We describe Very Large Array observations of the extreme carbon star IRC+10216 at 8.4, 14.9, and 22.5 GHz made over a two year period. We find possible variability correlated with the infrared phase and a cm-to sub-millimeter wavelength spectral index very close to 2. The variability, observed flux densities, and upper limit on the size are consistent with the emission arising from the stellar ...

The World Wide Web (WWW) poses a distinct capability to offer interventions tailored to the individual's characteristics. To fine tune the tailoring process, studies are needed to explore how Internet accessibility and usage are related to demographic, psychosocial, behavioral, and other health related characteristics. This study was based on a cross-sectional survey conducted on 2373 7th grade...

An improved formula is derived for accurately computing the near-zone magnetic field of a s mall c irc ular transmitting loop an tenna. Such a field can serve as a reference standard for calibrating fi eld-strength meters e mploying small receiving loop anten nas in the frequency range 30 Hz to 30 MHz. This formula inc ludes correction terms for fr equency (d ue to the finite time of propagatio...

In the case d = 1, the properties of the system D = D1 are the subject of the well-known 3x + 1 conjecture. For every one of 6667 systems Dd, 1 ≤ d ≤ 19999, we calculate its (complete, as we argue) list of primitive cycles. We unite in a single conceptual framework of primitive memberships, and we experimentally confirm three primitive cycles conjectures of Jeff Lagarias. An in-deep analysis of...

In recent years, smart environments have emerged as a key target area for ubiquitous and pervasive computing research. As technologists contemplate moving the focus of their research from proprietary laboratories into ‘real living spaces’, such as the domestic environment, it becomes important to gain an understanding of existing work and experiences in this area. As part of our work within the...

The aim of this study, through the estimation of a cost function, is to estimate the scale economies and scale and X-inefficiencies of commercial banks operating in Indonesia with a view to identifying hypothetical mergers that could deliver significant cost savings. Economies of scale are typically only found for the largest and smallest banks, with the industry’s estimated scale inefficiency ...

This report mainly discusses the adaptability of the IRC-based Bot detection method to be used in the P2P-based Bot detection. The first section introduces the IRC-based bot and the newly appeared P2P-based bot to see their difference. The second section shows the related work and the traditional method of BOTNET detection. The third section discusses the methodology used by the IRC based Botne...

The isotope effects appear as the deviation and unsymmetrization of the potential profile along the IRC in the mass-weighted Cartesian coordinate system, whereas in the ordinary nonmass-weighted Cartesian coordinate system they appear as the differences of the effective mass. The analysis of tunneling probability has shown that the difference in the effective mass which is greatest in the vicin...
