Design of Small Low-Profile Universal UHF RFID Reader Antenna

A small low-profile linearly-polarized patch antenna is proposed for universal ultra-high-frequency (UHF) RF identification (RFID) applications. The antenna is composed of a folded patch and an improved L-shaped feeding strip. It works from 834 to 970 MHz with SWR less than 2, thus the proposed antenna is universal for UHF RFID applications worldwide at the UHF band of 840-960MHz. Moreover, the air thickness of the patch antenna is 20mm, reduced to only 0. 06λ. Stable unidirectional radiation patterns, low cross-polarization level and stable gain are achieved over the pass-band.
A Bloom-Filter-based socially aware scheme for content replication in mobile ad hoc networks

The volume of mobile multimedia traffic is fast-growing, challenging the radio and backhaul network infrastructure and calling for alternative content dissemination schemes. To improve user experience and reduce infrastructure load, we exploit implicit social relationships among users and take into account content popularity, proposing push-based prefetching mechanisms which take advantage of the caching and mobile ad hoc networking capabilities of user devices. We use Bloom Filters as summaries of user caches, and design mechanisms to estimate the social distance between users and the popularity of content items, which drive our algorithms. Our simulation-based evaluation shows that our scheme brings caching performance improvements in an order of 10% in terms of absolute cache hit ratio in most of the cases studied, and from 3% to 82% in terms of normalized cache hit ratio gain.
Is Science Value Free?: Values and Scientific Understanding

Exploring the role of values in scientific inquiry, Hugh Lacey examines the nature and meaning of values, and looks at challenges to the view, posed by postmodernists, feminists, radical ecologists, Third-World advocates and religious fundamentalists, that science is value free. He also focuses on discussions of 'development', especially in Third World countries. This paperback edition includes a new preface.

Sentiment analysis for media reputation research

As a subtask of qualitative media reputa- tion research, human annotators manually encode the polarity of actors in media prod- ucts. Seeking to automate this process, we have implemented two baseline classifiers that categorize actors in newspaper articles under six and four polarity classes. Experi- ments have shown that our approach is not suitable for distinguishing between six fine- grained classes, which has turned out to be difficult for humans also. In contrast, we have obtained promising results for the four class model, through which we argue that automated sentiment analysis has a consid- erable potential in qualitative reputation re- search.
Simulations of Enhancer Evolution Provide Mechanistic Insights into Gene Regulation

There is growing interest in models of regulatory sequence evolution. However, existing models specifically designed for regulatory sequences consider the independent evolution of individual transcription factor (TF)–binding sites, ignoring that the function and evolution of a binding site depends on its context, typically the cis-regulatory module (CRM) in which the site is located. Moreover, existing models do not account for the gene-specific roles of TF-binding sites, primarily because their roles often are not well understood. We introduce two models of regulatory sequence evolution that address some of the shortcomings of existing models and implement simulation frameworks based on them. One model simulates the evolution of an individual binding site in the context of a CRM, while the other evolves an entire CRM. Both models use a state-of-the art sequence-to-expression model to predict the effects of mutations on the regulatory output of the CRM and determine the strength of selection. We use the new framework to simulate the evolution of TF-binding sites in 37 well-studied CRMs belonging to the anterior–posterior patterning system in Drosophila embryos. We show that these simulations provide accurate fits to evolutionary data from 12 Drosophila genomes, which includes statistics of binding site conservation on relatively short evolutionary scales and site loss across larger divergence times. The new framework allows us, for the first time, to test hypotheses regarding the underlying cis-regulatory code by directly comparing the evolutionary implications of the hypothesis with the observed evolutionary dynamics of binding sites. Using this capability, we find that explicitly modeling self-cooperative DNA binding by the TF Caudal (CAD) provides significantly better fits than an otherwise identical evolutionary simulation that lacks this mechanistic aspect. This hypothesis is further supported by a statistical analysis of the distribution of intersite spacing between adjacent CAD sites. Experimental tests confirm direct homodimeric interaction between CAD molecules as well as self-cooperative DNA binding by CAD. We note that computational modeling of the D. melanogaster CRMs alone did not yield significant evidence to support CAD self-cooperativity. We thus demonstrate how specific mechanistic details encoded in CRMs can be revealed by modeling their evolution and fitting such models to multispecies data.
An Ontology Roadmap for Crowdsourcing Innovation Intermediaries

Ontologies have proliferated in the last years, essentially justified by the need of achieving a consensus in the multiple representations of reality inside computers, and therefore the accomplishment of interoperability between machines and systems. Ontologies provide an explicit conceptualization that describes the semantics of the data. Crowdsourcing innovation intermediaries are organizations that mediate the communication and relationship between companies that aspire to solve some problem or to take advantage of any business opportunity with a crowd that is prone to give ideas based on their knowledge, experience and wisdom, taking advantage of web 2.0 tools. Various ontologies have emerged, but at the best of our knowledge, there isnât any ontology that represents the entire process of intermediation of crowdsourcing innovation. In this paper we present an ontology roadmap for developing crowdsourcing innovation ontology of the intermediation process. Over the years, several authors have proposed some distinct methodologies, by different proposals of combining practices, activities, languages, according to the project they were involved in. We start making a literature review on ontology building, and analyse and compare ontologies that propose the development from scratch with the ones that propose reusing other ontologies. We also review enterprise and innovation ontologies known in literature. Finally, are presented the criteria for selecting the methodology and the roadmap for building crowdsourcing innovation intermediary ontology.
Core Isolation of Critical Arrhythmia Elements for Treatment of Multiple Scar-Based Ventricular Tachycardias

Background—Radiofrequency ablation of multiple or unmappable ventricular tachycardias (VTs) remains a challenge with unclear end points. We present our experience with a new strategy isolating core elements of VT circuits. Methods and Results—Patients with structural heart disease presenting for VT radiofrequency ablation at 2 centers were included. Strategy involved entrainment/activation mapping if VT was hemodynamically stable, and voltage mapping with electrogram analysis and pacemapping. Core isolation (CI) was performed incorporating putative isthmus and early exit site(s) based on standard criteria. If VT was noninducible, the dense scar (<0.5 mV) region was isolated. Successful CI was defined by exit block (20 mA at 2 ms) within the isolated region. VT inducibility was also assessed. Forty-four patients were included (mean age, 63; 95% male; 73% ischemic cardiomyopathy; mean left ventricular ejection fraction, 31%; 68% with multiple unstable VTs [mean, 3+2]). CI area was 11+12 versus 55+40 cm2 total scar area. Additional substrate modification was performed in 27 (61%), and epicardial radiofrequency ablation was performed in 4 (9%) patients. CI was achieved in 37 (84%) and led to better VT-free survival (log rank P=0.013). Conclusions—CI is a novel strategy with a discrete and measurable end point beyond VT inducibility to treat patients with multiple or unmappable VTs. The CI region can be selected based on standard characterization of suspected VT isthmus surrogates thus limiting ablation target size. Exit block within the isolated area is achievable in most and may further improve long-term success.
Nonlinear Relationship Between Permanent and Transitory Components of Monetary Aggregates and the Economy

This paper uses several methods to study the interrelationship among Divisia monetary aggregates, prices, and income, allowing for nonstationary, nonlinearities, asymmetries, and time-varying relationships among the series. We propose a multivariate regime switching unobserved components model to obtain transitory and permanent components for each series, allowing for potential recurrent and structural changes in their dynamics. Each component follows distinct two-state Markov processes representing low or high phases. Since the lead-lag relationship between the phases can vary over time, rather than pre-imposing a structure to their linkages, the proposed flexible framework enables us to study their specific lead-lag relationship over each one of their cycles and over each U.S. recession in the last 40 years. The decomposition of the series into permanent and transitory components reveals striking results. First, we find a strong nonlinear association between the components of money and prices—all low phases of the transitory component of prices were preceded by tight transitory and permanent money phases. We also find that most recessions were preceded by tight money phases (its cyclical and permanent components) and high transitory price phases (with the exception of the 2001 and 2009-2010 recessions). In addition, all recessions were associated with a decrease in transitory and permanent income.
Boosting in English and Indonesian Research Articles: A Cross-Cultural and Cross-Disciplinary Study

Boosters, defined as linguistic devices (e.g. certainly) used by writers to indicate full commitment to the truth value of a proposition, has received little attention from applied linguists, despite their persuasive power in research writing. The present study investigated the effects of the two variables of sociocultural context and discipline on the frequency of use of boosters in research articles. A specialized corpus of 104 research articles published between 2007 and 2010 taken from applied linguistics and chemistry written in English and Indonesian by the respective native speaker scholars were quantitatively analyzed using 2 x 2 Factorial ANOVA. The results showed that there was a significant main effect of sociocultural context, F (1, 100) = 44,34, p <0,05, ŋ2 = 0,307, a significant main effect of discipline, F (1,100) = 19,16, p < 0,05, ŋ2 = 0,161, and a significant interaction between sociocultural context and discipline, F (1,100) = 6,90, p < 0,05, ŋ2 = 0,065. However, the within-sociocultural context simple effects analysis revealed that English applied linguistics and chemistry research articles were not significantly different from each other, F (1,101) = 1,07, n.s. suggesting that, discipline might not be a decisive factor that influences boosting usage in research articles. These results indicate that the two variables (sociocultural context and discipline) exerted unequal influence upon boosting practices in research articles. The differential characteristics of the two sociocultural contexts are offered as explanations to account for the differential boosting practices of English and Indonesian research articles.
Depression of Complement Regulatory Factors in Rat and Human Renal Grafts Is Associated with the Progress of Acute T-Cell Mediated Rejection

Background The association of complement with the progression of acute T cell mediated rejection (ATCMR) is not well understood. We investigated the production of complement components and the expression of complement regulatory proteins (Cregs) in acute T-cell mediated rejection using rat and human renal allografts. Methods We prepared rat allograft and syngeneic graft models of renal transplantation. The expression of Complement components and Cregs was assessed in the rat grafts using quantitative real-time PCR (qRT-PCR) and immunofluorescent staining. We also administered anti-Crry and anti-CD59 antibodies to the rat allograft model. Further, we assessed the relationship between the expression of membrane cofactor protein (MCP) by immunohistochemical staining in human renal grafts and their clinical course. Results qRT-PCR results showed that the expression of Cregs, CD59 and rodent-specific complement regulator complement receptor 1-related gene/protein-y (Crry), was diminished in the rat allograft model especially on day 5 after transplantation in comparison with the syngeneic model. In contrast, the expression of complement components and receptors: C3, C3a receptor, C5a receptor, Factor B, C9, C1q, was increased, but not the expression of C4 and C5, indicating a possible activation of the alternative pathway. When anti-Crry and anti-CD59 mAbs were administered to the allograft, the survival period for each group was shortened. In the human ATCMR cases, the group with higher MCP expression in the grafts showed improved serum creatinine levels after the ATCMR treatment as well as a better 5-year graft survival rate. Conclusions We conclude that the expression of Cregs in allografts is connected with ATCMR. Our results suggest that controlling complement activation in renal grafts can be a new strategy for the treatment of ATCMR.
Revealed Notions of Distributive Justice I – Theory # 443

We provide a framework to decompose preferences into a notion of distributive justice and a selfi shness part and to recover individual notions of distributive justice from data collected in appropriately designed experiments. “Dictator games” with varying transfer rates used in Andreoni and Miller (2002) and Fisman et al. (2007) can be used to assess individuals’ preferences, but – with the help of simple new axioms – also to recover some part of individuals’ notion of justice. “Social planner” experiments or experiments under a “veil of ignorance” (Rawls 1971) can be used to recover larger parts of the notion of justice. The axioms also allow a simple test for the validity of such an experimental approach, which is not necessarily incentivecompatible, and to recover a greater part of an individual’s preference relation in dictator experiments than before. Interpersonal comparison of the individual intensity of justice (or fairness) similar to the suggestions in Karni and Safra (2002b) are possible, and we can evaluate the intensity based on an individual’s own notion of justice. The approach is kept completely non-parametric. As such, this article is in the spirit of Varian (1982) and Karni and Safra (2002a). JEL Classifi cation: C14, C91, D11, D12, D63, D64
NF-κB/Rel-Mediated Regulation of the Neural Fate in Drosophila

Two distinct roles are described for Dorsal, Dif and Relish, the three NF-κB/Rel proteins of Drosophila, in the development of the peripheral nervous system. First, these factors regulate transcription of scute during the singling out of sensory organ precursors from clusters of cells expressing the proneural genes achaete and scute. This effect is possibly mediated through binding sites for NF-κB/Rel proteins in a regulatory module of the scute gene required for maintenance of scute expression in precursors as well as repression in cells surrounding precursors. Second, genetic evidence suggests that the receptor Toll-8, Relish, Dif and Dorsal, and the caspase Dredd pathway are active over the entire imaginal disc epithelium, but Toll-8 expression is excluded from sensory organ precursors. Relish promotes rapid turnover of transcripts of the target genes scute and asense through an indirect, post-transcriptional mechanism. We propose that this buffering of gene expression levels serves to keep the neuro-epithelium constantly poised for neurogenesis.
Locality versus Anti-locality Effects in Mandarin Sentence Comprehension

Whether the distance between the filler and the gap increases or decreases the difficulty for comprehenders has always been subject to debate. Locality theory claims that the greater the distance between the filler and the gap, the more difficult it is. However, anti-locality theory predicts that the greater the distance, the easier it is. This study examined whether it was the position of the verbs that made the differences. Three kinds of structures, simple SVO, relative clauses, and BA constructions, were manipulated. If the locality theory is correct, increasing reading times at the critical words should be observed. If anti-locality theory is correct, decreasing reading times should be found. In both SVO and RCs, we observed increasing reading times at the critical nouns. In BA constructions, however, we observed decreasing reading times at the critical verbs. It is thus the critical word at the end that leads to differences.
Data Hiding Detection Based on DWT and Zernike Moments

In this paper, we present a data hiding detection (steganalysis) method based on Zernike moments of discrete wavelet coefficients of an image and SVM. We use Zernike moments of DWT subbands coefficients of an images as features for steganalysis and use support vector machines (SVM) for classification of stego and non-stego images. Experimental results show that there are different between these features for stago and non-stego images and these features are convenient for steganalysis. With randomly selected 400 images for training and the remaining 800 images for testing, the proposed steganalysis system can achieve a correct classification rate of 98.1% for Cox et al. algorithm, 99% for Corvi watermarking algorithm and 99.2% for Zhu algorithm. For combination of algorithms we reach to 95.8% correct detection rate.
Approximating k-spanners in the LOCAL model

Graph spanners have been studied extensively, and have many applications in algorithms, distributed systems, and computer networks. For many of these application, we want distributed constructions of spanners, i.e., algorithms which use only local information. Dinitz and Krauthgamer (PODC 2011) provided a distributed approximation algorithm for 2-spanners in the LOCAL model with polylogarithmic running time, but the question of whether a similar algorithm exists for k-spanners with k > 2 remained open. In this paper, we show that a similar algorithm also works for cases where k > 2.
On greedy stream selection in MIMO BC

We consider the Broadcast Channel (BC), or in other words the multi-user (MU) downlink in a cell with a base station equipped with multiple antennas and mobile terminals equipped with a single antenna (MU-MISO case). It is well-known that user selection not only leads to multi-user diversity but also to decreased suboptimality of simple beamforming (BF) techniques compared to optimal Dirty Paper Coding (DPC) approaches. User selection by exhaustive search can be simplified to greedy approaches, in which one user gets added at a time. We review DPC-style and BF-style greedy user selection (GUS), which are developed with DPC or BF transmitters in mind. We introduce a new interpretation of the BF-style user selection criterion, which corresponds to a new approximate criterion that becomes more accurate for a large user pool. This new criterion allows interpretation and comparison of the respective roles of channel strength and orthogonality in DPC-style and BF-style selection.
Adaptive fuzzy controller design for robotic manipulators with sliding mode control

In this paper, an adaptive fuzzy sliding mode controller is proposed for a three-axis SCARA manipulator. The proposed controller possesses the advantages of adaptive control, fuzzy control, and sliding mode control. Based on the concept of sliding mode, fuzzy rules are developed to alleviate the input chattering effectively by using the developed adaptation law. The stability of the three-axis SCARA manipulator is guaranteed by using the Lyapunov method. The simulation results demonstrate that the chattering and steady state errors are eliminated and satisfactory trajectory tracking is achieved.
Flagellar Motility Is Critical for Listeria monocytogenes Biofilm Formation

ABSTRACT The food-borne pathogen Listeria monocytogenes attaches to environmental surfaces and forms biofilms that can be a source of food contamination, yet little is known about the molecular mechanisms of its biofilm development. We observed that nonmotile mutants were defective in biofilm formation. To investigate how flagella might function during biofilm formation, we compared the wild type with flagellum-minus and paralyzed-flagellum mutants. Both nonmotile mutants were defective in biofilm development, presumably at an early stage, as they were also defective in attachment to glass during the first few hours of surface exposure. This attachment defect could be significantly overcome by providing exogenous movement toward the surface via centrifugation. However, this centrifugation did not restore mature biofilm formation. Our results indicate that it is flagellum-mediated motility that is critical for both initial surface attachment and subsequent biofilm formation. Also, any role for L. monocytogenes flagella as adhesins on abiotic surfaces appears to be either minimal or motility dependent under the conditions we examined.
