We investigated how the nervous system processes ambiguous cues from the otolith organs by measuring roll tilt perception elicited by two motion paradigms. In one paradigm (tilt), eight subjects were sinusoidally tilted in roll with the axis of rotation near ear level. Stimulus frequencies ranged from 0.005 to 0.7 Hz, and the peak amplitude of tilt was 20 degrees . During this paradigm, subject...

UNLABELLED Although the presence of patellar tilt usually implies a tight lateral retinaculum and unhealthy pressure distributions within the patellar cartilage, it is possible for the bony portion of the patella to appear tilted while the articular cartilage is in fact fully congruous in a medial-lateral direction. We call this "congruous tilt." In such cases, a patient may not suffer from an ...

BACKGROUND Syncope is an important and common clinical condition, and the neurally mediated syncope is the most frequent type of syncope. Tilt testing is considered as a first-line diagnostic test. MATERIALS AND METHODS We conducted the conventional and modified tilt test on 200 subjects in the age range of 5-20 years. In conventional protocol, the patient was tilted for up to 15 min without ...

Large scale changes to lipid bilayer shapes are well represented by the Helfrich model. However, there are membrane processes that take place at smaller length scales that this model cannot address. In this work, we present a one-dimensional continuum model that captures the mechanics of the lipid bilayer membrane at the length scale of the lipids themselves. The model is developed using the Co...

The tilt and decentration of intraocular lens (IOL) result in defocussing, astigmatism, and wavefront aberration after operation. The objective is to give a method to estimate the tilt and decentration of IOL more accurately. Based on AS-OCT images of twelve eyes from eight cases with subluxation lens after operation, we fitted spherical equation to the data obtained from the images of the ante...

Introduction The reinforced concrete tilt-up building is the most popular form of light industrial and low-rise commercial construction in the Western United States and is a significant portion of new construction nationwide. This popularity is primarily driven by the construction speed and economical nature of tilt-up construction. Architectural acceptance has become more widespread as tilt-up...

potential fields are due to complex distribution of sources related to susceptibility and mass density variations for magnetic and gravity field respectively. in researching the lateral heterogeneous of different geological bodies, in particular their edge location potential field has some advantages. we mainly refer to linear features such as fault, folding axis, dyke, trend and border of the ...
