Introduction: Xerostomia is the most common complication due to radiation–induced damage to salivary glands in head and neck cancer radiotherapy and it reduces quality of life. Parotid glands are main glands which they are account for secretion of stimulated saliva. Studies have demonstrated that mean tolerance parotid’s radiation dose under 26-30 Gy result in an increase in t...

The importance of the prime factorization problem is very well known (e.g., many security protocols are based on the impossibility of a fast factorization of integers on traditional computers). It is necessary from a number k to establish two primes a and b giving k = a · b. Usually, k is written in a positional numeral system. However, there exists a variety of numeral systems that can be used...

Hardware variance can significantly degrade the positional accuracy of RSS-based WiFi localization systems. Although manual adjustment can reduce positional error, this solution is not scalable as the number of new WiFi devices increases. We propose an unsupervised learning method to automatically solve the hardware variance problem in WiFi localization. This method was designed and implemented...

background: meniere’s disease (md) is a chronic illness defined as an idiopathic syndrome of endolymphatic hydrops. benign paroxysmal positional vertigo (bppv) is a balance disorder and can be the sequel of diverse inner ear impairments. objectives: the purpose of this study was to investigate the prevalence of bppv in md patients. materials and methods: all patients with definite or probable m...

This paper is concerned with design, implementation and verification of persistent purely functional data structures which are motivated by the representation of natural numbers using positional number systems. A new implementation of random-access list based on redundant segmented binary numbers is described. It uses 4 digits and an invariant which guarantees constant worst-case bounds for con...

BACKGROUND Cell position rather than cell lineage governs most aspects of development in plants. However, the nature and the origin of positional information remains elusive. Animal epidermal patterning relies in many cases on positional information provided by cell-cell communication. The epidermal layer of the Arabidopsis root is made of alternating files of two cell types and thus presents a...
