Evolving graph based knowledge space model for tutoring systems
Authors: Csépányi-Fürjes László , Kovács László 
Published: August 2024

AbstractAn intelligent tutoring system is a computer-based educational tool designed to provide adaptive learning environment to learners, mimicking the role of a human tutor. Its most typical areas of application are language learning, mathematics education, programming courses and medical training. Intelligent Tutoring Systems are based on the knowledge-module that is holding the system's knowledge in a well-structured format. Considering the current state of the art knowledge-module representations, a model that can represent evolving information is lacking. Representing evolving information is needed for those tutoring systems that are working with dynamically changing domains, e.g., software science. In this paper a new combined model is presented that is based on the ontology model and the fundamentals of knowledge space theory. The proposed model introduces the term of abstract time to be able to formulate an evolving knowledge graph. This paper introduces the term of evoking-hooks that makes it possible to realize connections between external domain elements and the nodes of the proposed model.

Existe uma relação retroalimentativa entre o trabalho editorial e as políticas editoriais que desempenha importante papel operacional nas atividades científicas envolvendo autores, editores, avaliadores, agências de fomento à pesquisa, bases indexadoras de periódicos, entre outros agentes. Nesse sentido, uma definição específica e consensual do conceito de políticas editoriais pode contribuir com a regulamentação da publicação científica. Esse trabalho teve como objetivo analisar a relação entre as informações disponibilizadas nos sites de periódicos da área de Educação e suas políticas editoriais, bem como, definir um conceito de “políticas editoriais”. Nesta pesquisa de paradigma interpretativo e caráter qualitativo, foi realizada uma análise documental e temática das informações disponibilizadas nos sites de cinco periódicos do estrato A1 do Qualis CAPES. Os dados foram organizados em três principais categorias: sobre a revista, fluxo editorial e questões éticas. A partir disso, foi proposta uma definição de “políticas editoriais” de caracteres normativo, técnico e político, que, ao reivindicar caráter consensual, pode contribuir para a operacionalidade do trabalho editorial e para a tomada de decisões nas atividades relacionadas à publicação científica.

Along with the introduction of new froth separation sections at new and existing enterprises, the basis for increasing the output of small diamonds is the reduction of their losses at the existing froth separation sections. The results of the studies of diamond surface composition under conditions of technogenic hydrophilization made it possible to establish the influence of the effects of crystallization of carbonate and silicate mineral films and the fixation of sludge fractions on the hydrophobicity and floatability of diamonds. It was proposed to use combined regimes of conditioning of ore and recycled water to increase floatability of diamonds, providing removal of hydrophilizing coatings and restoration of natural hydrophobicity of diamonds. The application of methods of acoustic, thermal, electrochemical, and reagent treatment of water-mineral disperse systems, as well as their combinations to increase floatability and reduce losses of hydrophilic diamonds in the process of froth separation was considered and substantiated.Based on the study of the effect of the temperature factor in the preparation and froth separation processes, the optimal temperature regime of froth separation cycle operations was substantiated, providing the use of the heat consumed for thermal treatment of the initial diamond-containing material at a temperature of 85–90°С to maintain the required temperature in the conditioning operations with a collector and immediately in the froth separation and flotation operations.It was shown that the regulation of phase composition of an apolar collector by additives of low- and medium- molecular fractions provides increase of its collecting ability due to transition of asphaltene-resin fraction into adhesion-active form and occurrence of processes of the collector autodispergating in aqueous phase. On the basis of the statistical analysis of froth separation process indicators depending on changing the share of recycled water in the processes the reason for worsening the indicators (performance) was determined, which consisted in a significant increase in the concentration of sludges. The optimum degree of recycled water use (85%) was determined, which ensures decreasing the used collector consumption by 8% without decreasing diamond recovery and concentrate quality.

Published: August 2024

ABSTRACTThe study of Deccan volcano-sedimentary successions is significant for understanding the palaeomagnetic correlation, eruption history and palaeoenvironmental conditions of the Central India during the Cretaceous-Paleogene (K-Pg) transition. In this study, we applied an integrated magnetostratigraphic and sedimentological approach to the Deccan Intertrappean Succession exposed at the Mothi Hill (Malwa Subprovince), Sagar, to provide palaeomagnetic age constraints for the lava flows, depositional environment and end-Cretaceous palaeogeography. Palaeo-magnetic data suggest that the lower and upper Trap lava flows associated with the Mothi Intertrappean deposits are not coeval, and they correspond to C29r and C29n magnetochrons, respectively, which points to the age duration of 66.3–65.1 Ma (late Maastrichtian-early Danian). The palaeomagnetic data also marks the presence of upper magnetic polarity transition (C29r/C29n) in the eastern part of the Malwa Subprovince, which indicates the occurrence of C30n-C29r-C29n magnetostratigraphic sequence for the Subprovince. The Malwa, eastern Mandla and Western Ghats Subprovinces can be palaeomagnetically correlated and are partly synchronous with each other.The Mothi Intertrappean deposition occurred in a low energy shallow water lacustrine setup with swampy to brackish depositional condition similar to shallow coastal lake type environment. The occurrence of such coastal type depositional environment at Sagar in the central part of India, points to the influence of temporary marine incursion and existence of marine pathway up to Central India, possibly through the western corridor of Narmada-Tapti rift zone during the late Maastrichtian-early Danian period. Moderate to intense chertification within the argillaceous limestone suggests post-depositional diagenetic modification and secondary silica generation due to interaction with silica enriched meteoric water diagenesis.

Published: August 2024

Background: Endometriosis is a chronic, gynecological disorder, and the disease’s pathogenesis is still debatable. Genes related to apoptosis have been revealed to be deregulated in endometriosis.
Objective: This study investigates the relationship between polymorphic variants of Bax -248G>A and Bcl-2 -938C>A promoter regions with endometriosis risk in an Iranian population.
Materials and Methods: In this case-control study, the polymorphisms of Bax -248G>A and Bcl-2 -938C>A promoter regions were analyzed in 127 Iranian cases and 125 controls who were referred to Ali-ibn-Abi Taleb Educational hospital, Zahedan, Iran between May 2022 and February 2023. The genotypic analysis was performed for all the subjects using the polymerase chain reaction-restriction fragment length polymorphism method.
Results: The frequencies of mutant allele A carriers and the A allele of Bax -248G>A polymorphism showed about 2-fold significant increase of endometriosis risk (p = 0.04; p = 0.01, respectively). The frequencies of the mutant genotype AA and A allele carriers of Bcl-2 -938C>A polymorphism were approximately 4 and 2.5-fold higher in endometriosis compared to the control women, which were highly significant (p > 0.001). Moreover, the allele A frequency of Bcl-2 -938C>A was associated with a 2-fold higher risk of endometriosis (p > 0.001). Furthermore, the combination effects of these 2 single nucleotide polymorphisms showed that women with Bax -248G>A GG and Bcl-2 -938C>A AA variant alleles were associated with about 5 times higher risk of endometriosis (p > 0.001). Notably, a significant difference was observed in mutant allele distribution between minimal/mild (stage I and II) and moderate/severe (stage III and IV) women with endometriosis disease.
Conclusion: The results of our study provide evidence that Bcl-2 -938C>A and Bax -248G>A single nucleotide polymorphisms might be associated with the risk of endometriosis.

Podzolic soil is marginal land for agriculture because low N availability and low lettuce plant growth production can be overcome by appropriate fertilization. This study aimed to determine the effect of fresh Azola application on nitrogen availability, number of leaves, and fresh weight of lettuce plants on Podzolic soil. This research employed a single factor of completely randomized design (CRD), in which the treatments were: A0= control, A1= fresh Azola 4 t ha-1, A2= fresh Azola 8 t ha-1, A3= fresh Azola 12 t ha-1, A4= fresh Azola 16 t ha-1. Soil chemical characteristics: soil pH, contents of total N, NH4+, NO3-, organic C, and cation exchangeable capacity were determined on the 21st after incubation, while plant height and plant fresh weight were observed at harvest. The research results showed that increasing the amount of fresh Azola applied to the soil resulted in a tendency to increase soil pH, total N-content, N-NH4+, N-NO3-, number of plant leaves, and fresh weight of lettuce plants.

The shovel-nosed lobster Thenus unimaculatus (Burton and Davie 2007) is one of India’s most important commercially exploited lobster species. The declining trends and collapse of the sand lobster fishery have been reported from the north-west coast of India. Several hypotheses have been proposed to explain this decline, but a lack of basic information on population demographics inhibits hypothesis testing. This study attempted morphometric stock structure analysis of T. unimaculatus along the Indian coast, using 673 specimens collected from five locations during 2017-2019. Data was subjected to allometric transformation to remove size effect and further subjected to multivariate analysis, including principal component analysis (PCA) followed by linear discriminant analysis (LDA) using R software. The first eight principal components (PCs) cumulatively explained 73.97% of the total variance. The misclassification rate (MR) of the LDA model performed to optimise separation among different sampling locations and coasts were 0.30 and 0.26 respectively, indicating clear overlap of the stocks. The results of this study revealed the presence of a single spawning stock of shovel-nosed lobster along the Indian coast, providing insights for adopting holistic management strategies to conserve this declining resource.

Abstract

The current selection of ligands for both proteins of interest (POI) and E3 ubiquitin ligase significantly restricts the scope of targeted protein degradation (TPD) technologies. This study introduces cell-penetrating peptide-induced chimera conjugates (cp-PCCs) targeting the DHHC3 enzyme involved in PD-L1 palmitoylation. This approach disrupts PD-L1's immunosuppressive function, enhancing anti-tumor immunity. We developed cp-PCCs to degrade DHHC3, directly linking DHHC3-mediated PD-L1 palmitoylation to PD-L1 stability on tumor cells. Our research utilized both in vitro assays and in vivo experiments in immune checkpoint blockade-resistant mouse models. We focused on a CRBN-based cp-PCC named PCC16, which demonstrated a DC50 of 102 nmol for DHHC3 degradation and significantly reduced PD-L1 levels. In resistant models, PCC16 not only robustly downregulated PD-L1 but also exhibited substantial anti-tumor activity in vivo without significant toxicity. This outperformed traditional inhibitors, showcasing the potential of cp-PCC technology to bypass current PROTAC limitations. Our findings suggest that cp-PCCs offer a promising method for targeting PD-L1 through DHHC3 inhibition and support their continued exploration as a versatile tool in cancer immunotherapy, especially for tumors resistant to standard treatments.

Authors: Wubishet Hailu 
Published: August 2024

Abstract

The aim of the study was to examine family involvement on schooling and impacts on the emotional well-being of preschoolers. This mixed design study discussed the emotional development conditions of preschoolers depending on two sample preschool centers. In examining the sample children’s emotion-related behavioral conditions, an EDI/AEDI tool was adapted and used. The tool gave score for each of sample items in a rating scale format (i.e. a three point scale) that ranged from 10 = highest or excellent; 5 = average or medium; and 0 = none/doesn’t exist the specific behavioral construct. Qualitative techniques of interviewing and document analysis of school-materials were also used. A t-test was used in analyzing the data which depended on teachers’ completion of sample preschoolers’ behavior development and text analysis was used in examining the qualitative data. Findings in the study evidenced that sample preschoolers from the private center received better emotional maturity scores than their counterparts in the public preschool. Preschoolers from the public school received higher scores on emotion-based problem behaviors. Furthermore, the study revealed that there was comparatively better family-school partnership and educational engagement by families from the private center than school-families interaction and involvement of families in the community preschool.
