The Stellar Populations of Praesepe and Coma Berenices

We present the results of a stellar membership survey of the nearby open clusters Praesepe and Coma Berenices. We have combined archival survey data from the SDSS, 2MASS, USNOB1.0, and UCAC-2.0 surveys to compile proper motions and photometry for ∼5 million sources over 300 deg2. Of these sources, 1010 stars in Praesepe and 98 stars in Coma Ber are identified as candidate members with probability >80%; 442 and 61 are identified as high-probability candidates for the first time. We estimate that this survey is >90% complete across a wide range of spectral types (F0-M5 in Praesepe, F5-M6 in Coma Ber). We have also investigated the stellar mass dependence of each cluster's mass and radius in order to quantify the role of mass segregation and tidal stripping in shaping the present-day mass function and spatial distribution of stars. Praesepe shows clear evidence of mass segregation across the full stellar mass range; Coma Ber does not show any clear trend, but low number statistics would mask a trend of the same magnitude as in Praesepe. The mass function for Praesepe (τ ∼ 600 Myr; M ∼ 500 M⊙) follows a power law consistent with that of the field present-day mass function, suggesting that any mass-dependent tidal stripping could have removed only the lowest mass members (<0.15 M⊙). Coma Ber, which is younger but much less massive (τ ∼ 400 Myr; M ∼ 100 M⊙), follows a significantly shallower power law. This suggests that some tidal stripping has occurred, but the low-mass stellar population has not been strongly depleted down to the survey completeness limit (∼0.12 M⊙).
Subconscious Crowdsourcing: A feasible data collection mechanism for mental disorder detection on social media

Mental disorders are currently affecting millions of people from different cultures, age groups and geographic regions. The challenge of mental disorders is that they are difficult to detect on suffering patients, thus presenting an alarming number of undetected cases and misdiagnosis. In this paper, we aim at building predictive models that leverage language and behavioral patterns, used particularly in social media, to determine whether a user is suffering from two cases of mental disorder. These predictive models are made possible by employing a novel data collection process, coined as Subconscious Crowdsourcing, which helps to collect a faster and more reliable dataset of patients. Our experiments suggest that extracting specific language patterns and social interaction features from reliable patient datasets can greatly contribute to further analysis and detection of mental disorders.
Effects of Repeated Reading and Rhyming Poetry on Reading Fluency

: This study tested two instructional methods meant to improve elementary students’ automaticity, phonemic awareness, oral fluency, and reading comprehension. Twelve 1 st grade students received either repeated reading or rhyming poetry instruction. A matched group design was used, and then a single subject analysis was employed to determine if either of the methods was associated with improvements in students’ reading achievement, oral reading fluency, and attitudes towards reading. Findings indicated that students who experienced the rhyming poetry intervention tended to show greater improvements in reading comprehension and oral reading fluency, while those exposed to repeated reading showed mixed results. Students from both conditions showed similar improvements in attitude toward reading, though those in the rhyming poetry group showed slightly more improvement in the area. Overall results suggest that both methods may be beneficial to students’ reading but that rhyming poetry instruction may have greater potential for students at this level. multiple regression analysis conducted. The researchers concluded that attention in good with adequate grade level reading skills, is associated with reading speed, prosody, reading comprehension and word recognition. These findings illustrate the relationship between reading fluency and reading comprehension. knowledge and word recognition and a causal relationship between word recognition and fluency. The study findings suggest that phonics knowledge does contribute to word recognition growth. The finding of the study also indicates that word recognition growth has a casual impact on reading fluency and that phonics and word recognition appear to be a precursor for reading fluency and comprehension. The findings from both studies suggest that phonics instruction seems to be an important aspect to teach reading fluency.

Interacción entre conectores y conocimiento previo en el procesamiento de la coherencia causal

El presente estudio tuvo por objetivo determinar el efecto de los conectores en la eficiencia del procesamiento de relaciones de coherencia causal en lectores con diversos grados de conocimiento previo. Se implementó un experimento con estudiantes universitarios de una misma área disciplinar utilizando el paradigma de lectura autocontrolada con ventana cumulativa y combinando mediciones en línea (tiempos de lectura) y fuera de línea (precisión en una tarea de verificación). Para controlar su grado de conocimiento previo, los participantes fueron agrupados según el paradigma Experto-Novato dependiendo del año de estudios en el que se encontraban. Nuestros datos muestran, a nivel general, que, pese a que los conectores causales incrementan los tiempos de lectura, facilitan una comprensión más profunda. En cuanto a la comparación entre grupos, si bien nuestros datos no muestran diferencias entre ellos, revelan el mismo patrón general. Estos datos sugieren que, al menos en entornos especializados, los conectores desencadenan una lectura intencionada, lo que en el caso de lectores con alto grado de conocimiento disciplinar, como los de nuestro estudio, involucra que los recursos cognitivos son utilizados para asegurar una comprensión profunda. Asimismo, nuestros datos sugieren que una lectura más veloz, no necesariamente asegura la construcción de una representación mental coherente.
Efficient cooperative relaying in wireless multi-hop networks with commodity WiFi hardware

In wireless multi-hop networks, cooperative relaying exploits temporal and spatial diversity by additionally transmitting via a relay node and then combining direct and relay transmissions at the receiver. While such relaying improves packet error rates, it also costs an extra transmission. Along multi-hop paths, there often are nodes that can be a relay for multiple consecutive transmissions. This allows such a relay to transmit only once rather than on each individual hop along the routing path. We show by simulations that cooperative relaying is more efficient in multi-hop networks than in isolated three-node configurations. We compare our simulation to experimental results by implementing our multi-hop cooperation protocol on commodity Wi-Fi hardware. The appeal of using Wi-Fi is its wide availability. However, today's devices were not designed with cooperation protocols in mind. We explain the necessary steps to implement wireless cooperation protocols, using our multi-hop cooperation protocol as an example.
Molecular classification of non-invasive breast lesions for personalised therapy and chemoprevention

Breast cancer screening has led to a dramatic increase in the detection of pre-invasive breast lesions. While mastectomy is almost guaranteed to treat the disease, more conservative approaches could be as effective if patients can be stratified based on risk of co-existing or recurrent invasive disease. Here we use a range of biomarkers to interrogate and classify purely non-invasive lesions (PNL) and those with co-existing invasive breast cancer (CEIN). Apart from Ductal Carcinoma in situ (DCIS), relative homogeneity is observed. DCIS contained a greater spread of molecular subtypes. Interestingly, high expression of p-mTOR was observed in all PNL with lower expression in DCIS and invasive carcinoma while the opposite expression pattern was observed for TOP2A. Comparing PNL with CEIN, we have identified p53 and Ki67 as predictors of CEIN with a combined PPV and NPV of 90.48% and 43.3% respectively. Furthermore, HER2 expression showed the best concordance between DCIS and its invasive counterpart. We propose that these biomarkers can be used to improve the management of patients with pre-invasive breast lesions following further validation and clinical trials. p53 and Ki67 could be used to stratify patients into low and high-risk groups for co-existing disease. Knowledge of expression of more actionable targets such as HER2 or TOP2A can be used to design chemoprevention or neo-adjuvant strategies. Increased knowledge of the molecular profile of pre-invasive lesions can only serve to enhance our understanding of the disease and, in the era of personalised medicine, bring us closer to improving breast cancer care.
Dynamic channel assignment in mobile communications based on genetic algorithms

We investigate dynamic channel assignment (DCA) in mobile communications systems using genetic algorithms (GA). Two new strategies using GA are proposed. In the first strategy, GAL, channels previously assigned are kept locked during the call holding time. In the second strategy, GAS, calls can be switched to different channels during the connection time. We evaluate the performance of the proposed GAs in a 49 hexagonal cell arrangement operating under uniform and nonuniform traffic distributions. Numerical results show that the average call blocking probability of the GAS strategy is lower than that of fixed channel assignment with a borrowing directional channel-locked(BDCL) scheme and of DCA based on Q-learning. The performance of the GAL strategy is better than Q-learning-based DCA for all the investigated cases.
PEDAGOGIK LITERASI KRITIS ; SEJARAH, FILSAFAT DAN PERKEMBANGANNYA DI DUNIA PENDIDIKAN

Makalah ini bertujuan untuk menganalisis konsep pedagogik literasi kritis, mulai dari sejarah, pemikiran para filsuf, dan perkembangannya di dunia pendidikan dewasa ini. Penelitian ini dilatarbelakangi oleh masih jarangnya pembahasan literasi sebagai kekuatan pengubah struktur sosial, pendidikan literasi kritis dapat membantu siswa untuk menandai dan mengurai beragam teks yang merepresentasikan marjinalisasi sosial, penyalahgunaan kekuasaan, ketidakadilan, penindasan, isu ras, isu gender, dan beragam kesenjangan sosial lainnya. Pendidikan literasi kritis akan membantu siswa menjadi agensi untuk mengubah realitas sosial yang kurang memihak. Metode penelitian yang digunakan adalah analisis konsep dengan desain analisis generik (McMillan & Schumacher, 2001) atau integrative review (Whittemore and Knafl 2005). Hasil dari penelitian menunjukkan bahwa sejarah literasi kritis dimulai dari pemikiran Paulo Freire, seorang pedagog dari Brazil yang banyak membawa perubahan di dunia pendidikan melalui pemikirannya tentang konsep literasi sebagai aktivitas membaca kata dan dunia, literasi kritis juga dianggap sebagai kekuatan sosial (Gramsci), perjuangan emansipasi wanita (Ajayi), Agensi dan pemecahan masalah sosial (Hendriani dkk). Penelitian ini memiliki signifikansi untuk memperkaya khazanah pedagogik pada umumnya, khususnya pedagogik kritis pada lingkup pendidikan literasi. Implikasi dari penelitian ini adalah untuk pengembangan pendidikan berbasis literasi kritis pada jenjang pendidikan dasar sampai pendidikan tinggi. This paper aims to analyze the concept of critical literacy pedagogy, from history, philosophers' thinking, and its development in the world of education today. This research is motivated by the rarely discussed literacy as a power to change social structure, critical literacy education can help students to mark and parse various texts representing social marginalization, abuse of power, injustice, oppression, racial issues, gender issues, and various other social inequalities. Critical literacy education will help students become an agency to change the impartiality of social reality. The research method used is concept analysis with generic analysis design (McMillan & Schumacher, 2001) or integrative review (Whittemore and Knafl 2005). The results of the research indicate that the history of critical literacy begins with the thought of Paulo Freire, a Brazilian pedagogue who brought much change in the world of education through his thoughts on the concept of literacy as the activity of reading the word and the world, critical literacy also regarded as social forces (Gramsci), the struggle for emancipation women (Ajayi), Agency and social problem solving (Hendriani et al). This study has significance to enrich the pedagogic treasures in general, especially critical pedagogy on the scope of literacy education. The implications of this research are for the development of critical literacy-based education at the elementary to higher education level.
RELEASES OF IRRADIATED MOTHS TO SUPPRESS WILD POPULATIONS OF ELDANA SACCHARINA WALKER (LEPIDOPTERA: PYRALIDAE)

Pilot shade house trials were conducted to measure the impact of sustained releases of partially sterile adult males of the stalk borer Eldana saccharina Walker (Lepidoptera: Pyralidae) at an over-flooding moth ratio of 10T:1U (treated to untreated). Their efficacy in stopping E. saccharina incursions and suppressing wild populations was measured prior to testing under true season-long and area-wide conditions. Results from the current study demonstrated that releasing partially irradiated (200 Gy) adult male moths at the abovementioned release rate significantly reduced sugarcane stalk damage, and also reduced the number of fertile progeny from F1 to succeeding generations in a stable E. saccharina population initiated in a cage-house. There were more damaged internodes per stalk in the control than in the sugarcane receiving regular releases of partially sterile male moths. Overall, there were significantly more undamaged stalks in the treated sugarcane than the untreated control. Furthermore, there were significantly more larvae per stalk retrieved from the control than from the treated sugarcane, suggesting that the sustained release of steriles was efficacious in reducing emergence of fertile larvae in the succeeding generations. The results of this study indicate that there is considerable scope for the Sterile Insect Technique (SIT) against this damaging pest of sugarcane.
Statistical Impossibility Results for Oblivious Transfer Reductions

Due to its universality oblivious transfer (OT) is a primitive of great importance in secure multi-party computation. OT is impossible to implement from scratch in an unconditionally secure way, but there are many reductions of OT to other variants of OT, as well as other primitives such as noisy channels. It is important to know how efficient such unconditionally secure reductions can be in principle, i.e., how many instances of a given primitive are at least needed to implement OT. For perfect (error-free) implementations good lower bounds are known, e.g. the bounds by Beaver (STOC ’96) or by Dodis and Micali (EUROCRYPT ’99). But since in practice one is usually willing to tolerate a small probability of error and since these statistical reductions can be much more efficient, the known bounds have only limited application. In this work we provide lower bounds on the efficiency of 1-out-of-n OT and Rabin-OT reductions to distributed randomness in the statistical case. From these results we derive bounds on reductions to different variants of OT that generalize known bounds to the statistical case. Our bounds hold in particular for transformations between a finite number of primitives and for any error.
Residential electrical demand forecasting in very small scale: An evaluation of forecasting methods

Applications such as generator scheduling, household smart device scheduling, transmission line overload management and microgrid islanding autonomy all play key roles in the smart grid ecosystem. Management of these applications could benefit from short-term load prediction, which has been successfully achieved on large-scale systems such as national grids. However, the scale of the data for analysis is much smaller, similar to the load of a single transformer, making prediction difficult. This paper examines several prediction approaches for day and week ahead electrical load of a community of houses that are supplied by a common residential transformer, in particular: artificial neural networks; fuzzy logic; auto-regression; auto-regressive moving average; auto-regressive integrated moving average; and wavelet neural networks. In our evaluation, the methods use pre-recorded electrical load data with added weather information. Data is recorded from a smart-meter trial that took place during 2009-2010 in Ireland, which registered individual household consumption for 17 months. Two different scenarios are investigated, one with 90 houses, and another with 230 houses. Results for the two scenarios are compared and the performances of the evaluated prediction methods are discussed.
Some Regularity Results for the Pseudospectral Abscissa and Pseudospectral Radius of a Matrix

The $\varepsilon$-pseudospectral abscissa $\alpha_\varepsilon$ and radius $\rho_\varepsilon$ of an $n\times n$ matrix are, respectively, the maximal real part and the maximal modulus of points in its $\varepsilon$-pseudospectrum, defined using the spectral norm. It was proved in [A.S. Lewis and C.H. J. Pang, SIAM J. Optim. , 19 (2008), pp. 1048–1072] that for fixed $\varepsilon>0$, $\alpha_\varepsilon$ and $\rho_\varepsilon$ are Lipschitz continuous at a matrix A except when $\alpha_\varepsilon$ and $\rho_\varepsilon$ are attained at a critical point of the norm of the resolvent (in the nonsmooth sense), and it was conjectured that the points where $\alpha_\varepsilon$ and $\rho_\varepsilon$ are attained are not resolvent-critical. We prove this conjecture, which leads to the new result that $\alpha_\varepsilon$ and $\rho_\varepsilon$ are Lipschitz continuous, and also establishes the Aubin property with respect to both $\varepsilon$ and A of the $\varepsilon$-pseudospectrum for the points $z \in {\mathbb C.
Induction of Adenosine Deaminase and 5′ Nucleotidase Activity in Cultured Human Blood Monocytes and Monocytic Leukemia (THP‐1) Cells by Differentiating Agents

The in vitro effect of short‐term culture as well as the effect of retinol (ROH), retinoic acid (RA), muramyl dipeptide ([Abu']MDP), lipopolysaccharide (LPS), and gamma interferon (IFN‐γ) on the induction of the purine metabolic enzymes, adenosine deaminase (ADA), purine nucleoside phosphorylase (PNP), and 5′nucleotidase (5NT) in human peripheral blood monocytes (HPBM) was examined. HPBM isolated by centrifugal elutriation were cultured for up to 96 h. Following an initial time lag of 24 h, mean ADA activity from seven separate experiments as measured in nmoles/106 cells/h increased from a baseline of 31.3 ± 9.3 to 57.8 ± 16.4 (P < 0.005) at 72 h and to 72 ± 21.5 (P < .025) by 96 h. 5NT activity increased from a baseline of 2.2 ± 0.9 to a maximum of 44 ± 10.1 by 72 h and then declined to 29 ± 18 (P < 0.005) by 96 h, while no significant change in PNP activity was observed. HPBM incubated for 3 d with optimal concentrations of LPS, RA, and IFN‐γ had increases in ADA and 5NT activity ranging from three‐ to 10‐fold compared to HPBM cultured in media alone, whereas no effect was observed with ROH and [Abu']MDP. RA, but not ROH, significantly enhanced ADA activity in a monocytic leukemia cell (THP‐1) line. Addition of RA or the tumor promoter, phorbol 12‐myristic 13‐acetate (PMA), to HPBM or THP‐1 cells resulted in significant increases in 5NT activity with opposite effects on ADA activity. These findings suggest that the biological mechanisms associated with differentiation in normal and malignant monocytes seem to be related and that the sequence and degree to which the various differentiation agents induce the enzyme elevations are also related to the mechanisms of activation/differentiation.
Orbital eccentricity as a probe of thick disc formation scenarios

We study the orbital properties of stars in four (published) simulations of thick discs formed by (i) accretion from disrupted satellites, (ii) heating of a pre-existing thin disc by a minor merger, (iii) radial migration and (iv) gas-rich mergers. We find that the distribution of orbital eccentricities is predicted to be different for each model: a prominent peak at low eccentricity is expected for the heating, migration and gas-rich merging scenarios, while the eccentricity distribution is broader and shifted towards higher values for the accretion model. These differences can be traced back to whether the bulk of the stars in each case is formed in situ or is accreted, and is robust to the peculiarities of each model. A simple test based on the eccentricity distribution of nearby thick-disc stars may thus help elucidate the dominant formation mechanism of the Galactic thick disc.
Parental and/or Personal Socioeconomic Circumstances: How to Explain Site-Specific Cancer Mortality Inequalities Among Young Belgian Adults

Both socioeconomic position (SEP) in childhood and adulthood are associated with adult mortality. Yet, the relative importance of childhood socioeconomic (SE) conditions is likely to vary depending on the cause of death. This paper will study: 1) whether SE conditions during both childhood and adulthood are associated with overall and site-specific cancer mortality among Belgian young adults; 2) the relative importance of all indicators of parental and personal SEP in explaining differences in cancer mortality. Data were derived from record linkage between the Belgian censuses of 1991 and 2001 and mortality follow-up data for 2001-2011. Parental educational attainment, parental occupational status, parental housing status, and childhood area deprivation were used as measures of parental SEP, and current education as indicator of personal SEP. SE differences were studied for overall and site-specific cancer mortality by calculating age-standardized mortality rates and mortality rate ratios using Poisson regression. Both low parental and personal SEP are associated with higher all-cancer mortality in young adulthood. Personal education seemed to be the strongest indicator of overall and site-specific cancer mortality in young adulthood, independent of parental SEP. Yet, for women, this was partly due to a health selection effect. In the full models, parental SEP was no longer associated with cancer mortality but deprived living conditions still were. Site-specific inequalities were generally more expressed among women than among men. Studies and policies focussing on SE inequalities in mortality in young adulthood should allow for both childhood and adulthood SE conditions.
