The UAV Low Elevation Propagation Channel in Urban Areas: Statistical Analysis and Time-Series Generator (2013)

In this paper we analyze the fading statistics of the link between a remotely controlled flying platform or an Unmanned Aerial Vehicle (UAV) and a ground receive station in an urban area. This link has a very specific geometry which is somewhere in between that of the purely terrestrial case (e.g., a macro-cell) and that of the land mobile satellite (LMS) systems. We have performed a model-based statistical analysis using unique experimental data, and following well-known models for LMS and terrestrial links with the conclusion that the Loo <citerefgrp xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><citeref refid="ref1"/></citerefgrp> (Rice+log-normal) model is the most suitable starting point for developing the wanted model; then several modifications have been introduced achieve a better match. Finally, we developed a narrowband time-series generator capable of reproducing the observed signal dynamics.
Polyhedral oligomeric silsesquioxane nanocomposites exhibiting ultra-low dielectric constants through POSS orientation into lamellar structures (2009)

Polyhedral oligomeric silsesquioxane (POSS) nanocomposite, which is prepared from two liquid monomers and can be processed under the “spinning on” process, exhibits an ultra-low dielectric constant (k) of 1.47. The ultra-low k value of the POSS nanocomposite material is attributed to the formation of a POSS lamellar structure. The nanocomposite material also shows good thermal stability, high glass transition temperature, and re-workable characteristics, warranting its high potential for uses in modern and future microelectronics.
Know Your Standard: Clarifying the CIE Erythema Action Spectrum (2010)

The standard erythema action spectrum provides an internationally accepted representation of the erythema-inducing effectiveness of wavelengths in the UV part of the spectrum. The action spectrum forms the basis of the UV index used for public health information, defines the standard erythema dose unit and the minimum erythema dose and is the default response spectrum aspired to by a range of UV radiometer manufacturers. However, there are several versions of this erythema action spectrum in use, and only one of them has been endorsed as a standard. While the differences in erythemally weighted radiation incurred by choice of action spectrum will be no more than a few percent, this uncertainty is unnecessary. Here we detail the differences in the different versions of erythema action spectra, illustrate the resulting effects in quantifying UV doses and encourage readers to use only the standard version of the action spectrum in the future.
Routing in Sparse Vehicular Ad Hoc Wireless Networks (2007)

A vehicular ad hoc network (VANET) may exhibit a bipolar behavior, i.e., the network can either be fully connected or sparsely connected depending on the time of day or on the market penetration rate of the wireless communication devices. In this paper, we use empirical vehicle traffic data measured on 1-80 freeway in California to develop a comprehensive analytical framework to study the disconnected network phenomenon and its network characteristics. These characteristics shed light on the key routing performance metrics of interest in disconnected VANETs, such as the average time taken to propagate a packet to disconnected nodes (i.e., the re-healing time). Our results show that, depending on the sparsity of vehicles or the market penetration rate of cars using Dedicated Short Range Communication (DSRC) technology, the network re-healing time can vary from a few seconds to several minutes. This suggests that, for vehicular safety applications, a new ad hoc routing protocol will be needed as the conventional ad hoc routing protocols such as Dynamic Source Routing (DSR) and Ad Hoc On-Demand Distance Vector Routing (AODV) will not work with such long re-healing times. In addition, the developed analytical framework and its predictions provide valuable insights into the VANET routing performance in the disconnected network regime.
Network Analyses Reveal Pervasive Functional Regulation Between Proteases in the Human Protease Web (2014)

Proteolytic processing is an irreversible posttranslational modification affecting a large portion of the proteome. Protease-cleaved mediators frequently exhibit altered activity, and biological pathways are often regulated by proteolytic processing. Many of these mechanisms have not been appreciated as being protease-dependent, and the potential in unraveling a complex new dimension of biological control is increasingly recognized. Proteases are currently believed to act individually or in isolated cascades. However, conclusive but scattered biochemical evidence indicates broader regulation of proteases by protease and inhibitor interactions. Therefore, to systematically study such interactions, we assembled curated protease cleavage and inhibition data into a global, computational representation, termed the protease web. This revealed that proteases pervasively influence the activity of other proteases directly or by cleaving intermediate proteases or protease inhibitors. The protease web spans four classes of proteases and inhibitors and so links both recently and classically described protease groups and cascades, which can no longer be viewed as operating in isolation in vivo. We demonstrated that this observation, termed reachability, is robust to alterations in the data and will only increase in the future as additional data are added. We further show how subnetworks of the web are operational in 23 different tissues reflecting different phenotypes. We applied our network to develop novel insights into biologically relevant protease interactions using cell-specific proteases of the polymorphonuclear leukocyte as a system. Predictions from the protease web on the activity of matrix metalloproteinase 8 (MMP8) and neutrophil elastase being linked by an inactivating cleavage of serpinA1 by MMP8 were validated and explain perplexing Mmp8-/- versus wild-type polymorphonuclear chemokine cleavages in vivo. Our findings supply systematically derived and validated evidence for the existence of the protease web, a network that affects the activity of most proteases and thereby influences the functional state of the proteome and cell activity.
Large-area microelectrode arrays for recording of neural signals (2004)

To understand the neural code, that the retina uses to communicate the visual scene to the brain, large-area microelectrode arrays are needed to record retinal signals simultaneously from many recording sites. This will give a valuable insight into how large biological neural networks (such as the brain) process information, and may also be important in the development of a retinal prosthesis as a potential cure for some forms of blindness. We have used the transparent conductor indium tin oxide to fabricated electrode arrays with approximately 500 electrodes spaced at 60 /spl mu/m. The fabrication procedures include photolithography, electron-beam lithography, chemical etching and reactive-ion etching. These arrays have been tested electrically using impedance measurements over the range of frequencies important when recording extracellular action potentials (0.1-100kHz). The data has been compared to a circuit model of the electrode/electrolyte interface. One type of array (512 electrodes) behaves as theory would dictate and exhibits an impedance of 200 k/spl Omega/ at 1kHz. The other array (519 electrodes) has an impedance of 350 k/spl Omega/ at this frequency, which is higher than predicted by the models. This can perhaps be attributed to the difference in fabrication techniques. The 512-electrode array has been coupled to low-noise amplification circuitry and has recorded signals from a variety of retinal tissues. Example in vitro recordings are shown here.
<title>Membrane mechanism of low-intensity laser biostimulation on a cell</title> (2000)

More than one function of a cell can be influenced by low intensity laser (LIL) irradiation, but the others remained unchanged when one function of the cell was altered by LIL irradiation. This phenomenon has been explained by the signal transduction mechanism (STM) on LIL biomodulation. It has been shown in this paper, the membrane receptors collectively mediate STM; as the frequency of the absorption light of membrane receptors is greater than the one of visible laser irradiation, the membrane absorption of visible light is non-resonant, and its transition rate is extraordinarily small, but can be amplified by the coherent state of the identical and independent membrane receptors of a pathological cell.
Determination of high density lipoprotein cholesterol in venous and capillary whole blood. (1988)

A procedure is presented and evaluated for separation of plasma high density lipoprotein from either capillary or venous whole blood. The lipoprotein is separated by adding 50 microliter of sample to 250 microliter of 0.15 M NaCl solution containing 99.9 g/l polyethyleneglycol 6000, 0.0374 g/l dextran sulfate (Mr 15,000) and 2.6 mM Mg2+. After gentle mixing for a few minutes and standing 10 min at room temperature, mixtures are centrifuged (1,500 g) for 10 min and cholesterol is measured on 200 microliter of supernatant by an enzymatic-colorimetric method. Comparison studies demonstrate a good correlation between high density lipoprotein cholesterol in plasma and capillary or venous whole blood. The procedure is simple, has the advantage of using either K3-EDTA-anticoagulated whole blood, without the need of centrifugation, or capillary whole blood which can also be collected away from the laboratory.

Mixed reality in education, entertainment, and training (2005)

Transferring research from the laboratory to mainstream applications requires the convergence of people, knowledge, and conventions from divergent disciplines. Solutions involve more than combining functional requirements and creative novelty. To transform technical capabilities of emerging mixed reality (MR) technology into the mainstream involves the integration and evolution of unproven systems. For example, real-world applications require complex scenarios (a content issue) involving an efficient iterative pipeline (a production issue) and driving the design of a story engine (a technical issue) that provides an adaptive experience with an after-action review process (a business issue). This article describes how a multi-disciplinary research team transformed core MR technology and methods into diverse urban terrain applications. These applications are used for military training and situational awareness, as well as for community learning to significantly increase the entertainment, educational, and satisfaction levels of existing experiences in public venues.
Some important properties of strandboard manufactured from bamboo (2006)

Bamboo has received increasing attention as an alternative raw material for use in the manufacture of composite boards. Random strandboards were made using a moso bamboo (Pyllostachys pubescent Mezel) strand to evaluate the effects of manufacturing parameters. Bamboo random strandboards were fabricated using phenol-formaldehyde resin with four dosage levels ranging from 4 to 10 percent, and five density levels ranging from 0.49 g/cm 3 to 0.81 g/cm . The mechanical properties and dimensional stability of bamboo strandboard were evaluated, and the results were summarized as follows. The bending properties and internal bond (IB) strength of the board increased with increasing density, showing a bilinear relation with an elbow at a density of 0.57 g/cm 3 , where the compaction ratio was approximately unity. Similar results were obtained in wet conditions. IB strength retention after the boil treatment remained almost constant, regardless of board density. The bending properties were slightly affected by resin content (RC). Although the IB strength increased with RC, IB strength seemed insufficient in comparison with that required for practical performance, which suggests that the glue blending technology needs to be improved. Thickness swelling (TS) decreased with increasing RC at each step of the wet-dry cyclic treatment. The TS of a board with 8 percent RC was approximately 7 percent after the treatment. Linear expansion per unit moisture content change (LE/MC) increased with increasing density from 0.016 %/% at 0.49 g/cm 3 to 0.023 %/% at 0.81 g/cm 3 , while the effect of RC on LE/MC was not remarkable in this range of RC.
Diameter Routing Message Priority (2016)

When making routing and resource allocation decisions, Diameter nodes
currently have no generic mechanism to determine the relative priority
of Diameter messages. This document addresses this by defining a
mechanism to allow Diameter endpoints to indicate the relative
priority of Diameter transactions. With this information, Diameter
nodes can factor that priority into routing, resource allocation, and
overload abatement decisions.
[Antisoporific and cardiotropic properties of new amino acid derivatives of nicotinic acid]. (1986)

On the models of urethane, nembutal and ethyl alcohol sleep it was shown that nicotinoylcapronate, nicotinoylserine and nicotinoylvaline possess antihypnotic properties being superior to those of cordiamine and on some models phenamine. Nicotinoylvaline and nicotinoylalanine normalized the myocardial contraction in animals with experimental ischemia.
Probing of the structural stability of vimentin and desmin-type intermediate filaments with Ca2+-activated proteinase, thrombin and lysine-specific endoproteinase Lys-C. (1987)

Intermediate filaments (IFs) reconstituted from purified, delipidated vimentin and desmin as well as respective protofilaments were subjected to degradation by Ca2+-activated neutral thiol proteinase, thrombin and lysine-specific endoproteinase Lys-C, respectively. The breakdown products were analyzed by SDS-polyacrylamide gel electrophoresis and negative stain electron microscopy. While Ca2+-activated proteinase and thrombin caused rapid and complete degradation of IFs with kinetics not significantly different from those of the degradation of protofilaments, lysine-specific endoproteinase did not exert any electron microscopically detectable effect on filament structure. Although both types of subunit proteins were truncated at their non-alpha-helical, C-terminal polypeptides by this proteinase, they were still able to assemble into 10 nm filaments. Closer electron microscopic inspection of IFs treated with Ca2+-activated proteinase revealed numerous ruptures along the filaments already at very early stages of digestion. SDS-polyacrylamide gel electrophoresis of the processed filaments in conjunction with previous biochemical characterizations of the breakdown of protofilaments by Ca2+-activated proteinase showed that these inhomogeneities primarily arose from degradation of the arginine-rich, non-alpha-helical N-termini of the filament proteins. These findings demonstrate that, although the N-terminus of vimentin and desmin is essential for filament stability, it is still highly susceptible to proteolytic attack in particular and very likely to posttranslational modification in general. Such structural modifications of the N-termini of IF proteins might exert great influences on the intracellular distribution and molecular organization of IFs in various physiological and pathological conditions.
NON-DESTRUCTIVE INVESTIGATION AND DAMAGE PREVENTION USING GROUND PENETRATING RADAR (2002)

Ground Penetrating Radar (GPR) systems, which transmit ultra-wideband pulses to map subsurface conditions nondestructively, have advanced significantly in the last decade. Due to innovations in technology such as improved analysis software, data generated by the systems is much easier to interpret and can be used in mainstream maintenance and inspection. The system is safe to use and does not interfere with users' communication systems. When employed in the public sector, the system can save both time and money. For instance, the GPR can map the subsurface conditions of highways, bridges, concrete structure and can be used for utility mapping.
Optical Voltage and Current Measuring System for Electric Power Systems (1986)

Recently, optical voltage and current measuring methods based on a principle different from that of the existing apparatus have been developed. As the most promising method among them, a voltage measuring method which uses an electrooptic effect called the Pockels effect and a current measuring method which uses a magnetooptic effect called the Faraday effect have been proposed. The authors have developed an optical voltage measuring system based on the electrooptic effect in bismuth germanium oxide Bi4Ge3O12 and a current measuring system based on the magnetooptic effect of borosilicate crown glass for the purpose of utilization in electric power systems. As a result of the development, high accurate voltage and current measuring systems such as non linearity error less than ±0.4% and temperature stability less than ±1.0% were obtained. Furthermore, short-circuit current was measured with the current measuring system, and an accuracy within 0 to -4% in the range of 30 kApeak to 150 kApeak was obtained. When the measuring systems were mounted on the model of 70 kV class gas insulated switchgears, it was verified that the measuring systems had satisfactory linearity and temperature stability.

From conceptual design to performance optimization of ETL workflows: current state of research and open problems (2017)

In this paper, we discuss the state of the art and current trends in designing and optimizing ETL workflows. We explain the existing techniques for: (1) constructing a conceptual and a logical model of an ETL workflow, (2) its corresponding physical implementation, and (3) its optimization, illustrated by examples. The discussed techniques are analyzed w.r.t. their advantages, disadvantages, and challenges in the context of metrics such as autonomous behavior, support for quality metrics, and support for ETL activities as user-defined functions. We draw conclusions on still open research and technological issues in the field of ETL. Finally, we propose a theoretical ETL framework for ETL optimization.

Analyzing the main trade-offs in multiobjective radiation therapy treatment planning databases (2009)

Multiobjective radiotherapy planning aims to capture all clinically relevant trade-offs between the various planning goals. This is accomplished by calculating a representative set of Pareto optimal solutions and storing them in a database. The structure of these representative Pareto sets is still not fully investigated. We propose two methods for a systematic analysis of multiobjective databases: principal component analysis and the isomap method. Both methods are able to extract the key trade-offs from a database and provide information which can lead to a better understanding of the clinical case and intensity-modulated radiation therapy planning in general.
A Framework for Filtering News and Managing Distributed Data. (1997)

: With the development and diffusion of the Internet worldwide connection, a large amount of information is available to the users. Methods of information filtering and fetching are then required. This paper presents two approaches. The first concerns the information filtering system ProFile based on an adaptation of the generalized probabilistic model of information retrieval. ProFile filters the netnews and uses a scale of 11 predefined values of relevance. ProFile allows the user to update on--line the profile and to check the discrepancy between the assessment and the prediction of relevance of the system. The second concerns ABIS, an intelligent agent for supporting users in filtering data from distributed and heterogeneous archives and repositories. ABIS minimizes user&apos;s effort in selecting the huge amount of available documents. The filtering engine memorizes both user preferences and past situations. ABIS compares documents with the past situations and finds the similarity scor...
