Initialising and managing security parameters for personal mobile devices within a Personal Area Network (PAN) presents a variety of security problems. In this paper we consider one possible paradigm for mobile device security management, namely the use of a ‘personal CA’ to provide certificates within a PAN. The security requirements for such a personal CA are analysed, and a novel protocol fo...

The study was carried out with 38 collected garlic (Allium sativum L.) cultivars from 3 important garlic production area in Iran (Zanjan, Hamadan and Mazandaran). The cloves were planted in 30 × 30 cm pots in control conditions (average temperature: 20 °C and 60 % RH). Randomized complete block design with 3 replications was conducted. The bulbing characteristics such as bulb weight, bulb circu...

With the rapid advance of mobile computing, high speed Wireless Local Area Networks (LAN) attracts a lot of research interests in recent years. A new international stander IEEE 802. 11 on wireless LAN has been established. Its physical transmission is realized by either spread spectrum communication or non-directive infrared. The medium access control of IEEE 802. 11 is using carrier sense mult...

The Ising-like phase transition is considered in probabilistic cellular automata (CA). The nonequilibrium CA with Toom rule are compared to standard equilibrium lattice systems to verify influence of synchronous vs asynchronous updating. It was observed by Marcq et al. [Phys.Rev.E 55(1997) 2606] that the mode of updating separates systems of coupled map lattices into two distinct universality c...

background: despite echinococcus granulosus , there are merely two old reports of e. multilocularis in-fection among iranian canids of moghan plain, the only area known endemic for the species. we detected specific dna markers in fecal samples by pcr (copro-pcr) for differential diagnosis of echinococcus species in living canids. methods: totally 144 fecal samples from domestic dogs, red foxes ...

We describe the isolation and characterization of several rat brain cDNAs that are homologous to the alpha 1 subunit of heart and skeletal muscle dihydropyridine-sensitive Ca channels. Northern blot analysis of 32 cDNAs shows that they can be grouped into four distinct classes (A, B, C, and D), each corresponding to a distinct hybridization pattern of brain mRNAs. Southern blot and DNA sequenci...

Adequate responses to noxious stimuli causing tissue damages are essential for organismal survival. Class IV neurons in Drosophila larvae are polymodal nociceptors responsible for thermal, mechanical, and light sensation. Importantly, activation of Class IV provoked distinct avoidance behaviors, depending on the inputs. We found that noxious thermal stimuli, but not blue light stimulation, caus...
