2. Design, modeling, and performance analysis of a 2-DOF pneumatic flexible wrist with controllable braking torque

   by Hongbo Liu, Shuo Wang, Wenpeng Xu

   To address the structural complexity and limited compliance of traditional rigid robotic wrists, as well as the absence of adjustable stiffness in soft wrists designed primarily for flexibility, a two-degree-of-freedom (2-DOF) pneumatic flexible wrist with controllable braking torque was developed. The wrist comprises three circumferentially arranged pneumatic actuators connected in parallel around a central pneumatic cross-hinge brake, enabling multidirectional pivoting, while the braking torque can be adjusted according to task requirements for pose stabilization. This configuration combines the high stiffness required for posture maintenance during braking with compliant actuation during motion. Theoretical models of the wrist pivot angle, pivoting direction, and braking torque were established. The pivot-angle model was empirically calibrated using the measured pivot-angle data, while the pivoting-direction and braking-torque models were validated experimentally. Mechanical performance was evaluated under constant-friction-torque and constant-pivot-angle conditions, and empirical relations were obtained by fitting the experimental data. A three-dimensional motion-capture system was also used to characterize the dynamic response under different braking conditions and excitation signals. Under the present experimental conditions, the results show that the wrist exhibits high compliance and enables continuous omnidirectional pivoting with a maximum single-axis pivot angle of 45.2°. The pneumatic cross‑hinge brake achieves multidirectional braking with continuously adjustable torque, reaching a maximum braking torque of 0.842 N·m under brake-only actuation at 0.35 MPa. During coordinated actuation–braking operation, the wrist’s overall resistance to external loads increased by a factor of 4.98 compared with its unpressurized initial state. This composite load-resisting capacity originates from the combined effects of the pneumatic actuators and the central brake.
3. Association between TyG‑BMI and repeat percutaneous coronary intervention (PCI) risk: exploratory stratification by glucose metabolism status

   Most patients undergoing percutaneous coronary intervention (PCI) are diagnosed with coronary heart disease (CHD). The triglyceride glucose‑body mass index (TyG‑BMI) has been reported to be associated with CHD. This study aimed to investigate the association between TyG‑BMI and the risk of repeat PCI among post‑PCI patients, with additional exploratory stratification analyses according to glucose‑metabolism status. Data for this study were derived from resident health‑record follow‑up records of Yipeng Community Health Service Center, covering January 2015 to January 2025. Logistic regression models and restricted cubic spline (RCS) were used to evaluate the association between TyG‑BMI and the risk of repeat PCI among post‑PCI patients, with exploratory stratification by glucose‑metabolism status. Logistic regression and restricted cubic spline analyses showed no significant linear or nonlinear association between TyG‑BMI and repeat PCI (OR=0.999,95%CI:0.994 ~ 1.003, P = 0.534; nonlinear χ² = 0.91, df = 3, P = 0.8223). Stratified analyses by glucose metabolism status also revealed no significant correlation in any stratum(P > 0.05). No independent association between TyG‑BMI and repeat PCI was identified in post‑PCI patients, even within different glucose‑metabolism strata. Relevant findings require further verification in larger prospective cohorts.

5. Emotional synchrony in family networks is linked to adolescent well-being in daily life

   Family emotional processes play a central role in adolescent well-being, yet most research relies on dyadic or static approaches that do not capture the dynamic, system-level nature of family emotional life. In a sample of adolescents (ages 12–17), mothers, and fathers (N = 120; 2,365 assessments), constituting 40 family triads, we used ecological momentary assessment and a dynamic network approach to estimate how emotions fluctuate over time and co-vary across family members within each system. Emotional synchrony—defined as the extent to which family members’ affective states change together—was modeled at both overall (between-family) and momentary (within-family) levels. Results indicated that families exhibited greater synchrony in positive affect than negative affect, alongside substantial heterogeneity in network structures. At the person level, greater positive affect synchrony was associated with higher adolescent well-being and lower distress, whereas negative affect synchrony showed inverse patterns. At the momentary level, increases in negative affect synchrony were associated with higher concurrent well-being and lower stress. Many of these person-level associations were substantially attenuated once adolescents’ general affect levels were accounted for, whereas synchrony at the between-family level continued to predict adolescents’ momentary well-being beyond their concurrent affect. These findings highlight emotional synchrony as a dynamic property of family systems and underscore the importance of modeling family processes across multiple timescales.
