The Donkey King
Authors: Selove Emily
Published: November 2023

The 13th-century Arabic grimoire, al-Sakkākī's Kitāb al-Shāmil (Book of the Complete), provides numerous methods of contacting jinn. The first such jinn described, Abū Isrā'īl Būzayn ibn Sulaymān, arrives with a donkey. In the course of offering an explanation for his ritual, this Element reveals the double-sided nature of asinine symbology, and explains why this animal has served as the companion of both demons and prophets. Focusing on two nodes of donkey symbology—the phallus and the bray-it reveals a coincidentia oppositorum in a deceptively humble and comic animal form. Thus, the donkey, bearer of a demonic voice, and of a phallus symbolic of base materiality, also represents transcendence of the material and protection from the demonic. In addition to Arabic literature and occult rituals, the Element refers to evidence from the ancient Near East, Egypt, and Greece, as well as to medieval Jewish and Christian texts.
Chaucer and Becket's Mother
Authors: Pagès Meriem
Published: November 2023

Less than a hundred years after Thomas Becket's martyrdom at the hands of four of Henry II's knights, his Anglo-Norman mother was transformed into a pagan princess who abandoned faith and kin for Becket's father and Christianity. Pagès uses this wholly fictional legend about the saint to examine the place and function of conversion and mission in 'The Man of Law's Tale', juxtaposing the tale with the legend about Becket's mother to assess the power (or lack thereof) of baptism in late medieval English works. This new comparative study thus provides productive insights into the complexity of the emergence of the concept of race in medieval English culture and literature.
The meaning and form of onomatopoeias in Tjwao
Authors: Andrason Alexander , Phiri Admire , Fehn Anne-Maria
Published: November 2023

The present article analyzes the meaning and form of onomatopoeias in Tjwao, a Khoe-Kwadi (Kalahari Khoe) language. Making use of a prototype approach to categorization, a corpus of 113 onomatopoeic lexemes were tested for their compliance with the semantic, phonetic, and morphological features associated with the prototype of onomatopoeias in scholarly literature. The evidence demonstrates that Tjwao onomatopoeias tend to instantiate the prototype fully. This signifies, in turn, that, as far as their phonetics and morphology are concerned, Tjwao onomatopoeias tend to be extra-systematic.
Tracing the evolution of the gender of “COVID-19” in the French of three continents: A traditional and social media study
Authors: Dow Michael , Drouin Patrick
Published: November 2023

In this article, we document the gender of the noun “COVID-19” in a database of more than 76,000 tweets and in traditional media (approximately 500,000 articles) in French as spoken in Africa, (North) America and Europe. We find that North American media comply near-categorically with the recommendations of the feminine by the World Health Organization and local linguistic authorities in March 2020. The majority of North American tweets follow suit soon after. The African data show an increase of articles and tweets adopting the feminine after the Académie française's recommendation in May 2020. Finally, the feminine is negligible in the European data. We argue that among the factors at play are dialect-specific differences in French gender and loanword adaptation; the complex relationship among linguistic authorities, the public, and local media; and the relative delay in the Académie française's recommendation of the feminine.
Acquisition of English relative clauses by native speakers of Kurdish Sorani
Authors: Bahar Golpar
Published: November 2023

The present study investigates several linguistic factors that might be determinants of differences in the ease of acquisition of relative clauses (RCs) in L2 contexts, using the acquisition of English relative clauses by Kurdish Sorani native speakers. The analysis of 1440 subject and object RCs formed by Kurdish Sorani-speaking learners of English in a sentence combination task and a sentence translation task indicates that the syntactic functions of the noun phrase (NP) relativized in the RC, the position of the RC in the matrix clause (whether centre- or right-embedded), and the properties of RCs in L1 affect the acquisition and the formation of RCs in L2. The study also provides evidence that the syntactic functions of the relativized NP in the matrix clause, and the consistency/inconsistency of word orders in L1 and L2 do not influence the acquisition of RCs in L2.
Acquisition of kind-reference by Arabic, Chinese, and Turkish L2 learners of English
Authors: Köylü Yilmaz
Published: November 2023

This study examines the acquisition of kind-referring expressions such as The dodo is extinct. The objective is to investigate whether second language (L2) learners’ acquisition of nominal number marking and articles expressing kind-reference in English is affected by their first language (L1), their L2 proficiency in English, or the syntactic position of the kind-referring noun phrase (NP). L2 learners of English with Arabic, Chinese, and Turkish L1 backgrounds and a control group of native English speakers (NSs) participated in the study. The results from a Fill in the Gaps Task (FGT) and an Acceptability Judgment Task (AJT) demonstrated that L2 learners were more successful in their production and acceptability judgments when the expression of kind-reference in the target language was similar to that in their L1. The results also showed non-facilitative L1 transfer in the domain of bare singulars, as well as a positive effect of higher L2 proficiency on kind-referring NPs. Finally, the study revealed a subject/object asymmetry in the acquisition of kind-referring NPs in L2 English.
Connectivity Between Northern Iberia and Western France (2900–1100 cal bc): The Flux of Metalwork in the Bay of Biscay Modelled by Multivariate Clustering
Authors: Latorre-Ruiz Juan
Published: November 2023

Connections between northern Iberia and western France around the Bay of Biscay during the Chalcolithic, Early Bronze Age, and Middle Bronze Age are addressed in this article through a multivariate cluster analysis of a dataset of 1273 metal finds, comprising 4554 metal artefacts grouped into five multiregional clusters with distinctive distributions, chronologies, content, and contexts. Changes in distribution and chronology show that metalwork from faraway regions was deposited in similar ways, reflecting changing patterns of interregional connectivity. Changes in context and content suggest social transformations. The clustering method known as Latent Class Analysis is presented here in the hope that it will be applicable to other datasets elsewhere in the world.
A normative model for Bayesian combination of subjective probability estimates
Authors: Trick Susanne , Rothkopf Constantin A. , Jäkel Frank
Published: November 2023

Combining experts’ subjective probability estimates is a fundamental task with broad applicability in domains ranging from finance to public health. However, it is still an open question how to combine such estimates optimally. Since the beta distribution is a common choice for modeling uncertainty about probabilities, here we propose a family of normative Bayesian models for aggregating probability estimates based on beta distributions. We systematically derive and compare different variants, including hierarchical and non-hierarchical as well as asymmetric and symmetric beta fusion models. Using these models, we show how the beta calibration function naturally arises in this normative framework and how it is related to the widely used Linear-in-Log-Odds calibration function. For evaluation, we provide the new Knowledge Test Confidence data set consisting of subjective probability estimates of 85 forecasters on 180 queries. On this and another data set, we show that the hierarchical symmetric beta fusion model performs best of all beta fusion models and outperforms related Bayesian fusion models in terms of mean absolute error.
Working memory capacity and the risky-choice framing effect: A preregistered replication and extension of Corbin et al. ()
Authors: Bogdanov Boris , Corbin Jonathan , Dobreva Sabina , McElroy Todd , Rachev Nikolay R.
Published: November 2023

While working memory capacity is associated with superior performance on a number of tasks, could it paradoxically sometimes be associated with suboptimal performance? Corbin et al. (2010, Judgment and Decision Making 5(2), 110–115) found that, in a between-subjects design, higher WMC is associated with a larger risky-choice framing effect, traditionally conceived of as a departure from rational principles. Such surprising findings are of potentially great theoretical importance; yet the original study was underpowered. In this registered report, we aimed to replicate and extend the original findings, by conducting an online experiment among 425 North Americans. To extend the findings beyond the specific single tasks used in the original study, we used three WMC tasks with different processing components and six framing problems involving human lives. In a close replication, the frame significantly interacted with neither the Ospan short absolute score nor the Ospan short partial score in predicting ratings on the disease-framing problem. Similarly, in an extended replication, a composite WMC score did not significantly interact with the frame in predicting ratings on three framing problems involving human lives. The Bayes factors showed that the data were 3 to 10 times more likely under the null hypothesis of no interaction between WMC and frame. Taken together, these findings show an absence of association between the between-subjects risky-choice framing effect and WMC. This outcome is compatible with four out of the six theoretical accounts we considered, and is uniquely predicted by the default-interventionist dual-process account and the pragmatic inference account. Further research can more rigorously pit conflicting predictions of these accounts against each other.
Direct numerical simulation-based vibroacoustic response of plates excited by turbulent wall-pressure fluctuations
Authors: Prajapati Soham , Anantharamu Sreevatsa , Mahesh Krishnan
Published: November 2023

We use direct numerical simulation to study the vibroacoustic response of an elastic plate in a turbulent channel at

$Re_\tau$

of 180 and 400 for three plate boundary conditions and two materials – synthetic rubber and stainless steel. The fluid–structure–acoustic coupling is assumed to be one-way coupled, i.e. the fluid affects the solid and not vice versa, and the solid affects the acoustic medium and not vice versa. The wall pressure consists of intermittent large-amplitude fluctuations associated with the near-wall, burst-sweep cycle of events. For stainless steel plates, displacement has similar large-amplitude peak events due to comparable time scales of plate vibration and near-wall eddies. For synthetic rubber plates, large-amplitude displacement fluctuations are observed only near clamped or simply supported boundaries. Away from boundaries, plate displacement resembles an amplitude-modulated wave, and no large-amplitude events are observed. We discuss displacement and acoustic pressure spectra over different frequency ranges. For frequencies much smaller than the first natural frequency, the product of plate-averaged displacement spectrum and bending stiffness squared collapses with Reynolds number and plate material in outer units. At high frequencies, displacement and acoustic pressure spectra scale better in inner units, and the scaling depends on the type of damping. For synthetic rubber plates, the spectra display an overlap region that collapses in both outer and inner units. Soft plate deformation displays a range of length scales. However, stiff plate deformation does not exhibit a similar range of scales and resembles plate mode shapes. The soft plate has two distinct deformation structures. Low-speed, large deformation structures with slow formation/break-up time scales are found away from boundaries. High-speed, small deformation structures with fast formation/break-up time scales formed due to boundary reflections exist near the boundaries.
Transition to turbulence in wind-drift layers
Authors: Wagner Gregory LeClaire , Pizzo Nick , Lenain Luc , Veron Fabrice
Published: November 2023

A light breeze rising over calm water initiates an intricate chain of events that culminates in a centimetres-deep turbulent shear layer capped by gravity–capillary ripples. At first, viscous stress accelerates a laminar wind-drift layer until small surface ripples appear. The surface ripples then catalyse the growth of a second instability in the wind-drift layer, which eventually sharpens into along-wind jets and downwelling plumes, before devolving into three-dimensional turbulence. In this paper, we compare laboratory experiments with simplified, wave-averaged numerical simulations of wind-drift layer evolution beneath monochromatic, constant-amplitude surface ripples seeded with random initial perturbations. Despite their simplicity, our simulations reproduce many aspects of the laboratory-based observations – including the growth, nonlinear development and turbulent breakdown the wave-catalysed instability – generally validating our wave-averaged model. But we also find that the simulated development of the wind-drift layer is disturbingly sensitive to the amplitude of the prescribed surface wave field, such that agreement is achieved through suspiciously careful tuning of the ripple amplitude. As a result of this sensitivity, we conclude that wave-averaged models should really describe the coupled evolution of the surface waves together with the flow beneath to be regarded as truly ‘predictive’.
Association between micronutrients intake and metabolic-associated fatty liver disease: a cross-sectional study based on the National Health and Nutrition Examination Survey
Authors: Hou Jun-zhen , Wu Qi-wei , Zhang Li
Published: November 2023

Metabolic-associated fatty liver disease (MAFLD) has been proposed to replace the term non-alcoholic fatty liver disease (NAFLD) in 2020. The association between micronutrients and MAFLD has not been reported. Therefore, this study aims to explore the association between micronutrients intake and MAFLD. This was a cross-section study based on the National Health and Nutrition Examination Survey (NHANES). The dietary intake of copper, zinc, iron, and selenium was evaluated using the 24-h dietary recall interview. Logistic regression analysis was used to explore the association between micronutrients and MAFLD, and the results were shown as odds ratio (OR) with 95 % confidence intervals (CIs). A total of 5976 participants were finally included for analysis, with 3437 participants in the MAFLD group. After adjusting potential confounders, copper intake at quartile Q3 (OR = 0⋅68, 95 % CI 0⋅50, 0⋅93) and Q4 (OR = 0⋅60, 95 % CI 0⋅45, 0⋅80) was found to be associated with lower odds of MAFLD. Iron intake at Q2 (OR = 0⋅64, 95 % CI 0⋅45, 0⋅92) and Q3 (OR = 0⋅61, 95 % CI 0⋅41, 0⋅91) was associated with the lower odds of MAFLD. Our findings found that high intake of copper and adequate intake of iron were associated with MAFLD, which may provide guidance for the management of MAFLD.
Effect of substrate salinity and pH on life history traits of the bluetongue virus vectorCulicoides peregrinus
Authors: Banerjee Paramita , Sarkar Ankita , Mazumdar Abhijit
Published: November 2023

Habitat selection ofCulicoidesspp. (Diptera: Ceratopogonidae) is influenced by the physicochemical factors such as temperature, pH, salinity, moisture, conductivity, organic and inorganic compounds of substrates. These factors determine the life history traits of the vectors. We studied the influence of substrate salinity (0–40 parts per thousand, ppt) and pH (pH 1–13) on oviposition, egg hatching, larval survivability, and adult emergence ofCulicoides peregrinusKieffer under laboratory conditions. Most eggs (80.74%) were laid in 0 ppt and 95% in pH 7 but lowered with increased salinity and pH levels. It was observed that the females did not lay eggs in 30 ppt to 40 ppt salinity; pH 1 and pH 13 but interestingly up to 95% of the eggs were retained within the abdomen. Little effect of salinity and pH on egg hatching was observed up to 5 ppt and 10 ppt except at the extreme values of 40 ppt and pH 1, pH 13. Pupation did not occur in rearing plates with high salinities, 30 ppt and 40 ppt, although the few eggs hatched when exposed to such salinity. In low salinity (0 to 2 ppt), occurrence of adult emergence was more and then decreased with increasing salinity. Maximum emergence was seen when the rearing media was alkaline. This study deals with the suitability of breeding substrate ofC. peregrinuswhen exposed to salinity and pH ranges. Our study suggests the ambient salinity and pH ranges to be maintained during laboratory rearing of this vector species.
Political Polarisation and the Constitutional Crisis in Israel
Authors: Porat Iddo
Published: November 2023

The article aims to further the understanding of the current constitutional crisis in Israel through the lens of political polarisation. Israel, like other countries around the world, is experiencing a substantial increase in political polarisation. Recent data shows that since 2009 affective polarisation (the extent to which individuals have negative feelings towards members of the opposing party or group and positive feelings towards their own party or group) has risen by 180 per cent. The article discusses the various phenomena associated with an increase in polarisation and the problems it raises, traces the reasons for the increase in polarisation in Israel, and argues that polarisation has played an important role in creating the conflict between the current government and the Supreme Court, and in making it so intense and intractable.
Weather indices during reproductive phase explain wheat yield variability
Authors: Zeleke Ketema Tilahun , Anwar Muhuddin , Emebiri Livinus , Luckett David
Published: November 2023

When water and nutrients are not limiting, and pests and disease are effectively controlled, crop growth and yield is determined by weather conditions such as temperature and solar radiation. To determine the relationship between weather indices and crop yield, multiple wheat varieties were sown at two sowing times, for five sowing seasons and at two locations. The following weather indices around the 50% anthesis stage were recorded and analysed: mean temperature (Tmean), maximum temperature (Tmax), number of days with temperature >30°C (T30), vapour pressure deficit (VPD), photosynthetically active radiation, photothermal quotient (PQ) and photothermal quotient corrected for vapour pressure deficit (PQvpd). Overall, for every 1°C rise in temperature, crop yield decreased by 370 kg/ha. For every 1°C rise in temperature, normal sowing window yield decreased by 360 kg/ha while late-sown wheat yield decreased by 640 kg/ha. Correlation analysis was conducted between the weather indices and grain number, grain yield and grain protein. There was a significant positive correlation between PQ and PQvpd and grain number and grain yield. There was a significant negative correlation between Tmean, Tmax, T30 and VPD and grain number and grain yield. Grain protein content showed a positive correlation with maximum air temperature and a negative correlation with the weather indices PQ and PQvpd. PQ and PQvpd can be used to predict grain number and grain yield potential. This study showed that grain number and grain yield predicted using PQ and PQvpd are more reliable than using temperature and radiation individually.

Background

COVID-19 lockdowns increased the risk of mental health problems, especially for children with autism spectrum disorder (ASD). However, despite its importance, little is known about the protective factors for ASD children during the lockdowns.

Methods

Based on the Shanghai Autism Early Developmental Cohort, 188 ASD children with two visits before and after the strict Omicron lockdown were included; 85 children were lockdown-free, while 52 and 51 children were under the longer and the shorter durations of strict lockdown, respectively. We tested the association of the lockdown group with the clinical improvement and also the modulation effects of parent/family-related factors on this association by linear regression/mixed-effect models. Within the social brain structures, we examined the voxel-wise interaction between the grey matter volume and the identified modulation effects.

Results

Compared with the lockdown-free group, the ASD children experienced the longer duration of strict lockdown had less clinical improvement (β = 0.49, 95% confidence interval (CI) [0.19–0.79], p = 0.001) and this difference was greatest for social cognition (2.62 [0.94–4.30], p = 0.002). We found that this association was modulated by parental agreeableness in a protective way (−0.11 [−0.17 to −0.05], p = 0.002). This protective effect was enhanced in the ASD children with larger grey matter volumes in the brain's mentalizing network, including the temporal pole, the medial superior frontal gyrus, and the superior temporal gyrus.

Conclusions

This longitudinal neuroimaging cohort study identified that the parental agreeableness interacting with the ASD children's social brain development reduced the negative impact on clinical symptoms during the strict lockdown.
Pretreatment cognitive performance is associated with differential self-harm outcomes in 6 v. 12-months of dialectical behavior therapy for borderline personality disorder
Authors: Traynor Jenna M. , McMain Shelley , Chapman Alexander L. , Kuo Janice , Labrish Cathy , Ruocco Anthony C.
Published: November 2023

Background

Recent findings suggest that brief dialectical behavior therapy (DBT) for borderline personality disorder is effective for reducing self-harm, but it remains unknown which patients are likely to improve in brief v. 12 months of DBT. Research is needed to identify patient characteristics that moderate outcomes. Here, we characterized changes in cognition across brief DBT (DBT-6) v. a standard 12-month course (DBT-12) and examined whether cognition predicted self-harm outcomes in each arm.

Methods

In this secondary analysis of 240 participants in the FASTER study (NCT02387736), cognitive measures were administered at pre-treatment, after 6 months, and at 12 months. Self-harm was assessed from pre-treatment to 2-year follow-up. Multilevel models characterized changes in cognition across treatment. Generalized estimating equations examined whether pre-treatment cognitive performance predicted self-harm outcomes in each arm.

Results

Cognitive performance improved in both arms after 6 months of treatment, with no between-arm differences at 12-months. Pre-treatment inhibitory control was associated with different self-harm outcomes in DBT-6 v. DBT-12. For participants with average inhibitory control, self-harm outcomes were significantly better when assigned to DBT-12, relative to DBT-6, at 9–18 months after initiating treatment. In contrast, participants with poor inhibitory control showed better self-harm outcomes when assigned to brief DBT-6 v. DBT-12, at 12–24 months after initiating treatment.

Conclusions

This work represents an initial step toward an improved understanding of patient profiles that are best suited to briefer v. standard 12 months of DBT, but observed effects should be replicated in a waitlist-controlled study to confirm that they were treatment-specific.
Zeros, chaotic ratios and the computational complexity of approximating the independence polynomial
Authors: DE BOER DAVID , BUYS PJOTR , GUERINI LORENZO , PETERS HAN , REGTS GUUS
Published: November 2023

The independence polynomial originates in statistical physics as the partition function of the hard-core model. The location of the complex zeros of the polynomial is related to phase transitions, and plays an important role in the design of efficient algorithms to approximately compute evaluations of the polynomial.

In this paper we directly relate the location of the complex zeros of the independence polynomial to computational hardness of approximating evaluations of the independence polynomial. We do this by moreover relating the location of zeros to chaotic behaviour of a naturally associated family of rational functions; the occupation ratios.
Two early layers of Sanctus melodies
Authors: PFISTERER ANDREAS
Published: November 2023

This article examines Sanctus melodies from the tenth and eleventh centuries with special attention to the division of the first verbal phrase. The melodies with circulation in all regions of the Roman rite fall into two groups, an earlier one with ternary division and a later one with binary division. This picture is further enriched by the analysis of melodies connected in some way with these widespread melodies, by the simple melodies of the Sundays and weekdays and by an overview over northern French melodies of the eleventh and twelfth centuries.

Published: November 2023

Ziziphus lotus is an underappreciated natural genetic resource widespread in Algeria. This study aimed to compare the fruit phytochemical composition of nine populations of Z. lotus from different areas to highlight its diversity. Fruits were harvested from the semiarid, dry steppe and Saharan stages. Primary and secondary metabolites and minerals contents were determined. Significant variations in the fruit phytochemical composition between populations of Z. lotus and between pulp and seeds were recorded. Z. lotus is dry fruit with 8.768 ± 0.449 to 13.468 ± 1.303% water in pulp and 6.7 to 12.12% in seeds. Significantly higher values were recorded in the fruit pulp for sugar (35.25 to 48.87%), phosphorus (63.114 to 155.269 mg 100−1g), sodium (34.8 to 56.91 ppm), calcium (91.78 to 382.69 ppm), β-carotene (36.4 to 46 μg g−1), lycopene (59.15 to 100.25 μg g−1) and chlorophyll a (3.6 to 7.2 μg g−1) contents. Seeds had much higher protein (8.37 to 27.75%), lipid (35.39 to 48.01%), potassium (125.874 to 325.408 mg. 100−1 g), polyphenol (439.465 to 1349.46 mg.GAE.100 g−1), flavonoid (83.908 to 98.259 mg.QE.100 g−1), tannins (55.268 to 277.94 mg.GAE.100 g−1) and chlorophyll b (11.2 to 30.4 μg g−1) contents. Bougtob, Boghar and Mougheul populations had higher primary metabolites and mineral values. Oued Nougued, Maarif and Mougheul populations were the richest in phenolic compounds. Oued Nougued, Maarif and Mougheul populations had more liposoluble pigments. This research is the beginning of investigating the variety of Z. lotus as phylogenetic sources. Further comparative investigations over a larger distribution region and further study of variations in the composition in fruit composition using GC-MS are needed.
Smooth pigweed (Amaranthus hybridus) and unresolved Amaranthus spp. from Brazil resistant to glyphosate exhibit the EPSPS TAP-IVS substitution

Published: November 2023

The presence of glyphosate-resistant smooth pigweed (Amaranthus hybridus L.) biotypes has increased in southern Brazil in recent years, presenting the triple amino acid substitution TAP-IVS in 5-enol-pyruvylshikimate-3-phosphate synthase (EPSPS) previously found in Argentina. Some of these biotypes have morphological characteristics of A. hybridus and redroot amaranth (Amaranthus retroflexus L.). The present study aimed to identify, through molecular markers, the herbicide-resistant species of Amaranthus from Brazil that have the TAP-IVS substitution and to analyze the occurrence of pollen-mediated gene flow (PMGF) as the source of the TAP-IVS substitution in these biotypes. Six biotypes were evaluated using internal transcribed spacer (ITS) sequences, of which two (AMACHY-S and CAMAQ-R) were molecularly classified as A. hybridus and four (AMACRET-S, AMACVI-S, ARRGR-R, and SAOJER-R) were unclassified. Interestingly, all the glyphosate-resistant biotypes (ARRGR-R, SAOJER-R, and CAMAQ-R) had the TAP-IVS substitution and an increase in EPSPS relative copy number; however, only CAMAQ-R was confirmed as A. hybridus. Although the biotypes ARRGR-R and SAOJER-R are closely related to A. hybridus and green pigweed (Amaranthus powellii S. Watson), their species identity could not be resolved. The biotype SAOJER-R also was resistant to acetolactate synthase (ALS)-inhibiting herbicides due to a tryptophan to leucine substitution at position 574 in ALS. The evaluation of 119,746 seedlings in an intraspecific hybridization study of A. hybridus indicated an outcrossing frequency of 0.09%. In contrast, an absence of interspecific hybridization (A. hybridus × unclassified biotype, AMACVI-S) was found after screening 111,429 offspring. Unclassified biotypes might be derived from one or more ancient hybridization events and subsequently evolved the triple mutation independently. Alternatively, such biotypes could have evolved from recent hybridization events, which occur at a frequency below the level of detection in our study.
Water‐Induced Mantle Overturns Leading to the Origins of Archean Continents and Subcontinental Lithospheric Mantle
Authors: Wu Zhongqing , Song Jian , Zhao Guochun , Pan Zhongxu
Published: November 2023

The origins of Archean continents and subcontinental lithospheric mantle (SCLM) were important events in the early Earth. The mechanisms for the origins of Archean continents and the SCLM remain unclear. This study suggests that these events were controlled by the evolution of the hydrous magma ocean (MO). With solidification, the basal MO eventually became gravitationally unstable because of the enrichment of water. The triggered massive mantle overturns resulted in the major pulses of the crust and thick SCLM generations. The model avoids a fatal drawback of the oceanic plateau model for the origin of continents: the source of H2O needed for the formation of tonalite‐trondhjemite‐granodiorite (TTG). The model can also account for why the TTG and thick SCLM basically occurred in the Archean.

Optical gain enhancement of two-dimensional CsPbBr3 nanosheets was studied when the amplified spontaneous emission is guided by a patterned structure of polyurethane-acrylate. Given the uncertainties and pitfalls in retrieving a gain coefficient from the variable stripe length method, a gain contour $$g(\hslash \omega ,x)$$

was obtained in the plane of spectrum energy (ℏω) and stripe length (x), whereby an average gain was obtained, and gain saturation was analysed. Excitation and temperature dependence of the gain contour show that the waveguide enhances both gain and thermal stability due to the increased optical confinement and heat dissipation, and the gain origins were attributed to the two-dimensional excitons and the localized states.

Published: November 2023

We, for the first time, report the nanoscopic imaging study of anomalous infrared (IR) phonon enhancement of bilayer graphene, originated from the charge imbalance between the top and bottom layers, resulting in the enhancement of E1u mode of bilayer graphene near 0.2 eV. We modified the multifrequency atomic force microscope platform to combine photo-induced force microscope with electrostatic/Kelvin probe force microscope constituting a novel hybrid nanoscale optical-electrical force imaging system. This enables to observe a correlation between the IR response, doping level, and topographic information of the graphene layers. Through the nanoscale spectroscopic image measurements, we demonstrate that the charge imbalance at the graphene interface can be controlled by chemical (doping effect via Redox mechanism) and mechanical (triboelectric effect by the doped cantilever) approaches. Moreover, we can also diagnosis the subsurface cracks on the stacked few-layer graphene at nanoscale, by monitoring the strain-induced IR phonon shift. Our approach provides new insights into the development of graphene-based electronic and photonic devices and their potential applications.

Published: November 2023

Residual stress engineering is widely used in the design of new advanced lightweight materials. For metallic glasses, attention has been given to structural changes and rejuvenation processes. High-energy scanning X-ray diffraction strain mapping reveals large elastic fluctuations in notched metallic glasses after deformation under triaxial compression. Microindentation hardness mapping hints at a competing hardening–softening mechanism after compression and reveals the complementary effects of stress and structure modulation. Transmission electron microscopy proves that structure modulation and elastic heterogeneity distribution under room temperature deformation are related to shear band formation. Molecular dynamics simulations provide an atomistic understanding of the confined deformation mechanism in notched metallic glasses and the related fluctuations in the elastic and plastic strains. Thus, future focus should be given to stress modulation and elastic heterogeneity, which, together with structure modulation, may allow the design of metallic glasses with enhanced ductility and strain-hardening ability.

Engineering an efficient semiconductor to sustainably produce green hydrogen via solar-driven water splitting is one of the cutting-edge strategies for carbon-neutral energy ecosystem. Herein, a superhydrophilic green hollow ZnIn2S4 (gZIS) was fabricated to realize unassisted photocatalytic overall water splitting. The hollow hierarchical framework benefits exposure of intrinsically active facets and activates inert basal planes. The superhydrophilic nature of gZIS promotes intense surface water molecule interactions. The presence of vacancies within gZIS facilitates photon energy utilization and charge transfer. Systematic theoretical computations signify the defect-induced charge redistribution of gZIS enhancing water activation and reducing surface kinetic barriers. Ultimately, the gZIS could drive photocatalytic pure water splitting by retaining close-to-unity stability for a full daytime reaction with performance comparable to other complex sulfide-based materials. This work reports a self-activated, single-component cocatalyst-free gZIS with great exploration value, potentially providing a state-of-the-art design and innovative aperture for efficient solar-driven hydrogen production to achieve carbon-neutrality.

The worldwide extinction of megafauna during the Late Pleistocene and Early Holocene is evident from the fossil record, with dominant theories suggesting a climate, human or combined impact cause. Consequently, two disparate scenarios are possible for the surviving megafauna during this time period - they could have declined due to similar pressures, or increased in population size due to reductions in competition or other biotic pressures. We therefore infer population histories of 139 extant megafauna species using genomic data which reveal population declines in 91% of species throughout the Quaternary period, with larger species experiencing the strongest decreases. Declines become ubiquitous 32–76 kya across all landmasses, a pattern better explained by worldwide Homo sapiens expansion than by changes in climate. We estimate that, in consequence, total megafauna abundance, biomass, and energy turnover decreased by 92–95% over the past 50,000 years, implying major human-driven ecosystem restructuring at a global scale.

The spatial organisation of cellular protein expression profiles within tissue determines cellular function and is key to understanding disease pathology. To define molecular phenotypes in the spatial context of tissue, there is a need for unbiased, quantitative technology capable of mapping proteomes within tissue structures. Here, we present a workflow for spatially-resolved, quantitative proteomics of tissue that generates maps of protein abundance across tissue slices derived from a human atypical teratoid-rhabdoid tumour at three spatial resolutions, the highest being 40 µm, to reveal distinct abundance patterns of thousands of proteins. We employ spatially-aware algorithms that do not require prior knowledge of the fine tissue structure to detect proteins and pathways with spatial abundance patterns and correlate proteins in the context of tissue heterogeneity and cellular features such as extracellular matrix or proximity to blood vessels. We identify PYGL, ASPH and CD45 as spatial markers for tumour boundary and reveal immune response-driven, spatially-organised protein networks of the extracellular tumour matrix. Overall, we demonstrate spatially-aware deep proteo-phenotyping of tissue heterogeneity, to re-define understanding tissue biology and pathology at the molecular level.

Color and motion are used by many species to identify salient objects. They are processed largely independently, but color contributes to motion processing in humans, for example, enabling moving colored objects to be detected when their luminance matches the background. Here, we demonstrate an unexpected, additional contribution of color to motion vision in Drosophila. We show that behavioral ON-motion responses are more sensitive to UV than for OFF-motion, and we identify cellular pathways connecting UV-sensitive R7 photoreceptors to ON and OFF-motion-sensitive T4 and T5 cells, using neurogenetics and calcium imaging. Remarkably, this contribution of color circuitry to motion vision enhances the detection of approaching UV discs, but not green discs with the same chromatic contrast, and we show how this could generalize for systems with ON- and OFF-motion pathways. Our results provide a computational and circuit basis for how color enhances motion vision to favor the detection of saliently colored objects.

The transformation from one compound to another involves the breaking and formation of chemical bonds at the single-bond level, especially during catalytic reactions that are of great significance in broad fields such as energy conversion, environmental science, life science and chemical synthesis. The study of the reaction process at the single-bond limit is the key to understanding the catalytic reaction mechanism and further rationally designing catalysts. Here, we develop a method to monitor the catalytic process from the perspective of the single-bond energy using high-resolution scanning tunneling microscopy single-molecule junctions. Experimental and theoretical studies consistently reveal that the attack of a halogen atom on an Au atom can reduce the breaking energy of Au−S bonds, thereby accelerating the bond cleavage reaction and shortening the plateau length during the single-molecule junction breaking. Furthermore, the distinction in catalytic activity between different halogen atoms can be compared as well. This study establishes the intrinsic relationship among the reaction activation energy, the chemical bond breaking energy and the single-molecule junction breaking process, strengthening our mastery of catalytic reactions towards precise chemistry.

An effective human immunodeficiency virus type I (HIV-1) vaccine that robustly elicits broadly neutralizing antibodies (bnAbs) against HIV-1 envelope glycoproteins (Envs) to block viral entry is still not available. Thus, identifying triggers for elicitation of different types of anti-HIV-1 Env antibodies by vaccination could provide further guidance for immunogen design and vaccine development. Here, we studied the immune response to HIV-1 Env immunogens in rabbits. We show that sequential immunizations with conformation-specific Env immunogens can elicit low titer but broad neutralization responses against heterologous, neutralization-resistant (tier 2/3) transmitted/founder (T/F) HIV-1 strains. More importantly, an mRNA vaccine candidate that could mediate the presentation of a cytoplasmic tail-deleted (ΔCT) HIV-1AD8 Env immunogen on virus-like particles significantly increased the neutralization response. This strategy shifted the type of elicited antibodies, decreasing the level of binding to soluble Envs while significantly increasing their overall viral neutralization activity. The breadth and potency of neutralizing response against heterologous, T/F HIV-1 strains significantly increased in a subset of rabbits. Efficient neutralization activity was associated with high cellular immune responses specific to HIV-1 Envs. These results help to understand the immune response to different immunization schemes and will allow developing new approaches to selectively manipulate the type of humoral immune response by specific vaccination.

Transferable and mechanistic understanding of cross-scale interactions is necessary to predict how coastal systems respond to global change. Cohesive datasets across geographically distributed sites can be used to examine how transferable a mechanistic understanding of coastal ecosystem control points is. To address the above research objectives, data were collected by the EXploration of Coastal Hydrobiogeochemistry Across a Network of Gradients and Experiments (EXCHANGE) Consortium – a regionally distributed network of researchers that collaborated on experimental design, methodology, collection, analysis, and publication. The EXCHANGE Consortium collected samples from 52 coastal terrestrial-aquatic interfaces (TAIs) during Fall of 2021. At each TAI, samples collected include soils from across a transverse elevation gradient (i.e., coastal upland forest, transitional forest, and wetland soils), surface waters, and nearshore sediments across research sites in the Great Lakes and Mid-Atlantic regions (Chesapeake and Delaware Bays) of the continental USA. The first campaign measures surface water quality parameters, bulk geochemical parameters on water, soil, and sediment samples, and physicochemical parameters of sediment and soil.

Augmented Reality in education can support students in a wide range of cognitive tasks–fostering understanding, remembering, applying, analysing, evaluating, and creating learning-relevant information more easily. It can help keep up engagement, and it can render learning more fun. Within the framework of a multi-year investigation encompassing primary and secondary schools across Europe, the ARETE project developed several Augmented Reality applications, providing tools for user interaction and data collection in the education sector. The project developed innovative AR learning technology and methodology, validating these in four comprehensive pilot studies, in total involving more than 2,900 students and teachers. Each pilot made use of a different Augmented Reality application covering specific subjects (English literacy skills, Mathematics and Geography, Positive Behaviour, plus, additionally, an Augmented Reality authoring tool applied in a wide range of subjects). In this paper, we introduce the datasets collected during the pilots, describe how the data enabled the validation of the technology, and how the approach chosen could enhance existing augmented reality applications in data exploration and modelling.
