Humans can recover the structure of a three-dimensional object from motion cues alone. Recovery of structure-from-motion (SFM) from the projected 2D motion field of a rotating object has been studied almost exclusively in the condition where the axis of rotation lies in the frontoparallel plane. Here we assess the ability of humans to recover SFM in the general case, where the axis of rotation ...

The inner tube layer of Pomatoceros americanus has a complex oriented ultrastructure, which cannot be explained by the standard granular secretion model, predicting a largely unoriented structure of the tube. In the lamello-fibrillar structure of the inner tube layer, the crystallization axis of crystals has a uniform orientation, which is not continuous through successive growth increments. Th...

The basic AB problem is to determine how an unshielded tube of magnetic flux Φ affects arbitrarily long-wavelength charged particles impinging on it. For spin-1 at almost all Φ the particles do not penetrate the tube, so the interaction essentially is periodic in Φ (AB effect). Below-threshold bound states move freely only along the tube axis, and consequent induced vacuum currents supplement r...

This paper presents a numerical investigation on heat transfer enhancement by using computational fluid dynamics software. The is implemented inserting twisted tape into exchanger tube. tapes with twist ratios of 4, 6 and 8 were modified alternate axis. pitch the having rotation direction such as clockwise counterclockwise are connected 90º connection angle.

The halos of elliptical galaxies are faint and difficult to explore, but they contain vital clues to both structure and formation. We present the results of an imaging and spectroscopic survey for planetary nebulae (PNe) in the nearby elliptical NGC 5128. We extend the work of Hui et al. (1995) well into the halo of the galaxy—out to distances of 100 and 50 kpc along the major and minor axes. W...

background:  matricaria chamomilla is an ancient herbal drug widely consumed to sexual system improvement. the aim of this research was to study the effect of matricaria chamomilla hydroalcholic extract on the pituitary-testis axis and testes tissues of male rats. methods:  mature male rats were randomly assigned to two groups: the matricaria group (100 mg/kg of matricaria chamomilla extract vi...

A flexible antenna of compact size with a dual band elliptical-shape implantable is designed for biomedical purposes. The suggested has an elliptical shape to be more comfortable being implanted in human tissue. printed on RO3010 substrate 2 mm as thickness and 10.2 dielectric constant. It consists active planar C-shaped element parasitic inverted element. proposed major axis radius 12 minor 8 ...

It is shown that the number of members, NA, and the linear radius of the Abell clusters at z < 0.18 increase with redshift. The increase is caused by observational selection: the number of rich and large clusters is small in the nearby small volume of space, while poor and small clusters are not detected at high distances. Besides, the numbers of clusters with different ellipticities are about ...

Fibrochondrocytes within meniscal tissue have been shown to alter their biochemical activity in response to changes in their mechanical environment. Meniscal tissue is known to contain both spherical (chondrocytic-like) and elliptical (fibroblastic-like) cells. We hypothesize that a cell's mechanical environment is governed by local material properties of the tissue around the cell, the cell mo...

We demonstrate all-optical linear polarization control of exciton-polariton condensates in anisotropic elliptical optical traps. The cavity inherent TE-TM splitting lifts the ground state spin degeneracy with emerging fine structure modes polarized parallel and perpendicular to trap major axis condensate populating latter. Our findings show a new type exciting perspectives both spinoptronics st...
