The interplay between topological defects (branes) and black holes has been a subject of recent study, motivated in part by interest in brane-world scenarios. In this paper we analyze in detail the description of a black hole bound to a domain wall (a two-brane in four dimensions), for which an exact description in the limit of zero wall thickness has been given recently. We show how to smooth ...

The induced 4d gravity on a brane world is analyzed. The case of a thick brane is considered and the unexpected appearance of a new threshold scale, much larger than the thickness scale is found. In cases of phenomenological interest, this new length scale turns out to be in the submillimeter range. The effect of R corrections, both in the bulk and on the brane, is also studied. It is shown tha...

Thick disks are faint and extended stellar components found around several disk galaxies including our Milky Way. The Milky Way thick disk, the only one studied in detail, contains mostly old disk stars (≈ 10 Gyr), so that thick disks are likely to trace the early stages of disk evolution. Previous detections of thick disk stellar light in external galaxies have been originally made for early-t...

the upper cretaceous thick bedded succession in badamouyeh mountain in honooj area shows the late cenomanian-santonian stages. also, these deposits are well exposed in the south-west of bibihayat and south of cheshmah gaz village. in the studied section, lower and upper honooj green marls (informal) with intercalation of exogyroferous shaly limestone are overlain by thick bedded limestones and ...

Three dimensional SU (2) lattice gauge theory is studied after eliminating thin monopoles and the smallest thick monopoles. Kinematically this constraint allows the formation of thick vortex loops which produce Z(2) fluctuations at longer length scales. The thick vortex loops are identified in a three dimensional simulation. A condensate of thick vortices persists even after the thin vortices h...

BACKGROUND Patients with T4 N0 M0 melanoma are considered at high risk for having occult metastases, and adjuvant therapy is usually recommended. HYPOTHESIS Long-term survival in patients with thick melanoma is not universally poor. DESIGN A retrospective study. SETTING University teaching hospital. PATIENTS We evaluated clinical node-negative thick (> or = l4.0 mm) melanoma in 151 pati...

In the present paper I argue that the formalism of Newtonian mechanics stems directly from the general principle to be called the principle of microlevel reducibility which physical systems obey in the realm of classical physics. This principle assumes, first, that all the properties of physical systems must be determined by their states at the current moment of time, in a slogan form it is “on...

Due to its increased presence in the press and on television, the diagnosis of lipedema is on the way to becoming a trendy diagnosis for those with thick legs. Despite this, one must recognize that lipedema is a very rare disease. It is characterized by disproportional obesity of the extremities, especially in the region of the hip and the legs, hematoma development after minimal trauma, and in...

Significant progress has been made in the construction and theoretical understanding of molecular motors because of their potential use. Here, we have demonstrated fabrication of a simple but powerful 1 nm thick graphene engine. The engine comprises a high elastic membrane-piston made of graphene and weakly chemisorbed ClF3 molecules as the high power volume changeable actuator, while a 532 nm ...

Let E be a set of n objects in fixed dimension d. We assume that each element ofE has diameter smaller than D and has volume larger than V . We give a new divide and conquer algorithm that reports all the intersecting pairs in O(n logn + Dd V (n + k)) time and using O(n) space, where k is the number of intersecting pairs. It makes use of simple data structures and primitive operations, which ex...
