Predicting Literacy Skills at 8 Years From Preschool Language Trajectories: A Population-Based Cohort Study
Authors: Jin Fufen , Schjølberg Synnve , Wang Mari Vaage , Eadie Patricia , Nes Ragnhild Bang , Røysamb Espen , Tambs Kristian 
Published: July 2020

Purpose
This article explored the predictive values of three main language delay (LD) trajectories (i.e., persistent, late onset, and transient) across 3–5 years on poor literacy at 8 years. Additionally, the effect of gender was assessed, using both gender-neutral and gender-specific thresholds.

Method
The data comprised mother-reported questionnaire data for 8,371 children in the Norwegian Mother, Father, and Child Cohort Study. Analyses were conducted using binary logistic regression in SPSS to make predictions about risk.

Results
LD reported at preschool age was associated with excess risk of poor literacy at 8 years with odds ratios ranging from 3.19 to 9.75 dependent on trajectory, persistent LD being the strongest predictor. The odds ratio of transient LD was similar to that of late-onset LD. Gender was not found to play an important role in the association between oral language and literacy, as the gender difference disappeared when gender-specific deficit criterion was used.

Conclusion
Our study supports the longitudinal association between preschool oral language and school-aged literacy skills and highlights the importance of different LD trajectories across preschool ages in predicting later literacy. Furthermore, practitioners are recommended to consider gender-specific cutoffs in relation to language and literacy measures.

Authors: Wolter Julie A. , Gibson Frances E. , Slocum Timothy A. 
Published: July 2020

PurposeThe purpose of this feasibility study was to investigate an early dynamic measure of morphological awareness (MA) involving graduated prompts to measure early MA skill and determine whether this task relates to and predicts performance on other language and/or literacy measures in first-grade children with language abilities typically found in the classroom.MethodIn addition to a battery of language and literacy measures, a dynamic assessment of MA was designed and administered to 74 first-grade children with a range of language abilities.ResultsThe dynamic measure of MA was found to be valid, reliable, and measured early school–age MA performance for children with typical language and those at risk for developmental language disorder. For children with typical language, the developed dynamic MA measure was related to and predictive of performance on other language and literacy measures above and beyond static phonological and MA measures.ConclusionsThe results provide preliminary support for the use of dynamic assessment to measure MA in first-grade children with a range of language abilities.Supplemental Materialhttps://doi.org/10.23641/asha.12591767
Evidenz der Effektivität von Spiegeltherapie bei Phantomschmerzen nach Amputation
Authors: Lemlein Tomas 
Published: July 2020

ZusammenfassungÜber die Hälfte der Patienten nach einer Amputation leidet an Phantomschmerzen, deren Entstehung bislang nicht vollständig geklärt ist. Seit 2019 existiert eine aktualisierte S2k-Leitlinie zur Behandlung neuropathischer Schmerzen 1. Hier wird die Behandlung von Phantomschmerzen mit einem Verweis auf die unzureichende Datenlage nachrangig erwähnt. Die Spiegeltherapie ist eine verbreitet angewandte Behandlung im Rahmen eines multimodalen Konzepts. Zur Klärung der Evidenz für deren Wirksamkeit wurde in drei Datenbanken ausschließlich nach randomisierten klinischen Studien (RCT) gesucht, die die Spiegeltherapie mit einer Kontrollgruppe oder anderen Therapieformen verglichen. Die Schmerzreduktion wurde anhand der visuellen Analogskala, die Studienqualität mithilfe der PEDro-Skala bewertet.Von den sechs in die Analyse eingeschlossenen Studien wiesen fünf einen positiven Effekt der Spiegeltherapie bezüglich der Schmerzstärke und eine Studie eine reduzierte Häufigkeit von Schmerzepisoden nach.Somit besteht moderate Evidenz für die Reduktion von Phantomschmerzen nach Amputation durch die Spiegeltherapie. Zur Bestätigung sind weitere qualitative Studien mit aussagekräftigen Fallzahlen notwendig.
Kinematic and EMG Comparison Between Variations of Unilateral Squats
Under Different Stabilities
Authors: van den Tillaar Roland , Larsen Stian 
Published: July 2020

AbstractThe purpose of the study was to compare kinematics and muscle activity
between two variations of unilateral squats under different stability
conditions. Twelve male volunteers (age: 23±5 years, mass:
80±17 kg, height: 1.81±0.11 m, strength-training experience:
4.3±1.9 years) performed four repetitions with the same external
load (≈4RM). Two variations (with the non-stance leg forwards vs.
backwards) were performed in a Smith-machine and free-weight condition. The
variables were barbell velocity, lifting time and surface electromyography
activity of the lower extremity and trunk muscles during the descending and
ascending phase. The main findings were 1) peak force was higher when
performing the unilateral squats in the Smith machine; 2) peak ascending
barbell velocity increased from repetition 3–4 with free weight; and
3) muscle activity from the rectus femoris, vastus lateral, biceps femoris,
gluteus medius, and erector spinae increased with repetitions, whereas
gluteus, and medial vastus and shank muscles were affected by the
conditions. It was concluded that more peak force could be produced because
of increased stability. However, peak barbell velocity increased from
repetition to repetition in free-weight unilateral squats, which was
probably because the participants grew more comfortable. Furthermore,
increased instability causes more gluteus and vastus medial activation and
foot variations mainly affected the calf muscles.

Published: July 2020

ZusammenfassungWir berichten über den Fall einer 60-jährigen Patientin mit fortgeschrittenem schwerem Lungenversagen bei COVID-19-assoziierter Pneumonie. Die Patientin erhielt zuerst 2 Tage eine (Highflow-)Sauerstoff-Therapie (HFNC) und CPAP, anschließend musste sie intubiert und invasiv beatmet werden. Nach dem Scheitern einer invasiven Beatmung mit schwerster Hypoxämie erfolgte der Anschluss an eine vv-ECMO. Diese wurde über 24 Tage durchgeführt. Die prognostischen Parameter zeigten ab Tag 14 eine günstige Tendenz. Nach Beendigung der ECMO und insgesamt 11 Tagen stundenweiser assistierter Beatmung über Tracheostoma und Sauerstoff (1 l/min) konnte die Patientin in die Rehabilitationsbehandlung verlegt werden. Die letzte Röntgenthoraxaufnahme zeigte eine nahezu vollständige Rückbildung der initialen ausgedehnten beidseitigen Verschattungen. Unser Fall zeigt, dass auch nach einer prolongierten ECMO-Therapie eine Ausheilung der schweren COVID-assoziierten Lungenschäden möglich ist.
Data promiscuity: how the public–private distinction shaped digital data infrastructures and notions of privacy
Authors: Hoeyer Klaus 
Published: July 2020

AbstractThis essay discusses the performative effects of the public–private distinction on digital data infrastructures in healthcare. The words ‘public’ and ‘private’ hold many meanings. This analysis focuses on how they are used both in an informational sense (what is kept secret or strictly controlled versus what is out in the open or shared) and an institutional sense (issues of ownership and purpose such as being state-owned and governed for the common good or privately owned and aimed at generating profit). In the political construction of digital infrastructures, the two senses are deeply intertwined: changes in relation to ownership and purpose affect what is kept secret and what is shared. Furthermore, when policymakers search for ways to protect one aspect (privacy) they sometimes opt for tools from the other (by conceiving of data as private property). The informational interconnectedness facilitated by digital infrastructures produces a form of ‘data promiscuity’. Data promiscuity is a condition where data are indiscriminate in the choice of partners: what is seen as data on a thing for one purpose can always become seen as data on another aspect of that thing and be used for another purpose and by another user. Data are set free to pursue gain or pleasure, but this freedom involves certain dangers for the persons from whom they derive. Data promiscuity is the contemporary condition of possibility for health research. By unpacking the wholesale categories of public and private through which the contemporary situation came about, there is a better chance of rethinking the problems it involves, and for suggesting new solutions to ensure social sustainability. The argument is based on developments in one of the most fiercely digitalised and datafied countries in the world: Denmark.
The problem of distinguishing between a centre and a focus in the space of vector fields with given Newton diagram
Authors: Medvedeva N. B. 
Published: July 2020

Abstract
We investigate the problem of distinguishing between a centre and a focus in the class of analytic vector fields with fixed Newton diagram, which satisfy certain natural conditions of general position. A method is proposed for constructing explicit expressions for the coefficients in the asymptotic representation of the monodromy transformation, known as the Dulac series. These are analogous to the Lyapunov focal quantities. These coefficients make it possible — up to an infinite-codimensional set of exceptional cases — to complete the stability analysis for a compound monodromic (that is, centre-focus) singular point. A computer-aided calculation of formulae for coefficients of the Dulac series is presented. Examples are treated of Newton diagrams with two and three edges.

Authors: Malmström Hans , Enger Jonas , Karlsteen Magnus , Weidow Jonathan 
Published: July 2020

Abstract
How do engineering physics students come to understand and share their physics learnings as a result of careful integration of oral communication with engineering skills like computer aided design and 3D-printing technology? Based in a sociocognitive theory of situated communication pedagogy, the action research conducted in this study set out to answer this research question in an introductory first-year course in engineering physics. A re-design intervention was planned, overseen, and evaluated by a teaching team comprising three physicists and a communication specialist. The findings—supported by student surveys, reflective field notes from the teachers’ observations, and a focus group interview with students—strongly indicate that the students’ structured oral engagement with disciplinary content confer learning benefits and promote the development of disciplinary (physics) literacy.

Published: July 2020

Abstract
The physicochemical properties and the toxicological potential of commercially available MoS2 nanoparticles with different lateral size and degradation stage were studied in the present research work. To achieve this, the structure and stoichiometry of fresh and old aqueous suspensions of micro-MoS2 and nano-MoS2 was analyzed by Raman, while x-ray photoelectron spectroscopy allowed to identify more quantitatively the nature of the formed oxidized species. A, the toxicological impact of the nanomaterials under analysis was studied using adenocarcinomic human alveolar basal epithelial cells (A549 cells) and the unicellular fungus S. cerevisiae as biological models. Cell viability assays and reactive oxygen species (ROS) determinations demonstrated different toxicity levels depending on the cellular model used and in function of the degradation state of the selected commercial nanoproducts. Both MoS2 nanoparticle types induced sublethal damage on the A549 cells though the increase of intracellular ROS levels, while comparable concentrations reduced the viability of yeast cells. In addition, the old MoS2 nanoparticles suspensions exhibited a higher toxicity for both human and yeast cells than the fresh ones. Our findings demonstrate that the fate assessment of nanomaterials is a critical aspect to increase the understanding on their characteristics and on their potential impact on biological systems along their life cycle.

Published: July 2020

Abstract

Objective: The aim of this study was to monitor the physiological changes and cytotoxic effects of exogenous contrast agents during photoacoustic imaging (PAI) and photothermal therapy (PTT). In this paper, a low-power telemetric device for mouse vital signs monitoring was designed and demonstrated. Approach: The power consumption was optimized through hardware and software co-design with a 17% increased operating time compared with typical operation. To demonstrate the feasibility of the monitoring device, PAI and PTT experiments with chitosan-polypyrrole nanocomposites (CS-PPy NCs) as exogenous contrast agents were conducted. Herein, the physiological variation in groups of mice with different CS-PPy NC concentrations was observed and analyzed. Main results: The experimental results indicated the influence of CS-PPy NCs and anesthesia on mouse vital signs in PAI and PTT. Additionally, the association between core temperature, heart rate, and saturation of peripheral oxygen (SpO2) during PAI and PTT was shown. The strong near-infrared absorbance of exogenous contrast agents could account for the increase in mouse core temperature and tumor temperature in this study. Furthermore, high cross-correlation values between core temperature, heart rate, and SpO2 were demonstrated to explain the fluctuation of mouse vital signs during PAI and PTT. Significance: A design of a vital signs monitoring device, with low power consumption, was introduced in this study. A high cross correlation coefficient of mouse vital signs and the effects of CS-PPy NCs were observed, which explained the mouse physiological variation during the PAI and PTT experiments.
Simulation and analysis of III–V heterostructure solar cells for a continuous HVPE process
Authors: Yao Min , Rawlings James B , Kuech Thomas F 
Published: July 2020

Abstract
A continuous hydride vapor phase epitaxy (HVPE) growth system has the potential to realize large-scale production of low-cost III–V solar cells. To aid the process development, this work integrates HVPE reactor model with III–V solar cell simulation to intimately tie the device performance to the process design and operation. This modeling approach sets a potential to connect the control of a growth system directly to the device performance without intervening ancillary models. The approach of direct process-to-device level simulation is demonstrated through simulating the continuous HVPE fabrication of a model solar cell structure as a function of critical process parameter. Critical reactor design features as well as sensitive material parameters in affecting device performance are discussed. An illustrative case study is carried out to investigate the influence of gas curtain velocity on the solar cell efficiency using the integration of reactor and solar cell models. Through the correlations determined by the process-to-device simulations, the sensitivity of critical reactor variables in affecting cell efficiency can be established and optimized through the impact on solar cell performance directly. This integrated device performance–reactor design approach allows for the design of the process and its real-time control with direct knowledge of the expected dependence of device performance on reactor design trade-offs.
On the microstructure and superelastic evolution of laser annealed thin NiTinol wires
Authors: Biffi C A , Coduri M , Tuissi A 
Published: July 2020

Abstract
Shape setting is a crucial step of the production route of shape memory alloys (SMAs) elements for fixing their functional properties. For thin SMA wires, this peculiar setting can be performed by a laser beam scanning the wire length. In the present work the correlation among the functional properties, such as stress–strain curves, the microstructural properties and the laser power was studied on 100 μm pseudoelastic NiTi wire. A comparison between the performances of the laser treated and the commercial wires was discussed. It can be stated that the wire responses can be modulated as a function of the laser power; the optimal laser condition can induce functional properties at least comparable to the ones of the wire conventionally treated in a furnace. Laser induced superelasticity was obtained at room temperature and the corresponding microstructure suggests a texture effect associated with the directional and fast heating induced by the laser beam scan. A favorable condition for extended stress induced plateau lengths, compared to the one of the commercially available furnace treated wires, was induced by the laser scan.
Effect of meso-scale structures and hyper-viscoelastic mechanics on the nonlinear tensile stability and hysteresis of woven materials
Authors: Sun Fengxin , Hu Xiaorui 
Published: July 2020

Abstract
Woven textiles are not only a craft and industrial product but also a thousand-year-old crystallization of human technology. However, the highly sought after mechanical behavior of fabric, generally undergoing large structural distortion along with material deformation even under small stress, is still not clearly understood despite a growing interest in emerging applications, such as flexible electron devices, biomedicine and other engineering fields. Herein, a numerical methodology was introduced to strengthen the comprehensive understanding of the synergy effect of material mechanics and mesostructures of woven materials. A hyper-viscoelastic constitutive model for yarn materials was proposed, and a meso-scale geometry model captured from a resin-cured woven fabric was used, down to micron-sized weaving structures, to investigate the uniaxial loading and unloading process based on finite element (FE) method. The tensile and hysteresis mechanics was identified based on the validated FE model and parameter study of friction effect and fabric structures. The nonlinear tensile and recovery behaviors were reasonably represented by the developed models and the synergistic effect of inner yarn friction and viscoelasticity on the hysteresis was proved. This study can provide an effective method to analyze and predict the nonlinear tensile and hysteresis behavior of woven fabric, laying down the way to textile-based strain sensing materials by enhancing our design and tuning capabilities of the dimension stability of woven materials under tension.

Published: July 2020

Abstract
We have developed the rapid growth method for HgBa2Ca2Cu3O8+δ
(Hg-1223) by using a sealed quartz tube technique with a small amount of cesium chloride (CsCl). Our results suggested that a small amount of CsCl works as a flux during the crystal growth of Hg-1223. The developed method achieved the growth of the Hg-1223 single crystal pieces in 4 h. Furthermore, the grown single crystals showed high purity. The developed method is useful for application purposes such as high transition-temperature (T
c) superconducting cable.
PEWO: a collection of workflows to benchmark phylogenetic placement
Authors: Linard Benjamin , Romashchenko Nikolai , Pardi Fabio , Rivals Eric 
Published: July 2020

Abstract

Motivation
Phylogenetic placement (PP) is a process of taxonomic identification for which several tools are now available. However, it remains difficult to assess which tool is more adapted to particular genomic data or a particular reference taxonomy. We developed Placement Evaluation WOrkflows (PEWO), the first benchmarking tool dedicated to PP assessment. Its automated workflows can evaluate PP at many levels, from parameter optimization for a particular tool, to the selection of the most appropriate genetic marker when PP-based species identifications are targeted. Our goal is that PEWO will become a community effort and a standard support for future developments and applications of PP.
