BACKGROUND We studied the anomalous head postures (AHPs) of five monocular viewing patients and investigated the possible causes and the appropriate surgical strategies to correct each condition. METHODS Five patients with acquired visual loss in one eye and associated head tilt and/or turn were examined and treated for correcting the head posture according to the etiology of their respective...

A 200-kHz echosounder modified to digitize the envelope of the received echoes directly into a computer was used to measure the ex situ target strength ~TS! of live animals from the Hawaiian mesopelagic boundary community as a function of animal size, tilt and roll angle, and biological classification. Dorsal aspect TS ~in dB//1 m! at 200 kHz was related to the animal’s length: myctophid fish T...

Self-orientation perception relies on the integration of multiple sensory inputs which convey spatially-related visual and postural cues. In the present study, an experimental set-up was used to tilt the body and/or the visual scene to investigate how these postural and visual cues are integrated for self-tilt perception (the subjective sensation of being tilted). Participants were required to ...

sublingual nitroglycerin (tng) has been introduced as a promising provocative agent for tilt table testing, but it has not been compared directly with the standard isoproterenol (iso) infusion test previously. we tried to assess the diagnostic value and safety of tng tilt testing as compared with iso infusion in patients with unexplained syncope. tng and iso tilt tests were performed in two suc...

Iran has great potential in utilizing solar energy. In order to maximize the amount of absorbed solar radiation to absorber surfaces, the surfaces should be installed at a suitable angle slope to the horizon that is discussed in this article. The calculations performed in this study was done using MATLAB software. In this study, radiation received on the ground in 31 provincial capitals of the ...

This paper presents an information-driven audiovisual signal acquisition approach. This approach has several advantages: users are encouraged to assist in signal acquisition; available sensors are managed based on both signal characteristics and users’ suggestions. The problem formulation is consistent with many well-known empirical approaches widely used in previous systems and may provide ana...

ABSTRACT: The bearing capacity of shallow foundations is classically computed as the sum of three contributions, coming from the soil cohesion, the overburden pressure and the weight of the soil mass mobilized by the collapse mechanism. Each of these contributive terms is then multiplied by several special corrective factors that account for the effect of the shape, depth and tilt of the founda...

We have studied various ferroelectric liquid crystals to find the average molecular direction of the shortest axis in the perfectly unwound state by using tilted conoscopic measurements. We find that there exist two types of temperature dependencies of the biaxiality. Some materials exhibit increasing biaxiality while others show decreasing biaxiality with increasing temperature. The former sho...

Abstract Two dimensional quantum materials possessing Dirac cones in their spectrum are fascinating due to emergent low-energy fermions. In 8Pmmn borophene the cone is furthermore tilted, which a proxy for spacetime geometry, since future light-cone depends on underlying metric. Therefore it important understand microscopic origin of tilt. Here, based ab-initio calculations, we decipher atomist...
