Summary: Manual materials handling is a significant risk factor for musculoskeletal injuries in many workplaces. This study aimed to develop a lifting capacity prediction model for construction workers based on muscle strength and endurance. Through the assessment of 65 construction workers, the study found that age, BMI, grip strength, flexibility, prone plank, and trunk lateral flexor endurance tests significantly influenced lifting capacity. Therefore, a regression model was developed to aid in easy estimation of lifting capacity among construction workers, which could be administered by site supervisors or managers with minimal skills. This could help in decision-making during pre-placement or return to work evaluations, thereby reducing the incidence of low back disorders.

Summary: A novel time-frequency analysis method called MLST is proposed in this study to enhance the energy concentration of TFR for fast-varying instantaneous frequency and strong noise signals of rotating machinery through multiple lifting operations. The method aims to provide promising support for rotating machinery fault diagnosis through readable TFR.

Summary: Overexertion in lifting tasks is a major cause of occupational injuries. This study proposed using tactile gloves to predict the load weight, achieving a predicted R-squared of 0.821 and a mean absolute error of 1.579 kg with a ResNet 18 regression model. The importance of each sensor and hand force exertion pattern during lifting were also determined.

Summary: Luminance edges in retinal images are suggested to be potential cues for glossiness perception, but their causal relationship is still unclear. Enhancing sub-band contrast can significantly increase perceived glossiness, with different spatial frequencies influencing glossiness perception under different conditions.

Summary: Two silicon-containing eugenol-based benzocyclobutene monomers were synthesized using a solvent-free hydrosilylation reaction. The resulting polymers showed high thermostability, good transparency, and hydrophobicity. In particular, P3 demonstrated excellent dielectric properties and flame retardancy, indicating the potential application of eugenol-based low-dielectric materials in the field of microelectronics encapsulation resins.

Summary: A growing body of research supports weight lifting as an effective intervention in the psychological treatment of trauma and trauma-related disorders. However, there are barriers to participation in weight lifting, especially among those impacted by trauma. By utilizing interviews and surveys, this study aims to design a trauma-informed weight lifting program for trauma survivors and provide guidelines for personal trainers. The results contribute to reducing barriers and professionalizing personal trainers in trauma-related competencies.

Summary: This study investigates specific schemes regarding how the output of arm-locking is further processed by the TDI algorithm and proposes a real-time acousto-optic modulation scheme to compensate for noise due to optical bench motion. The evaluation of sensitivity curves indicates that the resulting performance meets the requirement of the Laser Interferometer Space Antenna detector.

Summary: Virtual reality has the potential to enable remote collaborative work from anywhere, but developing it into a platform for natural interaction and immersive collaboration requires stable experience. This study conducted two experiments to evaluate participant sensitivity to tick rate in virtual reality, and found that velocity and digital medium significantly affected perceived smoothness of motion. They built and validated a model that can predict participant perception of tick rate under different conditions, allowing networks to optimize participant experience without adding unnecessary load.

Summary: This article presents a high-performance silicon nitride photonic integrated circuit platform that operates at visible wavelengths and is accessible through the commercial foundry, LIGENTEC. The article measures propagation losses across the visible spectrum from 450 nm to 850 nm. For wavelengths above 630 nm, the losses are <1 dB/cm in TE and <0.5 dB/cm in TM. In addition, sets of single mode waveguide-coupled ring resonators across three separate chips were tested and analyzed. The article provides an analysis of the loss and coupling, considering the bus-ring coupling gap and waveguide width. High confinement, low loss devices based on chip-scale silicon nitride are becoming increasingly important for the next generation of integrated optical devices operating at visible wavelengths.

Summary: The study focuses on utilizing Barker sequences and phase masks to create highly selective windows in optical transfer functions (OTF). By exploring various configurations, it is found that using a pair of adjacent, non-overlapping Barker masks is a good choice. The proposed method is successfully applied to identify envelopes in carrier frequency photographs.
