Let $ $ be a commutative semigroup with identity $e$ and let $ $ be a compact subset in the pointwise convergence topology of the space $ '$ of all non-zero multiplicative functions on $ .$ Given a continuous function $F: \to \mathbb C$ and a complex regular Borel measure $ $ on $ $ such that $ ( ) \not = 0.$ It is shown that $$ ( ) \int_

Effect of neighborhood and plot size on experiments with multiple-harvest oleraceous crops
The objective of this work was to determine the efficiency of the Papadakis method on the quality evaluation of experiments with multiple-harvest oleraceous crops, and on the estimate of the covariate and the ideal plot size.

Covariance Hypotheses Which are Linear in Both the Covariance and the Inverse Covariance
both the covariance and the inverse covariance are products of models each of which consists of either (i) independent identically distributed random vectors which have a covariance with a real, complex or quaternion structure or (ii) independent identically distributed random vectors with a parametrization of the covariance which is given by means of ...

Stage‐Dependent Inhibitory Connectivity in Striatal‐Motor Circuit in Huntington's Disease
ABSTRACT Background Elucidating dysfunctional connectivity patterns among key brain regions in Huntington's disease (HD) underlying progression may have implications for developing treatment and therapeutic evaluation. Objective Explore the relationship between abnormal spontaneous resting‐state activity and atrophy in HD‐specific brain regions and ...

According to some generalized correspondence principle the classical limit of a non-Hermitian quantum theory describing quantum degrees of freedom is expected to be the well known classical mechanics of classical degrees of freedom in the complex phase space, i.e., some phase space spanned by complex-valued space and momentum coordinates.

BackgroundTreatment by covariate interactions can be explored in reviews using interaction analyses (e.g., subgroup analysis). Such analyses can provide information on how the covariate modifies the treatment effect and is an important methodological ...

COVARIANT QUANTIZATION OF THE SUPERSTRING [PDF]
After reviewing the Green-Schwarz superstring using the approach of Siegel, the superstring is covariantly quantized by constructing a BRST operator from the fermionic constraints and a bosonic pure spinor ghost variable. Physical massless vertex operators are constructed and, for the first time, N-point tree amplitudes are computed in a manifestly ...
