Localized and complete resonance in plasmonic structures

This paper studies a possible connection between the way the time averaged electromagnetic power dissipated into heat blows up and the anomalous localized resonance in plasmonic structures. We show that there is a setting in which the localized resonance takes place whenever the resonance does and moreover, the power is always bounded and might go to $0$. We also provide another setting in which the resonance is complete and the power goes to infinity whenever resonance occurs; as a consequence of this fact there is no localized resonance. This work is motivated from recent works on cloaking via anomalous localized resonance

Degradation of organics from laundry water by photoelectrochemical and electrochemical processes on α-Fe2O3 nanostructure

In this study, organics from laundry water, and sodium dodecyl sulfate were degraded by electrochemical (EC) and photoelectrochemical (PEC) processes on aFe203 nanostructure. The applied voltage was between 1 and 3 V. The experimental data were also well simulated by the proposed kinetic models. The results present an economical and environmentally friendly method for developing countries where centralized wastewater facilities are not available

IMPACT OF EXTERNAL DEBT ON FINANCIAL DEVELOPMENT: AN EMPIRICAL ANALYSIS OF SELECTED EAST ASIAN AND PACIFIC COUNTRIES

This article explores the impact of external debt on financial development in a group of fifteen selected East Asian and Pacific countries from 1992 to 2021. These countries include Cambodia, China, Fiji, Indonesia, Lao PDR, Mongolia, Myanmar, Papua New Guinea, the Philippines, Samoa, the Solomon Islands, Thailand, Tonga, Vanuatu, and Vietnam. Data were extracted from the World Bank and International Monetary Fund databases. This study employs random effects and fixed effects models, Driscoll-Kraay standard errors, and the generalized method of moments to test two hypotheses. The results indicate that external debt has a positive impact on the financial development of these East Asian and Pacific countries, where economic growth plays a vital role in promoting financial development. Additionally, a nonlinear impact of external debt on the financial development of these East Asian and Pacific countries is observed. Based on these findings, it is recommended that appropriate financial development policies be implemented in the identified countries

Performance analysis with wireless power transfer constraint policies in full-duplex relaying networks

In practice, full-duplex (FD) transmission mode not only helps extend the coverage but also lengthen network lifetime. In this paper, we develop wireless power supply policies, namely separated power (SP) and harvested power (HP) to propose a flexible architecture at the relay node in FD decode-and-forward (DF) relaying networks considering time switching-based relaying protocol (TSR) to achieve optimal time used for a communication process. This transmission mode requires more processing procedure at the relay, i.e. antenna installations and radio frequency (RF) self-interference cancellation. We evaluate the optimal power constraints in case of SP and HP to achieve better power consumption efficiency at the relay node. More importantly, closed-form expressions for outage probability and throughput are provided, and we also use numerical and simulation results to compare SP with HP.Web of Science234767

Constructing a Knowledge Graph for Vietnamese Legal Cases with Heterogeneous Graphs

This paper presents a knowledge graph construction method for legal case documents and related laws, aiming to organize legal information efficiently and enhance various downstream tasks. Our approach consists of three main steps: data crawling, information extraction, and knowledge graph deployment. First, the data crawler collects a large corpus of legal case documents and related laws from various sources, providing a rich database for further processing. Next, the information extraction step employs natural language processing techniques to extract entities such as courts, cases, domains, and laws, as well as their relationships from the unstructured text. Finally, the knowledge graph is deployed, connecting these entities based on their extracted relationships, creating a heterogeneous graph that effectively represents legal information and caters to users such as lawyers, judges, and scholars. The established baseline model leverages unsupervised learning methods, and by incorporating the knowledge graph, it demonstrates the ability to identify relevant laws for a given legal case. This approach opens up opportunities for various applications in the legal domain, such as legal case analysis, legal recommendation, and decision support.Comment: ISAILD@KSE 202
