Visualisations for Bayesian Additive Regression Trees
Authors: Inglis Alan , Parnell Andrew , Hurley Catherine
Published: February 2024

Tree-based regression and classification has become a standard tool in modern data science. Bayesian Additive Regression Trees (BART) has in particular gained wide popularity due its flexibility in dealing with interactions and non-linear effects. BART is a Bayesian tree-based machine learning method that can be applied to both regression and classification problems and yields competitive or superior results when compared to other predictive models. As a Bayesian model, BART allows the practitioner to explore the uncertainty around predictions through the posterior distribution. In this paper, we present new Visualisation techniques for exploring BART models. We construct conventional plots to analyse a model’s performance and stability as well as create new tree-based plots to analyse variable importance, interaction, and tree structure. We employ Value Suppressing Uncertainty Palettes (VSUP) to construct heatmaps that display variable importance and interactions jointly using colour scale to represent posterior uncertainty. Our new Visualisations are designed to work with the most popular BART R packages available, namely BART, dbarts, and bartMachine. Our approach is implemented in the R package bartMan (BART Model ANalysis).

During the Covid-19 pandemic, contact-tracing apps have offered effective help to bend the contagion curve. Thus, it is of critical importance to understand the factors that influence contact-tracing apps’ adoption among citizens. In particular, the successful adoption and usage of contact-tracing apps strongly relies on individual motives. Therefore, this study draws on the theory of altruistic and egoistic motivation for prosocial behaviours to analyse the underlying motives through which citizens engage in voluntary behaviours aimed at using and promoting the use of contact-tracing apps. The study also examines the mediating role of users’ trust in the app. Data from 221 users of Ireland’s Covid Tracker app was analysed. Structural equation modelling with PLS was used to test the research model. Findings show differences between egoistic and altruistic motivation in promoting app use and sharing. Egoistic motivation significantly promotes voluntary behaviours among citizens and users’ trust in the app mediates this influence. Yet, contrary to predictions, in the context of the pandemic, altruistic motivation does not play a significant role in engaging citizens in these voluntary behaviours, either directly or indirectly. The findings of this study are important for policy makers and may inform future policy decisions regarding the implementation of contact-tracing apps in the case of new pandemics or for other contexts requiring cooperative daily check-in.
La retribuzione in Italia è proporzionale e sufficiente?
Authors: Mandrone Emiliano
Published: February 2024

Wages in Italy are very low: in nominal terms compared to other European countries and in real terms due to the recent inflationary flare-up, the inadequate and late contractual adjustments process and, finally, to the heterogeneity of the cost of living between territories. The phenomenon of working poor is increasingly relevant. There is now a pressing need to restart overall pay dynamics and to support workers in low-quality jobs and low wages. Analyses are presented on the economic levels of work, both for employees and for jobseekers, because the issue of low labour participation closely linked to the level of wages is also a longstanding one. Reserve and reputational wage measures are proposed, useful for defining the threshold of acceptable work, and data on intermediation, to see how many vacancies are contestable. The quality of pay and employment represent our level of civilization of work.

Published: February 2024

The Archean Tati greenstone belt is located at the southwestern margin of the Zimbabwe craton (northeast Botswana) and hosts numerous Cu-Ni ± platinum group element (PGE) and Au ± Ag occurrences and deposits. Gold occurrences/deposits are poorly studied, and key questions pertaining to their genesis remain unclear, including the mode of occurrence(s) of gold, the relative timing of gold introduction with respect to the evolution of the greenstone belt, the number of gold mineralization events, the alteration patterns, and the relationships between each alteration pattern and gold mineralization. A detailed study that includes sulfide and gold grain chemistry using laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) and electron probe microanalysis (EPMA), respectively, and X-ray diffraction (XRD) of mineralized rock samples of three Tati greenstone belt gold deposits was carried out to constrain the genesis of gold mineralization and formulate exploration guidelines in the Tati greenstone belt. Gold in the Tati greenstone belt is the result of multiple events, is mainly associated with arsenopyrite, pyrite, and sphalerite, and occurs as (1) microinclusions within sulfides, (2) intergrowth with sulfides, (3) minute particles (<2–10 µm) within the silicate matrix, (4) microfractures and microvug infills, and (5) lattice-bound and sulfide-hosted refractory gold. The first gold event (as electrum) is premetamorphic and associated with sphalerite-quartz veins. The second stage is a postmetamorphic high-grade gold event that is accompanied by extensive carbonatization and propylitization of host rocks. The third stage of gold mineralization is marked by the dissolution of gold in the early formed stages 1 to 2 and subsequent reprecipitation within cracks, fractures, and vugs. Auriferous pyrite composition suggests that Au-bearing mineralizing fluids are predominantly of magmatic origin and that their physicochemical compositions changed during the mineralization process, as supported by chemically zoned Au-bearing arsenopyrite, various alteration types containing gold, and variation in gold fineness across the several gold deposits in the Tati greenstone belt. Gold deposition in the Tati greenstone belt mainly occurred through sulfidation, as indicated by the closest spatial association between gold and Fe-bearing sulfides and ferromagnesian silicates. Gold in the Tati greenstone belt is closely correlated with As, Sb, Pb, Bi, Ni, Hg, Tl, Cd, In, Mo, W, Zn, and Te and moderately to weakly associated with Sn, Se, Cr, Co, Ge, Cd, Mn, V, Ga, and Ag. The correlation between Au and fluid mobile elements, i.e., Te, Sb, Se, As, Hg, and Bi, can be used as a vectoring tool during the exploration of gold within the Tati greenstone belt, as these elements likely form halos that are much broader than the primary footprint of gold mineralization.

Published: February 2024

Objectives. The urinary tract infections (UTIs) is the most common type of infection, after respiratory tract infections, being more common in women, approximately 50-60% of whom have at least one episode of UTI during their lifetime. Other risk factors are old age, diabetes, kidney stones, urinary tract obstructions, and procedures such as urinary catheterization. Uropathogenic strains of E. coli are most commonly implicated in the etiopathogenesis of UTI, other pathogens being represented by Proteus mirabilis, Staphylococcus saprophyticus, Staphylococcus epidermidis, Klebsiella pneumoniae, group B streptococci (involved, for example, in UTI in patients with diabetes mellitus) and Pseudomonas aeruginosa (found in patients who underwent urinary catheterization). The study aimed to test the sensitivity at antibiotics of bacteria isolated from urine samples of patients with urinary tract infections from a medical analysis laboratory, in the period 2022-2023. Methods. The urine samples obtained were initially analyzed macroscopically, from the point of view of turbidity and chromatic aspect. Later, they were centrifuged and examined under an optical microscope to assess the cellularity. Sectors were sown from the urine samples on CLED, CPS and bile-esculin culture media. After being seeded, the plates were introduced to the thermostat, where they were left for 24 hours at 36-37 °C. The antibiotic susceptibility of the bacterial strains was tested by means of the diffusimetric method, using special Muller-Hinton media. Results. The most common pathogen isolated in urine cultures was E. coli 83%, followed by Klebsiella pneumoniae (7%) and Enterococcus spp. (4%), 3 strains of Proteus mirabilis, 2 of Klebsiella oxytoca and 1 of Proteus vulgaris were also isolated. Regarding the susceptibility at the tested antibiotics, it has been obtained the following results: to AmoxicilinClavulanic Acid-77% Gentamicine-96%, Nitrofurantoin-88%, Trimethoprime/Sulfamethoxazole- 79% Cefazolin-71%, Cefuroxime-81% Levofloxacine-92%, Ciprofloxacine-91%, Norfloxacine-83%, Fosfomycin-99%. Conclusions. The isolated strains showed more than 90% sensitivity to Gentamicine, Levofloxacine and Ciprofloxacine. Also, an increased sensitivity (over 80%) was recorded to Cefuroxime and Nitrofurantoin.

Due to the degradation of the muscles and elastic connective tissues, bronchiectasis is characterized by a chronic enlargement of the bronchi and bronchioles. The condition is characterized by an ongoing cough, the production of sputum, and infections and can strike at any age. Bronchiectasis may have been less frequent in the 20th century, but it still ranks third among the chronic inflammatory disorders of the airways, behind chronic obstructive pulmonary disease and asthma. Pseudomonas aeruginosa and Haemophilus influenzae are the most frequent bacteria detected in bronchiectasis airways worldwide, but proportions differ amongst bacterial communities. Additionally, Streptococcus, Prevotella, Veillonella, and Staphylococcus have been found in bronchiectasis patients' airways. The symptoms of bronchiectasis, which include worsened sputum production with more blood and purulent discharge, wheezing and dyspnea, as well as fever, are considered to be brought on by bacterial infection. On thin-section CT scans, morphologic criteria include the presence of bronchi within 1 cm of the pleural surface and bronchial dilatation in relation to the adjacent pulmonary artery (signet ring sign). The basic objectives of bronchiectasis care are to preserve adequate lung function, regulate symptoms and enhance patient quality of life while preventing and reducing exacerbations.
MANAGEMENT OF REMOVABLE DENTURES WITH FEW REMAINING TEETH
Authors: Arifianti Isti , Nabiila Suharto Alyaa
Published: February 2024

Tooth loss is the most common cause of decreased masticatory function. Losing teeth can also affect the oral cavity and general health, affecting a person's overall quality of life. Various things can cause tooth loss. The most common cause of tooth loss is poor oral health, especially caries and periodontal disease. Dentures can be made for patients who have lost all their teeth or have some remaining teeth. Retaining the remaining natural teeth can inhibit the alveolar bone resorption process and maintain bone height, thereby increasing the retention and stability of the denture. A 60-year-old female patient complained that many teeth were missing due to upper and lower jaw extraction, making it uncomfortable when eating and talking. The upper jaw has teeth 11, 21, 22, and 23 remaining, and the lower jaw still has 43 remain. The patient will have a removable denture with teeth 11, 23, and 43 as supporting teeth. The presence of a tooth can prevent alveolar bone resorption, especially if there is an occlusion load directly on the alveolar bone in edentulous cases. Natural teeth as supports can slow alveolar bone resorption and maintain retention and stabilization of dentures.
DENTIGEROUS CYST IN CHILDREN: A RARE CASE REPORT
Authors: Meliawaty Florence
Published: February 2024

Dentigerous cysts are growths of the jaw's epithelial lining that develop from the dental follicle of unerupted teeth. These cysts are usually found during routine radiography exams, associated with immature teeth. Dentigerous cysts typically don't cause symptoms unless they get big enough to swell. Third, molars and maxillary canines are frequently associated with most dentigerous cysts. A diagnosis is made based on histopathological, radiological, and clinical findings. We describe an instance of a dentigerous cyst that was connected to two immature mandibular premolar teeth. This rare case report discusses the treatment of a dentigerous cyst in the lower premolar region of the left mandible. Under local anesthesia, the patient had surgical treatment that included the removal of two primary teeth and enucleation of the cyst. The evaluation revealed that one week after surgery, the recovery was complete.

Authors: Zhang Yu , Ge Wei
Published: February 2024

According to relevant data from the China Child Development Report, the use of mobile phones by children has become a common phenomenon. Many adolescents are addicted to the pleasure of mobile phones, which leads to addiction. Previous studies have focused on exploring the reasons for children's mobile phone addiction but rarely focused on how to control and correctly guide children to use mobile phones. But there will be new inequalities in how different parents control their children's mobile phone use. This question is important for understanding and bridging the digital divide among children. This paper attempts to clarify the important influence of parents on solving the problem of children's mobile phone addiction through interviews. It finds out that different types of parents have different effects on reducing digital inequality in the process of children's digital detox. It also called on families and society to pay more attention to the problem of mobile phone addiction among children and make concrete efforts to carry out digital detox to reduce inequality.

Diabetes mellitus (DM) represents a significant lifestyle disease. Of the types of DM, type 2 DM aids maximum in the development of cardiovascular disease (CVD) along with diabetic cardiomyopathy (DbCM), which is correlated with significant mortality along with comorbidity in diabetic patients. DbCM is a non-canonical cardiac illness that exhibits cardiac remodelling occurs when there is DM but not when there is any concomitant conditions like hypertension, valve disease, or coronary artery disease (CAD). DbCM is linked to altered mitochondrial structure and function, as well as aberrant cardiac metabolism. Additional physiological and pathological signaling mechanisms include inflammation, oxidative stress (OS), and others; besides, in the diabetic environment, there are various cardiomyopathy-inducing factors such as reactive oxygen species (ROS)-modulated OS, hyperglycemic situations, cytokines-modulated These mediators induce inflammatory responses, cell death, including apoptosis, pyroptosis, and autophagy, as well as the epigenetic control of abnormal molecular pathways. The last 10-years have demonstrated the importance of miRNAs and long non-coding RNAs (lncRNAs) in controlling key biological processes such cell death, mitochondrial dysfunction, and electrical remodelling. Cardiomyopathy is a significant event regarding cardiac remodeling event in DbCM. Considerable proof exists regarding the part of epigenetics in diabetic correlated cell demise. Epigenetic controlling modes like histone alterations, DNA methylation, and miRNA along with lncRNAs control cardiac cell demise in the diabetic environment. Akin to that, other modes such as mitochondrial impairment and OS are controlled by miRNA along with lncRNAs. Finding these modes has given provision of generation of innovative therapy approaches for DbCM. miRNAs along with lncRNAs have illustrated translational capacity in the form of Besides treatment options, There are other DbCM-specific diagnostic and prognostic biomarkers available. HDACs were further shown to have a crucial role in controlling the pathogenesis of DbCM.
FEMALE LEADERSHIP AND INTRA-ENTREPRENEURSHIP: DIFFICULTIES, CHALLENGES AND BARRIERS FACED BY WOMEN IN ORGANIZATIONS
Authors: Gomes Larissa Moreli , De Barros Neto João Pinheiro
Published: February 2024

In all contemporary industrialized societies, women remain under-represented in meeting rooms and governments. While this gender gap has narrowed, the challenges women face in climbing the corporate and political ladder remain substantial. A male bias in the highest positions of leadership is universal. In fact, in most societies — both past and contemporary — formal political leadership positions were, and continue to be, almost exclusively occupied by men. If today women are not formally forbidden from holding leadership and entrepreneurial positions, they are still fewer or less powerful than their male counterparts. It is difficult to justify the fact that women are less likely to reach the highest echelons in politics, business, science and religion, given that there is no consistent evidence that they are leaders or entrepreneurs worse or better than men by virtue of their female characteristics. Attempting to explain the gender gap in leadership and entrepreneurship involves considering gender stereotypes, prejudice, institutional sexism, etc. This study sought to investigate this gender gap in an exploratory manner, through a literature review and interviews with women in the interentrepreneurship.

Published: February 2024

У статті охарактеризовано сучасний стан і тенденції в організації підприємництва в Україні, проаналізовано та виокремлено ефективні інструменти підтримки українського бізнесу Європейським Союзом з метою окреслення перспектив та викликів майбутньої співпраці в умовах статусу кандидата в члени ЄС. Зокрема, проаналізовано обсяги, динаміку та основні інструменти підтримки українського бізнесу Європейським Союзом за останні роки, зокрема, в умовах ризиків, пов’язаних з військовими діями в Україні. Акцентовано, що всупереч тенденції до 30% падіння економіки, спричиненого людськими та матеріальними втратами, порушенням нормальних умов торгівлі та втратою основних зовнішньоторговельних партнерів, МСП, які отримують підтримку "EU4Business", звітують про зростання обороту на 18%. Це свідчить про те, що результати допомоги "EU4Business" у 2022 році та попередні роки створили платформу стійкості, яка допомогла українським МСП пережити перший рік війни: це, безсумнівно, продовжилося і в 2023 році, що сприятиме подальшому відновленню. Встановлено, що Європейський Союз – один з найпотужніших системних донорів України протягом багатьох років – від початку повномасштабної російської війни сконцентрував ресурси на підтримці саме малого і середнього бізнесу. Гранти для МСП, консультації, підтримка підприємств, релокованих з регіонів бойових дій, зняття торговельних квот на експорт, допомога у пошуку нових ринків і партнерств – ключові вектори програм з допомоги українському бізнесу, яку надає Євросоюз. Представлено окремі узагальнення щодо настроїв, очікувань та прогнозних показників українського бізнесу під час війни. Визначено основні напрями ініціатив ЄС, що мають на меті допомогу українським підприємцям у знаходженні нових ділових партнерів в ЄС та виходу на нові ринки. Це забезпечить можливість надання різних форм підтримки бізнесу та дозволить Україні брати участь у розширеному партнерстві, спрямованому на розробку нової європейської статистики з використанням багатьох джерел даних, передових методів аналізу даних, смарт систем і цифрових технологій.

Thermodynamic properties and moisture sorption isotherms of Artemisia herba-alba
Authors: Lamharrar Abdelkader , Idlimam Ali , Kouhila Mounir
Published: February 2024

Sorption isotherms of Artemisia herba-alba were determined at three temperatures (30, 40 and 50 °C) and in the range of water activity varying from 0.0572 to 0.898. The hysteresis effect was distinctly observed in the range of temperature tested. Five sorption models were used to fit the experimental data. The GAB equation was the best model describing the equilibrium moisture data for desorption. The modified Halsey equation was the most suitable model for describing adsorption isotherms. Thermodynamic properties such as differential enthalpy and entropy were determined from moisture sorption data, using the Clausius-Clapeyron equation. The experimental data showed that enthalpy-entropy compensation theory was applicable for the moisture sorption behaviour of Artemisia herba-alba.

Le dioxyde d’étain est un matériau largement utilisé dans différents domaines d’applications électroniques et optiques, notamment, dans la conception des cellules photovoltaïques nanocristallines à base de colorant qui est notre objectif. Cet article présente l’élaboration des couches minces de dioxyde d’étain par recuit sous oxygène de couches minces d’étain obtenues par évaporation sous vide. Cette méthode consiste à évaporer sous vide des couches d’étain sur des substrats en verre ordinaire. Dans un premier temps, nous avons remarqué que l’épaisseur de la couche d’étain ainsi que le temps de recuit influe sur la cristallinité de la couche de SnO2. Ainsi, un recuit effectué à 300 °C sous oxygène laisse la couche amorphe. Le SnO2 est obtenu pour un recuit de 2 heures à 500 °C d’une couche de 1000 Å d’étain. C’est pour cette raison que nous choisissons des couches d’épaisseur 1000 Å et des températures de recuit de 500 °C. Dans ces conditions et sous flux d’oxygène, on obtient la cristallisation du Sn en SnO2 de structure tétragonale. L’analyse par diffraction de rayons X permet de déterminer la nature des phases formées. Le film d’étain formé par évaporation sous vide est cristallin il est de structure tétragonale composé de grains de différentes tailles séparés par des joints de grains. A 500 °C et pour une durée de recuit de deux heures le dioxyde d’étain (SnO2) de structure tétragonal apparaît et augmente en quantité lorsque le temps de recuit augmente et cela jusqu’à dix heures. Les différentes techniques d’analyse utilisées telles que la Microscopie électronique environnementales, l’analyse EDX et DRX se complètent pour confirmer les résultats obtenus.

Le but de ce travail est d’étudier l’interaction d’une couche limite avec deux cavités et de caractériser la structure dynamique de l’écoulement. Pour le cas d’une seule cavité large, la structure assure l’existence d’une grosse recirculation où il y a la naissance de deux tourbillons; une petite au pied de la première marche et l’autre plus grande qui couvre toute la cavité avant de s’échapper après recollement. Ce phénomène a été bloqué, dans le deuxième cas, par l’existence de l’obstacle et la création d’une nouvelle cavité. L’étude des profils des vitesses, dans les différentes sections du domaine, montre que le profil d’entrée n’est plus laminaire.

Dans ce papier, nous analysons la conception et le fonctionnement dans l’environnement Orcad-Pspice d’un système photovoltaïque adapté par une commande MPPT analogique. Nous proposons l’amélioration du fonctionnement d’un système photovoltaïque suite aux brusques variations des conditions météorologiques et la charge. Ceci est obtenu par l’association d’un circuit de détection de dysfonctionnement et de changement de sens ‘CDCS’ conçu au cours de ce travail. Le rôle de ce circuit ‘CDCS’ est de détecter un éventuel dysfonctionnement du système ‘PV’ puis converger le système vers les conditions optimales sans redémarrer le système photovoltaïque.
The enhanced cooling of heated blocks mounted on the wall of a plane channel filled with a porous medium

Published: February 2024

This is a two dimensional numerical simulation of the laminar air forced convection cooling of six blocks mounted on the lower wall of a plane horizontal channel filled (or not filled) with a porous medium. The blocks are equally spaced and heated by a uniform volumetric heat generation. The objective of the study is the determination of the enhanced cooling of the blocks when the channel is filled with a porous medium. The problem is modelled by the continuity, momenta and energy equations with their appropriate initial and boundary conditions. When the channel is filled with a porous medium, a Darcy-Forchheimer-Brinkman flow model is used to describe the flow field. The model equations are numerically solved by a second order accurate finite volume method. The results show that the flow field of the channel filled with a porous medium is very different from that of the channel without the porous matter. A major difference is the appearance of circulating vortices between the blocks when the porous matter is inexistent. This flow pattern difference favours a convective heat transfer enhancement of the flow in the channel filled with the porous matter. Moreover, the effective thermal conductivity of the considered porous medium is higher than that of the fluid. These two factors lead to a considerably better cooling of the blocks mounted in the channel filled with the porous matter. Thus, the use of porous media when possible is recommended because it enhances the cooling of heated blocks mounted in channels.
