Averaged null energy condition from causality [PDF]
Journal of High Energy Physics, 2016 Unitary, Lorentz-invariant quantum field theories in flat spacetime obey mi-crocausality: commutators vanish at spacelike separation. For interacting theories in more than two dimensions, we show that this implies that the averaged null energy, ∫ duTuu ...

Anisotropic Null String Cosmologies [PDF]
, 1998 We study string propagation in an anisotropic, cosmological background. We solve the equations of motion and the constraints by performing a perturbative expansion of the string coordinates in powers of c^2, the world-sheet speed of light.

The Model of Statecraft in Mirror for Prince Case Study: Tarikh _e_Beihaqi [PDF]
Faṣlnāmah-i Pizhūhish/hā-yi Rāhburdī-i Siyāsat, 2018 In this essay we put forward the STATECRAFT as a modern issue and at the same time we are trying to recognize its live questions and matters. So in this context for a first time we tried to study TARIKH_E_BEIHAQI as a mirror for princes' book and ...

Density Dependence of Transport Coefficients from Holographic Hydrodynamics
, 2008 We study the transport coefficients of Quark-Gluon-Plasma in finite temperature and finite baryon density. We use AdS/QCD of charged AdS black hole background with bulk-filling branes identifying the U(1) charge as the baryon number.

Are Null Results Becoming an Endangered Species in Marketing? [PDF]
, 1992 Editorial procedures in the social and biomedical sciences are said to promote studies that falsely reject the null hypothesis. This problem may also exist in major marketing journals.

SSRN Electronic Journal, 2022 Abstract We examine how the evaluation of research studies in economics depends on whether a study yielded a null result. Studies with null results are perceived to be less publishable, of lower quality, less important and less precisely estimated than studies with large and statistically significant results, even when holding constant ...

Quantum Boltzman equation study for the Kondo breakdown quantum critical point
, 2009 We develop the quantum Boltzman equation approach for the Kondo breakdown quantum critical point, involved with two bands for conduction electrons and localized fermions. Particularly, the role of vertex corrections in transport is addressed, crucial for

Improving Inferences about Null Effects with Bayes Factors and Equivalence Tests.
The journals of gerontology. Series B, Psychological sciences and social sciences, 2018 Researchers often conclude an effect is absent when a null-hypothesis significance test yields a non-significant p-value. However, it is neither logically nor statistically correct to conclude an effect is absent when a hypothesis test is not significant.
