Communication Architecture for the Support of Crisis Response (1997)

:Crises, situations characterized by high consequence, low probability, and short decision time, create a unique and threatening decision-making environment that must be conscientiously supported. The aim of this study is to derive a prescriptive architecture for crisis response systems, in particular, the role of communication and the characteristics of communication systems that are needed to connect the decision-making elements of crisis response.The layered crisis communication architecture (CCA) detailed in this paper enumerates the communication functionality required of any crisis response system. To support the crisis-handling team adequately during crisis response, such systems must include the services of each of the described six layers: The base, or connectivity, layer interfaces with the ISO’s OSI model to provide error-free end-to-end message transfer. The data-validation layer protects against incorrect data sources through gathering information to corroborate an incoming message. The filtering layer organizes and synthesizes messages to ensure that the crisis-handling team is presented with relevant data in a meaningful, usable form. The values layer interprets messages based on preestablished crisis priorities. The organizational memory layer provides decision makers with access to relevant data and knowledge bases. The group process layer supports the communication, coordination, and collaboration among the crisishandling team members. To support crisis response adequately, these six layers of the CCA must be implemented as a single, cohesive whole.Through the CCA, the study offers pragmatically sound principles for organizing crisis response systems and captures a comprehensive perspective of the crisis response process; that is, this work offers a system architecture. As an architecture, the model enumerates all the functions necessary to support crisis response communication effectively.
Performance Analysis Of Music, Root-Music And Esprit Doa Estimation Algorithm (2014)

Direction of Arrival estimation refers to defining a mathematical function called a pseudospectrum that gives an indication of the angle a signal is impinging on the antenna array. This estimation is an efficient method of improving the quality of service in a communication system by focusing the reception and transmission only in the estimated direction thereby increasing fidelity with a provision to suppress interferers. This improvement is largely dependent on the performance of the algorithm employed in the estimation. Many DOA algorithms exists amongst which are MUSIC, Root-MUSIC and ESPRIT. In this paper, performance of these three algorithms is analyzed in terms of complexity, accuracy as assessed and characterized by the CRLB and memory requirements in various environments and array sizes. It is found that the three algorithms are high resolution and dependent on the operating environment and the array size.
Prevalence and treatment of spasticity reported by multiple sclerosis patients (2004)

The objective of this study was to characterize the population of multiple sclerosis (MS) patients suffering from spasticity and to evaluate treatment patterns, including intrathecal baclofen (ITB) delivery, related to patient quality of life (QOL). We conducted a cross-sectional, two-level study using data from the Patient Registry of the North American Research Committee on MS (NARCOMS). In addition, we surveyed a subgroup of 198 preselected patients who are using ITB (ITBG) and a random sample of 315 oral drug users (ORALG). Among the registrants, 16% reported no spasticity, 31% minimal, 19% mild, 17% moderate (frequently affects activities), 13% severe (daily forced to modify activities) and 4% total (prevents daily activities). Patients experiencing greater severity included by proportion males, and those older and with longer duration of MS. QOL scores decreased inversely with severity. In the focused survey, ITBG reported lower levels of spasticity than ORALG, less stiffness in the legs, less pain and fewer spasms at any time. They scored significantly lower in the SF-36 physical component, yet reported less fatigue on the MFIS scale. Prevalence data reveal that one third of MS patients modify or eliminate daily activities as a result of spasticity. Treatment of spasticity can significantly impact QOL parameters by reducing spasms, pain and fatigue.
Secure IoT for a Pervasive Platform (2018)

Nowadays, the proliferation of smart, communication-enable devices is opening up many new opportunities of pervasive applications. A major requirement of pervasive applications is to be secured. The complexity to secure pervasive systems is to address a end-to-end security level: from the device to the services according to the entire life cycle of devices, applications and platform. In this article, we propose a solution combining both hardware and software elements to secure communications between devices and pervasive platform based on certificates issued from a Public Key Infrastructure. Our solution is implemented and validated with a real device extended by a secure element and our own Public Key Infrastructure.

Integrating well log interpretations for lithofacies classification and permeability modeling through advanced machine learning algorithms (2017)

In this paper, an integrated procedure was adopted to obtain accurate lithofacies classification to be incorporated with well log interpretations for a precise core permeability modeling. Probabilistic neural networks (PNNs) were employed to model lithofacies sequences as a function of well logging data in order to predict discrete lithofacies distribution at missing intervals. Then, the generalized boosted regression model (GBM) was used as to build a nonlinear relationship between core permeability, well logging data, and lithofacies. The well log interpretations that were considered for lithofacies classification and permeability modeling are neutron porosity, shale volume, and water saturation as a function of depth; however, the measured discrete lithofacies types are sand, shaly sand, and shale. Accurate lithofacies classification was achieved by the PNN as the total percent correct of the predicted discrete lithofacies was 95.81%. In GBM results, root-mean-square prediction error and adjusted R-square have incredible positive values, as there was an excellent matching between the measured and predicted core permeability. Additionally, the GBM model led to overcome the multicollinearity that was available between one pair of the predictors. The efficiency of boosted regression was demonstrated by the prediction matching of core permeability in comparison with the conventional multiple linear regression (MLR). GBM led to much more accurate permeability prediction than the MLR.

CoMFA-Based Prediction of Agonist Affinities at Recombinant Wild Type versus Serine to Alanine Point Mutated D2 Dopamine Receptors (2000)

Agonist affinity changes dramatically as a result of serine to alanine mutations (S193A, S194A, and S197A) within the fifth transmembrane region of D2 dopamine receptors and other receptors for monoamine neurotransmitters. However, agonist 2D-structure does not predict which drugs will be sensitive to which point mutations. Modeling drug-receptor interactions at the 3D level offers considerably more promise in this regard. In particular, a comparison of the same test set of agonists across receptors differing minimally (point mutations) offers promise to enhance the understanding of the structural bases for drug-receptor interactions. We have previously shown that comparative molecular field analysis (CoMFA) can be applied to comparisons of affinity at recombinant D1 and D2 dopamine receptors for the same set of agonists, a differential QSAR. Here, we predicted agonist K(L) for the same set of agonists at wild type D2 vs S193A, S194A, and S197A receptors using CoMFA. Each model used bromocriptine as the template. ln(1/K(L)) values for the low-affinity agonist binding conformation at recombinant wild type and mutant D2 dopamine receptors stably expressed in C6 glioma cells were used as the target property for the CoMFA of the 16 aligned agonist structures. The resulting CoMFA models yielded cross-validated R(2) (q(2)) values ranging from 0.835 to 0.864 and simple R(2) values ranging from 0.999 to 1.000. Predictions of test compound affinities at WT and each mutant receptor were close to measured affinity values. This finding confirmed the predictive ability of the models and their differences from one another. The results strongly support the idea that CoMFA models of the same training set of compounds applied to WT vs mutant receptors can accurately predict differences in drug affinity at each. Furthermore, in a "proof of principle", two different templates were used to derive the CoMFA model for the WT and S193A mutant receptors. Pergolide was chosen as an alternate template because it showed a significant increase in affinity as a result of the S193A mutation. In this instance both the bromocriptine- and pergolide-based CoMFA models were similar to one another but different from those for the WT receptor using bromocriptine- or pergolide- as templates. The pergolide-based S193A model was more strikingly different from that of the WT receptor than was the bromocriptine-based S193A model. This suggests that a "dual-template" approach to differential CoMFA may have special value in elucidating key differences across related receptor types and in determining important elements of the drug-receptor interaction.

Electrochemical Studies of Polyaniline in a Gel Polymer Electrolyte (2002)

Studies on redox supercapacitors employing electronically conducting polymers are of great importance for hybrid power sources and pulse power applications. In the present study, polyaniline (PANI) has been potentiodynamically deposited on stainless steel substrate and characterized in a gel polymer electrolyte (GPE). Use of the GPE facilitates a voltage limit of the capacitor to 1 V, instead of 0.75 V in aqueous electrolytes. From charge-discharge studies of the solid-state PANI capacitors, a specific capacitance of has been obtained at a specific power of of PANI. The values of specific capacitance and specific power are considerably higher than those reported in the literature. High energy and high power characteristics of the PANI are presented. © 2002 The Electrochemical Society. All rights reserved.
Asymmetric optical image encryption using random Hilbert mask based on fast walsh hadamard transform (2017)

A new image asymmetric encryption technique using Radial Hilbert mask (RHM) based on Fast Walsh Hadamard Transform (FWHT) is proposed for security enhancement. In this technique, bits of the secret image to be transmitted is randomized by shuffling the bits randomly. The obtained scrambled image is then masked with RHM and random phase mask (RPM) using asymmetric encryption in FWHT domain to get final encrypted image. FWHT has been used in the cryptosystem as protects from the quantization error and image can be perfectly reconstructed. The proposed scheme also includes RHM which increases the key space and makes it robust to many attacks. The proposed cryptosystem's robustness has been analyzed on the basis of different parameters by simulating on MATLAB 8.1.0 (R2012b). The simulation result highlights the robustness, suitability and effectiveness of the proposed cryptosystem.

The destruction by microwave radiation of bacterial endospores and amplification of the released DNA (1998)

Endospores from Bacillus megaterium NCIMB 7581, B. stearothermophilus NCIMB 8922, Clostridium sporogenes NCIMB 8053 and Thermoanaerobacterium thermosaccharolyticum NCIMB 9385 were subjected to varying regimes of microwave radiation under controlled conditions. The effects of this form of thermal excitation were studied in terms of morphological changes (light and electron microscopy) and also release of constituents (DNA and calcium ions) from the core of the spore. Spores which are highly resistant to conventional heating such as autoclaving were fragmented by microwaves, albeit only at a greater intensity than was required for spores of mesophilic species. Spores of B. sphaericus NCTC 9602 and of a mutant, which contains 30% of the dipicolinic acid (DPA) of the parent, showed identical profiles of disruption with respect to time and temperature. It is unlikely therefore that DPA plays any role in the thermal excitation of the core. The DNA liberated by microwaving spores was amplifiable by polymerase chain reaction; the rapid identification of spores in the food and pharmaceutical industries is thus possible using this approach.
Exact Solutions of a Generalized Weighted Scale Free Network (2013)

We investigate a class of generalized weighted scale-free networks, where the new vertex connects to m pairs of vertices selected preferentially. The key contribution of this paper is that, from the standpoint of random processes, we provide rigorous analytic solutions for the steady state distributions, including the vertex degree distribution, the vertex strength distribution and the edge weight distribution. Numerical simulations indicate that this network model yields three power law distributions for the vertex degrees, vertex strengths and edge weights, respectively.
Preparation and characterization of organic-inorganic hybrid membranes (2001)

To achieve organic mixture separation at higher temperatures, organic inorganic hybrid membranes were prepared from 3 aminopropyltriethoxysilane(APST) and terephthaloyl chloride (CTPH) membrane material using the Sol Gel method. Experiments showed that many factors, such as acid content, solution concentration, hydrolysis time, temperature and type of support membranes, can affect the preparation process. The mechanical properties, heat resistance and structure of the membrane were characterized and analyzed. Experimental results showed that the membrane has good heat resistance with a decomposition temperature around 333 ℃. The polytetra fluor ethylene (PTFE) microporous membrane is an ideal support for the active layer except that the membrane is brittle.
