the presence of supernumerary teeth is not uncommon in the general population. they occur more frequently in patients with a family history of such teeth but it is rare to find multiple supernumeraries in individuals with no other associated disease or syndrome. there have been very few documented cases of bilateral maxillary and mandibular supernumeraries, distal to the third molars. supernume...

At about the 20-30 day of embryonic life "Somites" start to appear. In the middle of the fourth week the dorsal portion of each Somite differentiates into an epithelially­arranged mass of cells called der­momyotome (from which the skin and mus­cles originate).  The lateral part of the sermomyotome then proliferates to form dermatome (from ·which originates the derm and Hypoderm).  The medial ...

The construction of dolmens took place in Europe from the Neolithic to Early Bronze Age (fifth millennium BC–second BC) and had a rapid development along Atlantic façade, with an important focus Andalusia. Within this area, megalithic necropolises located banks Gor River (Granada, Andalusia, Spain) are studied. In paper, multivariate techniques applied characterize associated river landscape by...

in future high-speed self-routing photonic networks based on all-optical time division multiplexing (otdm) it is highly desirable to carry out packet switching, clock recovery and demultplexing in the optical domain in order to avoid the bottleneck due to the optoelectronics conversion. in this paper we propose a self-routing otdm node structure composed of an all-optical router and demultiplex...

we give a new proof of the well known wedderburn's little theorem (1905) that a finite‎ ‎division ring is commutative‎. ‎we apply the concept of frobenius kernel in frobenius representation theorem in finite group‎ ‎theory to build a proof‎.

In mobile communication, the most exploratory technology of fifth generation is massive multiple input output (MIMO). The minimum mean square error and zero forcing based linear detectors are used in multiuser detection for MIMO single-carrier frequency division access (SC-FDMA). When received signal detected regularization sequence joined equalization spectral null amplification, these schemes...
