摘要：near infrared(NIR) absorbing and emitting dyes are sought after for their potentials in bioimaging and theranostic applications. They are typically not as stable as dyes absorbing and emitting in the visible spectral range, as the result of a reduced HOMO-LUMO band-gap. Also, they are not as efficient fluorescence emitters due to accelerated internal conversion kinetics. In addition, their large conjugative backbone render them high tendency to form aggregate and low aqueous solubility. In this tutorial, we have described a four-step approach for rational design of organic dyes with an overall high-performance to meet the rigorous requirements of biological applications. Also, some background regarding "NIR" is provided along with some recent breakthroughs of the field.

摘要：2017年春夏中国国际时装周T台上,来自法国的素人设计师Arnaud Marquoin-SeignollesCampan de Lanet首次以near WHITE X WHITELESS冠名,呈现了阐述“爱、自由、梦想、骄傲、灵魂及身体,还有自我的精神”的处女设计“SLOGAN SHIRT”系列作品。而WHITELESS品牌本身,更寄寓着一个浪漫的誓约,这是Arnaud献给妻子的礼物。

摘要：2017春夏中国国际国际时装周的T台上,一场只以＂白衬衫＂为主题的秀显得格外独特。这是near WHITE白衬衫全球设计师平台的第一次正式亮相。它的出现,透露着一个设计师集合平台对垂直领域单品的孵化计划。在这场秀中,一位以near WHITE X Timestamp冠名,呈现10套男装100k的设计师王翊翔,抛弃了乏味与枯燥,打破了男士白衬衫的刻板印象。从电子商务专业,转行到Esmode高级时装学院学习服装设计,并以男装设计第一名、综合第二名的优异成绩毕业。已经三次走上中国国际时装周T台的他,这一次以白衬衫为原点,折射出一个品类下的颠覆计划。

摘要：佛罗里达大学零售教育和研究中心主任巴特。魏茨对此表示赞同。他说：“这些新科技有其存在的理由，因为对于很多类型的商品来说——特别是超市的食品——大约70％的购买决定是在商店里形成的。顾客距离商店越近，产生的相关购买信息就越明确。”同时，因为这种系统与存货量以及其他测算人流量和交易量的技术相连接，广告商也能够更清楚地看到其广告是否有效以及如何获益。

摘要：This paper proposes a method to design multichannel cosine modulated filter bank for image compression using multiobjective optimization technique. The design problem is a combination of stopband residual energy, least square error of the overall transfer function of the filter bank, coding gain with dc leakage free condition as constraint. The proposed algorithm uses Non-dominated Sorting Genetic Algorithm (NSGA) to minimize the mutually contradictory objective function by minimizing filter tap weights of prototype filter. The algorithm solves this problem by searching solutions that achieve the best compromise between the different objectives criteria. The performance of this algorithm is evaluated in terms of coding gain and peak signal to noise ratio (PSNR). Simulation results on different images are included to illustrate the effectiveness of the proposed algorithm for image compression application.

摘要：Drug delivery systems(DDSs) have been getting more and more attention in the field of cancer therapy with the development of nanotechnology. But remote and noninvasive controlled drug release for improving treatment efficacy and reducing side effects faces great challenge. We report a kind of 'smart' nanocomposites(NCs) that is sensitive to the surrounding temperature by grafting a layer of thermosensitive polymer, poly(N-isopropylacrylamide)(pNIPAm),on the surface of single Cu_7S_4 nanoparticle(NP) via atomtransfer radical polymerization(ATRP). These NCs demonstrate a photothermal conversion efficiency of 25.4% under808-nmnear infrared(NIR) light irradiation and a drug loading content of 19.4%(drug/total NCs, w/w) with a lower critical solution temperature(LCST) of ~38°C. At normal physiological temperature(37°C), only 10.8% of the loaded doxorubicin(DOX) was released at physiological pH value(pH7.4) within 10 h. In the presence of 808-nm irradiation, due to the temperature increment as a result of photothermal effects,DOX was rapidly released.

摘要：10月27日,near WHITE白衬衫首次携其2017春夏系列亮相中国国际时装周。本场只以“白衬衫”为主题的秀背后其实是一个设计师集合对垂直领域单品的孵化计划。本次首秀,集合了near WHITE白衬衫平台第一次推向市场的5组设计师的60套look。随着新一代消费主力的成熟和逐渐成为消费领域的决定力量,“独特”的消费追求成为人性深处的消费推动力。

摘要：在NFC技术中,CLF芯片与SIM卡的连接是一个重要问题,本文提出了一种具有自主知识产权的CLF与SIM卡的通信方法,采用新的调制解调方式,使得S2信号在S1信号高低电平时都能传输,实现单线连接NFC与SIM卡,以及它们之间的全双工通信。通过对该方法进行电路级的设计和仿真,验证了该方法的正确性和稳定性。

摘要：□□据2006年2月15日美国《每日防务》报道,美国空军科学咨询委员会(AFSAB)发布了“在近太空高度持久执行任务”(Persistence at near Space Altitudes)研究项目的报告,提出了美国空军近期(到2010年)、中期(到2020年)和远期(2020年以后)近太空飞行器的发展和选择建议。该报告认为,与气球或飞艇相比,高空长航时无人机是美国空军在近期内利用“近太空”这一尚未全面、系统地开发和利用的空域,执行持久高空监视、情报搜集和通信中继等任务的最好选择。2010年之前,高空长航时信息无人机,如美国诺格公司的RQ-4“全球鹰”(Global Hawk),在执行高空持久任务方面将可能替代低轨道侦察卫星。而自由飘浮式高空气球的军事用途则相对有限,因为它对天气,尤其是风过于敏感。对于高空飞艇,报告认为它是一种有前景的选择,但还需要等待有关技术取得进步后才具备可行性。因此该报告建议,美国空军目前应暂缓对高空飞艇型号项目的大量投资,而应关注美国国防高级研究计划局(DARPA)和导弹防御局(MDA)在这方面的活动,同时应针对某些可促使高空飞艇设计在未来发展得更成熟,以及能增强高空无人机甚至气球...
