Published: April 2021

PurposePhonological awareness (PA) requires the complex integration of language, speech, and auditory processing abilities. Enhanced pitch and rhythm discrimination have been shown to improve PA and speech-in-noise (SiN) discrimination. The screening of pitch and rhythm discrimination, if nonlinguistic correlates of these abilities, could contribute to screening procedures prior to diagnostic assessment. This research aimed to determine the association of PA abilities with pitch, rhythm, and SiN discrimination in children aged 5–7 years old.MethodForty-one participants' pitch, rhythm, and SiN discrimination and PA abilities were evaluated. To control for confounding factors, including biological and environmental risk exposure and gender differences, typically developing male children from high socioeconomic statuses were selected. Pearson correlation was used to identify associations between variables, and stepwise regression analysis was used to identify possible predictors of PA.ResultsCorrelations of medium strength were identified between PA and pitch, rhythm, and SiN discrimination. Pitch and diotic digit-in-noise discrimination formed the strongest regression model (adjustedR2= .4213,r= .649) for phoneme–grapheme correspondence.ConclusionsThe current study demonstrates predictive relationships between the complex auditory discrimination skills of pitch, rhythm, and diotic digit-in-noise recognition and foundational phonemic awareness and phonic skills in young males from high socioeconomic statuses. Pitch, rhythm, and digit-in-noise discrimination measures hold potential as screening measures for delays in phonemic awareness and phonic difficulties and as components of stimulation programs.
The Implementation of a Personalized Dynamic Approach for the Management of Prolonged Concussion Symptoms
Authors: Wright Jim , Sohlberg McKay Moore 
Published: April 2021

Purpose

This clinical focus article reviews the existing treatment literature on the management of prolonged concussion symptoms (PCS) for specifying treatment components that hold the most promise for effectively targeting functional goals that are disrupted due to cognitive impairments. Current evidence suggests the treatment ingredients of psychoeducation and cognitive strategy instruction can be effective for addressing changes in functioning due to perceived cognitive deficits in attention, working memory, and executive functioning. Based on the literature, we propose a personalized, dynamic approach to managing PCS that is tailored to the symptom profile of the individual client and consists of three phases,
treatment setup, implementation of treatment,
and
discharge plan,
in which the implementation phase consists of psychoeducation and strategy training. The unique aspect of this approach is the use of individualized status tracking measures on goal progress as well as strategy use and perceived strategy helpfulness to empirically guide treatment. Client performance directs clinical decisions, and the clinician adapts treatment components in order to facilitate functional change.

Conclusion
We provide a case example of an adolescent client treated in our university clinic to demonstrate the implementation of the proposed personalized and dynamic approach to PCS management.
Probing the temperature gradient in the core boundary layer of stars with gravito-inertial modes
Authors: Michielsen M. , Aerts C. , Bowman D. M. 
Published: April 2021

Aims. We investigated the thermal and chemical structure in the near-core region of stars with a convective core by means of gravito-inertial modes. We determined the probing power of different asteroseismic observables and fitting methodologies. We focus on the case of the B-type star KIC 7760680, rotating at a quarter of its critical rotation velocity.
Methods. We computed grids of 1D stellar structure and evolution models for two different prescriptions of the temperature gradient and mixing profile in the near-core region. We determined which of these prescriptions is preferred according to the prograde dipole modes detected in 4 yr Kepler photometry of KIC 7760680. We considered different sets of asteroseismic observables and compared the outcomes of the regression problem for a χ2 and a Mahalanobis distance merit function, where the latter takes into account realistic uncertainties for the theoretical predictions and the former does not.
Results. Period spacings of modes with consecutive radial order offer a better diagnostic than mode periods or mode frequencies for asteroseismic modelling of stars revealing only high-order gravito-inertial modes. We find KIC 7760680 to reveal a radiative temperature gradient in models with convective boundary mixing, but less complex models without such mixing are statistically preferred for this rotating star, revealing extremely low vertical envelope mixing.
Conclusions. Our results strongly suggest the use of measured individual period spacing values for modes of consecutive radial order as an asteroseismic diagnostic for stellar modelling of B-type pulsators with gravito-inertial modes.

We present the confirmation of a new sub-Neptune close to the transition between super-Earths and sub-Neptunes transiting the M2 dwarf TOI-269 (TIC 220 479 565, V = 14.4 mag, J = 10.9 mag, R⋆ = 0.40 R⊙, M⋆ = 0.39 M⊙, d = 57 pc). The exoplanet candidate has been identified in multiple TESS sectors, and validated with high-precision spectroscopy from HARPS and ground-based photometric follow-up from ExTrA and LCO-CTIO. We determined mass, radius, and bulk density of the exoplanet by jointly modeling both photometry and radial velocities with juliet. The transiting exoplanet has an orbital period of P = 3.6977104 ± 0.0000037 days, a radius of 2.77 ± 0.12 R⊕, and a mass of 8.8 ± 1.4 M⊕. Since TOI-269 b lies among the best targets of its category for atmospheric characterization, it would be interesting to probe the atmosphere of this exoplanet with transmission spectroscopy in order to compare it to other sub-Neptunes. With an eccentricity e = 0.425−0.086+0.082, TOI-269 b has one of the highest eccentricities of the exoplanets with periods less than 10 days. The star being likely a few Gyr old, this system does not appear to be dynamically young. We surmise TOI-269 b may have acquired its high eccentricity as it migrated inward through planet-planet interactions.

Context. Models of stellar structure and evolution can be constrained using accurate measurements of the parameters of eclipsing binary members of open clusters. Multiple binary stars provide the means to tighten the constraints and, in turn, to improve the precision and accuracy of the age estimate of the host cluster. In the previous two papers of this series, we have demonstrated the use of measurements of multiple eclipsing binaries in the old open cluster NGC 6791 to set tighter constraints on the properties of stellar models than was previously possible, thereby improving both the accuracy and precision of the cluster age.
Aims. We identify and measure the properties of a non-eclipsing cluster member, V56, in NGC 6791 and demonstrate how this provides additional model constraints that support and strengthen our previous findings.
Methods. We analyse multi-epoch spectra of V56 from FLAMES in conjunction with the existing photometry and measurements of eclipsing binaries in NGC6971.
Results. The parameters of the V56 components are found to be Mp = 1.103 ± 0.008 M⊙ and Ms = 0.974 ± 0.007 M⊙, Rp = 1.764 ± 0.099 R⊙ and Rs = 1.045 ± 0.057 R⊙, Teff,p = 5447 ± 125 K and Teff,s = 5552 ± 125 K, and surface [Fe/H] = +0.29 ± 0.06 assuming that they have the same abundance.
Conclusions. The derived properties strengthen our previous best estimate of the cluster age of 8.3 ± 0.3 Gyr and the mass of stars on the lower red giant branch (RGB), which is MRGB = 1.15 ± 0.02 M⊙ for NGC 6791. These numbers therefore continue to serve as verification points for other methods of age and mass measures, such as asteroseismology.
Is Valgus Cut Angle Based on Radiographic Measurements in Total Knee Arthroplasty Really Inaccurate? A Comparison of Two- and Three-Dimensional Measurements
Authors: Liu LiMing , Lei Kai , Chen Xin , Fan HuaQuan , Yang Liu , Guo Lin 
Published: April 2021

AbstractRadiographs are widely used to measure distal femoral valgus cut angle (VCA) in total knee arthroplasty (TKA), but its accuracy is controversial. This study used three-dimensional (3D) reconstruction models to verify the accuracy of VCA measurements on radiographs, and explore the correlation of VCA with hip–knee–ankle (HKA) angle and lateral femoral bowing angle (FBA). A total of 444 osteoarthritis knees of 444 patients from August 2016 to June 2018 was included retrospectively. On radiographs, two-dimensional VCA (VCA-2D) was measured between the femoral mechanical axis and the distal femoral anatomical axis, and HKA was measured between the femoral mechanical axis and the tibial mechanical axis. On the coronal projection of computed tomography 3D models, the anatomical landmarks used for VCA-3D measurements were the same as those on the radiographs, FBA was measured between the proximal and distal femoral anatomical axis. The distributions of VCA-2D and VCA-3D were evaluated by means and variances. The correlation between HKA and VCA and between FBA and VCA was explored. There was a statistical difference between VCA-2D and VCA-3D (p < 0.001), but the deviation was very small (0.15 ± 0.69 degrees), 83.3% of the deviations were less than 1 degree. VCA would increase both in 2D and 3D with increasing of FBA and HKA varus. There was no statistically significant difference between VCA-2D and VCA-3D in patients with moderate varus knees (0–8 degrees of varus) and mild bowing femurs (FBA <5 degrees). Overall, the deviation caused by using radiography to measure VCA was negligible. VCA measurements using radiographs were accurate in patients with moderate varus knees and mildly bowed femurs. This study reflects level of evidence III.
A Cadaveric Anatomical Study of the Relationship between Proximal Tibial Slope and Coronal Plane Deformity
Authors: Foos Julia , Amakoutou Kouami , Cooperman Daniel R. , Liu Raymond W. 
Published: April 2021

AbstractMedial proximal tibial angle (MPTA) and posterior proximal tibial angle (PPTA) are commonly used to characterize the geometry of proximal tibia and are important considerations in lower extremity realignment procedures and total knee arthroplasty. This study utilized a large cadaveric collection to explore relationships between tibial slope and coronal plane deformity of the tibia. We utilized 462 well-preserved skeletons (924 tibiae), excluding any with fracture or obvious rheumatologic or infectious findings. Custom cards were made with different sized arcs on the bottom surface, so that they could rest on the anterior and posterior aspects of the medial and lateral tibial plateaus of each bone to measure PPTA. Previously measured MPTA values for the same bones were also utilized. Multiple regression analysis was used to determine relationship between MPTA and medial and lateral PPTAs. The mean age was 56 ± 10 years, with 13% female and 31% African American (remainder Caucasian). The mean MPTA was 87.2 ± 2.4 degrees. The mean medial plateau PPTA was 81.5 ± 3.8 degrees and mean lateral plateau PPTA was 81.3 ± 3.7 degrees. Regression analysis found that MPTA was significantly associated with both medial and lateral PPTAs (standardized betas 0.197 and 0.146, respectively, p < 0.0005 for both). There was a significant correlation between lateral and medial PPTAs (r = 0.435, p = 0.03). The clinical significance of these findings warrants further investigation and emphasizes the importance of carefully assessing the sagittal plane when planning reconstruction of a tibia with varus or valgus deformity, particularly high tibial osteotomies.

Abstract
Background Poor comprehension and low compliance with post-ED (emergency department) care plans increase the risk of unscheduled ED return visits and adverse outcomes. Despite the growth of personal health records to support transitions of care, technological innovation's focus on the ED discharge process has been limited. Recent literature suggests that digital communication incorporated into post-ED care can improve patient satisfaction and care quality.
Objectives We evaluated the feasibility of utilizing MyEDCare, a text message and smartphone-based electronic ED discharge process at two urban EDs.
Methods MyEDCare sends text messages to patients' smartphones at the time of discharge, containing a hyperlink to a Health Insurance Portability and Accountability Act (HIPAA)-compliant website, to deliver patient-specific ED discharge instructions. Content includes information on therapeutics, new medications, outpatient care scheduling, return precautions, as well as results of laboratory and radiological diagnostic testing performed in the ED. Three text messages are sent to patients: at the time of ED discharge with the nurse assistance for initial access of content, as well as 2 and 29 days after ED discharge. MyEDCare was piloted in a 9-month pilot period in 2019 at two urban EDs in an academic medical center. We evaluated ED return visits, ED staff satisfaction, and patient satisfaction using ED Consumer Assessment of Healthcare Providers and Systems (ED-CAHPS) patient satisfaction scores.
Results MyEDCare enrolled 27,713 patients discharged from the two EDs, accounting for 43% of treat-and-release ED patients. Of the treat-and-release patients, 27% completed MyEDCare discharge process, accessing the online content at the time of ED discharge. Patients discharged via MyEDCare had fewer 72-hour, 9-day, and 30-day unscheduled return ED visits and reported higher satisfaction related to nursing care.
Conclusion EDs and urgent care facilities may consider developing a HIPAA-compliant, text message, and smartphone-based discharge process, including the transmission of test results, to improve patient-centered outcomes.

Authors: Zhao Lijuan , Liang Ruoyu , Xu Zhiniu , Zhao Haiying 
Published: April 2021

Abstract
In this paper, a new photonic crystal fiber (PCF) for long-distance transmission of orbital angular momentum (OAM) is proposed. The rectangular air holes are distributed in the cladding and a circular air hole is distributed in the core. The designed PCF can support 88 OAM modes over S + C + L + U wavelength band. The characteristics of the PCF are analyzed by using the finite element method systematically. The results show that the nonlinear coefficient is lower than 2.8 km−1·W−1 over S + C + L + U wavelength band, and the minimum value is as low as 0.9 km−1·W−1. The confinement loss of each mode is between 10−17–10−10 dB·m−1, and the stable transmission distance of the OAM modes is up to 60 km. Additionally, the effective mode filed area and dispersion of the PCF are also analyzed. In general, the PCF can be used in modular division multiplexing which can effectively improve the capacity and transmission distance of communication system.
An overview on Lithium-ion batteries recycling processes
Authors: Hu Qiushi , Xu Linghong 
Published: April 2021

Abstract
In the last few decades, well-developed lithium-ion batteries (LIB) with high capacity showed great performance in electric vehicles. However, efforts must be made in the field of LIB recycling to reduce the negative effects caused by spent LIB on the environment. The processes for lithium-ion batteries recycling are presented through three different portions includeing pre-treatment, secondary treatment and further treatment. In pre-treatment, the LIB is firstly discharged and disassembled manually. Secondly, the unit cells are shattered and separated into black mass mainly by physical properties through secondary treatment. Lastly, the black mass is decomposed into raw materials for recovery or resynthesizing in further treatment. Interdisciplinary approaches and secondary use feasibility are also discussed for future application prospect.

Published: April 2021

Abstract
Bimetallic nanostructures are interesting materials for many applications ranging from plasmonics to catalysis. However, synthesizing bimetallic nanorods with good control over composition, morphology and maintaining an anisotropic shape is challenging. Here, we have shown a reproducible approach to the synthesize the bimetallic core-shell nanorods within a stabilizing mesoporous silica shell and with an Au core and a Pd metal shell with excellent control over their properties. Specifically, we demonstrate that the thickness and morphology of the Pd metal shell (rough/smooth) can be precisely tuned and studied the plasmonic properties of the resulting bimetallic nanostructures in detail. Our approach can be naturally extended to different or more than two metals leading to rod-shaped metal particles with highly tunable materials properties that are of interest in their use in optical and catalytic applications.
Effect of ZnO on dielectric properties of Li-Al-Si photoetchable glasses as an interposer
Authors: Liang Tianpeng , Zhang Jihua 
Published: April 2021

Abstract
In current three-dimensional (3D) radio frequency (RF) package field, the silicon interposer can’t entirely meet the needs of the package because of its non-negligible dielectric loss. Similarly, the application of through Glass vias (TGV) has restriction for the same reason. Therefore, this paper focuses on reducing dielectric loss of photoetchable glass (PEG), as well as the performance of TGV technology of PEG for packaging. The PEG was reduced in the dielectric loss by the addition of ZnO. The reduction in dielectric loss is due to changes in structure. The structure of PEG was analyzed through the XRD and the Raman spectroscopy. The dielectric performance was verified by the Impedance Analyzer. The result indicated dielectric loss obviously decreased to 0.0035 by ZnO doped and the reason primarily attributed to the decrease number of the Non-Oxygen-Bridge in the glass network and the structure is more stable. Through thermal processes and etching, the average diameter obtained around 75μm by TGV, and the aperture ratio of up to 25: 1, TGV density can reach 10000 / cm2.

Published: April 2021

Abstract
In order to achieve the demand for improving the wear resistance of titanium alloy surfaces, a combination of magnetron sputtering (PVD), chemical vapor deposition (CVD) and thermal vulcanization methods is used to prepare highly wear-resistant WS2/W Composite coating on the surface of TC4 titanium alloy. Scanning electron microscope (SEM), X-ray diffractometer (XRD) and X-ray energy dispersive spectrometer (EDS) were used to characterize the micro-morphology, microstructure and chemical composition of the composite coating. The micro-hardness and wear resistance of the composite coating were tested. The results show that the thickness of each layer of the WS2/W composite coating prepared by the experiment is about 16μm and 60μm respectively, the coating structure is dense, and the interface between the layers is obvious. The average micro-hardness of WS2 layer and W layer are 110.4HV and 740.1HV respectively. The surface friction factor of WS2/W composite coating is 0.15, which is about 18% of the matrix (0.85). The wear rate is 1.184 × 10-6mm3·mm-1, which is about 45% of the substrate (1.628 × 10-6mm3·mm-1), which has better wear resistance and anti-friction characteristics.
