Introduction: Innovations in Treatment for Children With Speech Sound Disorders
Authors: Farquharson Kelly , Tambyraja Sherine 
Published: June 2022

Purpose:
There is a clear need for effective and efficient interventions for children with speech sound disorder (SSD) that can be implemented in both clinical and school-based settings.

Method:
This forum was created for any clinician who treats SSDs. We asked the invited authors to include immediately actionable information, such as therapy activities, tips for goal writing or progress monitoring, assessment processes, and frameworks for conversations with parents.

Results:
We have curated nine scientifically based articles that highlight the heterogeneity of SSDs and how various subpopulations require uniquely tailored interventions. Some children with SSDs require treatment approaches that are more heavily embedded in phonological theories (e.g., maximal or multiple oppositions) or that extend beyond speech production and include speech perception and phonological awareness skills. Clinicians also need to be mindful of not only which sounds are affected, but which kinds of errors a child is making. For instance, lateral lisps and residual speech sound errors should be evaluated and treated differently from other kinds of speech sound errors. There are certainly subpopulations of children with SSDs for whom there is extremely limited data upon which speech-language pathologists can base clinical decisions, such as children under the age of 3 years or children who are multilingual. Finally, there is a crucial need to better understand the social–emotional impacts of SSDs. Tools to aid in including social–emotional data within assessment and intervention outcomes are also included in this forum.

Conclusion:
The traditional articulation approach is the most commonly used approach in school-based settings; however, there are many children for whom this approach is not appropriate. We hope to provide a robust resource for busy school-based speech-language pathologists who treat children with SSD—specifically, we hope clinicians embrace the opportunity to “think outside the box” of traditional articulation therapy.

Published: June 2022

AbstractAiming to help improve quality of life of the visually impaired people, this paper presents a novel wearable aid in the shape of a helmet for helping them find objects in indoor scenes. An object‐goal navigation system based on a wearable device is developed, which consists of four modules: object relation prior knowledge (ORPK), perception, decision and feedback. To make the aid also work well in unfamiliar environment, ORPK is used for sub‐goal inference to help the user find the target goal. And a method that learns the ORPK from unlabelled images by utilising a scene graph and knowledge graph is proposed. The effectiveness of the aid is demonstrated in real world experiments.

Published: June 2022

AbstractAccurate knowledge of Balise dynamic performance is essential for train position perception and safe operation. For the Balise in high‐speed railway, whose performance under dynamic energy harvesting is affected by the train operation and environmental uncertainty, such knowledge is even more critical. This study proposes a new performance analyse method, which analyses the dynamic input performance of Balise by quantitatively expressing the train operation and environmental uncertainty. The complete electrical model of the Balise consisted of radio frequency energy harvesting and frequency shift keying signal transmitting is developed, the dynamic output parameters such as output frequency and response time of the Balise are investigated and analysed. The correctness and effectiveness of the proposed electrical model are verified by the input to output characteristic experiment and simulation. Different case studies are carried out to analyse the dynamic input and output performance of Balise under dynamic energy harvesting. Simulation results show that the train operation and environmental media has a great effect on the input performance of the Balise. However, when the 7.15 V amplitude limiting strategy is adopted, the standard deviation of the main lobe zone in the dynamic input induced voltage envelope can be reduced by up to 86%. Moreover, the investigation reveals that the equivalent load in the electrical model has a greater effect on the output performance of the Balise compared with the dynamic energy harvesting.

Published: June 2022

AbstractIn this case report, we report a case of bronchoperitoneal fistula secondary to pneumonia in a 25-year-old male patient who presented with pain abdomen and fever with provisional diagnosis of duodenal perforation and air under right diaphragm in chest radiograph. Diagnosis of bronchoperitoneal fistula was made on computed tomographic findings, which showed consolidation and small cavity in the right lower lung lobe communicating with a loculated air pocket in the right subphrenic space through a right hemidiaphragmatic defect. Knowledge of this entity is important as fistula can be overlooked and can lead to mismanagement.
Key Messages
Bronchoperitoneal fistula is rare entity that can be overlooked in imaging and can lead to misinterpretation and mismanagement as hollow viscus perforation.

Abstract
Background Microvascular hepatic artery reconstruction (MHAR) is associated with decreased rates of hepatic artery thrombosis (HAT) in living donor liver transplantation (LDLT). There is a paucity of literature describing the learning points and initiation of this technique at the institutional level. The objective of this study is to report our institutional experience using MHAR in adult LDLT with a focus on technique and outcomes.
Methods A retrospective review of adult patients who underwent LDLT from January 2012 to December 2020 was conducted. Patients were divided into two groups, those who underwent LDLT without MHAR and with MHAR. We analyzed cases for technical data including donor and recipient artery characteristics, anastomotic techniques, intraop events, and postop complications. A Mann–Whitney test was performed to compare outcomes between non-MHAR and MHAR patients.
Results Fifty non-MHAR and 50 MHAR patients met inclusion criteria. Median age at transplantation was 58 (interquartile range [IQR] 11.8) and 57.5 years (IQR 14.5), respectively. Median follow-up for MHAR patients was 12.8 months (IQR 11.6). The most common recipient arteries were the right hepatic artery (HA) (58%) and left HA (20%). Median size of recipient and donor arteries were 3.3 mm (IQR 0.7) and 3.1 mm (IQR 0.7), resulting in a median mismatch size of 0.3 mm (IQR 0.4). Median microanastomosis time was 44 minutes (IQR 0). HAT, graft failure, and mortality rates were higher in the non-MHAR cohort (6% vs. 0%, 8% vs. 0%, and 16% vs. 6%, respectively); however, these did not reach statistical significance.
Conclusion This study found lower rates of HAT and graft failure after implementing MHAR, though statistical significance was not achieved. Larger cohort studies are needed to further assess the potential benefit of MHAR in adult LDLT. From our experience, MHAR requires cooperation between the transplant and microsurgical teams, with technical challenges overcome with appropriate instrumentation and planning.

Published: June 2022

AbstractThis paper explores attitudes to and experiences of patron banning policy (which prohibits an individual from entering a nightlife area or venue after engaging in anti-social behaviour) in Queensland, Australia. Key informant interviews were conducted with 66 participants from health, justice, industry, and government sectors across the state. Interviews were semi-structured, and transcripts were examined using thematic analysis. Overall, key informants reported that patron banning provisions helped to keep out customers who cause problems in venues and that ID scanners helped to enforce bans. There was some concern about displacement of banned patrons to other nightlife areas, the discretionary nature of venue bans, the potential for banning notices to be misused, and a general perception that police-imposed bans should be longer than the current 10 days. The majority of interviewees were supportive of patron banning and felt that it could (positively) affect patron behaviours. A number of recommendations were suggested to refine the framing and operation of Queensland’s banning policy.

Published: June 2022

Context Salt stress harms plant growth and limits crop productivity. Autophagy is a material decomposition and metabolism pathway that is central to regulating plant responses to environmental stimuli and may be employed in plant breeding for stress tolerance. The autophagy-related gene ATG8 has become an essential tool for monitoring autophagic activity. Aims We aimed to determine the effects of increased autophagic activity via overexpression of ATG8 on tolerance of wheat (Triticum aestivum L.) seedlings to NaCl stress. Methods Salt-tolerant wheat cv. Jimai22 was used to produce TaATG8a-overexpressing wheat seedlings using Foxtail mosaic virus based virus-mediated overexpression technology. TaATG8a-overexpressing seedlings were exposed to NaCl stress for 6 days. Key results Overexpression of TaATG8a enhanced autophagic activity and improved salt stress tolerance of wheat seedlings. Overexpression of TaATG8a also reduced damage to photosystem II, reduced excess accumulation of reactive oxygen species, increased the activities of superoxide dismutase, peroxidase and catalase, and suppressed programmed cell death in wheat seedling leaves during NaCl treatment. Conclusions Overexpression of TaATG8a conferred higher tolerance of wheat seedlings to NaCl stress and suppressed salt-induced programmed cell death, accompanied by increased autophagic activity. Implications This study provides genetic resources and a theoretical basis for stress tolerance breeding in wheat.
Effect of three-body interactions on Bénárd–von Kármán vortex street in quasi-2D Bose–Einstein condensate

Published: June 2022

Abstract
The dynamical behaviors of a quasi-2D Bose–Einstein condensate (BEC) with three-body interactions through a moving obstacle potential are studied numerically. Various vortex structures are discovered under different strength of three-body interactions when the two-body interaction is attractive or repulsive. When the width and moving velocity of the obstacle potential reach critical value, periodic anti-symmetric double-row vortex pairs will be released alternately in BEC, and a Bénárd–von Kármán (BvK) vortex street will be formed eventually. We noticed that the BvK vortex street can be excited when the three-body interactions are taken into account even if the two-body interaction is attractive. The mean value of the distance between two vortex rows to the distance between two vortex pairs in the same row is about 0.2. It is slightly smaller than the stability condition 0.28 without considering the three-body interaction. The parameter regions of vortex patterns at different three-body interaction are determined. It is found that an appropriate value of three-body interaction with larger velocity and lesser width is favorable to the formation of BvK vortex street. In a pair of point vortices, the distance and angular velocity between them are nearly invariant while they rotate around their center. The internal rule of vortex pair are also analyzed by calculating the drag force acting on the obstacle potential. Finally, we proposed an experimental protocol to realize the vortex street in 87Rb BEC with three-body interactions.

Published: June 2022

Abstract
Deformation-induced rejuvenation is a promising strategy to improve the macroscopic plasticity of metallic glasses (MGs). Here, molecular dynamics simulations are performed to investigate the rejuvenated MGs’ atomic structure and mechanical behavior with high-pressure torsion (HPT) processing. The HPT induces the formation of soft and hard regions in MGs, which dramatically improves the microstructural heterogeneity. Potential energy, pair distribution function, short-range order, medium-range order, and vibrational behavior in HPT-deformed MGs are characterized. The microstructure of soft regions similar to the configuration slightly above the glass transition temperature can be adjusted by torsion angle, ultimately controlling the transformation of MGs from brittleness to ductility. These findings provide valuable guidelines for the design of MGs with enhanced deformability.

with a general nonlinearity f. Using the improved vorticity method, we construct a family of steady vortex rings which constitute a desingularization of the classical circular vortex filament in the whole space. The requirements on f are very general, and it may not satisfy the Ambrosetti–Rabinowitz condition. Some qualitative and asymptotic properties are also established.
Hidden spatiotemporal symmetries and intermittency in turbulence
Authors: Mailybaev Alexei A 
Published: June 2022

Abstract
We consider general infinite-dimensional dynamical systems with the Galilean and spatiotemporal scaling symmetry groups. Introducing the equivalence relation with respect to temporal scalings and Galilean transformations, we define a representative set containing a single element within each equivalence class. Temporal scalings and Galilean transformations do not commute with the evolution operator (flow) and, hence, the equivalence relation is not invariant. Despite of that, we prove that a normalized flow with an invariant probability measure can be introduced on the representative set, such that symmetries are preserved in the statistical sense. We focus on hidden symmetries, which are broken in the original system but restored in the normalized system. The central motivation and application of this construction is the intermittency phenomenon in turbulence. We show that hidden symmetries yield power law scaling for structure functions, and derive formulas for their exponents in terms of normalized measures. The use of Galilean transformation in the equivalence relation leads to the quasi-Lagrangian description, making the developed theory applicable to the Euler and Navier–Stokes systems.
Current redistribution during inhomogeneous quench of 2G HTS tapes

Published: June 2022

Abstract
Inhomogeneous temperature elevations, also called hot spots, occurring in second generation high-temperature superconductor (2G HTS) tapes may lead to their destruction. A better understanding of inhomogeneous quenches would contribute to develop strategies to better protect superconducting devices based on 2G HTS tapes against hot spots. To do so, we investigated the current redistribution around a dissipative zone in a 2G HTS tape with a combination of experiments and numerical simulations based on the finite element method (FEM). Firstly, the inhomogeneous heat generation in a commercial 2G HTS bare tape (without copper cladding) was observed through the visualization of bubble generation. Secondly, the current redistribution around a dissipative zone in commercial 2G HTS bare tapes from two different manufacturers was investigated using voltage taps on both sides of the tape. The measured voltages showed that the current redistribution around the dissipative area in the top stabilizer layer of the tape is different from that in the bottom stabilizer layer. Using a 3D electro-thermal FEM model, we reproduced these behaviors, assuming a HTS tape architecture with an inhomogeneous local critical current density. Finally, using the same FEM model, we explored the impact of a lack of silver on one lateral side of a 2G HTS tape. Our results indicate that such a lack of silver does not critically affect the quench dynamics.
Dual dielectric grating-assisted enhancement of Goos-Hänchen shift in monolayer graphene
Authors: Ma Shanshan , Zhu Xiaojun , Lu Delian , Da Haixia 
Published: June 2022

Abstract
Recently, the dielectric gratings have been used in enhancing the Goos-Hänchen (GH) shifts of monolayer graphene. However, many of these structures are limited within single dielectric grating. Dual dielectric gratings are compelling candidates for the manipulation of the light–matter interaction owing to their flexible degree of freedom in geometrical parameters. Here, we present the GH shift of the reflected wave in the dual dielectric grating layers by using rigorous coupled-wave analysis and stationary phase method, where a monolayer graphene is placed over the lower dielectric grating layer and the upper and lower dielectric grating layers have different filling factors. It is found that a relatively large GH shift, with amplitude up to more than 8000 times of the incident wavelength, can be achieved in the dual dielectric grating layers with monolayer graphene due to the joint excitation of the guided mode resonance in both the upper and lower dielectric grating layers. In addition, we can control the magnitude and position of GH shifts by changing chemical potential of monolayer graphene and the geometrical parameters of the dual dielectric grating layers. Our work opens a possibility for the improvement of the GH shift in the combined structure with the dual dielectric grating layers and the two-dimensional layered structure, which might enable the novel optoelectronic devices.
Sophisticated acoustofluidic patterns generated in quasi-Sierpiński-carpet shaped chambers with heterogeneous radiation surface distributions

Published: June 2022

Abstract
In this research, an original strategy to generate diversified acoustofluidic fields in quasi-Sierpiński-carpet shaped chambers has been proposed and simulated for patterned manipulation of massive micro-scale particles. All of the structural elements in the fractalized chambers are symmetrical in spatial arrangement, and all radiation surfaces possess the same setting of input frequency point and oscillation amplitude along individual normal direction. Plenty of splendid acoustofluidic patterns can be obtained in the originally-static quasi-Sierpiński-carpet shaped chambers generated at different levels of recursion without complicated parameter modulation. The simulation results of acoustofluidic distributions together with micro-scale particle movement trajectories under different oscillation conditions further demonstrate the manipulation functionality of these artificially-designed devices. In comparison with the existing structural design schemes of miniaturized lab-on-a-chip systems, the introduction of fractal features like Sierpiński carpet/triangle and Koch snowflake can provide extraordinary insights and broaden application prospects of acoustofluidics, which is conducive to ultrasonic micro/nano manipulations from simplification to pluralism. The preliminary work shows the possibility of utilizing Sierpiński-type fractal structures as amenable components to customize acoustofluidic fields for the investigation of topographical manipulation of biological samples and orientational manoeuvre of micro/nano-scale machines in ways that are not achievable via traditional approaches.
The kilogram: inertial or gravitational mass?
Authors: Mana G , Schlamminger S 
Published: June 2022

Abstract
With the redefinition of the international system of units, the value of the Planck constant was fixed, similarly to the values of the unperturbed ground state hyperfine transition frequency of the 133Cs atom and speed of light in vacuum. Theoretically and differently from the past, the kilogram is now explicitly defined as the unit of inertial mass. Experimentally, the kilogram is realized by atom count or the Kibble balance. We show that only the former method measures the inertial mass without assuming the universality of free fall. Under ordinary circumstances, the results obtained by the Kibble balance require the equivalence of inertial and gravitational mass. Therefore, the agreement between the two measures can be interpreted as a test of the equivalence principle.

Abstract
Large-amplitude edge-localized modes (ELMs) are a major concern in the development of tokamak fusion energy. According to the peeling–ballooning theoretical model, effective current drive in the pedestal region of high-confinement (H-mode) tokamak plasmas can alter the current profile in this region and hence affect ELM instabilities. Using ray-tracing and Fokker–Planck quasilinear codes, effective and localized current drive by electron cyclotron (EC) waves in the H-mode pedestal region is studied in this paper. Numerical investigations are performed under present-day medium-sized tokamaks with an aspect ratio (A = R/a) covering a typical range of [2.7, 4.0]. Localized non-inductive current can be generated effectively by the Ohkawa mechanism of EC waves in the low-electron collisionality H-mode pedestal region. The Ohkawa mechanism-dominated current drive (OKCD) is much more effective than traditional electron cyclotron current drive (ECCD), which is the Fisch–Boozer mechanism-dominated one. Under 1–2 MW EC power, the current density of both co-OKCD and counter-OKCD has the same magnitude as edge bootstrap current density, which is calculated using the Sauter model. However, edge ECCD is much smaller than the bootstrap current. Consequently, the use of edge ECCD to control ELM failed in experiments, and only the EC heating can affect ELM behavior. Simulations on OKCD are performed in the H-mode pedestal region of realistic DIII-D tokamak plasma, and the results also support the above conclusions. The dependence of effective edge OKCD on the ratio of magnetic field and EC frequency is also found in tokamaks with a typical aspect ratio range. This work opens up a new possible field for active control of ELMs (triggering or suppressing an ELM) by edge current drive in present-day medium-sized tokamaks.
