Using Cosmological Perturbation Theory to Distinguish between GR and Unimodular Gravity
Authors: Fabris Júlio C. , Alvarenga Marcelo H. , Velten Hermano
Published: July 2023

Unimodular gravity is one of the oldest geometric gravity theories and alternatives to general relativity. Essentially, it is based on the Einstein–Hilbert Lagrangian with an additional constraint on the determinant of the metric. It can be explicitly shown that unimodular gravity can be recast as general relativity in the presence of a cosmological constant. This fact has led to many discussions on the equivalence of both theories at the classical and quantum levels. Here, we present an analysis focused on the classical scalar perturbations around a cosmological background. We focus on the unusual situation in which the typical conservation laws are not adopted. The discussion is extended to the case where a non-minimal coupled scalar field is introduced. We also present a gauge-invariant analysis showing that perturbations in unimodular gravity display instabilities. Our results reinforce that the equivalence is not verified completely at a cosmological perturbative level.

Published: July 2023

The increased complexity of modern systems is calling for an integrated and comprehensive approach to system design and development and, in particular, a shift toward Model-Based Systems Engineering (MBSE) approaches for system design. The requirements that serve as the foundation for these intricate systems are still primarily expressed in Natural Language (NL), which can contain ambiguities and inconsistencies and suffer from a lack of structure that hinders their direct translation into models. The colossal developments in the field of Natural Language Processing (NLP), in general, and Large Language Models (LLMs), in particular, can serve as an enabler for the conversion of NL requirements into machine-readable requirements. Doing so is expected to facilitate their standardization and use in a model-based environment. This paper discusses a two-fold strategy for converting NL requirements into machine-readable requirements using language models. The first approach involves creating a requirements table by extracting information from free-form NL requirements. The second approach consists of an agile methodology that facilitates the identification of boilerplate templates for different types of requirements based on observed linguistic patterns. For this study, three different LLMs are utilized. Two of these models are fine-tuned versions of Bidirectional Encoder Representations from Transformers (BERTs), specifically, aeroBERT-NER and aeroBERT-Classifier, which are trained on annotated aerospace corpora. Another LLM, called flair/chunk-english, is utilized to identify sentence chunks present in NL requirements. All three language models are utilized together to achieve the standardization of requirements. The effectiveness of the methodologies is demonstrated through the semi-automated creation of boilerplates for requirements from Parts 23 and 25 of Title 14 Code of Federal Regulations (CFRs).

Published: July 2023

Due to the high incidence of PRRSV mutation and recombination, PRRSV infection is difficult to prevent and control in China and worldwide. Two species of PRRSV, Betaarterivirus suid 1 (PRRSV-1) and Betaarterivirus suid 2 (PRRSV-2), exist in China, and PRRSV-1 has always received less attention in China. However, the number of PRRSV-1 strains detected in China has increased recently. To date, PRRSV-1 has spread to more than 23 regions in China. Based on the phylogenetic analysis of ORF5 and the whole genome of PRRSV-1, Chinese PRRSV-1 can be divided into at least seven independent subgroups. Among them, BJEU06-1-like has become the mainstream subgroup in some regions of China. This subgroup of strains has a 5-aa (4 + 1) characteristic discontinuous deletion pattern at aa 357~aa 360 and aa 411 in Nsp2. Previous studies have indicated that the pathogenicity of PRRSV-1 in China is mild, but recent studies found that the pathogenicity of PRRSV-1 was enhanced in China. Therefore, the emergence of PRRSV-1 deserves attention, and the prevention and control of PRRSV-1 infection in China should be strengthened. PRRSV infection is usually prevented and controlled by a combination of virus monitoring, biosafety restrictions, herd management measures and vaccination. However, the use of PRRSV-1 vaccines is currently banned in China. Thus, we should strengthen the monitoring of PRRSV-1 and the biosafety management of pig herds in China. In this review, we summarize the prevalence of PRRSV-1 in China and clarify the genomic characteristics, pathogenicity, vaccine status, and prevention and control management system of PRRSV-1 in China. Consequently, the purpose of this review is to provide a basis for further development of prevention and control measures for PRRSV-1.
Monitoring of Groundwater in a Limestone Island Aquifer Using Ambient Seismic Noise

Published: July 2023

The limestone islands of Malta face high levels of water stress due to low rainfall over a small land area and a high population density. We investigate an innovative, cost-effective approach to groundwater monitoring in an island environment by computing auto- and cross-correlations of ambient seismic noise recorded on short-period and broadband seismic stations. While borehole readings give accurate site-specific water level data of the groundwater across the islands, this technique provides a more regional approach to quantitative groundwater monitoring. We perform the moving window cross-spectral method to determine temporal changes in seismic velocity (δv/v). Comparison of the δv/v with groundwater levels from boreholes and precipitation shows comparable patterns. We find that the variations of the δv/v from auto-correlations are more pronounced than the cross-correlation, and that short-period seismic stations are also sensitive. The δv/v signal deteriorates at longer interstation distances, presumably because paths traverse complex geology. We conclude that changes in the groundwater level found beneath very small islands, even as small as 3 km2, can be detected seismically. Low-cost, easy-to-deploy seismic stations can thus act as an additional tool for groundwater monitoring, especially in places with limited natural water reservoirs, like rivers and lakes, and infrastructure.

The article discusses the modern surgical tactics of treatment of differentiated thyroid cancer, with an emphasis on organ-preserving operations. The clinical cases in which preoperative diagnostics was not able to reveal the extent of tumor spread are presented. Non-radical surgical tactics in such situations inevitably leads to repeated surgery that is performed against the background of ongoing cancer progression, in which case the patient may be at a higher risk of recurrence than s/he would be with a timely radical operation and therefore may require further treatment.

The review considers modern cancer vaccines consisting of autologous whole cells, dendritic cells loaded with autologous tumor-specific antigens, or plasmids, which lead to antigen expression and immune activation after repeated exposure. Each vaccination strategy can be supplemented with various immunomodulatory agents. Engineering autologous immunotherapy of tumor cells is an approach to restoring the effector function of T cells. Other tumor-associated antigens (TAAs) are also of interest in ovarian can cer. Adoptive immunotherapy is based on infusion of autologous or allogeneic tumor-targeted immune cells that have been expanded and/or activated exvivo. Adoptive immunotherapy can be based on antigen-dependent (innate immunity, for example, natural killer (NK) and cytokine-induced killer (CIK) cells) or antigen-independent (adaptive immunity, for instance, TILs, chimeric antigen receptor (CAR) T cells) strategies. NK cells can kill tumor cells without prior sensitization and play an important role in tumor immunosuppression. Adoptive T-cell immunotherapy, CAR-T-cell immunotherapy, allows combining antigen specificity through conjugation of a specific antibody with T-cell activating properties in a single fused molecule. CARs bypass the immune mechanism of cancer cell release as they endow T-lymphocytes with cytotoxic effector properties. In order to reduce mortality and improve prognosis, further study and refinement of immunotherapeutic strategies for the treatment of ovarian cancer is required.

Recently, rapeseed has become a popular crop in many countries of the world and the acreage is being expanded annually for its production. The demand for this crop is also explained by the fact that it is cultivated for oil seeds in many regions. Winter rapeseed seeds are in demand for feed purposes, because they produce high-quality presscake and meal for farm animals and poultry. The purpose of the research was to study the infl uence of diff erent seeding rates of winter rapeseed varieties Elvis, Loris and Sarmat and the use of growth stimulants Restart and Moddus to increase productivity, product quality and plant resistance to adverse environmental factors under the conditions of the Central Non–Chernozem region. The infl uence of optimized seed seeding rates, the use of modern growth stimulants on the productivity of adaptive varieties of winter rapeseed was determined, an optimized method of using growth stimulants on various varieties of winter rapeseed was used, which allows to improve plant growth and development, photosynthetic activity, and as a result to increase yields. The lowest prime-cost of gross production of Sarmat variety was formed in the variant with a seeding rate of 1,0 million seeds/ha when using the drug Moddus and was equal to 11,6 thousand rubles/ha or 2,6 thousand rubles/ha was less than Elvis variety and 0,9 thousand rubles/ha less than Loris variety. Thus, the expediency of reducing the seeding rates of winter rapeseed varieties Sarmat, Elvis and Loris from the recommended 2,0 to 1,0 million seeds/ha of germinating grains was confi rmed and the optimal use of growth stimulants in the cultivation of winter rapeseed was revealed.

The purpose of this research is to design a tool to solve a problem where motorcyclists are often distracted by other motorcyclists' lights that go directly to the face/eyes so, that it can result in disruption of visibility at night which is not uncommon to cause accidents. The usual stabilizer consists of 2 servos that are used to move objects vertically and horizontally which are used to stabilize the movement of objects or to direct objects to the desired position such as an optical stabilizer on a cellphone camera or like a CCTV camera that can adjust the direction of the camera's view, stabilizer can also be applied to LED lights or flashlights that are used to direct the lights to the desired position, so if the tool is applied to motorcycle spotlights it can prevent the lights from pointing to the faces of other riders by adjusting the position of the spotlights. The method used in this research is an experimental research method where we will test this stabilizer in several road conditions such as inclines, derivatives, turns, and so on. After that we will compare the results of applying stabilizer technology to motorcycle lights and without using a stabilizer, whether using a stabilizer will reduce the impact of spotlights that directly hit the face/eyes which can interfere with vision or not. The results show that the application of a stabilizer on a motorcycle can reduce the impact of spotlights that directly hit the face/eyes. This is because the stabilizer can adjust the tilt angle of the lamp automatically so that the lamp lighting remains facing the road. So, it can be concluded that the stabilizer on the motorcycle lights can reduce the impact of spotlights that directly hit the face/eyes resulting in impaired vision of other motorists. This research is expected to create a useful tool for motorcyclists to prevent unwanted things from happening.

Characteristics of the carotid intima-media thickness and atherosclerotic plaques of carotid arteries in elderly people with rheumatoid arthritis at University Medical Center Ho Chi Minh City
Authors: Cao Thanh Ngoc , Dang Ngoc Son
Published: July 2023

Background: Rheumatoid arthritis (RA) is a chronic inflammatory disease that has been strongly associated with atherosclerosis. Comprehensive cardiovascular disease (CVD) assessment is advised, which entails screening for asymptomatic atherosclerotic plaques using carotid ultrasound. The objective of this study is to examine the features of carotid ultrasound, including carotid intima-media thickness (cIMT) and carotid plaques (CP), and to compare these characteristics between individuals with RA and control subjects.

Materials and Methods: A cross-sectional study involved 66 participants, including 40 RA patients and 26 controls. Medical history and physical examination were conducted by a rheumatologist, while cIMT and CP were recorded via carotid ultrasound.

Results: cIMT was significantly higher in the RA group compared to the control group (0.94 (0.83 - 1.25) mm vs 0.84 (0.80 - 0.92) mm, p = 0.030) and the prevalence of increased cIMT was found significantly higher in RA-patients than non-RA patients (70.00% vs 38.46%, p = 0.011). Compared to non-RA patients, carotid plaques in the RA group were statistically more prevalent on either side of the carotid artery (left 57.50% vs. 26.92%, p = 0.015; right 67.50% vs 26.92%, p = 0.001) and bilateral CP was over three times more common in RA than controls (55.00% vs 15.38%, p = 0.001). cIMT was correlated with age and body mass index.

Conclusion: The occurrence of subclinical atherosclerosis is higher among patients with RA than in the control participants without RA. Measuring cIMT and CP may be a useful guide to better assess CVD risk in patients with RA and enable clinicians to take interventions promptly.

Published: July 2023

Objectives: This study aimed to investigate the efficacy of in vitro fertilization (IVF) in infertile patients with adenomyosis and to identify relevant factors.

Subjects and methods: Retrospective descriptive study of infertile cases with adenomyosis who received IVF therapy and embryo transfer from November 2013 to October 2022 at the Center for Reproductive Endocrinology and Infertility, Hue University of Medicine and Pharmacy Hospital, excluding cases of oocyte donation or surrogacy. The β-hCG test was examined two weeks following embryo transfer. Then, women with hCG positive test were followed the pregnancy at 6 weeks, 8 weeks, and 12 weeks, and examined some factors that influence the clinical outcome of pregnancy.

Results: Among 61 cycles of IVF treatment for infertile patients with adenomyosis, the average number of retrieved oocytes was 10.9±6.6 oocytes. The percentage of mature oocytes was 82.7%, the fertilization rate was 79.5%, the implantation rate was 16.7%, the clinical pregnancy rate was 19.7%, the miscarriage rate was 6.6%, and the ongoing pregnancy rate was 13.1%. In the group with GnRH agonist administration before embryo transfer, the pregnancy rate was greater than in the group without therapy (29.2% vs. 13.5%), and th e pregnancy rate in the group with > 10 oocytes was higher than in the group with ≤ 10 oocytes (28.0% vs 13.5%). However, these differences were not statistically significant (with p > 0.05). The cut-off point of endometrial thickness on the day of hCG injection, 10.25 mm, had a sensitivity of 58.3%, a specificity of 81.6%, an area under the curve (AUC) of 75.6%, and a p-value of 0.006; the cut-off point of endometrial thickness on the day of embryo transfer, 9.75 mm, had an accuracy of 9.75 mm. sensitivity 75%, specificity 71.4%, AUC 78.50%, p = 0.002 for clinical pregnancy prognosis.

Conclusion: The IVF treatment of infertile patients with adenomyosis remains challenging, and additional research is required to explain the influence of this disorder on IVF outcomes.

Terdapat kebutuhan mendesak untuk mengatasi akumulasi sampah plastik. Bengkalis, suatu daerah di mana volume sampah plastik mencapai 80 meter kubik per hari. Dalam studi ini, reaktor pirolisis dirancang khusus dan dibangun untuk menangani limbah plastik jenis PP. Hasil penelitian menunjukkan bahwa minyak yang dihasilkan dari proses pirolisis ini memiliki nilai kalor bawah (LHV) sebesar 40450 kJ/kg. Meskipun LHV ini lebih rendah dibandingkan dengan nilai LHV bahan bakar premium (43966 kJ/kg), penemuan penting lainnya adalah bahwa pembakaran menggunakan minyak plastik ini jauh lebih bersih dibandingkan dengan premium. Hal ini terbukti dari ruang bakar mesin dan elektroda busi yang lebih bersih saat menggunakan minyak plastik. Hasil pengujian menunjukkan bahwa pada bahan bakar premium, putaran mesin (n) meningkat seiring dengan peningkatan jumlah lampu. Daya (P) yang dihasilkan juga meningkat seiring dengan peningkatan jumlah lampu. Sementara itu, pada bahan bakar minyak plastik, putaran mesin relatif stabil dengan penambahan jumlah lampu. Daya yang dihasilkan juga meningkat seiring dengan peningkatan jumlah lampu. Berdasarkan hasil pengujian, dapat disimpulkan bahwa penerapan teknologi pirolisis dalam mengkonversi limbah plastik menjadi minyak menunjukkan potensi yang baik. Meskipun bahan bakar minyak plastik memiliki putaran mesin yang sedikit lebih tinggi daripada premium, namun minyak plastik mampu menghasilkan daya yang sama atau lebih tinggi dengan torsi yang lebih besar. Hal ini menunjukkan efisiensi pembakaran yang lebih tinggi dan potensi sebagai alternatif bahan bakar yang berkelanjutan dan ramah lingkungan. Oleh karena itu, teknologi pirolisis dapat menjadi solusi efektif dalam pengelolaan limbah plastik dan memberikan alternatif sumber energi baru di tengah kelangkaan bahan bakar minyak.

It is known that women’s image on the front and back covers is crucial for magazines in commercial and business fields; in academic magazines, nevertheless, the image on the outside doesn’t get the same weight since the purpose of these magazines is to inform about the university life that every student, faculty, and administrative staff live day by day. Therefore, the objective of this work is to analyze women’s representation on the front and back covers of the Gaceta Universidad Benemérita Univers idad Autónoma de Puebla (BUAP’s gazette) from 2012 to 2018. This was determined to identify the identit y changes that these images have undergone based on institutional contexts. The chosen method to come to this was a semiotic model based on the proposal of Morris and Vilches retaking the syntactic and semantic dimensions to identify the identity elements of the female student. As a result of this analysis, the following categories emerged to reinforce the image of college women in its different facets: women entering the university; women in university spaces; women in academic activities; and women in sports activities. The analysis of these images leads us to conclude that the college women’s representation is observed in two administrative periods of the rector's office, one of which women were represented from the gender stereotypes assigned to women; nevertheless, the other period shows a change in the representation of college women with more inclusive images influenced by the policies of gender mainstreaming in higher education.

Theoretical reflections and empirical evidence on informal employment: An application using panel data with small within country-variation
Authors: GUILLERMO-PEÓN Sylvia Beatriz , ESTRADA-QUIROZ Liliana
Published: July 2023

This research paper presents some theoretical reflections on the economic sources of the infor ma l economy phenomenon. The discussion is presented under a new approach called the non-retributed factors approach. Under this approach, we consider informal economy, all economic activities in which at least one factor of production is non-retributed or under-retributed. Additionally, using panel data for Latin American countries and other developing countries as well as data for developed countries, we present empirical evidence regarding the impact of physical capital and human capital on infor ma l employment rates. Because these variables show very small variation over time, the small within-group variation characteristic must be considered when choosing the appropriate model estimation technique with panel data. Our findings show that the scarcer the physical and human capital, the higher the informal employment rates will be.

Nowadays, higher education institutions focus their greatest effort and attention on the development of hard skills which are obtained through training, specialization and experience in the professional field, "Technical competences, called hard skills, represented by academic and extra-academic training and professional experience” (Musicco 2018, 126). By giving greater emphasis to the development of hard skills, the development of such indispensable skills for professional performance such as effective communication, motivation, leadership, teamwork, problem solving, decision making, flexibility, emotional intelligence, time management, to name a few, is left aside. With the present research it is intended to verify if through the didactic strategy of role-playing it will be possible to promote the soft skills of leadership, teamwork, decision-making and conflict resolution in the students of the Public Accountant career of the Tecnológico de Estudios Superiores of San Felipe del Progreso. The action research method is mainly used, of a qualitative type and is based on the socio-critical paradigm, for the collection of information instruments such as survey, interview and teacher's diary are used. Finally, the conclusions and recommendations obtained as a result of the execution of the research are presented.

Academic procrastination is a defect in the performance of academic activities that is characterized by postponing until the last-minute tasks that need to be completed. It is of greater interest in universities, since it is a problem that thousands of students struggle with, and it persists even in the postgraduate field with the writing of theses, obtaining low academic performance. Therefore, the learner needs to generate competencies through teacher intervention. Self-regulated learning was implemented as a pedagogical tool with the objective of reducing academic procrastination in students of the Intercultural Health degree from the Intercultural University of the State of Mexico Tepetlixpa campus. The ability to develop self-regulation cannot be transmitted from the teacher to the student as it happens with conceptual content, because it must be built by the individual himself. However, the teacher can provide students with the tools that allow them to discover for themselves the aspects that optimize their own learning process and commitment to the academic activity to be carried out in time and form. Thus, goal setting, planning and reflection are crucial to self-regulated learning. The methodology used is based on the action-research model of reflective and participative character of the teaching staff, the introspective look of the teacher implies human intellection, during a spiral process. The adoption of the qualitative approach allows the application of research techniques such as observation. The presence of academic procrastination had a greater impact in the face of confinement and the adoption of online learning didactics. However, for some students they may represent a problem in their academic performance while, for most of them being aware of their procrastination, they benefit from procrastination by obtaining a good academic performance.
