Published: August 2023

A mononuclear 8‐coordinate Fe(II) compound, [FeII(L1)2](CF3SO3)2 (1), was prepared from the reaction of a neutral tetradentate ligand (L1=N2,N9‐dibutyl‐1,10‐phenanthroline‐2,9‐dicarboxamide) and hydrated Fe(CF3SO3)2 in MeOH. 1 could be considered as an ‘ideal’ 8‐coordinate Fe(II) compound as compared with the previously reported Fe(II) analogs, because all the terminal Fe−O bond lengths are in the normal range. The magnetic properties investigation shows that 1 exhibit field‐induced slow magnetic relaxation behavior.

Authors: Li Wenhai , Cheng Zhiling , Chen Yuan , Li Ao , Deng Lingfeng
Published: August 2023

Concurrent hash tables are one of the fundamental building blocks for cloud computing. In this paper, we introduce lock-free modifications to in-memory bucketized cuckoo hashing. We present a novel concurrent strategy in designing a lock-free hash table, called LFBCH, that paves the way towards scalability and high space efficiency. To the best of our knowledge, this is the first attempt to incorporate lock-free technology into in-memory bucketized cuckoo hashing, while still providing worst-case constant-scale lookup time and extremely high load factor. All of the operations over LFBCH, such as get, put, “kick out” and rehash, are guaranteed to be lock-free, without introducing notorious problems like false miss and duplicated key. The experimental results indicate that under mixed workloads with up to 64 threads, the throughput of LFBCH is 14%–360% higher than other popular concurrent hash tables.
Distributed Deep Multilevel Graph Partitioning
Authors: Sanders Peter , Seemaier Daniel
Published: August 2023

We describe the engineering of the distributed-memory multilevel graph partitioner . It scales to (at least) 8192 cores while achieving partitioning quality comparable to widely used sequential and shared-memory graph partitioners. In comparison, previous distributed graph partitioners scale only in more restricted scenarios and often induce a considerable quality penalty compared to non-distributed partitioners. When partitioning into a large number of blocks, they even produce infeasible solution that violate the balancing constraint. achieves its robustness by a scalable distributed implementation of the deep-multilevel scheme for graph partitioning. Crucially, this includes new algorithms for balancing during refinement and coarsening.

Published: August 2023

Abstract

In this note we revisit the homotopy-algebraic structure of oriented bosonic open-closed string field theory and we give a new compact formulation in terms of a single cyclic open-closed co-derivation which defines a single nilpotent structure describing the consistency of generic open-closed off-shell amplitudes with arbitrary number of boundaries and at arbitrary genus.
Expression of four cancer-testis antigens in TNBC indicating potential universal immunotherapeutic targets
Authors: Xiao Jie , Huang Fengli , Li Lin , Zhang Lianru , Xie Li , Liu Baorui
Published: August 2023

Objective

Immunotherapy is an attractive treatment for breast cancer. Cancer-testis antigens (CTAs) are potential targets for immunotherapy for their restricted expression. Here, we investigate the expression of CTAs in breast cancer and their value for prognosis. So as to hunt for a potential panel of CTAs for universal immunotherapeutic targets.

Material and methods

A total of 137 breast cancer tissue specimens including 51 triple-negative breast cancer (TNBC) were assessed for MAGE-A4, MAGEA1, NY-ESO-1, KK-LC-1 and PRAME expression by immunohistochemistry. The expression of PD-L1 and TILs was also calculated and correlated with the five CTAs. Clinical data were collected to evaluate the CTA’s value for prognosis. Data from the K-M plotter were used as a validation cohort.

Results

The expression of MAGE-A4, NY-ESO-1 and KK-LC-1 in TNBC was significantly higher than in non-TNBC (P = 0.012, P = 0.005, P < 0.001 respectively). 76.47% of TNBC expressed at least one of the five CTAs. Patients with positive expression of either MAGE-A4 or PRAME had a significantly extended disease-free survival (DFS). Data from the Kaplan–Meier plotter confirm our findings.

Conclusions

MAGE-A4, NY-ESO-1, PRAME and KK-LC-1 are overexpressed in breast cancer, especially in TNBC. Positive expression of MAGE-A4 or PARME may be associated with prolonged DFS. A panel of CTAs is attractive universal targets for immunotherapy.
Understanding the rationale and advantages of a traditional Mediterranean intercropping system in the nineteenth century
Authors: Díez Sanjuán Lucía , Migliorini Paola
Published: August 2023

Traditional agricultural systems in Mediterranean Europe were characterised by diversity and multifunctionality, and polycultures played a fundamental role in them. Some of these farm systems and the traditional agricultural practices linked to them have now largely disappeared, but they are increasingly recognised as a valuable source of agroecological knowledge. In this study, we seek to recover the long-lost experience from a traditional Mediterranean intercropping system that combined the cultivation of vines and cereals. Using local historical resources available for a Catalan village for the second half of the nineteenth century, we compare the characteristics and functioning of intercropping and monocultures of vines and cereals using socioeconomic and agrarian metabolism indicators, and discuss the advantages of the traditional intercropping system as an adaptation to the productive limitations of the agroecosystem (particularly in terms of soil quality and productivity, and availability of labour and draft force), but also as a peasant economy strategy that responded to a multifunctional balancing rationale. This way, this research contributes to recovering the knowledge and experience of a long-lasting traditional crop system that had been used until the second half of the twentieth century, and provides an understanding of the rationale and advantages of traditional Mediterranean crop systems beyond productivity and profit maximisation strategies.
Fuzzy clustering of financial time series based on volatility spillovers
Authors: Cerqueti Roy , D’Urso Pierpaolo , De Giovanni Livia , Mattera Raffaele , Vitale Vincenzina
Published: August 2023

In this paper we propose a framework for fuzzy clustering of time series based on directional volatility spillovers. In the case of financial time series, detecting clusters of volatility spillovers provides insights into the market structure, which can be useful to both portfolio managers and policy makers. We measure directional—i.e. “From” and “To” the others—volatility spillovers with a methodology based on the generalized forecast-error variance decomposition. Then, we propose a weighted fuzzy clustering model for grouping stocks with a similar degree of directional spillovers. By using a weighted approach, we allow the algorithm to decide which dimension of spillover is more relevant for clustering. Moreover, a robust clustering model is also proposed to alleviate the effect of possible outlier stocks. We apply the proposed clustering model for the analysis of spillover effects in the Italian stock market.

Authors: Montaser Atiat A. , El-Mahdy Mohamed Sarwat , Mahmoud Elsayed E. E. , Fouda A. S.
Published: August 2023

The antibiotic Ciprofloxacin (CIPRO) was investigated as a new inhibitor for copper corrosion in Synthetic Acid Rain Solution (SAR) utilizing Mass Loss (ML) as a chemical method, Potentiodynamic Polarization (PDP), and Electrochemical Impedance Spectroscopy (EIS) as electrochemical techniques. In the presence of 600 ppm of the antibiotic CIPRO, the protection percentage reached 90.1% according to the EIS technique. Thermodynamic adsorption and activation characteristics were evaluated and described. The CIPRO adsorption on the Cu surface in the SAR solution was physical adsorption and complied with the Langmuir isotherm. According to PDP curves, the studied medication was served as a mixed type of inhibitor. This medication prevented corrosion by adhering to the metallic surface, which was demonstrated by Atomic Force Microscopy (AFM), Scanning Electron Microscopy-Energy Dispersive X-Ray (SEM–EDX), and Fourier-Transform Infrared Spectroscopy (FTIR). Results from the Density Functional Theory (DFT) and Monte Carlo simulations (MC) complement experimental results. The inhibition efficiencies obtained via different methods are consistent with each other.

Published: August 2023

Pure zinc oxide, single-doped zinc oxide as 2 wt% of Lanthanum as (La DZ NPs), 2 wt% of Samarium (Sm DZ NPs), and 2 wt% of Strontium as (Sr DZ NPs), and tri-doped (Sm, La, Sr, T DZ NPs) were synthesized with a hydrothermal method. Additionally, these nanomaterials are used as an effective photocatalytic for the degradation of Reactive Red 43. These nanomaterials’ optical, particle size distribution, structural properties, and morphology were analyzed using X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), ultraviolet (UV) light, photoluminescence (PL), scanning electron microscopy (SEM) and energy-dispersive X-ray (XPS), transmission electron microscopy (TEM), and the point of zero charges (pHpzc). Molecular modeling simulation was calculated using density functional theory (DFT) to confirm some characterization. Moreover, these studies showed the crystal structure parameters changed with doped nanomaterials, and the experimental band gap fit theoretical calculation and demonstrated the reason for the widening of the band gap. An enhancement in the surface area of Sr DZ NPs recorded high value (SBET = 37.43 m2/g) indicated that it can be used as an efficient photocatalyst, where Sr DZ NPs showed the best photodegradation % of Reactive Red 43 dye with 93.43% compared to PZ (72.88%), La DZ NPs (52.54 3%), Sm DZ NPs (31.99%), and La, Sm, Sr T DZ NPs (20.55%). Furthermore, the pseudo-first-order kinetic model better fits the R2 values. Finally, the mechanism of degradation has been related to electronic configuration. In addition, the recyclability showed stability of nanomaterials under UV irradiation.

Optical crosstalk and other forms of light interference in pulse oximeter comparison studies
Authors: Kyriacou Panicos A.
Published: August 2023

Purpose: Pulse oximeter accuracy is important for the quality and safety of patient care. Methodological errors occurring during pulse oximeter accuracy studies can confound results. One potential source of error during pulse oximeter comparison studies is optical interference due to sensor-to-sensor crosstalk. Optical crosstalk can occur whenever pulse oximeter sensors are tested in close proximity of one another, as occurs during pulse oximeter comparison studies. Methods: This publication represents the first comprehensive review of sensor-to-sensor crosstalk and other forms of optical interference during pulse oximeter comparison studies. A review of the published literature was undertaken to elucidate the mechanism of optical crosstalk, along with other forms of optical interference, and a solution (shielding) is offered. Results: When pulse oximeter sensors are placed close to each other, as occurs during comparison studies, the red and near-infrared light used can also enter an adjacent sensor and lead to error. Pulse oximeter manufacturers have designed systems to reject some forms of optical interference, such as ambient light. However, light emanating from adjacent sensors during comparison studies can cause artifact, and this can be exacerbated by sensor malposition. Proper sensor placement and use of optical shielding are the best solutions to prevent crosstalk. Conclusions: Crosstalk and other forms of optical interference can corrupt pulse oximeter readings. Proper sensor placement and use of optical shielding of sensors are crucial steps to help protect the integrity of the data. Studies to further characterize crosstalk during pulse oximeter comparison studies are needed.

Published: August 2023

Thermochemical conversion of garden waste to biochar was carried out to prepare a green adsorbent for the removal of Cs, Cu, Ni, and Pb, which was characterized by XPS, SEM–EDX, and FT-IR analyses. The biocharˊs adsorption capacity was 20.5(Cs), 25.2(Cu), 12.4(Ni), and 45.9(Pb) mg g−1 and demonstrated satisfactory performance for different pH values. The kinetics data evaluation revealed that besides chemisorption, intraparticle diffusion contributes to metal removal. Moreover, the physical and structural properties of biochar play an important role in adsorption. Results indicate the suitability of using GW biochar as an alternative sorbent for both radionuclides and metal extraction.
Non-Gaussian Measures in Infinite Dimensional Spaces: the Gamma-Grey Noise
Authors: Beghin Luisa , Cristofaro Lorenzo , Gajda Janusz
Published: August 2023

In the context of non-Gaussian analysis, Schneider [29] introduced grey noise measures, built upon Mittag-Leffler functions; analogously, grey Brownian motion and its generalizations were constructed (see, for example, [6, 7, 9, 27]). In this paper, we construct and study a new non-Gaussian measure, by means of the incomplete-gamma function (exploiting its complete monotonicity). We label this measure Gamma-grey noise and we prove, for it, the existence of Appell system. The related generalized processes, in the infinite dimensional setting, are also defined and, through the use of the Riemann-Liouville fractional operators, the (possibly tempered) Gamma-grey Brownian motion is consequently introduced. A number of different characterizations of these processes are also provided, together with the integro-differential equation satisfied by their transition densities. They allow to model anomalous diffusions, mimicking the procedures of classical stochastic calculus.
Automatic Software Bug Prediction Using Adaptive Artificial Jelly Optimization With Long Short-Term Memory
Authors: Siva R. , S Kaliraj , Hariharan B. , Premkumar N.
Published: August 2023

In the software maintenance and development process, software bug detection is an essential problem because it is related to complete software success. It is recommended to begin anticipating defects at the early stages of creation rather than during the assessment process due to the high expense of fixing the found bugs. The early stage software bug detection is used to enhance software efficiency, reliability, and software quality. Nevertheless, creating a reliable bug-forecasting system is a difficult challenge. Therefore, in this paper, an efficient, software bug forecast is developed. The presented technique consists of three stages namely, pre-processing, feature selection, and bug prediction. At first, the input datasets are pre-processed to eliminate the identical data from the dataset. After the pre-processing, the important features are selected using an adaptive artificial jelly optimization algorithm (A2JO) to eliminate the possibility of overfitting and reduce the complexity. Finally, the selected features are given to the long short-term memory (LSTM) classifier to predict whether the given data is defective or non-defective. In this paper, investigations are shown on visibly obtainable bug prediction datasets namely, promise and NASA which is a repository for most open-source software. The efficiency of the presented approach is discussed based on various metrics namely, accuracy, F- measure, G-measure, and Matthews Correlation Coefficient (MCC). The experimental result shows our proposed method achieved the extreme accuracy of 93.41% for the Promise dataset and 92.8% for the NASA dataset.
The dreams they are a-changin’: Mixed-methods longitudinal research on young people’s patterns of orientation
Authors: Vogl Susanne , Valls Ona , Kogler Raphaela , Astleithner Franz
Published: August 2023

At the end of secondary general track schooling, young people experience an important transition; in Austria, they have to decide on further schooling or vocational training. Aspirations shape this transition and decisions herein. In this contribution, we explore patterns in formation, change or stability of educational and occupational aspirations. Based on an exploratory longitudinal mixed-methods approach with adolescents aged about 14 years in wave 1, we untangle the multidimensional phenomenon of (educational and occupational) aspirations. We analyze three waves of qualitative longitudinal interviews and develop a typology of young people’s educational and occupational orientation processes over time. In a statistical analysis of three waves of the panel survey data with the same age group, we compare and integrate findings on stability and change of aspirations and analyze the influence of sociodemographic characteristics on these patterns. With this mixed-methods longitudinal design, we gain an in-depth understanding of young peoples’ thoughts, ideas and worries during this transitional phase. We also learn about the resources that shape the orientation process and related patterns in time.

Authors: Wiedemann Gregor , Münch Felix Victor , Rau Jan Philipp , Kessling Phillip , Schmidt Jan-Hinrik
Published: August 2023

This article describes the basic concept, ethical and legal considerations, technical implementation as well as resulting tools and data collections of the Social Media Observatory (SMO). Since 2020, the SMO is developed as an open science research infrastructure within the Research Institute Social Cohesion (RISC) in Germany. It focuses on (the support of) long-term monitoring of public communication on selected platforms and online news media to answer social science-related research questions. Based on systematically compiled lists of public speaker categories, such as parliamentarians or media organizations, it collects statistics as well as content data to study the German social media discourse in comparison to mass media. Aggregated results are published via interactive dashboards. Raw data is published as ID lists for reproduction or shared with researchers upon request. Following a do-it-yourself approach to infrastructure, the SMO further provides various tools, curated datasets, and documented workflows, for instance, to run thematic ad-hoc data collections. As a main feature, it maintains a curated knowledge base in wiki format to enable other researchers to perform systematic social media observations on their own.
Learning about climate change with comics and text: a comparative study
Authors: von Reumont Frederik , Budke Alexandra
Published: August 2023

Climate change education has a high priority in the current global situation. Traditional learning material like text does not meet the needs of young learners, because of the complexity of the problem. We designed learning material in the comics form merging visual storytelling with scientific geographical communication devices such as maps, charts and diagrams. In an experimental research design, we found that this comic is more effective for learning about climate change than text with the same content, particularly regarding understanding and retaining the material’s content and development of environmental concerns. We strongly recommend using more comics for the support of cognitive performance of young learners for learning about climate change where human–environmental interaction is a focal point.
On the Temperature-Dependence of Deformation-Induced Martensite Formation in AISI 304L Type Steel
Authors: Egels G. , Bussmann M. , Benito S. , Weber S.
Published: August 2023

In this study, the deformation-induced α-martensite formation in AISI 304L steel was investigated in the temperature range between 75 °C and − 196 °C in the light of the temperature-dependence of hydrogen embrittlement phenomena. For this purpose, tensile tests with in-situ and ex-situ magnetic measurement of the α-martensite volume content as a function of plastic strain were carried out. In addition, a theoretical assessment of the temperature-dependence of the austenite stability was undertaken, evaluating chemical and non-chemical driving force contributions to the martensitic γ → α transformation as proposed by Ghosh and Olson. The experimental results clearly show an increase in the α-martensite volume content and a shifting of the phase transformation to lower strain levels upon reducing the temperature to − 75 °C. A further reduction of the temperature to − 196 °C revealed to have no significant impact on the α-martensite formation. The theoretical assessments indicate a similar temperature-dependence of the austenite stability as observed experimentally and suggest contributions of the thermal friction work at the fcc/bcc interface to be responsible for a constant austenite stability in low-temperature regimes. Additional investigations of deformed microstructures showed that element segregation effects on the local austenite stability are pronounced around room temperature, but become less relevant at low temperatures.

Published: August 2023

Detailed characteristics wear particles formed in various brake pads were done. Our study was focused on identification structure and chemical composition of powder particles released by brake abrasion. The experimental studies were carried out using Mössbauer spectroscopy, X-ray powder diffraction, scanning electron microscopy and magnetic measurements. Structure and chemical composition of the original brake pads and disc samples were compared with the results obtained for wear particles. The chemical and phase composition of wear particles is in large part similar to composition of the original brake pads. Wear particles contained mainly various types of iron oxides, iron and iron carbon metallic particles. The part of the wear particles showed paramagnetic behaviour at room temperature. The sample with fully paramagnetic wear particles behaviour was subjected low temperature Mössbauer and magnetic measurements. The results indicate transition interval corresponding to magnetically ordered states—ferro/antiferromagnetic.

The Role of IgA in the Manifestation and Prevention of Allergic Immune Responses
Authors: Scheurer Stephan , Junker Ann-Christine , He Chaoqi , Schülke Stefan , Toda Masako
Published: August 2023

Purpose of Review

Immunoglobulin A (IgA) mediates immune exclusion of antigens in the gut. Notably, IgA plays also a role in the prevention of IgE-mediated allergies and induction of immune tolerance. The present review addresses the role of IgA in the manifestation of IgE-mediated allergies, including allergen-specific immunotherapy (AIT), the regulation of IgA production, and the mechanism of IgA in immune cell activation.

Recent Findings

The majority of studies report an association of IgA with the induction of immune tolerance in IgE-mediated allergies. However, reports on the involvement of humoral and mucosal IgA, IgA subtypes, monomeric and polymeric IgA, and the mechanism of IgA-mediated immune cell activation are confounding.

Effects by IgA are likely mediated by alteration of microbiota, IgE-blocking capacity, or activation of inhibitory signaling pathways. However, the precise mechanism of IgA-regulation, the contribution of serum and/or mucosal IgA, and IgA1/2 subtypes, on the manifestation of IgE-mediated allergies, and the underlying immune modulatory mechanism are still elusive.

Published: August 2023

We aim to provide an overview of the research available on indoor radon and lung cancer, with a special focus on Spanish investigations. Early studies on underground miners established the link between radon and lung cancer, which was later confirmed for the general population by residential case–control studies. Spain contributed with extensive evidence, including 5 multicentric, hospital-based, case–control studies in the last 30 years, exploring diverse aspects, such as radon's effect on never-smokers, molecular pathways linking radon exposure to lung cancer risk, survival rates, mortality burden, and occupational exposure. There is a well-established causal association between radon with lung cancer. Despite pioneering research performed in our country by the Galician Radon Laboratory, particularly on driver genes, the evidence on the potential molecular pathways which makes radon a carcinogen is sparse. Also, relevant questions on the potential association of radon exposure with the induction of other diseases are still pending.

Context-Aware News Recommendation System: Incorporating Contextual Information and Collaborative Filtering Techniques
Authors: Alabduljabbar Reham , Almazrou Halah , Aldawod Amaal
Published: August 2023

With the increasing volume of news articles available on the internet, personalized news recommendations have become increasingly important for users to discover relevant and interesting news articles. However, traditional recommender systems often fail to capture the dynamic nature of users' preferences and the changing trends in news articles. To address this challenge, this paper proposes a context-aware personalized news recommendation system that incorporates contextual information to enhance the personalization of news recommendations. The approach involves collecting, extracting, exploring, cleaning, and processing a large dataset of news articles from 19 distinct internet news sources, totaling 22,657 English pieces. Four different recommender systems were built using different techniques, including content-based methods such as TF-IDF, Bag-of-Words, and Word2Vec, and a collaborative filtering system based on click behavior. To evaluate the effectiveness of our models, we used a combination of standard comparison metric, including precision and recall, and user feedback. To demonstrate the applicability of the model, a web interface was constructed, and we used RMSE and MAE to evaluate the performance of the collaborative filtering model. In addition, we conducted a comparative study to compare the accuracy of different algorithms with different baseline methods, including random and recency. The evaluation results showed that incorporating contextual information and collaborative filtering can significantly improve the personalization of news recommendations. The study suggests that the collaborative filtering model based on click behavior is the most effective approach, with a mean MAE of 0.0252 and a mean RMSE of 0.0364. The content-based models were also effective approaches for recommending news articles, outperforming the baseline approaches.

Abstract

Objectives

Pain is one of the most significant problems, and its uncontrolled management can lead to complications such as increased blood pressure, myocardial ischemia, etc. An effective approach to control postoperative pain is preemptive pain management with a combination of drugs prior to surgery. The present study aims to compare the level of postoperative abdominal pain in patients receiving pregabalin and famotidine versus pregabalin and diphenhydramine.

Materials and methods

In this double-blind clinical trial, a total of 34 candidates for abdominal surgery (laparotomy) with ASA physical status classification of 1 or 2 were enrolled from the patients referring to (XXX). They were divided into two groups of 17 (Group A: pregabalin and famotidine, Group B: pregabalin and diphenhydramine). The drugs were administered to the patients 2 h before the surgery. The patients’ pain levels were measured using the Visual Analog Scale (VAS) at the recovery stage after complete consciousness and at 6, 12, and 24 h postoperatively. Additionally, the amount of analgesic consumed within the first 24 h after the surgery was recorded and compared between the two groups.

Results

The average pain intensity score at 6 h postoperatively was (6 ± 0.2) in patients who received pregabalin and diphenhydramine, and (7.1 ± 0.1) in patients who received pregabalin and famotidine (p = 0.002). The average pain intensity score at 12 h postoperatively was (6.1 ± 0.3) in patients who received pregabalin and famotidine, and (5.6 ± 0.2) in patients who received pregabalin and diphenhydramine (p = 0.021). Furthermore, the average pain intensity score at 24 h postoperatively was (5.2 ± 0.2) in patients who received pregabalin and famotidine, and (4.2 ± 0.2) in patients who received pregabalin and diphenhydramine (p = 0.014). The results demonstrated that the pain intensity score decreased in all four measured time intervals in the overall patient population (p < 0.001), and this reduction was significantly different between the two groups (p = 0.002), with the final average pain score being lower in the group receiving pregabalin and diphenhydramine compared to the other group.

Conclusion

The results of this study indicate that the use of drugs such as diphenhydramine and pregabalin as preemptive medications can be effective in controlling postoperative abdominal pain and reducing the consumption of analgesics in patients after abdominal surgery.

Highlights
Root Seeking and Remote Sensing with the Bunun in the Mountains of Taiwan
Authors: Cheng Chieh-fu Jeff
Published: August 2023

Many Indigenous groups in Taiwan, including the Bunun, inhabited remote mountainous regions. Beginning in the 1930s, all mountain settlements were relocated to lower-lying areas by the colonial authorities. These groups lost the territories where they used to hunt, practice slash-and-burn agriculture, and carry out other social and cultural practices. Having being separated from their ancestral lands for decades, their knowledge of their former settlements and traditional ways of life is gradually disappearing. In recent years, there is a tendency among the younger generation of Indigenous people to organize and participate in roots-seeking expeditions. As their knowledge about the former settlements is limited, they seek help from the elderly—and archaeologists. Since 2014, I have collaborated with Bunun communities, recording their ancestors’ lands in the Lakulaku River Basin by joining archaeological surveys on roots-seeking trips. During these surveys, I had to learn Bunun values and gain knowledge of the Lakulaku River Basin via the bodily experience of moving through and being in the landscape with its traditional inhabitants. By applying remote-sensing technologies such as airborne lidar in our surveys, our team managed to identify and record settlements that were unfamiliar to the Bunun.
Gaussian fluctuations in the equipartition principle for Wigner matrices
Authors: Cipolloni Giorgio , Erdős László , Henheik Joscha , Kolupaiev Oleksii
Published: August 2023

The total energy of an eigenstate in a composite quantum system tends to be distributed equally among its constituents. We identify the quantum fluctuation around this equipartition principle in the simplest disordered quantum system consisting of linear combinations of Wigner matrices. As our main ingredient, we prove the Eigenstate Thermalisation Hypothesis and Gaussian fluctuation for general quadratic forms of the bulk eigenvectors of Wigner matrices with an arbitrary deformation.
THE ARCHITECTURE OF THE AUGUSTINIAN FRIARY, CAMBRIDGE
Authors: Cessford Craig , Samuel Mark , Herring Vicki , Holder Nick , Mills Philip
Published: August 2023

The Augustinian friary in Cambridge, England, was founded in the 1280s and dissolved in 1538. Investigations in 1908–9 and 2016–19 have revealed much of the friary cloister, with evidence for an initial late thirteenth–mid-fourteenth-century phase, a major phase of construction in the mid–late fourteenth century and some fifteenth-century construction. This paper will primarily consider what can be reconstructed of the claustral buildings, complemented by what is known of the rest of the friary site. The friary will also be contextualised in terms of mendicant beliefs and anti-fraternal criticisms.
ARISTOPHANES VS PHRYNICHUS IN FROGS
Authors: Lewis Amy S.
Published: August 2023

Aristophanes’ Frogs was first performed at the Lenaea festival of 405 in competition with Plato's Cleophon and Phrynichus’ Muses. This paper argues that Frogs contains a series of agonistic jokes against Phrynichus, most of which have gone unnoticed because he shares his name with a tragic poet and a politician; Aristophanes plays with the ambiguity of the name Phrynichus to mock his Lenaean rival by comparing him unfavourably with his namesakes. Aristophanes ultimately claims that his comedy is superior to that of Phrynichus because he is more successful than his rival in appropriating and redeploying other comedians’ material.
Gyrokinetic applications in electron–positron and non-neutral plasmas

Published: August 2023

In this paper, we summarize our recent work on gyrokinetic applications in electron–positron and non-neutral plasma. The electrostatic stability of electron–positron plasmas was investigated in dipole and slab geometries, with and without ion admixture. The gyrokinetic dispersion relation was derived and, for the slab case, extended to non-neutral plasmas. Here, we further extend the gyrokinetic formulation to the relativistic regime. Electron–positron plasmas are found to be remarkably stable as long as perfect symmetry between the two species prevails, but instabilities appear if this symmetry is broken, for instance by the introduction of impurities or magnetic curvature.

The following article seeks to question the deterministic tinge behind entanglement fetishism, namely the celebratory, uninhibited, and totalising projection of the world as a relational wholeness. Alongside the rise of Anthropocene debates and the claimed incapacity of post-positivism to account for contemporary socio-natural transformations, the text embarks on two main goals. On the one hand, the article sketches a brief genealogy of processual and relational thinking, with a focus on International Relations (IR) literature. On the other hand, the text seeks to move forward critical engagements with the entangled grand narrative. To this end, the article exposes a problematic ontological assumption often overlooked by both entanglement fetishists and their critics: entanglements are infallibly generative, that is to say, they deterministically precipitate further beings and events. In doing so, the text invites IR scholarship to explore non-generative encounters and hence to address the question of the possibility of being without being in relation. Drawing from an unorthodox line of research, the article unearths non-relational, or beyond-the-relational, instances, whose engagement with an entangled world can only be materialised through the logics of subjugation. For this mode of being, the texts hints, non-engagement, refusal, and withdrawal become a form of political resistance and survival, thus distorting the controversial association between political subjectivity and emancipation.
High risk of necrotising enterocolitis in term-born neonates with CHD delivered by caesarean section: a case–control study

Objective:

Necrotising enterocolitis is linked with altered intestinal microbiota, and caesarean birth is associated with imbalance of newborn intestinal microbiome. We aimed to investigate the role of delivery mode (vaginal or caesarean) and gestational age in the development of necrotising enterocolitis among term-born neonates (≥ 37 weeks) with CHD.

Methods:

Case–control study. We studied all newborns with CHD who underwent cardiac surgery during the neonatal (≤ 28 days of age) period, between 2007 and 2017. Totally, 60 cases of necrotising enterocolitis were matched (by year of birth and type of congenital heart lesion) with 180 controls (1:3 ratio). Multivariable conditional logistic regression was used to assess the study question.

Results:

The overall prevalence of necrotising enterocolitis was 6.3% in term-born newborns with CHD. Neonates with a left-ventricular outflow tract lesion or single ventricle lesion accounted for 55% (n = 33) of cases. 62% (n = 37) cases were in the modified Bell’s stage 2 or more for necrotising enterocolitis classification. In multivariable modelling, gestational age at birth was not associated with the development of necrotising enterocolitis [adjusted odds ratio per week increase, 95% confidence interval: 1.20 (0.90–1.60)]. Birth by caesarean delivery (compared to vaginal) was strongly associated with development of necrotising enterocolitis [adjusted odds ratio (95% confidence interval): 2.64 (1.31–5.29)]. We failed to identify an association between preoperative enteral nutrition and necrotising enterocolitis.

Conclusion:

This study showed a high risk of necrotising enterocolitis in newborns with critical CHD born via caesarean. This information is important given the high prevalence of planned birth by caesarean in newborns with CHD.

Objectives:

Poor oral feeding is a known contributor to growth challenges in neonates with complex CHD who require early surgery. Almost 60% of these infants do not achieve full oral feeding by hospital discharge. This study’s objective was to identify predictors of the inability to achieve full oral feeding by discharge in neonates with complex CHD following surgical intervention with cardiopulmonary bypass.

Study Design:

A retrospective analysis of a prospective study of 192 full-term neonates with complex CHD was performed. A stepwise selection logistic regression model was developed to predict oral feeding status at hospital discharge. Univariate subgroup analysis was performed with groups determined based on a CHD classification system.

Results:

58% of neonates (112/192) failed to achieve full oral feeding by hospital discharge. A logistic regression model identified duration of deep hypothermic circulatory arrest and reintubation as predictors of the inability to achieve full oral feeding. Among neonates who achieved full oral feeding by discharge (42%), only 7.5% did so after postoperative day 10. Brain maturation, brain injury, and preoperative oral feeding were not predictors of full postoperative oral feeding.

Conclusions:

Many infants with CHD fail to achieve full oral feeding by time of hospital discharge. Longer duration of deep hypothermic circulatory arrest and increased number of intubations were predictive of poor feeding after surgery. Prolonging hospitalisation solely to achieve full oral feeding after postoperative day ten is of limited utility; earlier discharge should be promoted to avoid negative impacts on neonatal neurodevelopment as unintended consequences of lengthy hospitalisations.
ODD RANK VECTOR BUNDLES IN ETA-PERIODIC MOTIVIC HOMOTOPY THEORY
Authors: Haution Olivier
Published: August 2023

We observe that, in the eta-periodic motivic stable homotopy category, odd rank vector bundles behave to some extent as if they had a nowhere vanishing section. We discuss some consequences concerning$\operatorname {\mathrm {SL}}^c$-orientations of motivic ring spectra and the étale classifying spaces of certain algebraic groups. In particular, we compute the classifying spaces of diagonalisable groups in the eta-periodic motivic stable homotopy category.
A Southern White Clergyman, the Freed People, and the Nineteenth-Century Episcopal Church
Authors: Mead Loren B. , Martinez J. Michael
Published: August 2023

Reared in antebellum South Carolina, Peter Fayssoux Stevens was a typical white southerner until Reconstruction. He came of age in the 1840s and 1850s and fought for the Southern Confederacy during the Civil War. Before his military service commenced in 1861, he was ordained a priest in the Protestant Episcopal Church (PEC) of North America. After Appomattox, as Black communicants deserted white Protestant churches in droves, Stevens believed that they might return to the PEC if they could choose their leaders and decide fundamental questions affecting their parishes. When white church leaders refused to follow Stevens’s recommendations, he left the PEC and joined the Reformed Episcopal Church (REC). He spent more than four decades after the war ministering to Black communicants. Although Stevens was not a champion of civil rights, his career provides a compelling case study of a white clergyman who evolved from a traditional southerner and zealous Confederate soldier to an advocate for Black communicants in the church.
As clear as Herculaneum mud: a plea for clarity
Authors: Moran Jerome
Published: August 2023

This article is by way of a request to experts who wish to make their expertise accessible to the non-expert. Non omnia possumus omnes, as Virgil said. In this case the deficiency is the lack of familiarity with papyrology and its conventions, in particular the papyri discovered in the library of the Villa of the Papyri at Herculaneum. The article shows how expertise can hinder rather than help the understanding of information needed for the processing of crucial data by the non-expert.
Discussion and Fairness in a Laboratory Voting Experiment
Authors: Woon Jonathan , Jang Minsu , Pronin Kira , Schiller Jacob
Published: August 2023

We conduct a laboratory experiment to investigate whether public discussion before a majority vote increases the saliency of minority interests and results in more egalitarian outcomes or whether voters use discussion to form majorities that benefit at the expense of minorities. When there are two alternatives, we find that public discussion increases the likelihood that individuals vote for equal allocations, but has little to no impact on the group outcomes. When participants choose among one equal and several unequal options, the multitude of unequal options creates a coordination problem, and we find that discussion decreases the frequency of egalitarian decisions. Our findings suggest that the effect of public communication on the fairness of majority voting outcomes depends on the strategic environment.

A flaperon belonging to Malaysian Airlines flight MH370 washed ashore on Réunion Island covered with the barnacle Lepas anatifera in July 2015, more than a year after the plane's disappearance. Here, we report the first high‐precision δ18Ocalcite versus temperature relationship for L. anatifera reared under laboratory conditions to unlock clues to the flaperon's drift path and origin. Using this experimental relationship and known growth rates for L. anatifera, we also demonstrate a new method for (a) converting δ18O data for one of the MH370 barnacles into a dated time series of sea surface temperatures (SSTs) experienced during the last part of the flaperon's drift and (b) identifying best fits between the observed flaperon SST time series and 50,000 SST histories generated from a particle‐tracking simulation. Our new method identifies a flaperon drift path far south of a previous isotope‐based reconstruction. We conclude with specific recommendations for using our method to continue the search for MH370 and other applications.

The Pacific decadal oscillation (PDO) is a decadal variability phenomenon occurring in the North Pacific Ocean. It has substantial impacts on marine ecosystems and the global climate. Due to the high complexity and unclear evolution mechanism, the accurate long‐term prediction of PDO remains a challenge. In this paper, a deep spatiotemporal embedding network (DSEN) is proposed to extract the spatiotemporal features from historical climate data and achieve end‐to‐end forecasting of the PDO index. The spatiotemporal features are recursive in the continuous forecasting of the PDO index on seasonal time scales, thus the cumulative error is largely reduced. During the test period of 39 years (1982–2020), our model can skillfully predict the PDO index up to 1 year, outperforming six methods used as benchmark. By contrast with physically‐based methods, DSEN can accurately predict the PDO index from a data‐driven perspective.
