    Applied Deep Learning: Automated segmentation of White Matter Hyperintensities (WMH) on brain MR images

    Get PDF
    Small vessel disease plays a crucial role in stroke, dementia, and ageing. White matter hyperintensities (WMH) of vascular origin are one of the main consequences of small vessel disease and well visible on brain MR images. Quantification of WMH volume, location, and shape is of key importance in clinical research studies and likely to find its way into clinical practice; supporting diagnosis, prognosis, and monitoring of treatment for dementia and other neurodegenerative diseases. It has been noted that visual rating of WMH has important limitations and hence a more detailed segmentation of WMH is preferred. Various automated WMH segmentation techniques have been developed, to provide quantitative measurements and replace time-consuming, observer-dependent delineation procedures. NLP LOGIX developed an automated algorithm for automatically segmenting white matter hyperintensities using an advanced modeling technique called deep learning

    Hip Adduction Does not Affect VMO EMG Amplitude or VMO:VL Ratios Duringa Dynamic Squat Exercise

    Context: Clinicians commonly attempt to facilitate vastus medialis oblique (VMO) activity by instructing patients to squeeze a ball between their knees during squatting exercises. Objective: To determine whether VMO activation amplitude and the VMO to vastus lateralis (VL) activation ratio (VMO:VL) were altered when performing active hip adduction during a dynamic squat exercise. Design: Single test session. Participants: Fifteen healthy subjects, with no history of knee pain, volunteered for this study.Intervention: Surface EMG of the VMO, VL, and hip adductor (ADD) muscles were recorded while subjects performed 10 consecutive squats against their body weight through a range of 0° to 90° of knee flexion. Subjects performed the squat exercises during two different conditions: (1) active hip adduction and (2) no hip adduction.Main Outcome Measures: Average VMO EMG amplitude and VMO:VL ratio were determined during the knee flexion (0° to 90°) and knee extension (90° to 0°) phases of the squat exercise. Results: Active hip adduction did not significantly change VMO amplitude or VMO:VL ratio during the knee flexion or knee extension phases of the dynamic squat exercise. Conclusions: Based on these results, we conclude that VMO amplitude and the VMO: VL ratio are not influenced by performing active hip adduction during a dynamic squat exercise in healthy subjects. Key words: knee, electromyography, squa

    A Vegan Culture through Social Media: An Autoethnographic Study

    Project Description: This poster presentation will preview the results of an autoethnographic study examining vegan culture in Thailand. The RawTill4 Bike Fest was recently held in Chiang Mai, Thailand; the conference focused on promoting a vegan diet rich in fruits, vegetables and carbohydrates along with daily physical activity—primarily cycling. Two very popular public figures and vegan activists, Harley Johntsone and Leanne Ratcliffe are the keynotes of this conference experience. This unique environment provides hundreds of opportunities for members of the vegan community, cyclists, and/or social media content producers who have established names for themselves on platforms such as YouTube and Instagram, to network and build lasting relationships. Through my participation I had the opportunity to apply knowledge gained through recent coursework in strategic social media and analyze my intercultural experience through digital storytelling. Additionally, there was value in networking with international leaders who presently monetize their use of social media as a means of income, and as a result of this experience I‘ve come away enhanced intercultural and technologically-mediated communication skills that improve the creation, delivery, and reception of the vegan message. By having intentional conversations and engaging in intercultural discovery with other vegan activists, I’ve been able to learn about successful approaches of intercultural and online storytelling used by others. Presenting this project at the Digital Projects Showcase hosted by the Digital Humanities Initiative will allow me to share the details of my research experience with student peers, faculty, and other members of the UNF community

    Interpreter Preparedness for Specialized Settings

    Get PDF
    Sign language interpreters who begin work soon after graduating from post-secondary programs, either associate-level training programs or bachelor-level interpreter education programs are vulnerable to unique challenges for which they may be inadequately prepared, especially if they work as community interpreters in specialized settings. This descriptive study represents the initial attempt to understand how graduates determine personal readiness and identifies contributors to preparedness for working in specialized settings. The sample of recent program graduates provided a snapshot of how prepared interpreters felt in their first years following graduation regarding competency in Legal, Healthcare, Mental Health, Educational, and Deaf-Blind situations. This study highlights specializations in which interpreting graduates feel most and least prepared to work and informs us about the types of instruction or experience that most contributed to their readiness. The results revealed to what extent participants perceived their interpreter education programs prepared them for specialized settings

    The Effects of Small Metal Additions (Co,Cu,Ga,Mn,Al,Bi,Sn) on the Magnetocaloric Properties of the Gd5Ge2Si2 Alloy

    Get PDF
    The structural and magnetic properties of arc-melted and homogenized (1300 °C, 1 h) alloys of Gd5Ge1.9Si2X0.1 (X = Cu, Co, Ga, Mn, Al, Bi, or Sn) were investigated by powder x-ray diffraction, scanning electron microscopy, energy dispersive spectroscopy, and magnetometry. The addition of Cu, Ga, Mn, and Al completely eliminated the large hysteresis losses present in the undoped Gd5Ge2Si2 alloy between 270 and 330 K, broadened the magnetic entropy change ΔSm peak, and shifted its peak value from 275 to 305 K similar to that observed earlier for Gd5Ge1.9Si2Fe0.1. The addition of Bi or Sn had a negligible effect on either the alloy hysteresis losses or the characteristics of the ΔSm vs T peak. The microstructure of the alloy doped with Cu, Co, Ga, Mn, or Al consisted of a majority phase (depleted of silicon) and a minor intergranular phase (rich in silicon and of the corresponding metal additive). For Bi or Sn doping, the microstructure consisted of only the Gd5Ge2Si2 phase. Low temperature x-ray diffraction data on an Fe-doped sample showed the same spectra at 245 and 300 K, consistent with the majority phase possessing an orthorhombic structure. Refrigeration capacity calculations show that Gd5Ge1.9Si2X0.1 (X = Fe,Cu,Co,Ga,Mn, or Al) alloys are superior magnetic refrigerants compared to the undoped Gd5Ge2Si2 alloy
