Abstract In this study, we conduct an analysis of traversable wormhole solutions within the framework linear gravity, ensuring that all energy conditions hold for entire spacetime. The presented in paper are derived through a comprehensive analytical examination parameter space associated with model. This involves considering exponents governing redshi...

The electromagnetic elastic form factors of pseudoscalar and vector mesons are analyzed for space-like momentum transfers in terms of relativistic quark models based on the Hamiltonian light-front formalism elaborated in different reference frames (q+ = 0 and q+ 6= 0). As far as the one-body approximation for the electromagnetic current operator is concerned, it is shown that the predictions of...

A mathematical model based on d-q axis theory and dynamic performance characteristic of brushless resolvers is discussed in this paper. The impact of rotor eccentricity on the accuracy of position in precise applications is investigated. In particular, the model takes the stator currents of brushless resolver into account. The proposed model is used to compute the dynamic and steady state e...

the danger of qualitative research methodologies falling into the fatal trap of relativism and null (non-existent) reality in an honest and worthy pursuit to emancipate human knowledge and understanding from the dominant account offered by quantitative methodologies is a serious one. it should be taken as even more serious for research communities who have just begun to practice breaking away f...

Fast radio bursts (FRBs) are mysterious astronomical transients with extremely short intrinsic duration. Until now, the physical origins of them still remain elusive especially for non-repeating FRBs. Strongly inspired by recent progress on possible evidence Earth-mass primordial black holes, we revisit model holes mergers as sources Under null hypothesis that observed FRBs originated from anal...

We consider the problem of testing a particular type of composite null hypothesis under a nonparametric multivariate regression model. For a given quadratic functional Q, the null hypothesis states that the regression function f satisfies the constraint Q[f ] = 0, while the alternative corresponds to the functions for which Q[f ] is bounded away from zero. On the one hand, we provide minimax ra...

We prove the following theorem: For a partially ordered set Q such that every countable subset has a strict upper bound, there is a forcing notion satisfying ccc such that, in the forcing model, there is a basis of the null ideal of the real line which is order-isomorphic to Q with respect to set-inclusion. This is a variation of Hechler’s classical result in the theory of forcing, and the stat...

3Cf. Fubini, loc. cit., p. 54. 4 If the determinant gx, I for x, ,u = 1, ,(q < n) is zero, real quantities e are defined by the equations gxtx = 0. The vector with the components 0, {a = o (or = q + 1, ... . n) is a real null vector, which is impossible, if the fundamental form is definite. In a similar manner it can be shown that the determinant I gjt for a-,= 1, ..., p cannot be zero for a de...

In word alignment certain source words are only needed for fluency reasons and do not have a translation on the target side. Most word alignment models assume a target NULL word from which they generate these untranslatable source words. Hypothesising a target NULL word is not without problems, however. For example, because this NULL word has a position, it interferes with the distribution over...
