DIETARY CONDITIONS AND DIFFERENTIAL ACCESS TO FOOD RESOURCES AMONG THE VARIOUS CLASSES DURING THE HAN PERIOD
No full textIn this thesis, I study how food resources and dietary conditions were determined by social and economic status during the Han period in China, B.C. 206~A.D.220. Even though earlier scholars have published research concerning the Chinese food culture of this period, these studies were limited in that they only illustrated the dietary culture of the upper class or the available food resources in one geographic area. Also, without any persuasive data, it has been assumed by these earlier scholars that there were big differences in food resources and food consumption between the upper and lower classes. In this thesis, for comparison among the classes, I divide the social and economic classes into five stratified groups: nobles, officials, peasants, soldiers and convicts. After a brief introduction of the nature of each social class, I examine the food resources and nutritional condition of each group using information such as the wealth and income of each group, the market price of food resources, the agricultural products of peasants, and the amount of food distribution to soldiers and convicts. I found these data from archaeological remains, received historical records and pictorial data, and excavated texts. This research shows a broader view of Chinese dietary condition focusing not only on the variety of food resources of nobles, but also on the different food accessibilities among the officials, and the food deficiencies of peasants. It also deals with the situations of food supply for soldiers and convicts in an effort to reveal the true dietary consumption and nutritional conditions for all Chinese. This research proves that the various classes during the Han period in China had different food resources and dietary conditions

Task-Guided Pair Embedding in Heterogeneous Network
No full textMany real-world tasks solved by heterogeneous network embedding methods can be cast as modeling the likelihood of a pairwise relationship between two nodes. For example, the goal of author identification task is to model the likelihood of a paper being written by an author (paper-author pairwise relationship). Existing taskguided embedding methods are node-centric in that they simply measure the similarity between the node embeddings to compute the likelihood of a pairwise relationship between two nodes. However, we claim that for task-guided embeddings, it is crucial to focus on directly modeling the pairwise relationship. In this paper, we propose a novel task-guided pair embedding framework in heterogeneous network, called TaPEm, that directly models the relationship between a pair of nodes that are related to a specific task (e.g., paper-author relationship in author identification). To this end, we 1) propose to learn a pair embedding under the guidance of its associated context path, i.e., a sequence of nodes between the pair, and 2) devise the pair validity classifier to distinguish whether the pair is valid with respect to the specific task at hand. By introducing pair embeddings that capture the semantics behind the pairwise relationships, we are able to learn the fine-grained pairwise relationship between two nodes, which is paramount for task-guided embedding methods. Extensive experiments on author identification task demonstrate that TaPEm outperforms the state-of-the-art methods, especially for authors with few publication records

Diagnosis. The new species is similar externally to S. suffuscalis (Swinhoe, 1886) (Figs 3, 4, 6), but it can be distinguished from the latter by the following characters: forewing with light grey ground color, scattered small dark brown, and with two dark brown costal patches, one narrow patch in basal line region, one broad patch in median line region; crossline more faint; reniform spot slightly oblate; male genitalia with dorsum of ampullae triangular; digitus fingershaped and without setae; phallus slightly incurved at distal 1/5 and pointed at apex; vesica with a sclerotized and coneshaped cornutus. In S. suffuscalis, the forewing ground color is smokey black, scattered small black, and without long patches at costa; crossline is black and distinct; reniform spot is swollen; male genitalia with dorsad of apmpullae bearing thumblike, apically setose process; digitus is triangular and setose at tip; phallus is extremely incurved into a fishhookshaped, and without cornutus. Description. Adult (Figs 1, 2). Wingspan of male 9.5–10.0 mm. Head and thorax light greyish white; abdomen mostly grey, and with canary yellow tufts at terminal part. Forewing light grey, subterminal and terminal lines areas suffused with dark brown; costal margin area with two dark brown patches, one narrow patch in basal line region, one wide triangle patch in median line region; crosslines more faint, except terminal line marked by blackish-brown alternate dots, postmedial line waved, black at anterior half, weakly reddish brown at posterior half; reniform stigma oblate, yellowish white, outlined in fuscous; fringes dark brown. Hindwing lighter than forewing, grey throughout; discal spot small, and indistinct, slightly dark; terminal line grey; base of fringe whitish yellow; outer margin slightly concave at middle, rather straight at anal angle area. Male genitalia. (Fig. 7). Tegumen long and narrow evenly, approximately the same length as the vinculum. Vinculum rather broader than tegumen, V-shaped.

Valva broad and flat, with dorsal and ventral margins parallel for basal 4/5, and gradually narrowed towards ampullae; sacculus wide, thick, gradually narrowed towards, ventral margin with obtuse angle at posterior part, process of sacculus about 1/3 as long as sacculus; ampullae axe-shaped, heavily setose at rounded apex, dorsal process triangular, curved slightly. Digitus short finger-shaped, without setae. Phallus cylindrical basally, widest at 1/3 anterior part; with coiled at middle; distal 1/5 incurved, and gradually sharped towards apex; coecum weakly sclerotized, broad and short cone-shaped, about 1/3 as long as phallus. Vesica membranous, with a strongly sclerotized and cone-shaped cornutus. Distribution. (Fig. 14). Cambodia (Mondul kiri and Kampot). Etymology. The species name “ mondulkiriensis ” refers to the locality of holoype: Prov. Mondul kiri. Bionomics. (Fig. 13). The new species inhabits tropical montane evergreen broad-leaved forest in Cambodia. Remarks. It is based primarily on the male genitalia features that mondulkiriensis is placed in Sternitta.Published as part of Qi, Mujie, Bae, Yangseop & Han, Huilin, 2020, A new species of Sternitta Fibiger, 2011 (Lepidoptera, Erebidae, Hypenodinae Micronoctuini) from Cambodia, pp. 596-600 in Zootaxa 4859 (4) on pages 597-599, DOI: 10.11646/zootaxa.4859.4.7, http://zenodo.org/record/441338

Stability analysis of gradient-based neural networks for optimization problems
No full textThe paper introduces a new approach to analyze the stability of neural network models without using any Lyapunov function. With the new approach, we investigate the stability properties of the general gradient-based neural network model for optimization problems. Our discussion includes both isolated equilibrium points and connected equilibrium sets which could be unbounded. For a general optimization problem, if the objective function is bounded below and its gradient is Lipschitz continuous, we prove that (a) any trajectory of the gradient-based neural network converges to an equilibrium point, and (b) the Lyapunov stability is equivalent to the asymptotical stability in the gradient-based neural networks. For a convex optimization problem, under the same assumptions, we show that any trajectory of gradient-based neural networks will converge to an asymptotically stable equilibrium point of the neural networks. For a general nonlinear objective function, we propose a refined gradient-based neural network, whose trajectory with any arbitrary initial point will converge to an equilibrium point, which satisfies the second order necessary optimality conditions for optimization problems. Promising simulation results of a refined gradient-based neural network on some problems are also reported
