Adaptive Relay Selection for Regenerative OFDMA Relay Networks with Fairness Constraints

We propose an adaptive relay selection scheme for a regenerative orthogonal frequency division multiplexing access (OFDMA) relay network with fairness constraints. The proposed scheme selects the best M relays out of a set of K potential relays to maximize the system capacity. Among these selected relays, subcarriers are reallocated to satisfy fairness constraints as well as to minimize the decrease of the system capacity. The simulation results show that the proposed scheme achieves significant performance improvement over direct transmission and opportunistic relaying with OFDM (OR-OFDM). In addition, multiuser diversity is achieved as the number of potential relays increases with proposed scheme.
Patient Comorbidities and Complications After Spinal Surgery: A Societal-Based Cost Analysis

Study Design. Prospective observational study. Objective. To determine how patient comorbidities and perioperative complications after spinal surgery affect the health care costs to society. Summary of Background Data. Despite efforts to reduce adverse events related to spinal surgery, complications are common and significantly increased by patient comorbidities. Methods. Patients who underwent spinal surgery at a tertiary academic center during a 6-month period (May 2008 to December 2008) were prospectively followed. All demographic data, comorbidities, procedural information, and complications to 30-day follow-up were recorded. Diagnosis-Related Group codes and Current Procedural Terminology codes were captured for each patient. Direct costs were estimated from a societal perspective, using 2008 Medicare rates of reimbursement. A multivariable analysis was performed to assess the impact of specific patient comorbidities and complications on total health care costs. Results. A total of 226 cases were analyzed. The mean cost of care for cases with complications was greater than that for cases without complications ($13,518.35 [95% confidence interval (CI), $9378.80–$17,657.90]; P < 0.0001). These results were consistent across degenerative, traumatic, and tumor/infection preoperative diagnoses. Cases with major complications were more costly than those with minor complications ($13,714.88 [CI, $6353.02–$21,076.74]; P = 0.0001). Systemic malignancy and preoperative neurological comorbidity were each associated with an increase in the cost of care ($7919 [CI, $2073–$15,225]; P = 0.006] and $5508 [CI, $814–$11,198; P = 0.02]), respectively, when compared with a baseline cost of care derived from all cases in the database. The cost of care was increased by pulmonary complications ($7233 [CI, $3982.53–$11,152.88]; P < 0.0001), instrumentation malposition ($6968 [CI, $1705.90–$14,277.16]; P = 0.0062), new neurological deficit ($4537 [CI, $863.95–$9274.30]; P = 0.013), and by wound infection ($4067 [CI, $1682.79–$6872.39]; P = 0.0004), after adjustment for covariates. Conclusion. Both minor and major complications were found to increase the cost of care in a prospective assessment of spine surgery complications. Specific patient comorbidities and perioperative complications are associated with significant increases in the total cost of care to society.

BUPT_PRIS at TREC 2014 Knowledge Base Acceleration Track

Abstract : This paper describes the system in Vital Filtering and Streaming Slot Filling task of TREC 2014 Knowledge Base Acceleration Track. In the Vital Filtering task, The PRIS system focuses attention on query expansion and similarity calculation. The system uses DBpedia as external source data to do query expansion and generates directional documents to calculate similarities with candidate worth citing documents. In the Streaming Slot Filling task, The BUPT_PRIS system utilizes a pattern learning method to do relation extraction and slot filling. Patterns of regular slots which mostly are same to TAC-KBP slots are learned from KBP Slot Filling corpus. Other slots are manually picked up some training seeds for those slot types that KBP didn't contain to use bootstrapping method.
PPCea: A Domain-Specific Language for Programmable Parameter Control in Evolutionary Algorithms

An Evolutionary Algorithm (EA) is a meta-heuristic and stochastic optimization search process that mimics Darwinian evolution theory and Mendel's Genetics. Each process facilitates (a) population(s) evolve into fittest and/or convergence by setting parameters of selection, mutation, crossover, population resizing, and/or many other variant operators. However, due to two primary identified factors, EAs are still a challenging research topic: (1) Value choices/ranges for parameters (i.e., parameter settings) will greatly influence the evolution performance of a search process in terms of fittest and/or convergence; and (2) Parameter settings that are good for one fitness function do not guarantee the same evolution performance of another fitness function. Namely, parameter settings are function-specific. Different functions may have various characteristics that request specific attention. In order to better organize and overcome the parameter setting problem, Eiben et al. have classified parameter settings into parameter tuning and parameter control (Eiben et al., 1999): Parameter tuning determines parameter values before a search process begins while parameter control changes parameter values during a search process. More specifically, parameter control adjusts parameters on-the-fly using three different approaches: (1) Deterministic approach alters parameters based on certain pre-determined rules or formulae; (2) Adaptive approach strategically adjusts parameter values based on the feedbacks of a search process. Such feedbacks could be fitness, diversity, distance, among others; and (3) Self-adaptive approach encodes parameters to be adapted and evolves them along with a search process. Yet, even with such a classification, to our best knowledge there is no existing tool to assist researchers with conducting experiments of parameter settings with ease. Namely, researchers need to find out appropriate places out of thousand lines of EA source code to introduce and update specific parameters (including feedbacks) as well as formulae and adaptive strategies. Additionally, a number of revisions for EA source code will be also required for different kinds of experiments. To EA experimenters, such endeavor is time consuming and error prone. To EA developers, complex and tangling source code, resulted from different
Species-Specificity of Endogenous Pyrogen in Serum.∗

Summary Endogenous serum pyrogen from rabbits produced fever in dogs and vice versa. Pyrogenicity of EP in the homologous species was dose related, but this was not the case in the heterologous species. Human serum obtained from patients both during fever and after defervescence produced fever in rabbits. These results suggest that pyrogenicity of EP in animals of different species is probably a non-specific phenomenon.
Euchromatin and Pericentromeric Heterochromatin: Comparative Composition in the Tomato Genome

Eleven sequenced BACs were annotated and localized via FISH to tomato pachytene chromosomes providing the first global insights into the compositional differences of euchromatin and pericentromeric heterochromatin in this model dicot species. The results indicate that tomato euchromatin has a gene density (6.7 kb/gene) similar to that of Arabidopsis and rice. Thus, while the euchromatin comprises only 25% of the tomato nuclear DNA, it is sufficient to account for ∼90% of the estimated 38,000 nontransposon genes that compose the tomato genome. Moreover, euchromatic BACs were largely devoid of transposons or other repetitive elements. In contrast, BACs assigned to the pericentromeric heterochromatin had a gene density 10–100 times lower than that of the euchromatin and are heavily populated by retrotransposons preferential to the heterochromatin—the most abundant transposons belonging to the Jinling Ty3/gypsy-like retrotransposon family. Jinling elements are highly methylated and rarely transcribed. Nonetheless, they have spread throughout the pericentromeric heterochromatin in tomato and wild tomato species fairly recently—well after tomato diverged from potato and other related solanaceous species. The implications of these findings on evolution and on sequencing the genomes of tomato and other solanaceous species are discussed.
The Effects of the Transition to Parenthood and Subsequent Children on Men’s Well-Being and Social Participation

This study uses data (N = 3,088) from the first two waves of the National Survey of Families and Households to explore the effects of the transition to fatherhood and the addition of subsequent children on men’s psychological and physical health, contacts with extended family, social interactions, and work behaviors. The results sugget that new children lead to changes in men’s well-being and social participation, but the effects are conditioned by the structural context of fatherhood and men’s initial fatherhood status. Overall, the evidence indicates that the transition to parenthood and the addition of subsequent children primarily transform the organization of men’s lives, especially when they become coresident fathers. Men making the transition to parenthood are most likely to be affected. Fatherhood encourages men to increase intergenerational and extended family interactions, participation in service-oriented activities, and hours in paid labor—at the expense of spending time socializing.
RELACIÓN ENTRE EL PENSAMIENTO CREATIVO Y EL EJERCICIO FÍSICO EN PERSONAS ADULTAS

The purpose of this study was to analyze the relationship between the amount of physical exercise and type of exercise that makes a person narrative creativity. Participants in the study were 40 adults in the city of Malaga (Spain), aged between 22 and 55 years (M = 32.95, SD = 9.07). The amount of physical activity was measured by the World Physical Activity Questionnaire (IPAQ) and the Test of Creative Imagination (PIC-A) was used to evaluate the narrative creativity. The obtained data were evaluated with SPSS v18.0. The correlation analysis and linear regression carried out revealed relationships between variables of physical exercise and creativity being the most significant vigorous exercise (r² = 0.56, p < .001). In conclusion both vigorous exercise, such as the total amount exercise were positively correlated with higher rates of narrative creativity.
On the design of interfaces to sparse direct solvers

We discuss the design of general, flexible, consistent, reusable, and efficient interfaces to software libraries for the direct solution of systems of linear equations on both serial and distributed memory architectures. We introduce a set of abstract classes to access the linear system matrix elements and their distribution, access vector elements, and control the solution of the linear system. We describe a concrete implementation of the proposed interfaces, and report examples of applications and numerical results showing that the overhead induced by the object-oriented design is negligible under typical conditions of usage. We include examples of applications, and we comment on the advantages and limitations of the design.
Impact of Firms Strategic Predisposition on Consumers Perceived Value of Green Products

This study aims to investigate firms’ strategic predisposition and its impact on perceived value towards green products. The model comprises strategic predisposition, perceived value and green products. A purposive sampling has been proposed which accounts for 50 knowledgeable respondents both working professionals and laymen (users of designated products). All the constructs in the constituted model have been tested using a five point likert scale developed by the researcher subject to preliminary and post interviews followed pilot testing. The data has been analyzed using descriptive statistics as well as Regression, and One Way ANOVA. The study has concluded that given the strategic predisposition of firms, strong perceived value could contribute in having green products. Furthermore, perceived value can be positively formed when firms pursue strategic predisposition about environmentalism. The presence of such strategic actions tends to form positive relationship between the independent variables and the dependent variable also implies two way (firms & consumers) readiness.
Dynamic Reconfiguration in Planetary Exploration: A Sociomaterial Ethnography

In taking into account the ways in which material and social realms are constitutively entangled within organizations, it is rhetorically tempting to say that technologies and social structures reconfigure each other. But what does it mean to reconfigure? How does one "figure" the other and how do we fully embrace a mutually constitutive relationship when examining fluid relations? This paper delves into these questions by exploring how physical, social, material, technological, and organizational arrangements dynamically reconfigure each other in the duration of organizational practice. Using the venue of space exploration, we present three empirical examples from an ethnographic engagement with a NASA mission orbiting an outer planet in the solar system to examine various configurations and sociomaterial relations. In this endeavor, we suggest that theoretical and empirical traction can be gained by focusing attention on the dynamic reconfigurations between social and material realms. In so doing, we call attention to the ways in which current sociomaterial perspectives have difficulty articulating the shifting, figural, asymmetric and dynamic negotiations between people, social structures, information technologies, and representational objects. This paper contributes to current discussions of sociomaterial relations in information systems research by presenting an empirical treatment of entangled and shifting reconfigurations and providing language for engaging with this perspective.
Poly(A) Tail Length-dependent Stabilization of GAP-43 mRNA by the RNA-binding Protein HuD*

The neuronal ELAV-like RNA-binding protein HuD binds to a regulatory element in the 3′-untranslated region of the growth-associated protein-43 (GAP-43) mRNA. Here we report that overexpression of HuD protein in PC12 cells stabilizes the GAP-43 mRNA by delaying the onset of mRNA degradation and that this process depends on the size of the poly(A) tail. Using a polysome-basedin vitro mRNA decay assay, we found that addition of recombinant HuD protein to the system increased the half-life of full-length, capped, and polyadenylated GAP-43 mRNA and that this effect was caused in part by a decrease in the rate of deadenylation of the mRNA. This stabilization was specific for GAP-43 mRNA containing the HuD binding element in the 3′-untranslated region and a poly(A) tail of at least 150 A nucleotides. In correlation with the effect of HuD on GAP-43 mRNA stability, we found that HuD binds GAP-43 mRNAs with long tails (A150) with 10-fold higher affinity than to those with short tails (A30). We conclude that HuD stabilizes the GAP-43 mRNA through a mechanism that is dependent on the length of the poly(A) tail and involves changes in its affinity for the mRNA.
Role of protein kinase C in angiotensin II-induced constriction of renal microvessels.

UNLABELLED Role of protein kinase C in angiotensin II-induced constriction of renal microvessels. BACKGROUND Although angiotensin II (Ang II) exerts its action through multiple vasomotor mechanisms, the contribution of phosphoinositol hydrolysis products to Ang II-induced renal vasoconstriction remains undetermined. METHODS The role of protein kinase C (PKC) in Ang II-induced afferent (AFF) and efferent (EFF) arteriolar constriction was examined using the isolated perfused hydronephrotic rat kidney. RESULTS Ang II (0.3 nmol/L)-induced EFF constriction was refractory to inhibition of voltage-dependent calcium channels by pranidipine (1 micromol/L, 19 +/- 2% reversal) but was completely reversed by a PKC inhibitor, chelerythrine (1 micromol/L, 96 +/- 2% reversal). Furthermore, direct PKC activation by phorbol myristate acetate (PMA; 1 micromol/L) caused prominent EFF constriction, and this constriction was inhibited by manganese and free calcium medium. In contrast, Ang II-induced AFF constriction was completely abolished by pranidipine (98 +/- 4% reversal) and was partially inhibited by chelerythrine (55 +/- 3% reversal). Although PMA elicited marked AFF constriction, this constriction was insensitive to the calcium antagonist, but was totally inhibited by manganese or free calcium medium. CONCLUSIONS PKC plays an obligatory role in Ang II-induced EFF constriction that requires extracellular calcium entry through nonselective cation channels. In contrast, in concert with our recent findings demonstrating a complete dilation by thapsigargin, Ang II-induced AFF constriction is mainly mediated by inositol trisphosphate (IP3) and voltage-dependent calcium channel pathways, but could not be attributed to the PKC-activated calcium entry pathway (for example, nonselective cation channels). Rather, Ang II-stimulated PKC may cross-talk to the IP3/voltage-dependent calcium channel pathway and could modulate the vasoconstrictor mechanism of the AFF. Thus, the role of PKC during Ang II stimulation differs in AFF and EFF, which may constitute segmental heterogeneity in the renal microvasculature.
Enhanced Energy harvesting, utilizing ZnO nanosheet based nanogenerator embedded in phononic crystal

In this report, we present a direct current piezoelectric nanogenerator based on ZnO nanosheets, which is driven by ultrasound waves propagating in water. ZnO nanosheets have been grown by hydrothermal method on Al layer as the bottom ohmic contact, while Ni layer serves as the top Schottky contact. Then, we have designed a 1D phononic crystal to realize localized standing wave at the position of nanogenerator , and consequently enhance the energy harvesting performance. The proposed phononic crystal consists of water/steel periodic slabs which are enclosing both sides of the nanogenerator, and the created mid-gap state is matched with the source frequency in the designed structure. Our simulation results confirm that the pressure difference exerted to the nanogenerator is enhanced by a factor of about 12.3, in comparison with the pristine ZnO nanogenerator.
Force plate gait analysis at the walk and trot in dogs with low-grade hindlimb lameness

Summary Objective: To evaluate the accuracy of force plate gait analysis at the walk and trot in dogs with low-grade hindlimb lameness. Material and methods: Nineteen healthy dogs and 41 dogs with low-grade unilateral hindlimb lameness due to stifle or hip joint problems were walked and trotted over a force plate. Peak vertical forces (PVF) were recorded, and a symmetry index (SI) was calculated from the PVF of the hindlimbs. ‘Cut-off’ values were determined from the SI of the normal dogs. These cut-off values were used to discriminate lame dogs from normal ones. Sensitivity and specificity were evaluated for measurements at walk and trot, and the Cohen’s Kappa coefficient (k) was used to determine the agreement between clinical lameness and force plate measurements, and between force plate results at walk and trot. Receiver Operating Characteristics (ROC) curve were plotted for both gaits to evaluate accuracy. Results: The sensitivity of the measurements at walk was 0.63, and specifity was 0.95. The sensitivity of the measurements at trot was 0.90, and specificity was 1.0. Moderate agreement was found between force plate measurements at walk and trot, and between clinical gait assessment and force plate measurements at walk. Good agreement was found between clinical gait assessment and measurements at trot. ROC analyses revealed the trot (94.7% [91.7%; 97.7%]) to be the more accurate test than the walk (85.0% [80.1%; 89.9%]). Conclusion: The trotting gait was more sensitive and accurate than the walking gait for the differentiation of dogs with a low-grade hindlimb lameness from normal ones using force plate gait analysis.
Making Molehills Out of Molehills: Reply to Lawrence Stedman's Review of The Manufactured Crisis

Berliner and Biddle answer Lawrence Stedman's review of their book The Manufactured Crisis, which was published in the Education Policy Analysis Archives as Volume 4, Number 1, 1996. Throughout his term as founding editor of "Contemporary Psychology," Edwin G. Boring insisted that the basic tasks of the responsible reviewer are to portray with honesty the intentions of authors and to assess carefully whether those intentions are realized in their writings. Unfortunately, Lawrence Stedman (1996) does not honor such laudable tenets in his so-called "review" of our book, THE MANUFACTURED CRISIS, appearing in Education Policy Analysis Archives, 4(1). Instead, Stedman chooses to ignore both the intentions that we stated clearly in our book and the vast bulk of what we actually wrote about in its eight chapters. Worse, he asserts falsely that our book was based on four "sweeping claims" and then attacks us because the analyses with which we supposedly supported these claims were "deeply flawed and misleading.
