Background and Purpose: Despite administration of evidence-based therapies, residual risk of stroke recurrence persists. This study aimed to evaluate the residual risk of recurrent stroke in acute ischemic stroke or transient ischemic attack (TIA) with adherence to guideline-based secondary stroke prevention and identify the risk factors of the residual risk. Methods: Patients with acute ischemic stroke or TIA within 7 hours were enrolled from 169 hospitals in Third China National Stroke Registry (CNSR-III) in China. Adherence to guideline-based secondary stroke prevention was defined as persistently receiving all of the five secondary prevention medications (antithrombotic, antidiabetic and antihypertensive agents, statin and anticoagulants) during hospitalization, at discharge, at 3, 6, and 12 months if eligible. The primary outcome was a new stroke at 12 months. Results: Among 9,022 included patients (median age 63.0 years and 31.7% female), 3,146 (34.9%) were identified as adherence to guideline-based secondary prevention. Of all, 864 (9.6%) patients had recurrent stroke at 12 months, and the residual risk in patients with adherence to guidelinebased secondary prevention was 8.3%. Compared with those without adherence, patients with adherence to guideline-based secondary prevention had lower rate of recurrent stroke (hazard ratio, 0.85; 95% confidence interval, 0.74 to 0.99; P=0.04) at 12 months. Female, history of stroke, interleukin- 6 ≥5.63 ng/L, and relevant intracranial artery stenosis were independent risk factors of the residual risk. Conclusions: There was still a substantial residual risk of 12-month recurrent stroke even in patients with persistent adherence to guideline-based secondary stroke prevention. Future research should focus on efforts to reduce the residual risk.

A novel Mn-Ce-Nb-Ox/P84 catalyticfilter for synergetic removal of particulates and NO was designed andprepared by a new method using functional foaming coating. Removal characteristics of nitrogen oxides(including catalyst loading amount, O2 concentration, NH3/NO molar ratio, H2O and SO2) andparticulates, were systematically studied. Results showed that the NO removal efficiency of catalyticfilter reached 95.3% at 200 C, as the catalyst loading amount,filtration velocity and mole ratio of NH3/NOwere set to be 450 g/m2, 1 m/min and 1, respectively. The removal characteristic of particulates of Mn-Ce-Nb-Ox/P84 catalyticfilter belonged surfacefiltration and the PM2.5 removal efficiency reached 99.98%.

Zhiwei Xue,Shemin Zhu,Yuesong Shen,Shubao Shen,Chengliang Li 한국공업화학회 2015 Journal of Industrial and Engineering Chemistry Vol.30 No.-

Promotional effects of Ce4+, La3+ and Nd3+ incorporations on FeCu2O3.5/ATS for decomposing N2O wereinvestigated. Results showed that all the ions especially La3+ can dramatically improve the catalyticperformance. FeCu2La1.5Ox/ATS, the optimal catalyst, can decompose 100% N2O at 550 8C. The formedperovskite-type LaFeO3 and spinel-type CuLa2O4 largely improved catalytic performance. The ionmodification increased N2O adsorption capacity, and La3+-doped catalyst enhanced desorption ability ofsurface oxygen. Both effects can accelerate the rate-determine steps of N2O decomposition reaction,promote catalytic performance. Moreover, the supported catalysts studied were economic efficiency forapplication.

Influencing factors on low-temperature deNOx performance of Mn–La–Ce–Ni–Ox/PPS catalytic filters applied for cement kiln

She-Min Zhu,Da-Hai Zheng,Yuesong Shen,Yun-Shun Qiu,Bing Li,Yan-Wei Zeng,Shubao Shen,Shemin Zhu 한국공업화학회 2015 Journal of Industrial and Engineering Chemistry Vol.24 No.-

Effects of catalyst loading amount, reaction temperature, O2 concentration, NH3/NO molar ratio and SO2 on low-temperature catalytic performance of the Mn–La–Ce–Ni–Ox (Mn/La/Ce/Ni = 2.5:2.5:1:1 in mol)/ PPS for NH3-SCR of NO were mainly studied. Results showed that the filter with catalyst loading amount of 250 g/m2 obtained more than 95% NO removal efficiency at 200 8C under filtration velocity of 1 m/min. The NO removal efficiency was still above 85% by injecting 300 ppm SO2 at 200 8C. Anyway, the Mn–La– Ce–Ni–Ox/PPS catalytic filter is promising to achieve the expectation of simultaneous removing particulate and NOx from low-sulfur flue gas in cement kiln.

EpiLoc: Deep Camera Localization Under Epipolar Constraint

Luoyuan Xu,Tao Guan,Yawei Luo,Yuesong Wang,Zhuo Chen,WenKai Liu 한국인터넷정보학회 2022 KSII Transactions on Internet and Information Syst Vol.16 No.6

Recent works have shown that the geometric constraint can be harnessed to boost the performance of CNN-based camera localization. However, the existing strategies are limited to imposing image-level constraint between pose pairs, which is weak and coarse-gained. In this paper, we introduce a pixel-level epipolar geometry constraint to vanilla localization framework without the ground-truth 3D information. Dubbed EpiLoc, our method establishes the geometric relationship between pixels in different images by utilizing the epipolar geometry thus forcing the network to regress more accurate poses. We also propose a variant called EpiSingle to cope with non-sequential training images, which can construct the epipolar geometry constraint based on a single image in a self-supervised manner. Extensive experiments on the public indoor 7Scenes and outdoor RobotCar datasets show that the proposed pixel-level constraint is valuable, and helps our EpiLoc achieve state-of-the-art results in the end-to-end camera localization task.

Postthrombolytic Antiplatelet Use for Patients with Intercerebral Hemorrhage without Extensive Parenchymal Involvement Does Not Worsen Outcome

Background and Purpose It is unclear whether postthrombolytic antiplatelet (AP) therapy after thrombolytic-related hemorrhage without extensive parenchymal involvement (THEPI) afects the clinical outcome. Tis study explored whether AP administration in patients with THEPI afects short- and long-term outcomes. Methods All of the data for this study were collected from the Trombolysis Implementation and Monitor of Acute Ischemic Stroke in China (TIMS-China) registry. Patients with THEPI were assigned to either the AP (AP therapy should be commenced 24 h afer intravenous thrombolysis) or AP-naïve groups. THEPI was defned according to European-Australasian Acute Stroke Study II criteria. Te 90-day functional outcome, 7-day National Institutes of Health Stroke Scale (NIHSS) score, and 7-day and 90-day mortalities were compared between the AP and AP-naïve groups. Logistic regression analysis was used to evaluate the effects of AP therapy on the short- and long-term clinical outcomes. Results Of the 928 patients enrolled from those in the TIMS-China registry (n=1,440), 89 (9.6%) had nonsymptomatic intracerebral hemorrhage (ICH) within 24–36 h afer thrombolysis; 33 (37%) of these patients were given AP therapy (AP group) and 56 (63%) were not (APnaïve group). No significant differences were found for the risk of 7-day aggravated ICH (p=0.998), 7-day NIHSS score (p=0.5491), 7-day mortality [odds ratio (OR)=3.427; 95% confdence interval (95% CI)=0.344–34.160; p=0.294], 90-day mortality (OR=0.788, 95% CI=0.154– 4.040, p=0.775), or modifed Rankin score 5 or 6 at 90-days (OR=1.108, 95% CI=0.249–4.928, p=0.893) between the AP and AP-naïve groups afer THEPI. Conclusions Early administration of postthrombolytic AP therapy afer THEPI does not worsen either the short- or long-term outcome. AP therapy may be a reasonable treatment option for patients with THEPI to reduce the risk of ischemic stroke recurrence.

Series of CeSn0.8W0.6Ox/TiO2 catalysts were tested for selective catalytic reduction of NO and forsynergistic catalytic removals of CO and C3H8 from diesel engine exhaust. Results revealed that catalyst12%-CeSn0.8W0.6Ox/TiO2 calcined at 500 C exhibited the optimal catalytic performance for NH3-SCR ofNO. The catalyst obtained more than 90% NO conversion at a wide temperature range of 252–456 C. BothCO and C3H8 could be oxidized into CO2 by the optimized catalyst. Moreover, excellent redox property,rich surface acidity and big specific surface area were the promotional factors for good catalyticperformance in catalytic removals of NO, CO and C3H8.
