In this preliminary biometric study of the calcareous nannofossil species Chiasmolithus expansus, Chiasmolithus oamaruensis, and Chiasmolithus altus from the upper middle Eocene to lower Oligocene of Sites 647 and 748, we document a complete gradation of forms among all three species. Chiasmolithus oamaruensis has significantly higher morphologic variance than the other species. The Chiasmolith...

The mechanism by which cell and cell membrane shapes are created has long been a subject of great interest. Among the phosphoinositide-binding proteins, a group of proteins that can change the shape of membranes, in addition to the phosphoinositide-binding ability, has been found. These proteins, which contain membrane-deforming domains such as the BAR, EFC/F-BAR, and the IMD/I-BAR domains, led...

We examined how contours defined by different attributes are integrated into a shape using the visual search paradigm and found that the search for the bar orientation is particularly difficult when each bar is composed of motion-defined and luminance- or color-defined contours. This does not support the view that the shape integration process is based on the unified contour representation enti...

A headed reinforcing bar is a new type of reinforcement with a T-shaped anchor connected to the end of a reinforcing bar. Conceptually, the bar is usually a tension member or compression one depending on structural engineering applications. The T-shaped anchor, referred to as head in the rest of this report is a relatively stiff steel "plate" in terms of its structural behavior. When embedded i...

The crescent-shaped BAR (Bin/Amphiphysin/Rvs-homology) domain dimer is a versatile protein module that senses and generates positive membrane curvature. The BAR domain dimer of human endophilin-A1, solved at 3.1 A, has a unique structure consisting of a pair of helix-loop appendages sprouting out from the crescent. The appendage's short helices form a hydrophobic ridge, which runs across the co...

We present preliminary results of our modelling of the J,K,L and M band emission detected by the DIRBE instrument on the COBE satellite. Our model includes the contribution of Zodiacal light and a three-dimensional model for the distribution of dust based upon DIRBE observations of dust emission at 240 microns. Our approach enables us to construct dust removed maps of our Galaxy that we will us...

Little is known of how visual coding of the shape of an object affects grasping movements. We addressed this issue by investigating the influence of shape perturbations on grasping. Twenty-six participants grasped a disc or a bar that were chosen such that they could in principle be grasped with identical movements (i.e., relevant sizes were identical such that the final grips consisted of iden...

ABSTRACT We analyse the positions of RR Lyrae stars in central region Milky Way. In addition to overall bar shape detected previously, we find evidence for a peanut shaped structure, form overdensities near ℓ = −2 and 1° at b ∼ −3.5°. The corresponding physical distance between two peaks is $\sim 0.7\,$ kpc, significantly shorter than that found from near-IR images (3.3 kpc) red-clump stars. Qu...

Using data samples with a total integrated luminosity of approximately 18 fb$^{-1}$ collected by the BESIII detector operating at BEPCII, process $e^+e^-\rightarrow\Lambda\bar{\Lambda} \eta$ is studied center-of-mass energies between 3.5106 and 4.6988 GeV. The Born cross section for $e^+e^-\rightarrow\Lambda\bar{\Lambda}\eta$ measured. No significant structure observed in line shape. An enhance...
