The Impact Of The Knowledge Sharing In Social Media On Consumer Behaviour

In the recent years, there is a significant rise in the usage of social networking site for organizations to organize marketing campaigns. It is necessary for advertisers to structure their information well in order for consumers to accept the message or product information. This study investigated the consumer purchasing process and knowledge flows between individuals in social media, at the same time considering the different type of proximity that affect it. Using the consumer purchasing decision process[1] as a source of credibility, this study will analyze from several research paper to test its hypothesis related to the different types of proximity. Results and theories have shown that advertisement and product information in social media are affected by the different types of proximity plays, which is creating an impact in the consumer purchasing decision process

ZERO TRUST: DISTRIBUTED AND LIGHT-WEIGHT AUTHENTICATION FOR WORMHOLE ATTACKS IN LOW-POWER AND LOSSY NETWORKS

Anomaly detection in a Low-Power and Lossy Network (LLN) is important in light of threats such as a wormhole attack. However, such detection is challenging given node constraints such as, for example, limited power and memory. Techniques are presented herein that address those challenges thus benefiting the stability, reliability, and security of LLNs. The presented techniques include, among other things, a distributed and light-weight authentication method (where identification of a suspicious node is done locally, between two nodes, thus obviating heavy traffic upward to a root node) and a node rating credit rank mechanism (through which, for example, a node may detect whether there is a wormhole attack)

ENHANCING POINT-TO-POINT PERFORMANCE IN LOW-POWER AND LOSSY NETWORKS BASED ON GROUP AD HOC ON-DEMAND DISTANCE VECTOR AND PROJECTED DESTINATION ADVERTISEMENT OBJECT

Techniques are described herein for enhancing the performance of Point-to-Point (P2P) performance in Low-power and Lossy Networks (LLNs) based on Ad-hoc On-demand Distance Vector (AODV) and Projected Destination Advertisement Object (P-DAO). These techniques may restrict the flooding range of AODV and reduce the computational complexity of P-DAO

NON-ORTHOGONAL MULTIPLE ACCESS FOR COLLISION AVOIDANCE IN LOW-POWER AND LOSSY NETWORKS

Techniques are described herein for a Non-Orthogonal Multiple Access (NOMA) mechanism to improve network throughput due to multiplexing gain in the power domain. Several received Signal-to-Noise Ratio (SNR) levels may be set to achieve multiple access of nodes depending on different network requirements. In particular, these techniques may prevent hidden node collision by assigning different received SNR levels between the upward link and the downward link

Progress in the diagnosis of lymph node metastasis in rectal cancer: a review

Historically, the chief focus of lymph node metastasis research has been molecular and clinical studies of a few essential pathways and genes. Recent years have seen a rapid accumulation of massive omics and imaging data catalyzed by the rapid development of advanced technologies. This rapid increase in data has driven improvements in the accuracy of diagnosis of lymph node metastasis, and its analysis further demands new methods and the opportunity to provide novel insights for basic research. In fact, the combination of omics data, imaging data, clinical medicine, and diagnostic methods has led to notable advances in our basic understanding and transformation of lymph node metastases in rectal cancer. Higher levels of integration will require a concerted effort among data scientists and clinicians. Herein, we review the current state and future challenges to advance the diagnosis of lymph node metastases in rectal cancer

Study on thermal-hydraulic characteristics of novel channels for printed circuit heat exchanger using supercritical CO2

© 2023 The American Society of Mechanical Engineers. All rights reserved. This is the accepted manuscript version of an article which has been published in final form at https://doi.org/10.1115/1.4062998Two new types of PCHE channels are proposed based on the typical airfoil fin PCHE channel proposed in literatures (standard channel) to further improve the thermal-hydraulic performances of airfoil fin PCHE channel. The small shuttle fins and oval fins are employed between the adjacent two airfoil fins of two novel channels, respectively. Using supercritical CO2 as the working fluid, the thermal-hydraulic performances and enhancement mechanisms of the novel channels are numerically investigated. The results show that the channel with shuttle fins has the best comprehensive performance. The Nusselt number of the channel with shuttle fins is 6.7–26% larger, and the f factor is 8.3–18.6% larger than that of the standard channel under the selected conditions, which leads to a 3–19.1% increase in the PEC (comprehensive performance evaluation criteria). The Nusselt number of the channel with oval fins is 9–27.3% larger, and the f factor is 26.6–43.4% larger than that of the standard channel, which leads to a 1–15.3% increase in the PEC. The applications of small fins between the adjacent two fins can effectively reduce the low-velocity region area and enhance the local disturbance, thereby effectively improving the thermal-hydraulic performance. The enhancement mechanism of the novel fin PCHE channel structure can be well explained by the principle of field synergy. It can be found that the synergies of the temperature gradient field and the velocity field in two novel channels are significantly improved.Peer reviewe

Research on the Status Quo and Satisfaction of ' Internet + ' Home Care Model in Hangzhou in the Post-Epidemic Era

This paper takes Hangzhou as an example to study the current situation of the "Internet +" home care model in Hangzhou in the post-epidemic era and the satisfaction of citizens with this new pension model. We established a structural equation model of citizens' satisfaction with the "Internet +" home care model, and calculated the satisfaction index by combining the CSI satisfaction index
