Abstract

Hardware-based spiking neural networks (SNNs) are regarded as promising candidates for the cognitive computing system due to low power consumption and highly parallel operation. In this work, we train the SNN in which the firing time carries information using temporal backpropagation. The temporally encoded SNN with 512 hidden neurons showed an accuracy of 96.90% for the MNIST test set. Furthermore, the effect of the device variation on the accuracy in temporally encoded SNN is investigated and compared with that of the rate-encoded network. In a hardware configuration of our SNN, NOR-type analog memory having an asymmetric floating gate is used as a synaptic device. In addition, we propose a neuron circuit including a refractory period generator for temporally encoded SNN. The performance of the 2-layer neural network consisting of synapses and proposed neurons is evaluated through circuit simulation using SPICE. The network with 128 hidden neurons showed an accuracy of 94.9%, a 0.1% reduction compared to that of the system simulation of the MNIST dataset. Finally, the latency and power consumption of each block constituting the temporal network is analyzed and compared with those of the rate-encoded network depending on the total time step. Assuming that the total time step number of the network is 256, the temporal network consumes 15.12 times lower power than the rate-encoded network and can make decisions 5.68 times faster.

33. Origin of New Broad Raman D and G Peaks in Annealed Graphene

Abstract

Since graphene, a single sheet of graphite, has all of its carbon atoms on the surface, its property is very sensitive to materials contacting the surface. Herein, we report novel Raman peaks ob-served in annealed graphene and elucidate their chemical origins by Raman spectroscopy and atomic force microscopy (AFM). Graphene annealed in oxygen-free atmosphere revealed very broad additional Raman peaks overlapping the D, G and 2D peaks of graphene itself. Based on the topographic confirmation by AFM, the new Raman peaks were attributed to amorphous carbon formed on the surface of graphene by carbonization of environmental hydrocarbons. While the carbonaceous layers were formed for a wide range of annealing temperature and time, they could be effectively removed by prolonged annealing in vacuum. This study underlines that spectral features of graphene and presumably other 2-dimensional ma-terials are highly vulnerable to interference by foreign materials of molecular thickness., Comment: 15 pages, 3 figures

39. Three essays on corporate governance in Korea

Author

Abstract

This thesis analyzes three topics regarding Korean firms’ corporate governance. The first chapter examines whether organized employees play a role in limiting executive compensation. Considering that employees’ voices and power are best represented by labor unions and unionization rates, I conclude that labor union existence and rates are both negatively associated with cash compensation. I also find that such negative association is progressively stronger for upper percentile executive pay. I show that the existence of labor unions has a strong negative correlation with stock option use as well, but that the union rate does not. This implies that, if a firm has an organized union, it may become more difficult for that firm to introduce a new payment method such as an executive stock option. The second chapter tests owner-managed firms’ demand for the Directors’ and officers’ liability insurance (D&O insurance). D&O insurance covers the litigation costs that have to be paid by the directors and officers in case they are sued by other stakeholders. Because D&O insurance premium is paid by the corporation (shareholders), not by directors and officers, even though it primarily protects these people, the agency cost related benefits that shareholders could draw from this insurance were frequently discussed in previous studies. In this chapter, I hypothesize that, because such functions of D&O insurance are less useful in case there are few interest conflicts, firms that rarely suffer from agency issues should demand the insurance less. I focus on owner-manager firms as examples of where there is little agency issue and test the hypothesis. I show that both the probability of purchase and the size of insurance coverage are lower in owner-managed firms. The price of insurance was also lower in owner-manager firms, implying that owner-managership signals lower litigation risks. The third chapter seeks to answer the fundamental question in insurance research: Does corporate risk increase corporate insurance demand? I run a natural experiment using a legislative change which increases litigation risk as an exogenous shock, and provide empirical evidence that firms increase insurance demand when they are exposed to increased risks. The Korean Government has decided to adopt shareholder class action law for public firms with assets over a certain threshold. With shareholder class action, even small shareholders can raise litigation against a board of directors, executives, or a firm itself, so increasing the firm’s litigation risk. In a differences-in-differences model, I find that the firms that are subject to the law increase the insurance demand significantly more during the period than the firms that are free from class action law.
