A Comparative Study Between a Large Screen and an HMD Using Wind Representations in Virtual Reality.

In this article, we investigated the representation of wind in urban spaces through computational fluid dynamics simulations in virtual environments (VE). We compared wind perception (force and direction) as well as the sense of presence and embodiment in VE using different display technologies: head-mounted displays (HMD) and large screens, with or without an avatar. The tactile display was found to be most effective for detecting wind characteristics and enhancing presence and embodiment in virtual scenes, regardless of display type.

Human papillomavirus types in cases of squamous cell carcinoma of head and neck in Colombia.

Unlabelled: Estimating the type-specific prevalence of human papillomavirus (HPV) in head and neck cancer (HNSCC) is helpful in predicting the impact of HPV immunization.

Objective: To estimate the overall prevalence, and gender and age-specific prevalence of HPV in HNSCC.

Method: This cross sectional retrospective study was carried out in four pathology laboratories of Medellin, Colombia.
