Spatial resolution in visual memory
Psychonomic Bulletin & Review, 2014Representations in visual short-term memory are considered to contain relatively elaborated information on object structure. Conversely, representations in earlier stages of the visual hierarchy are thought to be dominated by a sensory-based, feed-forward buildup of information.

Spatial Resolution in Digital Mammography
Investigative Radiology, 1993Digital acquisition systems currently available limit spatial resolution in digital mammography to roughly 0.1 mm/pixel. The objective of this study is to determine if high-quality mammography is possible at this resolution.The influence of spatial resolution on diagnostic quality was investigated by comparing observer performance on film to that on ...

High-Spatial-Resolution Geochronology
Elements, 2013High-spatial-resolution isotope analyses have revolutionised U–(Th–)Pb geochronology. These analyses can be done at scales of a few tens of microns or less using secondary ion mass spectrometry or laser ablation inductively coupled plasma mass spectrometry.

Spatial and temporal resolution in FMRI
2001Abstract Most functional MRI studies to date have used relatively low resolution, both in space and time, to interrogate brain function. Typically, an in-plane resolution of 3-4 mm is used, in conjunction with slice thicknesses of 5-10 mm.

Bubble sizing with a high spatial resolution
IEEE 1988 Ultrasonics Symposium Proceedings., 1990The authors propose a technique that allows them to size bubbles with the same accuracy as with the double-frequency method and to locate them with the same range resolution as with the pulsed Doppler velocimeter. They demonstrate that the signal scattered by the bubble insonified by a high-frequency pulsed ultrasonic field and a low-frequency pumping ...

Proceedings of IGARSS '93 - IEEE International Geoscience and Remote Sensing Symposium, 2002
This method consists of two parts: extraction of the high spatial resolution from high spatial resolution visible and near-infrared images, reconstruction of the high resolution image from a low resolution image using extracted high resolution spatial information.

IEEE Nuclear Science Symposium Conference Record, 2005, 2006
Pixellated detectors based on cadmium-zinc telluride (CZT) are a promising alternative to NaI-based SPECT cameras. The performance of either system is quantitatively described in terms of resolution and sensitivity. This investigation is based on an analytical model published earlier, describing SPECT collimators according to the NEMA definitions of ...

Asteroseismology with A Spatial Resolution
2000One of the main objectives of the detailed study of the spectra of excited modes in main sequence pulsating stars is the unique opportunity to apply, similar to helioseismology, the inverse techniques for investigation of a star’s inner structure. Numerous sets of detected and (ι,m,n) — identifiednormal nonradial modes is crucial for the application of

Effects of spatial configurations on the resolution of spatial working memory
Attention, Perception, & Psychophysics, 2014Recent research demonstrated that people represent spatial information configurally and preservation of configural cues at retrieval helps memory for spatial locations (Boduroğlu & Shah, Memory & Cognition, 37(8), 1120-1131 2009; Jiang, Olson, & Chun, Journal of Experimental Psychology: Learning, Memory, and Cognition, 26(3), 683-702 2000). The present
