AI Article Synopsis
- A low-cost training model for parotid surgery was created using a 3D-printed skeleton, silicone soft tissue, and a facial nerve simulation that uses copper wire to signal instrument contact.
- The model was validated through surveys assessing its face and content validity after residents performed a simulated superficial parotidectomy following a video demo.
- Results showed faculty scored higher than residents on the simulation, and both groups agreed the model could greatly benefit junior residents in their training.
Article Abstract
We present the development and validation of a low-cost novel model for training of parotid surgery. The model consists of a 3-dimensionally printed skeleton, silicone-based soft tissue, and facial nerve replicated with copper wire, circuited to indicate contact with instruments. The face validity of the simulator was evaluated with a 21-item 5-point Likert survey. Content validity was evaluated through a survey completed by the trainees after their first live parotidectomy following the simulation. Twelve residents and 6 faculty completed the simulated procedure of superficial parotidectomy after watching a video demonstration. Completion of 16 surgical steps evaluated by this model was graded for each participant. The mean ± SD total assessment score for faculty was 15.83 ± 0.41, as compared with 13.33 ± 2.06 for residents ( = .0081). The simulator as a training tool was well received by both faculty and residents (5 vs 4, = .0206). Participants strongly agreed that junior residents would benefits from use of the model.

TCBGY net for enhanced wear particle detection in ferrography using self attention and multi scale fusion.

The intelligent identification of wear particles in ferrography is a critical bottleneck that hampers the development and widespread adoption of ferrography technology. To address challenges such as false detection, missed detection of small wear particles, difficulty in distinguishing overlapping and similar abrasions, and handling complex image backgrounds, this paper proposes an algorithm called TCBGY-Net for detecting wear particles in ferrography images. The proposed TCBGY-Net uses YOLOv5s as the backbone network, which is enhanced with several advanced modules to improve detection performance.

Department of Chemistry, University of Washington, Box 351700, Seattle, Washington, 98195, USA.
Trigger valves are fundamental features in capillary-driven microfluidic systems that stop fluid at an abrupt geometric expansion and release fluid when there is flow in an orthogonal channel connected to the valve. The concept was originally demonstrated in closed-channel capillary circuits. We show here that trigger valves can be successfully implemented in open channels.

Department of Computer Science, Birzeit University, P.O. Box 14, Birzeit, West Bank, Palestine.
Accurate classification of logos is a challenging task in image recognition due to variations in logo size, orientation, and background complexity. Deep learning models, such as VGG16, have demonstrated promising results in handling such tasks. However, their performance is highly dependent on optimal hyperparameter settings, whose fine-tuning is both labor-intensive and time-consuming.
