Surface Dye Flow Visualization: A Qualitative Method to Observe Streakline Patterns in Supersonic Flow

Flow visualization around or on a body is an important tool in aerodynamics research. It provides a method to qualitatively and quantitatively study flow structure, and it also helps researchers theorize and verify fluid flow behavior. Flow visualization can be divided into two categories: off-the-surface visualization and surface flow visualization. Off-the-surface flow visualization techniques involve determining the flow characteristics around the body of interest. They include but are not...

Classical multivariate pattern analysis predicts sensory stimuli a subject perceives from neural activity in the corresponding cortices (e.g. visual stimuli from activity in visual cortex). Here, we apply pattern analysis cross-modally and show that sound- and touch-implying visual stimuli can be predicted from activity in auditory and somatosensory cortices, respectively.

Source: Laboratories of Jonas T. Kaplan and Sarah I. Gimbel—University of Southern California Imagine the sound of a bell ringing. What is happening in the brain when we conjure up a sound like this in the "mind's ear?" There is growing evidence that the brain uses the same mechanisms for imagination that it uses for perception.1 For example, when imagining visual images, the visual cortex becomes activated, and when imagining sounds, the auditory cortex is engaged. However, to what extent are...

We demonstrate methods for the detection of architectural distortion in prior mammograms. Oriented structures are analyzed using Gabor filters and phase portraits to detect sites of radiating tissue patterns. Each site is characterized and classified using measures to represent spiculating patterns. The methods should assist in the detection of breast cancer.
FAQs
Direction, velocity, timing, and regional variation provide complementary views of a flow pattern. Direction indicates where movement is oriented, velocity describes how quickly it proceeds, and timing shows when changes occur. Regional variation reveals whether transport is consistent or differs across locations. Examining these measures together helps distinguish organized dynamics from a uniform or oversimplified description.
Flow Pattern Analysis becomes more informative when measurements are compared across conditions rather than interpreted in isolation. A change may appear as altered direction, speed, timing, or spatial distribution, and each pattern can point to a different change in system behavior. Condition-based comparisons help researchers relate motion to development, disease, treatment, or other experimental states.
It converts visible or recorded motion into measurements that can be compared across space and time. This quantitative emphasis allows researchers to examine regional differences and changes between conditions, instead of relying only on whether a structure or signal appears present. The result is a more systematic interpretation of transport-related imaging and physiological data.
An analysis generally begins by identifying the substance or signal of interest and examining its movement across relevant regions and time points. Researchers then characterize direction, velocity, timing, and regional variation, organize the measurements into flow patterns, and compare them across conditions. This workflow links motion data with the anatomical or physiological context needed to interpret the result.
It can be used to study organized movement of substances or signals in complex systems, including blood and cerebrospinal fluid in brain-related research. Because the same analytical logic addresses spatial direction, velocity, timing, and regional differences, it supports broader investigation of transport dynamics rather than one isolated observation.
Analysis of blood or cerebrospinal fluid flow can contribute to studies of neurovascular function and fluid circulation. Comparing patterns across development, disease, or treatment may show how these processes vary with condition. Linking the measurements to neural structure and function also helps researchers interpret imaging and physiological findings in a more integrated way.
