The Anamas Block is located at the apex of Isparta Angle which one most important tectonic structures Anatolia. Angle, has a complex structure, was formed as result compressional and extensional events that initiated from Late Cretaceous continuing to present. GPS kinematic data indicate currently rotates clockwise due impact normal faults (Beyşehir Gölü Sarıidris) with minor right lateral stri...

We consider twisted tachyons on C/ZN orbifolds of bosonic closed string theory. It has been conjectured that these tachyonic instabilities correspond to decays of the orbifolds into flat space or into orbifolds with smaller deficit angles. We examine this conjecture using closed string field theory, with the string field truncated to low-level tachyons. We compute the tachyon potentials for C/Z...

We performed an angle-resolved photoemission spectroscopy study of BaFe2As2, which is the parent compound of the so-called 122 phase of the iron-pnictide high-temperature superconductors. We reveal the existence of a Dirac cone in the electronic structure of this material below the spin-density-wave temperature, which is responsible for small spots of high photoemission intensity at the Fermi l...

I watched how she swabbed his chest with antiseptic, injected lidocaine, which is a local anesthetic, and then, in full sterile garb, punctured his chest near his clavicle with a fat three-inch needle on a syringe. The patient hadn't even flinched. She told me how to avoid hitting the lung. ("Go in at a steep angle" she'd said. Stay right under the clavicle"), and how to find the subclavian vei...

A basic task of rescue robot systems is mapping of the environment. Localizing injured persons, guiding rescue workers and excavation equipment requires a precise 3D map of the environment. This paper presents a new 3D laser range finder and novel scan matching method for the robot Kurt3D [9]. Compared to previous machinery [12], the apex angle is enlarged to 360◦. The matching is based on sema...

Propagation of flexural localized vibration modes along edges of anisotropic wedges is considered in the framework of the geometrical-acoustics approach. Its application allows for straightforward evaluation of the wedge-mode velocities in the general case of arbitrary elastic anisotropy. The velocities depend on the wedge apex angle and on the mode number in the same way as in the isotropic ca...

A growing or shrinking disc will adopt a conical shape, its intrinsic geometry characterized by a surplus angle phi(e) at the apex. If growth is slow, the cone will find its equilibrium. Whereas this is trivial if phi(e)0. We construct these states in the regime where bending dominates and determine their energi...

We describe methods to measure the following properties of grey level corners: subtended angle, orientation, contrast, bluntness (or rounding of the apex), and boundary curvature (for cusps). Unlike most of the published methods for extracting these properties these methods are relatively simple, efficient and robust. They rely on the corner being pre-detected by a standard operator, thus makin...

A new species of Phallangothelphusa Pretzmann, 1965, is described from Cesar Department, Colombia, increasing the number of species in the genus to four: P. dispar (Zimmer, 1912), P. magdalenensis Campos, 1998, P. juansei Campos, 2010, and P. martensis new species. The new species is distinguished from its congeners primarily by the morphology of the first male gonopod, specifically the greater...
