A Unifying Perspective on Context-Aware Evaluation and Management of Heterogeneous Wireless Connectivity (2010)

The growing market of wireless devices with multiple connectivity technologies, e.g., Wi-Fi, Bluetooth, and UMTS, is pushing toward the necessity of seamless autonomic selection of the proper connectivity network at any time. That selection should be context-dependent and consider several elements, at different abstraction layers, from bandwidth requirements to network congestion, from connectivity costs to user preferences. As a symptom of the recognized relevance of this topic, relevant research work has recently addressed context-dependent connectivity management. We claim the need to provide both practitioners and newcomers of this research field with a comprehensive survey with a unifying perspective, to better point out similarities and specific aspects of the numerous solutions in the literature. In particular, the paper aims to achieve the twofold goal of i) identifying the primary design choices, together with corresponding tradeoffs, emerging from recent proposals, and ii) better positioning the wide variety of related work based on a single classification scheme. To that purpose, we introduce an original model to represent solution architectures, by showing how it makes the adopted design choices manifest and facilitates the positioning of proposed approaches, e.g., by throwing new light on the usage of 4th Generation and Always Best Connected terms. In addition, based on that model, we propose a novel taxonomy to cluster the proposals in the field along three first-level classification directions: management scope, evaluation process, and continuity management. A wide set of examples illustrate how our taxonomy is useful to thoroughly understand the differences and similarities among state-of-the-art solutions in the literature, to some extent independently on technology-specific implementation details, thus providing a valuable classification tool also for future proposals.
An all-sharing load balancing protocol in distributed systems on the CSMA/CD local area network (2003)

A protocol for dynamic load balancing in distributed systems on the CSMA/CD local area network is presented. Using the protocol, the workload is evenly distributed throughout the system when load-balancing activity is triggered, and effective load distribution is accomplished through transmission of load-balancing messages in a collision-free manner. Analytical and simulation results are presented to show the efficiency of the protocol.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Influence of chemical and phase composition of mineral admixtures on their pozzolanic activity (2002)

The influence of the chemical and phase composition of different mineral admixtures on pozzolanic activity was studied. Local kaolin clay, activated kaolin clay, porcellanite, activated porcellanite, pumice, fly ash, silica fume and ground quartz were used as components of blended binders for various mortars. Thermal treatments were performed as a means for activation of the minerals. The phase transformations during heat treatment were studied by X-ray diffraction services (XRD) and differential thermal analysis/thermogravimetric analyses (DTA/TGA). The pozzolanic activity of these materials as a function of heat treatment parameters was investigated.
Soluble CD26/30 levels before and after treatment with interferon-alpha and ribavirin combination therapy in a pediatric hepatitis C patient. (2004)

Chronic hepatitis C virus (HCV) infection frequently leads to end-stage liver diseases and extrahepatic complications. Combination therapy with interferon-alpha (IFN-alpha) and ribavirin is now recommended as the first-line therapy for patients with chronic hepatitis C in adults. However, the benefit of such combination therapy in children with hepatitis C is still under investigation. We report here on a 6-year-old boy admitted with chronic active hepatitis C infection and treated with interferon-alpha and ribavirin. After treatment for 12 months, his serum showed negative HCV RNA, and normal alanine aminotransferase, and there was a sustained response. The patient's serum soluble CD30 (sCD30) level was higher than that of controls (>100 U/mL vs 46 +/- 11 U/mL) before combination therapy but there was no difference in soluble CD26 (sCD26) [103 ng/mL vs 119 +/- 28 ng/mL]. The sCD30 decreased and sCD26 increased at 6 months (45 U/mL and 188.3 ng/mL, respectively) using combined therapy as well as at 4 months after discontinuing it (33 U/mL and 167.8 ng/mL, respectively) in our patient. The results indicate that combined treatment with IFN-alpha and ribavirin may be used as the first-line treatment for children with chronic hepatitis C. The changes of sCD30 and sCD26 may be helpful in estimating of HCV infection activity.
Avoidance of doxorubicin resistance in osteosarcoma cells using a new quinoline derivative, MS-209. (1998)

P-glycoprotein (Pgp), a membrane drug efflux pump, is thought to be responsible for the observed drug resistance in osteosarcoma. We have recently developed Pgp-positive, multidrug resistant (MDR) murine osteosarcoma cell lines, which may be suitable models for the study of drug resistance in osteosarcoma. In this study, we investigated the effect of a newly synthesized quinoline compound, MS-209, on the reversal of doxorubicin (DOX) resistance in these cell lines. Three different types of resistance modifying agents (RMAs) as well as MS-209 were studied. These included the calcium channel blocker verapamil, and the immunosuppressive agents cyclosporin A and FK506. The reversal effects of the RMAs on DOX resistance were assessed by the MTT assay. In the absence of RMAs, the MDR osteosarcoma cells were 20-fold more resistant to DOX than the parental cells. When MS-209 was added at a final concentration of 0.1 to 3 microM to the MDR cells, 3-to 74-fold sensitization was observed. A complete reversal (37-fold sensitization) of the resistance was obtained at 1 microM MS-209. This concentration of MS-209 was 3-, 8- and 28-fold more effective than the same concentration of FK506, verapamil and cyclosporin A, respectively. These results indicate that MS-209 may be a more effective RMA, and that DOX resistance in osteosarcoma cells could be reversed by comparatively low doses of MS-209.
A subnanosecond Josephson 16-bit ALU (1988)

The design and characteristics of a Nb based Josephson 16-bit arithmetic logic unit (ALU) for use as a major component of a practical Josephson microprocessor are discussed. The ALU has 900 gates and uses dual-rail logic to perform 12 functions. One of the simplest algorithms, the ripple-carry method, is used. Experiments confirmed that ALU functions operated correctly. The critical path delay time was 860 ps for a 10.1-mW power dissipation. Average values estimated from experiments are 9.2 ps for the gate delay and 113 mu W for the gate power dissipation. The results demonstrate that development of a Josephson microprocessor is feasible.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Heterojunction diodes formed using thin-film C containing polycrystalline diamond and Si (1990)

Diodelike I-V characteristics measured in Al/C/Si structures formed by depositing thin C films onto Si substrates from a CH/sub 4//Ar plasma are discussed. The films, which contain polycrystalline diamond grains, are 500-1000 A thick. It is shown that the true I-V characteristics can be measured only after removing the fixed interface charge at the metal-C interface. By taking the C to be an intrinsic polycrystalline semiconductor, it is possible to treat the diode characteristics as arising from the presence of a C/Si heterojunction.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Experimental and Systems Studies of the Alkali Metal Thermoelectric Converter for Aerospace Power (1983)

The alkali metal thermoelectric converter (AMTEC) is a thermally regenerative electrochemical device for the direct conversion of heat to electrical energy. It is characterized by high potential efficiencies and no moving parts, which makes it a candidate for space power applications. This paper presents a review of AMTEC operating principles and characteristics showing that device conversion efficiencies of 15-40% may be achievable. Experimental voltage vs current curves are presented where power densities of 0.7 W/cm are observed. Measured electrode efficiencies of up to 40% that confirm the high potential efficiencies of the AMTEC are presented. Also shown are the results of preliminary radiation heat-transfer measurements, data that can be utilized to study methods for reducing parasitic radiation losses in the AMTEC. Finally, the results of a preliminary design study are presented showing that by incorporating the AMTEC into existing space power system designs, conversion efficiencies of 15-20% may be achieved at specific powers of 14-17 We/kg in a small power system (800 W). Similar performance is also predicted for a much larger («360 kW) nuclear electric system.

Effect of AlN nucleation layer growth conditions on buffer leakage in AlGaN∕GaN high electron mobility transistors grown by molecular beam epitaxy (MBE) (2005)

The effect of the AlN nucleation layer growth conditions on buffer leakage in unintentionally doped AlGaN∕GaN high electron mobility transistors was investigated. The samples were grown by rf-plasma assisted molecular beam epitaxy on 4H–SiC (0001). Drain-source leakage currents were found to be markedly different for samples grown with different Al∕N flux ratios during the AlN nucleation layer. Growth of N-rich nucleation layers (Al∕N&lt;1) resulted in a significant reduction in buffer leakage. Secondary ion mass spectroscopy results showed that Si incorporation into Al-rich AlN layers (Al∕N&gt;1) grown on SiC was as high as ∼1–2×1018atoms∕cm3. In contrast, Si incorporation into N-rich AlN layers was two orders of magnitude lower, ∼2×1016atoms∕cm3. Initial devices grown on low-leakage material realized via N-rich nucleation yielded output power densities at 4GHz of 4.8W∕mm with a power added efficiency (PAE) of 62% at a drain bias of 30V, and 8.1W∕mm with a PAE of 38% at a drain bias of 50V.
Precise calling context encoding (2010)

Calling contexts are very important for a wide range of applications such as profiling, debugging, and event logging. Most applications perform expensive stack walking to recover contexts. The resulting contexts are often explicitly represented as a sequence of call sites and hence bulky. We propose a technique to encode the current calling context of any point during an execution. In particular, an acyclic call path is encoded into one number through only integer additions. Recursive call paths are divided into acyclic subsequences and encoded independently. We leverage stack depth in a safe way to optimize encoding: if a calling context can be safely and uniquely identified by its stack depth, we do not perform encoding. We propose an algorithm to seamlessly fuse encoding and stack depth based identification. The algorithm is safe because different contexts are guaranteed to have different IDs. It also ensures contexts can be faithfully decoded. Our experiments show that our technique incurs negligible overhead (1.89% on average). For most medium-sized programs, it can encode all contexts with just one number. For large programs, we are able to encode most calling contexts to a few numbers.

General synthetic route to benz[<i>g</i>]isoquinolines (2‐azaanthracenes) (1998)

Abstract Benzylic zinc reagents add with high regioselectivity to 1‐(phenoxycarbonyl) salts derived from pyridine‐3‐carboxaldehyde ( 1a ) or 3‐acetylpyridine ( 1b ) to yield 1‐(phenoxylcarbonyl)‐4‐benzyl‐1,4‐dihydropyridine‐3‐carboxaldehydes 5a, 5c or ketones 5b, 5d . Aromatizations of these dihydro analogues with sulfur led to the corresponding aldehydes 6a, 6c or ketones 6b, 6d . An alternate synthesis to the aldehydic precursors involved additions of benzylic zinc reagents to 1‐(phenoxycarbonyl) salts formed from methyl nicotinates which led to the corresponding methyl 1‐(phenoxycarbonyl)‐4‐benzyl‐1,4‐dihydronicotinates 7a, 7b . Aromatizations of 7a, 7b led to the corresponding pyridine esters 8a, 8b which on reduction with lithium aluminum hydride yielded the corresponding carbinols 9a, 9b . Oxidation of 9a, 9b by manganese dioxide afforded aldehydes 6e, 6f . Aldehydes 6a‐f were readily converted into the benz[ g ]isoquinolines 10a‐f on heating in polyphosphoric acid.
Influence of Elevated Temperatures and Cooling Method on the Microstructure Development and Phase Evolution of Alkali-Activated Slag (2022)

The performance of alkali-activated slag (AAS) under thermal treatment has received particular attention. In this study, the effect of five elevated temperatures (25, 200, 400, 600, and 800 °C) and two cooling methods (air cooling and water spraying) on the mechanical and durability properties, microstructure, and phase evolution of AAS was investigated. The results show that AAS mortars exhibit higher resistance to thermal attack than OPC in terms of strength and durability. AAS samples cooled in air show higher residual strength than those cooled by spraying water, which is mainly attributed to fewer cracks formed in the former. The resistance to carbonization of exposed AAS mortars depends on the pore size distribution, while that to chloride ion penetration depends on the porosity. Cooling methods show a minor effect on the phase evolution of reaction products, suggesting that the microstructure degradation is mainly responsible for the damage of AAS structures. This study provides fundamental knowledge for the thermally induced changes on AAS which contributes new ideas for the development of construction structures with higher fire resistance.

Graphene electrodes for electric poling of electro-optic polymer films (2020)

We propose electric poling of electro-optic (EO) polymer films with graphene electrodes. The use of graphene electrodes can waive the use of buffer layers and minimize the poling voltage. To demonstrate the idea, we prepared EO polymer thin-film waveguides for poling with traditional Au/ITO electrodes and graphene electrodes, where the EO polymer is a guest-host system formed by doping 15 wt% of dipolar polyene chromophore AJLZ53 into the random copolymer P(S-co-MMA). Our experiments confirm that the use of graphene electrodes can significantly reduce the poling voltage. For a 3.8-µm-thick EO polymer film, we achieve high EO coefficients of 82 pm/V at 1541 nm and 110 pm/V at 1300 nm with a poling voltage of 420 V. In addition, the use of graphene electrodes allows more flexible waveguide designs and can potentially simplify the fabrication of devices based on EO polymer.

Analysis and synthesis equations for edge-coupled suspended substrate microstrip line (2003)

The dispersion characteristics of the edge-coupled suspended substrate microstrip line are analyzed by the method of lines. On the basis of numerical results obtained, a set of closed-form analysis and synthesis equations, valid over a practical application range of structural parameters and substrate dielectric constant, is obtained. Compared with the data obtained from SUPERCOMPACT, the accuracy is found to be within 3.5% for analysis and 5% for synthesis. It is concluded that the computer-aided design of edge-coupled suspended substrate microstrip lines can be carried out easily using these equations.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
A Comparison of Polymer Flooding With In-Depth Profile Modification (2011)

Abstract For stratified reservoirs with free crossflow and where fractures do not cause severe channeling, improved sweep is often needed after water breakthrough. For moderately viscous oils, polymer flooding is an option for this type of reservoir. However, in recent years, an in-depth profile modification method had been commercialized where a block is placed in the high-permeability zone(s). This sophisticated idea requires (1) the blocking agent must have a low viscosity (ideally a unit-mobility displacement) during placement, (2) the rear of the blocking-agent bank in the high-permeability zone(s) must outrun the front of the blocking-agent bank in adjacent less-permeable zones, and (3) an effective block to flow must form at the appropriate location in the high-permeability zone(s). Achieving these objectives is challenging but has been accomplished in at least one field test. This paper asks: When is this in-depth profile modification process a superior choice over conventional polymer flooding? Using simulation and analytical studies, we examined oil recovery efficiency for the two processes as a function of (1) permeability contrast, (2) relative zone thickness, (3) oil viscosity, (4) polymer solution viscosity, (5) polymer or blockingagent bank size, and (5) relative costs for polymer versus blocking agent. The results reveal that in-depth profile modification is most appropriate for high permeability contrasts (e.g. 10:1), high thickness ratios (e.g., less-permeable zones being 10 times thicker than high-permeability zones), and relatively low oil viscosities. Because of the high cost of the blocking agent (relative to conventional polymers), economics favor small blocking-agent bank sizes (e.g. 5% of the pore volume in the high-permeability layer). Even though short-term economics may favor in-depth profile modification, ultimate recovery may be considerably less than from a traditional polymer flood.

Complex eye movement pattern biometrics: Analyzing fixations and saccades (2013)

This paper presents an objective evaluation of previously unexplored biometric techniques utilizing patterns identifiable in human eye movements to distinguish individuals. The distribution of primitive eye movement features are compared between eye movement recordings using algorithms based on the following statistical tests: the Ansari-Bradley test, the Mann-Whitney U-test, the two-sample Kolmogorov-Smirnov test, the two-sample t-test, and the two-sample Cramer-von Mises test. Score-level information fusion is applied and evaluated by: weighted mean, support vector machine, random forest, and likelihood ratio. The accuracy of each comparison/jusion algorithm is evaluated, with results suggesting that, on high resolution eye tracking equipment, it is possible to obtain equal error rates of 16.5% and rank-1 identification rates of 82.6% using the two-sample Cramér-von Mises test and score-level information fusion by random forest, the highest accuracy results on the considered dataset.
