a b s t r a c tIn this paper, some properties of the generalized f -projection operator are proved in Banach spaces. Using these results, the strong convergence theorems for relatively nonexpansive mappings are studied in Banach spaces. As applications, the strong convergence of general H-monotone mappings in Banach spaces is also given. The results presented in this paper generalize and improve the main results of Matsushita and Takahashi (2005) [9].

Background: Readmission after acute myocardial infarction in low- and middle-income countries like China is not well characterized. Methods and Results: We approached consecutive patients with acute myocardial infarction hospitalized within 24 hours of symptom onset and discharged alive from 53 geographically diverse hospitals in China. We described rates of unplanned 30-day readmission, their timing and admitting diagnoses, and fit Cox proportional hazards models to identify factors associated with readmission. Among 3387 patients, median (interquartile range) age was 61 (52–69) years, and 76.9% were men. The index median length of stay was 11 (8–14) days. Unplanned 30-day readmission occurred in 6.3% of the cohort; most readmissions (77.7%) were for cardiovascular diagnoses. Nearly half (41.9% of all-cause readmissions; 44.3% of cardiovascular readmissions) occurred within 5 days of discharge. Mini-Global Registry of Acute Coronary Events scores at admission (hazard ratio [HR], 1.15 for every 10-point increase; 95% CI, 1.05–1.25), longer length of stay (HR, 1.03; 95% CI, 1.00–1.06 for each extra day), and in-hospital recurrent angina (HR, 1.40; 95% CI, 1.04–1.89) were associated with higher unplanned all-cause readmission. Revascularization during the index hospitalization (70.2% of the cohort) was associated with lower risks of all-cause readmission (HR, 0.27; 95% CI, 0.18–0.42). In addition, left ventricular ejection fraction <0.4 (HR, 1.79; 95% CI, 1.05–3.07) and in-hospital complication (HR, 1.20; 95% CI, 1.03–1.39) were associated with higher risk of unplanned cardiovascular readmission, and ST-segment–elevation myocardial infarction (HR, 0.60; 95% CI, 0.36–0.98) was associated with lower risk of unplanned cardiovascular readmission. Sex, family income, depression, stress level, lower social support, disease-specific health status, and medications were not associated with readmission. Conclusions: In China, most readmissions are for cardiovascular events, and almost half occur within 5 days of discharge. Clinical factors identify patients at higher and lower unplanned readmissions. Clinical Trial Registration: URL: https://www.clinicaltrials.gov . Unique identifier: NCT01624909.

To compare the newly determined sequences against the subject sequences stored in the databases is a critical job in the bioinformatics. Fortunately, recent survey reports that the state-of-the-art aligners are already fast enough to handle the ultra amount of short sequence reads in the reasonable time. However, for aligning the long sequence reads (>400 bp) generated by the next generation sequencing (NGS) technology, it is still quite inefficient with present aligners. Furthermore, the challenge becomes more and more serious as the lengths and the amounts of the sequence reads are both keeping increasing with the improvement of the sequencing technology. Thus, it is extremely urgent for the researchers to enhance the performance of the long read alignment. In this paper, we propose a novel FPGA-based system to improve the efficiency of the long read mapping. Compared to the state-of-the-art long read aligner BWA-SW, our accelerating platform could achieve a high performance with almost the same sensitivity. Experiments demonstrate that, for reads with lengths ranging from 512 up to 4,096 base pairs, the described system obtains a 10x -48x speedup for the bottleneck of the software. As to the whole mapping procedure, the FPGA-based platform could achieve a 1.8x -3:3x speedup versus the BWA-SW aligner, reducing the alignment cycles from weeks to days.
