The aim of this study was to test the efficacy of a mood-induction procedure in a Virtual Reality (VR-MIP) environment for inducing relaxation and generating sense of presence, and to test whether the stimulation of the senses of touch and smell improves the efficacy of this VR-MIP. A controlled study was carried out with four experimental conditions. All of them included the VRMIP to induce re...

Feeling deeply connected to yourself and your body creates a richer experience of presence in a virtual world, even when your body is sitting in a chair wearing VR googles. We call this embodied presence. Connection to the self and body (paying attention to present-moment sensations and feelings) enhances the sense of self and the sense of presence, regardless of whether you are in the natural ...

Virtual reality systems have reached a certain level of maturity in terms of visual and aural quality, but the sense of presence also requires believably behaving environment. A new field of adding intelligence into virtual environments is emerging. We describe shortly the field of virtual reality, and how AI can be applied there. We outline the possibilities of using AI to enhance existing app...

The present paper is a review of the role of individual factors in Spatial Presence. If Spatial Presence is a subjective mental phenomenon psychological factors must have an important role on it. Our review shows that, even though many authors claim about the need for a better understanding about this relation, empirical evidence is still very limited. Personality-related factors as absorption,...

Perovskite solar cells have rapidly risen to the forefront of emerging photovoltaic technologies, exhibiting rapidly rising efficiencies. This is likely to continue to rise, but in the development of these solar cells there are unusual characteristics that have arisen, specifically an anomalous hysteresis in the current-voltage curves. We identify this phenomenon and show some examples of facto...

Congenital anomalies of the coronary arteries can be divided into two broad categories: those that alter myocardial perfusion and those that do not. In coronary anomalies not altering myocardial perfusion, the coronary arteries originate from the aorta, but their origins are in unusual positions. Although myocardial perfusion is normal, the angiographer may have trouble locating them. Patients ...

It is shown how Weyl’s geometry and Mach’s Holographic principle furnishes both the magnitude and sign (towards the sun) of the Pioneer anomalous acceleration aP ∼ −c/RHubble firstly observed by Anderson et al. Weyl’s Geometry can account for both the origins and the value of the observed vacuum energy density (dark energy). The source of dark energy is just the dilaton-like Jordan-Brans-Dicke ...

Sudden cardiac death (SCD) refers to death after an unexpected sudden cardiac arrest in a patient with or without known structural heart disease. The incidence of SCD in the United States ranges from 300 000 to 460 000 events per year, depending on the criteria for SCD used for surveillance. SCD results from a complex interaction between preexisting cardiac substrates, either structural or gene...

Recent studies of single-atom catalysts open up the prospect of designing exceptionally active and environmentally efficient chemical processes. The stability and durability of such catalysts is governed by the strength with which the atoms are bound to their support and their diffusive behaviour. Here we use aberration-corrected STEM to image the diffusion of single copper adatoms on graphene ...
