distinguishing the susceptible areas to landslide using different landslide susceptibility mapping (lsm) models is one of the primitive and basic works to reduce probable damages and reduce risk. the main purpose of this research is the efficiency evaluation of four methods including information value (winf), valuing area accumulation (wa), analytical hierarchy process (ahp), kopta-joshi propos...

We demonstrate for the first time an optically pumped gas laser based on population inversion using a hollow core photonic crystal fiber (HC-PCF). The HC-PCF filled with 12C2H2 gas is pumped with ~5 ns pulses at 1.52 μm and lases at 3.12 μm and 3.16 μm in the mid-infrared spectral region. The maximum measured laser pulse energy of ~6 nJ was obtained at a gas pressure of 7 torr with a fiber with...

In 1992 Carlsen et al. reported a significant global decline in sperm density between 1938 and 1990 [Evidence for Decreasing Quality of Semen during Last 50 Years. Br Med J 305:609-613 (1992)]. We subsequently published a reanalysis of the studies included by Carlsen et al. [Swan et al. Have Sperm Densities Declined? A Reanalysis of Global Trend Data. Environ Health Perspect 105:1228-1232 (1997...

The present study examined F1 and F2 onset, as well as locus equations in Greek fricative – vowel sequences as distinctive cues for the fricative place of articulation. The effects of voicing, speaker’s gender and post-fricative vowel on both formants’ onset values and locus equations were also investigated. The results showed that F2 onset values distinguished fricatives in terms of place of a...

We study the relationship between incidence for lung cancer in males in the Tuscan Region and material deprivation defined at census block level. We developed a bi-variate hierarchical Bayesian model to assess completeness of registration of incidence data and we proposed a series of random effect hierarchical Bayesian models to estimate the degree of association with material deprivation. Mode...

Biometric latent growth curve models were applied to data from the LTS in order to replicate and extend Wilson's (Child Dev 54:298-316, 1983) findings. Assessments of cognitive development were available from 8 measurement occasions covering the period 4-15 years for 1032 individuals. Latent growth curve models were fit to percent correct for 7 subscales: information, similarities, arithmetic, ...

Accurate terrain representation with appropriate preservation of important terrain characteristics, especially slope steepness is becoming more crucial and fundamental as the geographical models are getting more complex and commonly used. Based on our earlier success in Overdetermined Laplacian Partial Differential Equation (ODETLAP), which allows for compact yet accurate compression of the Dig...
