On gradients and texture "gradients."
Journal of Experimental Psychology: General, 1984Texture gradients, systematic variations in image texture due to perspective projection of surface texture, provide information about the shape and disposition of surfaces relative to a viewer. Although this three-dimensional information is usually described in terms of mathematical relationships involving gradients of image properties (Cutting ...

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.

Electrochemically Generated Gradients
Angewandte Chemie International Edition, 2014AbstractThis review surveys recent developments in the field of electrochemically generated gradients. The gradual variation of properties, which is a key characteristic of gradients, is of eminent importance in technology, for example, directional wetting, as well as biology, for example, chemotaxis.

Accelerating gradient descent and Adam via fractional gradients
Neural Networks, 2022We propose a class of novel fractional-order optimization algorithms. We define a fractional-order gradient via the Caputo fractional derivatives that generalizes integer-order gradient. We refer it to as the Caputo fractional-based gradient, and develop an efficient implementation to compute it. A general class of fractional-order optimization methods

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.

Hydrostatically balanced gradient-formers: Programming of gradients
Analytical Biochemistry, 1980Abstract A simple, inexpensive, and flexible design of a gradient former is described, one which permits the programming of concentration gradients of several species simultaneously with a high degree of accuracy and reproducibility. The apparatus consists of a set of rectangular reservoirs whose cross-sectional areas are modified by the use of ...

Perceptual and Motor Skills, 2006
A two-dimensional view of arousal was operationalized by controlling gradient and intensity of exercise-induced arousal in two experiments with 80 undergraduate men. Significant cognitive performance decrement on a visual-search task occurred at high arousal intensity in the steep-gradient arousal conditions.

Gradient alternations and gradient attraction
The Journal of the Acoustical Society of America, 2006Many 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 ...

The site is located in a historical district of Shikumen, in the middle of "Dao Da Li". The site now occupied by an abandoned regular square modern building that was once a supermarket. Although the building has damaged the texture of the historic district, it has also been part of the history of the city for decades.
