Robust Precoding With Limited Feedback Design Based on Precoding MSE for MU-MISO Systems

For the separation of the signals in the vector broadcast channel (BC), some information about the channel state is necessary at the transmitter. In many cases, this channel state information (CSI) must be fed back from the receivers to the transmitter. We jointly design the channel estimators and the quantizers at the receivers together with the precoder at the transmitter based on a precoder-centric criterion, i.e., the minimization of a mean square error (MSE) metric appropriate for the precoder design. This is in contrast to our previous works, where the quantizer design was based on a CSI MSE metric, i.e., based on the minimization of the MSE between the true channel and the channel recovered by the transmitter using a feedback channel. Interestingly, the estimators resulting from this joint formulation are independent of the used codebook. The codebook entries are the employed precoders. Therefore, each receiver feeds back the index of a set of precoders and the intersection of the sets gives the appropriate precoder. Since the quantizers of the different receivers have to work separately, the metric for the computation of the partition cells cannot be expressed as a simple squared error depending on the quantizer output. The proposed system based on a joint optimization clearly outperforms previous designs with separate optimization of feedback and precoding.
Consent reconsidered; reframing consent for ubiquitous computing systems

The developing complexity and decreasing visibility of pervasive computing systems, coupled with increasing value and sensitivity of personal data, mean that it is no longer sufficient to design systems that assume users capable of making informed decisions at a single moment. In particular, the unprecedented sensitivity of contextual data, and the potential harms associated with inferences made on the basis of that data, highlights the need to revisit our design principles in respect of consent. This thesis will use a mixed-methods approach to reframe 'consent' for ubiquitous computing systems, resulting in a series of design guidelines to inform future developments.
Evaluating ethical decision making and computer use

The authors present the results of an exploratory survey identifying users' attitudes and behavior when computer privacy and resource-ownership situations are encountered. T HE Theory of Reasoned Action (TRA), frequently used to describe ethical decision-making behavior, relates attitudes and social norms to individual behavioral intentions [2, 17]. The components of this theory appear to be present in ethical decision situations [11], but they may be insufficient in their usual characterizations to completely describe an ethical decision process [17, 18]. Computer users face an increasing number of ethical dilemmas in their use of computers, and novel situations appear with each new technology. This article presents an exploratory evaluation of the TRA and extensions to attempt to better understand ethical decisions in computer use.
Discovering Similar Users on Twitter

This work studies the problem of discovering \similar" users at Twitter, where we dene two users to be similar if they produce content similar to each other. The discovery of top similar accounts for each Twitter user has a variety of applications at Twitter including user recommendations and advertiser targeting. Although the discovery of similar results is a well studied problem in information retrieval, the particular problem at Twitter has three novel challenges. The rst one is the heterogenous mix of signals that an effective technique could use: content analysis, social graph structure, user popularity, user interaction data etc. It is apriori unclear how could one blend all these dierent signals in an eective manner. Second, any technique needs to work eectively with very dierent kinds of users. This implies that the same framework needs to be applicable to users with millions of followers and users with very few or no followers. Finally, any proposed technique needs to be able to scale such that it can discover similar users for hundreds of millions of users, while keeping up with the highly dynamic nature of all the input signals. In this work, we share the machine learning based framework that we use to discover similar users at Twitter. We also evaluate the eectiveness of the framework on Twitter data.
An adaptive WPE multiuser detector

Weighted polynomial expansion (WPE) detectors can be used to approximate linear multiuser detectors to avoid the need to compute matrix inversion. For finite stage WPE detectors, weight vector optimization is an important process since it determines how effective the linear multiuser detectors can be approximated. In this letter, the optimal weight vector for the finite stage WPE detector is derived based on the mean-squared error (MSE) criteria. In addition, a low-complexity adaptive WPE detector based on the least-squares criteria is proposed to simplify the computation of the optimum weight vector. Simulation results show that the proposed adaptive WPE detector outperforms the existing WPE method.
Investigation of Snow Cover Effects and Attenuation Correction of Gamma Ray in Aerial Radiation Monitoring

In aerial radiation monitoring (ARM), the air dose rate cannot be appropriately estimated under snowy conditions due to attenuation of gamma rays by the snow layer. A technique to address this issue is required for ARM to obtain enough signals for air dose rates. To develop this technique, we investigated the relationship between snow depth and ARM measurement results using ARM, laser imaging detection and ranging, and ground measurement before and after snowfall. From the measured data, the results obtained using three different correction factors were examined and compared. An appropriate correction improved the underestimation of the air dose rate. However, further improvement in the accuracy of the analysis requires accurate estimation of the snow water equivalent.
Floer homology in symplectic geometry and in mirror symmetry

In this article the authors review what the Floer homology is and what it does in symplectic geometry both in the closed string and in the open string context. In the first case, the authors will explain how the chain level Floer theory leads to the C0 symplectic invariants of Hamiltonian flows and to the study of topological Hamiltonian dynamics. In the second case, the authors explain how Floer�fs original construction of Lagrangian intersection Floer homology is obstructed in general as soon as one leaves the category of exact Lagrangian submanifolds. They will survey the construction of the Floer complex and describe its obstruction in terms of the filtered A��-algebras. This can be promoted to the level of A��-category (Fukaya category) of symplectic manifolds. Some applications of this general machinery to the study of the topology of Lagrangian embeddings in relation to symplectic topology and to mirror symmetry are also reviewed.
Spatial characteristics of sarcoplasmic reticulum Ca2+ release events triggered by L‐type Ca2+ current and Na+ current in guinea‐pig cardiac myocytes

Ca2+ signals in cardiac muscle cells are composed of spatially limited elementary events termed Ca2+ sparks. Several studies have also indicated that Ca2+ signals smaller than Ca2+ sparks can be elicited. These signals have been termed Ca2+ quarks and were proposed to result from the opening of a single Ca2+ release channel of the sarcoplasmic reticulum. We used laser‐scanning confocal microscopy to examine the subcellular properties of Na+ current (INa)‐ and L‐type Ca2+ current (ICa,L)‐induced Ca2+ transients in voltage‐clamped ventricular myocytes isolated from guinea‐pigs. Both currents, INa and ICa,L, evoked substantial, global Ca2+ transients. To examine the spatiotemporal properties of such Ca2+ signals, we performed power spectral analysis of these Ca2+ transients and found that both lacked spatial frequency components characteristic for Ca2+ sparks. The application of 10 μm verapamil to partially block L‐type Ca2+ current reduced the corresponding Ca2+ transients down to individual Ca2+ sparks. In contrast, INa‐induced Ca2+ responses were still spatially homogeneous and lacked Ca2+ sparks even for small current amplitudes. By using high resistance patch pipettes (> 4 MΩ) to exaggerate the loss of voltage control during INa, Ca2+ sparks appeared superimposed on a homogeneous Ca2+ release component and were exclusively triggered during the flow of INa. In the presence of 10 μm ryanodine both ICa,L and INa elicited small, residual Ca2+ transients that were spatially homogeneous but displayed distinctively different temporal profiles. We conclude that INa is indeed able to cause Ca2+ release in guinea‐pig ventricular myocytes. In contrast to ICa,L‐induced Ca2+ transients, which are built up from the recruitment of individual Ca2+ sparks, the INa‐evoked cellular responses were always homogeneous, indicating that their underlying elementary Ca2+ release event is distinct from the Ca2+ spark. Thus, INa‐induced Ca2+ transients are composed of smaller Ca2+ signals, most likely Ca2+ quarks.
Empowered parents: the role of self-efficacy in parental mediation of children’s smartphone use in the United States

ABSTRACT This study examines how different types of self-efficacy – media competency, perceived parenting abilities, and perceived control over parental mediation practices – influence the extent to which parents mediate their children’s use of smartphones. A survey conducted with parents of young smartphone users aged 10–17 in the United States (N = 304) reveals that parents who feel confident about their own smartphone skills view themselves as good parents and believe that they have control over their parental mediation practices and are more likely to engage in parental mediation of children’s smartphone use. The findings also indicate that when parents are less confident about their smartphone skills, those with higher parenting competencies are more likely to engage in discussion-based active mediation than those with lower parenting competencies.
Communication Energy Overhead of Mobiles Games

Although a significant proportion of the mobile apps are games there has been little attention paid to their specific characteristics with respect to communication energy. In this paper we select 20 mobile games among the top 100 free Android games, and study their data patterns and communication energy use over a total of 25 hours of playing. The analysis of the energy for communication over 3G networks indicates that there is a wide variation among the games, the largest footprint being 8 times higher than the lowest one. The results also indicates both app-specific and category-specific relations between data pattern and energy use, as well as variations in CPU utilisation.
Incorporating prior knowledge into Gene Network Study

MOTIVATION A major goal in genomic research is to identify genes that may jointly influence a biological response. From many years of intensive biomedical research, a large body of biological knowledge, or pathway information, has accumulated in available databases. There is a strong interest in leveraging these pathways to improve the statistical power and interpretability in studying gene networks associated with complex phenotypes. This prior information is a valuable complement to large-scale genomic data such as gene expression data generated from microarrays. However, it is a non-trivial task to effectively integrate available biological knowledge into gene expression data when reconstructing gene networks. RESULTS In this article, we developed and applied a Lasso method from a Bayesian perspective, a method we call prior Lasso (pLasso), for the reconstruction of gene networks. In this method, we partition edges between genes into two subsets: one subset of edges is present in known pathways, whereas the other has no prior information associated. Our method assigns different prior distributions to each subset according to a modified Bayesian information criterion that incorporates prior knowledge on both the network structure and the pathway information. Simulation studies have indicated that the method is more effective in recovering the underlying network than a traditional Lasso method that does not use the prior information. We applied pLasso to microarray gene expression datasets, where we used information from the Pathway Commons (PC) and the Kyoto Encyclopedia of Genes and Genomes (KEGG) as prior information for the network reconstruction, and successfully identified network hub genes associated with clinical outcome in cancer patients.

Nasometric Measurement and the Classification of Resonance Disorders: Equipment Evaluation and a Tentative Classification System

Resonance disorders due to cleft palate and other aetiologies are frequently assessed in conjunction with nasometry. The most commonly used instrument is the Nasometer by KayPentax. A new model Nasometer 6450 was compared to an older model 6200 using both synthetic and speech stimuli. There was a particular focus on test-retest variability of the instrument. The Nasometers were found to yield comparable results. The inter session test-retest variability ranged from six to eight points, depending on the stimulus. The Nasometer 6450 was then used to collect nasalance scores of simulated resonance disorders. A discriminant analysis was applied to these scores. The resultant formulas were moderately successful in predicting perceived resonance when applied to pre-existing data sets.
KOREAN FEMALE BODY IMAGE VS AMERICAN FEMALE BODY IMAGE REPRESENTED IN THE PRINT MEDIA

Through magazine advertising, the ideal body image represented in the U.S. media has affected people in other parts of the world. The idea of body dissatisfaction, which was at one time only common in Western culture, has spread to South Korea, and other cultures that are influenced by Confucianism. This ideal body image represented in the U.S. media is even more harmful to women from South Korea, because this image is unattainable by natural means. This study looks at different literature dealing with the affects of magazine reading among women in the U.S. and South Korea. This study found that there was greater body dissatisfaction among Korean women, but there wasn't enough evidence to suggest that this was a direct result of women's magazine reading. ii ACKNOWLEDGEMENTS First, I would like to thank Jesus for all that He has done.

Democratic incumbent resilience in the post-1980 Senate

In the period since the Reagan revolution that disrupted decades of Democratic control of the United States Senate, Democratic senators have proved remarkably resilient when running for reelection. Over the past 600 Senate elections since 1980, Republican incumbents have been defeated at more than twice the rate of Democrats, but won open seat elections at a significantly higher rate. This partisan disparity also appears in incumbent vote share, and is statistically and substantively robust to a range of model specifications accounting for existing theories. A series of explanations drawn from existing research explored in this paper fail to explain this trend, suggesting the need for future research targeting partisan differences in perceptions of parties in Senate campaigns.
Financing Strategy, Shareholder Value Creation Over Firms Life Cycle

In this paper, we investigate on the capital structure especially on the external finance source. We also try to find out the correlation between the leverage and the shareholder value creation. We focus our study on the corporate life cycle that is nowadays very used in finance work. The paper employs the comparative analysis and the statistical technique of Pearson's correlation analysis. We find that the start-up and growth firms in their financing strategy rely on the equity financing. Inversely mature firms rely on debt financing. Moreover we have found for the start-up firms, there is a positive correlation between the shareholder value creation and the financial leverage though the magnitude of the relation is very small while for the growth firms and mature firms the relationship turns to be the inverse. We draw the conclusion that the overall objective when designing the optimal mixture of financing instruments is to keep investors and lenders satisfied. Lenders would want companies to issue equity because it makes them safer. Shareholders would want companies to issue more debt because it disciplines managers to effectively manage the corporation in a way to ensure value creation.
Inclusion for a Student with Vision Impairment: “They accept me, like, as in I am there, but they just won’t talk to me.”

We explore the experiences of Nick, a secondary school student with vision impairment in an Australian mainstream school in this study, and we particularly focus on whether he perceived his education as inclusive. We have used Interpretative Phenomenological Analysis in this single individual case as this approach explores our participant’s understandings which may be revealed by close examination of mindful experiences. The “gem” spoken by Nick (pseudonym), our 16-year old participant, was “They accept me, like as in I am there, but they just won’t talk to me. ” This statement summarises his sense of not belonging, of being other, and of being bullied. The inability of his school to provide an inclusive education was apparent to him, and his often-unfulfilled need for access to specialist teachers of vision impairment is explored. Our study includes vivid quotes from Nick to bring his voice to our phenomenological interpretation.
On Dynamic Evolution of Industry Agglomeration Based on Swarm Intelligence

Defects of linear and circular models on industry agglomeration have been illustrated in this paper, with the conclusion that the defects lie in the improper prerequisite of the models, which will lead to false identification of the fundamental impetus of the phenomenon. A dynamic evolution model on industry agglomeration based on swarm intelligence is set up, followed with relevant computer simulation, leading to the finding that the accumulation and diffusion of knowledge is the prime motivation of industry agglomeration.
A Wearable Camera Detects Gaze Peculiarities during Social Interactions in Young Children with Pervasive Developmental Disorders

We report on the study of gazes, conducted on children with pervasive developmental disorders (PDD), by using a novel head-mounted eye-tracking device called the WearCam. Due to the portable nature of the WearCam, we are able to monitor naturalistic interactions between the children and adults. The study involved a group of 3- to 11-year-old children ( n=13) with PDD compared to a group of typically developing (TD) children ( n=13) between 2- and 6-years old. We found significant differences between the two groups, in terms of the proportion and the frequency of episodes of directly looking at faces during the whole set of experiments. We also conducted a differentiated analysis, in two social conditions, of the gaze patterns directed to an adult's face when the adult addressed the child either verbally or through facial expression of emotion. We observe that children with PDD show a marked tendency to look more at the face of the adult when she makes facial expressions rather than when she speaks.
