Natural density and probability, constructively

open access: yesReports on Mathematical Logic, 2020
We give a constructive account of the frequentist approach to probability, by means of natural density. Then we discuss some probabilistic variants of the Limited Principle of Omniscience.

Natural units for nuclear energy density functional theory [PDF]

open access: yesPhysical Review C, 2010
Naive dimensional analysis based on chiral effective theory, when adapted to nuclear energy density functionals, prescribes natural units and a hierarchy of contributions that could be used to constrain fits of generalized functionals. By applying these units, a large sample of Skyrme parametrizations is examined for naturalness, which is signaled by ...

Density Peak Clustering Algorithm Based on Relative Density [PDF]

open access: yesJisuanji gongcheng, 2023
When the density peak clustering algorithm deals with datasets with uneven density,it is easy to divide the low-density clusters into high-density clusters,divide the high-density clusters into multiple sub-clusters,and exists the error propagation ...

High-Density Lipoproteins: Nature’s Multifunctional Nanoparticles [PDF]

open access: yesACS Nano, 2016
High-density lipoproteins (HDL) are endogenous nanoparticles involved in the transport and metabolism of cholesterol, phospholipids, and triglycerides. HDL is well-known as the "good" cholesterol because it not only removes excess cholesterol from atherosclerotic plaques but also has anti-inflammatory and antioxidative properties, which protect the ...

Density-Distance Outlier Detection Algorithm Based on Natural Neighborhood

open access: yesAxioms, 2023
Outlier detection is of great significance in the domain of data mining. Its task is to find those target points that are not identical to most of the object generation mechanisms.

Peak Density Clustering Algorithm Combining Natural and Shared Nearest Neighbor

open access: yesJisuanji kexue yu tansuo, 2021
The clustering by fast search and find of density peaks (DPC) has the advantages of no iteration and fewer parameters, but it still has some shortcomings: the need to manually select the cutoff distance parameter and the processing effect is not good on ...

Natural Optical Activity from Density-Functional Perturbation Theory

open access: yesPhysical Review Letters, 2023
We present an accurate and computationally efficient first-principles methodology to calculate the natural optical activity. Our approach is based on the long-wave density-functional perturbation theory and includes self-consistent field (SCF) terms naturally in the formalism, which are found to be of crucial importance.

Optimized Density Peak Clustering Algorithm by Natural Reverse Nearest Neighbor

open access: yesJisuanji kexue yu tansuo, 2021
The density peak clustering algorithm is a density based clustering algorithm. The shortcomings of the density peak clustering algorithm are sensitive to parameters and poor clustering results on complex manifold data sets.

Natural orbital functional theory and pairing correlation effects in electron momentum density [PDF]

open access: yes, 2014
Occupation numbers of natural orbitals capture the physics of strong electron correlations in momentum space. A Natural Orbital Density Functional Theory based on the antisymmetrized geminal product provides these occupation numbers and the corresponding

Efeito da pré-molhagem do agregado nas propriedades das argamassas com agregado reciclado deconcreto e agregado leve [PDF]

open access: yes, 2019
This paper examines the suitability of partially replacing natural aggregate, sand, (NA) with recycled concrete aggregate (RCA) or lightweight aggregate (LWA) in mortars, under the hypothesis that pre-wetting aggregates would produce improvement in ...
