Published: May 2024

In recent years, various data-driven algorithms have been applied to the classification and staging of brain glioma MRI detection. However, the restricted availability of brain glioma MRI data in purely data-driven deep learning algorithms has presented challenges in extracting high-quality features and capturing their complex patterns. Moreover, the analysis methods designed for 2D data necessitate the selection of ideal tumor image slices, which does not align with practical clinical scenarios. Our research proposes an novel brain glioma staging model, Medical Cognition Embedded (MCE) model for 3D data. This model embeds knowledge characteristics into data-driven approaches to enhance the quality of feature extraction. Approach includes the following key components: (1) Deep feature extraction, drawing upon the imaging technical characteristics of different MRI sequences, has led to the design of two methods at both the algorithmic and strategic levels to mimic the learning process of real image interpretation by medical professionals during film reading; (2) We conduct an extensive Radiomics feature extraction, capturing relevant features such as texture, morphology, and grayscale distribution; (3) By referencing key points in radiological diagnosis, Radiomics feature experimental results, and the imaging characteristics of various MRI sequences, we manually create diagnostic features (Diag-Features). The efficacy of proposed methodology is rigorously evaluated on the publicly available BraTS2018 and BraTS2020 datasets. Comparing it to most well-known purely data-driven models, our method achieved higher accuracy, recall, and precision, reaching 96.14%, 93.4%, 97.06%, and 97.57%, 92.80%, 95.96%, respectively.

Introduction

Hyperphosphatemia and hyperparathyroidism are common in end-stage kidney disease and are associated with poor outcomes. In addition to adequate dialysis, medications are usually required for optimum control of serum phosphate and parathyroid hormone (PTH) levels. The use of calcium-based phosphate binders (CBPBs) and active vitamin D is associated with an increase in serum calcium and worsening vascular calcification. To overcome these limitations, non-calcium-based phosphate binders (NCBPBs) and calcimimetics have been developed. However, the coverage for these new medications remains limited in several parts of the world due to the lack of patient-level outcome data and cost. The present study examined the differences in mineral outcomes between two main categories of healthcare programs that provided different coverage for medications used to control mineral and bone disorders (MBD). The Social Security/Universal Coverage (SS/UC) program covered only CBPBs and active vitamin D, whereas the Civil Servant/State Enterprise (CS/SE) program provided coverage of CBPBs, active vitamin D, NCBPBs, and calcimimetics.

Methods

This 10-year retrospective cohort study examined the differences in mineral outcomes between two healthcare programs in maintenance hemodialysis patients. The differences in serum calcium, phosphate, and PTH levels, as well as the aortic arch calcification score, were analyzed according to dialysis vintage by linear mixed-effects regression analyses. The difference in the composite outcome of severe hyperparathyroidism and parathyroidectomy was analyzed by the Cox-proportional hazard regression model.

Results

714 patients were included in the analyses (full cohort). Of these patients, 563 required at least one type of medication to control MBD (MBD medication subgroup). Serum calcium, phosphate, and the proportions of patients with hypercalcemia and hyperphosphatemia were substantially higher in the SS/UC group compared with the CS/SE group after appropriate adjustments for confounders in both the full cohort and the MBD medication subgroup. These findings were confirmed in propensity-score matched analyses. Higher parathyroid hormone levels and a higher rate of the composite endpoint of severe hyperparathyroidism and parathyroidectomy were also observed in the SS/UC group. A more rapid progression of aortic arch calcification was suggested in the SS/UC group, but between-group changes were not significant.

Conclusion

Patients under the healthcare program that did not cover the use of NCBPBs and calcimimetics showed higher serum calcium and phosphate levels and a more rapid progression of hyperparathyroidism. The difference in the progression of vascular calcification could not be confirmed in the present study.

Comportamento intraempreendedor e cultura organizacional intraempreendedora: Uma análise sobre a influência no sucesso de projetos
Authors: Elias Tatiana Carneiro da Cunha de , Martens Cristina Dai Prá , Bizarrias Flávio Santino
Published: May 2024

Objetivo: apesar do grande interesse acadêmico e prático sobre o intraempreendedorismo, são poucos os estudos que o relacionam ao sucesso de projetos. O objetivo deste estudo é determinar a influência moderadora da cultura organizacional intraempreendedora sobre o comportamento intraempreendedor e suas relações com o sucesso do projeto. O estudo objetiva ainda estabelecer os perfis heterogêneos de intraempreendedorismo e seus diferentes efeitos sobre o sucesso de projetos. Método: utilizou-se como abordagem um survey, com análise dos dados por modelagem de equações estruturais, regressão linear para os testes de moderação, e análise de classes latentes para a classificação heterogênea da amostra de 284 participantes de projetos em termos de intraempreendedorismo. Contribuições teóricas: os resultados demonstram que há influência do intraempreendedorismo dos profissionais no sucesso de projetos. Por outro lado, uma cultura organizacional intraempreendedora fraca ou mediana, reduz a força da relação do intraempreendedorismo com o sucesso de projetos. O estudo identifica ainda três perfis heterogêneos de intraempreendedores, e que a cultura organizacional eleva a possibilidade de sucesso do projeto, mesmo para indivíduos com baixo perfil para intraempreendedorismo. Originalidade: este estudo analisa pioneiramente a relação entre intraempreendedorismo individual e organizacional, como cultura, para o sucesso de projetos, direta e indiretamente, com uma metodologia diversificada. Contribuições para a gestão: o estudo sugere, para a prática, a importância do comportamento intraempreendedor para o sucesso dos projetos, e a relevância do estímulo à cultura organizacional intraempreendedora, capaz de mobilizar até mesmo indivíduos pouco empreendedores, na medida em que indivíduos naturalmente intraempreendedores são escassos.
Charge Transfer Complexes of 1-Cyclohexylpiperazine as Donor with 2,3-Dichloro-5,6-dicyano-p-benzoquinone and 2,3,5,6-Tetra chloro-p-benzoquinone as Acceptors: A Comparative Studies of Spectroscopic, Thermodynamic and DFT Analysis

Published: May 2024

Novel 1-cyclohexylpiperazine charge transfer compounds, acting as donors, were investigated in conjunction with the π-acceptors 2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ) and 2,3,5,6-tetrachloro-p-benzoquinone (CHL) through spectrophotometric analysis at room temperature in acetonitrile. The Benesi-Hildebrand equation was applied to determine the molar extinction coefficient (ε) and stability constant (KCT) for both charge transfer (CT) complexes, each exhibiting a 1:1 molar composition. The infrared (IR) spectroscopy confirmed the presence of CT complexes and these complexes were further evaluated for their pharmacological potential in DNA binding studies, revealing their interaction with DNA through intercalation. The density functional theory (DFT) analysis provided insights into bond lengths, bond angles, Mulliken atomic charges, molecular electrostatic potential (MEP) maps and the highest occupied molecular orbital to the lowest unoccupied molecular orbital (HOMO-LUMO) characteristics of the CT complexes.
Assessment of Influences on the Early Age Concrete Strength Development
Authors:   , Kasal Pavel
Published: May 2024

The thesis deals with the influences of concrete mix design changes and common deviations during concrete production on the regression relationship of the maturity method, which represents the compressive strength development of the specific concrete mix design and is a basis for nondestructive monitoring of early-age compressive strength. The main aim is to get more insights into the behaviour of regression relationships, which the standard calls the calibration curve, in response to changes in the concrete mix design or deviation during concrete production. It should allow easier usage of the maturity method, which is used in practice more often. The research was divided into several phases. The tests started in the laboratory environment, which provided more precise results as a preparation for tests in practice. Then, the investigation of different concrete mix design changes and their influences continued on the concrete plant, which already offers valid practical results. One of the last phases took place directly on the construction site and investigated the deviations in practice during the actual concrete pouring within two seasons. Those results provide transparent information about the accuracy of the maturity method applied in practice.
La unidad del Padre y el Hijo (y el Espíritu) en los Padres Apostólicos. Un recorrido
Authors: Sanvito Clara
Published: May 2024

El artículo estudia cómo los Padres Apostólicos (Didaché, Epístola del Pseudo-Bernabé, Clemente de Roma, Ignacio de Antioquía, El pastor de Hermas, la segunda carta de Clemente, A Diogneto) concibieron y expresaron la unidad entre Padre, Hijo y, donde aparezca, Espíritu. Del análisis de sus textos, aun con diferencias, emerge una sustancial convergencia: estos autores profesan con claridad el monoteísmo y a la vez conciben Padre, Hijo y Espíritu (o, en su caso, Padre e Hijo) unidos. Divisan, pues, en Dios una pluralidad, que expresan de diferentes maneras. Por ejemplo, insistiendo en que el Hijo es Dios, definiendo de modo particular su generación, mostrando la sinergia de los tres en el obrar, aunque todavía no conceptúan con precisión la realidad trinitaria.
Consustancialidad e inhabitación en el pensamiento cristológico de Hilario de Poitiers. ¿Influencia nicena o íntima comprensión del Cuarto Evangelio?
Authors: Alba López Almudena
Published: May 2024

Sabemos, por él mismo, que Hilario de Poitiers, no tuvo conocimiento del credo de Nicea hasta 356. A pesar de esto, desde su primera obra conocida, la adhesión de Hilario de Poitiers a los planteamientos fundamentales que definirán la correcta comprensión de la naturaleza de Cristo resulta incontestable. Esto se debe a que parte, en su reflexión cristológica, de una íntima comprensión del Evangelio de Juan que antepone a la mera defensa del homooúsios niceno. A través de la exégesis de los pasajes y motivos más relevantes del Cuarto Evangelio, Hilario de Poitiers explora la relación entre Padre e Hijo profundizando en su carácter consustancial y en la inhabitación mutua de sus Personas, imprimiendo un carácter pneumatológico a su reflexión cristológica y demostrando un conocimiento profundo de la naturaleza del Cristo que trasciende, con mucho, la mera especulación en torno a su familiaridad con el credo de Nicea y con el homooúsios.
En busca de un pensamiento social cristiano comparativo. Una propuesta metodológica
Authors: Villagrán Gonzalo
Published: May 2024

El artículo “En busca de un pensamiento social cristiano comparativo” busca proponer una metodología para elaborar un pensamiento social cristiano comparado. Para ello explora dos fuentes de inspiración: la subdisciplina de la ética religiosa comparada, propia de la ciencia de las religiones, y la corriente de la teología comparativa. La ética religiosa comparada ofrece una potente reflexión teórica sobre el problema de un método para la comparabilidad y la teología comparativa permite reinterpretar ese método para garantizar el carácter teológico y confesional de éste. Tomando elementos de ambas fuentes y combinándolos podemos presentar un método suficientemente sistematizado que parta de categorías de comparación propias del pensamiento político que se iluminen en la mirada comparada entre el cristianismo y otras tradiciones religiosas.

Linear scores and measures of both udder and teat shape and size (thirteen traits) were assessed in 83 ewes of Improved Valachian breed (IV) and in crossbreds with East Friesian breed (EF 25% or EF 50%). At the same time, cistern measures and cross-section areas (fourteen traits) as well as milk yield and milkability were scanned using ultrasound technique or measured in the same individuals (130 measurements in each trait). Crossbreds with EF 50% had the largest udders in terms of depth, width, and height, as determined by either a nine-point linear score or exact measurements. Additionally, these crossbreds had teats that were more horizontally placed and the most appropriate udder attachment and shape. more horizontally and most appropriate udder attachment and shape. Ultrasound scans revealed that the areas of both the left and right udder cisterns scanned by ultrasound were the highest in EF 50% crosses. Overall cistern cross-section areas scanned from the side were 2934.6 mm2 in IV, 2932.6 mm2 in crosses of EF 25% and 3559.4 mm2 in crosses of EF 50% (P<0.05). Crossbreds of EF 50% had more appropriate machine milked milk and total milk yield (311.1 and 424.7 ml) than purebred IV (231.8 and 336.1 ml; P>0.05). On average, the proportion of machine-stripped milk was 33.2%, and non-significant influence of genotype was shown. Furthermore, all traits under study showed non significant differences between crosses of EF 25% and 50%.

Published: May 2024

Disease outbreaks are partly the direct result of the expansion of poultry flocks. To understand farmers’ behaviours, their awareness of highly pathogenic avian influenza (HPAI), the study was con ducted. A total of 150 farms in three districts of Tra Vinh Province were included. Purposive sampling was used to choose respondents who have at least 20 poultry heads and a three-year operation. Descrip tive and multiple regression analyses were used to analyze data. The findings indicated that most farm ers (65.3%) were males with an average age of 50 years. Farmers received < $100/month from poultry production. The farm scale of poultry business was less than 100 heads per farmer, and birds were reared traditionally, using by-products, floor feeding, and no automatic watering systems. Selling broil ers dominated, whereas egg sales were uncommon and were generally reserved for domestic use. In addition, farmers were aware of HPAI prevention (>90% were, poor knowledge that was not validat ed). Additionally, farmers' awareness significantly increased by the enhancement in education, training, income, and full-time employment at poultry farms. It can be concluded that the small-scale poultry farming employs traditional practices with a keen awareness of infectious diseases. However, to raise farmers' awareness, strategies should concentrate on profession, education, training, and income.
InferDB: In-Database Machine Learning Inference Using Indexes
Authors: Salazar-Díaz Ricardo , Glavic Boris , Rabl Tilmann
Published: May 2024

The performance of inference with machine learning (ML) models and its integration with analytical query processing have become critical bottlenecks for data analysis in many organizations. An ML inference pipeline typically consists of a preprocessing workflow followed by prediction with an ML model. Current approaches for in-database inference implement preprocessing operators and ML algorithms in the database either natively, by transpiling code to SQL, or by executing user-defined functions in guest languages such as Python. In this work, we present a radically different approach that approximates an end-to-end inference pipeline (preprocessing plus prediction) using a light-weight embedding that discretizes a carefully selected subset of the input features and an index that maps data points in the embedding space to aggregated predictions of an ML model. We replace a complex preprocessing workflow and model-based inference with a simple feature transformation and an index lookup. Our framework improves inference latency by several orders of magnitude while maintaining similar prediction accuracy compared to the pipeline it approximates.
AAA: An Adaptive Mechanism for Locally Differentially Private Mean Estimation
Authors: Wei Fei , Bao Ergute , Xiao Xiaokui , Yang Yin , Ding Bolin
Published: May 2024

Local differential privacy
(
LDP
) is a strong privacy standard that has been adopted by popular software systems, including Chrome, iOS, MacOS, and Windows. The main idea is that each individual perturbs their own data locally, and only submits the resulting noisy version to a data aggregator. Although much effort has been devoted to computing various types of aggregates and building machine learning applications under LDP, research on fundamental perturbation mechanisms has not achieved significant improvement in recent years. Towards a more refined result utility, existing works in the literature mainly focus on improving the
worst-case
guarantee. However, this approach does not necessarily promise a better
average
performance given the fact that the data in practice obey a certain distribution, which is not known beforehand.

In this paper, we propose the
advanced adaptive additive
(
AAA
) mechanism, which is a distribution-aware approach that addresses the average utility and tackles the classical
mean estimation
problem. AAA is carried out in a two-step approach: first, as the global data distribution is not available beforehand, the data aggregator selects a random subset of individuals to compute a (noisy) quantized data descriptor; then, in the second step, the data aggregator collects data from the remaining individuals, which are perturbed in a distribution-aware fashion. The perturbation involved in the latter step is obtained by solving an optimization problem, which is formulated with the data descriptor obtained in the former step and the desired properties of task-determined utilities. We provide rigorous privacy proofs and utility analyses, as well as extensive experiments comparing AAA with state-of-the-art mechanisms. The evaluation results demonstrate that the AAA mechanism consistently outperforms existing solutions with a clear margin in terms of result utility, on a wide range of privacy constraints and real-world and synthetic datasets.
Fast Local Subgraph Counting
Authors: Li Qiyan , Yu Jeffrey Xu
Published: May 2024

We study local subgraph counting queries,Q= (p, o), to count how many times a givenk-node pattern graphpappears around every nodeυin a data graphGwhen the given center nodeoinpmaps toυ.Such local subgraph counting becomes important in GNNs (Graph Neural Networks), where incorporating such counts for every node inGinto the GNN architecture enhances the model's ability to capture complex relationships within the graphG.It is challenging to count by subgraph isomorphism, which is known to be NP-hard. In this paper, we propose a novel approach by tree-decomposition-based counting. For a complex pattern graphpinQ, we find its best tree decompositionT, where a node inTrepresents a subgraph ofp, and a node inpmay appear in multiple nodes inT.Letp(T) be the pattern represented byT.Our approach is to countp(T) by homomorphism with a constraint to count the subgraph in every tree node by subgraph isomorphism. We apply symmetry-breaking rules to reduce the cost of counting by subgraph isomorphism for every node inT, and we develop a new multi-join algorithm to compute such counts. We confirm that our approach on a single machine using a single core can outperform the others significantly.
Everything You Always Wanted to Know About Storage Compressibility of Pre-Trained ML Models but Were Afraid to Ask
Authors: Su Zhaoyuan , Ahmed Ammar , Wang Zirui , Anwar Ali , Cheng Yue
Published: May 2024

As the number of pre-trained machine learning (ML) models is growing exponentially, data reduction tools are not catching up. Existing data reduction techniques are not specifically designed for pre-trained model (PTM) dataset files. This is largely due to a lack of understanding of the patterns and characteristics of these datasets, especially those relevant to data reduction and compressibility.

This paper presents the first, exhaustive analysis to date of PTM datasets on storage compressibility. Our analysis spans different types of data reduction and compression techniques, from hash-based data deduplication, data similarity detection, to dictionary-coding compression. Our analysis explores these techniques at three data granularity levels, from model layers, model chunks, to model parameters. We draw new observations that indicate that modern data reduction tools are not effective when handling PTM datasets. There is a pressing need for new compression methods that take into account PTMs' data characteristics for effective storage reduction.

Motivated by our findings, we design Elf, a simple yet effective, error-bounded, lossy floating-point compression method. Elf transforms floating-point parameters in such a way that the common exponent field of the transformed parameters can be completely eliminated to save storage space. We develop Elves, a compression framework that integrates Elf along with several other data reduction methods. Elves uses the most effective method to compress PTMs that exhibit different patterns. Evaluation shows that Elves achieves an overall compression ratio of 1.52×, which is 1.31×, 1.32× and 1.29× higher than a general-purpose compressor (zstd), an error-bounded lossy compressor (SZ3), and the uniform model quantization, respectively, with negligible model accuracy loss.
Contributions Estimation in Federated Learning: A Comprehensive Experimental Evaluation
Authors: Chen Yiwei , Li Kaiyu , Li Guoliang , Wang Yong
Published: May 2024

Federated Learning (FL) provides a privacy-preserving and decentralized approach to collaborative machine learning for multiple FL clients. The contribution estimation mechanism in FL is extensively studied within the database community, which aims to compute fair and reasonable contribution scores as incentives to motivate FL clients. However, designing such methods involves challenges in three aspects: effectiveness, robustness, and efficiency. Firstly, contribution estimation methods should utilize the data utility information of various client coalitions rather than that of individual clients to ensure effectiveness. Secondly, we should beware of adverse clients who may exploit tactics like data replication or label flipping. Thirdly, estimating contribution in FL can be time-consuming due to enumerating various client coalitions.

Despite numerous proposed methods to address these challenges, each possesses distinct advantages and limitations based on specific settings. However, existing methods have yet to be thoroughly evaluated and compared in the same experimental framework. Therefore, a unified and comprehensive evaluation framework is necessary to compare these methods under the same experimental settings. This paper conducts an extensive survey of contribution estimation methods in FL and introduces a comprehensive framework to evaluate their effectiveness, robustness, and efficiency. Through empirical results, we present extensive observations, valuable discoveries, and an adaptable testing framework that can facilitate future research in designing and evaluating contribution estimation methods in FL.
Art, pictoriality and semiotics – a reflection on Göran Sonesson’s contribution to art theory
Authors: Sandin Gunnar
Published: May 2024

This reflection on Göran Sonesson’s writings and theoretical engagement in art is also a survey of a set of semiotic concepts related to this area. As a semiotician Sonesson wrote about varying sub-genres like fine art, photography, film and architecture. The reflection is also a personal recollection – as a colleague, friend and participant in the Lund circle of semiotics – of ideas and discussions highlighting the relation between semiotics, art theory and artistic practice. This reflection captures a couple of notions of importance in Sonesson’s contributions to semiotic theory relating to pictoriality, art and culture, such as “secondary iconicity”, “projected Ego, Alter and Alius”, “sedimentation of impressions”, “picture subject and picture object”, etc. The reflection ends in stating the importance of the specifically Lifeworld-based semiotic contribution by Sonesson to art theory, a contribution perhaps yet to be fully appreciated, and how this contribution also corresponds with how practicing artists reach out to, but also goes beyond, the art world itself.
Multi-source symbiosis of textual meaning
Authors: Zeng Jun
Published: May 2024

In both Chinese and Western literary theory, there are several fundamental perspectives on the exploration of “the source of textual meaning,” which can be categorized into ontological, entitative, and generative types. Future research must integrate the “source” perspective with the “trigger” perspective, while overcoming the postmodern cultural pluralist limitations of “multiple symbiosis.” This article adopts the perspective of a “multi-source symbiosis” of textual meaning and maintains that textual meaning possesses characteristics of multiple sources, co-generation, and dynamic transformation. The “multi-source symbiosis” of textual meaning does not emphasize “differences,” but rather strives for “consensus.” The objectivity of the source of textual meaning and the regularity of textual understanding and interpretation are the prerequisites for agreement on textual meaning. The trigger mechanism for the symbiosis of textual meanings lies in three aspects: disclosing textual meanings in reading behavior, proliferating textual meanings in critical activities, and multi-source triggering of textual meanings in literary events. “Multi-source symbiosis” creates a heteroglossic state of textual meaning, with the ultimate goal of establishing a common understanding of textual meaning.
Abai’s poetry in Eco’s semiotic light
Authors: Khassenova Roza , Sarkulova Manifa
Published: May 2024

The article explores the poetry of Abai Qunanbaiuly, a renowned philosopher and a founder of modern Kazakh literature, through the semiotic perspective of Umberto Eco. The study is a part of a broader research project in cultural studies titled “Semiotic Interpretation of Culture by Umberto Eco.” Specifically, the poem under analysis is “Allanyn özi de ras, sözi de ras” (“Allah is truth, His word is truth”), written in 1902. While Abai’s works initially garnered great enthusiasm, they now provoke heated discussions within Kazakh society. By applying a semiotic approach, this study offers a fresh perspective on Abai’s poetry, enabling new insights and interpretations.
Indexical order and language ideology in the linguistic landscape of tourism in Hong Kong: Chungking Mansions and its surroundings
Authors: Wang Jinjun , Liang Zihui
Published: May 2024

This study undertakes an investigation into the linguistic landscape of tourism in the tourist areas of Chungking Mansions and its surrounding environs in Hong Kong and intends to reveal similarities and differences in the linguistic signs in the two areas by employing a statistical analysis of a comprehensive database of public signs. The results show that official signs in the two areas prioritize the use of Chinese and English, and Chinese has a marginally higher representation in the surrounding areas. In contrast, private signs in Chungking Mansions exhibit a distinctive linguistic diversity, with over 20 languages represented, and English occupying dominant position, followed by Arabic, Hindi, and other languages. In the surrounding areas, private signs are displayed in eight languages, with Chinese being the predominant code, followed by English, Japanese, Korean, and other languages. It is found that the linguistic landscape of tourism in Hong Kong is diversified, contextualized by historical, political, cultural, and economic factors, and characterized by indexical ordering and ideological implications, and English plays a crucial role in distinguishing Hong Kong from other Chinese cities. In addition, the study offers insights into the complexity and importance of linguistic diversity in the context of tourism and urban development.

Artificial intelligence-driven education evaluation and scoring: Comparative exploration of machine learning algorithms
Authors: Ma Xiangfen
Published: May 2024

With the widespread popularity of intelligent education, artificial intelligence plays an important role in the field of education. Currently, there are issues such as low accuracy and low adaptability. By comparing algorithms such as logistic regression, decision tree, random forest (RF), support vector machine, and long short-term memory (LSTM) recurrent neural network (RNN), this article adopted a multi-classification fusion strategy and fully considered the adaptability of the algorithm to evaluate and grade students in two scenarios with different grades and teaching quality. By encoding and normalizing student grades, six evaluation parameters were selected for the evaluation criteria of teaching quality through principal component analysis feature selection. Multi-classifier models were used to fuse the five models in pairs, improving the accuracy of the experimental evaluation. Finally, the experimental data of the six fused multi-classification models in the scenarios of student performance estimation and teaching quality estimation were compared, and the experimental effects of education evaluation and grading under different models were analyzed. The experimental results showed that the LSTM RNN-RF model had the strongest adaptability in the scenario of student performance estimation, with an estimation accuracy of 98.5%, which was 12.9% higher than a single RF model. This experiment was closely related to educational scenarios and fully considered the adaptability of different machine learning algorithms to different scenarios, improving the prediction and classification accuracy of the model.
Adaptive fabric with emissivity regulation for thermal management of humans
Authors: Li Xiansheng , Liu Meiling , Chen Ken , Li Lanxin , Pei Gang , Zhao Bin
Published: May 2024

The heat generation of the human body dramatically varies between resting and active status, so dynamic heat dissipation is required to ensure optimal thermal comfort. Herein, we propose a spectrally self-adaptive smart fabric (SSSF) by covering polyester fabric with silver nanowires, which autonomously adjusts its emissivity in response to the body’s movement status from dry to wet states. During periods of inactivity, the SSSF maintains radiative heat insulation with a low emissivity state of 0.39. Conversely, during vigorous physical activity, its emissivity is improved to 0.83 when the sweat penetrates the SSSF, facilitating greater heat dissipation. Comparative experiments demonstrate the superior thermal management capabilities of the SSSF, with a 19.5 % reduction in heat dissipation power relative to traditional fabrics when in the low emissivity mode, and an impressive 67.6 % enhancement in heat dissipation power as it changes from low to high emissivity mode. This work provides an adaptive approach to emissivity modulation, offering an effective solution for dynamic heat dissipation of humans across various states of activity, thereby enhancing personal thermal comfort.
Framing the Reading Experience of an Apocryphal Text: The Case of the 1 Apocryphal Apocalypse of John’s Titles
Authors: Cardozo Mindiola Cristian Daniel
Published: May 2024

It has long been recognized that paratexts – those liminal features that accompany the main text in a book – perform a primary role in interpretation since they mediate the text to the readers. They function like a commentary, trying to influence and guide readers to a better comprehension of the text. At the same time, they are artifacts of reception because in the pre-modern period, paratexts are the product of scribes and reading communities. Thus, by studying paratexts, one can have access to how the text was received and how readers shape the reading practices of subsequent users. The study of paratexts in the field of biblical studies has been a booming area of research, while the study of these features in the so-called apocryphal literature is only in its dawn. This article intends to help to remedy the situation by studying the titles of the1 Apocryphal Apocalypse of John. Since this text exerted a huge amount of influence in shaping the eschatological imagination of many Christians in Late Antiquity and given the scarce amount of information that we have on its reception, studying the paratexts of the manuscripts – titles, specifically – is the safest bet to recover its reception/interpretation and the reading practices of its readers. Based on the study of1 Apocr. Apoc. John’stitles, this article concludes that (1)1 Apocr. Apoc. Johnwas read as an apocalypse; that is, readers thought that the text mediated hitherto unknown divine knowledge; (2) readers of1 Apocr. Apoc. Johnbelieved that it was an authentic work of John the apostle and thus authoritative and true; (3) readers were guided to navigate1 Apocr. Apoc.

Amid resurgent geopolitical fissures and in the aftermath of the Covid-19 pandemic, there is a growing awareness in the sector of the need for, and concern about, national and international collaboration in archaeological projects. This article reflects on present-day challenges for international collaboration in central Eurasian archaeology and furthers a much-needed discussion about (re)integrating local narratives with inter-regional trends in future research. Responsible and practical proposals for bridging collaborator differences in institutional or publishing obligations, language capacities and access to resources are discussed.

Alzheimer's disease (AD) is characterized by an initial decline in declarative memory, while nondeclarative memory processing remains relatively intact. Error-based motor adaptation is traditionally seen as a form of nondeclarative memory, but recent findings suggest that it involves both fast, declarative, and slow, nondeclarative adaptive processes. If the declarative memory system shares resources with the fast process in motor adaptation, it can be hypothesized that the fast, but not the slow, process is disturbed in AD patients. To test this, we studied 20 early-stage AD patients and 21 age-matched controls of both sexes using a reach adaptation paradigm that relies on spontaneous recovery after sequential exposure to opposing force fields. Adaptation was measured using error clamps and expressed as an adaptation index (AI). Although patients with AD showed slightly lower adaptation to the force field than the controls, both groups demonstrated effects of spontaneous recovery. The time course of the AI was fitted by a hierarchical Bayesian two-state model in which each dynamic state is characterized by a retention and learning rate. Compared to controls, the retention rate of the fast process was the only parameter that was significantly different (lower) in the AD patients, confirming that the memory of the declarative, fast process is disturbed by AD. The slow adaptive process was virtually unaffected. Since the slow process learns only weakly from an error, our results provide neurocomputational evidence for the clinical practice of errorless learning of everyday tasks in people with dementia.

The Arctic is sensitive to cloud radiative forcing. Due to the limited number of aerosols present throughout much of the year, cloud formation is susceptible to the presence of cloud condensation nuclei and ice nucleating particles (INPs). Primary biological aerosol particles (PBAP) contribute to INPs and can impact cloud phase, lifetime, and radiative properties. We present yearlong observations of hyperfluorescent aerosols (HFA), tracers for PBAP, conducted with a Wideband Integrated Bioaerosol Sensor, New Electronics Option during the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition (October 2019–September 2020) in the central Arctic. We investigate the influence of potential anthropogenic and natural sources on the characteristics of the HFA and relate our measurements to INP observations during MOSAiC. Anthropogenic sources influenced HFA during the Arctic haze period. But surprisingly, we also found sporadic “bursts” of HFA with the characteristics of PBAP during this time, albeit with unclear origin. The characteristics of HFA between May and August 2020 and in October 2019 indicate a strong contribution of PBAP to HFA. Notably from May to August, PBAP coincided with the presence of INPs nucleating at elevated temperatures, that is, >−9°C, suggesting that HFA contributed to the “warm INP” concentration. The air mass residence time and area between May and August and in October were dominated by the open ocean and sea ice, pointing toward PBAP sources from within the Arctic Ocean. As the central Arctic changes drastically due to climate warming with expected implications on aerosol–cloud interactions, we recommend targeted observations of PBAP that reveal their nature (e.g., bacteria, diatoms, fungal spores) in the atmosphere and in relevant surface sources, such as the sea ice, snow on sea ice, melt ponds, leads, and open water, to gain further insights into the relevant source processes and how they might change in the future.

The greenstone belts in the Middle Dnipro Domain of the Ukrainian Shield comprise sedimentary-volcanogenic rocks of the Konka and Bilozerka Groups separated by a unconformity. The Konka Group is composed mainly of volcanic rocks varying in composition from ultrabasic to felsic composition with subordinate sedimentary rocks, while the Bilozerka Group is composed of sedimentary rocks with a small amount of felsic volcanic rocks. Three associations of ferruginous-siliceous rocks have been identified in the greenstone rocks of the Middle Dnipro Domain. These are the ferruginous-siliceous-mafic and ferruginous-siliceous-keratophyre (schist-jaspilite-tholeiite) associations in the Konka Group and the transitional ferruginous-siliceous-shale to ferruginous-siliceous-keratophyre association in the Bilozerka Group, which many researchers compare with the ferruginous-siliceous formations of Kryvyi Rih Group. The rocks of the early ferruginous-siliceous-mafic association (Konka Group) are found among the volcanogenic rocks with a komatiite-tholeiitic association. These rocks are intruded by 3.08-3.0 Ga-old plagioclase granites of the Sura Complex. In the younger ferruginous-siliceous-keratophyre (schist-jaspilite-tholeiite) association (Bilozerka Group), ferruginous-siliceous deposits are interlayered with sedimentary and tuffaceous rocks and reach a thickness of up to 350 m. The Chortomlyk iron ore deposit, which is located in the Chortomlyk Greenstone Belt, is confined to this rock association. The ages of the iron-bearing rocks has not been constrained to date. We dated 60 detrital zircon grains from quartz-amphibole schists sampled at a section of sedimentary-volcanogenic rocks of the Chortomlyk deposit. Fifty-three analyzed crystals yielded an age of 3.08-3.12 Ga; six crystals were dated at 3.08-3.06 Ga, and one crystal at 3.18 Ga. They all have low U contents (1.4-20 ppm), while the Th/U ratio falls in the range of 0.3-0.9, indicating a likely magmatic origin. Sedimentary-volcanogenic rocks of the Chortomlyk iron ore deposit could been formed on a marine shelf near uplifted highs of plagioclase granites of the Sura Complex (dated at 3.08-3.06 Ga), or near volcanoes of the same age. Thus, the sedimentary-volcanogenic rocks of the Chortomlyk iron deposit are younger than the rocks of the Konka Group. Similar detrital zircon ages were previously obtained from the ferruginous-siliceous association of the Bilozerka Group in the Bilozerka Greenstone Belt (3.05 Ga) and the Vysokopillya Greenstone Belt (3.06 Ga). Thus, the ferruginous-siliceous-mafic association formed before the plagioclase granites of the Sura Complex, while the ferruginous-siliceous-keratophyre (schist-jaspilite-tholeiite) association was formed after the emplacement of the plagioclase granites.
