Across time, space, and genres: measuring probabilistic grammar distances between varieties of Mandarin
Authors: Li Yi , Szmrecsanyi Benedikt , Zhang Weiwei 
Published: March 2024

Abstract
This paper aims to quantify distances between varieties of Mandarin (diachronic, regional, and situational) as a function of the similarity in the choice between syntactic variants in the Mandarin theme-recipient alternation (yŭ/gěi dative alternation). We use a novel corpus-based method, Variation-Based Distance and Similarity Modeling, which draws inspiration from work in comparative sociolinguistics and quantitative dialectometry. Analysis reveals that, while there is a relatively stable probabilistic grammar across the investigated varieties, historical varieties do exhibit a relatively higher degree of heterogeneity than synchronic varieties. Despite the overall high similarity of the latter, we identify substantial probabilistic differences between fictional writings of Modern Mainland Mandarin and all other synchronic varieties. Our findings thus provide evidence in support of the hypothesis that the transition from Early Mandarin to Modern Mandarin over the past two centuries has witnessed salient grammatical shifts and also empirically demonstrate the interaction between genre variability and regional variability in Modern Mandarin.

Em função da escassez futura dos combustíveis fósseis e a preocupação com o meio ambiente, a procura por fontes de energia alternativa vem crescendo. A energia solar fotovoltaica, que consiste na conversão da energia por meio da incidência dos raios solares nos painéis fotovoltaicos, tem crescido nos últimos anos devido à sua fácil aplicação, bem como ao fato de a sua fonte de energia, o Sol, ser “inesgotável”. No caso dessa geração de energia, especificamente, há um fator negativo que interfere diretamente na geração, pois pelo aspecto construtivo, por conta do tipo de instalação, os painéis ficam expostos na área externa (ao tempo) e sofrem com a interferência da poeira (sujidade), portanto faz-se necessário a implementação de rotinas de limpeza para minimizar a interferência desse agente. Assim, este estudo apresenta uma proposta de limpeza automatizada de sistemas fotovoltaicos e, após a instalação do mecanismo e dos testes realizados, verificou-se que, comparando com as mensurações quando o painel estava ligeiramente empoeirado, houve uma melhoria de desempenho de aproximadamente 25%, o que demonstra que o sistema se mostrou eficaz. De forma complementar, são apresentados os equipamentos necessários para a composição de um sistema fotovoltaico e os tipos de sistemas.

The texture of a rock or sediment is the size, shape, and arrangement of the grains. The microgeometry of sediments deals with intergranular relationship of grains, their size and shape. In the present study, a total of sixty surficial sediment samples were collected from the study area (foreshore-20, berm-7, backshore-13, and dunes-20) with an interval of 1 km. The geology, geomorphology, drainage pattern, climate, waves, and currents are discussed. The grain size parameters viz., mean grain size, standard deviation, skewness, and kurtosis are discussed extensively. Sand is the predominant component in all the sediment samples (99.82–99.93%) whereas silt and clay contents are less than 1% from the four environments. The mean grain size of the sediment samples shows that medium grained sands are followed by fine grained sands indicating a low energy environment of deposition. The standard deviation values reveal that the sediments are well to moderately sorted. The average values of skewness indicate that all the sediment samples are negatively skewed to positively skewed representing an environment of deposition of low to moderate energy conditions. Most of the kurtosis values indicate that the sediments are of platykurtic to leptokurtic in nature. The platykurtic nature of sediments indicates the sorting of tail portions of sediment populations.

OBJECTIVES
To evaluate the impact of implementing a stakeholder-informed social risk screening and social service referral system in a community hospital setting.

METHODS
We implemented a stakeholder-informed social care program at a community hospital in April 2022. The evaluation included patients aged 0 to 17 years admitted to the pediatric unit between April 2021 and March 2022 (1 year preimplementation) and between April 2022 and March 2023 (1 year postimplementation). For a random subset of 232 preimplementation and 218 postimplementation patients, we performed manual data extraction, documenting program process measures and preliminary effectiveness outcomes. We used χ square and Wilcoxon rank tests to compare outcomes between the preimplementation and postimplementation groups. Multivariable logistic regression was used to assess the preliminary effectiveness of the social care program in identifying social risks.

RESULTS
Screening rates were higher in the postimplementation group for nearly all social domains. Compared with preimplementation, the postimplementation group had higher rates of social risks identified (17.4% vs 7.8% [P &lt; .01]: adjusted odds ratio 2.9 [95% confidence interval 1.5–5.5]) on multivariate testing. Social work consults were completed more frequently and earlier for the postimplementation group (13.8.% vs 5.6% [P &lt; .01]) and median (19 hours vs 25 hours [P = .03]), respectively. Rates of communication of social risks in discharge summaries were higher in the postimplementation group (46.8% vs 8.2% [P &lt; .001]).

CONCLUSIONS
The implementation of a stakeholder-informed social care program within a community hospital setting led to the increased identification of social risks and social work consultations and improved timeliness of social work consultations and written communication of social risks in discharge summaries for primary care providers.

Published: March 2024

This article aims to understand better the mechanisms that connect climate change perceptions and general willingness to engage in environmental behavior in a sample of Spanish participants. To do this, we first developed and validated the General Willingness for Environmental Behavior Scale (GWEBS), which includes the classical approach of voluntarily doing new actions but also actions implying not doing things (decreasing) and actions forced by social constraints. Participants were n = 403. The exploratory and confirmatory factor analysis showed a good fit for the one-factor structure, which had adequate validity based on their relationship with other variables. In second place, the study found that eco-anxiety fully mediated the relationship between climate change perceptions and the GWEBS, making it a crucial variable to mobilize the intention to act following the perception. However, trust in science partially mediated the relationship between climate change perceptions and the GWEBS, suggesting that climate change perception and trust in science are essential. This study may provide a clear direction for future research and contributes to our understanding of the psychological mechanisms that drive pro-environmental behavior.

Abstract
This study investigates the effect of fluid type and stress shadow on proppant transport and the productivity of a multi-stage fractured Marcellus Shale horizontal well. Additionally, the relation between stress shadow and effective stress is studies to optimize fracture effectiveness. This study’s findings can be compared with similar study performed on a different Marcellus shale well. Furthermore, the extent to which various fracture properties contribute to production is evaluated. The available core plugs measurements, well logs, and the image logs were analyzed to determine the shale petrophysical and geomechanical properties including natural fracture (fissure) distribution to develop a model for Bogges-5H well. The available laboratory measurements and published data were analyzed to determine the gas adsorption characteristics and the shale compressibility. The impact of the shale compressibility was then incorporated in the model by developing multipliers for different compressibility components, i.e., fissure, matrix, and hydraulic fracture as function of net stress. A hydraulic fracture model was then coupled with the reservoir model. The combined model was employed to investigate the impact of fluid type, stress shadow, and stage spacing on proppant transport and the gas production.
The model’s credibility was confirmed by a close match between the actual and predicted production. The fracture heights induced by all the fluids remained within the pay zone and the entire fracture height contributed to the production. The High Viscosity Friction Reducer (HVFR) resulted in relatively larger fracture volume (increased fracture height) as compared to the Slickwater leading to improved productivity. The crosslinked gels also improved the productivity but were found to be inferior to HVFR. Stress shadow was found to influence the proppant transport and to impact the hydraulic fracture properties and gas production adversely. The adverse impact of the stress shadow on the production is more pronounced during early production due to higher production rates. The findings in this study can be used for fracture treatment design in the Marcellus shale by optimum fluid selection and the stage spacing to reduce the impact of the stress shadow.
Influence of adiabatic gravitational compression of atmospheric mass on the temperature of the troposphere
Authors: Michel THIZON 
Published: March 2024

Abstract
The temperature that the Earth's surface would have without the greenhouse effect, with an atmosphere completely transparent to infrared radiation, or even without an atmosphere at all, is generally estimated at -18°C. The greenhouse effect is estimated to induce a warming of 33°C to justify the surface temperature of +15°C. To explain this discrepancy, we examine, with the ideal gas law, to which the Earth's atmosphere obeys its normal conditions of pressure and temperature, the role that the adiabatic compression of the atmospheric mass subjected to gravity can play. The dimensional analysis of the ideal gas law demonstrates that compression of the atmosphere produces energy, which can be calculated in Joules. The temperature of the atmosphere near the Earth's surface is influenced by both its invariable atmospheric mass, solar irradiation and the greenhouse effect. This calls into question the commonly established Earth's Energy Budgets which consider almost exclusively radiative effects, and which deduce a Back Radiation attributed to the greenhouse effect which is abnormally high.

Published: March 2024

Abstract
The synthesis of signal-amplifying chemosensors induced by various triggers is a major challenge for multidisciplinary sciences. In this study, a signal-amplification system that was flexibly manipulated by a dynamic allosteric effector (trigger) was developed. Herein, the focus was on using the behavior of supramolecular polymerization to control the degree of polymerization by changing the concentration of a functional monomer (seed). It was assumed that this control was facilitated by a gradually changing/dynamic allosteric effector. A curved-π buckybowl sumanene and a sumanene-based chemosensor (SC) were employed as the seed/allosteric effector and the molecular binder, respectively. The hetero-supramolecular polymer, (SC•(sumanene)n), facilitated the manipulation of the degree of signal-amplification; this was accomplished by changing the sumanene seed concentration, which resulted in up to a 62.5-fold amplification of a steroid. The current results and the concept proposed herein provide an alternate method to conventional chemosensors and signal-amplification systems.

Published: March 2024

Abstract

The most widely used herbicide glyphosate contaminates surface waters around the globe. Being toxic to aquatic organisms and a possible carcinogenic, mitigation strategies attempt to reduce river contamination, but their impact is not evaluated. Investigating long-term time series, we discovered that – in contrast to the USA – glyphosate river water concentration patterns in Europe contradict a dominant input from herbicide application. Our large meta-analysis clearly shows that for decades, the main source of glyphosate has been municipal wastewater, visible in the close correlation to concentration patterns of, e.g., pharmaceuticals, rather high and constant loads all over the year and failure of mitigation strategies. We suspect that glyphosate enters European rivers as a transformation product of aminopolyphosphonates, which are used in European but not U.S. detergents.

Abstract

The X-linked A- variant (rs1050828, Val68Met) in G6PDX accounts for glucose-6-phosphate (G6PD) deficiency in approximately 11% of African American males. This common, hypomorphic variant may impact pulmonary host defense and phagocyte function during pneumonia by altering levels of reactive oxygen species produced by host leukocytes. We used CRISPR-Cas9 technology to generate novel mouse strain with “humanized” G6PD A- variant containing non-synonymous Val68Met single nucleotide polymorphism. Male hemizygous or littermate wild-type (WT) controls were inoculated intratracheally with K. pneumoniae (KP2 serotype, ATCC 43816 strain,103 CFU inoculum). We examined leukocyte recruitment, organ bacterial burden, bone marrow neutrophil and macrophage (BMDM) phagocytic capacity, and hydrogen peroxide (H2O2) production. Unexpectedly, G6PD-deficient mice showed decreased lung bacterial burden (p=0.05) compared to controls 24-h post-infection. Extrapulmonary dissemination and bacteremia were significantly reduced in G6PD-deficient mice 48-h post-infection. Bronchoalveolar lavage fluid (BALF) IL-10 levels were elevated in G6PD-deficient mice (p=0.03) compared to controls at 24-h but were lower at 48-h (p=0.03). G6PD A- BMDMs show mildly decreased in vitro phagocytosis of pHrodo-labeled KP2 (p=0.03). Baseline, but not stimulated, H2O2 production by G6PD A- neutrophils was greater compared to WT neutrophils. G6PD A- variant demonstrate higher basal neutrophil H2O2 production and are protected against acute Klebsiella intrapulmonary infection.
Predicting the variability of thermal runaway behavior of Li-ion cells with little to no calorimetry data
Authors: Finegan Donal , Masalkovaite Karina , Gasper Paul 
Published: March 2024

Abstract

Accurate measurement of the variability of thermal runaway behavior of lithium-ion cells is critical for designing safe battery systems. However, experimentally determining such variability is challenging, expensive, and time-consuming. Here, we utilize a transfer learning approach to accurately estimate the variability of heat output during thermal runaway using only ejected mass measurements and cell metadata, leveraging 139 calorimetry measurements on commercial lithium-ion cells available from the open-access Battery Failure Databank. We show that the distribution of heat output, including outliers, can be predicted accurately and with high confidence for new cell types using just 0 to 5 calorimetry measurements by leveraging behaviors learned from the Battery Failure Databank. Fractional heat ejection from the positive vent, cell body, and negative vent are also accurately predicted. We demonstrate that by using low cost and fast measurements, we can predict the variability in thermal behaviors of cells, thus accelerating critical safety characterization efforts.
Synergistic oxidation and adsorption of As(III) in water using biochar-mediated Fe(II)/nano-CaO2 system

Published: March 2024

Abstract

Due to its mobility and high toxicity, As(III) can easily migrate and accumulate through the food chain, endangering human health. The common treatment method for As(III) is a combination of oxidation and adsorption, in which the Fenton-like method exhibits a prominent removal performance. Based on our previous work, the Fe(II)/nano-CaO2/biochar Fenton-like system with excellent oxidizing and adsorption capabilities was used to remove As(III) from water. Compared to the common oxidation systems, the Fe(II)/nano-CaO2/RBC system showed an excellent As(III) removal through simultaneous oxidation and adsorption. The research findings demonstrated that under the cooperative effects of Fe(II) hydrolysis and RBC catalysis, As(III) in water could be efficiently removed in a broad initial 3.0–10.0 pH range, which solved the challenge of pH elevation that other metal peroxide systems encountered. In this system, most of the common co-existing cations and anions had no discernible impact on the As(III) elimination process, and some of the humic acid (HA) (< 60 mg L− 1) was mineralized simultaneously. Quenching and characterization experiments confirmed that •OH dominated the oxidation of As(III), and •OH production was boosted by the addition of RBC. The purification of oxidized As(V) from water can be achieved by binding it with Fe and Ca through the synthetic action of electrostatic adsorption, surface complexation, and co-precipitation. Overall, this work presents an alternative approach for effectively eliminating As(III) from water.
A Reversible Data Embedding Approach based on Inter-Channel Gradient Shifted MSB Predictor in Encrypted Images for Cloud Applications
Authors: Paul Selwyn , R Suchithra 
Published: March 2024

Abstract

The paper proposes an encrypted image-based reversible data embedding approach using an inter-channel gradient-shifted (IC-GS) MSB predictor for the application of cloud storage. In this approach, the data embedding was done on the cloud to store the encrypted images. Initially, the image was encrypted using permutation-based encryption by the user which is uploaded to the cloud. From the encrypted images, a primary channel and two secondary channels are estimated from which the gradient images are estimated. Using the histogram, the gradient images are estimated which is then shifted to perform embedding. Three different types of shifting approaches are proposed which include minimum value gradient shifting (MV-GS), threshold value gradient shifting (TV-GS), and maximum correlated gradient shifting (MC-GS). The gradient-shifted images are used to embed the data using the MSB predictor approach. The analysis of the algorithm was done using the standard color images obtained from the SIPI dataset and the evaluation was done with measures such as structural similarity index (SSI), peak signal-to-noise ratio, embedding rate, and entropy. The MC-GS gradient shifting results in an SSI, PSNR, and embedding rate of 0.1046, 8.13dB, and 2.832bpp respectively.

Abstract

This paper demonstrates the possibilities of the computer identification of individuals based on the digitized scent signatures using comprehensive two-dimensional gas chromatography with mass spectrometry (GCxGC-MS). This identification is performed by comparing an unknown digital scent sample (i.e., a chromatogram) with the digital scent signatures in the database.
The olfactronic (performed by computers) identification of persons will replace the olfactoric identification currently performed by trained police dogs. This olfactoric identification is considered to be only a subjective method and therefore it needs to be replaced by an objective olfactronic method. The results obtained in this study demonstrate the advantages of this objective olfactronic identification. In addition to this objectivity, the olfactronic identification method makes it possible to compare and store hundreds or even thousands of digital scent signatures in the database so that they do not change.
A higher recognition percentage of identification is achieved when applying two differently constructed signatures. The article shows that with this approach comparison algorithm can reach up to a 100-percent correct identification for unknown samples.
In this pilot study, 400 scent samples from 40 volunteers (20 women, 20 men) were analyzed by GCxGC-MS whereas ten scent samples were taken from each person.
