On secure and reliable communications in wireless sensor networks: Towards k-connectivity under a random pairwise key predistribution scheme

We study the secure and reliable connectivity of wireless sensor networks. Security is assumed to be ensured by the random pairwise key predistribution scheme of Chan, Perrig, and Song, and unreliable wireless links are represented by independent on/off channels. Modeling the network by an intersection of a random K-out graph and an Erdös-Rényi graph, we present scaling conditions (on the number of nodes, the scheme parameter K, and the probability of a wireless channel being on) such that the resulting graph contains no node with degree less than k with high probability, when the number of nodes gets large. Results are given in the form of a zero-one law and are shown to improve the previous results by Yağan and Makowski on the absence of isolated nodes (i.e., absence of nodes with degree zero). Via simulations, the established zero-one laws are shown to hold also for the property of k-connectivity; i.e., the property that graph remains connected despite the deletion of any k - 1 nodes or edges.
Numb regulates somatic cell lineage commitment during early gonadogenesis in mice

During early gonadogenesis, proliferating cells in the coelomic epithelium (CE) give rise to most of the somatic cells in both XX and XY gonads. Previous dye-labeling experiments showed that a single CE cell could give rise to additional CE cells and to both supporting and interstitial cell lineages, implying that cells in the CE domain are multipotent progenitors, and suggesting that an asymmetric division is involved in the acquisition of gonadal cell fates. We found that NUMB is asymmetrically localized in CE cells, suggesting that it might be involved. To test this hypothesis, we conditionally deleted Numb on a Numbl mutant background just prior to gonadogenesis. Mutant gonads showed a loss of cell polarity in the surface epithelial layers, large interior cell patches expressing the undifferentiated cell marker LHX9, and a loss of differentiated cells in somatic cell lineages. These results indicate that NUMB is necessary for establishing polarity in CE cells, and that asymmetric divisions resulting from CE polarity are required for commitment to differentiated somatic cell fates. Surprisingly, germ cells, which do not arise from the CE, were also affected in mutants, which may be a direct or indirect effect of loss of Numb. Highlighted article: Numb establishes cell polarity in the gonadal coelomic epithelium and is required for asymmetric cell division and somatic cell fate specification during gonadogenesis.
OPTICAL COHERENCE TOMOGRAPHY CHARACTERISTICS IN EYES WITH OPTIC PIT MACULOPATHY

Purpose: To study the optical coherence tomography characteristics of optic pit maculopathy and propose the anatomical pathophysiology of fluid conduit from pit to macula. Methods: The charts of 32 patients (32 eyes) with the diagnosis of optic pit maculopathy were reviewed. Clinical variables that were studied included duration of visual impairment, initial visual acuity, and associated fundus features. Optical coherence tomography characteristics including communication with pit, layer of retina involved in schisis, and presence of subretinal fluid were noted. Results: The mean age of the patients was 27.8 years, and the mean duration of visual impairment was 21.8 months. Seventeen eyes (53.12%) had combined outer and inner layer schisis with subretinal fluid, whereas 12 eyes (37.5%) presented with outer layer schisis and subretinal fluid. Two eyes (6.25%) had outer layer schisis only, and only 1 eye (3.12%) presented with schisis of both inner and outer layers only. Conclusion: The authors propose a possible pathway of fluid movement in optic pit maculopathy: fluid first seeps into the outer retinal layer and then involves the other layers.
Egrule vs. Ruleg Teaching: A Replication

In an earlier study into learning by discovery, the variables of school grade and intelligence were investigated. This partial replication using a map-reading task consisted of a 2 X 2 X 2 factorial design involving instructional method (egrule and ruleg), school grade (grades 9 and 5), and intelligence (high and average). A set of eight dependent variables was used. Similar results were obtained from both studies and are discussed with respect to other recent findings.
Automatic Derivation of a Phoneme Set with Tone Information for Chinese Speech Recognition Based on Mutual Information Criterion

An appropriate approach to model tone information is helpful for building Chinese large vocabulary continuous speech recognition system. We propose to derive an efficient phoneme set of tone-dependent sub-word units to build a recognition system, by iteratively merging a pair of tone-dependent units according to the principle of minimal loss of the mutual information. The mutual information is measured between the word tokens and their phoneme transcriptions in a training text corpus, based on the system lexical and language model. The approach has the capability to keep discriminative tonal (and phoneme) contrasts that are most helpful for disambiguating homophone words due to lack of tones, and merge those tonal (and phoneme) contrasts that are not important for word disambiguation for the recognition task. This enable a flexible selection of phoneme set according to a balance between the MI information amount and the number of phonemes. We applied the method to traditional phoneme set of initial/finals, and derived several phoneme sets with different number of units. Speech recognition experiments using the derived sets showed their effectiveness
Lived experiences

In the popular discourse, ‘arranged marriage’ and ‘love marriage’ are assumed to be radically opposed forms of conjugal union, associated with equally polarised responses from the natal kin—approval and encouragement for the former and the opposite for the latter. This article critically examines the lived experiences of ‘arranged marriages’ and ‘love marriages’ among working–class women in Delhi in order to show how, in practice, conjugal relations, in both instances, elicit complex and heterogeneous responses from natal kin. The article highlights the role of emotional, material and practical support provided by the primary natal kin to their married daughters in shaping women's relationship with their husbands and affines. Using ethnographic methods to study the dynamics of married couples’ everyday marital conflicts in slums and low–income resettlement colonies in Delhi, this research makes a case for a deeper and more nuanced understanding of contemporary natal kin support structures, mother–daughter bonds and spousal intimacy in urban north India.
Complainers versus non-complainers: a multi-national investigation of individual and situational influences on customer complaint behaviour

Abstract One of the least understood areas in customer complaint behaviour (CCB) research is why some customers complain and others do not in similar dissatisfaction situations. Prior research has explored differences in customer characteristics between complainers and non-complainers, but not in association with relevant situational factors. This gap is addressed with a new conceptual framework incorporating two situational variables – customer dissatisfaction and involvement – and two consumer traits – impulsivity and self-monitoring. Several hypotheses about their main and interaction effects are tested in two different contexts, using a survey-based study in three countries (Singapore, South Korea, and the United States). Specifically, it is shown that CCB is positively associated with involvement and impulsivity, and negatively with self-monitoring. Involvement and impulsivity are shown to moderate the association between dissatisfaction and CCB positively, and self-monitoring moderates it negatively. Some implications and directions for future research are also discussed.
The Interaction of Attraction and Selection: Implications for College Recruitment and Schneider's ASA Model

Les jeunes qui viennent d’obtenir leur premier diplome universitaire (≪college≫) constituent un potentiel important de candidats a l’embauche dans les grandes entreprises. Les responsables des organisations ont besoin de savoir en quoi les profils de ces futurs diplomes susceptibles d’etre attires et selectionnes par l’organisation se differencient des profils de la population generale des candidats. Nous avons, dans cette recherche, etudie la relation existant entre les profils de 223 etudiants sur le point d’obtenir leur diplome du ≪college≫ et l’attirance pour une organisation, l’obtention d’un score satisfaisant a une procedure de selection et l’interaction de ces deux variables. Les resultats montrent que ceux qui sont attires par l’organisation different de ceux qui ne le sont pas. Ceux qui seraient retenus pour la poursuite du recrutement sont differents de ceux qui seraient elimines. Mais l’interaction de l’attirance et de la selection n’est en rapport avec aucune des differences individuelles. En outre, l’attirance et la selection n’interagissent pour reduire la variance sur aucune des variables de differences individuelles. Ces resultats ouvrent une nouvelle perspective sur les consequences modelisees dans le schema Attirance-Selection-Elimination de B. Schneider (1987). On discute enfin des implications de notre recherche pour ce modele et pour le recrutement des etudiants de ≪college≫. New college graduates are an important source of hires in large firms. Of interest to organisational decision makers are how the individual-difference profiles of soon-to-be college graduates that are likely to be attracted to, and selected by, the organisation compare with the profiles of the overall applicant population. In this research, we investigated how self-reported attraction to an organisation, achievement of a passing score on an organisation's screening device, and the interaction of these two variables related to the individual-difference profiles of 223 senior-level college undergraduates. Results indicated that those who were attracted to the organisation differed from those who were not attracted. Those who would be screened in for further selection by the organisation differed from those who would be rejected. However, the interaction of attraction and screening was unrelated to any of the individual differences. Moreover, attraction and screening did not interact to restrict variance on any of the individual-difference variables. These results provide a new perspective on the effects hypothesised in B. Schneider's (1987) Attraction-Selection-Attrition model. Implications for this model and for recruiting from the college student population are discussed.
ANALYSIS OF THE ASSESSMENT OF CALORIC EXPENDITURE IN FOUR MODES OF AEROBIC DANCE

Aerobic dance has been purported to help with weight management; however, it is not known if various forms of dance are as effective as traditional modalities. This study estimated energy expenditure by heart rate for 28 women participating in 4 modes of aerobic dance (Bodycombat [i.e., TAEBO]; Pump; Step; and RPM [i.e., spinning]) compared to 2 running speeds. Pump had significantly (p < 0.01) lower energy expenditure (8.0 ± 1.6 kcal·min−1) compared to the other classes (RPM: 9.9 ± 1.9 kcal·min−1; Step: 9.6 ± 1.8 kcal·min−1; and Bodycombat: 9.7 ± 2.0 kcal·min−1) and running at 8.05 km·h−1 (9.16 ± 1.53 kcal·min−1). Also, Step (p < 0.01), Bodycombat (p < 0.01), and RPM (p < 0.01) had significantly higher caloric expenditures than running at 8.05 km·h−1 but significantly lower than running at 8.37 km·h−1 (10.30 ± 1.72 kcal·min−1). In conclusion, RPM, Bodycombat, and Step aerobics were equally as effective as jogging between 8.05 and 8.37 km·h−1, and they met American College of Sports Medicine guidelines for weight modification and maintenance. Additionally, heart rate assessment provided a quantitative method for estimating energy expenditure and the effectiveness of different aerobic programs.
Chinese lingering, meditation's practice: reframing endurance art beyond resistance

This article explores the methodological possibilities of using meditation, breath, and affects to situate contemporary Chinese art, particularly Zhang Huan's 12 Square Meters and He Chengyao's 99 Needles. Through the haptic dimensions embedded within meditation, I complicate the oft-deployed frameworks of endurance art and conscious resistance applied to Chinese artists that “challenge” the state. I propose lingering as an alternative possibility for durational, time-based practices. Drawing from Henri Bergson's accounts of duration, lingering emphasizes indeterminate and slippery experiences within time that shift away from masculinist notions of linearity and intention. The indeterminacy and failures of lingering destabilize how Chinese artists are often understood as conscious, agentic actors who perform resistance through endurance. Lingering, self-practice, and meditation renegotiate and temper our normative and ableist understandings of agency, resistance, and consciousness. As such, this article contributes to disability and new materialist engagements with normative modes of consciousness, contending with the need for considering the social alongside reformulations of the subject.
Father Absence, Social Structure, and Attention Allocation in Children: A Four‐Culture Comparison

Beatrice Whiting, together with John Whiting, pioneered comparative field research in anthropology. The present study builds on one of her Six Culture Project contributions, an analysis of the effects of early father absence as mediated by social- structural characteristics. In a four-culture comparison, we find that (a) high frequency of father absence and male dominance in the adult world (as among the Logoli of Kenya) seem to prompt those boys with fathers to allocate to their fathers a high level of attention; and (b) high frequency of father absence and nondominance of males in the adult world (as among the Black Carib of Belize) seem to prompt those boys with fathers to allocate to their fathers an extremely low level of attention. In all four cultures, however, those boys without fathers allocated to males a high level of attention. The attention levels of girls were unaffected by father absence. The findings extend and refine the original contribution of Beatice Whiting while introducing new complexities into the study of father absence and its effects.

Activity profile and physical demands of male field hockey umpires in international matches

Abstract In this study, we investigated the physical demands and activity profiles of international field hockey umpires during match-play. We collected GPS data and heart rates from ten umpires over 16 international matches. Total mean distance covered in a full match was 6655±406 m. No differences were observed between mean distances covered in the first and second halves (3390±241 m and 3264±253 m respectively; P =0.093). Hockey umpires spent 2.7±1% of the total match time performing high-intensity running (>15.5 km · h–1). Paired t-tests revealed no difference in the distance umpires covered during high-intensity running in the first versus the second half (339±168 m vs. 285±106 m; P=0.113), or in the number of sprints performed (3.4±2.3 vs. 2.8±2.1; P=0.290). There was large inter-individual variability in the total distance covered at high intensity (range 274–999 m). No difference in mean heart rates was evident between the first and second half (150±9 and 147±10 beats · min–1 respectively; P =0.055). The results of this study show that the performance of the participating hockey umpires did not decrease from the first to the second half. Training and testing procedures should be updated to reflect the specific role of the hockey umpire.

Proximity and Power Factors in Western Coverage of the Sub-Saharan AIDS Crisis

This content analysis explores the relationship between proximity/power status factors and news coverage of AIDS in sub-Saharan Africa in the elite press of the United States and Britain. Coverage from six publications—Time, Newsweek, U.S. News & World Report, The Economist, New York Times, and London Times—was compared with reported AIDS incidence in the hardest-hit African countries over two decades. AIDS coverage was related to year of publication, country of origin, and former colony status. Strongest predictors of coverage included military spending, scientific research, GDP, GNP, population, government type, and number of highways. Proximity and power status factors may mediate the flow of capital (information, money, and goods) between dominant and dependent nations.
Sub- and super-fidelity as bounds for quantum fidelity

We derive several bounds on fidelity between quantum states. In particular we show thatfidelity is bounded from above by a simple to compute quantity we call super-fidelity.It is analogous to another quantity called sub-fidelity. For any two states of a two-dimensional quantum system (N = 2) all three quantities coincide. We demonstratethat sub- and super-fidelity are concave functions. We also show that super-fidelity issuper-multiplicative while sub-fidelity is sub-multiplicative and design feasible schemesto measure these quantities in an experiment. Super-fidelity can be used to define adistance between quantum states. With respect to this metric the set of quantum statesforms a part of a N2 - 1 dimensional hypersphere.
Kobe University Repository : Kernel タイトル Tit le A Lagrangian relaxat ion-based heurist ic for the vehicle rout ing with full container load 著者

We address a problem of vehicle routing that arises in picking up and delivering full container load from/to an intermodal terminal. The substantial cost and time savings are expected by efficient linkage between pickup and delivery tasks, if the time of tasks and the suitability of containers for cargo allow. As this problem is NP-hard, we develop a subgradient heuristic based on a Lagrangian relaxation which enables us to identify a near optimal solution. The heuristic consists of two sub-problems: the classical assignment problem and the generalized assignment problem. As generalized assignment problem is also NP-hard, we employ an efficient solution procedure for a bin packing based problem, which replaces the generalized assignment problem. The heuristic procedure is tested on a wide variety of problem examples. The test results demonstrate that the procedure developed here can efficiently solve large instances of the problem.

Osteogenic protein‐1 (OP‐1, BMP‐7) induces osteoblastic cell differentiation of the pluripotent mesenchymal cell line C2C12

The effects of Osteogenic Protein‐1 (OP‐1, BMP‐7) on the differentiation of the pluripotent mesenchymal cell line, C2C12, were examined. OP‐1 at 50 ng/ml partially inhibited myotube formation in C2C12 cells, while OP‐1 at 200 ng/ml completely inhibited myotube formation and induced the formation of cells displaying osteoblastic morphology. High concentrations of OP‐1 elevated the alkaline phosphatase (AP) activity dramatically, both as a function of time and OP‐1 concentration. Osteocalcin (OC) mRNA expression was detected as early as 8 days in OP‐1‐treated cultures and subsequently increased considerably. Expression of bone sialoprotein (BSP) mRNA was low in control cultures and stimulated by OP‐1. Collagen type I mRNA expression was enhanced by OP‐1 during the early days in culture, but gradually decreased thereafter. MyoD mRNA expression, high in control cultures, was suppressed by OP‐1 in a dose‐ and time‐dependent manner. OP‐1 enhanced ActR‐I mRNA expression and significantly elevated the mRNA expressions of BMP‐1, BMP‐4, BMP‐5, GDF‐6, and GDF‐8. The present results indicate that OP‐1 is a potent inducer of C2C12 differentiation into osteoblastic cells. J. Cell. Biochem. 87: 292–304, 2002. © 2002 Wiley‐Liss, Inc.
