Elevated asthma and indoor environmental exposures among Puerto Rican children of East Harlem.

OBJECTIVE
East Harlem in New York City, a community with a large Puerto Rican population, has among the highest rates of asthma hospitalizations and mortality in the United States, but it is not known if the high rates are related to the ethnic composition, environmental or community factors, or if the higher rates reflect differentials in access to appropriate asthma care. A survey was conducted to: (a) estimate the prevalence of current asthma by ethnicity among school-age children, (b) assess indoor environmental risk factors for childhood asthma, and (c) assess health care utilization and school absences associated with childhood asthma.


DESIGN
A cross-sectional survey of parents of elementary school children, using a self-administered questionnaire with a 12-month recall on asthma symptoms based on the International Study of Asthma and Allergies in Childhood.


SETTING
Two public elementary schools in East Harlem (n = 1615 students 5-12 years of age).


RESULTS
Among the 1319 respondents (response rate 82%), the prevalence for current asthma (doctor or nurse diagnosis at any time plus wheezing in the past 12 months) was 23%. Puerto Rican children had a prevalence of 35%. Puerto Rican children reported both higher symptomatic frequencies and higher rates of physician diagnosis. Living in a home where cockroaches, rats, or mice had been seen in the past month and with a dust-enhancing heating system also was associated with having asthma, regardless of ethnicity. Compared with other children with asthma, Puerto Rican children with asthma were more likely to live in homes where rats or mice had been seen in the past month. Regardless of ethnicity, children with more frequent, more severe asthma symptoms and incomplete asthma action plans were more likely to have visited the emergency department in the past year. Puerto Rican children were more likely to have missed school because of their asthma in the past year.


CONCLUSION
The prevalence of current asthma was significantly higher among Puerto Ricans, who had higher symptomatic frequency and greater diagnosis rates. Although all children with asthma in the East Harlem study appear to be sensitive to selected indoor environmental risk factors, only Puerto Rican children with asthma appear to be sensitive to the presence of rodents in their buildings. However, their higher school absence rate suggests problems with routine asthma management that could be addressed by improved medical management, programs to help parents manage their children's asthma, or school staff assistance with medications.
A Novel High-Throughput Acceleration Engine for Read Alignment

The Smith-Waterman (S-W) algorithm is widely adopted by the state-of-the-art DNA sequence aligners. Existing wave front-based methods ignored the fact that the S-W algorithm is fed with significantly varied-size inputs in modern aligners, in which the S-W algorithm is further optimized by exerting extensive pruning. In this paper, we propose an architecture, tailored for varied input sizes as well as harnessing software pruning strategies, to accelerate S-W. Our implementation demonstrates a 26.4x speedup over a 24-thread Intel Has well Xeon server, and outperforms wave front-based implementations by up to 6x with the same FPGA resource.
1 Topic Segmentation

This chapter discusses the task of topic segmentation: automatically dividing single long recordings or transcripts into shorter, topically coherent segments. First, we look at the task itself, the applications which require it, and some ways to evaluate accuracy. We then explain the most influential approaches – generative and discriminative, supervised and unsupervised – and discuss their application in particular domains.
Towards customizable, application specific mobile trusted modules

Two different security extensions of mobile platforms for hosting Mobile Trusted Module (MTM) functionality have been introduced in recent years: the ARM TrustZone processor extension and Secure Elements. Both approaches can host MTMs which are typically designed as a static and fixed set of functions. However, with the increasing number of supported functions, the complexity of these MTMs is being raised and with it the resource requirements on the hosting security extension. Disembedding MTM functionality and dynamic loading of TPM commands can be a solution to reduce these requirements. In order to address this problem, we propose and analyze two approaches for providing modular, customizable MTM functionality which are based on currently available cell phones' security extensions. We propose two architectures in order to overcome the resource limitations of existing approaches and show how secure and dynamic command loading architectures can be established with the ARM TrustZone extension and Secure Elements.

Artificial Pancreas Device Systems for the Closed-Loop Control of Type 1 Diabetes

BACKGROUND
Closed-loop artificial pancreas device (APD) systems are externally worn medical devices that are being developed to enable people with type 1 diabetes to regulate their blood glucose levels in a more automated way. The innovative concept of this emerging technology is that hands-free, continuous, glycemic control can be achieved by using digital communication technology and advanced computer algorithms.


METHODS
A horizon scanning review of this field was conducted using online sources of intelligence to identify systems in development. The systems were classified into subtypes according to their level of automation, the hormonal and glycemic control approaches used, and their research setting.


RESULTS
Eighteen closed-loop APD systems were identified. All were being tested in clinical trials prior to potential commercialization. Six were being studied in the home setting, 5 in outpatient settings, and 7 in inpatient settings. It is estimated that 2 systems may become commercially available in the EU by the end of 2016, 1 during 2017, and 2 more in 2018.


CONCLUSIONS
There are around 18 closed-loop APD systems progressing through early stages of clinical development. Only a few of these are currently in phase 3 trials and in settings that replicate real life.
Dabigatran etexilate and LMWH for the prevention of venous thromboembolism in 532 patients undergoing hip surgery.

OBJECTIVE
Patients undergoing total hip replacement (THR) are at high risk of venous thromboembolism (VTE) and according to guidelines they should receive pharmacological prophylaxis. We would like to compare the efficacy, adherence and safety of dabigatran and low molecular weight heparins (LMWH) for the prevention of VTE in patients who underwent THR.


PATIENTS AND METHODS
This study enrolled patients undergoing THR treated with dabigatran (110 mg loading dose then 220 mg/day for 34 days) or the LMWH dalteparin (2500 IU, 6-8 hours before surgery then 5000 IU/day for 35 days). The primary endpoint was adherence to treatment.


RESULTS
Of the 532 patients screened and enrolled in the study, 407 (mean age 57.7 ± 12.3 years) completed the study (211 dabigatran, 196 LMWH). Over the 35 days of treatment, adherence was comparable between dabigatran and LMWH: 10.9% and 14.3% of patients receiving dabigatran and LMWH treatment missed > 1 dose of the drug, respectively. There was a lower need for external support in patients who received dabigatran (8.5% vs 58.2%; p < 0.0001) and a lower number of patients receiving dabigatran required support by a professional nurse (1.4% vs 17.3% of patients with LMWH; p < 0.0001). Dabigatran and LMWH were similarly well tolerated; however, fewer patients receiving dabigatran reported bleeding events.


CONCLUSIONS
This study demonstrates that dabigatran is associated with high adherence. A lower need for external support in patients who received dabigatran may provide an added benefit compared with other oral treatments for VTE prophylaxis.
The Santa Clara Strength of Religious Faith Questionnaire: Assessing Faith Engagement in a Brief and Nondenominational Manner

The Santa Clara Strength of Religious Faith Questionnaire is a brief (10-item, or five-item short form version), reliable and valid self report measure assessing strength of religious faith and engagement suitable for use with multiple religious traditions, denominations, and perspectives. It has been used in medical, student, psychiatric, substance abuse, and among general populations nationally and internationally and among multiple cultures and languages. Brief non denominational self report measures of religious and faith engagement that have demonstrated reliability and validity are not common but can have potential for general utility in both clinical and research settings. This article provides an overview of the scale and current research findings regarding its use in both research and clinical practice.
Factored Neural Machine Translation Architectures

In this paper we investigate the potential of the neural machine translation (NMT) when taking into consideration the linguistic aspect of target language. From this standpoint, the NMT approach with attention mechanism [1] is extended in order to produce several linguistically derived outputs. We train our model to simultaneously output the lemma and its corresponding factors (e.g. part-of-speech, gender, number). The word level translation is built with a mapping function using a priori linguistic information. Compared to the standard NMT system, factored architecture increases significantly the vocabulary coverage while decreasing the number of unknown words. With its richer architecture, the Factored NMT approach allows us to implement several training setup that will be discussed in detail along this paper. On the IWSLT’15 English-to-French task, FNMT model outperforms NMT model in terms of BLEU score. A qualitative analysis of the output on a set of test sentences shows the effectiveness of the FNMT model.

A community based epidemiological study of epilepsy in Assiut Governorate/Egypt

BACKGROUND
The aim of the study was to estimate the prevalence of different types of epilepsy and their possible risk factors in the region of the Assiut Governorate/Egypt.


MATERIAL AND METHODS
A community based study with random sampling of 7 districts, involving 6498 inhabitants. Out of this sample, 578 dropped out leaving 3066 males (51.8%) and 2854 females (48.2%). There were 3660 (61.8%) urban residents and 2260 (38.2%) from the rural community. Patients were evaluated using a screening questionnaire for epilepsy, and then referred to the hospital to be re-evaluated by a qualified neurologist and with electroencephalography (EEG) and computed tomography of the brain (CT).


RESULTS
Seventy-five cases were diagnosed with epilepsy giving an overall the crude lifetime prevalence rate (CPR) for epilepsy of 12.67/1000 (95% CI: 9.8-15.54). The active prevalence rate was 9.3/1000 and the incidence rate was 1.5/1000 (95% confidence interval: 0.53-2.51). Fifty-six cases (75%) had idiopathic epilepsy (CPR 9.5/1000). Symptomatic epilepsy was recorded in 19 (25%) cases (CPR 3.2/1000). Generalized seizures were more common (CPR 6.75/1000) than partial seizures (CPR 2.5/1000). The prevalence rate of partial seizures evolving to secondary generalization was 0.84/1000 while simple partial and complex partial seizures had CPR 1.4/1000 and 0.34/1000, respectively. The CPR of mixed seizures was 0.17/1000. Epilepsy was slightly but not significantly more common among males than females (CPR of 14.4 and 10.9 per 1000 population, respectively). The CPR was higher in rural than urban populations (17.7/1000, with 95% CI 12.2-23.18 and 9.56/1000, with 95% CI: 6.39-12.7, respectively) and in the illiterate group than the literate population (12.02/1000 and 9.94/1000, respectively). The highest prevalence rate was recorded in the early and late childhood period (69.78/100,000 and 43.78/100,000, respectively). Prenatal insults and infection represented major causes of symptomatic epilepsy.


CONCLUSIONS
We found a high prevalence rate of epilepsy (comparable with that in other Arabic and European countries) in our community particularly among children and teenagers. Overall the prevalence was higher in the rural than in the urban population. A family history of epilepsy, prenatal insults, and infection represented major risk factors of symptomatic epilepsy.
Analysis of posterior deltoid function one year after surgical restoration of elbow extension.

PURPOSE
The purpose of this study was to measure the extent and timing of elbow extension torque recovery after posterior deltoid-to-triceps tendon transfer.


METHODS
Elbow extension moment was measured in 40 limbs from 23 patients who underwent surgical restoration using the posterior deltoid-to-triceps tendon transfer at times ranging from 8 weeks to 1 year after surgery. For comparison purposes, elbow extension moment also was measured in healthy controls and persons with C7 spinal cord injuries.


RESULTS
Maximum extension moment was 5.89 +/- 0.24 Nm (mean +/- standard error of mean, n = 40), which corresponds to approximately 65% of the predicted posterior deltoid force and provided an adequate moment to oppose gravity. Based on the shape of the moment-joint angle curve and using a biomechanical model, it was predicted that posterior deltoid was inserted at a relatively short muscle length of 123.1 mm and thus operated exclusively on the ascending limb of the length-tension relationship.


CONCLUSIONS
These observations support an evolving model of muscle architecture in which connective tissue septa restrict muscle fiber elongation during surgical tensioning of the tendon transfer. This relatively short length would result in a significant force loss should any of the repair sites slip or stretch during rehabilitation. These data have implications for the reconstruction and rehabilitation of this patient population.
Compact reflective microstrip phase shifter for traveling wave antenna applications

A varactor diode based microstrip phase shifter for 5.8GHz is presented. It is designed for use in microstrip traveling wave antennas where there is a strict limitation on the available space for the phase shifters. To meet all requirements, a reflective type phase shifter is chosen. Such a phase shifter includes a hybrid coupler. A compact branch line coupler is designed to make the phase shifter fit between the radiating elements in the antenna, while maintaining sufficient electrical performance. Phase shifters are designed with different types of stubs connecting the diodes to ground. A phase tuning range of 62deg is measured for a phase shifter with parallel open stubs, and 92deg with shorted stubs. Insertion loss is in both cases less than 0.6dB. A complete five-element array antenna is built and characterized. Measurements show beam scanning angles within plusmn32deg from broadside
ESTIMATES FOR THE FINITE ELEMENT APPROXIMATION OF A SEMILINEAR ELLIPTIC CONTROL PROBLEM WITH STATE CONSTRAINTS AND FINITE DIMENSIONAL CONTROL SPACE

The finite element approximation of optimal control problems for semilinear elliptic partial differential equation is considered, where the control belongs to a finite-dimensional set and state constraints are given in finitely many points of the domain. Under the standard linear independency condition on the active gradients and a strong second-order sufficient optimality condition, optimal error estimates are derived for locally optimal controls.

Robust Face Detection Using the Hausdorff Distance

The localization of human faces in digital images is a fundamental step in the process of face recognition. This paper presents a shape comparison approach to achieve fast, accurate face detection that is robust to changes in illumination and background. The proposed method is edge-based and works on grayscale still images. The Hausdorff distance is used as a similarity measure between a general face model and possible instances of the object within the image. The paper describes an efficient implementation, making this approach suitable for real-time applications. A two-step process that allows both coarse detection and exact localization of faces is presented. Experiments were performed on a large test set base and rated with a new validation measurement. c © In Proc.

Random eye state change detection in real-time using EEG signals

Maximum and minimum computed across channels is used to monitor the Electroencephalogram signals for possible change of the eye state. Upon detection of a possible change, the last two seconds of the signal is passed through Multivariate Empirical Mode Decomposition and relevant features are extracted. The features are then fed into Logistic Regression and Artificial Neural Network classifiers to confirm the eye state change. The proposed algorithm detects the eye state change with 88.2% accuracy in less than two seconds. This provides a valuable improvement in comparison to a recent procedure that takes about 20 minutes to classify new instances with 97.3% accuracy. The introduced algorithm is promising in the real-time eye state classification as increasing the training examples would increase its accuracy. Published by Elsevier Ltd.
The ROSE Source-to-Source Compiler Infrastructure

The development of future software for proposed new computer architectures is expected to make significant demands on compiler technologies. Significant rewriting of applications will be likely to support the use of new hardware features and preserve the current software investment. Existing compilers provide little support for the broad range of research efforts addressing exascale challenges, such as parallelism, locality, resiliency, power efficiency, etc. The economics of how new machines will change an existing code base of software, that is too expensive to manually rewrite, may well drive automated mechanisms to transform existing software to take advantage of future machine features. This approach will lessen the cost and delay of the move to new, and possibly radically different, future architectures. Source-to-source compilers provides a pragmatic vehicle to support research, development, and deployment of novel compiler technologies by compiler experts or even advanced application developers. Within a source-to-source approach the input source code is read by the compiler, an internal representation (IR) is constructed, the IR is the basis of analysis that is used to guide transformations, the transformations occur on the IR, the IR is used to regenerate new source code, which is then compiled by a backend compiler. Our source-to-source compiler, ROSE, is a project to support the requirements of DOE. Work on ROSE has focused on the development of a community based project to define source-to-source compilation for a broad range of languages especially targeted at DOE applications (addressing robustness and large scale codes as required for DOE applications). Novel research areas are most easily supported when they can leverage significant tool chains that interact and use source code while allowing the hardware vendor’s own compiler for low level optimizations. In fact, high level optimization are rarely feasible for existing low level compilers for common languages such as C, C++, and Fortran. ROSE addresses the economics of how compiler research can be moved closer to the audience with significant technical performance problems and for whom the hardware is likely to be changing significantly in the next decade. Within ROSE it is less the goal to solve all problems than to permit domain experts to better solve their own problems. This talk will focus on the design and motivation for ROSE as an open community source-to-source compiler infrastructure to support performance optimization, tools for analysis, verification and software assurance, and general cus[Copyright notice will appear here once ’preprint’ option is removed.] tom analysis and transformations needs directly on software using the languages common within DOE High Performance Computing.
Word Sense and Subjectivity

Subjectivity and meaning are both important properties of language. This paper explores their interaction, and brings empirical evidence in support of the hypotheses that (1) subjectivity is a property that can be associated with word senses, and (2) word sense disambiguation can directly benefit from subjectivity annotations.
Paraphrase Detection Using Recursive Autoencoder

In this paper, we tackle the paraphrase detection task. We present a novel recursive autoencoder architecture that learns representations of phrases in an unsupervised way. Using these representations, we are able to extract features for classification algorithms that allow us to outperform many results from previous works.
