Scale invariance, either in space or in time, has been shown in many papers to characterize earthquake distributions. Unfortunately, only little work has been dedicated to looking at the general space-time scaling invariance of seismicity systems, even though a better understanding of how the two domains (spatial and temporal) link together could help to the development of the stochastic dynami...

BACKGROUND This cross validation study examined the reliability of the Multidimensional Pain Inventory (MPI) and the stability of the Multidimensional Pain Inventory Classification System of the empirically derived subgroup classification obtained by cluster analysis in chronic musculoskeletal pain. Reliability of the German Multidimensional Pain Inventory was only examined once in the past in ...

The role of service quality in fostering the growth of mHealth services has gained much attention in the academic and practitioner communities. However, empirical research in this area has been beset by inadequate conceptualization and the lack of a validated scale. This study addresses these limitations by theoretically conceptualizing and empirically validating a multidimensional service qual...

OBJECTIVE To evaluate the validity of the Ghent Multidimensional Somatic Complaints Scale (GMSCS) in a Clinical Sample. METHOD Three hundred fifty-four non-clinical subjects and 151 clinical patients completed the GMSCS, an 18-item five-factorial scale for the assessment of somatic complaints. RESULTS The five-factorial structure was reliable and valid in the non-clinical as well as the cli...

Recent studies of properties of various biological networks revealed that many of them display scale free characteristics. Since the theory of scale free networks is applicable to evolving networks, one can hope that it provides not only a model of a biological network in its current state but also some insight into the evolution of the network. Here, we re-investigate the probability distribut...

In the past decades linear scale-space theory was derived on the basis of various axiomatics. In this paper we revisit these axioms and show that they merely coincide with the following physical principles, namely that the image domain is a Galilean space, that the total energy exchange between a region and its surrounding is preserved under linear ltering and that the physical observables shou...

In this paper, we propose a new dwindling multidimensional filter second-order line search method for solving large-scale unconstrained optimization problems. Usually, the multidimensional filter is constructed with a fixed envelope, which is a strict condition for the gradient vectors. A dwindling multidimensional filter technique, which is a modification and improvement of the original multid...
