Assessment of Salivary Levels of the RANKL and RANK in Patients with Healthy Gingiva on Reduced Periodontium Versus Periodontitis: An Analytical Cross-Sectional Study

open access: yesDental Hypotheses, 2023
Introduction: We aimed to compare the changes in the two salivary biomarkers, RANKL and RANK, among patients with healthy gingiva on reduced periodontium versus generalized periodontitis stages II and III.

Ranking functions and rankings on languages

open access: yesArtificial Intelligence, 2006
AbstractThe Spohnian paradigm of ranking functions is in many respects like an order-of-magnitude reverse of subjective probability theory. Unlike probabilities, however, ranking functions are only indirectly—via a pointwise ranking function on the underlying set of possibilities W—defined on a field of propositions A over W.

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada

open access: yesPopulation Ecology, EarlyView.
We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

Some Ultimate Limits on the Measurement of Surfaces Using Stylus Techniques

open access: yesMeasurement + Control, 1975
In recent years the use of stylus instruments has progressed from mainly engineering applications into research fields. This is mainly due to the development of highly sensitive instruments. Some results of this work are shown together with the limits of

High rank linear syzygies on low rank quadrics [PDF]

open access: yes, 2010
We study the linear syzygies of a homogeneous ideal I in a polynomial ring S, focusing on the graded betti numbers b_(i,i+1) = dim_k Tor_i(S/I, k)_(i+1).

Network topology drives population temporal variability in experimental habitat networks

open access: yesPopulation Ecology, EarlyView.
Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...

Characterizations of matrix equalities involving the sums and products of multiple matrices and their generalized inverse

open access: yesElectronic Research Archive, 2023
It is common knowledge that matrix equalities involving ordinary algebraic operations of inverses or generalized inverses of given matrices can be constructed arbitrarily from theoretical and applied points of view because of the noncommutativity of the ...
