Real-Time Distributed Implementation of Interference Alignment with Analog Feedback

Abstract : Interference alignment (IA) is known to achieve the maximum capacity for the interference channel. IA is a precoding technique to make interfering signals be aligned at receivers. The resulting sum rate is linearly scaled with the number of users. The performance of IA, however, depends on the practical issues such as the performance of synchronization, channel estimation and feedback. In this paper, a prototype is implemented for the IA system with three users. There have been IA prototypes in recent years, but the previous prototypes have not considered the distribution of the nodes in IA network. The nodes are physically distributed in our prototype not sharing their time and frequency references with any other, thus working independently, which enables the experimental study of IA under the most practical setup. For the distributed system, the over-the-air schemes for time and frequency synchronization and analog feedback are studied and implemented. According to the measurement from our prototype, it is shown that IA achieves the sum rate from the previous analysis on imperfect channel information. In addition, some other measurements are performed considering the accuracy of IA solution, synchronization of nodes, and CSI feedback. For the accuracy of IA solution, the performance of IA versus the number of iterations for an iterative IA method is measured. For synchronization accuracy, the performance with different residual frequency offset is measured. Finally, for the CSI feedback quality, analog feedback and scaler quantization-based limited feedback is first compared, and then the performance with Doppler frequency offset is also measured.
Early Interventions: preventing school exclusions in the primary setting

Abstract This article considers the work of one project which is working to support children who are ‘at risk’ of being excluded. Including Primary School Children (IPSC) has been working in high excluding primary schools in one inner‐London local education authority (LEA), promoting strategies for inclusion. Formally excluding children from their primary schools is a serious step. While some schools may feel they have no alternative but to exclude, a ‘solution’ for the school may add to the problems experienced by excluded children and their families. What is needed is early intervention, where schools can target ‘at risk’ children and, even more positively, prevent the damage of exclusion through promoting mental, emotional and social health for all children.
An Improvement of Shotgun Proteomics Analysis by Adding Next-Generation Sequencing Transcriptome Data in Orange

Background Shotgun proteomics data analysis usually relies on database search. Because commonly employed protein sequence databases of most species do not contain sufficient protein information, the application of shotgun proteomics to the research of protein sequence profile remains a big challenge, especially to the species whose genome has not been sequenced yet. Methodology/Principal Findings In this paper, we present a workflow with integrated database to partly address this problem. First, we downloaded the homologous species database. Next, we identified the transcriptome of the sample, created a protein sequence database based on the transcriptome data, and integtrated it with homologous species database. Lastly, we developed a workflow for identifying peptides simultaneously from shotgun proteomics data. Conclusions/Significance We used datasets from orange leaves samples to demonstrate our workflow. The results showed that the integrated database had great advantage on orange shotgun proteomics data analysis compared to the homologous species database, an 18.5% increase in number of proteins identification.
Heterogeneous activity of immature and mature cells of the murine monocyte-macrophage lineage derived from different anatomical districts against yeast-phase Candida albicans

Mature mononuclear phagocytes have been receiving much attention as effectors of spontaneous candidacidal activity, although with controversial results due to differences in the effector populations and the methods used in different laboratories. We here systematically compare the fungistatic activity of immature and mature cells of the murine macrophage series. The results show that nonadherent, nonphagocytic precursor cells (isolated either [90% purity] from bone marrow liquid cultures or from the organs of mice in which inflammatory conditions had been elicited in vivo) exerted a strong extracellular candidastatic activity. In contrast, mature macrophages, either obtained from different anatomical areas (spleen, liver, lung, peritoneal cavity) or matured in vitro from the precursor populations, displayed striking heterogeneity in their ability to inhibit the growth of Candida albicans, depending on the anatomical site they were derived from. Lymphokine activation did not alter the fungistatic pattern of the untreated cells. The different macrophage populations behaved very differently also in the production of reactive oxygen intermediates (ROI) in response to phagocytosis of C. albicans. The amounts of ROI generated, however, showed no correlation with candidastatic ability. Low levels of candidastatic activity exerted by resident peritoneal macrophages (good ROI producers) were inhibited by catalase, whereas high levels of growth inhibition by Kupffer cells (poor ROI producers) after 8 h of assay were hardly influenced by the enzyme. Our data suggest the existence of two different effector mechanisms in macrophage-mediated C. albicans growth inhibition, a rather inefficient ROI-dependent one, and a second, very efficient oxygen-independent mechanism. The implications of these findings are discussed.
Relationship between how nurses resolve their conflicts with doctors, their stress and job satisfaction.

BACKGROUND A significant source of stress in nursing is conflict with physicians. There is evidence in the published literature that different ways of resolving conflicts generate more or less stress for those involved. AIM This research examines what tactics nurses adopt to resolve conflicts with doctors and how the different tactics affect their level of stress and job satisfaction. METHOD Seventeen nurses of varying seniority answered four questionnaires. RESULTS The integrating and dominance approaches to conflict resolution are associated with low occupational stress levels, whereas the obliging and avoidance approaches are linked to higher stress. There is evidence that the seniority and status of nurses affect both their choice of conflict-resolution tactics and the associated stress and job satisfaction levels. CONCLUSION Both nurses and physicians should be made more aware of the conflicts between them and better trained to understand how they can be constructively resolved.
Sensitivity Analysis in Discrete Event Simulation Using Design of Experiments

However, one of simulation’s greatest disadvantages is that, on its own, it does not serve as an optimization technique [7]. This forces simulation practitioners to simulate multiple system configurations and choose the one which presents the best system performance. Computational development has helped alter this scenario due to the increasing availability of faster computers and ever improving search and heuristic optimization techniques.
Dwelling and Seeking in Late Adulthood: The Psychosocial Implications of Two Types of Religious Orientation

SUMMARY This article summarizes quantitative findings and presents two illustrative case studies showing how religious dwelling and spiritual seeking evolve over the adult life course and relate to psychosocial functioning in late adulthood. The data come from the Institute of Human Development (IHD) longitudinal study of men and women. Religious dwellers tend to emphasize traditional forms of religious behavior whereas spiritual seekers emphasize innovative religious practices. In the IHD study, the religious involvement of the dwellers tended to be highly stable over the life course whereas spirituality gained in salience in the second half of adulthood. In late adulthood, religious dwelling was associated with maintaining close and warm relations with others and communal involvement, and during times of adversity, religiousness served as a buffer against the loss of life satisfaction. Spiritual seeking was associated with an emphasis on personal growth, creativity, and acquiring new knowledge. Spiritual growth was particularly characteristic of introspective individuals who in early adulthood experienced stressful life events.
Monocyte Chemoattractant Protein-1 Induces a Novel Transcription Factor That Causes Cardiac Myocyte Apoptosis and Ventricular Dysfunction

Monocyte chemoattractant protein-1 (MCP-1; CCL2)–mediated inflammation plays a critical role in the development of ischemic heart disease (IHD). However, the gene expression changes caused by signal transduction, triggered by MCP-1 binding to its receptor CCR2, and their possible role in the development of IHD are not understood. We present evidence that MCP-1 binding to CCR2 induces a novel transcription factor (MCP-induced protein [MCPIP]) that causes cell death. Gene microarray analysis showed that when expressed in hiuman embryonic kidney 293 cells, MCPIP induced apoptotic gene families before causing cell death. Mutagenesis studies showed that the structural features required for transcription factor–like activity were also required for causing cell death. Activation of caspase-3 was detected after MCPIP transfection and Z-VAD-fmk partially inhibited cell death. Cardiomyocyte-targeted expression of MCP-1 in mice caused death by heart failure at 6 months of age. MCPIP expression increased in parallel with the development of ventricular dysfunction. In situ hybridization showed the presence of MCPIP transcripts in the cardiomyocytes and immunohistochemistry showed that MCPIP was associated with the cardiomyocyte nuclei of apoptotic cardiomyocytes. CCR2 expression in cardiomyocytes increased with the development of IHD. MCPIP production induced by MCP-1 binding to CCR2 in the cardiomyocytes is probably involved in the development of IHD in this murine model. MCPIP transcript levels were much higher in the explanted human hearts with IHD than with nonischemic heart disease. These results provide a molecular insight into how chronic inflammation and exposure to MCP-1 contributes to heart failure and suggest that MCPIP could be a potential target for therapeutic intervention.
How Strong are Strong Ties? The Conditional Effectiveness of Strong Ties in Protest Recruitment Attempts

Why do some individuals accept invitations to participate in protest events while others do not? Using the Citizen Participation Study, the author finds that targets invited by recruiters to whom they are strongly tied are more likely to protest than those invited by weak or absent ties. Such effect, however, is hypothesized to vary across the socioeconomic structure. Although strong ties motivate targets to accept the invitation, only those with sufficient resources could translate motivation into action. Consistent with this hypothesis, while strong ties roughly duplicate the chances of accepting a protest invitation when received by high socioeconomic status (SES) targets, the effectiveness of invitations disappears among low SES targets. This suggests that research about the effects of social networks on protest participation should consider how these networks are embedded in larger socioeconomic structures.
Historical Understanding among Adolescents in a Multicultural Setting

ABSTRACTThe author of this study examines six students' construction of historical knowledge as shaped by school and family. The author explores students' perceptions of the disjunctions and interactions between the two sources of historical understandings. Students representing a range of social studies achievement and ethnic backgrounds were selected from grade 11 classes in a large, urban, multicultural school. Classroom participant-observations and two in-depth interviews with each student provide the data. The students' patterns of historical understanding are analyzed with particular attention to the following elements: historical significance, historical evidence and authority, and historical agency, empathy, and moral judgment.The author suggests that family experiences and other sources of information outside school strongly influence the way in which students understand history. He explores some of the problems generated when the complexities of historical meaning making remain unrecognized in s.
Cultural differences in, and influences on, consumers' propensity to adopt innovations

Purpose – The purpose of this paper is to investigate the relationship between national culture and adoption of new products, ideas, or behaviour to suggest a framework for distinguishing between innovative and imitative behaviour.Design/methodology/approach – The four dimensions propounded by Hofstede are used to distinguish national cultures for developing hypotheses pertaining to patterns of adoption of new products, namely innovative and imitative behaviour of consumers and the sources of influence that instigate them into such behaviours.Findings – Results from the study provide support for some of the hypothesised effects which suggest that indeed, certain dimensions of culture are a key factor in determining whether or not consumers will display a propensity to innovate. Specifically, it was found that cultures characterised by small power distance, weak uncertainty avoidance and masculinity will demonstrate innovativeness. The findings also indicate that consumers coming from different national cu.
Velocity-based CRLB predictions for enhanced cooperative links selection in location-enabled mobile heterogeneous networks

In this paper we consider adapting links selection criteria to assist the localization of Mobile Terminals in heterogeneous and cooperative wireless networks. Integrating asynchronously the velocity and location estimates of neighboring terminals in a performance indicator based on a Cramer Rao Lower Bound, one can reliably anticipate on the instantaneous location estimation errors that would be committed along mobile trajectories, while experiencing limited connectivity. This new dynamic indicator is thus helpful to predict in a reasonably short-term the most relevant combination of range measurements, for instance based on Received Signal Strength Indicators, with respect to other neighboring mobile terminals over peer-to-peer links. The idea is to limit in turn power consumption, computational complexity and latency, for instance by postponing as much as possible a complete refreshment of the serving neighbors. Coupling further this selection scheme with a decentralized and cooperative Extended Kalman Filter, simulation results are provided in a realistic dynamic heterogeneous indoor context, including fixed WiFi Access Points and multi-standard WiFi/Zigbee mobile terminals under pedestrian mobility.
Clinical utility of kallikrein-related peptidases (KLK) in urogenital malignancies

Summary Kallikrein-related peptidases (KLK), which represent a major tissue-associated proteolytic system, stand for a rich source of biomarkers that may allow molecular classification, early diagnosis and prognosis of human malignancies as well as prediction of response or failure to cancer-directed drugs. International research points to an important role of certain KLKs in female and male urogenital tract malignancies, in addition to cancers of the lung, brain, skin, head and neck, and the gastrointestinal tract. Regarding the female/male urogenital tract, remarkably, all of the KLKs are expressed in the normal prostate, testis, and kidney whereas the uterus, the ovary, and the urinary bladder are expressing a limited number of KLKs only. Most of the information regarding KLK expression in tumour-affected organs is available for ovarian cancer; all of the 12 KLKs tested so far were found to be elevated in the malignant state, depicting them as valuable biomarkers to distinguish between the normal and the cancerous phenotype. In contrast, for kidney cancer, a series of KLKs was found to be downregulated, while other KLKs were not expressed. Evidently, depending on the type of cancer or cancer stage, individual KLKs may show characteristics of a Janus-faced behaviour, by either expanding or inhibiting cancer progression and metastasis.
Contributions of Psychophysiology to Media Research: Review and Recommendations

Despite the increasing use of psychophysiological measures in various research areas, there is a relative paucity of studies on communication, media, and media interfaces that have taken advantage of this approach. This article provides an overview of the use of psychophysiological measures of attention and emotion in media research with the focus on 3 most commonly used measures: heart rate, facial electromyography, and electrodermal activity. Selected media studies that have used psychophysiological methods to test theory-based predictions regarding the role of attentional and emotional factors in message processing are critically reviewed. The article also highlights some methodological and other issues critical for the successful application of psychophysiological methods to problems in media research. In particular, respiratory sinus arrhythmia (RSA), a selective index of parasympathetic nervous system activity, is introduced as a measure that holds particular promise for media research, given that RSA is highly sensitive to changes in attention.
Sons, Daughters, and the Risk of Marital Disruption

The association between the sex of children and their parents' risk of marital disruption is examined using the June 1980 Current Population Survey. The finding is that sons reduce the risk of marital disruption by 9% more than do daughters. This difference holds across marriage cohorts, racial groups, and categories of mother's education. A compelling explanation for these findings, supported by data from the National Survey of Children, stresses a father's greater role in raising sons than daughters and his consequently greater involvement in the family. Children provide a new basis for marital cohesion, one that rests on attachments and obligations to children. For fathers, the obligations and attachments are greater if they have sons.
An examination of speech recognition in a modulated background and of forward masking in younger and older listeners.

PURPOSE To compare speech intelligibility in the presence of a 10-Hz square-wave noise masker in younger and older listeners and to relate performance to recovery from forward masking. METHOD The signal-to-noise ratio required to achieve 50% sentence identification in the presence of a 10-Hz square-wave noise masker was obtained for each of the 8 younger/older listener pairs. Listeners were matched according to their quiet thresholds for frequencies from 600 to 4800 Hz in octave steps. Forward masking was also measured in 2 younger/older threshold-matched groups for signal delays of 2-40 ms. RESULTS Older listeners typically required a significantly higher signal-to-noise ratio than younger listeners to achieve 50% correct sentence recognition. This effect may be understood in terms of increased forward-masked thresholds throughout the range of signal delays corresponding to the silent intervals in the modulated noise (e.g., <50 ms). CONCLUSIONS Significant differences were observed between older and younger listeners on measures of both speech intelligibility in a modulated background and forward masking over a range of signal delays (0-40 ms). Age-related susceptibility to forward masking at relatively short delays may reflect a deficit in processing at a fairly central level (e.g., broader temporal windows or less efficient processing).
The cognitive interview and the assessment of the credibility of adults' statements.

The authors examined whether a cognitive interview would negatively affect the accuracy of a criteria-based content analysis (CBCA) in distinguishing truthful and fabricated statements. Adults (N = 59 ) gave a truthful or a fabricated account of a blood-donation episode. They were interviewed with either a cognitive or a structured interview. The number of correct, incorrect, and confabulated details were counted from written transcripts of the accounts. The cognitive interview produced significantly more correct and confabulated details than did the structured interview. The transcripts were further evaluated according to a subset of CBCA criteria plus 6 additional criteria. The content characteristics reliably discriminated truthful and fabricated accounts. No interaction was found between truthfulness and the type of interview, indicating that the cognitive interview did not impair the potential of CBCA in distinguishing truthful and fabricated statements.
Perceptions of restorative justice concepts: an evaluation of university housing residents

This study focuses on the perceptions of students who resided in a university residential hall regarding methods of conflict resolution and concepts of restorative justice. Furthermore, comparisons of perceptions between residents who participated in restorative justice workshops with residents who did not are also made. Variables studied include: understanding the perspectives of others, willingness to approach others, consideration of how to approach others, and awareness of communication styles during conflict situations. Additional considerations include a willingness for inclusion, providing perspectives, and listening and compromising during conflict situations. Also explored is usage of dialogue as well as residents becoming better equipped to approach others, and utilizing or sharing information about restorative justice concepts with others following restorative justice workshops. Findings suggest that residents exposed to restorative concepts during workshops were more likely than non-attenders to listen to the perspectives of others regarding conflict situations. The results indicate that a number of the residents within the university housing setting shared and utilized restorative justice techniques with others following attendance of the restorative workshops.
Separating production from perception: Perceiver-based explanations for sex differences in emotion

Abstract In this commentary, we review evidence that production-based (perceiver-independent) measures reveal few consistent sex differences in emotion. Further, sex differences in perceiver-based measures can be attributed to retrospective or dispositional biases. We end by discussing an alternative view that women might appear to be more emotional because they are more facile with emotion language.
Polarized sorting in epithelial cells: raft clustering and the biogenesis of the apical membrane

Polarized cells establish and maintain functionally distinct surface domains by an elaborate sorting process, which ensures accurate delivery of biosynthetic cargo to different parts of the plasma membrane. This is particularly evident in polarized epithelial cells, which have been used as a model system for studies of sorting mechanisms. The clustering of lipid rafts through the oligomerization of raft components could be utilized for segregating apical from basolateral cargo and for the generation of intracellular transport carriers. Besides functioning in polarized sorting in differentiated cells, raft clustering might also play an important role in the biogenesis of apical membrane domains during development.
