Digital holographic microscopy provides the ability to observe throughout a volume that is large compared its resolution without need actively refocus capture entire volume. This enables simultaneous observations of numbers small objects within such We have constructed microscope can 0.4 µm × 1.0 with submicrometer (in xy) and 2 z) for observation microorganisms minerals in liquid environments ...

Early repair of complete collateral ligament tears restores joint alignment, stability, and full passive range of motion.

This study targets the behavior of shear buildings equipped with tuned liquid column dampers (TLCD) which attenuate dynamic load-induced vibrations. TLCDs are a passive damping system used in tall buildings. This kind of damper has proven to be very efficient, being an excellent alternative to mass dampers. A dynamic analysis of the structure-damper system was made using the software DynaPy, de...

The vestibular sensory apparatus and associated vestibular nuclei are generally thought to encode head-in-space motion. Angular head-in-space velocity is detected by vestibular hair cells that are located within the semicircular canals of the inner ear. In turn, the afferent fibers of the vestibular nerve project to neurons in the vestibular nuclei, which, in head-restrained animals, similarly ...

Wilk, Macrina, and Fleisig, et al. have recently published a fourth study in a series of prospective cohort studies examining the relationship between shoulder passive range of motion and risk of injury in professional baseball players over the course of 8 competitive seasons. A total of 296 pitchers were evaluated each year starting in 2005 for passive range of motion in both dominant and non-...

Although second-order motion may be detected by early and automatic mechanisms, some models suggest that perceiving second-order motion requires higher-order processes, such as feature or attentive tracking. These types of attentionally mediated mechanisms could explain the motion aftereffect (MAE) perceived in dynamic displays after adapting to second-order motion. Here we tested whether there...

In the context of industrial engineering, the predetermined time systems (PTS) play an important role in workplaces because inefficiencies are found in assembly processes that require manual manipulations. In this study, an approach is proposed with the aim to analyze time and motions in a manual process using a capture motion system embedded to a virtual environment. Capture motion system trac...

In normal vision our gaze leaps from detail to detail, resulting in rapid image motion across the retina. Yet we are unaware of such motion, a phenomenon known as saccadic suppression. We recorded neural activity in the middle temporal and middle superior temporal cortical areas during saccades and identical image motion under passive viewing conditions. Some neurons were selectively silenced d...
