Technical limitations in image capturing usually impose defective, such as contrast degradation. There are different approaches to improve the contrast of an image. Among the exiting approaches, un-sharp masking is a popular method due to its simplicity in implementation and computation. There is an important parameter in un-sharp masking, named gain factor, which affects the quality of the enh...

A set is an unordered (unless otherwise specified) collection of elements of the same type, usually expressed using the following notation: {elem1, elem2, elem3, . . .} A tuple is an ordered collection of elements, not necessarily of the same type, expressed using the following notation: (elem1, elem2, elem3, . . .) Most of the times, we don’t give too much attention to the actual elements them...

The simplest interpretation of the global success of the Standard Model is that new physics decouples well above the electroweak scale. Supersymmetric extension of the Standard Model offers the possibility of light chargino and the right-handed stop (with masses below MZ), and still maintaining the successful predictions of the Standard Model. The value of Rb can then be enhanced up to ∼ 0.218 ...

We used quantitative genetics techniques to compare the entrepreneurial activity of 870 pairs of monozygotic (MZ) and 857 pairs of same-sex dizygotic (DZ) twins from the United Kingdom. We ran model-fitting analyses to estimate the genetic, shared environmental and nonshared environmental effects on the propensity of people to become entrepreneurs. We found relatively high heritabilities for en...

Abstract. For any odd squarefree integer r, we get complete description of the Gr = Gal(Q(μr)/Q) group cohomology of the universal ordinary distribution Ur in this paper. Moreover, if M is a fixed integer which divides l−1 for all prime factors l of r, we study the cohomology group H(Gr, Ur/MUr). In particular, we explain the mysterious construction of the elements κr′ for r |r in Rubin[10], wh...

A direct proof is given here which shows that instead of 6 complex numbers, the triangular mass matrix for each sector could just be expressed in terms of 5 by performing a specific weak basis transformation, leading therefore to a new textures for triangular mass matrices. Furthermore, starting with the set of 20 real parameters for both sectors, it can shown that 6 redundant parameters can be...

We conducted an AX-discrimination task to test for differences in perceived auditory similarity in monozygotic (MZ) and dizygotic (DZ) twin pairs and unrelated speakers. In addition, we performed acoustic analyses to find acoustic correlates that explain the differences in perceived similarity. Results indicate that unrelated speakers are significantly easier to distinguish than twins, but zygo...

In this paper, we establish a lower bound on the number of inducing simple n-gons in grid-like arrangements of lines. We also show that the complexity associated with counting the number of inducing n-gons in an arrangement of collinear segments is #P-complete.
