Verification, Reproduction and Replication of NLP Experiments: a Case Study on Parsing Universal Dependencies
Venue: UDW
Year: 2020

As in any field of inquiry that depends on experiments, the verifiability of experimental studies is important in computational linguistics. Despite increased attention to verification of empirical results, the practices in the field are unclear. Furthermore, we argue, certain traditions and practices that are seemingly useful for verification may in fact be counterproductive. We demonstrate this through a set of multi lingual experiments on parsing Universal Dependencies treebanks. In particular, we show that emphasis on exact replication leads to practices (some of which are now well established) that hide the variation in experimental results, effectively hindering verifiability with a false sense of certainty. The purpose of the present paper is to highlight the magnitude of the issues resulting from these common practices with the hope of instigating further discussion. Once we, as a community, are convinced about the importance of the problems, the solutions are rather obvious, although not necessarily easy to implement.
Medical Cannabis Use among Adults in the Southeastern United States.
Venue: Cannabis
Year: 2019

To assess the self reported reasons for medical cannabis use within the southeastern United States and compare recreational and medical cannabis users.  This study was a cross sectional survey administered in 2017 through Amazon's Mechanical Turk and enrolled 432 adult, regular cannabis users. Measures included demographics, cannabis use characteristics, and medical reasons for cannabis use.  Under half (47% of respondents endorsed using cannabis for both medical and recreational reasons and 12% reported medical use only. The most commonly cited reasons for medical cannabis use were psychiatric and 60 unique medical conditions were listed. Recreational and medical users were similar on several measures of current use, but did vary in their use history, methods of use, and product knowledge.  Despite state laws and conclusive scientific evidence to support medical cannabis use for certain conditions, cannabis is still used frequently for a range of medical issues. Policy Implications These data may assist healthcare providers in better understanding medical cannabis use in states with tightened restrictions and tailoring information to medical cannabis users about their specific conditions and prioritizing therapeutic options.
Design and Implementation a Real Time Targets Tracking Simulation in ADT Radar
Venue: Journal of Engineering and Applied Sciences
Year: 2019

The Automatic Detection and Track (ADT) radar is one of the most important types of modern radar. This radar rapidly scans a limited angular sector to maintain tracks with a moderate data rate, on more than one target within the coverage of the antenna. It is used for air defense radars, aircraft landing radars and in some airborne intercept radars to hold multiple targets in track. The aim of this research is to study the tracking algorithm used in targets tracking such as tracking filters, tracking gate and data association. Firstly, we will study the basic principles of these algorithms by MATLAB tools, so we can study all advantages and disadvantages of these algorithms, after that we will design a software tools by visual C+ to implementation these algorithms in real time mode, so that, we can improve this algorithm and represent radar work very close to reality. Firstly, in this research, we will use the basic filters like (a b) (a b g) and Kalman filter then in the next experiments we can easily use this simulation to add newest filters and algorithms like Extended Kalman Filter (EKF) Particles Filter (PF) maneuver detector algorithm, Multi Model Interaction (MMI) etc.
[Advanced Pharmaceutical Management Functions in Home Pharmaceutical Care]
Venue: Yakugaku zasshi Journal of the Pharmaceutical Society of Japan
Year: 2020

In 1994, community pharmacists first started patient visiting services under health insurance coverage. There are a wide variety of home care patients for whom pharmacists provide care. They include elderly patients with chronic disease, pediatric home care patients with or without special needs, patients with dementia, cancer patients receiving palliative care, and others. Pharmacies engaging in home pharmaceutical care should establish an adequate system in terms of the following aspects: 1) number of pharmacists; 2) availability of a sterile dispensing room; 3) stock of medical narcotics; and 4) stock of medical supplies. Nevertheless, it is impossible for every pharmacy to provide home pharmaceutical care in the same fashion, since many factors, such as the vision of the pharmacy proprietor, business size, experience and expertise of pharmacists, and regional characteristics vary. A survey of 149 pharmacies authorized to dispense injection drugs in Tokyo clarified the profile of pharmacies specializing in home pharmaceutical care based on the number of patients served, number of patients receiving at home end of life care, amount of medical narcotics in stock, etc. The results revealed that specialized pharmacies were required by home care patients who were highly dependent on medical treatment. In the future, as the number of home care patients with high medical treatment dependence is expected to continue rising, an evaluation of pharmacies meeting the needs of these patients should be undertaken from the viewpoint of advanced pharmaceutical management functions.
Therapeutic effect of pre operative tirofiban on patients with acute ischemic stroke with mechanical thrombectomy within 6 24 hours
Venue: Interventional neuroradiology journal of peritherapeutic neuroradiology, surgical procedures and related neurosciences
Year: 2019

The objective of this study was to investigate and discuss the therapeutic effect of pre operative tirofiban on patients with acute ischemic stroke (AIS) with mechanical thrombectomy (MT) within 6 24 h.  We retrospectively queried our AIS database from January to November 2018, and selected 99 patients with AIS within 6 24 h and evidence of proximal large vessel occlusion who were suitable for MT. They were divided into two groups, group A (with tirofiban, n 56) and group B (without tirofiban, n 43) according to whether they were intravenously infused with tirofiban before MT. The baseline characteristics and outcomes of patients were subjected to statistical analysis, including age, gender and risk factors, occlusion site, the time from onset to door, time of door to puncture, baseline National Institutes of Health Stroke Scale (NIHSS) pre operative Alberta stroke programme early CT (ASPECT) score, angioplasty/stenting, modified Rankin Scale score 0 2 at 3 months, symptomatic haemorrhage and mortality, the time of door to recanalization, endovascular procedure time, 7 day (7d) NIHSS score, and a modified treatment in cerebral infarction (m TICI) grade of 2b or 3. All of the thrombi were analysed by histopathology.  The differences in the time of door to recanalization, endovascular procedure time, 7d NIHSS score and the m TICI were significantly different between groups (P 0.05) The other agents were not significantly different between groups (P 0.05 each) Histopathological analysis showed that all thrombi contained different amounts of platelets, fibrinogen, Haemamoebas and red blood cells.  The use of tirofiban before MT can shorten the procedure time and improve the recanalization rate of occluded vessels in AIS patients.
Establishing trustworthiness and authenticity in qualitative pharmacy research.
Venue: Research in social administrative pharmacy RSAP
Year: 2020

Spurred by the value it can add, the use of qualitative research methods has been steadily growing by social pharmacy researchers around the globe, either separately or as part of mixed methods research projects. Given this increase, it is important to provide guidance to assist researchers in ensuring quality when employing such methods. This commentary addresses both theoretical fundamentals as well as practical aspects of establishing quality in qualitative social pharmacy research. More specifically, it provides an explanation of each of the criteria of trustworthiness proposed by Lincoln and Guba (credibility, transferability, dependability and confirmability) and different techniques used in establishing them. It also provides a brief overview of authenticity, a more recent and less widely used set of criteria that involve demonstrating fairness, ontological authenticity, educative authenticity, catalytic authenticity, and tactical authenticity. For each of these terms, the commentary provides a definition, how it applies to social pharmacy research, and guidance on when and how to use them. These are accompanied by examples from the pharmacy literature where the criteria have been used. The commentary ends by providing a summary of competing viewpoints of establishing quality in the published literature while inviting the reader to reflect on how the presented criteria would apply to different qualitative research projects.

In this paper, we explore student dropout behavior in Massive Open Online Courses(MOOC) We use as a case study a recent Coursera class from which we develop a survival model that allows us to measure the influence of factors extracted from that data on student dropout rate. Specifically we explore factors related to student behavior and social positioning within discussion forums using standard social network analytic techniques. The analysis reveals several significant predictors of dropout.
The matrix eigenvalue problem GR and Krylov subspace methods
Year: 2007

This book presents the first in depth, complete, and unified theoretical discussion of the two most important classes of algorithms for solving matrix eigenvalue problems: QR like algorithms for dense problems and Krylov subspace methods for sparse problems. The author discusses the theory of the generic GR algorithm, including special cases (for example, QR, SR, HR) and the development of Krylov subspace methods. Also addressed are a generic Krylov process and the Arnoldi and various Lanczos algorithms, which are obtained as special cases. The chapter on product eigenvalue problems provides further unification, showing that the generalized eigenvalue problem, the singular value decomposition problem, and other product eigenvalue problems can all be viewed as standard eigenvalue problems. The author provides theoretical and computational exercises in which the student is guided, step by step, to the results. Some of the exercises refer to a collection of MATLAB programs compiled by the author that are available on a Web site that supplements the book.  Readers of this book are expected to be familiar with the basic ideas of linear algebra and to have had some experience with matrix computations. This book is intended for graduate students in numerical linear algebra. It will also be useful as a reference for researchers in the area and for users of eigenvalue codes who seek a better understanding of the methods they are using.

Evanescent field interaction with Fe3O4 nano particle for passively Q switched thulium doped fiber laser at 1.94 mm
Venue: Optics Laser Technology
Year: 2019

We experimentally demonstrate the use of Fe3O4 based saturable absorber (SA) to generate self starting, passively Q switched pulses at 1943 nm. The Fe3O4 particles were characterized with scanning electron microscopy with energy dispersive spectroscopy. The size distribution of Fe3O4 particles was varied from ~150 nm to 980 nm. The proposed SA was fabricated with combination of a side polished fiber and the Fe3O4 particle by using evanescent field interaction between the side polished fiber and the Fe3O4 particle. The insertion loss and polarization dependent loss of the proposed SA were measured as ~4 dB and 0.3 dB, respectively at a wavelength of 1930 nm. The stable passively Q switched pulses were readily generated from thulium doped fiber laser incorporating the proposed SA at 1943 nm. The pulse width was changed from ~8.1 ms to ~880 ns while the repetition rate was changed from ~61 kHz to ~87 kHz. The tuning capability of both pulse width and repetition rate was also shown according to pump power.
Practical and Efficient System Identification of Precision Gantry Systems
Year: 2018

This research develops a procedure to eciently measure the multi input multi output frequency response of precision gantry systems. A precision gantry considered here is dened as two axes moving a bridge in tandem with a third axis mounted to the bridge. An e cient method of measuring the frequency response will decrease the total time required for designing a controller, and higher volumes of gantries can be processed in a set amount of time. Sequential, random phase multisine signals are chosen as an excitation signal for the system identication. A model guided methodology based on system parameters determines how many locations at which the frequency response should be measured, as the response varies with axis location. Guidelines are developed and used to determine that the frequency response of the gantry base and workpoint can be measured using accelerometers in order to provide information about system behavior. The frequency response data is processed using multi input multi output techniques to provide a meaningful, straightforward presentation. The procedure is then structured into an automated program such that minimal user input is necessary. The result is an automated process that can measure and present the multi input multi output frequency response in a deterministic and repeatable manner. The automated procedure is also tested and validated on a sample of industrial gantries.
A Parallel Corpus of Music and Lyrics Annotated with Emotions
Venue: LREC
Year: 2012

In this paper, we introduce a novel parallel corpus of music and lyrics, annotated with emotions at line level. We first describe the corpus, consisting of 100 popular songs, each of them including a music component, provided in the MIDI format, as well as a lyrics component, made available as raw text. We then describe our work on enhancing this corpus with emotion annotations using crowdsourcing. We also present some initial experiments on emotion classification using the music and the lyrics representations of the songs, which lead to encouraging results, thus demonstrating the promise of using joint music lyric models for song processing.
Cardiac Pacemakers: Function, Troubleshooting, and Management: Part 1 of a 2 Part Series.
Venue: Journal of the American College of Cardiology
Year: 2017

Advances in cardiac surgery toward the mid 20th century created a need for an artificial means of stimulating the heart muscle. Initially developed as large external devices, technological advances resulted in miniaturization of electronic circuitry and eventually the development of totally implantable devices. These advances continue to date, with the recent introduction of leadless pacemakers. In this first part of a 2 part review, we describe indications, implant related complications, basic function/programming, common pacemaker related issues, and remote monitoring, which are relevant to the practicing cardiologist. We provide an overview of magnetic resonance imaging and perioperative management among patients with cardiac pacemakers.
Structural Racism, Historical Redlining, and Risk of Preterm Birth in New York City, 2013 2017.
Venue: American journal of public health
Year: 2020

To assess if historical redlining, the US government's 1930s racially discriminatory grading of neighborhoods' mortgage credit worthiness, implemented via the federally sponsored Home Owners' Loan Corporation (HOLC) color coded maps, is associated with contemporary risk of preterm birth 37 weeks gestation).Methods. We analyzed 2013 2017 birth certificate data for all singleton births in New York City (n 528 096) linked by maternal residence at time of birth to (1) HOLC grade and (2) current census tract social characteristics. The proportion of preterm births ranged from 5.0% in grade A "best" green) to 7.3% in grade D "hazardous" red) The odds ratio for HOLC grade D versus A equaled 1.6 and remained significant (1.2; P .05) in multilevel models adjusted for maternal sociodemographic characteristics and current census tract poverty, but was 1.07 (95% confidence interval 0.92, 1.20) after adjustment for current census tract racialized economic segregation. Historical redlining may be a structural determinant of present day risk of preterm birth. Policies for fair housing, economic development, and health equity should consider historical redlining's impacts on present day residential segregation and health outcomes.
Does sociability quality of web based collaborative learning information system influence students' satisfaction and system usage?
Venue: International Journal of Educational Technology in Higher Education
Year: 2020

The use of collaborative learning technologies is a stimulating element of collaborative learning process, where social interaction and collaboration are key factors. This research examines the impact of sociability quality on the usage of web based collaborative learning information system (WBCLIS) and user satisfaction. We propose a theoretical model by integrating the construct of 'sociability quality' in the DeLone and McLean's (Journal of Management Information Systems 19:9 30, 2003) updated information system success model. Proposed theoretical model was empirically validated, in a service learning course with undergraduate students, where data was collected using an online questionnaire and evaluated through partial least square, structural equation modelling (PLS SEM) statistical approach. Results suggest that, sociability quality has a direct positive impact on the system use and overall user satisfaction, along with a strong indirect impact on the net benefits of the WBCLIS. Findings also confirmed that, system use and user satisfaction are strong predictors of the net benefits. These results about sociability quality, contribute significantly in the domain of IS success literature, by identifying a novel and critical IS success dimension. Further, theoretical contribution in the context of sociability quality for IS success, and practical implications entailing the use of WBCLIS in the domain of service learning are also discussed.
Comparison of Empirical and Analytical Physical Assessment Approaches for Stream Restoration: A Case Study on Abrams Creek, Great Smoky Mountains National Park, Tennessee
Year: 2008

A physical assessment approach referred to as natural channel design (NCD) is commonly used today by stream restoration practitioners, which requires an empiricalbased comparison between study and reference reaches. Use of available analytical tools, or models, into pre design physical assessments is not widely applied, an approach that does not require a reference condition. As a case study, a comparison of empirical and analytical approaches was conducted on Abrams Creek, located in the Great Smoky Mountains National Park (GRSM) Tennessee. Historically, the Abrams Creek valley was used for subsistence agriculture beginning in the 19 century, and cattle grazing more recently between the 1930's and 1960's. Several tributaries and a few mainstem sections were channelized for agricultural purposes. GRSM resource managers requested that a channel stability assessment be conducted to evaluate whether restoration was needed because a consulting group was promoting a project on Abrams Creek in order to obtain mitigation credits. This study provided an opportunity to compare geomorphic data input/outputs used in NCD and analytical approaches. The NCD approach utilized stream classification and various geomorphic channel attributes at "bankfull" for a departure type analysis. The analytical approach utilized HEC RAS and CONCEPTS models. Supporting these approaches, assessment of channel condition also included: aerial photo interpretation, rapid geomorphic assessments for stability indices, and longitudinal profile knickpoint analysis. Some of the findings included: 1) bankfull flow was greatly overestimated by the empirical approach, whereas HEC RAS with a hydrological analysis provided a more reasonable estimate, 2) a departure analysis found that C4 study and reference reaches were similar for most geomorphic attributes, except for channel slope and bank material, which made restoration needs difficult to discern, and 3) CONCEPTS provided useful information on bed aggradation/degradation and bank failure rates, whereas the NCD approach could not. In addition, similarities and differences of data input needs, and where professional judgment influences assessment outcomes were identified to better understand uncertainties associated with outcomes for both assessment approaches.
Managing industrial operations by lean thinking using value stream mapping and six sigma in manufacturing unit
Venue: Management Decision
Year: 2019

The purpose of this paper is to cover the significance of lean thinking using value stream mapping and six sigma methodology in managing industrial operations.  Lean manufacturing is an efficient approach for identifying and eliminating waste through a continuous improvement via flow of the product/service at the pull of customer in chase of exactness. This study has been carried out in a manufacturing unit of Northern India that was suffering from high production lead time and work in progress (WIP) inventory.  The current state and future state maps for the critical product have been prepared. On comparison of both current and future state maps, it was observed that lead time has been reduced by 14.88 percent, processing time by 14.71 percent and wastage of material movement by 37.97 percent. As proposed in model, the WIP inventories have been reduced by 17.76 percent and workforce by 17.64 percent. Further it would lead to the profit of Rs161,800 per annum. Six sigma projects have been carried out to reduce rejections of the critical product P 19 under study. The total length of the product was undersize of the critical product. Root cause analysis technique has been used through strategic DMAIC implementation. Results of investigation demonstrated net savings of rupees 145,560 annually.  The paper demonstrates the practical application of lean thinking, showing how it can bring real breakthroughs in saving cost in the manufacturing industry.
