Hypergeometric generating functions for values of Dirichlet and other L functions

Although there is vast literature on the values of L functions at nonpositive integers, the recent appearance of some of these values as the coefficients of specializations of knot invariants comes as a surprise. Using work of G. E. Andrews [(1981) Adv. Math. 41, 173–185; (1986) q-Series: Their Development and Application in Analysis, Combinatories, Physics, and Computer Algebra, Conference Board of the Mathematical Sciences Regional Conference Series in Mathematics 66 (Am. Math. Soc, Providence, RI); (1975) Problems and Prospects for Basic Hypergeometric Series: The Theory and Application of Special Functions (Academic, New York); and (1992) Illinois J. Math. 36, 251–274], we revisit this old subject and provide uniform and general results giving such generating functions as specializations of basic hypergeometric functions. For example, we obtain such generating functions for all nontrivial Dirichlet L functions.
Pregabalin use early in pregnancy and the risk of major congenital malformations

Objective: To assess whether first-trimester exposure to pregabalin is associated with an increased risk of major congenital malformations, as recently suggested in a pregnancy registry study. Methods: We performed a cohort study nested in the US Medicaid Analytic eXtract (MAX). The study population included 1,323,432 pregnancies resulting in a live-born infant between 2000 and 2010. We examined the risk of major congenital malformations among infants born to women exposed to pregabalin during the first trimester compared with women unexposed to anticonvulsants. We used propensity score fine stratification to control for >50 potential confounders, and we estimated relative risks (RRs) and 95% confidence intervals (CIs) in generalized linear models. The analyses were replicated in the Truven Health MarketScan Commercial Database (MarketScan). Pooled estimates based on the adjusted RR produced in MAX, MarketScan, and the previous registry study were calculated. Results: Of 477 infants exposed to pregabalin during the first trimester in MAX, 28 (5.9%) had malformations compared to 3.3% in nonexposed infants. The crude RR of major congenital malformations for pregabalin was 1.80 (95% CI 1.26–2.58). After propensity score adjustment, the RR moved to 1.16 (95% CI 0.81–1.67). Restriction to pregabalin monotherapy and sensitivity analyses produced similar results. The adjusted RR for major congenital malformations for the 174 infants exposed in MarketScan was 1.03 (95% CI 0.56–1.90). The pooled RR was 1.33 (95% CI 0.83–2.15) for pregabalin any use and 1.02 (95% CI 0.69–1.51) for pregabalin monotherapy. Conclusions: Findings did not confirm the suggested teratogenic effects of pregabalin, although they cannot rule out the possibility of a small effect.
High-Sensitivity CMOS Super-Regenerative Receiver with Quench-Controlled High-$Q$  Metamaterial Resonator for Millimeter-Wave Imaging at 96 and 135 GHz

High-sensitivity super-regenerative receivers (SRXs) are demonstrated at 96 and 135 GHz, respectively, in this paper. They are based on high-Q quench-controlled metamaterial resonators with a differential transmission line loaded with a split-ring resonator (DTL-SRR) and a differential transmission line loaded with a complementary split-ring resonator (DTL-CSRR) in 65-nm CMOS. High-Q oscillatory amplifications are established by the sharp stopband introduced by metamaterial resonators. As such, high detection sensitivity is achieved for SRXs at millimeter-wave regions. The fabricated 96-GHz DTL-CSRR-based SRX has a compact core chip area of 0.014 mm2 with measured power consumption of 2.8 mW, sensitivity of -79 dBm, noise figure (NF) of 8.5 dB, and noise equivalent power (NEP) of 0.67 fW/√(Hz). The fabricated 135-GHz DTL-SRR-based SRX has a compact core chip area of 0.0085 mm2 with measured power consumption of 6.2 mW, sensitivity of -76.8 dBm, NF of 9.7 dB, and NEP of 0.9 fW/√(Hz). Compared to the conventional SRX with an LC-tank-based resonator at similar frequencies, the proposed SRXs have 2.8~4 dB sensitivity improvement and 60% smaller area. The integrated SRXs are also demonstrated for the imaging applications.
Low Complexity Data Decoding for SLM-Based OFDM Systems without Side Information

Selected mapping (SLM) scheme is a well-known technique for peak-to-average power ratio (PAPR) reduction in orthogonal frequency division multiplexing (OFDM) systems. To recover data at receiver, the SLM scheme requires transmission of the selected phase sequence index, e.g., side information (SI). In this letter, a new pilot phase sequence enabling data recovery without SI and a low complexity decoding scheme are proposed. The BER performance of the proposed scheme is approximately the same in comparison with the SLM scheme with SI and considerably better than that of the Maximum Likelihood (ML) decoding scheme. In addition, the computational complexity of the proposed decoding scheme is much lower, as compared to the ML decoding scheme.
Environmental Factors Determining the Epidemiology and Population Genetic Structure of the Bacillus cereus Group in the Field

Bacillus thuringiensis (Bt) and its insecticidal toxins are widely exploited in microbial biopesticides and genetically modified crops. Its population biology is, however, poorly understood. Important issues for the safe, sustainable exploitation of Bt include understanding how selection maintains expression of insecticidal toxins in nature, whether entomopathogenic Bt is ecologically distinct from related human pathogens in the Bacillus cereus group, and how the use of microbial pesticides alters natural bacterial populations. We addressed these questions with a MLST scheme applied to a field experiment in which we excluded/added insect hosts and microbial pesticides in a factorial design. The presence of insects increased the density of Bt/B. cereus in the soil and the proportion of strains expressing insecticidal toxins. We found a near-epidemic population structure dominated by a single entomopathogenic genotype (ST8) in sprayed and unsprayed enclosures. Biopesticidal ST8 proliferated in hosts after spraying but was also found naturally associated with leaves more than any other genotype. In an independent experiment several ST8 isolates proved better than a range of non-pathogenic STs at endophytic and epiphytic colonization of seedlings from soil. This is the first experimental demonstration of Bt behaving as a specialized insect pathogen in the field. These data provide a basis for understanding both Bt ecology and the influence of anthropogenic factors on Bt populations. This natural population of Bt showed habitat associations and a population structure that differed markedly from previous MLST studies of less ecologically coherent B. cereus sample collections. The host-specific adaptations of ST8, its close association with its toxin plasmid and its high prevalence within its clade are analogous to the biology of Bacillus anthracis. This prevalence also suggests that selection for resistance to the insecticidal toxins of ST8 will have been stronger than for other toxin classes.
The moral base for teacher professionalism

Hugh Sockett aims to fill a gap in the body of literature concerning moral foundations in education. Dr Sockett posits that moral language must be used as the primary language of educators and that a major transformation across all educational institutions is needed to sustain the collegial autonomy crucial to educational improvement. His thesis is that moral quality in teacher professionalism is based in four principle areas: community, knowledge, accountability and ideals. Through an accessible writing style and an apt use of case studies, he links the professional role of the teacher, the men and women who occupy it, the moral demands it makes, and the practical arts of teaching, to the institution of education and its contemporary problems. Sockett's focus is on the teacher as a living and central figure in the classroom, and he addresses the traits of idealism and altruism as agents of professionalism. This book should be of particular interest to pre- and in-service teacher educators, as well as to curriculum specialists and philosphers of education. It can also serve as a supplemental text in ethics courses.
Comparing local search paths with global search paths on protein residue networks: allosteric communication

Although proteins have been recognized as small-world networks and their small-world network properties of clustering and short paths have been exploited computationally to produce biologically relevant information, they have not been truly explored as such, i.e. as navigable small-world networks in the original spirit of Milgram's work. This research seeks to fill this gap by exploring local search on a network representation of proteins and to probe the source of navigability in proteins. Previously, we confirmed that proteins are navigable small-world networks and observed that local search paths exhibit different characteristics from global search paths. In this paper, we investigate the biological relevance of the differences in path characteristics on a type III receptor tyrosine kinase (KIT). A chief difference that works in favour of local search paths as intra-protein communication pathways is their weaker proclivity, compared to global search paths, for traversing long-range edges. Long-range edges tend to be less stable and their inclusion tends to decrease the communication propensity of a path. The source of protein navigability is traced to clustering provided by short-range edges. The majority of a protein's short-range edges reside within structures deemed important for long-range energy transport and modulation of allosteric communication in proteins. Therefore, the disruption of intra-protein communication as a result of the destruction of these structures via random rewiring is expected. A local search perspective leads us to this expected conclusion while a global search perspective does not. These findings initiate the compilation of a list of path properties that are characteristic of intra-protein pathways and could suggest fresh avenues for evolving and regulating navigable (small-world) networks.
Hebb repetition effects for non-verbal visual sequences: determinants of sequence acquisition

ABSTRACT We report four experiments premised upon the work of Horton et al. [(2008). Hebb repetition effects in visual memory: The roles of verbal rehearsal and distinctiveness. Quarterly Journal of Experimental Psychology, 61(12), 1769–1777] and Page et al. [(2013). Repetition-spacing and item-overlap effects in the Hebb repetition task. Journal of Memory and Language, 69(4), 506–526], and explore conditions under which the visual Hebb repetition effect is observed. Experiment 1 showed that repetition learning is evident when the items comprising the non-repeated (filler) sequences and the repeated (Hebb) sequences are different (no-overlap). However, learning is abolished when the filler and Hebb sequences comprise the same items (full-overlap). Learning of the repeated sequence persisted when repetition spacing was increased to six trials (Experiment 2), consistent with that shown for verbal stimuli (Page et al., 2013). In Experiment 3, it was shown that learning for the repeated sequence is accentuated when the output motor response at test is also repeated for the Hebb sequence, but only under conditions of no-overlap. In Experiment 4, repetition spacing was re-examined with a repeated motor output response (a closer methodological analogue to Page et al., 2013). Under these conditions, the gradient of Hebb repetition learning for six trial repetition intervals was markedly similar to that for three trial intervals. These findings further support the universality of the Hebb repetition effect across memory and are discussed in terms of evidence for amodality within-sequence memory.
Joint Attention in Young Children with Autism

Autism spectrum disorders (ASDs) are classified as pervasive developmental disorders characterized by social, communicative, and behavioral impairments. According to formal and informal reports, children with ASD present with receptive and expressive language delay. Joint attention (JA: the behavior that occurs when two individuals focus on the same object or event) has been identified as a possible marker of delayed language development in children with ASD. In this study, the JA behaviors in children with ASD were contrasted with initially languagematched typically developing (TYP) children across three visits. Measures of language, the frequency, duration, and source of initiation of JA episodes, and the choice of toy during those episodes, were coded. Across visits and groups, mothers initiated more JA episodes than children; however, typical children also initiated more JA episodes than ASD children at visits 1 and 2. Also, the total duration of typically developing children’s JA episodes was generally longer than that of the ASD children’s, significantly so at Visit 2. Significant associations emerged between children’s vocabulary and two measures of JA: frequency and number of maternal initiations. Teaching parents to incorporate JA training in their interactions with their children may likely help children with ASD acquire language.
Mediators and Moderators in the Relative Deprivation – Crime/Counter-normative Actions Relationship

Researchers have failed to specify when crime and counter-normative actions, as opposed to other responses may occur as a consequence of relative deprivation. To clarify this issue, a mediational model was developed that specified the causal processes leading from the recognition of deprivation to crime and counter-normative actions. This model hypothesizes that the recognition of deprivation (cognitive relative deprivation) leads to feelings associated with this recognition (affective relative deprivation) which in turn leads to crime and counter-normative actions. This model applies to both personal and group deprivation. In both cases, the feelings associated with deprivation include anger, resentment, dissatisfaction, and discontent. Data from a sample of 950 males between the ages of 16 to 30 supported the mediational model. Moderator variables were hypothesized to influence the causal processes in the mediational model, and were thus employed to specify the conditions under which the recognition of deprivation became more likely to lead to intense emotional reactions, and the conditions under which these emotional reactions became more likely to lead to crime and counter-normative actions. Personal deprivation was found to lead to stronger emotional responses if persons were pessimistic about their deprivation being relieved in the future, while at the group level, higher levels of optimism were related to stronger emotional responses. Both types of deprivation also lead to stronger emotional responses when persons believe that financial success and wealth are important. The emotive responses for both personal and group deprivation, in turn, were more likely to lead to crime and counter-normative actions if deprived persons had criminal peers. It was also found that the recognition of personal deprivation was more likely to lead to depression and lower self-esteem if people blamed themselves for their deprivation than if they did not. Persons who were not optimistic that their deprivation would be relieved in the future were more depressed than persons who were optimistic. Persons whose in-group was deprived were more likely to have lower self-esteem if they blamed the in-group for its deprivation than if they did not.
Spinal Versus Epidural Anesthesia for Cesarean Section: A Comparison of Time Efficiency, Costs, Charges, and Complications

Spinal anesthesia recently has gained popularity for elective cesarean section.Our anesthesia service changed from epidural to spinal anesthesia for elective cesarean section in 1991. To evaluate the significance of this change in terms of time management, costs, charges, and complication rates, we retrospectively reviewed the charts of patients who had received epidural (n = 47) or spinal (n = 47) anesthesia for nonemergent cesarean section. Patients who received epidural anesthesia had significantly longer total operating room (OR) times than those who received spinal anesthesia (101 +/- 20 vs 83 +/- 16 min, [mean +/- SD] P < 0.001); this was caused by longer times spent in the OR until surgical incision (46 +/- 11 vs 29 +/- 6 min, P < 0.001). Length of time spent in the postanesthesia recovery unit was similar in both groups. Supplemental intraoperative intravenous (IV) analgesics and anxiolytics were required more often in the epidural group (38%) than in the spinal group (17%) (P < 0.05). Complications were noted in six patients with epidural anesthesia and none with spinal anesthesia (P < 0.05). Average per-patient charges were more for the epidural group than for the spinal group. Although direct cost differences between the groups were negligible, there were more substantial indirect costs differences. We conclude that spinal block may provide better and more cost effective anesthesia for uncomplicated, elective cesarean sections. (Anesth Analg 1995;80:709-12)
Land cover and tsetse fly distributions in sub‐Saharan Africa

Abstract This study aims to provide trypanosomiasis‐affected countries with standardized datasets and methodologies for mapping the habitat of the tsetse fly (Glossina spp., the disease vector) by customizing and integrating state‐of‐the‐art land cover maps on different spatial scales. Using a combination of inductive and deductive approaches, land cover and fly distribution maps are analysed in a geographic information system (GIS) to estimate the suitability of different land cover units for the three groups (subgenera) of Glossina. All land cover datasets used for and produced by the study comply with the Land Cover Classification System (LCCS). At the continental scale, a strong correlation between land cover and tsetse habitat is found for both the fusca and palpalis groups, whereas a weaker correlation found for the morsitans group may be indicative of less restrictive ecological requirements. At the regional and national levels, thematic aggregation of the multi‐purpose Africover datasets yielded high‐resolution, standardized land cover maps tailored for tsetse habitat for eight East African countries. The national maps provide remarkable spatial resolution, thematic detail and geographical coverage. They may be applied in subsequent phases of tsetse and trypanosomiasis control projects, including the planning of entomological surveys, actual tsetse control operations and planning for land use in reclaimed areas. The methodology and datasets discussed in the paper may have applications beyond the tsetse and trypanosomiasis issue and may be used with reference to other arthropod vectors, vector‐borne and parasitic diseases.
Characterizing Degrees of Freedom Through Additive Combinatorics

We establish a formal connection between the problem of characterizing degrees of freedom (DoF) in constant single-antenna interference channels (ICs) with general channel matrix and the field of additive combinatorics. The theory we develop is based on a recent breakthrough result by Hochman, 2014, in fractal geometry. Our first main contribution is an explicit condition on the channel matrix to admit full, i.e., K/2 DoF; this condition is satisfied for almost all channel matrices. We also provide a construction of corresponding full DoF-achieving input distributions. The second main result is a new DoF-formula exclusively in terms of Shannon entropy. This formula is more amenable to both analytical statements and numerical evaluations than the DoF-formula by Wu et al., 2015, which is in terms of Rényi information dimension. We then use the new DoF-formula to shed light on the hardness of finding the exact number of DoF in ICs with rational channel coefficients, and to improve the best known bounds on the DoF of a well-studied channel matrix.
Anonymizing moving objects: how to hide a MOB in a crowd?

Moving object databases (MOD) have gained much interest in recent years due to the advances in mobile communications and positioning technologies. Study of MOD can reveal useful information (e.g., traffic patterns and congestion trends) that can be used in applications for the common benefit. In order to mine and/or analyze the data, MOD must be published, which can pose a threat to the location privacy of a user. Indeed, based on prior knowledge of a user's location at several time points, an attacker can potentially associate that user to a specific moving object (MOB) in the published database and learn her position information at other time points. In this paper, we study the problem of privacy-preserving publishing of moving object database. Unlike in microdata, we argue that in MOD, there does not exist a fixed set of quasi-identifier (QID) attributes for all the MOBs. Consequently the anonymization groups of MOBs (i.e., the sets of other MOBs within which to hide) may not be disjoint. Thus, there may exist MOBs that can be identified explicitly by combining different anonymization groups. We illustrate the pitfalls of simple adaptations of classical k-anonymity and develop a notion which we prove is robust against privacy attacks. We propose two approaches, namely extreme-union and symmetric anonymization, to build anonymization groups that provably satisfy our proposed k-anonymity requirement, as well as yield low information loss. We ran an extensive set of experiments on large real-world and synthetic datasets of vehicular traffic. Our results demonstrate the effectiveness of our approach.
Social support and quality of life among older people in Spain

Social support is a key concept in social gerontology; there is empirical evidence of its relationships with health, well–being and quality of life in old age. The density of an individual’s social relationships, the degree to which he/she interacts with others and how much he/she receives and gives affect, instrumental support, and/or services are all associated with health indicators, subjective well–being, and quality of life measures. This article deals with social support in old age in Spain, its relationships with health indicators, and its role in quality of life. Several descriptive studies dealing with social integration, frequency of social interactions, satisfaction with social relationships, and formal and informal social support are reviewed. Finally, the role attributed by elders to social relationships is an important conditioning factor of quality of life.
