Clinical Application of the SADL Scale in Private Practice II: Predictive Validity of Fitting Variables
Authors: Hosford-Dunn Holly , Halpern Jerry 
Published: February 2022

AbstractPredictive validity of 44 independent variables and their interactions with Satisfaction with Amplification in Daily Life (SADL) scores was assessed. SADL scores were influenced by patient age, years of hearing aid experience, hours of use per day, perceived hearing difficulty, pure-tone average, hearing aid style, processor type, and manufacturer's invoice cost. The relative importance of these variables to SADL measures was complex and very small, but the variables and their squares and interactions improved r2 predictions of SADL Global and subscale scores in a separate stepwise multiple linear regression procedure by 12 to 33 percent compared to SADL norms alone. More research with additional variables is needed to develop a clinically useful model for predicting wearer satisfaction. Clinically, SADL scores yield subscale-specific patterns of satisfaction and dissatisfaction that help in intervention planning and serve as graphic "snapshots" of satisfaction status. A series of patient profiles are presented illustrating the potential usefulness of the SADL in predicting hearing aid satisfaction. With its good construct and psychometric properties, the SADL could serve as a gold standard for satisfaction outcomes and a basis for development of a predictive model of hearing aid fitting success.

Strategies Used in Feigning Hearing Loss
Authors: Martin Frederick N. , Champlin Craig A. , McCreery Tiana M. 
Published: February 2022

AbstractThirty unsophisticated participants with normal hearing were paid to simulate a hearing loss according to their success in "deceiving" the examiner. The behaviors that these "malingerers" manifested are described . A post-examination interview revealed the strategies used by these participants, which may reflect those strategies used by patients who truly attempt to feign a hearing loss .

Some Issues Relevant to Establishing a Universal Newborn Hearing Screening Program
Authors: Gorga Michael P. , Preissler Kimberly , Simmons Jeff , Walker Lisa , Hoover Brenda 
Published: February 2022

AbstractThis article describes some of the factors relevant to the establishment of a universal newborn hearing screening (UNHS) program. First, the difficulty in providing precise estimates of test sensitivity and specificity are reviewed. This section is followed by hypothetical estimates of overall programmatic costs, first for a fixed number of babies to be screened and then as a function of the number of babies to be screened in a year. Included in these estimates are the costs for equipment, disposables, personnel, and follow-up testing. These estimates are provided for three different screening protocols: auditory brainstem response (ABR) alone, otoacoustic emission (OAE) alone, and OAE followed by ABR only for those babies who failed the OAE screening. If follow-up costs are not included, it is less expensive to screen newborns with OAEs compared with the other two protocols. However, once follow-up testing is included as part of the program costs and there are at least 400 births per year, procedures in which OAEs are performed first, followed by an ABR on those infants who do not pass the OAE test, result in the lowest costs. Hospitals with as few as 400 births per year should expect per-baby costs not exceeding $30, regardless of which protocol is used. For all three protocols, the unit costs decrease as the number of babies screened increases. The final section describes data from a local UNHS program in which all infants are screened first with an OAE test, followed by an ABR test on infants not passing the OAE screening. Idiosyncratic features to this program are described, including the fact that all screening tests are performed by audiologists, who are paid on a part-time basis, adding cost to the program. Even under these circumstances, the unit cost is under $30. These data lead us to conclude that all infants can be screened in a cost-effective manner.

Barriers and facilitators of translating health research findings into policy in sub-Saharan Africa: A Scoping Review
Authors: Damba Florence Upenyu , Mtshali Ntombifikile Gloria , Chimbari Moses John 
Published: February 2022

AbstractDespite efforts made by sub-Saharan Africa (SSA) countries to promote evidence-informed health policymaking, translating research evidence into policy remains a very challenging task fraught with many barriers. However, to achieve the goal of making more evidence-informed decisions to improve health, it is critical to overcome the barriers to the translation of research into policy. This paper provides an overview of the barriers and facilitators of translating research into policy in SSA countries to understand why research findings are sometimes not translated into policy and makes suggestions for improving the situation. Arksey and O’Malley’s five-step methodological framework guided the scoping review process. Primary research literature published in English between January 2010 and March 2021 was systematically searched using PubMed, Google Scholar, Web of Science and EBSCO host search engines. We focused on articles that reported on the barriers to and facilitators of translating research findings into policy. Two hundred and twenty-three articles were identified but 162 articles met the eligibility criteria. Of those that met the eligibility criteria, 73 were excluded after reading the title and abstract. After title and abstract screening, a further 70 articles were excluded thus remaining with only 19 articles from 16 SSA countries that were given a full review through data extraction and thematic analysis. The most common barriers identified were limited capacity by policymakers to use evidence, inaccessibility of research evidence, lack of high-quality usable evidence and use of policy briefs alone. Although translation of research findings into policy is fraught with a multitude of barriers, there are means to overcome them such as the availability of research results, strengthened capacity for evidence use, the establishment of a department of research within the Ministry of Health, appropriate packaging of research results, use of policy briefs, stakeholder feedback meetings and annual research dissemination conferences where policy briefs are discussed and distributed. Where funding is limited research should be policy driven instead of open-ended to avoid wasting resources. It is imperative to have a comprehensive approach to reduce barriers whilst enhancing facilitators that may improve the translation of research findings into policy.
Transformation of polarisation singularities in nonlinear mixing of light beams with frequency conversion in a medium with cubic nonlinearity
Authors: Grigoriev K.S. , Makarov V.A. 
Published: February 2022

AbstractWe analyse the electric field transverse distributions in light beams with a tripled frequency and with a frequency of 2ω1–ω2, which arise in the bulk of an isotropic cubic-nonlinear medium upon the propagation of nonuniformly polarised beams of fundamental radiation with a multimode transverse structure described by a superposition of Laguerre – Gaussian modes. A relation is found between the total topological indices of the circular polarisation singularity points in the transverse sections of the generated signal beams and the corresponding total indices in the beams of fundamental radiation.

Abstract
Single-cascade 1.56-to-2.84 μm SRS conversion is demonstrated in a hollow-core revolver fibre filled with methane at a pressure of 25 atm under pumping by positively chirped pulses of a high-power erbium-doped all-fibre laser. At a maximum pump pulse energy of 34 μJ (average power 3.74 W) and a pump pulse duration of about 260 ps, ultrashort pulses (USPs) with a duration of 110 ps and an energy of 1.33 μJ (average power 133 mW) are achieved at the centre wavelength of 2.84 μm. The gas fibre Raman lasers based on hollow-core fibres with pumping by high-power fibre sources are promising for producing all-fibre systems emitting USPs in the mid-IR range.

Published: February 2022

Background Our aims were to describe characteristics of sexual function prior to and 6 months following benign hysterectomy in patients with three common surgical indications, and to identify preoperative factors that influence the magnitude and direction of change in sexual function after the procedure. Methods This prospective observational cohort study enrolled women (n = 80) undergoing hysterectomy for benign indications. Patients were categorised into three groups according to surgical indication: (1) pelvic pain (PP), (2) abnormal uterine bleeding (AUB), and (3) pelvic organ prolapse (POP). Primary outcome was Female Sexual Function Index (FSFI), which patients completed preoperatively and 6 months postoperatively. Results The study included 80 patients, of whom 25.0% (n = 20) had surgical indication of PP, 46.3% (n = 37) of AUB, and 28.7% (n = 23) of POP. PP patients experienced a significant improvement in overall sexual function, as well as orgasm and pain domains following hysterectomy. Significant improvements were not found in AUB and POP patients. In multivariate analysis, lower baseline sexual function (P < 0.001), younger age (P = 0.013), and pelvic pain <6 months (P = 0.020) were each independently associated with improvement in sexual function, but surgical indication was not significant. Conclusion Individual patient factors including younger age, lower baseline sexual function, and short duration of pelvic pain are associated with a higher likelihood of improvement in sexual function after hysterectomy. Surgical indication does not appear to be predictive of postoperative sexual function once accounting for other factors.
An empirical study on integrating a small humanoid robot to support the therapy of children with Autism Spectrum
Disorder and Intellectual Disability
Authors: Conti Daniela , Trubia Grazia , Buono Serafino , Di Nuovo Santo , Di Nuovo Alessandro 
Published: February 2022

Abstract
Recent research showed the potential benefits of robot-assisted therapy in treating children with Autism Spectrum
Disorder. These children often have some form of Intellectual Disability (ID) too, but this has mainly been neglected by previous
robotics research. This article presents an empirical evaluation of robot-assisted imitation training, where the child imitated
the robot, integrated into the Treatment and Education of Autistic and related Communication handicapped Children (TEACCH)
program. The sample included six hospitalized children with different levels of ID, from mild to profound. We applied mixed
methods to assess their progress, during treatment and three months later. Results show increased Gross Motor Imitation skills in
the children, except for those with profound ID and the therapists’ positive attitude towards the humanoid robot. Furthermore, the
therapists suggest how a robot could be used to autonomously collect and analyze the information obtained in the rehabilitation
training for a continuous evaluation of the participants.
Languages for learning

Published: February 2022

Abstract
More than 25 years have passed since CLIL was first introduced in schools all over Europe with objectives, methods and organizational structures that often also vary from one country to another. Time has passed, and still without a precise framework of reference, CLIL shows its great potential as well as its drawbacks. Using data from research conducted in Italy with four CLIL teachers who teach physics through a foreign language, this article aims to highlight the possibility that CLIL can serve to make every teacher, regardless of the subject, aware of the role that language can play in learning. The data collected, which refer to the Italian education system, emphasize the central role of the subject teacher in CLIL implementation. They also draw attention to the need for important changes in the CLIL agenda for the coming years.
Standardizing conductor surface roughness for DC gas-insulated equipment-a careful analysis on local morphology
Authors: Chen Geng , Xu Hao , Xu Yongsheng , Shao Yuming , Wang Cong , Li Chuanyang , Tu Youping 
Published: February 2022

Abstract
The gas ionization inside the gas-insulated electric power equipment increases the gas conduction current and introduces charges to the spacer surface, which results in local electric field enhancement and potentially triggers spacer flashover. In this letter, we demonstrated that micro protrusions in a finely finished conductor surface plays a significant role in inducing local gas ionization, resulting in an increased local gas conduction current. A gas conduction current using conductors with higher surface kurtosis S
ku was found approximately 10 times higher than that using an electrode with a similar S
a but a different machining procedure. The piecewise nonlinear relation between the maximum local field strength and the average roughness was calculated over different kurtosis ranges. A conductor surface roughness evaluation method which combines average height of peak S
pa with extreme probability of deviation from mean height of peak S
pku was put forward.
Retracted: A density functional theory investigation on the Au-decorated zinc oxide nanosheet as a chemical sensor for mesalamine drug detection
Authors: Rajhi Ali A , Alamri Sagr , Ebadi Ghaffar 
Published: February 2022

Abstract
We employed density functional B3LYP to inspect the impact of Au-decoration on a ZnO nanosheet (ZnONS) sensing performance in detection of mesalamine (MSA) drug. The interaction of the pristine ZnONS with the MSA was found to be weak, and the sensing response is about 2.8. Decorating an Au atom into the ZnONS surface increases the adsorption energy (Ead) of MSA from −5.7 to −23.7 kcal/mol. The sensing response significantly rises to 77.3 by Au-decoration. A short recovery time of 18.6 s is found for the MSA desorption from the Au-decorated ZnONS surface at 298 K. The water solvent reduces Ead of MSA to −17.8 kcal mol−1. Thus, it suggests that Au-decorated ZnONS may be highly sensitive MSA sensor with a short recovery time.
X-Ray Fine Structure of a Limb Solar Flare Revealed by Insight-HXMT, RHESSI and Fermi

Published: February 2022

Abstract
We conduct a detailed analysis of an M1.3 limb flare occurring on 2017 July 3, which have the X-ray observations recorded by multiple hard X-ray telescopes, including Hard X-ray Modulation Telescope (Insight-HXMT), Ramaty High Energy Solar Spectroscopic Imager (RHESSI), and the Fermi Gamma-ray Space Telescope (Fermi). Joint analysis has also used the extreme ultraviolet (EUV) imaging data from the Atmospheric Imaging Assembly (AIA) aboard the Solar Dynamic Observatory. The hard X-ray spectral and imaging evolution suggest a lower corona source, and the non-thermal broken power law distribution has a rather low break energy ∼15 keV. The EUV imaging shows a rather stable plasma configuration before the hard X-ray peak phase, and accompanied by a filament eruption during the hard X-ray flare peak phase. Hard X-ray image reconstruction from RHESSI data only shows one foot point source. We also determined the DEM for the peak phase by SDO/AIA data. The integrated EM beyond 10 MK at foot point onset after the peak phase, while the >10 MK source around reconnection site began to fade. The evolution of EM and hard X-ray source supports lower corona plasma heating after non-thermal energy dissipation. The combination of hard X-ray spectra and images during the limb flare provides the understanding on the interchange of non-thermal and thermal energies, and relation between lower corona heating and the upper corona instability.
The Preliminary Statistical Analysis of LAMOST DR8 Low Resolution AFGK Stars
Authors: Chen Y. H. , Li G. W. , Shu H. 
Published: February 2022

Abstract
We download the Large sky Area Multi-Object fiber Spectroscopic Telescope Data Release 8 (LAMOST DR8) low resolution catalog for 6,478,063 AFGK type stars and plot the figures of effective temperature, gravitational acceleration and metal abundance. Some small and medium mass stars are evolved from pre-main sequence or main sequence stage to planetary nebula stage or white dwarf stage by the stellar evolution code MESA. We analyze the observed statistical data and model calculation results, and then obtain some basic conclusions preliminarily. Most red giant and asymptotic giant branch stars with log g less than 0.85 have poor metal abundance. Most hot A type main-sequence stars are metal-rich stars with log g from 3.5 to 4.5. The conclusions are reasonable within a certain error range. The theory of a gap area in the Hertzsprung–Russell diagram for stellar evolutions of medium mass stars is reflected in the statistical plots. The central core hydrogen burning stage and the central core helium burning stage correspond to the peak structures in the statistical plots for gravitational acceleration. The metal abundances among A, F, G and K type stars have a wide distribution. We cannot simply replace the metal abundances of these stars with the metal abundance of the Sun when doing fine research work.
X-ray irradiation measurements of the radiation tolerance of the ITkPixV1 ATLAS pixel readout chip
Authors: Mironova M. 
Published: February 2022

Abstract
The ITkPixV1 chip is the pre-production pixel readout chip for the Phase-2 Upgrade of the ATLAS experiment at the HL-LHC. The harsh environment of HL-LHC, including a peak luminosity of 5 × 1034 cm−1 s−1 and an estimated total ionising dose (TID) of around 1 Grad throughout its lifetime is placing strong requirements on the radiation tolerance of the chip. The radiation tolerance of the ITkPixV1 chip has been tested in irradiation campaigns using X-rays. The digital and analog front-end have been tested up to total doses of 1 Grad (at a dose rate of 4 Mrad/h) and show no significant operational issues.
Strength prediction of seawater sea sand concrete based on artificial neural network in python
Authors: Yu Hailing , Zheng Jianlan , Lin Qiujun 
Published: February 2022

Abstract
Based on the artificial neural network method, the nonlinear mapping between the 28d compressive strength of seawater sea sand concrete and concrete water-cement ratio, cement content, and the sand ratio was established in Python. The results showed that with reasonable network settings, the fitting of the model training was good, and the prediction results were satisfactory. The mean relative error of prediction results was 3.16%, and the correlation coefficient was 0.974. Therefore, it is possible to use an artificial neural network to set up a compressive strength prediction model for seawater sea sand concrete. Compared with the traditional mix design method, the artificial neural network design method can decrease the number of mixing proportion adjustments and reduce the waste of labor, time, and materials.
Development, Monte Carlo simulations and experimental evaluation of a 3D range-modulator for a complex target in scanned proton therapy

Published: February 2022

Abstract
The purpose of this work was to develop and manufacture a 3D range-modulator (3D RM) for a complex target contour for scanned proton therapy. The 3D RM is considered to be a viable technique for the very fast dose application in patient-specific tumors with only one fixed energy. The RM was developed based on a tumor from a patient CT and manufactured with high-quality 3D printing techniques with both polymer resin and aluminum. Monte Carlo simulations were utilized to investigate its modulating properties and the resulting dose distribution. Additionally, the simulation results were validated with measurements at the Marburg Ion-Beam Therapy Centre. For this purpose, a previously developed water phantom was used to conduct fast, automated high-resolution dose measurements. The results show a very good agreement between simulations and measurements and indicate that highly homogeneous dose distributions are possible. The delivered dose is conformed to the distal as well as to the proximal edge of the target. The 3D range-modulator concept combines a high degree of dose homogeneity and conformity, comparable to standard IMPT with very short irradiation times, promising clinically applicable dose distributions for lung and/or FLASH treatment, comparable and competitive to those from conventional irradiation techniques.
In-plane resonant excitation of quantum dots in a dual-mode photonic-crystal waveguide with high β-factor
Authors: Zhou Xiaoyan , Lodahl Peter , Midolo Leonardo 
Published: February 2022

Abstract
A high-quality quantum dot (QD) single-photon source is a key resource for quantum information processing. Exciting a QD emitter resonantly can greatly suppress decoherence processes and lead to highly indistinguishable single-photon generation. It has, however, remained a challenge to implement strict resonant excitation in a stable and scalable way, without compromising any of the key specs of the source (efficiency, purity, and indistinguishability). In this work, we propose a novel dual-mode photonic-crystal waveguide that realizes direct in-plane resonant excitation of the embedded QDs. The device relies on a two-mode waveguide design, which allows exploiting one mode for excitation of the QD and the other mode for collecting the emitted single photons with high efficiency. By proper engineering of the photonic bandstructure, we propose a design with single-photon collection efficiency of β > 0.95 together with a single-photon impurity of ϵ < 5 × 10−3 over a broad spectral and spatial range. The device has a compact footprint of
