Decoupled, rank reduced, massive and frequency-selective aspects in MIMO Interfering Broadcast Channels

The Interfering Broadcast Channel (IBC) applies to the downlink of cellular and heterogenous networks, which are limited by multi-user interference. The interference alignment (IA) concept has shown that interference does not need to be inevitable. In particular spatial IA in MIMO IBC allows for low latency and requires little diversity. However, IA requires perfect and typically global Channel State Information at the Transmitter(s) (CSIT), whose acquisition does not scale with network size. Hence, designs that are optimal in terms of Degrees of Freedom (DoF) may not be so in terms of more relevant net DoF, accounting for CSI acquistion. Also, the design of transmitters (Txs) and receivers (Rxs) is coupled and hence needs to be centralized or duplicated. Recently, a number of (usually suboptimal in terms of DoF) approaches with reduced, incomplete or local CSIT requirements have been introduced requiring less CSI acquisition overhead and allowing decoupled Tx/Rx designs. This network decomposition is aided by the for finite SNR more relevant topological IBC scenario, in which also reduced rank MIMO channels may appear. The transition to Massive MIMO furthermore introduces a reduced rank in the covariance CSIT and allows network decomposition. We will also highlight that any scenario allowing decomposition is favorable for the design of asynchronous frequency-selective networks.
Public-private partnerships for innovation-led growth in agrichains: A useful tool for development in Latin America?

Public-private partnerships have become increasingly important as an arrangement that serves to encourage innovation in agricultural production chains in Latin America. However, some observers have expressed concern that this institutional arrangement may mostly favor the interests of the private sector without producing sufficient social benefits for the public. This paper presents the results of a study of 124 cases of public-private partnerships in agricultural innovation in nine countries in Latin America. The data from the study suggest that the partnership concept is used to generate agricultural innovations in many different ways, involving public research and private entities to varying degrees and focusing on different types of agricultural products, processing, or marketing. The results indicate that public as well as private sector actors often enter into partnerships based on unclear expectations of the benefits to be obtained, but once involved, these actors are usually satisfied with the results. Given the high degree of satisfaction that partners experience in public-private partnerships, they constitute an interesting new tool for development. However, in many cases public sector agents do not clearly establish public priorities; in consequence, public sector goals are not addressed sufficiently. Also due to the limited commitment of some of the partners to partnerships their potentials of generating synergy are not met. One key recommendation to emerge from the study is that when entering into public-private partnerships, public agents should ensure that these partnerships comply with public needs.
The chloride effect of carbonic anhydrase inhibitors.

Sulfonamide carbonic anhydrase inhibitors not only inhibit carbonic anhydrase(s) but also the active transport of chloride by the gastric mucosa. The concentrations required for the latter effect are 100 or more times that required to block functions ascribed to the enzyme carbonic anhydrase. The slow rate of H+ ion secretion by the isolated mucosa is not inhibited by sulfonamide inhibitors. Agents that are the most potent inhibitors of carbonic anhydrase exert the greatest effect on chloride transport. Inactive analogs had no discernible effect on either system. For 15 agents, there is a striking parallel between their inhibition of chloride transport and the inhibition of carbonic anhydrase.
A Generative Model of Phonotactics

We present a probabilistic model of phonotactics, the set of well-formed phoneme sequences in a language. Unlike most computational models of phonotactics (Hayes and Wilson, 2008; Goldsmith and Riggle, 2012), we take a fully generative approach, modeling a process where forms are built up out of subparts by phonologically-informed structure building operations. We learn an inventory of subparts by applying stochastic memoization (Johnson et al., 2007; Goodman et al., 2008) to a generative process for phonemes structured as an and-or graph, based on concepts of feature hierarchy from generative phonology (Clements, 1985; Dresher, 2009). Subparts are combined in a way that allows tier-based feature interactions. We evaluate our models’ ability to capture phonotactic distributions in the lexicons of 14 languages drawn from the WOLEX corpus (Graff, 2012). Our full model robustly assigns higher probabilities to held-out forms than a sophisticated N-gram model for all languages. We also present novel analyses that probe model behavior in more detail.
Intervention among Suicidal Men: Future Directions for Telephone Crisis Support Research

Telephone crisis support is a confidential, accessible, and immediate service that is uniquely set up to reduce male suicide deaths through crisis intervention. However, research focusing on telephone crisis support with suicidal men is currently limited. To highlight the need to address service delivery for men experiencing suicidal crisis, this perspective article identifies key challenges facing current telephone crisis support research and proposes that understanding of the role of telephone crisis helplines in supporting suicidal men may be strengthened by careful examination of the context of telephone crisis support, together with the impact this has on help-provision for male suicidal callers. In particular, the impact of the time- and information-poor context of telephone crisis support on crisis-line staff’s identification of, and response to, male callers with thoughts of suicide is examined. Future directions for research in the provision of telephone crisis support for suicidal men are discussed.
Coexistence of episomal and integrated HPV16 DNA in squamous cell carcinoma of the cervix.

AIMS--To investigate the integration of human papillomavirus (HPV)16 in 13 HPV16 positive cervical squamous carcinomas. METHODS--Samples were investigated by Southern blot analysis of the Pst I digestion pattern, two-dimensional gel-electrophoresis, and in situ hybridisation. RESULTS--Integration of HPV16 was found in all cases. In 12 biopsy specimens episomal HPV16 DNA and integrated HPV16 DNA were seen. The episomal DNA occurred as dimers and multimers. In situ hybridisation showed that both integrated and episomal HPV16 DNA were present in the same cell in most tumour cell nuclei. CONCLUSIONS--An intact episomal E2 gene is present in most cases of these cervical cancers, and could therefore replace the regulatory function of an integrated defective E2 gene.
Growth Directions of Precipitates in the Al–Si–Mg–Hf Alloy Using Combined EBSD and FIB 3D-Reconstruction Techniques

Abstract Nanobelt-like precipitates in an Al–Si–Mg–Hf alloy were studied using electron backscattered diffraction (EBSD) and focused ion beam (FIB) scanning electron microscopy techniques. One grain of the Al matrix with a near [111] normal direction was identified by EBSD and the three-dimensional (3D) microstructure of nanobelt-like precipitates in this grain was studied using 3D-FIB. Ten growth directions of the nanobelt-like precipitates in the grain were identified.
From the “Faith to the Ideals and the Values of the Nation” to the “Ideological Extremeness” The Phenomenon of the Nationalism according to Greek University Students’ Opinions

The aim of this research is to inventory the means used by a population group with specific social characteristics, which have to do, on the one hand, with the school and social trajectory of the subjects but which on the other might have evolved – given their attendance - into a freer educational institution and assess the nationalism phenomenon. The sample of our research was constituted by 200 students, males and females, of the Pedagogical School of the University of Western Macedonia, who were invited to answer spontaneously the questionnaire of this research during the academic year 2006-07.For the data analysis, the Factor Analysis Method was chosen which is widely used in the filed of the Social Sciences. The Factor Analysis was used so as to become aware of the pattern of the response of the social subjects – students, as it gives us the possibility to draw precious conclusions about a sum of variables while diminishing their number to a smaller number of factors from which each of whom corresponds to several of the initials. From the students’ answers in their total, five analysis axes are revealed, on the semantics of the nationalism, the historical semantics, the cultural provenience of the nationalism, the political functions and the social inequalities.

P-MaNGA: GRADIENTS IN RECENT STAR FORMATION HISTORIES AS DIAGNOSTICS FOR GALAXY GROWTH AND DEATH

We present an analysis of the data produced by the MaNGA prototype run (P-MaNGA), aiming to test how the radial gradients in recent star formation histories, as indicated by the 4000 Å break (Dn(4000)), Hδ absorption (EW(HδA)), and Hα emission (EW(Hα)) indices, can be useful for understanding disk growth and star formation cessation in local galaxies. We classify 12 galaxies observed on two P-MaNGA plates as either centrally quiescent (CQ) or centrally star-forming (CSF), according to whether Dn(4000) measured in the central spaxel of each datacube exceeds 1.6. For each spaxel we generate both 2D maps and radial profiles of Dn(4000), EW(HδA), and EW(Hα). We find that CSF galaxies generally show very weak or no radial variation in these diagnostics. In contrast, CQ galaxies present significant radial gradients, in the sense that Dn(4000) decreases, while both EW(HδA) and EW(Hα) increase from the galactic center outward. The outer regions of the galaxies show greater scatter on diagrams relating the three parameters than their central parts. In particular, the clear separation between centrally measured quiescent and star-forming galaxies in these diagnostic planes is largely filled in by the outer parts of galaxies whose global colors place them in the green valley, supporting the idea that the green valley represents a transition between blue-cloud and red-sequence phases, at least in our small sample. These results are consistent with a picture in which the cessation of star formation propagates from the center of a galaxy outward as it moves to the red sequence.
Factors associated with knowledge of genetics and nutritional genomics among dietitians.

INTRODUCTION Knowledge of genetics and nutritional genomics is important for dietitians in the prevention and management of disease. The present study aimed to analyse data from a nationwide postal questionnaire survey in order to investigate the factors associated with knowledge of genetics and nutritional genomics among dietitians in the UK. METHODS A nationwide postal questionnaire survey was conducted in a random sample of 600 dietitians in the UK. The questionnaire measured dietitians' knowledge using 12 multiple choice questions relating to genetics and nutritional genomics. Factors that may impact upon such knowledge were also recorded. Knowledge scores were calculated and compared between dietitians using comparative statistics and univariate analysis of variance. RESULTS A total of 389 (64.8%) usable questionnaires were returned. Overall, the mean +/- SD total knowledge score was low at 41 +/- 19%. Highest qualification (F(2,372) = 9.1, P < 0.001), the genetics content of university education (F(2,372) = 7.1, P = 0.001) and reading literature or attending a conference relating to genetics or nutritional genomics within the last year (F(1,372) = 11.9, P = 0.001) were all associated with higher total knowledge scores. CONCLUSION Knowledge of genetics and nutritional genomics among dietitians is currently low, and better knowledge is associated with exposure to these in university education and continuing professional development.
Intraoperative Endoleak During EVAR: Frequency, Nature, and Significance

Objective: Endoleaks are critical complications of endovascular abdominal aortic aneurysm repair (EVAR). This study sought to determine the frequency and nature of intraoperative endoleaks and their impact on postoperative endoleak-related events. Methods: A retrospective chart review was performed of all patients who underwent EVAR at our institution. The impact of intraoperative endoleaks on postoperative endoleak rates and endoleak-related reintervention rates were assessed. Results: From December 18, 1996, to May 21, 2003, 241 patients underwent EVAR. An endoleak was observed during 126 (52.3%) procedures. Type I endoleaks were observed in 63 (26.1%) cases: 35 proximal and 31 distal endoleaks (3 cases at both attachments). Angioplasty, additional cuff placement, or stenting corrected 59 (89.4%) of these endoleaks. A total of 71 type II intraoperative endoleaks (29.5%) and 8 type IV endoleaks (3.3%) were observed without any attempted corrective maneuvers. Ten type III endoleaks (4.2%) occurred but all resolved with angioplasty or additional cuff placement. In all, 86 (35.7%) endoleaks persisted on completion angiogram. Patients with a type I or type II intraoperative endoleak were more likely to have an endoleak at 1.5 years (31.4% vs. 21.6%, P = .018). Reinterventions were required more often after an intraoperative type I endoleak (10% vs. 4%, P = .003). Patients with intraoperative endoleaks demonstrated a trend toward less postoperative aneurysm diameter reduction at 2 years (43.8% vs. 74.5%, P = .104). Conclusion: The presence of a type I or a type II endoleak during EVAR significantly increases the likelihood of a postoperative endoleak and should prompt a high degree of suspicion during follow-up.
Learning full pairwise affinities for spectral segmentation

This paper studies the problem of learning a full range of pairwise affinities gained by integrating local grouping cues for spectral segmentation. The overall quality of the spectral segmentation depends mainly on the pairwise pixel affinities. By employing a semi-supervised learning technique, optimal affinities are learnt from the test image without iteration. We first construct a multi-layer graph with pixels and regions, generated by the mean shift algorithm, as nodes. By applying the semi-supervised learning strategy to this graph, we can estimate the intra- and inter-layer affinities between all pairs of nodes together. These pair-wise affinities are then used to simultaneously cluster all pixel and region nodes into visually coherent groups across all layers in a single multi-layer framework of Normalized Cuts. Our algorithm provides high-quality segmentations with object details by directly incorporating the full range connections in the spectral framework. Since the full affinity matrix is defined by the inverse of a sparse matrix, its eigen-decomposition is efficiently computed. The experimental results on Berkeley and MSRC image databases demonstrate the relevance and accuracy of our algorithm as compared to existing popular methods.
Meditations on the premenstrual self : the conceptualization of self in the origins and development of the PMS discourse

The phenomenon of PMS Premenstrual Syndrome has received a significant amount of attention in the last 30 years both in the public discourse and as a subject of research in the social scientific and medical communities. A founding representation and a central narrative theme of the PMS discourse is women's experience of an altered or different sense of self a 'PMS self'. The split personality of the legendary Victorian character, 'Jekyll and Hyde' has been frequently invoked by the 'experts' and by women themselves to describe this different and, with the Hyde persona intended to represent their PMS self, mostly negatively construed sense of self that they experience in the postovulatory/premenstrual phase of their monthly cycles. Incorporating a sociohistorical critique and the results of a narrative analysis which I undertook, the work of this project is to explore the origins and development of the phenomenon of PMS and the 'PMS selflreal self characterization of the PMS experience in relation to theories and ideas that have been put forward in order to critique and posit alternative explanations for the sociocultural and historical sources of the contemporary notions of self, subjectivity, identity and the body. Using the theoretical and exploratory constructs of the Modern and Postmodern PMS Self I examine the ways in which women's understanding of themselves is interpreted through and within the hegemonic discourses and practices of the PMS discourse, which rest on static and dualistic notions of the self. I suggest that some of these interpretations can be read as a challenge to such notions in their positioning both as coping strategies for resisting the split-self identification and as a way of deriving insight and strength from the shifts in feeling and emotion that take place over the course of natural, normal womanly cycles.
Creativity and Surprise

This paper describes a computational model for creativity in which surprise plays a central role. There is no doubt that creative products, being unexpected and unpredictable products, cause surprise. In order to make those products surprising and supported by recent evidences from neuroscience, which say emotions are biasing devices in decision-making, we defend that decisions made during the creative process may be, consciously or unconsciously, to some extent, surprise-guided. Moreover, when evaluating a product in what concerns to its creativity, the degree of surprise that product causes is certainly one part of that evaluation. We illustrate with examples the role played by surprise both in the production of creative products and in the evaluation of already existing creative products.
Comparison of T7E1 and Surveyor Mismatch Cleavage Assays to Detect Mutations Triggered by Engineered Nucleases

Genome editing using engineered nucleases is used for targeted mutagenesis. But because genome editing does not target all loci with similar efficiencies, the mutation hit-rate at a given locus needs to be evaluated. The analysis of mutants obtained using engineered nucleases requires specific methods for mutation detection, and the enzyme mismatch cleavage method is used commonly for this purpose. This method uses enzymes that cleave heteroduplex DNA at mismatches and extrahelical loops formed by single or multiple nucleotides. Bacteriophage resolvases and single-stranded nucleases are used commonly in the assay but have not been compared side-by-side on mutations obtained by engineered nucleases. We present the first comparison of the sensitivity of T7E1 and Surveyor EMC assays on deletions and point mutations obtained by zinc finger nuclease targeting in frog embryos. We report the mutation detection limits and efficiencies of T7E1 and Surveyor. In addition, we find that T7E1 outperforms the Surveyor nuclease in terms of sensitivity with deletion substrates, whereas Surveyor is better for detecting single nucleotide changes. We conclude that T7E1 is the preferred enzyme to scan mutations triggered by engineered nucleases.
Calmodulin-like protein CML37 is a positive regulator of ABA during drought stress in Arabidopsis

Plants need to adapt to various stress factors originating from the environment. Signal transduction pathways connecting the recognition of environmental cues and the initiation of appropriate downstream responses in plants often involve intracellular Ca2+ concentration changes. These changes must be deciphered into specific cellular signals. Calmodulin-like proteins, CMLs, act as Ca2+ sensors in plants and are known to be involved in various stress reactions. Here, we show that in Arabidopsis 2 different CMLs, AtCML37 and AtCML42 are antagonistically involved in drought stress response. Whereas a CML37 knock-out line, cml37, was highly susceptible to drought stress, CML42 knockout line, cml42, showed no obvious effect compared to wild type (WT) plants. Accordingly, the analysis of the phytohormone abscisic acid (ABA) revealed a significant reduction of ABA upon drought stress in cml37 plants, while in cml42 plants an increase of ABA was detected. Summarizing, our results show that both CML37 and CML42 are involved in drought stress response but show antagonistic effects.
What Drives Legislators’ Information Behavior? An Eye-Tracking Experiment with Legislators

Existing theoretical accounts on legislators’ information behavior are eclectic. In one way or another, these accounts suggest that legislators use or ignore information based on its potential to solve a policy problem or enhance career prospects. We argue that these reasons do not represent triggers strong enough for an individual legislator to engage herself in the cognitive work necessary. Instead, we suggest that legislators have no substantial interest in policy-relevant information until their political intuitions are in conflict and fail to provide orientation. Only then does information search and use behavior precede judgments. If political intuitions are in line, information search and use are employed post hoc and provide arguments for the position that has been reached intuitively. To test the hypotheses that follow from this model on legislators’ information interest, search, and use, we conduct an eye-tracking experiment with 56 legislators. Eye-tracking metrics highlight that if political intuitions are contradicted, legislators’ interest in available information is more intense, their search behavior is less distorted, and available information is used differently during the deliberation process. We conclude that an intuitionist model of information behavior provides more plausible explanations for legislators’ observed information behavior in the political arena.
Introduction to Effective Music Teaching: Artistry and Attitude

Introduction to Effective Music Teaching: Artistry and Attitude provides the prospective teacher with front-line tested strategies and approaches that are based on current research and the author's three decades of service as a public school music educator, department chairman, and public school district music administrator. Starting with a brief overview of the history of music education in public schools, Alfred Townsend gives the reader a deeper understanding of the importance of music education to all students, gifted or not. Readers then examine artistry (command of content and mastery of methods) and the ABCs of teacher attitude, the critical component that unlocks learning for many students. With an open and accessible writing style, Dr. Townsend reviews the six components of effective teaching, showing that artistry and attitude can be combined to fuel student learning and teacher leadership. Using all of this information, the reader constructs a personal, practical philosophy of music teaching and learning that will form the basis for his or her instruction. Readers will also experience artistry and attitude in action through well-written case studies of effective teachers. With increasingly diverse student populations teachers now face, this book provides music teachers with ways to interact effectively with students of all backgrounds, attitudes, and talent.
