Abstract
Background There is limited data available regarding the prevalence of intracranial arterial stenosis (ICAS) among acute ischemic stroke (AIS) patients in Brazil and Latin America.
Objective The present study sought to investigate the frequency and predictors of ICAS among patients with AIS or transient ischemic attack (TIA) in a Brazilian center, with transcranial color-coded duplex sonography (TCCS) technique.
Methods Consecutive AIS and TIA patients, admitted to an academic public comprehensive stroke center in Brazil from February to December 2014, evaluated by TCCS were prospectively selected. Vascular narrowings > 50% were considered as ICAS, based on ultrasound criteria previously defined in the literature.
Results We assessed 170 consecutive patients with AIS or TIA, of whom 27 (15.9%) were excluded due to an inadequate transtemporal acoustic bone window. We confirmed ICAS in 55 patients (38.5%). The most common location was the proximal segment of the middle cerebral artery (28.2%), followed by the vertebral (15.4%), posterior cerebral (13.6%), terminal internal carotid (9.1%) and basilar (8.2%) arteries. On multivariate models adjusting for potential confounders, systolic blood pressure (OR: 1.03, 95%CI: 1.01–1.04; p = 0.008) was independently associated with ICAS.
Conclusion We found significant ICAS in approximately ⅓ of patients admitted with symptoms of AIS or TIA in a public tertiary academic stroke center in Brazil. The TCCS is an accessible and noninvasive technique that can be used to investigate the presence of moderate and severe ICAS, especially in patients who cannot be exposed to more invasive exams, such as the use of intravenous contrast agents.

Abstract
Introduction Curculigo orchioides Gaertn, an endangered medicinal plant, possesses a bioactive compound known as curculigoside (phenolic glycoside) in addition to other phenolic compounds. Curculigoside has multifunctional pharmacological properties including antioxidant and anti-inflammatory. Advances in plant tissue culture provide us with tools for the in vitro propagation of medicinal plants in addition to a well-founded system to enhance pharmacologically bioactive compounds through the use of elicitors.
Objective The study evaluates the effect of exogenous application of salicylic acid (SA) and polyethylene glycol 6000 (PEG 6000) to in vitro cultures of C. orchioides for enhanced curculigoside, phenolic compounds production followed by an increase in antioxidant activity (AA).
Method Eight-week-old subcultured plants grown in one-fourth strength Murashige and Skoog media were subjected to elicitors treatment. SA (10, 100, and 1,000 ppm) and a PEG 6000 (1,000, 5,000, and 10,000 ppm) were used as elicitors for a period of 1, 2, and 4 weeks. Plants without treatment were considered as control. The treated plants were subjected to 80% acetone solvent for efficient phenolic extract preparation. High-performance liquid chromatography was used for the analysis of curculigoside content (CC), and total phenolic content (TPC) was determined using the Folin–Ciocalteu colorimetric method. AA was evaluated by 1,1-diphenyl-2-picrylhydrazyl assay.
Results SA treatment increased CC, TPC, and biological activity of AA properties compared to the control, with the maximum value observed at 10 ppm treatment after week 1 elicitation. CC, TPC, and AA gradually decreased after week 2 elicitation, and the lowest values were observed after week 4 elicitation. In the PEG 6000 treatment, 10,000 ppm elicited the highest CC and TPC, with the maximum AA observed after week 2 elicitation. The treatment also elicited higher CC, TPC, and AA in both the 1st and 4th weeks compared to the control.
Conclusion SA and PEG 6000 successfully enhanced CC, TPC, and improved AA in C. orchioides in vitro. The study also offers insightful information for the neutraceutical, cosmeceutical, and pharmaceutical industries about how to potentially manipulate medicinal plants in vitro to increase the synthesis of bioactive compounds.

Published: August 2024

Using modern databases, the behavior of the isothermal compressibility coefficient −(∂V/∂P)T = VβT of water in the liquid state near its specific temperature of θ = 42.2 ± 0.2 °C was analyzed. The applicability of the principle of corresponding states in a wide range of thermodynamic parameters of water has been confirmed, excluding the area of water anomalies. The following anomalies of the physical–chemical properties of water were observed: (a) the temperature of θ = 42.2 ± 0.2 °C was found at which the entropy contribution to the isothermal compressibility coefficient of water changed its sign and became positive below this temperature; (b) the temperature of θ = 28.8 ± 0.2 °C was found at which the energy contribution to the isothermal compressibility coefficient of water changed its sign and became negative below this temperature; and (c) the temperature of θ = 17.6 ± 0.2 °C was found at which the energy and entropy contributions to the isothermal compressibility coefficient of water were equal. The entropy contribution to the isothermal compressibility coefficient, according to the two-structure model of water, can be associated with the existence of an “expanded” low-density water structure of hydrogen bonds, the role of which increases with decreasing temperature. We associate the energy contribution to the isothermal compressibility coefficient with the “collapsed” high-density water structure of hydrogen bonds, the role of which in the field of thermodynamic anomalies of water decreases as the temperature decreases.

Objective This study aimed to compare the relative physical recovery and symptoms after SARS-CoV-2 infection between groups confirmed positive or negative to early strains of COVID-19. Methods A prospective, longitudinal cohort study compared outcomes of metropolitan adults polymerase chain reaction-tested for COVID-19 between March and November 2020 in Western Australia. Control matching was attempted: inpatients (gender, age) and ambulatory clinic (gender, age, asthma, chronic pulmonary disease). One-year follow-up involved three repeated measures: physical function (grip strength and 1-min sit-to-stand) and patient-reported outcomes (Fatigue Severity Scale, modified Medical Research Council dyspnoea scale and Euroqol-5D-5L). Results Three hundred and forty-four participants were recruited (154 COVID+, age 54 ± 18 years, 75 females [49%]); 190 COVID−, age 52 ± 16 years, 67 females [35%]) prior to national vaccination roll-out. No between-group differences in physical function measures were evident at any time point. Fatigue (OR 6.62, 95% CI 2.74–15.97) and dyspnoea (OR 2.21, 95% CI 1.14–4.30) were higher in the COVID+ group at second assessment (T2). On Euroqol-5D-5L, no between-group differences were evident in the physical function domains of self-care, mobility or usual activities at any time point. However, COVID+ participants were less likely to report an absence of anxiety or depression symptoms at T2 (OR 0.41, 95% CI 0.19–0.89). Conclusions Neither statistical nor clinically meaningful differences in physical function were evident between COVID+ and COVID− participants to 12-months after acute illness. Symptoms of fatigue, dyspnoea, anxiety or depression were more prevalent in the COVID+ group til ~8 months after illness with between-group differences no longer evident at 1 year.

During the past two decades, the phylogenetic relationships and higher-level classification of the subfamily Rogadinae have received relevant contributions based on Sanger, mitogenome and genome-wide nuclear DNA sequence data. These studies have helped to update the circumscription and tribal classification of this subfamily, with six tribes currently recognised (Aleiodini, Betylobraconini, Clinocentrini, Rogadini, Stiropiini and Yeliconini). The tribal relationships within Rogadinae, however, are yet to be fully resolved, including the status of tribe Facitorini, previously regarded as betylobraconine, with respect to the members of Yeliconini. We conducted a phylogenomic analysis among the tribes of Rogadinae based on genomic ultraconserved element (UCE) data and extensive taxon sampling including three undescribed genera of uncertain tribal placement. Our almost fully supported estimate of phylogeny confirmed the basal position of Rogadini within the subfamily and a Facitorini clade (Yeliconini + Aleiodini) that led us to propose the former group as a valid rogadine tribe (Facitorini stat. res.). Stiropiini, however, was recovered for the first time as sister to the remaining rogadine tribes except Rogadini, and Clinocentrini as sister to a clade with Betylobraconini + the three undescribed genera. The relationships recovered and morphological examination of the material included led us to place the latter three new genera and recently described genus Gondwanocentrus within a new rogadine tribe, Gondwanocentrini Shimbori & Zaldívar-Riverón trib. nov. We described these genera (Ghibli Shimbori & Zaldívar-Riverón gen. nov., Racionais Shimbori & Zaldívar-Riverón gen. nov. and Soraya Shimbori gen. nov.) with two or three new species each (G. miyazakii Shimbori & Zaldívar-Riverón sp. nov., G. totoro Shimbori & Zaldívar-Riverón sp. nov., R. brunus Shimbori & Zaldívar-Riverón sp. nov., R. kaelejay Shimbori & Zaldívar-Riverón sp. nov., R. superstes Shimbori & Zaldívar-Riverón sp. nov., S. alencarae Shimbori sp. nov. and S. venus Shimbori & Zaldívar-Riverón sp. nov.). A new species of Facitorini, Jannya pasargadae Gadelha & Shimbori sp. nov., is also described. Our newly proposed classification expands the number of tribes and genera within Rogadinae to 8 and 66 respectively. ZooBank: urn:lsid:zoobank.org:pub:51951C78-069A-4D8B-B5F0-7EBD4D9D21CE
Availability of phosphorus and nitrogen from modified mono-ammonium phosphate (MAP) fertiliser compounds
Authors: McLachlan Jonathan W. , English Peter W. , Flavel Richard J. , Guppy Chris N. 
Published: August 2024

Moderating nutrient release to match plant requirements more closely can improve nutrient use efficiency. The formation of lower-solubility ammonium salts may be a simple and cost-effective way to slow the release of nitrogen (N) from fertiliser sources. Several modified mono-ammonium phosphate (MAP) fertiliser compounds were prepared by adding magnesium silicate to regular MAP fertiliser and reconstituting the granules. This process results in the formation of schertelite that may potentially slow the release of both N and phosphate to soil solution. These modified MAP fertiliser compounds include more citrate-soluble N and phosphorus (P) than standard MAP fertiliser. The fertiliser compounds were added to a P-responsive soil and barley plants were grown for 5 weeks to investigate shoot yield responses to nutrient availability of the modified MAP fertiliser compounds. Reverse dilution tracing techniques were also used to compare the fertiliser solubility and P availability of the modified MAP fertiliser compounds with regular MAP fertiliser. Barley (Hordeum vulgare) plants recovered P equally and efficiently over 5 weeks of growth in the P-responsive soil, suggesting that the fertiliser compounds were sufficiently soluble to meet plant requirements and that phosphate release was not slowed by the formation of schertelite. However, shoot yields were generally lower when the barley plants were grown with the modified MAP fertiliser compounds compared to standard MAP fertiliser. This reduced growth was likely due to decreased N availability through a slower release of N, thus further research is warranted to determine the potential for these products to improve N use efficiency.
Transplanted Brazilian Portuguese in Japan

Published: August 2024

Abstract
This paper explores an emerging Brazilian Portuguese koiné spoken among Brazilian-dominant Latin American
immigrants in Japan’s Greater Tokyo Area. It examines Strong-R (onset /r/) realizations by 79 speakers in the context of dialect
and language contact within the diasporic setting. The results highlight (a) levelling and focussing towards [h] as a result of
koineization and (b) early stages of the adoption of [ɸ], a xenolectal feature, resulting from contact with Japanese. The external
and internal motivations for change towards [h] are identified as local and supralocal levelling
and drift. The transition to [ɸ], and its linguistic and social embedding, are discussed in terms of acquisition order, the
structure of the Japanese kana syllabary, and speakers’ social networks. The conclusion emphasizes the importance
for koiné genesis of input dialects, ongoing language change in the homeland, the social meaning of variants in both
pre- and post-contact societies, and speakers’ social networks and mobilities.
The syntactic and semantic promenade of the Spanish absolute construction along the Communicative
Continuum
Authors: Molenaers Marie 
Published: August 2024

Abstract
This paper investigates the diachronically changing syntactic and semantic status of the Spanish Absolute
Construction (AC) on the Communicative Continuum (Koch & Oesterreicher 1990 [2011])
in a corpus of 15th- to 18th-century translations from Latin. Previous research has already demonstrated that the 15th-century
preclassical Spanish AC evolved from a highly formal past participial Latin calque in the realm of Communicative Distance to an
entrenched gerundial absolute in the 18th century, positioned slightly further from the Communicative Distance pole (Del Rey Quesada 2018, 2021, Molenaers 2023).
This study highlights that, besides the altering predicate, other characteristics enhanced the AC’s progression along the
Continuum, including one syntactic (non-augmentation) and two semantic (non-adverbial, coreferential) factors. By means of clause
linkage (Raible 1992, 2001), a development
is traced to a syntactically less dense and semantically less complex gerundial AC, which displays a high frequency of the three
outlined features. Complementary analyses grounded in a functional-pragmatic theory of subordination (Cristofaro 2003) have revealed a moderate widening of the innovative AC’s clausal status beyond strict
subordination. Two language-internal evolutions, the case switch from ablative to nominative in the transition from Latin to
Spanish and priming with the gerundial unaugmented free adjunct (FA), are identified as the driving forces behind the Spanish AC’s
syntactic and semantic promenade beyond the extremes of Communicative Distance.

Abstract
The ambiguity resolution (AR) significantly enhances the accuracy of precise orbit determination (POD). There have been numerous studies of different forms of POD: double-difference (DD), single-difference (SD), and un-differenced (UD) AR methods for global navigation satellite systems (GNSS) or low earth orbit (LEO). However, challenges persist in the integrated POD (IPOD) of the GNSS and LEO at regional ground stations. These challenges include the frequent selection of dual receiver-satellite pairs in DD methods, and time-varying hardware biases in LEO receivers for UD methods. In addition, the SD AR method has not been explored in IPOD, resulting in unfixed ambiguities. In this study, we investigated the feasibility and performance enhancement of AR in the BeiDou Navigation Satellite System (BDS) and LEO IPOD under regional ground stations using simulated ground and onboard observations. First, we introduce AR models applicable to BDS and LEO IPOD and analyze the applicability of different AR models for IPOD under regional ground stations. We designed a study to utilize SD ambiguity, which eliminates the time-varying hardware bias of the LEO receiver end, to estimate the uncalibrated phase delay (UPD) of the satellite end. Furthermore, we designed the BDS-3 and LEO constellations with 24 regional ground stations in China and simulated seven days of observations. Subsequently, the narrow-lane (NL) UPD quality and AR performance were analyzed, and a solution with satisfactory stability and residual distribution was obtained, enabling the implementation of SD AR. The daily fixed rate for wide-lane ambiguities exceeded 99%, while for NL ambiguities it surpasses 86%. After fixing ambiguities, the BDS-3 orbit’s along-track and cross-track components significantly improved. Simultaneously, LEO orbit solutions improved by over 20% in all three directions. Overall, the UPD estimation model using SD ambiguities yielded satisfactory UPD results, enabling AR and significantly enhancing the orbit accuracy of GNSS and LEO.
TSMDA: intelligent fault diagnosis of rolling bearing with two stage multi-source domain adaptation

Abstract
Fault diagnosis plays a critical role in ensuring the safe operation of machinery. Multi-source domain adaptation (DA) leverages rich fault knowledge from source domains to enhance diagnostic performance on unlabeled target domains. However, most existing methods only align marginal distributions, neglecting inter-class relationships, which results in decreased performance under variable working conditions and small samples. To overcome these limitations, two stage multi-source domain adaptation (TSMDA) has been proposed for bearing fault diagnosis. Specifically, wavelet packet decomposition is applied to analyze fault information from signals. For small sample datasets, Diffusion is used to augment the dataset and serve as the source domain. Next, multi-scale features are extracted, and mutual information is computed to prevent the negative transfer. DA is divided into two stages. Firstly, multikernel maximum mean discrepancy is used to align the marginal distributions of the multi-source and target domains. Secondly, the target domain is split into subdomains based on the calculated pseudo-labels. Conditional distributions are aligned by minimizing the distance from samples to the center of the non-corresponding domain. The effectiveness of the proposed method is verified by extensive experiments on two public datasets and one experimental dataset. The results demonstrate that TSMDA has high and stable diagnostic performance and provides an effective method for practical fault diagnosis.

Abstract
In this paper, we report thermally stable photosensing using MoS2 phototransistor with a poly(methyl methacrylate) (PMMA) coating. The increase in the OFF current of the PMMA-coated MoS2 phototransistor degraded to less than 87.72% of that of the pristine MoS2 phototransistor under harsh temperature conditions (250 °C). PMMA coating on the pristine MoS2 phototransistor improved the photosensitivity and drain current stability as a function of time by 315.71% at 250 °C and 91.26% under intense negative bias temperature illumination stress (NBTIS) test (V

Published: August 2024

Abstract
To meet the ultrasonic application requirement of high power intensity and large mechanical displacement, a new theoretical method is used to study the multi-mode characteristic of the cascaded piezoelectric transducer with cone horn in this paper. Based on equivalent circuit and Kirchhoff’s law to obtain the frequency equation and vibration velocity expression of the transducer, then the resonance frequency and effective electromechanical coupling coefficient can be calculated, the velocity amplification ratio can be obtained in the meantime. This method is distinguish from traditional theoretical analysis, which avoids complex transformation of the multi-excitation sources in cascaded structure, and can calculate more performance parameters. The relationships between these performance parameters and the excitation position of the piezoelectric stack, the length and output end radius of the cone horn are analyzed and compared with the numerical simulation, and the optimized parameters of the transducer size are given. A transducer is manufactured for experimental test, the results show that the experimental value is in good agreement with theoretical calculation and finite element simulation. This work is expected to be used in the optimal analysis of the multi-mode transducer in high power ultrasonic field.
