Convection-enhanced delivery (CED) has been proposed as a treatment option for a wide range of neurological diseases. In order to prepare health care professionals for adoption of CED, accessible training models are needed. We describe the use of agarose gel as such a model of the human brain for testing, research, and training.

Source: Jose Roberto Moreto, Gustaaf Jacobs and Xiaofeng Liu, Department of Aerospace Engineering, San Diego State University, San Diego, California The delta wing, shown in Figure 1D, is a popular design in high-speed airplanes due to its superb performance in transonic and supersonic flight regimes. This type of wing has a small aspect ratio and high sweep angle, which reduces drag at high subsonic, transonic and supersonic flight regimes. The aspect ratio is defined as the wing span divided...

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Detected edges serve as spatial guides by identifying intensity changes that may indicate meaningful boundaries. Enhancement can then vary by location, focusing sharpening or reconstruction near those transitions while making fewer changes in smoother regions. This selectivity helps preserve important structures and limits unnecessary noise amplification in areas without strong visual boundaries.
The enhancement decision depends on where intensity transitions are detected. When a relevant boundary is represented clearly, sharpening or reconstruction can remain concentrated around the associated structure. In engineering images, that localization supports more faithful visual boundaries, which can improve interpretation and provide stronger inputs for later measurement or object-recognition steps.
Unlike an approach that alters an image broadly, edge-guided enhancement uses structural information to distinguish boundary regions from smoother content. This creates a controlled tradeoff: details near important transitions can become more visible without applying the same degree of alteration everywhere. The intended outcome is improved clarity with less risk of amplifying noise across uniform areas.
Its value lies in connecting visual improvement with structural reliability. Clearer boundaries can make inspection images easier to interpret and help automated systems distinguish objects or regions. The same principle supports medical and scientific visualization, remote sensing, and computer vision, where boundary information influences how structures, targets, or measured regions are understood.
A typical workflow first identifies intensity transitions with an edge detector. Those detected locations then guide selective sharpening or reconstruction in neighboring regions, while smoother areas receive limited modification. Engineers can use the resulting image for clearer inspection or visualization, and the structurally focused processing can produce more reliable input for subsequent measurement or recognition tasks.
Edge-guided enhancement can support clearer inspection images, medical and scientific visualization, remote sensing, and computer vision systems. These applications benefit when boundaries must remain visible for interpretation or automated analysis. By concentrating changes around structural transitions, the technique can improve the readability of relevant features and support more dependable object recognition or measurement inputs.
