Biological chip technology to quickly batch select optimum cryopreservation procedure

YU Lina, LIU Jing, ZHOU Yixin, HUA Zezhao

《能源前沿（英文）》 2007年第1卷第3期页码 316-321 doi: 10.1007/s11708-007-0046-2

摘要： In the practices of cryobiology, selection of an optimum freeze/thawing program and an idealistic cryoprotective agent often requires rather tedious, time consuming and repetitive tests. Integrating the functions of sample preparation and viability detection, the concept of biochip technology was introduced to the field of cryopreservation, aiming at quickly finding an optimum freezing and thawing program. Prototype devices were fabricated and corresponding experimental tests were performed. It was shown that microflow-channel chip could not offer a high quality solution distribution. As an alternative, the spot-dropping chip proved to be an excellent way to load the sample quickly and reliably. Infrared thermal mapping on such a chip showed that it had a rather uniform heat transfer boundary. Applying the spot-dropping chip combined with the thermoelectric cooling device, the final output of cryopreservation of multiple samples was tested, and the optimal freeze/thawing program as well as the potentially best concentration of the cryoprotective agent was found by analyzing the results. Further, application of this technique to measure the thermo-physical properties of the cryo-protective agent was also investigated. The study demonstrated that a biochip with integrated automatic loading and inspection units opens the possibility of a massive optimization of the complex cryopreservation program in a quicker and more economical way.

A prototype online database-enabled design framework for wind analysis/design of low-rise buildings

Dae Kun KWON,Ahsan KAREEM,Deepak KUMAR,Yukio TAMURA

《结构与土木工程前沿（英文）》 2016年第10卷第1期页码 121-130 doi: 10.1007/s11709-015-0329-3

摘要： This study presents a development of an advanced cyberbased database-enabled design module for low-rise buildings (DEDM-LR) which provides estimation of the wind-induced responses for main wind force resisting frames by making direct use of pressure time histories measured at a large number of pressure taps over a suite of building models. These responses may be considered in lieu of code-specified load effects in which the overall accuracy may be influenced by the inherent simplifications in codes. In addition, this new automated approach is particularly attractive and advantageous as it allows a web-based online analysis/design via intuitive user-friendly interfaces for both the input and output in terms of familiar web-style forms that are nowadays very common in most of web-based services. Presently, the DEDM-LR hosts an aerodynamic database developed by the Tokyo Polytechnic University (TPU), Japan for a variety of building configurations like flat, gable, and hip roofs under suburban terrain flow condition with immediate application to other databases. The paper shows the efficacy and validity of the DEDM-LR by walking through its details and examples on selected gable-roofed buildings. The architecture of DEDM-LR platform offers the ability to pool resources by hosting other databases that may become available in the near future.

何川,封坤,晏启祥,齐春

《中国工程科学》 2012年第14卷第10期页码 65-72

摘要：

针对我国第一条水下铁路盾构法隧道——狮子洋隧道，采用“多功能盾构隧道结构体试验系统”装置原型管片衬砌结构，在通缝和错缝不同的拼装方式下进行了原型结构加载试验，对其结构力学性能进行深入探讨。试验结果表明，不同水压条件下管片衬砌结构力学特征不同，尤其是当结构开裂后，高水压对于结构内力与形变的发展有明显的减缓作用。狮子洋隧道采用的榫式接头管片结构在通缝与错缝拼装下的破坏特征不同，通缝拼装时结构在高水压条件下纵缝附近区域易发生局部剪切破坏，该研究成果可为同类工程的设计提供有价值的参考。

Acoustic analysis of lightweight auto-body based on finite element method and boundary element method

LIANG Xinhua, ZHU Ping, LIN Zhongqin, ZHANG Yan

《机械工程前沿（英文）》 2007年第2卷第1期页码 99-103 doi: 10.1007/s11465-007-0017-7

摘要： A lightweight automotive prototype using alternative materials and gauge thickness is studied by a numerical method. The noise, vibration, and harshness (NVH) performance is the main target of this study. In the range of 1 150 Hz, the frequency response function (FRF) of the body structure is calculated by a finite element method (FEM) to get the dynamic behavior of the auto-body structure. The pressure response of the interior acoustic domain is solved by a boundary element method (BEM). To find the most contributing panel to the inner sound pressure, the panel acoustic contribution analysis (PACA) is performed. Finally, the most contributing panel is located and the resulting structural optimization is found to be more efficient.

《机械工程前沿（英文）》 2020年第15卷第4期页码 600-609 doi: 10.1007/s11465-020-0597-z

摘要： A primary permanent-magnet linear motor (PPMLM) has a robust secondary structure and high force density and is appropriate for direct-drive mechanical press. The structure of a four-side PPMLM drive press is presented based on our previous research. The entire press control system is constructed to realize various flexible forming processes. The control system scheme is determined in accordance with the mathematical model of PPMLM, and active disturbance rejection control is implemented in the servo controller. Field-circuit coupling simulation is applied to estimate the system’s performance. Then, a press prototype with 6 kN nominal force is fabricated, and the hardware platform of the control system is constructed for experimental study. Punch strokes with 0.06 m displacement are implemented at trapezoidal speeds of 0.1 and 0.2 m/s; the dynamic position tracking errors are less than 0.45 and 0.82 mm, respectively. Afterward, continuous reciprocating strokes are performed, and the positioning errors at the bottom dead center are less than 0.015 mm. Complex pulse trajectories are also achieved. The proposed PPMLM drive press exhibits a fast dynamic response and favorable tracking precision and is suitable for various forming processes.

《工程（英文）》 2023年第29卷第10期页码 198-206 doi: 10.1016/j.eng.2022.10.005

摘要：

理想的透明微波吸收器具有高光学透过率和强微波吸收能力，但是若其吸收性能固定，则会限制微波吸收器的应用。本文提出了一种基于二氧化钒(VO₂)薄膜的透明热可调微波吸收器。理论计算和实验结果表明，所提出的吸波器在620 nm波长处可以实现84.9%的高光学透过率，同时通过控制温度，15.06 GHz频点处的反射损耗可在-4.257 dB到-60.179 dB范围内调谐并且在523.75 K温度时实现近1吸收。同时，仅通过调控图案化VO₂薄膜的占空比即可改变实现近1吸收时的温度。所提出的基于VO₂薄膜的吸波器具有组成简单，光学透过率高，微波吸收性能热可调，调制深度大，温度调节范围可控等优点，因此有望应用于可调传感器、热发射器、调制器、热成像仪、辐射热测定器和光电器件中。

抑制FLT3 ——急性髓系白血病分子靶向治疗的原型 Review

Meira Yisraeli Salman, Jacob M. Rowe, Nir Weigert

《工程（英文）》 2021年第7卷第10期页码 1354-1368 doi: 10.1016/j.eng.2021.05.020

摘要：

急性髓系白血病（AML）的现代治疗始于1973年，首例柔红霉素和阿糖胞苷联合治疗法的成功随后拯救了大约45%的患者。准确的AML诊断依赖于形态学方法，其最初仅由细胞化学手段辅助。与急性淋巴细胞白血病（ALL）不同，至少在20世纪70年代和80年代，免疫分型在AML的诊断中几乎不起作用。可靠的细胞遗传学方法的出现为AML的预后发展带来了翻天覆地的变化。通过核型分析，可以对不同的AML实现分类与分层，以进行各种治疗。借助细胞上抗原标记物的免疫表型鉴定，独特的突变图谱可以里程碑式地进一步对 AML 患者进行分类。所有的这些进展都随着对肿瘤负荷[即微小残留病变（minimal residual disease, MRD）]的重要性的理解而成为AML患者管理的关键。MRD的疗效在过去10年迅速发展，其特异性从免疫分型的10^-3发展到聚合酶链反应（PCR）的10^-4（且仅对于部分AML患者有效），并最终在具有下一代测序（NGS）技术的灵敏度极高的细胞中发展至10^-5甚至10^-6。所有这些进步都促进了个性化医疗概念的发展，并带来了可以准确用于特定诊断亚型的靶向药物。可以精准预测与测量其响应。这些靶向药物现已成为AML管理的基础，其疗效显著提高，而毒性则显著下降。本文的重点是研究最为深入的AML靶向药物之一——FMS样酪氨酸激酶3（FLT3）抑制剂，它影响了AML的预后与治疗。作为已被批准的其他新兴靶向药物以及目前正在开发的靶向药物的原型，本文将选择性地对FLT3抑制剂展开详细讨论。

《信息与电子工程前沿（英文）》 2020年第21卷第6期页码 809-962 doi: 10.1631/FITEE.1900075

摘要：随着应用程序规模和超级计算机体系结构复杂性的迅速增加，拓扑映射的重要性愈加凸显。高通信成本已成为超级计算机上运行的应用程序性能的主要限制因素。为避免不合适的映射策略可能带来的较差通信性能，提出一种启发式优化拓扑感知映射算法（OHTMA）。该算法旨在最小化用于测量映射结果的字节跳跃度量。OHTMA结合贪婪启发式算法和基于对交换的优化方法，减少了远程通信数量，有效增强了通信局部性。在天河三号E级原型机的实验结果表明，OHTMA算法可显著降低通信成本。

摘要：

可重复使用运载火箭是降低太空运输成本的一种新途径。着陆机构是可重复使用运载火箭的重要组成部分，起到着陆支撑和吸收冲击的作用。本文提出了一种新型的可展开着陆机构（LDLM）。采用Watt-II型六杆机构，利用连杆变分法得到优选构型。本文建立了多目标优化范式，使得可展开着陆机构具有着陆支撑区域大、轻量化、连杆内力合理等优点，在此基础上，利用多目标遗传算法（NSGA-II）进化算法得到了可展开式着陆机构设计的最优尺寸参数。本文研制了全功能可重复使用运载火箭缩比样机，通过集成重力控制的展开方案促进展开动作，避免全范围驱动，采用双重锁紧机构提高展开状态时结构的可靠性，采用多级铝蜂窝缓冲器提供可靠的减震性能。实验结果表明，所提出的可展开式着陆机构能够提供快速平稳的展开（持续时间小于1.5 s），且对舱体的姿态扰动较小（偏航和俯仰波动小于6°）。此外，该机构在0.2 m自由落体测试中提供了足够的冲击衰减（加速度峰值小于10g）。所提出的可展开着陆机构可作为未来可重复使用运载火箭潜在的腿式起落架替代方案。
