This work introduces a three-dimensional, highly nonlinear quadratic oscillator with no linear terms in its equations. Most of the quadratic ordinary differential equations such as Chen, Rossler, and Lorenz have at least one linear term in their equations. Very few quadratic systems have been introduced and all of their terms are nonlinear. Considering this point, a new quadratic system with no linear term is introduced. This oscillator is analyzed by mathematical tools such as bifurcation and Lyapunov exponent diagrams. It is (...) revealed that this system can generate different behaviors such as limit cycle, torus, and chaos for its different parameters’ sets. Besides, the basins of attractions for this system are investigated. As a result, it is revealed that this system’s attractor is self-excited. In addition, the analog circuit of this oscillator is designed and analyzed to assess the feasibility of the system’s chaotic solution. The PSpice simulations confirm the theoretical analysis. The oscillator’s time series complexity is also investigated using sample entropy. It is revealed that this system can generate dynamics with different sample entropies by changing parameters. Finally, impulsive control is applied to the system to represent a possible solution for stabilizing the system. (shrink)

Who am I? What is my true identity? What is the nature of self? Deepest self? What is the nature of the world? How are self and world related? What is the highest goal of life? These are the questions that Indian philosophy has wrestled with for millennia. Many of the answers it has produced are intimately involved with spirituality, both mystical and theistic. This work, called Self and World: Major Aspects of Indian Philosophy, by Ramesh N. Patel, explores (...) these time-tested answers that are deeply interesting, engrossing and enlightening. Yoga and Vedanta are two of the well-known philosophies of India that have attempted answers to the above questions about self and world. The classical Indian philosophy’s answers to questions about self and world span no less than three distinct religions and their spiritualities: Hinduism, Buddhism and Jainism. Besides yoga and vedanta, Hinduism has four other answers that have conversed with yoga and vedanta for centuries. Buddhism has four distinct answers that too have conversed with these philosophical and spiritual answers. These conversations have led to very productive exchanges by enriching the resulting development and evolution of each system’s answers. The exchange has made the philosophies stronger and diverse. The present work explores and describes these systems in their mature form which preserves their accumulated wisdom.Another feature of this work is its treatment of the philosophy of the ancient texts called the Vedas. Pandit Madhusudan Ojha has unearthed the lost philosophy contained in the Vedas. This Vedic philosophy sports a highly comprehensive yet coherent and relevant system of thought that is also important for its tremendous influence on all later Indian systems including yoga, vedanta and Buddhist systems. This book articulates Vedic philosophy and its historic influence on the thought on self and world in Indian philosophy. The deeply spiritual embedding of Indian philosophy’s thought about self and world is particularly relevant to today’s strife-torn and polarized world. We need themes of unity in diversity for healing current maladies. The spiritual thought systems of Indian philosophy narrated in the present work provide an array of choices which have great potential for this healing. For example, Buddhism is celebrated for its universal compassion, Jainism for its legendary non-violence and Hinduism for its tolerance of differences and respect for other faiths. This book shows how these positions are intellectually strengthened and secured by the Buddhist, Jain and Hindu thinkers. (shrink)

This article is an obituary on the life and works of Professor G. C. Nayak who was a renowned philosopher of India in the contemporary times. He has contributed immensely to philosophy and has many books and scholarly papers to his credit. The philosophy community mourns his death.

The necessity for introducing interactionist and parallelism approaches in different branches of cognitive science emerged as a reaction to classical sequential stage-based models. Functional psychological models that emphasized and explained how different components interact, dynamically producing cognitive and perceptual states, influenced multiple disciplines. Chiefly among them were experimental psycholinguistics and the many applied areas that dealt with humans’ ability to process different types of information in different contexts. Understanding how bilinguals represent and process verbal and visual input, how their neural (...) and psychological states facilitate such interactions, and how linguistic and nonlinguistic processing overlap, has now emerged as an important area of multidisciplinary research. In this article, we will review available evidence from different language-speaking groups of bilinguals in India with a focus on situational context. In the discussion, we will address models of language processing in bilinguals within a cognitive psychological approach with a focus on existent models of inhibitory control. The paper's stated goal will be to show that the parallel architecture framework can serve as a theoretical foundation for examining bilingual language processing and its interface with external factors such as social context.

As part of the special issue on “The United Nations at Seventy-Five: Looking Back to Look Forward,” this essay connects the past of the United Nations to its future from the perspective of the Global South. When the UN was created, most developing countries were colonies that played no role in writing the rules and designing the architecture of the post-1945 UN-centric global multilateral order. Today, countries in the Global South command a majority of the UN membership, but still mostly (...) function as norm takers and are severely underrepresented in the UN Security Council—which functions as the geopolitical cockpit—and also in the senior ranks of the UN system, in the key posts in the Secretariat, and in the UN's funds and agencies. Gradually, however, these countries are using their numerical strength to give voice to their distinctive preferences, priorities, and values. This essay provides a broad-brush sketch of the changing nature of the North-South partnership on the UN's four overarching normative mandates of security, development, environment, and human rights. It includes a brief comment on the coronavirus pandemic within the framework of its main narrative of the continuing need for a UN-centric North-South partnership. (shrink)

Deep and universal spirituality is evident in the life and teachings of all the founders of great world faiths. Over time, however, it gets clouded under the institutional and doctrinal structure of the religion that surrounds it. This book, Interfaith Spirituality: Toward Universal Faith beyond Dogmas, by Ramesh N. Patel, stands out by emphasizing and articulating the noble and inspirational spirituality of world faiths, Eastern and Western. The faiths chosen for narration are Judaism, Christianity, Islam, Taoism, Confucianism, Buddhism and (...) Hinduism. -/- The book goes farther than bringing out the spirituality of Eastern and Western faiths. For, it offers intellectually sound thinking toward relieving the age-old tensions between faiths, such as the numinous and the mystical, monotheism and non-dualism, privileging of believers against open-ended tolerance of differences and so on. -/- A further standout feature of the book is its diving deep to pick out pearls of spiritual wisdom from the world faiths and weaving them into thoughtful necklaces which it calls thought experiments in world spirituality. To top it all is offered an optimal universal spirituality that is comprehensive in scope and universal in application. It manifests a flower with spiritual outlines in four petals of work, faith, concept and contemplation. Spiritual seekers from diverse dimensions of life will find this useful and supportive. -/- The book, Interfaith Spirituality, thus is not just innovative. It offers a message of healing and calming moderation for a world that is torn by polarizing conflicts of various sorts. (shrink)

The phenomenon of dreamless sleep and its philosophical consequences, particularly deep sleep's relevance to such issues as Self, Consciousness, Personal Identity, Unity of Subject, and Disembodied Life, are explored through a discussion, in varying detail, of certain noted doctrines and views--for example of Advaita Vedānta, Hegel, and H. D. Lewis. Finally, with a cue from Leibniz and McTaggart, the suggestion is made that at no stage during sleep is the self without some perceptions, however indeterminate. Support for this hypothesis is (...) claimed from the current psychoanalytic opinion that mental activity does not cease during any part of sleep and that human beings continue to dream even in the so-called dreamless state.

The paper entitled ‘Anthropocentric teleological environmental ethics’ is quite suggestive. I have tried to pinpoint that environmental ethics is both anthropocentric and teleological. I contend that man is the sole bearer of values. Environment serves human purpose. Man gives values to environment or Mother Earth. Indians with their reverence for sacred rivers have always been close to nature. I propose integral teleological environmental ethical theory which integrates man and nature, deontological and teleological theories. It reconciles between anthropocentric and non-anthropocentric views (...) of environment. (shrink)

This baseline study was conducted to find out the knowledge, attitudes and practices of medical ethics among the undergraduate medical interns who did not have structured ethics curriculum in their course. A descriptive, cross-sectional study was carried out using a self-administered structured questionnaire among the medical undergraduate interns of Maharajgunj Medical Campus, the pioneer medical college of Nepal which enrols 60 students in a year. A total of 46 interns participated in the study. The most common source of knowledge on (...) ethics was lectures/seminars (35.7%) followed by experience at work (24.5%), training (21.4%) and own reading (17.3%). The main contents of Hippocratic Oath were known to 98.8% while 60.9% knew the main contents of Nepal Medical Council (NMC) code of ethics. Great majority (91.3%) regard ethics as very important in medical profession. “Doctors know the best irrespective of patients’ opinion” was disagreed by only 39.1% indicating the paternalistic attitude. However, 78.3% were in favour of adhering to the patient’s wish. None of the participant agreed to abandon confidentiality. Only about one-fourth (26.1%) claim to encounter ethical dilemma every day while the highest number (43.5%) had once in a month. To deal with the situation of ethical dilemma, majority approached to immediate supervisor followed by head of the department and colleagues. Eighty-seven percent of participating interns were involved in research activities involving human subjects. Only one of the participants had encountered the ethical issue on end-of-life and it was do-not-resuscitate consent in a terminally ill patient. On implementation of the curriculum on medical ethics focus should be - principles of biomedical ethics, sensitive ethical dilemmas like end-of-life care and practical experiences with participation in deliberations of the ethics committee.

The book called "Philosophy of the Gita," by Prof. Ramesh N. Patel, is a striking philosophical study of the celebrated Sanskrit text called the Bhagavad-gita which is known simply as the Gita. Patel's book proposes and develops a new hermeneutic called archaic coherentism and applies it to the Gita to distill and decode a comprehensive metaphysic and philosophy of action embedded in the text. A new conceptual translation of the Sanskrit text brings out this philosophy in clear detail. Philosophical (...) essays preceding the translation include analysis of the often-neglected background of war and morality, discussion of action, freedom and self-identity, delineation of a new synoptic philosophy of Hinduism, and unearthing of a strikingly original and innovative metaphysics of existence, energy and triple individuation. The translation of the Gita is followed by two critical essays called "Emerging Philosophy" and "Coherence and Exegesis." Patel's translation focuses on the conceptual rendering of every term, with no Sanskrit word left untranslated, even including the tough ones like guna and Brahman. The essay called "Emerging Philosophy" does away with all Sanskrit terms, to facilitate the understanding of the newly decoded Gita's philosophy as a whole. The essay called "Coherence and Exegesis" critically examines several scholarly standpoints on the Gita with Patel's sound philosophical reasoning. The innovative philosophy of the Gita that emerges through the book's analysis includes an original theory of individuation revealing a Platonic-type Form of individuation evolving at three levels: essential, actional and physical. The book is written for professional philosophers and Sanskritist Indologists. It generally assumes familiarity with logical problems of philosophy and with Sanskrit terms in Indian philosophy. The author has a rare dual training in Sanskrit and philosophy. He skillfully exploits both in this book to achieve an unusual outcome that should be of great interest and challenge to both professional philosophers as well as scholars of Indology. (shrink)

What is Hinduism? Who is a Hindu? What form should Hinduism take in this day and age? This book proposes serious answers to these important challenging questions and presents them in an engaging way. Four men and four women, committed Hindus from different walks of life, gather under the format of a seminar to discuss these questions. They engage in the hard thinking necessary to develop a four-point definition of Hinduism. They construct foundations of a moderate viable Hinduism using the (...) definition. They show how different structures can be built on the foundations allowing expression of individual creativity and freedom. The book is the dialog of the eight diverse Hindus who show human emotions and passion along with acute reasoning, evolving a fascinating discourse. They traverse far and wide over the panorama of world religions as well as Eastern and Western philosophy. The result is a comprehensive philosophy of life that can inspire and empower not only Hindus but also all humans deeply interested in universal humanistic spirituality with competitive intellectual underpinning relevant for today.

Current EEG research emphasizes gamma band coherence as a signature of functional integration, that is, the solution to the binding problem. We note that spatial patterns of coherent neural activity are also observed at other EEG frequencies. If these oscillations reflect Nunez's resonant modes, they offer a solution to the binding problem that emerges naturally from the architecture of cortical connections.

This substantive and important book, Seeing One in Many, by Professor Ramesh N. Patel, serves many needs and purposes. It also stands out in several ways. -/- First, seeing one spiritual being in our manifold universe is a hallmark of all spirituality. Highlighting this spirituality as a main feature of the world’s oldest living religion has obvious healing potential for the world’s polarizing conflicts of sundry nature that we have been witnessing with concern for a while. -/- This religion (...) happens to be one of the largest in the world. As such, it carries relevance for a significant section of humanity. Hinduism, called Sanatana Dharma, or eternal religion by many of its practitioners, has a lot to offer to the world community of spiritual seekers. However, this positive and constructive aspect of Hinduism has been overshadowed by negative image created by unsympathetic forces over the last couple of centuries. This work makes this manifest in an accessible dialog style. -/- The author puts his expertise in Sanskrit to skillful use in bringing out major features of spirituality embedded in the original Sanskrit literature which is the home of Hindu scriptures. As a trained Sanskritist he guides the reader beyond the daunting complexity and diversity of Hindu beliefs and practices toward a gentle but deep understanding of the defining themes of the Hindu spirituality. -/- Further, Ramesh utilizes his five decades of teaching experience in world religions for an effective and fruitful comparison of Hinduism with both other Eastern as well as Western religions of the world. The book is filled with thoughtful insights that bring the rich diversity of spiritual outlooks in world history to show how Hindu spirituality stands in relation to them. -/- Then, Ramesh exploits his training and specialization in Western philosophy to draw contrasts and comparisons of Western ethical theories with the Hindu value philosophy. He clearly shows how the Hindu philosophy comes out as a remarkably coherent integration of many theories of Western ethics. Ramesh also uses the Western logical notions of stipulative and descriptive definition to blend them with the classical indigenous ideas of external or tatastha and internal or svarupa lakshana or definition. The result is a salient four-point definition of Hinduism. -/- Like all mature traditions, Hinduism has its spectrum of outlooks ranging from radical left to radical right. Ramesh presents three major points of the spectrum of conservative, reform and moderate Hinduism. A productive dialog is depicted where a balanced moderate Hinduism emerges. -/- Toward the end of the book’s dialog, Ramesh applies his teaching experience in philosophy of science, history and social sciences to build further on the unique definition of Hinduism thus achieved. In all, this book is a solid comprehensive enunciation of Hindu thought and spirituality which should reward anyone with more than casual interest in the subject plentifully. -/- Ramesh N. Patel was Professor of Philosophy and Religion at Antioch College. He retired in 2002 after teaching for twenty-five years. He continues to teach voluntary courses in Bhagavad-gita, Upanishads, Hinduism and Spirituality Studies. (shrink)

Study of Vivekacūḍāmaṇi of Śaṅkarācārya, work on Vedanta philosophy.

Day-to-day lives are affected globally by the epidemic coronavirus 2019. With an increasing number of positive cases, India has now become a highly affected country. Chronic diseases affect individuals with no time identification and impose a huge disease burden on society. In this article, an Efficient Recurrent Neural Network with Ensemble Classifier is built using VGG-16 and Alexnet with weighted model to predict disease and its level. The dataset is partitioned randomly into small subsets by utilizing mean-based splitting method. Various (...) models of classifier create a homogeneous ensemble by utilizing an accuracy-based weighted aging classifier ensemble, which is a weighted model’s modification. Two state of art methods such as Graph Sequence Recurrent Neural Network and Hybrid Rough-Block-Based Neural Network are used for comparison with respect to some parameters such as accuracy, precision, recall, f1-score, and relative absolute error. As a result, it is found that the proposed ERNN-EC method accomplishes accuracy of 95.2%, precision of 91%, recall of 85%, F1-score of 83.4%, and RAE of 41.6%. (shrink)

Speech perception has been a very productive and important area in psycholinguistics. In this review easy, I discuss Cutler's new book on native language listening. Cutler argues for a theory of speech perception, where all speech perception is accomplished by competence in native speech. I review this book and attempt to situate its main contributions in the broader context of cognitive science.

I think, from the standpoint of present experience, one can fairly start by saying that all experience is lived embodied experience, though it is clear that such a statement, if wholly unqualified, would mean a commitment of extensive implications. 1 Some of these implications I will briefly try to spell out toward the end of this essay. I don’t say our body sets limits to how far our imagination can really go, for clearly, if our imagination were wholly controlled by (...) our body as presented to us, dreams, for example, would not be possible. 2 But dreams are not only possible, they are a matter of everyday experience. Nay, even the limits of imagination do not determine the limits of possibility. .. (shrink)

Scholarly disquisitions on Nyāya(-Vaiśeṣika) philosophy in the English language generally agree in calling it “metaphysical realism” or simply “realism.” Metaphysical realism or realism as understood in the West is the doctrine that (1) substances (particulars)/things and events exist independently of the knowing/thinking mind, and that (2) they exemplify properties/qualities and enter into relations—in short, universals—independently of the concepts by which we know them and, Nyāya would add, even of the language with which we describe them. This mind-independent world is supposed (...) to be something correspondence with which renders our particular beliefs/cognitions determinately true or false. Thus, realism, in all .. (shrink)

The present paper entitled "Subaltern Language Games and Political Conditions: A Perspective on Applied Philosophy" attempts to streamline Wittgensteinian language games and political conditions. The expression `subaltern ` stands for the meaning as given in the concise oxford dictionary, that is, `of inferior rank`. Subaltern language game is the game of marginalized people. Language game is meaningful in the context of social and political relationship. My contention is that technical or symbolic language is an instrument to serve the end of (...) the affluent class. I think that any social and political change requires change in languagegame. By applied philosophy, I mean that philosophical theories are applicable in concrete human situation. In this sense, I have considered Wittgenstein as an applied philosopher because he holds that words are dead but assume life when it is used or applied in the concrete life situation. In order to make society free from exploitation and reduce inequality, we have to change the prevailing language game. The language game which I am proposing may be called as the "Subaltern Language Game". I have tried to understand Wittgenstein's language game in the light of Derrida's theory of deconstruction. The ordinary languagephilosophy as expounded in` Philosophical Investigation` deconstructs `technical language philosophy' of `Tractatus` because technical language gives an abstract system of symbols and lacks blood and flesh of lifeworld. My contention is that language game is inseparable from socio-political structure. As a matter of fact language game is the expression of forms of life. The language game of the affluent and the ruling class is different from the language game of the poor and downtrodden. The language game of one ethnic group is different from the language game of another ethnic group. The language game of the white people is different from the language game of the black. In Indian context, the language game of the upper caste is different from the language game of the lower caste. The possibility of inequality due to linguistic advantages of privileged class is a fact and not a fantasy. In order to develop linguistic capacity, it requires socio-political and socio-cultural mechanism. The social inequality due to linguistic handicap of individual can be lessened by a process of change in values. This process of change in value system is called culturalisation or sanskritisation. It can be helpful in changing the use of language and its meaning. Thus, in moving from theory to practice, philosophers work to change these words and rules for those philosophers who are trying to do applied philosophy. The language game of the applied philosopher should be fashioned in accordance with socio-political realities. It is not plausible to do applied philosophy with outdated mode of philosophising.

As a result, the ethical committees have encountered a sudden inflow of a large number of trial proposals (...) that have placed them under pressure. Although ethical committees play a vital role in protecting patient safety and preserving research integrity, they need to make sure the efficiency and integrity of review are preserved and the standards of review are not relaxed. Thus, the participants’ dignity is well guarded while keeping a close check on their safety. (shrink)

The present book intends to approach the problem of mind, meaning and consciousness from a non-naturalist or transcendental point of view. The naturalization of consciousness has reached a dead-end. There can be no proper solution to the problem of mind within the naturalist framework. This work intends to reverse this trend and bring back the long neglected transcendental theory laid down by Kant and Husserl in the West and Vedanta and Buddhism in India. The novelty of this approach lies in (...) how we can make an autonomous space for mind and meaning without denying its connection with the world. The transcendental theory does not disown the embodied nature of consciousness, but goes beyond the body in search of higher meanings and values. The scope of this work extends from mind and consciousness to the world and brings the world into the space of mind and meaning with a hope to enchant the world. The world needs to be retrieved from the stranglehold of scientism and naturalism. This book will dispel the illusion about naturalism which has gripped the minds of our generation. The researchers interested in the philosophy of mind and consciousness can benefit from this work. (shrink)

Long‐range correlation is a general class of coordination pattern found to be common to the intrinsic dynamics of complex systems, including human behavior. Balasubramaniam, Hove, and Médé investigate intrinsic dynamics in repeated finger movements, and they find that different measures of movement dynamics yield different long‐range correlations. Results shed light on the way that coordination patterns are expressed as a function of measurement context.

Mahatma Gandhi is regarded as an apostle of nonviolence. But his own thought prioritized truth as the final goal and nonviolence only as the preferred means to achieve the goal. Hence, it is of utmost importance to understand clearly what Gandhi meant by “truth.” Gandhi himself did not offer great help in communicating his concept of truth. He claimed, though, that it was easier for him to grasp truth as he conceived it and that he struggled to grasp nonviolence. Kishorlal (...) Mashruwala, an intellectually inclined close associate and follower of Gandhi wrote a book called Gandhi Vichar Dohan or Quintessence of Gandhi’s Thought in Gujarati. Mashruwala was a clear and systematic thinker and Gandhi approved of the book as accurate depiction of his own, Gandhi’s, thinking. The book has never been translated in English. The present work, Mahatma Gandhi’s Thought: Philosophy of Truth and Nonviolence, by Professor Ramesh N. Patel, is first in publishing relevant parts of that book. It clarifies the dual concept of truth that Gandhi developed and worked with. The concept sports highly original and innovative thinking that, at the same time, reflects an ethic that would challenge anyone to the extreme. Greatness of Gandhi is made obvious when it is realized that he lived this original concept of extremely challenging truth ethic fully through his life. The present work goes ahead to show how Gandhi’s concept of truth logically works as the prime source from which nonviolence and other Gandhian concepts are derived. It also presents Gandhi’s overall thought in a philosophically systematized manner. This is its unique feature compared to the enormous literature available on Gandhi which keeps painting him just as an apostle of nonviolence, focusing on his politically dramatic years. (shrink)

Adi Shankara is regarded as the greatest philosopher and spiritual leader in the very long history of India and one of the most influential thought leaders in world history. Estimates vary as to when he lived, with scholars placing it at 788-820 C.E. According to Shankara, there is only One Being, which is beyond language and thought because it is ultimate, infinite and all-pervasive. Being spiritual, this One Being is pure consciousness, unlike our normal consciousness which always requires subject-object duality. (...) The One Being is non-dual, being one without a second. Shankara’s concept of One Being strikes intuitively true to many, though it sounds narcissistic to a few. Shankara presents a strong rationale in its support and outlines a whole life path to reach the One Being in actual experience. As a concept One Being is a rational alternative to the traditional idea of God viewed as a divine person. Its spirituality is a constructive alternative to the atheist’s mere denial of God. This book, One Being, by Ramesh N. Patel, describes and explores Adi Shankara’s spiritual path and its supporting philosophy in an accessible and intelligible way for the serious modern reader interested in this challenging but highly rewarding subject. The reader is taken step by step through Shankara’s life, work, nature of knowledge, reality, life ethics, karma and details of the spiritual path of knowledge. In today's strife torn and bipolarized times, One Being is all the more relevant for its obvious potential as a spiritual healer bringing a harmonious message of unity in diversity. Ramesh N. Patel was Professor of Philosophy and Religion at Antioch College where he taught for twenty-five years, retiring in 2002. Since then he has been teaching voluntary classes in Bhagavad-gita, Upanishads, Vedic philosophy and Spiritual Studies. He is the author of Philosophy of the Gita and of Hinduism for Today. (shrink)

The chromosomes undergo a condensation‐decondensation cycle within the life cycle of mammalian cells. Chromosome condensation is a complex and critical event that is necessary for the equal distribution of genetic material between the two daughter cells. Although chromosome condensation‐decondensation and segregation is mechanistically complex, it proceeds with high fidelity during the eukaryotic cell division cycle. Cell fusion studies have indicated the presence of chromosome condensation factors in mammalian cells during mitosis. If extracts from mitotic cells are injected into immature oocytes (...) of Xenopus laevis, they induce meiotic maturation (i.e. germinal vesicle breakdown and chromosome condensation) within 2–3 hours. Recently, we showed that the maturation‐promoting activity of the mitotic cell extracts is inactivated by certain protein factors present in cells during the G1 period. The activity of the G1 factors coincides with the process of chromosome decondensation that begins at telophase and continues throughout the G1 period. These studies have revealed that the mitotic factors and the G1 factors play a pivotal role in the regulation of condensation and decondensation of chromosomes. Furthermore, our studies strongly suggest that nonhistone protein phosphorylation and dephosphorylation may mediate chromosome condensation and decondensation, respectively. (shrink)
