Abstract

The hopping pattern for D2D Discovery are investi- gated. We propose three metrics for hopping pattern performance evaluation: column period, maximal collision ratio, maximal con- tinual collision number. A class of hopping patterns is constructed based on the metrics, and through simulation the patterns show better discovery performance.

Abstract

The treadmill exercise test (TET) serves as a non-invasive method for the diagnosis of coronary artery disease (CAD). Despite its widespread use, TET reports are susceptible to external influences, heightening the risk of misdiagnosis and underdiagnosis. In this paper, we propose a novel automatic CAD diagnosis approach. The proposed approach introduces a customized preprocessing method to obtain clear electrocardiograms (ECGs) from individual TET reports. Additionally, it presents TETDiaNet, a novel neural network designed to explore the temporal relationships within TET ECGs. Central to TETDiaNet is the TETDia block, which mimics clinicians' diagnostic processes to extract essential diagnostic information. This block encompasses an intra-state contextual learning module and an inter-state contextual learning module, modeling the temporal relationships within a single state and between states, respectively. These two modules help the TETDia block to capture effective diagnosis information by exploring the temporal relationships within TET ECGs. Furthermore, we establish a new TET dataset named TET4CAD for CAD diagnosis. It contains simplified TET reports for 192 CAD patients and 224 non-CAD patients, and each patient undergoes coronary angiography for labeling. Experimental results on TET4CAD underscore the superior performance of the proposed approach, highlighting the discriminative value of the temporal relationships within TET ECGs for CAD diagnosis.

Abstract

To solve the problem of transition of the tower crane with high center of gravity,through sex difference,fixed transportation for the tower body and its attached parts being put down may be regarded as a fast and efficient method. Four-bar linkage was adopted to put down the towerbody,its working principle is introduced,then the force analysis of its components is carried,finally,its simulation and optimization is carried out through using MATLAB. The feasibility and practicability of the method are verified by numerical examples and engineering practice.

Abstract

Aims: Renal anaemia is a common complication of chronic kidney disease (CKD). Roxadustat is the first‐in‐class oral hypoxia‐inducible factor prolyl hydroxylase inhibitor for the treatment of anaemia. In this systematic review, we aimed to investigate the efficacy and safety of roxadustat in the treatment of anaemia in CKD patients. Methods: PubMed, Cochrane Library, Embase, and ClinicalTrials.gov databases were searched from their inception to February 2021 for randomised controlled trials (RCTs) that compared the efficacy and safety of roxadustat to those of an erythropoiesis‐stimulating agent (ESA) or a placebo in treating anaemia in CKD patients. Results: Nine RCTs involving 2743 patients were found. The meta‐analysis showed that roxadustat increased haemoglobin (Hb) level by 0.91 g/dL (95% confidence interval [CI]: 0.47–1.34, P <.05), transferrin level by 0.50 mg/dL (95% CI: 0.34–0.65, P <.05), and total iron‐binding capacity by 50.64 μg/dL (95% CI: 36.21–65.07, P <.05) in CKD patients. Decreases in hepcidin (mean difference [MD] = −23.16, 95% CI: −37.12 to −9.19, P <.05) and ferritin (MD = ‐38.35, 95% CI: −67.41 to −9.29, P <.05) levels were also observed. There was no significant difference in the incidence of adverse events (AEs) (OR: 1.12, 95% CI: 0.95–1.32, P =.17) between the roxadustat and control groups; however, the incidence of serious AEs in the roxadustat group was significantly higher than that in the ESA group (OR: 1.33, 95% CI: 1.06–1.68, P <.05). Conclusion: Roxadustat can significantly improve renal anaemia in CKD patients by increasing Hb level and iron metabolism. However, attention must be paid to the risk of SAEs during treatment.
