Abstract
Objective Blood blister–like aneurysms (BBAs) of the internal carotid artery (ICA) are challenging to treat. We assessed the clinical and radiologic outcomes in patients with ruptured BBAs of the ICA treated with wrap-clipping.
Methods From November 2016 to January 2020, the clinical and radiologic data of patients with subarachnoid hemorrhage (SAH) caused by ICA BBAs who underwent wrap-clipping were retrospectively analyzed. The clinical outcomes were evaluated according to the modified Rankin Scale (mRS). Radiologic follow-up examinations included digital subtraction angiography (DSA), computed tomography angiography (CTA), and magnetic resonance angiography (MRA).
Results Seven patients were enrolled in this study. All BBAs were wrap-clipped successfully, including two BBAs that exhibited intraoperative bleeding and required balloon-assistance during surgery. All patients had favorable clinical outcomes during follow-up. Among the six patients who completed the radiologic follow-up visit, one patient presented ICA occlusion at the 6-month DSA follow-up, but no neurologic dysfunction was noted. We did not observe the progression of ICA stenosis in other patients.
Conclusion All BBAs in this study were wrap-clipped successfully and completely occluded. Wrap-clipping is effective for BBAs of the ICA and has favorable clinical outcomes. A multicenter study with a large sample size and a longer radiologic follow-up is necessary.

Abstract
Objective To assess maternal serum levels of vitamin D in fetuses appropriate for gestational age (AGA), small for gestational age (SGA), and with fetal growth restriction (FGR) according to estimated fetal weight (EFW).
Methods This cross-sectional study included 87 pregnant women between 26 and 36 weeks of gestation: 38 in the AGA group, 24 in the SGA group, and 25 in the FGR group. Maternal serum vitamin D levels were assessed using the chemiluminescence method. The Fisher exact test was used to compare the results between the groups.
Results The mean ± standard deviation (SD) of maternal age (years) and body mass index (kg/m2) in the AGA, SGA, and FGR groups were 25.26 ± 8.40 / 26.57 ± 4.37; 25.04 ± 8.44 / 26.09 ± 3.94; and 25.48 ± 7.52 / 26.24 ± 4.66, respectively (p > 0.05). The maternal serum vitamin D levels (mean ± SD) of the AGA, SGA, and FGR groups were 22.47 ± 8.35 ng/mL, 24.80 ± 10.76 ng/mL, and 23.61 ± 9.98 ng/mL, respectively, but without significant differences between the groups (p = 0.672).
Conclusion Maternal serum vitamin D levels did not present significant differences among pregnant women with AGA, SGA, or FGR fetuses between 26 and 36 weeks of gestation according to EFW.

Published: November 2021

AbstractPituitary gland metastases are very rare. Most patients with pituitary gland metastases are asymptomatic; therefore, most cases of this disease are diagnosed during autopsies. Moreover, the four most common primary tumors that metastasize to the pituitary gland are breast, lung, thyroid, and renal carcinomas. We present a very rare case of pituitary metastasis of spindle cell rhabdomyosarcoma (RMS). Our patient presented with headache, visual disorder, panhypopituitarism, and diabetes insipidus. Due to tumor expansion, resection was not possible, so diagnosis was confirmed by biopsy, and chemotherapy and irradiation were administered. Our patient showed widespread spindle cell RMS, which harbors a mutation of myogenic differentiation 1 (MYOD1) and is associated with a poor prognosis. Even high-risk patients can show a remission after chemotherapy and irradiation. In the cases with indistinct lesions in the sella region, pituitary metastasis should always be considered.

Published: November 2021

AbstractSinus pericranii (SP) are abnormal vascular connections between extracranial scalp venous channels and intracranial dural sinuses. This vascular abnormality rarely results in significant sequelae, but in select cases, it can be symptomatic. We describe the case of a 7-year-old girl with an SP who experienced intermittent visual, motor, and sensory symptoms not previously described in the literature. Her symptoms resolved after surgical treatment of the SP. We propose a mechanism for her symptoms and the rationale for the role of neurosurgical intervention along with a review of the literature.

Abstract
Objective To analyze the scientific production regarding maternal folic acid (FA) supplementation and its relationship with autistic spectrum disorder (ASD).
Data Sources We performed unrestricted electronic searches in the BIREME virtual bank, Virtual Health Library (VHL) and Medical Literature Analysis and Retrieval System Online (MEDLINE/PubMed) databases.
Selection of Studies For sample selection, articles that met the proposed objectives were included, published in English, Spanish and Portuguese, the use of Health Sciences Descriptors (DeCS): autistic OR autism AND autism spectrum disorder AND folic acid, AND, with the use of the Medical Subject Headings (MeSH): autistic OR autism AND autistic spectrum disorder AND folic acid.
Data Collection Data extraction was performed by the reviewers with a preestablished data collection formulary.
Data Synthesis The Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) was used based on a checklist with 27 items and a 4-step flowchart.
Results A total of 384 articles was found by the search strategies, of which 17 were eligible following the pre-established criteria. The main findings of the present review point to maternal FA supplementation in the pre-conception period and beginning of pregnancy as a protective effect in relation to ASD, which should be indicated in this period as prevention to the problem.
Conclusion According to the research analyzed, more studies are necessary to know its effects on pregnancy, since the consumption of excessive FA may not be innocuous.

Abstract
Background Pregnancy is an immunocompromised state and, for this reason, a pregnant woman is at a higher risk of getting infected as compared with a healthy individual. There is limited data available regarding the impact of COVD-19 on pregnancy; however, the case of miscarriage due to placental infection caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in second trimester has already been reported.
Methods We searched for all published articles in PubMed, Science Direct, Cochrane, Scopus, and Embase. The literature search produced 167 relevant publications; 67 manuscripts were further excluded because they did not satisfy our inclusion criteria. Out of the remaining 100 articles, 78 were excluded after full text screening. Therefore, a total of 22 articles were eligible for review in our study.
Results Overall, these 22 studies included a total of 7,034 participants: 2,689 (38.23%) SARS-CoV-2 positive pregnant women, of which 2,578 (95.87%) were laboratory confirmed and 111 (4.13%) were clinically diagnosed. Among the positive patients, there were 174 (6.47%) cases of abortion, of them 168 (96.55%) were spontaneous abortions and 6 (3.45%) were missed. Most patients either reported mild symptoms of fever, cough, fatigue, and anosmia or they presented asymptomatic.
Conclusion Additional investigation and rigorous research are warranted to confirm placental pathology mechanisms concerning COVID-19 to protect maternal and fetal health.
Practice Patterns for the Acceptance of Medically Complex Living Kidney Donors with Hematuria, Sickle Cell Trait, Smoking, Illegal Drug Use, or Urological Issues: A Multinational Survey

Published: November 2021

Abstract
Background To review the practice patterns for the acceptance of medically complex living kidney donors (MCLKD) among the transplant providers of the international transplant community.
Methods We distributed a survey globally, through major international transplantation societies, among nephrologists and transplant surgeons (TS). The survey contained questions regarding potential donors with microscopic hematuria, sickle cell trait, renal cysts, kidney stones, smoking, or illegal drug use.
Results There were 239 respondents from 29 countries, including nephrologists (42%) and TS (58%). Although most respondents would investigate microscopic hematuria, one-third of them indicated they would decline these potential donors without investigation. Interestingly, most respondents accepted heavy smokers, intermittent illegal drug users (with advice to quit), and those with incidentally identified kidney stones, remote history of renal colic or simple renal cysts. We found multiple areas of consensus in practice with some interesting differences between nephrologists and TS.
Conclusions This survey highlights the practice patterns of the acceptance of MCLKDs among the international community. In the absence of clear guidelines, this survey provides additional information to counsel kidney donors with microscopic hematuria, sickle cell trait, renal cysts, kidney stones, heavy smoking, or illegal drug use.
Boosting promotes advantageous risk-taking

Published: November 2021

AbstractDue to the prevalence and importance of choices with uncertain outcomes, it is essential to establish what interventions improve risky decision-making, how they work, and for whom. Two types of low-intensity behavioural interventions are promising candidates: nudges and boosts. Nudges guide people to better decisions by altering how a choice is presented, without restricting any options or modifying the underlying payoff matrix. Boosts, on the other hand, teach people decision strategies that focus their attention on key aspects of the choice, which allows them to make more informed decisions. A recent study compared these two types of interventions and found that boosts worked better for risky choices aimed at maximising gains, whereas nudges worked best for choices aimed at minimising losses. Though intriguing, these findings could not be easily interpreted because of a limitation in the items used. Here we replicate that study, with an extended item set. We find that boosts work by promoting risk-taking when it is beneficial, whereas nudges have a consistent (lesser) impact, regardless of whether risk-taking is beneficial or not. These results suggest that researchers and policymakers should consider the base rate risk propensity of the target population when designing decision-support systems.
Research on the conduction process of laser triggered vacuum switch
Authors: Shi Rui , Kong Lingkai , Li Jie 
Published: November 2021

In this paper, the conduction process of the Laser Triggered Vacuum Switch (LTVS) is studied. First, the velocity, density, and temperature of the initial plasma in the LTVS are simulated using COMSOL Multiphysics software. It is found that the generation and development of the initial plasma are at the ns level. Second, the pre-breakdown current test circuit of the LTVS is established. It is found that when the applied voltage at both ends of the switch is 60 V, the multi-rod LTVS is successfully conducted, and then, the current becomes the conduction current and the voltage applied at both ends of the switch decreases significantly. Finally, the images of the LTVS vacuum arc are taken. With the increase in laser energy, the more abundant the initial plasma is, the lower the required gap voltage is. When the current increases to a certain value, the vacuum arc appears in multiple discharge channels, which makes the arc have a diffusion morphology. It is found that the current withstand capacity of a single channel is about 50 kA. As the multi-rod LTVS has three channels, its current withstand capacity can reach 150 kA.

Published: November 2021

In BaTiO3 single crystals, we observed a strain-driven phase transition from the tetragonal phase to the tetragonal-orthorhombic phase boundary which can be introduced by slow cycling compressions (a loading of up to 0.5 GPa, strain rate of 10−4 s−1, and 100 cycles) at room temperature. Different from the well-known tetragonal to cubic phase transition under stress (∼2 GPa), it only takes place locally around bent 90° domain walls. The inhomogeneous local stress and electrical fields as well as the mobile point defect pinning effect contribute to the phase re-entrance. Through comparison experiments by in situ synchrotron x-ray diffraction, Raman scattering, and (scanning) transmission electron microscopy, we explored the phase transition mechanism. Based on that, we developed a mechanical method to obtain well-stabilized high-density thermotropic phase boundary structures (with tetragonal, orthorhombic, and bridging monoclinic phases) in BaTiO3 for potential applications.
Influence of the physical properties of pumice and biochar amendments on the soil’s mobile and immobile water: implications for use in saline environments
Authors: Kong Chao , Camps-Arbestain Marta , Clothier Brent 
Published: November 2021

Context Biochar and pumice have potential to improve soil water retention and mitigate salinity. However, little is known about their effect on salt transport in sandy soils. Aims We investigated the influence of the porosity and pore size distribution of soil amendments with pumice and biochar on the mobile water content of a New Zealand sandy soil. Methods Pumice and biochar (1.5-cm, 3-cm and 6-cm in diameter, Ø) were characterised using scanning electron microscope technology. The fraction of mobile water present in these amendments, previously added to a sandy soil at different application rates and particle sizes, was determined using a tracer (Na+) technique. Key results (1) Pumice exhibited a wider pore-size span than biochar; and (2) both materials had a predominance of pores with Ø < 30 μm; but (3) the total porosity in pumice and biochar was not significantly different; (4) pumice had a significantly larger (P < 0.05) mean absolute micro-scale porosity than biochar; and (5) a significantly greater (P < 0.05) relative resident Na+ concentration than biochar, irrespective of the particle size. Conclusions These results reflect a larger fraction of the mobile water in pumice than that of biochar under near-saturated conditions, irrespective of the biochar particle size; and this increased as the pumice particle size increased. Implications While both materials are expected to contribute to water retention and thus might alleviate salt-stress by diluting salt concentration, pumice may perform better than this specific biochar on improving the retention of plant-available water.
Gravel-associated organic material is important to quantify soil carbon and nitrogen stocks to depth in an agricultural cropping soil
Authors: Kirkby Clive A. , Kirkegaard John A. , Richardson Alan E. 
Published: November 2021

Context Gravel is a common constituent in soil and is routinely excluded when estimating soil carbon (C) and nitrogen (N) stocks. Aims We investigated the contribution that the gravel fraction (>2 mm) makes to C and N stocks in an agricultural soil. Methods The amount of gravel and the C and N content of gravel-associated organic matter (OM) was assessed to 180 cm in a long-term cropping soil with differing nutrient treatments. Key results Gravel-associated C and N accounted for ∼5% of the total C and N stocks in the upper layers (0–30 cm) of soil and up to 40% below 100 cm. The C:N ratio of the gravel-associated OM was similar to that in fine earth fraction (FEF) soil, with C:N ratio of ∼13 in surface layers to ∼8 at depth. Conclusions We estimated that 19% and 23% of the total stock of C and N, respectively, were associated with gravel over the whole soil profile. In the two nutrient treatments, with differing C and N stocks in the FEF, gravel-associated OM accounted for 9.3–10.6 t C ha−1 and 1.1–1.3 t N ha−1. Implications Our work highlights the significance of gravel in contributing to soil OM and the importance of sampling to depth to estimate soil C and N stocks. Importantly, disregard of the gravel fraction results in an underestimation of total soil C and N, which has implications for the accounting of C in agricultural soils and for the development of strategies to sequester soil C.
Focus fronting vs. wh-movement
Authors: Cruschina Silvio 
Published: November 2021

Abstract
It is commonly held that focus fronting exhibits similar properties to wh-movement. The syntactic parallelism between the two types of movement has been supported by the semantic analyses of wh-questions that assume that when wh-words function as interrogative operators, they are inherently focal. The main goal of this paper is to challenge this highly attractive picture of the relationship between wh-words, focus, and movement, and to claim that wh-phrases are not inherently focal. The results of a prosodic production experiment on the distribution of the nuclear pitch accent in Sardinian wh-questions, together with the syntactic properties related to the asymmetry between direct and indirect wh-questions, form the empirical basis of this study.
Differential object marking and scale reversals
Authors: Irimia Monica Alexandrina , Pineda Anna 
Published: November 2021

Abstract
This paper focuses on some problematic aspects of the diachrony of differential object marking in Old Catalan and Old Romanian (11th to 17th centuries). Corpus data from both languages reveal two unexpected facts: (i) there is a prominence of 3rd person to the exclusion of 1st and 2nd person, contrary to what the Animacy/Person scale would predict; (ii) differential marking appears to be present on nominals (especially proper names), to the exclusion of pronouns, this time contrary to the Specificity/Definiteness Scale. The account we propose for these types of scale reversals builds on the idea that languages can have more than one differential object marking strategy, as well as more than one type of structure for pronouns and animate nominals. Moreover, the co-existence of various mechanisms for nominal licensing can explain why, in some instances, classes lower down the hierarchies can get signaled to the exclusion of higher ones.
A Grammar of Authority?
Authors: Gerstenberg Annette , Skupien-Dekens Carine 
Published: November 2021

AbstractDirective Speech Acts (dsas) are a major feature of historical pragmatics, specifically in research on historical (im)politeness. However, for Classical French, there is a lack of research on related phenomena. In our contribution, we present two recently constructed corpora covering the period of Classical French,sermoandapwcf.We present these corpora in terms of their genre characteristics on a communicative–functional and socio-pragmatic level. Based on the observation that, both insermoandapwcf,dsas frequently occur together with terms of address, we analyse and manually code a sample based on this co-occurrence, and we compare the results with regard to special features in the individual corpora. The emerging patterns show a clear correspondence between socio-pragmatic factors and the linguistic means used to realisedsas. We propose that these results can be interpreted as signs of an underlying “grammar of authority”.
L2 acquisition of definiteness in Japanese floating numeral quantifiers
Authors: Kume Keisuke , Marsden Heather 
Published: November 2021

Abstract
This study investigates the second language (L2) acquisition of a constraint on definiteness in Japanese floating numeral quantifiers (NQs) by native English and Korean speakers. The constraint arises because of the specific structural relation between a floating NQ and its associated noun, resulting in an obligatorily indefinite interpretation. The indirect – or, covert – encoding of definiteness in this structure allows investigation of predictions based on the cline of difficulty proposed by Cho and Slabakova (2014), whereby L2 acquisition of a covert property may be facilitated if the first language (L1) expresses the relevant feature overtly. English is such a language, having overt morphology to express definiteness, whereas Korean has floating NQs that are obligatorily, and covertly, indefinite, as in Japanese. Sensitivity to definiteness in Japanese floating NQs was measured using an acceptability judgement task. Although both L1-Korean and L1-English speakers of Japanese showed sensitivity to the constraint at group level, follow-up analyses suggested that the Korean group had more consistent knowledge. We argue that the complexity of the acquisition task – which was greater for the English-speakers than the Korean-speakers – played a bigger role in attainment than overt versus covert encoding of the relevant feature in the L1.
Research on optimal path planning of indoor robot based on wireless sensor
Authors: Wang Shouwen 
Published: November 2021

Abstract
Based on the work tasks and positioning characteristics of indoor robots, the environment is divided into grids, and wireless sensors are used to detect obstacles, and the density of obstacles in each grid is given. At the same time, the path planning algorithm is combined to realize the optimal path planning of indoor robot. The simulation results show that the wireless sensor network can realize the obstacle density detection, so that the robot can achieve fast optimal path planning and reach the target point.
