Statistical Prediction of Spectrum Occupancy Perception in Dynamic Spectrum Access Networks

Cognitive radio nodes of a dynamic spectrum access network monitor the spectrum around them in order to detect and opportunistically exploit temporarily unoccupied spectrum gaps. The overall behavior of the whole network depends on the spectrum occupancy perceived by each node at its local environment. An appropriate understanding of the local perception of cognitive radio nodes in various scenarios and locations as well as its dependence on the propagation environment can provide valuable information for the design, dimensioning and performance evaluation of dynamic spectrum access networks. In this context, this work presents a novel and practical approach to predict the spectrum occupancy that would be perceived by cognitive radio nodes in realistic scenarios. Based on such approach, we explore the dependence of the spectrum occupancy perception with the considered scenario and location as well as the impact of particular parameters of the radio environment.
Proliferative enteropathy: a global enteric disease of pigs caused by Lawsonia intracellularis

Abstract Proliferative enteropathy (PE; ileitis) is a common intestinal disease affecting susceptible pigs raised under various management systems around the world. Major developments in the understanding of PE and its causative agent, Lawsonia intracellularis, have occurred that have led to advances in the detection of this disease and methods to control and prevent it. Diagnostic tools that have improved overall detection and early onset of PE in pigs include various serological and molecular-based assays. Histological tests such as immunohistochemistry continue to be the gold standard in confirming Lawsonia-specific lesions in pigs post mortem. Despite extreme difficulties in isolating L. intracellularis, innovations in the cultivation and the development of pure culture challenge models, have opened doors to better characterization of the pathogenesis of PE through in vivo and in vitro L. intracellularis–host interactions. Advancements in molecular research such as the genetic sequencing of the entire Lawsonia genome have provided ways to identify various immunogens, metabolic pathways and methods for understanding the epidemiology of this organism. The determinations of immunological responsiveness in pigs to virulent and attenuated isolates of L. intracellularis and identification of various immunogens have led to progress in vaccine development.
FRAME ANALYSIS OF POLITICAL TEXTS

The article outlines the study of political texts from psycholinguistic perspectives. The research generalizes and empirically verifies a psycholinguistic approach to the study of political discourse and focuses on frame analysis, one of the most powerful psycholinguistic techniques. Frame structure embraces conceptual components that allow accumulating information from different sources. The public speeches of two great Ukrainian and American political leaders Viktor Yushchenko and Barack Obama were the principal sources of the analysis. Frame analysis was applied to study cross-cultural peculiarities that depict national nature of two cultures. Data analysis shows that discourse of the Ukrainian leader is mostly focused on categories such as people, power, liberty. The discourse of the American leader contains categories such as economy, money, people, psychological constructs. The results show that people have become top-priority for V. Yushchenko. They are the people the Ukrainian politician addresses, believes and trusts. V. Yushchenko also focuses on freedom, independence and liberty of any Ukrainian citizen. B. Obama is deeply concentrated on economy and finance of his country. It has become obvious that he is ready to imple ment the set of reforms for the country to thrive. The category of psychological constructs shows that the American politician is full of respect and proud for his country ant population. The radical variety of two speeches is caused by different economic conditions, values and mentality of two cultures and personal purposes and objectives of the two politicians.

Improving Embedded Machine Translation with User

Automated machine translation (MT) of unrestricted texts is known to be error-prone, and thus typically requires human involvement in the translation process to achieve acceptable quality. In a conversational system performing interactive speech translation between two speakers, neither pre-editing nor conventional post-editing is possible, and the users will generally have no direct access to the embedded MT component. Since most translation errors are the result of incorrect selections, one approach to solving the dilemma is to provide the user with access to various alternative translations and allow him to select the one which appears correct in context. If the system remembers the manual selections, it can make the correct selection automatically whenever the same context is encountered thereafter.
On the optimal routing for Reconfigurable Network Architecture

The over 40-year old Internet, which was designed and proposed with the intention to interconnect several computing resources across a geographically distributed user group, is now facing many unprecedented challenges especially from the increasingly abundant demands in future networks. Traditional IP protocol can hardly deal with the challenges due to the single function and low QoS. In this paper, we proposed a unified polymorphic routing method towards the Reconfigurable Network Architecture (RNA) to achieve diverse demands according to different business types. Then, a rough description of specific based routing method is given in conjunction with the stipulated packet header that is compatible with current IP. Moreover, the network business match rate of polymorphic routing for RNA is simulated to validate the effectiveness and feasibility.
Discriminating Males and Unpredictable Females: Males Differentiate Self-Similar Facial Cues More than Females in the Judgment of Opposite-Sex Attractiveness

Attractiveness judgment in the context of mate preferences is thought to reflect an assessment of mate quality in relation to an absolute scale of genetic fitness and a relative scale of self-similarity. In this study, subjects judged the attractiveness and trustworthiness of faces in composite images that were manipulated to produce self-similar (self-resemblance) and dissimilar (other-resemblance) images. Males differentiated between self- and other-resemblance as well as among different degrees of self-resemblance in their attractiveness ratings; females did not. Specifically, in Experiment 1, using a morphing technique, we created previously unseen face images possessing different degrees (0%, 30%, 40%, or 50%) of incorporation of the subject's images (different degrees of self-resemblance) and found that males preferred images that were closer to average (0%) rather than more self-similar, whereas females showed no preference for any degree of self-similarity. In Experiment 2, we added a pro-social question about trustworthiness. We replicated the Experiment 1 attractiveness rating results and further found that males differentiated between self- and other-resemblance for the same degree of composites; women did not. Both males and females showed a similar preference for self-resemblances when judging trustworthiness. In conclusion, only males factored self-resemblance into their attractiveness ratings of opposite-sex individuals in a manner consistent with cues of reproductive fitness, although both sexes favored self-resemblance when judging trustworthiness.
Elementary Teachers' Assessment Beliefs and Practices

ELEMENTARY TEACHERS’ ASSESSMENT BELIEFS AND PRACTICES By Sarah B. Calveric, Ph.D. A dissertation submitted in partial fulfillment of the requirements for the deg ree of Doctor of Philosophy at Virginia Commonwealth University. Virginia Commonwealth University, 2010 Director: Dr. James McMillan Foundations of Education School of Education Increased state and federal accountability measures have made the asse ssment of student performance one of the most critical responsibilities of classroom teachers; yet, inadequate opportunities for preservice and inservice training leave many teachers feel ing ill-prepared for this task. Adding to the complexity of building teachers’ assessment literacy is the relationship between assessment beliefs and classroom assessment practices. This quantitative study utilizes a validated, online survey to examine how elementary teachers (n = 79) define thei r assessment beliefs (conceptions) and how these beliefs influence which assessment prac tices re valued within the classroom. Findings suggest that despite teachers’ limited ex posure to assessment training, four distinct assessment beliefs exist within the elementary classroom: assessment for school accountability, assessment for student certification, assessment for i mpr vement of teaching and learning, and assessment as irrelevant. Assessment for the i mprov ment of teaching and learning yielded the highest composite mean and was negatively correla ted with the irrelevance belief and positively related to school accountability. An ana lysis of the importance of assessment practices revealed authentic assessments, short answers, t eacher-made assessments, and performance assessments as the most valued, while publisher as sessment and major exams had the lowest means. Significant relationships were identified be tween demographics and beliefs and practices, with the most practical findings rel ated to exposure to assessment training and level of degree attainment. Significant relations hips were also noted between all beliefs and the value of specific assessment practices, with the exception of the irrelevance belief. No significant relationships were noted between the irre levant belief and value of assessment practices; however, many negative correlations were doc umented. Results are discussed in light of other research, indicating that a greater understanding of assessment beliefs and importance of practices can contribute to the development of relevant profe ssional development aimed at the improvement of teachers’ assessment pedagogies and p ractices can contribute to greater educational success.
Rerouting the Plant Phenylpropanoid Pathway by Expression of a Novel Bacterial Enoyl-CoA Hydratase/Lyase Enzyme Function

The gene for a bacterial enoyl-CoA hydratase (crotonase) homolog (HCHL) previously shown to convert 4-coumaroyl-CoA, caffeoyl-CoA, and feruloyl-CoA to the corresponding hydroxybenzaldehydes in vitro provided an opportunity to subvert the plant phenylpropanoid pathway and channel carbon flux through 4-hydroxybenzaldehyde and the important flavor compound 4-hydroxy-3-methoxybenzaldehyde (vanillin). Expression of the Pseudomonas fluorescens AN103 HCHL gene in two generations of tobacco plants caused the development of phenotypic abnormalities, including stunting, interveinal chlorosis and senescence, curled leaf margins, low pollen production, and male sterility. In second generation progeny, the phenotype segregated with the transgene and transgenic siblings exhibited orange/red coloration of the vascular ring, distorted cells in the xylem and phloem bundles, and lignin modification/reduction. There was depletion of the principal phenolics concomitant with massive accumulation of novel metabolites, including the glucosides and glucose esters of 4-hydroxybenzoic acid and vanillic acid and the glucosides of 4-hydroxybenzyl alcohol and vanillyl alcohol. HCHL plants exhibited increased accumulation of transcripts for phenylalanine ammonia-lyase, cinnamate-4-hydroxylase, and 4-coumarate:CoA ligase, whereas β-1,3-glucanase was suppressed. This study, exploiting the ability of a bacterial gene to divert plant secondary metabolism, provides insight into how plants modify inappropriately accumulated metabolites and reveals the consequences of depleting the major phenolic pools.
Exact Predictive Direct Power Control of three-level NPC converters for wind power applications

The Predictive Direct Power Control (P-DPC) strategy computes the application times of several voltage-vectors included in a predefined sequence. Until now only approximate solutions of the P-DPC have been presented. This contribution proposes two improvements to the P-DPC: the exact solution of the control problem and the fastest possible transient.
Neural processes underlying self- and other-related lies: An individual difference approach using fMRI

Abstract Two hypotheses were tested using a novel individual differences approach, which identifies rate-limiting brain regions, that is, brain regions in which variations in neural activity predict variations in behavioral performance. The first hypothesis is that the rate-limiting regions that support the production of lies about oneself (self-related) are partially distinct from those underlying the production of lies about other individuals (other-related). The second hypothesis is that a cingulate–insular–prefrontal network found to be rate-limiting for interference tasks is involved in both types of lies. The results confirmed both hypotheses and supported the utility of this individual differences approach in the study of deception in particular, as well in the study of complex cognitive phenomena more generally.
Cognitive Load, Scaffolding and an ILS Algebra Tutor

The support for the use of computers in teaching and learning is widespread. Some educationalist say that the most powerful use of computing technology is as a tool for cognitive amplification or to enable students to explore mathematical concepts, and through this exploration construct mathematical understandings. Others note that the increasing power of computers enables them to exhibit artificial intelligence that can be used as surrogate tutors of mathematics. The most recent of such programs are Integrated Learning Systems (ILS) that present lessons, assess student responses and provide remedial feedback as well as monitor student progress. This study examines how a student used the feedback and cognitive scaffolding potential of a new generation ILS algebra tutor, The Learning Equation, in her learning. It was found that the student did not follow the carefully constructed intended sequence of learning provided by the ILS. However, she used a just-in-time approach to accessing feedback and a reliance on syntactic structure that enabled her to use the software in a way that accounted for most of her cognitive support needs.

Self‐esteem and anxious responses to partner feedback: Parsing anticipatory and consummatory anxiety

Funding information National Institute of Mental Health, Grant/Award Number: T32 MH020006; PSC CUNY Grant, Grant/Award Number: 71736-0001 We hypothesized that people with lower self-esteem (SE) may perceive feedback from romantic partners in threatening ways and display maladaptive reactions during these events. Although prior research suggests that SE is mostly unrelated to emotional reactions to partner feedback, we predicted that differences in anxious emotion exist, but emerge before the feedback is delivered, at anticipation. We evaluated these predictions through a series of studies in which participants received feedback from ongoing and ostensible dating partners. As in prior research, SE was unrelated to anxiety at feedback delivery. In contrast, and consistent with predictions, participants with lower SE anticipated feeling more anxious when receiving positive and negative feedback. These results are discussed in the context of broader relationship dynamics.
Accelerating a PARSEC Benchmark Using Portable Subword SIMD

—We present a case study of the GNU Compiler Collection (GCC) Vector Extensions in GCC 4.7. In particular, we examine the relative performance of explicit vector code using the GCC Vector Extensions to that of automatically vectorized code from the Intel C++ Compiler (ICC). Our analysis focuses on the interactions between data-level and thread-level parallelism in the streamcluster benchmark from the PARSEC benchmark suite, in particular examining tradeoffs between portability and performance across different vectorization techniques.
New Techniques for the Analysis and Design of Coupled-Oscillator Systems

An in-depth analysis of the nonlinear dynamics of coupled-oscillator arrays is presented for a better understanding of their complex autonomous behavior. In one-dimensional arrays, the constant inter-stage phase shift is varied by simultaneously detuning the two outermost oscillators in opposite directions. Thus, the array can be considered as a two-parameter system. Here, a two-parameter stability analysis of the oscillator array is carried out, investigating the phenomena that limit the achievable values of constant inter-stage phase shift under both weak and strong coupling conditions. The gradual evolution of the system behavior with increasing coupling strength is studied. A semianalytical approach is presented for an efficient design of the oscillator array, avoiding the computational expensiveness of harmonic balance (HB) in systems with a high number of oscillator elements. The proposed method, valid for weak coupling, uses a perturbation model of the elementary oscillator obtained with HB so it is of general application to any oscillator topology with accurate descriptions of its linear and nonlinear components. Approaches for the stability and phase-noise analyses based on this formulation are also presented. The new techniques have been applied to the design of a coupled system of three oscillators at 6 GHz. The results have been successfully compared with full HB simulations and with measurements
Speech rhythm of the Danish-Chinese interlanguage relies on rhyme structure

Although speech rhythm is a highly important factor in theevaluation of nativeness, it is usually not explicitly taught insecond language acquisition. Moreover, acquisition studiesof Mandarin prosody typically focus on the acquisition oftone. We investigated durational patterns of MandarinChinese as produced by Danish learners. Native MandarinChinese rhythm is characterized by, first, sentence-finalsyllable lengthening, then tone-intrinsic duration, andfinally, rhyme structure. Danish speech rhythm isfundamentally different, since Danish is a stress languagewith only primary stress on the level of the phonologicalphrase, and extensive reduction of unstressed syllables. Weshow that the interlanguage of Danish learners of Chinese iscomparable to native Mandarin Chinese duration patternswith regard to rhyme structure. However, differentiation ofduration based on tone and final lengthening lags behind inDanish acquisition of Chinese.
Pancreatectomy using the no-touch isolation technique followed by extensive intraoperative peritoneal lavage to prevent cancer cell dissemination: a pilot study.

CONTEXT In pancreatic cancer, even for patients who have undergone curative resection (R0), survival analysis has revealed a poor survival rate due to cancer recurrence. Because the operation itself might have caused the dissemination of these cancer cells, the no-touch isolation technique and extensive intraoperative peritoneal lavage may be a potential operative procedure for improving the outcome. PATIENTS Eight patients treated by the no-touch isolation technique were compared with 10 patients treated using conventional techniques. MAIN OUTCOME MEASURES Cancer cell detection rates in the portal venous blood, frequency of recurrence, and survival rate. We also analyzed the lymphatic fluid squeezed from the resected cancerous pancreatic tissue. RESULTS In 5 out of 10 cases (50%) in the conventional procedure group, CEA mRNA was identified in the portal blood after tumor manipulation, while only 1 out of 8 cases (13%) in the no-touch isolation technique group was positive for portal CEA mRNA. All lymphatic fluid samples squeezed from the resected cancerous pancreatic tissue were positive (8/8) for CEA mRNA. The recurrence rate was 90% (9/10) in the conventional procedure group, and 38% (3/8) in the no-touch isolation technique group (P=0.043). In the conventional procedure group, hepatic metastasis, local recurrence, peritoneal dissemination, and extraabdominal recurrence were identified in 6 (60%), 4 (40%), 4 (40%), and 2 patients (20%), respectively. On the other hand, among the no-touch isolation technique group, recurrence was identified in 1 (13%), 1 (13%), 0 (0%), and 1 patient (13%), respectively. There was no peritoneal dissemination along with the decreased hepatic recurrence rate. Mean (+/-SEM) survival time was 21.2+/-5.8 months for the conventional procedure group and 41.5+/-5.6 months for the no-touch isolation technique group (P=0.018). The 3-year survival rate was 12.5+/-11.5% for the conventional procedure group and 75.0+/-21.7% for the no-touch isolation technique group. CONCLUSION This study presented the potential of cancer dissemination during the intraoperative manipulation of tumors and its contribution to cancer recurrence, as well as the significance of the no-touch isolation technique and extensive intraoperative peritoneal lavage for pancreatic cancer surgery.
