Recently, according to the advanced hardware technology, the price of sensors in HMD (Head Mounted Display) is getting cheaper and calculation speed in smartphone is fast enough to express a plausible virtual reality. Users wear the HMD device on their head and it shows the virtual scenes in front of users. Users can enjoy a wide display without any restrictions in space. Based on this device, ...

Background & Aims: Forward head posture deformity is a disorder in head weight balance condition leading to some alterations in cervical muscles, strength. This research aimed to determine the strength of deep and superficial cervical flexor muscles in female students with forward head posture compared to the normal group. Methods: From the total of 724 female students in Shahid Bahonar Univers...

The 3-amino-2-methylpyridine derivative 1 was identified as ligand of the BAZ2B bromodomain by automatic docking of nearly 500 compounds, selected on the basis of previous fragment hits. Hit expansion by two in silico approaches, pharmacophore search followed by docking, and substructure search resulted in five additional ligands. The predicted binding mode of the six 3-amino-2-methylpyridine d...

BACKGROUND Mammalian sperms are activated in the oviduct. This process, which involves extensive sperm surface remodelling, is required for fertilization and can be mimicked under in vitro fertilization conditions (IVF). METHODOLOGY/PRINCIPAL FINDINGS Here we demonstrate that such treatments caused stable docking and priming of the acrosome membrane to the apical sperm head surface without th...

We introduce a novel method for selecting and controlling smart appliances in physical spaces through a head-worn computing device with near-eye display and wireless communication. We augment a commercial wearable computing device, Google Glass, with a narrow-beam IR emitter for this purpose. This configuration yields a usable beam width of 2 to 4 feet (60 to 120cm) for targeting at room scale....

In this paper, a design procedure for mono-anchor head anchoring 2360 MPa high-strength steel strand is proposed. The performance criteria of the existing anchor based on PTI (Post-Tensioning Institute) have been reorganized so that they can be evaluated plastic hoop strain appearing at top wedge hole. order to does not exceed permissible standard, stress and deformation mechanisms were investi...

We propose a new metric, the 0-metric, that quantifies how a user is allocating control across multiple degreesof-freedom (dofs) while performing a docking task using an input device. The development of the 0-metric is based on two previous metrics from the literature, integrality [1] and inefficiency [2]. Integrality is a measurement in the time dimension only, and says nothing about the magni...
