Setting the record straight for fossil flying fishes versus non-flying ones: a comment

Setting the record straight for fossil flying fishes versus non-flying ones: a comment on Xu et al. (2015).

A new stem-neopterygian fish from the Middle Triassic of China shows the earliest over-water gliding strategy of the vertebrates.

Flying fishes are extraordinary aquatic vertebrates capable of gliding great distances over water by exploiting their enlarged pectoral fins and asymmetrical caudal fin. Some 50 species of extant flying fishes are classified in the Exocoetidae (Neopterygii: Teleostei), which have a fossil record no older than the Eocene. The Thoracopteridae is the only pre-Cenozoic group of non-teleosts that sh...

Non-Pharmacologic Treatments for Fear of Flying

The purpose of the present survey was to review the important Non-pharmacologic treatments for fear of flying up to the present. This study is in the same way as some studies. Accordingly, some Non-pharmacologic treatments for fear of flying were assessed through this systematic review article. The general conclusion from the information provided by the  former studies, shows that a growing num...

Efficacy of virtual reality exposure therapy in reducing anxiety symptoms in Iranian individuals with flying phobia

Objective: Virtual reality exposure has recently emerged as an innovative tool for exposure therapy in the treatment of fear of flying. Fear of flying, a key component of which is anxiety, often remains uncured if no intervention procedures are employed. Not to point to the fact that about 10 to 25 percent of all the individuals experience anxiety and ‌that causes the individual entirely to avo...

Differential Flatness Method Based on Pre-set Guidance and Control Subsystem Design for a Surface to Surface Flying Vehicle (TECHNICAL NOTE)

The purpose of this paper is to design a guidance and control system and evaluate the performance of a sample surface‑to‑surface flying object based on preset guidance with a new prospective. In this study, the main presented idea is usage of unique property of governor differential equations in order to design and develop a controlled system. Thereupon a set of system output variables have bee...
