Spectrum sharing between the Mobile Service and existing fixed and fixed satellite services in the 3.6–3.8 GHz band

European administrations are currently in the process of defining national spectrum sharing frameworks to enable coexistence between new entrant Mobile/Fixed Communication Networks (MFCNs) and the incumbent Fixed Satellite Service (FSS) downlink and Fixed Service (FS) in the 3.6-3.8 GHz band. In this paper we propose a methodology for establishing such frameworks whereby administrations define criteria for the protection of the incumbent users in the form of maximum permitted interference levels at the input of the FSS and FS receivers. These limits are then used to calculate either geographic exclusion zones or the maximum permitted radiated powers of MFCN base stations, so as to avoid harmful interference to the FSS and FS. The above calculations can be performed by the MFCN operators, the administration, or a third party. We also set out a number of novel options to account for interference aggregation and the partitioning of the interference budget across multiple MFCN base stations and operators. There is always a trade-off between the simplicity of a spectrum sharing framework and spectrum sharing efficiency. The proposed methodology provides the flexibility for administrations to exploit this trade-off according to their specific national circumstances.
Efficacy of Interventions for Sexually Abused Children – A Literature Review and Meta-Analysis of Treatment of Post Traumatic Stress Symptoms

Background : Child sexual abuse is a significant risk factor for psychopathology. Earlier reviews indicate that psychosocial interventions may be effective for some symptoms, but a comprehensive picture is still lacking. Moreover, the rapid increase of research requires evaluations to be updated. The present systematic review aims at describing the research on intervention efficacy among sexually abused children, and analyses their effect in decreasing the post traumatic stress symptoms (PTSS). Methods : The qualitative literature review offers the overview of recent interventions among sexually abused children. It describes the quality of evidence as well as the modality (group vs. individual, family vs. child only) and targeting (universal, selective, indicated) of the interventions. To evaluate the efficacy of interventions, the meta-analysis is applied. Results : The results revealed 23 relevant studies with total of 31 intervention conditions published between 2000 and 2013. The meta-analysis showed that when intervention groups were compared to control groups with no treatment at all, interventions showed a large power of positive changes in PTSS. However, when cognitive behavioral therapy (CBT) groups were compared to control groups which received some other intervention, there was no difference in PTSS changes among experimental and control groups. Conclusions : Results suggest that psychosocial interventions with sexually abused children are beneficial but it is still not clear, which are the most effective methods. The results also highlight the consequences of methodological decisions when conducting meta-analysis. However, because of some limitations of the study, the results of this review should be regarded as tentative and suggestive and further elaboration of the constantly growing evidence is needed.
Determination of Cod and Color Reduction of Stabilized Landfill Leachate by Fenton Process

The Fenton process on landfill leachate was done in a batch reactor. The application of Fenton treatment technology for landﬁll leachate treatment greatly depends on the optimum Fenton operating conditions. The present study investigated the chemical oxygen demand (COD) and color removal efficiency of a non-biodegradable leachate by Fenton process. Determining optimum Fenton conditions requires multiple experiments using variable reaction parameters (pH, temperature, and H2O2 and Fe2+ doses). The treatment showed that the leachate organics can be broke down by the use of Fenton? s reagent. The result showed that with increasing H2O2 dosage, H2O2/Fe2+ ratio and decreasing the pH and contact time, the COD and color removal increased. The laboratory result determined that the best functional situation to catch the goals _ (i.e., BOD5/COD =0.1) resulted; pH=3, Contact time=30 minutes, H2O2 concentration= 40000 mgL-1 and the favorable H2O2/Fe2+ ratio = 10.
Intraindividual variability and stability of affect and well-being: Short-term and long-term change and stabilization processes.

Whereas subjective well-being remains relatively stable across adulthood, emotional experiences show remarkable short-term variability, with younger and older adults differing in both amount and correlates. Repeatedly assessed affect data captures both the dynamics and stability as well as stabilization that may indicate emotion-regulatory processes. The article reviews (1) research approaches to intraindividual affect variability, (2) functional implications of affect variability, and (3) age differences in affect variability. Based on this review, we discuss how the broader literature on emotional aging can be better integrated with theories and concepts of intraindividual affect variability by using appropriate methodological approaches. Finally, we show how a better understanding of affect variability and its underlying processes could contribute to the long-term stabilization of well-being in old age.
Ieee Transactions on Evolutionary Computation 1

This article has been accepted for publication in a future issue of this journal, but has not been fully edited. Content may change prior to final publication.  Abstract—Evolutionary algorithms have been successfully exploited to solve multiobjective optimization problems. In literature, a heuristic approach is often taken. For a chosen benchmark problem with specific problem characteristics, the performance of multiobjective evolutionary algorithms (MOEAs) is evaluated via some heuristic chosen performance metrics. The conclusion is then drawn based on statistical findings given the preferable choices of performance metrics. The conclusion, if any, is often indecisive and reveals no insight pertaining to specific problem characteristics that the underlying MOEA could perform the best. In this paper, we introduce an ensemble method to compare MOEAs by combining a number of performance metrics using double elimination tournament selection. The double elimination design allows characteristically poor performance of a quality algorithm to still be able to win it all. Experimental results show that the proposed metrics ensemble can provide a more comprehensive comparison among various MOEAs than what could be obtained from single performance metric alone. The end result is a ranking order among all chosen MOEAs, but not quantifiable measures pertaining to the underlying MOEAs.
The Effects of Violent Music on Children and Adolescents

The best music. is essentially there to provide you something to face the world with. —Bruce Springsteen Music can change the world. —Ludwig van Beethoven Music is spiritual. The music business is not. —Van Morrison Although much of the debate about the effects of media on youth revolves around television, music is very important to children and adolescents. Try to change the radio station in the car after your child has set it, and you will quickly see that they have very clear and deeply held opinions. In a survey of junior and senior high school students in northern California (Roberts & Henriksen, 1990), students were asked what media they would choose to take with them if they were stranded on a desert island. They were allowed to nominate a first, second, and third choice from a list including: and music recordings and the means to play them. Because radio is almost exclusively a music medium for adolescents, radio and recordings were combined into a single " music " category. As Table 8.1 displays, at all grade levels, music media were preferred over television (which placed second overall), and this preference increased with age. Over 80 percent of the total sample nominated music as one of their first three choices. By eleventh grade, music was selected first by a margin of two to one.
Chromosome Aberrations Resulting From Double-Strand DNA Breaks at a Naturally Occurring Yeast Fragile Site Composed of Inverted Ty Elements Are Independent of Mre11p and Sae2p

Genetic instability at palindromes and spaced inverted repeats (IRs) leads to chromosome rearrangements. Perfect palindromes and IRs with short spacers can extrude as cruciforms or fold into hairpins on the lagging strand during replication. Cruciform resolution produces double-strand breaks (DSBs) with hairpin-capped ends, and Mre11p and Sae2p are required to cleave the hairpin tips to facilitate homologous recombination. Fragile site 2 (FS2) is a naturally occurring IR in Saccharomyces cerevisiae composed of a pair of Ty1 elements separated by ∼280 bp. Our results suggest that FS2 forms a hairpin, rather than a cruciform, during replication in cells with low levels of DNA polymerase. Cleavage of this hairpin results in a recombinogenic DSB. We show that DSB formation at FS2 does not require Mre11p, Sae2p, Rad1p, Slx4p, Pso2p, Exo1p, Mus81p, Yen1p, or Rad27p. Also, repair of DSBs by homologous recombination is efficient in mre11 and sae2 mutants. Homologous recombination is impaired at FS2 in rad52 mutants and most aberrations reflect either joining of two broken chromosomes in a “half crossover” or telomere capping of the break. In support of hairpin formation precipitating DSBs at FS2, two telomere-capped deletions had a breakpoint near the center of the IR. In summary, Mre11p and Sae2p are not required for DSB formation at FS2 or the subsequent repair of these DSBs.
Hiding Global Communication Latency in the GMRES Algorithm on Massively Parallel Machines

In the generalized minimal residual method (GMRES), the global all-to-all communication required in each iteration for orthogonalization and normalization of the Krylov base vectors is becoming a performance bottleneck on massively parallel machines. Long latencies, system noise, and load imbalance cause these global reductions to become very costly global synchronizations. In this work, we propose the use of nonblocking or asynchronous global reductions to hide these global communication latencies by overlapping them with other communications and calculations. A pipelined variation of GMRES is presented in which the result of a global reduction is used only one or more iterations after the communication phase has started. This way, global synchronization is relaxed and scalability is much improved at the expense of some extra computations. The numerical instabilities that inevitably arise due to the typical monomial basis by powering the matrix are reduced and often annihilated by using Newton or Chebysh.
The rise and decline in Salmonella enterica serovar Enteritidis outbreaks attributed to egg-containing foods in the United States, 1973–2009

SUMMARY Salmonella enterica causes an estimated 1 million domestically acquired foodborne illnesses annually. Salmonella enterica serovar Enteritidis (SE) is among the top three serovars of reported cases of Salmonella. We examined trends in SE foodborne outbreaks from 1973 to 2009 using Joinpoint and Poisson regression. The annual number of SE outbreaks increased sharply in the 1970s and 1980s but declined significantly after 1990. Over the study period, SE outbreaks were most frequently attributed to foods containing eggs. The average rate of SE outbreaks attributed to egg-containing foods reported by states began to decline significantly after 1990, and the proportion of SE outbreaks attributed to egg-containing foods began declining after 1997. Our results suggest that interventions initiated in the 1990s to decrease SE contamination of shell eggs may have been integral to preventing SE outbreaks.
Robust system portfolio selection with multi-function requirements and system instability

System Portfolio Selection (SPS) problem is equivalent to multi-objective optimization problem, with multi-function requirements incommensurable. In the paper, the SPS problem is re-specified with a more practical formulation, comparing to general portfolio problem. Then, both feasible and non-inferior solution is re-defined considering characteristics of SPS problem, specifically, four rules of system function combinations are proposed according to practical cases. Then, the instability of system performance is involved in SPS problem, and the robust theory is employed to solving the uncertainty of system function values with definition of robust non-inferior solution. Next, the paper proposes an immediately updating algorithm to solve the problem of solution space exponentially growing. Finally, a case study is used to demonstrate the usefulness and effectiveness of the proposed approaches. It shows that the approach can provide an efficient guidance for decision-makers in the process of making a SPS.
All-or-Nothing Transforms Using Quasigroups

In this paper we suggest a new transformation scheme for All-Or-Nothing encryption, originally suggested by Rivest. The new transform concerns the use of quasigroups for the preprocessing of the data before any ordinary encryption method. We describe a method of constructing random quasigroups and we propose a way of using the advantages of quasigroup in Rivest's method. This combination makes the method faster and maintains the advantages against brute-force attacks.
A New Determinant Expression of the Zeta Function for a Hypergraph

Recently, Storm defined the Ihara-Selberg zeta function of a hypergraph, and gave two determinant expressions of it by the Perron-Frobenius operator of a digraph and a deformation of the usual Laplacian of a graph. We present a new determinant expression for the Ihara-Selberg zeta function of a hypergraph, and give a linear algebraic proof of Storm's Theorem. Furthermore, we generalize these results to the Bartholdi zeta function of a hypergraph.
Studying the Impact of the Lesson Analysis Framework on Preservice Teachers’ Abilities to Reflect on Videos of Classroom Teaching

This study investigates the impact of an observation framework on preservice teachers’ abilities to engage in productive video-based reflections on mathematics teaching. The Lesson Analysis Framework draws from research on expert—novice teacher differences. Its central element is the analysis of the impact of teachers’ instructional decisions on students’ learning of mathematics. Through an experimental design, the effects of this framework on preservice teachers’ abilities to reflect on teaching are compared to the effects of an alternative framework focused on the evaluation of separate elements of instruction. Findings suggest that the Lesson Analysis Framework facilitates preservice teachers’ learning to elaborate on what they observe and to propose alternative teaching strategies. In addition, the framework provides a structure for evidence-based evaluation of observed instruction.
Changes in problem-solving appraisal after cognitive therapy for the prevention of suicide

Background Cognitive therapy has been found to be effective in decreasing the recurrence of suicide attempts. A theoretical aim of cognitive therapy is to improve problem-solving skills so that suicide no longer remains the only available option. This study examined the differential rate of change in problem-solving appraisal following suicide attempts among individuals who participated in a randomized controlled trial for the prevention of suicide. Method Changes in problem-solving appraisal from pre- to 6-months post-treatment in individuals with a recent suicide attempt, randomized to either cognitive therapy (n=60) or a control condition (n=60), were assessed by using the Social Problem-Solving Inventory-Revised, Short Form. Results Improvements in problem-solving appraisal were similarly observed for both groups within the 6-month follow-up. However, during this period, individuals assigned to the cognitive therapy condition demonstrated a significantly faster rate of improvement in negative problem orientation and impulsivity/carelessness. More specifically, individuals receiving cognitive therapy were significantly less likely to report a negative view toward life problems and impulsive/carelessness problem-solving style. Conclusions Cognitive therapy for the prevention of suicide provides rapid changes within 6 months on negative problem orientation and impulsivity/carelessness problem-solving style. Given that individuals are at the greatest risk for suicide within 6 months of their last suicide attempt, the current study demonstrates that a brief cognitive intervention produces a rapid rate of improvement in two important domains of problem-solving appraisal during this sensitive period.
SUTLER: Update Summarizer Based on Latent Topics

This paper deals with our past and recent research in text summarization. We went from single-document summarization through multidocument summarization to update summarization. We describe the development of our summarizer which is based on latent semantic analysis (LSA). The classical LSA-based summarization model was improved by Iterative Residual Rescaling. We propose the update summarization component which determines the redundancy and novelty of each topic discovered by LSA. Moreover, we have modified the sentence selection component in order to prevent inner summary redundancy. The results of our first participation in TAC/DUC evaluation seem to be promising.
Decomposing Sets of Inversions

In this paper we consider the question how the set of inversions of a permutation $\pi \in S_n$ can be partitioned into two subsets, which are themselves inversion sets of permutations in $S_n$. Our method is to study the modular decomposition of the inversion graph of $\pi$. A correspondence to the substitution decomposition of $\pi$ is also given. Moreover, we consider the special case of multiplicative decompositions.
Barriers of Influenza Vaccination Intention and Behavior – A Systematic Review of Influenza Vaccine Hesitancy, 2005 – 2016

Background Influenza vaccine hesitancy is a significant threat to global efforts to reduce the burden of seasonal and pandemic influenza. Potential barriers of influenza vaccination need to be identified to inform interventions to raise awareness, influenza vaccine acceptance and uptake. Objective This review aims to (1) identify relevant studies and extract individual barriers of seasonal and pandemic influenza vaccination for risk groups and the general public; and (2) map knowledge gaps in understanding influenza vaccine hesitancy to derive directions for further research and inform interventions in this area. Methods Thirteen databases covering the areas of Medicine, Bioscience, Psychology, Sociology and Public Health were searched for peer-reviewed articles published between the years 2005 and 2016. Following the PRISMA approach, 470 articles were selected and analyzed for significant barriers to influenza vaccine uptake or intention. The barriers for different risk groups and flu types were clustered according to a conceptual framework based on the Theory of Planned Behavior and discussed using the 4C model of reasons for non-vaccination. Results Most studies were conducted in the American and European region. Health care personnel (HCP) and the general public were the most studied populations, while parental decisions for children at high risk were under-represented. This study also identifies understudied concepts. A lack of confidence, inconvenience, calculation and complacency were identified to different extents as barriers to influenza vaccine uptake in risk groups. Conclusion Many different psychological, contextual, sociodemographic and physical barriers that are specific to certain risk groups were identified. While most sociodemographic and physical variables may be significantly related to influenza vaccine hesitancy, they cannot be used to explain its emergence or intensity. Psychological determinants were meaningfully related to uptake and should therefore be measured in a valid and comparable way. A compendium of measurements for future use is suggested as supporting information.
Floral specialization and angiosperm diversity: phenotypic divergence, fitness trade-offs and realized pollination accuracy

This review considers the role of reproductive factors in the evolutionary success of flowering plants, with emphasis on flowers and pollination. Flowers are complex structures that have varying degrees of integration of parts and surprising evolutionary lability. Diversification of floral form usually accompanies plant diversification by speciation. This correlation has traditionally been interpreted as the result of floral specialization increasing speciation rates. However, another possibility is that species diversity generates selection for divergent specialized flowers when related species occur together, thereby reducing extinction rates.
An Efficient Algorithm for Frequent Closed Itemsets Mining

Efficient algorithms for mining frequent itemsets are crucial for mining association rules. Most existing work focuses on mining all frequent itemsets. However, since any subset of a frequent set also is frequent, it is sufficient to mine the set of frequent closed itemsets which determines exactly the complete set of all frequent itemsets and is usually much smaller than the laster. In this paper, we study the performance of the existing approaches for mining frequent closed itemsets. We also develop an algorithm, called FCFIA. In this algorithm, we develop and integrate two techniques in order to improve the efficiency of mining frequent closed itemsets. We also present experimental results which show that our method outperforms the existing methods FPclose.
Straightening Beta: Overdispersion of Lethal Chromosome Aberrations following Radiotherapeutic Doses Leads to Terminal Linearity in the Alpha–Beta Model

Recent technological advances allow precise radiation delivery to tumor targets. As opposed to more conventional radiotherapy—where multiple small fractions are given—in some cases, the preferred course of treatment may involve only a few (or even one) large dose(s) per fraction. Under these conditions, the choice of appropriate radiobiological model complicates the tasks of predicting radiotherapy outcomes and designing new treatment regimens. The most commonly used model for this purpose is the venerable linear-quadratic (LQ) formalism as it applies to cell survival. However, predictions based on the LQ model are frequently at odds with data following very high acute doses. In particular, although the LQ predicts a continuously bending dose–response relationship for the logarithm of cell survival, empirical evidence over the high-dose region suggests that the survival response is instead log-linear with dose. Here, we show that the distribution of lethal chromosomal lesions among individual human cells (lymphocytes and fibroblasts) exposed to gamma rays and X rays is somewhat overdispersed, compared with the Poisson distribution. Further, we show that such overdispersion affects the predicted dose response for cell survival (the fraction of cells with zero lethal lesions). This causes the dose response to approximate log-linear behavior at high doses, even when the mean number of lethal lesions per cell is well fitted by the continuously curving LQ model. Accounting for overdispersion of lethal lesions provides a novel, mechanistically based explanation for the observed shapes of cell survival dose responses that, in principle, may offer a tractable and clinically useful approach for modeling the effects of high doses per fraction.
