The “Rubber Hand Illusion” (RHI) is one of the most popular experimental paradigms to investigate this phenomenon. During this illusion, ownership of a rubber hand is temporarily induced. It was shown that external and continuous cooling of the palm enhanced the RHI, suggesting an association between altered the autonomic nervous system regulation and altered the sense of ownership of a specific limb. Purpose: To investigate whether artificially cooling the entire hand for a short period affects the magnitude of the illusion. Methods: Participants immersed their entire hand in cool, cold, or warm water for 1 min before the RHI procedure. Results: We found that cooling the entire hand enhanced the proprioceptive drift during the RHI but not the subjective feeling of ownership. In contrast, warming and intense cooling of the entire hand did not affect the RHI strength. Conclusion: Our results suggest that transient and moderate cooling of the entire hand was sufficient in enhancing the illusory disembodiment of one’s own hand.展开更多

Great change of society, as well as traditional values, gives an impact on the escapists. They feel mixed-up and perplexed about their lives and future. The conflicts among pursuit and disillusionment, past and present, tradition and modernity, material and spirit, ideal and reality make the escapists choose to build a wall to separate them from the real world. They become the souls drifting in the reality, without knowing their status in society or the meaning of life.展开更多

Since the maximal height in the one-dimensional universe must be where is the unit interval length and note that the topological mass (m) and topological dimension (D) where m = D = 5 are that of the largest unit sphere volume, we can conclude that the potential energy of classical mechanics translates to . Remembering that the kinetic energy is , then by the same logic we see that when m = 5 is replaced by for reasons which are explained in the main body of the present work. Adding both expressions together, we find Einstein’s maximal energy . As a general conclusion, we note that within high energy cosmology, the sharp distinction between potential energy and kinetic energy of classical mechanics is blurred on the cosmic scale. Apart of being an original contribution, the article presents an almost complete bibliography on the Cantorian-fractal spacetime theory.展开更多

However, only two-dimensional(2 D) thermal illusion devices are researched recently. According to this situation, our study focuses on three-dimensional(3 D) thermal illusion devices including shrinker(or invisible cloak),concentrator, amplifier, reshaper, and rotator with arbitrary shape in a general way. In this paper, the corresponding material parameters of thermal illusion devices mentioned above are derived based on the theory of transformation thermodynamics and the simulated results agree well with the theoretical derivations. In addition, the conventional invisible cloak just controls the temperature gradient rather than the temperature value which is more concerned in physical applications. Here,we find that the temperature value of the cloaked object can be controlled by adjusting the location of the original point of the coordinate system.展开更多

In comparison with the reported reciprocal invisibility cloaks, the material parameters of the device presented here are homogeneous, and the hiding of the target object does not require any “anti-object” at all,which dramatically breaks through the limitations of the “anti-object” design in previous reciprocal cloak design. Perfectly illusion effect is also found by reasonably setting the material parameters of the restored medium of the device, which can be used to confuse detection radars while hiding target objects. Last but not least, the proposed device has an open structure,which enables the target object enclosed by the device to perform material exchange and simplex transfer of information with the outside world through open channels. In other words, the proposed device has a reusable function, enabling stealth or phantom of new target objects without changing any parameters of the device.展开更多

Simulation results show that when an object is covered with the thermal illusion device, it will accurately perform the same temperature distribution signature as another object we have predetermined. Owing to the property of deceiving and interfering with the observer, the thermal illusion device can achieve generalized thermal stealth by using thermal metamaterials, which may have a potential application in military field.展开更多

However, that scenario can be revived with the modern findings of gravitational forces, coming from outside of the “luminous world”, tugging on our universe. These unexplained phenomena were: the redshift, the CMB, and Olbers’ paradox. All these can now be explained, as done in the present manuscript. 1) The observed redshift, which is commonly attributed to the Doppler effect, can also be explained as a gravitational redshift. Thus, the universe is not expanding, as has also been described in recent publications, thereby, making the “Big Bang” hypothesis unnecessary. 2) Gravitation is induced by matter, and at least some of the distant matter is expected to be luminous. That electro-magnetic emission is extremely redshifted, and thus perceived by us as CMB. CMB is not necessarily a historic remnant related to the “Big Bang”, rather it is the redshifted light, coming from extremely distant luminous matter. 3) According to Olbers’ paradox, the night sky is expected to be bright. The sky looks dark because the light coming from extremely faraway light sources, out of our visible universe, is extremely redshifted. Therefore it is perceived by us as CMB. As in the cosmological literature many problems with the “Big Bang” hypothesis have been described, where as the problems with the static universe model are resolved in the present manuscript, the static state scenario should be renovated.展开更多
