Evaluation of EREP techniques for geological mapping

The author has identified the following significant results. Skylab photographs may be successfully utilized for preparing a reconnaissance geological map in the areas where no maps or semi-detailed maps exist. Large coverage of area and regional perspective from Skylab photographs can help better coordination in regional mapping. It is possible to delineate major structural trends and other features like mega-lineaments, geofractures, and faults, which have evaded their detection by conventional methods. The photointerpretability is better in areas dominated by sedimentary rocks. Rock units of smaller extent and having poor geomorphic expressions are difficult to map. Demarcation of quaternary river alluvium can be made with better precision and ease with the Skylab photographs. Stereoscopic viewing greatly helps in interpretation of area structures. Skylab photographs are not good for preparing geological maps larger than 1:270,000 scale

Interpolation function of the genocchi type polynomials

The main purpose of this paper is to construct not only generating functions of the new approach Genocchi type numbers and polynomials but also interpolation function of these numbers and polynomials which are related to a, b, c arbitrary positive real parameters. We prove multiplication theorem of these polynomials. Furthermore, we give some identities and applications associated with these numbers, polynomials and their interpolation functions.Comment: 14 page

Quasideuterons in Light Nuclei

The role of pairing correlations for nucleon pairs with isospin $T=1$ and $T=0$ is investigated for nuclei in the mass region $12 \leq A \leq 42$. For that purpose the two-nucleon densities resulting from nuclear shell-model calculations in one and two major shells are analyzed. Significant effects on the resulting energies are observed due to the formation of $T=0$ pairs. The formation of quasi-deuterons is maximal for symmetric nuclei with $N=Z$. The formation of $T=0$ pairs is less sensitive to the density of single-particle states close to the Fermi energy than the $T=1$ pairing and is relevant also for excitations across shell-closures. This robustness also explains why $T=0$ pairing does not lead to such a clear evidence in comparing energies of neighbored nuclei as the "odd-even mass staggering" due to the formation of $T=1$ pairing.Comment: 8 pages, 5 figur

Excitation of the Lowest Autoionizing Levels in Lithiumlike Ions by Electron Impact

We present theoretical, differential, and total cross sections for electron impact excitation of the lowest autoionizing levels of various lithiumlike ions (viz., Be+, B2+, C3+, O5+, and Ne7+). For these ions, the autoionizing level of interest results from excitation of an inner-shell electron. A distorted-wave Born approximation (with exchange) is used for the calculation. The present results are compared with previous theoretical calculations and it is concluded that the Coulomb-Born approach is unreliable, particularly near threshold

Uniqueness of nontrivially complete monotonicity for a class of functions involving polygamma functions

For $m,n\in\mathbb{N}$, let $f_{m,n}(x)=\bigr[\psi^{(m)}(x)\bigl]^2+\psi^{(n)}(x)$ on $(0,\infty)$. In the present paper, we prove using two methods that, among all $f_{m,n}(x)$ for $m,n\in\mathbb{N}$, only $f_{1,2}(x)$ is nontrivially completely monotonic on $(0,\infty)$. Accurately, the functions $f_{1,2}(x)$ and $f_{m,2n-1}(x)$ are completely monotonic on $(0,\infty)$, but the functions $f_{m,2n}(x)$ for $(m,n)\ne(1,1)$ are not monotonic and does not keep the same sign on $(0,\infty)$.Comment: 9 page

Energy Dependence of Short and Long-Range Multiplicity Correlations in Au+Au Collisions from STAR

A general overview of the measurement of long-range multiplicity correlations measured by the STAR experiment in Au+Au collisions at RHIC is presented. The presence of long-range correlations can provide insight into the early stages, and the type of matter produced in, these collisions. These measurements have been made in Au+Au collisions at $\sqrt{s_{NN}}$ = 200 and 62.4 GeV. These results indicate a relatively large long-range correlation is produced in Au+Au collisions compared to a {\it pp} baseline at $\sqrt{s_{NN}}$ = 200 GeV. A weaker long-range correlation is seen as a function of incident energy. Further, comparison of the onset of the long-range correlation to the calculated percolation density parameter at $\sqrt{s_{NN}}$ = 200 GeV is presented.Comment: 8 pages, 6 figures, Conference Proceedings for the XI International Workshop on Correlation and Fluctuation in Multiparticle Production, Hangzhou, China, November 21-25, 200

Performance Impacts of E-Government: An International Perspective

Though policy makers and governments are interested in understanding the impacts of e- Government on national performance, there are relatively few empirical studies that analyze this aspect. Using secondary data from 99 countries and the IT impact literature as the guiding theoretical perspective, we first examine the impact of e-Government on first order government efficiency parameters (resource allocation and internal operations efficiency) and subsequently the impact of these first order outcomes on the two second order dimensions of national performance (social welfare and business competitiveness). Our initial analysis reveals a significant relationship between e-government development and resource allocation efficiency and also between e-Government development and internal operations efficiency. For the second order model, we find that the relationship between internal operations efficiency and social welfare competitiveness is not significant. We conducted a post-hoc analysis which revealed that the relationship between internal operational efficiency and social welfare competitiveness is fully mediated through national business competitiveness. Hence, business competitiveness emerges as an important aspect for realizing the social welfare benefits of e-Government. Through this research, we make some important contributions and implications for researchers, practitioners and policy makers
