Tidal Disruption Encores
Authors: Ryu Taeho , Perna Rosalba , Cantiello Matteo
Published: April 2024

Nuclear star clusters (NSCs), made up of a dense concentration of stars and the compact objects they leave behind, are ubiquitous in the central regions of galaxies surrounding the central supermassive black hole (SMBH). Close interactions between stars and stellar-mass black holes (sBHs) lead to tidal disruption events (TDEs). We uncover an interesting new phenomenon: for a subset of these, the unbound debris (to the sBH) remains bound to the SMBH, accreting at a later time, thus giving rise to a second flare. We compute the rate of such events and find them ranging within 10−6–10−3 yr−1 gal−1 for SMBH mass ≃106–109
M
⊙. Time delays between the two flares spread over a wide range, from less than a year to hundreds of years. The temporal evolution of the light curves of the second flare can vary between the standard t
−5/3 power law to much steeper decays, providing a natural explanation for observed light curves in tension with the classical TDE model. Our predictions have implications for learning about NSC properties and calibrating its sBH population. Some double flares may be electromagnetic counterparts to LISA extreme-mass-ratio inspiral sources. Another important implication is the possible existence of TDE-like events in very massive SMBHs, where TDEs are not expected. Such flares can affect spin measurements relying on TDEs in the upper SMBH range.

Introduction: Congenital syphilis (CS) has severe adverse outcomes, including abortion and death. Diagnosis of CS in asymptomatic newborns remains difficult. This study aims to evaluate an in-house polymerase chain reaction (PCR) on cerebrospinal fluid (CSF) and blood samples (BS) to identify T. pallidum DNA in newborns.
Methodology: We performed an exploratory cross-sectional study that included newborns exposed to syphilis during pregnancy (SEG) and non-exposed (SNEG) newborns, between 2019 and 2020. In-house conventional PCR for T. pallidum targeting the tpp47 gene was used to analyze CSFS and dried blood spots.
Results: BS was obtained from 54 newborns (33 SEG/21 SNEG) and CSF from 55 newborns (33 SEG/22 SNEG). Twenty-five (71.4%) SEG newborns had reactive BS rapid plasmatic reagins (RPR), and all of them had RPR titers less than or equal to the corresponding maternal titers. All RPR CSF tests were negative. PCR for T. pallidum DNA was positive in 19/33 (57.6%) BS, and in 22/33 CSF. The only SEG newborn with clinical signs of early CS had a positive CSF PCR and a negative BS PCR. Conversely, among SNEG newborns, PCR was positive in 2/21 BS and 5/22 (22.7%) CSF.
Conclusions: T. pallidum DNA was identified using our PCR tests. The exposed group did not present abnormalities that would indicate CS. This prevented conclusions regarding sensitivity and specificity. Dried spot permitted bedside collection, easy transportation, and storage. Further research is needed to evaluate and improve the accuracy of CS low-cost PCR tests, especially for limited resource settings.
Allergic bronchopulmonary mycosis due to Schizophyllum commune in a patient with chronic hepatitis B
Authors: Xu Rui , Zhang Jianfeng , Zheng Jiangnan , Wu Qiaozhen
Published: April 2024

Introduction: Schizophyllum commune (S. commune) is an opportunistic pathogenic fungus and can cause infection of the respiratory system in immunocompromised hosts. Allergic bronchopulmonary mycosis (ABPM) is the major disease caused by S. commune. However, identification of S. commune using routine mycological diagnostic methods is difficult. It is easy to make mistakes in diagnosis and treatment, resulting in deterioration of the disease. We report the first case of ABPM due to S. commune in a Chinese patient with chronic hepatitis B.
Case presentation: The patient presented cough, sputum and dyspnea for six months. The pathogen was missed during routine laboratory workup. We performed bronchoscopy examination and bronchoalveolar lavage. S. commune was identified by metagenomic next-generation sequencing (mNGS) of bronchial alveolar lavage fluid (BALF). Hence, the patient was immediately treated with 200 mg voriconazole twice daily (intravenous infusion) and 20 mg prednisone once a day (oral therapy), along with oral entecavir for hepatitis B. There was no recurrence of infection after the medication was discontinued.
Conclusions: S. commune infection should be considered in the diagnosis of patients with refractory cough, sputum and dyspnea, especially in immunocompromised individuals. The mNGS technique is an effective supplementary technique for the diagnosis of S. commune infection, enabling precise clinical decision-making and appropriate treatment. Most patients have good prognosis with a combination of proper antifungal therapy and hormonal therapy.

Published: April 2024

Introduction: The distribution of common subtypes of hepatitis C virus (HCV) in Gansu province were analyzed. This information provided a theoretical basis for the selection of appropriate antiviral treatment regimens.
Methodology: We collected data on HCV antibody screening tests from 421,802 outpatients and inpatients at the Second Clinical Hospital of Lanzhou University from January 2018 to June 2022. Ribonucleic acid (RNA) viral load, HCV genotypes, and HCV quantification were analyzed retrospectively. The results of HCV positive detection rate, copy number, and genotype distribution were statistically analysed using SPSS 26.0.
Results: A total of 421,802 HCV antibody screenings were performed resulting in 4,558 positive cases (1.081%). In addition, 2,345 cases (1.302%) were positive with quantitative HCV antibodies in 180,157 outpatients and inpatients. Quantitative HCV virus RNA was further measured in 2592 outpatients and inpatients. There were 825 positive cases for HCV, with a positivity rate of 31.83%. High-sensitivity quantification of HCV-RNA was performed in 6538 patients, among which 1336 were HCV-RNA positive infections (positivity rate of 20.43%). Among the 1484 genotype tests, 4 genotypes and 10 subtypes were detected, including 4a, 1b, 2a, 2b, 3a, 3b, 6a, 6n, 1b/2a, and 2a/6a, with the majority of results from 2a (51.89%) and 1b (42.72%).
Conclusions: The most prevalent genetic subtype in HCV-positive patients in Gansu was 2a, followed by 1b. In addition, 8 genotype subtypes appeared: 1a, 2b, 3a, 3b, 6a, 6n, 1b/2a and 2a/6a. Understanding the distribution of HCV genes in Gansu province is of significance for the optimization of virus treatment.

Authors: Al Sulayyim Hadi , Ismail Rohani , Al Hamid Abdullah , Mohammed Bazuqamah , Abdul Ghafar Noraini
Published: April 2024

Introduction: Prevalence of antibiotic resistance (AR) during the coronavirus 2019 (COVID-19) pandemic was higher than pre-pandemic times. This study determined the prevalence and patterns of AR among Gram-positive and negative bacteria before, during and after COVID-19 in Saudi Arabia and identified the associated factors.
Methodology: A retrospective cross-sectional study was employed to identify patients with positive AR bacteria between March 2019 and March 2022. The bacterial isolates and patients’ data were identified from laboratory and medical records departments retrospectively. Binary logistic regression analysis was performed to identify the factors associated with AR and deaths. Multinominal logistic regression was applied to confirm the factors associated with AR classification.
Results: AR Gram-negative bacteria decreased during and after the pandemic. However, S. aureus showed a negligible increase in resistance rate after pandemic, while E. faecium, recorded a higher-than-average resistance rate during the pandemic. The prevalence of pan drug resistance (PDR) during the pandemic (85.7%) was higher than before (0%) and after (14.3%), p = 0.001. The length of stay and time were significant predictors for AR classification. The odds of multi drug resistance (MDR) development to PDR during the pandemic were 6 times higher than before and after (OR = 6.133, CI =, p = 0.020). Age, nationality, COVID-19 infection, smoking, liver disease, and type and number of bacteria were associated with death of patients with positive AR.
Conclusions: Further studies are recommended to explore the prevalence of PDR and to justify the increased rates of E. faecium AR during the COVID-19 pandemic.

Members of Brassica seed oil are important sources of nutritionally superior edible oil. There are no comprehensive reports on complete lipidomic profile of these oilseed crops. In this study, the lipidomic profiling of edible oil from 7 different cultivated species of Brassica seed oils was performed by shotgun approach using electrospray High Resolution Time of Flight-Mass Spectrometry (ESI-ToF-MS). The mass spectrum under positive polarity revealed 1098 lipids under different lipid classes including sphingolipids, phospholipids and different storage lipids. Under negative polarity, 70 lipids including free fatty acids (FFA), cardiolipins and phospholipids were detected. Erucic acid in FFA form was found to be most abundant in both Yellow and Brown sarson. Brassica napus contains almost all forms of cardiolipins (CL). Out of 26 different species of cardiolipins detected in negative ion mode, CL 56:1 (FA 18:1) and CL 56:1 (FA 22:1) were present only in brown sarson. Similarly, CL 56:2 (FA 18:2) and CL 56:1 (FA 22:1) were present only in Yellow and Brown sarson. These findings enhance our understanding of the nutritional diversity in Brassica seed oils, emphasizing the significance of lipidomic analysis for elucidating the molecular composition of edible oils.

Les enfants font très tôt la différence entre l’amour et l’amitié comme s’ils disposaient de proto-représentations quasi d’emblée différenciées de ces deux états psychiques fondamentaux. Mais peut-être pressentent-ils aussi très vite la place particulière qu’occupe l’amour dans l’esprit des adultes qui prennent soin d’eux avec sa charge de mystères et d’interdits… Penser la différence entre l’amour et l’amitié sous le seul angle des processus de sublimation et de désublimation a quelque chose d’insuffisant. L’auteur tente de montrer que l’amour et l’amitié n’impliquent sans doute pas les mêmes niveaux de la représentation d’objet, mais aussi que la problématique de «  l’Amour fou  » peut, quant à elle, tout à fait concerner les bébés et qu’enfin les questions de l’amour et de l’amitié ne sont pas entièrement clivables compte tenu de la dose de passion qui peut plus ou moins souvent infiltrer l’amitié aussi bien quand elle précède l’amour que quand elle lui succède.

L’enquête se déroule en trois temps. Le premier, avec l’ Histoire de la sexualité de Michel Foucault, nous plonge dans l’Antiquité grecque classique. Foucault analyse finement la relation entre un adulte et un adolescent, faite à la fois d’amour et d’amitié. Il décrit cette relation complexe d’une cour amoureuse que Platon conçoit ensuite en tant qu’érotique philosophique. Dans le second, je remarque comment la pédérastie grecque, que les anciens Grecs valorisaient socialement apparaît aujourd’hui comme une nouvelle figure historique, celle de la pédocriminalité. Dans le troisième, je fais retour à Foucault, avec la notion de bien-être et l’analyse comparative entre le souci de soi antique et le culte de soi contemporain.

Le «  coup de foudre  » qui signe la puissance des affinités électives repose sur la fascination de chacun des protagonistes face à leur mouvement de dessaisissement narcissique envers l’autre. Mais, dès le moment où un couple a constitué une unité isolée, il court le même risque d’étouffement que l’individu et il lui faut sortir de soi pour ne pas tomber malade par stase libidinale, autrement dit par ennui. L’addiction au risque d’aimer à nouveau ailleurs se présente alors, conséquence de l’incapacité à élaborer au sein du couple ce qui peut tenir la place de l’autre. Partant de Goethe et de Stendhal, on interroge ici l’incapacité à se détacher du risque passionnel en la confrontant à la nécessité qu’éprouvent certains sujets de miser leur vie pour la vivre intensément. Face à cette quête narcissique infinie, l’objet se limite à sa capacité de faire défaut, ce qui le rend apte à figurer à l’extérieur du Moi le manque autour duquel il s’organise.
An interpretable mechanism for grating-induced cross-inhibition and gamma oscillation based on a visual cortical neuronal network model
Authors: Yang Hao , Wang Peihan , Han Fang , Wang Qingyun
Published: April 2024

Biological experiments targeting the mammalian primary visual cortex have shown that neuronal response to a preferred orientation grating is cross-inhibited by an orthogonal orientation mask grating. The plaid formed by the overlap of the two gratings not only causes a decrease in the neuronal firing rate but also shifts the gamma oscillation to a weaker oscillation at a higher frequency. The mechanism for the above phenomena is unclarified. In this paper, a large-scale cortical neuronal network model with biological details is constructed. In this model, two modes of connectivity that may contribute to cross-inhibition are considered: the thalamo-cortical feedforward pathway and the push-pull organization of cortical layer 4. Based on this model, the modulation of firing rate and gamma oscillation by a plaid stimulation are successfully reproduced, which is consistent with biological experiments and suggests that it is the thalamo-cortical feedforward pathway that leads to cross-inhibition. Furthermore, our analysis of the neuronal spike clusters and current fluctuations suggests that the push-pull organization leads to an increase in gamma frequency during the transition of visual stimuli from grating to plaid by modulating the source of synaptic inhibition in local neuronal populations. Such results will help to understand the visual processing under multi-input integration.
The measurement of financial support for real estate and house price bubbles and their dynamic relationship: An empirical study based on 31 major cities in China
Authors: Gao Ying , Yang Hui
Published: April 2024

In recent years, China's real estate prices have continued to rise, preventing the bursting of the house price bubble, and the various risks it triggers has become an important issue that governments at all levels have to face. In this paper, the backward sup ADF (BSADF) method was used to dynamically portray the evolution of real estate price bubbles in 31 large and medium-sized cities in China over a period of 11 years, from 2013 to 2021, and the dynamic relationship between the degree of financial support for real estate (hereinafter referred to as financial support) and house price bubbles in cities was investigated by employing a panel vector autoregressive (PVAR) model with panel data. The results showed that: Multiple cyclical bubbles significantly existed in the real estate markets of the cities during the study period, and in general, house price bubbles appeared earlier in the more economically developed regions than in the less economically developed regions and have spread to the less economically developed regions. Financial support contributed to house price bubbles, supporting the theory of excessive financial support. Furthermore, the results of the sub-sample showed that financial support contributed most strongly to house price bubbles in cities in the northern region.
“En avant” : le mot‑clé d’un champion olympique comme instrument psychologique pour l’action sportive
Authors: Laurin-Landry Arnaud , Merri Maryvonne
Published: April 2024

Dans cet article, nous mettons en action une nouvelle conceptualisation du discours interne à l’aide des méthodes d’analyse élaborées dans un précédent article. Pour ce faire, nous analysons le mot-clé « En avant » que William, champion olympique de ski de bosses, se dit lorsqu’il fait un salto arrière double vrille sur le saut du haut. La description des différentes propriétés du mot-clé « En avant » nous conduit à proposer les trois effets d’un mot-clé : 1) le mot-clé fait apparaître une fonction langagière au sein d’une activité motrice, 2) le mot-clé prend en charge le déploiement des différentes actions possibles et actualise le choix de la bonne action, 3) le mot-clé permet l’apparition d’une rétroaction en direct sur l’action se produisant. La discussion de cet article montre comment les effets du mot-clé n’existent pas en soi dans le mot dit, ils existent par le rapport dialectique entre l’athlète et le mot-clé et sont le produit d’un développement.
Intervenir en situation de crise sociale : l’ergonomie pour créer les conditions d’un dialogue sur le travail
Authors: Pentecôte Baharak , Mollo Vanina , Gaillard Irène
Published: April 2024

Cet article est issu d’une intervention ergonomique menée au sein d’un établissement hospitalier en proie à une crise sociale. L’objectif était de comprendre l’origine de la crise pour élaborer un diagnostic partagé, et de créer les conditions pour mettre le travail réel au centre des débats et des décisions. Les tensions sociales ont directement impacté la démarche et ont conduit les ergonomes à ajuster leur méthodologie. L’article présente le modèle de compréhension de la crise sociale qui a été co-construit. Il décrit également les ajustements méthodologiques opérés pour faire face aux contraintes de la crise sans cesse renouvelées. Enfin, il montre comment ces ajustements ont permis à la fois de créer les conditions d’un dialogue sur le travail, dans un climat apaisé et d’écoute mutuelle, et d’agir sur le travail.
La contribution des usagères dans un atelier de co‑idéation : une médiation sociotechnique pour l’exploration des niveaux épistémiques d’un projet

Published: April 2024

Cette étude porte sur l’activité de « co-idéation » lors d’un projet de design intérieur. Nous entendons par co-idéation un engagement actif des usagères dans la phase initiale du processus de conception, caractérisée par la génération de propositions de design. Cette approche vise à expliciter leur activité d’usage (actuelle et projetée) en amenant les usagères à appréhender directement un système de représentation et l’espace réel. N’étant pas formées en design, leur contribution nécessite une médiation sociotechnique. Dans cette étude, trois groupes d’usagères collaborent avec des professionnelles de la conception, chargées de stimuler la génération d’idées et de faciliter l’utilisation du système de représentation. Nous cherchons à identifier les contributions des participantes (usagères et médiatrices) par la nature des connaissances mobilisées et construites, que nous structurons en sept « niveaux épistémiques », de l’abstrait au concret. Nous analysons si leur traitement diffère selon la mobilisation du système de représentation, la catégorie des participantes et les tactiques de médiation. L’étude montre que tous les niveaux épistémiques sont explorés, dans une proportion moindre pour ce qui concerne les valeurs et les décisions techniques concrètes. Le positionnement des groupes dans l’espace réel influence leurs propositions et le niveau le plus exploré. Nous identifions plusieurs tactiques de médiation : injonction à la cohérence, impulsion de mouvements verticaux et latéraux. La modélisation d’une tactique de médiation montre la dynamique du soutien apporté. Cette étude établit un cadre théorique opérationnel pour la formation et la médiation de la co-idéation et permet d’élaborer de nouvelles pistes de recherche.

En réponse aux enjeux de durabilité et de transitions dans le monde agricole, de nombreux acteurs, scientifiques et acteurs de la R&D et du conseil agricole, conçoivent des outils ou des services visant à aider les agriculteurs à faire évoluer leurs pratiques agricoles. Ils souhaitent un appui pour intégrer les futurs utilisateurs dans ces processus de conception. Dans cet article, nous confrontons deux interventions que nous avons réalisées auprès de ces acteurs en phase d’exploration d’idées d’outils ou de services, c’est-à-dire très tôt dans la conception. Nous présentons les projets dans lesquels nous sommes intervenus, et la façon dont nous avons représenté l’activité des utilisateurs potentiels afin d’aider les concepteurs à repenser profondément les outils et services imaginés pour soutenir les transitions agroécologiques des agriculteurs. Deux axes ont été privilégiés par nous : une représentation de la diversité des logiques d’action des agriculteurs, une mise en exergue de la dimension systémique et collective des activités à outiller (au sens où elles impliquent bien d’autres acteurs que les agriculteurs). Nous présentons les nouvelles explorations que notre démarche suscite. Nous discutons des enjeux d’évaluation des effets que les supports et plus largement notre démarche ont pu avoir sur la transformation de l’activité des concepteurs. Nous ouvrons également la discussion en pointant la nécessité pour les ergonomes de se doter de méthodes pour représenter une activité en transformation comme celles que mettent en œuvre les agriculteurs qui s’engagent dans des transitions agroécologiques.
RELAÇÃO ENTRE ESTADOS DE HUMOR E A PERCEPÇÃO TÉRMICA DE PEDESTRES

Published: April 2024

Estudos têm revelado que aspectos psicológicos como os desencadeados pelos estados de humor podem influenciar a avaliação térmica subjetiva. Investiga-se se o estado de humor reportado durante as entrevistas de conforto térmico é fator psicológico que influencia a percepção térmica de pedestres em ambientes externos. Conduziu-se o monitoramento de ambientes térmicos com a aplicação de questionários em locais ao ar livre na cidade de Cuiabá-MT (Brasil), região com clima tropical. O voto de sensação térmica (VST) segmentado em função do Estado de Humor reportado (neutralidade, positividade e negatividade) foi correlacionado às condições térmicas, expressas pelo índice UTCI. Evidenciou-se maior sensibilidade térmica nos indivíduos pertencentes ao grupo com humor negativo, indicando que estes sentem mais calor à medida que o estresse térmico se eleva, desejam ambientes mais amenos e se declaram desconfortáveis nessas condições, comparativamente a aqueles pertencentes aos grupos neutro e positivo. Maior temperatura neutra e maior coeficiente angular, derivados da curva de tendência linear obtida entre UTCI e VST, ratificam esse comportamento do grupo negativo. A variância entre as condições ambientais e os estados de humor não explicou a variação na sensação térmica nos grupos, devendo-se considerar outros fatores intervenientes na percepção térmica.

Published: April 2024

Leadership is both a concept and practice that involves several criteria including individual characteristics, communication skills, decision-making, and relationship with subordinates. There are a variety of leadership styles that exist today. Some of these styles concentrate on the hierarchy and power of the position, while yet others focus more on the relationship to followers to achieve results. One such leadership style is the coaching leadership style (CLS). This chapter provides an in-depth understanding of CLS including its origins, characteristics, necessary skills, and connections. Related and opposing leadership styles are also discussed for enhanced content of the approach. Both an examination of the advantages and disadvantages of applying a coaching leadership style, and how one learns to be an effective coaching leader is provided. Further discussion on effective situations and follower readiness for CLS is also given. This chapter concludes with a final look at four practicing coaching leaders and what we can learn from their examples.

Published: April 2024

The study explained in this chapter introduced the Jigsaw-PBL teaching method to students and measured their perceptions, satisfactions, and motivations through a survey. The study found that the Jigsaw-PBL approach is effective in teaching IS-AD, leading to more efficient syllabus coverage, improved students engagement, interaction, and mastery. Students perceive the Jigsaw-PBL method as appropriate for fostering teamwork and promoting peer-to-peer learning. However, challenges such as differences in class schedules, concerns about the time required for the Jigsaw-PBL approach, and a preference for traditional teacher-centred learning are reported. The study emphasizes that the Jigsaw-PBL approach promotes active learning, critical thinking, communication, teamwork, and problem-solving skills, making it a powerful learning and teaching pedagogical approach for students to develop technical knowledge and critical soft skills. This study provides valuable insights into the potential of the Jigsaw-PBL approach in low-income countries and its role in enhancing students' employability.

Group-Oriented Multi-Attribute Decision-Making Method Based on Dominance Rough Set Theory
Authors: Bin Yu , Zeyu Xiao , Yinglong Dai
Published: April 2024

This chapter proposes group-oriented multi-attribute decision-making based on mixed advantage-disadvantage degree (GOMADMMADD) method to deal with group-oriented decision analysis. Based on the strict attribute relationship between group members, this method proposes the concepts of “local advantage-disadvantage degrees” and “advantage-disadvantage degrees,” which solves the challenge of group-oriented multi-attribute decision-making (GOMADM). However, this method still has the problem that the number of groups to be evaluated increases exponentially. Therefore, the authors first improved the GOMADMMADD method and proposed decision-making method based on dominance-based rough sets (GMADMDRS). Then, the “advantage” neighborhood operators and “disadvantage” neighborhood operators of groups are introduced to define the “advantage-disadvantage neighborhood degree” (ADND), and the GMADMDRS method is optimized by using ADND. The experimental results show that both GOMADMMADD method and GMADMDRS method effectively evaluate the population, and the optimized GMADMDRS algorithm is consistent in the experimental results, and the time performance has been greatly improved, and the computational performance has been significantly improved, which has practical significance to solve the problem of exponential growth of the number of groups to be evaluated. These methods provide a novel perspective and effective method for group oriented multi-attribute decision-making.
Decision-Making Based on Partition Order Product Space
Authors: Xu Yi
Published: April 2024

Granular computing focuses on structured thinking and problem solving, which solves complex problem based on granular structure. Existing studies on granular structures mainly focus on multilevel granular structure and multiview granular structure respectively, without combining multilevel granular structure and multiview granular structure. In order to describe and solve problem in a more effectively and reasonably way, we propose partition order product space by combining multilevel granular structure with multiview granular structure. To obtain a solution for problem solving in partition order product space, we propose two search algorithms: depth-first searching algorithm and breadth-first searching algorithm. From the viewpoint of granular computing, existing three-way decisions cannot effectively combine multiview and multilevel to make decisions. As the partition order product space follows the principles of multiview and multilevel, we discuss three-way decisions based on partition order product space. We propose four multiview sequential three-way decisions.

Published: April 2024

Supplier selection, which is one of the phases of supply chain management, was examined in this chapter. In the line of four expert opinions and literature review, four main criteria, including environmental, economic, social, and smart criteria, and 18 sub-criteria were evaluated in this study. An interval-valued q-rung orthopair fuzzy (IVqROF) number based MAIRCA (multi attributive ideal-real comparative analysis) method is proposed for the ranking of 5 alternative suppliers. In this chapter, fuzzy number was proposed for the MAIRCA method, but unlike the literature, IVqROF number was applied to the MAIRCA method. It has been seen that the IVqROF number, which is the extension of the q-rung orthopair fuzzy number obtained by developing the intuitionistic fuzzy number and the Pythagorean fuzzy number, provides an advantage in evaluating expert opinions. In addition, Industry 4.0 criteria were examined under the smart criterion and contributed to the supplier selection problem. The study examined the smart supplier selection problem of an automotive sub-industry company.

Published: April 2024

Global cyber dangers related to phishing emails have increased dramatically, particularly after the COVID-19 epidemic broke out. Many companies have suffered significant financial losses as a result of this kind of assault. Even though many models have been developed to distinguish between phishing efforts and genuine emails, attackers always come up with new ways to trick their targets into falling for their scams. Many companies have suffered significant financial losses as a result of this kind of assault. Although phishing detection algorithms are being developed, their accuracy and speed in recognizing phishing emails are not up to par right now. Furthermore, the number of phished emails has concerningly increased lately. To lessen the negative effects of such bogus communications, there is an urgent need for more effective and high-performing phishing detection algorithms. Inside the framework of this study, a thorough examination of an email message's email header and content is carried out. A novel phishing detection model is built using the features of sentences that are extracted. The new dimension of sentence-level analysis is introduced by this model, which makes use of K Nearest Neighbor (KNN). Kaggle's well-known datasets were used to both train and evaluate the model. Important performance indicators, including as the F1-measure, precision, recall, and accuracy of 0.97, are used to assess the efficacy of this approach.

Published: April 2024

This chapter examined the profound influence of data science and volunteered geographic information (VGI) on the delivery of public services. Volunteered geographic information (VGI), being material created by users, has had a substantial impact on making geographic information accessible to everybody, enabling people to actively engage in the creation and management of data. The incorporation of volunteered geographic information (VGI) into government operations has introduced novel prospects for enhancing service provision in diverse sectors such as education, health, transportation, and waste management. In addition, data science has enhanced VGI by using sophisticated methodologies like artificial intelligence (AI), internet of things (IoT), big data, and blockchain, thereby transforming the whole framework of government service provision. Nevertheless, in order to effectively use VGI in public sector services, it is essential to tackle significant obstacles such as data accuracy, safeguarding, inclusiveness, technical framework, and specialized expertise. The quality of VGI data may be improved by collaborative endeavors including governments, volunteers, and academics.

Recent studies indicate that bio-oil production from EFB is highly influenced by the temperature during pyrolysis. In this study the pyrolysis process was conducted at the optimum temperature of 500°C for 60 minutes and the nitrogen gas flowrate (N2) was varied between 1 and 3 L/min. The bio-oil itself can be obtained from the condensed gas pyrolysis product. The characteristics of bio-oil were then identified based on biofuel quality standards. The bio-oil was then tested in order to determine its physical properties such as its density, water content, and acid number. Besides, the chemical components of the bio oil were identified by using GC-MS. The results show that the density of bio-oil is within the range of 0.9918 - 1.0083 g/cm3. The highest water content produced is 27.22% at a flow rate of 1 L/min. The acid number of bio oil is ranging from 124.9 – 139.6 mg KOH / g. According to GCMS test results, linoleic acid content is high at a flow rate of 1 L / min, while hexadecane content dominates by 15.79% at a 2 L / min rate. Further observation on the rate of 3 L / min shows that phenol content increases.

Silver (Ag) is one of the heavy metal wastes in the silver industry. Silver metal (Ag) contamination has an impact on human health and the environment so that a metal waste treatment method is needed to minimize the impact. This study used coffee grounds as an adsorbent for silver metal (Ag). The purpose of this study was to determine the characteristics of the adsorbent functional groups, adsorption time stability, optimum adsorbent mass, type of adsorption isotherm, and adsorption free energy (ΔGoAds). Activated carbon was prepared through three processes, namely baking at 110 oC for 2 hours, carbonization at 400 oC for 3 hours, and activation with 1 M H3PO4 for 24 hours. The characterization of the adsorbent was carried out using Fourier Transform Infrared Spectroscopy (FTIR). The results of the adsorbent characterization indicated the presence of functional groups, namely, C-H(Csp3), aromatic C=C, -CH3, and P=O from the remaining H3PO4 activator which experienced a shift in absorption as the adsorbent was treated. The results of this study showed that the stability of Ag adsorption time was 60 minutes and the optimum adsorbent mass was 1 gram. Adsorption isotherm type of metal Ag is Freudlich isotherm with linear equation y = 0.9084x + 0.6272 and R2 value of 0.9219. Isotherm Freudlich provides information on the n value of 1.1008 and KF of 4.238 L/mg. Calculation of adsorption free energy (ΔGoAds) obtained a value of-12.395 kJ/mol so that the adsorption process occurs physically.

Molecular Simulation of Coffee Beans’ Natural Products as Lead Compounds for Stroke Remedy
Authors: Rubani Muhammad , Parikesit Arli Aditya
Published: April 2024

The consumption of coffee has its health benefits and its risks, one of the risks is mostly related to cardiovascular diseases. One of the diseases is hypertension which is considered “the silent killer” as it is a serious condition which promotes other complications and typically has no symptoms for a period of time until it has done significant damage. Acute hypertension can lead to a stroke. It is a very serious medical condition where the blood flow to the brain is poor, causing the death of cells within the brain. Some medications, surgeries and other healthcare programs are capable of controlling stroke, but stroke still remains to be the main cause of death and disability in Indonesia. However, provided that the consumption is restrained, multiple studies show that coffee consumption actually can reduce the risk of getting a stroke, by consuming between 2 to 4 cups of coffee per day. Additionally, coffee can reduce the likelihood of blood clots from forming and is likely to alter the blood vessel physiology. Therefore, the current project will explore the possibility of utilization of bioactive compounds other than caffeine from coffee beans that can be implemented in a form of supplements to help in treating patients both with stroke symptoms and during the recovery phase. Protein docking analysis is an alternative way to search and predict for drug discovery. Through protein docking analysis we can gain information on the bioactive compounds and their respective interactions with the target. Based on the virtual screening pipeline, it is predicted that Dehydrokahweol could elicit possible lead for the anti-stroke activity.
