Interest-aware influence diffusion model for social recommendation

Journal of Intelligent Information Systems, 2021
With the rapid development of social networks, the application of social relationships in recommendation systems has attracted more and more attention. The social recommendation system alleviates the problem of data sparsity by utilizing the preferences of users’ friends, so as to better model the user embedding.

Region-of-interest diffuse optical tomography system

Review of Scientific Instruments, 2016
Diffuse optical tomography (DOT) using near-infrared light is a promising tool for non-invasive imaging of deep tissue. This technique is capable of quantitative reconstruction of absorption (μa) and scattering coefficient (μs) inhomogeneities in the tissue.

Interesting Method of MR Diffusion Measurement

2007 IEEE International Conference on Signal Processing and Communications, 2007
The paper describes a newly proposed magnetic resonance (MR) method and the processing of signals being measured, with the aim of establishing the diffusion coefficients in heterogeneous materials with short relaxation times T2. The measuring method and the digital signal processing enable eliminating the effect of static magnetic field on the accuracy

Interest-Aware Information Diffusion in Evolving Social Networks

IEEE Transactions on Wireless Communications, 2018
Many realistic wireless social networks are evolving over time. While network evolution has its important influence on network performances, it is nevertheless overlooked in most existing studies on information diffusion. Motivated by this, in this paper, we investigate the delivery accuracy of interest-aware information diffusion in evolving social ...

Exit times for the diffusion risk model with debit interest

International Journal of System Assurance Engineering and Management, 2017
This paper investigates the diffusion risk model with debit interest. The Laplace–Stieltjes transform (LST) of the first exit times of the risk process is obtained. Finally, numerical examples are given to illustrate the applications of the LST of some exit times.

Jump-Diffusion Processes and the Term Structure of Interest Rates

The Journal of Finance, 1988
The term structure is investigated using an extension of the Cox, Ingersoll, and Ross model when state variables and production technologies follow jump-diffusion processes. In the presence of jump diffusions, the authors find: (1) R. Merton's multi-beta CAPM does not hold in general; (2) D.

Diffusion Process Specifications for Interest Rates

1984
Aim of this paper is the empirical investigation of several diffusion process specifications for the instantaneous interest rate, which have been recently suggested in the finance literature. We derive estimation equations for the parameters of diffusion processes with linear drift and non-constant variances.

Diffusion with memory in two cases of biological interest

Journal of Theoretical Biology, 2008
The complexity of a biological structure, such as membrane where the transport process may carry solid particles which may obstruct some of the pores, diminishing their size and making the permeability dependent on the local structure of the medium, suggests the introduction of a space-dependent diffusion constant.
