“…A more elaborated model comprises a continuous measurment as a series of instantaneous measurements with the interval between them tending to zero [22]. Nevertheless, this is a controversial issue, but the work in the direction of Paul and Penning traps [21] could be, in a near future, a way to perform this kind of experiments [23].…”

Dedicated to Heinz Dehnen in honour of his 65 th birthday.In this work we obtain a family of quantum nondemolition variables for the case of a particle moving in an inhomogeneous gravitational field. Afterwards, we calculate the corresponding propagator, and deduce the probabilities associated with the possible measurement outputs. The comparison, with the case in which the position is being monitored, will allow us to find the differences with respect to the case of a quantum demolition measuring process. *

“…Another important application of radiation pressure is laser cooling. With multiple counter-propagating laser beams, the target particle will receive a force opposite to its direction due to Doppler effect, so that the particle motion is slowed, which means the temperature decreases [13,14]. Further research which combined magnetic field and radiation pressure could cool the atom down to micro or even nano Kal [15].…”

In this paper, radiation pressure induced deformation of a series of thin aluminum reflectors is analyzed theoretically and experimentally. Theory of quantum mechanics and material mechanics are applied in 2D simulations and exhibits good coordination with experiment results. The original laser source used in the experiment is Gauss-distributed and has been shaped and expanded, resulting in the flattened light to avoid over heating or even ablation of the irradiated reflector, which can also bring a major deformation. The aluminum reflectors are fabricated by a high precision machine tool into a thickness of 100, 200, 300 μm with a surface roughness of 8 nm in Ra, and then coated with high-reflective coatings and mounted on a thick 3D printing base made of polylactic acid (PLA). In the experimental process, a vacuum chamber is employed to distinguish the effect of thermal convection. The results show that radiation pressure induced deformation has an obvious negative correlation with the reflector thickness. The time-deformation curve of the reflector reaches 2.4 μm peak negative displacement at most the moment laser beam is acting when under vacuum circumstance, and soon raises up to over 12 μm positive displacement if the reflector is continuously irradiated. Subsequent analysis shows that such negative displacement is induced by radiation pressure and the positive displacement is caused by thermal expansion of the PLA base.

“…Few studies address the influence of alcohol on emotional processing using ERP techniques. Orozco and colleagues [122] investigated the role of alcohol on ERP responses to emotional faces. It was found that, following alcohol ingestion male subjects had decreased late positive (P450) amplitudes to male happy faces as compared to placebo.…”

[…] Social drinking, for most people, is an inseparable part of every-day life. Alcohol is used and abused for its ability to modify emotional states, and more precisely, to reduce anxiety [1], [2]. It is therefore essential to study the effects of inebriation in healthy, non-dependent individuals, given the frequency of abuse and binge drinking. A better understanding of the neural underpinnings of alcohol consumption could have a number of social implications, including the origin of the inebriation-induced aggressiveness, the tendency to abuse and the driving or work-related hazards [3]. More precisely, this study aimed to answer to the following questions: - How acute alcohol intake affects the human brain responses to affective pictures? - Is the effect of alcohol emotion-specific or is it the same for all kinds of emotion-eliciting images? - Is the brain functional organization at rest modulated by inebriation? - What are the similarities and the differences between the EEG and MEG studies conducted? In a second level, there has been an effort to design the optimal experimental procedure to examine as accurately as possible the multi-factorial issue of inebriation effects on the human brain. Regarding the analysis of the recordings, the standard analysis techniques on sensor levels were first applied, and then, more advanced techniques, such as cortical source estimation and functional connectivity were used to examine whether any additional information is provided.
