Summary: This research proposes a device structure modification for a doped tunnel field-effect transistor (TFET) with gate engineering to enhance performance and analyzes the impact of temperature on various parameters. The study shows that OFF-state current is more sensitive at high temperatures, while ON-state current is minimally affected by temperature variation, making the device prominent for low-power high-frequency applications.

Summary: Optical performance monitoring (OPM) is essential for managing future optical fiber communication networks, providing feedback on physical layer states to enable better network planning and diagnosis. By utilizing low-bandwidth coherent receivers and local lasers, a multiparameter OPM at intermediate nodes can scan optical spectrum, measure power, wavelength, OSNR, and other parameters for improved network performance.

Summary: This study analyzes and optimizes the performance of the printed circuit heat exchanger (PCHE). The research shows that the structural parameters of the airfoil fins have a significant impact on the flow and heat transfer performance of supercritical carbon dioxide (SCO2) in the PCHE channel. Changes in the maximum thickness, distance from the maximum thickness location to the leading-edge, and leading-edge radius affect the heat transfer and flow characteristics of the PCHE channel.

Summary: In this study, a three-dimensional computational fluid dynamics (CFD) model of diesel particulate filter (DPF) was used to investigate the influence of key structural factors on capture performance. The results show that reducing wall thickness and increasing filter diameter, filter length, and cell density per square inch (CPSI) can lead to a reduction in pressure drop and an improvement in filtration efficiency of DPF. Furthermore, the results of grey correlation analysis suggest that wall thickness is the most significant structural factor in DPF design. This work provides important reference for optimizing DPF capture performance and extending its working time.

Summary: This paper establishes the mechanical equilibrium equation of each layer of unbonded flexible risers under bending load and introduces the contact condition between layers. The bending response is divided into three stages based on the slip state of the spiral strip, and the expressions of bending moment and bending stiffness are derived. The study shows that the friction coefficient, helix angle, and number of spiral strips have an impact on the bending performance of flexible pipes.

Summary: In this study, WO3-x hydrate nanosheets with superior electrochromic properties were successfully fabricated using a template/surfactant-free solvothermal method. Films with mesostructured architecture were formed on FTO glass substrates by dip-coating process, and an analog smart window device (ASWD) was assembled. The ASWD exhibited excellent optical modulation range, switching time, coloration efficiency, and cyclic stability.

Summary: Transmission loss (TL) of a muffler is a key index for evaluating its performance, balancing acoustic properties with other factors like size and cost. Changes in structural parameters have less impact on TL at low frequencies, but are more significant at high frequencies. Among the parameters, F has the greatest effect on TL.

Summary: In this paper, a new Y-shaped labyrinth-channel drip irrigation emitter was proposed and its hydraulic performance was studied. The analysis showed that increasing the waist-arc angle improved the hydraulic performance, while decreasing the ratio of crown height to chord length also enhanced the hydraulic performance. Compared to the commonly used triangular-channel emitter, the Y-shaped emitter had better hydraulic performance.
