La sostenibilidad de los desequilibrios en las balanzas por cuenta corriente de la eurozona
Authors: Frías Pinedo Isidro , Díaz Vázquez María del Rosario , Iglesias Casal Ana
Published: January 2024

En este trabajo estudiamos los factores que determinan la sostenibilidad de los déficits por cuenta corriente en la eurozona y su vinculación con la crisis. Para ello, estimamos las ecuaciones de comercio exterior, donde se confirma el papel determinante de la elasticidad-renta, y, posteriormente, estimamos el crecimiento económico restringido por la balanza de pagos (Thirlwall) para compararlo con el crecimiento efectivo de cada país. Únicamente España, Gre-cia y Portugal mantuvieron, entre 2000 y 2007, crecimientos superiores a los consistentes con la restricción exterior. Aunque no sostenibles, sus déficits son diferentes ya que tienen raíz estructural en Grecia y Portugal.

Comercio internacional, materias primas y enfermedad holandesa: estudio comparativo de Noruega y Chile
Authors: Sánchez Díez Angeles , García de la Cruz José Manuel , Del Sur Ana
Published: January 2024

En los últimos años, el importante crecimiento de los precios de las materias primas ha despertado nuevamente el interés de la relación entre los ingresos por exportación de materias primas y sus efectos sobre el crecimiento económico. Si bien tradicionalmente esta relación se ha considerado positiva, ya que, en definitiva, revaloriza las ventajas de la especialización, el súbito incremento de recursos externos también ha sido objeto de análisis por sus potenciales efectos negativos sobre la competitividad y la industrialización de las economías. Este fenómeno es conocido como “enfermedad holandesa”, desencadenándose si un incremento de los ingresos por exportación de un recurso natural produce una apreciación del tipo de cambio de la divisa nacional, lo que, a su vez, origina un incremento del precio relativo del resto de bienes comercializables en el mercado internacional, deteriorando su competitividad y, en última instancia, llegando a deprimir su actividad económica.  En este artículo se estudiarán los casos de Noruega y Chile.
Sobre el concepto de economía social y solidaria: aproximaciones desde Europa y América Latina
Authors: Pérez de Mendiguren Castresana Juan Carlos , Etxezarreta Etxarri Enekoitz
Published: January 2024

El término Economía Social y Solidaria, como amalgama de los conceptos Economía Social y Economía Solidaria, se está consolidando como una referencia en los debates sobre la posibilidad de construir otras formas de entender lo económico y otras formas de ser y hacer empresa. Parece claro que con esta idea se pretende reunir en un único término el potencial de cambio,transformación e innovación que se encierra en cada uno de los conceptos anteriores. Sin embargo, y más allá de las referencias compartidas y los consensos aparentes, este artículo reflexiona sobre el paisaje teórico y empírico al que nos aboca el uso cada vez más extendido de este concepto híbrido.
DEL CONCEPTO DE CRECIMIENTO ECONÓMICO AL DE DESARROLLO Y BIENESTAR DE LAS NACIONES: UNA APLICACIÓN A LA UNIÓN EUROPEA
Authors: Sanchez Fernandez Patricio , Prada Blanco Albino

En este trabajo se revisan los atributos y variables que caracterizan el desarrollo y bienestar social en países de elevado nivel de riqueza (UE27). Se analiza larelación entre su posición en términos de riqueza material y la derivada dedistintas estimaciones de índices sintéticos de desarrollo social (IDS). Para ello se utilizan, en primer lugar, los indicadores estimados por el PNUD. A continuación recurrimos a estimadores complementarios mediante la propiametodología PNUD y métodos estadísticos multivariantes y de distancias (análisis factorial y distancia P2). Nuestra conclusión principal es que el nivel de PIB per cápita y el de desarrollo social se muestran desacoplados, lo que justifica y motiva una revisión de los instrumentos dominantes a la hora deevaluar y comparar en el tiempo y el espacio los niveles de bienestar económico.
Factores explicativos de la creación de empresas en Europa: una propuesta desde la perspectiva institucional
Authors: Morales Urrutia Diana , Rodil Marzábal Óscar
Published: January 2024

El fenómeno de la creación de empresas ha alcanzado un interés creciente tanto en el ámbito económico y social como a nivel académico y científico, constituyendo la base material del crecimiento y del empleo. La Nueva Teoría Económica Institucional proporciona un marco apropiado para el estudio de dicho fenómeno, al considerar el papel que desempeñan las instituciones en general (formales e informales) en la decisión efectiva de crear una empresa. En este trabajo se analiza la creación de empresas para el caso de diez países de la Unión Europea en el período 2000-2010, realizando una aproximación cualitativa y cuantitativa al papel de diversos factores institucionales (acceso al crédito, demanda doméstica, programas de gobierno, barreras de mercado, duración del procedimiento, libertad de corrupción).

La eficacia de la política monetaria durante la crisis económica mundial
Authors: Borrallo Egea Fructuoso Alberto , Hierro Recio Luis Ángel
Published: January 2024

El presente trabajo resume las aportaciones referidas a la eficacia de las medidas de política monetaria adoptadas por la Reserva Federal-FED, el Banco Central Europeo-ECB, el Banco de Japón-BoJ y el Banco de Inglaterra-BoE durante la crisis económica y financiera. Las principales conclusiones que obtenemos de la revisión de la literatura son que las medidas de liquidez habrían sido eficaces para reducir los tipos de los mercados interbancarios en una cuantía importante aunque no para mejorar los tipos del crédito y que las de compra de activos habrían sido eficaces para reducir la rentabilidad de la deuda soberana, aunque en este caso con unos efectos más reducidos, y para incidir positivamente en el crecimiento económico y el empleo en USA y Gran Bretaña.
BALANCE OF PAYMEMTS CONSTRAINT IN ARGENTINE ECONOMIC DEVELOPMENT. A NEW ECONOMIC CYCLE DRIVEN BY COMMODITIES?
Authors: Matesanz David , Presno Casquero María José
Published: January 2024

This paper analyses the balance of payments constraint in the Argentine economy in the period 2002-2011. Cointegration techniques are employed to estimate Thirlwall´s (1979) model. We analyse the roles of both the total and commodities exports. Therefore, the aim of the paper is to analyse the Argentine external vulnerability during the post-Convertibility period when commodity prices played an important role in accelerating Argentine exports. The results show that the external restriction to growth from the balance of payments position has relaxed, permitting high economic growth rates since 2002, with commodities playing a central role in this process.
La geografía de la Gran Moderación en América Latina
Authors: Carrasco Sánchez Carlos Alberto , Gainza Barrencua Xabier
Published: January 2024

Tras la crisis de la deuda en América Latina se pusieron en marcha una serie de reformas y ajustes estructurales con el fin de estabilizar las economías nacionales y reducir las fluctuaciones del ciclo económico. Por su parte, desde mediados de los años ochenta, los países desarrollados alcanzaron una mayor estabilidad en términos de inflación y crecimiento económico dentro del periodo conocido como la “Gran Moderación”. En este trabajo estudiamos el proceso de estabilización en América Latina de las últimas tres décadas a partir del análisis gráfico de las principales variables macroeconómicas. El análisis conjunto de estas variables nos permite abordar las causas comunes de la estabilización que se ha producido en la mayoría de países, así como algunas de las diferencias que todavía persisten.

En 2014 se cumplen 50 años de existencia de la Conferencia de Naciones Unidas para el Comercio y el Desarrollo (UNCTAD), un buen momento para hacer balance de sus logros y las dificultades.  Se trata del foro de diálogo más importante para debatir las cuestiones de desarrollo en las áreas de comercio, finanzas, inversiones y tecnología con una vida suficientemente larga como para valorar sus actuaciones.El poco eco y escaso interés de los especialistas en el seguimiento de sus actividades, nos anima a plantear este trabajo en el que se trata de poner de relieve las fortalezas y debilidades de esta institución así como sus nuevos enfoques de cara a los retos actuales de la economía mundial.
Distribución de la renta, beneficio y desigualdad: Una aplicación a la historia económica de Estados Unidos, 1910-2010
Authors: Manera Carles , Navinés Badal Ferran , Franconetti Manchado Javier
Published: January 2024

El trabajo analiza los ciclos económicos de Estados Unidos en el período 1910-2010, a partir de la evolución de la distribución de la renta y de las desigualdades sociales y su influencia sobre la tasa de beneficio. La investigación se desarrolla a partir de los registros de la contabilidad nacional de la economía norteamericana. Se plantea un objetivo básico: el análisis de la evolución en la distribución de la renta desde la observación de la tasa de beneficio. El estudio refuerza las conclusiones de la investigación de Thomas Piketty, con fuentes diferentes: una disminución de la participación salarial en la renta nacional y un aumento de las desigualdades sociales. Esto puede explicarse como una tendencia desplegada por el capital para mantener la tasa de beneficio que, al no poder corregir la tendencia decreciente en la productividad del capital, ha reforzado la explotación del factor trabajo.
Japanese Capital Internationalization and its Regional Leadership in Southeast Asia
Authors: Miñambres García Ignacio José
Published: January 2024

After a low profile international role in the 1990s, Japan has reasserted itself since the Asian financial crisis and is projecting capital again over the rest of Asia, at the same time that it tackles the emergence of a new competitor for regional leadership in China. In this paper we study the influence of government foreign policy objectives in shaping Japanese FDI and argue that Japan’s political ambitions of regional leadership have played an important role in the international investment decisions of its enterprises. This has in turn resulted in a particular structure of internationalization characterized by heavy presence of strategic-seeking FDI in developing economies, early adoption of cross-national outsourcing and horizontal production networks and a recurrence return to Southeast Asia as the natural area of internationalization for Japanese capital.

The “euro effect” and Outward Foreign Direct Investment
Authors: Tchorek Grzegorz , Brzozowski Micha
Published: January 2024

The "euro effect" is an important phenomenon in the debate on monetary in-tegration results in Europe. While in the existing literature the impact of the euro adoption is usually studied on trade data, the main goal of the paper is to examine whether the "euro ef-fect" can be detected in Outward Foreign Direct Investment (OFDI) flows from the OECD countries. Our approach is justified by the fact that trade and FDI are interconnected and both can be used as an internationalization strategy.Using the difference-in-differences method and the gravity equation corrected for the sam-ple selection and firm-heterogeneity biases, we investigate the trends of the strength of the impact of the euro over the 1985-2012 period. Our results suggest that the 'euro effect' is positive, is not time invariant and does not display a clear trend. It was the strongest in the years 2007 and 2008 and insignificant shortly after its introduction and during the global fi-nancial and European fiscal crises.
EVOLUTION OF INEQUALITY IN LATIN AMERICA (1980-2014): A MULTIDIMENSIONAL APPROACH BEYOND INCOME
Authors: Trueba Carmen , Remuzgo Lorena
Published: January 2024

Latin America is the region with the greatest inequality in terms of incomes. Thus, during the last years, the United Nations Development Programme (UNDP) has showed concern about the obstacle that inequality causes in the human development of this region. Given that higher economic growth does not necessarily lead to the achievement of further progress social, development beyond income will be one of the most important UNDP’s messages for its upcoming report for this region to be launched early 2016. In this paper, we propose a new multidimensional approach to study inequality in welfare in terms of the components of the Human Development Index of the UNDP –health, education and income– in the period 1980-2014. For this purpose we use the multidimensional inequality indices proposed by Maasoumi (1986) that can be decomposable into the between- and within-group inequality components.

Pension funds: conceptions of risk and the demand for ‘alternatives’
Authors: Bonizzi Bruno , Churchill Jennifer
Published: January 2024

The expansion and innovation of financial markets is closely linked to the growth of pension funds. While the conventional narrative is based on the notion of financial development as a positive change, this paper argues that pension funds may induce demand-led pressures on the financial system, generating potential for systemic risk and instability. The rise of pension funds is therefore important for the process of financialisation, as these institutions’ demand for assets continuously sparks growth and innovation in financial markets. In the current context pension funds are attempting to reduce risk by rebalancing their allocations away from equities towards ‘alternatives’, such as hedge funds and private equity. Coupled with the current regulatory trends towards risk-based funding regulation, we argue that pension funds are unlikely to be a stabilising force in financial markets today.
Entrepreneurial behaviour of dairy farmers under Dairy Business School model
Authors: GN Gayathri , Sankhala Gopal , Shivkumar Ramrao Yankam
Published: January 2024

Entrepreneurship has become the need of the hour with good potential to improve livelihood and generate employment. Most of the small and marginal farmers are dependent on dairy farming and there is a need to enhance the income of the farmers as per government priority to double their income. Hence entrepreneurship development in production, processing, and marketing is essential. So with the aim to inculcate entrepreneurial behaviour among dairy farmers, the Dairy Business School (DBS) was set up on an experimental basis at NDRI, Karnal a premier institute working on Dairy. The present study was conducted in 12 villages in six adjoining districts of NDRI, Karnal. An action research design was used with a sample size of 180 farmers during 2021-22. The data were collected through a pre-tested interview schedule by holding the personal interview. The results of the study revealed that the majority (61.11 %) of the farmers had a medium level of entrepreneurial behaviour. All the thirteen components of entrepreneurial behaviour like risk taking, hope of success, persistence, feedback usage, self confidence, knowledgeability, persuasability, manageability, innovativeness, achievement motivation, decision making ability, cosmopoliteness and profit orientation were at a medium level among dairy farmers. Knowledgeability was ranked first which contributed most to the entrepreneurial behavior of farmers while decision making ability at last.

Structural effects of inosine substitution in telomeric DNA quadruplex
Authors: Zheng Ya Ying , Dartawan Ricky , Wu Yuhan , Wu Chengze , Zhang Hope , Lu Jeanne , Hu Ashley , Vangaveti Sweta , Sheng Jia
Published: January 2024

The telomeric DNA, a distal region of eukaryotic chromosome containing guanine-rich repetitive sequence of (TTAGGG)n, has been shown to adopt higher-order structures, specifically G-quadruplexes (G4s). Previous studies have demonstrated the implication of G4 in tumor inhibition through chromosome maintenance and manipulation of oncogene expression featuring their G-rich promoter regions. Besides higher order structures, several regulatory roles are attributed to DNA epigenetic markers. In this work, we investigated how the structural dynamics of a G-quadruplex, formed by the telomeric sequence, is affected by inosine, a prevalent modified nucleotide. We used the standard (TTAGGG)n telomere repeats with guanosine mutated to inosine at each G position. Sequences (GGG)4, (IGG)4, (GIG)4, (GGI)4, (IGI)4, (IIG)4, (GII)4, and (III)4, bridged by TTA linker, are studied using biophysical experiments and molecular modeling. The effects of metal cations in quadruplex folding were explored in both Na+ and K+ containing buffers using CD and UV-melting studies. Our results show that antiparallel quadruplex topology forms with the native sequence (GGG)4 and the terminal modified DNAs (IGG)4 and (GGI)4 in both Na+ and K+ containing buffers. Specifically, quadruplex hybrid was observed for (GGG)4 in K+ buffer. Among the other modified sequences, (GIG)4, (IGI)4 and (GII)4 show parallel features, while (IIG)4 and (III)4 show no detectable conformation in the presence of either Na+ or K+. Our studies indicate that terminal lesions (IGG)4 and (GGI)4 may induce certain unknown conformations. The folding dynamics become undetectable in the presence of more than one inosine substitution except (IGI)4 in both buffer ions. In addition, both UV melting and CD melting studies implied that in most cases the K+ cation confers more thermodynamic stability compared to Na+. Collectively, our conformational studies revealed the diverse structural polymorphisms of G4 with position dependent G-to-I mutations in different ion conditions.

Published: January 2024

In this narrative inquiry research, our focus was on exploring teacher identity within the context of the expanding field of language teacher education and professional development. Utilizing theories of teacher identities to analyze data from interviews and reflections, we observed that conversations and stories were frequently shared in social settings, with overseas teaching practices being a substantial influence on their reflections. The findings indicated that the participants' teacher identities continually changed and dynamically evolved, particularly influenced by their engagement in overseas educational programs. Upon their return, participants expressed hope in maintaining their newly transformed perspectives on teaching and learning. In conclusion, we discussed further research directions and implications to underscore the ongoing significance of this topic.
Instant and short-term effects of acupuncture for depression and anxiety in unstable angina pectoris patients with percutaneous coronary interventions
Authors: Pei Juan Hui , Gan Feng , Bai Yun He , Xing Yan Lin , Jia Jian Jun , Wang Huan
Published: January 2024

Aim

Patients with unstable angina pectoris (UAP) usually present anxiety or depression during percutaneous coronary intervention (PCI). This study sought to investigate the instant and short-term effects of acupuncture for anxiety and depression in UAP patients with PCI.

Methods

A total of 210 UAP patients who underwent PCI were recruited and randomly assigned (1:1:1) to acupuncture, placebo, or control groups. Enzyme-linked immunosorbent assay was used to detect the levels of fasting glucose, fasting insulin, homeostasis model assessment of insulin resistance (HOMA-IR), interleukin-6 (IL-6), high-sensitivity C-reactive protein (Hs-CRP), advanced oxidation protein products (AoPPs), and oxidized low-density lipoprotein (OX-LDL). Serial questionnaires with the Hamilton Anxiety (HAMA) scale and the Pittsburgh Sleep Quality Index were evaluated, and heart rate variability indicators were obtained.

Results

Primary end-point: low frequency/high frequency (HF) was lower in the electroacupuncture group (p = 0.014), while standard deviation of normal-to-normal intervals, average standard deviation of normal-to-normal intervals, percentage of successive intervals that differ more than 50 ms, and HF were increased with acupuncture (p = 0.018, p = 0.043, p = 0.016, and p = 0.002, respectively). Secondary end-point: significant improvements in anxiety levels (HAMA) were observed in the three groups (p < 0.001). The fasting insulin and HOMA-IR levels were similar between the control group and the acupuncture group (p = 0.285 and p = 0.165, respectively). The levels of IL-6 and AoPPs differed among the three groups (p = 0.021 and p < 0.001, respectively). However, no significant differences were found in fasting plasma glucose, fasting c-peptide, Hs-CRP, and OX-LDL levels among the three groups (p = 0.585, p = 0.611, p = 0.902, and p = 0.756, respectively).

Conclusions

In this study, short-term acupuncture may potentially relieve clinical symptoms before PCI treatment.

Tropical cyclone intensity estimation through convolutional neural network transfer learning using two geostationary satellite datasets
Authors: Jung Hyeyoon , Baek You-Hyun , Moon Il-Ju , Lee Juhyun , Sohn Eun-Ha
Published: January 2024

Accurate prediction and monitoring of tropical cyclone (TC) intensity are crucial for saving lives, mitigating damages, and improving disaster response measures. In this study, we used a convolutional neural network (CNN) model to estimate TC intensity in the western North Pacific using Geo-KOMPSAT-2A (GK2A) satellite data. Given that the GK2A data cover only the period since 2019, we applied transfer learning to the model using information learned from previous Communication, Ocean, and Meteorological Satellite (COMS) data, which cover a considerably longer period (2011–2019). Transfer learning is a powerful technique that can improve the performance of a model even if the target task is based on a small amount of data. Experiments with various transfer learning methods using the GK2A and COMS data showed that the frozen–fine-tuning method had the best performance due to the high similarity between the two datasets. The test results for 2021 showed that employing transfer learning led to a 20% reduction in the root mean square error (RMSE) compared to models using only GK2A data. For the operational model, which additionally used TC images and intensities from 6 h earlier, transfer learning reduced the RMSE by 5.5%. These results suggest that transfer learning may represent a new breakthrough in geostationary satellite image–based TC intensity estimation, for which continuous long-term data are not always available.
Transcending traditional paradigms: the multifaceted realm of phenomenon-based learning

Published: January 2024

A framework characterizing the degradation of wind turbines for use in multiple-input damage-aware farm control is suggested. The focus is on the fatigue damage of the powertrain (drivetrain + generator) system, but the methodology may be extended to other components. A database of steady-state damage analyses for different operating conditions (average wind speeds, turbulence levels, power demands, and yaw misalignment angles) using aero-hydro-servo-elastic simulations is first generated. Then, a weighted damage index based on probabilistic long-term fatigue damage analysis of the powertrain system components is suggested and used to represent degradation at the farm level for control purposes. The focus is on curtailed conditions where the farm controller dispatches power commands to individual turbines in order to track a demanded power reference (rather than seeking to maximize power) at the farm level. As a secondary objective, the controller seeks to mitigate degradation through a smart combination of power commands and yaw offset angles, making use of the weighted degradation index. The potential of the proposed approach is demonstrated through a case study on the TotalControl Reference Wind Power Plant in a FLORIS-based simulation framework. The proposed farm controller is compared with the conventional one without damage mitigation feature and with damage mitigation but without yaw angle as the control input. It is found that combining yawing and downregulation effectively slows down degradation on the main bearing and powertrain as a whole.
Platinum desensitization therapy and its impact on the prognosis of ovary high-grade serous adenocarcinoma: a real world-data
Authors: Li Kemin , Yin Rutie
Published: January 2024

Background

To examine the value of five-step platinum desensitization therapy in epithelial ovarian cancer

Methods

A retrospective study was conducted on the high-grade serous adenocarcinoma of the ovary (HGSAO) patients who developed a platinum allergy during treatment and received desensitization therapy between January, 2016 and December, 2020. The logistic-regression was adopted to analyze the relationship between platinum desensitization therapy and prognosis in HGSAO patients.

Results

92 HGSAO patients were included in the study. Among these, 35 patients (38.0%) experienced mild allergic reactions, 51 (55.4%) experienced moderate allergic reactions, and 6 (6.5%) experienced severe allergic reactions. The desensitization therapy was successful in 86 patients (93.5%). Six patients had desensitization failure, of which five experienced severe allergic reactions during desensitization. The logistic-regression analysis revealed no significant correlation between platinum desensitization therapy and progression-free survival (PFS) or overall survival (OS) of patients (P < 0.05). However, the subgroup analysis demonstrated that the success or failure of platinum desensitization therapy significantly impacted the OS of patients who were platinum-sensitive recurrence. The patients who had successful desensitization therapy had a superior OS.

Conclusion

Five-step platinum desensitization therapy has potential application value in patients who were platinum-sensitive recurrence after first-line treatment but may bear the risk of severe allergic reactions.
The absence of a trade-off between morphological and syntactic complexity
Authors: Benítez-Burraco Antonio , Chen Sihan , Gil David
Published: January 2024

The hypothesis that all languages are equally complex often invokes a trade-off principle, according to which if a language is more complex in one particular domain, it will be simpler in another different domain. In this paper, we use data from WALS to test the existence of a trade-off between two specific domains: morphology and syntax. Contrary to widespread views, we did not find a negative correlation between these two language domains, but in fact a positive correlation. At the same time, this positive correlation seems to be driven by some language families, and it disappears when one considers purely morphological and purely syntactic features only. We discuss these findings in relation to ongoing research about language complexity, and in particular, the effects of factors external to language on linguistic structure.

We conducted a nationally-representative survey of United States (U.S.) adults (n=1,960) in 2021 to gather insights on the knowledge, perceptions, and concerns about threats to the ocean, with a specific focus on plastics and microplastic pollution. Responses from the U.S. adult survey group were compared to a group of highly-engaged, Ocean Conservancy members who are very attuned to ocean issues (n=882). Ocean Conservancy is a U.S.-based nonprofit environmental advocacy group working to protect the ocean from today’s greatest challenges. Plastic pollution was the primary ocean concern identified by both U.S. adults and Ocean Conservancy members, surpassing eight other threat categories including oil spills, chemical and nutrient pollution, and climate change. Broad concern was reported for both study groups about the impacts of ocean plastics on marine wildlife, with human health and coastal community impact concerns being less prominent. About half of U.S. adults and 90% of Ocean Conservancy members had heard of microplastics. Both study groups indicated widespread support for microplastic pollution prevention measures in the U.S. and believed industry to be most responsible for taking action to address it. Ocean Conservancy members were generally better informed and more concerned about plastic pollution impacts and microplastics than U.S. adults and reported significantly greater levels of personal action to reduce their plastic footprint when compared to U.S. adults. In general, U.S. adults reported a willingness to refuse single-use plastics, but less frequently brought personal food containers to restaurants for takeout, or contacted local representatives or businesses about reducing plastic waste and pollution. Overall, our survey results provide new insights about public understanding of ocean threats and plastic pollution, willingness to participate in individual plastic-reduction actions, and support for needed solutions.
Measurement of backscattering strength of artificial bubbles in the Southern Sea of the Korean Peninsula
Authors: Bae Ho Seuk , Kim Won-Ki
Published: January 2024

Bubbles greatly affect the propagation of sound waves as the acoustic characteristics of a bubble cluster in water are distinct from those of undisturbed water. Therefore, bubble clusters affect the ability of sensors to detect underwater targets by blocking or reflecting sound waves. Additionally, the bubble wakes produced by ships in movement can be detected by wake-homing torpedoes, thus greatly threatening the safety of the ship. Thus, research on bubble dynamics in water is crucial for the development of military technology. Recently, we conducted a quantitative estimation of the acoustic characteristics of artificial bubbles, including their backscattering strength, existence time, population density spectrum level and void fraction in an ideal water-tank environment. Based on our previous findings, the present study sought to measure the acoustic characteristics of artificial bubbles using an acoustic Doppler current profiler (ADCP) in the southern sea of the Korean Peninsula, which is a real marine environment. Additionally, we validated the ADCP measurements by comparing them to those obtained using a scattering strength measurement system (SSMS) developed by our team. Collectively, our findings provide a basis for the development of military technology, as well as for the study of bubble in water.
Comparative study on the dynamic response of an out-of-plane gradient bionic sandwich circular plate under two types of impact loading

Published: January 2024

Out-of-face gradient sandwich structures have been widely studied for their excellent impact resistance. One uniform and two out-of-plane gradient cores are proposed based on the bionic structure of Royal Water Lily, and the midspan deflection of the back panel and the energy absorption of the out-of-plane gradient sandwich structures under various blast loads are studied. Two frequently adopted methods of explosive loading are applied to the sandwich panels, and the responses are contrasted for the loads applied as a time-dependent pressure history versus imposition of the initial velocity. The effect of the fluid–structure interaction is considered in the blast impulsion, and the dynamic responses of the sandwich structures with different out-of-plane density arrangements are analyzed under two loading approaches. Results show that the energy absorption of the core layer under the prescribed velocity approach is approximately 3–5 times that of the applied pressure approach, while the back panel deflections of different out-of-plane gradient sandwiches are similar. There are significant differences in the deformation mechanisms of structures under these two types of impact loads. Under the same type of impact load, the core compression process of the out-of-plane positive gradient sandwich panel is decoupled from the whole tensile bending deformation process of the structure, whereas the core compression process of the out-of-plane negative gradient sandwich panel is strongly coupled with the whole tensile bending deformation process of the structure. The related research will lay the foundation for an in-depth understanding of the theoretical study of the impact of out-of-face gradient sandwich structures.
Loop closure detection of visual SLAM based on variational autoencoder

Published: January 2024

Loop closure detection is an important module for simultaneous localization and mapping (SLAM). Correct detection of loops can reduce the cumulative drift in positioning. Because traditional detection methods rely on handicraft features, false positive detections can occur when the environment changes, resulting in incorrect estimates and an inability to obtain accurate maps. In this research paper, a loop closure detection method based on a variational autoencoder (VAE) is proposed. It is intended to be used as a feature extractor to extract image features through neural networks to replace the handicraft features used in traditional methods. This method extracts a low-dimensional vector as the representation of the image. At the same time, the attention mechanism is added to the network and constraints are added to improve the loss function for better image representation. In the back-end feature matching process, geometric checking is used to filter out the wrong matching for the false positive problem. Finally, through numerical experiments, the proposed method is demonstrated to have a better precision-recall curve than the traditional method of the bag-of-words model and other deep learning methods and is highly robust to environmental changes. In addition, experiments on datasets from three different scenarios also demonstrate that the method can be applied in real-world scenarios and that it has a good performance.
