The paper assumes a theoretical-empirical interface exists between top-down (structural concepts) and bottom-up (cognitive mechanisms and socio-cultural interactions) approaches to collective memory. Both deal with collaborative group accounts, material culture such as artefacts and representational re-descriptive technologies. Anthropology has shown how communal life was based on story telling...

Darwin-inspired population thinking suggests approaching culture as a population of items of different types, whose relative frequencies may change over time. Three nested subtypes of populational models can be distinguished: evolutionary, selectional and replicative. Substantial progress has been made in the study of cultural evolution by modelling it within the selectional frame. This progres...

Models of cultural evolution study how the distribution of cultural traits changes over time. The dynamics of cultural evolution strongly depends on the way these traits are transmitted between individuals by social learning. Two prominent forms of social learning are payoff-based learning (imitating others that have higher payoffs) and conformist learning (imitating locally common behaviours)....

the fusion of medical images is very useful for clinical application. generally, the pet image indicates the function of tissue and the mri image shows the anatomy of tissue. in this article we fused mri and pet images and the purpose is adding structural information from mri to pet image. the images decomposed with curvelet transform, and then two images fused with applying fusion rules. we us...

In this paper, an approach for providing unified access to heterogeneous distributed cultural heritage collections is presented. The proposed approach is developed within the framework of the REACH Greek National Project with the overall aim to provide a web portal enabling access to different databases of cultural content with emphasis on multimedia material. In order to achieve this, the proj...

a generalization of the known results in fusion frames and $g$-frames theory to continuous fusion frames which defined by m. h. faroughi and r. ahmadi, is presented in this study. continuous resolution of the identity (cri) is introduced, a new family of cri is constructed, and a number of reconstruction formulas are obtained. also, new results are given on the duality of continuous fusion fram...

abstract  background: spondylolysis and spondylolisthesis can be associated with significant  low back pain, especially in physically active adolescents. non-operative management  is usually successful in improving symptoms, but surgical intervention is  occasionally required. the aim of this study was to determine the effect of in situ posterolateral  fusion in the treatment of refractory case...

splenogonadal fusion is a rare entity with approximately 150 reported cases until the year 2005. the entity is a rare congenital anomaly in which there is fusion of splenic and gonadal anlagen or mesonephric derivatives. splenogonadal fusion has two continuous and discontinuous types. about ten cases have been reported to be associated with bilateral cryptorchidism in literature. very few cases...
