Expanding the Clinical Toolset: Acoustic Analyses for Speech-Language Pathologists and Audiologists in the 21st Century
Authors: Bunta Ferenc , Gósy Mária 
Published: November 2022

Purpose:
Clinical practice in audiology and speech-language pathology in the 21st century could greatly benefit from incorporating acoustic analyses because they can enhance and augment more traditional measures used when assessing communication disorders. However, more than 2 decades into our new millennium, acoustic analyses have not become widely used in clinical practice despite the fact that such analyses are free, widely available, and easy to use. More importantly, they hold unique advantages that could greatly benefit service delivery by speech-language pathologists and audiologists. In this clinical focus article, we aim to (a) present the utility and the benefits of using acoustic analyses in clinical practice, (b) illustrate those benefits with specific examples, and (c) encourage clinicians to take advantage of the unique contributions that acoustic analyses of speech may offer above and beyond traditional evaluations.

Conclusions:
The significant number of publications on clinical populations in communication disorders that include acoustic analyses testifies to the utility and necessity of such analyses for practicing audiologists and speech-language pathologists. We demonstrate the use of acoustic analyses with examples that range from aphasia to speech sound disorders, and we aim to demonstrate how acoustic analyses of speech can be a valued supplement to more traditional clinical evaluations.

Authors: Di Pasquale Valentina , De Simone Valentina , Giubileo Valeria , Miranda Salvatore 
Published: November 2022

AbstractThe occurrence of human errors significantly affects the performance and economic results of production systems. In this context, Human Reliability Analysis (HRA) methods play a key role in assessing the reliability of a man–machine system. Several HRA methods use Performance‐Shaping Factors (PSFs), that is, all the aspects of human behaviour and environment that can affect human performance, to evaluate the Human Error Probability (HEP). However, despite the greater emphasis given by researchers to define of PSFs in recent years, the changes caused by the new enabling technologies implemented in manufacturing systems and derived from the Industry 4.0 paradigm have not yet been fully explored. Focussing on Human–Robot Collaboration (HRC) in production systems, the authors aim to define a PSF taxonomy that is useful for HEP evaluations in collaborative environments. To the best of the authors' knowledge, HRA approaches have not been investigated yet for HRC applications. The proposed taxonomy, which results from the integration of the most significant factors impacting workers' performance in HRC into the PSFs provided by an HRA method, can represent an important contribution for researchers and practitioners towards improving HRA methods and their applications in the context of Industry 4.0.

Published: November 2022

AbstractThe parameter estimation for transmission systems is important to power flow analysis, planning the expansion of electric power systems, stability, dispatch and economic analysis. This type of task is developed through systems identification methods, being the least squares method and its variations the most common techniques to obtain the transmission line parameters. However, these techniques have some disadvantages, such as non‐recursive parameter estimation or the availability of an ideally transposed line, in order to address a problem with symmetric matrices, which simplifies the estimation process. In this paper, a non‐linear method (Extended Kalman Filter) is presented to obtain the states of the transmission line terminals jointly with the vectorized matrix of parameters; such approach is strongly affected by the initial conditions; these conditions are usually obtained manually, which requires a lot of time and effort. Therefore, an optimization method (Particle Swarm Optimization) is applied in order to improve the convergence of the EKF, which reduces the time for adjusting the hyper‐parameters and improves the estimated results. The proposed method showed accurate results for non‐transposed systems, and also in comparison with results obtained from the same EKF‐based method without the proposed optimization technique.
An autonomous emergency braking strategy based on non‐linear model predictive deceleration control

Published: November 2022

AbstractSurrogate safety measures (SSM) are used to assess the risk for autonomous emergency braking system (AEBS). Developing appropriate SSM and accurately executing the braking request are the key issues. Time‐to‐collision (TTC) is a typical time‐based SSM with limitations. By analyzing the braking process, this paper proposes a new SSM based on deceleration rate to avoid collision (DRAC). As the brake actuator, vehicle electronic stability control (ESC) system has many problems, such as large overshoot and pressure fluctuation. Considering the model of hydraulic control unit (HCU) and vehicle, a deceleration controller based on non‐linear model predictive control (NMPC) is proposed. Based on this, a layered AEBS architecture is proposed. The upper‐layer AEBS controller calculates the expected deceleration based on modified DRAC (MDRAC), and transmits it to the lower‐layer NMPC deceleration controller. Finally, the simulation and experimental tests are carried out. The results show that the system has a fast and stable response. In addition, the performance of the proposed AEBS strategy is tested according to the Euro‐NCAP test protocol. Comparing the results with the TTC method, the proposed method can improve the stability of the distance margin by more than 0.55 m, which ensures the safety and improves the stability of the vehicle.
Photocatalytic and eletrocatalytic activity of black TiO2 nanotube arrays by aluminothermic reduction
Authors: Li Bingchen , Jiang Ying , Liu Jiaming , Hui Kezhen , Guo Limin 
Published: November 2022

AbstractThe black TiO2 nanotubes arrays were prepared by anodizing and aluminothermic reduction process. The prepared samples were characterized by X‐ray diffraction (XRD), SEM, UV‐visible absorption spectroscopy and X‐ray photoelectron spectroscopy (XPS). The photochemical/electrical catalytic activity of the samples before and after blackening treatment was tested. Comparing with the raw TiO2, the macrostructure of the black TiO2 nanotube arrays changes a little, and the tubal walls become a little thicker and rough. The photocatalytic hydrogen production rate has an obvious enhancement (from 8.9 µmol cm−2 h−1 to 22.8 µmol cm−2 h−1) after the blackening treatment and the electrocatalytic H2 evolution rate is also improved with a lower onset potential. The increment of trivalent Ti3+ on the surface is confirmed by XPS and presented by the colour changing of the samples (from white colour to black). The hybrid energy band gap and reduced charge transfer barrier are proved to be essential in promoting the catalytic properties of the black TiO2 nanotube arrays.

AbstractA vertical cavity surface emitting laser (VCSEL) quick fabrication (VQF) process is applied to epitaxial materials designed for miniature atomic clock applications (MACs). The process is used to assess material quality and uniformity of a full 100 mm (4‐inch) wafer against the stringent target specification of VCSELs for MACs. Target specifications in optical power (>0.6 mW) and differential efficiencies (<0.5 W/A) are achieved over large portions of a wafer; however, the variation in the oxide aperture diameter is shown to limit the yield. The emission of the fundamental mode at 894.6 nm at 70 is met over a significant area of the wafer for ∼4 m aperture multi‐mode devices. The consideration of the on‐wafer variation reveals that further optimisation is required to increase the device yield to levels required for volume manufacture.

Authors: Kord Fahimeh , Rezanejad Mohammad , Sheikholeslami Abdolreza 
Published: November 2022

AbstractIn this paper, a novel high step‐up direct current (DC)‐DC converter, using switched‐capacitor (SC) cells, is proposed. Upon turning a set of switches in this converter on/off, the capacitors are connected to each other in a circuit configuration, and charged through the source. Then, the capacitors are reconnected in a different configuration by turning the switches off/on, and generate high output voltage. This modular converter is able to produce flexible, high output voltage from low input voltage sources. The proposed converter is accordingly studied and analysed. To verify the operation of the given converter, it is simulated via the MATLAB‐based Simulink software, and an experimental prototype is subsequently implemented on a laboratory scale.
Supporting access to key pan-European research infrastructures and international cooperation
Authors: Kinnunen Petri , Bignan Gilles , Pavel Gabriel , Esteban Gran Victor 
Published: November 2022

Large research infrastructures, especially nuclear ones, are extremely expensive to build and operate. Therefore, to develop expertise and competences in nuclear research is more efficient to have a limited number of complementary specialized large nuclear research infrastructures, shared by European researchers from different countries.
This paper describes three different actions to improve the European collaboration in the experimental nuclear research, namely open access to the nuclear research infrastructure of the JRC, the optimization of the use of research reactors in Europe and operation planning of the Jules Horowitz reactor currently under construction.
Supporting access to key pan-European research infrastructures strengthens research and innovation, avoiding duplication and optimising resources. It contributes to the European Research Area (ERA) and the European Strategy Forum on Research Infrastructures (ESFRI), as well as to maintaining competence in the EU, which is one of the objectives of the Euratom research and training programme.

Published: November 2022

In this paper, a novel X-band TM01–TE01 mode converter for high-power microwave (HPM) system is proposed. To realize the compact design, a helical corrugated waveguide with large deformation is employed to convert the TM01 mode into TE01 mode. By optimizing the structure parameters, the simulation results demonstrate that the maximum conversion efficiency of the proposed TM01–TE01 mode converter reaches 98.8% at 9.2 GHz. Moreover, this mode converter exhibits a conversion efficiency of over 95% in the operation band from 8.7 to 9.42 GHz, and the power capacity of the mode converter reaches GW-level in theory. More importantly, the overall longitudinal and transverse dimensions of the mode converter are less than three wavelengths. The results show the compact structure and high conversion efficiency of this mode converter, which has great potential application value in the HPM system.
A constructional account of the development of the Chinese stance discourse markerběnlái
Authors: Zhan Fangqiong 
Published: November 2022

AbstractThis paper examines the emergence of the Chinese adverbběnláiand its further development into a stance discourse marker (sdm). Most previous studies consider the epistemic modal adverbběnlái(‘indeed, truly’) to have originated from the temporal adverbběnlái(‘originally’). Based on the framework of constructionalisation (Traugott and Trousdale 2013) andVan de Velde et al.’s (2013)idea of multiple sources, I argue that the temporal adverb might not have been the only source for the modalběnláito occur. Furthermore, the modal adverb changed into ansdm, thereby signaling the speaker’s subjective evaluation while linking the coherence of the discourse. I argue that the change was enabled by both subjectification and analogisation. The exemplars to whichběnláiwas by hypothesis analogised include the extant discourse connectives (e.g.,kěshì) and the extant commentary pragmatic markers (e.g.,kěliánandsuǒxìng) (Fraser 2009).
Sneutrinos as two inflatons and curvaton and leptogenesis
Authors: Takahashi Tomo , Yamada Toshifumi , Yokoyama Shuichiro 
Published: November 2022

Abstract
We argue that sneutrinos can be embedded in a multi-field inflation framework where two inflatons and a curvaton simultaneously contribute to primordial fluctuations, which is consistent with current constraints on the spectral index and the tensor-to-scalar ratio from Planck and BICEP/Keck 2018. We also show that the same framework can also explain the baryon asymmetry of the Universe via leptogenesis realized by the decay of the lightest sneutrino. We investigate the parameter range for the scenario to work such as that of sneutrino masses. In particular, we show that the tensor-to-scalar ratio should be larger than 10-4 for a successful scenario.
Mass Distribution of Black Holes with Effects of Convective Carbon Shell Burning on Pair-instability Pulsation and Fe Core Collapse
Authors: Xin Wenyu , Nomoto Ken’ichi , Zhao Gang , Zhang Xianfei 
Published: November 2022

Abstract
Motivated by the determination of black hole masses with gravitational-wave observations, we calculate the evolution of massive stars through presupernova stages and obtain the mass distribution of black holes. In the first part, we calculate the evolution of He stars with masses of 30–120 M
⊙. We study in detail how convective carbon shell burning controls pair-instability pulsations before and during oxygen burning and determine their final fates. In the second part, we calculate the evolution of H-rich stars with initial masses of 13–80 M
⊙ until Fe core collapse and obtain the possible black hole mass range by applying the criterion of the compactness parameters. From these models, we predict the mass distribution of black holes for stars that undergo Fe core collapse and pair-instability pulsation. The predicted masses for black holes range from 4.2 to 46 M
⊙, which are consistent with the gravitational-wave observations.
Past and Future of a Type Ia Supernovae Progenitor Candidate HD 265435
Authors: Qi Wei-Zhong , Liu Dong-Dong , Wang Bo 
Published: November 2022

Abstract
As one of the most useful cosmological distance indicators, type Ia supernovae (SNe Ia) play an important role in the study of cosmology. However, the progenitors of SNe Ia are still uncertain. It has been suggested that carbon-oxygen white dwarf (CO WD)+He subgiant systems could produce SNe Ia through the double-degenerate (DD) model, in which the He subgiant transfers He-rich matter to the primary CO WD and finally evolves to another CO WD. Recently, a CO WD+He star system (i.e., HD 265435) has been discovered to be a new SNe Ia progenitor candidate based on the DD model. The orbital period of the system is about 0.0688 days, and the masses of the CO WD and the He star are 1.01 ± 0.15 M
⊙ and

⊙, respectively. In this work, we evolve a large number of primordial binaries to the formation of CO WD+He star systems and investigate the evolutionary history of HD 265435. We find that HD 265435 may originate from a primordial binary that has a 5.18 M
⊙ primary and a 3.66 M
⊙ secondary with an initial orbital period of 5200 days. The CO WD+He star system would be formed after the primordial binary experiences two common-envelope ejection processes. We also find that HD 265435 would evolve to a double WD system with a total mass of 1.58 M
⊙ after a stable mass-transfer process, and the double WD system would merge driven by gravitational wave radiation. We estimate that it would take about 76 Myr for HD 265435 to form an SN Ia. In addition, HD 265435 would be a potential target of space-based gravitational wave observatories (e.g., LISA, Taiji and TianQin).

with plasma in transport channel
Authors: Markov P.I. , Kniaziev R.R. , Sotnikov G.V. 
Published: November 2022

Abstract
The paper presents the results of numerical particle-in-cell simulation of the positron bunch focusing during acceleration in a plasma dielectric wakefield accelerator. The wakefield is excited by drive electron bunch in quartz dielectric tube, embedded in a cylindrical metal waveguide. The internal area of the dielectric tube is filled with plasma having in the general case the paraxial vacuum channel. Two different models of the plasma density radius-relationship are investigated: the homogeneous model and the inhomogeneous dependence characterized the capillary discharge. Results of the numerical particle-in-cell simulation show that a simultaneous acceleration and focusing of the test positron bunch in the wakefield is possible. The dependence of transport and acceleration of the positron bunch with change in the size of vacuum channel, waveguide length and the plasma density-radius model is studied.

Published: November 2022

Abstract
As a typical metal-organic framework (MOF), Mg-MOF74 can release biocompatible Mg2+ when the framework is degraded, and it has the potential to be used as filler in the field of bone tissue engineering. However, Mg-MOF74 has poor stability in aqueous environment and limited antibacterial ability, which limit its further development and applications. In this work, MgCu-MOF74 particles with different Cu content were synthesized through a facile one-step hydrothermal method. The physicochemical properties and water stability of the synthesized powders were characterized. The osteogenic potential of the MgCu-MOF74 particles on human osteogenic sarcoma cells (SaOS-2) was evaluated. The hybrid MgCu-MOF74 exhibited favorable water stability. These results indicated that MgCu-MOF74 enhanced cellular viability, alkaline phosphatase levels, collagen (COL) synthesis and osteogenesis-related gene expression. Moreover, the samples doped with Cu2+ were more sensitive to the acidic microenvironment produced by bacteria, and exhibited stronger antibacterial ability than Mg-MOF74. In conclusion, MgCu-MOF-74 with good water stability, osteogenic ability and antibacterial ability, which could be attributed to the doping of Cu2+. Hence, MgCu-MOF74 shows great potential as a novel medical bio-functional fillers for the treatment of bone defects.
