From Primitive “Imagery” (Yi-Xiang) to the Humanistic Concepts of “Inspiring Imagery” (Xing-Xiang) and “Entrusting One’s Thoughts and Feelings to Imagery”(Ji-Xiang): The Depiction of Plants in Chinese Literary History

In Western civilization,as exemplified by ancient Greece,the primitive imagery of plants ceased to appear in daily life.Nevertheless,in China,the primitive imagery of plants that originated and flourished in primitive times never ceased to prevail even after entering the civilized era.Merged with rationality,it gave rise to the humanistic concepts of“inspiring imagery”(xing-xiang)and“entrusting one’s thoughts and feelings to imagery”(ji-xiang),as represented by the depiction of plants in works like The Book of Odes and Odes of Chu.This was due to China’s unique civilization origin and early civilization development pattern.According to the concepts of“inspiring imagery”and“entrusting one’s thoughts and feelings to imagery”that emerged in the civilized and rational era,individual emotions and independent personalities can inspire or be entrusted to imagery,while imagery represents the racial collective consciousness rooted in the long-standing tradition and imbued with religious,ethical,and political connotations in the context of kinship-based governance.As typical artistic expressions formed during China’s Axial Age,“inspiring imagery”and“entrusting one’s thoughts and feelings to imagery”related to the depiction of plants have significantly contributed to shaping China’s distinctive aesthetic preferences,nourishing literary and artistic creations spanning over two millennia since the Qin and Han dynasties,and forging the cultural and psychological structures of the Chinese nation.

Adaptive Network Sustainability and Defense Based on Artificial Bees Colony Optimization Algorithm for Nature Inspired Cyber Security

Cyber Defense is becoming a major issue for every organization to keep business continuity intact.The presented paper explores the effectiveness of a meta-heuristic optimization algorithm-Artificial Bees Colony Algorithm(ABC)as an Nature Inspired Cyber Security mechanism to achieve adaptive defense.It experiments on the Denial-Of-Service attack scenarios which involves limiting the traffic flow for each node.Businesses today have adapted their service distribution models to include the use of the Internet,allowing them to effectively manage and interact with their customer data.This shift has created an increased reliance on online services to store vast amounts of confidential customer data,meaning any disruption or outage of these services could be disastrous for the business,leaving them without the knowledge to serve their customers.Adversaries can exploit such an event to gain unauthorized access to the confidential data of the customers.The proposed algorithm utilizes an Adaptive Defense approach to continuously select nodes that could present characteristics of a probable malicious entity.For any changes in network parameters,the cluster of nodes is selected in the prepared solution set as a probable malicious node and the traffic rate with the ratio of packet delivery is managed with respect to the properties of normal nodes to deliver a disaster recovery plan for potential businesses.

Inter-Fraction Analysis of One Week Hypo-Fractionation of Deep Inspiration Breath Hold (DIBH) Technique for Left Sided Breast Cancer Radiation Treatment

The aim of this study was to investigate the inter-fraction variations, patient comfort and knowledge at Charlotte Maxeke Johannesburg Academic Hospital (CMJAH). The differences in set-up that occurred between treatment sessions for the left sided breast patients were observed and recorded. Measurements of routine set-up variation for 24 patients were performed by matching the cone beam computed tomography (CBCT) and the planning computed tomography (CT). Scans of all five fractions per patient were used to quantify the setup variations with standard deviation (SD) in all the three directions (anterior posterior, left right, and superior inferior). The patients DIBH comfort and knowledge was also evaluated. The average translational errors for the anterior posterior (AP, z), left-right (LR, x), and Superior-inferior (SI, y) directions were 0.40 cm, 0.40 cm, and 0.40 cm, respectively. The translation variation of the three directions showed statistical significance (P < 0.05). On comfort and knowledge investigation, among all participants, 80% moderately agreed that the therapist’s instructions for operating the deep inspiration breath hold (DIBH) technique were easy to understand, and 63.33% indicated that their comfort with the DIBH technique was neutral or average. The inter-fraction variations in patients with left-sided breast cancer were qualitatively analyzed. Significant shifts between CBCT and planning CT images were observed. The daily treatment verification could assist accurate dose delivery.
