Morphogenesis of the Balbiani body in developing oocytes of an orthopteran, Metrioptera brachyptera, and multiplication of female germline mitochondria
Authors: Sekula Malgorzata , Tworzydlo Waclaw , Bilinski Szczepan M. 
Published: August 2020

AbstractBalbiani body (Bb) is a female germline specific organelle complex. Although the morphology and morphogenesis of the Bb have been analyzed in numerous vertebrate and invertebrate species, the role and ultimate fate of this organelle assemblage are still under debate. As a result, various functions have been attributed to the Bb in given animal lineages or even species. Our analyses showed that in the bush cricket, Metrioptera brachyptera, the Bb is an elaborate and highly dynamic structure positioned at one side of the oocyte nucleus. It forms in early previtellogenic oocytes and consists of two compartments: perinuclear and cytoplasmic. In the cytoplasmic compartment, characteristic complexes of nuage and polymorphous mitochondria are present. Computer‐aided 3D reconstructions revealed that mitochondria clustered around neighboring nuage accumulations remain in a physical contact and form an extensive, though dispersed network. As oogenesis progresses, nuage/mitochondria complexes are partitioned into progressively smaller entities that become separated from each other. Concurrently, the mitochondrial network splits into small individual mitochondria populating the whole ooplasm. Immunohistochemical analysis showed that the latter process involves dynamin‐related protein 1 (Drp1). Collectively, our findings suggest that in basal insect species, the Bb might be responsible for the selection as well as multiplication of the oocyte mitochondria.
A SPICE model of p‐channel silicon tunneling field‐effect transistors for logic applications

Published: August 2020

AbstractIn this study, we propose a SPICE model of p‐channel silicon tunneling field‐effect transistors (TFETs) for logic applications. To verify our model, electrical characteristics of fabricated p‐TFETs are calibrated by utilizing TCAD and SPICE simulations. We simulate various logic gates, such as complementary TFET (c‐TFET) inverters, c‐TFET NAND gates, and c‐TFET NOR gates using our TFET model. Our simulation shows that a c‐TFET inverter can be operated at VDD as low as 0.3 V and that c‐TFET logic gates based on our model can operate ~1000 times higher frequency than conventional TFET logic gates.

Published: August 2020

AbstractWe propose and experimentally demonstrate a temperature sensor based on a suspended‐core microstructure optical fiber (SCMF). The sensor is constructed by fusion splicing a piece of SCMF between two up‐tapers which act as light beam couplers. The Mach‐Zehnder interference (MZI) is formed by the silica core modes and the air cladding modes in the SCMF. The sensitivity of −0.011 rad/°C in the temperature range of 20°C to 90°C is achieved, which is more accurate and stable than conventional wavelength tracking method due to the phase demodulation method can avoid the effects of spectral noise, dip selection, and wavelength sampling rate on the wavelength tracking. In addition, our proposed sensor is inert to external environments such as strain and refractive index, which can well solve the problem of crosstalk during temperature sensing.
Passive needle guide tracking with radial acquisition and phase‐only cross‐correlation
Authors: Reichert Andreas , Reiss Simon , Krafft Axel Joachim , Bock Michael 
Published: August 2020

PurposeAcceleration of a passive tracking sequence based on phase‐only cross‐correlation (POCC) using radial undersampling.MethodsThe phase‐only cross‐correlation (POCC) algorithm allows passive tracking of interventional instruments in real‐time. In a POCC sequence, two cross‐sectional images of a needle guide with a positive MR contrast are continuously acquired from which the instrument trajectory is calculated. Conventional Cartesian imaging for tracking is very time consuming; here, a higher temporal resolution is achieved using a highly undersampled radial acquisition together with a modified POCC algorithm that incorporates the point‐spread‐function. Targeting and needle insertion is performed in two phantom experiments with 16 fiducial targets, each using 4 and 16 radial projections for passive tracking. Additionally, targeting of eight deep lying basivertebral veins in the lumbar spines is performed for in vivo proof‐of‐application with four radial projections for needle guide tracking.ResultsThe radially undersampled POCC sequence yielded in the phantom experiments a lateral targeting accuracy of 1.1 ± 0.4 mm and 1.0 ± 0.5 mm for 16 and 4 radial projections, respectively, without any statistically significant difference. In the in vivo application, a mean targeting duration of 62 ± 13 s was measured.ConclusionRadial undersampling can drastically reduce the acquisition time for passive tracking in a POCC sequences for MR‐guided needle interventions without compromising the targeting accuracy.
Domain recurrence and probabilistic analysis of residence time of stochastic systems and domain aiming control
Authors: Yin Juliang , Ding Deng , Khoo Suiyang 
Published: August 2020

SummaryThe problem of domain aiming control is formulated for a controlled stochastic nonlinear system, which involves regularity of the solution to the resulting closed‐loop stochastic system. To begin with, an extended existence and uniqueness theorem for stochastic differential equations with local Lipschitz coefficients is proven by using a Lyapunov‐type function. A Lyapunov‐based sufficient condition on nonregularity is also given. The notions of domain recurrence and residence time for stochastic nonlinear systems are introduced, and various criteria for the recurrence and nonrecurrence relative to a bounded open domain or an unbounded domain are provided. Furthermore, upper bounds of expectation and moment‐generating function of the residence time are derived. In particular, a connection between the mean residence time and a Dirichlet problem is investigated and illustrated with a numerical example. Finally, the problem of domain aiming control is considered for certain types of nonlinear and linear stochastic systems. Several examples are provided to illustrate the theoretical results.

Published: August 2020

Abstract
Purpose
Differences in the risk of childhood central nervous system (CNS) tumors by socioeconomic status (SES) may enhance etiologic insights. We conducted a nationwide register-based case–control study to evaluate socioeconomic differences in the risk of childhood CNS tumors in Denmark and examined whether associations varied by different SES measures, time points of assessment, specific tumor types, and age at diagnosis.

Methods
We identified all children born between 1981 and 2013 and diagnosed with a CNS tumor at ages 0–19 years (n = 1,273) from the Danish Cancer Registry and sampled four individually matched controls per case (n  = 5,086). We used conditional logistic regression models to estimate associations with individual-level and neighborhood-level socioeconomic measures.

Results
We observed elevated risks of ependymoma and embryonal CNS tumors in association with higher parental education (odds ratios (ORs) of 1.6–2.1 for maternal or paternal high education and ependymoma) and higher risk of all tumor types in association with higher maternal income, e.g., OR  1.93; 95% CI 1.05–3.52 for high versus low income for astrocytoma and other gliomas. Associations were often stronger in children diagnosed at ages 5–19 years. We found little evidence for an association with neighborhood SES.

Conclusion
This large nationwide register study with minimal risk of bias showed that having parents with higher educational level and a mother with higher income was associated with a higher risk of childhood CNS tumors. Bias or under-ascertainment of cases among families with low income or basic education is unlikely to explain our findings.
Learning about climate change in, with and through art
Authors: Bentz Julia 
Published: August 2020

AbstractEffective strategies to learn about and engage with climate change play an important role in addressing this challenge. There is a growing recognition that education needs to change in order to address climate change, yet the question remains “how?” How does one engage young people with a topic that is perceived as abstract, distant, and complex, and which at the same time is contributing to growing feelings of sadness, hopelessness, and anxiety among them? In this paper, I argue that although the important contributions that the arts and humanities can make to this challenge are widely discussed, they remain an untapped or underutilized potential. I then present a novel framework and demonstrate its use in schools. Findings from a high school in Portugal point to the central place that art can play in climate change education and engagement more general, with avenues for greater depth of learning and transformative potential. The paper provides guidance for involvement in, with, and through art and makes suggestions to create links between disciplines to support meaning-making, create new images, and metaphors and bring in a wider solution space for climate change. Going beyond the stereotypes of art as communication and mainstream climate change education, it offers teachers, facilitators, and researchers a wider portfolio for climate change engagement that makes use of the multiple potentials of the arts.
Product-requirement-model to approach the identification of uncertainties in battery systems development

Published: August 2020

AbstractElectric mobility is on the verge of becoming a mass market. Major automotive OEMs have initiated programs to electrify their product portfolio. This transition poses new challenges and requires new innovative concepts in automotive development processes, especially for battery systems as the key component within electric powertrains. Battery system costs account for up to 40% of the electric vehicle’s total costs. Additionally, development cycles of battery systems for automotive applications are characterized by long development periods. Hence, the initiatives to advance electrification result in numerous development projects affiliated with significant development expenses. Battery systems can be referred to as mechatronic and electrochemical systems. They require a complex interaction of diverse scientific and engineering disciplines. Fast innovation cycles have effects regarding product requirements and assumptions towards their allocation. Hereby, uncertainties can lead to risks within development projects, especially in terms of time and costs. In current development processes, necessary changes are only dealt with reactively, causing unplanned additional expenses and delays. Thus, there is need for handling potential changes proactively, i.e. managing uncertainties leading to those changes as early as possible. New methods are necessary to identify and handle uncertainties of complex product systems within requirements engineering. An approach towards comprehensive uncertainty management is taken within this publication.

AbstractThis research was undertaken on the lands of the Wurundjeri people of the Kulin nation. We pay our respects to Elders of the past, present and emerging, and also acknowledge the generous contribution to this research made by women and their families and Victorian Aboriginal Child Care Agency (VACCA) staff. Aboriginal Cradle to Kinder (AC2K) is a home-visiting and advocacy programme focussed on promoting Aboriginal maternal and child health during both pre- and postnatal stages of parenthood which was delivered by VACCA, an Aboriginal Community Controlled Organisation. While there have been some feasibility assessments conducted on AC2K, no study to date has evaluated the impact of this programme from the perspective of neither the women nor the staff who deliver the programme. The aim of this study, therefore, was to evaluate how both the women and the staff evaluated the AC2K programme, namely the strengths, limitations and recommendations of the programme. Through consultation with VACCA, this study used a qualitative approach using interpretative phenomenological analysis to explore the processes underpinning the programme coupled with participants’ experiences of the programme. A co-design process was used in the development of interview questions, and a total of seven women and six workers participated in semi-structured interviews. The results revealed three superordinate themes across both participant groups: cultural connection (i.e. how well the programme facilitates cultural connection), system complexities (i.e. caseloads, staff turnover and child protection [CP] difficulties) and programme features (i.e. parenting enhancement and unique programme benefits). The processes, and the programme more broadly, were evaluated positively by both the women and staff who supported its delivery. Specifically, a greater connection to culture, increased parenting skills and unique programme benefits were reported. However, there were recommendations on how the programme could be further strengthened, including negotiable caseloads with the Department and improved partnership with CP. These changes can help to further improve the experiences of both the women and their workers when engaging in Aboriginal specific maternal health and well-being supports.

Published: August 2020

Abstract
Coronavirus disease 2019 (COVID-19) is a global health threat. A hospital in Zhuhai adopted several measures in Fever Clinic Management (FCM) to respond to the outbreak of COVID-19. FCM has been proved to be effective in preventing nosocomial cross infection. Faced with the emergency, the hospital undertook creative operational steps in relation to the control and spread of COVID-19, with special focuses on physical and administrative layout of buildings, staff training and preventative procedures. The first operational step was to set up triaging stations at all entrances and then complete a standard and qualified fever clinic, which was isolated from the other buildings within our hospital complex. Secondly, the hospital established its human resource reservation for emergency response and the allocation of human resources to ensure strict and standardised training methods through the hospital for all medical staff and ancillary employees. Thirdly, the hospital divided the fever clinic into partitioned areas and adapted a three-level triaging system. The experiences shared in this paper would be of practical help for the facilities that are encountering or will encounter the challenges of COVID-19, i.e. to prevent nosocomial cross infection among patients and physicians.

AbstractAim:Vestibular schwannomas (VS) are benign slow-growing tumours treated either with microsurgery or stereotactic radiosurgery (SRS) or both. The aim of this study was to correlate the outcome factors—tumour control and adverse factors—facial nerve function and hearing loss with patient and treatment factors.Materials and methods:A retrospective review of the records of 98 patients with 99 VS treated from June 2007 to June 2014, all patients receiving Linear Accelerator (LINAC)-based SRS.Results:Median follow-up period was 5·6 years (range: 1–12 years). The response to treatment was stable disease in 37 (37·4%), regression in 46 (46·5%), asymptomatic minimal progression in 9 (9·1%) and symptomatic progression in 5 (5%) and unknown in 2 (2%) patients. There was no evidence of SRS induced tissue damage on magnetic resonance scans for any. Hearing preservation rate after SRS was 92%. The patients who developed worsening of facial function were predominantly in the cohort that had prior surgery.Findings:SRS is an effective modality to treat VS lesser than 3 cm in size. Tumour control rate was 95% with a median follow-up period of 5·6 years. The complication rates were 8% each for facial function worsening and worsening of hearing. Prior surgery was a statistically significant factor that affected facial nerve function deterioration.
The role of protein arginine methyltransferases in kidney diseases
Authors: Zhang Chunyun , Zhuang Shougang 
Published: August 2020

Abstract
The methylation of arginine residues by protein arginine methyltransferases (PRMTs) is a crucial post-translational modification for many biological processes, including DNA repair, RNA processing, and transduction of intra- and extracellular signaling. Previous studies have reported that PRMTs are extensively involved in various pathologic states, including cancer, inflammation, and oxidative stress reaction. However, the role of PRMTs has not been well described in kidney diseases. Recent studies have shown that aberrant function of PRMTs and its metabolic products—symmetric dimethylarginine (SDMA) and asymmetric dimethylarginine (ADMA)—are involved in several renal pathological processes, including renal fibrosis, acute kidney injury (AKI), diabetic nephropathy (DN), hypertension, graft rejection and renal tumors. We aim in this review to elucidate the possible roles of PRMTs in normal renal function and various kidney diseases.

1200 V buried gate fin p‐body IGBT with ultralow on‐state voltage and good short circuit capability

Published: August 2020

A buried gate fin p‐body insulated gate bipolar transistor (BG‐Fin‐P IGBT) is proposed to achieve ultralow on‐state voltage drop (V CE(sat) ) and good short‐circuit (SC) ruggedness simultaneously. A buried gate is introduced at the bottom part of the fin structure, forming a local region with the nanoscale mesa width, which enhances the conductivity modulation effectively. Meanwhile, a relatively wide mesa width (>0.5 μm) can be adopted at the main fin structure to maintain a good SC capability. Compared to the previously reported ultra‐narrow‐mesas fin p‐body IGBT, simulation results reveal that the V CE(sat) of the BG‐Fin‐P IGBT is reduced from 1.39 to 1.03 V at the current density of 100 A/cm2 without SC ability degradation. Meanwhile, more than 10 μs short circuit withstand time is enabled at the junction temperature of 423 K for all structures. Moreover, the proposed structure can avoid a fabrication difficulty of the emitter contact when a very narrow mesa width (∼30 nm) is required to achieve the ultralow V CE(sat), which brings design freedom on the device's structure.
Face identification using millimetre‐wave radar sensor data
Authors: Kim J. , Lee J.‐E. , Lim H.‐S. , Lee S. 
Published: August 2020

In this Letter, the authors propose a face identification method using radar sensor data. They use a frequency‐modulated continuous wave radar sensor that utilises a centre frequency of 61 GHz and a bandwidth of 6 GHz. Then, they accumulate radar data by transmitting and receiving radar signals on human faces. Finally, they use a convolutional neural network (CNN) to distinguish radar signals reflected from different human faces. In this network, signals received from multiple antenna elements are synthesised in parallel to make the radar signals into an image that is the input form of the CNN. The accuracy of face recognition through the CNN is . In addition, they also collect radar data when the same subjects wear cotton masks. Within their entire dataset, wearing a mask does not significantly affect the accuracy of the radar‐based face recognition method.
