THRESHOLD EFFECTS AND PERTURBATIVE UNIFICATION [PDF]

open access: yesInternational Journal of Modern Physics A, 1995
We discuss the effect of the renormalization prescription in the computation of the unification point for running coupling constants. We explore the effects of threshold crossing on the β functions. We compute the running of the coupling constants of the Standard Model, between mz and Mp, using a mass-dependent subtraction procedure, and then compare ...

Threshold Effects in Cointegrating Relationships* [PDF]

open access: yesOxford Bulletin of Economics and Statistics, 2006
AbstractIn this paper, we introduce threshold‐type nonlinearities within a single‐equation cointegrating regression model and propose a testing procedure for testing the null hypothesis of linear cointegration vs. cointegration with threshold effects. Our framework allows the modelling of long‐run equilibrium relationships that may change according to ...

Threshold resummation for computing large-x parton distribution through large-momentum effective theory

open access: yesJournal of High Energy Physics, 2023
Parton distribution functions (PDFs) at large x are poorly constrained by high-energy experimental data, but extremely important for probing physics beyond standard model at colliders.

The Price of Cost-Effectiveness Thresholds

open access: yesSSRN Electronic Journal, 2022
Health systems around world are increasingly adopting cost-effectiveness (CE) analysis to inform decisions about access and reimbursement. We study how CE thresholds imposed by a health plan for granting reimbursement affect drug producers pricing incentives and patients access to new drugs. Analysing a sequential pricing game between an incumbent drug

Cost-effectiveness thresholds or decision-making threshold: a novel perspective

open access: yesCost Effectiveness and Resource Allocation, 2023
AbstractThe use of multiple cost-effectiveness thresholds in pharmacoeconomic evaluation is a hotly debated topic in the international academic community. This study analyzed and discussed thresholds in the context of pharmacoeconomic evaluation and reimbursement decision-making.

Effective range function below threshold [PDF]

open access: yes, 2000
We demonstrate that the kernel of the Lippmann-Schwinger equation, associated with interactions consisting of a sum of the Coulomb plus a short range nuclear potential, below threshold becomes degenerate.

Cost–effectiveness thresholds: pros and cons [PDF]

open access: yesBulletin of the World Health Organization, 2016
Cost-effectiveness analysis is used to compare the costs and outcomes of alternative policy options. Each resulting cost-effectiveness ratio represents the magnitude of additional health gained per additional unit of resources spent. Cost-effectiveness thresholds allow cost-effectiveness ratios that represent good or very good value for money to be ...

The facilitation effect and language thresholds [PDF]

open access: yesFrontiers in Psychology, 2014
Lechner and Siemund (2014) set out to determine whether bilinguals have an advantage for learning additional languages over monolinguals, purporting to evaluate the Threshold Hypothesis of Cummins (1979a) in this context. The study investigated the attainment of English literacy by Turkish-German, Vietnamese-German, and RussianGerman simultaneous and ...
