Teaching Collaborative Practices: A Scoping Review of Preservice Interprofessional Education With a Focus on Preservice Speech-Language Pathologists and Preservice Teachers of Deaf and Hard of Hearing Students
Authors: Secora Kristen , Shahan Cheryl L. 
Published: April 2023

Purpose:
Speech-language pathologists (SLPs) and teachers of students who are deaf and hard of hearing (TODs) often work with the same students in a school setting to support their linguistic and educational needs. Previous research has extensively documented the importance of interprofessional practice and how educator and professional preparation programs have modified the curriculum to become more focused on collaboration. What is currently missing from the literature, however, is a discussion of the evidence-based methods used to teach preservice SLPs and TODs how to effectively collaborate together in support of Deaf and hard of hearing students.

Method:
We reviewed the literature related to interprofessional education (IPE) for preservice SLPs and preservice TODs across eight databases with a focus on the methods used to teach and develop interprofessional collaboration skills.

Results:
We located six relevant articles focused on IPE for preservice SLPs and TODs. Due to the limited number of studies, we expanded our search criteria to also include relevant studies that focused on IPE strategies from related fields.

Conclusions:
This review integrates research about best practices for educating preservice professionals in effective collaboration strategies to make evidence-based recommendations on implementing effective collaboration-focused IPE for preservice SLPs and TODs. Recommendations include joint classroom experiences, explicit instruction in critical skills and competencies for successful collaboration, modeling collaboration through co-teaching, and explicit instruction and practice in conflict management and perspective-taking.
Evaluation of the security performance of artificial noise‐aided STBC systems
Authors: Lee Hyein , Kim Sooyoung 
Published: April 2023

AbstractIn this paper, the security performance of artificial noise (AN)‐aided space time block coding (STBC) systems in wiretap channel is evaluated. The security performance is estimated in terms of the secrecy rate, which is defined as the difference of mutual information of the legitimate receiver and illegal eavesdropper. We derive a generalized secrecy rate formula for the system utilizing AN‐aided STBC, and also provide an expression for the approximated value with which the estimation time can be highly reduced. The simulation results reveal that the approximated formula well matches to the full estimation with a few orders of less complexity. In addition, it is proved that the maximum achievable secrecy rate for M‐ary modulation scheme approaches to bps/Hz when AN power is extremely high, showing perfect security protection at the expense of power efficiency.
Design of a trajectory contour controller for a dual‐axis precision motion stage based on improved iterative learning

Published: April 2023

AbstractTo solve the problem of contour error (CE) arising from the dual‐axis coupling of the X–Y coordinate planar motor stage under reciprocating motion conditions in integrated circuit (IC) manufacturing, the following two perspectives are considered: indirect intervention from a single‐axis servo tracking error (TE) control and direct intervention from a dual‐axis cross‐coupling control (CCC). An improved motion controller is designed using the iterative learning control (ILC) principle in conjunction with the motion characteristics of the dual‐axis mechanism. Specifically, the variable gain iterative learning controller with a variable forgetting factor (VFF‐VGILC) is designed to address the characteristics of single‐axis trajectory repetition and variable velocity planning in dual‐axis coupling. The significance of the VFF‐VGILC is to increase the servo control bandwidth of a single axis. On the other hand, the cross‐coupled iterative learning controller (CCILC) is designed on the dual‐axis cross‐coupling, while a pre‐compensation strategy is introduced in the CCC structure to form the pre‐CCILC. After experimental designing and testing are performed, the X–Y coordinate planar motor stage can effectively reduce the CE under various trajectory movements compared with the traditional controller. The trajectory curves drawn can meet the motion control requirements better and effectively enhance the motion control capability of the mechanism.

Published: April 2023

AbstractThe active power‐virtual frequency (P‐ω′) and reactive power‐virtual voltage (Q‐V′) droop control scheme has been suggested for coordinated control of distributed energy resources (DERs) in islanded microgrids. While this method mitigates the issue of active and reactive power coupling in the droop controller, its main limitation is power‐sharing error. Due to the local property of the virtual frequency and voltage, significant steady‐state errors occur for both active and reactive power sharing. In this paper, a decentralized method is proposed to eliminate the mentioned errors without utilization of communication links. In the proposed scheme, P‐ω′ and Q‐V′ droops are realized at the microgrid point of common coupling (PCC). By employing the PCC virtual frequency/voltage for the active/reactive power sharing of all DERs, the sharing errors caused by the local property are eliminated. Small signal stability of the proposed scheme is studied, and Hardware‐in‐the‐Loop (HIL) experimental results are presented to validate the proposed method and highlight the improvements compared with the conventional P‐ω′/Q‐V′ scheme. The results verify the efficacy of the proposed method for providing accurate active and reactive power sharing while regulating the frequency and voltage close to the rated values.

Published: April 2023

AbstractIn order to build UHV AC transmission lines at high altitudes, it is necessary to analyze the audible noise (AN) characteristics of the existing EHV transmission lines at high‐altitude areas to guide the design. The typical test data of AN for 750‐kV single‐circuit transmission lines measured at the Guanting long‐term observation station, located at an altitude of 1854 m, were collected. Two methods of sorting the test data of AN and extracting valid data were given. Then the levels of AN under different weather conditions were analyzed, which showed that AN was raised with the increase of instantaneous rainfall and snowfall. Typical frequency spectrums of AN under different weather were also obtained, the pure tone at 100 Hz was more prominent under rainy and snowy weather, and the pure‐tone oscillation attenuated at different positions. The statistical results and the calculated difference of AN over 5.5 h with continuous rainfall were obtained. For the 750‐kV transmission line in the quiet plateau areas, the calculated difference between AN during rainy days and fair weather can be taken as 25 dB, and the calculated value of the altitude correction coefficient of 2.85 dB/1000 m is better consistent with the measured value.

Published: April 2023

AbstractWith the development of the energy structure of the power system, the characterization of the observed oscillation in the power system has steadily evolved. With the increasingly high penetration of distributed energy sources and power electronic devices, such as the photovoltaic, wind power and charging pile, the basic mechanism, frequency ranges and propagation of oscillation would become more dynamic and complex. Therefore, the traditional parameter estimation, as well as the suppression methods would also suffer from dynamic oscillations. To this end, this paper first investigates the oscillation propagation and typical events caused by the oscillations. Next, the oscillation model estimation method including the model‐based and data‐driven based methods is discussed. The benefits and difficulties of various parameter estimate techniques are highlighted. Under this context, the validity and limitations of the current power system stability are summarized. Furthermore, the different oscillation damping and mitigation measures are compared, and the major adaptability and limitations are listed for the specific application scenarios. Conclusions are drawn, and the wideband oscillation becomes the future research objective where the future work is presented at the end of the paper.
Comparison of modified black-body fits for the estimation of dust optical depths in interstellar clouds
Authors: Juvela Mika 
Published: April 2023

Context. When dust far-infrared spectral energy distributions (SEDs) are fitted with a single modified black body (MBB), the optical depths tend to be underestimated. This is caused by temperature variations, and fits with several temperature components could lead to smaller errors.
Aims. We want to quantify the performance of the standard model of a single MBB in comparison with some multi-component models. We are interested in both the accuracy and computational cost.
Methods. We examine some cloud models relevant for interstellar medium studies. Synthetic spectra are fitted with a single MBB, a sum of several MBBs, and a sum of fxed spectral templates, but keeping the dust opacity spectral index fixed.
Results. When observations are used at their native resolution, the beam convolution becomes part of the fitting procedure. This increases the computational cost, but the analysis of large maps is still feasible with direct optimisation or even with Markov chain Monte Carlo methods. Compared to the single MBB fits, multi-component models can show significantly smaller systematic errors, at the cost of more statistical noise. The χ2 values of the fits are not a good indicator of the accuracy of the τ estimates, due to the potentially dominant role of the model errors. The single-MBB model also remains a valid alternative if combined with empirical corrections to reduce its bias.
Conclusions. It is technically feasible to fit multi-component models to maps of millions of pixels. However, the SED model and the priors need to be selected carefully, and the model errors can only be estimated by comparing alternative models.
Der Lichen planus des Ösophagus – Eine unterschätzte Erkrankung

Published: April 2023

ZusammenfassungEine Beteiligung des Ösophagus bei der Hauterkrankung Lichen planus wurde erstmals 1982 beschrieben und fast 30 Jahre lang als eine Rarität angesehen. Untersuchungen der letzten 10 Jahre aber zeigen, dass diese Erkrankung weniger selten ist als angenommen. Es ist sogar anzunehmen, dass der ösophageale Lichen planus (Esophageal Lichen planus, ELP) häufiger ist als die Eosinophile Ösophagitis (EoE). Die Ösophagusbeteiligung betrifft meist Frauen im mittleren Alter. Das Hauptsymptom ist eine Dysphagie. Endoskopisch erkennt man in der Speiseröhre eine charakteristische Schleimhautablösung, eine Trachealisierung, und gelegentlich Hyperkeratosen und bei langem Bestehen auch Stenosen. Wegweisend ist die Histologie mit einer subepithelialen Ablösung sowie einem bandförmigen Infiltrat aus T-Lymphozyten, dem Nachweis von apoptotischen Keratinozyten (Civatte Bodies) und Dyskeratosen. Die direkte Immunfluoreszenz zeigt Fibrinogen-Ablagerungen entlang der Basalmembran. Eine etablierte Therapie gibt es bisher nicht. Die Behandlung mit topischen Steroiden ist in 2/3 der Fälle wirksam. Eine Therapie wie beim klassischen Lichen planus scheint unwirksam zu sein. Bei symptomatischen Stenosen kann eine Dilatation indiziert sein. Der ELP reiht sich in die Gruppe der „neuen“ immunologisch vermittelten Erkrankungen des Ösophagus ein.

Abstract
Objectives Midline suprasellar meningiomas include planum sphenoidale, tuberculum sellae, and diaphragma sellae meningiomas. Multiple classifications have been previously documented; however, they come with controversies and limitations, including those with surgical implications. The aim of this study was to classify suprasellar meningiomas based on their behavior toward the underlying bone and neurovascular structures.
Methods Patients with newly diagnosed suprasellar meningiomas that underwent extended endoscopic transnasal approach between 2015 and 2021 were included in this study. The following parameters were evaluated: chiasmatic sulcus length, location of the optic chiasm and nerves, optic canal involvement, and vascular displacement.
Results We identified 40 cases of midline suprasellar meningiomas, 1 diaphragma sellae meningioma (type A), 10 tuberculum sellae meningiomas (type B), 9 chiasmatic sulcus meningiomas (type C), and 10 planum sphenoidale meningiomas (type D). Asymmetrical visual complaints were most common in chiasmatic sulcus meningiomas, followed by tuberculum sellae meningiomas (66 and 50%, respectively). Chiasmatic sulcus meningiomas showed increased separation between the optic chiasm and the A1/A2 complex (8.9 mm) compared with tuberculum sellae (2.7 mm) and planum sphenoidale (1.9 mm) meningiomas. Compared with other types, increased chiasmatic sulcus length was observed in chiasmatic sulcus meningiomas.
Conclusion Preoperative evaluation of bone involvement and tumor relation to neurovascular structures can be used to classify suprasellar meningiomas. Chiasmatic sulcus meningioma is a distinct subtype of suprasellar meningiomas. Its unique behavior toward nearby neurovascular structures could be of surgical value during tumor resection.

Published: April 2023

Objective This study aimed to examine the variation between clinician-recorded and continuously downloaded invasive blood pressure (BP).
Study Design Prospective study where invasive BP data were downloaded every 10 seconds for the first week of life. Hourly clinician-recorded BP was recorded. Agreement between the two methods were examined.
Results A total of 1,180 BP measurements were examined from 42 preterm infants with a mean (standard deviation [SD]) gestation and birthweight of 25.7 weeks (1.4) and 802 g (177) respectively. The mean (SD) bias was −0.11 mm Hg (3.17), but the 95% limits of agreement (LOA) varied between −6.3 and +6.1 mm Hg. Inotrope usage was significantly higher for BP measurements that fell in the 5% outliers when compared with those that fell within the 95% LOA (62.7 vs. 44.6%, p = 0.006).
Conclusion Clinicians showed no systematic bias to over- or underrecord BP, but some of the greatest differences were found in infants receiving inotropes.

Published: April 2023

Abstract
Background The additional donor site incisions in autologous breast reconstruction can predispose to abdominal complications. The purpose of this study is to delineate predictors of donor site morbidity following deep inferior epigastric perforator (DIEP) flap harvest and use those predictors to develop a machine learning model that can identify high-risk patients.
Methods This is a retrospective study of women who underwent DIEP flap reconstruction from 2011 to 2020. Donor site complications included abdominal wound dehiscence, necrosis, infection, seroma, hematoma, and hernia within 90 days postoperatively. Multivariate regression analysis was used to identify predictors for donor site complications. Variables found significant were used to construct machine learning models to predict donor site complications.
Results Of 258 patients, 39 patients (15%) developed abdominal donor site complications, which included 19 cases of dehiscence, 12 cases of partial necrosis, 27 cases of infection, and 6 cases of seroma. On univariate regression analysis, age (p = 0.026), body mass index (p = 0.003), mean flap weight (p = 0.006), and surgery time (p = 0.035) were predictors of donor site complications. On multivariate regression analysis, age (p = 0.025), body mass index (p = 0.010), and surgery duration (p = 0.048) remained significant. Radiographic features of obesity, such as abdominal wall thickness and total fascial diastasis, were not significant predictors of complications (p > 0.05). In our machine learning algorithm, the logistic regression model was the most accurate at predicting donor site complications with the accuracy of 82%, specificity of 0.93, and negative predictive value of 0.87.
Conclusion This study demonstrates that body mass index is superior to radiographic features of obesity in predicting donor site complications following DIEP flap harvest. Other predictors include older age and longer surgery duration. Our logistic regression machine learning model has the potential to quantify the risk of donor site complications.

Published: April 2023

AbstractPost-synthetic modification is a powerful technique allowing access to noncanonical peptide derivatives in a selective manner, but it has not so far been applied for the installation of multiple arrays of modified side chains. Here, we use this approach in solution phase to prepare short N- and C-capped homooligomers of 3-amino-1-methylazetidine-3-carboxylic acid with all the azetidine side chain functions in free amine form. The key step is the multiple reductive amination reaction of the corresponding post-synthetically deprotected secondary amines.

Authors: S. Prabakaran , K. Gowthame , R.B. Namasivaya Navin , A. Raghvi , S. Rajasekaran 
Published: April 2023

Objectives
The main aim of this study was to identify the evolving, early changes, premalignant and malignant lesions of larynx among smokers, and alcoholics by video laryngoscopy and to correlate the duration, frequency, and amount of smoking and alcohol with spectrum of symptoms presented and laryngeal morphology.

Material and Methods
This study was prospective study done on a total of 165 patients who attended the department of otorhinolaryngology, at a tertiary care center in South India with various ENT complaints. Patients who were above 18 years of age from both sexes and gave history of smoking and alcohol consumption were included in this study irrespective of their complaints. All these patients underwent video laryngoscopy, which helped in early diagnosing various laryngeal lesions and screening tool for development of laryngeal lesions. Following diagnosis, patients were treated accordingly with lifestyle modifications and abstinence from smoking and alcohol. The primary outcome measure is screening for laryngeal morphology and secondary outcome measures are identifiable laryngeal benign and malignant lesions among smokers and alcoholics who required appropriate treatment.

Results
There was a significant association between the type of lesion and age group, type of lesion and smoking, and type of lesion and alcohol when compared with nonsmokers and non-alcoholics. As the pack years and amount of alcohol consumption increased, there was a significant increase in the severity and association of lesions.

Conclusion
We were able to diagnose a large number of laryngeal lesions that helped in the early detection of premalignant and malignant lesions and their early treatment. The patients who were diagnosed with premalignant and malignant changes underwent microlaryngeal excision of the lesion and were in close follow-up to detect any recurrence.
The dynamic relationship between trade openness, foreign direct investment, capital formation, and industrial economic growth in China: new evidence from ARDL bounds testing approach
Authors: Hao Yuanyuan 
Published: April 2023

AbstractThe objective of this research is to use annual data from 1990 to 2021 to examine the long- and short-run dynamic relationships among China’s trade openness (TRO), foreign direct investment (FDI), capital formation (K), and industrial economic growth (IEG) using the Autoregressive Distribution Lag (ARDL) method. Firstly, the results of the ARDL co-integration tests show that there is a long-run co-integration relationship among TRO, FDI, K, and IEG. Secondly, from a path of influence perspective, both the long- and short-run relationships are almost the same. Specifically, TRO, FDI, and K all have positive effects on IEG and vice versa, which supports the feedback hypothesis. However, contrary to the short-run relationship, TRO and K have a small negative effect on IEG, but this is not statistically significant. Finally, K and TRO positively affect FDI, while FDI negatively affects K, although the effect is minimal and negligible at the 10% significance level. On the contrary, they are not statistically significant in the long run. These results support the theory that technological innovation in the trade, investment and capital system based on economic and market capital can stimulate the development of China’s industrial economy.
