Published: August 2023

A necessidade de serviços em nuvem vem aumentando nos últimos anos, onde usuários da Internet passaram a consumir cada vez mais serviços hospedados na nuvem. Portanto, observa-se a necessidade crescente por recursos computacionais que precisam ser ofertados. Adotar a computação em nuvem com um sistema de arquivos para fornecer dinamicamente recursos é uma das possíveis soluções para esse problema. No entanto, o grande aumento na utilização desse tipo de serviço pode gerar experiências negativas para os usuários caso os recursos necessários não tenham um desempenho satisfatório. Portanto, esse trabalho realiza uma análise de desempenho de um sistema de arquivos, o Nextcloud, hospedado em uma nuvem privada. Os resultados do modelo demonstram que a medida que usuários entram no sistema, o tempo de atendimento aumenta consideravelmente. O tempo médio de espera parte de um pouco mais de 2 minutos para um cenário de 100 usuários pra mais de 12 minutos considerando um cenário de 500 usuários.

Authors: Monteiro Felipe C. , Brito Felipe T. , Chaves Iago C. , Machado Javam C.
Published: August 2023

Dados de tráfego de redes são úteis para uma variedade de aplicações. Geralmente as entidades que coletam esse tipo de dado, por exemplo provedores de internet (ISPs), compartilham suas informações de tráfego de rede com entidades externas. Contudo, esse compartilhamento pode levar a violações de privacidade dos indivíduos contidos nesses dados. Este trabalho propõe uma nova abordagem para compartilhamento de dados de tráfego de rede utilizando privacidade diferencial, um método que tem como objetivo adicionar ruído sobre os dados originais. Resultados experimentais mostram que a abordagem proposta introduz menos ruído nos dados quando comparada a outras técnicas que também adotam privacidade diferencial.

Transnational Insights for Climate Litigation at the European Court of Human Rights: A South-North Perspective in Pursuit of Climate Justice
Authors: Murcott Melanie , Tigre Maria Antonia , Zimmermann Nesa
Published: August 2023

The global climate crisis is increasingly recognised as an issue of climate injustice, including because it is causing (and worsening) inequalities and human rights violations. Moreover, responsibility for emissions and vulnerability to climate impacts are not evenly distributed. They vary among and within states. In order to tackle these issues of justice both within and among states, litigants have taken to domestic and regional courts to engage in climate litigation. A body of transnational climate jurisprudence is emerging in which courts are increasingly looking to laws beyond their relevant state or region, engaging with the moral aims of human rights law, and solidifying international climate commitments. In adjudicating climate cases, courts have become important sites of climate justice. The European Court of Human Rights (ECtHR) is currently adjudicating several important climate cases and could become a key player in responding to the climate crisis. From the point of departure that in a time of climate crisis courts have a crucial role to play in advancing climate justice, we conceptualise climate (in)justice and its significance in climate adjudication. Then, we examine how, in addressing questions of standing and transboundary harm, looking beyond the European Convention on Human Rights legal regime to the Global South (South Africa and the Inter-American System of Human Rights, respectively) could offer valuable transnational insights as the ECtHR adjudicates climate cases. In doing so we hope to contribute to the ongoing transnationalisation of climate jurisprudence.
A Practical Approach to the Diagnosis of Lymphedema: a Narrative Review
Authors: Banner Lauren , Cohen Alexa , Patel Viral , Nikbakht Neda
Published: August 2023

Introduction: Lymphedema often presents as progressive, unremitting swelling and skin changes that are extremely distressing to patients. Hereditary lymphedema (HL) constitutes a type of primary lymphedema that is passed down through generations.
Objectives: The primary aims of this narrative review are to illustrate a framework to distinguish lymphedema from other causes of swelling and to differentiate the hereditary lymphedemas from each other.
Results: A literature search was undertaken using relevant search terms. The articles were evaluated to generate a diagnostic algorithm to approach the swelling of an extremity using clinical and laboratory data. First, the stemmer sign should be evaluated. If it is negative, other causes should be considered. History and additional physical exam findings suggest either a primary or secondary cause of lymphedema.
Conclusions: The hereditary lymphedemas have been classified by age of onset and then stratified by clinical criteria and genetic testing.

Authors: Mohamed Noha E , Soltan Mohamed R , Galal Sara A , El Sayed Hassan Salem , Hassan Hadir  M , Khatery Basma HM
Published: August 2023

Introduction: Female Pattern Hair Loss (FPHL) is considered the most common type of hair loss in females. Women with FPHL may suffer from psychological distress and defective social functioning. Patients with psychiatric and neurodegenerative disorders almost have a deficient brain and blood brain-derived neurotrophic factor levels (BDNF). This serum BDNF level may act as a diagnostic marker for negative psychological impact in FPHL patients.
Objectives: Evaluate the levels of serum BDNF in patients with FPHL and correlate its level to the severity of alopecia and the degree of psychological impact.
Methods:  Forty-six female patients with FPHL and 41 healthy age-matched female volunteers as a control were included in the study. Patients filled out a Dermatology Life Quality Index questionnaire. Both patients and controls filled Beck Depression Inventory, Beck Anxiety Inventory, and Perceived Stress Scale (PSS) questionnaires. Serum levels of BDNF were measured for all the participants using the ELISA technique.
Results: Patients with FPHL had significantly lower levels of BDNF and significantly higher Beck depression inventory score and PSS questionnaire scores. There is a significant negative correlation between serum levels of BDNF and Beck Depression Inventory, Beck Anxiety Inventory, and PSS questionnaire scores.
Conclusions: Patients with FPHL are at a high risk to develop chronic stress and depression. The serum level of BDNF is a good predictor for the assessment of chronic stress and depression in FPHL patients.

Authors: Kaya Özge , Keskinkaya Zeynep , Işık Mermutlu Selda , Oğuz Kılıç Sevilay , Öztürk Sevgi
Published: August 2023

Introduction: Based on the existing literature, omalizumab (OMZ) is considered a safe treatment modality in chronic spontaneous urticaria (CSU) during the coronavirus disease 19 (COVID-19) era. 
Objectives: The aim of this study is to evaluate the effects of OMZ on CSU patients regarding COVID-19 infection.
Methods: In this retrospective study, files of CSU patients using OMZ during the COVID-19 pandemic were reviewed in terms of demographic features, medical history including COVID-19 vaccination status, clinical characteristics, pretreatment laboratory parameters, duration, and dosing regimen of OMZ treatment. Patients with a history of COVID-19 infection while on OMZ therapy and patients without COVID-19 history were compared with respect to these parameters. The urticaria activations following COVID-19 infection or vaccination were also recorded.
Results: Sixty-eight patients with CSU (female:male ratio= 1.8:1; mean age=  47.2 ± 15.1 years) continued to receive OMZ treatment. The median duration of OMZ treatment was 12 months (range: 6-60). Twelve patients (17.6%) were diagnosed with COVID-19 showing no exacerbation in urticaria. The duration of OMZ treatment was significantly higher in the group with COVID-19 infection history compared to patients with no history of COVID-19 (p=0.01). Among 51 patients (75%) vaccinated against COVID-19, urticaria activation occurred in four patients without any recurrence following booster vaccinations.
Conclusions: Considering the likelihood of increased COVID-19 infection risk in the setting of long-term OMZ in CSU patients, the duration of OMZ therapy might be kept at a minimum, or a temporary interruption of the treatment period might be preferred, particularly in high-risk patients regarding COVID-19.

Authors: Camela Elisa , Villani Alessia , Ocampo Garza Sonia Sofia , Costa Claudia , Fabbrocini Gabriella , Megna Matteo , Potestio Luca , Ruggiero Angelo , Scalvenzi Massimiliano
Published: August 2023

Introduction: Dysgeusia may occur during conventional or target-therapies and affect patients adherence-to-treatment. Therefore, it should be monitored to improve clinical outcome. To date, available questionnaires on dysgeusia relate to traditional antineoplastics and do not apply to target-therapies as the pathogenetic mechanism and clinical expression differ.
Objectives: To develop a patient-reported outcome measure (PROM) to screen for and monitor the occurrence and severity of dysgeusia in patients under Smoothened (SMO) inhibitors: the SMO-iD questionnaire.
Methods: Patients with locally advanced basal cell carcinomas referring dysgeusia under SMO inhibitors at the University Hospital of Naples Federico II, were enrolled between January-December 2020. The PROM was elaborated based on chemotherapy-induced dysgeusia (CiTas) scale (development phase) and then validated by measuring internal consistency and reliability (validation phase).
Results: Thirty-nine patients were enrolled and interviewed every 8 weeks. In the first phase, 160 CiTas questionnaires were collected, and the SMO-iD questionnaire was developed. In the second phase, 195 SMO-iD questionnaires were recorded, and reliability and validity assessed. Cronbach alpha was 0.89.
Conclusions: The SMO-iD questionnaire is a validated questionnaire that shows high face and content validity as well as high internal consistency and reliability. Hence, it may be introduced in daily clinical setting to monitor dysgeusia in patients under SMO-inhibitors.

Authors: Youssef Randa , Emad Nourhan , Mogawer Rania M
Published: August 2023

Introduction: There are diverse assessment tools for vitiligo, with no standardized approach that helps unify treatment outcome measures. Thus, comparing different treatment modalities and developing evidence-based recommendations for vitiligo management has been quite challenging.
Objectives: We compared the most commonly used tools assessing both vitiligo activity and extent, namely, Vitiligo Disease Activity Score (VIDA) and Vitiligo Area and Severity Index (VASI) score to their newly developed counterparts, namely, Vitiligo Extent Score Plus score (VES plus) and Vitiligo Signs of Activity score (VSAS), to provide insights that would help set recommendations for a unified outcome assessment protocol for vitiligo patients.
Methods: Thirty-six active non-segmental vitiligo cases were recruited, 30 of whom  completed 48 sessions of narrow band ultraviolet B (NB-UVB). Patients were assessed for both extent and activity both before and after treatment with NB-UVB. Scores were correlated. Additionally, VES plus was assessed for its reliability in comparison to VASI score.
Results: Both extent (VASI and VES plus) and activity scores (VIDA and VSAS) showed significant improvement following treatment. Additionally, VES plus and VASI were positively correlating both before and after treatment as well as their percent change. Furthermore, VES plus proved as reliable as VASI. Regarding activity scores, total, hypochromic and Koebner VSAS only correlated with VIDA following treatment. Confetti VSAS neither correlated with VIDA before nor after treatment.
Conclusions: VES plus and VASI scores have proven of comparable reliability. While examination-based VSAS score comes as an additive tool to the history-based VIDA score.

Mathematics is a universal science that will continue to develop along with the times, a science that is obtained carefully, clearly, and accurately. Learning and understanding math is difficult, complicated and scary because it requires students to think logically, carefully, diligently, systematically, and must have learning motivation. Learning motivation is a description that is often used to explain the success of students' learning tasks, the time and effort they devote to them, so that the desired learning goals are achieved. The higher the child's motivation, the higher the learning outcomes obtained by students. To increase students' motivation and learning outcomes in this study using the Student Teams Achievement Division (STAD) cooperative type. The purpose of this study was to determine the learning motivation and mathematics learning outcomes of students in classes that used Student Teams Achievement Division (STAD) cooperative type. The population in this study was the learning motivation and mathematics learning outcomes of grade XI students of MA Negri 1 Indramayu. The sample was selected randomly. The instruments used were a test of description questions and observation sheets of student motivation. The results of data processing obtained the average in cycle 1 for learning outcomes is 78.75 and the average motivation in cycle 1 is 2.86 with a sufficient category of 19 students and a less category of 7 students. The results of data processing in cycle 2 obtained an average for learning outcomes of 80.00 and an average motivation in cycle 2 of 3.36 with a sufficient category of 23 students and a good category of 3 students. And the results of data processing in cycle 3 obtained an average for learning outcomes of 86.92 and an average motivation in cycle 3 of 3.86 with a good category of 25 students and a very good category of 1 student. So it can be concluded that cooperative learning type Student Teams Achievement Division (STAD) can increase students' motivation and math learning outcomes. For further research, other methods can be developed to improve student learning outcomes.
Leonardo da Vinci’s Aphorism on the Aristotle-Alexander Legend: Sources, Meaning, And Its Reception by Francis Bacon
Authors: Demetracopoulos John A. ,   University of South Bohemia
Published: August 2023

One of Leonardo da Vinci’s autographed aphorisms states that Aristotle and Alexander were each other’s teachers. Interpreting it in light of those of Leonardo’s readings which instigated him to write it down along with providing him the material he needed to do so, I argue that the aphorism turns against Aristotle as an emblematically boastful, know-it-all man involved in undue occupation of all knowledge throughout history. Leonardo presents Aristotle as if he had been taught by the pernicious conqueror Alexander to act in scholarship in the way the Macedonian king had acted in politics and external affairs. The core of this critique goes back to a traditional anti-Aristotelian point in Antiquity, complies with the 15th- and 16th-century anti-Aristotelianism and goes hand-in-hand with Leonardo’s own view that intelligent men (including himself) are capable of going much further than Aristotle in the direction of discovering the truth. I identify Leonardo’s sources and I argue that Francis Bacon’s repeated bitter remark that the soul of Aristotle was infected by Alexander’s tyrannic character was quite probably based on Leonardo’s aphorism.

Estimating the Compressive Strength of Self-compacting Concrete with fiber using an Extreme Gradient Boosting model
Authors: Prakash Indra , Phan Thanh-Nhan , Mai Hai-Van Thi
Published: August 2023

Self-compacting concrete reinforced with fiber (SCCRF) is extensively utilized in the construction and transportation industries due to its numerous advantages, such as ease of building in challenging sites, noise reduction, enhanced tensile strength, bending strength, and decreased structural cracking. Traditional methods for assessing the compressive strength of SCCRF are generally time-consuming and expensive, necessitating the development of a model to forecast compressive strength. This research aimed to predict the CS of SCCRF using the Extreme Gradient Boosting (XGB) machine learning technique. The research uses the grid search method to optimize the XGB model's hyperparameters. A database of 387 samples is collected in this work, which is also the most enormous dataset compared to those utilized in previous studies. An excellent result (R2 max = 0.97798 for the testing dataset) proves that the proposed XGB model has very good predictive power. Finally, a sensitivity analysis using Shapley Additive exPlanations (SHAP values) is conducted to understand the effect of each input variable on the predicted CS of SCCRF. The results show that the age of samples and cement content is the most critical factor affecting the CS. As a result, the proposed XGB model is a valuable tool for helping materials engineers have the right orientation in the design of SCCRF components to achieve the required compressive strength.

Metaheuristics are popular and effective techniques for solving such problems. This paper introduces the application of the standard Particle Swarm Optimization (PSO) algorithm with discrete integer variables to solve the problem of optimizing the position of tower cranes and material supply points. A calculation program was built and numerical tests with 2 scenarios was conducted. The results show the performance of PSO and the applicability of the algorithm in the class of technical problems similar to the one under consideration.

This paper is aimed to apply hybrid machine learning model namely GA-ANFIS, which is a combination of Adaptive Neuro-Fuzzy Inference System (ANFIS) and Genetic Algorithm (GA), for the prediction of total bearing capability of driven piles. A database of 95 Pile Driving Analyzer (PDA) tests carried out at the win power project in Hoa Binh province, Vietnam was used to develop hybrid model. The database was split into 70:30 ratio for training (70%) and validating (30%) model. Accuracy of the model was evaluated using statistical standard indicators: Coefficient of determination (R2), Mean Absolute Error (MAE), and Root mean squared error (RMSE). Results indicated that the GA-ANFIS model has a good performance in correct prediction of the total bearding capability of driven piles on both training (R2 = 0.976) and testing (R2 =0.925) datasets. Therefore, the GA-ANFIS hybrid model is a promising tool for quick and accurate prediction of the total bearing capability of driven piles for the consideration in design and construction of the structures.

Background: Breast Cancer is the most common malignancy among the Iraqi population; the majority of cases are still diagnosed at advanced stages with poor prospects of cure. Early detection through promoting public awareness is one of the promising tools in its control. Objectives: To evaluate the baseline needs for breast cancer awareness in Iraq through exploring level of knowledge, beliefs and behavior towards the disease and highlighting barriers to screening among a sample of Iraqi women complaining of breast cancer. Methodology: Two-hundred samples were enrolled in this study; gathered from the National Cancer Research Center of Baghdad University and the Oncology Teaching Hospital of the Medical City throughout the year 2015. The study population comprised two groups: the first included 100 female patients who were receiving treatment for breast cancer (Group A), while another 100 randomly selected apparently healthy women served as Control (Group B). Those were asked to complete a structured questionnaire which was designed to explore the level of knowledge, beliefs, behavior towards breast cancer and the barriers to early diagnosis. The studied variables included the socio demographic and clinical data, women needs and beliefs regarding breast health and cancer care, and the barriers to screening. Results: Ninety percent of patients with breast cancer in Group I recorded a minimum score of Good; they have answered confidently that the disease is common among women, can be curable when detected at early stages and is not contagious. They also display a significantly higher attitude regarding performing BSE, receiving routine CBE check up and having the courage to be informed about the diagnosis of cancer. Although both groups believe that early detection of cancer should be promoted culturally, Group I displayed a stronger reaction to place this approach as a priority in the community. Overall, both groups do not believe that the disease is usually fatal, could bring disgrace to the family leading to divorce, and did not consider mammography as an embarrassing procedure against religious beliefs. Nevertheless, the majority refuse to be examined by a male doctor and to undergo screening mammography if they have no complaints. Recommendations: Feasible strategies should be more promptly adopted to overcome barriers to early detection of breast cancer among the Iraqi patients; focusing on promoting public health education and ensuring the availability of accessible well equipped diagnostic facilities.

Existence of solutions for critical fractional p-Laplacian equations with indefinite weights
Authors: Cui Na , Sun Hong-Rui
Published: August 2023

This article concerns the critical fractional p-Laplacian equation with indefinite weights $$ (-\Delta_p)^su=\lambda g(x)|u|^{p-2}u+h(x)|u|^{p_s^*-2}u \quad \text{in }\mathbb{R}^N, $$ where \(0<s<1
sp\) and \(p_s^*=Np/(N-sp)\), the weight functions \(g\) may be indefinite, and \(h\) changes sign. Specifically, based on the results of asymptotic estimates for an extremal in the fractional Sobolev inequality and the discrete spectrum of fractional p-Laplacian operator, we establish an existence criterion for a nontrivial solution to this problem.
