Summary: This study suggests that hypofractionated radiation therapy alone is a feasible option for early stage esophageal squamous cell carcinoma patients. Particularly, in patients with tumor length < 3 cm, this treatment scheme shows favorable local control rates with low incidence of esophageal toxicities.

Summary: This study proposes a framework based on hybrid 2D-3D convolutional neural networks for obtaining continuous 3D retinal layer surfaces from OCT volumes. The framework works well with both full and sparse annotations and utilizes alignment displacement vectors and layer segmentation to align the B-scans and segment the layers. Experimental results show that the framework outperforms state-of-the-art 2D deep learning methods in terms of layer segmentation accuracy and cross-B-scan 3D continuity.

Summary: This paper provides a comprehensive overview of Laser Ultrasonic Testing (LUT) and its applications in composite materials. LUT is a noncontact and nondestructive technique that utilizes lasers to generate and detect ultrasonic waves. Despite challenges such as low signal-to-noise ratio and complex damage patterns in composite materials, LUT shows promise for implementation in Smart Industries and harsh industrial environments.

Summary: In this study, a tunable spherical piezoelectric transducer (TSPT) was proposed, which can adjust the electromechanical characteristics by changing the resistance, inductance, and capacitance applied to the passive piezoceramic shell. The experimental results validated the effectiveness of the TSPT, and this method has the potential to extend the working frequency range of existing piezoelectric spherical transducers.

Summary: Ultrasonic inspection of cast austenitic stainless steel (CASS) in the nuclear industry is challenging due to sound field scatter and attenuation caused by the coarse-grained microstructure. Modeling and simulation are important tools for addressing key aspects of inspections, but developing a useful and reliable CASS model is challenging. This study demonstrates a method of creating a realistic CASS model and compares it with laboratory-measured sound fields, showing promising results.

Summary: This paper investigates the monitoring of the integrity of the spherical balls inside a ball bearing using ultrasonic method. Through numerical and experimental studies on the interaction between the sphere and Rayleigh Surface Acoustic Waves (SAWs) propagating on a plane, it is found that the backgenerated wave preserves the waveform of the SAW, allowing for inference of material properties. This study is important for non-destructive testing and evaluation of ball bearings without disassembling them.

Summary: A new protocol for fabricating a microflow phantom with bifurcated geometry at a superficial region was proposed in this study. Ultrasound imaging confirmed the successful creation of the desired flow tract with bifurcation at a depth of 2-5 mm. The experiments demonstrated the validity of the proposed protocol for creating a microscale intricate flow tract with desired dimensions and depth. This new phantom will facilitate further improvement in ultrasound technologies for precise visualization of superficial complex vasculatures.

Summary: The leakage neutron spectra of Lead samples were measured using a TOF technique, and MCNP simulations with different nuclear data libraries showed that JENDL-5.0 and JEFF-3.3 libraries have better agreement with experimental data. Differences in spectra mainly stem from variations in neutron reaction channels across the libraries, with ENDF/B-VIII.0 and CENDL-3.2 libraries being overestimated in certain energy ranges.

The results show that the addition of TeO2 can enhance the glass's ability to absorb photons and fast neutrons, and effectively suppress photon buildup. These glasses also exhibit exceptional gamma radiation and fast neutron moderating abilities, making them suitable for designing lead-free, transparent, and efficient radiation protection structures.
