“…To reduce the visual-vestibular confl ict responsible for causing motion sickness, a galvanic vestibular stimulation is also used [12,20,49,63,64]. In this method, galvanic signals from electrodes placed close to the mastoid vestibular aff erents distraction built into an additional task as a method of increasing SD susceptibility and the eff ectiveness of SD training only.…”

Introduction: To improve the effectiveness of spatial disorientation (SD) training in a flight simulator, pilots are recommended to perform an additional task that induces a mental distraction. The presented study explored how the inclusion of an additional task that may enhance the effectiveness of SD training changes the severity of simulator sickness symptoms reported after exposure in the Gyro-IPT simulator. Methods: We compared the incidence of simulator sickness symptoms in pilots across four setups of flight scenarios (varying according to cognitive load distraction) collected during our previous studies. A total of 77 male military pilots (age 28.3±6.2) with flight experience (810.72 ±969.43 hours) were randomly assigned to one of four groups and then exposed to a 60-min long flight session (12 flight profiles, six involved an SD-conflict) with active control in the Gyro IPT simulator. In addition to the primary flying task, in three flight scenarios, pilots were asked to perform an additional visual (a change detection flicker task [CDFT]), auditory (an auditory N-back task [NBT]), or duration-discrimination task (DDT)). To measure simulator sickness symptoms, the Simulator Sickness Questionnaire (SSQ) was administered pre- and post-simulator exposure. Results: The severity of simulator sickness symptoms due to visual and motion cues did not significantly change when the pilot performed a non-sickening cognitive task (additional visual or auditory task). The total SSQ score and scores for nausea, oculomotor disturbance, and disorientation in the CDFT and DDT were slightly higher than in the control condition (flight without additional task). Despite the observed differences, according to the SSQ scoring criteria, the simulator sickness symptoms reported by the pilots were negligible. Conclusions: The additional tasks (CDFT, auditory NBT, or DDT) applied to improve the effectiveness of SD training in the Gyro-IPT simulator do not significantly change unwanted effects, such as simulator sickness.

“…A dark/bright switched movie (∼0.3 Hz) causes a feeling of carsickness. Low-frequency ocean waves makes people seasick on a ship, but fishermen and crew members will adapt to this wave frequency through long-term navigation . In general, high-frequency waves might enhance the ionic coherent resonance, and low-frequency waves might destroy the ionic coherent resonance.…”

Conspectus Life systems present ultralow energy consumption in high-efficiency energy conversion, information transmission, and biosynthesis. The total energy intake of the human body is about 2000 kcal/day to maintain all of our activities, which is comparable to a power of ∼100 W. The energy required for the brain to work is equivalent to ∼20 W, and the rest of the energy (∼80 W) is used for other activities. All in vivo biosyntheses take place only at body temperature, which is much lower than that of in vitro reactions. To achieve these ultralow energy-consumption processes, there should be a kind of ultralow-resistivity matter transport in nanochannels (e.g., ionic and molecular channels), in which the directional collective motion of ions or molecules is a necessary condition rather than traditional Newton diffusion. The directional collective motion of ions and molecules is considered to be ionic/molecular superfluidity. The driving force of ionic/molecular superfluidity formation requires two necessary conditions: (1) Ions or molecules are confined at a certain distance (e.g., approximately twice Debye length (2λD) for ions or twice the van der Waals equilibrium distance (2d 0) for molecules). (2) When the attractive potential energy (E 0) is stronger than the thermal noise (k B T c), ionic/molecular superfluidity can be formed. The concept of ionic/molecular superfluidity will promote the understanding of energy conversion with ultralow energy consumption in biological systems. The swing of an eel’s body generating electricity and cardiac resuscitation denote the conversion from mechanical energy to electrical energy, and mechanical modulation might result in a coherent resonance of ionic motion. The coherent resonance of Ca2+ in myocardium cells can induce a heartbeat, realizing the conversion from the electrical energy to the mechanical energy of a biological system. The macroscopic quantum state of ion channels is considered to be a carrier of neural information, and the environment field might play a significant role in regulating the macroscopic quantum states of various ion channels. In the biological ion channels system, the coupling of ion channels and their released photons might induce an environment wave which in turn regulates the ion oscillations in the channels to a coherent state. The states of decoherence and coherence might correspond to the states of sleep and action. We also demonstrated the decomposition of ATP to ADP released photons with a frequency of ∼34 THz, which could further drive DNA polymerization in the nanocavity of DNA polymerase. The photochemical (mid- and far-IR) reaction might be the driving force in high-efficiency biosynthesis. Quantized syntheses resonantly driven by multiple mid- and far-IR photons could be further designed in a tubular reactor with membranes of different microporous structures to achieve a high-efficiency synthesis with a low energy consumption. Finally, we point out that the Bose–Einstein condensate potentially widely exists. We expect that this...
