Augmented Subspace Method for Semilinear Parabolic Problems Based on Symmetric Interior Penalty Discontinuous Galerkin Method
Authors: Chen Fan , Yan Erhankang , Zhou Chenguang
Published: September 2024

In this paper, we propose an augmented subspace method for solving semilinear parabolic equations based on the Symmetric Interior Penalty Discontinuous Galerkin (SIPDG) method. The main idea of this method is, at each time step, to convert the solution of the semilinear elliptic problem into the solution of the corresponding linear boundary value problem on the same-scale discontinuous finite element space and the solution of the semilinear elliptic problem on a newly defined low-dimensional augmented subspace. The prior error estimates are derived. Numerical experiments are conducted to confirm the theoretical conclusions and the computing efficiency of the proposed method.
Effect of A/B sites co-doping on the structure, electric and dielectric properties of CaTiSiO5 ceramics
Authors: Ni Hanwen , He Zichen , Liu Zhifu
Published: September 2024

Dielectrics with high permittivity and temperature stability are important for the development of high-temperature multilayer ceramic capacitors (MLCCs). In this study, Ca[Formula: see text]NaxTi[Formula: see text]NbxSiO5 (abbreviated as CTS[Formula: see text]NN) ceramics were prepared by solid-phase reaction method. The introduction of NN weakens the long-range ordered displacement of Ti, leading to a significant increase in the dielectric temperature stability. The CTS−2%NN samples exhibit high permittivity (53) and TCC [Formula: see text] ppm/∘C in the range of [Formula: see text]C to 300∘C. The CTS-based ceramics behave high dielectric temperature stability. In addition, the bandgap of the CTS-based ceramics increased significantly, which is favorable for improving the breakdown strength of the material. For [Formula: see text]% samples, the breakdown strength reaches 621[Formula: see text]kV/cm. Thus, the designed CTS-based dielectrics are promising for high-temperature capacitors.

The
Hypsilophodon
Bed occurs at the top of the Wessex Formation (Early Cretaceous, Barremian) on the Isle of Wight, southern England. Numerous remains of the small ornithopod dinosaur
Hypsilophodon foxii
have been recovered from the bed since the mid-nineteenth century. Previous theories for these fossil occurrences have focused on catastrophic mass death events, including miring and flood-related mortality. However, only limited sedimentological and taphonomic analyses of the horizon and its fossil assemblage have been undertaken, hindering efforts to evaluate different theories about how the assemblage formed. Here, we report a sedimentological study of the bed to constrain its depositional environment, an examination of the matrix from
Hypsilophodon
fossils to identify where they were collected from within the bed, and a taphonomic investigation of
Hypsilophodon
specimens. Our results indicate a floodplain environment, which later became a marsh and then mudflats at the edge of a lagoon.
Hypsilophodon
fossils are spatially and stratigraphically distributed throughout the bed. The specimens are largely incomplete and unabraded, suggesting that most perished on, or near to, the floodplain and may have lain exposed for some time prior to burial. Overall, the evidence suggests that the fossil assemblage of the
Hypsilophodon
Bed formed as an accumulation of remains over time.
Confidential Computing Proofs
Authors: Russinovich Mark , Fournet Cédric , Zaverucha Greg , Benaloh Josh , Murdoch Brandon , Costa Manuel
Published: September 2024

Proofs are powerful tools for integrity and privacy, enabling the verifier to delegate a computation and still verify its correct execution, and enabling the prover to keep the details of the computation private. Both CCP and ZKP can achieve soundness and zero-knowledge but with important differences. CCP relies on hardware trust assumptions, which yield high performance and additional confidentiality protection for the prover but may be unacceptable for some applications. CCP is also often easier to use, notably with existing code, whereas ZKP comes with a large prover overhead that may be unpractical for some applications.
The Evolution of Queen Pheromone Production and Detection in the Reproductive Division of Labor in Social Insects
Authors: Liebig Juergen , Amsalem Etya
Published: September 2024

Structurally diverse queen pheromones and fertility signals regulate the reproductive division of labor of social insects, such as ants, termites, some bees, and some wasps. The independent evolution of sociality in these taxa allows for the exploration of how natural history differences in sender and receiver properties led to the evolution of these complex communication systems. While describing the different effects and the structural diversity of queen pheromones, we identify two major syndromes that mostly separate ants and wasps from bees and termites in their use of different pheromone classes. We compare olfactory receptor evolution among these groups and review physiological and hormonal links to fecundity and pheromone production. We explore the cases in which queen pheromone evolution is conserved, convergent, or parallel and those in which queen pheromone responses are more likely to be learned or innate. More mechanistic information about the pathways linking fecundity to queen pheromone production and perception could help close major knowledge gaps.
Fluid Mechanics of the Dead Sea
Authors: Meiburg Eckart , Lensky Nadav G.
Published: September 2024

The environmental setting of the Dead Sea combines several aspects whose interplay creates flow phenomena and transport processes that cannot be observed anywhere else on Earth. As a terminal lake with a rapidly declining surface level, the Dead Sea has a salinity that is close to saturation, so that the buoyancy-driven flows common in lakes are coupled to precipitation and dissolution, and large amounts of salt are being deposited year-round. The Dead Sea is the only hypersaline lake deep enough to form a thermohaline stratification during the summer, which gives rise to descending supersaturated dissolved-salt fingers that precipitate halite particles. In contrast, during the winter the entire supersaturated, well-mixed water column produces halite. The rapid lake level decline of O(1 m/year) exposes vast areas of newly formed beach every year, which exhibit deep incisions from streams. Taken together, these phenomena provide insight into the enigmatic salt giants observed in the Earth's geological record and offer lessons regarding the stability, erosion, and protection of arid coastlines under sea level change.
Metabolic Flux Modeling in Marine Ecosystems
Authors: Scott Helen , Segrè Daniel
Published: September 2024

Ocean metabolism constitutes a complex, multiscale ensemble of biochemical reaction networks harbored within and between the boundaries of a myriad of organisms. Gaining a quantitative understanding of how these networks operate requires mathematical tools capable of solving in silico the resource allocation problem each cell faces in real life. Toward this goal, stoichiometric modeling of metabolism, such as flux balance analysis, has emerged as a powerful computational tool for unraveling the intricacies of metabolic processes in microbes, microbial communities, and multicellular organisms. Here, we provide an overview of this approach and its applications, future prospects, and practical considerations in the context of marine sciences. We explore how flux balance analysis has been employed to study marine organisms, help elucidate nutrient cycling, and predict metabolic capabilities within diverse marine environments, and highlight future prospects for this field in advancing our knowledge of marine ecosystems and their sustainability.
Optimization of Post-Annealing Temperature of RF Magnetron-Sputtered ZnO Thin Films for Enhancing Performances of UV Photodetectors
Authors: Wei Xueyuan , Liu Yao , Wei Lesi
Published: September 2024

In this study, we examined the surface morphology and crystal structure of RF-sputtered ZnO thin films that were annealed at various temperatures. Also, we fabricated UV photodetectors with an Au-ZnO-ITO sandwich structure, utilizing the thin films annealed at 600 °C. The surface roughness of the film initially increases and then decreases as the annealing temperature rises, and the crystalline quality improves with an increase in the annealing temperature. Due to the Schottky heterojunction formed by the Au-semi contact, the fabricated UV photodetector exhibits a responsivity of 7.91 mA W−1 under 405 nm UV light. And the device demonstrates high response stability and rapid response sensitivity, with a swift rise time of 80 ms at a light intensity of 2.56 mW cm−2.

Published: September 2024

Although chloramphenicol(CAP) plays a critical role in many medical treatments, its abuse is not only seriously toxic to humans but also ecologically harmful when discharged into the water. Therefore, it is of great significance to realize the rapid and efficient detection of CAP. 2D MOFs Cu3(HITP)2 (HITP = 2,3,6,7,10,11-hexaiminotriphenylene) with higher electrical conductivity than conventional MOFs were synthesized using hydrothermal methods. Fc-NH2, as an electron donor, was dispersed on the surface of MOFs by physical doping. The synthesized nanocomposite Cu3(HITP)2/Fc-NH2 has excellent adsorption properties and electrical conductivity. It was used to construct an electrochemical sensor and exhibited superior performance in the detection of CAP. Electrochemical reduction of CAP on Cu3(HITP)2/Fc-NH2/GCE was investigated using cyclic voltammetry and differential pulse voltammetry. The results show that Cu3(HITP)2/Fc-NH2/GCE has a much wider linear range of 0.5 ∼ 2100 μm than previous studies when detecting CAP. The detection limit is as low as 0.43 μm. The electrochemical sensing platform reported in this work also exhibits excellent reproducibility, selectivity, and stability, and the recovery rate of CAP detection in the actual sample ranged from 97.1% to 102.4%. This work provides a new strategy for antibiotic detection and extends the application of triphenylene-based MOFs in the electrochemical sensing field.

Published: September 2024

Ochratoxine A is a very stable mycotoxin which cannot be destroyed below 250°C. Found in grains, coffee, grapes, wine, milk, and meat, it can produce kidney damage and cancer. Therefore, a smartphone operated intellingent stochastic miniplatform was designed, characterised, and validated for the on-site screening of milk for fast determination of ochratoxine A. (Z)-N-[2-(4-hydroxyphenyl) ethyl]octadec-9-enamide was used as modifier of a gold matrix for a screen printed stochastic sensor used as sensing tool in the design of the miniplatform. A wide linear concentration range (1.0 × 10−15− 1.0 × 10−7mol l‒1) and a low limit of quantification of 1 fmol l‒1were achieved for the assay of ochratoxin A. Recovery values higher than 99.00% were obtained for ochratoxine A, when the miniplatform was used for the screening of cow’s milk and vegetarian milk.
Electrochemical Sensor based on N-Doped Graphite/Aluminum Silicate Nanocomposite Modified Carbon Paste for Simultaneous Detection of Paracetamol and Pamabrom
Authors: Sawan Haya S. , Merey Hanan A. , Mahmoud Amr M. , Atty Shimaa A.
Published: September 2024

We have developed an eco-friendly sensor through innovative modification of a carbon paste electrode with nanomaterials. This modification is based on employing a mixture of aluminum silicate and nitrogen-doped graphite nanocomposite (Al2SiO5/NG/CPE), introducing the first electrochemical approach for the voltammetric determination of a combination of paracetamol (PCM) and pamabrom (PAM), which is recognized as an over-the-counter remedy for menstrual cramp relief. N-doped graphite was prepared from graphite and urea using a metal-free soft nitriding method. The morphological characterization of the Al2SiO5/NG nanocomposite was investigated using transmission electron microscopy, energy dispersive X-ray spectroscopy, and X-ray photoelectron spectroscopy. The experimental conditions were optimized using square wave voltammetry and cyclic voltammetry techniques to explore the impact of scan rate, pH, and concentration. The results exhibited good linearity across a wide concentration range of 0.2 nM–100.0 μM for both drugs. The limits of detection for PCM and PAM were 25 and 24 pM, respectively, while the limits of quantification were 88.3 and 80.0 pM, showing the proposed sensor’s exceptional sensitivity. Furthermore, the proposed sensor was employed to determine the PCM/PAM mixture in bulk powder, pharmaceutical dosage forms, biological fluids, and in the presence of toxic paracetamol metabolites.

Published: September 2024

Phenolic compounds, prevalent in both human life and the natural environment, pose a significant threat to human health due to their toxic effects. Therefore, accurate determination of these compounds are crucial. Herein, we developed a new electrochemical sensor based on a NiO/C@reduced graphene oxide nanocomposite (NiO/C@rGO) to simultaneously assess three phenolic compounds: hydroquinone (HYQ), catechol (CAT), and bisphenol A (BPA). The NiO/C@rGO nanocomposite was synthesized via Ni(gallate)@GO pyrolysis and extensively characterized using various techniques. Subsequently, a glassy carbon electrode (GCE) modified with the NiO/C@rGO nanocomposite was utilized as the electrochemical sensor to simultaneously detection. The developed nanosensor (NiO/C@rGO/GCE) exhibited exceptional selectivity and a broad linear ranges for HYQ, CAT, and BPA, spanning from 0.01 to 100 μM, with impressively low detection limits. Furthermore, the NiO/C@rGO nanocomposite demonstrated remarkable stability and high reproducibility. Moreover, we successfully applied the NiO/C@rGO-based sensor to evaluate the three phenolic compounds in tap water, drinking water, and mineral water samples. The results underscore the potential of the developed electrochemical sensor as a reliable tool for the sensitive and fast detection of phenolic compounds in various water sources, addressing the critical need for safeguarding human health and the environment from their adverse effects.

Published: September 2024

Morning insulin exposure primes the liver for increased hepatic glucose uptake and glycogen storage during a subsequent hyperinsulinemic-hyperglycemic clamp. This study addressed whether the pattern and/or duration of insulin delivery in the morning influences insulin’s ensuing priming effect. We found that despite receiving equal total doses of insulin in the morning, a prolonged, lower rate of morning insulin delivery improved afternoon liver glucose metabolism more effectively than a shorter, higher rate of delivery.
Electrophysiological correlates of divergent projections in the avian superior olivary nucleus
Authors: Baldassano James F. , MacLeod Katrina M.
Published: September 2024

Inhibitory inputs for the avian brain stem originate primarily from the superior olivary nucleus (SON). We describe three intrinsic phenotypes of SON neurons and show how they differ in their temporal processing and projection patterns. We propose that the two types of tonic firing neurons (including one novel type) and the single-spiking neurons in SON comprise separate feedback circuits that may differentially influence the auditory information flowing via the cochlear nuclei and nucleus laminaris.
Saccades to both vision and touch are modified following adaptation but cross-modal transfers are asymmetrical
Authors: Batikh Ali , Gaveau Valérie , Panouillères Muriel T. N. , Koun Éric , Salemme Roméo , Farnè Alessandro , Pélisson Denis
Published: September 2024

The present study revealed that, as predicted from a large literature, adaptation of visual reactive saccades transfers to tactile saccades of the same as well as neighboring amplitudes. Furthermore, in a modified double-step target paradigm, tactile saccades exposed to repeated errors adapt with a similar rate and spatial generalization as visual saccades, but this adaptation only slightly transfers to visual saccades. These findings bring new information on saccadic adaptation processes.

Manhwas norte-coreanos como ferramenta estatal de propagação da filosofia Juche
Authors: Alberto Felipe Vidal Benvenuto
Published: September 2024

It aims to correlate comics in North Korea with the sociopolitical context in which the country is historically embedded. In order to do so, we start from the premise of a presumed causal relationship between the numerous war propaganda materials in comics from Japan and the perpetuation of such media for the same purpose in the northern portion of the Korean Peninsula, given that part of the local government's policy consists of narrating the imminence of a conflict with its major global enemies. Methodologically, we employ documentary sources, essentially consisting of North Korean comics produced in the last three decades, which allow relevant interpretations of the selected theme, contextualizing the formation of that country as influenced by the deleterious Japanese military occupation. By incorporating the complexities of the current international system into the context of maintaining the local regime, it becomes possible to better understand and characterize North Korean manhwas as cultural inputs that possess a rich power of social cohesion targeting all age groups, like what occurs in more open and vibrant markets.

A história de resistência à escravidão no Brasil por meio da linguagem expressiva dos quadrinhos em Cumbe, de Marcelo D’ Salete (2018)
Authors: Rocha Inez Neres de Almeida
Published: September 2024

O objeto do estudo é a história em quadrinho Cumbe, de Marcelo D’ Salete (2018), que traz histórias no período colonial no Brasil. Nesta produção estão compiladas quatro narrativas independentes que tratam da resistência dos negros à escravização no Brasil entre 1500 e 1888, ano da abolição. Foi selecionada a primeira história, “Calunga”, visando demonstrar quais recursos dos quadrinhos foram utilizados para dar ênfase às expressões faciais dos personagens em situação de escravidão. O objetivo é verificar como a linguagem quadrinística está em funcionamento nessa história. A partir da análise interpretativista, verifica-se a dinamicidade, expressividade, ângulo e planos de visão e uma contextualização histórica em relação ao tempo histórico com base de nos pressupostos teóricos de Acevedo (1990), Ramos (2010) e Cagnin (2014) para a caracterização da linguagem dos quadrinhos, bem como de Mattoso (1990) para compreender a história da escravidão no Brasil. Foi constatado que os recursos da linguagem dos quadrinhos são elementos importantes que caracterizam e traduzem as emoções e sentimentos dos personagens, mas sem personagens, não há histórias.

Authors: Reino Lucas , Bueno Thaísa
Published: September 2024

Pointed as one of the most visible examples of participatory audience posture on the internet, readers’ comments do not always interfere with the routine of the vehicles and are often ignored by media producers. But, sometimes, some posts leave the limbo and gain prominence in the routine of the vehicles. Thus, the proposal of this article is to present a catalog of some models of use of this content by the media and understand how and why in some cases the posts are used by the press. The cut of the research includes the monitoring of 22 vehicles that offer the possibility to comment between printed newspapers, magazines and news portals in Brazil, having as a selection criterion the circulation. The result points to a frequency and typology of use below its potentiality.

A relação entre festa e engajamento na manifestação #EleNão
Authors: Wrublevski Matilde
Published: September 2024

The 2018 #EleNão Protest in Brazil showed a significant participation of the population. Analysis, by experience and reflection, of this protest in the municipality of São Paulo, found a composition permeated by festive elements. Thus, the notion of party dramaturgy as a proposition of aspects that indicate the relevant relation between art, politics, and festivities can highlight the encounter as points of discussion to analyze the #EleNão case. Between celebration and protest, the festivity merges as a fragmented expression that enables a dialectical participation and the exposition of pluralized positions, which exceed its main agenda.
Benedicto Nicolau dos Santos: um intelectual e compositor negro e sua participação no Paranismo
Authors: Coelho Daniele Martinez de Oliveira , Lemos Junior Wilson , Vaz Adriana
Published: September 2024

The objective of the article is to present aspects of the life trajectory and work of Benedicto Nicolau dos Santos, a black intellectual, musician and his participation in the construction of Paranist ideology. For Benedicto, the language of music and theater aimed at cultural formation and social refinement. Among the concepts used, the following stand out: that of trajectory, habitus and capital by Bourdieu (2001, 2009), that of sociability network by Sirinelli (2003), and that of intellectual by Vieira (2011), as well as the contributions of Otto (2015) that address Benedicto's musical production. The musical compositions presented belong to the collection of the Escola Paranaense de Música e Belas Artes (EMBAP). Son of a Portuguese man and an enslaved black woman, throughout his artistic and musical career, his racial origin was hidden most of the time. Its social and symbolic rise is based on racial cordiality and tacit racism (SALES JR., 2006). His social and symbolic rise was based on racial cordiality and the unspoken racist (SALES JR., 2006). His work in the artistic-musical field, combined with his network of sociability and vast musical production, including writings on theory, makes him an intellectual musician, as he propagates the Paranista ideal through his compositions such as “Hymno de Curityba” from 1928.
“Dá ku torno!”: Batuko e territórios identitários na diáspora caboverdiana
Authors: Coelho André
Published: September 2024

Este artigo propõe uma análise de processos de identificação existentes no batuku, prática expressiva originária da ilha de Santiago em Cabo Verde, através da observação da atuação das Batukadeiras X. Este grupo, formado na maioria por jovens nascidas em Portugal e Cabo Verde, ganhou destaque internacional ao participar na turnê Madame X da cantora norte-americana Madonna. O espetáculo integrava referências da cultura expressiva afro-portuguesa que a artista absorveu durante a sua estadia em Lisboa, entre 2017 e 2019, e através dessa colaboração, as integrantes das Batukadeiras X vivenciaram um regresso a uma pátria imaginada, ao se reconectar com suas raízes caboverdianas num contexto subalternizado. Este retorno às origens destas jovens não foi apenas um resgate cultural, mas também uma forma criativa de redescoberta e afirmação identitária. Esta vivência também permitiu que estas jovens refletissem sobre a agencialidade do corpo em espaços performáticos, e na conscientização do batuku enquanto prática expressiva da identidade e da memória coletiva, particularmente no contexto da diáspora.
Arte e pensamento negro como epistemologias críticas: contribuições para o ensino de música
Authors: Souza Stefani Silva
Published: September 2024

Based on the problematization of the lack of recognition of black intellectual productions and artists as an episteme, and in particular,  of Afro-referenced content in Brazilian musical literature, this article seeks to lead the reader to reflect on the processes of musical teaching and learning, from a decolonial and Afro-diasporic perspective. Seeking to weave a dialogue with the concept of black-body-territory, by the black historian and intellectual, Beatriz Nascimento, the text seeks to relate how the black body is inscribed in different environments based on the awareness and resumption of its ancestry, culture and origin. In the lines that are woven here, I seek to provoke the reader to the need to decentralize the hegemonic discourse of white-European tradition, which are undertaken in debates and recorded in books of musical theory and analysis, as well as in books of music history. Thus, the aim is to understand how the mechanisms of racial, class and gender oppression operate in the perpetuation of the symbolic erasure of the history and influence of the African continent on our musicality.
Predicting Late Gadolinium Enhancement of Acute Myocardial Infarction in Contrast-Free Cardiac Cine MRI Using Deep Generative Learning
Authors: Qi Haikun , Qian Pengfang , Tang Langlang , Chen Binghua , An Dongaolei , Wu Lian-Ming
Published: September 2024

BACKGROUND:

Late gadolinium enhancement (LGE) cardiac magnetic resonance (CMR) is a standard technique for diagnosing myocardial infarction (MI), which, however, poses risks due to gadolinium contrast usage. Techniques enabling MI assessment based on contrast-free CMR are desirable to overcome the limitations associated with contrast enhancement.

METHODS:

We introduce a novel deep generative learning method, termed cine-generated enhancement (CGE), which transforms standard contrast-free cine CMR into LGE-equivalent images for MI assessment. CGE features with multislice spatiotemporal feature extractor, enhancement contrast modulation, and sophisticated loss function. Data from 430 patients with acute MI from 3 centers were collected. After image quality control, 1525 pairs (289 patients) of center I were used for training, and 293 slices (52 patients) of the same center were reserved for internal testing. The 40 patients (401 slices) of the other 2 centers were used for external testing. The CGE robustness was further tested in 20 normal subjects in a public cine CMR data set. CGE images were compared with LGE for image quality assessment and MI quantification regarding scar size and transmurality.

RESULTS:

The CGE method produced images of superior quality to LGE in both internal and external data sets. There was a significant (
P
<0.001) correlation between CGE and LGE measurements of scar size (Pearson correlation, 0.79/0.80; intraclass correlation coefficient, 0.79/0.77) and transmurality (Pearson correlation, 0.76/0.64; intraclass correlation coefficient, 0.76/0.63) in internal/external data set. Considering all data sets, CGE demonstrated high sensitivity (91.27%) and specificity (95.83%) in detecting scars. Realistic enhancement images were obtained for the normal subjects in the public data set without false positive subjects.

CONCLUSIONS:

CGE achieved superior image quality to LGE and accurate scar delineation in patients with acute MI of both internal and external data sets. CGE can significantly simplify the CMR examination, reducing scan times and risks associated with gadolinium-based contrasts, which are crucial for acute patients.
Extensive Dysregulation of Phenylalanine Metabolism Is Associated With Stress Hyperphenylalaninemia and 30‐Day Death in Critically Ill Patients With Acute Decompensated Heart Failure
Authors: Chen Wei‐Siang , Liu Min‐Hui , Tsou Yi‐Liang , Wu Huang‐Ping , Lin Hsuan‐Ching , Liang Chung‐Yu , Wang Chao‐Hung
Published: September 2024

Background

Stress hyperphenylalaninemia predicts elevated mortality rates in patients with acute decompensated heart failure (ADHF). This study investigated the metabolic pathways underlying this association and identified a unique metabolic phenotype underlying the association between stress hyperphenylalaninemia and adverse outcomes in ADHF.

Methods and Results

This was a retrospective cohort study. We enrolled 120 patients with ADHF in an intensive care unit (60 with a phenylalanine level ≥112 μM, 60 with a phenylalanine level <112 μM), and 30 controls. Plasma phenylalanine‐derived metabolites were measured, and participants were evaluated for 30‐day death. Patients with ADHF had extensive activations of the alternative pathways for metabolizing phenylalanine, leading to the levels of phenylalanine‐derived downstream metabolites 1.5 to 6.1 times higher in patients with ADHF than in the controls (all
P
<0.001). Extensive dysregulation of these alternative pathways significantly increased phenylalanine levels and contributed to a distinct metabolic phenotype, characterized by increased phenylalanine, tyrosine, homogentisic acid, and succinylacetone levels but decreased benzoic acid and 3,4‐dihydroxyphenylalanine levels. Throughout the 30‐day follow‐up period, 47 (39.2%) patients died. This distinct metabolic phenotype was associated with an increased mortality rate (odds ratio, 1.59 [95% CI, 1.27–1.99];
P
<0.001). A multivariable analysis confirmed the independent association of this metabolic phenotype, in addition to phenylalanine and tyrosine levels, with 30‐day death.

Conclusions

In patients with ADHF, extensive dysregulation of the alternative pathways for metabolizing phenylalanine was correlated with stress hyperphenylalaninemia and a distinct metabolic phenotype on the phenylalanine–tyrosine–homogentisic acid–succinylacetone axis. Both stress hyperphenylalaninemia and metabolic dysregulation on this axis were associated with poor outcomes.
Commission, Mission and Migration in Acts
Authors: Keener Craig , Keener Médine
Published: September 2024

This response to the article by our friend and colleague Ekaputra Tupamahu expresses features of both appreciation and dissent. We should note at the outset, however, that a key part of the difference is likely semantic: how “mission” is defined. It may be more a specific model of mission to which Dr. Tupamahu objects, rather than every model of mission. In fact, as dialogue provides clarification, I suspect we have significant common ground. The colonial model of mission followed the model of Paul’s rivals in Galatia; Paul proclaimed the kingdom good news in a way that did not impose extrabiblical Jewish culture on gentiles. Indeed, Acts includes a clearly Asian mission to bring the good news to Europe.
Reading the Pentecostal Interpretations of the Book of Acts Contrapuntally
Authors: Wiyono Gani
Published: September 2024

This article responds to Ekaputra Tupamahu’s article that offers an alternative pentecostal reading of the book of Acts. Tupamahu challenges mainstream pentecostal interpretations that regard missionaries as pivotal characters in the Acts narrative. Alternatively, he suggests an interpretation focusing on migrants as the primary characters in the Acts narrative. In this article, these two opposing views are framed using an approach known as contrapuntal reading. The goal is not harmonization to reduce the tension between the two but to expand the horizon of the readers of Acts through the uniqueness of each reading.
The Pig Slaughter Ritual among Tayal Christians in Contemporary Taiwan: towards a Preliminary Theological Reflection
Authors: Lardinois Olivier
Published: September 2024

The pig slaughter ritual is still practiced by the Tayal aborigines in the mountainous area of northern Taiwan today. Even after the conversion of the majority of the Tayal people to Catholic and Protestant Christianity in the 1950s and 1960s, Tayal Christians continue to employ this ritual to cope with the challenges of an increasingly materialistic society. This article draws on years of fieldwork and pastoral ministry, including interviews with over sixty people, to investigate the compatibility of Tayal tribal ethics with Christian beliefs and values. It argues that the survival of the pig sacrifice ritual throws light on some significant transformations that Christianity has brought to the Tayal communities, especially with regards to a universal understanding of the world, the moral vision of living in solidarity with fellow Christians and helping strangers, and the protection of the environment.
Political Persuasion is Prima Facie Disrespectful
Authors: Marshall Colin
Published: September 2024

Political persuasion can express moral respect. In this article, however, I rely on two psychological assumptions to argue that political persuasion is prima facie disrespectful: (1) that we maintain our political beliefs largely for non-epistemic, personal reasons and (2) that our political beliefs are connected to our epistemic esteem. Given those assumptions, a persuader can either ignore the relevant personal reasons, explicitly address them, or implicitly address them. Ignoring those reasons, I argue, constitutes prima facie insensitivity. Explicitly addressing them constitutes a form of prima facie incivility. Finally, implicitly addressing them covertly treats those personal reasons as psychological puppet strings, constituting prima facie objectionable manipulation. This prima facie insensitivity, incivility, and manipulation are each prima facie failures of respect, either for the persuadee’s rationality or for their agency. Political persuasion can sometimes be all-things-considered justified, but these moral hazards can produce reasonable guilt, resentment, and blowback.
Multimodal marks of iteration in discourse
Authors: Lelandais Manon
Published: September 2024

This article investigates the way speakers combine different verbal and gestural resources to express aspectual meaning in American English, specifically the way an event is repeated. It identifies stable gestural correlates to the OVER AND OVER adverbial phrase, which involves lexical iteration. Speakers have been shown to rely on co-verbal gestures to communicate aspectual information along with lexical and grammatical means. However, most of the research has focused on hand gestures, and on comparing the embodiment of different categories of aspect. Cyclic gestures have particularly been found in aspectual contexts, and linked with meanings of motion, either physical or metaphorical, as well as continuity. We use video datasets of spoken American English belonging to the Distributed Little Red Hen Lab (Steen et al. 2018) as part of the UCLA Library NewsScape Archive. We determine which formal features participate in the expression of iteration, in a variety of articulators (hands, head, eyebrows), and carry out a quantitative analysis, targeting gesture proportion, timing, and duration. This study shows how gestural components blend in and participate in the expression of grammatical and pragmatic meaning in speech. More specifically, it adds to the ongoing discussion within Construction Grammar about conventionality in multimodal constructions.
Building and coordinating multimodal interaction with gaze across two communicative situations
Authors: Loulou Kosmala
Published: September 2024

During face-to-face interactions, gaze plays a fundamental role in shaping the status of co-participants. A shift in gaze direction can signal a form of engagement or joint attention if it is oriented towards the interlocutor, or by contrast a form of disengagement if it is averted. Gaze also contributes to the shaping and complex development of multimodal interaction, as it enables speakers to simultaneously maintain several viewpoints who constantly align to each other’s positionings within the activity in progress.

The present study focuses on the role of gaze direction and its coordination with other visible body behavior (i.e. hand gesture) found in interaction, more specifically in university settings. The analyses are carried out on the DisReg Corpus (Kosmala 2020) which comprises video recordings of French undergraduate students in two distinct situations: during individual oral presentations in class presented in front of the instructor and the students from the class, and during semi-spontaneous informal conversations between two students. The aim of this study is to illustrate the importance of gaze for building multimodal discourse across different communicative situations, combining quantitative and qualitative analyses through detailed annotations of gaze and its coordination with gestural actions. Results show that during class presentations, students look extensively towards their notes but pay very little attention to their audience, while during conversations, speakers mobilize several visual resources they have at their disposal, including gaze, to check visual attention, signal shifts in participation and viewpoint, and redirect attention to each other’s gestures.
Geste et participation des enfants aux interactions polyadiques
Authors: Caët Stéphanie
Published: September 2024

Gesture plays an important role in human communication and in the organisation of language interactions. Some theoretical models in psychology and linguistics also give it a central place. Gesture and the multimodality of children’s language productions have long been under particular attention. They have often been studied in the context of dyadic parent-child interactions. However, most children encounter numerous situations of multiparty interactions from birth, and children’s participation in these interactions contributes to the process of language acquisition.

The aim of this article is to highlight the relationship between gesture and children’s participation in multiparty interactions. On the basis of qualitative and quantitative analyses of corpora collected in spontaneous multiparty interactions in the framework of different research projects, we highlight the way in which gesture enables children to participate in interactions as speakers, addressees and observers, and we question the way in which the occupation of these different statuses can, in turn, contribute to the development of a gestural language competence.

The selection and organisation of the data presented were driven by the perspective of applied projects in early childhood education and care settings (where gesture is not systematically taken into account when measuring children’s participation) or with hearing families with a deaf child (where the potential of multiparty interactions for language development tends to be underestimated).
Impact de la formation sur la visibilité des gestes lors de l’interaction exolingue par visioconférence: une exploration méthodologique
Authors: Holt Benjamin
Published: September 2024

This article focuses on gesture production during video-mediated L1/L2 interaction. We use a corpus made up of two types of video-mediated interactions in order to study gesture visibility from two points of view. The first group is made up of future French teachers in training who practice teaching their L1 to learners of French. The second group is made up of L1 English and L1 French learners who interact in order practice speaking their respective L2s. By comparing the webcam recording to that of an external camera, we analyze the gesture visibility of interlocutors between these two groups in order to test a method that has the potential to determine whether or not teacher training could have an effect on gesture production.
Robert Merton and Jürgen Habermas: The cudos Norms and Free Argumentative Dialogue
Authors: Andersen Heine
Published: September 2024

In the book Science Studies as Naturalized Philosophy, Finn Collin deals with a long-term tendency toward conflict between, on the one hand, a philosophical understanding of scientific cognition and, on the other hand, the empirical science studies that include the cognitive content of sciences as an explanandum. Collin singles out Robert Merton as an advocate of a division of labor that avoids this conflict by delimiting the sociology of science to deal only with the social framework and genesis of science, leaving it to philosophy and epistemology to investigate the justification of truth value and demarcation criteria. In this article, I will focus on Merton’s cudos norms and illuminate their meta-theoretical basis through the inclusion of Habermas’s ideas about rationality, the ‘ideal speech situation,’ his formal pragmatics, and his use of rational reconstruction. I discuss whether this can be considered ‘naturalized philosophy.’
A Brief Sketch of Five Decades in Philosophy of Science
Authors: Andersen Hanne
Published: September 2024

Philosophy of science has developed immensely over the last half century. Subspecializations focused on particular scientific disciplines as well as generalist turns towards naturalization, practice, and engagement, not to mention an increasing internationalization, have all contributed to changing the practices of how philosophy of science is produced, published, and received, and to changing the relations between philosophy, philosophy of science, and science itself. This contribution to the Festschrift compiled in honor of Professor Finn Collin provides a brief sketch of these developments as seen through the prism of how Finn Collin as both a philosopher and a philosopher of science has contributed to these developments, nationally and internationally.
