Según Angel Losada, el dictamen ético que Avendaño da en su Thesaurus Indicus acerca de la esclavitud de los negros influyó decisivamente para que las Cortes europeas abolieran tal esclavitud1 . No entraremos ahora a discutir este aspecto. Lo cierto es que nuestro autor es uno de los pocos en abordar decididamente el tema y uno de los que más espacio le dedica, convencido de que «se trata de un asunto de tal modo riesgoso para las conciencias cristianas que, de ceñirse a las normas de la justicia, apenas habrá algo en lo que puedan estar totalmente tranquilas en tales contratos»2 . El autor al que Avendaño parece dar más crédito en este tema es el también jesuita Luis de Molina, quien según el autor del Thesaurus, «estudió el asunto con sumo cuidado al escribir respecto a los portugueses»3 . No es de extrañar, ciertamente, que vinculado Molina a la Corona española por nacimiento, y conocedor de cómo manejaba el asunto la portuguesa, por haber desempeñado su labor docente en Coimbra, no solo tuviera especial interés en emitir opinión al respecto, sino que habremos de pensar también que estuvo en mejores circunstancias que otros autores para poder opinar.

Escritura preclásica en el sur de Campeche: las pinturas murales de Chakjobon
Authors: Grube Nikolai Grube
Published: April 2023

En este artículo se publican por primera vez las pinturas murales de una cámara funeraria en el pequeño sitio de Chakjobon, en la Reserva Balam Ku, en el sur del estado de Campeche. Por razones estilísticas las pinturas murales deben considerarse contemporáneas a las de San Bartolo en Guatemala. La gran importancia de las pinturas de Chakjobon radica en que contienen dos textos jeroglíficos muy tempranos y, por tanto, complementan el limitado corpus de textos del Preclásico Tardío encontrados in situ. Los signos de escritura muestran fuertes paralelismos con los textos de San Bartolo, pero también con los de la Estela 10 de Kaminaljuyú, y sugieren que ya en el Preclásico Tardío debió existir una comunicación supraregional entre las comunidades de escribas sobre los signos y sobre la escritura en general. Se puede suponer que la escena del trono representada en la pintura, así como los textos escritos, se referían a la persona enterrada en la cámara funeraria.
Toniná, Chiapas. Nuevas prácticas en torno al sacrificio humano en las postrimerías del colapso maya
Authors: Ruiz González Judith Lizbeth
Published: April 2023

Se dan a conocer nuevos datos osteológicos sobre la práctica del sacrificio humano entre los mayas del Posclásico, a través del estudio arqueotanatológico de un depósito masivo u osario en la antigua ciudad de Toniná, en las Tierras Altas del occidente del Área Maya. El hallazgo arqueológico se suscitó en 1991, cuando se exploraba uno de los templos de la quinta plataforma de la Acrópolis. Se aplicaron varios análisis: morfológicos y arqueométricos, que dan cuenta del perfil biológico y permiten documentar la práctica del sacrificio humano y los tratamientos póstumos de las víctimas. Así también los análisis isotópicos aportan información sobre la historia residencial y los conflictos internos en el valle de Ocosingo.
El problema de la decadencia en el Chiapas tardocolonial
Authors: Guillén Villafuerte José Javier
Published: April 2023

En la historiografía sobre Chiapas es común afirmar que durante los últimos años del periodo colonial la economía provincial entró en crisis. El objetivo de este ensayo es mostrar que los documentos que han servido de base a este argumento contienen información muy poco fiable. En este sentido, utilizaré materiales de archivo para someter a revisión dichas fuentes y, además, intentaré mostrar que existe suficiente evidencia de que, en algunas regiones de la provincia, lejos de atravesar una crisis, la demografía, la agricultura y el comercio se expandieron durante los últimos años del siglo XVIII.
Orígenes de la lexicografía del español en América: primeros repertorios y esbozos metodológicos
Authors: Fajardo Aguirre Alejandro
Published: April 2023

The origins of the lexicography of Spanish in America are found in various works such as glossaries, vocabularies, relationships, indexes, tables, etc., which have some common characteristics: they are simple and concise repertoires that are created because they are useful to understand the historical-geographical and literary texts, being usually appendices of a few dozens of words; in some cases they contain technical words or are included in dictionaries of another type. Twelve of these works are analyzed up to the beginning of the 17th century to show how lexicographical methods and techniques are outlined, which are the embryo of the later concept of dictionary of Americanisms.
La transgresión de la letra. Poética y feminismo en Cristina Peri Rossi
Authors: Domínguez Galván Zaradat
Published: April 2023

This article investigates the transgressive will of female and feminist poetry in the poetic work of the writer Cristina Peri Rossi, who has recognized pursuing an ethical will of writing to face the injustices of her time. Recently, she has been awarded the Cervantes Prize 2021, the most important award in Spanish-language literature, granted by the Ministry of Culture and Sports, which is given to the recognition of an entire literary career. The objective of this essay has been to verify how in many of her verses Cristina Peri Rossi, aided by the word poetic, puts together a discursive strategy against the prevailing machismo and misogyny. A large part of the Rossinian poetic work is articulated as well as a space of resistance facing an androcentric canon that has made female writing impossible and invisible. Not in vain, Peri Rossi’s writing project was originally born as a transgression of the female fatum, conquering the place of enunciation, taking the poetic voice and subverting through language the writing that had been denied to her.
“Frondibus et ramis Dapnes imitata decorem” (Lyr. I, 94). Mito y metamorfosis en la Lyrae Heroyca (1581) de Francisco Núñez de Oria
Authors: Fernández Ríos María
Published: April 2023

In this paper we have focused our attention on the Neo-Latin epic poem entitled Lyrae Heroycae libri quatuordecim (Salamanca, Matías Gast, 1581) by the Spanish humanist Francisco Núñez de Oria. This epic poem, as little known as its author, combines two a priori antagonistic traditions: the classical epic canon and the novel subject of chivalry. However, we can also observe a notable influence of Ovid in this poem, as well as of Breton literature, who, although to a lesser extent than Virgil, is very present in the different metamorphoses of characters and in different allusions of a mythological nature. In the following pages, we will study how the humanist uses these transformations and mythological allusions from different traditions in a Christian key, as part of the same symbolic reading.
La activación del significado adecuado: un estudio experimental sobre palabras ambiguas en contexto
Authors: López-Cortés Natalia , Horno-Chéliz María del Carmen
Published: April 2023

The aim of this article is to offer a revision of the processing of the synchronic polysemous and homonymous words within a context. According to Swinney’s results (1979), when an ambiguous word is processed all its meanings are always activated. Nonetheless, the difference between types of ambiguity was not considered. The experiment here presented consisted of a reading task with priming. It was carried out by 24 participants and measured using an eye-tracker device. The current results indicate that there is a differential behaviour depending on the type of ambiguity and that Swinney’s proposal is consistent with polysemous words but not with homonymous units.
Narrativas de la diversidad cultural en el siglo XVI. A propósito de las notas históricas de fray Diego de Guadix
Authors: Moreno Moreno María Águeda
Published: April 2023

The diversity of ideas and values between different societies neither can be reduced nor judged as a cultural element from another society, being the only important matter that makes sense within that same culture. From this perspective, this article analyses the dictionary of Diego de Guadix (ca. 1593) to find out how through his narrative this author describes different socio-cultural systems and speaks of the “Others” from an ethnocentric “We”, based on a unilinear socio-religious concept.

Laser-Induced Graphene on Optical Fibre: Towards Simple and Cost-Effective Electrochemical/Optical Lab-on-Fibre Bioplatforms
Authors: Ribeiro Rafael A. , Ferreira Laura L. , Fernandes António J. S. , Da Costa Florinda Mendes , Marques Carlos , Santos Nuno F.
Published: April 2023

A 3D graphene foam made of interconnected multilayer graphene flakes was produced on optical fibres (OF) by laser-induced transformation of a polyimide (PI) film coated on the OF cladding. This material, known as la-ser-induced graphene (LIG), was explored in the electrochemical detection and quantification of dopamine (DA) at physiologically relevant concentrations in the presence of the most relevant interfering molecules in biological fluids, ascorbic acid (AA) and uric acid (UA). The measured limit of detection is 100 nM, the linear range is 0.1 to 5 μM and a maximum sensitivity of 5.0 µA µM−1 cm−2 was obtained for LIG decorated with Pt nanoparticles (NPs). Moreover, immunity to AA and UA interference and to fouling was attained by decorating the LIG elec-trode with Pt NPs and coating with Nafion. These figures of merit underlines the potential of these sensors for the quantification of physiologically relevant concentrations of DA in biological fluids, paving the way for the development of hybrid electrochemical/optical sensing actuating platforms in a lab-on-fibre configuration, with relevant applications in biomedical engineering. The advantages of this hybrid arrangement include the possi-bility of in-situ counterproofing, extended measuring ranges, photoelectrochemical detection and the probing of inaccessible places. This elegant approach can also provide a simple and cost-effective way to fabricate biomed-ical devices with extended functionality, such as medical optical probes with added electrochemical capabilities, optogenetics combined with local electrochemical detection, among others.
The Concept of “Hypersexuality” in the Boundary Between Physiological and Pathological Sexuality
Authors: Perrotta Giulio
Published: April 2023

Introduction: The concept of hypersexuality belongs to modern parlance, according to a predominantly clinical meaning, understood as a psychological and behavioural alteration as a result of which sexually motivated stimuli are sought in inappropriate ways, often experienced in a way that is not completely satisfactory. Methods: Literature up to February 2023 was reviewed. Results: Forty-two articles were included in the review. Conclusion: Hypersexuality is a potentially clinically relevant condition, consisting of one or more dysfunctional and pathological behaviours of one's sexual sphere and graded according to the severity of impairment of subjective acting out; for this reason, the Perrotta Hypersexuality Global Scale (PH-GS) is suggested, which distinguishes high-functioning forms (pro-active and dynamic hypersexuality) from those of attenuated and corrupted functioning (dysfunctional and pathological hypersexuality of grade I and II). Future research is hoped to address the practical needs of this condition, such as the exact etiopathology, the role of oxytocin in dopaminergic hypotheses (and its ability to attenuate the symptomatology suffered by the patient in terms of manic drive), the best structural and functional personality framing of the subject, and the appropriate therapy to pursue.

Ergogenic Effects of the Combination of Caffeine and New Zealand Blackcurrant Supplements: A Double-Blind Singe-Case Experimental Study
Authors: Zart Sebastian , Dindorf Carlo , Fröhlich Michael
Published: April 2023

The use of isolated supplements to enhance performance is widespread among athletes. The aim of this study was to increase knowledge about the combined effects of caffeine and New Zealand blackcurrant (NZBC) dietary supplements. In this study, two subjects each underwent four phases of four sessions in a double-blind and randomized alternating treatment single-case design. After a 3-week pre-test phase, the supplement combinations of placebo/placebo, caffeine/placebo (5 mg/kg), NZBC/placebo (600 mg), and caffeine/NZBC (5 mg/kg + 600 mg) were taken and weekly performance tests were conducted to examine their effects on relative power (W/kg) during a 20-minute time trial on a bicycle. Data were analyzed descriptively and using the Tau-U calculator from Single Case Research. The ergogenic effect of caffeine was confirmed in both subjects, with increases of 3.3% and 6.5%, while the positive effect of NZBC on performance was only seen in one subject (13.4%). The combination of caffeine and NZBC again increased performance in both subjects (2.2% and 19.2%), but the data only showed an additive effect of the supplements in one subject. Further studies are required to confirm or refute this evidence of the synergistic effects of these supplements.

Irrigation and fertilizer are two essential factors affecting rice root traits and yield. In this respect, a pot experiment was performed at the boro (dry season irrigated) season of 2021-22 in the Department of Agronomy of Bangladesh Agricultural University, Mymensingh, Bangladesh. The variety Binadhan-10 was planted at two irrigation conditions i.e. saturation (S) and continuous flooding (CF); two potassium (K) dose e.g. 65 kg ha-1 (K65) and 98 kg ha-1 (K98) and two nitrogen (N) dose i.e. 140 kg ha-1 (N140) and 210 kg ha-1 (N210). The experiment was laid in split plot design and replicated thrice. The findings confirmed the effectiveness of irrigation, K and N on root number (RN), root length (RL), root volume (RV), leaf area index (LAI), total dry matter (TDM), yield attributes and yield. Considering interaction among irrigation, K and N, S condition with K65 and N140 showed best performance. At 80 DAT, the highest RN (373.00), RL (1700.00 cm), RV (8.90 cm3 hill-1), LAI (4.94) and TDM (25.83 g plant-1) was obtained from this combination. Grain yield (GY) and root traits except root porosity, showed a significant positive association. Grain yield (GY) was highest (27.12 g pot-1) in S condition with K65 and N140.

Published: April 2023

This research is aimed to develop the method for damage degree evaluation in metals and alloys during their deformation and destruction based on acoustic emission (AE) technique. Experimental studies were carried out on tensile specimens of high-strength steel with simultaneous registration of AE signals in tested material. It was shown that the time-dependent AE primary parameters, such as the AE signal maximum amplitudes and AE activity, do not have a clear relationship with the material damage degree. This fact makes it difficult to use standard methods for assessing the damage degree of acoustic signal sources, including defects. It was proposed to use the Kolmogorov-Smirnov criterion to differ the processes of metal plastic deformation and crack propagation during the rupture. The possibility of estimating the material damage degree by high-energy AE hits share was shown. Besides, a particular expression was obtained for evaluating the damage degree for the material under study.
Application of Deep Neural Network in Gearbox Compound Fault Diagnosis
Authors: Zhang Xiangfeng , Jiang Hong , Xu Qinghong , Li Jun
Published: April 2023

To realize the diagnosis of compound faults in gearboxes at different speeds, an "end-to-end" intelligent diagnosis method based on a deep neural network is proposed, named efficiency channel attention-capsule network (ECA-CN). First, the process uses a deep convolutional neural network to extract fault features from the collected raw vibration signals, then embeds the efficient channel attention module to filter important fault features, then uses the capsule network to vectorize the feature space information, and finally calculates the correlation between different levels of capsules by the dynamic routing algorithm to achieve accurate gearbox compound fault diagnosis. The effectiveness of the proposed ECA-CN fault diagnosis method was verified by the composite fault dataset of the 2009 PHM Challenge gearbox, with an average accuracy of 99.63% and a standard deviation of 0.22%. In the comparison experiments with the traditional fault diagnosis method, the average accuracy of the ECA-CN method was improved by 4.62%, and the standard deviation was reduced by 0.58%. The experimental results show that ECA-CN has a more competitive diagnostic performance.
The Perception of Mistakes Driven by Cognitive Biases: An Experimental Study
Authors: Severin Rom
Published: April 2023

This thesis presents findings from an online experiment aimed at evaluating individuals' attitudes towards their own cognitive biases that lead to objective mistakes. In a number of incentivized decision problems, a participant in the experiment might make a mistake and choose a dominated lottery (FOSD lottery), which is likely to result from a particular heuristic or cognitive bias. In this case, she is then confronted with her error under one of two treatments: a confrontation with an explanation only regarding the mistake or one with the addition of the supposed mechanism (bias). Following this explanation, her comfort level with her choice is measured. A bias that acted as a mechanism for the observed error could be considered advantageous (i.e., useful given alternative costs) or disadvantageous (i.e., mostly harmful) in other decision-making scenarios encountered during one's lifetime. Consequently, the perception of cognitive biases is subjective and may vary among decision makers, who may emphasize either the positive or negative aspects of such biases. The proposed methodology allows to determine whether these biases are perceived as useful rules of thumb, despite leading to a dominated lottery choice in that particular context, or unfavorable.Results revealed significant differences between the two treatments and across five different decision problems. Interestingly, the results showed that in only 60% of the cases, the participants felt uneasy about their mistakes. In the remaining instances, the participants demonstrated either indifference or a sense of comfort with their choice of a dominated lottery. The net effect of providing information on the cognitive biases that presumably lead to the mistakes, measured as the difference between treatments, revealed a negative perception of the mechanism behind the error in one problem, contentment with the mechanism for another, and no significant effect for the remaining biases.
Climate Change Perception and Vulnerability Assessment of the Farming Communities in the Wettest Parts of Ethiopia
Authors: Gemeda Dessalegn Obsi , Dadi Diriba Korecha , Garedew Weyessa
Published: April 2023

This study assesses the perception and vulnerability of the farming communities to climate change in the southwestern parts of Ethiopia. Data were collected from 442 households in four districts: Jimma Arjo, Bako Tibe, Chewaka, and Sekoru. The vulnerability of the farming communities was assessed using the households’ livelihood vulnerability index. A total of 40 indicators were applied to calculate household livelihood vulnera-bility to climate change, which were categorized into five major capitals: natural, social, financial, physical, and human. The household percep-tions of climate change results showed that there existed a statistically significant relationship between climate change perceptions and changes in rainfall pattern (75.6%, p<0.001), temperature pattern (69.7%, p<0.001), drought (41.6%, p=0.016), flood (44.1%, p=0.000), and occurrence of early (53.2%, p<0.001) and late rain (55.9%, p<0.001). The results showed that households in Sekoru district were the most vulnerable (0.61), while Jimma Arjo district were less vulnerable (0.47) to the effect of climate change. The vulnerability of the households in the study areas is mainly related to the occurrence of drought, lack of much-needed infrastructure facilities and weak institutional support. Links with the financial organization are also lacking among the household. The findings of this study will support policymakers to design climate change adap-tation strategies to combat climate change impacts. To support disaster risk management on the one hand and increase the resilience of vulnera-ble societies to climate change on the other hand, we recommend a detailed assessment in the remaining districts of the region.
Fast-Convergence Reinforcement Learning for Routing in LEO Satellite Networks
Authors: Ding Zhaolong , Liu Huijie , Tian Feng , Yang Zijian , Wang Nan
Published: April 2023

Fast convergence routing is an important issue for LEO constellation network, due to its dynamical topology changing and time varying transmission requests. Most of existing research focus on the OSPF routing algorithm, which cannot handle the frequently links state changing of network. In this paper, we propose a Fast-Convergence Reinforcement Learning Satellite Routing Algorithm (FRL-SR) for LEO satellite networks, in which the satellite gets the network links status fast and adjusts its routing strategy. In FRL-SR, each satellite node is regarded as an agent. The agent selects the port for packet forwarding according to its own routing policy. When the satellite network state changes, agent would send ’hello’ packets to the neighbor node to update the neighbor node’s routing policy. Compared with traditional reinforcement learning, FRL-SR can perceive network information faster, and then converge faster. Also, FRL-SR can mask the dynamics of satellite network topology and adaptively adjust the forwarding strategy according to the link state. Various simulation is constructed, the results show that the proposed FRL-SR algorithm out performance the Dijkstra algorithm in performance of average delay, packet arriving ratio, network load balance.

The activity of the Ukrainian enterprise "Stalkonstruktsia" LLC is characterized. It was determined that during 2019-2021, the company's balance sheet is completely liquid, which indicates a sufficient amount of funds to repay current liabilities. The indicators of the business activity of "Stalkonstruktsia" LLC in 2019-2021 positively characterize the company's activity, namely, the company uses its own capital effectively, we observe an increase in the turnover rate of stocks, finished products, accounts payable and an increase in the efficiency of their use, which is positively reflected in the business activity of the company. It was concluded that the enterprise needs to use more long-term debt financing in its economic activities, which will increase the return on equity.
PECULIARITIES OF MANAGING THE IMPLEMENTATION OF REGIONAL INNOVATIVE TRANSFORMATIONS
Authors: Serhiі Mekhovych , Alexander Popov , Svitlana Osypova
Published: April 2023

The article examines the problems of innovative transformations of domestic industries in view of the state and attractiveness of the innovative environment, in which the leading place belongs to scientific research. It was noted that among all spheres of activity, it was science that suffered the most significant losses. In Ukraine, there is a tendency to reduce the number of researchers, which leads to a gradual degradation of the scientific potential. The state of technology transfer according to the first, second and third strategic priorities is of concern because this is a real sector of the economy on which the country's competitiveness depends and which needs reengineering transformations in the first place. The concept of technological reengineering in conditions of clustering of the national economy relies on enterprises of the high-tech sector. The science-intensive sector in Ukraine generates GDP at the level of the most backward countries in the world due to too few types of economic activity (FDI) that meet the criteria of high technology. At the same time, its share of added value in output is the largest among other technological sectors. This shows that science produces high-tech and competitive products. The cluster with its system of connections is aimed at creating systems of machines that meet the needs of the market. For modern clusters of knowledge-intensive production, such a task can be accomplished if attention is focused not only on resource provision, but also on various (several) determinants of market demand, which are formed on the types of market activity. It is justified that the cluster with its communication system is aimed at creating machine systems that meet the needs of the market. The combination of all components of the effect has a positive effect on the readiness of firms and organizations to cooperate with cluster structures, and this is a factor of regional development.

Partial weight reduction protocols in cats lead to better weight outcomes, compared with complete protocols, in cats with obesity
Authors: German Alexander J. , Woods-Lee Georgiana R.T. , Biourge Vincent , Flanagan John
Published: April 2023

Background: To date, there have been no studies comparing outcomes of cats with obesity following either complete or partial weight reduction protocols.
Methods: Fifty-eight cats participated in this non-randomized observational cohort study, including 46 (79%) and 12 (21%) that underwent complete or partial weight reduction protocols, respectively. Weight loss outcomes, body composition changes and essential nutrient intake were compared between cats in the two groups.
Results: All cats remained healthy with those undergoing complete weight reduction losing a median (range) of 23% (10-39%) of starting body weight over 294 days (113-967 days), and those undergoing partial restriction losing 25% (10-41%) over 178 days (54-512 days). There were no differences in duration or percentage weight loss between groups, but those that followed a partial weight reduction protocol lost weight at a faster rate (0.81% per week) and required fewer visits (7, 4-19) than those that followed a complete weight reduction protocol (0.61% per week, P=0.028; 11, 4-40 visits, P=0.009). Further, whilst lean mass decreased significantly in cats undergoing complete weight reduction (before 4.20 kg, 2.64-5.72 kg; after 3.90 kg, 2.76-5.24 kg, P<0.001), there was no change in cats undergoing partial weight reduction (before 3.45 kg, 2.79-4.71 kg; after 3.41 kg, 2.90-4.59 kg, P=0.109). Average daily selenium intake was less than NRC AI and RA in 42 cats (72%), and less than FEDIAF recommendation in 33 cats (57%), whilst average daily choline intake was less than NRC MR, NRC RA and FEDIAF recommendations in 22 (38%), 53 (91%) and 51 (88%) cats, respectively. Intakes of phenylalanine/tyrosine and potassium were marginally less than recommendations in a minority (12-14%) of cats, but no other essential nutrient deficiencies were observed, and there were no differences between cats undergoing complete and partial weight reduction.
Conclusion: Partial weight reduction protocols in cats lead to quicker average weight loss, with the possibility that lean tissue loss might be minimized. Such protocols might be more suitable for older cats and those with marked obesity.
Economic, social and environmental impacts of green transition investments in a holistic modelling approach
Authors: Kristkova Zuzana Smeets , Cui David Hao , M'Barek Robert , Boysen-Urban Kirsten , Meijl Hans van , Rokicki Bartlomiej
Published: April 2023

This paper provides novel insights into the economic, social and emission-saving impacts of green energy investments using the computable general equilibrium model MAGNET. MAGNET was extended to include sector-specific investment allocation, investment risk premiums adjustment and technology learning effects to endogenize productivity growth in renewable and bioenergy sectors. In line with the proposals on climate neutrality and the Green Deal, the study simulates an increase in investments in renewable energy and bioeconomy sectors (additional 15% replacement of capital stock) starting in 2025.
It is found that additional green energy investments bring positive GDP, social and emission-saving effects. In the case of aggregate GDP, cumulative deviation from the baseline reaches 1.2% in 2050 for the EU as a whole. We also show that, on average, the investment policy would have a positive impact on bioeconomy sector with 3.2% deviation from the baseline in 2050. However, the impacts across particular countries and industries are very heterogenous. Moreover, the sensitivity analysis shows that without additional funding, negative crowding-out effects may occur in the economy. Still, the negative impact on GDP is limited to the regions with lower efficiency of green investments (e.g., France or Spain).

The goal of this paper is to establish a general fixed point theorem for compact single-valued continuous mapping in Hausdorf p-vector spaces, and the fixed point theorem for upper semicontinuous set-valued mappings in Hausdorf locally p-convex for p in (0, 1]. These new results provide an answer to Schauder conjecture in the affirmative under the setting of general p-vector spaces for compact single-valued continuous, and also give the fixed point theorems for upper semicontinuous set-valued mappings defined on s-convex subsets in Hausdorf locally p-convex spaces, which would be fundamental for nonlinear functional analysis in mathematics, where, s & p in (0, 1].

The increase in violence has created an unprecedented crisis in the Sahel, particularly the Central Sahel, with massive displacement of populations already vulnerable to climatic hazards. This paper aims to propose a mathematical model of the ordinary differential equation system that will reflect the dynamics of terrorism and internal displacement. Sobol's sensitivity analysis of the model's parameters will allow us to make proposals for reducing terrorism. Military actions alone do not contribute effectively for fight against terrorism because they only contribute less than 20\%. Radicalization prevention and de-radicalization strategies must be adopted jointly to effectively reduce the spread of terrorism because they contribute more than 80\% on the fight against terrorism.

Recently, El-Sharkasy et al., El-Sharkasy and Badr have shown that to find the mutations of deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), multiset topology is very much essential. In this article we give the definitions of mixed (1,2)-pre-open (resp. mixed (1,2)-semi-open, mixed (1,2)-α-open, mixed (1,2)β-open) mset via two multiset topologies. Besides, we procure the notions of mixed (1,2)-pre (resp. mixed (1,2)-semi, mixed (1,2)α, mixed (1,2)-β) mset continuity between two M-topological spaces (M,τ 1), (M,τ 2) and an M-topological space (N,σ). A decomposition of these types is investigated. Finally, we prove that every τ 1 -mset continuous function is mixed (1,2)-pre- (resp. mixed (1,2)semi-, mixed (1,2)-α-, mixed (1,2)-β-) mset continuous function.

Published: April 2023

Water transfer projects by open channels or under pressure are among the strategies used globally to address water shortages in arid and semi-arid regions. These plans must be submitted to economic, environmental, and social scrutiny in addition to technical reasons. The environmental-technical assessment of the plans and the ranking of their execution priority may be carried out in different ways. The ability to display and analyze data to aid in decision-making is one of the most significant applications and capabilities of GIS. The finest choice or alternatives might be shown after choosing from a variety of possibilities. Different approaches have been put out to analyze different project criteria, allowing for the integration of technical, environmental, social, and other elements. The analytic hierarchy process (AHP)is a strategic decision-making method that was utilized in this study to determine the optimal path for the water transfer pipeline. In an effort to determine the optimal path for the transmission line, questionnaires were created, weighted with these criteria based on the views of experts, and then the various layers of these criteria were compared to one another using the overlapping approach.

Published: April 2023

Equimomental point mass systems facilitate the definition of the inertial properties of a rigid body and simplify the dynamic analysis of mechanisms and machines. In this work, the equimomental systems of three point-masses of planar rigid bodies are investigated using the concept of pseudo-inertia matrix. It is found that given a planar rigid body, it is always possible to determine an equimomental system of three equal masses located at the vertices of an isosceles triangle. A procedure is presented to determine equimomental systems with different masses, guaranteeing that the masses are positive. It is shown that it is always possible to choose an equimomental system of three point-masses located at the vertices of an isosceles triangle with a prescribed position of one mass. The conditions for prescribing the position of two and three point-masses are also investigated. A first idealized example shows the step-by-step procedure for determining an equimomental system of three point-masses of a planar rigid body. The proposed model is applied to a symmetric connecting rod in a second example due to its wide use in combustion engines. A third example shows an equimomental system of an asymmetric bucket of an excavator.
Recommendation method of teaching resources for professional music courses based on knowledge graph
Authors: xin xu
Published: April 2023

There is an abundance of materials for use in professional music courses, but it can be difficult for consumers to quickly and efficiently obtain the specific knowledge they require. Additionally, there is a general lack of data collected on online learning, which renders the recommendation effect of music course resources insufficient. In this study, we use technologies connected to the knowledge graph to the field of online education in order to create a system capable of recommending acceptable educational materials for use in professional music classes. In order to construct a recommendation model using multi-task feature learning, knowledge graphs are embedded within tasks, and high-order connections between latent features and entities are constructed across tasks using cross-compression units. It is possible to achieve success by recommending relevant course materials for individual students based on their requirements, interests, and present skill levels. In terms of its ability to generate suggestions, the proposed knowledge spectrogram-based teaching resource recommendation system for professional music courses outperforms four baseline models on a number of publicly available datasets. This method has some practical utility in the domain of course resource suggestion, and its training time is less than that of the comparison model.
Optimized Fuzzy Inference Based Analytical Process to Determine the Trust Value of Cloud Service Providers
Authors: John Jomina , K John Singh
Published: April 2023

Users can purchase virtualized computer resources using the cloud computing concept, which is a novel and innovative way of computing. It offers numerous advantages for the IT and healthcare industries over traditional methods. However, the widespread adoption of cloud computing across industries is being hampered by a lack of trust between CSUs and CSPs. Since cloud computing offers a wide range of security models and strategies, it is essential to analyse the service using a detailed methodology in order to choose the appropriate cloud service for various user types. Finding a wide variety of comprehensive elements that are both required and sufficient for evaluating any cloud service is vital in order to achieve that. As a result, this study suggested an accurate, optimized fuzzy logic-based trust evaluation model for cloud computing security. Here, we examine how fuzzy logic raises the efficiency of trust evaluation. Trust is assessed using the Quality of Service (QoS) characteristics of Security, Privacy, Dynamicity, Data Integrity, and Performance. The outcomes of a MATLAB simulation demonstrate the viability of the suggested strategy in a cloud setting.

Per- and polyfluoroalkyl substances (PFASs) have attracted worldwide attention due to their high stability, refractory degradation, and bioaccumulation. In this study, 17 PFASs in water, sediment, and fish in the Dongjiang River Basin in southern China were investigated using high-performance liquid chromatography-mass spectrometry. Total PFASs concentrations ranged from 20.83 to 372.8 ng/L in water, from 1.050 to 3.050 ng/g in sediments, and from 12.28 to 117.4 ng/g in fish. Among six species of fish, Oreochromis mossambicus (mean: 68.55 ng/g) had the highest concentration of PFASs, while Tilapia zillii (36.90 ng/g) had the lowest concentration. Perfluorooctanoic acid (PFOA) predominates in water and sediments, while perfluorooctanesulfonic acid (PFOS) predominates in fish. Long-chain perfluorocarboxylates (PFCAs) and perfluorosulfonates (PFSAs) showed higher bioaccumulation, and the field-sourced sediment-water partition coefficients (Kd) and bioaccumulation factors (BAFs) of PFASs increased with the length of perfluorocarbon chains. PFASs concentration in the lower reaches (urban area) of the Dongjiang River is higher than that in the upper and middle reaches (rural area). The calculated hazard ratio (HR) of PFOS and PFOA levels in fish in the Dongjiang River Basin were far less than 1, hence the potential risk to human health was limited.

Published: April 2023

A new deployable warhead-like decoy is proposed in this study. It consists of a rigid deployable skeleton in the center, a cable net system, and a membrane connected to the outer part of the decoy. First, the structural design of the decoy is presented, and its spatial geometry relationship is described. Compared with the existing decoy design, the decoy has high structural stiffness and surface similarity. Furthermore, the large storage ratio ensures that the space it occupies and its weight do not exceed those of the conventional decoy. Then, the structural characteristics and deployment dynamics of the ground and air conditions are analyzed considering the difference between the actual working condition and ground condition. Finally, a prototype is developed to verify the feasibility of the design, and an experimental test is conducted. The test results show that the decoy can be deployed successfully under its passive power and that its structure has good repeatability and surface similarity.
A non-destructive electro-acoustic method to characterize the pull-in voltage of electrostatic actuators

Published: April 2023

For electrostatic actuators the pull-in marks an upper limit for the operation range. Once reached the electrodes come into contact and are shorted without further protection. A non-destructive measurement technique to predict this failure mode is of high interest to allow e.g. fabrication monitoring or reliability studies. To this end we develop a surprisingly simple non-linear lumped parameter model (LPM) for a rather complex electrostatic actuator, designed for an in-ear loudspeaker application. It turns out that a single-degree of freedom model with only one parameter is sufficient. Our key approach is to experimentally determine the free model parameter by analysing harmonic distortions at low frequencies. Harmonic distortions are a very sensitive tool for non-linearities. Our method is suggested by simulations with a 2D stationary finite element method (FEM), demonstrating how the analysis of harmonic distortions for voltages far below the pull-in can predict not only the DC pull-in but also the quasi-static AC pull-in voltages at different working points. The distortion analysis of electrostatic actuator ensembles seems therefore a viable route for their non-destructive characterisation in the non-linear domain.
