Dynamic analysis of the joint movement of the hoisting and slewing mechanisms of a boom crane
Authors: Loveikin Viatcheslav , Romasevych Yuriy , Kadykalo Ivan
Published: February 2024

To increase the productivity of boom cranes, the operation of individual mechanisms is combined. At the same time, dynamic loads on structural elements, drive mechanisms and loads on a flexible suspension increase, which reduces the reliability of crane operation and increases energy losses. Therefore, the research aims to consider the problem of the dynamics of the joint movement of the mechanisms for load slewing and hoisting of a boom crane. To study the dynamics of the joint movement of the mechanisms, the boom system was represented by a mechanical system with 6DOF, where the basic movement of the mechanisms and the oscillatory movement of the structural links with elastic and dissipative properties, as well as the load on a flexible suspension in the plane of crane slewing and hoisting were considered. For such a mechanical system of a crane, the differential equations of the joint motion of the crane slewing and hoisting mechanisms were developed. The obtained equations are a system of the second order nonlinear differential equations, for solving which a numerical method in the form of a computer program was used. Using the developed program, the dynamics of the joint movement of the mechanisms of a jib crane with specific numerical parameters were calculated. Based on the calculations, a dynamic analysis of the joint movement of the mechanisms for slewing and hoisting the load of a jib crane with a hoisting boom was carried out, which revealed high-frequency vibrations of links with elastic and dissipative properties, as well as low-frequency oscillations of the load on a flexible suspension. The greatest impact of oscillations is observed during the start-up of mechanisms, where high-frequency oscillations dampen during the transient process, and low-frequency oscillations dampen over a fairly significant period. To improve the dynamic properties of the mechanisms for turning and hoisting a load during their joint movement, it is proposed to optimise the mode of movement in the areas of transient processes (start-up, braking). The research results can be used in the development and operation of cranes in mechanical engineering, construction, and other industries

Authors: Nizar Muhammad , Daljono Daljono
Published: February 2024

This research starts at the root of the problem of investor irrationality in the capital market. A series of studies in the last decade show that investors tend to behave irrationally, and phenomena or anomalies are repeatedly found in the capital market or financial markets that are not in line with standard/traditional finance theory or conventional/orthodox economics theory. This research aims to determine the impact of availability bias, representative bias, and fear of missing out (FOMO) on investment decisions and investment performance, and to find out that FOMO can act as a mediating variable between these relationships. The population in this study were all investors who traded in the Indonesian capital market through brokerage houses in several cities in Indonesia, and the sample size was 116 respondents, using a purposive sampling technique. The data used is primary data, data collection techniques use questionnaires. Structural Equation Modeling (SEM) data analysis technique with the SmartPLS analysis tool. The research results show that availability bias has a positive and significant impact on investment decisions and investment performance. Representative bias has a negative and insignificant impact on investment decisions, but representative bias has a positive and significant impact on investment performance. FOMO has a positive and significant impact on investment decisions and investment performance. Availability bias and representative bias have a positive and significant impact on FOMO. FOMO partially mediates the relationship between availability bias towards investment decisions and investment performance, then representative bias towards investment performance, but FOMO fully mediates the relationship between representative bias towards investment decisions. The results of this research would contribute to the development of knowledge about behavioral finance and have theoretical and policy implications for Indonesian retail investors.  Keywords: Availability Bias, Representative Bias, Fear of Missing Out (FOMO), Investment Decisions, and Investment Performance

Published: February 2024

The study compares the active substance alverine citrate from three commercial sources in order to demonstrate polymorphic forms using the XRPD, SEM, and ATR-FTIR techniques. Based on the solubility tests of alverine citrate, a hard capsule was prepared with the highest possible dose of the active substance. The release profiles of alverine citrate and its stability were also investigated. XRPD and ATR-FTIR analysis shows that all alverine citrate samples (despite differences in the synthesis process) are in the same polymorphic Form I. Scanning electron micrographs of alverine citrate from each manufacturer show differences in morphology (texture). The solubility studies confirmed the complete solubility of the highest dose of alverine citrate in media with a pH of 1.2-6.8. The release studies show that the release of the active substance, regardless of the manufacturer type, meets the immediate release requirement. Accelerated stability studies confirm the stability of the alverine citrate from selected manufacturers. As a result, the manufacturer of the final medicinal product may allow their inter-changeability during production without compromising the safety or efficacy of the medicinal product.

Dear Editor,
In our subsequent study after the receipt of the article, it was found that the P84Ms carrier had certain cytotoxicity. As can be seen from the Figure 1 and Figure 2, compared with the cells in the control group, after incubation with different prepare preparations, the single carrier group Micelles-Blank and Mixed Micelles-Blank could inhibit the growth of the cells. However, the cytotoxicity data in the paper did not set Micelles-Blank and Mixed Micelles-Blank groups, which was also an oversight of our design at that time. Hence it is hard to say whether the therapeutic effect of the preparation is due to the toxicity of the carrier or the therapeutic effect of the drug in this article Therefore, the statement in the article that the carrier is safe and effective may be wrong. So the article needs to be withdrawn, and we will further modify the carrier in the future to reduce its toxicity.

Based on the analysis of external and internal environment factors, a diagnosis of the stage of development of the Russian market (industry) in the context of the key criteria of periodization was made, the stages of development of the agricultural UAV market in the Russian Federation were determined. The identified asymmetry in the stage of market development determines most of the market characteristics that distinguish it from the global market and represent a vivid example of oligopoly. Against the background of changes in the external environment, it is concluded that the agricultural unmanned aerial vehicle market in the near future in its development will strive to overcome the stage imbalance and acquire more balanced proportions.
Determination of application boundaries to Giulotto method to during measuring of longitudinal relaxation time in nuclear magnetic flowmeters-relaxometers

Published: February 2024

The method of nuclear magnetic resonance, which is currently the most common in research and control of parameters of condensed matter, and the nuclear magnetic flowmeters-relaxometers that implement this method are described. The features of determining the times of longitudinal and transverse relaxation in nuclear magnetic flowmeters-relaxometers under different flow regimes of the medium in the process of monitoring its parameters have been established. The advantages of using a modulation technique for recording nuclear magnetic signals in flowmeters-relaxometers in comparison with other registration methods are noted. Using various approximations by the Giulotto method from the Bloch equations, a relation was obtained to determine the longitudinal relaxation time from the results of two measurements of the amplitudes of the nuclear magnetic resonance signal or resonant frequencies at different modulation frequencies. It has been experimentally proven that this relationship has a number of restrictions on its application for flowing liquid. These limitations are associated both with the technique of recording nuclear magnetic resonance signals and with the ability to generate such signals at different modulation frequencies of a constant magnetic field, the amplitudes of which differ from each other beyond the measurement error. The reasons that led to this discrepancy in the ratio for determining the time of longitudinal relaxation have been established. The limits of applicability of the obtained relation are found and it is experimentally proven that within these limits this relation can be used for reliable measurements of relaxation constants. Using experimental data, the relationship for determining the longitudinal relaxation time was studied. It has been proven that in a number of cases it is impossible to determine the desired value using the indicated relationship, although nuclear magnetic resonance signals of the current medium are recorded, and the medium has relaxation times. The results obtained make it possible to eliminate errors when using the nuclear magnetic resonance method to study flowing media and solve a number of complex problems in the energy, oil, chemical and pharmaceutical industries.
#Languagemixing on Twitter
Authors:   , Hadour Taous
Published: February 2024

The influence of the English language on the world stage is such that it now constitutes a kind of global Lingua Franca. As such, English has supplanted French as the language of diplomacy, of culture, and of social prestige. This role reversal entails some residual opposition in France, and in consequence, the use of English expressions and vocabulary by French continues to be a controversial subject in France, as it has been for decades. Regulations are still being implemented to control the French language. Nowadays, social media has been an important tool in our society. Twitter has become a popular means of communication used in a variety of fields, such as politics, journalism, and academia. This widely used online platform has an impact on the way people express themselves and is changing language usage worldwide at an unprecedented pace. The language used online reflects the linguistic battle that has been going on for several decades in French society today. In my dissertation, I investigate the factors prompting the use of English and French language mixing on Twitter in France. The use of acronyms, hashtags as well as another language may be used as strategies to reach a wider audience. The need for visibility and audience maximization seem to be important factors for linguistic choice on Twitter. This study enables a deeper understanding of users' linguistic behavior online. The implications are important and allow for a rise in awareness of intercultural and cross-language exchanges.

Published: February 2024

The release of the Next Generation Science Standards (NGSS) in 2013 introduced science standards that are rich in core ideas as well as science and engineering practices. The NGSS views science content and science practice as closely interconnected to each other. The aim of this study is to explore the relationship between students' level of science content and their ability to engage in the practice of scientific argumentation. Specifically, this study teases apart content knowledge into both domain-general and discipline specific knowledge. To this end, this study explores the following research questions. (1) What is the relationship between students' content knowledge and their ability to engage in scientific argumentation? (2) How do the different dimensions of argumentation vary in difficulty? To explore these research questions, factor analysis, Item Response Theory, and Structural Equation Modeling are used. The results indicate the there is a stronger relationship between discipline specific knowledge and argumentation. This study contributes to the understanding of the connection between content knowledge and argumentation has the potential to inform and improve argumentation instruction, which ultimately can provide students with more authentic science experiences in the classroom

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] With the advances in next-generation sequencing technology and significant reduction in sequencing costs, it is now possible to sequence large collections of germplasm in crops for detecting genome-scale genetic variations, and apply the knowledge towards improvements in traits. To facilitate large-scale NGS resequencing data analysis of genomic variations efficiently, we developed a systematic solution using high-performance computing environment, cloud data storage resources and graphics processing unit computing with cutting-edge deep learning approach. The solution contains an integrated and optimized variant calling workflow called 'PGen', a quantitative phenotype prediction model using convolutional neural network and an algorithm to study genome-wide association study based on deep convolutional neural network model. We reviewed and compared studies of statistical and deep learning genomic selection and genome-wide association methods, present our work on thousands of lines of soybean sequencing dataset, summarized ongoing progress of large-scale genome-associated studies and discussed the future work and development.
Modeling gibbs point processes through basic function decompositions
Authors:   , Hassett Christopher
Published: February 2024

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] We consider non-homogeneous pairwise interaction point process models, where the global and local effect functions are modeled using basis function expansions. For data with interaction between points, we use an ordered exponential prior on the interaction coefficients. For data without interaction we use independent normal priors. The basis coefficients are estimated in a Bayesian framework where we use the double Metropolis-Hastings algorithm. The corresponding hyperparameters can be drawn using a Gibbs sampler. The proposed methodology is exemplified through simulation and through locations of waterstriders and locations of forest fires from the waterstriders dataset and the clmfires dataset, respectively, both from the spatstat R package (Baddeley et al., 2015). The model is then extended to allow for the inclusion of covariates. The methodology is illustrated using the location of kidnappings in a selected area in the southern region of Chicago for 2015, where we include as covariate information the American Community Survey 5-year period estimate of median income at the Census tract level.
Functional myology of the primate head and neck with implications for hominin evolution
Authors:   , McGechie Faye
Published: February 2024

[EMBARGOED UNTIL 5/1/2025] The primate nuchal region has been widely cited as reflecting postural and locomotor behaviors. Postural and locomotor reconstructions of fossil primates, particularly fossil hominins, have relied upon untested hypotheses linking nuchal muscle form and function to bony morphologies. This thesis addresses the gap in knowledge of variation in the primate nuchal musculature and its relationship to positional behaviors through the use of gross cadaveric dissections and in silico visualization and quantification of muscle variables. Nuchal muscle mass is best predicted by body size alone across primates. Additionally, in situ attachment sites of the nuchal musculature are similar among closely related taxa rather than among species with similar positional behaviors. Semisuspensory taxa have more dorsoventrally oriented trapezius muscles when compared to closely related but nonsuspensory taxa. Orthograde primates have less powerful longissimus capitis muscles than pronograde primates do. Further, primates that engage in extreme neck rotation demonstrate differentially oriented and more powerful sternocleidomastoid muscles. These combined results, however, do not translate to overall differences in the moment-generating capacity of the nuchal musculature. The main exception is that primates that engage in extreme neck rotation have larger estimates for moments of lateral flexion of the neck when compared to all other taxa. Overall, this study does not support the idea that nuchal muscle function is driven by positional behaviors alone. It further demonstrates the need to consider muscle morphology and function when using a biomechanical framework to interpret the primate fossil record.
National mentality and ethics of a journalist

Published: February 2024

The professional ethics of journalists stands out as a pressing issue in contemporary public opinion. This article delves into the impact of the national mentality on journalists’ ethical norms and positions, as endorsed by global journalistic associations. “Journalistic ethics is a pivotal aspect of a journalist’s work. The in-depth reading, comprehensive understanding, and exploration of this represent one of the significant challenges in Kazakh journalism. This complex issue, often overlooked, remains insufficiently acknowledged in both scholarly and professional domains,” the study thoroughly examines within the context of the national mentality. The research provides a scholarly understanding of the continuity of traditions, customs, life positions, and perspectives of the Kazakh people in today’s national journalism. The investigation scrutinizes the extent to which national manners shape journalistic ethics. Many media outlets have exceeded boundaries to boost viewership or readership, exaggerating with high ratings and disseminating misinformation, thereby shaping a contemporary model of journalistic culture. The authors highlight the challenging conditions for information dissemination influenced by such factors. In the final conclusion, the study establishes that scrutinizing ethical principles in the media aids in predicting developmental processes in the state and society, facilitating the formulation of strategies to transform social communication and media culture into a beneficial channel for society.

This article reviews the mechanisms, factors, and preventive measures of upper limb lymphedema following breast cancer surgery. Methods: Extensive review of recent research literature on factors and prevention of upper limb lymphedema after breast cancer surgery in the past five years, followed by analysis and summary. Conclusion: Postoperative upper limb lymphedema significantly impacts the function and mobility of the affected limb. The formation of upper limb lymphedema is a chronic process, and to date, there is no treatment that can fully restore the affected limb. Therefore, early detection, preventive measures, and the proactive adoption of effective strategies have become a new approach to treatment. By systematically elucidating the mechanisms, factors, and preventive measures of postoperative upper limb lymphedema in breast cancer, adopting effective preventive measures can reduce the occurrence of upper limb lymphedema, alleviate patient suffering, and improve the quality of life.

Murguía cen anos despois
Authors:   Real Academia Galega, Aleixandre Marilar
Published: February 2024

Transcorridos cen anos desde a morte do fundador da Real Academia Galega, a pegada das ideas de Manuel Murguía é aínda visible en como galegas e galegos pensan o país, a identidade galega, en como se pensan a si mesmos. Murguía foi o pensador que construíu o paradigma do celtismo e do rexionalismo, unha personalidade clave na institucionalización da cultura galega que desempeñou tamén un papel importante nas relacións coa colectividade galega en América. A súa é unha vida moi completa que merece ser rescatada e lanzada cara ao futuro. As xornadas coas que a Real Academia Galega quixo conmemorar o centenario do pasamento do que foi o seu primeiro presidente, celebradas o 2, o 9 e o 16 de febreiro de 2023, trataron de revelar a pluralidade e a complexidade da súa figura e da súa obra. As nove contribucións recollidas neste volume poñen o foco sobre Murguía e sobre as institucións, a idea de Galicia e a literatura nacional; compleméntanse ofrecendo distintas facetas do pensamento murguián e abren, asemade, camiños aínda por explorar.

Background: Loss of projection is a very common complaint after nipple reconstruction. In this paper, we present our experience with the use of a novel human cadaver-donor-derived acellular dermal matrix, named MODA (Matrice Omologa Dermica Acellulata) from the Regional Skin Bank to improve and stabilize nipple projection after oncoplastic breast surgery.
Methods: We did a retrospective analysis of patients undergoing nipple reconstruction with local flap and MODA graft after breast reconstruction between February 2019 and May 2021. The analysis was done following the Declaration of Helsinki and was approved by the ethics committee; written consent was sought from all the participants. The main evaluation criterion was nipple projection measurement, performed immediately after surgery, 6 and 12 months postoperatively. The secondary endpoints were complications and patients’ satisfaction.
Results: In this study, 50 patients underwent nipple reconstruction, with 57 reconstructed nipples. All cases except six followed delayed breast reconstruction. The patients were divided into 3 groups, according to the breast reconstructive technique. There were three cases of delayed wound healing and two cases of partial necrosis, but all of the cases healed by secondary intention. Five percent of the patients (3/57 reconstructions) presented more than 60% of nipple projection loss and required another procedure. The other reconstructed nipples maintained an average of over 60% projection after 12 months.
Conclusion: The described technique presents a high success rate associated with low complications. Indeed, it provides the advantages of nipple reconstruction with ADM with low costs, appears safe after radiotherapy, and has similar results when used after different reconstructive techniques.
Axillary Lymph Node Coverage in Breast Cancer Patients Treated with Adjuvant Radiation Using High Tangent Fields Technique: A Single Institution’s Experience

Published: February 2024

Background: The high tangent field (HTF) technique is used to provide radiation coverage of the inferior axillary nodal levels for breast cancer patients when the lower axilla is at risk for micrometastatic disease. Despite its use in clinical practice, there is concern about whether HTF provide sufficient coverage of level I and II axillary nodal regions. The purpose of this study is to quantify and evaluate the coverage of HTF at our institution.
Methods: Patients diagnosed with early invasive breast carcinoma (pT1-2 pN0-1a) who received HTF radiation between January 1st, 2012 and December 31st, 2016 were retrospectively reviewed. Level I and II axillary nodal regions were contoured on each patient’s simulation CT. Dosimetric parameters were re-calculated to evaluate coverage. Statistical analysis was conducted using Mann-Whitney-U method. 
Results: Thirty-seven patients with low-risk breast adenocarcinoma were included. For level I and II, the mean V90% was 94.63% ± 7.60% and 73.33% ± 21.83% respectively. Twenty-nine patients received adequate V90% coverage of level I and had a mean level II V90% of 76% ± 18.71% while eight patients who did not receive adequate V90% level I coverage had a mean level II V90% of 63.64% ± 30.22%. The median level II V90% of patients receiving adequate and inadequate level I V90% was 77.74% and 71.11% respectively; the difference was not statistically significant (P = 0.33).
Conclusion: HTF provides adequate coverage for level I nodes, but inadequate coverage for level II. Contouring nodal volumes may assist field placement and improve nodal volume coverage.
