Baseline Extraction Methods of Keyphrases from Scientific Articles

Many academic journals and conferences require that each paper will include a list of keyphrases. These keyphrases provide general information about the contents and the topics of the articles. Keyphrases may save precious time for tasks such as filtering, summarization and categorization. In this paper, we investigate automatic extraction and learning of keyphrases from scientific articles written in English. Firstly, we introduce several base-line extraction methods. Then, we integrate them using different machine learning methods. Results achieved on a collection of 161 scientific articles in different domains are comparable to the state of art.
Real haptics and its applications

Real haptics has been an unsolved problem since its beginning in the 1940s. After much R&D, including the early works in the United States and other countries, bilateral control designed in the acceleration space is a solution for this issue. The quality of touch and tactile sensation is heavily dependent on the transparency between the master side and the slave side. Robust motion control, which is equivalent to acceleration control, gives high transparency. Real haptics is now a key concept in 21st century where the quality of life should be the basis of our society. Various examples are also given. © 2017 Institute of Electrical Engineers of Japan.

Cloning , Expression , and Characterization of the icd Gene in the immI Operon of Bacteriophage P 1

The immI operon of P1 contains the genes c4, ied (formerly called orf), and ant which are constitutively transcribed in that order from a single promoter, PSib. C4 is an antisense RNA which is processed from the precursor transcript. C4 RNA acts as a translational repressor oficd, thereby also inhibiting antirepressor (ant) synthesis. We have cloned the icd and the overlapping icd and ant genes. We show, by means of plasmid deletion analysis, that icd is translationally coupled to ant. An internal in-frame deletion of icd making up 65% of the codons still allows antirepressor synthesis at a reduced rate, indicating that a functionally active icd gene product is dispensable for ant expression. We identify the product of the icd gene as a 7.3-kDa protein which interferes with cell division. The results suggest that constitutive expression oficd, in the absence of a functionally active antirepressor, prevents P1 lysogen formation because of its detrimental effect on the host cell.
360-Degree Video Streaming and Its Subjective Quality

Traditional challenges for end-to-end streaming services are harder when considering 360° video content. One of these challenges relates to the lack of standardized methodologies for subjective 360° video quality assessment, especially for streaming services. This paper presents a methodology for 360° video streaming services, which inherits a lot from the existing International Telecommunications Union standards for subjective quality evaluation of 2D/3D video but also incorporates omnidirectionality. A new metric called similarity ring metric (SRM) is introduced. It measures the degree of similarity in watching patterns of a single subject or between different subjects for several subjective assessment tests. This metric enables a rejection criteria for test results. This paper also presents visual fatigue results for a subjective quality experiment.
Yin-Yang 1, a player regulated systematic inflammatory involved in cognitive impairment of depression

Growing number of clinical and preclinical studies suggest that alterations in peripheral and brain immunal system and followed inflammation are associated with the pathophysiology of depression, also leading to the changes in local glucose metabolism in the brain. Here, we identified Yin-yang 1 (YY1), a transcription factor that has been reported to be closely associated with central and peripheral inflammation. The levels of YY1 and IL-1{beta} were significantly increased in blood samples from depressed individuals, and significantly decreased after treatment with Vortioxetine. Meanwhile, it was found that the level of YY1 in plasma was negatively correlated with visual learning reasoning and problem solving in MDD patients, and positively correlated with the level of IL-1{beta} in plasma. CUMS animals showed depressive-like behavior. Compared with the control group, MicroPET analysis showed that the decrease of glucose metabolism in the hippocampus, entorhinal cortex, amygdala, striatum and mPFC was reversed after treatment. After treatment, these changes were reversed. In conclusion, Our study suggested that YY1- NF-{kappa}B -IL-1{beta} inflammatory pathway may play an essential part on both mood changes and cognitive impairment in depression, and may be associated with changes in glucose metabolism in the emotion regulation and cognition related brain regions. These findings provide new evidence for the inflammatory mechanisms of depression.
Demographic and clinical characteristics of pediatric COVID-19 in Arkansas: March–December 2020

The COVID-19 pandemic reached the United States in early 2020 and spread rapidly across the country. This retrospective study describes the demographic and clinical characteristics of 308 children presenting to an Arkansas Childrens emergency department or admitted to an Arkansas Childrens hospital with COVID-19 in the first ten months of the COVID-19 pandemic, prior to the emergence of clinically significant variants and available vaccinations. Adolescents aged 13 and older represented the largest proportion of this population. The most common presenting symptoms were fever, gastrointestinal symptoms, and upper respiratory symptoms. Patients with multisystem inflammatory syndrome in children (MIS-C) had a longer length of stay than patients with acute COVID-19. Children from urban zip codes had lower odds of admission but were more likely to be readmitted after discharge. Nearly twenty percent of the study population incidentally tested positive for COVID-19. Despite lower mortality in children with COVID than in adults, morbidity and resource utilization are significant. With many Arkansas children living in rural areas and therefore far from pediatric hospitals, community hospitals should be prepared to evaluate children presenting with COVID-19 and to determine which children warrant transport to pediatric-specific facilities.
The Extent and Regulation of Lateral Gene Transfer in Natural Microbial Ecosystems

The importance of horizontal gene transfer (HGT) in bacterial evolution is evident from the retrospective analyses of bacterial genomes, which suggest that a substantial part of bacterial genomes is of foreign origin. Another line of evidence that supports the possibility of rapid adaptation of bacteria through lateral gene exchange is the history of antibiotic use by humans. Within a very brief period of the ‘antibiotic era’ many bacterial pathogens were able to acquire the mechanisms allowing them to withstand the selective pressure of antibiotics. And, finally, the field and microcosm studies allowed monitoring HGT events in situ. In this chapter, a brief overview of the milestones of mobile genetic elements (MGEs) research is given, followed by discussion of the conceptual framework development. Then the occurrence and diversity of MGEs as well as the frequencies of HGT in terrestrial, aquatic, intestinal and biofilm communities are described. The role of environmental factors that may affect MGE-mediated HGT in these ecosystems is also discussed. Introduction The first horizontal gene transfer experiments were performed by Griffith (1928), who ‘transformed’ rough, avirulent live pneumococci into smooth, virulent pneumococci by adding factors from dead, smooth and virulent pneumococci. The word ‘transformation’ at his time had no genetic connotation in the sense we would perceive it today; it was a ‘transformation’ of the pneumococcal phenotype. The nature of the transforming factor remained unknown until the 1940s, when it was recognized as DNA (Avery et al., 1944) and, since then, the term ‘transformation’ acquired a genetic context. The subsequent discovery of bacteriophages (reviewed in Duckworth, 1976) and plasmids (Lederberg, 1952) has laid the foundation for the development of contemporary molecular biology, which has contributed enormously to many fields of biology, medicine, and biotechnology. The understanding of the fundamentals of the structure-and-function of mobile genetic elements as well as the enzymes of DNA metabolism allowed humans to adapt these mechanisms to serve their own needs. In the form of genetic engineering technology, these mechanisms are actively employed in a number of applications in science, biotechnology, and everyday life. In a parallel development, the discovery and application of antibiotics beginning from the early 1940s has revolutionized the branch of clinical microbiology aimed at control and treatment of infectious diseases. Indeed, antibiotics are one of the most successful forms of chemotherapy known in medicine. Infectious diseases, which were the leading causes
Towards Hybrid

Querying over cached indexes of Linked Data often suﬀers from stale or missing results due to infrequent updates and partial coverage of sources. Conversely, live decentralised approaches oﬀer fresh results directly from the Web, but exhibit slow response times due to accessing numerous remote sources at runtime. We thus propose a hybrid query approach that improves upon both paradigms, oﬀering fresher results from a broader range of sources than Linked Data caches while oﬀering faster results than live querying. Our hybrid query engine takes a cached and live query engine as black boxes, where a hybrid query planner splits an input query and delegates the appropriate sub-queries to each interface. In this paper, we discuss query planning alternatives and their main strengths and weaknesses. We also present coherence measures to quantify the coverage and freshness for cached indexes of Linked Data, and show how these measures can be used for hybrid query planning to optimise the trade-oﬀ between fresh results and fast runtimes.
COMPETITIVE STRATEGIES OF INDIGENOUS CONSTRUCTION FIRMS

The Nigerian construction market is one of the most vibrant and largest in Africa. However, indigenous construction firms (ICFs) in Nigeria struggle to survive in a harsh business environment characterized by intense competition and relatively low profit margin. Hence, the aim of this study was to explore the competitive strategies adopted by ICFs in order to improve their competitiveness in spite of stiff competition. The study adopted a cross sectional survey research approach with the use of questionnaires. Seventy two (72) well-structured copies of the questionnaire were distributed to ICFs in Lagos and Abuja, Nigeria based on convenient sampling technique. Data obtained was analyzed by means of descriptive statistics and Spear man’s rank correlation. The findings of the study showed quality in constructed facilities as the most significant competitive strategy of ICFs. The study also indicated a strong and positive correlation between the competitive strategies of quality, schedule and cost. Since tradeoffs in any of these three (quality, schedule and cost) basic project performance criteria can have a devastating impact on project performance, the study concludes that ICFs adopt innovative and inclusive competitive strategies that focus on quality while attempting to achieve on-schedule performance and cost reduction in construction operations.
Explanations of Recommendations Considering Human Factors in Recommender Systems

— Traditional evaluation metrics based on statistical formulas employed to assess the performance of a recommender system are now considered to be inadequate when utilized solely. New metrics considering the quality of user-system interaction alongside with traditional ones have been proposed in evaluation process in order to arrive at more adequate results. Generating explanations for recommendations is a research topic that has emerged as a way to evaluate the system with respect to various criteria considering users’ opinions and feelings. This paper presents the state-of-the-art with respect to the explanation of a recommendation.
Effect of combined carbohydrate-protein ingestion on markers of recovery following simulated rugby union match-play.

This study investigated the effect of ingesting carbohydrate alone or with protein, on functional and metabolic markers of recovery from a rugby union-specific shuttle running protocol. On three occasions, at least one week apart in a counterbalanced order, nine experienced male rugby union forwards ingested placebo, carbohydrate (1.2 g∙kg body mass∙hr -1 ) or carbohydrate with protein (0.4 g∙kg body mass∙hr -1 ) before, during and after a rugby union-specific protocol. Markers of muscle damage (creatine kinase, pre, 258 ± 171 vs 24 hours post, 574 ± 285 U·l -1 ; myoglobin, pre, 50 ± 18 vs immediately post, 210 ± 84 nmol.l -1 , P<0.05) and muscle soreness (1, 2 and 3 [maximum soreness = 8] for pre-, immediately post- and 24 hours post-exercise, respectively) increased. Leg strength and repeated 6s cycle sprint mean power were slightly reduced post-exercise (93 and 95% of pre-exercise, respectively, P<0.05), but were almost fully recovered after 24 hours (97 and 99% of pre-exercise, respectively). There were no differences between trials for any measure. These results indicate that in experienced rugby players, the small degree of muscle damage and reduction in function induced by the exercise protocol were not attenuated by the ingestion of carbohydrate and protein.

Correction of the Unobtrusive ECG Using System Identification

Unobtrusively acquired electrocardiograms (ECG) could substantially improve the comfort of patients. However, such ECGs are not used in clinical practice because (among other reasons) signal deformations impede correct diagnosis of the ECG. Here, methods are proposed for correction of the unobtrusive ECG, based on system identification. Knowing the reference ECG, models were developed to correct the unobtrusively acquired ECG. A finite impulse response (FIR) model, a state space model and an autoregressive model were developed. The models were trained and evaluated on the Goldberger leads recorded from an ECG T-shirt with dry electrodes, and from a gold standard ECG. It was found that the FIR model corrects the unobtrusive ECG with good agreement ( ρ aVR = 0.84 ± 0.10, ρ aVL = 0.65 ± 0.24, ρ aVF = 0.88 ± 0.04), while the other models do not yield significant improvements, or become unstable. The R-peaks were also accurately corrected by the FIR model ( MSE aVR = 0.10 ± 0.10, MSE aVL = 0.14 ± 0.27, MSE aVF = 0.03 ± 0.02). To conclude, the proposed FIR method succeeded in significantly correcting the unobtrusive ECG signal.
Applying the Living Lab Approach for the Design of Public Spaces– A Living Lab Case Study

Living Labs approaches emphasise the importance of real life contexts in public spaces and service provision as an integral design component of the physical space including technological interactions. We report on the findings and outcomes of a Living Lab Project the Waiting Room of the Future Project. This research focuses on a waiting room redesign for Access Health and Community, a partner of the Future Self and Design Living Lab both located in Melbourne, Australia. Waiting rooms are an example of a public space where the physical design is an integral part of the service provision. The emotions of staff and patients have a significant impact on service perception and a direct impact on overall patient satisfaction. Previous studies concerning healthcare waiting rooms provide little emphasis on current and desired emotional responses of stakeholders (e.g. staff, patients, and clinicians). This research focuses on patients’ emotions and communication as an integral component for re-designing patient experiences. We place emphasis on how stakeholders would like to feel when engaging with future technology, spaces and services of a local community health care provider. We illustrate our findings concerning stakeholder experiences using goal models and how they can be translated into an innovative design. In considering the spatial, service, and technology layer in one study at the same time we are able to come up with a waiting room concept that has user needs permeating through all three layers truly addressing the complexity of designing such spaces. Lastly, we offer a variety of co-creative methods that are suitable to enable key stakeholder to communicate their emotions that connect strongly service and technology delivery in healthcare settings.
Who are the salient stakeholders? A perspective from the Chilean mining industry

This paper examines stakeholder salience from a mul ti-stakeholders perspective. Through analysing the data collected through interviews with five sta keholder groups in the Chilean mining industry, the article draws conclusions about how various groups perceive the salience of other stakeholders in relation to corporate social responsibility based o n the attributes of power, legitimacy and urgency. The findings indicate that the stakeholder groups; community, government and unions are perceived as definitive stakeholders. Every stakeholder group identified these groups as the most salient stakeholders. The paper also concludes that stakeho ld r perceptions vary in regard to NGOs and media. These two groups are generally perceived as being latent stakeholders, despite NGOs and the media seeing themselves as expectant stakeholders, increasing their level of salience.

Myogenesis involves the stable commitment of progenitor cells followed by the execution of myogenic differentiation, processes that are coordinated by myogenic regulatory factors, microRNAs and BAF chromatin remodeling complexes. BAF60a, BAF60b and BAF60c are structural subunits of the BAF complex that bind to the core ATPase Brg1 to provide functional specificity. BAF60c is essential for myogenesis; however, the mechanisms regulating the subunit composition of BAF/Brg1 complexes, in particular the incorporation of different BAF60 variants, are not understood. Here we reveal their dynamic expression during embryo myogenesis and uncover the concerted negative regulation of BAF60a and BAF60b by the muscle-specific microRNAs (myomiRs) miR-133 and miR-1/ 206 during somite differentiation. MicroRNA inhibition in chick embryos leads to increased BAF60a or BAF60b levels, a concomitant switch in BAF/Brg1 subunit composition and delayed myogenesis. The phenotypes are mimicked by sustained BAF60a or BAF60b expression and are rescued by morpholino knockdown of BAF60a or BAF60b. This suggests that myomiRs contribute to select BAF60c for incorporation into the Brg1 complex by specifically targeting the alternative variants BAF60a and BAF60b during embryo myogenesis, and reveals that interactions between tissue-specific non-coding RNAs and chromatin remodeling factors confer robustness to mesodermal lineage determination.
CMOS Bulk-Controlled Fully Programmable Neuron for Artificial Neural Networks

ABSTRACT In this paper, the design procedure of a novel neuron is discussed. Starting from the activation function circuit which is based on the modification of regulated cascode structure, a new scheme is presented which can produce the logistic function with high percentage of accuracy. The main advantage of the proposed function generator circuit is its full programmability feature in which its output waveform slope can easily be adjusted by means of the control voltages applied to the bulks of input stage metal oxide semiconductor (MOS) transistors. Also, the output waveform can easily be converted to a step function with the help of bias changes for the input transistors. Following the concepts of the previous work by the authors, the designed activation function has a good compatibility with the employed synapse. Low power and small active-area consumption are the other features of the proposed circuit which qualify it for hardware implementation of neural networks. Post-layout simulation results based on complementary metal-oxide-semiconductor (CMOS) 0.18 µm twin-tub fabrication standard process depict the correct behaviour of the designed circuits and demonstrate 96% accuracy for the proposed activation function structure. The power dissipation of the activation function circuit is 72 µW at the worst case for 1.8 power supply voltage.
