Purpose:
This study sought to determine whether personality traits related to extraversion and impulsivity are more strongly associated with singers with nodules compared to vocally healthy singers and to understand the relationship between personality and the types of daily speaking voice use.

Method:

Weeklong ambulatory voice recordings and personality inventories were obtained for 47 female singers with nodules and 47 vocally healthy female singers. Paired
t
tests investigated trait differences between groups. Relationships between traits and weeklong speaking voice measures (vocal dose, sound pressure level [SPL], neck surface acceleration magnitude [NSAM], fundamental frequency, cepstral peak prominence [CPP], and the ratio of the first two harmonic magnitudes [
H

–H
2
]) were examined using pairwise Pearson
r
coefficients. Multiple regressions were performed to estimate voice parameters that correlated with two or more traits.

Results:

Singers with nodules scored higher on the Social Potency scale (reflecting a tendency toward social dominance) and lower on the Control scale (reflecting impulsivity) compared to the vocally healthy singers. In vocally healthy singers, vocal dose measures were positively correlated with a combination of Wellbeing (i.e., happiness) and Social Potency, mean SPL was positively correlated with Wellbeing, SPL variability was positively correlated with Social Potency and negatively with Harm Avoidance, and CPP mean was positively correlated with Wellbeing. Singers with nodules had a negative correlation between NSAM skewness and Social Potency. Both groups had negative correlations between

mean and Social Potency and Social Closeness.

Conclusions:
Singers with nodules are more socially dominant and impulsive than vocally healthy singers. Personality traits are related to daily speaking voice use, particularly in vocally healthy singers. Individuals with higher levels of traits related to happiness and social dominance and lower Harm Avoidance tended to speak more, with higher laryngeal forces, with more SPL variability, and with more pressed glottal closure, which could increase risk of phonotrauma.

Published: November 2021

AbstractCyber‐attack has become one of the main threats to the safe operation of the load control system in the distribution network. Currently, a large number of methods are developed to detect cyber‐attacks. However, most of these methods make decisions based on information from a single cyber layer or physical layer. If the decision is wrong, there is no way to verify it. Therefore, if the separate decisions can be made in the cyber layer and physical layer at the same time, and a final judgment is received throughout the two decisions, then the accuracy and credibility of cyber‐attack detection can be improved. First, the particle swarm optimization‐based backpropagation neural network is adopted to detect attacks in the cyber layer, at the same time, the criteria importance though intercrieria correlation‐based grey relational analysis is adopted for the assessment of node risk level in the physical layer. Then, based on the incidence matrix model between the cyber layer and the physical layer, a crosscheck mechanism is proposed to detect the cyber‐attack through the verification of the two decisions. Finally, taking the IEEE 33‐node system as an example, the validity of the proposed method to detect the denial of service attack is verified.

Published: November 2021

AbstractPolymer‐based dielectrics are extensively applied in various electrical and electronic devices such as capacitors, power transmission cables and microchips, in which a variety of distinct performances such as the dielectric and thermal properties are desired. To fulfil these properties, the emerging machine learning (ML) technique has been used to establish a surrogate model for the structure–property linkage analysis, which provides an effective tool for the rational design of the chemical and morphological structure of polymers/nanocomposites. In this article, the authors reviewed the recent progress in the ML algorithms and their applications in the rational design of polymer‐based dielectrics. The main routes for collecting training data including online libraries, experiments and high‐throughput computations are first summarized. The fingerprints charactering the microstructures of polymers/nanocomposites are presented, followed by the illustration of ML models to establish a mapping between the fingerprinted input and the target properties. Further, inverse design methods such as evolution searching strategies and generative models are described, which are exploited to accelerate the discovery of new polymer‐based dielectrics. Moreover, structure–property linkage analysis techniques such as Pearson correlation calculation, decision‐tree‐based methods and interpretable neural networks are summarized to identify the key features affecting the target properties. The future development prospects of the ML‐driven design method for polymer‐based dielectrics are also presented in this review.
Three‐dimensional decoupling imaging method for wideband two‐dimensional multiple‐input‐multiple‐output radar

Published: November 2021

AbstractWideband two‐dimensional multiple input multiple output (MIMO) radar can be used for target three‐dimensional (3‐D) imaging. As the echo of wideband MIMO radar is derived from both time and spatial sampling, the time‐frequency coupling is contained, resulting in imaging defocussing. To solve this problem, a time‐frequency decoupling algorithm based on matrix enhancement and matrix pencil (MEMP) is proposed to achieve high‐resolution 3‐D imaging. By combining the enhanced matrix constructed via MEMP with the modern spectral estimation theory, the time‐frequency coupling term is regarded as a space rotation factor and is eliminated in the process of target position estimation. Simulation results show that the proposed algorithm can reduce the negative influence of time‐frequency coupling and improve the imaging accuracy of wideband two‐dimensional MIMO radar.

Published: November 2021

Context. St 2-22 is a relatively poorly studied S-type symbiotic system that belongs to a small group of jet-producing systems as a result of disc accretion onto a white dwarf fed by its red giant companion.
Aims. The goal of this paper is to analyse the nature and derive the basic parameters of St 2-22, and to follow the jet evolution.
Methods. Photometric monitoring for over 16 yr and high-quality spectroscopic data enabled us to shed new light on its nature. The high-resolution SALT spectra and V Ic photometry obtained during and between the last two outbursts have been used to search for periodic changes, to derive spectroscopic orbits of both system components, and to study the outburst and jet evolution.
Results. We present the orbital and stellar parameters of the system components. The orbital period is Porb = 918 ± 6d. The double-line spectroscopic orbits indicate the mass ratio q = Mg Mh−1 = 3.50 ± 0.53, and the components masses Mgsin3i ∼ 2.35 M⊙ and Mhsin3i ∼ 0.67 M⊙. The orbit shows significant eccentricity, e = 0.16 ± 0.07. The orbital inclination is close to 70°. During outbursts, accelerating and decelerating jets are observed with changes in their radial velocity component in a range from ∼1500 up to nearly 1800 km s−1. St 2-22 turned out to be a classical symbiotic system very similar to the precursor of the group – Z And.

Abstract
Background Especially in rural areas, access of visually impaired people to ophthalmic care and counselling can be limited. The Eye Van is a project supported by the Ministry for Rural Affairs and Consumer Protection Baden-Württemberg which offers visually impaired people an on-the-spot ophthalmological examination and counselling on low-vision aids and social support services. The aim of this project was to evaluate the quality of care provided to visually impaired people in the rural areas of South Baden.
Materials and Methods Between 2016 and 2019, 45 villages in South Baden participated in this project. The visits were advertised in the local press. Appointments were assigned and participant eligibility was assessed over the telephone by the local Federation of the Blind and Partially Sighted in South Baden. During the on-site visits, a medical history was obtained from participants, who then received a comprehensive ophthalmological examination and counselling on low-vision aids and social support services. Interviews were conducted in order to determine the expectations of the participants and to assess their quality of life. A second interview, focused on the measures that had been implemented and changes in the participantsʼ quality of life, was carried out three months later.
Results In total, 264 participants were examined. Of these, 101 participants fulfilled the criteria of moderate/severe visual impairment or blindness defined by the WHO (World Health Organization). The mean age of the visually impaired participants was 85 years. The median decimal visual acuity was 0.08. The median length of time since the participantsʼ last ophthalmological examination was one year. Among the visually impaired participants, 13% did not have any low-vision aids. Their use was recommended to 62% of the visually impaired participants. The main expectation of participants was counselling on low-vision aids and support services. Among all the participants, 42 did one interview and 28 did two interviews. In the second interview, 72% of the participants claimed to have implemented the recommendations. There was no statistically significant change in their quality of life.
Conclusion The access of visually impaired people to ophthalmic care does not seem to be limited in the rural areas of South Baden. Nevertheless, there was a high demand for counselling on low-vision aids and social support services.

ZusammenfassungDas nationale Register „HerediCaRe“ für die Evaluation und Verbesserung der risiko-adjustierten Prävention bei erblichem Brust- und Eierstockkrebs ist eines von sechs vom BMBF geförderten „modellhaften Registern in der Versorgungsforschung“. In diesem Beitrag beschreiben und diskutieren wir die zur standardisierten Datenerfassung gewählte Dokumentations- und IT-Lösung auf der Basis der zuvor definierten speziellen funktionalen Anforderungen. Die Dokumentation gliedert sich in verschiedene patientenindividuell einzusetzende Module, die auf einem zuvor festgelegten Merkmalskatalog beruhen. Aufgrund spezieller funktionaler Anforderungen wurde eine eigene Datenerfassungsanwendung auf der Basis von ORACLE und ORACLE Forms entwickelt und implementiert. Die speziellen Anforderungen umfassten u. a. die Einbindung grafischer Stammbaumdarstellungen, den strukturierten Upload von Stammbaumdaten und molekulargenetischen Informationen, die automatisierte Altdatenübernahme aus dem Vorgängersystem, sowie die freie Programmierbarkeit von beliebig komplexen Datenbankabfragen zur zentralen Datenqualitätsprüfung. In die Anwendung ist eine Datenbank zur patienten-unabhängigen Verwaltung genetischer Risikovarianten nahtlos integriert und mit den patientenbezogenen Daten verknüpft. Die Vor- und Nachteile der gewählten IT-Lösung werden kritisch diskutiert. Insgesamt kommen wir zu der Schlussfolgerung, dass es angesichts der komplexen Dokumentation und der speziellen Funktionsanforderungen alternativ keine fertigen Softwareprodukte zu der von uns gewählten Eigenentwicklung existieren.

AbstractA direct C–H halogenation of 3-aryl-1H-pyrazol-5-amines using N-halogenosuccinimides (NXS; X = Br, I, Cl) in dimethyl sulfoxide at room temperature has been developed. This transformation provides an effective metal-free protocol for the synthesis of novel 4-halogenated pyrazole derivatives with moderate to excellent yields. The method utilizes NXS reagents as cheap and safe halogenating reagents under simple and mild reaction conditions, it has broad substrate scope, and can be used for gram-scale synthesis. The utility of this procedure is established by further transformations of the 4-halogenated products. Mechanism studies show that DMSO plays a dual role of catalyst and solvent.

Clinical Practice Patterns of Speech-Language Pathologists Delivering Dysphagia Services to Persons with COPD: Analysis of Survey Outcomes
Authors: Drulia Teresa , Hodge Alexis 
Published: November 2021

AbstractSwallowing impairments co-occur with chronic obstructive pulmonary disease (COPD) leading to aspiration, disease exacerbations, and malnutrition. This pilot survey study aimed to identify current clinical practice patterns for swallowing evaluation and treatment in persons with COPD. A 35-question Qualtrics survey was deployed to medical speech-language pathology (SLP) social media sites and professional boards; flyers were distributed at a professional conference. Forty-eight SLPs completed the study. SLPs routinely include a clinical swallow examination (96%), videofluoroscopic swallowing study (79%), adjunctive respiratory measures (respiratory rate [83%], and pulse oximetry [67%], respiratory–swallow pattern [77%]) but less frequently include fiberoptic endoscopic evaluation of swallowing (23%). Self-reported advanced clinical experience and expert respiratory analysis skills were associated with adjunctive respiratory measure (respiratory rate, pulse oximetry) inclusion during assessment. Compensatory strategy training (77%) is a preferred treatment for dysphagia in COPD; however, respiratory–swallow pattern training and expiratory muscle strength training are increasing in use. SLPs self-report a comprehensive, individualized patient-centered care approach with inclusion of adjunctive respiratory-focused methods in dysphagia evaluation and treatment practice in persons with COPD. Advances in the identification of the integral role of respiratory function in swallowing integrity may be translating to clinical practice methods for dysphagia management in persons with COPD.

Protamine—The Journey from DNA to Heparin Neutralization to Gene therapy
Authors: Thachil Jecko 
Published: November 2021

AbstractProtamine is now well recognized as a key heparin neutralizing agent. However, protamine was discovered over a century ago, during experiments performed to uncover the secrets behind heritability. Although protamine was discovered as a highly charged protein, it did not receive the attention it deserved until the dawn of insulin era, when it was used to create the neutral protamine Hagedorn formulation. Based on the same principles, protamine was identified to neutralize heparin and has since been used successfully for many years in cardiothoracic surgery. More recently, its clinical applications have extended to gene therapy. In this historical sketch, the journey from the discovery of protamine, onwards to heparin neutralization, and up to its utilization in genetic modulatory treatments is detailed.

Published: November 2021

Abstract
Objective We describe the design, implementation, and validation of an online, publicly available tool to algorithmically triage patients experiencing severe acute respiratory syndrome coronavirus (SARS-CoV-2)-like symptoms.
Methods We conducted a chart review of patients who completed the triage tool and subsequently contacted our institution's phone triage hotline to assess tool- and clinician-assigned triage codes, patient demographics, SARS-CoV-2 (COVID-19) test data, and health care utilization in the 30 days post-encounter. We calculated the percentage of concordance between tool- and clinician-assigned triage categories, down-triage (clinician assigning a less severe category than the triage tool), and up-triage (clinician assigning a more severe category than the triage tool) instances.
Results From May 4, 2020 through January 31, 2021, the triage tool was completed 30,321 times by 20,930 unique patients. Of those 30,321 triage tool completions, 51.7% were assessed by the triage tool to be asymptomatic, 15.6% low severity, 21.7% moderate severity, and 11.0% high severity. The concordance rate, where the triage tool and clinician assigned the same clinical severity, was 29.2%. The down-triage rate was 70.1%. Only six patients were up-triaged by the clinician. 72.1% received a COVID-19 test administered by our health care system within 14 days of their encounter, with a positivity rate of 14.7%.
Conclusion The design, pilot, and validation analysis in this study show that this COVID-19 triage tool can safely triage patients when compared with clinician triage personnel. This work may signal opportunities for automated triage of patients for conditions beyond COVID-19 to improve patient experience by enabling self-service, on-demand, 24/7 triage access.
Experimental study of a 100-W all-fibre amplifier operating near 980 nm
Authors: Chen M. , Du H. , Cao J. , Liu A. , Pan Zh. , Huang Zh. , Chen J. 
Published: November 2021

Abstract
A 100-W all-fibre amplifier operating near 980 nm is demonstrated with a double-clad Yb-doped fibre (DCYF) having a 60/125-μm core/cladding diameter. By preliminarily optimising the length of DCYF (about 1.4 m), a total output power of about 113.4 W is obtained with 9-W seed light, the peak-to-peak suppression of 1030-nm ASE being about 21.5 dB. The effect of active fibre length is studied using the experimental setup. With the help of spectrum integration, it is found that while the total output power decreases, the output power around 980 nm is enlarged with the active fibre (i.e., DCYF) further shortened to 1.2 m, which is due to better suppression of 1030-nm ASE. It means that the effect of 1030-nm ASE cannot be simply neglected when its peak-to-peak suppression is lower than 30 dB. The effect of seed power on the output properties of the amplifier is also studied experimentally. It is found that a stronger seed power is beneficial to the 1030-nm ASE suppression and slope efficiency improvement. Then, with the 1.2-m DCYF and 14-W seed power, the largest output signal power around 980 nm (estimated about 108.2 W) is eventually obtained and the peak-to-peak suppression of 1030-nm ASE is more than 33 dB at the maximum output power. The pertinent results can provide significant guidance for the design and study of a 980-nm laser and other sorts of three-level fibre laser.

AbstractFree carrier absorption of optical radiation in layers of an AlGaAs/GaAs heterostructure is studied by the method of probe radiation coupling in order to determine the absorption cross section parameter in the AlGaAs material with a high (22%) aluminium concentration. For this purpose, we have fabricated special samples based on AlGaAs/GaAs heterostructures simulating an n-type-doped laser waveguide with carrier concentrations in the range 5 × 1016− 3 × 1017cm−3. The doping profile and the composition and thickness of layers are measured and the temperature and spectral dependences of the absorption coefficient are studied. It is shown that an increase in temperature and in the probe wavelength leads to an increase in the absorption in the heterostructure layers.

Abstract
We report the results of the analysis of experiments on dynamic phase correction of laser radiation distorted by a turbulent airflow in an adaptive optical system (AOS) with a Shack–Hartmann wavefront sensor (WFS). A field-programmable gate array is used as the main AOS control element, which provides a closed loop AOS bandwidth of up to 2000 Hz. The WFS is used to estimate the characteristic bandwidth of the generated turbulence ν
turb. Changes in the spatial and temporal spectra of the laser radiation phase, as well as the quality of the beam during its dynamic phase correction at various AOS frequencies, are analysed. It is shown experimentally and by calculation that to ensure a high efficiency of the wavefront correction, the AOS frequency should be at least 20 times higher than ν
turb.
