On generalized gradients

ZOR Zeitschrift f�r Operations Research Methods and Models of Operations Research, 1992
Let \(S^{n-1}=\{g\in\mathbb{R}^ n: \| g\|=1\}\) be the Euclidean sphere in \(\mathbb{R}^ n\). Let \(H:=(L^ 2(S^{n- 1},\lambda),\langle\cdot,\cdot\rangle)\) be the Hilbert space of square- integrable functions on \(S^{n-1}\) with respect to the Lebesgue measure \(\lambda\) in which the inner product is canonically given.

Patterning Gradients

2014
Surface-chemical and -morphological gradients can be extremely useful in cell-biological research as high-throughput screening tools-for example, exposing a given set of cells to many different surface conditions at once, under identical ambient conditions, in order to monitor cell behavior such as proliferation or specific gene expression.

Gradient alternations and gradient attraction

The Journal of the Acoustical Society of America, 2006
Many phonological alternations have been shown to be sensitive to lexical ‘‘gradient attraction,’’ defined by Burzio [‘‘Surface-to-surface morphology: When your representations turn into constrainsts,’’ Rutgers Optimality Archive ♯341-0999 (http://roa.rutgers.edu) (1998)] as follows: (A) The overall structure of a word W (in both phonological and ...

Gradient-Free Gradient Boosting [PDF]

open access: possible, 2020
Motivated by applications in fraud detection, this dissertation is concerned about model selection in predictive models where the correct ranking of observations has to be predicted. For this, the thesis starts by proving the asymptotic linearity of a whole family of regularized M-estimators which covers for example the Lasso.

Power of gradients

Catheterization and Cardiovascular Interventions, 2017
Key Points Patients with high baseline gradients benefit most after TAVR. In severe symptomatic aortic stenosis, every 10 mm Hg increase in mean gradient has 20% reduction in mortality after TAVR. Low gradient severe aortic stenosis continues to be a clinical cohort with variable benefit from TAVR.

Gradient Hydrogels

2020
Gradient hydrogels represent a pivotal and expanding direction of three-dimensional cell culture. Since various types of gradients play an important role in physiological and pathological processes in vivo, recreation of these gradients in vitro allows a better understanding of cellular behavior, intercellular and cell-matrix interactions.
