Authors:   V.E. Zuev Institute of Atmospheric Optics SB RAS, 634055, Russia, Tomsk, Academician Zuev square, 1, Sherstobitov A.M.
Published: February 2025

The paper presents a new method for simulating physical layer of the BB84 quantum key distribution protocol and its implementation on a field programmable gate array (FPGA). The p5hoton polarization state is set using two clock signals generated in the internal FPGA generator. The process of measuring the polarization state of a photon is modeled using a detector based on an «XOR» logic gate. The results of testing the implementation of this method on FPGA are in a good agreement with the theory.

Problem-solving competency is crucial for social development, especially in complex environments. In mathematics education, problem-solving enhances logic, creativity, and analytical skills, contributing to societal progress. This article identified quantitative information about important publications, authors, resources, and research trends on mathematics problem-solving in high school education using the bibliometric analysis method. The input data is a set of 334 publications from the Scopus database published over four decades from 1983 to 2023. The results show that this field has obtained increasing interest, particularly in the last five years, with the USA and Indonesia being the countries with the most publications and Santos-Trigo and Putri Rii being the most influential authors. Three research trends include problem-solving in teaching mathematics in high schools, especially in teaching geometry and algebra; developing problem-solving and computational thinking skills through STEM education, engineering education, and educational computing for students; and using information technology to solve mathematics problems. These results provide teachers and researchers with helpful information about solving mathematical problems in general education, thereby contributing to shaping and proposing effective research and educational strategies, new teaching methods, training programs, and appropriate educational policies.
Ch'ae Yongsin’s Portrait of Zhu Xi (朱子): A Collaboration Between Confucian Scholars and an Artist to Honor Neo-Confucianism
Authors: Min Gilhong
Published: February 2025

Following the loss of Korea’s national sovereignty in 1910, many Confucian scholars sought to return to the essence of Confucianism, emphasizing self-cultivation and the acquisition of knowledge as a foundation for national restoration. In this context, Pak Manhwan (朴晩煥), who established Yŏngju Chŏngsa (瀛洲精舍) in Chŏngŭp, also constructed Yŏngyangsa (瀛陽祠) and commissioned Ch'ae Yongsin to paint portraits of twelve Confucian sages, including Zhu Xi (朱子). Ch'ae Yongsin not only created the requested portraits in Chŏngŭp but also traveled to other regions upon invitation to produce portraits of Zhu Xi. For instance, Confucian scholars in Chinju, Kyŏngsangnamdo, expressed their gratitude by composing farewell poems for Ch'ae after his visit. Among the portraits of Zhu Xi painted by Ch'ae, three are extant today. Through stylistic analysis, this study confirms Ch'ae’s authorship of the portraits housed at Yŏngyangsa in Chŏngŭp documented in records but lacking inscriptions and at Tot'ongsa (道統祠) in Chinju.The Confucian scholars of Chŏnbuk, including figures like Ki Uman (奇宇萬), Ch'oe Ikhyŏn (崔益鉉), Chŏn U (田愚), and Hwang Hyŏn (黃玹), shared a common commitment to national salvation. While their approaches varied—ranging from participating in anti-Japanese resistance to teaching Confucian principles or choosing martyrdom—their dedication to the nation was unified. Ch'ae Yongsin painted portraits of individuals across these groups. These works were commissioned by their descendants and disciples, but records in the Yuan (儒案) of Chinju’s Tot'ongsa and Sŏkkang silgi (石岡實記) suggest that Ch'ae indirectly or directly supported their endeavors. The life of Zhu Xi, who secluded himself at Wuyi Mountain to focus on writing and teaching, provided inspiration and guidance to Chŏnbuk’s Confucian scholars as they envisioned their future paths. Ch'ae Yongsin’s involvement significantly invigorated these efforts, serving as a pivotal figure in the cultural and intellectual activities of the time.
Choosing Well: A Scoping Review on Chronic Pain and Decision-making
Authors: Horta Marilyn , Wright Kylie , Lighthall Nichole Renee , Fillingim Roger B.
Published: February 2025

Chronic pain is one of the most prevalent and costly health conditions in the developed world. Previous work has demonstrated that chronic pain impacts cognition and behavior. However, the impact of chronic pain on daily decisions is less well-known. This scoping review identifies and synthesizes current literature on the impact of chronic pain on decision-making via changes in cognition and behavior. Broadly speaking, the effects of chronic pain on decision-making are evidenced by reduced overall performance compared to healthy controls in decision-making tasks, increased risk-taking and delay discounting, altered outcome sensitivity, and reduced cognitive flexibility and learning. Chronic pain effects on decision-making also vary by individual factors such as age, sex/gender, and affective and social factors. Guided by these findings, current limitations and future directions in the field are also discussed.
Synthetic Control Methods for Proportions
Authors: Bogatyrev Konstantin , Stoetzer Lukas
Published: February 2025

Synthetic control methods are widely used for causal inference in case studies and panel data settings, often applied to model counterfactuals for proportional outcomes. However, conventional synthetic control methods are designed for univariate outcomes, leading researchers to model counterfactuals for each proportion separately. We propose an extension to synthetic control methods to simultaneously handle multivariate outcomes in compositional data. Our approach establishes constant control comparisons by using the same weights for each proportion, improving comparability while adhering to treatment constraints. We illustrate the benefits of our method through a simulation and an empirical application to a recent study on climate policy effects in the 2019 Spanish general election. This advancement extends the validity and reliability of synthetic control estimates to common outcomes in political science.
Remembering without (representational) memory: A neuro-computational study on regaining categoricity and compositionality from minimal traces
Authors: Fayyaz Zahra , Righetti Francesca , Wiskott Laurenz , Werning Markus
Published: February 2025

This paper provides a proof of principle for the philosophical theory of Trace Minimalism (Werning, 2020), a novel account of episodic memory. It claims that remembering goes without the storage of representational content in memory. Remembering rather consists in the construction of a representation about a scenario, previously experienced, through the interaction of minimal traces with acquired statistical regularities. A minimal trace merely constitutes a causal link to the experience but possesses no trans-temporally transmitted representational (viz. categorical and compositional) content. Our proof of principle uses a neuro-computational model that is based on an autoencoder modeling the visual pathway and a transformer modeling the semantic information network. It assumes the hippocampus as the host of minimal traces. Our model demonstrates that minimal traces, which lack sufficient information for the reliable categorization and composition of content on their own, can be enhanced through interaction with semantic information. This process allows for the accurate construction of past scenarios, respecting regularities in the world, and supporting the reliability of episodic memory. Our findings suggest that episodic memory relies on sparse, fragmentary information rather than stored content, providing a robust proof of principle that remembering is possible without representational memory traces.

Over the last 20 years, personality development has become one of the most widely studied topics in personality science. However, evidence on normative and event-related personality development stems almost exclusively from Western countries, providing limited insight into the cross-cultural generalizability of personality trait changes. To address this limitation, we used data from the Africa Long Life Study to examine personality development in young adults from Kenya, Namibia, and South Africa over 1 to 2 years (N = 2,382). We found that the cross-cultural Big Two personality traits – Agency and Communion – were moderately rank-order stable over 1 year, with test-retest correlations of r = .38 to r = .55. In contrast to our expectations, Agency and Communion significantly decreased across the study period. Finally, using open-ended questions, we investigated the most important life changes of our participants and examined their associations with personality trait changes. We found that personality trait levels predicted the occurrence and perception of life events, while the occurrence and perception of life events, in turn, predicted personality trait changes. Overall, our findings were partly in line with but also partly diverging from findings on personality development from Western countries. This suggests that insights into personality development cannot automatically be generalized across cultural contexts but that a careful examination of which personality development phenomena are universal and which are culture-specific is warranted. Our study provides initial indications that environment-driven personality trait changes may be a mechanism of personality development that generalizes across cultural contexts.
Humans and neural networks show similar patterns of transfer and interference during continual learning
Authors: Holton Eleanor , Braun Lukas , Thompson Jessica Anne Farrell , Grohn Jan , Summerfield Christopher
Published: February 2025

Learning multiple tasks in succession is a challenge for artificial and biological agents alike. However, it is often claimed that artificial agents fail to learn new tasks without overwriting previous ones, while humans succeed. Here, using a canonical sequential rule-learning task in which learners acquire Task~A, then learn Task~B, and are finally re-tested on Task~A, we see conserved patterns of transfer and interference in humans and neural networks. When successive tasks are similar (compared to dissimilar), both types of learner benefit more from transferring prior knowledge to Task~B, but demonstrate greater interference when retested on Task~A. Examining the hidden representations in neural networks, we observe this interference arises because networks utilise their existing solutions to accelerate learning of similar tasks, whilst corrupting those solutions for their previous use. In humans, we also observe striking individual differences where some participants (`lumpers') show interference after sequentially learning two similar tasks, while others (`splitters') avoid interference. These two strategies are associated with opposite patterns of performance benefits: `lumpers' are better at learning shared structure across stimuli and generalising to new settings, while `splitters' are better at remembering unique features of the stimuli. By varying the training regime for neural networks (`rich' versus `lazy'), we can recreate these differences, pushing networks towards low-dimensional representations which capitalise on shared structure, or high-dimensional representations maximising discrimination between inputs. Overall, our findings reveal shared computational principles relating transfer and interference in both systems, governed by global factors like task similarity and individual differences in structuring knowledge.
The influence of syntactic priming on syntactic prediction in SOV languages
Authors: Husain Samar
Published: February 2025

Syntactic prediction and syntactic priming are known to be important determinants of processing in Subject-Object-Verb (SOV) languages. In this work we investigate how they interact during sentence processing of an SOV language Bengali. In a series of sentence completion studies, we find that both prediction and priming show consistent and robust effects. Interestingly, the strength of priming induced prediction is modulated by the structural similarity between the prime structure and the structure of the predicted construction in the target -- when this similarity is high, prediction strength increases, conversely, when the similarity is low, prediction strength decreases. We additionally find that priming induced prediction reaches a saturation point when prime structure is very complex (operationalized in terms of number of verbal arguments and thematic structure). These novel findings pose a challenge to the current theories of priming such as `residual activation theory' and the `implicit learning' model. The current work suggests that syntactic priming during comprehension could be modulated by language typology (SVO vs SOV). Broadly, we find that the parser in an SOV language predominantly prefers to posit syntactically simple structures and this tendency is not overridden by priming.
Generative AI Meets Open-Ended Survey Responses: Research Participant Use of AI and Homogenization
Authors: Zhang Simone , Xu Janet , Alvero AJ
Published: February 2025

The growing popularity of generative AI tools presents new challenges for data quality in online surveys and experiments. This study examines participants’ use of large language models to answer open-ended survey questions and describes empirical tendencies in human vs LLM-generated text responses. In an original survey of participants recruited from a popular online platform for sourcing social science research subjects, 34% reported using LLMs to help them answer open-ended survey questions. Simulations comparing human-written responses from three pre-ChatGPT studies with LLM-generated text reveal that LLM responses are more homogeneous and positive, particularly when they describe social groups in sensitive questions. These homogenization patterns may mask important underlying social variation in attitudes and beliefs among human subjects, raising concerns about data validity. Our findings shed light on the scope and potential consequences of participants’ LLM use in online research.
Living Qualitatively: Getting lost, to be found, only to be lost again
Authors: Lee Kai-Sean
Published: February 2025

This paper critiques the sterile, formulaic, and positivist tendencies in hospitality and tourism qualitative research, exposing several dangerous misconceptions including the false gold standard of data saturation, the mistreatment of subjectivity as a flaw, and the notion that qualitative research can be adequately taught in a single course alone. The author concludes with the idea of living qualitatively, a mode of inquiry that prizes becoming, resists sterile simplification, and centers epistemic humility—a process of getting lost, to be found, only to be lost again.
The Federal Parliament of Nepal: An Examination of Inclusive Representation, 2022
Authors: Mallik Sabita Kumari
Published: February 2025

Nepal is a country of varied and fair depiction of people from all backgrounds, makes the country multicultural, multilingual, multiethnic, multireligious, and diverse in terms of geography. Inequality in Nepal is still rife due to caste, ethnicity, religion, language, class, gender, and region, despite previous attempts at democratization and addressing issues of exclusion. The study is based on pragmatist philosophy. Multicultural and representative theories are appropriate for this study. Consequently, the study is ideally viewed as having significantly aided the federal parliament in the process of formulating policy. The representation percentage shows with the exception of Khas Arya, is significantly less than the quota assigned to these groups, despite the fact that the PR system has yielded positive results. Legislation pertaining to inclusive representation by the relevant authority needs to be changed in order to guarantee that the inclusive standards and values are fairly promoted and upheld.

In the article the results of work on the assessment of the genetic diversity of Kazakhstani coenopopulations of a rare plant species Adonis wolgensis Stev. are presented. Samples for research were collected in five cenopopulations of Kostanay, Akmola, Pavlodar regions of the Republic of Kazakhstan. The genome of A. wolgensisis not sequenced, therefore, a PCR method was used to detect DNA polymorphism in coenopopulations of this species for the simultaneous detection of multilocus DNA polymorphism that did not require initial knowledge of the nucleotide sequences of the entire genome or its parts. One of the most common methods for detecting genetic polymorphism in plants is ISSR-labeling (Inter Simple Sequence Repeats, or intermicro-satellite analysis). For PCR we used five primers with a length of 17–22 nucleotides. Separate amplification was carried out with each of them. Such primers allowed to amplify DNA fragments that are between two closely spaced microsatellite sequences. As a result, a large number of fragments, represented on the electrophoregram by discrete bands (ISSR-fingerprinting), was amplified. In total, more than 450 analyzes were performed (including repeated studies). As a result, multiple genomic marking of five coenopopulations of A. wolgensisin northern Kazakhstan was carried out, the main indicators of genetic diversity, the structure and differentiation of gene pools of populations, the studied plant species were determined.

Composite stratigraphic section across the mid-Miocene climatic optimum and transition in the Tesuque Formation, Espanola Basin, north-central New Mexico
Authors: Williamson Garrett R. , Sweet Dustin E.
Published: February 2025

The Española Basin is a west-tilted half-graben formed from extensional stresses related to the formation of the Rio Grande Rift. Intrabasinal normal faulting created a series of sub-grabens within the Española Basin. Importantly, this stratigraphic record provides one of North America’s best Miocene vertebrate fossil records. Yet, the composite stratigraphic section necessary to place those fossil occurrences into a biostratigraphic framework is unavailable largely because the tectonic framework creates a complex mosaic of facies, making the correlation of individual stratigraphic sections difficult. However, numerous widespread and distinguishable ash beds occur within the strata that help correlation across complex structural and facies relationships. This paper provides a composite stratigraphic section targeting fossil-rich regions within the Bureau of Land Management’s Sombrillo Area of Critical Environmental Concern, documenting periods of progradation and retrogradation of the alluvial fan facies.

Integrating previously published climatic and tectonic data with new paleontological data into a stratigraphic and lithofacies framework bears on the environmental evolution during and after the middle Miocene Climatic Transition (MCT). From approximately 17 Ma to 14 Ma, the Española Basin experienced a period of warmer and wetter conditions during the middle Miocene Climatic Optimum (MCO) reflected by alluvial fan facies. Towards the end of the MCO, alluvial fan facies began to retrograde. We infer these results to indicate that climate provides more influence on sedimentation because alluvial fan retrogradation corresponded with less vegetation and, thus, less sediment stability associated with cooler conditions, as demonstrated by previous stable isotopic studies. As the regional climate cooled and dried, the Española Basin remained wet, although cooler conditions forced the local extinction of palm trees. This is also supported by the increase in antilocaprid abundance and the appearance of gomphotheres attracted to the riparian zones during this time of regional aridity.
Adnexal Torsion During Controlled Ovarian Stimulation: A Case Report
Authors: Thiangphak Ekasak , Matemanosak Phawat , Wirotkarun Suwadee
Published: February 2025

A 34-year-old nulliparous woman with polycystic ovarian syndrome presented with mild discomfort in her right abdomen three hours before her scheduled retrieval. She underwent a transvaginal oocyte retrieval. Oocytes were obtained from the ovary; however, the right ovary was inaccessible as it was located above the uterine fundus. Consequently, the decision was made to abandon retrieval from the right ovary. After the procedure, the pain continued, and a physical examination indicated signs of peritonitis. Right ovarian torsion was suspected, leading to laparoscopic detorsion with transabdominal oocyte retrieval from the untwisted ovary. One mature oocyte was retrieved from the torsion-affected ovary, resulting in an embryonic arrest at the morula stage. Additionally, we reviewed the literature on the outcomes of in vitro fertilization cycles in women with ovarian torsion before oocyte retrieval.
Evaluation of the influence of multiphase fluid parameters on the natural frequencies of above-ground field pipelines
Authors: Cherentsov D. A. , Pirogov S. P.
Published: February 2025

The most common method for constructing field pipelines on permafrost  is above-ground installation on supports. The span between these supports must be determined  to avoid resonance frequencies caused by vortex excitation from wind loads. While many studies have aimed to determine natural frequencies, the impact of multiphase fluids has not been thoroughly explored.

The purpose of the study is to determine how the parameters of multiphase fluids influence the natural frequencies of oscillations in above-ground field pipelines.

As a leading method, we use solution of the differential equation of the mathematical model of transverse deformations of a rod under the influence of longitudinal forces.

The study found that changes in natural frequencies resulting from changes in the parameters of the transported multiphase fluid remain within a manageable range. This assessment considers the fluid solely as an additional mass, both under no pressure conditions and at the maximum allowable pressure for which the pipeline was designed. Additionally, changes in water cut and gas factor affect the density of the overall flow, which, in turn, alters the mass of the transported fluid. This change in mass has a greater influence on natural frequencies than internal pressure.

It is demonstrated that, when determining the placement of supports for above-ground field pipelines, it is essential to use the natural frequencies that account for the additional mass, considering both no-pressure and maximum-allowable-pressure conditions.

TELECOMMUNICATION PROPERTIES OF A SEGMENTED CABLE LINE IN THE NONLINEAR RESPONSE METHOD
Authors:   Khmelnytskyi National University, PYVOVAR OLEG
Published: February 2025

The sensor cable line, along with it’s main function, can be used as a data link between the detectors and the system control center. In terms of simplicity and cost efficiency, it is advisable to use the nonlinear response method, which implies the use of nonlinear devices as damage control elements. A reasonable choice of the geometrical parameters of the line, the construction of the line segments, the level of misalignment of the segments, the model of consideration of the noise properties of the line was made in order to determine the bandwidth of the telecommunication channel. An analytical model was developed to determine the bandwidth of a segmented cable line with nonlinear elements based on the established limitations of the nonlinear method. The bandwidth estimation of the segmented touch line is estimated while varying the parameters of the cables used. The most optimal parameters for real application were highlighted. A noise scheme model is proposed to estimate the total noise level in a segmented cable line with Zener diodes. For typical Zener diodes and optimal transmission line parameters, the upper limits for the total noise level were set. Based on the nature of the nonlinear response method and the determined frequency and noise parameters for the digital telecommunication sensor channel, the lower bandwidth limit was estimated.

The main goal of the paper is to consider the modern terminology that regards to the technical regulation and standardization. It is established that technical law system that maintain regulation in the field of quality control is one of the most important in any country’s development. During last few decades Ukraine is slowly moves to maintain control over its technical regulation system in the same way as it is preferable in the most developed countries of the world. In order to collect the input data for the current work authors considered the laws of Ukraine and recent scientific works in the area of standardization as well as standard and normative documents themselves. The definitions of the terms were gathered by authors of the paper. As a result the classification of terms and definitions those are used in the mentioned area was developed. They suggested to split all the documents into those that contain mandatory requirements and those that might by applied on a voluntary basis. The term “regulatory document” is proposed to be used as a generic. As due to the regulatory documents, which are mandatory, authors suggest to use the term “regulatory act”. On the other hand, in regard of the regulatory documents, which are not mandatory, but might be used on a voluntary basis, the term “standardization document” is preferable.

The hallmark of any change in society is the saturation of its various weapons. It occurs both in the sphere of its legal and illicit trafficking. This fact could not but be reflected in the criminal situation in the country. The main danger lies in the quality characteristics of criminal offences committed. In criminal proceedings, forensic examination of cold weapons is important because, based on the conclusion of a judicial expert, the qualification of the suspect’s actions is carried out and the presence of the crime in these actions is established. Belonging to a cold weapon is determined by the presence of the subject (device) in the test, the set of such common forensic features: the purpose for defeating the goal; fitness for repeated damage to the target. For short-blade objects, it is important to establish the suitability of the object for defeating the target, which is determined by the availability of technical security as separate elements, as well as the design as a whole, as well as the sufficiency of its affecting properties. Tests are conducted in accordance with the methodology of the three schemes. The existing designs of devices for static testing of short-blade cold weapons are analyzed and their drawbacks are revealed. To perform research on the main measurement schemes, a universal overlapping design of a special device for the static testing of short-blade cold weapons has been proposed. Features of the main units of the device are considered. A device for static testing of short-blade weapons allows to increase the convenience of measuring the deflection and residual deformation of short-blade weapons and to increase the accuracy of measurement of characteristics in static experimental studies to determine the suitability of short-blade objects to hit the target.

ITERATION-GEOMETRIC METHOD FOR PERMANENT PERCIPTUAL HASHING OF IMAGE
Authors: DZHULII V , KLOTS Y , MULIAR I , CHESHUN V ,   Khmelnytskyi National University
Published: February 2025

The purpose of the work is to create a unified structure for perceptual media hashing. The main goal is to consider fundamental ideas in perceptual hashing of an image. To increase the efficiency of information processing in automated control systems and image processing, there is a need to develop methods for reliable hashing and identification of graphic images. Improving the efficiency will significantly expand the scope of application software in control systems and information processing. This approach will be useful for identifying images in databases, in which it is possible to make various changes to the image, such as compression and format changes, general signal processing algorithms, scanning, or creating watermarks. Developed basic clustering, allows clusters not to bear any losses. Based on the study, two main goals of perceptual image hashing have been identified: resistance to unintentional or perceptually minor image modifications – perceptual hash persistence; the ability to withstand deliberate attacks (caused by a malicious opponent) is a hash of security. The hash of the security properties is closely related to the randomization scheme that is used when creating the hash algorithm. Another extremely important question that needs to be answered is what hash length is required to successfully obtain the desired level of stability. The theoretical analysis of randomized media hashing algorithms and the quantitative relation of randomized parameters with hash security has not yet been addressed in the literature. In the article the approaches for calculation of statistical values of graphic representations which will grasp the main features of the image are considered and remain as a matter of fact not changed through comprehensible transformations. The offered methods are flexible and can be used for the decision of other problems.

Kimak, Tanah Bawah, and Silip are three villages in Bangka Regency, Bangka Belitung Islands Province, Indonesia, where animals are still used for traditional medicine. This study aimed to collect, analyze, and evaluate data on the use of animals in traditional medicine by the communities of Kimak, Tanah Bawah, and Silip. The research was conducted over three months, from March to May 2024. Data collection involved surveys and informant selection using the snowball sampling method. Fifteen selected informants were interviewed based on a prepared questionnaire. Data analysis was carried out qualitatively (using descriptive statistics) and quantitatively (calculating the Relative Frequency of Citation (RFC) and Informant Consensus Factor (ICF)). The results showed a positive correlation between informants’ age and their knowledge of animal-based traditional medicine, with informants over 45 years old possessing broader knowledge due to their longer life experiences. Dependence on traditional medicine was influenced by limited access to modern healthcare services and the cultural and spiritual significance of these practices. A total of 14 animal species from five classes were used, with Mammalia being the most dominant class (35.7%). Malayopython reticulatus had the highest RFC value (0.667), while species with the lowest RFC values (0.067) included Nisaetus cirrhatus, Galeopterus variegatus, Trachypithecus cristatus, and Nesolagus netscheri. The most commonly used body part was meat. ICF analysis indicated that disease categories such as skin ailments, internal injuries, nerve disorders, ulcers, hemorrhoids, and mental illnesses had the highest levels of informant consensus. Several used species are classified as threatened, highlighting the need for stronger conservation efforts through collaboration between the government, conservation organizations, and local communities. Balancing conservation with traditional medicine practices is essential to preserving cultural heritage while supporting ecological sustainability.

The global shift towards renewable energy sources has led to a significant increase in bioethanol production, particularly from sugar mills. Despite being an environmentally friendly alternative to fossil fuels, bioethanol production produces large amounts of waste containing dangerous contaminants such as nitrate ions (NO₃⁻). These contaminants pose severe environmental and health risks, including water pollution and eutrophication. This study explores the use of ammonium polymer as an adsorbent and the influence of pH in the adsorption process as a promising technique for removing nitrate ions from bioethanol waste. Based on the analysis that has been carried out, the optimal pH for adsorption of nitrate ions is around 9, where the removal efficiency (%RE) reaches 98.43% and the adsorption capacity (Qe) is 24.86 mg/g. These experiments show that the Freundlich model, with a heterogeneity factor (n) of 1.0947 and a Freundlich constant (KF) of 1.92 x 10³ units, provides the best fit to the adsorption data, indicating a heterogeneous adsorption process with a strong affinity for nitrate ions.

Published: February 2025

Pembayaran Pajak Bumi dan Bangunan (PBB) sebagai pajak yang disetorkan setiap penduduk khususnya di wilayah Kabupaten/ Pedesaan. Pengetahuan Masyarakat yang lebih berkembang rata-rata masih didominasi oleh penduduk kota dibandingkan penduduk desa. Masih terbatasnya pengetahuan penduduk mengenai pajak, khususnya di Desa menjadi pokok utama pemasalahan penelitian. Lokasi adalah Desa Sihene’asi. Tujuan penelitian (1) untuk menganalisis kesadaran, kepatuhan dan pembayaran pajak di lingkup Desa Sihene’asi, (2) untuk menganalisis pengetahuan masyarakat mengenai pengetahuan masyarakat tentang pengetahuan PBB. Variabel dependen yaitu pembayaran, kesadaran dan kepatuhan. Metode penelitian adalah data kuisioner berjumlah 91 orang. Hasilnya bahwa Kesadaran (WP) dan Kepatuhan (WP) berpengaruh terhadap pembayaran PBB di Desa Sihene’asi Kecamatan Lahewa, sehingga masyarakat sudah cukup mengetahui dalam pembayaran pajak, penerapan untuk pembayaran pajak sudah dijalankan oleh masyarakat, hal ini berarti bukan menjadi hambatan dalam pengembangan untuk kemajuan wilayah setempat.

Innovation in Accounting Information Systems (AIS) is able to encourage companies to improve their performance in terms of financial management. Accounting Information Systems (AIS) in the modern financial sector are used to manage company financial transaction data. This research examines the keys to success in utilizing AIS at PT PQR. On the app Enterprise Resource Planning (ERP), AIS is part of managing company financial data. PT PQR as a company operating in the telecommunications sector that manages many transactions is very suitable to develop AIS. This research uses a qualitative approach through literature study. Data was obtained through collecting, analyzing and interpreting the keys to successful implementation of AIS at PT PQR. The research results show that there are 7 (seven) main factors that most influence the success of AIS. The 7 (seven) factors include: organizational culture, information technology, application of accounting information, manager participation, manager accounting knowledge, manager information technology knowledge, and consultation with experts.

This paper proposes a hybrid control architecture dedicated to the navigation of autonomous mobile robots in presence of obstacles. The proposed control structure is flexible, adaptive and takes into account the different possible interactions between the multitude of controllers composing the architecture of control. This is enabled by the use of stable elementary controllers and to specific mechanisms of coordination and adaptation which guaranties the stability of the overall architecture.
Prototype-based Domain Description
Authors: Angiulli Fabrizio
Published: February 2025

In this work a novel one-class classifier, namely the Prototype-based Domain Description rule (PDD), is presented. The PDD classifier is equivalent to the NNDD rule under the infinity Minkowski metric for a suitable choice of the prototype set. The concept of PDD consistent subset is introduced and it is shown that computing a minimum size PDD consistent subset is in general not approximable within any constant factor. A logarithmic approximation factor algorithm, called the CPDD algorithm, for computing a minimum size PDD consistent subset is then introduced. The CPDD algorithm has some parameters which allow to tune the trade off between accuracy and size of the model. Experimental results show that the CPDD rule sensibly improves over the CNNDD classifier in terms of size of the subset, while guaranteeing a comparable classification quality.
Nonnegative Decompositions with Resampling for Improving Gene Expression Data Biclustering Stability
Authors: Badea Liviu  , Ţilivea Doina
Published: February 2025

The small sample sizes and high dimensionality of gene expression datasets pose significant problems for unsupervised subgroup discovery. While the stability of unidimensional clustering algorithms has been previously addressed, generalizing existing approaches to biclustering has proved extremely difficult. Despite these difficulties, developing a stable biclustering algorithm is essential for analyzing gene expression data, where genes tend to be co-expressed only for subsets of samples, in certain specific biological contexts, so that both gene and sample dimensions have to be taken into account simultaneously.
A generic framework for comparing semantic similarities on a subsumption hierarchy
Authors: Blanchard Emmanuel  , Harzallah Mounira  , Kuntz Pascale
Published: February 2025

Defining a suitable semantic similarity between concept pairs of a subsumption hierarchy is becoming a generic problem for many applications in knowledge engineering exploiting ontologies. In this paper, we define a generic framework which can guide the proposition of new measures by making explicit the information on the ontology which has not been integrated into existing definitions yet. Moreover, this framework allows us to rewrite numerous measures, originally proposed in various contexts, which are in fact closely related to each other. From this observation, we show some metrical and ordinal properties. Experimental comparisons on Word-Net and on collections of human judgments complete the theoretical results and confirm the relevance of our propositions.
