The Internet of Things (IoT) is a rapidly growing technology that connects and integrates billions of smart devices, generating vast volumes of data and impacting various aspects of daily life and industrial systems. However, the inherent characteristics of IoT devices, including limited battery life, universal connectivity, resource-constrained design, and mobility, make them highly vulnerable to cybersecurity attacks, which are increasing at an alarming rate. As a result, IoT security and privacy have gained significant research attention, with a particular focus on (...) developing anomaly detection systems. In recent years, machine learning (ML) has made remarkable progress, evolving from a lab novelty to a powerful tool in critical applications. ML has been proposed as a promising solution for addressing IoT security and privacy challenges. In this article, we conducted a study of the existing security and privacy challenges in the IoT environment. Subsequently, we present the latest ML-based models and solutions to address these challenges, summarizing them in a table that highlights the key parameters of each proposed model. Additionally, we thoroughly studied available datasets related to IoT technology. Through this article, readers will gain a detailed understanding of IoT architecture, security attacks, and countermeasures using ML techniques, utilizing available datasets. We also discuss future research directions for ML-based IoT security and privacy. Our aim is to provide valuable insights into the current state of research in this field and contribute to the advancement of IoT security and privacy. (shrink)

To counter a general belief that all the paradoxes stem from a kind of circularity (or involve some self--reference, or use a diagonal argument) Stephen Yablo designed a paradox in 1993 that seemingly avoided self--reference. We turn Yablo's paradox, the most challenging paradox in the recent years, into a genuine mathematical theorem in Linear Temporal Logic (LTL). Indeed, Yablo's paradox comes in several varieties; and he showed in 2004 that there are other versions that are equally paradoxical. Formalizing these versions (...) of Yablo's paradox, we prove some theorems in LTL. This is the first time that Yablo's paradox(es) become new(ly discovered) theorems in mathematics and logic.

Presentists argue that only present entities exist absolutely and unrestrictedly. Presentism, which itself is a temporal analog of the modal doctrine of actualism, is an ontological idea about time and existence against theories such as eternalism, possibilism, and growing block theory. Thus, presentists deny the existence of atemporal or timeless entities and describe presentism as a version of the (A-theory), which makes a difference between present, past, and future. Also, presentists are not able to ontologically, justify the existence of some (...) entities such as Socrates and the year 3000 in the past and the future and the relations involving non-present objects like ‘Abraham Lincoln was taller than Napoleon Bonaparte’. However, presentism is altered via the addition of an abstract four-dimensional manifold of ersatz time, which is a type of (B-theory) series, to identify all ontological entities and justify the dynamic world. This inquiry is an attempt to put a completely different perspective on presentism and, the result obtained that despite the new conceptualization of time, there is an inconsistency between time and being in presentism. Therefore, presentists have failed to determine the ontological identification of cross-temporal relations, reference and propositions, and truth-makers. Also, whatever the final outcome of the debate between presentism and other views is significantly eternalism, according to ersatz presentism, it is hard to make sense of the idea that things change from one moment to the next.

Abstract In the light of the analysis of Avicenna’s definition of “nature” we can discover the main principles of his physics, which are: ‘The agency of the nature’, ‘the directness of this agency’, ‘the natural object’, and ‘the essential agency of the nature’. One of the main consequences of this analysis is that the nature could be considered as the direct cause of the motion, immobility and spatial balance of the material objects. Moreover, it shows that natural objects are essentially (...) capable of possess natural properties. Accordingly, Avicenna considers that the natural properties are the same as the essential properties, which material objects have them necessarily. (shrink)

Reflecting on Avicenna’s works indicates that by ‘Dhat’(ذات), when used in the context of universal essences, he means either the quiddity or the nature, and when used in the context of individual essence, especially God’s essence, he means the very existence. The second meaning, i.e. the nature, which is the result of his inquiry about the reality of things, is based on the first one, i.e. the quiddity. According to this second meaning, and througha kind of thought experiment and using (...) human mind’s capacity, Avicenna discusses different aspects of essence and their implications in various sciences. These conceptual analyses help us discover his idea of essentialism. The final conclusion is that Avicenna’s essentialism is consistent with his idea about existence and the definitions can refer to the essence of objects. (shrink)

The problem of natural kind is considered to be a complicated problem in philosophy as it is linked to the problem of essence on the one hand and the problem of individuals on the other. While nominalists refuse to accept universals in their ontology, realists believe in natural kinds and endeavor to justify classification of things by appealing to existence of natural kinds and their essential properties. In the first part of this paper we briefly survey two kinds of criteria (...) for being a natural kind. In the second part we will evaluated the proposed criteria. Finally we conclude by the following six criteria: Reality and absoluteness, possessing of full essence, hierarchy, changelessness, categorization and contribution to identical theory. (shrink)

Since time immemorial, due to its metaphysically grounded perspective, western philosophy has not been able to detach itself from the egoistic outlook, and thus, the interaction with the "other” had no role in this philosophy. The world has always been interpreted from the perspective of "self" ignoring the "other". Reviewing this mode of thought from Ancient Greece to Modern Age, one can reveal a kind of repression and forgetfulness of "alterity" and difference which Levinas has well highlighted in his philosophy. (...) The very foundation of this egoism can be traced back to the Socratic slogan "know yourself”. In the same spirit, a kind of self-centered moral philosophy has been developed, the clear example of which is Kant's ethics. In line with Hegelian tradition of recognition, contemporary thinkers have redefined ethics and politics and acknowledged the constitutional dependence of the “self” on the "other." Based on the coordinates of their thought as well as the historical condition of their own time in the formation of subjectivity, these thinkers have criticized the neglect of the “other”. Hegel's role in underlining the importance of the vital status of the “other” is unique. Hegel bridges all post-Hegelian currents on the concept of “Other”. Then, in the present essay, we seek to show that since Hegel’s time up to Derrida, we have been witness to the rise of “Other” and the fall of “Self”. -/- . (shrink)
