Vacuum Energy Sequestering: The Framework and Its Cosmological Consequences [PDF]

open access: yes, 2014
Recently we suggested a reformulation of General Relativity which completely sequesters from gravity {\it all} of the vacuum energy from a protected matter sector, assumed to contain the Standard Model.

Oscillator phase noise: a tutorial [PDF]

open access: yes, 2000
Linear time-invariant (LTI) phase noise theories provide important qualitative design insights but are limited in their quantitative predictive power.

Parameter Degeneracy in Neutrino Oscillation -- Solution Network and Structural Overview --

open access: yes, 2010
It is known that there is a phenomenon called "parameter degeneracy" in neutrino oscillation measurement of lepton mixing parameters; A set of the oscillation probabilities, e.g., P(nu_mu --> nu_e) and its CP-conjugate P(bar{nu}_mu --> bar{nu}_e) at a ...

Symmetries and time operators [PDF]

open access: yes, 2010
All covariant time operators with normalized probability distribution are derived. Symmetry criteria are invoked to arrive at a unique expression for a given Hamiltonian.

Quantum Histories and Quantum Gravity

open access: yes, 2009
This paper reviews the histories approach to quantum mechanics. This discussion is then applied to theories of quantum gravity. It is argued that some of the quantum histories must approximate (in a suitable sense) to classical histories, if the correct ...

Ordinal proportional cost sharing [PDF]

open access: yes, 2002
We consider cost sharing problems with variable demands of heterogeneous goods. We study the compatibility of two axioms imposed on cost sharing methods: ordinality and average cost pricing for homogeneous (ACPH) goods.

Investigating the Relative Impact of Different Sources of Measurement Non-Equivalence in Comparative Surveys

open access: yesSurvey Research Methods, 2020
Different factors are known to affect the comparability of multinational, multicultural and multiregional (‘3MC’) survey data. These include factors relevant to the design of the questionnaire in different contexts (such as cultural differences in how a

Invariant measures of the pair: state, approximate filtering process [PDF]

open access: yesColloquium Mathematicum, 1991
The paper contains a proof and discussion of a theorem related to a problem in discrete time filtering which may be summarized as follows. The state is a Markov process with an initial law \(\nu\). The filter is then also Markov. It is known that, if the state has a unique invariant measure, then, under certain conditions, the filter has in turn a ...

Light scalar at LHC: the Higgs or the dilaton?

open access: yes, 2007
It is likely that the LHC will observe a color- and charge-neutral scalar whose decays are consistent with those of the Standard Model (SM) Higgs boson. The Higgs interpretation of such a discovery is not the only possibility.
