Statistical studies on Palynology contents of Late Cretaceous to Paleocene age Gurpi Formation in a surface section in Zagros Basin,SW Iran indicate changes in abundance, species diversity, ratio of Spiniferites to Cyclonephelium (S/C), palynological marine index(PMI) values and organic facies. These palynological variations clearly reflect fluctuations in relative sea-level and depositionalenv...

Frontal and temporal language areas involved in syntactic processing are connected by several dorsal and ventral tracts, but the functional roles of the different tracts are not well understood. To identify which white matter tract(s) are important for syntactic processing, we examined the relationship between white matter damage and syntactic deficits in patients with primary progressive aphas...

Axon-guidance by Slit-Roundabout (Robo) signaling at the midline initially guides growth cones to synaptic targets and positions longitudinal axon tracts in discrete bundles on either side of the midline. Following the formation of commissural tracts, Slit is found also in tracts of the commissures and longitudinal connectives, the purpose of which is not clear. The Slit protein is processed in...

A-tracts are functionally important DNA sequences which induce helix bending and have peculiar structural properties. While A-tract structure has been qualitatively well characterized, their mechanical properties remain controversial. A-tracts appear structurally rigid and resist nucleosome formation, but seem flexible in DNA looping. In this work, we investigate mechanical properties of symmet...

Homopolymeric stretches of deoxyadenosine nucleotides (A's) on one strand of double-stranded DNA, referred to as poly(dA:dT) tracts or A-tracts, are overabundant in eukaryotic genomes. They have unusual structural, dynamic, and mechanical properties, and may resist sharp bending. Such unusual material properties, together with their overabundance in eukaryotes, raised the possibility that poly(...

We present a coloring method that conveys spatial relations between DTI fiber tracts effectively; similar tracts are assigned to similar colors and different tracts are assigned to different colors in a smooth and continuous manner. To this end, we combine a standard spectral approach with a mass-spring heuristic to embed fiber tracts into a perceptually uniform color space, L*a*b*. We also int...

MOTIVATION Detecting IBD tracts is an important problem in genetics. Most of the existing methods focus on detecting pairwise IBD tracts, which have relatively low power to detect short IBD tracts. Methods to detect IBD tracts among multiple individuals simultaneously, or group-wise IBD tracts, have better performance for short IBD tracts detection. Group-wise IBD tracts can be applied to a wid...

BACKGROUND There is increasing interest in the study of place effects on health, facilitated in part by geographic information systems. Incomplete or missing address information reduces geocoding success. Several geographic imputation methods have been suggested to overcome this limitation. Accuracy evaluation of these methods can be focused at the level of individuals and at higher group-level...

The tractability and integrity of fiber tracts within an edema, and the functional roles of long-range fiber tracts during language processing are discussed controversially. We studied the dorsal and ventral language fiber tracts of patients initially presenting with a peritumoral edema in both their pre-and postoperative states. Here, we report preliminary results of three patients. Diffusion ...
