Can Recurrent Neural Networks Learn Nested Recursion?

Context-free grammars (CFG) were one of the first formal tools used to model natural languages, and they remain relevant today as the basis of several frameworks. A key ingredient of CFG is the presence of nested recursion. In this paper, we investigate experimentally the capability of several recurrent neural networks (RNNs) to learn nested recursion. More precisely, we measure an upper bound of their capability to do so, by simplifying the task to learning a generalized Dyck language, namely one composed of matching parentheses of various kinds. To do so, we present the RNNs with a set of random strings having a given maximum nesting depth and test its ability to predict the kind of closing parenthesis when facing deeper nested strings. We report mixed results: when generalizing to deeper nesting levels, the accuracy of standard RNNs is significantly higher than random, but still far from perfect. Additionally, we propose some non-standard stack-based models which can approach perfect accuracy, at the cost of robustness.
Neutral winds in the lower thermosphere at high latitudes from five years of EISCAT data

Neutral wind estimates have been computed from EISCAT CP-1 data of the years 1985-1990 at three different altitude levels 101/102 km, 109/110 km, and 117/120 km. They are discussed in terms of semi-diurnal variations and mean winds as a function of season and altitude. Comparisons with theoretical models as well as with other experimental results from incoherent scatter radars, MF-radars, and meteor radars show a general good agreement. The influence of magnetospheric disturbances on the neutral wind and its fundamental variations is investigated using average Kp-values. A critical discussion of errors and uncertainties in our approach is also included
Impasse of the Angels: Scenes from a Moroccan Space of Memory

In Impasse of the Angels, Stefania Pandolfo takes the critical engagement of anthropology to its limit by presenting the relationship between observer and observed as one of interacting equals and mutually constituting subjects. Narrating, debating, and imagining, real characters take center stage and, through their act of speech, invent a people rather than stand for it. Exploring what it means to be a subject in the historical and poetic imagination of a Moroccan society, Impasse of the Angels listens to dissonant and often idiosyncratic voices elaborate the fractures, wounds, and contradictions of the Maghribi postcolonial present. Passionate and lyric, ironic and tragic, it is a transformative narrative experiment traveling the boundary of ethnography and fiction.
An Empirical Evaluation of Factors Influencing Patients’ Reactions to the Implementation of Health Information Exchanges (HIEs)

ABSTRACT Health Information Exchanges (HIEs) offer the potential to fundamentally transform the healthcare system, yet little is known on what happens if healthcare organizations adopt HIEs but patients refuse to allow their health information to be exchanged electronically among healthcare providers. This work attempts to extend the application of privacy calculus theory in the HIE domain by developing and testing a model centered on the perceived benefits, perceived risks, and their antecedents to predict consumers’ opt-in behavioral intention toward HIEs. We conducted an online survey in the USA using 740 samples. The results demonstrate that the advantages of HIEs compared with the traditional exchange options meaningfully contribute to perceived benefits of HIEs. Moreover, trust in HIE models, the transparency of data exchange, and the degree of control over data access significantly attenuate perceived risks of HIEs. The model proposed by this study can be used as a useful conceptual tool for both researchers and practitioners to examine the complex nature of patients’ reactions to the use of HIEs.
Ocorrência de onicomicose em pacientes atendidos em consultórios dermatológicos da cidade do Rio de

Summary: B ACKGROUND - Infection by dermatophytes affects 40% of the world population and represents 30% of all mycotic cuta-neous infections, onychomycosis being the most frequent disease of the nails, counting for 18 to 40% of all onychopathies.Onychomycosis is caused primarily by dermatophytes, Candida spp . and other non-dermatophyte fungi. Among the etiologic agentsthe most common are dermatophytes and especially Trichophyton rubrum . Nowadays Candida spp . can invade the distal and prox -imal nails. Onychomycosis due to non-dermatophyte fungi has been increasing in prevalence and in view of the clinical similari-ty with onychomycosis caused by dermatophytes, a laboratorial diagnosis is necessary for its differentiation.O BJETIVES - The objective of the present work is to evaluarte the occurrence of onychomycosisin the city of Rio de Janeiro.M ETHODS - Out of 2920 patients attended between January 1998 and December 1999, 1416 presented abnormalities in their nails. R ESULTS - Mycological confirmation of onychomycosis was performed in 565 patients and the estimated prevalence in the city of Riode Janeiro is 19.34%. Women were more affected than men, with a ratio of almost 2:1. The distribution according to etiologicalagent of 224 patients with onychomycosis and who presented positive culture was: dermatophytes 64.7%;
Consumers' intention to use generic‐drug discount programmes

Generic‐drug discount programmes (GDDPs) offer generic drugs at subsidized costs to both insured and uninsured consumers in the USA. Understanding predictors of intention to use GDDPs could help in developing interventions to direct more consumers to take advantage of such programmes. The objective of this study was to identify predictors of intention to use GDDPs using the theory of planned behaviour (TPB).
4×25 GHz uni-traveling carrier photodiode arrays monolithic with InP-based AWG demultiplexers using the selective area growth technique

We use the selective area growth (SAG) technique to monolithically integrate InP-based 4-channel arrayed waveguide gratings (AWGs) with uni-traveling carrier photodiode arrays at the O-band. Two kinds of channel spacing demultiplexers of 20 nm and 800 GHz are adopted for potential 100 Gbps coarse wavelength division multiplexing and local area network wavelength division multiplexing systems, with an evanescent coupling plan to facilitate the SAG technique into device fabrication. The monolithic chips in both channel spacings exhibit uniform bandwidths over 25 GHz and a photodiode responsivity of 0.81 A/W for each channel, in agreement with the simulated quantum efficiency of 80%. Cross talk levels are below −20 dB for both channel spacing chips.
High-dimensional statistical learning and nonparametric modeling

High-dimensional data analysis has become increasingly frequent and important in various fields of sciences, engineering, and humanities, ranging from computational biology and health studies to financial engineering and risk management. This thesis addresses two important problems in high-dimensional data: estimation of network structure (precision matrix) among the variables and variable selection in ultrahigh additive models as well as the Cox’s proportional hazards model. For network estimation in graphical models, we introduce non-concave penalties such as SCAD and the adaptive LASSO penalty to attenuate the bias problem. Simulation experiments and asymptotic theory are used to justify the proposed methods. In the second part, we extend the correlation learning proposed in Fan and Lv (2008) to marginal nonparametric learning in the ultrahigh sparse additive model as well as the Cox’s proportional hazards model. The corresponding iterative versions are also provided to further reduce the false selection rate. Under the nonparametric additive models, it is shown that under some mild technical conditions, the proposed independence screening methods enjoy the sure screening property. The extent to which the dimensionality can be reduced by independence screening is also explicitly quantified. In addition, the thesis proposes a unified family of parametrically-guided nonparametric estimation schemes with theoretical justification and numerical demonstration. This combines the merits of both parametric and nonparametric approaches and enables us to incorporate prior knowledge.
Caracterització de les estructures granulars patològiques presents a l’hipocamp dels ratolins amb senescència accelerada SAMP8

La soca de ratolins amb senescencia accelerada SAMP8 es utilitzada habitualment com a model de senescencia; i el seu us per a l’estudi de la malaltia d’Alzheimer s’ha estes degut a la manifestacio espontania dels seus trets histopatologics distintius. En estudis recents es va identificar la presencia de granuls amiloides a l’hipocamp dels ratolins SAMP8. Aquests clusters de granuls augmenten amb l’edat i s’estenen al llarg de l’hipocamp. A mes a mes, les caracteristiques morfologiques dels granuls amiloides son molt similars als granuls tenyits amb Periodic Acid Schiff (PAS), descrits anteriorment en els SAMP8 i en ratolins envellits d’altres soques. L’objectiu principal d’aquesta tesi ha estat estudiar la composicio, l’origen i el desenvolupament dels granuls que apareixen amb l’edat a l’hipocamp dels ratolins senescents SAMP8 amb la finalitat d’aportar nova informacio sobre la neuropatologia d’aquests ratolins per al seu us com a model de la malaltia d’Alzheimer. En aquest treball s’ha identificat la correspondencia entre els granuls amiloides i els granuls PAS de l’hipocamp d’aquests animals. Aquests granuls son el resultat d’un proces degeneratiu present en els astrocits i que pot afectar tambe zones properes, i estan formats per fragments membranosos provinents de l’acumulacio de restes d’estructures i organuls, com els mitocondris. A mes a mes, s’ha identificat la presencia d’un neo-epitop en el nucli dels granuls que es, almenys parcialment, de naturalesa glucidica. Aquest neo-epitop es reconegut per anticossos IgM contaminants presents en anticossos comercials produits en ascites de ratoli o serum de ratoli i conill. Aquestes IgM contaminants son probablement anticossos naturals, i algunes IgM hemaglutinen de forma positiva i especifica els eritrocits humans de tipus A. La presencia tant del neo-epitop com de les IgMs han estat la causa de falses tincions positives que han generat interpretacions erronies del significat fisiopatologic dels granuls. Es el cas, per exemple, de la presencia de ? -amiloide o la proteina tau en aquestes estructures. Finalment, les lesions cerebrals de pacients associades a malalties neurodegeneratives i a l’envelliment no corresponen als clusters de granuls de l’hipocamp d’aquests ratolins, tot i que seria interessant estudiar la presencia del neo-epitop en aquestes condicions fisiopatologiques.
A real time brain machine interface for hand grasping via signals from higher order cortical areas

Drawing on a wealth of knowledge about cortical movement processing, together with recent advances in signal processing and acquisition technology, the field of brain machine interfaces (BMIs) has the potential to become a viable assistive tool for patients with chronic spinal cord injury, stroke, and other motor debilitating diseases. Here, we present our efforts on development of a neural interface for decoding specific hand grasping postures in macaque monkeys. In contrast to the vast body of the literature, where M1 is used as the major source of motor related neural activity, our approach aims at decoding the neural activity in the anterior intraparietal cortex (AIP) and ventral premotor cortex (F5). These are higher-order motor planning areas, which play a role in sensorimotor integration during movement planning and believed to be holding an abstract representation of hand grasping actions. In this work, we formulated 3 main research questions and treated them subsequently; First, as the major research question of this thesis, we investigated the feasibility of using multi-unit neural activity from AIP and F5 for decoding discrete hand postures in a real-time BMI setting with closed feedback. This approach builds upon the previous studies from our lab and targets conceptual proof of using neural signals from AIP and F5 in a real time setup with a clinical neuroprosthetic device ultimately in mind. Our initial analysis confirmed that real-time recorded signal characteristics have similar tuning properties to cells in previous single-unit recording studies. The maximum average decoding accuracy observed for two grasp types (power and precision grip) and five wrist orientations was 63% (chance level, 10%). Analysis of decoder performance showed that grip type decoding was highly accurate (90.6%), with most errors occurring during orientation classification. Furthermore, we observed significant differences in the contributions of F5 and AIP for grasp decoding, with F5 being better suited for classification of the grip type and AIP
Improving the Preanalytical Process: The Focus on Specimen Quality

Improving the Preanalytical Process: The Focus on Specimen Quality Trends in clinical laboratory practice place more demands on the quality of patient specimens. Advances in analytical performance (i.e., increased automation, reduced sample volume, increased assay sensitivity), as well as efficiency and cost reduction gains (i.e., throughput, test turnaround time) have improved medical practice. These changes, however, have caused an increased incidence of preanalytical errors, dictating the need for higher-quality specimens. The following paper addresses these errors in addition to methodologies for improving the quality of the preanalytical phase. Poboljšanje Preanalitičkog Procesa: Fokusiranje NA Kvalitet Uzorka Trendovi u kliničkoj laboratorijskoj praksi postavljaju više zahteva za kvalitet uzoraka pacijenata. Unapređenje analitičkih karakteristika (npr. povećanje automatizacije, smanjenje zapremine uzorka, povećanje osetljivosti određivanja), kao i efikasnost i smanjenje troškova (npr. prohodnost, vreme obrta testova) unapredilo je medicinsku praksu. Međutim, te promene su izazvale povećanje incidencije preanalitičkih grešaka što nameće potrebu za uzorcima većeg kvaliteta. Sledeći članak govori o tim greškama kao i o metodologijama za poboljšanje kvaliteta preanalitičke faze.
Gathering Moss: A Natural and Cultural History of Mosses

Living at the limits of our ordinary perception, mosses are a common but largely unnoticed element of the natural world. Gathering Moss is a beautifully written mix of science and personal reflection that invites readers to explore and learn from the elegantly simple lives of mosses.Robin Wall Kimmerer's book is not an identification guide, nor is it a scientific treatise. Rather, it is a series of linked personal essays that will lead general readers and scientists alike to an understanding of how mosses live and how their lives are intertwined with the lives of countless other beings, from salmon and hummingbirds to redwoods and rednecks. Kimmerer clearly and artfully explains the biology of mosses, while at the same time reflecting on what these fascinating organisms have to teach us.Drawing on her diverse experiences as a scientist, mother, teacher, and writer of Native American heritage, Kimmerer explains the stories of mosses in scientific terms as well as in the framework of indigenous ways of knowing. In her book, the natural history and cultural relationships of mosses become a powerful metaphor for ways of living in the world.Gathering Moss will appeal to a wide range of readers, from bryologists to those interested in natural history and the environment, Native Americans, and contemporary nature and science writing.
The effect of hypocapnia on coronary vascular resistance in the dog.

3. When a map, drawing or chart, etc., was part of the material being photographed the photographer followed a definite method in "sectioning" the material. It is customary to begin photoing at the upper left hand corner of a large sheet and to continue photoing from left to right in equal sections with a small overlap. If necessary, sectioning is continued again — beginning below the first row and continuing on until complete.
Iranian EFL learners' Perception of the Use of L1 to L2 Translation Task in General English Classes

The use of first language in learning a second language has always been a controversial issue in language methodology. While some foreign language teachers may think of translation as a critical means to ensure students’ comprehension and a very significant writing exercise (Atkinson, 1987), other researchers (e.g., Harbord, 1992; Gorsuch, 1998) may totally forbid or discourage the use of the students' native language and translation in the classroom. Despite such controversies, it is not yet known whether Iranian learners have negative or positive beliefs about the use of L1 to L2 translation tasks in their English learning. In doing so, 200 participants were selected through convenience sampling and divided into two groups of pre-and upper intermediate. Two instruments were used to collect the data. Inferential and statistical statistics techniques were used to analyze the data. The results of data analysis indicate that the participants of the study believe that they use translation tasks to learn all language skills. The results also indicated that there was significant difference between pre and upper intermediate language learners' scores on their beliefs about translation and translation use.
Infants-feeding practices and their relationship with socio-economic and health conditions in Lahore, Pakistan

Background: Pakistan, has high infant mortality rate. Among every 1000 live births 0.76% becomes the victim of death due to malnutrition and fatal infections. Therefore, feeding modes and practices may serve as important factors for assessment of an infant's growth and nutritional status. This study was designed to assess the exclusive breast feeding rate, frequency of diseases during breast feeding, status of breast feeding along with weaning, level of education, occupation and socio-economic status of parents. Methods: In the descriptive and cross-sectional study, a total of one hundred (100) infants were included. The sampling technique was non-probability convenience sampling. This study was conducted at vaccination centers and children clinics in different hospitals in city of Lahore -Pakistan. Results: The results showed that 67% of the mothers exclusively breastfed their babies. 64% of the mothers had knowledge of exclusive breast feeding. The practice of breast feeding was found as 81% while artificial feeding was practiced among 19% of the mothers. Majority of the mothers started weaning their babies at the age 4 (31%) and 6 months (32%) whereas 28% mothers started after 6 months. 54% of mothers continued breastfeeding along with weaning. 72% of the mothers were aware of the importance of colostrum. Conclusion: Maternal education and women's employment have been found major determinants for breastfeeding. The result indicates that in Pakistan, mothers receive counseling on breast feeding which is quite satisfactory and feeding practices of infants are found as better in Pakistan.
Dislodgement of a renal stent causing renal infarct during endovascular abdominal aortic aneurysm repair with chimney graft for juxtarenal aortic aneurysm: A rare complication

Chimney grafts (CG) have been used in the repair of juxtarenal aortic aneurysm (JAA) as a pure endovascular approach, which involve the concurrent deployment of an aortic endograft with covered stents in the renal arteries. In the present study, we report a rare but significant complication of chimney grafting in a case of JAA with iliac artery ectasia. During the placement of CG, one of the covered stents was dislodged in a distal branch of the right renal artery, resulting in segmental infarct of the right kidney.
Efficient training strategies for deep neural network language models.

Many works have shown that neural network language models consistently achieve significant improvements in applications like speech recognition and statistical machine translation. However, little research is devoted to explore optimal training strategies. This paper presents an extensive study on the best-practice to train large neural network language models on a corpus of more than 5.5 billion words. We provide solutions to questions like: how to train a neural network on so many examples using the back-propagation algorithm and data selection ? Is careful initialization important ? How to speed-up training ? Can we benefit from deep architectures ? Our best neural network language model can be trained in less than 40 hours on a GPU card and achieves a 25% perplexity reduction. An important finding is that deep architectures systematically achieve better translation quality than shallow ones. We also investigate training of feed-forward architectures on context sizes of more than 30 words. By these means, we aim at achieving an “unlimited history” similar to recurrent architectures.

Efektivitas Promosi Kesehatan menggunakan Metode Ceramah tentang HIV/AIDS terhadap Pengetahuan dan Sikap Remaja di SMK Tritech Informatika dan SMK Namira Tech Nusantara Medan tahun 2016

the problem of HIV/AIDS in teenagers, based on a survey, shows that 57.8% of AIDS cases infect teenagers in the age group of 15-29 years old; this indicates that those who are infected by HIV are still young. Up to March, 2010 there had been 20,564 cases and 54.3% of them infected teenagers. Until the end of June, 2011, there had been 26,483 cases of AIDS in Indonesia. The real number was about 270,001 cases of HIV and AIDS in Indonesia. More than 60% of people infected by HIV are less than 30 years old. Therefore, it is necessary to make an effort to prevent teenagers from being infected by HIV (KPA, 2010). The objective of the research was to analyze the effectiveness of speech method about HIV/AIDS on teenagers’ knowledge and attitude at SMK Tritech Informatika and SMK Namira Tech Nusantara, Medan, in 2013. The type of the research was quasi-experiment with static group comparison design with pretest-posttest. The population was all X grade and XI grade students of SMK Tritech Informatika. The samples consisted of 86 respondents, divided into two groups: 43 students belonged to the treatment group with speech method at SMK Tritech Informatika, and the other 43 students belonged to the control group at SMK Namira Tech Nusantara. The data were gathered by using questionnaires and analyzed by using Paired-Samples T Test and Chi Square test which statistically meant that p 0.05 and attitude in the treatment group from 32.34 to 44.86 with p=0.001, compared with attitude in the control group, from 34.00 to 35.48 with p=0.326 >0.05. The result of Chi Square test showed that communicators had correlation with knowledge p=0.001 and attitude p=0.004 about HIV/AIDS in teenagers at SMK Tritech Informatika, Medan, in 2013. Recommended for the school that makes a counseling program on a regular basis for teenagers using a lecturer or a good communicator, so as to convey the messages and information about HIV and AIDS to students on an ongoing basis.
