Optimal user association in multi-user MIMO Small Cell Networks

Dense Networks and large MIMO are two key enablers to achieve high data rates towards next generation 5G networks. In this context, we study user association in an interference limited Multi-user MIMO Small Cell Network. Extending on our previous findings, we derive explicit expressions for the optimal ratio of the number of antennas at the base station to the number of users that can associate to a base station in such a Network. This expressions are used to compute the actual number of users that can associate for a given interference level and other system parameters. Simulation results and numerical examples are provided to support our theoretical findings.
SOUND BLENDING AND LEARNING TO READ: AN EXPERIMENTAL INVESTIGATION

Summary. 60 4- to 6-year-old children were involved in two experiments, carried out to determine whether training in sound blending facilitates subsequent learning to read. Results showed (i) that children of these ages improved their performance on a sound blending post-test, (ii) that 5- 6-year-olds performed better on a subsequent reading task than children not given sound blending training, and (iii) that 4- 5-year-old girls trained in sound blending performed better on the reading task than similarly trained boys of the same age. Rather than an overall superiority of girls on sound blending and reading, there appeared to be a specific difference between the sexes in response to training.
Potential ameliorators of aflatoxicosis in weanling/growing swine.

Three trials using 207 crossbred pigs were conducted to evaluate the effects of aflatoxin-contaminated corn on young pigs and to determine whether several nutritional and nonnutritional dietary amendments would benefit performance or health in situations of aflatoxin B1 contamination. In Trial 1 using 90 pigs in a 49-d trial, linear (P < .01) and quadratic (P < .05) decreases in ADG were observed with increasing (0, 420, 840 ppb) dietary aflatoxin level. This growth decrease was associated with linear reductions (P < .01) in ADFI and decreases in gain/feed. Serum indicators of protein synthetic capabilities and of liver damage were also adversely affected. Improvements in growth rate for the total trial period in the presence of 840 ppb of aflatoxin were obtained with the addition of the 2 ppm of folic acid (P < .05) or . 5% hydrated sodium calcium aluminosilicate (HSCA) (P < .01); the magnitude of improvement was greater for the HSCA. The addition of HSCA to the contaminated diet also restored the serum clinical chemistry profile to that exhibited by pigs fed the diet without contaminated corn. The addition of . 6 ppm of Se to a basal diet containing . 3 ppm of Se was generally without effect. In Trial 2, 63 pigs were used in a 42-d trial to further assess the effectiveness of both folic acid and HSCA, as well as of two sodium bentonites, in reducing the effects of aflatoxin from naturally contaminated diets (800 ppb of aflatoxin). Folic acid had no positive effect in this trial, but HSCA improved ADG (P < .01) and all clinical chemistry indicators that had been negatively affected by the contaminated diet (P < .05).

Efficiency and Cost of Economical Brain Functional Networks

Brain anatomical networks are sparse, complex, and have economical small-world properties. We investigated the efficiency and cost of human brain functional networks measured using functional magnetic resonance imaging (fMRI) in a factorial design: two groups of healthy old (N = 11; mean age = 66.5 years) and healthy young (N = 15; mean age = 24.7 years) volunteers were each scanned twice in a no-task or “resting” state following placebo or a single dose of a dopamine receptor antagonist (sulpiride 400 mg). Functional connectivity between 90 cortical and subcortical regions was estimated by wavelet correlation analysis, in the frequency interval 0.06–0.11 Hz, and thresholded to construct undirected graphs. These brain functional networks were small-world and economical in the sense of providing high global and local efficiency of parallel information processing for low connection cost. Efficiency was reduced disproportionately to cost in older people, and the detrimental effects of age on efficiency were localised to frontal and temporal cortical and subcortical regions. Dopamine antagonism also impaired global and local efficiency of the network, but this effect was differentially localised and did not interact with the effect of age. Brain functional networks have economical small-world properties—supporting efficient parallel information transfer at relatively low cost—which are differently impaired by normal aging and pharmacological blockade of dopamine transmission.
The RUN Domain of Rubicon Is Important for hVps34 Binding, Lipid Kinase Inhibition, and Autophagy Suppression*

The class III phosphatidylinositol 3-kinase (PI3KC3) plays a central role in autophagy. Rubicon, a RUN domain-containing protein, is newly identified as a PI3KC3 subunit through its association with Beclin 1. Rubicon serves as a negative regulator of PI3KC3 and autophagosome maturation. The molecular mechanism underlying the PI3KC3 and autophagy inhibition by Rubicon is largely unknown. Here, we demonstrate that Rubicon interacts with the PI3KC3 catalytic subunit hVps34 via its RUN domain. The RUN domain contributes to the efficient inhibition of PI3KC3 lipid kinase activity by Rubicon. Furthermore, a Rubicon RUN domain deletion mutant fails to complement the autophagy deficiency in Rubicon-depleted cells. Hence, these results reveal a critical role of the Rubicon RUN domain in PI3KC3 and autophagy regulation.
EXECUTIVE PERSONALITY, CAPABILITY CUES, AND RISK-TAKING: HOW NARCISSISTIC CEOS REACT TO THEIR SUCCESSES AND STUMBLES.

The article examines factors contributing to variations in executives' levels of confidence and proposes that executive confidence is influenced by contextual stimuli but that it is moderated by the executive's decision. The concept of capability cues is presented, which are described as contextual signals that decision makers might interpret as indicators of the current level of overall ability. Capability cues' effect on an executive's interpretation of the riskiness of current decisions is explored. It is shown that boldness is influenced by positive cues while negative cues will induce timidity.
Biochemistry of tropoelastin.

Elastic fibres are an important component of the extracellular matrix and are made of two major components : the more abundant cross-linked elastic protein elastin and the multi-component microfibrils. The biosynthesis of elastic fibres is a complex process involving the interplay of many diverse proteins and genes with elastin as the major component. Tropoelastin is the soluble precursor of elastin and as such it plays a dominant role in elastogenesis. The expression of tropoelastin is under a complex control mechanism, with many isoforms existing. Numerous other components, including the microfibrillar proteins, the elastin-binding protein and lysyl oxidase, the enzyme which initiates elastin cross-linking, are involved in elastogenesis. Tropoelastin undergoes self-association under physiological conditions in a process referred to as coacervation, and this is thought to be a vital process during elastic fibre formation and in providing elasticity. Although various models explaining the elasticity of elastin have been put forward, only the fibrillar model is based on the coacervation ability of tropoelastin. With the molecular cloning of a number of components of the elastic fibre, the availability of these components is increasing and paves the way for in vitro modelling of complex interactions of the elastic fibre. This review emphasises the biochemistry of tropoelastin and its role in elastic fibre structure and assembly.
Publish or Perish?—A Solution in Search of a Problem

Mathews (2007) provides flawed arguments for a solution to a problem which does not demonstrably exist. His solution is just as strange, and bears similarities to an extension of the ‘vanity press’ from books to journal articles. His approach is normative, assumption-laden, and incredibly parochial, but nevertheless entertaining and meriting critical comment. Research resources are spread extremely thinly around most Australian accounting schools; many such schools might have only a handful of active researchers, charged with the responsibility of selling the research message to their colleagues, while at the same time completing the bulk of the associated writing and publication. The productive few may be prolific but, for the majority, outputs may be either non-existent or at the rate of one every two or three years. It is not clear why ‘one article per year’ is ‘desirable’, nor why there should be an ‘increase in output to the level that ought to be taking place’. The material gains from publication are undeniable, especially in terms of promotion, tenure and opportunities for mobility. Parker et al. (1998, p. 381) add weight to this perception with quotations from accounting professors responsible for academic recruitment; in assessing the relative importance of research, teaching, administration and community service in academic appointment and promotion, one interviewee reveals that: ‘Publications is 101 per cent. Everything else is zero’. However, for some, such gains may be less important than the personal pleasure accruing from research success—the pride in one’s own publications and the almost addictive effect that initial success can have on a subsequent publication record. However, Parker et al. (1998) emphasise that it is the quantity and quality, of the research output, which is paramount in demonstrating a research profile, i.e. where you publish is almost more important than what you publish. Sadly, Mathews (2007) is more concerned with counting outputs than measuring quality of contribution. Indeed, his use of the word ‘worthy’ throughout disturbs me; it is almost as if it signifies a good effort by the author in the face of a horrendous teaching load, rather than a piece which adds to our knowledge and understanding. If ‘worthy’ merely signifies ‘worthy Accounting Education: an international journal Vol. 16, No. 3, 259–261, September 2007
Direct Formation of Vaccinia Virus Membranes from the Endoplasmic Reticulum in the Absence of the Newly Characterized L2-Interacting Protein A30.5

ABSTRACT Crescents consisting of a single lipoprotein membrane with an external protein scaffold comprise the initial structural elements of poxvirus morphogenesis. Crescents enlarge to form spherical immature virions, which enclose viroplasm consisting of proteins destined to form the cores of mature virions. Previous studies suggest that the L2 protein participates in the recruitment of endoplasmic reticulum (ER)-derived membranes to form immature virions within assembly sites of cytoplasmic factories. Here we show that L2 interacts with the previously uncharacterized 42-amino-acid A30.5 protein. An open reading frame similar in size to the one encoding A30.5 is at the same genome location in representatives of all chordopoxvirus genera. A30.5 has a putative transmembrane domain and colocalized with markers of the endoplasmic reticulum and with L2. By constructing a complementing cell line expressing A30.5, we isolated a deletion mutant virus that exhibits a defect in morphogenesis in normal cells. Large electron-dense cytoplasmic inclusions and clusters of scaffold protein-coated membranes that resemble crescents and immature virions devoid of viroplasm were seen in place of normal structures. Crescent-shaped membranes were continuous with the endoplasmic reticulum membrane and oriented with the convex scaffold protein-coated side facing the lumen, while clusters of completed spherical immature-virion-like forms were trapped within the expanded lumen. Immature-virion-like structures were more abundant in infected RK-13 cells than in BS-C-1 or HeLa cells, in which cytoplasmic inclusions were decorated with scaffold protein-coated membrane arcs. We suggest that the outer surface of the poxvirus virion is derived from the luminal side of the ER membrane.
The relation between temperament and rate of temporal discounting

The present study examines the relationship between several temperamental traits (sensation seeking, extraversion–introversion, and impulsivity) and rate of temporal discounting, that is the rate of decrease in the subjective value of a reward as the delay to its receipt increases. Participants made choices between hypothetical monetary rewards that could be obtained immediately or after a specified delay. Temporal discounting functions were calculated and differences in rate of discounting between different groups were evaluated. For all groups of participants, hyperbolic discounting functions described well the decreases in subjective value with delay (R2 ranged from 0.700 to 0.985). The rate of discounting was equivalent in high and low sensation seekers. However, both extraverts and high impulsive individuals showed higher temporal discounting rates than introverts and low impulsive individuals. The relationship between temperament and temporal discounting may be related to differences in time perception and/or to differences in susceptibility to rewards in extraverts versus introverts and in high‐ versus low‐impulsive individuals.

Coaches' Immediacy Behaviors as Predictors of Athletes' Perceptions of Satisfaction and Team Cohesion

This study sought to determine whether coaches' immediacy behaviors serve as predictors of athletes' satisfaction and team cohesion levels. Participants included 307 male and female high school athletes who completed measures assessing perceptions of their coaches' verbal and nonverbal immediacy behaviors, as well as their own levels of satisfaction and cohesion. Overall, results indicated that immediacy behaviors accounted for between 9% and 19% of the variance attributed to athletes' satisfaction and team cohesion levels. Specifically, hierarchical regression analysis indicated that coaches' verbal immediacy emerged as the only significant predictor of athletes' satisfaction in their sport, after accounting for athlete playing status and team success. Likewise, the results indicated that coaches' verbal immediacy behaviors were significant predictors of three of the four dependent measures of team cohesion, while perceived nonverbal immediacy behaviors emerged as a predictor for social attraction to group, and were the only significant predictor of task group integration. Discussion focuses on the implications, both empirical and theoretical, for how findings related to coach–athlete interaction can be used to advance our understanding of instructional communication.
Automatic Construction of Japanese KATAKANA Variant List from Large Corpus

This paper presents a method to construct Japanese KATAKANA variant list from large corpus. Our method is useful for information retrieval, information extraction, question answering, and so on, because KATAKANA words tend to be used as "loan words" and the transliteration causes several variations of spelling. Our method consists of three steps. At step 1, our system collects KATAKANA words from large corpus. At step 2, our system collects candidate pairs of KATAKANA variants from the collected KATAKANA words using a spelling similarity which is based on the edit distance. At step 3, our system selects variant pairs from the candidate pairs using a semantic similarity which is calculated by a vector space model of a context of each KATAKANA word. We conducted experiments using 38 years of Japanese newspaper articles and constructed Japanese KATAKANA variant list with the performance of 97.4% recall and 89.1% precision. Estimating from this precision, our system can extract 178,569 variant pairs from the corpus.
The cost efficiency of water utilities: when does public ownership matter?

ABSTRACT This study explores the impact of different ownership types on the efficiency of water utilities. Theories and evidence have shown a puzzling relationship between ownership and performance. Moreover, relatively recent contributions (Andrews et al. 2011) have argued that this relationship can be further convoluted by the effect of organisational and environmental variables. The current study aims to contribute to this literature by providing some empirical evidence for Italy, by proposing a methodology that combines non-parametric efficiency estimation and cluster analysis. Our main findings indicate that privately owned utilities indirectly controlled by a public organisation reach the highest level of efficiency but, when size and geographical location enter the analysis, ownership has a stronger significant effect on efficiency, and mixed utilities gain higher cost efficiency. Therefore, we may conclude that administrative reforms about privatisation and the institutional setting should consider a set of variables that characterise each individual organisation.
EDUCATIONAL GAMES: A TECHNIQUE TO ACCELERATE THE ACQUISITION OF READING SKILLS OF CHILDREN WITH LEARNING DISABILITIES

This study evaluated the effects of educational games on the performance of eight elementary school students with learning disabilities. The effects of educational games were evaluated in a multiple baseline design across students. The results indicated that each student improved their performance on reading when educational games were in effect. These differences were also educationally significant. Practical considerations and implications of educational games for adoption in the classroom were discussed. Learning to read can be a discouraging experience for children who have difficulty grasping concepts and skills. Such students may need practice in order to master what some children do after one trial. Carnine, Silbert, Kameenui, and Tarver (2004) have postulated the more highly motivated a remedial reader is, the greater the student's success. Unmotivated students will not receive the benefit of increased instructional time, careful teaching, and a well-designed program. These children may become discouraged with difficulties they encounter in their reading experiences. Unless some element of fun is introduced along with instruction such students may become bored and turned-off. (Koran & McLaughlin, 1990). Games may relieve the drudgery of drill (Baker, Herman, & Yeh, 1981; Koran & McLaughlin, 1990) and can introduce an element of fun helping to motivate the learning disabled child. Among those supporting the role of educational games in the learning process has been Harris (1968). Harris noted that many kinds of drill, disguised as games become play rather than distasteful drill and practice. Golick (1973) felt that for those children who need more time and extra help to master a skill there is the challenge to find activities that are novel and interesting. Ginsburg and Opper (1972), that children take and active part in the learning process. Through games that they play, they practice the skills they are in the process of learning. This, Golick says, is an important aspect of play and subsequently of games. The first part of this study was designed to determine if poor readers' acquisition of consonant digraphs and consonant blends could be accelerated when teacher instruction was combined with educational games. The second part of the study evaluated the effects of educational games on elementary students' acquisition of vowel variable skills.
Growth in the first two years of uninfected children born to HIV-1 seropositive mothers

OBJECTIVE To assess the growth curves of uninfected infants born to type 1 human immunodeficiency virus (HIV-1) seropositive mothers by means of standardised anthropometric indices. METHODS The z scores (National Center for Health Statistics–World Health Organisation data) of weight for age, length for age, and weight for length of 92 uninfected full term infants born to HIV positive mothers were compared with those of 65 bottle fed full term infants born to healthy mothers at 0, 1, 2, 3, 4, 6, 9, 12, 18, and (in a subgroup) 24 months of age. Confounders were also recorded. RESULTS The study population had a lower length for age z score at birth (95% confidence intervals (CI): 0.02, −0.58) and higher weight for length z scores at 1 (95% CI: 0.21, 0.63), 2 (95% CI: 0.25, 0.66), and 3 (95% CI: 0.0, 0.48) months compared with the reference group. After a temporary recovery, the length for age z score difference increased progressively from the 4th month onwards and was significant at 18 (95% CI: −0.31, −1.05) and 24 (95% CI: −0.02, −0.91) months. The difference between the length for age z scores at birth was associated with maternal covariates, but the between group difference at 18 months was apparent even after adjustment for covariates. CONCLUSION Uninfected infants born to HIV positive mothers have a rapid weight gain immediately after birth. A decrease in length progression during the second year might be a result of the social risk connected with the family environment and an unfavourable programming related to the maternal HIV status.
The Relationship between Dimensions of Physical Abuse and Aggressive Behavior in a Child Protective Services Involved Sample of Adolescents

Although a relationship between harshness of childhood physical abuse and later aggression is well documented, researchers have rarely examined this association using information from the victim’s perspective. Also, no study has controlled for the possibility that victims of harsh abuse are aggressive because they often require more invasive child protection services (CPS), and thus experience greater disruptions to their home situation. A sample of maltreated adolescents completed the Childhood Experiences of Violence Questionnaire, and a year later, answered questions on aggression. Controlling for other subtypes of maltreatment, number of moves, length of CPS involvement, and household situation, we found that frequency of physical abuse and frequency of severe physical abuse were predictive of aggressiveness. These associations remained statistically significant for females but not for males. Indicators of maltreatment chronicity, age of onset, and poly-victimization were not associated with aggression.
A Quantitative Genetic Model for Analyzing Species Differences in Outcrossing Species

Summary. A genetic model based on a two‐level intra‐ and interspecific mating design is proposed to estimate the genetic architecture of species differences and heterosis for outcrossing species. The underlying genetic analyses make use of classical quantitative genetic theories and recent results from molecular genetic studies. Gene effects across different quantitative trait loci (QTL) can be approximated by a geometric series. Under natural selection, gene effects are often associated with allele frequencies in a particular way, which can be approximated by the gamma distribution. By incorporating these approximations into family structural analyses in the mating design, we are able to estimate a number of genetic parameters that contribute to quantitative genetic variation based on a nonlinear optimization approach. These parameters include the number of QTL, their gene effects, and their allele frequencies in the parental populations. We perform simulation studies and illustrate an example to demonstrate the statistical property and procedure of the method.
