Abstract: This paper studies the joint limiting behavior of extreme eigenvalues and trace of large sample covariance matrix in a generalized spiked population model, where the asymptotic regime is such that the dimension and sample size grow proportionally. The form of the joint limiting distribution is applied to conduct Johnson-Graybill-type tests, a family of approaches testing for signals i...

Proposing a certain notion of logical completeness as a novel quality criterion for ontologies, we identify and characterise a class of logical propositions which naturally extend domain and range restrictions commonly known from diverse ontology modelling approaches. We argue for the intuitivity of this kind of axioms and show that they fit equally well into formalisms based on rules as well a...

For a noisy quantum channel, a quantum error correcting code exists if and only if the joint higher rank numerical ranges associated with the error operators of the channel is non-empty. In this paper, geometric properties of the joint higher rank numerical ranges are obtained and their implications to quantum computing are discussed. It is shown that if the dimension of the underlying Hilbert ...

Spondyloepiphyseal dysplasia tarda with progressive arthropathy (SEDT-PA) is a rare autosomal recessive skeletal dysplasia affecting primarily the articular cartilage. Here we present a nine-year-old girl from Middle Anatolia (Sivas) with SEDT-PA. Her complaints were pain and progressive deformity of the joints. She had a short stature with increased thoracic kyphosis and lumbar lordosis. The r...

We give a new generalization of the spt-function of G.E. Andrews, namely Sptj(n), and give its combinatorial interpretation in terms of successive lower-Durfee squares. We then generalize the higher order spt-function sptk(n), due to F.G. Garvan, to jsptk(n), thus providing a two-fold generalization of spt(n), and give its combinatorial interpretation.

botulinum toxin a (bta) inhibits presynaptic release of acetylcholine at the neuromuscular junction and has reportedly been successful in the treatment of spastic disorders.to evaluate the effect of botulinum toxin on cerebral palsied children with spastic or mixed type of the disease, especially those patiens having spasticity as a cardinal symptom without joint contracture, we designed the fo...

BACKGROUND Generalized joint hypermobility is a highly prevalent condition commonly associated with joint injuries. The current literature has conflicting reports of the risk of joint injury in hypermobile sporting participants compared with their nonhypermobile peers. Systematic reviews have not been conclusive and no meta-analysis has been performed. PURPOSE This review was undertaken to de...

Flexibility in motor actions can be defined as variability in the use of degrees of freedom (e.g., joint angles in the arm) over repetitions while keeping performance (e.g., fingertip position) stabilized. We examined whether flexibility can be increased through enlarging the joint angle range during practice in a manual obstacle-avoidance target-pointing task. To establish differences in flexi...

background: in this feasibility study, a mechanically loaded in-vitro tissue culture model of joint morphogenesis using the isolated lower extremity of the 8 day old chick embryo was developed to assess the effects of mechanical loading on joint morphogenesis. methods: the developed in-vitro system allows controlled flexion and extension of the chick embryonic knee with a range of motion of 20 ...
