IO Die can be used as an IO extension chip, or a chiplet, which can be reused for multiple projects. This paper proposes an agile verification method of an IO Die. In order to reuse cross-level test cases, three levels (sub-system level, cluster level and whole chip level) are realized on the verification platform, and test cases at each verification level are optimized. Coverage drive, configurable constraint generation and multi-objective optimization methods are adopted respectively to improve the generation efficiency of test cases. Experimental results show that, this method can reduce the cost and time and effectively achieve Known Good Die (KGD) on the premise of ensuring efficiency and reliability. [ABSTRACT FROM AUTHOR]

Direct connection of multi-core processors to build multi-way parallel systems has always been the main way to improve the parallelism of high-performance computers. This paper mainly studies the QoS design and verification of the multi-core processor's direct connection interface. Through the direct connection interface, the cache consistent message across the chip can be effectively and reliably transmitted, and the SMP system (symmetric multiprocessing) sharing main memory can be realized. In this paper, the key technologies of QoS design for each protocol layer of direct connection interface are described in detail. After the validity of QoS design is verified by the reusable verification platform based on UVM method, it has been transplanted to the FPGA prototype verification platform and passed the test successfully. In order to improve the performance of multi-way servers, it is necessary to further study the direct connection technology of multi-core processors, which has good application and research prospects.

Objective：The aim of this article is to determine the feasibility and safety of intraoperative cell salvage (IOCS) technology in obstetric hemorrhage during cesarean section. Methods：Data of intraoperative blood salvage in the Army Medical University affiliated Xinqiao Hospital from January 2013 to December 2017 were analyzed. A total of 571 patients were included in this study, who were diagnosed for placenta previa and underwent cesarean section. 264 women who signed informed consent for accepting IOCS and received re -infusion were included in the observation group, 307 women signed informed consent allogeneic transfusion when necessary were included in the control group. Baseline demographic data, laboratory and perioperative findings, transfusion adverse effects were analyzed. Results：In the observation group, blood loss was more than that in the control group (Z=-6.993, P=0.000). The proportion of cases with total blood transfusion ≥2 000 mL, transfusion of plasma, cryoprecipitate, and platelet were more than those in the control group, but the amount of erythrocyte transfusion was less than those in the control group (P＜0.05). However, there were no significant differences regarding of the days of postoperative ICU the preoperative and postoperative Hb, HCT, PLT levels (P＞0.05). Postoperative complications within 24 hours were no significant differences between the two groups (P＞0.05). Conclusions：The strategy of intraoperative cell salvage was feasible and safe for women with placenta previa undergoing cesarean section. [ABSTRACT FROM AUTHOR]

BACKGROUND: The surface electromyography can evaluate the effect of exercise by recording the parameters of muscle activities, and vibration exercise is the best supplement to traditional weight training. More research focuses on the effect of simple vibration training on the surface electromyography of lower limbs, but the influence of vibration combined with weight-bearing training is poorly understood. OBJECTIVE: To study the effect of vibration combined with load on the surface electromyography of lower limbs at the micro level of muscle working principle. METHODS: Eight healthy college students were recruited, and subjected to four different stimulations: vibration (45 Hz) combined with load (45% one repetition maximum (IRM)); vibration (45 Hz) combined with load (60% 1RM); vibration (50 Hz) combined with load (45% 1RM); vibration (50 Hz) combined with load (60% 1RM), followed by semi-squat exercise with the heel lifting, 10 times/minute, for 3 courses with more than 2 hours in between. RESULTS AND CONCLUSION: Different vibrations combined with loads made significant difference on the root mean square amplitude of the surface electromyography (P < 0.01), and there was a significantly increased root mean square amplitude in the vibration (50 Hz) combined with load (45% 1RM), especially at the medial gastrocnemius. The four kinds of stimulations made significant different effects on the surface electromyography of rectus femoris, tibialis anterior, and medial gastrocnemius, except semitendinosus (P ≤ 0.05). Moreover, the effect showed significant difference among different stimulations except vibration (50 Hz) combined with load (45% 1RM) (P ≤ 0.05). Compared with the other three stimulations, vibration (50 Hz) combined with load (45% 1RM) exerted better effect on the muscular activation. To conclude, different vibrations combined with loads exert different effects on the motor unit of same neuromuscular activity, and a suitable stimulation may produce better effect. Besides, the same stimulus for the motor unit of different neuromuscular activities produces different effects, which may match to the muscle nature. [ABSTRACT FROM AUTHOR]

As the complexity of integrated circuit design increases exponentially, functional verification has become a bottleneck in large-scale chip design. And in multi-core processor design, Cache coherency protocols are very complex and difficult to verify. We propose a random test generation method based on Bayesian network for simulation-based verification to solve the state space explosion problem of Cache coherency protocols. We discuss the Cache coherency protocol, analyze the coverage directed test generation (CDG) method based on Bayesian network reasoning, and apply the method to Cache consistency verification. Taking the verification of the Cache coherence protocol of the FT processor as an example, the results show that the CDG method can increase coverage by nearly 30% in comparison with the pseudo-random test.

Objective To investigate the value of three-dimensional speckle tracking imaging (3D-STI) in evaluating the right ventricular (RV) function of uremia patients undergoing peritoneal dialysis (PD). Methods Thirty-five uremia patients undergoing PD (PD group) and 26 healthy subjects (control group) were enrolled. Left ventricular end-diastolic inner diameter (LVIDd), left ventricular end-systolic inner diameter (LVISd), interventricular septum thickness (IVSd), left ventricular ejection fraction (LVEF), right ventricular diastolic inner diameter of the base (basal RVd), right ventricular fractional area change (RVFAC) and pulmonary artery systolic pressure (PASP) were recorded by conventional ultrasound in the PD group and the control group before dialysis and 3-6 months after dialysis. The right ventricular global longitudinal peak systolic strain (RVGLS), right ventricular global circumferential peak systolic strain (RVGCS), right ventricular global radial peak systolic strain (RVGRS), right ventricular global area peak systolic strain (RVGAS), right ventricular end systolic volume (RVESV), right ventricular end diastolic volume (RVEDV) and right ventricular ejection fraction (RVEF) were measured by 3D-STI. Results Conventional ultrasound measurements: compared with the control group, LVIDd, LVISd, IVSd and PASP increased in the PD group before dialysis (P<0. 05 or P<0. 01); LVEF and the volume of right ventricle had no significant changes (all P>0. 05); the above indexes of the PD group had no significant differences before and after dialysis (all P>0. 05). Three-dimensional speckle tracking calculation results: compared with the control group, the absolute values of RVGLS, RVGAS, RVGCS and RVGRS decreased significantly before dialysis (all P<0. 05), RVEDV and RVESV increased in the PD group (all P<0. 05), and we did not observed any significant difference in RVEF (P>0. 05). In the PD group, RVEDV and RVESV decreased significantly (all P<0. 05), and the absolute value of RVGLS increased significantly as compared with those before dialysis (P<0. 05). Conclusions The application of 3D-STI can facilitate the early detection of decreased GLS, GRS, GCS, GAS and the increased EDV and ESV of the right ventricle in uremic patients when RVEF was normal. RVGLS can be used as an important parameter for right ventricular function improvement in uremic patients undergoing PD. [ABSTRACT FROM AUTHOR]

Objective To investigate the effect of uterine natural killer (uNK) cells in the endometrium of implantation window stage on endometrial angiogenesis and the relationship between uterine artery pulsation index and in vitro fertilization (IVF) treatment outcome. Methods We recruited 30 patients who all had received IVF and embryo transfer (IVF-ET) at the age of less than 35 years. Uterine artery pulsation indexes were assessed by vaginal color Doppler, and the endometrium in the window of implantation was collected. Expression and localization of CD56+, uNK cells marker; F8 factor, vascular endothelial cell marker; alpha smooth muscle actin (αSMA), vascular smooth muscle cell marker; and heavy chain smooth myosin (SMM) were detected by immunohistochemical SP method. The patients were divided into pregnancy group and repeated implantation failure group based on assisted pregnancy outcome. Results ① The positive expression rates of uNK cells and F8 factor were positively related (r=0.581, P<0.01). ② The positive expression rate of uNK cells was positively related to that of αSMA and SMM (r=0.572, r=0.569, P<0.01). ③ Uterine artery pulsation index was 0.85±1.51 in repeated implantation failure group and 0.93±0.24 in pregnancy group, without any significant difference between the two groups (t=-0.98, P>0.05). Conclusion ① uNK cells in the window of implantation are positively correlated with microvascular density and vascular maturity, indicating that they play an important role in angiogenesis of the endometrium. ② The effect of uterine artery dynamic index on embryo transfer outcome does not differ significantly between pregnancy group and repeated implantation failure group. Further study is needed. [ABSTRACT FROM AUTHOR]
