Head and neck cancer (HNC) consists of a group of malignancies affecting closely related anatomical regions of the upper aerodigestive tract (UADT), including the oral cavity, salivary glands, upper and lower jaw bones and facial skin; the nasal cavity, paranasal sinuses, pharynx, larynx and thyroid gland (although the latter is often excluded and considered as part of endocrine neoplasms). Of these, 90% of HNCs are histologically squamous cell carcinomas originating from the mucosal lining. These malignancies are strongly associated with certain environmental and life-style risk factors, principally tobacco in both smoked and smokeless forms, excessive alcohol consumption, diets poor in antioxidants and essential micronutrients, UV light, chemicals used in certain workplaces, and viruses, principally certain strains of human papillomavirus (HPV) and Epstein-Barr virus (EBV). These cancers are frequently aggressive in their biological behaviour with local invasion and metastasis to lymph nodes in the neck. Since most patients are already at late stages of disease at the time of diagnosis, the desirable practice of early diagnosis (first sign of the malignant lesion at an initial stage ) and early treatment, a critical priority to save lives and retain quality of life, is difficult to implement. Thus, primary prevention has been set as a key goal. This article aims to reinforce the basic knowledge of aetiology, key risk factors related to the development of head and neck cancer, basic features of clinical appearance of this group of cancers, and strategies for prevention and early detection. We also suggest basic research strategies on the basis of current knowledge, which should ultimately lead to the improvement of clinical management.

针对网络控制系统(NCS)具有不确定时延的特性,提出了将广义预测控制(GPC)应用于网络控制系统的思想。为了克服模型失配和系统不确定性的影响,基于BP神经网络建立一个误差的预测模型,用误差预测值对输出预测值进行补偿,构成新型的广义预测控制算法,并采用了平滑滤波的加权输入控制律。在网络控制系统中,测试了网络数据传输的随机延迟时间特性,比较了GPC和具有BP网络预测误差补偿的GPC两种控制方法,验证了具有BP网络预测误差补偿的GPC在模型失配时的更好的控制性能。

在空中交通管理和民航机场运营过程中,从过去的运营中获得的经验对于设计合理的策略至关重要。因此,本文使用大量时空飞行数据来识别相似的航空交通和延误模式,这对于更好地了解航空系统和制订管理决策至关重要。但是,由于数据集隐含了复杂的依赖关系以及高维时空之间的交互作用,因此挖掘数据中的重要特征和模式非常具有挑战性。本文提出了高维历史飞行数据的张量因子分解框架。我们通过潜在类别分析模型,并使用2014—2017年中国224个机场的空中交通运行数据证明了该框架的有效性。研究发现每个维度可以清晰地代表不同的运行模式。为了证明这些模式的有效性,我们创建了一个估计模型,该模型可实现对航班延误程度的初步判断。上述结果可以根据历史情景获得的经验,帮助机场运营商和空中交通管理人员更好地了解空中交通和延误模式。
Understanding and addressing the environmental risk of microplastics
《环境科学与工程前沿(英文)》 2023年 第17卷 第1期 doi: 10.1007/s11783-023-1612-5
Over the past decades, the plastic production has been dramatically increased. Indeed, a category of small plastic particles mainly with the shapes of fragments, fibers, or spheres, called microplastics (particles smaller than 5 mm) and nanoplastics (particles smaller than 1 μm) have attracted particular attention. Because of its wide distribution in the environment and potential adverse effects to animal and human, microplastic pollution has been reported as a serious environment problem receiving increased attention in recent years. As one of the commonly detected emerging contaminants in the environment, recent evidence indicates that the concentration of microplastics show an increasing trend, for the reason that up to 12.7 million metric tons of plastic litter is released into aquatic environment from land-based sources each year. Furthermore, microplastic exposure levels of model organisms in laboratory studies are usually several orders of magnitude higher than those found in environment, and the microplastics exposure conditions are also different with those observed in the environment. Additionally, the detection of microplastics in feces indicates that they can be excreted out of the bodies of animal and human. Hence, great uncertainties might exist in microplastics exposure and health risk assessment based on current studies, which might be exaggerated. Policies reduce microplastic emission sources and hence minimize their environmental risks are determined. To promote the above policies, we must first overcome the technical obstacles of detecting microplastics in various samples.

Advances in airborne microorganisms detection using biosensors: A critical review
《环境科学与工程前沿(英文)》 2021年 第15卷 第3期 doi: 10.1007/s11783-021-1420-8
Humanity has been facing the threat of a variety of infectious diseases. Airborne microorganisms can cause airborne infectious diseases, which spread rapidly and extensively, causing huge losses to human society on a global scale. In recent years, the detection technology for airborne microorganisms has developed rapidly; it can be roughly divided into biochemical, immune, and molecular technologies.
