In this paper, we present an intensive investigation of the finite volume method compared to the finite difference methods. In order to show the main difference in the way of approaching the solution, we take the Burgers equation and the Buckley–Leverett equation as examples to simulate the previously mentioned methods. On the one hand, we simulate the results of the finite difference methods using the schemes of Lax–Friedrichs and Lax–Wendroff. On the other hand, we apply Godunov’s scheme to simulate the (...) results of the finite volume method. Moreover, we show how starting with a variational formulation of the problem, the finite element technique provides piecewise formulations of functions defined by a collection of grid data points, while the finite difference technique begins with a differential formulation of the problem and continues to discretize the derivatives. Finally, some graphical and numerical comparisons are provided to illustrate and corroborate the differences between these two main methods. (shrink)

In their report for the Swiss government onthe notion of the dignity of creatures, PhilippBalzer, Klaus-Peter Rippe, and Peter Schaber analyzethe relationship between human dignity and the dignityof creatures, taking them as two categoricallydifferent concepts. Human dignity is defined as the``moral right not to be humiliated,'' whereas thedignity of creatures is taken to be ``the inherentvalue of nonhuman living beings.'' To my mind there isno need to draw a categorical distinction between thetwo concepts. Both notions could be brought togetherunder an (...) all-encompassing concept of the inherentvalue of living beings, humans and non-humans alike,a concept one could name ``the dignity of livingbeings.'' Indeed, this very notion underlies theposition taken in the report, although this is notmade explicit by the authors themselves.As the aim of the paper is only to clarify theconcepts used, I do not go beyond this ``internal''critique of their position, i.e., I don't assess howthe claims articulated via these concepts – theclaim that humans and/or creatures have an inherentvalue consisting in a supposed intrinsic good – areto be justified, although I myself would be ratherskeptical that this might be successfully done.

Radiography images are widely utilized in the health sector to recognize the patient health condition. The noise and irrelevant region information minimize the entire disease detection accuracy and computation complexity. Therefore, in this study, statistical Kolmogorov–Smirnov test has been integrated with wavelet transform to overcome the de-noising issues. Then the cat swarm-optimized deep belief network is applied to extract the features from the affected region. The optimized deep learning model reduces the feature training cost and time and improves the overall (...) disease detection accuracy. The network learning process is enhanced according to the AdaDelta learning process, which replaces the learning parameter with a delta value. This process minimizes the error rate while recognizing the disease. The efficiency of the system evaluated using image retrieval in medical application dataset. This process helps to determine the various diseases such as breast, lung, and pediatric studies. (shrink)

The Self We Live By confronts the serious challenges facing the self in postmodern times. Taking issue with contemporary trivializations of the self, the book traces a course of development from the early pragmatists who formulated what they called the 'empirical self', to contemporary constructionist views of the storied self. Presenting an institutional context for the increasing complexity and ubiquity of narrative identity, the authors illustrate the 'everyday technology of self construction' and idscuss the resulting moral climate. The book is (...) suitable for advanced undergraduates and graduate students in courses such as Individual in Society, Contemporary American Society, Social Psychology, Social Interaction and Culture & Personality.

Background Integrating artificial intelligence (AI) into healthcare has raised significant ethical concerns. In pharmacy practice, AI offers promising advances but also poses ethical challenges. Methods A cross-sectional study was conducted in countries from the Middle East and North Africa (MENA) region on 501 pharmacy professionals. A 12-item online questionnaire assessed ethical concerns related to the adoption of AI in pharmacy practice. Demographic factors associated with ethical concerns were analyzed via SPSS v.27 software using appropriate statistical tests. Results Participants expressed concerns (...) about patient data privacy (58.9%), cybersecurity threats (58.9%), potential job displacement (62.9%), and lack of legal regulation (67.0%). Tech-savviness and basic AI understanding were correlated with higher concern scores (p < 0.001). Ethical implications include the need for informed consent, beneficence, justice, and transparency in the use of AI. Conclusion The findings emphasize the importance of ethical guidelines, education, and patient autonomy in adopting AI. Collaboration, data privacy, and equitable access are crucial to the responsible use of AI in pharmacy practice. (shrink)

Dass die Würde des Menschen unantastbar sei, stellt eine der populärsten, aber auch eine der umstrittensten Aussagen des Grundgesetzes dar. Dabei wird eine sachorientierte Diskussion oft durch mehr oder minder unausgewiesene semantische und historische Annahmen blockiert. Aus dieser Beobachtung heraus wird zum einen überlegt, wie sich unterschiedliche Bedeutungen des Ausdrucks "Menschenwürde" unterscheiden und ethischen Fragestellungen resp. Positionen zuordnen ließen. Zum anderen wird die Einführung des Ausdrucks in das Verfassungsrecht nachgezeichnet. Das Hauptaugenmerk gilt dabei Art.1 Abs. 1 Grundgesetz, dessen Gehalt in (...) Auseinandersetzung mit der bisherigen Rechtsprechung rekonstruiert wird. (shrink)

Content-based image retrieval (CBIR) is a technique used to retrieve image from an image database. However, the CBIR process suffers from less accuracy to retrieve many images from an extensive image database and prove the privacy of images. The aim of this article is to address the issues of accuracy utilizing deep learning techniques such as the CNN method. Also, it provides the necessary privacy for images using fully homomorphic encryption methods by Cheon–Kim–Kim–Song (CKKS). The system has been proposed, namely (...) RCNN_CKKS, which includes two parts. The first part (offline processing) extracts automated high-level features based on a flatting layer in a convolutional neural network (CNN) and then stores these features in a new dataset. In the second part (online processing), the client sends the encrypted image to the server, which depends on the CNN model trained to extract features of the sent image. Next, the extracted features are compared with the stored features using a Hamming distance method to retrieve all similar images. Finally, the server encrypts all retrieved images and sends them to the client. Deep-learning results on plain images were 97.87% for classification and 98.94% for retriever images. At the same time, the NIST test was used to check the security of CKKS when applied to Canadian Institute for Advanced Research (CIFAR-10) dataset. Through these results, researchers conclude that deep learning is an effective method for image retrieval and that a CKKS method is appropriate for image privacy protection. (shrink)

We prove that in a nilpotent-by-finite stable group an equation that holds generically holds everywhere. Combining this result with results of Wagner and Bryant, we conclude that a soluble-by-finite stable group of generic exponent n has exponent n.

Internet-of-Things (IoT) creates a significant impact in spectrum sensing, information retrieval, medical analysis, traffic management, etc. These applications require continuous information to perform a specific task. At the time, various intermediate attacks such as jamming, priority violation attacks, and spectrum poisoning attacks affect communication because of the open nature of wireless communication. These attacks create security and privacy issues while making data communication. Therefore, a new method autoencoder deep neural network (AENN) is developed by considering exploratory, evasion, causative, and priority (...) violation attack. The created method classifies the transmission outcomes used to predict the transmission state, whether it is jam data transmission or sensing data. After that, the sensing data is applied for network training that predicts the intermediate attacks. In addition to this, the channel access algorithm is used to validate the channel for every access that minimizes unauthorized access. After validating the channel according to the neural network, data have been transmitted over the network. The defined process is implemented, and the system minimizes different attacks on various levels of energy consumption. The effectiveness of the system is implemented using TensorFlow, and the system ensures the 99.02% of detection rate when compared with other techniques. (shrink)

IntroductionFew studies have examined psychological distress in healthcare workers across the care continuum. This study describes distress levels reported by HCWs across care settings and factors associated with distress.MethodsA cross-sectional survey of HCWs from Windsor, Ontario, was conducted between May 30th, 2020, and June 30th, 2020. The survey included the Kessler Psychological Distress Scale, sociodemographic, frontline status, perceptions of training, protection, support, respect among teams, and professional and personal stressors. Univariate analyses were used to compare across settings and multivariate logistic (...) regression assessed factors associated with distress.ResultsFour hundred and three HCWs from the hospital, community health and social service, first responder, primary care, home, and long-term care participated in the survey. Common concerns included fear of transmitting COVID-19 to family, safety on the job, and balancing personal care with work demands. LTC and home-care HCWs reported greater concern about workload and staffing levels, whereas community health workers were more anxious about their financial security. Overall, 228 HCWs who completed the K10 reported high distress, with greater rates among hospital and LTC HCWs. Distress was more likely in HCWs who identified as female, younger than 55, perceived lower respect among team, and experienced greater worry about physical and mental health and managing high workloads.ConclusionResults showed a high degree of distress experienced by HCWs across care settings and the impact of the COVID-19 pandemic on personal and work-related stress. Promoting self-care and supportive and collaborative healthcare teams are promising avenues for mitigating symptoms of distress. (shrink)

At the very beginning of L’Homme-Machine, La Mettrie claims that Leibnizians with their monads have “rather spiritualized matter than materialized the soul”; a few years later Pierre-Louis Moreau de Maupertuis, President of the Berlin Academy of Sciences and natural philosopher with a strong interest in the modes of transmission of ‘genetic’ information, conceived of living minima which he termed molecules, “endowed with desire, memory and intelligence,” in his Système de la nature ou Essai sur les corps organisés. This text first (...) appeared in Latin in 1751 under the title Dissertatio inauguralis metaphysica de universali naturae systemate, with the pseudonym Dr Baumann; it was translated by Maupertuis in 1754 as Essai sur la formation des corps organisés and was later included in his 1756 Œuvres under the title Système de la nature. Now, it is clear that Maupertuis was a kind of Leibnizian; and that his molecule possessed higher-level, ‘mental’ properties. In that sense he falls under the first category described by La Mettrie. But he was also involved in a debate on this issue with Diderot, who put forth a sustained critique of Maupertuis’ theory of the molecule in the additions to his 1753 Pensées sur l’interprétation de la nature. Where Maupertuis attributes higher-level properties to his living minima, Diderot argues that these properties are ‘organizational’, i.e., they can only be properties of the whole. At issue here is the degree of commitment to a form of materialism. (shrink)

"This is an excellent textbook on Neoplatonism which gives the reader a very concise and lucid overview of the basic doctrines and leading thinkers of the last great philosophy to emerge before the Christianization of the Roman Empire. I’ve no doubt that my students next semester will benefit from the analyses contained in the book. The contents of the chapters are very informative and adequately place developments in their socio-cultural context." --Michael B. Simmons, Auburn University at Montgomery.

Nowadays, lung cancer is one of the most dangerous diseases that require early diagnosis. Artificial intelligence has played an essential role in the medical field in general and in analyzing medical images and diagnosing diseases in particular, as it can reduce human errors that can occur with the medical expert when analyzing medical image. In this research study, we have done a systematic survey of the research published during the last 5 years in the diagnosis of lung cancer classification of (...) lung nodules in 4 reliable databases, and we selected 50 research paper using systematic literature review. The goal of this review work is to provide a concise overview of recent advancements in lung cancer diagnosis issues by machine learning and deep learning algorithms. This article summarizes the present state of knowledge on the subject. Addressing the findings offered in recent research publications gives the researchers a better grasp of the topic. We checked all the characteristics, such as challenges, recommendations for future work were analyzed in detail, and the published datasets and their source were presented to facilitate the researchers’ access to them and use it to develop the results achieved previously.

In his Philosophical Inquiry concerning Human Liberty (1717), the English deist Anthony Collins proposed a complete determinist account of the human mind and action, partly inspired by his mentor Locke, but also by elements from Bayle, Leibniz and other Continental sources. It is a determinism which does not neglect the question of the specific status of the mind but rather seeks to provide a causal account of mental activity and volition in particular; it is a ‘volitional determinism’. Some decades later, (...) Diderot articulates a very similar determinism, which seeks to recognize the existence of “causes proper to man” (as he says in the Réfutation d’Helvétius). The difference with Collins is that now biological factors are being taken into account. Obviously both the ‘volitional’ and the ‘biological’ forms of determinism are noteworthy inasmuch as they change our picture of the nature of determinism itself, but my interest here is to compare these two determinist arguments, both of which are broadly Spinozist in nature – and as such belong to what Jonathan Israel called in his recent book “the radical Enlightenment,” i.e. a kind of underground Enlightenment constituted by Spinozism – and to see how Collins’ specifically psychological vision and Diderot’s specifically biological vision correspond to their two separate national contexts: determinism in France in the mid-1750s was a much more medico-biological affair than English determinism, which appears to be on a ‘path’ leading to Mill and associationist psychology.

This volume emphasizes the diversity and fruitfulness of early modern mechanism as a program, as a concept, as a model. Mechanistic study of the living body but also of the mind and mental processes are examined in careful historical focus, dealing with figures ranging from the first-rank (Bacon, Descartes, Spinoza, Cudworth, Gassendi, Locke, Leibniz, Kant) to less well-known individuals (Scaliger, Martini) or prominent natural philosophers who have been neglected in recent years (Willis, Steno, etc.). The volume moves from early modern (...) medicine and physiology to late Enlightenment and even early 19th-century psychology, always maintaining a conceptual focus. It is a contribution to a newly active field in the history and philosophy of early modern life science. It is of interest to scholars studying the history of medicine and the development of mechanistic theories. (shrink)

The living body appears like an endlessly renewable reservoir of authenticity, hope, and taboo. But, for the sake of conceptual clarity, we are often been told that the (mere) body should be distinguished from the flesh. That is, it’s undeniable that I have a body; that I notice yours; that we worry about their birth and death and upkeep. But the flesh is a more transcendentalized, loaded concept – not least given its frequently religious background (incarnation: the Word made Flesh). (...) It is the body ‘kicked upstairs’, ‘bumped up’ one ontological level. Flesh is like a mantra, an obsessive leitmotif. Is the difference just one of abstraction? Indeed, crucial to the narrative of phenomenology (most obviously in Merleau-Ponty but really, throughout, including in enactivism), to the story of ancestor worship and identity it tells itself and its acolytes around the campfire, is a basic distinction between the merely physical body and the flesh as something requiring ‘mineness’, namely, an understanding of it as uniquely ‘my own’, a feeling of ‘what it is like to be embodied’. This goes back to the Husserlian distinction between Körper, ‘body’ in the sense of one body among others in a vast mechanistic universe of bodies, and Leib, ‘flesh’ in the sense of a subjectivity which is the locus of experience. In this essay I reflect on this vision of the body’s authenticity and its costs, and contrast it with insights derived from Georges Canguilhem, whose critique of mechanism/mechanicism is not done in the name of a wholescale organicism and/or an unproblematized éloge of embodiment and privacy.

A patient with a history of bipolar II disorder and endstage renal disease who required hemodialysis for five years abruptly wished to withdraw from dialysis on day seven of her hospital admission for a urinary tract infection. She had never discussed wishing to withdraw from dialysis prior to this hospital admission. She had experienced several symptoms of depression during her stay. Her desire to withdraw from dialysis treatment was discordant with her previously expressed desires, and the psychiatry team determined that (...) her judgment was likely altered by her depressive episode. Given her previous positive response to electroconvulsive therapy (ECT), the psychiatry team recommended that she receive ECT before she choose to withdraw from dialysis. (shrink)
