For determinate measures ß having moments of every order we define and study an index of determinacy which checks the stability of determinacy under multiplication by even powers of \t — z\ for z a complex number. Using this index of determinacy, we solve the problem of determining for which z£C the sequence {p\T\z))n ( m 6 N ) belongs to I2 , where (p„)„ is the sequence of orthonormal polynomi...

We report the generation of stacked optical precursors from a laser beam whose amplitude or phase is modulated by sequenced on-off step waveforms. Making use of the constructive interference between the precursors produced from different steps, as well as the main field, we generate optical transient pulses having peak powers of eight times the input power with electromagnetically induced trans...

An ample study of the comparative powers of a number of omnibus multivariate normality tests is main object in this paper. Since testing for multivariate normality tests is considerably more challenging process than for testing of univariate one and therefore, study of testing for multivariate normality tests has its increasing demand. Through this paper, we have explored several techniques for...

For any $k in mathbb{N}$, the $k$-subdivision of graph $G$ is a simple graph $G^{frac{1}{k}}$, which is constructed by replacing each edge of $G$ with a path of length $k$. In [Moharram N. Iradmusa, On colorings of graph fractional powers, Discrete Math., (310) 2010, No. 10-11, 1551-1556] the $m$th power of the $n$-subdivision of $G$ has been introduced as a fractional power of $G$, denoted by ...

The Center for Law and the Public's Health at Georgetown and Johns Hopkins Universities drafted the Model State Emergency Health Powers Act (MSEHPA or Model Act) at the request of the Centers for Disease Control and Prevention. The Model Act provides state actors with the powers they need to detect and contain bioterrorism or a naturally occurring disease outbreak. Legislative bills based on th...

BACKGROUND : We investigated whether independent prognostic factors for overall survival (OS) in non-small cell lung cancer such as ethnicity, smoking history, socioeconomic, and marital statuses are also applicable to extensive stage small cell lung cancer (ED-SCLC). METHODS : SCLC patients diagnosed from 1991 to 2005 from 3 Southern California counties were identified. Prognostic factors fo...

abstract west asia is a critical geopolitical region of eurasia. this region is a geographical center of crisis in all aspects. it is also an artificial term invented by the united states instead of the greater middle east. this geographical concept coves two regions stretching from the persian gulf to the caspian/ central asia. this region is recognized as the arab middle east, too. in the per...

abstractacquiring vocabulary, as a significant and challenging part of language learning process, has always been consistent with reading. in this study, the researchers examined the effect of enhanced extensive reading on efl learners’ incidental acquisition of english vocabulary, with specific focus on phrasal verbs. twenty five homogenized participants were selected and divided into two grou...
