PURPOSE In the literature, immunohistochemistry on cross sections is the main technique used to study protein expression in corneal endothelial cells (ECs), even though this method allows visualization of few ECs, without clear subcellular localization, and is subject to the staining artifacts frequently encountered at tissue borders. We previously proposed several protocols, using fixation in ...

Since operating room departments are among the costliest resources at a hospital, much attention is devoted to maximize their utilization. Operating room activities are however notoriously hard to plan in advance. This has to do with the unpredictable, problem-solving nature of the work and that the work is carried out by a multidisciplinary team of health personnel, members of which also have ...

Sensing bioelectrical signals is of great significance to understand human disease. Reliable bioelectronic interface the guarantee high-quality signals. The unique electrochemical property and mixed ionic electrical conductivity poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) make it an ideal material for skin/tissue–electronic interface. However, pristine PEDOT:PSS-based de...

New helmet-mounted devices (such as night-vision goggles, laser eye protection, etc.) have created new safety hazards for pilots during ejection or high G maneuvering. In order to prevent the resulting head/neck injuries, this study extends the air-bag protection system developed for ground vehicles to a neck mounted system for aircrew personnel. Results, carried out by computer biodynamic simu...

The problem of impact dynamics of space robotic systems that consist of a rigid manipulator supported by a flexible deployable structure is addressed. Due to joint back-drivability and the dynamic coupling between the manipulator and its supporting structure, unknown motion of the system occurs after it makes impulsive contact with the environment. A method that uses the system's dynamic model ...

In this study, we consider a point-to-point motion of a flexible arm mounted on a flexible base, composed of a slide rail and helical extension springs, and then propose a trajectory planning method for reducing residual vibrations. The Lagrangian approach, in conjunction with the assumed mode method, is applied to derive the equations of motion of the system. In order to accurately construct t...

In the detection of moving objects from vision sources one usually assumes that the scene has been captured by stationary cameras. In case of backing up a vehicle, however, the camera mounted on the vehicle moves according to the vehicle's movement, resulting in ego-motions on the background. This results in mixed motion in the scene, and makes it difficult to distinguish between the target obj...

With the introduction of a new head-mounted displays models on the consumer market, the interest to those devices raised dramatically in the recent past. Although only a few wireless head-mounted display models are available today, there is a certain range of applications where those are required. Existing solutions that allow using conventional head-mounted displays for such applications wirel...
