生成式对抗网络(Generative adversarial networks,GAN)是主要的以无监督方式学习深度生成模型的方法之一.基于可微生成器网络的生成式建模方法,是目前最热门的研究领域,但由于真实样本分布的复杂性,导致GAN生成模型在训练过程稳定性、生成质量等方面均存在不少问题.在生成式建模领域,对网络结构的探索是重要的一个研究方向,本文利用胶囊神经网络(Capsule networks,CapsNets)重构生成对抗网络模型结构,在训练过程中使用了Wasserstein GAN(WGAN)中提出的基于Earth-mover距离的损失函数,并在此基础上加以条件约束来稳定模型生成过程,从而建立带条件约束的胶囊生成对抗网络(Conditional-CapsuleGAN,C-CapsGAN).通过在MNIST和CIF AR-10数据集上的多组实验,结果表明将CapsNets应用到生成式建模领域是可行的,相较于现有类似模型,C-CapsGAN不仅能在图像生成任务中稳定生成高质量图像,同时还能更有效地抑制模式坍塌情况的发生.

为了实现碳中和、达成巴黎协定低增温目标,人为排放将会大幅减少,未来大气中二氧化碳和气溶胶浓度会共同呈现下降趋势.本研究利用通用地球系统模式进行固定气溶胶模拟实验,探究碳中和情景下人为气溶胶对地表温度的影响.结果发现,未来人为气溶胶减少产生的增暖效应将叠加在二氧化碳减少引起的降冷效应之上,使地表增温幅度扩大、降温速率减慢,从而延长实现巴黎协定低增温目标所需时间;在未来人为气溶胶减少背景下,地表温度出现不均匀变化,当其他地区出现长期变暖趋势时,北大西洋副极地地区出现长期变冷趋势.这主要是由于大西洋经向翻转流持续减弱引起的海洋向北热输送减少所致.本研究表明在规划碳中和的具体跨径时,需要考虑人为气溶胶对气候系统的重要调控作用.

The dendrite growth of Li anodes severely degrades the performance of lithium-oxygen(Li-O2) ***, hybrid solid electrolyte(HSE) has been regarded as one of the most promising routes to tackle this problem. However, before this is realized, the HSE needs to simultaneously satisfy contradictory requirements of high modulus and even, flexible contact with Li anode, while ensuring uniform Li+distribution. To tackle this complex dilemma, here, an HSE with rigid Li1.5Al0.5Ge1.5(PO4)3(LAGP)core@ultrathin flexible poly(vinylidene fluoride-hexafluoropropylene)(PVDF-HFP) shell interface has been developed. The introduced large amount of nanometer-sized LAGP cores can not only act as structural enhancer to achieve high Young’s modulus but can also construct Li+diffusion network to homogenize Li+distribution. The ultrathin flexible PVDF-HFP shell provides soft and stable contact between the rigid core and Li metal without affecting the Li+distribution, meanwhile suppressing the reduction of LAGP induced by direct contact with Li metal. Thanks to these advantages, this ingenious HSE with ultra-high Young’s modulus of 25 GPa endows dendrite-free Li deposition even at a deposition capacity of 23.6 m ***, with the successful inhibition of Li dendrites, the HSE-based quasi-solid-state Li-O2battery delivers a long cycling stability of 146 cycles, which is more than three times that of gel polymer electrolyte-based Li-O2battery. This new insight may serve as a starting point for further designing of HSE in Li-O2batteries, and can also be extended to various battery systems such as sodium-oxygen batteries.
