In this paper, a fiber based Fabry-Perot interferometer is proposed and demonstrated for a non-contact displacement measurement. A piece of micro-prism which attached to the mechanical vibrator is served as the target reflector. Interference signal is generated from the superposition between the sensing beam and the reference beam within the sensing arm of the fiber sensor. This signal is then ...

When generating a saccade toward a moving target, the target displacement that occurs during the period spanning from its detection to the saccade end must be taken into account to accurately foveate the target and to initiate its pursuit. Previous studies have shown that these saccades are characterized by a lower peak velocity and a prolonged deceleration phase. In some cases, a second peak e...

24 When generating a saccade toward a moving target, the target displacement that 25 occurs during the period spanning from its detection to the saccade end must be taken 26 into account in order to accurately foveate the target and to initiate its pursuit. 27 Previous studies have shown that these saccades are characterized by a lower peak 28 velocity and a prolonged deceleration phase. In som...

This paper presents a pan-tilt-zoom (PTZ) camera-based displacement measurement system, specially based on the perspective distortion correction technique for the early detection of building destruction. The proposed PTZ-based vision system rotates the camera to monitor the specific targets from various distances and controls the zoom level of the lens for a constant field of view (FOV). The pr...

This paper describes the development of a unique fluorescence based DNA diagnostic assay that does not require labeling of the target sequence prior to analysis. The assay uses polyacrylamide hydrogel plugs immobilized in microfluidic channels, and is based on the displacement of a short sacrificial fluorescent-tagged indicator oligomer by a longer untagged target sequence as it is electrophore...

Real-world machine learning applications must be able to adapt to systematic changes in the data, e.g. a new subject or sensor displacement. This can be seen as a form of transfer learning, where the goal is to reuse the old (source) model by adapting the new (target) data. This is a challenging task, if no labels for the target data are available. Here, we propose to use the structure of the s...

Prior to an eye movement, attention is gradually shifted toward the point where the saccade will land. Our goal was to better understand the allocation of attention in an oculomotor capture paradigm for saccades that go straight to the eye movement target and for saccades that go to a distractor and are followed by corrective saccades to the target (i.e., involuntary saccades). We also sought t...

Saccadic eye movements and the adaptive control of their amplitudes were examined in patients with Wallenberg's lateral medullary syndrome. Half of the patients had permanent saccadic dysmetria. Their primary saccades had asymmetric amplitudes: those made in response to an ipsilateral target step (i.e. to the lesion side) tended to be hypermetric and saccades made in response to a contralateral...

In contrast to other functions which are suppressed during saccades, saccadic suppression of displacement (SSD--a decrease in sensitivity to visual displacements during saccades) has often been considered to be due to efferent processes rather than to visual masking. The aim of this study was to explicitly assess the importance of visual conditions in SSD. In two experiments, a small computer-g...

[18F]Fluoride for nucleophilic radiofluorination was recovered from target water by trapping on a fibrous anion exchange resin in the hydroxide form and subsequent displacement into wet methanolic K2CO3. Extraction into methanol facilitated rapid evaporation and resolubilization of the [18F]fluoride as an ion pair. The resin was first dried in situ and rehydrated with [18O]H2O to avoid isotopic...
