The increase of IC design complexity and the continuous reduction of process feature size bring new severe challenges to static timing analysis (STA) and chip design cycle. In order to improve the efficiency of STA and shorten the chip design cycle, this paper fully considers the FinFET process characteristics and the principle of STA, and predicts the timing characteristics of another part of corners by introducing machine learning methods based on the timing characteristics of some corners. The experiment is based on an industrial design, and the results show that the proposed method uses 5 corners to predict the timing of other 31 corners, which can achieve an average absolute error of less than 2 ps, far better than the 21 process angles required by traditional methods. Thus, the proposed method significantly improves the prediction accuracy and significantly reduces the workload of static time series analysis. [ABSTRACT FROM AUTHOR]

Objective To evaluate the efficacy and safety of venous sinus stenting (VSS) for the treatment of refractory pseudotumor cerebri syndrome in Chinese people. Methods This is a retrospective single-center cohort study. Patients with medically refractory PTCS who underwent VSS from March 2019 to June 2022 at the neuro-ophthalmology division in the Eye & ENT Hospital of Fudan University were enrolled. Demographic data and neuro-ophthalmological clinical characteristics including visual outcomes, papilledema and optical coherence tomography (OCT) were collected. Results Eleven patients (22 eyes) were assessed in this study (4 males and 7 females; mean age: 50.00±11.88 with range of 28 –73 years; mean BMI: 24.67±2.36 with range of 21.8–28.0 kg/m². Ten patients presented with transient visual obscuration and tinnitus, whereas three had headaches. After surgery, the degree of papilledema and visual function were improved dramatically in eight patients, and the degree of optic atrophy and visual function were stabilized in three patients with advanced optic atrophy. The thickness of peripapillary retinal nerve fiber layer (RNFL) decreased after surgery, whereas the macular ganglion cell inner plexiform layer complex (GCIPL) kept stabilized. There were no severe complications after VSS surgery. Conclusions VSS was effective and safe for the treatment of medically refractory PTCS, especially during early stages the disease. Optical coherence tomography measurement of the GCIPL was useful for predicting the prognosis of refractory PTCS after surgery. [ABSTRACT FROM AUTHOR]

Objective To analyze risk factors for the poor prognosis of severe aortic stenosis (AS), and to evaluate the influence of blood pressure and blood pressure fluctuation on the poor prognosis of severe AS. Methods Clinical data of patients with acute decompensation of chronic heart failure (CHF) admitted to the Cardiac Intensive Care Unit of Tianjin Chest Hospital from December 2018 to March 2022 were collected. Patients were divided into the AS group and the non- NAS group according to aortic stenosis lesions. Baseline clinical data, follow-up results, blood pressure for consecutive 3 days after admission and blood pressure monitoring values for 2 days before discharge were collected, and indexes such as mean arterial pressure (MAP), systolic pressure difference (ΔSBP) and diastolic pressure difference (ΔDBP) were calculated. The primary endpoint event was a composite endpoint of rehospitalization and/or all-cause death due to heart failure, and the secondary endpoint event was cardiogenic death. The Kaplan-Meier survival curve was used to compare the survival differences between the two groups. Univariate and multivariate Cox regression models were used to analyze prognostic factors of aortic stenosis in patients with AS. Further subgroup analysis was conducted according to whether the AS group was complicated with hypertension and the ΔSBP quartile to compare the occurrence of end events and outcome differences between groups. Results Ninety-one patients were included, including 50 in the AS group and 41 in the NAS group. Compared with the NAS group, the AS group was older, and had a higher proportion of smoking history, diabetes history, and lower extremity edema symptoms on admission, lower albumin level, and higher pulmonary artery systolic blood pressure (P＜0.05). Kaplan-Meier results showed that the incidence of primary (P=0.030) and secondary (P=0.037) endpoint events were higher in the AS group than that in the NAS group. Cox regression results showed that old age, combined hypertension, elevated ΔSBP, and elevated NE were independent risk factors for primary endpoint events (P＜0.05), and old age and elevation of ΔSBP and ΔDBP were independent risk factors for secondary endpoint events (P＜0.05). Subgroup analysis showed that the incidence of primary endpoint events was higher in AS patients with hypertension than that in AS patients with non-hypertension patients (P=0.011). The larger the ΔSBP, the higher the incidence of primary endpoint events in the AS group (P＜0.001). Conclusion Hypertension, elevated Δ SBP and old age are independent risk factors for poor prognosis of AS. Patients with AS have lower survival rates. The greater the fluctuation of blood pressure, the lower the survival rate and the worse the prognosis of AS patients. [ABSTRACT FROM AUTHOR]

Objective To establish, analyze, and screen ideal models based on machine learning algorithms to predict the positive rate of patients who received repeated prostate punctures for guiding clinical decision-making. Methods Clinical data of 281 male patients from multiple centers who underwent at least two consecutive prostate biopsies from January 2008 to December 2022, were retrospectively analyzed, and their first biopsy pathology result was recorded as negative. Key clinical diagnosis and treatment data were recorded for each patient, including BMI, prostate volume, PSA level, fPSA/PSA ratio, PSAD level, complications after the first puncture, pathological results after the first puncture, and strategies used for the two prostate punctures. Statistical analysis was used to analyze the differences in parameters between the final puncture pathology positive group and the negative group. The parameters were trained and fitted through seven machine learning algorithm models such as multivariable logical regression (LR), K-nearest neighbor search (KNN), support vector machine (SVC), decision tree (DT), random forest classifier (RF), naive Bayes classifier (NBC) and gradient enhancement tree (GB). 70% of all data as training set data and 30% of the remaining as verification set data were used for six times cross validation to analyze and compare accuracy and sensitivity, the diagnostic accuracy of each model was evaluated using receiver operating characteristic curve, and its effectiveness in predicting the results of prostate cancer secondary puncture was ultimately evaluated. Results The patients were aged between 32 and 87 years old, with an average of 69. 03 years old. Among the patients, 201 patients were recorded as negative in the final puncture pathology, and 80 patients were recorded as prostate cancer. The inter-group analysis showed that there were significant statistical differences (P <0. 05) in the age of second puncture, volume of first puncture prostate, volume of second puncture prostate, PSA level of second puncture, PSAD of second puncture, and FPSA/PSA ratio of second puncture. All collected data were randomly divided into two parts, such as the training dataset (197 cases, 70% of prostate puncture patients) and the validation dataset (84 cases, the remaining 30%). The results showed that the accuracy rates of LR, KNN, SVC, DT, GNB, RF, and GB in predicting the results of secondary prostate puncture were found to fluctuate between 66. 67% and 74. 88%, the error rates to fluctuate between 21.43% and 34. 29%, the recall rates to fluctuate between 9. 52% and 47. 62%, the specificity to fluctuate between 79. 59 and 97. 96%, the accuracy to fluctuate between 33. 33% and 80. 00%. The specificities of each model (the area under the ROC curve) were found to fluctuate between 0. 568 and 0. 725. Conclusion SVC can more accurately predict the positivity of secondary prostate puncture with fewer parameters. Compared to other algorithm models, it makes the prediction results to have better sensitivity and specificity. Through the collection and training of larger sample size data, it has the potential to become a detection tool with broad compatibility for predicting prostate secondary puncture results.
