Exploring the Clinical Feasibility of Alternative Word-Understanding Measures for Autistic Children With Minimal Spoken Language
Authors: Muller Kristen 
Published: April 2023

Purpose:
The primary aim of this study was to explore the clinical feasibility of using alternate word-understanding assessment modalities for autistic children who have minimal verbal skills. Specifically, assessment duration, occurrence of disruptive behavior, and no-response trials were examined across three word-understanding assessment conditions: a low-tech condition, a touchscreen condition, and a condition that used real-object stimuli. A secondary aim was to examine the relationship between disruptive behavior and assessment outcomes.

Method:
Twenty-seven autistic children between the ages of 3 and 12 years who had minimal verbal skills completed 12 test items on the three assessment conditions. Repeated-measures analyses of variance with post hoc Bonferroni procedures were used to describe and compare assessment duration, occurrence of disruptive behavior, and no-response trials across conditions. A Spearman rank-order correlation coefficient was used to examine the relationship between disruptive behavior and assessment outcomes.

Results:
The real-object assessment condition took significantly longer than the low-tech and touchscreen conditions. Participants engaged in disruptive behavior most frequently during the low-tech condition; however, differences among conditions were not significant. There were significantly more no-response trials in the low-tech condition than in the touchscreen condition. There was a significant, weak negative correlation between disruptive behavior and experimental assessment outcomes.

Conclusion:
Results show there is promise in using real objects and touchscreen devices to assess word understanding in autistic children who have minimal verbal skills.
Crowdsourced Perceptual Ratings of Voice Quality in People With Parkinson's Disease Before and After Intensive Voice and Articulation Therapies: Secondary Outcome of a Randomized Controlled Trial
Authors: McAllister Tara , Nightingale Christopher , Moya-Galé Gemma , Kawamura Ava , Ramig Lorraine Olson 
Published: April 2023

Purpose:
Limited research has examined the suitability of crowdsourced ratings to measure treatment effects in speakers with Parkinson's disease (PD), particularly for constructs such as voice quality. This study obtained measures of reliability and validity for crowdsourced listeners' ratings of voice quality in speech samples from a published study. We also investigated whether aggregated listener ratings would replicate the original study's findings of treatment effects based on the Acoustic Voice Quality Index (AVQI) measure.

Method:
This study reports a secondary outcome measure of a randomized controlled trial with speakers with dysarthria associated with PD, including two active comparators (Lee Silverman Voice Treatment [LSVT LOUD] and LSVT ARTIC), an inactive comparator (untreated PD), and a healthy control group. Speech samples from three time points (pretreatment, posttreatment, and 6-month follow-up) were presented in random order for rating as “typical” or “atypical” with respect to voice quality. Untrained listeners were recruited through the Amazon Mechanical Turk crowdsourcing platform until each sample had at least 25 ratings.

Results:
Intrarater reliability for tokens presented repeatedly was substantial (Cohen's κ = .65–.70), and interrater agreement significantly exceeded chance level. There was a significant correlation of moderate magnitude between the AVQI and the proportion of listeners classifying a given sample as “typical.” Consistent with the original study, we found a significant interaction between group and time point, with the LSVT LOUD group alone showing significantly higher perceptually rated voice quality at posttreatment and follow-up relative to the pretreatment time point.

Conclusions:

These results suggest that crowdsourcing can be a valid means to evaluate clinical speech samples, even for less familiar constructs such as voice quality. The findings also replicate the results of the study by Moya-Galé et al. (
2022
) and support their functional relevance by demonstrating that the effects of treatment measured acoustically in that study are perceptually apparent to everyday listeners.

Authors: Bartoldus Regina 
Published: April 2023

ZUSAMMENFASSUNGEinerseits sichern eine Hämo- oder eine Peritonealdialyse das Überleben von Patienten mit einer chronischen Nierenerkrankung, andererseits beeinflussen diese Dialysemethoden die Lebensqualität der Betroffenen. Ziel dieser Studie ist es, die Auswirkungen der Hämo- und Peritonealdialyse auf die Lebensqualität von chronisch nierenkranken Menschen aufzuzeigen und Zusammenhänge bezüglich des Alters, Geschlechts und des Zeitraums der Dialysebehandlung zu untersuchen. Hierzu wurde ein quantitativ-deskriptives Studiendesign gewählt. Die Ergebnisse zeigen, dass die Lebensqualität von Menschen mit einer chronischen Niereninsuffizienz, die eine Peritonealdialyse durchführen, insgesamt signifikant höher ist als bei Personen, die einer Hämodialyse bedürfen. Im Gegensatz zum Status quo der Forschung konnte der Einfluss der Faktoren Alter, Geschlecht und Dauer der Behandlung auf die Lebensqualität nicht bestätigt werden. Die Studiendaten indizieren für die vermehrte Durchführung der Peritonealdialyse, da diese eine bessere Lebensqualität für die Betroffenen bietet.

Bloodstream Infections with Opportunistic Pathogens in COVID-19 Era: A Real Challenge Necessitates Stringent Infection Control
Authors: Guchhait Partha , Chaudhuri Bhaskar Narayan , Das Satadal 
Published: April 2023

Abstract
Background: Bloodstream infections (BSI) due to opportunistic microbes in the coronavirus disease 2019 (COVID-19) pandemic lead to high morbidity and mortality among hospitalized patients. Thus, it is vital to find out the risk factors of BSI and to learn the ways to mitigate it.
Aim: The aim of this study was to evaluate important risk factors of BSI due to opportunistic pathogens and to assess the role of the rigid infection control program to deal with this issue.
Methods: A prospective, cross-sectional study was performed for 6 months on 150 patients admitted in both COVID-19 and non-COVID-19 intensive care units of our hospital. BSI was confirmed by the BACTEC and Vitek 2 compact system. Prospective surveillance and environmental sampling were carried out for source tracking along with rigorous infection control measures and the outcome was analyzed.
Findings: Burkholderia cepacia, Elizabethkingia meningoseptica, Candida auris, vancomycin-resistant Enterococcus, and Achromobacter xylosoxidans were the common opportunistic pathogens isolated from a single or paired blood sample(s) in our study. Key risk factors were prolonged intensive care unit stay, central venous access, mechanical ventilation, immune-compromised condition, and use of biologics. Reverse osmosis water and used normal saline bottles were the common environmental source of infection. Following the implementation of precise infection control measures, there was a sharp decline in BSI cases, which was not attributed to the downfall of COVID-19 cases.
Conclusion: Combined prospective surveillance and environmental sampling helped to find out the sources and implementation of an intensive and insistent infection control program that are needed to control opportunistic pathogens mediated BSI.

Translation invariant diagonal frame decomposition of inverse problems and their regularization
Authors: Göppel Simon , Frikel Jürgen , Haltmeier Markus 
Published: April 2023

Abstract
Solving inverse problems is central to a variety of important applications, such as biomedical image reconstruction and non-destructive testing. These problems are characterized by the sensitivity of direct solution methods with respect to data perturbations. To stabilize the reconstruction process, regularization methods have to be employed. Well-known regularization methods are based on frame expansions, such as the wavelet–vaguelette decomposition, which are well adapted to the underlying signal class and the forward model and furthermore allow efficient implementation. However, it is well known that the lack of translational invariance of wavelets and related systems leads to specific artifacts in the reconstruction. To overcome this problem, in this paper we introduce and analyze the translation invariant diagonal frame decomposition (TI-DFD) of linear operators as a novel concept generalizing the singular value decomposition. We characterize ill-posedness via the TI-DFD and prove that a TI-DFD combined with a regularizing filter leads to a convergent regularization method with optimal convergence rates. As illustrative example, we construct a wavelet-based TI-DFD for one-dimensional integration, where we also investigate our approach numerically. The results indicate that filtered TI-DFDs eliminate the typical wavelet artifacts when using standard wavelets and provide a fast, accurate, and stable solution scheme for inverse problems.

Published: April 2023

Abstract
It is well known that the traditional two-dimensional electron system (2DES) hosted by the SrTiO3 substrate can exhibit diverse electronic states by modifying the capping layer in heterostructures. However, such capping layer engineering is less studied in the SrTiO3-layer-carried 2DES (or bilayer 2DES), which is different from the traditional one on transport properties but more applicable to the thin-film devices. Here, several SrTiO3 bilayers are fabricated by growing various crystalline and amorphous oxide capping layers on the epitaxial SrTiO3 layers. For the crystalline bilayer 2DES, the monotonical reduction on the interfacial conductance, as well as carrier mobility, is recorded on increasing the lattice mismatch between the capping layers and epitaxial SrTiO3 layer. The mobility edge raised by the interfacial disorders is highlighted in the crystalline bilayer 2DES. On the other hand, when increasing the concentration of Al with high oxygen affinity in the capping layer, the amorphous bilayer 2DES becomes more conductive accompanied by the enhanced carrier mobility but almost constant carrier density. This observation cannot be explained by the simple redox-reaction model, and the interfacial charge screening and band bending need to be considered. Moreover, when the capping oxide layers have the same chemical composition but with different forms, the crystalline 2DES with a large lattice mismatch is more insulating than its amorphous counterpart, and vice versa. Our results shed some light on understanding the different dominant role in forming the bilayer 2DES using crystalline and amorphous oxide capping layer, which may be applicable in designing other functional oxide interfaces.
Feasibility of size-specific organ-dose estimates based on water equivalent diameter for common head CT examinations: a Monte Carlo study
Authors: Tahiri M , Benameur Y , Mkimel M , El Baydaoui R , Mesardi M R 
Published: April 2023

Abstract
Computed tomography dose index (CTDI) is an unreliable dose estimate outside of the standard CTDI phantom diameters (16 and 32 cm). Size-specific dose estimate (SSDE) for head computed tomography (CT) examination was studied in the American Association of Physicists in Medicine Report 293 to provide SSDE coefficient factors based on water equivalent diameter as size metrics. However, it is limited to one protocol and for a fully irradiated organ. This study aimed to evaluate the dependency of normalized organ dose (ND) on water equivalent diameter as a size metric in three common protocols: routine head, paranasal sinus, and temporal bone. CTDIw measurements were performed for outlined protocols in the Siemens Emotion 16-slice-configuration scanner. Geant4 Application for Tomographic Emission Monte Carlo simulation platform, coupled with ten GSF patient models, was used to estimate organ doses. CT scanner system was modeled. Helical CT scans were simulated using constructor scan parameters and calculated scan lengths of each patient model. Organ doses provided by simulations were normalized to CTDIvol. The water equivalent diameters (D
w) of patient models were obtained via relationships between D
w and both effective diameter for a sample of patients’ data.NDs received by fully, partially, and non-directly irradiated organs were then reported as a function of D
w. For fully irradiated organs, brain (R
2 > 0.92), eyes (R
2 > 0.88), and eye lens (R
2 > 0.89) correlate well with D
w. For the rest of the results, a poor correlation was observed. For partially irradiated organs, the exception was scalp (R
2 = 0.93) in temporal bone CT. For non-directly irradiated organs, the exception was thyroid (R
2 > 0.90) and lungs (R
2 > 0.91) in routine head CT. ND correlates well in routine head CT than other protocols. For the most part, no relationship seems to exist between R
2 and scan percentage coverage. The results have revealed additional factors that may influence the ND and D
w relationship, which explains the need for more studies in the future to investigate the effect of scan conditions and organ anatomy variation.

Abstract
The anisotropic transport properties of gallium telluride (GaTe) have been reported by several experiments, giving rise to many debates recently. The anisotropic electronic band structure of GaTe shows the extreme difference between the flat band and tilted band in two distinct directions,

, and which we called as the mixed flat-tilted band (MFTB). Focusing on such two directions, the relaxation of photo-generated carriers has been studied using the non-adiabatic molecular dynamics (NAMD) method to investigate the anisotropic behavior of ultrafast dynamics. The results show that the relaxation lifetime is different in flat band direction and tilted band direction, which is evidence for the existence of anisotropic behavior of the ultrafast dynamic, and such anisotropic behavior comes from the different intensities of electron–phonon coupling of the flat band and tilted band. Furthermore, the ultrafast dynamic behavior is found to be affected strongly by spin–orbit coupling (SOC) and such anisotropic behavior of the ultrafast dynamic can be reversed by SOC. The tunable anisotropic ultrafast dynamic behavior of GaTe is expected to be detected in ultrafast spectroscopy experiments and it may provide a tunable application in nanodevice design. The results may also provide a reference for the investigation of MFTB semiconductors.

Published: April 2023

Abstract
Tomography is applied daily to bolometric data in magnetically controlled nuclear fusion devices to infer important quantities of the studied plasmas, such as the emissivity profiles or the radiated power in different locations of the main chamber. Tomographic reconstructions are also crucial for power balance analysis and to estimate heat fluxes for turbulence studies. One of the issues, associated with any tomographic technique, resides in the ill-posed nature of the mathematical problem, meaning that more than one possible emissivity profile is compatible with the measurements within the estimated uncertainties. Therefore, a careful evaluation of the quality of the obtained reconstructions is an important step of the analysis. On Joint European Torus (JET), since the two cameras are located in different toroidal locations, axial symmetry of the plasma radiation must be assumed to perform traditional tomographic reconstructions. Such a specific hypothesis, however, cannot be guaranteed in the case of symmetry-breaking mechanisms, such as strong local gas puffing for fuelling. The present contribution addresses this problem of local plasma fuelling, focusing on the observed significant mismatch between measured and back-calculated projections in specific pulses, including the last JET DT campaign (DTE2) carried out in 2021. The analysis indicates that the observed discrepancy, due to the gas injected primarily from valves located in the same octant where one of the bolometer arrays is located, can be rectified acceptably well by a physically-based correction. The sensible improvements in the bolometric maximum likelihood tomography’s outputs are also documented, and the possible physical explanation for such a phenomenon is discussed. The study performed in this article is expected to have a significant impact on the analysis of JET data and on the physical interpretation of the results obtained during the recent DTE2 experiments, for which a proper evaluation of the radiated power estimates is of non-negligible relevance.
Influence of magnetic field gradient on the capacitive argon discharge at 8 MHz and 40 MHz

Published: April 2023

Abstract
A one-dimensional implicit particle-in-cell/Monte Carlo collision model is used to study the effects of magnetic field gradients on the capacitively coupled argon plasma at 8  MHz and 40 MHz. The magnetic field strength at the powered electrode is fixed at 10 G, while varies from 30 to 100 G at the grounded electrode. The simulations show that the magnetic field with variable gradient can produce controllable asymmetry in the plasma density and ion flux profiles to each electrode. Increasing the magnetic field gradient will generate a significant dc self-bias, which results in a large ion bombardment energy at the powered electrode. The magnetic field gradients have been demonstrated to be an approach to create the dc self-bias and also effectively improve the plasma density. It is also found that at a higher frequency of 40 MHz, the dc self-bias voltage decreases, due to the fact that high collision rate of electrons with background gas will disturb the cyclotron motion of electrons, so the effect of the magnetic field is weakened. As a result, the ability to independently control ion energy and flux is weakened.

Published: April 2023

Abstract
As the failure of bolt connections by corrosion can result in major disasters and cause casualties and property damage, monitoring bolted joints is of great importance. However, current researches on lamb wave based bolted joint monitoring mainly focused on single-input-single-output (SISO) systems, which require a long diagnosis time and numerous transducers. To reduce the number of transducers on monitoring, the multiple-input systems, i.e. multiple-input-multiple-output (MIMO) system and multiple-input-single-output (MISO) system, can be adopted. However, both multiple-input systems are prone to failure due to the interference among the excited waves generated from multiple simultaneously-operated actuators. To remove such interference, an orthogonal variable spreading factor (OVSF) code based bolted joint monitoring method is proposed here. Firstly, instead of using the same detection signal, multiple detection signals generated using OVSF codes are emitted from different input ports. Then, for each considered input port, the corrosion information carrying waveforms are recovered from the acquired signals via timing acquisition and demodulation and utilized to reveal the status of the bolted joints via wavelet packet based analysis. To validate the proposed method, experiments with a MIMO system (i.e. three-input-two-output system) and a MISO system (i.e. six-input-single-output system) were conducted to simultaneously reveal six given bolted joint corrosion status in this research. Since the proposed method effectively suppresses the interference, the MIMO/MISO bolted joint monitoring system can present a performance similar to that of the SISO monitoring system but require fewer transducers.

Published: April 2023

Abstract
Since the discovery of Fe-based superconductors, a lot of effort has been devoted to growing single crystals and epitaxial thin films of them for fundamental studies and applied research of superconductivity. As a result, epitaxial thin films of the most of Fe-based superconductors have been realized. However, some of the materials, namely pristine and transition-metal-doped (Li,Fe)OHFeSe, hydrogen-doped LnFeAsO (Ln = Nd and Sm), Co-doped SmFeAsO, and K-doped BaFe2As2 have been available only in the form of single crystals due to, e.g. the difficulty in doping hydrogen, obtaining high-quality sintered bulks for the target used for pulsed laser deposition, and controlling volatile elements. By solving those issues, the aforementioned compounds have been successfully fabricated as epitaxial thin films in recent years. Unlike single crystals, transport critical current measurements are relatively easy on thin films, which can help evaluate the application potential. In this article, we give an overview over the growth methods for epitaxial thin films of those compounds, followed by their physical properties, especially focusing on electrical transport.
