Influences of Structural and Friction Parameters on Transformation of Contact State in Friction-Induced Vibration
Authors: Wang Peng , Yu Zhenliang , Deng Yongsheng , Luo Haitao , Wu Nan 
Published: December 2022

Abstract
To investigate the effects of friction operation conditions and vibration system parameters on the friction states transformation during vibration, the friction-induced vibration (FIV) mathematical model of a single-degree-of-freedom (SDOF) system in the direction of friction is introduced. The vibration response is solved by an iterative method combining kinematics and vibrology. The velocity and direction changes of the friction force caused by the sliding of the moving plate on top of the mass will lead to the ‘rebound’ phenomenon and the transformation of contact states. Numerical simulation and parameter studies were used to investigate the effects of stiffness constant, mass, normal force, velocity, damping ratio, and friction coefficient on the conversion of friction state, vibration response, and friction history. The numerical results show that the time of mass block and plate staying on stick status increases with normal force, static friction coefficient, the delay rate of relative sliding velocity control coefficient, and decreases with the increment of stiffness, velocity, mass, the lower limit of static friction coefficient and damping ratio. In the absence of general quantitative definitions and conclusions, the trend of this paper is to show the change of friction state during FIV through an accurate physical system.

Published: December 2022

Abstract
The aim of this paper is to characterize some equations of structures for gradient almost η-Ricci Bourguignon solitons which generalize the equivalent for gradient η-Ricci-Bourguignon solitons. We prove that a gradient almost η-Ricci-Bourguignon soliton is gradient almost 1/ωu-traceless Ricci soliton with a well defined potential function f. Moreover we investigate that an Einstein manifold of constant scalar curvature is isometric to a space form with a well defined potential function f. Finally, we derived an integral formula for gradient compact case. We show that a compact nontrivial almost 1/ωu-traceless Ricci soliton with constant scalar curvature or conformal potential vector field, is isometric to a standard unit sphere, hyperbolic space and Euclidean space.
Theory of Machine Learning with Limited Data
Authors: Sapir Marina 
Published: December 2022

Abstract
Application of machine learning may be understood as deriving new knowledge for practical use through explaining accumulated observations, training set. Peirce used the term \textbf{abduction} for this kind of inference. Here I formalize the concept of abduction for real valued hypotheses, and show that 14 of the most popular textbook ML learners (every learner I tested), covering classification, regression and clustering, implement this concept of abduction inference. The approach is proposed as an alternative to Statistical learning theory, which requires an impractical assumption of indefinitely increasing training set for its justification.
Improved database security using cryptography with genetic operators

Published: December 2022

Abstract
Data integrity, confidentiality and authenticity, are the most valuable resources in today's digital world. As technology advances and data are being exchanged via the internet, several measures are being created to prevent unauthorised access to data. Various security models have been developed for databases, each concentrating on a different part of the database security challenge or exploring alternative conclusions about what defines a secure database. Database security refers to the measures that protect the database from intentional or unintentional risks, unauthorised users, hackers, and IP snoopers. Because the organisation requires the safety of the data in the database, a security method to protect the database is required. This paper proposes a hybrid concept known as cryptography with a genetic algorithm to provide greater security for the database. The encryption part uses a genetic algorithm along with the default authentication, which has a user id and password for the database. The database securely encrypts data in every field, stored in encrypted form. Therefore, when accessing encrypted data, the database asks for the key value to decrypt the data. So this acts as dual protection for the database, which makes the proposed technique more secure than the traditional technique. Deleting and updating the records can be done, creating new records or even database operations.

Published: December 2022

Abstract
The accurate measurement of acid concentration, including hydrogen chloride (HCl) and ferrous chloride concentrations (FeCl2), is a critical part of ensuring the quality of strip steel pickling. In this study, a multi-task attention convolutional long short-term memory (MACL) neural network model was proposed to predict hydrogen ion and ferrous ion concentrations simultaneously. Firstly, in order to extract significant information from the input sequence, an attention mechanism was added to the model to calculate the correlation between the input features and the acid concentration at each time step. Next, multi-task learning explores the connections between the two tasks and exploits hidden constraints to improve prediction accuracy. Finally, deep features were extracted through convolutional long short-term memory (CLSTM) neural network, and the acid concentration was predicted. The proposed MACL model was compared with other popular prediction models. The experimental results show that proposed MACL model generally outperforms other models, indicating that proposed model has excellent predictive performance and effectiveness.

Published: December 2022

Abstract
In this article, we propose a new empirical screen for detecting cartels, using the cointegration as our basis of modeling. The proposed screen is capable of identifying potential cartel behavior, indicating the strength of price adjustment among firms, and providing a basis for assessing structural change. An initial demonstration of the screen on the Turkish cement market yielded promising results and the framework may benefit other field competition experts to unveil concrete statistical evidence and establish reasonable doubt in their investigations of cartel-like formations.

Published: December 2022

Abstract
Background
Acute febrile diseases transmitted by mosquitos are a diagnostic challenge for pediatricians working Sub-Sahara-Africa. Misclassification due to the lack of rapid, reliable diagnostic tests leads to the overuse of antibiotics and antimalarials.
Methods
Between April 2016 and March 2018, 751 children presenting with acute fever and suspected of having malaria were examined at healthcare facilities located in Mwanza Region, Tanzania. Sociodemographic data and medical histories were obtained. The sensitivity and specificity of blood smear microscopy and malaria rapid diagnostic tests were compared to multiplex-RT-PCR-ELISA.
Results
One hundred thirty-seven of 698 (19.6%) pediatric patients meeting the inclusion criteria and presenting with acute fever had Plasmodium falciparum infections confirmed by PCR. 22,8% received antibiotics and 22,6% antimalarials prior to admission. No evidence of arboviral infections was found. Blood smear microscopy exhibited 33.3% sensitivity and 93.2% specificity. Malaria Rapid Test NADAL® provided 86.6% sensitivity and 98.2% specificity in detecting acute malaria infections. Only 7.2% of malaria-negative children received antimalarials at Sengerema Designated District Hospital when treatment was guided by the results of the rapid test.
Conclusions
Misclassification and premedication of non-malarial, febrile illnesses contribute to the emergence of antimalarial and antimicrobial resistance. Rapid, reliable diagnostic tests could reduce the number of antimalarial prescription significantly. This occurred when Malaria Rapid Tests were incorporated into the clinical routine and the results were translated into adequate treatment.

Published: December 2022

Introduction. Melanoma is one of the most deadly human skin tumors, and surgery remains the first and main method in its combined treatment. Despite the seemingly radical nature of surgical interventions in patients with primary skin melanoma, the frequency of locoregional recurrence and metastasis remains high.Objective. To analyze the effect on the survival rate of the use of plastic methods to close the surgical tissue defect in patients with primary melanoma of the skin after tumor removal in comparison with patients in whom plastic surgery was not used.Materials and methods. The study used data from 337 patients with stage 0-IIIc primary skin melanoma, randomized into 2 groups: the main group (with the use of plastic closure of a postoperative tissue defect) and the comparison group (with linear suturing of a tissue defect).Results. It was found that the use of plastic replacement of tissue defect in patients with localized forms of skin melanoma shows the best results of 5-year progression-free survival from 22 to 22.6% (p < 0.050), and at stage 0-IIa and in 5-year corrected overall survival rate up to 13.1% (p < 0.050).Conclusions. Performing plastic replacement of a tissue defect reduces wound edge tension and rough scarring, accelerates postoperative healing, may be an independent prognostic factor that improves progression-free survival and adjusted overall survival of patients with primary localized skin melanoma, and also be the method of choice among other methods.
Yanılsamanın Sahnesi Dünya ve Nietzsche’nin Araçsal Değer Analizi
Authors: KAHRAMAN Hilal 
Published: December 2022

Nietzsche insanlığın başlangıcından beri var olan, uzlaşılarla geliştirilen değerleri birer araç olarak görmektedir. Ona göre insanlar dünyanın gerçek doğasını görmekten korktukları için bu araçları geliştirmişlerdir. Dünyanın görünüşünün ardında var olan gerçek halini görmek ve aslında yaşadıkları dünyanın amaçsız ve anlamsız olduğunu teşhis etmek insanlar için kolay değildir. Bu yüzden derin düşünmeden, yüzeysel kalarak oluşturdukları ortalama değerler aracılığıyla rahatlamayı ve yaşamayı tercih ederler. Oluşturdukları değerler onlar için amaçlarını gerçekleştirme yolunda birer araçtır, aynı zamanda kendi davranışlarını meşru kılmak adına bu değerler üzerinde değişiklikler yapabilir, lehlerine kullanabilirler. Yaşadığı dönemde var olan bozulma ve sıkıntıların kaynağında bu değerlerin bulunduğunu düşünen Nietzsche, değerlerin odağında bulunan ve dönemin Alman ulusuna hâkim olan Hıristiyanlık ve Tanrı anlayışına eleştirilerde bulunmuştur. Giderek bozulduğunu iddia ettiği Hıristiyan inancı, özellikle katı Katolik mezhebinin düşüncesi, aynı zamanda kendi buhranları ve yaşantısı Nietzsche’nin dini sorgulayarak eleştirmesine neden olmuştur. Kilisenin toplumlara yönelik baskın bir role sahip olduğu bu dönemde Tanrının dünyadaki eli olduğu iddiasında olan ve Tanrı adına hareket eden din adamlarına karşı tepki gösteren Nietzsche, bir Tanrı varsa aşkın bir karakterde bulunması ve tüm insanlığa aynı mesafede olması gerektiği düşüncesindedir. Tanrı bu dönemde aynı zamanda büyük anlatılar için insanlığın kullandığı bir araçtır. Dünyada var olan kaos içinde nesnel bir düzen olduğuna inanan insan, Tanrı aracılığıyla evrende bir amaç ve anlam bulmaya çalışmaktadır. İnsanın çaba ve mücadelelerinin boşuna olmaması ve temellenebilmesi için evrendeki hareketin özüne yerleştirebileceği bir Tanrı düzeni, bununla beraber yaşamın kendisine dair bir ilerleme inancı ve bunların yanında bir amaç bulması gereklidir. Ancak insan ihtiyaç duyduğu ve açıklamalarının merkezine yerleştirdiği Tanrısına ihanet etmektedir ve Nietzsche’ye göre bu durum ise kilisedeki bozulmalara ek olarak dünyada da bozulmalara neden olmaktadır.
Bu çalışmada Nietzsche’nin aklın değil yanılsamaların sahnesi olduğunu iddia ettiği dünya ve üzerindeki bozulmaların kaynağına ilişkin düşünceleri analiz edilerek, geleceğe yönelik yeniden değerlendirilmesi gerektiğini ileri sürdüğü araçsal değerler ve yönelttiği eleştirilerini irdelemek amaçlanmaktadır.
Demokrat Parti Dönemi'nde Bira Sanayisi'nin Gelişimi (1950-1960)
Authors: GÜRDAMAR Ersin 
Published: December 2022

Bira üretimi ve tüketimi Osmanlı döneminde Anadolu topraklarında oldukça sınırlı kalmıştır. Düşük alkollü bir içki olan bira, arpa ve şerbetçi otu içermesi sebebiyle ziraat alanını da kapsamaktaydı. 1800'lü yıllar itibarı ile Avrupa'nın ekonomik ağları Osmanlı'nın biracılık sektörünü de kapsamaya başlamıştı. Cumhuriyet yönetimi katma değer üretme ve ziraat ile sanayinin buluştuğu alanları önemseme yolunda oldukça kararlıydı. Osmanlı döneminde geri kalmış olan bu alanda yatırımlar yapılması kaçınılmazdı. Atatürk Orman Çiftliği'nde 1934 yılında bir Bira Fabrikası açılmıştı. Üreten köylü aynı zamanda ürününü işleme fırsatına da sahip olmuştu. Bu yıllarda bira ihracatı tüm dünyada zordu. Bununla birlikte iç tüketim yerli imkanlarla karşılanmıştı. Birada 1940 yılına gelindiğinde tekel uygulaması başlamıştı. Böylece özel sektörün gelişmekte olan bir sanayisine yapabileceği olumsuz etkiler önlenmiş olacaktı.
1950 yılında iktidara gelen Demokrat Parti, Tekel Bakanlığı'nın elinde bulunan bira dahil bazı ürünleri devletin elinden tasfiye ederek özel sektöre açtı. Bununla birlikte bira sadece gelir getiren değil aynı zamanda tarımı geliştiren bir üründü. Ancak bira sektörünün özel sektöre açılması beklenen etkiyi yaratmadı. Büyük kârlar göremeyen yabancı sermaye Demokrat Parti döneminde biracılık alanında Türkiye'ye giriş yapmadı. Bu durumda mevcut iki fabrika kapasitesinin üstünde üretim yapmaya zorlandı. Demokrat Parti, iki fabrikanın üretim kapasitesini artırmaktan başka bir politika uygulayamadı. Yozgat'ta kurulması planlanan yeni fabrika ise uygulamaya geçirilemedi. Bu çalışmanın amacı liberal politika ilkesiyle yola çıkmış olan Demokrat Parti'nin bira örneğinde ortaya koyduğu ekonomi performansını detaylandırmaktır. Bu çalışma TBMM zabıt cerideleri, arşiv belgeleri, resmî gazete, kongre tutanakları, ilgili mevzuat ve dönemin süreli yayınlarına dayandırılmaktadır.
Vitamin D deficiency in patients with diabetes and its correlation with water fluoride levels
Authors: Kumar Pramod , Gupta Rasna , Gupta Ankit 
Published: December 2022

AbstractChronic exposure to fluoride through drinking water has been linked to insulin resistance and resulting type 2 diabetes mellitus (T2DM). Here, we aim to study the impact of water fluoride levels on blood glucose and vitamin D levels. A hospital-based study was conducted on diabetic patients (n = 303) at All India Institute of Medical Sciences (AIIMS), Raebareli outstation patient department (OPD). The relationship between vitamin D or fasting blood glucose levels (BGLs) with water fluoride levels was estimated through Spearman's rank correlation. We found a significant negative correlation between water fluoride and vitamin D levels [rs = −0.777, p-value &lt; 0.001] and a positive correlation between water fluoride and fasting BGLs [rs = 0.178, p-value &lt;0.05]. The participants residing in fluoride-endemic areas (F &gt; 1.5 mg/L) had higher odds of severe vitamin D deficiency (odds ratio: 5.07, 95% CI: 1.9–13.2, p-value = 0.0009). The results demonstrate that vitamin D deficiency and fasting BGLs are significantly associated with water fluoride levels. This study signifies the role of fluoride toxicity in poor glycemic control and derived vitamin D deficiency. Vitamin D supplementation and the application of standard household water purification devices are recommended to tackle vitamin D deficiency in fluoride-endemic areas.

Published: December 2022

Clinicians face challenges managing patients at the end-of-life (EOL). A focus group discussion (FGD) of nine clinicians was conducted to explore their experiences. Verbatim was transcribed and thematically analysed based on grounded theory. 18 issues affecting EOL care decisions emerged and can be categorised into three categories: family-related issues, doctor-related issues and system-related issues. The findings suggest that the surrogacy ladder commonly used in decision-making for incapacitated patients in Malaysia is as follows: spouses followed by children, parents, and siblings. The results of this FGD can help policymakers develop guidelines on EOL decision-making suitable for use in the local context.

Published: December 2022

p>The provision of affordable housing for the low and middle-income class may enhance the quality of life of this social group. In addition, cooperation from stakeholders must be greater in promoting affordable houses in the market. However, the low-profit margin and other constraints reduced the supply of affordable homes by housing developers. Therefore, this research examines the factors and attributes that may affect housing developers in supplying affordable houses. Total 120 responses from housing developers were gathered via questionnaires and analysed by using Partial Least Square Modelling (PLS-SEM) for the development of an affordable housing supply model. The result displays three factors with 11 attributes that affect housing suppliers.

Conversational Agents and Avatars for Cardiometabolic Risk Factors and Lifestyle-Related Behaviors: Scoping Review
Authors: Lyzwinski Lynnette Nathalie , Elgendi Mohamed , Menon Carlo 
Published: December 2022

Background
In recent years, there has been a rise in the use of conversational agents for lifestyle medicine, in particular for weight-related behaviors and cardiometabolic risk factors. Little is known about the effectiveness and acceptability of and engagement with conversational and virtual agents as well as the applicability of these agents for metabolic syndrome risk factors such as an unhealthy dietary intake, physical inactivity, diabetes, and hypertension.

Objective
This review aimed to get a greater understanding of the virtual agents that have been developed for cardiometabolic risk factors and to review their effectiveness.

Methods
A systematic review of PubMed and MEDLINE was conducted to review conversational agents for cardiometabolic risk factors, including chatbots and embodied avatars.

Results
A total of 50 studies were identified. Overall, chatbots and avatars appear to have the potential to improve weight-related behaviors such as dietary intake and physical activity. There were limited studies on hypertension and diabetes. Patients seemed interested in using chatbots and avatars for modifying cardiometabolic risk factors, and adherence was acceptable across the studies, except for studies of virtual agents for diabetes. However, there is a need for randomized controlled trials to confirm this finding. As there were only a few clinical trials, more research is needed to confirm whether conversational coaches may assist with cardiovascular disease and diabetes, and physical activity.

Conclusions
Conversational coaches may regulate cardiometabolic risk factors; however, quality trials are needed to expand the evidence base. A future chatbot could be tailored to metabolic syndrome specifically, targeting all the areas covered in the literature, which would be novel.
