Privacy Preserving and Secure Iris-Based Biometric Authentication for Computer Networks
Authors: Strzelczyk Przemysław
Published: April 2024

The iris biometrics is considered one of the most accurate and robust methods of the identity verification. The unique iris features of an individual can be presented in a compact binary form which can be easily compared with the reference template to confirm identity. However in contrast to passwords and PINs biometric authentication factors cannot be revoked and changed as they are inherently connected to our characteristics. Once the biometric information is compromised or disclosed it became useless for the purpose of authentication. Therefore there is a need to perform iris features matching without revealing the features itself and the reference template. We propose an extension of the standard irisbased verification protocol which introduces a features and template locking mechanism, which guarantee that no sensitive information is exposed. Presented solutions can be easily integrated into authentication mechanisms used in modern computer networks.
ACCOUNTING INFORMATION DISCLOSURE: HOW FAR IS SO FAR
Authors: Akande Folorunso Ilesanmi , Okwu Titus Andy , Egwakhe Ashiemamho Johnson , Umukoro Jones Emakpor
Published: April 2024

Purpose: Accounting information asymmetry increases moral hazard, agency costs, shareholders’ discontent, and further aggravates the discomfort of minority shareholders. As such, how far is so far when connecting information disclosure with firm characteristics has remained a debate. This study thus investigated the nexus between firm characteristics and accounting information disclosure with emphasis on the banking sub-sector in Nigeria.
 
Theoretical Framework: Accounting information disclosure is not hidden from theoretical discussions within the corridors of opportunistic behaviors, agency-theory and information asymmetry or information failure theory
 
Design/Methodology/Approach: Annual reports of eleven top banks in Nigeria were analyzed covering a period of 5 years from 2010 to 2014 using the firm characteristics – size, profitability, age, and international presence. A disclosure checklist consisting 137 voluntary items was developed and multiple regression analysis performed.
 
Findings: The results revealed a positive significant relationship between accounting information disclosure with age, international exposure, and a negative significant relationship was observed for profitability and size. Generally, the level of disclosure in the banking sector was found to be high at 62%.
 
Research, Practical & Social Implications: This study recommends accounting information democratization and sharing to build and restore confidence in banks’ activities and public perception.
 
Originality/Value: The investigation on how far is so far in accounting information disclosure should be perceived from the eye of the stakeholders investments. Be that as it may, it is only fair and ethically moral for persons/groups that have invested in a business and or in a bank to regularly have access to concrete and verifiable mandatory and voluntary information disclosure on the financial position of their hard-earn funds to make reasonable decisions.
Swallowing Difficulties, Oral Symptoms, and Nutrition in Long-Term Care Elderly Residents – A Secondary Publication
Authors: Lindroos Eeva
Published: April 2024

Oral health is often impaired in people living in residential care. In older people, poor oral health is associated with functional deficits, multiple sclerosis, and memory disorders. Keeping one’s teeth healthy throughout life would promote both oral health and general health. Biting and swallowing problems in older people are also linked to oral health, limiting eating activities and requiring diet changes to softer foods that are easy to chew and swallow. This may limit dietary diversity and adequate nutrient intake. Although eating-related chewing and swallowing problems are common in institutionalized residents, they are often addressed too late, when the resident is already malnourished. Nutrition in nursing and retirement homes has been the subject of various studies since the 2000s. However, studies on swallowing and chewing difficulties are scarce and their link to adequate nutrient intake has received lesser attention [6,7].

Методом термического испарения получены пленочные гетероструктуры составов Ag/Au/Ti, Ag/Au/CFR-PEEK при последовательном осаждении подслоев металлического золота и наноструктур серебра на современные биоматериалы (сплав Ti-6Al-4V, полиэфирэфиркетон CFR-PEEK). Содержание серебра варьировали в интервале 2.1-20.8 мкг/см2 путем изменения исходной навески металла (1.2-5 мг) и количества последовательных нанесений (1-3). По данным СЭМ, на поверхности золотых подслоев формируются нанопленки Ag толщиной до 10-15 нм. По данным РФЭС на поверхности биоматериалов золото присутствует в металлическом состоянии, тогда как для серебра наряду с металлом регистрируется таже наличие оксидной фазы Ag2О. Методом ИСП-АЭС исследована динамика (2-48 ч) растворения серебра с поверхности Ag/Au. Обнаружено, что, независимо от концентрации серебра, образцы демонстрируют умеренную динамику выделения ионов металла, наряду с серебром в растворе также регистрируется небольшое количество золота. Показано отсутствие цитотоксичности синтезированных пленочных гетероструктур in vitro (клетки L-929, жизнеспособность >95-98%). Гетероструктуры полностью подавляют рост колоний грамотрицательных (P. аeruginosa) и грамположительных (S. аureus) бактерий через 6 и 24 часа воздействия, соответственно.
Some New Results on BE-Algebras
Authors: Romano Daniel Abraham
Published: April 2024

BE-algebra was introduced in 2007 by H. S. Kim and Y. H. Kim. Then this class of logical algebras was the focus of many researchers. In this paper, the concept of atoms in BE-algebras is introduced and analyzed, and, in addition, it is directly connected to two-membered BE-filters. A criterion was found for determining the existence of atoms in these algebras. In addition to the previous one, the paper designs two types of BE-algebra extensions by adding one element so that the additional element is an atom in it. In addition to the previous one, two new types of filters in BE-algebras are designed.

El documento propone el diseño, implementación, programación y uso de una Nariz Electrónica (E-NOSE) para la identificación de patrones en los gases respiratorios exhalados en personas con problemas respiratorios y personas sanas, con el objetivo de identificar de forma rápida la patología conocida como enfermedad pulmonar obstructiva crónica (EPOC).  La Nariz Electrónica (E-NOSE) está conformada por un arreglo de sensores MQ de bajo costo, un microcontrolador Arduino, algoritmos de Redes Neuronales y una cámara de concentración de gases. La adquisición de datos se realizó en el hospital general de Ecatepec “Dr. José María Rodríguez” con el consentimiento del comité de Bioética de dicho hospital, pacientes sanos y pacientes diagnosticados con EPOC. Almacenamos los datos para su posterior procesamiento, lo que nos permitió entrenar, validar y probar una red neuronal para poder clasificar a pacientes sanos de enfermos de EPOC. El modelo se entrenó con datos sin preprocesamiento. Los resultados obtenidos nos dieron una matriz de confusión del 92% lo cual indica la posible viabilidad del prototipo. El prototipo deberá mejorar sustantivamente la cámara de concentración de gases empleando la manufactura aditiva y buscando mejorar la calidad de los datos mediante un preprocesamiento.

History and Humor
Authors: Hinz Amy
Published: April 2024

Arguably, Monty Python’s The Life of Brian is one of the most controversial interpretations of Christ’s story, due to the Pythons’ shrewd, satirical sense of humor and the film’s mockery of the historical public’s admiration and obsession with messianic figures. This paper takes a similar stance to scholars who argue, however, that the film is not blasphemous—it does not mock Christ himself. The argument hinges on the distinction between Christ and Brian. In separating Christ and Brian into two figures, the film operates on another level, allowing viewers to experience the rise of a messianic figure through Brian as well as introducing them to the historical context. Therefore, though ostensibly not about Christ, The Life of Brian provides insight into the historical time period of Christ and can be beneficial for those interested in furthering their understanding of Christ’s story.

Published: April 2024

Este trabalho tem como objetivo principal fomentar a importância de diálogo jurídico sobre os avanços tecnológicos vivenciados atualmente. A internet, desde a sua primeira geração, Web 1.0, transforma a forma como a sociedade se relaciona e troca informações, ao ponto que, atualmente, vive-se o paradigma da sociedade do Big Data. Percebe-se que a evolução da internet contribuí muito para o avanço tecnológico da sociedade, mas ao mesmo tempo direitos e garantias fundamentais estão cada vez mais vulnerabilizados, em razão deste paradigma existente baseado nas características da Web 2.0. Assim, a partir de uma análise sobre a evolução da internet, busca-se avaliar os efeitos jurídicos da Web 2.0 e suas implicações na preservação de fundamentos que tutelam o direito constitucional à proteção de dados, tal como a autodeterminação informativa. Através dessa análise, é exposta tecnologias que buscam inovar a Web 2.0 e que estão balizadas em dispositivos jurídicos existentes atualmente, visando um paradigma que objetiva a criação de ecossistemas digitais descentralizados, seguros e transparentes, conhecido como Web3. No Brasil, para que isso seja possível, sob o ponto de vista jurídico, é necessário acompanhamento constante da Autoridade Nacional de Proteção de Dados sobre a temática de inovação tecnológica, com o intuito de regular direitos já existentes, que possam contribuir para um ambiente mais seguro e democrático e possibilitar o estudo de tecnologias já em desenvolvimento em outros países que operam sob o prisma da Web3 e que podem ser a contribuição chave para a democratização segura da internet.

A Theoretical Study of Lithium-intercalated Pristine and Doped Carbon Nanocones
Authors: Ahmadi Peyghan Ali , Noei Maziar
Published: April 2024

The energetic, geometric, and electronic structure of Li-adsorbed pristine, B- and N-doped carbon nanocones (B- and N-CNCs) were investigated by means of density functional theory. It was found that Li atom is strongly adsorbed above the center of pentagonal ring of the pristine CNC with the adsorption energy of −1.08 eV (at B3LYP/6-31G(d)) along with the charge transfer from Li to the CNC. After this process, the semiconductive CNC is transformed to an n-type one, so that its HOMO-LUMO energy gap (Eg) is reduced from 2.51 to 0.71 eV (at B3LYP/6-31G(d)). Doping semiconductive CNC with B or N atom also creates a p- or n-type semiconductive material, resulting in an increased conductance. B-doping improves the Li adsorption on the CNC, while N-doping hinders this process. It seems that Li atom acts as an electron-donor agent with n-type effect, and therefore, its adsorption on the B-CNC somewhat compensates the p-type effect of B-doping. On the contrary, the adsorption process on the N-CNC moderately promotes the n-type effect of N-doping, leading to more reduction in the Eg value.
Effect of Multiwalled Carbon Nanotubes on the Properties of PMMA/PEO Blends
Authors: Saeed Khalid , Khan Nasib
Published: April 2024

Poly (methyl methacrylate) (PMMA)/Poly ethylene oxide (PEO) (15 wt.% PMMA/85 wt.% PEO (PMMA/PEO-A) and 30 wt.% PMMA/70 wt.% PEO (PMMA/PEO-B)) blends, and functionalized multiwalled carbon nanotubes (F-MWNTs) filled PMMA/PEO-A and PMMA/PEO-B composites were prepared via solution casting technique. The morphological study showed the formation of cracks in F-MWNTs/PMMA/PEO blend. The mechanical properties of PMMA/PEO blend were decreased by incorporation of F-MWNTs, which might be due to less compatibility between F-MWNTs and PMMA/PEO blends. Neat PEO upon crystallization showed distinct sized spherulites, which decreased by the incorporation of F-MWNTs (nucleation effect of FMWNTs). The X-ray diffraction (XRD) analyses revealed that the intensity of peaks decreased by incorporation of nanotubes, which means that the PEO crystallinity was suppressed in the presence of F-MWNTs. The thermal stabilities of PMMA/PEO blend were improved by incorporation of F-MWNTs.

Social sensing with big data: Detecting hate speech in social media
Authors: Umar Ibrahim  , Usman Lawal Gulma  , Ishaq Abdullahi Lawal
Published: April 2024

The internet's accessibility and social media platforms, like Facebook and Twitter, have accelerated the spread of hate speech and fake news, both of which can be detrimental to society's overall well-being. Identifying and tracking hate speech is becoming increasingly difficult for the public, private citizens, legislators, and academics. Despite efforts to leverage automatic detection and monitoring techniques, their performances are still far from satisfactory. This study employs Natural Language Processing (NLP) and Machine Learning (ML) approaches to detect hate speech for decision-making. The result showed that the Support Vector Machine (SVM) algorithm has the best performance with an accuracy of 0.86 compared to the Random Forest with 0.8 accuracy. The manual evaluation of the performance of our algorithm yielded an inter-annotator agreement Cronbach’s alpha (α = .775).
On the formation of Oxydimorphine (pseudomorphine, 2.2’-bimorphine)
Authors: Francisco Sánchez-Viesca  , Reina Gómez Gómez
Published: April 2024

In Beckurt’s test for alkaloids the substance for assay, generally a salt, is treated with a 0.1 N solution of potassium permanganate. In his study he used the hydrochloride of the alkaloid. In this communication the reactivity of both reagent and substrate have been checked and commented. The electron donor property of the phenol in morphine is enhanced by reaction with a weak base such as water. A phenoxy ion and a hydronium ion are formed. Resonance produces a carbanion at C-2 which transfers an electron to permanganate ion. This reduction to manganate is concomitant to oxidation of the organic molecule. The free radical thus formed is stabilized by electron coupling and 2,2’-bimorphine is obtained.
Analysis of thermo-acoustic parameters in view to obtain the interaction between acetamide in some salt solutions at different temperature

Published: April 2024

The ultrasonic velocity and density have been calculated for acetamide in the solution NaCl and KCl at different temperatures (viz. 283, 288,293,298K) for various concentrations from 0.02-0.2mol/kg thermodynamic and sound parameters such as adiabatic compressibility, acoustic impedance, relative association, internal pressure, available volume, specific heat ration, relaxation strength, isothermal compressibility, molecular radius, surface tension, enthalpy, Rao’s constant, Wada’s constant, free length, have been gained from research examination for the (Acetamide +H2O/NaCl/KCl). To investigate exactly the type of molecular interactions that exist with NaCl and KCl with acetamide. Among them, KCl with Acetamide interacts most strongly, at a higher concentration as compared to NaCl and H2O solvent. They give stronger solute-solvent interaction with higher mass fractions at higher temperatures.

Authors: Nasooh Ismail
Published: April 2024

Weather forecasting, particularly in short timeframes has been a longstanding challenge in meteorology, addressed in part by nowcasting methods. Leveraging radar data and innovative methodologies, nowcasting tools have evolved significantly, with open-source python platforms like Pysteps making is accessible to researchers to try advanced techniques. This review focus on Pysteps, a modular and user-friendly framework, offering optical flow based deterministic nowcasts and Short-Term Ensemble Prediction System (STEPS) ensemble nowcasts. Recent studies highlights its efficacy, including blending with Numerical Weather Prediction (NWP) models for improved performance beyond the nowcasting timeframe. Pysteps emerges as a versatile solution, facilitating both research innovation and operational forecasting needs, with wide range of input data and modularity.

Aims: Evaluate the contribution of hysterosalpingography in the exploration of female infertility in order to improve its management. Materials and methods: This was a retrospective study from 07/24/2017 to 11/30/2020, and prospective from 12/15/2020 to 03/10/2021 at the Radiology department of the General Reference Hospital of Niamey collecting 223 patients referred for hysterosalpingography as part of the infertility assessment. Results: the average age was estimated at 28.9 ± 7 years with extremes of 15 and 47 years. The age group of 20 to 30 was the most represented with 53.8%. Patients were referred for primary and secondary infertility in 44.8% and 48% respectively. HSG was normal in 53.8% and pathological in 46.2%. Tubal pathologies were found in 44.7% represented by tubal obstruction in 100% of cases; a hydrosalpinx in 21.4%; and one case of tubal endometriosis (1.4%). Uterine pathologies were revealed in 32% of cases, dominated by fibromyomas and uterine polyps in 47.4% and 26.3% respectively. Conclusion: In Africa, a childless couple is often subject to various pressures from the family as well as society. The birth of a child in a home is a source of joy, and contributes more or less to maintaining a certain stability and harmony in the household.

To determine the microbiological profile of catheter-related infections at the Mohammed VI University Hospital Center in Oujda, we conducted a prospective study from January 31, 2023, to October 30, 2023. All non-tunneled hemodialysis catheters received in the laboratory for microbiological examination were included. Out of a total of 157 samples received, 53 were positive, with a rate of 33.75%. Gram-positive cocci accounted for 73.43% of the identified strains, while Gram-negative bacilli constituted 25% of the isolated bacteria. Staphylococcus aureus was the predominant species with a frequency of 42.18%. Furthermore, 59.25% of Staphylococcus aureus strains were methicillin-resistant. Enterobacteriaceae showed resistance to ceftazidime in 36.36% of cases; 27.27% of Enterobacterales exhibited an extended-spectrum beta-lactamase (ESBL) phenotype. All Acinetobacter baumannii strains were resistant to imipenem. It is necessary to characterize the bacterial ecology and determine antibiotic sensitivities to better guide therapeutic management.

Background & Aims: Precise positioning of oral Endotracheal tube (ETT) anytime is difficult however if attained will ease complications of its misplacement. The accuracy in positioning oral cuffed ETTs to the correct depth in Indian adults following conventional guidelines was sought for. Methods: This study was conducted upon 240 adults ageing 20 to 60 years of both sex, who required endotracheal intubation at operation rooms or already intubated due to any reason admitted in CCU of BSMC&H, Bankura, West Bengal, excluding patients with hemodynamic instability and upper airway deformities. Oral ETT intubation was performed and ETT fixed at incisors following conventional guidelines. ETT tip to Carina distance was measured with fiberoptic bronchoscope thereafter. The power of study was kept at 0.95. Obtained data were evaluated with descriptive and inferential statistical tests by Microsoft Excel 2016. Results & Conclusions: Only 60% (n=144) of ETTs were found to be accurately positioned. In the rest 40% (n=96) of misplaced ETTs, the majority (91%, n=87) were placed too deep. Predetermined fixing the ETTs at 21 cm and 23cm mark in females and males respectively leads to deep placement in 36% of them. Hence, we can declare that securing ETT at midline according to the conventional guidelines doesn’t match our Indian people.

Jejak antikolonial kesusastraan Balai Pustaka dalam novel Sitti Nurbaya: Kasih Tak Sampai
Authors: Tjaraka Ajeng Rahayu , Tjahjandari Lily
Published: April 2024

In the creation of literary works, the author will always be influenced by the spirit of the times (Zeitgeist) that existed during the writing process. Sitti Nurbaya: Kasih Tak Sampai, a novel by Marah Rusli, is one of the literary works that is close to Minangkabau culture. It was first published in 1922 by Balai Pustaka. Balai Pustaka established strict regulations in publishing reading materials for people in the Dutch East Indies to stem the nationalism of indigenous peoples. This research aims to find the strategies used by Marah Rusli to convey the anticolonial discourse contained in the work. The method used in this study is a qualitative descriptive method with the sociology of literature approach and Stuart Hall’s concept of representation. The results that the researcher found in this study are the anticolonial traces conveyed by Marah Rusli using various strategies to escape the censorship of Balai Pustaka, namely (1) the construction of youth figures representing the modernity of the Dutch colonial government and the elderly representing the traditionality of indigenous people; (2) the portrayal of anticolonial attitudes through antagonistic characters; and (3) the use of the year of Hijri to deceive the Dutch colonial government.

This study focuses on the linguistic landscape in public transportation places in Sidoarjo Regency. It aims to analyze the use and function of language on signs at Sidoarjo Train Station, Waru Train Station, Purabaya Bus Station, Larangan Bus Station, and Juanda Airport. According to Spolsky and Cooper's theoretical framework, signs are classified based on various criteria forming language taxonomy on signs. The data collection was conducted using observation and interviews. The interview was conducted with one person (passenger) at each location and the observation lasted for four days for all locations, followed by data integration and analysis. The study identified 94 signs, including 62 monolingual (Indonesian and English) and 32 bilingual (Indonesian-English) signs functioning as prohibition, warning, labeling, direction, and information. The findings found the diverse linguistic landscape in the public transportation places in Sidoarjo Regency, which had an impact on communication and navigation for both domestic and foreign passengers. Furthermore, for future research, the researchers suggest using mixed methods for analysis and addressing specific areas, particularly enhancing the clarity and visibility of prohibition signs for passenger safety.

Published: April 2024

The Beji Antaboga tourist site provides a religious atmosphere full of tolerance by building various statues of religious symbols located in a forest in Banyuwangi. The harmony between humans and nature is very well maintained at this location. This nuance is supported by a fictional story that is believed by the local community, namely the Antaboga dragon. However, the place is fully taken care of by Hindus who are indeed attached to protecting the surrounding nature, and their commitment to guard several points of springs. This research aims to measure the inter-religious relations in the area and also to analyze the extent to which folklore as a discourse can be recontextualized as an effort to harmonize the bond of humans with nature. The research method used is qualitative, the first step applies the narrative structure of the story through actantial theory, the second is tracing the hypogram for the Antaboga story which dated back to Hindu’s teaching, and the last is looking at discourse as a power practice to recontextualize the harmonius reality. The finding shows Antaboga story is indeed to legitimise nature as the centre and not humans as the main actors.

Published: April 2024

One of the central components of cognitive diagnostic assessment is the Q-matrix, which is an essential loading indicator matrix and is typically constructed by subject matter experts. Nonetheless, to a large extent, the construction of Q-matrix remains a subjective process and might lead to misspecifications. Many researchers have recognized the importance of estimating or validating the Q-matrix, but most of them focus on the conditions of relatively large sample sizes. This article aims to explore Q-matrix validation possibilities under small sample conditions and uses regularized methods to validate the Q-matrix based on the compensatory reparametrized unified model and generalized deterministic inputs, noisy “and” gate models. Simulation studies were conducted to evaluate the viability of the modified least absolute shrinkage and selection operator (Lasso) and modified smoothly clipped absolute deviation (SCAD) methods, comparing them with existing methods. Results show that the modified Lasso and the modified SCAD methods outperform the stepwise, Hull, and MLR-B methods in general, especially under the conditions of small sample sizes. While good recovery in all small sample size conditions is not guaranteed, the modified methods demonstrate advantages across various item quality conditions. Also, a real data set is analyzed to illustrate the application of the modified methods.
