Evaluating synthetic substitutes to reduce illegal harvesting and support species recovery
Conservation Biology, EarlyView.Abstract Providing synthetic substitutes is a widely promoted strategy to shift consumer demand away from wildlife products derived from threatened species. Yet, there is little evidence on whether product substitution prevents illegal or unsustainable harvesting and contributes to the recovery of threatened populations.

Conformally Coupled General Relativity
Universe, 2018 The gravity model developed in the series of papers (Arbuzov et al. 2009; 2010), (Pervushin et al. 2012) is revisited. The model is based on the Ogievetsky theorem, which specifies the structure of the general coordinate transformation group. The theorem

Symmetry Finder applied to the 1–3 mass eigenstate exchange symmetry
European Physical Journal C: Particles and Fields, 2021 In a previous paper, Symmetry Finder (SF) method is proposed to find the reparametrization symmetry of the state-exchange type in neutrino oscillation in matter.

Linking the Comparison and Graphical Approaches to Bipartite Matching
International Statistical Review, EarlyView.Summary Bipartite record linkage has the goal of identifying observations referring to the same individual, called coreferent observations, across two distinct non‐duplicated datasets. The two main approaches to solve this task are the Fellegi–Sunter model, which relies on pairwise comparisons of observations, and the graphical record linkage model ...

Error bounded approximate reparametrization of NURBS curves [PDF]
, 2000 journal articleThis paper reports research on solutions to the following reparametrization problem: approximate c(r(t)) by a NURBS where c is a NURBS curve and r may, or may not, be a NURBS function.

Cointegration in a MIDAS Regression
Oxford Bulletin of Economics and Statistics, EarlyView.ABSTRACT Mixed data sampling (MIDAS) cointegration models are used to analyse variables observed at different frequencies. In this paper, we start from an assumed autoregressive distributed lag (ADL) model for high‐frequency observations, and derive the resulting representation when the dependent variable is only observed at a lower frequency.

The approximate conformal mapping onto multiply connected domains
Проблемы анализа, 2019 The method of boundary curve reparametrization is generalized to the case of multiply connected domains. We construct the approximate analytical conformal mapping of the unit disk with N circular slits or an annulus with (N - 1) circular slits onto an ...

Long‐term stability of vertical bone augmentation in implant dentistry: A domain‐based review
Periodontology 2000, EarlyView.Abstract Objectives Vertical ridge deficiency remains one of the most challenging conditions in preimplant surgery. Several techniques aim to restore lost vertical alveolar height, each with specific indications and limitations. Although these procedures often yield favorable short‐term outcomes with stable bone levels, their long‐term performance is ...

PHYSICAL PROJECTIONS IN BRST TREATMENTS OF REPARAMETRIZATION INVARIANT THEORIES
, 2001 Any regular quantum mechanical system may be cast into an Abelian gauge theory by simply reformulating it as a reparametrization invariant theory. We present a detailed study of the BRST quantization of such reparametrization invariant theories within a ...

A reparametrization invariant surface ordering
, 2005 We introduce a notion of a non-abelian loop gauge field defined on points in loop space. For this purpose we first find an infinite-dimensional tensor product representation of the Lie algebra which is particularly suited for fields on loop space.
