Successive LLR Combining in the Iterative Receiver for MIMO-BICM Systems

In this paper, we propose a new linear detector for the iterative receiver for MIMO-BICM systems. Instead of performing vector matched filtering after the interference cancellation, the proposed detector successively combines the soft information from different receive antennas, where the combining factors are computed based on the joint likelihood function of multivariate Gaussian random variables. Numerical results show that significant performance improvement can be achieved and the additional complexity is negligible.
Activity tracking: are we more than the sum of our programming?

Standard activity trackers preprocess raw personal data from accelerometers and gyroscopes, to provide meaningful results in the form of step counts, calories burned, and progress over time. What happens though, when the built-in algorithms are not calibrated to an individual's physiological characteristics? Specifically, is 16 consecutive days of an activity rating at "-1" a meaningful diagnostic or a data disaster? This paper highlights results from a preliminary study exploring the user experience of persons with chronic disease and/or cognitive disabilities with off-the-shelf wearable activity tracking devices. Results show that though these devices can be useful to determine baselines, trends and deviation in activity, their current one-size-fits-all analytics, coupled with their closed data policies, introduce a significant data disaster for this population.
Spatiotemporal Patterns of Reinfestation by Triatoma guasayana (Hemiptera: Reduviidae) in a Rural Community of Northwestern Argentina

Abstract Triatoma guasayana (Wygodzinsky & Abalos) is a secondary vector of Trypanosoma cruzi (Chagas), the etiologic agent of Chagas disease, in the Chaco region of Argentina, Bolivia, and Paraguay. The spatial distribution of T. guasayana in a rural community in northwestern Argentina is described and analyzed using very high spatial resolution satellite imagery, geographic information systems, and spatial statistics. Since a 1992 residual spraying with insecticides of all houses, site-specific domestic and peridomestic reinfestations by triatomine bugs were monitored using various methods semiannually from 1993 to 2002. The reinfestation by T. guasayana started with finding of only adult bugs in a few sites. Bug abundance was significantly clustered and predominantly peridomestic in the southern and northern extremes of the community. The identified source of reinfestation in the northern cluster was a colonized wood pile, whereas no potential peridomestic source was found for the southern cluster. The spatial distribution of T. guasayana was positively associated with the abundance and spatial distribution of goats. Active dispersal from the hypothesized source and the surrounding sylvatic environment, and passive transport of bugs in wood piles seems to be the most likely mechanisms underlying the observed spatial pattern of T. guasayana. The absence of domestic colonization indicates that, to date, there is no trend toward increased local domiciliation of T. guasayana. The clustering zones can be considered “hot spots” where bug invasion from other sources is expected to be higher and where eventually, introduction of sylvatic T. cruzi to suitable hosts may occur.
Adverse events in New Zealand public hospitals II: preventability and clinical context.

AIMS To assess the preventability and clinical context of adverse events identified in New Zealand public hospitals. METHODS Two-stage retrospective review of 6579 medical records randomly sampled from admissions for 1998 in 13 generalist hospitals providing acute care. Initial screening and medical review according to a standardised protocol. RESULTS Eight hundred and fifty adverse events were identified, of which over one third (315) were preventable to a significant degree. Preventability of events increased with age of patient, and was more characteristic of certain diagnostic categories. Half of all events (413/850) were both preventable and occurred in hospital, giving an occurrence rate of 6.3%. This rate increased with patient age, as did impact on patients and extended stay. There were also variations by diagnostic category. Over half of the events were associated with surgery (489) and one third with medicine (303); operative incidents were predominant in the former, drug-related in the latter, and system issues in both. Events in medicine had greater patient impact, and were less likely to have occurred in a public hospital. System errors featured prominently as an area for prevention, being associated with nearly half of all preventable in-hospital events. Consultation and education were also important, resources less so. CONCLUSIONS Preventable adverse events have a major impact on patient outcomes and extended hospital stay. A substantial proportion of these are system related and, hence, in principle susceptible to quality improvement.
Reduction in Pediatric Rotavirus-related Hospitalizations After Universal Rotavirus Vaccination in Belgium

Background: This study investigated the effect of pediatric vaccination against rotavirus on the number of rotavirus-related hospitalizations of children in Belgium. Methods: This retrospective database study was conducted at 12 pediatric hospitals in Belgium (546 pediatric beds, 30.6% of Belgian total). Children ≤5 years attending hospital for any reason were eligible if they had a rotavirus stool test at one of the study centers. The number of rotavirus-positive stool tests and hospitalizations for acute gastroenteritis (AGE) were compared for prevaccination (June 2004–May 2006) and postvaccination (June 2007–May 2009) study periods. Results: The number of rotavirus-positive stool tests in children who were ≤5 years of age decreased from an average of 881 in the prevaccination period to 368 in the first year postvaccination period and 199 in the second. In children 2 to 24 months of age, the percentage reductions were 65% (95% confidence interval [CI]: 62%, 69%) and 80% (95% CI: 77%, 83%) in the first and second years after vaccination, respectively, compared with prevaccination. In children <2 months, the reductions were 50% (95% CI: 36%, 64%) and 64% (95% CI: 49%, 76%), respectively, and in children >24 months the corresponding values were 20% (95% CI: 14%, 28%) and 64% (95% CI: 56%, 72%). The number of AGE-driven hospital admissions and hospitalization days for AGE declined by 33% and 36%, respectively, from prevaccination to the second year postvaccination in children ≤2 years of age. Conclusions: Pediatric rotavirus vaccination in Belgium significantly reduced rotavirus-related hospitalizations in the first and second years after introduction.
CORPORATE SOCIAL RESPONSIBILITY IN EUROPEAN AND ASIAN COUNTRIES

Abstract : The purpose is to study the two facets of corporate social responsibility (CSR) and their similarities and differences between European and Asian countries in different industries. A survey was conducted in Estonian, Chinese, Finnish, Slovakian and Japanese enterprises. Data about two facets of corporate social responsibility, three different branches and five different countries were compared by applying Lorents’s metrics. The ordered pairs were created for each branch and country priorities separately. The distances between priorities were calculated. The total number of respondents was 4187. CSR is influenced by social and cultural environment and industry where the organisation operates. From two facets of CSR the firm respect the interests of agents is more connected with cultural backround than with economic development. The second facet of CSR - firm performance concerning social issue – is more connected with industry than culture. There could also be other factors like ethics, leadership, innovation influencing corporate social responsibility and its similarities and differences in different countries. Keywords : corporate social responsibility, China, Estonia, Finland, Slovakia and Japan
Loss of the neural integrator of the oculomotor system from brain stem lesions in monkey.

Eye movement were recorded from four juvenile rhesus monkeys (Macaca mulatta) before and after the injection of neurotoxins (kainate or ibotenate) in the region of the medial vestibular and prepositus hypoglossi nuclei, an area hypothesized to be the locus of the neural integrator for horizontal eye movement commands. Eye movements were measured in the head-restrained animal by the magnetic field/eye-coil method. The monkeys were trained to follow visual targets. A chamber implanted over a trephine hole in the skull permitted recordings to be made in the brain stem with metal microelectrodes. The abducens nuclei were located and used as a reference point for subsequent neurotoxin injections through cannulas. The effects of these lesions on fixation, vestibuloocular and optokinetic responses, and smooth pursuit were compared with predicted oculomotor anomalies caused by a loss of the neural integrator. Kainate and ibotenate did not create permanent lesions in this region of the brain stem. All the eye movements returned toward normal over the course of a few days to 2 wk. Histological examination revealed that the cannula tips were mainly located between the vestibular and prepositus hypoglossi nuclei, in their rostral 2 mm, bordered rostrally by the abducens nuclei. Dense gliosis clearly demarcated the cannula tracks, but for most injections there were no surrounding regions of neuronal loss. Thus the eye movement disorders were due to a reversible, not a permanent, lesion. The time constant for the neural integrator was determined from the velocity of the centripetal drift of the eyes just after an eccentric saccade in total darkness. For intact animals this time constant was greater than 20 s. Shortly after bilateral injections of neurotoxin, the time constant began to decrease and reached a minimum of 200 ms; every horizontal saccade was followed by a rapid centripetal drift with a time constant of approximately 200 ms. For vertical eye movements, in this acute phase, the time constant was approximately 2.5 s. The vestibuloocular reflex (VOR) was drastically changed by the lesions. A step of constant head velocity in total darkness evoked a step change in eye position rather than in velocity. In the absence of the neural integrator, the step velocity command from the canal afferents was not integrated to produce a ramp of eye position (normal slow phases); rather this signal was relayed directly to the motoneurons and caused a step in eye position. The per- and postrotatory decay of the head velocity signal was decreased to 5-6 s indicating that vestibular velocity storage was also impaired. (ABSTRACT TRUNCATED AT 400 WORDS)
The pre-mir-499 Variant rs3746444 May Contribute to Coronary Artery Disease Susceptibility: a Case-Control and Meta-Analysis Study.

BACKGROUND Recent reports have suggested that single-nucleotide polymorphisms (SNPs) in microRNA genes may contribute to individual susceptibility to coronary artery disease (CAD). The purpose of this study was to evaluate the association between rs3746444 in pre-miR-499 with CAD. METHODS We performed a case-control study including 288 CAD patients and 150 control subjects. DNA was extracted from blood samples and genotyped through the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. Meta-analysis was performed under fixed effect and random effect models whenever appropriate. RESULTS We found that the GG genotype is significantly more frequent in CAD patients than controls (adjusted p = 0.010; OR = 1.99, 95%; CI: 1.18 - 3.38). Additionally, through a meta-analysis, we showed that miR-499rs3746444 has a significant association with cardiovascular disease. CONCLUSIONS Our results suggest that miR-499-rs3746444-GG is associated with CAD susceptibility and development.
Tulipa gesneriana and Lilium longiflorum PEBP Genes and Their Putative Roles in Flowering Time Control

Floral induction in Tulipa gesneriana and Lilium longiflorum is triggered by contrasting temperature conditions, high and low temperature, respectively. In Arabidopsis, the floral integrator FLOWERING LOCUS T (FT), a member of the PEBP (phosphatidyl ethanolamine-binding protein) gene family, is a key player in flowering time control. In this study, one PEBP gene was identified and characterized in lily (LlFT) and three PEBP genes were isolated from tulip (TgFT1, TgFT2 and TgFT3). Overexpression of these genes in Arabidopsis thaliana resulted in an early flowering phenotype for LlFT and TgFT2, but a late flowering phenotype for TgFT1 and TgFT3. Overexpression of LlFT in L. longiflorum also resulted in an early flowering phenotype, confirming its proposed role as a flowering time-controlling gene. The tulip PEBP genes TgFT2 and TgFT3 have a similar expression pattern in tulip, but show opposite effects on the timing of flowering in Arabidopsis. Therefore, the difference between these two proteins was further investigated by interchanging amino acids thought to be important for the FT function. This resulted in the conversion of phenotypes in Arabidopsis upon overexpressing the substituted TgFT2 and TgFT3 genes, revealing the importance of these interchanged amino acid residues. Based on all obtained results, we hypothesize that LlFT is involved in creating meristem competence to flowering-related cues in lily, and TgFT2 is considered to act as a florigen involved in the floral induction in tulip. The function of TgFT3 remains unclear, but, based on our observations and phylogenetic analysis, we propose a bulb-specific function for this gene.
The Impact of Benchmark Set Composition on Auditors' Level 3 Fair Value Judgments

Auditors frequently use benchmarking analysis to evaluate the appropriateness of a client's estimates. Client management may strategically select benchmark data, making an auditor's evaluation task more difficult. Psychology research suggests that the composition of the benchmark set can lead to contrast effects, because evaluations of an option in a choice set can change based on the inclusion of other options in the set. In Experiment 1, we examine and find that auditors' judgments of the reasonableness of a client-preferred discount rate for a Level 3 investment are inappropriately influenced by the set of peer companies provided by the client as justification. In Experiment 2, audit managers performing the same task similarly exhibited contrast effects. However, as managers' investment experience increased, the influence of contrast effects from the benchmark set decreased. Given the widespread use of benchmark data, contrast effects from benchmark set composition have implications for accounting and auditing contexts.
Inhibition of Na+/Ca2+ exchange in membrane vesicle and papillary muscle preparations from guinea pig heart by analogs of amiloride.

Na+/Ca2+ exchange is inhibited in both guinea pig cardiac membrane vesicles and papillary muscles in a concentration-dependent fashion by several analogs of the pyrazine diuretic amiloride. Structure/activity studies based on transport measurements in vesicles prepared from guinea pig left ventricle indicate that hydrophobic substitutions at the terminal nitrogen atom of the guanidinium moiety of amiloride improved the inhibitory potency almost 100-fold over that of the parent compound. 3',4'- Dichlorobenzamil ( DCB ) is one of the most active inhibitors (IC50 = 17 microM). In electrically stimulated papillary muscles isolated from guinea pig heart, 10-40 microM DCB decreases contractile force. At 100 microM inhibitor, diastolic tension is significantly increased. The positive inotropic responses to veratridine and ouabain are inhibited by 20 and 40 microM DCB . Since the responses to these interventions were a consequence of increased intracellular Na+ concentration, these data indicate that DCB is an inhibitor of Na+-dependent Ca2+ influx in the intact tissue. Interpretation of mechanical responses elicited by paired pulses suggests that 40 microM but not 100 microM DCB decreases release of Ca2+ from the sarcoplasmic reticulum. The mechanical data obtained with concentrations of DCB that inhibited Na+/Ca2+ exchange in vesicles suggest that a significant amount of Ca2+ can enter the cardiac cell via Na+/Ca2+ exchange under normal conditions and that this transport system may be an important source of Ca2+ supplying the sarcoplasmic reticulum in guinea pig heart. Moreover, these amiloride analogs function as potent inhibitors of the positive inotropic effect caused by increased intracellular Na+ concentration.
Suppression of endotoxin-induced renal tumor necrosis factor-alpha and interleukin-6 mRNA by renin-angiotensin system inhibitors.

The present study was designed to clarify the role of angiotensin II (Ang II) in modulating renal tumor necrosis factor (TNF)-alpha and interleukin-6 (IL-6) production and to investigate the effect of one dose of Ang II inhibitor on cytokines production following lipopolysaccharide (LPS) to cause endotoxemia. Two studies were performed: 1) Ang II was infused intravenously at a rate of 0.2 microg/kg per minute for 4 h in rats and then kidneys were collected to assay TNF-alpha and IL-6 mRNA levels; 2) Four-week-old Wistar rats pre-treated with angiotensin-converting enzyme inhibitor, enalapril, or type I Ang II-receptor antagonist, TCV-116, were injected with LPS (0.1, 0.5, 1.0 mg, i.p.), and then 2 or 4 h later, kidneys were collected to assay TNF-alpha, IL-6, renin and angiotensinogen mRNA levels. After a 4-h intravenous infusion of Ang II, renal TNF-alpha or IL-6 mRNA level significantly increased 1.9-fold or 2.1-fold (each P<0.05) to the control level, respectively. LPS stimulated TNF-alpha, IL-6 and angiotensinogen mRNA levels in the kidney but in rats given enalapril or TCV-116, LPS-induced IL-6 and TNF-alpha mRNA levels were completely suppressed (each P<0.05). This suggests that a single dose of renin-angiotensin system inhibitor suppressed renal IL-6 and TNF-alpha production and may prevent cytokine-induced renal damage during endotoxemia.
Amenities, economic opportunities and patterns of migration at the city level in China

This paper used a bootstrapped linear regression model to examine the role of amenities and economic opportunities in migration patterns in China based on the 2010 census at the city level. The results reveal that striking disparities characterize migration at the city level in China. Most migrants tend to move into several major cities in urban agglomerations in the eastern coastal region and provincial inland capitals. The cities farther away from provincial capitals have weak inflows and even suffer from serious population loss. The results suggest that job opportunities and wages contribute to the uneven pattern of migration in China even as amenities have also become important pull factors of migration. Regarding amenities, migrants prefer to move into cities with warm winters, less-humid summers, clean urban environments and friendly and open social climates. Social services, including facilities for education, recreation and commuting, also play an important role in attracting migrants. Findings from the study improve our understanding of China's internal migration and contribute to the debate on the role of economic opportunities and amenities in migration.
Turning Postgraduate Students’ Research Into Publications

The authors attempted to contact all 157 graduates from the University of Auckland’s Master’s in Public Health (MPH) program who completed theses from 1991 to 2005 about publications arising from their research. Of the 104 students contacted, 77 (74%) completed the questionnaire: 34 (45%) submitted a total of 46 articles, 31 (66%) of which were accepted or published. An expectation of publication and being supported financially were both associated with submission for publication. The most commonly reported barriers were lack of time (62%), lack of staff support (35%), and low confidence in ability to write (29%). For those regarding time as a barrier, work demands were commonly cited (90%). Sustained commitment from supervisors plus practical support (seminars, workshops, and cosupervision) was considered likely to be helpful. More effective supervisor–student engagement, funding, and setting an expectation of publication could increase MPH research outputs, but the additional supervisor workload must be realistic.
Cooperative operation based master-slave in islanded microgrid with CPT current decomposition

In multi-inverter-based islanded microgrids with unbalanced and distorted loads, due to voltage drop across line, the load bus voltage is unbalanced and distorted, which shows the requirement for power quality increase at load bus. To address this problem, this paper presents master-slave-based cooperative operation of DGs with the implementation of Conservative Power Theory (CPT), in which in addition to load sharing, load voltage quality is also improved to standard limits. Sharing factors for each current component are determined by a supervisory control considering constraints for instance availability of primary sources, converter rating and structure and switching frequency. The control strategy is implemented in abc frame. This remarkably facilitates the controller design procedure, offering a very flexible, selective and powerful load current sharing scheme for the DG inverter units, and the effectiveness of this scheme is demonstrated through digital simulations conducted by means of PSIM.
Heterogeneous effects of merit scholarships: do program features matter?

ABSTRACT This paper examines the role of program features in determining the effectiveness of merit scholarships on educational outcomes using data from the 2009 to 2014 American Community Survey. Exploiting the variation in the timing of program adoption as well as program features across states, I find that leniency of academic requirements for initial eligibility largely contributes to program effects on associate’s degree completion, whereas generosity of scholarship amount significantly increases college attendance and bachelor’s degree completion. The estimates also indicate that lower requirements for scholarship renewal appear to positively affect the likelihood of completing a degree in science, technology, engineering, and mathematics fields (STEM). The findings suggest that leniency and generosity are important determinants of program effectiveness on educational outcomes. It is thus relevant to take program features into account when designing merit scholarships.
Using tracking technology to improve marketing: insights from a historic town in Tasmania, Australia

ABSTRACT This study examines the movement patterns of different market segments in an historic town. It combines traditional visitor surveys with a bespoke tourist tracking application. Two analytical stages were undertaken. The first involved analyzing the movements of tourist segments and revealed that “heritage” tourists tended to visit for the shortest lengths of time. The second phase revealed that a visit of between one and two hours seemed to provide the best opportunity to explore the village fully, while shorter and longer stays did not. The insights challenge traditional notions that heritage-oriented tourists should form the target market for historic communities.
