Spin labels have now enjoyed a history of close to twenty-five years in demonstrating the applicability of paramagnetic nitroxides to biochemical problems of structure and function in enzymes, membranes, cells and animals. These have been employed traditionally as reporter groups; that is, the nitroxide spin label serves as a physical probe which reports aspects of its structure and environment...

OBJECTIVE Amnestic mild cognitive impairment (aMCI) involves episodic memory. The person who presents aMCI has a high risk of developing Alzheimer's disease (AD). However, prediction of deterioration to dementia in cases of aMCI can be confounded with depression due to lack of specificity on selective memory tests. Finding a test sensitive to aMCI but not to depression would be potentially most...

The hippocampus plays a crucial role within the neural systems for long-term memory, but little if any role in the short-term retention of some types of stimuli. Nonetheless, the hippocampus may be specialized for allocentric topographical processing, which impacts on short-term memory or even perception. To investigate this we developed performance-matched tests of perception (match-to-sample)...

There is a need for appropriate classification to describe gross motor function status in a child with cerebral palsy (CP). It was hypothesised that: greater the number of limbs involved, higher would be the Gross Motor Function Classification System (GMFCS) level; and, there would be spectrum of GMFCS level for each of the topographical types of the cerebral palsy. A cross-sectional study of 1...

The complex topography of subtropical montane forests favors the coexistence diverse plant species, making these species-rich a high priority for biodiversity monitoring, prediction, and conservation. Mapping tree species distribution accurately in areas is an essential basis research often challenging due to their structure. Remote sensing has widely been used mapping but relatively little att...

A large-scale virtual reality town was used to test the topographical and episodic memory of patients with unilateral temporal lobe damage. Seventeen right and 13 left temporal lobectomy patients were compared with 16 healthy matched control subjects. After they had explored the town, subjects' topographical memory was tested by requiring them to navigate to specific locations in the town. The ...

Abbreviations: RTL = Right temporal lobectomy, LTL = Left temporal lobectomy ABSTRACT A large-scale virtual reality town was used to test the topographical and episodic memory of patients with unilateral temporal lobe damage. Seventeen right and 13 left temporal lobectomy patients were compared with 16 healthy matched control subjects. After they had explored the town, subjects' topographical m...

Making sense of concept maps is an ongoing challenge for the concept mapping community. This paper introduces a multilevel analysis strategy by combining quantitative and qualitative methods to triangulate changes in students’ concept maps. Quantitative analysis includes overall, selected, and weighted propositional analysis using a knowledge integration rubric (Linn, 2000) as well as network a...

Neural circuit mapping is generating datasets of tens of thousands of labeled neurons. New computational tools are needed to search and organize these data. We present NBLAST, a sensitive and rapid algorithm, for measuring pairwise neuronal similarity. NBLAST considers both position and local geometry, decomposing neurons into short segments; matched segments are scored using a probabilistic sc...

Since the shorelines are important geographical boundaries, monitoring shoreline change plays an role in integrated coastal management. With evolution of remote sensing technology, many studies have used optical images to measure and extract shoreline. However, some factors limit use imaging on mapping. Considering that airborne LiDAR data can provide more accurate topographical information, th...
