Abstract

Abstract Background Cardiac paragangliomas (PGLs) are clinically rare, with hypertension and metabolic changes as the main symptoms. The tumor is highly related to gene mutation, and surgery is presently the effective treatment. Medical history and clinical manifestations of the patient, routine laboratory examinations and imaging examinations, and pathological examination can help the final diagnosis. Case presentation The present study presents a 31-year-old male patient with a left atrial mass. The initial symptom was cough. Cardiac enlargement was found during the chest X-ray. The follow-up imaging examination revealed a left atrial occupying lesion, and the possibility of malignant occupying lesions was not ruled out. The patient underwent surgical resection of the mass. The final pathological result revealed paraganglioma. The thoracic computed tomography review two months after the operation revealed that the original occupying lesion disappeared, and no new lesion was found. Conclusions Pheochromocytomas and paragangliomas (PPGLs) are a kind of neuroendocrine tumors. PPGLs can cause secondary hypertension, and lead to a series of clinical syndromes, including myocardial injury, metabolic changes, and so on. The occurrence of PPGIs is related to gene mutation. Biochemical detection, imaging examination, and genetic testing can help diagnose. The tumor should be surgically removed as soon as possible after the diagnosis. As a functional tumor, PPGLs should be fully prepared before surgery to avoid anesthesia and huge fluctuations in blood pressure during and after surgery, or the occurrence of fatal hypertensive crisis and intractable hypotension after tumor resection. Adequate preoperative preparation directly affects the prognosis of patients after surgery. Therefore, multidisciplinary cooperation before, during, and after the operation is extremely important.

8. Equilibrium reporting strategy: Two rate classes and full insurance.

Abstract

We propose a multiperiod insurance model under a bonus–malus system with two rate classes and consider an insured who has purchased full insurance for her losses. To explore the potential advantage of underreporting her insurable losses, the insured follows a barrier strategy and only reports lossses above the barrier to the insurer. We obtain a unique equilibrium declaration strategy in closed form for a risk‐neutral insured who maximizes her expected wealth, and in semiclosed form for a risk‐averse insured who maximizes her expected exponential utility of wealth, both over an exogenous random horizon. We find that the equilibrium barriers for the two classes are equal and strictly greater than zero, offering a theoretical explanation for the underreporting of insurable losses, a form of ex post moral hazard. Finally, we consider the case of three rate classes and show, through numerical examples, that the equilibrium barriers are not equal. [ABSTRACT FROM AUTHOR]

Abstract

The shipping industry is vital to global trade. Unfortunately, this industry is negatively impacted on a large scale by biofouling, a process whereby unwanted organisms accumulate on submerged surfaces, massively affecting traveling speed and fuel consumption. Fortunately, antifouling coatings have been developed to combat this problem. This review summarizes the process of biofouling and briefly discusses the history of antifouling coating development. Moreover, eight major antifouling coatings are reviewed, including bionic microstructure, self-polishing, fouling and desorption, zwitterionic polymer, self-assembled thin-layer, liquid-smooth surface, conductive, and photocatalytic antifouling coatings. The technical principles, innovation, and advancement of each coating are expounded, and the relevant research progress is discussed. Finally, the remaining issues and challenges in antifouling coatings are discussed, along with their prospects. [ABSTRACT FROM AUTHOR]

20. TSK: A Trustworthy Semantic Keypoint Detector for Remote Sensing Images

Author

Cao, Jingyi, You, Yanan, Li, Chao, and Liu, Jun

Abstract

Keypoint detection aims to automatically locate the most significant and informative points in remote sensing images (RSIs), which directly affects the accuracy of matching and registration. In contrast to the handcrafted keypoint detectors that heavily rely on the morphological gradient of corner, line, and ridge, the learning-based detectors emphasize obtaining reliable keypoints from deep features. However, the limited accuracy of semantics undermines the reliability of keypoints, especially in challenging scenarios characterized by repeated textures and boundaries. Therefore, a novel trustworthy semantic keypoint (TSK) detector is proposed for RSIs. It utilizes a lightweight multiscale feature extraction and fusion network, along with a saliency keypoint localization mechanism, to facilitate keypoint detection. Notably, the TSK detector employed explicit semantics, which is refined with multiple learning strategies about repeatability and representability across the multigranularity reasoning spaces, namely, pixel window, neighbor window, and existence entity. Finally, several metrics about repeatability, matching, and registration are used to evaluate the performance of the TSK detector and other competitive methods. Four RSI datasets, including MICGE, HRSCD, OSCD, and SZTAKI, are used to verify performances. TSK detector achieves competitive performance against existing methods.

Abstract

Meta-analysis Polymorphism Studies of the relationship between male infertility and CYP1A1 polymorphisms are inconclusive. To drive a more precise estimation, we performed a meta-analysis based on 1,060 cases and 1,225 controls from 7 published case-control studies. PubMed and CNKI literature search were conducted to identify all eligible studies investigating such a relationship. Crude odds ratios (ORs) with 95% confidence intervals (CIs) were used to assess the strength of association in the additive model, dominant model, recessive model, and allele-frequency genetic model. In the overall analysis, the frequency of CYP1A1*2A genotype was significantly associated with susceptibility to idiopathic male infertility. Further stratified analysis by ethnicity showed notable association between the polymorphism and risk of idiopathic male infertility in Asians. In conclusion, these results support that the CYP1A1*2A genotype polymorphism mainly contributes to idiopathic male infertility susceptibility in Asians but not in Caucasians.
