A worst-case robust distributed power allocation scheme for OFDM-based cognitive radio networks

It is a complex task to allocate the secondary users' power in OFDM-based cognitive radio networks which have many sub-carriers, especially when the channel uncertainty and coupled interference exist in cognitive networks. To address the issue, a worst-case robust distributed power allocation scheme is proposed for OFDM-based cognitive radio networks in this paper. Firstly, a robust power allocation model is constructed using worst-case approach with the uncertain channel state information. A non-cooperation game framework is introduced to optimize secondary users' rate from their own profit individually with the primary user interference constraint. The variational inequality is employed to analyze the existence and uniqueness of the Nash equilibrium. The proposed scheme could optimize the power allocation under uncertain channel information and maximize secondary users' rate. And the primary user interference temperature could also be satisfied even the channel in the worst case. The simulation is presented to valid its applicability and robust in a variety of scenes.
Portable Projection-Based Augmented Reality

Advances in projection techniques have opened up projection-based augmented reality as a possible alternative to head mounted display technologies for creating augmented reality systems. This project aims to show the viability of projection-based augmented reality in a portable format. The system is constructed using OpenGL and commercially available hardware that demonstrates some limited form of interaction in three dimensions with a projected 3D object, specifically a cube. Moving forward, this could be expanded into a much richer interaction paradigm for augmented reality.
Isolation of enterohemorrhagic Escherichia coli O157 strains from patients with hemolytic-uremic syndrome by using immunomagnetic separation, DNA-based methods, and direct culture

We examined 30 children with classical hemolytic-uremic syndrome (HUS) for the presence of enterohemorrhagic Escherichia coli (EHEC) strains in stool samples and determined the specific immune response to O157 lipopolysaccharide in acute-phase serum samples from these patients. EHEC O157 strains were isolated from stool samples of 18 (60%) of the patients, and non-O157 EHEC strains were isolated from 5 (17%) of the patients. For O157 strain isolation from stools, we introduced a selective enrichment step using O157-specific antibodies attached to paramagnetic particles (immunomagnetic separation [IMS] method). This procedure allowed the detection of O157 strains at 10(2) CFU/g of stool in the presence of 10(7) coliform background flora organisms. By using IMS followed by plating on sorbitol MacConkey (SMAC) agar and cefixime-tellurite SMAC (CT-SMAC) agar, O157 strains were detected in 18 samples, whereas colony hybridization detected a subset of 12 positive samples and direct culture on CT-SMAC or SMAC agar detected only 7. Three of the 18 O157-positive stools were negative by cytotoxicity assay performed with stool filtrates and by direct PCR with DNA extracted from stools. The IMS technique allowed the isolation of O157 strains from 18 of 20 patients with serological evidence for O157 infection. Apart from the increase in sensitivity in O157 detection compared with that of direct culture, the IMS technique also has the advantage of being less labor-intensive and less time-consuming than the molecular methods. IMS can therefore be considered an efficient method for wide-spread use in the detection of O157 strains in clinical microbiology laboratories. However, because a significant number of HUS cases were attributable to non-O157 EHEC serogroups, the use of additional methods besides IMS in the bacteriological diagnosis of HUS is necessary.
Predictive Analyses of Biological Effects of Natural Products: From Plant Extracts to Biomolecular Laboratory and Computer Modeling

Year by year, the characterization of the biological activity of natural products is becoming more competitive and complex, with the involvement in this research area of experts belonging to different scientific fields, including chemistry, biochemistry, molecular biology, immunology and bioinformatics. These fields are becoming of great interest for several high-impact scientific journals, including eCAM. The available literature in general, and a survey of reviews and original articles recently published, establishes that natural products, including extracts from medicinal plants and essential oils, retain interesting therapeutic activities, including antitumor, antiviral, anti-inflammatory, pro-apoptotic and differentiating properties. In this commentary, we focus attention on interest in networks based on complementary activation and comparative evaluation of different experimental strategies applied to the discovery and characterization of bioactive natural products. A representative flow chart is shown in the paper.
Other Knowledge and Other Ways of Knowing

WHEN "CULTURE" ENTERS discourses outside our discipline-when, as Bohannan says, culture is loose on the streets-how is it used? In many ways embarrassingly like the uses we make of it inside our discipline, but with greater consequences. Culture is used selectively for that which seems most salient to the outsider, namely difference. This use gives a truncated account of what others are thinking and doing. It does not represent their grounds for action, but only those grounds that are contrastive, special for "the other," and not reasons that would hold for "us. " It thus leads to exoticizing, but more importantly to mutilating the other's point of view: representing it only partially, and therefore inadequately rendering its rationality and reasonableness. Further, in personal interaction whenever the thoughts and actions of another are interpreted as cultural, they tend to be turned into exemplars of exotic behavior. Thereby the item of behavior in question is not situated as a link in a chain of interaction between persons (to be understood and judged in communicative, social, and moral contexts); on the contrary, it is removed from the interaction and situated as a collective, stereotyped feature of groups and contrasting identities. This depersonalizes and impedes the flow of exchange and the process of convergence (Wikan 1992) in the interaction. Thirdly, "culture" is increasingly used in public debate to define an arena for contesting discourses on "identity. " Under current conditions, such discourses provide an extremely fertile field for political entrepreneurship; they allow leaders and spokesmen to claim that they are speaking on behalf of others; they allow the manipulation of media access; and they encourage the strategic construction of polarizing debates that translate into battles of influence. Such battles create hegemony and reduce options; they disempower followers and reduce the diversity of voices. Such effects of the concept of culture are contrary to most anthropologists' intentions. What might then be our best countermoves? We achieve nothing by denying the existence of power and hegemony in the world; and we turn ourselves into hostages of the undesired discourses if we merely look for faultless victims who deserve our advocacy. Our strategy must be to transcend and thus transform the debate. But no matter how often and how compellingly anthropologists arrest reification and oppose homogenization, these selfsame features seem to crop up again and again in anthropologists' own unguarded speech and thought.
Subversive stories and hegemonic tales: toward a sociology of narrative

Les AA. s'efforcent d'elaborer une sociologie de la narration. La narration est un acte social, un discours social qui depend pour sa production comme pour sa reception de normes qui definissent le lieu, le moment et la maniere par laquelle il doit etre formule. Elle est donc un discours situationnel qui depend du contexte et de l'organisation de son elaboration en ce qui concerne son effet politique. Les AA. s'attachent plus particulierement a l'etude des variables qui conditionnent soit un discours qui reproduit les relations de pouvoir soit un discours subversif
Methyl (R)-2-(2-chlorophenyl)-2-(3-nitrophenylsulfonyloxy)acetate

The reaction between methyl (R)-2-(2-chlorophenyl)-2-hydroxyacetate and 3-nitrobenzenesulfonyl chloride gave the title compound, C15H12ClNO7S, which is a promising intermediate for the synthesis of Clopidrogel, an antiplatelet drug used in the prevention of strokes and heart attacks. In the crystal, molecules are linked through C—H⋯O interactions, and there is also a short Cl⋯O contact present [Cl⋯O = 3.018 (2) Å].
Linear Recursion

We show that the full PCF language can be encoded in Lrec, a linear lambda-calculus extended with numbers, pairs and an unbounded recursor that preserves the syntactic linearity of the calculus. Thus, Lrec is a Turing complete extension of the linear lambda-calculus. We discuss evaluation strategies and implementation techniques for Lrec, exploiting the linearity of the system.
Satisfaction May Not Suffice!: A Commentary on ‘a Patient's Perspective’

Abstract There are inherent limitations in using assessments of patient satisfaction to make inferences about the quality of medical care. Such evaluations tend to be subjective, subject to reporting biases, and difficult to interpret when they are being used to motivate and guide quality improvement efforts. Newer methods of eliciting both reports and ratings from consumers, such as the Consumer Assessment of Health Plans (CAHPS) project, can provide reliable, valid, interpretable, and actionable data about selected aspects of health care. The use of these methods and continued use of new qualitative methods, such as cognitive interviewing, should allow us to continue increasing the prominence of consumer-based information in quality assessment and improvement efforts.
DXML: A High-performance Scientific Subroutine Library

Mathematical subroutine libraries for science and engineering applications are an important tool in high-performance computing. By identifying and optimizing frequently used, numerically intensive operations, these libraries help in reducing the cost of computation, enhancing portability, and improving productivity. The Digital eXtended Math Library is a set of public domain and Digital proprietary software that has been optimized for high performance on Alpha systems. In this paper, DXML and the issues related to library software technology are described. Specific examples illustrate how algorithms can be optimized to take advantage of the architecture of Alpha systems. Modern algorithms that effectively exploit the memory hierarchy enable DXML routines to provide substantial improvements in performance.
Potential Applications of Polymeric Microsphere Suspension as Subcutaneous Depot for Insulin

Abstract The objective of this investigation was to develop an injectable, depot-forming drug delivery system for insulin based on microparticle technology to maintain constant plasma drug concentrations over prolonged period of time for the effective control blood sugar levels. Formulations were optimized with two well-characterized biodegradable polymers namely, poly(dl-lactide-co-glycolide) and poly-ε-caprolactone and evaluated in vitro for physicochemical characteristics, drug release in phosphate buffered saline (pH 7.4), and evaluated in vivo in streptozotocin-induced hypoglycemic rats. With a large volume of internal aqueous phase during w/o/w double emulsion solvent evaporation process and high molecular weight of the polymers used, we could not achieve high drug capture and precise control over subsequent release within the study period of 60 days. However, this investigation revealed that upon subcutaneous injection, the biodegradable depot-forming polymeric microspheres controlled the drug release and plasma sugar levels more efficiently than plain insulin injection. Preliminary pharmacokinetic evaluation exhibited steady plasma insulin concentration during the study period. These formulations, with their reduced frequency of administration and better control over drug disposition, may provide an economic benefit to the user compared with products currently available for diabetes control.
Olfactory Cues from Plants Infected by Powdery Mildew Guide Foraging by a Mycophagous Ladybird Beetle

Powdery mildews (Erysiphales) are economically important plant pathogens that attack many agricultural crops. Conventional management strategies involving fungicide application face challenges, including the evolution of resistance and concerns over impacts on non-target organisms, that call for investigation of more sustainable alternatives. Mycophagous ladybird beetles (Coleoptera: Coccinellidae) feed on powdery mildew and have considerable potential as biological control agents; however, the foraging ecology and behavior of these beetles is not well understood. Here we document the olfactory cues presented by squash plants (Cucurbita moschata) infected by powdery mildew (Podosphaera sp.) and the behavioral responses of twenty-spotted ladybird beetles (Psyllobora vigintimaculata) to these cues. Volatile analyses through gas chromatography revealed a number of volatile compounds characteristic of infected plants, including 3-octanol and its analogues 1-octen-3-ol and 3-octanone. These compounds are typical “moldy” odorants previously reported in volatiles collected from other fungi. In addition, infected plants exhibited elevated emissions of several compounds also observed in collections from healthy leaves, including linalool and benzyl alcohol, which are reported to have anti-fungal properties. In Y-tube choice assays, P. vigintimaculata beetles displayed a significant preference for the odors of infected plants compared to those of healthy plants. Moreover, beetles exhibited strong attraction to one individual compound, 1-octen-3-ol, which was the most abundant of the characteristic fungal compounds identified. These results enhance our understanding of the olfactory cues that guide foraging by mycophagous insects and may facilitate the development of integrated disease-management strategies informed by an understanding of underlying ecological mechanisms.
Representation and Recognition of Events in Surveillance Video Using Petri Nets

Detection of events is an essential task in surveillance applications. This task requires finding a general event representation method and developing efficient recognition algorithms dealing with this representation. In this paper, we describe an interactive system for querying surveillance video about events. The queries may not be known in advance and have to be composed from primitive events and previously defined queries. We propose using Petri nets as both representation and recognition methods. The Petri net representation for users' queries is derived automatically from simpler event nets. Recognition is then performed by tokens moving through the Petri nets.
Capturing social and cultural influences: relating individual work-life experiences to context

As Anatole France suggests, education is a phenomenon that involves self-reflection to qualify what one knows and still does not know. One of the most valued rituals and social experiences of scholars is the gathering together at conferences to share perspectives. From 2013 to 2015, I served as the first elected President of the Work Family Researchers Network (WFRN) and Program Chair of an international conference held in June 2014 in New York City with over 200 sessions and 42 countries represented. This special issue reflects a partnership with the journal Community, Work & Family to capture conference highlights. Below I give a brief overview of papers and the future challenges I called for in the WFRN Presidential address to move work-life research from the margins to the mainstream (Kossek, 2014). As you read this introduction, consider how the issues noted might motivate your next study to focus on under-examined and meaningful questions in our field. While each paper helps to advance understanding of cultural and contextual issues, many gaps remain. Like the work-family field, the WFRN conference was a rich dynamic experience including researchers, practitioners and policy-makers from around the globe. Participants shared viewpoints on what they ‘know’ are truths from their ideographic vantage point with colleagues from other cultures and disciplinary perspectives to fill in and make salient though scholarly interactions – how much they still do not know (and have yet to learn).
Interpolation of missing data values for audio signal restoration using a Gabor regression model

We present a method to address the (inherently ill-posed) problem of missing data interpolation over repeated short gaps in audio signals. By formulating the problem in terms of a Gabor regression model, we show that it is possible to leverage information from the surrounding time-frequency plane in order to obtain an interpolation in keeping with the qualities of the signal under consideration. As an exploratory investigation of this technique's potential, we consider two example restoration scenarios in which over one third of the data values in total are missing.
A Method for Automated Testing of Software Interface

Programinės įrangos testavimas yra brangiausia programinės įrangos kūrimo proceso dalis, kuriai tenka daugiau kaip 50% isteklių. Siandien dauguma programinės įrangos turi grafine vartotojo sąsają. Todėl programinė įranga paprastai testuojama per vartotojo sąsają. Siekiant sumažinti testavimo sąnaudas ir kuo issamesniau atlikti programinės įrangos testavimą, testavimo pro-cesas turi būti automatizuotas. Automatizavimas apima testų paruosimą, vykdymą ir rezultatų patikrinimą. Dauguma esamų testavimo metodų yra orientuoti tik į kai kurių testavimo etapų bet ne į viso proceso automatizavimą. Siame darbe pateikiamas testų modeliu grindžiamas programinės įrangos automatizuotojo testavimo per vartotojo sąsają metodas, orientuotas į visų testavimo etapų automatizavimą. http://dx.doi. org/10.5755/j01.itc. 40.2. 424
Towards high quality text entry on smartwatches

Smartwatches now provide users with access to many applications on smartphones direct from their wrists, without the need to touch their smartphone. While applications such as email, messaging, calendar and social networking provide views on the watch, there is normally no text entry method so users cannot reply on the same device. Here we introduce requirements for smartwatch text entry, an optimised alphabetic layout and present a prototype implementation together with preliminary user feedback. While raising some problems, the feedback gives indicates that reasonable quality and speed is achievable on a smartwatch and encourages our future work.
Speaker tracking in reverberant environments using multiple directions of arrival

Accurate estimation of the Direction of Arrival (DOA) of a sound source is an important prerequisite for a wide range of acoustic signal processing applications. However, in enclosed environments, early reflections and late reverberation often lead to localization errors. Recent work demonstrated that improved robustness against reverberation can be achieved by clustering only the DOAs from direct-path bins in the short-term Fourier transform of a speech signal of several seconds duration from a static talker. Nevertheless, for moving talkers, short blocks of at most several hundred milliseconds are required to capture the spatio-temporal variation of the source direction. Processing of short blocks of data in reverberant environment can lead to clusters whose centroids correspond to spurious DOAs away from the source direction. We therefore propose in this paper a novel multi-detection source tracking approach that estimates the smoothed trajectory of the source DOAs. Results for realistic room simulations validate the proposed approach and demonstrate significant improvements in estimation accuracy compared to single-detection tracking.
Appearance-Related Communication and Body Image Outcomes: Fat Talk and Old Talk Among Mothers and Daughters

ABSTRACT The current study sought to investigate mothers’ and daughters’ appearance-related communication and its relation to body image outcomes. Participants included 199 mother-daughter dyads that completed online questionnaires containing measures of fat talk, old talk, body dissatisfaction, body surveillance, drive for thinness, and bulimic tendencies. Actor-partner interdependence models revealed that (a) mothers’ and daughters’ fat talk, but not old talk, were significantly related to one another, (b) mothers’ and daughters’ fat talk and old talk were significantly related to their own body image outcomes, (c) mothers’ fat talk was positively related to daughters’ bulimic tendencies, and (d) mothers’ old talk was positively related to daughters’ body dissatisfaction. These results suggest that engaging in appearance-related communication is problematic for the person making the comments and, to some extent, being exposed to another person’s appearance-related comments can be harmful to the individual as well—at least for the daughters in the current sample.
Fortuitous Brand Image Transfer

This study investigates the phenomenon of fortuitous brand image transfer, or image transfer that occurs by chance, between two brands sponsoring the same event concurrently (i.e., concurrent sponsorships). Two experiments show that concurrent sponsorships lead either to a transfer of image or to a contrast of image between sponsoring brands that are both familiar, depending on the similarity of their underlying brand concept. Image transfer occurs when the brand concepts of the two sponsors are similar, whereas image contrast occurs when the two sponsors have dissimilar brand concepts. Implications for branding and sponsorship research are provided, as well as recommendations for managers. Finally, directions for further research are suggested.
A Theory of Deep Stratification and Overturning Circulation in the Ocean

Abstract A simple theoretical model of the deep stratification and meridional overturning circulation in an idealized single-basin ocean with a circumpolar channel is presented. The theory includes the effects of wind, eddies, and diapycnal mixing; predicts the deep stratification in terms of the surface forcing and other problem parameters; makes no assumption of zero residual circulation; and consistently accounts for the interaction between the circumpolar channel and the rest of the ocean. The theory shows that dynamics of the overturning circulation can be characterized by two limiting regimes, corresponding to weak and strong diapycnal mixing. The transition between the two regimes is described by a nondimensional number characterizing the strength of the diffusion-driven compared to the wind-driven overturning circulation. In the limit of weak diapycnal mixing, deep stratification throughout the ocean is produced by the effects of wind and eddies in a circumpolar channel and maintained even in the .
