Published: July 2021

Abstract
Background Extracorporeal membrane oxygenation (ECMO) provides circulatory support in children with congenital heart disease, particularly in the setting of cardiopulmonary failure and inability to wean from cardiopulmonary bypass. This study summarized the clinical application of ECMO in the treatment of heart failure after cardiac surgery in neonates.
Materials and Methods Clinical data of 23 neonates who received ECMO support in our center from January 2017 to June 2019 were retrospectively analyzed.
Results Twenty-three neonates, aged from 0 to 25 days and weight between 2,300 and 4,500 g, with heart failure postcardiotomy were supported with ECMO. The successful weaning rate was 78.26% and discharge rate was 52.17%. Bleeding and residual malformation were the most common complications. The univariate analysis showed that nonsurvivors were related to the factors such as higher lactate value of ECMO 12 and 24 hours (p = 0.008 and 0.001, respectively), longer time to lactate normalization (p = 0.001), lactate > 10 mmol/L before ECMO (p = 0.01), lower weight (p = 0.01), longer ECMO duration (p = 0.005), lower platelet count (p = 0.001), more surgical site bleeding (p = 0.001), and surgical residual malformation (p = 0.04). Further logistic regression analysis revealed that higher lactate value of ECMO 24 hours (p = 0.003), longer ECMO duration (p = 0.015), and surgical site bleeding (p = 0.025) were independent risk factors.
Conclusion ECMO was an effective technology to support the neonates with cardiopulmonary failure after open heart surgery. Control the lactate acidosis and surgical site bleeding event may be helpful for patients' recovery.

Published: July 2021

Objective This study was aimed to assess the association between ovarian hyperstimulation syndrome (OHSS) and pregnancy complications among women who conceived following fertility treatment.
Study Design A retrospective population-based cohort study, including all singleton deliveries of patients conceived following ovulation induction (OI) or in vitro fertilization (IVF) between 1988 and 2016, was conducted. All births occurred in a single tertiary medical center. A comparison was performed between deliveries of women who had experienced OHSS at early gestation and subsequently had a pregnancy and women without OHSS. Women lacking prenatal care, multiple gestations, and stillbirths were excluded from the analyses. A multivariable logistic regression model was used to control for confounders.
Results During the study period, 351,373 deliveries met the inclusion criteria, of which 6,748 were deliveries of infants who were conceived by either IVF or OI. Of this study population, 105 cases (1.6%) composed the exposed group, that is, women who had experienced OHSS with a subsequent live birth. In the multivariate analyses, after controlling for confounders, OHSS was not found as an independent risk factor for preeclampsia, gestational diabetes mellitus (GDM), intrauterine growth restriction (IUGR), preterm delivery (both <37 and <34 weeks), low birth weight (LBW), very LBW (VLBW), small for gestational age (SGA), and caesarean delivery. In a subanalysis conducted solely on the IVF population, similar results were found, aside from the association between OHSS and preterm delivery before 34 weeks of gestation which was statistically significant (adjusted odds ratio [AOR] = 2.3 95% confidence interval [CI]: 1.0–5.3, p = 0.049).
Conclusion In our population, OHSS was not found as a risk factor for adverse pregnancy and perinatal outcome. In IVF patients, OHSS is a risk factor for preterm delivery before 34 weeks of gestation.

Authors: Bushman Elisa T. , Blanchard Christina , Sinkey Rachael G. , Harris Stacy , Casey Brian , Tita Alan T. , Ramani Manimaran , Harper Lorie M. 
Published: July 2021

Objective We sought to determine if variation in head circumference (HC) within the range of normal (5th–10th and 90th–95th percentile) is associated with poor neurodevelopmental outcomes (NDO), which defined as mild or moderate delay by Bayley II psychometrics (BSID-II).
Study Design This is a secondary analysis of a randomized controlled trial assessing the benefits of magnesium for the prevention of cerebral palsy. Fetuses with a normal HC at birth defined as within 5th to 95th percentile were included. NDO were assessed at age 2 with BSID-II. Moderate delay was defined as a score <70 and mild delay as <85. HC was classified as small normal (5th–10th percentile), normal (10th–90th percentile), and large normal (90th–95th percentile). Logistic regression models adjusted for confounding. Linear regression models estimated the impact for every 1 cm of change in HC.
Results Of 1,236 included infants, 111 (8%) had small normal HC; 1,058 (85%) had normal HC; and 67 (5%) had large normal HC. Baseline characteristics were similar between groups. There was no association with changes in HC within the range of normal and developmental indices. When considered as a continuous variable, every 1 cm increase in HC was also not associated with a significant change in developmental indices.
Conclusion Within the normal range (5th–95th percentile), changes in HC did not correlate with changes in NDO at 2 years as measured by Bayley II scales.

Cardiovascular Phenotypic Spectrum of 1p36 Deletion Syndrome
Authors: Kaur Tripat , Sriram Chenni S. , Prasanna Priyanka , Kohli Utkarsh 
Published: July 2021

AbstractChromosome 1p36 deletion syndrome is a common genetic anomaly (prevalence: 1 in 5,000–1 in 10,000). Despite reports of cardiovascular involvement, the cardiovascular phenotypic spectrum of patients with 1p36 deletion syndrome is not well characterized. In this article, we reported the clinical course of a full-term African American boy with chromosome 1p36 deletion syndrome and neonatal onset of severe cardiac disease with moderate-to-severe biventricular dysfunction and severe pulmonary hypertension. Early neonatal onset presentation of 1p36 deletion syndrome is rare and might be associated with a more guarded prognosis. This case based study is supplemented by a comprehensive review of cardiovascular involvement in this relatively common genetic syndrome.
Feminist digital diplomacy and foreign policy change in Sweden
Authors: Aggestam Karin , Rosamond Annika Bergman , Hedling Elsa 
Published: July 2021

AbstractThis article analyses how the launch of Sweden’s feminist foreign policy marked a change in Sweden’s digital diplomatic efforts. It draws on three strands of research: digital diplomacy, foreign policy analysis (FPA) and feminist scholarship. Informed by FPA, the article explores the relevance of political leadership, bureaucratic agency and political context as drivers of policy change, and, specifically, Sweden’s feminist digital diplomacy. The article provides an empirical case analysis of Sweden’s foreign policy change and conduct of digital diplomacy during the period 2006–2020. It draws on documents available on the official websites of the Government Offices of Sweden and the Ministry for Foreign Affairs, including sites such as SwedenAbroad and Swedish Foreign Policy Stories. The article concludes that Sweden acted on a window of opportunity in global politics, which advanced a novel feminist digital diplomacy. Sweden’s competitive edge was based on a strong transformative political leadership in foreign policy, state feminism and an early engagement of digital diplomatic management of its state image online.
Gram-negative outer-membrane proteins with multiple β-barrel domains
Authors: Solan Ron , Pereira Joana , Lupas Andrei N. , Kolodny Rachel , Ben-Tal Nir 
Published: July 2021

Significance
All currently known architectures of outer-membrane beta barrels (OMBBs) have only one barrel. While the vast majority function as oligomers, with barrels from different chains packing against each other in the membrane, it was assumed that these multiple chains are needed to form multibarrel structures. And yet, here we show that multibarrel chains exist. Using state-of-the-art sequence and structure analysis tools, we report the discovery of more than 30 multibarrel architectures from gram-negative bacteria. The discovery of these architectures reveals another interesting chapter in OMBB evolution and has implications for protein engineering. The evolutionary advantages of multibarrels are yet to be discovered.
On the etymology of the Japanese plural suffix and its possible connection to Korean
Authors: Francis-Ratte Alexander 
Published: July 2021

Abstract
This paper presents an etymological analysis of the Japanese plural suffix tachi, Old Japanese tati. I propose that tati originates from a grammaticalization of an earlier Pre-Old Japanese phonological form *totwi, the non-bound reflex of which is the Old Japanese quasi-collective marker dwoti ‘fellow (person), everyone, together’. The reconstruction of a Pre-Old Japanese stem *totwi (Pre-Proto-Japanese /*tətəj/) with quasi-collective and plural function clarifies the possible connection of the Japanese plural suffix to the Korean plural suffix tul (Middle Korean tólh), which Whitman (1985, p. 217) proposed to be cognates but which has since been criticized on phonological and distributional grounds. I show that reconstructing the earliest form of the Japanese plural suffix as /*tətəj/ resolves each of the three phonological issues with the Japano-Koreanic comparison, creates a better morphosyntactic match between the two languages, and rules out a loanword relationship of the Japanese and Korean forms.
Farm 4.0: innovative smart dairy technologies and their applications as tools for welfare assessment in dairy cattle
Authors: Azarpajouh S. , Calderón Díaz J.A. , Bueso Quan S. , Taheri H. 
Published: July 2021

Abstract
The growing world population has increased the demand for meat and milk products and has led to a rapid growth in the scale of cattle enterprises globally. As a result, livestock production would intensify even more with farmers aiming to maximize output per animal unit and it would lower the stockperson per animal ratio. This will result in less time available to monitor and manage individual animals properly, jeopardizing animal health and welfare. The recent advancement in technological and engineering tools and materials such as advanced sensors and sensing devices, and data processing and machine learning methods provide effective tools for the dairy industry to control qualitative and quantitative parameters related to dairy cattle health and welfare. This review paper will (a) explain smart dairy technologies, (b) describe on-farm cattle welfare assessment, and (c) discuss sensors applied in automatic cattle welfare assessment.
‘Schoolies Week’ on the Gold Coast, Australia
Authors: Pathirana Madura , Scott Noel 
Published: July 2021

Abstract

‘Schoolies Week’ on the Gold Coast, Australia, is an annual celebration by students completing high school. These 17–18-year-olds want to celebrate their freedom and the completion of an important stage of their lives. For some students this may be their first time away from home with their friends. For most students it is a time of celebration, but they are sometimes criticized for drinking alcohol, taking drugs, indulging in underage sex and high-spirits partying. This may cause problems for residents and other tourists. The newspaper coverage of Schoolies Week is mostly negative and detracts from the destination’s image. After some years grappling with Schoolies Week, the Queensland State Government intervened to provide a safe environment for these celebrations. They created several ‘diversionary’ events to provide activities for ‘schoolies’, and there is a large police presence as well as many volunteers to support those who are drugged or drunk. How do
you
think Schoolies Week should be managed?

Effect of auxiliary gas injection on the operation of a Hall current plasma accelerator
Authors: Karadag Burak 
Published: July 2021

Abstract
Optimization of magnetic and electric fields has been central concern for the design of a Hall current plasma accelerator since its inception decades ago. However, neutral flow dynamics in the discharge channel may have as much impact on the accelerator performance, operation stability and lifetime as the magnetic and electric fields due to its strong coupling with plasma properties. In this article, auxiliary gas injection is numerically studied for a low-power accelerator using a two-dimensional fully kinetic particle-in-cell code. Gas injection through the discharge channel sidewalls increases lifetime of the accelerator, but also degrades thrust performance suggesting that there is an optimum gas injection ratio. Although reduction in the maximum erosion rate is substantially lower than that predicted by a two-dimensional hybrid model for a high-power accelerator [14], extension of lifetime by approximately 20% appears to be possible with little impact (2%) on the thrust. The anode efficiency analysis supported by the simulated plasma properties clarifies that reduction in voltage utilization is the main cause of the observed alterations in the plasma properties and thrust performance deterioration.
Detecting and classifying neurotransmitter signals from ultra-high sensitivity PET data: the future of molecular brain imaging
Authors: Liu Heather , Morris Evan D 
Published: July 2021

Abstract
Efforts to build the next generation of brain PET scanners are underway. It is expected that a new scanner (NS) will offer an order-of-magnitude improvement in sensitivity to counts compared to the current state-of-the-art, Siemens HRRT. Our goal was to explore the use of the anticipated increased sensitivity in combination with the linear-parametric neurotransmitter PET (lp-ntPET) model to improve detection and classification of transient dopamine (DA) signals. We simulated striatal [11C]raclopride PET data to be acquired on a future NS which will offer ten times the sensitivity of the HRRT. The simulated PET curves included the effects of DA signals that varied in start-times, peak-times, and amplitudes. We assessed the detection sensitivity of lp-ntPET to various shapes of DA signal. We evaluated classification thresholds for their ability to separate ‘early’- versus ‘late’-peaking, and ‘low’- versus ‘high’-amplitude events in a 4D phantom. To further refine the characterization of DA signals, we developed a weighted k-nearest neighbors (wkNN) algorithm to incorporate information from the neighborhood around each voxel to reclassify it, with a level of certainty. Our findings indicate that the NS would expand the range of detectable neurotransmitter events to 72%, compared to the HRRT (31%). Application of wkNN augmented the detection sensitivity to DA signals in simulated NS data to 92%. This work demonstrates that the ultra-high sensitivity expected from a new generation of brain PET scanner, combined with a novel classification algorithm, will make it possible to accurately detect and classify short-lived DA signals in the brain based on their amplitude and timing.
Photonic spin Hall effect and terahertz gas sensor via InSb-supported long-range surface plasmon resonance
Authors: Cheng Jie , Wang Gaojun , Dong Peng , Liu Dapeng , Chi Fengfeng , Liu Shengli 
Published: July 2021

Abstract
The photonic spin Hall effect (SHE), featured by a spin-dependent transverse shift of left- and right-handed circularly polarized light, holds great potential for applications in optical sensors, precise metrology and nanophotonic devices. In this paper, we present the significant enhancement of photonic SHE in the terahertz range by considering the InSb-supported long-range surface plasmon resonance (LRSPR) effect. The influences of the InSb/ENZ layer thickness and temperature on the photonic SHE were investigated. With the optimal structural parameters and temperature, the maximal spin shift of the horizontal polarization light can reach up to 2.68 mm. Moreover, the spin shift is very sensitive to the refractive index change of gas, and thus a terahertz gas sensing device with a superior intensity sensitivity of 2.5 × 105 μm/RIU is proposed. These findings provide an effective method to enhance the photonic SHE in the terahertz range and therefore offer the opportunity for developing the terahertz optical sensors based on photonic SHE.
Effects of the velocity on the reversible-irreversible transition in a periodically sheared vortex system
Authors: Miyagawa K , Maegochi S , Ienaga K , Kaneko S , Okuma S 
Published: July 2021

Abstract
A reversible-irreversible transition (RIT) is studied using a periodically-driven vortex system in an amorphous film with random pinning that causes local shear, as a function of shear amplitude d. The relaxation time to reach the steady state exhibits a power-law divergence at a threshold value dc
with critical exponents in agreement with the values predicted for an absorbing phase transition in the two-dimensional (2D) directed-percolation (DP) universality class. In our previous work, the experiment was conducted at relatively high frequency f, giving rise to a large mean vortex velocity v. Here we use lower f to study the effects of reduced v and increased dynamic pinning on the RIT. The results show that the critical behavior of RIT stays essentially unchanged, while we find a trend for dc
to increase with decreasing v. We will propose a possible model to qualitatively explain this unexpected result.

Abstract
Effects of three kinds of columnar defects in NbSe2 single crystals introduced by 320 MeV Au irradiation with a dose equivalent matching field B
Φ up to 4 T were studied. Through the magnetization measurement using a SQUID magnetometer, two pronounced peak effects in the external field dependence of critical current density (J
c) were observed in crystals introduced with splayed and tilted columnar defects. In crystals with splayed columnar defects, J
c at the peak field reaches the maximum for splay angle θ
CD = ±10°, which is a little different from that found in YBa2Cu3O7 and iron-based superconductors, where optimal θ
CD is equal to ±5°.

)Fe2As2 close to the optimal composition of x ≈ 0.4, and have characterized normal state and superconducting properties for pristine and proton irradiated samples. The highest Tc
was found to be ∼36.6 K for pristine samples. A maximum critical current density of 12 MA/cm2 was achieved in a proton irradiated sample, which is comparable to that in irradiated (Ba0.6K0.4) Fe2As2. Twin boundaries were observed optically in both non-doped and under-doped samples. We also attempted local magnetic field measurements induced by transport current in a sample with twin boundaries for future exploration of nematic states in different regions of doping.
Study on Novel Jointing Technique of Soldered-stacked HTS Wires

Published: July 2021

Abstract
In high temperature superconducting (HTS) applications, joining two HTS wires is considered as an essential process for extending the available length. Many soldering and diffusion joints have been designed in recent years, but these joints mainly focused on joining two HTS virgin tapes with 4mm width and 0.15mm thickness. As for the recently developed soldered-stacked (SS) HTS wire, it does not have applicable methods of joining. In this paper, we proposed a novel technique to join two SS wires by soldering and stacking, and measured the joint resistance to demonstrate its feasibility of engineering. First, we join separate layers in SS wires using spot-welding machine. Second, we coat these layers in the solder bath. This method allows making joints and manufacturing SS wires simultaneously. This work will introduce the specification of this jointing method for SS wire, and the related experimental results will provide a reference for the SS wire joint fabrication in the future.
