14. Optimization of Capacitive Six-Axis Force/Torque Sensors Based on Error Analytical Model

Author

Pu, Minghui, Wang, Yaozong, Zhao, Rendong, Tian, Longxiang, Lu, Yuhai, Yang, Yukun, and Luo, Chengxuan

Abstract

The measurement accuracy of capacitive six-axis force/torque (F/T) sensors is difficult to predict and determine during the design process, which leads to the uncertainty of the actual measurement accuracy of the sensor. In this article, a sensor accuracy prediction method based on an error analysis model is proposed. A mathematical model for mapping the six-axis F/T to changes in capacitance is established by computing the overall flexibility matrix of the elastic structure. The influence mechanism of various errors on the measurement accuracy of the six-axis F/T sensor system is deeply analyzed, and a mathematical model for error prediction and a comprehensive performance evaluation index function is established. The comprehensive performance evaluation index function is proposed, coupled with applying a nonlinear programming genetic algorithm for parameter optimization. A prototype was fabricated using the optimization results and calibration experiments were conducted to verify its accuracy. The experimental results demonstrate that the nonlinearity error of the prototype is 0.280% full scale (FS), and the calibration measurement accuracy is 0.601%FS. The design method proposed in this article effectively enables the development of high-precision capacitive six-axis F/T sensors.

In this study, we developed a tissue-engineered mesh (TEM) by seeding autologous bone marrow-derived mesenchymal stem cells onto nanosized fibers decellularized aorta (DA). DA was achieved by decellularizing the aorta sample sequentially with physical, mechanical, biological enzymatic digestion, and chemical detergent processes. The tertiary structure of DA was constituted with micro-, submicro-, and nanosized fibers, and the original strength of fresh aorta was retained. Inguinal hernia rabbit models were treated with TEMs or acellular meshes (AMs). After implantation, TEM-treated rabbit models showed no hernia recurrence, whereas AM-treated animals displayed bulges in inguinal area. At harvest, TEMs were thicker, have less adhesion, and have stronger mechanical strength compared to AMs (P<0.05). Moreover, TEM showed better cell infiltration, tissue regeneration, and neovascularization (P<0.05). Therefore, these cell-seeded DAs with nanosized fibers have potential for use in inguinal hernioplasty.

Abstract

Background Adefovir dipivoxil (ADV) is a nucleotide analogue with proven efficacy in chronic hepatitis B (CHB). Aims This study investigated long-term ADV treatment in HBeAg-positive patients. Methods A total of 480 Chinese subjects with HBeAg-positive CHB who participated in a 1-year, double-blind, placebo-controlled study of ADV 10 mg daily were offered open-label continuation for a further 208 weeks. Results A total of 390 subjects completed 5 years of treatment. Baseline median hepatitis B virus (HBV) DNA was 8.8 log10 copies/ml and alanine aminotransferase (ALT) 2.6 × upper limit of normal. Treatment with ADV resulted in sustained suppression of median HBV DNA by 4.8, 5.0, 5.1, 5.4 and 5.5 log10 copies/ml after 1, 2, 3, 4 and 5 years respectively. Continuous treatment with ADV led to a progressive increase in the proportion of subjects achieving undetectable HBV DNA, from 28% after 1 year to 58% after 5 years. HBeAg seroconversion rates increased cumulatively from 11% after 1 year to 29% after 5 years. HBsAg seroconversion was achieved by 1.0% of patients. ADV resulted in ALT normalization that was maintained throughout this study in 75–79% of subjects. Virological breakthrough associated with ADV resistant mutations (rtN236T and rtA181V) occurred in 14.6% of subjects. ADV was well tolerated. Conclusion Five years of ADV treatment in Chinese subjects with HBeAg-positive CHB resulted in increasing virological and serological responses and sustained biochemical responses over time. Virological resistance was identified in 14.6% of patients. Urgent switch or add-on therapy with a nucleoside analogue is necessary if ADV resistant mutations are detected, particularly rtN236T. Treatment was well tolerated.

Abstract

Objective: To investigate the effectiveness of minimally invasive plate and medial supporting cannulated screw fixation via tarsal sinus approach in treatment of Sanders type Ⅱ and Ⅲ calcaneal fractures., Methods: A clinical data of 46 patients with Sanders type Ⅱand Ⅲ calcaneal fractures met the selective criteria between March 2016 and March 2021 was retrospectively analyzed. The factures were fixed with minimally invasive plate and medial supporting cannulated screws via tarsal sinus approach in 20 cases (group A) and with minimally invasive plate in 26 cases (group B). There was no significant difference between groups in term of the gender, age, injury causes, fracture type and side, the time from injury to operation, and preoperative calcaneal length and width, Böhler angle, Gissane angle, and visual analogue scale (VAS) score ( P >0.05). The operation time, intraoperative blood loss, hospital stay, and the interval between operation and full weight-bearing were recorded. The pain improvement of patients was evaluated by VAS scores before operation and at 48 hours after operation. The ankle joint function was evaluated by American Orthopaedic Foot and Ankle Society (AOFAS) score at 3 and 12 months after operation. Besides, the calcaneal length and width, Böhler angle, and Gissane angle were measured by X-ray films before and after operation. Furthermore, the difference (loss value) between 3, 12 months and 1 day after operation was calculated. Moreover, the fracture healing and healing time was observed., Results: All operations of two groups were successfully completed. The incisions healed by first intention, and no vascular/nerve injury or incision infection occurred. The operation time of group A was significantly longer than that of group B ( P <0.05). There was no significant difference in the intraoperative blood loss, hospital stay, and the interval between operation and full weight-bearing ( P >0.05). All patients were followed up 12-36 months (mean, 14.8 months). The VAS scores at 48 hours after operation were significantly lower than those before operation in the two groups ( P <0.05); there was no significant difference in the difference of pre- and post-operative VAS score between groups ( P >0.05). The AOFAS scores at 12 months after operation were significantly higher than those at 3 months after operation in the two groups ( P <0.05); and there was no significant difference between groups at 3 and 12 months ( P >0.05). X-ray films showed that the fractures of the two groups healed and there was no significant difference in healing time ( P >0.05). There was no significant difference in calcaneal length and width and Gissane angle between groups at each time point ( P >0.05), but there was significant difference in Böhler angle between groups at 12 months ( P <0.05). The imaging indexes of the two groups significantly improved at each time point after operation when compared with those before operation ( P <0.05). There was no significant difference between different time points after operation ( P >0.05) in the imaging indexes of group A. There were significant differences in the calcaneal length, calcaneal width, and Gissane angle of group B between 12 months and 1 day, 3 months after operation ( P <0.05), and there was no significant difference between 1 day and 3 months after operation ( P >0.05). The differences in Böhler angle of group B between different time points after operation were significant ( P <0.05). There was no significant difference between groups in the loss of all imaging indexes at 3 months after operation ( P >0.05). The losses of calcaneal width, Böhler angle, and Gissane angle in group A at 12 months after operation were significantly smaller than those in group B ( P <0.05), and there was no significant difference in the loss of calcaneus length between groups ( P >0.05)., Conclusion: Compared with only minimally invasive plate fixation, the combination of minimally invasive plate and medial supporting cannulated screw fixation via tarsal sinus approach for Sanders type Ⅱ and Ⅲ calcaneal fractures has the advantages of less trauma, less incision complications, reliable fracture reduction and fixation, and good long-term stability.

Abstract

Objective: The purpose of this study was to compare the diagnostic capabilities of magnetic resonance imaging (MRI) and ultrasonography (US) for cervical lymph nodal metastases in differentiated thyroid carcinoma (DTC) before reoperation., Material and Method: From June 2011 to May 2013, preoperative MRI and ultrasound data were collected from differentiated thyroid cancer patients who underwent a reoperation. The following characteristics were assessed: the sensitivity, specificity, positive predictive value, negative predictive value and accuracy of MRI and US. The MRI and ultrasound findings were correlated with the histological diagnosis after reoperation., Results: One hundred and thirty-eight cases were included in the analysis. 88.4% (122/138) of which had evidence of residual thyroid cancer tissue or metastatic nodal involvement at final histology. Lymph nodal metastases were confirmed in the central compartment in 76.42% (81/106) of patients and in lateral compartment in 73.28% (85/116) of patients. The sensitivity, specificity and accuracy of MRI VS US for detecting central compartment metastases was 75% VS 41.67% (P=0.04), 90.91% VS 100% (P=1) and 80% VS 60% (P=0.618), respectively; For detecting lateral compartment metastases was 83.33% VS 77.78% (P=1), 25% VS 50% (P=0.606) and 65.38% VS 69.23% (P=1), respectively. There was statistically significant difference between the sensitivity of MRI and ultrasound for diagnose of central compartment metastases. The MRI features with the greatest correlation with positive lymph nodal metastases were fusion and enhancing lesions. The ultrasound features with the greatest correlation with positive lymph nodal metastases were hypoechoic and microcalcifications., Conclusion: MRI is more sensitive than ultrasonography in detecting central compartment metastases in papillary thyroid carcinoma. There is no significant difference in diagnosis of lateral neck node metastases between MRI and US.
