The Declaration of the Rights of Man and of the Citizen of 1789 recognizes basic rights, including the right to life, liberty, security, equality, property and the expression of ideas and opinions through the press or any other medium. This would mark the starting point of freedom of expression, which today is complemented by the use of technology and the Internet. Since this historical event, people’s rights have evolved, and new rights have arisen in accordance with the times, such as the right to express oneself and to be communicated through the Internet, using appropriate devices. In 2013, the Mexican Constitution was reformed to recognize the right of people to be communicated, including access to the internet, in Articles 6 and 7. According to the United Nations Resolution of July 2, 2018 on the promotion and protection of all human rights—civil, political, cultural, economic and social rights, including the right to development—, the human right to have access to the internet is mentioned; however, Mexico had already included it in its regulatory framework since 2011. The final section of this paper focuses on the study of the use of technology and the Internet in the current regulations, as well as on the challenges faced by civil and family procedural law with the entry into force of the new Code of 2023.

This article presents the design and analysis of the reconfigurable reflectarray structure based on metamaterials for Sub-6 GHz 5G applications. The proposed reflectarray structure is printed on a 1 mm-thick FR4 dielectric substrate with a total size of 180 × 180 mm2. The reflectarray consists of 144 unit cells, each with dimensions of 15 × 15 × 1 mm3. The unit cell design is a single layer based on multi-concentric square rings. A single layer is used to achieve a negative constitutive parameter (-εr or -μr); multiple rings of different sizes provide a wide reflection bandwidth to improve the performance of the reflective surface. Dual bands of reflection were observed. The first band of reflection is 2.6 GHz, 1.98-4.6 GHz, and the second band is 1.71 GHz, 7.41-9.1 GHz. Two PIN diodes are used in each unit cell of the reflectarray structure for reconfigurable behavior achievement. Depending on the diode states, the phase distribution across the proposed reflectarray structure changes, and the incident waves are reflected at different angles. This work conducted a comprehensive analysis of S-parameters, constitutive parameters, and refractive index, based on full-wave analysis. The CST Microwave Studio software package was used to design and analyze the proposed design structures. A good agreement was observed between the measurement results and those from the simulation.

Objective: This study aimed to assess the effect of increased omega-3 consumption on fertilization rates and the probability of women getting pregnant. This study is needed because different perspectives exist regarding the use of omega-3 fatty acids in enhancing fertility among women with reproductive issues, and information for those planning a spontaneous pregnancy is limited. Methods: PubMed, Clinical Trials, CINAHL/EBSCO, Medline Complete, Cochrane Library, and Google Scholar were searched for articles published until April 2021, and the search was limited to articles in English language. The search strategy included the following key words: “in-vitro fertilization (IVF),” “intracytoplasmic sperm injection techniques (ICSI),” “pregnancy,” “omega-3 fatty acid,” “alpha-linolenic acid,” “eicosapentaenoic acid,” “docosahexaenoic acid,” “n-3 polyunsaturated fatty acid,” and “fish oil and seafood.” Studies reporting female fertility occurring naturally or IVF/ICSI concurrent with omega-3 intake were included. Retrospective studies, studies including postmenopausal women, and unevenly matched control and study groups were excluded. To assess bias, we used the Cochrane Handbook for Systematic Reviews of Interventions, version 5.1.0. To synthesize the findings from the studies included in this review, a meta-analysis was conducted using calculated or extracted odds ratios (OR) of clinical pregnancies and fertilization rates for each group in each study. Results: We included six trials involving 1789 women who received fertility treatment, four trials involving 2607 women who conceived naturally, and three trials involving 1725 oocytes for fertility rates. Aggregated ORs for the effects of omega-3 on pregnancies were 1.74, 1.36, and 2.14 for women who received fertility treatment, those who conceived naturally, and fertilization rate, respectively. All these results were significant (p ≤ 0.01), although they had high heterogeneity I2>68 %. Conclusion: This systematic review and meta-analysis suggest that omega-3 intake significantly improves women's pregnancy and fertilization rates; however, the high heterogeneity in this review somewhat limits its interpretation. Therefore, further prospective randomized studies are necessary to better understand this relationship.

To examine the regulatory mechanisms of oligopeptides derived from soft-shelled turtle protein on tubulin activity in tumor cells, this study employed three specific oligopeptides D-7-A, E-7-W, and G-8-V obtained from soft-shelled turtle protein. The objective was to assess their impact on tubulin polymerization and depolymerization, investigate their interaction with tubulin, and elucidate the mechanisms induce apoptosis in tumor cells. The results showed that the three oligopeptides exhibited similarities to vincristine and acted as inhibitors of tubulin polymerization, their respective IC50 values was 3.72, 5.01, and 5.95 µmol/L. Furthermore, the molecular docking analysis revealed that D-7-A interacted with the active center of α-tubulin 4X1I, specifically binding to Ser178 and Thr179. The active center of E-7-W was found to be bound by Gln15, Thr225, Tyr224, Tyr210 and Arg214. Similarly, G-8-V was observed to bind to Gln11, Ser178 and Asp329 at the active center, exerting a significant impact on α-tubulin. The results of cell experiments showed that D-7-A, E-7-W and G-8-V had dose-dependent inhibitory effects on A549 cells, with IC50 values of 2003±72, 1877±102 and 1789±137 μmol/L, respectively. The G-8-V exhibited the most potent inhibitory effect on A549 cells, leading to the induction of apoptosis. Moreover, the apoptosis rate demonstrated a significant increase with prolonged drug treatment time. The underlying mechanism of action involved the inhibition of tubulin polymerization and the induction of apoptosis by perturbing the valence bond of α-tubulin.

Recognising and meeting the social and emotional wellbeing needs of LGBTQIA+ students is an essential education policy issue globally. Yet, research suggests that this vulnerable group continues to face challenges to their ability to feel culturally safe at school. Negative experiences include verbal and physical abuse, and this often results in poor outcomes for students. Certain European countries such as Malta and The Netherlands have demonstrated positive progress towards enacting inclusive policy, while others, including Poland, are known to have made little or no development in this area. This paper provides a policy issue analysis on the current situation in Polish schools while considering the added threat of LGBT+ free zones that have plagued the political landscape and exist as a further barrier to tolerance and empowerment. Following this discourse, recommendations for school communities have been provided for the purpose of establishing safe learning environments for LGBTQIA+ students.

Este artículo explora la noción de inconsciente filosófico propuesta por Althusser a finales de los 60, en el marco de su indagación a propósito de las operaciones de explotación y de apropiación del saber llevadas a cabo por la filosofía tradicional respecto del resto de prácticas sociales. Buscando entender qué significación tiene la categoría de historicidad para Althusser, cotejaremos esta idea con otra similar, basada en el programa teórico del profesor español Juan Carlos Rodríguez, quien trabajó ciertos textos literarios a partir de la existencia de un inconsciente ideológico que definiría el alcance de la subjetividad humana en cada etapa histórica.

It was noticed that the mortality rate of SARS-CoV-2 infection experienced a significant declination in the early stage of the epidemic. We suspect that the sharp deterioration of virus toxicity is related to the deletion of the untranslated region (UTR) of the virus genome. It was found that the genome length of SARS-CoV-2 engaged a significant truncation due to UTR deletion after a mega-sequence analysis. Sequence similarity analysis further indicated that short UTR strains originated from its long UTR ancestors after an irreversible deletion. A good correlation was discovered between genome length and mortality, which demonstrated that the deletion of the virus UTR significantly affected the toxicity of the virus. This correlation was further confirmed in a significance analysis of the genetic influence on the clinical outcomes. The viral genome length of hospitalized patients was significantly more extensive than that of asymptomatic patients. In contrast, the viral genome length of asymptomatic was considerably longer than that of ordinary patients with symptoms. A genome-level mutation scanning was performed to systematically evaluate the influence of mutations at each position on virulence. The results indicated that UTR deletion was the primary driving force in alternating virus virulence in the early evolution. In the end, we proposed a mathematical model to explain why this UTR deletion was not continuous.

A Wi-Fi 6E BAW filter with relative bandwidth of 12% (665 MHz at 5.5 GHz) and good rejection over the whole 6 GHz band (1200 MHz) is reported. The Wi-Fi 6E filters have much wider bandwidth than those of early Wi-Fi 5/6 filters. High coupling coefficient piezoelectric films, highly doped AlScN, are developed to realize such a wide bandwidth. A novel bulk acoustic wave device fabrication process that capable of utilizing wide variety of piezoelectric thin films is used to realize such a challenging filter. The resonators fabricated with the material show keff2 of 13.2% and maximum quality factor of 1789.

In 2013, CancerCare Manitoba (CCMB) launched an urgent cancer care clinic (UCC) to meet the needs of individuals diagnosed with cancer experiencing acute complications of cancer or its treatment. This retrospective cohort study compared the characteristics of individuals diagnosed with cancer that visited the UCC to those who visited an emergency department (ED) and determined predictors of use. Multivariable logistic mixed models were run to predict an individual’s likelihood of visiting the UCC or an ED. Scaled Brier scores were calculated to determine how greatly each predictor impacted UCC or ED use. We found that UCC visits increased up to 4 months after eligibility to visit and then decreased. ED visits were highest immediately after eligibility and then decreased. The median number of hours between triage and discharge was 2 h for UCC visits and 9 h for ED visits. Chemotherapy had the strongest association with UCC visits, whereas ED visits prior to diagnosis had the strongest association with ED visits. Variables related to socioeconomic status were less strongly associated with UCC or ED visits. Future studies would be beneficial to planning service delivery and improving clinical outcomes and patient satisfaction.

India has committed to reduce emissions with a goal to increase renewable energy production to 175 gigawatts (GW) by 2022. Achieving this objective will involve rapidly increasing the deployment of solar and wind energy, while at the same time addressing the related challenges of the financing requirements, environment impacts, and power grid integration. Developing energy on lands degraded by human activities rather than placing new infrastructure within natural habitats or areas of high production agriculture would reduce cumulative impacts and minimize land use conflicts. We estimated that converted lands have the potential capacity of 1789 GW across India, which is >10 times the 2022 goals. At the same time, the total land footprint needed to meet India’s 2022 renewable energy target is large, ranging from ~55,000 to 125,000 km2, which is roughly the size of Himachal Pradesh or Chhattisgarh, respectively. If renewable energy is advanced with the singular aim of maximizing resource potential, approximately 6700–11,900 km2 of forest land and 24,100–55,700 km2 of agricultural land could be impacted. Subsidies and incentive programs aimed at promoting low-impact renewable energy deployment and establishing mitigation obligations that raise costs for projects that create land-impacts could improve the public support for renewable energy.

The Historical Varieties of Democracy dataset (Historical V-Dem) contains about 260 indicators, both factual and evaluative, describing various aspects of political regimes and state institutions. The dataset covers 91 polities globally – including most large, sovereign states, as well as some semi-sovereign entities and large colonies – from 1789 to 1920 for many cases. The majority of the indicators come from the Varieties of Democracy dataset, which covers 1900 to the present – together these two datasets cover the bulk of ‘modern history’. Historical V-Dem also includes several new indicators, covering features that are pertinent for 19th-century polities. We describe the data, coding process, and different strategies employed in Historical V-Dem to cope with issues of reliability and validity and ensure intertemporal and cross-country comparability. To illustrate the potential uses of the dataset we describe patterns of democratization in the ‘long 19th century’. Finally, we investigate how interstate war relates to subsequent democratization.

We present a temporally fine-grained data set on regimes, defined as the formal and informal rules essential for selecting leaders. The data set comprises more than 2,000 regimes from 197 polities, 1789 to 2016. We highlight how the frequency of breakdowns and particular modes of breakdown have followed cyclical rather than monotonic patterns across modern history. The most common breakdown modes, overall, are coups and incumbent-guided regime transformations. Furthermore, we report robust evidence that low income, slow or negative growth, and intermediate levels of democracy predict a higher likelihood of regime breakdown. Yet, by running change-point analysis we establish that breakdown risk has cycled substantively across periods of modern history, and the aforementioned explanatory factors are more clearly related to breakdown during certain periods. When disaggregating different breakdown modes, low income is related to, for example, breakdown due to popular uprisings, whereas intermediate democracy levels clearly predict coup-induced breakdowns and incumbent-guided transitions.

IEEE802.15.4-time slotted channel hopping (TSCH) is a medium access control (MAC) protocol designed to support wireless device networking, offering high reliability and low power consumption, two features that are desirable in the industrial internet of things (IIoT). The formation of an IEEE802.15.4-TSCH network relies on the periodic transmissions of network advertising frames called enhanced beacons (EB). The scheduling of EB transmissions plays a crucial role both in the joining time and in the power consumption of the nodes. The existence of collisions between EB is an important factor that negatively affects the performance. In the worst case, all the neighboring EB transmissions of a node may collide, a phenomenon which we call a full collision. Most of the EB scheduling methods that have been proposed in the literature are fully or partially based on randomness in order to create the EB transmission schedule. In this paper, we initially show that the randomness can lead to a considerable probability of collisions, and, especially, of full collisions. Subsequently, we propose a novel autonomous EB scheduling method that eliminates collisions using a simple technique that does not increase the power consumption. To the best of our knowledge, our proposed method is the first non-centralized EB scheduling method that fully eliminates collisions, and this is guaranteed even if there are mobile nodes. To evaluate our method, we compare our proposal with recent and state-of-the-art non-centralized network-advertisement scheduling methods. Our evaluation does not consider only fixed topology networks, but also networks with mobile nodes, a scenario which has not been examined before. The results of our simulations demonstrate the superiority of our method in terms of joining time and energy consumption.
