Manipulating light dynamics in optical microcavities has been made mainly either in real or momentum space. Here we report a phase-space tailoring scheme, simultaneously incorporating spatial and momentum dimensions, to enable deterministic and in situ regulation of photon transport in a chaotic microcavity. In the time domain, the chaotic photon transport to the leaky region can be suppressed, and the cavity resonant modes show stronger temporal confinement with quality factors being improved by more than 1 order of magnitude. In the spatial domain, the emission direction of the cavity field is controlled on demand through rerouting chaotic photons to a desired channel, which is verified experimentally by the far-field pattern of a quantum-dot microlaser. This work paves a way to in situ study of chaotic physics and promoting advanced applications such as arbitrary light routing, ultrafast random bit generation, and multifunctional on-chip lasers.

Methods of domain adaptation can be roughly divided into two categories: feature-based and instance-based. In summary, both methods are a kind of weighted-learning, but feature-based gives weight to features and instance-based gives weight to instance. Generally, feature-based is more effective than instance-based. However, these two methods can be combined to improve the accuracy of only the feature-based method. In this paper, we do it using the neural network model, where we use the feature-based method as SVD and instance-based method proposed in our previous work. In the experiment for the Amazon dataset, we confirmed the effectiveness of the proposed method.

Bidirectional Encoder Representations from Transformers (BERT) is a stacked (12 or 24) model of multi-head attention applied in the transformers. The multi-head attention of each layer outputs a word embedded expression sequence corresponding to the input word sequence. When BERT is applied to the feature base, the output is the word-embedded expression column of the highest layer used in each task. On the other hand, in domain adaptation, projecting the data of each region onto the common subspace of the source and target domains is an effective approach. When constructing a feature vector on a common subspace from a word-embedded representation output of the BERT, the most significant layer depends on the task learning task assigned to BERT, so is not necessarily more significant than the word-embedded representation of a lower layer. Layers are suboptimal for regional adaptation. Here we confirm this concept on unsupervised domain adaptation of an emotion analysis.

Variable-length hierarchical names of Named data networking (NDN) content bring about intuitive issues for both content routing and large-scale forwarding. Bloom filters can accelerate hash-based NDN content discovery with a false positive probability. In this paper, we propose ECBF, a component-based bloom filter scheme to enhance the reliability of bloom filters. We exploit the hierarchical characteristics of NDN content names and store them into different bloom filters in a component-based way, and then we present a correlation validation policy to check whether the names exist. Finally, we introduce an ECBF-based content discovery scheme BCD. ECBF and the correlation validation value are stored in a fast on-chip memory, and cryptographic check values of content names and related information are respectively stored in an off-chip memory of intermediate routers. This design not only improves the effectiveness of content discovery, but also reduces the additional memory throughput. We experimentally demonstrate that BCD can provide a more than twice reduction of false probability compared with the primary bloom filter methods. Besides, BCD can economize about 40% memory consumption. © 2019 IEEE.

Despite the deep neural networks(DNN) has achieved excellent performance in image classification researches, the training of DNNs needs a large of clean data with accurate annotations. The collect of a dataset is easy, but it is difficult to annotate the collecting data. On the websites, there exist a lot of image data which contains inaccurate annotations, but training on these datasets may make networks easier to over-fit the noisy labels and cause performance degradation. In this work, we propose an improved joint optimization framework, which mixed the mix-up entropy and Kullback-Leibler (KL) entropy as the loss function. The new loss function can give the better fine-tuning after the framework updates both the label annotations. We conduct experiments on CIFAR-10 dataset and Clothing1M dataset. The result shows the advantageous performance of our approach compared with other state-of-the-art methods. Copyright © 2019, The Authors. All rights reserved.

作者： Tianyi Luo Major in Electrical and Computer Engineer College of Engineering The Ohio The Ohio State University 43201

The Book Stores industry has had its pages ruffled over the near half decade. Despite a strengthening domestic economy and rising per capita disposable income, the industry continues to experience decline. The business had negative annual growth since 2013, and there is no sign of stopping this trending. It is highly duo to two main factors, the change of consumer purchasing preference and external competitors rising. When such a traditional business decided to embrace this new 'Internet+' era by opening a new online store to reseize the market share, it needs to adopt a new management system containing technologies such as big data and cloud computing which have performed a significant role in this era. At the same time, to keep pace with the new requirements, both physical and online store needed a simple information management system and database to support their inventory and sales operations. This paper aims to set and design the database to support the operations of this industry.

To overcome the network difficulty such as long propagation delay and traffic load imbalance when forwarding data packets through multiple hops in LEO satellite network, we propose an optimal strategy based routing algorithm for LEO satellite network using the cooperative game theory. With the idea of cooperation for mutual benefit, a LEO satellite node has the motivation of improving its own network performance gain by cooperation with neighbors to accomplish the multi-hop forwarding task of data packets. A satellite node compares the benefits of joining various routing coalitions, and tends to choose a more powerful next-hop coalition member node for data packet forwarding, which effectively distributes and balances the traffic load of the popular nodes. Such preference also improves the utilization of the satellite network resources, and reduces the average network delay of data packets. Our simulation results show that compared with the traditional satellite routing algorithms based on the shortest path, the average packet routing delay using the proposed algorithm is reduced by 18.5% and the traffic load balance of the network is increased by 65.6%. By replacing the shortest routing path with a path of satellite nodes with the expected optimal routing performance benefit, the proposed routing algorithm outperforms the existing algorithm on both the temporal and spatial network performance. © Springer Nature Singapore Pte Ltd. 2018.

HCV is a hepatotropic RNA virus recognized for its frequent virulence and fatality worldwide. Despite many vaccine development programs underway, researchers are on a quest for natural bioactive compounds due to their multivalent efficiencies against viral infections, considering which the current research aimed to figure out the target-specificity and therapeutic potentiality of α, β, and δ subunits of amyrin, as novel bioactive components against the HCV influx mechanism. Initially, the novelty of amyrin subunits was conducted from 203 pharmacophores, comparing their in-silico pharmacokinetic and pharmacodynamic profiles. Besides, the best active site of CD81 was determined following the quantum tunneling algorithm. The molecular dynamic simulation was conducted (100 ns) following the molecular docking steps to reveal the parameters- RMSD (Å); Cα; RMSF (Å); MolSA (Å); Rg (nm); PSA (Å); SASA (Å), and the MM-GBSA dG binding scores. Besides, molecular strings of CD81, along with the co-expressed genes, were classified, as responsible for encoding CD81-mediated protein clusters during HCV infection, resulting in the potentiality of amyrins as targeted prophylactics in HCV infection. Finally, in vivo profiling of the oxidative stress marker, liver-specific enzymes, and antioxidant markers was conducted in the DMN-induced mice model, where -amyrin scored the most significant values in all aspects.
