Dynamic voltage and frequency scaling for optimal real-time scheduling on multiprocessors

Not only system performance but also energy efficiency is critically important for embedded systems. Optimal real-time scheduling is effective to not only schedulability improvement but also energy efficiency for the systems. In this paper, real-time dynamic voltage and frequency scaling (RT DVFS) techniques based on the theoretically optimal real-time static voltage and frequency scaling (RTSVFS) techniques proposed in our previous work are presented for multiprocessor systems. Simulation results show that RT-DVFS covers up the disadvantages of RT-SVFS in the sense that RTDVFS are not practically affected by the difference among systems, whereas the energy consumption of RT-SVFS highly depends on the selectable processor frequency especially in high system utilization.
SEASONAL CHANGES IN LEAF GAS EXCHANGE PARAMETERS IN PLATANUS ACERIFOLIA WILLD . AND ACER PSEUDOPLATANUS L . SEEDLINGS ON UNDEVELOPED ALLUVIAL SOIL ( FLUVISOL )

Seasonal changes of net photosynthesis (A), stomatal conductance (gs) and transpiration (E) were researched in Platanus acerifolia Willd. and Acer pseudoplatanus L. Measurements were carried out four times during vegetation period (July 16, August 20, September 5 and September 22) 2011 at seedling age 2+1, cultivated in the nursery. Soil in the nursery belongs to the type of undeveloped alluvial soil (fluvisol), sandy loam form, with the dominant fraction of fine sand (63.5%) and silt+clay fraction in a lower concentration (34.7%). A sharp reduction in net photosynthesis was observed in the second part of August and at the beginning of September, when both species exhibited their lowest net CO2 assimilation. Minimum A was 7.27 and 7.0 μmol m-2 s-1 in P. acerifolia and A. pseudoplatanus, respectively. Stomatal conductance followed rise-and-fall pattern of net photosynthesis during the entire period of observation. The seasonal course of transpiration was similar in P. acerifolia and A. pseudoplatanus, with a peak at the beginning of September. Maximum transpiration rate was 2.87 and 3.62 mmol m-2 s-1 in P. acerifolia and A. pseudoplatanus, respectively. Statistically signicant correlation between net photosynthesis and stomatal conductance, in both species, suggests that stomatal closure was the main factor controlling CO2 assimilation. Incomplete recovery of stomatal conductance and net photosynthesis in A. pseudoplatanus, after the rainfall at the end of September, suggests remaining stomatal limitations. Inferiority of A. pseudoplatanus was probably related to the sensitivity of this species to summer heat and drought owing to the fact that this species is native for sites determined by large share of silt in the soil texture and high content of moisture and nutrients in the soil.
Generalized Wavefunctions for Correlated Quantum Oscillators III: Chaos, Irreversibility.

In this third of a series of four articles, we continue the study of the representations of the dynamical transformations of systems of correlated quantized oscillators. By including generalized wave function solutions to Schrodinger's equation (belonging to a rigged Hilbert space), and by considering the algebra of observables as a whole, the presence of Devaney chaos, hyperbolic quasi-invariant measures, torus actions, ergodicity and entropy generation associ- ated to the non-invertible decay of Gamow vectors and their asso- ciated to Breit-Wigner resonances is shown. A weak (local) form of the second law of thermodynamics is demonstrated through the decay of resonances. Both coherence formation and decoherence (decay) are associated with irreversibility and may be associated with entropy growth, which is due to the dynamical time evolution of resonances. Hilbert space is the manifold of stationary states. There is a fractal structure associated with dynamical time evo- lution of resonances in the space of generalized states, and the statistical nature of the exponential decay may be identied with quasi-trapping. Equilibrium states may be regarded as strange at- tractors with respect to dynamical time evolution.
Posterior reversible encephalopathy syndrome: prognostic utility of quantitative diffusion-weighted MR images.

BACKGROUND AND PURPOSE The recently described posterior reversible encephalopathy syndrome (PRES) classically consists of reversible vasogenic edema in the posterior circulation territories, although conversion to irreversible cytotoxic edema has been described. We hypothesized that the extent of edema has prognostic implications and that diffusion-weighted MR imaging (DWI) can help predict the progression to infarction. METHODS Twenty-two patients with PRES and 18 control subjects were examined with isotropic DWI. Nineteen regions of interest (ROIs) were systematically placed, and apparent diffusion coefficients (ADCs) were computed and correlated with T2 and DWI signal intensity in each ROI. RESULTS T2 signal abnormalities were always present in territories of the posterior circulation. Anterior circulation structures were involved in 91% of patients. ADC values in areas of abnormal T2 signal were high. More extensive T2 signal abnormalities were seen in patients with a poor outcome than in patients who recovered. In six patients (27%), areas of high DWI signal intensity were seen with ADC values that were paradoxically normal, which we called pseudonormalized. Abnormal T2 signal intensity and high ADC values surrounded these areas. Follow-up images in two patients showed progression to infarction in pseudonormalized regions. CONCLUSION Vasogenic edema in PRES involves predominantly the posterior circulation territories, but anterior circulation structures are also frequently involved. The extent of combined T2 and DWI signal abnormalities correlate with patient outcome. High DWI signal intensity and pseudonormalized ADC values are associated with cerebral infarction and may represent the earliest sign of nonreversibility as severe vasogenic edema progresses to cytotoxic edema.
STRUCTURAL PROPERTIES OF ULTRA-COMPACT DWARF GALAXIES IN THE FORNAX AND VIRGO CLUSTERS

We present a detailed analysis of high-resolution two-band Hubble Space Telescope Advanced Camera for Surveys imaging of 21 ultra-compact dwarf (UCD) galaxies in the Virgo and Fornax Clusters. The aim of this work is to test two formation hypotheses for UCDs—whether they are bright globular clusters (GCs) or stripped (“threshed”) early-type dwarf galaxies—by direct comparison of UCD structural parameters and colors with GCs and galaxy nuclei. We find that the UCD surface brightness profiles can be described by a range of models and that the luminous UCDs in particular cannot be described by standard King models with tidal cutoffs as they have extended outer halos. This is not expected from traditional King models of GCs, but is consistent with recent results for massive GCs. The total luminosities, colors, and sizes of the UCDs (their position in the color–magnitude and luminosity–size diagrams) are consistent with them being either luminous GCs or threshed nuclei of both early-type and late-type galaxies (not just early-type dwarfs). For the most luminous UCDs we estimate color gradients over a limited range of radius. These are systematically positive in the sense of getting redder outward: mean Δ(F606W − F814W) = 0.14 mag per 100 pc with rms = 0.06 mag per 100 pc. The positive gradients found in the bright UCDs are consistent with them being either bright GCs or threshed early-type dwarf galaxies (except VUCD3). In contrast to the above results we find a very significant (>99.9% significance) difference in the sizes of UCDs and early-type galaxy nuclei: the effective radii of UCDs are 2.2+0.2−0.1 times larger than those of early-type galaxy nuclei at the same luminosity. This result suggests that an important test can be made of the threshing hypothesis by simulating the process and predicting what size increase is expected.
Exploration of Wisdom Ages: Firm survival

Studies confirm a tendency where elder individuals are more prone to become entre¬preneurs. Their motives are numerous ranging from feeling social included to maintain the same income level. Interesting as such, this paper contributes to the existing literature by taking this one step further and examine the surviving of new and existing firms that are run by elder individuals (one-em¬ployee firms) or have a high share of elderly individuals. Elderly individuals are defined as those above the age of 55 or 64. The results show that the average marginal effect on the prob-ability of survival from individuals above 55 and 64 differs across firm size. Elderly individuals negatively influence the survival of smaller firms (below ten employees). For larger firms the negative effect from elderly individuals is smaller, zero or even positive. Exploring the data, we find that “elderly firms”, defined as firms that have a majority of employees above the age of 55 or above the age of 64, have a lower survival rate and lower average number of employees but a higher value added per employee.
A "Tetris-Like" Model for the Compaction of Dry Granular Media

We propose a two-dimensional geometrical model, based on the concept of geometrical frustration, conceived for the study of compaction in granular media. The dynamics exhibits an interesting inverse logarithmic law that is well known from real experiments. Moreover, we present a simple dynamical model of $N$ planes exchanging particles with excluded volume problems, which allows us to clarify the origin of the logarithmic relaxations and the stationary density distribution. A simple mapping allows us to cast this Tetris-like model in the form of an Ising-like spin system with vacancies.
Does Parental Divorce Affect Adolescents' Cognitive Development? Evidence from Longitudinal Data

In this paper we analyse data from the National Education Longitudinal Study of 1988 to investigate whether experiencing parental divorce during adolescence reduces measured cognitive ability. To account for the potential endogeneity of parental divorce we employ a difference-in-differences model that relies on observing teenagers' outcomes before and after divorce. We find that parental divorce does not negatively affect teenagers' cognitive development. Our results also suggest that cross-section estimates overstate the detrimental effect of parental divorce.
Making wider use of the world's most widely used vaccine: Bacille Calmette–Guérin revaccination reconsidered

Approximately 100 million newborn children receive Bacille Calmette–Guérin (BCG) annually, because vaccination is consistently protective against childhood tuberculous meningitis and miliary TB. By contrast, BCG efficacy against pulmonary TB in children and adults is highly variable, ranging from 0% to 80%, though it tends to be higher in individuals who have no detectable prior exposure to mycobacterial infections, as judged by the absence of delayed-type hypersensitivity response (a negative tuberculin skin test, TST). The duration of protection against pulmonary TB is also variable, but lasts about 10 years on average. These observations raise the possibility that BCG revaccination, following primary vaccination in infancy, could be efficacious among TST-negative adolescents as they move into adulthood, the period of highest risk for pulmonary disease. To inform continuing debate about revaccination, this paper assesses the effectiveness and cost-effectiveness of revaccinating adolescents in a setting with intense transmission—Cape Town, South Africa. For a cost of revaccination in the range US$1–10 per person, and vaccine efficacy between 10% and 80% with protection for 10 years, the incremental cost per year of healthy life recovered (disability-adjusted life years, DALY) in the vaccinated population lies between US$116 and US$9237. The intervention is about twice as cost-effective when allowing for the extra benefits of preventing transmission, with costs per DALY recovered in the range US$52–$4540. At 80% efficacy, revaccination averted 17% of cases. Under the scenarios investigated, BCG revaccination is cost-effective against international benchmarks, though not highly effective. Cost-effectiveness ratios would be more favourable if we also allow for TB cases averted by preventing transmission to HIV-positive people, for the protection of HIV-negative people who later acquire HIV infection, for the possible non-specific benefits of BCG, for the fact that some adolescents would receive BCG for the first time, and for cost sharing when BCG is integrated into an adolescent immunization programme. These findings suggest, subject to further evaluation, that BCG revaccination could be cost-effective in some settings.
The Implementation Duality the Implementation Duality

We use the theory of abstract convexity to study adverse-selection principal-agent problems and two-sided matching problems, departing from much of the literature by not requiring quasilinear utility. We formulate and characterize a basic underlying implementation duality. We show how this duality can be used to obtain a sharpening of the taxation principle, to obtain a general existence result for solutions to the principal-agent problem, to show that (just as in the quasilinear case) all increasing decision functions are implementable under a single crossing condition, and to obtain an existence result for stable outcomes featuring positive assortative matching in a matching model.
Industry Tournament Incentives and Product Innovation

This paper examines how the tournament-like progression in CEO labor market influence product innovation. We exploit a text-based proxy for product innovation based on product descriptions from 10-Ks. We find a significant positive relation between industry tournament incentives and product innovation. Further, we show that product market competition strengthens this relation. Additionally, we explore that industry tournament incentives are more effective when the CEO labor market is more mobile and when CEO characteristics indicate a higher probability of winning the tournament prize. Overall, the evidence suggests that industry tournament incentives promote product innovation. JEL classifications: G32, J31, J33, O31, O32
Analysis of large MIMO DS-CDMA systems with imperfect CSI and spatial correlation

The large system analysis of randomly spread MIMO DS-CDMA systems is provided. Correlated Rayleigh fading MIMO channels are assumed for all users. Linear multiuser detection with separate decoding and pilot-aided channel estimation are used. The results imply that with channel estimation, the performance can improve significantly as the correlation between the transmit antennas increases. No channel information at the transmitter is required, but the channel estimator needs knowlegde of the long term transmit correlation in advance. The numerical results demonstrate that in a 4 × 4 MIMO DS-CDMA system with two users per chip, high antenna correlation at the transmitter can double the ergodic spectral efficiency compared to the case of uncorrelated transmit antennas.
Interaction of Classical Platinum Agents with the Monomeric and Dimeric Atox1 Proteins: A Molecular Dynamics Simulation Study

We carried out molecular dynamics simulations and free energy calculations for a series of binary and ternary models of the cisplatin, transplatin and oxaliplatin agents binding to a monomeric Atox1 protein and a dimeric Atox1 protein to investigate their interaction mechanisms. All three platinum agents could respectively combine with the monomeric Atox1 protein and the dimeric Atox1 protein to form a stable binary and ternary complex due to the covalent interaction of the platinum center with the Atox1 protein. The results suggested that the extra interaction from the oxaliplatin ligand–Atox1 protein interface increases its affinity only for the OxaliPt + Atox1 model. The binding of the oxaliplatin agent to the Atox1 protein might cause larger deformation of the protein than those of the cisplatin and transplatin agents due to the larger size of the oxaliplatin ligand. However, the extra interactions to facilitate the stabilities of the ternary CisPt + 2Atox1 and OxaliPt + 2Atox1 models come from the α1 helices and α2-β4 loops of the Atox1 protein–Atox1 protein interface due to the cis conformation of the platinum agents. The combinations of two Atox1 proteins in an asymmetric way in the three ternary models were analyzed. These investigations might provide detailed information for understanding the interaction mechanism of the platinum agents binding to the Atox1 protein in the cytoplasm.
Fractionation of sulfur isotopes by Desulfovibrio vulgaris mutants lacking hydrogenases or type I tetraheme cytochrome c3

The sulfur isotope effect produced by sulfate reducing microbes is commonly used to trace biogeochemical cycles of sulfur and carbon in aquatic and sedimentary environments. To test the contribution of intracellular coupling between carbon and sulfur metabolisms to the overall magnitude of the sulfur isotope effect, this study compared sulfur isotope fractionations by mutants of Desulfovibrio vulgaris Hildenborough. We tested mutant strains lacking one or two periplasmic (Hyd, Hyn-1, Hyn-2, and Hys) or cytoplasmic hydrogenases (Ech and CooL), and a mutant lacking type I tetraheme cytochrome (TpI-c3). In batch culture, wild-type D. vulgaris and its hydrogenase mutants had comparable growth kinetics and produced the same sulfur isotope effects. This is consistent with the reported redundancy of hydrogenases in D. vulgaris. However, the TpI-c3 mutant (ΔcycA) exhibited slower growth and sulfate reduction rates in batch culture, and produced more H2 and an approximately 50% larger sulfur isotope effect, compared to the wild type. The magnitude of sulfur isotope fractionation in the CycA deletion strain, thus, increased due to the disrupted coupling of the carbon oxidation and sulfate reduction pathways. In continuous culture, wild-type D. vulgaris and the CycA mutant produced similar sulfur isotope effects, underscoring the influence of environmental conditions on the relative contribution of hydrogen cycling to the electron transport. The large sulfur isotope effects associated with the non-ideal stoichiometry of sulfate reduction in this study imply that simultaneous fermentation and sulfate reduction may be responsible for some of the large naturally-occurring sulfur isotope effects. Overall, mutant strains provide a powerful tool to test the effect of specific redox proteins and pathways on sulfur isotope fractionation.
Modeling Roadside Attacker Behavior in VANETs

Communication using VANETs is commonly seen as the next milestone for improving traffic safety. Vehicles will be enabled to exchange any kind of information that helps to detect and mitigate dangerous situations. Security research in the past years has shown that VANETs are endangered by a plethora of severe security risk. Subject of this work is the modeling of attackers that target active safety applications in VANETs. Through a risk analysis, this work identifies assets, threats and potential attacks in inter-vehicle communication. The risk analysis shows that the most serious threat arises from a quasi-stationary (road-side) attacker that distributed forged warning messages. This attacker is discussed more deeply. We show the degrees of freedom that are available for position forging and find thereby two attacks that demand attention: single position forging having low effort compared to sophisticated movement path forging having a potentially high influence on road traffic safety.
Cytoplasmic signalling by the c‐Abl tyrosine kinase in normal and cancer cells

c‐Abl is a non‐receptor tyrosine kinase which is localized both in the nucleus and cytoplasm, and is involved in the regulation of cell growth, survival and morphogenesis. Although c‐Abl nuclear function has been extensively studied, recent data also indicate an important role in cytoplasmic signalling through mitogenic and adhesive receptors. Here, we review the mechanisms by which growth factors promote cytoplasmic c‐Abl activation and signalling and its function in the induction of DNA synthesis, changes in cell morphology and receptor endocytosis. The importance of de‐regulated c‐Abl cytoplasmic signalling in solid tumours is also discussed.
When weak governments confront inclusive trade unions: The politics of protecting labour market outsiders in the age of dualization

Some European welfare states protect outsiders from economic uncertainty better than others. Conventional theories attribute this either to the material interests of producer groups or the vote-seeking actions of political parties. By contrast, this article focuses on the interaction between trade unions and governments, drawing on empirical experience in Austria and Sweden. High levels of inclusiveness provide trade unions with a powerful interest in protecting outsiders. Governments, however, have moved towards dualistic policy choices, but when weakened by intra-coalitional divisions or a hung parliament, they retain a political incentive to negotiate political deals with trade unions, and this forces them to compensate outsiders for economic uncertainty.
Detecting Table Region in PDF Documents Using Distant Supervision

Superior to state-of-the-art approaches which compete in table recognition with 67 annotated government reports in PDF format released by {\it ICDAR 2013 Table Competition}, this paper contributes a novel paradigm leveraging large-scale unlabeled PDF documents to open-domain table detection. We integrate the paradigm into our latest developed system ({\it PdfExtra}) to detect the region of tables by means of 9,466 academic articles from the entire repository of {\it ACL Anthology}, where almost all papers are archived by PDF format without annotation for tables. The paradigm first designs heuristics to automatically construct weakly labeled data. It then feeds diverse evidences, such as layouts of documents and linguistic features, which are extracted by {\it Apache PDFBox} and processed by {\it Stanford NLP} toolkit, into different canonical classifiers. We finally use these classifiers, i.e. {\it Naive Bayes}, {\it Logistic Regression} and {\it Support Vector Machine}, to collaboratively vote on the region of tables. Experimental results show that {\it PdfExtra} achieves a great leap forward, compared with the state-of-the-art approach. Moreover, we discuss the factors of different features, learning models and even domains of documents that may impact the performance. Extensive evaluations demonstrate that our paradigm is compatible enough to leverage various features and learning models for open-domain table region detection within PDF files.
Stochastic Stability of Differential Equations in Abstract Spaces

We begin by recalling some basic definitions and results, especially those from functional analysis, partial differential equations (PDEs), probability, and stability theories. We review basic notions and notations from deterministic systems and recall important results from stochastic differential equations. We introduce two notions of solutions, mild and strong, for infinite-dimensional stochastic differential equations and consider the existence and uniqueness of solutions under suitable assumptions. We introduce and clarify various definitions of stochastic stability in Hilbert spaces, which are a natural generalization of deterministic stability concepts. To present the proofs of all the results here would require preparatory background material that would significantly increase both the size and scope of this book. Therefore, we adopt the approach of omitting those proofs, which are treated in detail in wellknown standard textbooks such as Da Prato and Zabczyk [53], Pazy [187], and Yosida [224]. However, those proofs will be presented that are not available in the existing books and are to be found scattered in the literature, or that discuss ideas specially relevant to our purpose.
