Finite mixture models have come to play a very prominent role in modelling data. The finite mixture model is predicated on the assumption that distinct latent groups exist in the population. The finite mixture model therefore is based on a categorical latent variable that distinguishes the different groups. Often in practice distinct sub-populations do not actually exist. For example, disease s...

The current study examined the function of the lateral entorhinal cortex (LEC) in a non-spatial latent learning task and a spatial latent learning task. Latent learning is the acquisition of neutral information that does not immediately influence behavior, but can be recalled and utilized when it becomes relevant to the animal. Based on previous research, it was predicted that the LEC would be ...

The multifunctional cytokine, transforming growth factor-beta (TGF beta), is found in many tissues in a latent or inactive form. The nature and composition of the latent complex can vary depending on tissue type. The release of active TGF beta from its latent complex is a potentially important mechanism for regulation of TGF beta activity. We have shown previously that osteoclasts activate late...

atypical presentation is the most common form of celiac disease (cd). although the terminologies like latent, silent and potential have expressed different aspects of clinical and pathological behaviour of cd, they also have contributed in some extent to confusion between clinicians and patients due to the multiple definitions and uncertainty around them. in the light of new advances and the di...

Our goal is to detect localized regions of excessive activity in a network, distinguishing networks that contain such regions from networks whose activity is more homogeneous. We consider inference on random graphs from a latent position model whose latent position space is a torus, using edge density and maximum degree on as test statistics. 1 Torus Latent Position Models By now, it goes witho...

this paper aims to estimate a model of demand for health insurance and medical care in iran in the presence of the heterogeneous and latent health status of individual; moreover it tests the asymmetry of information in the health insurance industry of iran. our dataset consists of whole family budget survey of 2006. the parameters of model are estimated by g.m.m method and the model used in thi...

Latent group b markers were detected in sera, in IgG preparations, and on isolated L chains from rabbits bred for homozygosity at the b locus. Serologic analysis of sera from an extended family of homozygous b4 rabbits revealed the presence of latent b allotypes in 5 of 37 sera tested. Latent b5 and b9 markers were identified; none of the sera tested contained latent b6. In two instances, the l...
