Design of L+Band Bismuth-doped Fiber Laser

At present, the development of new communication bands to meet the needs of large communication transmission capacity in the current era is one of the key research topics. The conventional erbium-doped laser is limited by its structure which has the problem of short luminous bandwidth and can not cover a large communication band. Therefore, there is growing interest in designing bismuth-doped glass and fiber with ultra-wide gain bandwidth for fiber laser applications. By utilizing its ultra-wide gain bandwidth characteristics, important communication devices such as broadband fiber amplifiers and broadband tunable fiber lasers can be designed to operate in the L+band, thereby solving the problem that the ultra-wide bandwidth of the optical communication window cannot be achieved in the future high-speed communication systems. In this study, the 1550nm pump source is used to excite the bismuth-doped fiber, and the MATLAB numerical simulation modeling is used to design a bismuth-doped fiber laser with a central wavelength of 1650nm and a threshold power of 10W. To a certain extent, this design addresses the research gap in L+ band bismuth-doped fiber lasers.

Assessing phenotypic variation and plasticity of endemic gastropods from thermal water refugia using complex morphometric techniques: A case study of Lake Pețea melanopsids.

Understanding the underlying reasons for phenotypic plasticity and resulting morphological disparity is one of the key topics of evolutionary research. The phenotypic plasticity of extant and fossil melanopsids has been widely documented. Yet millennial-resolution, well-dated records from small aquatic habitats harboring endemics are scarce. The thermal spring-fed Lake Pețea is an ice age refugia harboring a unique endemic warm-water fauna. Subfossil melanopsids display incredible morphological variability from smooth to keeled, elongated to ribbed, shouldered forms. Numerous morphotypes have been considered as individual taxa with a fluent succession from the smooth elongated to the ribbed, shouldered types. This study presents an extensive morphometric analysis of subfossil melanopsids (ca. 3500 specimens) derived from stratified samples with an independent chronology. The aim was to separate morphotypes for investigations of temporal morphological disparity. Our results challenge the widely accepted hypothesis that proposes the evolution of shouldered, compressed, ribbed shells through a two-step process from smooth elongated spindle-shaped shells. Instead, it suggests that the subfossil shells belong to two distinct taxa present throughout the available stratigraphic data. The main components of shape variation, shape globularity, and shell coiling seem allometry-related. Ribs, striation, and keels appear randomly. High-spired spindle-shaped forms were considered to represent specimens of Microcolpia daudebartii hazayi. Bulkier low-spired and shouldered specimens represent phenotypes of Mi. parreyssii parreyssii. The collective and random distribution of morphotypes from the early stages of the lake's history also refutes the idea of a continuous transformation of the elongated forms into compressed, shouldered ones. Rather points to multiple events and environmental stimuli triggering development. Melanopsids appear in Late Glacial horizons, with Theodoxus prevostianus preferring temperatures above 23°C which may indicate the subordinate presence of hot water microhabitats in cooler waters.

The role of salt basins in the race to net zero: a focus on Australian basins and key research topics

Globally, many salt basins host highly productive fossil fuel resources and provide excellent opportunities for developing economically viable clean energy systems such as (1) energy storage in salt caverns, including hydrogen, helium, natural gas, and other economic gases; (2) permanent sequestration of carbon dioxide; (3) development of geothermal energy; (4) critical mineral exploration and extraction, and (5) natural hydrogen production. Despite the high potential to deploy financially viable clean energy solutions related to the formation and evolution of salt basins, our current knowledge regarding critical aspects of salt basin characterisation in Australia is limited. New research is necessary to develop these sustainable energy systems and achieve net zero emissions; therefore, it is critical to re-evaluate the geology of salt basins. Key research areas to enable these opportunities relate to the precipitation, deposition, and deformation of salt basins. This paper reviews the potential for a range of energy systems within salt basins, outlines emerging research topics, and demonstrates the value of Australian salt basin outcrop analogues for improved subsurface interpretation globally.

Impact of the Development of a Low-Carbon Economy on Global International Trade

With the continuous development of human society, the high intensity of energy use has caused serious damage to the environment. Due to the aggravation of ecological problems, governments have gradually set their eyes on balancing economic development and environmental protection. In this context, the "low-carbon economy" emerged and became the keyword in the new policies introduced by governments around the world. However, along with the introduction of low-carbon policies in various countries, its significant impact on international trade has also begun to emerge. Due to the different national conditions and backgrounds of various countries, how to develop a low-carbon economy and how to develop international trade under the background of a low-carbon economy has become one of the key research topics of all countries in the world. By discussing the development of a low-carbon economy and its relationship with international trade, a feasible new strategy of international trade development under the background of low low-carbon economy is proposed.

Progress and landscape of disaster science: Insights from computational analyses

This study identifies trends in disaster science research as well as knowledge gaps at a broad scale in order to help underpin and inform future research in the area. A numerical analysis of 58,106 peer-reviewed articles over four decades reveals key research themes and clusters, their temporal variation of activity as well as the influential studies that have played a key role in their development. Results indicate that what we recognize as contemporary disaster science has only shown discernible patterns of activity and knowledge foundation formation since the 1990s. Disaster research currently constitutes approximately 0.23 % of all academic papers published per year. The initial and intermediate phases of the development of the field have been unsystematic and fragmented, with the focus of the field fluctuating for almost two decades until recently when research clusters have shown signs of stabilizing. It is observable that, over the last few years, more attention has been allocated to mitigation, response and recovery by focusing on issues such as the psychological impacts of disasters, reducing exposure to disasters and building community resilience to cope and recover from disasters. This is in contrast with earlier years where the focus was predominantly on preparedness and prevention. Research in different countries has been highly correlated with the types of disasters that occur in their regions, highlighting the relevance of the local situatedness and context in disaster research. The recent emergence and explosive growth of a research cluster linked to flood detection, mapping and hazard assessment is particularly notable, marking the sharpest growth of a single research cluster ever recorded in this field. A similar trend, though of a smaller magnitude, is observable in relation to research on wildfire hazard. Overall, flood-related research has proven one of the dominant themes, with multiple clusters detectable on the topic, each with their own distinguishable knowledge foundation (i.e., set of references). The pattern of collaboration among disaster researchers is shifting from predominantly domestic research towards international collaborations (currently reaching about 1/3 of all disaster-related papers each year), a sign of recognition to the value of cross-cultural and interdisciplinary perspectives in disaster research.

Current trends in the role of neuroinflammation & α-synuclein in alcohol use disorder: A systematic quantitative literature review.

The neurodegenerative effects alcohol use disorder (AUD) have been well characterized and are likely due to the long-term effects of alcohol on the brain. The molecular events that underlie regional neuronal loss are a focus of current research. Chronic inflammation in the central nervous system, termed neuroinflammation, contributes to the progressive loss of neurons in the brain. Using data from genome-wide association studies and genetic and gene expression data, α-synuclein was identified as a gene of interest for AUD almost 10 years ago. Despite this and the well-recognized role of α-synuclein in mediating neuroinflammation in other neurodegenerative diseases, its role in alcohol-induced brain damage and AUD is yet to be elucidated. This systematic literature review quantifies and analyzes relationships between AUD, α-synuclein, and neuroinflammation. The review identified fewer studies focused on the role in AUD of α-synuclein (30) than on neuroinflammation (177), with published studies heavily centered on the myeloid differentiation primary response 88 (MyD88)-dependent toll-like receptor 4 (TLR4) pathway. The systematic review revealed that no original literature investigates the roles of α-synuclein and neuroinflammation in AUD and that there are significantly fewer published articles on the role of α-synuclein in AUD than in other neuroinflammatory conditions. Studies of the role of neuroinflammation in AUD are largely centered on the TLR4 signaling cascade, followed by TLR2 and TLR3, and soluble cytokines such as IL-10, IL-1β, and TNF-α. Key research themes identified in other neurodegenerative disorders provide new insights for further investigation in AUD.

Can Urban Air Mobility become reality? Opportunities and challenges of UAM as innovative mode of transport and DLR contribution to ongoing research

AbstractUrban Air Mobility (UAM) is a new air transportation system for passengers and cargo in urban environments, enabled by new technologies and integrated into multimodal transportation systems. The vision of UAM comprises the mass use in urban and suburban environments, complementing existing transportation systems and contributing to the decarbonization of the transport sector. Initial attempts to create a market for urban air transportation in the last century failed due to lack of profitability and community acceptance. Technological advances in numerous fields over the past few decades have led to a renewed interest in urban air transportation. UAM is expected to benefit users and to also have a positive impact on the economy by creating new markets and employment opportunities for manufacturing and operation of UAM vehicles and the construction of related ground infrastructure. However, there are also concerns about noise, safety and security, privacy and environmental impacts. Therefore, the UAM system needs to be designed carefully to become safe, affordable, accessible, environmentally friendly, economically viable and thus sustainable. This paper provides an overview of selected key research topics related to UAM and how the German Aerospace Center (DLR) contributed to this research in the project "HorizonUAM - Urban Air Mobility Research at the German Aerospace Center (DLR)". Selected research results on the topics of market potential and public acceptance, vehicle design (including battery degradation, onboard systems, cabin design, cabin simulation), infrastructure, operations (including U-space, safe autonomy, navigation, communication, cost modeling) and overall system modeling are briefly presented.

Identifying Research Priorities in Limb Reconstruction Surgery in the United Kingdom.

Limb reconstruction surgery (LRS) has a wide range of clinical applications within orthopaedic and trauma surgery. We sought a consensus view from limb reconstruction healthcare practitioners across the United Kingdom to help guide research priorities within LRS. Our aim is to guide future clinical research in LRS, and assist healthcare practitioners, clinical academics, and funding bodies in identifying key research priorities to improve patient care. A modified Delphi approach was used; it involved an initial scoping survey and a 2-round Delphi process to identify the consensus research priorities in both adult and paediatric LRS. Participants were asked to rank approved submitted questions according to perceived importance on a 5-point Likert scale, where 1 represented lowest importance and 5 indicated highest importance. Mean scores were calculated to identify a consensus of the top ten research priorities for adult and paediatric LRS. One hundred and fifteen participants primarily from across the United Kingdom working in LRS contributed to the modified Delphi process. Participants ranked and then re-ranked the presented research topics in terms of perceived importance. This led to the identification of a top ten research priorities in both adult and paediatric LRS, respectively, based on the collective responses of LRS practitioners. The highest-ranked questions in both adult and paediatric practice related to how to best assess and record patient-reported outcome measures (PROMs) in LRS patients. Other priorities included the effectiveness of specialist physiotherapy, the use of patient-focused psychological support, and the use of various operative management strategies for infection and limb length discrepancies. We present a consensus-driven research priority study that outlines the key research topics and themes determined by healthcare professionals within LRS in the United Kingdom. These questions will assist funding bodies in prioritising where research funding may be best utilised and help drive future improvement in patient care.

Journal of International Accounting Research: A Bibliometric Analysis

ABSTRACT This study utilizes bibliometric analysis to examine the research published by the Journal of International Accounting Research (JIAR). JIAR was established in 2002 to disseminate high-quality accounting research that emphasizes international relevance and implications. First, we perform publication and citation analyses to identify the leading articles, authors, institutions, and geographic affiliations. Although U.S.-based authors account for most publications, authorship from Asia, Australia, and Europe is expanding. Second, based on thematic structure analyses, we identify nine key research themes among JIAR publications. Although studies relevant to international accounting remain the mainstay of the journal’s publications, other themes like corporate governance, auditing, and corporate social responsibility are growing. Our findings of successful diversification in authorship and topic areas over time attest to the contributions of past and present JIAR editorial teams in strengthening the research in international accounting and promoting accounting research internationally.

Knowledge framework of intravenous immunoglobulin resistance in the field of Kawasakidisease: A bibliometric analysis (1997-2023).

Kawasaki disease (KD) is an autoimmune disease with cardiovascular disease as its main complication, mainly affecting children under 5 years old. KD treatment has made tremendous progress in recent years, but intravenous immunoglobulin (IVIG) resistance remains a major dilemma. Bibliometric analysis had not been used previously to summarize and analyze publications related to IVIG resistance in KD. This study aimed to provide an overview of the knowledge framework and research hotspots in this field through bibliometrics, and provide references for future basic and clinical research. Through bibliometric analysis of relevant literature published on the Web of Science Core Collection (WoSCC) database between 1997 and 2023, we investigated the cooccurrence and collaboration relationships among countries, institutions, journals, and authors and summarized key research topics and hotspots. Following screening, a total of 364 publications were downloaded, comprising 328 articles and 36 reviews. The number of articles on IVIG resistance increased year on year and the top three most productive countries were China, Japan, and the United States. Frontiers in Pediatrics had the most published articles, and theJournal of Pediatricshad the most citations. IVIG resistance had been studied by 1889 authors, of whom Kuo Ho Chang had published the most papers. Research in the field was focused on risk factors, therapy (atorvastatin, tumor necrosis factor-alpha inhibitors), pathogenesis (gene expression), and similar diseases (multisystem inflammatory syndrome in children, MIS-C). "Treatment," "risk factor," and "prediction" were important keywords, providing a valuable reference for scholars studying this field. We suggest that, in the future, more active international collaborations are carried out to study the pathogenesis of IVIG insensitivity, using high-throughput sequencing technology. We also recommend that machine learning techniques are applied to explore the predictive variables of IVIG resistance.

An Exploration of Rural Elderly Care Models under the Rural Revitalization Strategy: A Case Study of Ningxia

With the deepening of aging, elderly care has become a focus of attention in various countries. China is also facing a serious aging issue, and how to reasonably solve the elderly care problems has become one of the key research topics for Chinese experts and scholars. China has vast territory with significant regional disparities between the east and west, leading to unbalanced urban and rural development. The aging issue in western rural areas is more severe, yet their development is relatively lagging behind, with serious population loss challenging traditional family care models. Addressing the elderly care problem requires targeted measures based on practical considerations. Taking Ningxia as a case study, this paper finds that the material living standards of elderly rural residents in Ningxia are low, and their spiritual life is relatively lacking. By analyzing the deficiencies in rural elderly care in Ningxia from the perspectives of family care and institutional care, corresponding solutions are proposed. Currently, rural family care in Ningxia faces difficulties, institutional care development is immature, and public acceptance is low. Therefore, suggestions are made to improve rural infrastructure to retain labor, enhance the operation and internal environment of care institutions, and increase public acceptance, aiming to improve the living conditions of elderly rural residents in Ningxia and meet their care needs.

Prediction of Changes in the Exchange Rate between the USD and the CNY and Analysis of Influencing Factors

As one of the important indicators of the global financial market, the fluctuation of the US dollar to Chinese yuan exchange rate not only directly affects the economic development of China and the United States, but also has important significance for analyzing the global economic situation. Analyzing the factors influencing the exchange rate between the United States dollar (USD) and the Chinese yuan (CNY) is one of the key research topics today. Researchers have found that exchange rates are influenced by factors such as national policies and the global political situation. However, there is still a certain gap in the comprehensive and objective analysis of these influencing factors. Therefore, the research topic of this article is to predict the trend of the exchange rate between the USD and the CNY and analyze the influencing factors. This study collected exchange rate data from January 2000 to November 2023 and used the ARIMA model to predict exchange rate changes. This study explores the trend of exchange rate changes by visualizing these data. Research has found that significant changes in exchange rates over the past two decades have also occurred during times of global instability and policy adjustments. The economic development level of China and the United States also directly affects the changes in exchange rates. In addition, the model used in this study also predicted the exchange rate between the USD and the CNY in 2024, providing a scientific direction for predicting the economic development trend in 2024.

The Past, Present, and Future of Research on Mathematical Giftedness: A Bibliometric Analysis

There is a well-established historical background of research on mathematical giftedness that can be traced back to the early 1900s. An overarching purpose of this research was to review and explore the existing research and its evolution since its emergence in educational and psychological studies. Thus, we examined the past, present, and future of research on mathematical giftedness using a bibliometric analysis. Our findings provided extensive insights into the intellectual structure of the extant literature on mathematical giftedness, including the leading journals, articles, countries, authors, institutions, and networks among researchers as well as key research topics that were investigated in the literature. Perhaps one of the most striking findings of this study was about the productivity in the field over the years as the bibliometric analysis indicated a decline in the number of publications that were published in the last several years. We discussed possible factors behind the recession in research investigations on mathematical giftedness and provided significant implications of the findings to inform future research.
