Use Of The Lower Extremity Functional Scale (LEFS) In A Patient After A First Metatarsophalangeal Joint Implant: A Case Report

First metatarsolphalangeal (MTP) total joint implants are uncommon; however, hemi implants have increased in popularity. The. HemiCAP® (Franklin, MA) implant resurfaces the metatarsal head while leaving the distal phalanx intact. While early results of the HemiCAP(®) implant surgery have been promising, physical therapy outcome measures such as the LEFS have not been extensively studied in this population. The Lower Extremity Functional Scale (LEFS) is a sensitive and reliable outcome measure that has commonly been used in patients with hip and knee dysfunction. While the LEFS has been used for a broad spectrum of lower-extremity pathologies, there is a paucity of research that investigates the use of LEFS in patients who have had a first MTP joint implant. The purpose of this case report was to investigate the use of LEFS in a patient with first MTP HemiCAP® joint implant.https://dune.une.edu/pt_studcrposter/1072/thumbnail.jp

The Role of Emotionally-Supportive Teacher Beliefs and Behavior in Student Aggression

Overt aggression is a pervasive problem in schools. In 2017 alone, the US Department of Education reported over 360,000 aggressive incidents. According to the General Aggression Model, emotion regulation plays a key role in aggression. Teachers play a role in student regulation through their supportive (e.g., expressive-encouragement) and unsupportive (e.g., punitive) responses to students. This study examined the role of the classroom teacher in student aggression. Teacher emotion-focused beliefs about both the reasons for aggression and the effectiveness of emotionally-supportive responses to aggression, were explored. Teacher likelihood of mental health referral for anger and fighting (i.e., an emotion and behavior linked to aggression) was examined as a predictor of aggression. An additional predictor for student aggression, student perception of teacher response to student emotion (i.e., supportive, unsupportive) was examined. Participants consisted of fourth and fifth-grade students (n = 398) and their teachers (n = 22) from eight schools (five public, three charter) across five school districts in a midwestern state. The teacher-report assessed student aggression, emotion dysregulation, and general beliefs about aggression. The child-report assessed perception of teacher responses to student emotion. Data was analyzed using non-parametric analysis and hierarchical linear modeling. Teachers reported believing that emotion expression was the most likely reason for student aggression and that supportive responses to aggressive behavior (i.e., emotion discussion, referral for mental health support) were more effective than punitive responses. Student perception of teacher supportive response to student emotion (i.e., problem-focused, expressive encouragement) was negatively associated with student aggression, and student perception of teacher unsupportive response to student emotion (i.e., minimization, punishment) was positively associated with student aggression, after accounting for student emotion dysregulation, sex, race, and a race by emotion dysregulation interaction

SECURE AND FULLY TRANSPARENT ROAMING FOR LONG RANGE

Roaming with Long Range wide-area network (LoRaWAN) requires connections to home Network Servers (hNS), serving Network Servers (sNS) and forwarding Network Servers (fNS) across LoRa domains. Today, this entails a tedious manual process for generating the keys, certificates and configuration files to connect these servers on a peer-to-peer basis. This means that manual configurations grow quadratically with the number of LoRa networks involved. In addition, today there is no way to enable roaming across LoRa networks dynamically (i.e., not if these pre-configurations among the visited and the home/serving LoRa networks aren\u27t in place). Accordingly, presented herein are techniques to scale LoRaWAN roaming linearly, while not only automating the entire roaming process, but also allowing the acceptance of dynamic roaming requests. Opposite to conventional arrangements, such as roaming hubs, where roaming partners need to adhere to the hub\u27s rules for packet routing, service levels and trust, the techniques presented herein act transparently to the servers, keeping routing and data exchanges under the control of each peer

An fNIRS Study of the Effects of Medication on Cognitive Functioning and Cerebral Hemodynamics in Adults with Attention-Deficit/Hyperactivity Disorder

Background: Current research indicates clear distinctions between the general population and individuals diagnosed with Attention-Deficit/Hyperactivity Disorder (ADHD), specifically in cognitive processes and physiological brain activity. Stimulant medications have been shown to improve and, in some cases, normalize dysfunction in both these areas. The majority of extant brain imaging literature has included functional magnetic resonance imaging (fMRI) in tandem with neuropsychological tests to explore these relationships. However, functional near-infrared spectroscopy (fNIRS) is a promising neuroimaging technology that offers some unique features including portability, ecological validity, and the ability to detect brain activity via concentrations of oxygenated and deoxygenated blood. Very few studies have used fNIRS as a tool to investigate the impact of medication on adults with ADHD, both in their cognitive functioning and brain hemodynamics. However, there is evidence that this technology may—in addition to providing novel information about cognitive and physiological functioning—actually be better suited to evaluating the ADHD population.Objectives: The present study sought to: 1) compare differences in cognition (using neuropsychological tests) and neurophysiology (using fNIRS) between adults withADHD (when unmedicated) and age-, gender-, and education-matched healthy control(HC) adults, and 2) compare differences in cognition and neurophysiology betweenmedicated and unmedicated states in adults with ADHD. Ultimately, the goal was to investigate the potential application of fNIRS as an assessment tool for both diagnostic(of the physiological underpinnings of the disorder) and monitoring (of the effectiveness of cognition-improving medications) purposes.Participants: Nine individuals aged 18-25 diagnosed with ADHD and nine age-, gender-, and education-matched healthy control participants (HCs).Method: All participants completed two testing sessions. HCs completed both sessions under normal conditions whereas ADHD participants completed one testing session while medicated and the other while unmedicated. Cognitive testing focused on working memory, a domain relevant to ADHD. Testing included 1) a two-subtest WAIS-IV; 2) a Sternberg delayed recognition task (a test of working memory); and 3) a visual n-back task (another working memory test). The latter two tasks were completed while participants were connected to a continuous wave fNIRS system to record cerebral hemodynamic activity during working memory performance. Demographic variables, confirmation of diagnosistic status, medications, and recent daily activities regarding caffeine, alcohol, tobacco, and other behaviors that could impact fNIRS data were recorded.Results: Cognitively, while healthy controls performed better on working memory tasks than ADHD participants, and ADHD participants generally performed better when medicated than unmedicated, neither comparison reached significance. Physiologically, there were no significant differences in PFC activation between the HC and ADHD groups, nor between medicated and unmedicated states within the ADHD group.Conclusions: The findings of this study mirror previous findings of the cognitive effects of medication in ADHD. Not surprisingly, individuals with ADHD performed working memory tasks less accurately and more slowly than controls and the intake of stimulant medication led to an improvement in performance that reached levels similar to healthy individuals. By contrast, the medication-induced working memory improvements among adults with ADHD were not reflected in corresponding physiological changes measured by fNIRS. The lack of significant findings in this study may be due to low statistical power, though alternative explanations are also explored. Nonetheless, before fNIRS can contribute to clinical diagnosis and treatment of ADHD, more research is needed to establish its clinical application.M.S., Psychology -- Drexel University, 201

Slak-in-Du project. Inventarisatie van de mollusken in de duingebieden langs de Belgische Kust - 2012 Oostkust

The Slak-in-Du (Snails in the Dunes) project aims at establishing, over a period of about six years, a new inventory of the molluscan fauna in the Belgian coastal dunes area. In the first year of the project the eastern part of the Belgian coast was investigated, i.e. the region east of the harbor of Zeebrugge. About 20 persons have contributed in one way or another. The results are very satisfactorily: A total of 30 species of land snails (among which 5 species of slugs), but also 6 species of freshwater molluscs and 5 species preferring brackish waters were observed. More than half of the species of land snails observed are reported for the first time since 1950 or even for the first time ever for the UTM (Universal Transverse Mercator) 10 x 10 km squares that were investigated, i.e. ES18, ES28 en ES29. The most important of these is undoubtedly Vertigo angustior, a protected species which was found for the first time in more than 50 years at the eastern part of the Belgian coast and for the first time ever in the nature reserve “Het Zwin”. Four other species are reported for the first time in the region that was investigated, i.e. Zonitoides nitidus, Cochlicella acuta, Cernuella cisalpina (= C. jonica) and Alinda biplicata biplicata. The latter had, moreover, never been observed before in the Belgian coastal area. Five species were found rather frequently, i.e. Monacha cantiana, Candidula intersecta, Cernuella virgata, Theba pisana and Cepaea nemoralis. The data that were collected further clearly show that Cochlicella acuta and Theba pisana pisana have by now spread along the entire Belgian coast. On the other hand, several species that are thought to be in decline at the Belgian coast, i.e. Monacha cartusiana, Helicella itala itala, Candidula gigaxii, and Candidula unifasciata unifasciata, have not been observed at all. As only one specimen of Cernuella aginnica was found, also this species is probably in decline. Since only few freshwater habitats occurred in the areas that were investigated in 2012 only a limited number of freshwater species is reported here. Finally, as to brackish water snails, the very rare species Limapontia depressa and Assiminea grayana were found in the “Bay of Heist”, while one specimen of Ecrobia ventrosa was observed alive in the nature reserve “Het Zwin”

Analysis of complex singularities in high-Reynolds-number Navier-Stokes solutions

Numerical solutions of the laminar Prandtl boundary-layer and Navier-Stokes equations are considered for the case of the two-dimensional uniform flow past an impulsively-started circular cylinder. We show how Prandtl's solution develops a finite time separation singularity. On the other hand Navier-Stokes solution is characterized by the presence of two kinds of viscous-inviscid interactions that can be detected by the analysis of the enstrophy and of the pressure gradient on the wall. Moreover we apply the complex singularity tracking method to Prandtl and Navier-Stokes solutions and analyze the previous interactions from a different perspective

Space Propulsion Design and Analysis

This software provides an improved methodology for predicting launcher base pressure and heat loads for RSRM (Reusable Solid Rocket Motor) launchers by accounting for complex anisotropic stress/strains and variable turbulent Prandtl and Schmidt numbers. A "building block" approach to turbulence model development, and validation has been applied for improved missile/launcher base region analysis. Modifications to existing kappa - epsilon turbulence models and application of scalar variance models are incorporated into a RANS-based method for aeropropulsive flow modeling, directly related to base flow methodology. (RANS stands for Reynolds-averaged Navier-Stokes.) The models are applied in a RANS solver framework and can improve analysis of other complex flow fields. The enhanced models provide a more accurate predictive capability for improving the design and analysis of RSRM launcher configuration. The kappa - epsilon model enhancements have been shown to improve the capability for predicting turbulence effects in base blow environments. The scalar variance models have been assessed over a wide range of flow configurations to improve prediction of turbulent scalar mixing

ARRIVING CONTAINER CARGO PRIORITIZATION METHOD

Maritime freight is undergoing a fast transformation with regard to the technology that can be carried by containers, such as sensors, transponders, etc., which can allow for better identification of containers and their condition. However, the correlation between goods carried in containers, their environmental needs, and their state upon arrival still involves manual processes. Techniques herein propose a method for maritime containers to express an unloading/opening urgency based on the reported status of individual merchandise units carried inside containers
