Survey Results of Speech-Language Pathologists Working With Cognitive-Communication Disorders: Improving Practices for Mild Cognitive Impairment and Early-Stage Dementia From Alzheimer's Disease
Authors: Lanzi Alyssa M. , Saylor Anna K. , Cohen Matthew L. 
Published: May 2022

Purpose:
As the incidence of Alzheimer's disease (AD) continues to rise, there is a need for interventions that focus on risk reduction and early disease management. Speech-language pathologists (SLPs) can contribute to risk reduction efforts and deliver cognitive interventions; however, the nature and frequency of current clinical practice in those areas is unclear. Therefore, the purpose of this study was to conduct an exploratory survey of the cognitive-communication practices and needs of SLPs for adults with mild cognitive impairment (MCI) and early-stage dementia from AD, to inform future research and clinical training efforts.

Method:
SLPs completed an online survey that assessed five areas of practice specific to cognitive-communication and MCI and early-stage dementia: (a) education and training, (b) MCI subtype knowledge and consideration, (c) goals and treatment practices, (d) assessment of everyday living skills, and (e) general clinical practices and needs.

Results:
One hundred fifty-seven SLPs completed the survey and represented a range of practice experience. Results revealed a discrepancy between the number of SLPs who provide services to adults with MCI or early-stage dementia and those who have received formal training to do so, suggesting a reliance on clinical practice experience. Participants primarily reported using interview and informal methods to assess daily activities and often described using compensatory-based treatments.

Conclusions:
These findings contribute to the limited knowledge about SLPs' cognitive-communication practices to help improve early-disease management for AD, a rapidly growing population in need of SLPs' services. More research is needed to support SLPs in being maximally effective when working with clients early in the AD continuum.

Transcranial Direct Current Stimulation Paired With Verb Network Strengthening Treatment Improves Verb Naming in Primary Progressive Aphasia: A Case Series
Authors: Sheppard Shannon M. , Goldberg Emily B. , Sebastian Rajani , Walker Alexandra , Meier Erin L. , Hillis Argye E. 
Published: May 2022

Purpose:
There are few evidence-based treatments for language deficits in primary progressive aphasia (PPA). PPA treatments are often adopted from the poststroke aphasia literature. The poststroke aphasia literature has shown promising results using Verb Network Strengthening Treatment (VNeST), a behavioral therapy that focuses on improving naming by producing verbs and their arguments in phrases and sentences. Emerging research in poststroke aphasia and PPA has shown promising results pairing behavioral language therapy with transcranial direct current stimulation (tDCS).

Method:
This study used a double-blind, within-subjects, sham-controlled crossover design to study the effect of anodal tDCS applied to left inferior frontal gyrus (IFG) plus VNeST versus VNeST plus sham stimulation in two individuals with nonfluent variant PPA and one individual with logopenic variant PPA. Participants received two phases of treatment, each with 15 1-hr sessions of VNeST. One phase paired VNeST with tDCS stimulation, and one with sham. For each phase, language testing was conducted at baseline, and at 1 week and 8 weeks posttreatment conclusion. For each participant, treatment efficacy was evaluated for each treatment phase by comparing the mean change in accuracy between baseline and the follow-up time points for naming trained verbs (primary outcome measure), untrained verbs, and nouns on the Object and Action Naming Battery. Mean change from baseline was also directly compared between tDCS and sham phases at each time point.

Results:
Results revealed a different pattern of outcomes for each of the participants. A tDCS advantage was not found for trained verbs for any participant. Two participants with nonfluent variant PPA had a tDCS advantage for generalization to naming of untrained verbs, which was apparent at 1 week and 8 weeks posttreatment. One participant with nonfluent variant also showed evidence of generalization to sentence production in the tDCS phase.

Conclusion:
VNeST plus anodal tDCS stimulation of left IFG shows promising results for improving naming in PPA.

Published: May 2022

AbstractDeep learning (DL) has attracted significant attention in partial discharge (PD) pattern recognition of gas‐insulated switchgear (GIS). However, the existing DL method extracts numerical information and ignores spatial correlation information. In addition, once the sample size is reduced, model performance is severely degraded. To address these issues, a novel capsule deep graph convolutional network (CDGCN) is employed for GIS PD pattern recognition. First, the GIS PD data is transformed to graph data. Then, the CDGCN is established for GIS PD pattern recognition. The introduction of a ChannelSortPooling layer enriches the graph representation information and filters out the feature values with higher information content. In addition, the multi‐view graph representation is converted to a capsule form, and a capsule network with stronger feature extraction capability is introduced to improve the accuracy of the final graph representation. The results reveal that the proposed CDGCN can effectively diagnose the GIS PD and is more accurate than the traditional DL method. The proposed CDGCN can handle small samples pattern recognition problems and provides a reliable reference for GIS PD pattern recognition.

AbstractIn this research work, an adaptive TS‐fuzzy based RBF neural network (ATSFRBFNN) algorithm based maximum power point tracker (MPPT) is employed for grid integrated photovoltaic (PV) system. The novel learning algorithm provides accurate and rapid PV power tracking under fluctuating solar insolation. However, an improved damping circulating current limiting inverter controller is employed to generate gating signal of voltage source inverter and to deliver reduced harmonic constant, less power loss, mitigation of power quality issues regulation of Dc‐link voltage utilization for grid integrated PV system under steady, and transient weather conditions. The experimental results justify the improved system performance under varying operating conditions. The behaviour of novel hybrid PV MPPT structure is compared with TS‐fuzzy, RBFNN, and GA‐RBF for higher tracking efficacy, least tracking deviation, accurate responses, and zero steady‐state power oscillation around MPP region.
Fast multidimensional dictionary learning algorithms and their application in 3D inverse synthetic aperture radar image restoration and noise reduction

AbstractBy generalising dictionary learning (DL) algorithms to multidimensional (MD) mode and using them in applications where signals are inherently multidimensional, such as in three‐dimensional (3D) inverse synthetic aperture radar (ISAR) imaging, it is possible to achieve much higher speed and less computational complexity. In this study, the formulation of the multidimensional dictionary learning (MDDL) problem is expressed and two algorithms are proposed to solve it. The first one is based on the method of optimum directions (MOD) algorithm for 1D dictionary learning (1DDL), which uses alternating minimisation and gradient projection approach. As the MDDL problem is non‐convex, the second algorithm approximates the non‐convex objective with a new jointly convex function and efficiently solves it. As an application, we use the proposed methods to restore and denoise the ISAR image. Numerical experiments highlight that the proposed algorithms, in addition to reducing the computational complexity and the amount of required memory, also entail less training data for learning the dictionary, and enjoy higher convergence speed in comparison to their one‐dimensional (1D) counterparts. Specifically, convergence speed of MD algorithms, depending on the size of the training data, is up to at least 10.7 times faster than the equivalent 1DDL algorithm. According to the simulation results, the SNR value achieved by the proposed algorithms is higher than the case where we use the 3D‐IFFT for image reconstruction and the case of fixed dictionaries, by approximately 12 and 4 dB, respectively.

Context. Stellar coronal mass ejections (CMEs) are the primary driver of exoplanetary space weather and may affect the habitability of exoplanets. However, detections of possible stellar CME signatures are extremely rare.
Aims. This work aims to detect stellar CMEs from time-domain spectra observed through the LAMOST Medium-Resolution Spec-troscopic Survey (LAMOST-MRS). Our sample includes 1 379 408 LAMOST-MRS spectra of 226 194 late-type main-sequence stars (Teff < 6000 K, log[g/(cm s−2)] > 4.0).
Methods. We first identified stellar CME candidates by examining the asymmetries of Hα line profiles and then performed double Gaussian fitting for Hα contrast profiles (differences between the CME spectra and reference spectra) of the CME candidates to analyse the temporal variation in the asymmetric components.
Results. Three stellar CME candidates were detected on three M dwarfs. The Hα and Mg I triplet lines (at 5168.94 Å, 5174.13 Å, and 5185.10 Å) of candidate 1 all exhibit a blue-wing enhancement, and the corresponding Doppler shift of this enhancement shows a gradually increasing trend. The Hα line also shows an obvious blue-wing enhancement in candidate 2. In candidate 3, the Hα line shows an obvious red-wing enhancement, and the corresponding projected maximum velocity exceeds the surface escape velocity of the host star. The lower limit of the CME mass is estimated to be ~8 × 1017 g to 4 × 1018 g for these three candidates.

Authors: Lenarz T. , Büchner A. , Illg A. 
Published: May 2022

ZusammenfassungCochlea-Implantate stellen heute eine unverzichtbare Methode zur auditiven Rehabilitation hochgradig hörgeschädigter Patienten dar. Durch die rasante Entwicklung der Implantat-technologie haben sich die Hörergebnisse erheblich verbessert, ca 80% der Patienten können telefonieren und Kinder erreichen eine nahezu normale Hör- und Sprachentwicklung. Das hat zu einer Indikationsausweitung hin zu Patienten mit Hochtontaubheit und einseitiger Taubheit geführt. Zur Zeit sind aber nur etwa 60 000 der ca 1 Million CI-Kandidaten implantiert. Zukünftig werden multimodale universelle Hörimplantate für die kombinierte elektro-mechanische Stimulation zur Verfügung stehen, die fortlaufend eine Anpassung der Stimulationsstrategie an den jeweiligen Funktionszustand von Haarzellen und Hörnerven auch bei progredienter Schwerhörigkeit ermöglichen. Brain-Computer-Interfaces erlauben die automatisierte Anpassung an die Hörsituation und eine Optimierung der Signalverarbeitung zur Erzielung eines bestmöglichen Hörvermögens. Binaurale Hörsysteme erlauben eine Verbesserung von Richtungshören und Hören im Störgeräusch. Advanced Implants besitzen additiv gefertigte individualisierte Elektroden, die sich nach atraumatischer robotisch assistierter Insertion aktiv der Anatomie der Cochlea anpassen. Sie sind in Abhängigkeit von der Pathophysiologie mit integrierten biologischen Komponenten ausgestattet, unterstützen die Erhaltung des Restgehörs und ermöglichen die Regeneration neuraler Elemente zur Verbesserung der Elektroden-Nerven-Schnittstelle. Dadurch lassen sich die heutigen grundsätzlichen Grenzen der CI-Technologie überwinden und in Richtung des physiologischen Gehörs verschieben. Das Bionische Ohr ist somit in Reichweite. Durch konsequente Weiterentwicklung mit Vereinfachung der Versorgung, hörerhaltender Implantation unter Lokal-Anästhesie und Anwendung robotischer Systeme werden zukünftig mehr Patienten von dem neuen physiologischen Hören profitieren.

Published: May 2022

Abstract
Background Raised complication rates have been reported for total hip arthroplasty (THA) in posttraumatic hip joints after acetabular fractures with prior open reduction and internal
fixation (ORIF). The present study evaluated (I) postoperative surgical site infection and the risk of early infection following THA in posttraumatic hip joints after acetabular fractures
and (II) the discriminatory ability of preoperative C-reactive protein (CRP) blood levels for periprosthetic joint infection (PJI).
Materials and Methods Patients were included who had undergone THA (2014–2019) after prior ORIF, and nonsurgically treated acetabular fractures. Patients’ demographics and the
duration between fracture and THA implantation were assessed. Preoperative diagnostic testing (laboratory results, hip aspirations) as well as the results of intraoperative microbiological
swabs and sonication were also evaluated. Postoperative complications were recorded.
Results Sixty-seven patients (51 men/16 women) were included, with a mean age of 54.7 ± 14.0 years (range: 18.0–82.9). The mean time between acetabular fracture and THA was
13.5 ± 14.9 years (0.2–53.5). Four subgroups were classified: subgroup I (nonsurgical, n = 15), subgroup II (complete removal of osteosynthesis, n = 8), subgroup III (partial removal of
osteosynthesis, n = 15), and subgroup IV (remaining osteosynthesis, n = 29). Preoperative CRP blood levels were normal. CRP levels had no discriminatory ability to predict PJI (AUC: 0.43).
Positive microbiological swabs were assessed in subgroups III (n = 1) and IV (n = 2). Complications during follow-up occurred in subgroups I (one aseptic loosening [6.7%]), III (one wound
revision [6.7%], two low-grade infections [13.3%]), and IV (three low-grade infections [10.3%]).
Conclusion High infection rates were found in patients with THA after acetabular fracture with remaining implants or partial implant removal. Serum CRP alone seems to be a poor
predictor. Therefore, an extensive diagnostic algorithm can help to detect an occult infection, including preoperative hip aspiration (microbiological samples and measurements of synovial
CRP, WBC, and alpha-defensin levels). Intraoperative tissue samples and sonication results should be obtained during THA implantation.

Abstract
Introduction Arthrogryposis is characterized by the presence of multiple contractures at birth and can be caused by pathogenic variants in TTN (Titin). Exons and variants that are not expressed in one of the three major isoforms of titin are referred to as “metatranscript-only” and have been considered to be only expressed during fetal development. Recently, the metatranscript-only variant (c.39974–11T > G) in TTN with a second truncating TTN variant has been linked to arthrogryposis multiplex congenita and myopathy.
Methods Via exome sequencing we identified the TTN c.39974–11T > G splice variant in trans with one of three truncating variants (p.Arg8922*, p.Lys32998Asnfs*63, p.Tyr10345*) in five individuals from three families. Clinical presentation and muscle ultrasound as well as MRI images were analyzed.
Results All five patients presented with generalized muscular hypotonia, reduced muscle bulk, and congenital contractures most prominently affecting the upper limbs and distal joints. Muscular hypotonia persisted and contractures improved over time. One individual, the recipient twin in the setting of twin-to-twin transfusion syndrome, died from severe cardiac hypertrophy 1 day after birth. Ultrasound and MRI imaging studies revealed a recognizable pattern of muscle involvement with striking fibrofatty involvement of the hamstrings and calves, and relative sparing of the femoral adductors and anterior segment of the thighs.
Conclusion The recurrent TTN c.39974–11T > G variant consistently causes congenital arthrogryposis and persisting myopathy providing evidence that the metatranscript-only 213 to 217 exons impact muscle elasticity during early development and beyond. There is a recognizable pattern of muscle involvement, which is distinct from other myopathies and provides valuable clues for diagnostic work-up.

Published: May 2022

AbstractA ligand-free, palladium-catalyzed ortho-deuteration of aromatic carboxylic acids was developed using D2O as the deuterium source. Compared to their meta-substituted analogues, an unusually lower reactivity in para- and ortho-substituted benzoic acids toward hydrogen isotope exchange was observed. Further investigation revealed that the reaction temperature is a critical parameter for the reactivity, and the modified conditions can afford deuterated products with good to excellent deuterium incorporation.
Magnification in Periodontics: An Overview
Authors: Durgapal Surabhi , Shetty Mamatha 
Published: May 2022

AbstractA plethora of changes in the concept and the techniques in dental sciences and an increase in patient awareness have spawned demand in advanced dental treatment encompassing elimination of disease with more precision and less discomfort. The use of magnification systems like microscopes is widespread in the medical field, and now it has successfully spread its wings in dentistry. Visual enhancement by using loupes or surgical microscopes can render refinement in the basic surgical procedures. Magnification periodontics refers to the wide range of procedures performed by the use of magnification systems like loupes and microscopes that allow convergence of ideas and efforts, which can make a huge impact on patients. Periodontal procedures are being increasingly performed nowadays that have enabled enhanced outcomes, which were difficult to achieve with the macrosurgery procedures when wound healing and tissue trauma are in consideration. The surgical operating microscope works within the microsurgical triad that includes illumination increased precision and magnification. The incorporation of smaller instruments and sutures and better visualization of the operating site enhance the surgical skills of the clinician. In the past decade, various periodontal procedures from the removal of calculus to the placement of dental implants have been performed using the surgical microscope, which have invariably provided favorable results. It is a topic of interest in the future of periodontal therapy.
The design of a high-voltage, long-pulse width, flat-top compensation pulse generator based on metal oxide varistors

Published: May 2022

In recent years, the pulse forming technology based on metal oxide varistors (MOVs) has been verified to be an effective way to generate high-voltage quasi-square pulses. Due to the limited varistor voltage of a single MOV brick, multiple MOV bricks connected in series are required to stabilize a pulse with high amplitude (larger than hundreds of kV), which leads to the rise of the series inductance of the MOV branch and the flat-top droop in the output waveform. This paper provides two solutions to reduce the influence of the MOV branch inductance on output waveforms. One is that a coaxial evolute structure of the MOV bricks connected in series is designed, which can not only improve the insulation capacity but also reduce the branch inductance. Another is that a flat-top compensation scheme named “PFN-MOV” (Pulse Forming Network) is proposed, which adds an LC filtering branch to shape the signal into a flat-top rising wave with ripple and then offsets the flat-top droop caused by the inductance of the MOV branch. Based on the above ideas, a high-voltage, long-pulse width, flat-top compensation pulse generator is designed and tested, and a quasi-square pulse with voltage amplitude of more than 500 kV, pulse width greater than 800 ns, rise time of less than 50 ns, and flat top of about 600 ns is obtained experimentally. This MOV based generator has the advantage of simple design, compact construction, and better flat top, which is promising to be used as a compact long-pulse driver in many fields, such as high-current accelerator, industrial dedusting, medical sterilization, and cancer treatment.
A method to improve multi-node power transmission efficiency of inductively coupled mooring cable
Authors: Zheng Yu , Zhang Shijiang , Fei Chen , Ren Yuanhong , Liu Yingjie 
Published: May 2022

The inductively coupled mooring cable is an important tool for monitoring the ocean hydrological data. The mooring cable is an open-loop structure that uses a section of seawater as the transmission medium. The power transmission efficiency of this structure is very low due to the large power loss of the seawater medium, and it is rarely studied. In this paper, a contactless power transmission circuit with seawater loss is analyzed, and the theoretical model of multi-node power transmission of the inductively coupled mooring system is established. In this model, the improvement of the output power and transmission efficiency is only related to the frequency selection and the properties of the magnetic core itself, such as the magnetic core material. Moreover, the optimal scheme is selected according to the output power requirements. The experimental results show that when the input current (Irms) is 2 A, the output power of a single node is 12 W, the total output power is 120 W, and the total transmission efficiency reaches 50%.
