Dear editor, In the daily operation of metro systems, external interferences(e.g., signal system malfunction, bad weather) that can affect normal train operation are inevitable. Hence,effective train regulation measures are necessary to ensure service quality and efficient operation [1, 2]. With the explosive growth in the urban rail transit ridership in recent years,

OBJeCTIVe: To describe the key systems used for Traditional Chinese Medicine(TCM) ***: The TCM classifications used in the International Classification of Diseases-9 Clinical Modification(ICD-9-CM) volume 3, the ICD-10 Procedure Coding System, the International Classification of Health Interventions, and the Medical Subject Headings(Me SH) and Chinese Traditional Medicine and Materia Medica Subject Headings(TCMe SH) thesauruses were compared regarding descriptive terms, structure, and features of TCM ***: The National Library of Medicine's Me SH thesaurus is ubiquitous. The ICD-9-CM(volume 3),ICD-10 Procedure Coding System, and International Classification of Health Interventions cover insufficient concepts of TCM, and cannot be used directly as classification systems for TCM interventions. In contrast, the TCM contents of the TCMe SH thesaurus are complete, systematic, and detailed, and its hierarchical structure can be used for effective TCM ***: TCM classification is very limited and flawed. The Me SH thesaurus helps decrease the detrimental effect of the language barrier. Similarly, the TCMe SH thesaurus can help those without full command of the Mandarin language to access Chinese literature, but the value of searches using TCMe SH could be improved by collaborative working with Information Specialists who are fluent in Mandarin and understand TCM.

1 Introduction As wireless technology continues to expand,there is a growing concern about the efficient use of spectrum *** though a significant portion of the spectrum is allocated to licensed primary users(PUs),studies indicate that their actual utilization is often limited to between 5%to 10%[1].The underutilization of spectrum has given rise to cognitive radio(CR)technology,which allows secondary users(SUs)to opportunistically access these underused resources[2].However,wideband spectrum sensing,the key of CR,is limited by the need for high-speed analog-to-digital converters(ADCs),which are costly and *** spectrum sensing(CSS)addresses this challenge by employing sub-Nyquist rate *** efficiency of active transmission detection heavily depends on the quality of spectrum reconstruction.

This paper proposes cooperative adaptive control schemes for a train platoon to improve efficient utility and guarantee string stability. The control schemes are developed based on a bidirectional strategy, i.e., the information of proximal（preceding and following） trains is used in the controller design. Based on available proximal information（prox-info） of location, speed, and acceleration, a direct adaptive control is designed to maintain the tracking interval at the minimum safe distance. Based on available prox-info of location, an observer-based adaptive control is designed to achieve the same target, which alleviates the requirements of equipped sensors to measure prox-info of speed and acceleration. The developed schemes are capable of on-line estimating of the unknown system parameters and stabilizing the closed-loop system, the string stability of train platoon is guaranteed on the basis of Lyapunov stability theorem. Numerical simulation results are presented to verify the effectiveness of the proposed control laws.

extrusion freeforming can be used for the rapid prototyping of millimeter-wave electromagnetic bandgap (eBG) structures. In this work, an alumina-polymer paste with a relatively high volatility solvent (propanol) was used and the characteristics of the ceramic paste, particularly the rheological features are described. The advantage of high volatility solvent is that the viscosity and elastic modulus of the paste are increased sharply as the solvent evaporates. Thus, the rigidity of the extruded filament is quickly increased as a small amount of solvent evaporates. Finally, by employing this procedure, different eBG structures such as 2-D, 3-D woodpile and aperiodic structures were fabricated and their bandgaps were measured. The experimental results show that extrusion freeforming is a relatively simple and easy method to fabricate these woodpile structures with a bandgap in the 90-110 GHz region.

实现对钝力性损伤中个体死亡率更佳的评估。损伤严重程度评分不仅是国际公认的用于评价多发伤严重程度的标准,还是一种适用于现场数据的数学方法。目前的研究已经证明,损伤严重程度评分与吉布斯-玻尔兹曼熵存在比例关系,也与香农信息熵具有比例关系。推导出一种钝力性损伤包括并发症死亡率的新的熵测度,将其应用于早期公开的数据,获得了很好的一致性。应用熵测度对老年人并发症进行研究,发现较低程度损伤中老年人并发症的死亡率明显高于普通人群。上述的研究带来了针对当前新车评价程序,以及到底新车评价程序能对最弱势交通参与者起到何种程度保护的疑问。
