Authors: Mishin Dmitry V. , Gladkikh Anatoly A. , Kutuzov Vladislav I. , Attaby Aqeel Latif Khudair
Published: March 2024

Background. The need to use permutation decoding tools in radio communication systems is explained by the increased error correction capabilities of this method. In this case, complex matrix calculations during the search for equivalent codes according to the classical scheme of permutation decoding are replaced by a list of ready-made solutions. These solutions are calculated a priori and entered into the cognitive cards of the decoder processor, which makes the method a convenient tool in the procedure for ensuring information reliability when controlling, for example, unmanned vehicles via radio channels. In fact, matrix calculations on board are replaced by searching the list of cognitive maps for the right solution corresponding in real time to the current permutation of reliable character numerators. However, data processing in the decoder’s cognitive map requires a special description.
Aim. The study of methods for identifying permutations of character numerators of code vectors in order to effectively transform them in a system of cognitive maps of a permutation decoder.
Methods. The paper reveals the subtle structure of cognitive maps of productive and unproductive permutations of numerators, which allows on a regular basis to obtain an alternative solution for switching to a set of productive permutations when the receiver receives an unproductive permutation, thereby excluding the use of trial and error.
Results. The efficiency of the permutation decoder increases due to the implementation of permutations that were originally included in a set of solutions introduced into the cognitive map of unproductive permutations.
Conclusion. A family of microcontrollers is proposed to implement the principle of interaction of cognitive maps with a system of alternative solutions.
Entanglement between two charge qubits taking account the Kerr media
Authors: Bashkirov Eugene K.
Published: March 2024

Background. The need to implement controlled coupling between qubits, which are the logical elements of quantum devices such as quantum computers and quantum networks, requires, along with the use of traditional methods, the development of new, more effective ways to organize the interaction of qubits with the microwave fields of resonators used to generate and control the entanglement of qubits. As one of these methods, a method based on the influence of frequency-regulated radio frequency signals on a superconducting Josephson qubit connected by a large Josephson junction to a free qubit has been proposed.
Aim. The influence of the Kerr medium of the resonator, in which one of the two qubits is placed, on their entanglement induced by the coherent or thermal frequency-regulated radio frequency field of the resonator is considered.
Methods. To analyze the dynamics of the system under consideration, the solution of the quantum Liouville equation for the full density matrix is studied. An exact solution o this equation is found in the case of initial separable and entangled states of qubits. The exact solution of the evolution equation is used to calculate the criterion of qubit-qubit entanglement – cconcurrence. Numerical modeling of the concurrence was carried out for various states of qubits, coherent and thermal fields of the resonator, as well as various values of the intensity of the resonator field and the Kerr nonlinearity parameter.
Results. It is shown that for separable initial states of qubits, the inclusion of Kerr nonlinearity reduces the maximum degree of entanglement of qubits. For an entangled initial state of qubits, the possibility of creating long-lived entangled states in the presence of Kerr nonlinearity is shown.
Conclusion. The type of initial states of qubits and the range of values of the intensities of the resonator fields and the Kerr nonlinearity parameters have been established, for which the most effective control and operation of the evolution of qubits, as well as the degree of their entanglement, in the physical system under consideration, is possible.
CEFR-based Model of Indonesian Grammar Teaching Materials for Foreign Students
Authors: Muliastuti Liliana
Published: March 2024

Law No. 24/2009 mandates the internationalization of the Indonesian language that is in line with the increase in the learning of the Indonesian language for foreign speakers. The number and location of Indonesian speakers are increasing and expanding in various parts of the world. However, the existing teaching materials are not optimal in supporting BIPA teaching, especially in the aspect of grammar—the most difficult language component for foreign students to learn. Thus, it is imperative to develop a model of Indonesian grammar teaching materials based on the current curriculum that refers to CEFR. This research focuses on the development of an Indonesian grammar teaching material model for A1-level BIPA students. The development design employed is an adaptation of the R&D design by Borg and Gall, which consists of several phases, such as (1) model development, (2) model evaluation, and (3) production and dissemination. This initial research constitutes a model development phase that includes (a) needs analysis, (b) needs identification based on the existing Indonesian grammar teaching materials and studies on the document of CEFR-based BIPA Graduate Competence Standard, and (c) compiling Indonesian grammar teaching materials. This preliminary research results in the mapping and drafting the initial product of the model of Indonesian grammar teaching materials for students at the A1 level.
Keywords: teaching material model, Indonesian grammar, BIPA (Indonesian Language for Foreign Speakers), CEFR
CATALYST BASED ON PALLADIUM(II), COPPER(II) COMPOUNDS AND THERMALLY-MODIFIED TRIPOLI FOR THE PREPARATION OF RESPIRATORY REMEDIES FROM CARBON MONOXIDE IN EMERGENCY SITUATIONS
Authors: Kiose T. O. , Rakytska T. L. , Holubchyk K. O.
Published: March 2024

Nowadays, the number of emergency situations related to fires is quite high. The high percentage of human deaths is mainly due to poisoning by gaseous toxic substances including carbon monoxide. The most problematic issue is the development or application of existing catalysts in means of individual protection of human respiratory organs – respirators, gas masks, self-rescuers. The compositions based on thermally modified tripoli obtained by the method of impregnation of the carrier by moisture content with compounds of copper(II), palladium(II) and potassium bromide were investigated. According to X-ray phase analysis, it was established that thermally modified tripoli is a polyphase crystalline mineral containing the following main phases: a-quartz, a-tridymite, b-cristobalite, a-cristobalite. The influence of the initial concentration of CO, which does not exceed 15 MPC, on the kinetic and stoichiometric parameters of the reaction varied in the range from 100 to 300 mg/m3. It was noted that the reaction rate in the stationary mode (Wst) is directly proportional to the increase in the initial concentration of carbon monoxide in the gas phase. The values of the constant kI and the degree of CO conversion (ηst) do not depend on CinCO, which also confirms the first order of CO concentration. Particular attention is paid to the aspects of ensuring protection against carbon monoxide when its concentration exceeds 15 MPC. Usually, special equipment, such as filtering self-rescuers, is used to clean the air from carbon monoxide at concentrations from 1000 to 6500 mg/m3. The catalyst developed by us is intended for use in lightweight personal respiratory protective equipment (RPE) at concentrations not exceeding 15 MPC. Therefore, there was an interest in researching the possibilities of using this catalyst in the self-saving filter system. The concentration of carbon monoxide in the gas-air mixture was varied from 400 to 2500 mg/m3 in the presence of the К2PdCl4-Cu(NO3)2-КBr/300-Tr(K) system. It was established that Wst increases in direct proportion with an increase in the gas-air mixture up to 1250 mg/m3, which indicates the first order of the reaction according to carbon monoxide. It was found that at CinCO = 1000 mg/m3 only under the condition τ´ = 1.13 s (mk = 10 g) the К2PdCl4-Cu(NO3)2-KBr/Tr catalyst provides air purification below the breakthrough CO concentration (CfCO = 200 mg/m3). Experiments on the influence of SO2 on the activity of carbon monoxide oxidation catalysts have shown that they lose their activity, so in air purification systems from CO, it is necessary to provide for the stage of capturing sulfur dioxide.

The influence of the B2O3 additive on the nature of the interaction in the SiO–GeO2 system was investigated by X-ray diffraction and IR transmission spectroscopy. The nature of the diffractograms of the SiO–GeO2–B2O3 system with a composition of 1:1:0.5 and 1:1:1 corresponds to the presence of SiO2 phases of hexagonal modification (quartz) and GeO2 of various modifications, as well as, possibly, a crystalline B2O3 phase. The exact value of the content of the reaction products and initial components could not be determined due to the significant content of the X-ray amorphous component of unknown composition. The broadening of the diffraction peaks and the presence of a distinct halo testify to the benefit of the processes of nanostructuring and glass formation. However, the absence of elemental germanium in the SiO–GeO2–B2O3 system, in contrast to the SiO–GeO2 system, was clearly established. The nature of the IR transmission spectra of samples with different content of B2O3 additive differ significantly from each other. Thus, the IR transmission spectra of the sample with a composition of 1:1:0.5 contain weak absorption bands due to the oscillations of the B–O bonds; instead, they reveal periodic oscillations characteristic of nanostructured systems. In the spectra of the sample with a composition of 1:1:1, the absorption bands due to the oscillations of the B–O bonds are very distinct, but there are no oscillations. Therefore, the addition of B2O3 probably accelerates the formation of Germanium monoxide, which in turn reacts with the B2O3 additive and possibly with SiO2 as one of the reaction products.
Testing of samples of the SiO–GeO2–B2O3 system by the method of thermal evaporation in a vacuum revealed the advantages of the sample with a composition of 1:1:1 in the ability to form a strong and durable coating. It was possible to determine the refractive index for it, which is 1.93 at a wavelength of 1000 nm. Instead, the coating obtained from the 1:1:0.5 composition sample turned out to be unstable. A conclusion was made about the need for further optimization of the composition and synthesis conditions to obtain materials with the required parameters.

Authors: Fadillah Ridha , Hani'ah
Published: March 2024

This research is a sociolinguistic study of the honorific in Madurese and Banjarese societies to glorify an ulama and his family as a form of their respect. This research aims to describe the differences and similarities between honorific patterns in the two groups of society. This research uses a qualitative descriptive method. The data collection techniques used in this research are observation techniques, interviews, proficient free-involved listening techniques, as well as note-taking and recording techniques. Data analysis techniques are carried out by applying an interactive model which consists of three components, namely data reduction, data presentation and interpretation, and withdrawal and verification. The findings of this research show that the Madurese and Banjarese have similarities and differences in honorific patterns as a form of their respect for ulama. Madurese show respect with an honorific pattern to ulama and all members of families, while Banjarese give honorific for the ulama only, while their family does not have a special tittle for honorifics. Based on the results of this research, it can be concluded that in general there are two patterns of honorific, both in South Kalimantan and Madura. Honorific in Banjarese have two points, (1) the word Tuan/Guru + regional name, (2) the word Tuan/Guru + a typical Banjarese nickname, namely adding the sound [i] before the name of the ulama. Meanwhile, Madurese also have two patterns, but they are slightly different. (1) The word kèyaè + regional name, (2) the word kèyaè + name of ulama. The similarities are that they both have a special honorific form that only applies to one ulama, and both have a pattern that uses regional names.

Published: March 2024

Relevance. The fact that hydrogenic deposits are developed using combined technologies, and the criteria for combining technologies have not been sufficiently developed.
Aim. To select the optimal method of deposit development, taking into account the characteristics of the uranium ores composing it. Objects. The Semizbai sandstone deposit, which lies in loose sedimentary rocks, is localized within a 36 km long section with a width of 10 km. Methods. Analysis of the theory and practice of field development, finding dependencies between operational indicators, modeling, methods of mathematical statistics, technical and economic calculations and approbation of some provisions. Results. The authors have given characteristic of systems for developing hydrogenic deposits and substantiated the necessity of combining metal extraction technologies by leaching with traditional technologies in the conditions of the deposit. Alternative technologies for metal leaching using interacting wells and with metal leaching in a pile are detailed. The mechanism and differences in the conditions of uranium leaching in a quicksand array and in a heap was clarified. The authors have carried out comparative characteristic of alternative options for field development, indicating, among other things, their advantages and disadvantages. It was determined that leaching parameters depend on speed and efficiency of opening new reaction areas with a different mechanism for removing uranium from mineral particles. It is proved that the efficiency of the development of hydrogenic deposits is increased by combining the processes of borehole hydro extraction of ores and heap leaching of metals. The authors proposed the model of decision-making sequence with an arbitrary source of information based on the criterion of discounted profit from mining. Conclusions. The results of the study may be in demand when revaluing reserves, modernizing systems for the development and optimization of methods for managing the quality of mining products. The recommended methods of monitoring the combined development of hydrogenic deposits contribute to increasing the completeness of subsurface use.

Published: March 2024

Relevance. The fact that composites with a metal matrix and structural products based on them are in great demand in various industries, including the automotive industry, aerospace industry, and shipbuilding. Aluminum matrix composites are the most popular since they combine the excellent ductility, low density, good corrosion resistance of aluminum and the high strength, hardness and wear resistance of a ceramic reinforcing component. Aim. To obtain bulk Al-WC metal matrix composites with different contents of the reinforcing phase and with increased physical and mechanical characteristics using spark plasma sintering. Objects. Sintered bulk products made of pure aluminum and obtained at 400, 450, 500, 550, 600°C and bulk metal matrix composites Al-1%WC, Al-5%WC, Al-10%WC, Al-15%WC obtained at 600°C. Methods. Spark plasma sintering; X-ray diffractometry (XRD phase analysis); scanning electron microscopy; indentation (microhardness measurement). Results. The authors have obtained bulk composite metal matrix products with an aluminum matrix and tungsten carbide as a reinforcing component. Compacting mixtures of nanosized initial powders of aluminum and tungsten carbide using spark plasma sintering made it possible to obtain products with a WC content of 1 to 15 wt %. Taking into account the results of a preliminary series of experiments, when pure aluminum samples were sintered to determine the optimal sintering temperature, bulk composite materials were obtained. A distinctive feature of the obtained samples is their high degree of compaction, which is due to the simultaneous application of a heating current and external pressure, coupled with the relative preservation of the fine-grained structure of the material due to the short process time. The analysis of various sintering modes revealed the need to carry out sintering of composites at 600°C. The research has shown that, although adding a reinforcing phase to a metal matrix significantly reduces the degree of compaction of the material from 97.45% in the absence of an additive to 62.32% with the addition of 15%WC, an increase in the microhardness of products is observed when the concentration of the reinforcing component increases from 3.95 to 5.75 HV. This proves the possibility of reinforcing a metal material using ceramic WC particles. The results can be used in a variety of structural applications, including automotive and aerospace.

Authors: McGovern Justine , Hellstrom Ingrid , Oyebode Jan
Published: March 2024

Background: This article examines the intersection of two global trends, super-diversity and globalized aging, in the context of urban communities. Super-diversity refers to the impact of changing immigration patterns on social, health, and economic systems. Interdisciplinary by definition, gerontological social work practice bridges macro, mezzo, and micro modalities, as well as professional and disciplinary false divides.

Objective: The authors aim to highlight how urban gerontology practice can benefit from reaching across borders and boundaries. Goals include identifying best practices of care that can serve as models in a range of environments.

Methods: The authors used a qualitative case study approach. Data collection consisted of individual interviews and focus groups.

Findings: Findings suggest the ongoing relevance of ecological theory in the context of identifying best practices in social work gerontology.

Discussion: Through the lens of super-diversity and globalized aging, the authors examine processes and impacts at the intersection of migration, advanced age, and care systems in the urban context. Findings indicate the need to further de-colonize aging care.
Trends in the integration of researchers into the social division of labor
Authors: Savinkov Vladimir , Sheregi Franz
Published: March 2024

As the functional role of science in the development of the economy expands, specialists of scientific organizations are becoming an increasingly significant subject of the social division of labor. On the basis of open data of official statistics and the results of a nationwide representative study, the authors of the article show that the expansion of the economic role of science workers is accompanied by the transformation of a large part of their intellectual activity into creative engineering for innovative production. At the same time, the labor of the majority of scientists is transforming from exclusive to mass-production, bringing the nature of their living conditions closer to the way of life of workers of mass professions, partly transforming into precarious labor. At the same time, it is shown that the formation of precariat is not a deviation in the classical form of wage labor, but the transformation of the proletariat as a class into precariat, which is also characteristic of scientific workers.

Authors: Galkin Konstantin , Rassolova Elena
Published: March 2024

The article presents a scientometric analysis of publications on citizen science, i.e., conducted with the participation of non-professional scientists, posted on the portal of the journal Nature, in order to identify the main directions and thematic trends in the field of citizen science over the last 5 years. The article identifies the key thematic clusters to which the reviewed publications belong, and analyses the thematic trends in each of the presented clusters. The search was carried out in English among the publications posted on the portal in the period from 2019 to 2023. The result is presented using computer visualisation and a table of key topics of the reviewed publications; in the future it is planned to expand the study and build a thematic map and scheme of key trends both abroad and in Russia. The analysis shows that the key topics in which volunteer researchers have been involved over the last 5 years have been environmental protection and conservation, publications on biodiversity and climate change, and data analysis in ecology. The authors note a widespread and growing interest in finding scientific volunteers to conduct research, as well as the growing role of volunteer researchers. The participation of non-professional scientists encourages a shift towards interdisciplinary research and promotes the use of different research methodologies. There are trends in the transformation of the role of volunteer researchers from the status of ordinary field researchers to full-fledged participants in research work.
PRIVATE EQUITY FUND SELECTION - A MACHINE LEARNING APPROACH
Authors:   Department of Strategy and Marketing, Stockholm School of Economics, Stockholm, Sweden, Rosenqvist Christopher
Published: March 2024

The following aims to train a range of supervised machine learning models to predict the probability of a private equity (PE) fund exceeding a public market equivalent (PME) measure of 1 based on the information the PE investor would have at the time of fundraising. Past literature has studied a range of factors that appear to drive the performance of PE funds such as targeted fund size, management experience, fund specialization level, state of the industry, and the overall economy. The article investigates the predictive power of these factors. The models are based on a sample of 1,233 Buyout (BO) funds and 689 are Venture Capital (VC) funds sourced from Preqin. The results suggest some degree of predictability in VC funds with the top performing models reaching an out of sample accuracy score of 75% vs a base rate of 70%. For BO funds, the results are less promising with the top models only reaching an out of sample accuracy score of 60%, while failing to surpass the base rate of 61%. Overall, complex machine learning models, such as boosted decision tree-based algorithms and feedforward neural networks, fail to consistently outperform simpler models in both fund categories, which can be attributed to the limited sample size. Many macroeconomic and fund-specific in the variables analysis look to be valuable performance indicators for both the categories of funds. The impact is more profound and statistically significant for VC funds, especially in the case of macroeconomic factors.

Authors:   Department of Economics, University of Jaén, Jaén, Spain, Cárdenas-García Pablo Juan
Published: March 2024

Currently, a significant number of countries are betting on tourism as an economic activity on which to base their economic development, given that most international organizations recognize that tourism can become a tool for economic development, especially in less developed countries. However, on the part of the scientific literature there is no defined current on the capacity of tourism to become an instrument with which to improve the living conditions of the population residing in receiving countries. In this sense, in the scientific literature there are numerous investigations that have dealt with analysing the relationship between tourism and economic growth, a large part of these works coinciding that there is a causal relationship between both variables, but the same does not happen when the relationship between tourism and economic development. Among works that have analysed this relationship, there is no uniform current on the relationships that exist between tourism and economic development, being different the variables that have been used in these works to measure tourism and economic development, and being applied in different areas of analysis. Indeed, since the appearance of the first works that have analysed the relationship between tourism and economic development, approximately ten years ago, a large number of investigations have emerged on this relationship, for which it is interesting to carry out an evaluation of the main models econometrics that have been used, as well as the main empirical findings that have been reached in this work. In this context, this work highlights a comprehensive review of a large number of peer-reviewed articles that analyse the relationship between tourism and economic development, providing a general description of the theoretical framework that supports the relationship between these two variables, as well as the main results that have been obtained in these works, which will allow establishing the position of the scientific literature regarding the capacity of tourism as an instrument of economic development. This work, therefore, contributes to the scientific literature by answering the question: what is the relationship between tourism and economic development?

Purpose –The main subject of the research is the relationship between organizational resilience and crisis management. Organizational resilience, which is handled with its planned and adaptive dimensions, is referred to as the capacity that enables organizations to survive in harsh environmental conditions and to manage the crises encountered, is often on the agenda with crisis management. On the other hand, crisis management, which covers the processes before, during and after the crisis and is the subject of many researches in the literature, also underlines the organizational resilience in these processes. It is aimed that this research will contribute to the literature, since the studies examining the relationship between these two related concepts are few in quantity. The small number of studies examining the subject on hospitality businesses makes this research unique.Design/methodology/approach –The universe of the research consists of top and middle level managers in 5-star hospitality businesses located in Ankara. Quantitative research method was used as the data collection method in the study, in which a sample of 193 managers was reached, and data were collected with these managers in 27 hospitality businesses through a semi-structured questionnaire.Findings–In line with the findings, it was determined that there is a relationship between the concepts and that organizational resilience has an effect on pre-and post-crisis periods on the other hand, crisis period has an impact on adaptive resilience.Discussion–Based on the results of the research, it has been deduced from the literature that organizational resilience is a higher-frame concept than crisis management at the same time, the concepts are intertwined and complementary in management process and that organizational resilience, in practice, must have certain requirements, especially experience in managing crises, and organizations that want to operate in the long term should not ignore resilience.

Amaç-Bu çalışmanın amacı; Borsa İstanbul (BIST) Holding ve Yatırım Şirketleri (XHOLD)’nin verilerine dayanarak ilgili şirketlerin kurumsal sahiplik yapıları, tahakkukları (muhafazakârlık) ve muhasebe zararlarını tazminlerinin vergiden kaçınma üzerindeki etkisini araştırmaktır.Yöntem -Araştırma amacı doğrultusunda ilgili endekste yer alan 50 işletmeden verilerine eksiksiz bir şekilde ulaşılan 40 işletme araştırmaya dâhil edilerek 2011-2022 yılları arasında ilgili işletmeverileri Kamuyu Aydınlatma Platformu (KAP)’nda yer alan ve bağımsız denetimden geçmiş olan güvenilir mali tablolardan elde edilmiş panel veri analizi yöntemiyle analize tabi tutulmuştur.Bulgular-Araştırma sonuçlarına göre muhasebe zararları tazmininin vergiden kaçınma üzerindeki etkisi pozitif, tahakkuklar yani muhasebe muhafazakârlığının vergiden kaçınma üzerindeki etkisi ise negatif yönlüdür. Ancak kurumsal sahipliğin vergiden kaçınma üzerinde herhangi bir etkisi tespit edilememiştir.Tartışma-Vergiden kaçınmanın yasal ve ahlaki boyutu literatürde bir tartışma konusu iken, işletmelerin vergiden kaçınma faaliyetleri yerine şeffaf ve dürüst raporlama yapmanın kamuoyu nezdinde daha olumlu, kamu otoritesinin de vergiden kaçınmaya yönelik kanun boşluklarını yeniden gözden geçirmesinin ise daha yararlı bir faaliyet olacağı ifade edilebilir.
Productive and Decent Work Employment Opportunities: Reflections of Sustainable Development Goal 8
Authors: Chahal Deepika , Rani Anju
Published: March 2024

This study measures the impact of seven indicators of Sustainable Development Goals (SDGs) on Goal 8, which is about productive and decent work and employment opportunities in India. The study employs pooled ordinary least squares (POLS) methods to capture the impact of seven indicators— annual growth rate of real GDP per capita, ease of doing business, unemployment rate, labour force participation rate, participation of informal workers, fatal and non-fatal occupation injuries, and banking outlets, on SDG 8, for 2018-2021. The findings reveal that the annual growth rate of real GDP per capita, labour force participation rate, and ease of doing business influence SDG 8’s score positively and significantly. On the contrary, the unemployment rate impacts sustainable score value negatively and significantly. The inferences of the study did not unwrap a significant effect of the percentage of workers in the informal sector, fatal and non-fatal occupation injuries and the number of banking outlets on SDG8. The study recommends reducing unemployment and increasing labour force participation rates in the economy for sustainability. At the same time, policymakers must focus on enhancing the ease of doing business and the annual growth rate of real GDP per capita to realise decent work and employment opportunities. To advance sustainable development goals, especially SDG 8, fostering sustainable and inclusive economic growth is the need of the hour.

Currently, there are many advanced and proven evaluation methods. However, there is practically no work on the systematisation of evaluation criteria considering management levels, tasks, and functions. The purpose of the study is to develop a systemological model for assessing the managerial potential of personnel, which combines the main components that determine the effectiveness of the organisation’s management staff.   This study involved 48 males and 34 females aged 23 to 66 years, performing the role and functions of a leader. The primary condition for selecting the participants for the study was based on the level of higher education and managerial experience. All respondents were divided into five groups based on their qualifications, as well as the experiences gained from the management activities. To accomplish the study’s objectives, an evaluation list of criteria was compiled, which made it possible to systematise the managerial potential of personnel based on management levels, tasks, and functions performed. The findings of the study demonstrate systematisation of approaches to managerial potential from the organisation’s perspective, which in turn allowed us to build a systemological model for assessing the managerial potential of personnel.
Observed interannual variability and projected scenarios of drought in the Chorotega region, Costa Rica

The observation-based analysis of drought development in the Chorotega region showed that, despite the area being relatively small, agricultural drought exhibits high spatial variability across the region. However, the lack of net radiation data hinders the capacity to provide reliable estimates of evapotranspiration (ET), affecting the assessment of drought occurrence, since its propagation across the hydrological system is very sensitive to the ET estimation method. The coarse resolution of satellite-derived Normalized Difference Vegetation Index (NDVI) products and the lack of information on irrigation in agricultural areas limits the ability to properly establish a relationship between drought and vegetation response. Based on the observations, the most prominent precipitation deficits occur between September and October (–100 mm on average), showing that changes in the large-scale circulation are responsible for the impact of severe drought in the region. In agreement with previous studies, El Niño-Southern Oscillation (ENSO) is the main modulator of the drought severity, with the warm ENSO phase favoring an enhanced drought development and its influence being more significant between August and October, displaying correlations greater than –0.6. The climate change projections under RCP4.5 and RCP8.5 scenarios suggest the intensification of drought events in the Chorotega region at mid-century, with the Tempisque-Bebedero basin being the most affected area in terms of precipitation decrease and warming. The projected scenarios correspond to an increase of 1 oC for mean temperature and more of 2 oC for minimum and maximum temperature in the 2050 horizon, as well as a decrease of 400 to 800 mm for annual precipitation under both RCPs.
A Neural-Network-Based Watermarking Method Approximating JPEG Quantization
Authors: Yamauchi Shingo , Kawamura Masaki
Published: March 2024

We propose a neural-network-based watermarking method that introduces the quantized activation function that approximates the quantization of JPEG compression. Many neural-network-based watermarking methods have been proposed. Conventional methods have acquired robustness against various attacks by introducing an attack simulation layer between the embedding network and the extraction network. The quantization process of JPEG compression was replaced by the noise addition process in the attack layer of the conventional methods. In this paper, we propose a quantized activation function that can simulate the JPEG quantization standard as it is in order to improve the robustness against the JPEG compression. Our quantized activation function consists of several hyperbolic tangent functions and is applied as an activation function for neural networks. Our network was introduced in the attack layer of ReDMark proposed by Ahmadi et al. to compare it with their method. That is, the embedding and extraction networks had the same structure. We compared the usual JPEG compressed images and the images applying the quantized activation function. The results showed that a network with quantized activation functions can approximate JPEG compression with high accuracy. We also compared the bit error rate (BER) of estimated watermarks generated by our network with those generated by ReDMark. We found that our network was able to produce estimated watermarks with lower BERs than those of ReDMark. Therefore, our network outperformed the conventional method with respect to image quality and BER.

Abstract: Fetal Alcohol Spectrum Disorder (FASD) is considered a lifelong disability that has been framed by neurobiological descriptions focused on the brain. These are important features but fail to tell the story of living with FASD. By surveying those with FASD, this work expands upon prior survey work which illustrated a multitude of early onset physiological issues occurring at rates much higher than typical of the general population. The current project, again using an anonymous survey methodology, seeks to open up other direct experiences to better understand the complexity of living with FASD. An anonymous online survey was used to gather data on advresity in childhood, schooling, employment, housing and finances, involvement with the criminal justice system as well as relationships and parenting. Results inform how supports can be enhanced and targeted with a goal of improving the quality of life. The survey was developed by adults living with FASD who have served as a long-standing advocacy and educational group influencing policy and practice in the field.
