Summary
A new wearable ultrasound stabilization system for speech research ensures precise tongue imaging. This lightweight, 3D-printable device allows natural jaw and head movement while preventing transducer instability.
Area of Science:
- Biomechanics
- Speech Science
- Medical Imaging
Background:
- Ultrasound imaging of the tongue is crucial for speech research.
- Maintaining ultrasound transducer stability is essential for accurate speech recording and analysis.
- Existing methods may restrict natural speech articulation or interfere with other measurement systems.
Purpose of the Study:
- To develop and evaluate a novel, wearable ultrasound transducer stabilization system for speech research.
- To ensure the system allows for flexible jaw motion and free head movement.
- To create a non-metallic system compatible with other articulometry systems.
Main Methods:
- An iterative design process was used to create a lightweight, 3D-printable wearable system.
- The system was designed to be completely non-metallic to avoid signal interference.
- A motion study was conducted on the final prototype to assess its performance.
Main Results:
- The developed system effectively stabilizes the ultrasound transducer during speech tasks.
- The system allows for flexible jaw motion and free head movement.
- Motion analysis confirmed minimal transducer rotation (1.25°) and translation (2.5 mm), within acceptable limits.
Conclusions:
- The presented wearable ultrasound transducer stabilization system is effective for speech research.
- The non-metallic, 3D-printable design offers a stable, non-interfering solution for tongue imaging.
- This system facilitates accurate, co-registered data collection with other articulometry systems.

Protons and neutrons, collectively called nucleons, are packed together tightly in a nucleus. With a radius of about 10−15 meters, a nucleus is quite small compared to the radius of the entire atom, which is about 10−10 meters. Nuclei are extremely dense compared to bulk matter, averaging 1.8 × 1014 grams per cubic centimeter. If the earth’s density were equal to the average nuclear density, the earth’s radius would be only about 200 meters.

Intact DNA strands can be found in fossils, while scientists sometimes struggle to keep RNA intact under laboratory conditions. The structural variations between RNA and DNA underlie the differences in their stability and longevity. Because DNA is double-stranded, it is inherently more stable. The single-stranded structure of RNA is less stable but also more flexible and can form weak internal bonds. Additionally, most RNAs in the cell are relatively short, while DNA can be up to 250 million...

The time response of a linear time-invariant (LTI) system can be divided into transient and steady-state responses. The transient response represents the system's initial reaction to a change in input and diminishes to zero over time. In contrast, the steady-state response is the behavior that persists after the transient effects have faded.
The stability of an LTI system is determined by the roots of its characteristic equation, known as poles. A system is stable if it produces a bounded...

01:31Transducer Mechanism: Nuclear Receptors
2.5K
Nuclear receptors, or NRs, are unique transcription factors that regulate gene transcription and affect the cellular pathways involved in reproduction, development, or metabolism. Their ability to be stimulated by small lipophilic ligands and control vital cellular processes makes them ideal drug targets. Nearly 10-15% of currently prescribed drugs target these receptors.
About 48 different soluble family members of nuclear receptors are identified that can be divided into two main classes:

In mechanical engineering, the stability of systems under various forces is critical for designing durable and efficient structures. One fundamental way to explore these concepts is by analyzing systems like two rods connected at a pivot point, O, with a torsional spring of spring constant k at the pivot point. This system is similar in appearance to a scissor jack used to change tires on a car. In this case, the arms of the linkage (equivalent to the rods in this system) are entirely vertical,...
