[内容简介]
The next generation wireless networks need to accommodate 1000x more data traffic and 50x more devices than current networks. Since the spectral resources are scarce, particularly in bands suitable for wide-area coverage, the main improvements need to come from a more aggressive spatial reuse of the spectrum; that is, many more concurrent transmissions are required per unit area. This is achieved by the Massive MIMO (massive multi-user multiple-input multiple output) technology, where the access points are equipped with hundreds of antennas and can serve tens of users on each time-frequency resource by spatial multiplexing. The many antennas give a great separation of users in the spatial domain, which is a paradigm shift from conventional multi-user technologies that mainly relied on user separation in the time or frequency domains. In recent years, Massive MIMO has gone from being a mind-blowing theoretical concept to one of the most promising 5G-enabling technologies. Everybody seems to talk about Massive MIMO, but do they all mean the same thing? What is the canonical definition of Massive MIMO? What are the differences from the classical multi-user MIMO technology from the nineties? What are the key characteristics of the transmission protocol and why is the protocol designed in that way? Are there any widespread misunderstandings? This tutorial answers all these questions. It covers the main motivation and properties, fundamental communication-theoretic results that quantifies the gains, and survey the state-of-the-art regarding spectral efficiency, radio resource management, energy efficient network design, and the impact of hardware impairments. 1.新一代无线网络需要容纳更多的通信设备,并保证更高的通信速度,为了解决频谱资源受限的问题,需要采用大规模MIMO技术,即配备数百个天线的接入点通过空分复用技术服务数十个用户。空间域中,很多天线给用户提供了很大的分离,相对于在时间和空间上分离用户的传统多用户技术来说,这是思考模式的转变。 2.最近,大规模MIMO已经从使人兴奋的理论概念发展为最具有前景的5G技术之一。很多人都在谈论大规模MIMO,但大规模MIMO的权威定义是什么?经典的多用户MIMO技术和九十年代有哪些不同? 3. 传输协议有哪些特点?为什么这么设计?是否有广泛误解的地方?这次讲座将对意义、特性、重要通信理论结果、频谱效率的最新研究进展、无线资源管理、网络设计及硬件不匹配的影响进行讲解。

We report here on experimental studies of well-defined surfaces to investigate the role of the electrode surface in pyridine-catalyzed CO2 reduction, which is reported to be associated with high yields for methanol and formic acid. Ambient pressure photoelectron spectroscopy (APPES) was used to spectroscopically identify in situ surface-bound species formed by the interaction of water on GaP(110), the most stable surface of GaP, at pressures up to 1 Torr. The data show that the interaction with water is characterized by the presence of a partially dissociated adlayer, with Ga-OH, P-H, and adsorbed molecular H2O species detected on the surface. This is consistent with previously published theoretical work that predicts the presence of this layer. In addition, we used isobaric APPES measurements at elevated pressures to probe the thermal stabilities of adsorbed species as well as the oxidation of surface Ga and P. We observe the surface hydride to be remarkably stable in the presence of water, which is notable given the critical role of hydride transfer to catalysts and CO2 during chemical fuel synthesis reactions in aqueous environments. It is hypothesized that the high observed stability of the hydride on GaP may contribute to its associated remarkable near-100% faradaic efficiency for methanol generation by solar-driven CO2 reduction. We have also obtained orbital-resolved information on the adsorption state of pyridine (C5H5N) on GaP(110) using scanning tunneling microscopy (STM). By examining the distribution of unoccupied molecular orbitals with high spatial and energetic resolution, we showed that scanning probe techniques can be used to positively identify the sites on pyridine susceptible to nucleophilic attack, consistent with frontier orbital theory. This technique can be used to explore the local reaction centers of adsorbed catalysts relevant to artificial photosynthesis. Our observations of the stable adsorption of both H and pyridine on this surface is notable, because it characterizes the proposed precursor state for the formation of adsorbed dihydropyridine, which could be a key hydride-shuttling catalyst for heterogeneous CO2 reduction. 通过对已知的、有明确定义的各种表面展开研究,我们试图探索在吡啶催化还原CO2的物理过程中电极表面所起到的作用,报道称这一物理过程有助于提高甲醇和甲酸的收率。环境压力光电能谱用来光谱分析识别水与GaP(110)相互作用形成的原位表面结合物质,GaP(110)是压力上升到1Torr范围内,表面最稳定的GaP。实验数据显示,与水相互作用的特点是存在一个部分解离吸附层,在表面检测到了Ga-OH, P-H, 和吸附态分子水。这与之前发表的关于预测这一吸附层存在的理论性研究成果相一致。此外,我们采用等压环境压力光电能谱在高压条件下探测吸附态物质的热稳定性以及表面Ga和P的氧化过程。我们观察到,在水存在的条件下,表面氢化物是非常稳定的,值得注意的是在水环境下,在化学燃料合成反应中氢化物行催化剂和二氧化碳转移是非常关键的。可以推测,氢化物在GaP上的高稳定性有助于将太阳能驱动二氧化碳还原制取甲醇过程中的电感效率提高到接近100%。借助于隧道扫描显微镜,我们也获得了GaP(110)上吸附态吡啶(C5H5N)的轨道-分辨信息。通过研究具有高空间分辨率和高能量分辨率的未占用分子轨道的分布,我们发现,扫描探针技术可以较好地确认吡啶上对亲核攻击较为敏感的位点,且检测结果与边界轨道理论一致。这项技术可以用于探测与人工光合作用相关的吸附催化剂的反应活性中心。我们对表面上氢和氢化物的稳定吸附的观测结果是应该值得注意的,因为它表征着吸附态吡啶形成的前体,可能是一种关键用于非均相CO2还原的氢化物-穿梭催化剂。

[内容简介]
The classical approaches to managing wireless interference are waveform orthogonality, such as frequency-division multiple access (FDMA), and adequate spatial separation of co-channel transmitters. Point-to-point multiple-input-multiple-output (MIMO) and multi-user MIMO, which allows interference in the waveform domain and relies on multiple antennas at the base stations or access points to separate the waveforms, is now in LTE and WiFi standards. In this talk, we will focus on some nonlinear and distributed methods of managing interference, specifically interference cancelation (IC) and network MIMO. IC is a well-known nonlinear technique that can be implemented in a single-antenna receiver and network MIMO is a form of multi-user MIMO that uses spatially distributed but jointly processed access points. For both of these, there are few reports on practical implementation and experimental performance characterization. The use cases that motivate our work are transmit-only wireless sensor networks and scalable high-capacity WiFi. For IC in transmit-only WSNs, based on analysis and measurement, we propose a new model for the residual error of IC for MSK packets. We show that use of the popular model instead of the new model can lead to significant errors in network analysis. We also explore a low-cost network MIMO architecture for transmit-only WSNs. For scalable WiFi, we explore a hybrid combination of nonlinear precoding and interference (IA) alignment, which improves the BER performance and has lower complexity compared with IA alone.

[内容简介]
Most existing methods of human attribute recognition are part-based and the performance of these methods is highly dependent on the accuracy of body-part detection, which is a well known challenging problem in computer vision. In this talk, I will introduce a new method to recognize human attributes by using CAM (Class Activation Map) network, as well as an unsupervised algorithm to refine the attention heat map, which is an intermediate result in CAM and reflects relevant image regions for each attribute. The proposed method does not require the detection of body parts and the prior correspondence between body parts and attributes. The proposed methods can achieve comparable performance of attribute recognition to the current state-of-the-art methods.

[内容简介]
Physiologic systems are regulated by interacting mechanisms that operate across multiple spatial and temporal scales. The output variables of these systems often exhibit complex fluctuations that are not simply due to "contaminative" noise but contain information about the underlying dynamics.Traditional methods quantify the degree of regularity of a time series by evaluating the appearance of repetitive patterns. However, there is no straightforward correspondence between regularity, which can be measured by entropy-based algorithms, and complexity. Intuitively, complexity is associated with "meaningful structural richness", which, in contrast to the outputs of random phenomena, exhibits relatively higher regularity.

[内容简介]
Thermal transport plays an important role in energy conversion efficiency and device reliability. There were significant progresses over the past two decades on utilizing micro/nanostructures for enhancing or reducing heat transfer owing much to the challenging needs in energy conversion, storage and thermal management systems. Yet, cost-effectiveness plays a key role in engineering micro/nanostructures for heat transfer applications. In this talk, I will highlight two examples that we currently work on by utilizing scalable manufactured micro/nanostructured surfaces for enhancing heat transfer processes: phase-change heat transfer and radiative heat transfer. These surfaces are expected to play an important role in future thermal and energy systems. 热传输在能量转换效率和器件可靠性方面起着重要的作用。 在过去二十年中,由于能量转换、储存和热管理系统的挑战性需求,利用微/纳米结构来增强或减少热传递方面取得了重大进展。 然而,成本效益在微/纳米结构的传热应用中起关键作用。 在这个演讲中,我将强调我们目前通过利用可扩展制造的微/纳米结构表面来增强传热过程的两个例子:相变传热和辐射热传递。 预计这些表面将在未来的热能和能源系统中发挥重要作用。
