VR Serious Games and Negative Schizophrenia Symptoms
Schizophrenia is a chronic brain disorder that affects 1 in every 300 people worldwide. VR is an interesting tool that has started to be used in remediation therapies. Although it is typically used as an exposure technique for specific phobias, VR has been applied, with encouraging results, to the study and treatment of schizophrenia. It can offer the potential for a significant therapeutic benefit, since patients are more willing to enter challenging situations and experiment with alternative ways of responding.

VR and Virtual Shopping Stores
A virtual reality (VR) platform generates a computer-simulated environment that is fostered and assisted by the head-mounted display (HMD), which utilizes a manipulator in an immersive environment. VR is broadly used for cognitive purposes in various industries in the fields of engineering, architecture, and medicine. Software makers are also in the perspective of introducing virtual stores where consumers can enter the virtual stores and visualize the dimensions and usability of an item prior to purchasing it. A virtual shopping store is a computer-simulated store where a handler can envisage, feel, and interact with the products and items in the store. Implementation of the virtual store can be a breakthrough in the e-commerce market. Other famous terms for virtual stores are cybernetic stores and computer-simulated 3D spatial stores. In current e-commerce stores, one of the recorded fraudulent activities is the delivery of an ordered item different from that itemized in the e-commerce store. Needless to say, a virtual store can spark a revolution in the e-commerce industry by not only altering the way of shopping but also by making it secure.

VR and Natural Heritage
Caves can be considered as features of the landscape that have been formatted through a long period and are signs of the past climatological conditions, of prehistoric animal and human inhabitation, and provide habitat for species. The sustainability and protection of cave heritage have been recently discussed mainly because over-tourism has been proven to have negative side effects on the preservation of the heritage site. Technology today has provided widely adopted inexpensive technical means to support immersive visiting experiences to sites of heritage interest that could support their valorization and sustainability in forms more friendly to the site. An alternative visiting approach is explored through a use case applied to the Alistrati cave near Serres, Greece, where a VR tour guide can support immersive visiting experiences to the heritage site. By employing means of digital preservation of heritage sites the VR solution aspires to offer immersive close to reality engaging visiting experiences.

Voyeurism
Voyeurism is the sexual interest in or practice of watching other people engaged in intimate behaviors, such as undressing, sexual activity, or other actions usually considered to be of a private nature. The term comes from the French voir which means "to see". A male voyeur is commonly labelled as "Peeping Tom" or a "Jags", a term which originates from the Lady Godiva legend. However, that term is usually applied to a male who observes somebody secretly and, generally, not in a public space. The American Psychiatric Association has classified certain voyeuristic fantasies, urges and behaviour patterns as a paraphilia in the Diagnostic and Statistical Manual (DSM-IV) if the person has acted on these urges, or the sexual urges or fantasies cause marked distress or interpersonal difficulty. It is described as a disorder of sexual preference in the ICD-10. The DSM-IV defines voyeurism as the act of looking at "unsuspecting individuals, usually strangers, who are naked, in the process of disrobing, or engaging in sexual activity". The diagnosis would not be given to people who experience typical sexual arousal simply by seeing nudity or sexual activity. In order to be diagnosed with voyeuristic disorder the symptoms must persist for over six months and the person in question must be over the age of 18.

Voxelisation Algorithms
Voxel-based data structures, algorithms, frameworks, and interfaces have been used in computer graphics and many other applications for decades. There is a general necessity to seek adequate digital representations, such as voxels, that would secure unified data structures, multi-resolution options, robust validation procedures and flexible algorithms for different 3D tasks.

Voting-Based Leader-Election Scheme in Lead-Follow UAV Swarm
The recent advances in unmanned aerial vehicles (UAVs) enormously improve their utility and expand their application scope. The UAV and swarm implementation further prevail in Smart City practices with the aid of edge computing and urban Internet of Things. The lead–follow formation in UAV swarm is an important organization means and has been adopted in diverse exercises, for its efficiency and ease of control. The reliability of centralization makes the entire swarm system in risk of collapse and instability, if a fatal fault incident happens in the leader. Researchers propose a voting-based leader election scheme inspired by the Raft method in distributed computation consensus to build a mechanism helping the distributed swarm recover from possible failures.

Vostok 3
Vostok 3 (Russian: Восток-3, Orient 3 or East 3) was a spaceflight of the Soviet space program intended to determine the ability of the human body to function in conditions of weightlessness and test the endurance of the Vostok 3KA spacecraft over longer flights. Cosmonaut Andriyan Nikolayev orbited the Earth 64 times over nearly four days in space, August 11–15, 1962, a feat which would not be matched by NASA until the Gemini program (1965–1966). Vostok 3 and Vostok 4 were launched a day apart on trajectories that brought the spacecraft within approximately 6.5 km (4.0 mi) of one another. The cosmonauts aboard the two capsules also communicated with each other via radio, the first ship-to-ship communications in space. These missions marked the first time that more than one crewed spacecraft was in orbit at the same time, giving Soviet mission controllers the opportunity to learn to manage this scenario.

Vortioxetine´s Effects on Sleep of Adolescent Major Depression
The relationship between depression and insomnia is bidirectional and both conditions need to be treated adequately, especially in a vulnerable neurodevelopmental stage of adolescence. Sleep disturbances in adolescents have been associated with a more severe clinical course of depression (i.e., suicidal behavior, worse psychosocial functioning, and risk of recurrence). Due to the rising incidence of both disorders, it is crucial to understand the underlying pathophysiology (e.g., disrupted neuroplasticity and neurotransmitter dysbalance), especially in the vulnerable adolescent age period characterized by developmental changes and sensitivity to endogenous and exogenous factors.
