In Citrus L. sp., specific root length of whole root systems has been correlated positively with root hydraulic conductivity, but there is little mechanistic understanding of the causes for this association. The hydraulic conductivity of individual roots in relation to root anatomical characteristics in seedlings of three citrus rootstocks [sour orange (SO) (Citrus aurantium L.), trifoliate ora...

The idiopathic inflammatory myopathies (IIMs) are a heterogeneous group of chronic muscle disorders, typically displaying infiltrating T cells in skeletal muscle tissue and classified into polymyositis, dermatomyositis and sporadic inclusion body myositis. Several studies involving both humans and animal models point towards a role for T cells in the pathogenesis of IIMs, however, the precise p...

In Deutschland ist die Wissenschaftslandschaft starken Veränderungen ausgesetzt. Dazu gehört neben der wachsendenWettbewerbsorientierung, wie sie die Exzellenzinitiative (und mit ihr die internationalen Peers, die nach mehr Genderorientierung verlangten) noch einmal verstärkt hat, auch die Bewältigung des demographischen Wandels. Immer mehr rückt zudem der Beitrag der Hochschulen als Akteurinne...

Purpose To study the capabilities of a novel scoring balloon concept in the recanalization of chronic iliofemoral venous occlusions and the impact on the periprocedural pain management concept. Materials and Methods A novel scoring balloon designed for problematic arterio-venous access stenosis was utilized for the recanalization of chronic iliofemoral occlusions. Severe pain during dilatation ...

The design of a pitch tracking system for noisy speech is a challenging and yet unsolved issue due to the association of "traditional" pitch determination problems with those of noise processing. We have developed a multi-channel pitch determination algorithm (PDA) that has been tested on three speech databases (0dB SNR telephone speech, speech recorded in a car and clean speech) involving fift...

Computing the eigenvalues and eigenvectors of a band or block tridiagonal matrix is an important aspect of various applications in Scientific Computing. Most existing algorithms for computing eigenvectors of a band matrix rely on a prior tridiagonalization of the matrix. While the eigenvalues and eigenvectors of tridiagonal matrices can be computed very efficiently, the preceding tridiagonaliza...

Study on the Response Time of Direct Injection Systems for Variable Rate Application of Herbicides Progress in the technology of weed detection using cameras combined with image processing requires improvements in spray technology. Spraying systems of current design distribute herbicides uniformly across the field. Applying the chemical agents only at locations with weeds according to the indic...

Through the analysis of research experiences in Didactics of Mathematics data have been compared both with the implicative analysis of Gras and with the factorial analysis of correspondences. The results of this comparison highlighted that implicative analysis, when supplementary variables are introduced, proves to be more incisive in the reading of the contingency. Factorial analysis, instead,...

While research has shown that having a ‘‘good’’ job significantly promotes formal volunteering, we have limited knowledge of how this paid work-tovolunteer work relationship may differ between men and women. Based on the gender-identification spillover theory, we hypothesize that because of the societal expectations that women should be caring, giving and communal, positive job traits such as a...

Standard architectures favor sequential processes for the semantic and syntactic part of natural language generation. Some semantic decisions, however, require information from the syntactic part, as is shown at the example of translating English gerunds into German. As a solution to this problem, a model is proposed in which syntactic and semantic modules work in parallel, computing preference...
