SPECTRO-TEMPORAL ECG ANALYSIS FOR ATRIAL FIBRILLATION DETECTION

This article is concerned with spectro-temporal (i.e., time varying spectrum) analysis of ECG signals for application in atrial fibrillation (AF) detection. We propose a Bayesian spectro-temporal representation of ECG signal using state-space model and Kalman filter. The 2D spectro-temporal data are then classified by a densely connected convolutional networks (DenseNet) into four different classes: AF, non-AF normal rhythms (Normal), non-AF abnormal rhythms (Others), and noisy segments (Noisy). The performance of the proposed algorithm is evaluated and scored with the PhysioNet/Computing in Cardiology (CinC) 2017 dataset. The experiment results shows that the proposed method achieves the overall F1 score of 80.2%, which is in line with the state-of-the-art algorithms. In addition, the proposed spectro-temporal estimation approach outperforms standard time-frequency analysis methods, that is, short-time Fourier transform, continuous wavelet transform, and autoregressive spectral estimation for AF detection.
Comparative study between propofol and propofol-ketamine for induction of anesthesia in dogs Estudo comparativo entre propofol e propofol-cetamina para a indução anestésica em cães

Anesthetic procedures in animals are widely used in hospital for routine surgery. For induction of anesthesia in dogs, propofol has been shown to be the drug of choice. The objectives of this study were the assessment of induction of anesthesia using propofol or propofol-ketamine. Twenty client-owned dogs were randomly assigned to treatment and control groups. All patients were administered acepromazine (0.05 mg kg-1) and fentanyl (5 μg kg-1) for premedication by intramuscular (IM) injection. Dogs in the treatment group were administered ketamine (1 mg kg-1), while dogs in the control group were administered 0.9% saline solution, by intravenous (IV) injection. Induction of anesthesia was done using IV propofol at a rate of 1 mL minute-1. Cardiopulmonary patterns were assessed before application of premedication, 15 minutes after application of premedication and after induction of anesthesia with propofol. Additionally, data regarding tracheal intubation score, presence of adverse effects and dose of propofol necessary for induction of anesthesia were collected. The control group showed significantly more adverse effects and changes in cardiopulmonary patterns when compared to the treatment group. There was a clinically significant reduction in the dose of propofol necessary for induction of anesthesia when associated with ketamine. The association of ketamine for induction of anesthesia in healthy dogs using propofol was able to reduce the dose of the induction agent necessary for tracheal intubation. Moreover, there was a reduction in the occurrence of adverse effects and cardiopulmonary depression, which allowed for a safer procedure for the patients.
You Snooze, You Win: the PhysioNet/Computing in Cardiology Challenge 2018

The PhysioNet/Computing in Cardiology Challenge 2018 focused on the use of various physiological signals (EEG, EOG, EMG, ECG, SaO2) collected during polysomnographic sleep studies to detect sources of arousal (non-apnea) during sleep. A total of 1,983 polysomnographic recordings were made available to the entrants. The arousal labels for 994 of the recordings were made available in a public training set while 989 labels were retained in a hidden test set. Challengers were asked to develop an algorithm that could label the presence of arousals within the hidden test set. The performance metric used to assess entrants was the area under the precision-recall curve. A total of twenty-two independent teams entered the Challenge, deploying a variety of methods from generalized linear models to deep neural networks.
Migrating Learning Management Systems in Higher Education: Faculty Members’ Perceptions of System Usage and Training When Transitioning From Blackboard Vista to Desire2Learn

This study examined a migration from Blackboard Vista to Desire2Learn (D2L) within a multiuniversity system. Faculty members’ perceptions from two of the systems’ colleges were evaluated using a questionnaire based on Davis’ technology acceptance model. Researchers analyzed responses for differences in system usage experience of faculty and in faculty usage of training and support services. Overall, faculty had positive experiences (or experienced few issues) with use of D2L and seemed to use fewer training and support resources during the migration. Although no statistically significant difference was found, recommendations were made to inform future migrations’ success.
Scald Burns in Children. An Analysis with Special Attention to the Roma Ethnic Group in East Slovakia

Objectives: A retrospective analysis of scald burns in children in a region with a significant prevalence of Roma ethnicity living in poor socioeconomic situation. Patients: During 3 year period 273 children were admitted to the Clinic of Burns and Reconstructive Surgery of our hospital; 201 of them were with scald burns accounting for 73.6% of all pediatric burn admissions. More than half (58.7%) of the 201 children with scald burns were of Roma ethnicity. Results: The average BSAB of the children with scald burns was 10.8%; mean length of hospital stay 11.5 days. 58.7% of the children with scald burns was of Roma ethnicity. The non-scald admissions of children had a similar pattern but these children were older and with an even higher prevalence of Roma patients (75%), a slightly lower average BSAB (9.8%) and a significantly longer need of hospital treatment (average 15.7 days). Conclusion: The frequency of scald burn injuries in very young Roma children in our region is very high. Prevention of scald burns is possible only through targeted and well-organized education of this vulnerable population.
The Survival Analysis of the Potential Risk Factors Affecting Lamb Mortality in Deccani Sheep

The lamb mortality is critical component in sheep industry. The present study was carried out to determine the lamb mortality and its associated factors in Deccani sheep using survival analysis. The data records of 2168 lambs reared at ICAR-Network Project on Sheep Improvement, MPKV, Rahuri (India) were obtained from inventory and death registers for the period of January 2005 to December 2015. The survival analysis of lamb mortality using Cox proportional hazard model was undertaken to determine the potential risk factors affecting lamb mortality in the study. All statistical analyses were done using R 3.1. 0 Software. The overall lamb mortality for birth to 1 month age, birth to weaning age and birth to 1 year age was 2.21%, 4.70% and 10.10%, respectively. It was found that lambs with low birth weight had greater risk of mortality than heavier lambs at birth. Male lambs were at higher hazards of mortality than female lambs. Furthermore, higher risk of mortality was observed in rainy season as compared to other seasons. In order to reduce the economic losses due to lamb mortality, implementation of improved farm practices according to seasonal variation, flock structures (pregnant ewes, newly born lambs etc.) is suggested.
Hospital Mergers with Regulated Prices

We study the effects of a hospital merger using a spatial competition framework with semialtruistic hospitals that invest in quality and expend cost-containment effort facing regulated prices. We find that the merging hospitals always reduce quality, whereas non-merging hospitals respond by increasing (reducing) quality if qualities are strategic substitutes (complements). A merger leads to higher average treatment cost efficiency and, if qualities are strategic substitutes, might also increase average quality in the market. If a merger leads to hospital closure, the resulting effect on quality is positive (negative) for all hospitals in the market if qualities are strategic substitutes (complements). Whether qualities are strategic substitutes or complements depends on the degree of altruism, the effectiveness of cost-containment effort, and the degree of cost substitutability between quality and treatment volume.
Comparison of Shear Bond Strength of Silorane and Methacrylate-Based Composites to IPS Empress 2 Ceramic with Various Surface Treatments

Received: 18.10. 2016 Accepted: 27.02. 2017 Abstract Objectives: Treatment of chipped or fractured porcelain with composite resin is considered as an economic treatment for minor fractures in ceramics. The aim of this study was to evaluate the effect of different ceramic surface treatments on bond strength of methacrylate-based and silorane-based composite resin to IPS Empress 2. Methods: Sixty IPS Empress 2 ceramic discs were fabricated and after etching with 9.6% hydrofluoric acid, they were divided into six groups: (1) P90 primer and bonding agent + Filtek P90 composite resin; (2) Single Bond+ Filtek Z250 composite resin; (3) similar to the first group+ silane pretreatment; (4) similar to the second group+ silane pretreatment; (5) silane pretreatment+ Filtek P90 composite resin; (6) silane pretreatment+ Filtek Z250 composite resin. Each specimen was subjected to shear load until fracture occurred. Statistical analysis was performed using one-way ANOVA, Tukey’s test and t-test. Results: Regardless of the type of surface treatment, Z250 composite demonstrated significantly higher shear bond strength than P90 composite (P<0.05). Group 4 showed the highest shear bond strength values with statistically significant difference with other groups while the fifth group showed the least values (P<0.05). Conclusion: Silane coating along with the application of adhesive system and etching in methacrylate-based composite was the most efficient surface treatment in terms of bond strength.
The Relationship between American Sign Language Proficiency and English Academic Development : A Review of the Research

The focus of the review is on the relationship between ASL and English proficiency because this issue is at the centre of current policy debates in Ontario and other educational jurisdictions. For example, there is debate about whether development of ASL fluency might impede, or potentially enhance, English acquisition among Deaf children who have received cochlear implants. There is also discussion regarding the role of ASL-medium instruction in ASL-English bilingual/bicultural programs; for example, will concepts and linguistic skills developed through ASL transfer to English literacy development?
Relative intensity calibration of CDS-GIS detectors on SOHO using a plasma diagnostic technique

The internal intensity calibration of the Coronal Diagnostic Spectrometer (CDS) - Grazing Incidence Spectrometer (GIS) is studied using the Arcetri diagnostic method. A large number of spectral lines observed by the four GIS detectors in solar active and quiet regions is analysed in order to determine the relative intensity calibration curve of the instrument. The plasma diagnostic method developed in Arcetri allows the measurement of the correction factors to the pre-flight CDS - GIS internal intensity calibration curves and of the relative calibration between different detectors. No gross deviations from the pre-flight calibration are found. Also the GIS 3 and GIS 4 second order sensitivites are measured. The problems of fixed patterning, ghosting, anomalous line profiles and widths are also discussed, and a list of lines suitable for further diagnostic studies with GIS is presented.
An investigation of non-target impacts of ryegrass endophytes on nematodes and soil microorganisms.

A pot trial with two sampling times was conducted to compare the non-target effects of Nil endophyte ryegrass with three endophyte/ryegrass combinations, two selected endophytes (AR1 and AR37) and a wild-type, in the same cultivar. Shoot dry weight, soil nematode and microbial abundance and community diversity were assessed at each sample time. Plants infected with wildtype endophyte produced significantly less shoot weight than all other treatments due to slow initial growth. None of the plant-parasitic nematodes were consistently affected by any of the endophyte combinations. There was a significant overall effect of endophyte infection on some bacterial-feeding nematode families which was reflected in the community indices calculated but these were not consistent across sample times. Wildtype endophyte differed significantly from AR1 for one bacterial-feeding nematode family, and differed significantly from all other treatments in composition of Pseudomonas and Actinobacteria communities. Neither total fungal populations nor functional diversity were consistently different amongst treatments. While there were some differences in the microbial and nematode communities at one or other of the sampling times these did not appear to be consistent nor represent a threat to the non-target community as a whole.
Absorption of FD&C Blue No. 1 from enteral feedings: A look back at a patient safety effort with modern relevance

Background: Aspiration of gastric contents is common in the enterally-fed. Tinting enteral feedings with FD&C Blue No. 1 was thought to aid bedside detection of aspiration, yet its safety was never established. After several published reports had shown that dye absorption occurs in this setting and was associated with death, in 2002 we sought more information on clinician recognition of dye absorption from feedings, on patient risk factors, and on outcomes with a goal of sharing data with the US Food and Drug Administration (FDA) in the interest of patient safety. Methods: We completed a survey of 50 dietitians and 50 physicians at 100 hospitals in the United States in 2002-3 who cared for enterally fed patients. We evaluated the frequency of witnessed dye absorption between dietitians and physicians, patient comorbidities, presence of illnesses that increase gut permeability, outcome by level of discoloration, presence of acute renal failure, and analyzed any stored fluid samples. Findings: Dietitians were more likely to encounter dye absorption than physicians (42% versus 20%, p = .017). Available data for 17 cases revealed most patients were critically ill and had conditions associated with increased gut permeability. None of these cases had been reported to the FDA. Blue skin discoloration was significantly associated with death (P < .01). In 2002 we facilitated reporting of all cases to the FDA using the MedWatch system. In 2003 the FDA issued a Public Health Advisory referencing these and other reports. Conclusions: Absorption of FD&C Blue No. 1 from feedings was a serious and underreported complication. This approach highlights the design of a simple patient safety project, the underreporting of sporadic hospital complications, and the utility of surveying hospital dietitians for enteral feeding complications.

Autologous Bone Marrow Mononuclear Cell Transplantation Improves Function in a Case of Becker ’ s Muscular Dystrophy Author ’ s Details :

Becker’s muscular dystrophy (BMD) is a genetic disorder characterized by progressive muscle degeneration and weakness with no definite cure. Cell therapy is emerging as a promising treatment option for BMD. Autologous bone marrow derived mononuclear cells (BMMNCs) transplantation has been shown to be safe and effective in previous preclinical studies. We treated a 21 year old boy suffering from BMD with autologous bone marrow mononuclear cells intrathecal as well as intramuscular transplantation. Pre-therapy clinical assessment showed reduced muscle power in all four limbs and trunk. He was modified independent for all the activities of daily living (ADLs) and scored 102 on Functional Independence Measure (FIM). Musculoskeletal Magnetic Resonance Imaging (MRI-MSK) revealed severe muscular atrophy and fatty replacement in the muscles. Repeat clinical assessment at follow up revealed maintained muscle power along with improvement in some muscles. North Star Ambulatory Assessment score and FIM score was maintained for over nineteen months. Repeat MRI-MSK revealed no increase in fatty infiltration in the muscles indicating halting of the progression of the disease. Thus, this report suggests the role of BMMNCs transplantation in stabilizing the condition of BMD patients. Larger clinical trials with scrupulous methodology may be suggested.
Cognitive Complexity in Counseling and Counselor Education: A Systematic and Critical Review

Cognitive complexity has found a small yet established niche in the counseling and counselor education literature over the last 40 years. This body of research has highlighted how individuals with high cognitive complexity have greater consistency in empathy, show more varied responses to clients, demonstrate greater toleration of ambiguity, and show higher frequencies of unbiased clinical judgements towards clients. This article provides a systematic and critical review of the cognitive complexity literature and discusses future implications of cultivating cognitive complexity in emerging and professional counselors and supervisors.
The early phases of galaxy clusters formation in IR: coupling hydrodynamical simulations with GRASIL-3D

We compute and study the infrared and sub-mm properties of high redshift ($z \gtrsim 1$) simulated clusters and proto-clusters. The results of a large set of hydro-dynamical zoom-in simulations including active galactic nuclei (AGN) feedback, have been treated with the recently developed radiative transfer code GRASIL-3D, which accounts for the effect of dust reprocessing in an arbitrary geometry. Here, we have slightly generalized the code to adapt it to the present purpose. Then we have post-processed boxes of physical size 2 Mpc encompassing each of the 24 most massive clusters identified at z=0, at several redshifts between 0.5 and 3, producing IR and sub-mm mock images of these regions and SEDs of the radiation coming out from them. While this field is in its infancy from the observational point of view, rapid development is expected in the near future thanks to observations performed in the far IR and sub-mm bands. Notably, we find that in this spectral regime our prediction are little affected by the assumption required by this post-processing, and the emission is mostly powered by star formation rather than accretion onto super massive black hole (SMBH). The comparison with the little observational information currently available, highlights that the simulated cluster regions never attain the impressive star formation rates suggested by these observations. This problem becomes more intriguing taking into account that the brightest cluster galaxies (BCGs) in the same simulations turn out to be too massive. It seems that the interplay between the feedback schemes and the star formation model should be revised, possibly incorporating a positive feedback mode.
Inhibition of Phenoloxidase Activity Delays Development in Bactrocera dorsalis (Diptera: Tephritidae)

Abstract Phenoloxidase (PO) is a multicopper enzyme, which plays an important role in melanin synthesis. PO is necessary for defense against intruding microorganisms and parasites, and is important in wound healing and cuticle pigmentation. As a specific inhibitor of PO, kojic acid (KA) is commonly used to characterize the functional properties of PO. In this study, we investigated the effect of KA on PO activity during the development of the oriental fruit fly, Bactrocera dorsalis, which is a destructive pest of many horticultural crops. After feeding on a KA-containing artificial diet, the larval and pupal developmental periods were significantly prolonged. In addition, the larvae did not grow to normal size and rates of pupation and emergence were decreased when B. dorsalis larvae had been fed with KA-containing diet for 6 days. Compared to the control, PO activities from whole bodies of B. dorsalis were inhibited, so did in larval cuticles. Consistent with these, kinetic analysis showed that the catalytic capability of PO was significantly reduced. The I50 values of KA for PO activity also indicated that KA was an effective inhibitor of PO in B. dorsalis. Biochemical characterization showed that PO from B. dorsalis had maximum activity at pH 7.5 and 37 °C. These results provide additional understanding of the role of PO in growth of B. dorsalis. As an inhibitor of PO, KA is capable of disrupting the development of this pest insect.
Nondestructive evaluation sensor fusion with autonomous robotic system for civil infrastructure inspection

Civil infrastructure inspection is crucial to maintaining the quality of that infrastructure, which has a great impact on the economy. Performing this inspection is costly work that requires workers to be trained on how to use varying technologies, which can be error prone when performed manually and can result in damage to the infrastructure in some cases. For this reason, nondestructive evaluation (NDE) sensors are preferred for civil infrastructure inspection as they can perform the necessary inspection without damaging the infrastructure. In this paper, we develop a fully autonomous robotic system capable of real‐time data collection and quasi‐real‐time data processing. The robotic system is equipped with several NDE sensors that allow for a sensor fusion method to be developed that successfully minimizes inspection time while performing adequate inspection of areas that require more in‐depth data to be collected. A detailed discussion of the inspection framework developed for this robotic system, and the dual navigation modes for both indoor and outdoor autonomous navigation is presented. The developed robotic system is deployed to inspect several infrastructures (e.g., parking garages, bridges) at and near by the University of Nevada, Reno campus.
Current changes in tropical precipitation

Current changes in tropical precipitation from satellite data and climate models are assessed. Wet and dry regions of the tropics are defined as the highest 30% and lowest 70% of monthly precipitation values. Observed tropical ocean trends in the wet regime (1.8%/decade) and the dry regions (−2.6%/decade) according to the Global Precipitation Climatology Project (GPCP) over the period including Special Sensor Microwave Imager (SSM/I) data (1988–2008), where GPCP is believed to be more reliable, are of smaller magnitude than when including the entire time series (1979–2008) and closer to model simulations than previous comparisons. Analysing changes in extreme precipitation using daily data within the wet regions, an increase in the frequency of the heaviest 6% of events with warming for the SSM/I observations and model ensemble mean is identified. The SSM/I data indicate an increased frequency of the heaviest events with warming, several times larger than the expected Clausius–Clapeyron scaling and at the upper limit of the substantial range in responses in the model simulations.
