Byintroducing/using the concept of information, it is shown that this concept includes two facets, one of themreferring to the common communications and another one referring to a hidden/structuring matter-relatedinformation, effectively acting in the human body and in the living systems, which determines the dynamicinter-change of information between specific structures of the organism by electric/electronic/chemical agents andgenetic/epigenetic processes. It is shown that the maintenance of body, permanently and obligatory depending onthe external matter (foods, air, water) resources, needed to provide both the structuring/restructuring basic materialand energy, determines the necessary existence of an info-managing system, administrating the internalmechano-chemical/physical processes. As a natural consequence, such a system should organize and assure ownsurvival by an effective informational operability to detect the external food resources, to select the appropriateinterest information and to decide as a function of circumstances. One important component in such aninformational system is memory, allowing to dispose of the reference informational data for analysis/comparisonand the selection between good and bad binary possible decisions. The memory receives and stores thereforesignals from external reality and from the body itself, referring to the emotional reaction, digestion status, creation,and inherited predilections, within specific info-neural communication circuits between the brain and bodyexecution/sensitive organs, the human body appearing as an integrated info-matter self-managed dynamic system.The specific body components memorize information with different degrees of info-integration: short/long-termintegration, emotive/action reaction, info-abilities, culminating with the integration in the chromosomal structuresby epigenetic processes. The new acquired information is transgenerationally transmissible, and is manifested asnew traits, showing the adaptation capability of the human and close relation between mind and body. Analyzingthe results of such a mind-body informational model in comparison with the earlier assumed/proposed/assertedarchaic, Greek and Occidental philosophies, which represent only partial aspects of this relation, it is shown thatthis informational model, elaborated in terms of information on the basis of scientific reasons and arguments,constitutes a general, realist, and coherent model of the mind-body relation, able to integrate and/or explain most ofthe others.展开更多

In an affect-object generative inference and regulation (AGIR) model, we propose that functional dynamics between two systems, the affect-object thought generation system and the cognitive control system, can guide an individual to achieve homeostasis within self and harmonious relationships with others. We used Neurosynth (www.neurosynth.org), an automated meta-analysis database, to identify potential brain substrates underlying the key components in the AGIR model. Based on the findings, some brain regions are implicated as the key cortical substrates in this model, corroborating our central hypothesis that a hallmark of mind-body wellbeing can be characterized as a low-frequency anti-correlantion between 1) the cognitive control system including the dorsal anterior/middle cingulate cortex, and 2) the affect-object thought generation system including the ventromedial prefrontal cortex and posterior cingulate cortex. MBB provides an efficient strategy for responding to and dissolving a fundamental problem that impairs mind-body wellbeing, i.e., unrealistic identity-grasping consisting of self-centered embodied expectations of self and others. We demonstrated how theoretical and applied work could be integrated by drawing evidence from the neuroscience literature to support the AGIR model, and then we applied the AGIR model to elucidate how MBB might work.展开更多

Moreover, it will analyze the dichotomy that has historically emerged and its implications. Human beings have had different conceptions about what is natural and what is non-natural throughout their history. Before Modernity we did not conceive nature as being a different ontological reality, we did not perceive it as being separated from us. After modernity everything changed, and we began to see nature as a mere object. Nature became, then, a representation, like a painting on a wall. Our contemporary world vision, Weltanschauung, was formed mainly during the 16th and 17th centuries. There was, at that time, a considerable change in the way we perceived and described the world. This new mentality and this new form of representing the cosmos provided the basis for our new way of thinking. They were the substrate upon which our modern paradigm was erected. The world's conversion in an image only became a reality thanks to technology. But this change happened only because of the paradigm shift originated in the 17th century. Technique always has been a way to articulate how (and what) we think. With the Greek, technique (technd) was, at first, an extension of the physis. Thus, the technique was a way of being instead of a way of thinking. After the paradigm shift in the 17th century (a metaphysical change, in the very way we connected to the world), the human being left his former place. Perhaps would be even better if we talked about nature and culture as being as a hybrid. What, at the source, was natural, through the flows of production and consumption, undergoes transformations and becomes something that is not natural anymore but, at the same time, not completely artificial either. Our world, once divided between the social and the natural, becomes a space where a constant process, a continuous flow, is constantly happening. From that dichotomy between something good and something bad arises a dialectic, in which we no longer can see any division whatsoever.展开更多

And further we believe that quantum language is the only scientifically successful theory in dualistic idealism. If this turn is regarded as progress in the history of western philosophy (i.e., if “philosophical progress” is defined by “approaching to quantum language”), we should study the linguistic mind-body problem more than the epistemological mind-body problem. In this paper, we show that to solve the mind-body problem and to propose “measurement axiom” in quantum language are equivalent. Since our approach is always within dualistic idealism, we believe that our linguistic answer is the only true solution to the mind-body problem.展开更多

Increase in attention, relaxation and parasympathetic system activity is believed to enhance the shooting performance of archers during competition. This pilot study aims to investigate the effects of single-dose of Tai Chi practice on archer’s performance and the feasibility of an investigation protocol under a competition scenario. Methods: This was a randomized controlled trial (RCT) with a crossover study design. Pre- and post-intervention measurements were conducted to evaluate the effects of Tai Chi practice on the archer’s autonomic nervous system activity, attention and relaxation through electroencephalography investigation, and shooting performance when compared with stretching as control. Results: The protocol of the study was found to be feasible during a competition setting. No significant difference was detected in the outcome measures under the two intervention conditions. Participants after practicing Tai Chi were found to improve significantly in their shooting performance (p = 0.021). Conclusion: This pilot study showed that a real-time measurement of autonomic nervous system and brain wave activities in the competition field was feasible and it did not hinder the archers’ performance. There was a significant improvement observed in the shooting performance of archers after Tai Chi practice when compared with baseline. The findings of this pilot study provide the basis for the conduction of a larger RCT study to examine the potential beneficial effects of Tai Chi practice on archers.展开更多

Here is the first attempt to use asymptotic approach and nonlinear concepts to address the paradoxes. Among the paradoxes, two of the most famous ones are Zeno’s Room Walk and Zeno’s Achilles. Lie Tsu’s pole halving dichotomy is also discussed in relation to these paradoxes. These paradoxes are first-order nonlinear phenomena, and we expressed them with the concepts of linear and nonlinear variables. In the new nonlinear concepts, variables are classified as either linear or nonlinear. Changes in linear variables are simple changes, while changes in nonlinear variables are nonlinear changes relative to their asymptotes. Continuous asymptotic curves are used to describe and derive the equations for expressing the relationship between two variables. For example, in Zeno’s Room Walk, the equations and curves for a person to walk from the initial wall towards the other wall are different from the equations and curves for a person to walk from the other wall towards the initial wall. One walk has a convex asymptotic curve with a nonlinear equation having two asymptotes, while the other walk has a concave asymptotic curve with a nonlinear equation having a finite starting number and a bottom asymptote. Interestingly, they have the same straight-line expression in a proportionality graph. The Appendix of this discussion includes an example of a second-order nonlinear phenomenon. .展开更多

This interconnection can be viewed as harmonic control of independent sub-systems. Linear interconnections and a class of input and output interconnections are considered in this paper. The effects of input and output interconnections are shown through a permutation matrix. Frequency domain and linear matrix inequality (LMI) conditions of dichotomy of interconnected pendulum-like systems are derived. It is shown that global properties of two coupled systems can be changed significantly through interconnections. Examples are given to illustrate the results.展开更多

文摘The property of dichotomy of interconnected second-order pendulum-like systems with multiple equilibria is investigated. This interconnection can be viewed as harmonic control of independent sub-systems. Linear interconnections and a class of input and output interconnections are considered in this paper. The effects of input and output interconnections are shown through a permutation matrix. Frequency domain and linear matrix inequality (LMI) conditions of dichotomy of interconnected pendulum-like systems are derived. It is shown that global properties of two coupled systems can be changed significantly through interconnections. Examples are given to illustrate the results.
