We present an annotated checklist for a total 241 reptiles and 22 amphibians including 5 frogs, 9 toads, 7 newts and salamanders, 1 crocodile, 1 worm lizard, 148 lizards, 79 snakes and 12 turtles and tortoises, includes the most scientific literature up to August 2014 and also based on several field surveys conducted in different Provinces of Iran from 2009 to 2014. We present an up-to-dated checklist of reptiles and amphibians in Iran. We provide a comprehensive listing of taxonomy, names, distribution and conservation status of all amphibians and reptiles of Iran. This checklist includes all recognized named taxa, English names for classes, orders, families, species, subspecies along with Persian names for species, including indication of native and introduced species. For the first time we report two non-native introduced reptiles from natural habitats of Iran. Of the total 22 species of amphibians in Iran, 6(27.2%) are endemic and of the total 241 species of reptiles, 55(22.8%) are endemic. Of the 22 amphibians species in Iran, 3(13%) are Critically Endangered, 2(9%) are Vulnerable and of the 241 reptile species 3(1.2%) are Critically Endangered, 4(1.6%) are Endangered and 10(4.1%) are Vulnerable. Accordingly, this paper combines significant aspects of taxonomy, common names, conservation status and distribution of the Iranian herpetofauna.

In view of the large scientific and technical interest in the microelectromechanical system(MEMS)accelerometer sensor and the limitations of capacitive,resistive piezo,and piezoelectric methods,we focus on the measurement of the seismic mass displacement using a novel design of the all-optical sensor(AOS).The proposed AOS consists of two waveguides and a ring resonator in a two-dimensional rod-based photonic crystal(PhC)microstructure,and a holder which connects the central rod of a nanocavity to a proof *** photonic band structure of the AOS is calculated with the plane-wave expansion approach for TE and TM polarization modes,and the light wave propagation inside the sensor is analyzed by solving MaxwelFs equations using the finite-difference time-domain *** results of our simulations demonstrate that the fundamental PhC has a free spectral range of about 730 nm covering the optical communication *** also show that the AOS has the resonant peak of 0.8 at 1.644μm,quality factor of 3288,full width at half maximum of 0.5nm,and figure of merit of ***,for the maximum 200nm nanocavity displacements in the x-or y-direction,the resonant wavelengths shift to 1.618μm and 1.547μm,*** also calculate all characteristics of the nanocavity displacement in positive and negative directions of the jc-axis and *** small area of 104.35μm^(2)and short propagation time of the AOS make it an interesting sensor for various applications,especially in the vehicle navigation systems and aviation safety tools.

Let G = (V,E) be a graph, where V(G) is a non-empty set of vertices and E(G) is a set of edges, e = uv∈E(G), d(u) is degree of vertex u. Then the first Zagreb polynomial and the first Zagreb index Zg1(G,x) and Zg1(G) of the graph G are defined as Σuv∈E(G)x(du+dv) and Σe=uv∈E(G)(du+dv) respectively. Recently Ghorbani and hosseinzadeh introduced the first Eccentric Zagreb index as Zg1*=Σuv∈E(G)(ecc(v)+ecc(u)), that ecc(u) is the largest distance between u and any other vertex v of G. In this paper, we compute this new index (the first Eccentric Zagreb index or third Zagreb index) of an infinite family of linear Polycene parallelogram of benzenoid.
