Concurrency Control in Advanced Database Applications

Concurrency control has been thoroughly studied in the context of traditional database applications such as banking and airline reservations systems. There are relatively few studies, however, that address the concurrency control issues of advanced database applications such as CAD/CAM and software development environments. The concurrency control requirements in such applications are different from those in conventional database applications; in particular, there is a need to support non-serializable cooperation among users whose transactions are long-lived and interactive, and to integrate concurrency control mechanisms with version and configuration control. This paper outlines the characteristics of data and operations in some advanced database applications, discusses their concurrency control requirements, and surveys the mechanisms proposed to address these requirements.
Human-enabled sustainable management of mobile cloud on 5G network: student research abstract

This paper presents a hierarchical system architecture for Mobile Cloud Computing based on a novel 5G system architecture. Initially, a hierarchical system architecture is divided into three phases, i.e., foglet layer, service layer, and communication layer. Foglet layers provide the functionality of efficient resource sharing, the service layers assist the network by providing cloud services, and finally, the communication layers help in providing energy efficient communication using 5G system architecture. Simulation results show that the proposed scheme outperforms the existing cloud computing example scenario regarding cost and time.1
A longitudinal twin study of fears from middle childhood to early adulthood: evidence for a developmentally dynamic genome.

CONTEXT
While the nature of common fears changes over development, we do not know whether genetic effects on fear-proneness are developmentally stable or developmentally dynamic.


OBJECTIVE
To determine the temporal pattern of genetic and environmental effects on the level of intensity of common fears.


DESIGN
Prospective, 4-wave longitudinal twin study. Structural modeling was performed with Mx.


SETTING
General community.


PARTICIPANTS
Two thousand four hundred ninety twins and their parents from the Swedish Twin Study of Child and Adolescent Development.


MAIN OUTCOME MEASURE
The level of parent- and/or self-reported fears obtained at ages 8 to 9, 13 to 14, 16 to 17, and 19 to 20 years.


RESULTS
Thirteen questionnaire items formed 3 distinct fear factors: situational, animal, and blood/injury. For all 3 fears, the best-fit model revealed developmentally dynamic effects and, in particular, evidence for both genetic attenuation and innovation. That is, genetic factors influencing fear intensity at age 8 to 9 years decline substantially in importance over time. Furthermore, new sets of genetic risk factors impacting fear intensity "come on line" in early adolescence, late adolescence, and early adulthood. As the twins aged, the influence of the shared environment declined and unique environment increased. No sex effects were found for situational fears while for animal and blood/injury fears, genetic factors in males and females were correlated but not identical. Shared environmental factors were both more important and more stable for animal fears than for situational or blood/injury fears.


CONCLUSIONS
Genetic effects on fear are developmentally dynamic from middle childhood to young adulthood. As children age, familial-environmental influences on fears decline in importance.
Stereo-Assist: Top-down stereo for driver assistance systems

This paper presents a top-down approach to stereo for use in driver assistance systems. We introduce an asymmetric configuration where monocular object detection and range estimation is performed in the primary camera and then that image patch is aligned and matched in the secondary camera. The stereo distance measure from the matching assists in target verification and improved distance measurements. This approach, Stereo-Assist, shows significant advantages over the classical bottom-up stereo approach which relies on first computing a dense depth map and then using the depth map for object detection. The new approach can provide increased object detection range, reduced computational load, greater flexibility in camera configurations (we are no longer limited to side-by-side stereo configurations), greater robustness to obstructions in part of the image and mixed camera modalities FIR/VIS can be used. We show results with two novel configurations and illustrate how monocular object detection allows for simple online calibration of the stereo rig.

Transient Electrothermal Simulation of Power Semiconductor Devices

In this paper, a new thermal model based on the Fourier series solution of heat conduction equation has been introduced in detail. 1-D and 2-D Fourier series thermal models have been programmed in MATLAB/Simulink. Compared with the traditional finite-difference thermal model and equivalent RC thermal network, the new thermal model can provide high simulation speed with high accuracy, which has been proved to be more favorable in dynamic thermal characterization on power semiconductor switches. The complete electrothermal simulation models of insulated gate bipolar transistor (IGBT) and power diodes under inductive load switching condition have been successfully implemented in MATLAB/Simulink. The experimental results on IGBT and power diodes with clamped inductive load switching tests have verified the new electrothermal simulation model. The advantage of Fourier series thermal model over widely used equivalent RC thermal network in dynamic thermal characterization has also been validated by the measured junction temperature.
Tax-benefit revealed social preferences

This paper inverts the usual logic of applied optimal income taxation. It starts from the observed distribution of income before and after redistribution and corresponding marginal tax rates. Under a set of simplifying assumptions, it is then possible to recover the social welfare function that would make the observed marginal tax rate schedule optimal. In this framework, the issue of the optimality of an existing tax-benefit system is transformed into the issue of the shape of the social welfare function associated with that system and whether it satisfies elementary properties. This method is applied to the French redistribution system with the interesting implication that the French redistribution authority may appear, under some plausible scenario concerning the size of the labor supply behavioral reactions, non Paretian (e.g. giving negative marginal social weights to the richest class of tax payers).

The need for and meaning of positive organizational behavior

This essay draws from the emerging positive psychology movement and the author’s recent articles on the need for and meaning of a positive approach to organizational behavior. Specifically, the argument is made that at this time, the OB field needs a proactive, positive approach emphasizing strengths, rather than continuing in the downward spiral of negativity trying to fix weaknesses. However, to avoid the surface positivity represented by the non-sustainable best-sellers, the case is made for positive organizational behavior (POB) to take advantage of the OB field’s strength of being theory and research driven. Additional criteria for this version of POB are to identify unique, state-like psychological capacities that can not only be validly measured, but also be open to development and performance management. Confidence, hope, and resiliency are offered as meeting such POB inclusion criteria. The overall intent of the essay is to generate some positive thinking and excitement for the OB field and ‘hopefully’ stimulate some new theory building, research, and effective application.
Coupling of simulators for the investigation of car-to-x communication aspects

Accompanied by the continuous progression of the maturity of car-to-x communication protocols and corresponding system architectures, the need for integrated network simulation approaches which consider realistic channel modeling on the one hand and appropriate mobility models on the other hand becomes more and more observable. Moreover, in order to analyze the impacts of car-to-x applications on the behavior of vehicles, an interconnection of different simulation tools is needed. In this paper, a concept for the interconnection of network, channel and road traffic simulations is presented. This concept relies on network simulation based on the open source simulator OMNeT++ and the INET Framework, which utilizes a coupling to the well-known road traffic simulator SUMO. In order to characterize the radio channel, an interconnection between OMNeT++ and a ray optical propagation model is being established. Furthermore, some preliminary simulation results are presented which serve as a proof of concept.
Adventitious shoot regeneration in cultures of Humulus lupulus L. (hop) cvs. Brewers Gold and Nugget

 A very efficient protocol for plant regeneration from two commercial Humulus lupulus L. (hop) cultivars, Brewers Gold and Nugget has been established, and the morphogenetic potential of explants cultured on Adams modified medium supplemented with several concentrations of cytokinins and auxins studied. Zeatin at 4.56 μm produced direct caulogenesis and caulogenic calli in both cultivars. Subculture of these calli on Adams modified medium supplemented with benzylaminopurine (4.4 μm) and indolebutyric acid (0.49 μm) promoted shoot regeneration which gradually increased up to the third subculture. Regeneration rates of 60 and 29% were achieved for Nugget and Brewers Gold, respectively. By selection of callus lines, it has been possible to maintain caulogenic potential for 14 months. Regenerated plants were successfully transferred to field conditions.
New indirect immunofluorescence assay as a confirmatory test for human immunodeficiency virus type 1.

BACKGROUND
Screening of blood and blood products for human immunodeficiency virus (HIV) is routinely performed using the enzyme-linked immunosorbent assay (ELISA), and the results confirmed by Western blot (WB). However, western blot is expensive and mostly performed in developed countries. A technique more superior or comparable to WB and adaptable to developing countries must be sought. In an effort to identify such a technique, this study determined the efficiency of indirect immunofluorescence assay (IFA) to detect antibodies to HIV-1.


OBJECTIVE
To determine the accuracy and sensitivity of an in-house immunofluorescence assay (IFA) to detect antibodies to HIV-1 in plasma.


DESIGN
A comparative study to evaluate the performance of indirect immunofluorescence assay (IFA) and western blot (WB) techniques in the detection of antibodies to HIV-1.


SETTING
Kenya Medical Research Institute, Centre for Virus Research. The study was conducted between June and December 2001.


METHODS
The evaluation of IFA as a technique for detecting antibodies to HIV-1 utilized a total of 400 samples. For these samples, IFA was compared with ELISA and particle agglutination (PA) (manuscript under preparation). Of the 400 samples, there were discrepant results in the three assays in only 36 samples. IFA was compared with Western blot (WB) to confirm the true HIV-1 serostatus in these 36 plasma specimens. The IFA technique used acetone-fixed HIV-1 infected MOLT-4 cells in one spot on a Teflon coated slide and uninfected MOLT-4 cells alone in a second spot to asses non-specific fluorescence. Western blot was performed according to the instructions of the manufacturer.


RESULTS
The sensitivity and specificity of IFA based on 36 plasma specimens tested was 71.4% and 100% respectively. All samples that were HIV seronegative by WB were also HIV seronegative by IFA. However, two (5.6%) samples were HIV seronegative by IFA but seropositive by WB.


CONCLUSION
The data obtained show that IFA can be used as a primary confirmatory test in Kenya.
Innovation Ecosystems and the Pace of Substitution: Re-Examining Technology S-Curves

Why do some new technologies emerge and quickly supplant incumbent technologies while others take years or decades to take off? We explore this question by presenting a framework that considers both the focal competing technologies as well as the ecosystems in which they are embedded. Within our framework, each episode of technology transition is characterized by the ecosystem emergence challenge that confronts the new technology and the ecosystem extension opportunity that is available to the old technology. We identify four qualitatively distinct regimes with clear predictions for the pace of substitution. Evidence from 10 episodes of technology transitions in the semiconductor lithography equipment industry from 1972 to 2009 offers strong support for our framework. We discuss the implication of our approach for firm strategy.

Evolution of nanoporosity in dealloying

Dealloying is a common corrosion process during which an alloy is ‘parted’ by the selective dissolution of the most electrochemically active of its elements. This process results in the formation of a nanoporous sponge composed almost entirely of the more noble alloy constituents. Although considerable attention has been devoted to the morphological aspects of the dealloying process, its underlying physical mechanism has remained unclear. Here we propose a continuum model that is fully consistent with experiments and theoretical simulations of alloy dissolution, and demonstrate that nanoporosity in metals is due to an intrinsic dynamical pattern formation process. That is, pores form because the more noble atoms are chemically driven to aggregate into two-dimensional clusters by a phase separation process (spinodal decomposition) at the solid–electrolyte interface, and the surface area continuously increases owing to etching. Together, these processes evolve porosity with a characteristic length scale predicted by our continuum model. We expect that chemically tailored nanoporous gold made by dealloying Ag-Au should be suitable for sensor applications, particularly in a biomaterials context.
Extensive Imitation is Irrational and Harmful ∗

Rationality leads people to imitate those with similar tastes but different information. But people who imitate common sources develop correlated beliefs, and rationality demands that later social learners take this redundancy into account. This implies severe limits to rational imitation. We show that (i) in most natural observation structures besides the canonical single-file case, full rationality dictates that people must “anti-imitate” some of those they observe; and (ii) in every observation structure full rationality dictates that people who do not anti-imitate can, in essence, imitate at most one person among predecessors who share common information. We also show that in a very broad class of settings, virtually any learning rule in which people regularly do imitate more than one person without anti-imitating others will lead to a positive (and, in some environments, arbitrarily high) probability of people converging to confident and wrong long-run beliefs. When testing either the rationality or the efficiency of social learning, researchers should not focus on whether people follow others’ behavior—but instead whether they follow it too much.

The Impact of Common Currencies on Financial Markets: A Literature Review and Evidence from the Euro Area

This paper reviews both the theoretical and empirical literature on the impact of common currencies on financial markets and evaluates the first three years of experience with Economic and Monetary Union (EMU). If we assume that multiple currencies prevent national financial markets from integrating, a currency union can improve welfare by (i) encouraging international risk diversion through private portfolio diversification, and (ii) improving growth performance by allowing for riskier, higher-quality, more long-run investment. EMU has encouraged integration among the still fairly fragmented European financial markets both directly and indirectly. When applying the European experience to a potential North American monetary union, one should consider that the U.S. and Canadian financial markets are already more integrated than the European ones, and thus the potential gains in terms of greater financial market integration from a common currency in North America may be more moderate than in Europe.

Comparison of Sum Absolute QRST Integral, and Temporal Variability in Depolarization and Repolarization, Measured by Dynamic Vectorcardiography Approach, in Healthy Men and Women

BACKGROUND
Recently we showed the predictive value of sum absolute QRST integral (SAI QRST) and repolarization lability for risk stratification of sudden cardiac death (SCD) in heart failure patients. The goal of this study was to compare SAI QRST and metrics of depolarization and repolarization variability in healthy men and women.


METHODS
Orthogonal ECGs were recorded at rest for 10 minutes in 160 healthy men and women (mean age 39.6±14.6, 80 men). Mean spatial TT' angle, and normalized variances of T loop area, of spatial T vector amplitude, of QT interval and Tpeak-Tend area were measured for assessment of repolarization lability. Normalized variances of spatial QRS vector and QRS loop area characterized variability of depolarization. In addition, variability indices (VI) were calculated to adjust for normalized heart rate variance. SAI QRST was measured as the averaged arithmetic sum of areas under the QRST curve.


RESULTS
Men were characterized by shorter QTc (430.3±21.7 vs. 444.7±22.2 ms; P<0.0001) and larger SAI QRST (282.1±66.7 vs. 204.9±58.5 mV*ms; P<0.0001). Repolarization lability negatively correlated with spatial T vector amplitude. Adjusted by normalized heart rate variance, QT variability index was significantly higher in women than in men (-1.54±0.38 vs. -1.70±0.33; P = 0.017). However, in multivariate logistic regression after adjustment for body surface area, QTc, and spatial T vector amplitude, healthy men had 1.5-3 fold higher probability of having larger repolarization lability, as compared to healthy women (T vector amplitude variability index odds ratio 3.88 (95%CI 1.4-11.1; P = 0.012).


CONCLUSIONS
Healthy men more likely than women have larger repolarization lability.
Meso and microscale clad interface characteristics of hot-rolled stainless steel clad plate

Abstract Stainless steel clad plate containing corrosion-resistant 304 stainless steel cladding and Q235 carbon steel substrate has been successfully fabricated by vacuum hot rolling at 1150 °C. The interface characteristics, microstructure, alloy element distribution and precipitation phases of clad plate were investigated by SEM, EPMA and TEM analysis in detail. Due to the carbon element diffusion, a decarburized layer (60–80 μm) and a carburized layer (20–40 μm) were formed at the carbon steel substrate and stainless steel cladding beside the interface, respectively. The uphill diffusion and interface peak value of carbon element are attributed to the differences in the diffusion velocity and solubility of carbon element in the substrate and cladding. Concentration gradient and diffusion coefficient between Cr and Ni elements are different, leading to different diffusion distances. Meanwhile, the grain boundaries of carburized layer were surrounded by Cr 23 C 6 particles. The interface with a thickness of 300–400 nm contains refined grains accompanying with many Cr 23 C 6 and MnSi 2 O 4 , SiO 2 particles. The sufficient alloy element diffusion behavior and interface oxides, precipitation phases lead to a high interface bonding shear strength (389 MPa).

Connections between high energy QCD and statistical physics

It has been proposed that the energy evolution of QCD amplitudes in the high-energy regime falls in the universality class of reaction-diffusion processes. We review the arguments for this correspondence, and we explain how it enables one to compute analytically asymptotic features of QCD amplitudes.
