A Survey of Speech-Language Pathologists' and Teachers' Perceptions of Collaborative Service Delivery
Authors: Brimo Danielle , Huffman Hannah Elizabeth 
Published: March 2023

Purpose:
The purpose of this study was to compare speech-language pathologists' (SLPs) and teachers' perceptions of collaborative service delivery in a school setting.

Method:
We created a survey for SLPs and teachers that included demographic questions and questions about the use of collaborative service delivery models, identification of collaborative partners, and perceived barriers to collaboration. Eighty-seven SLPs and 77 teachers responded to the survey from 28 states. We analyzed the data using mixed methods.

Results:
The majority of SLPs reported that they used a combination of collaborative and noncollaborative service delivery models. Teachers also reported that the SLP at their school used collaborative and noncollaborative service delivery models. When asked to report on their collaboration experience generally, teachers rated their experience with collaboration more positively than SLPs. Teachers also were not as likely to identify SLPs as collaborative partners when compared with SLPs who identified teachers as collaborative partners. Finally, teachers and SLPs reported similar barriers to implementing a collaborative service delivery model. However, SLPs identified roles and responsibilities and training on collaboration as barriers to collaboration more than teachers.

Conclusions:
This study compared SLPs' and teachers' perceptions of collaborative service delivery in schools. The similarities and differences between SLPs and teachers can be used to help facilitate change in the use of collaborative service delivery models.
A combined cyclic stabilizing switching law for continuous time positive switched systems
Authors: Zheng Yan , Lin Xuefei , Wang Yaonan 
Published: March 2023

AbstractBased on a linear copositive Lyapunov function (LF), a combined cyclic stabilizing switching law with one stage being classified into four cases is proposed for continuous time positive switched systems composed of two unstable subsystems. Under the combined cyclic stabilizing switching law, the positive switched system is asymptotically stable and robust against certain class of perturbations. Finally, simulation verifies the effectiveness of the proposed switching law.

Published: March 2023

AbstractThe need for a high‐frequency and high‐efficiency gallium nitride (GaN)‐based buck converter that can be controlled directly by a low swing pulse width‐modulated (PWM) signal, without the need for additional buffers or preamplifiers, poses a significant challenge in the field of power conversion and dynamically power supply applications. To solve this problem, this letter presents a monolithic two‐phase synchronous buck converter, fabricated using a 0.25‐um GaN‐on‐Si process, integrated both the drivers and power stage transistors, without requiring additional buffers or preamplifiers. So, the proposed converter can be directly controlled by a PWM signal with a swing of only 1 V (−0.5 to 0.5 V). At a 100‐MHz switching frequency, the converter achieves a maximum output power of 12 W with a power stage efficiency of 82%. The converter includes two identical half‐bridge Monolithic Microwave Integrated Circuit (MMICs), and with the frequency multiplication property of multi‐phase topology, the equivalent switching frequency can reach 200 MHz in the open‐loop operating mode. The experimental results show that the converter can track a 40‐MHz bandwidth envelope signal (256 QAM, 6 dB PAPR) with 80.1% efficiency.

Published: March 2023

AbstractCurrently, in multitrain DC subway system, abnormal increase of rail potential (RP) and stray current (SC) has seriously threatened the safe operation of the system. Over voltage protection device (OVPD) is generally chosen to control the RP, but its action process may increase the amplitude of SC seriously. Here, the grounding resistance of OVPD is optimized by a proposed multi‐objective decomposition algorithm based on differential evolution (MOEA/D‐DE) to suppress the rise of RP and SC synergistically. Firstly, the simulation model of the DC subway system with multitrain is built, the power flow calculation is conducted, and the dynamic RP and leakage current (LC) at the location of traction substation are obtained. Secondly, the double objective optimization model of maximum RP and LC is established and solved by MOEA/D‐DE. Finally, the effectiveness of the proposed method is verified based on the data of Guangzhou Metro Line 2. Results show that the SC of the system can be controlled effectively with OVPD grounding mode after optimization, and integrated control of RP and SC can be accomplished.
A validation study of a fixed‐based, medium fidelity driving simulator for human–machine interfaces visual distraction testing

Published: March 2023

AbstractStudies comparing results captured in a simulator with those on road are important to validate the approach but are scarce in the context of secondary task distraction due to the potential ramifications of diverting attention away from safe driving. The authors compare distraction‐related data from two studies exploring human–machine interfaces (HMI) design: one conducted in a static, medium‐fidelity driving simulator with a vehicle enclosure and immersive visual environment, and one conducted on road. In both, 19 drivers undertook an identical selection of touchscreen, point‐and‐select tasks. The magnitude of visual distraction (defined as off‐road glances directed towards the touchscreen) differed between the road and the simulator, with drivers making more and longer off‐road glances when interacting with the interface on road. However, the ordering of effects in response to changes to the complexity of interface design was the same. For example, the number and duration of off‐road glances increased with increasing number of interface elements, and smaller targets attracted longer off‐road glances, in both the road and simulator studies. The work demonstrates good relative validity for the use of medium‐fidelity driving simulators for HMI‐visual distraction testing, supporting their application in this context, and adds to the literature regarding the visual demand characteristics of in‐vehicle interfaces.
Frequency‐tunable resonant hybrid vibration energy harvester using a piezoelectric cantilever with electret‐based electrostatic coupling

Published: March 2023

AbstractHybrid vibration energy harvesting technology converts vibration energy into electricity using multiple transduction mechanisms to improve output power. A frequency‐tunable resonant hybrid vibration energy harvester using a piezoelectric cantilever with electret‐based electrostatic coupling is proposed in this article. The electrostatic coupling including electrostatic force coupling and electrical damping coupling is introduced by an electret film placed below the cantilever, where the electrostatic force acting on the cantilever realises a tunable resonant frequency and additional electrical damping boosts power output. A coupling electromechanical model is derived using Euler–Bernoulli beam theory and Kirchhoff's law. By investigating the static and dynamic stability of cantilever, the maximum electret surface potential is defined to prevent the pull‐in phenomenon. The damping of the device is evaluated, and the optimal electret surface potential is determined to obtain the matching of the electrical and mechanical damping for maximum power output. The resonant frequency of hybrid vibration energy harvester can be adjusted in range of 176.1 rad/s by changing the electret surface potential and resistive load. The experimental output power of hybrid vibration energy harvester was 5.2 μW, 27.4 times higher than that of the individual piezoelectric generator. The proposed hybrid vibration energy harvester exhibits a promising potential to power microelectronic devices and wireless sensor network node.

Abstract
Background Arterial compression of the trigeminal nerve at the root entry zone has been the long-attributed cause of compressive trigeminal neuralgia despite numerous studies reporting distal and/or venous compression. The impact of compression type on patient outcomes has not been fully elucidated.
Objective We categorized vascular compression (VC) based on vessel and location of compression to correlate pain outcomes based on compression type.
Methods A retrospective video review of 217 patients undergoing endoscopic microvascular decompression for trigeminal neuralgia categorizing VC into five distinct types, proximal arterial compression (VC1), proximal venous compression (VC2), distal arterial compression (VC3), distal venous compression (VC4), and no VC (VC5). VC type was correlated with postoperative pain outcomes at 1 month (n = 179) and last follow-up (mean = 42.9 mo, n = 134).
Results At 1 month and longest follow-up, respectively, pain was rated as “much improved” or “very much improved” in 89 69% of patients with VC1, 86.6 and 62.5% of patients with VC2, 100 and 87.5% of patients with VC3, 83 and 62.5% of patients with VC4, and 100 and 100% of patients with VC5. Multivariate analysis demonstrated VC4 as a significant negative of predictor pain outcomes at 1 month, but not longest follow-up, and advanced age as a significant positive predictor.
Conclusion The degree of clinical improvement in all types of VC was excellent, but at longest follow-up VC type was not a significant predictor out outcome. However distal venous compression was significantly associated with worse outcomes at 1 month.
Embryology and Clinical Development of the Human Olfactory System
Authors: Sarnat Harvey B. , Flores-Sarnat Laura 
Published: March 2023

AbstractThe olfactory system is unique as a special sensory system in its developmental neuroanatomy and function. Neonatal olfactory reflexes can be detected in the fetus from 30 weeks gestation and can be tested in term and preterm neonates and older children. Most efferent axons from the olfactory bulb terminate in the anterior olfactory nucleus within the olfactory tract, with secondary projections to the amygdala, hypothalamus, hippocampus, and entorhinal cortex (parahippocampal gyrus), with tertiary projections also to the insula and other cortical regions. The olfactory bulb and tract incorporate an intrinsic thalamic equivalent. The olfactory bulb may be primary in generating olfactory auras in some cases of temporal lobe epilepsy. Developmental malformations may involve the olfactory bulb and tract, isolated or as part of complex cerebral malformations and genetic syndromes. Primary neural tumors may arise in the olfactory bulb or nerve. Impaired olfaction occurs in neonatal hypoxic/ischemic and some metabolic encephalopathies. Loss of sense of smell are early symptoms in some neurodegenerative diseases and in some viral respiratory diseases including coronavirus disease 2019. Testing cranial nerve I is easy and reliable at all ages, and is recommended in selected neonates with suspected brain malformations or encephalopathy.
Relationship between Initial Lactate Level with Mortality in Children with Sepsis and Septic Shock: A Comparison with the PRISM-3 Score
Authors: Başargan Göksu , Argun Mustafa , Samsa Hasan 
Published: March 2023

AbstractObjective Sepsis and septic shock are leading causes of mortality and morbidity in intensive care units. Our study aimed to compare the pediatric risk of mortality (PRISM-3) score, which is used for predicting mortality risk among critically ill patients in pediatric intensive care units, with laboratory parameters, particularly lactate parameters.Methods This study included 38 patients aged 1 month to 18 years who were managed for sepsis and septic shock in a pediatric intensive care unit. Lactate, D-dimer, troponin T, and N-terminal prohormone of brain natriuretic peptide levels were measured at the 0th and 24th hours. The patients were divided into survivors and nonsurvivors and those with septic shock and those without.Results There were a total of 38 patients with a median age of 12 months, of whom 17 (44.7%) were males and 21 (55.3%) were females. Six (15.8%) patients died within 7 days after the diagnosis. Nonsurvivors had significantly higher median values of PRISM-3 (p = 0.002), C-reactive protein (p = 0.046), and partial arterial carbon dioxide pressure (p = 0.041). PRISM-3 showed a good discriminatory power (area under the curve [AUROC] = 0.878; p < 0.0001) and baseline lactate level showed a moderate level of discriminatory power (AUROC = 0.734 p = 0.0254) for early mortality within 7 days.Conclusion PRISM-3 and baseline lactate predict early mortality in children with sepsis and septic shock. We suggest that adding lactate, which is not included in the PRISM-3 score, to the score may increase the score's predictive ability for mortality. We believe, however, that randomized, controlled, multicenter studies with larger sample sizes should be conducted to test this hypothesis.

Authors: Hai Pham Nhu , Son Tong Minh , Anh Nguyen Viet , Ngoc Vo Truong Nhu , Tra Nguyen Thu 
Published: March 2023

Abstract
Objectives Provisional crowns play an integral role in prosthodontic therapy and need to be fabricated with high accuracy to ensure good marginal fit and proper contour. The aim of this study is to evaluate the effect of 3D printer's horizontal pixel resolution on trueness of the intaglio surface, external surface, and marginal area and the actual marginal adaptation of the interim crowns.
Materials and Methods A gypsum reference model of mandible with a prepared right first molar was scanned with a dental laboratory scanner (AutoScan-DS-MIX, Shining 3D) and a digital provisional crown was design using the computer-aided design (CAD) software (Exocad). The provisional crown was manufactured by two printers with different horizontal resolutions (Sonic Mini 4K Printer and Sonic Mini 8K Printer). The printed crowns were scanned using the aforementioned scanner. The trueness of the external surface, internal surface, and marginal area of the provisional crowns was evaluated by comparing the scanned data with the reference CAD design data using a 3D inspection software (Geomagic Control X, 3D systems). The trueness of the crown manufactured by two printers was compared by a two-sided test (α = 0.05). Finally, the marginal adaptation of the provisional crowns was evaluated on the printed removable dies and compared.
Results The results revealed that there was a significant difference in the trueness of the marginal area and the marginal adaptation (p < 0.05).
Conclusions It can be concluded that the trueness of provisional crown marginal area and the marginal adaptation was affected by the horizontal resolution of the 3D printer.
Translating explicatures between Arabic and English
Authors: Jarrah Marwan , Al-Jarrah Rasheed 
Published: March 2023

AbstractThis article explores which areas of explicature identification (i.e., disambiguation, reference resolution, saturation, free enrichment, and ad hoc concept constructions) were more attended to in Arabic-English translation. Twenty translators were asked to render from one language into another 50 sentences whose logical form could be enriched by explicatures. Translators were found to attend more to the effects of disambiguation and reference resolution. A demarcation line was drawn between explicatures that called for completing overt logical forms (disambiguation and reference resolution) and those that prompted calculating pragmatic competence and meta-linguistic knowledge (saturation, free enrichment, and ad hoc concept constructions). Using relevance theory as a framework of analysis, we propose that completing overt logical forms is more rewarding and less costly for translators than computing pragmatic competence and meta-linguistic knowledge. The figures corroborated this assumption, which showed that explicature observance was positively correlated with educational attainment and years of experience.
Teachers’ codeswitching in L2 Chinese classes
Authors: Li Fang , Yiakoumetti Androula 
Published: March 2023

Abstract
The study deals with the sociolinguistic phenomenon of codeswitching as manifested in community-based
ethnic-language classes. More specifically, it focuses on teachers’ codeswitching from students’ second language (Mandarin
Chinese) to students’ first language (English). The empirical study was conducted at one Chinese community school in the United
Kingdom to investigate the instances in which teachers switch to students’ first language and to explore teachers’ introspection
regarding their codeswitching behavior. Twelve types of codeswitching were identified and categorized in accordance with functions
recorded in other studies. Discrepancies between teachers’ beliefs on the choice of language medium and their actual practices
were found. Teachers were not always aware of their codeswitching and they generally held positive attitudes towards their
conscious codeswitching and negative attitudes towards subconscious codeswitching. Conscious switches were used mainly for
pedagogical, interpersonal, and interactive purposes. A sense of guilt was found to be associated with their unconscious
codeswitching. This study suggests that raising teachers’ awareness of the potential usefulness of codeswitching within
ethnic-language education is paramount.
The construction of Chinese pedagogical grammar system
Authors: Li Nini 
Published: March 2023

Abstract
This paper explores two sets of criteria used to construct pedagogical grammar systems both in English and Chinese. Larsen-Freeman (2001, 2014) built a three-dimensional grammar framework to guide English teachers in constructing an approach to teaching grammar. The three dimensions are grammatical structures (morphosyntactic form), meaning (semantics; it can be lexical or grammatical) and appropriate use in context (pragmatics). Feng and Shi (2011, 2015) proposed a new model of teaching and learning Chinese called Trinitarian Grammar, consisting of three parts: the structure of sentences, the function of the structure and the contexts of the structure and the function used in Mandarin Chinese. This paper, however, suggests a four-dimensional framework for Chinese pedagogical grammar: grammatical structure, meaning (including lexical and grammatical meaning), pragmatic function and a sequence of typical contexts starting with an “optimal understanding model (OUM)”.
Ritual and modern “politeness” in the Romanian Principalities during the Phanariot period
Authors: Constantinescu Mihaela-Viorica 
Published: March 2023

AbstractThe paper focusses on ritual “politeness” in the eighteenth- and early-nineteenth century Romanian Principalities of Wallachia and Moldavia from a historical sociopragmatic perspective. The analysis of ceremonial literature and memoirs aims to highlight the instrumental role that the performance of conventional gestures and the use of conventional formulae have in presenting the self/other image. The period under consideration attests to the prominence of the Ottoman cultural model in the Romanian Principalities; nevertheless, the conduct prompted by Western and Central European culture was also rapidly emerging in these borderlands at the same time. When Romanian participants shift their behaviour in intercultural interactions according to the Eastern or Western norms, the choices they make have profound implications (political, social, and cultural).
Creole and power
Authors: Westphal Michael , Wilson Guyanne 
Published: March 2023

Abstract
The paper presents a Critical Discourse Analysis of Jamaican and Trinidadian legal-cross examinations, using data from the International Corpus of English. Although English is the dominant language of the courtroom, the analysis shows that Creole is used by both attorneys and witnesses. In contrast to previous associations of Creole with powerlessness and Standard English with power, attorneys make use of both varieties to exert their authority in the courtroom. Hence, the value of specific linguistic resources and who can use them for which purpose depends on the speakers’ social and institutional positionality. On a methodological level, the paper demonstrates that the International Corpus of English provides valuable data for critical qualitative analyses of language variation in New Englishes.
Question intonation patterns in Nigerian English
Authors: Oyebola Folajimi , Melles Warsa 
Published: March 2023

Abstract
This study investigates the intonation patterns in wh-questions and yes/no-questions used by educated Nigerian speakers of English. It examines the possible influence of gender, ethnicity, and question type on the prosodic marking of questions. Audio recordings taken from the Nigerian component of the International Corpus of English were annotated in Praat using the tones and breaks indices transcription convention. The results show that there are similar intonation patterns among Nigerian speakers. Both wh-questions and yes/no-questions tend to start with a level tone; while wh-questions end mostly with a falling tone, yes/no-questions end either with a falling or a rising tone. The results demonstrate that whereas gender has no significant effect, both ethnicity and question type significantly influence intonation patterns.
Effect of Orbital Characteristic of Inclined Third-body on Motion of Secondary-body for a Hierarchical Triple Systems
Authors: Bakhtiari Majid 
Published: March 2023

Abstract
The influence of a third-body’s orbital elements on the second-body’s motion in a hierarchical triple system is a crucial problem in astrophysics. Most prolonged evaluation studies have focused on a distant zero-inclined third-body. This study presents a new perspective on second-body motion equations that addresses a perturbing-body in an elliptic orbit derived with consideration of the axial-tilt (obliquity) of the primary. The proposed model is compared by the dual-averaged method and the N-body problem algorithm. After validation, a generalized three-body model is derived to investigate the effects of the third-body’s orbital elements on secondary-body motion behavior. The proposed model considers short-time oscillations that affect secular evaluation and applies to exoplanets with all the primary and third body eccentricities, inclinations, and mass ratios. It is shown that the obliquity of the primary (or third-body’s inclination) must be considered for precise long-term assessment, even in highly-hierarchical systems.
Manipulator Motion Planning Based on Improved RRT Algorithm
Authors: Song Qisong , Li Shaobo , Pu Ruiqiang 
Published: March 2023

Abstract
Aiming at the problems that the Rapidly-exploring Random Tree (RRT) algorithm has more time-consuming and longer paths in the manipulator motion planning, we propose an improved RRT algorithm based on probabilistic target bias strategy and triangular inequality pruning method. This paper simulates the algorithm from three dynamic environments with different numbers of obstacles. The simulation results show that the proposed improved RRT algorithm can plan a shorter path in less time.
