Mechanical Behaviour of Photopolymer Cell-Size Graded Triply Periodic Minimal Surface Structures at Different Deformation Rates.

This study investigates how varying cell size affects the mechanical behaviour of photopolymer Triply Periodic Minimal Surfaces (TPMS) under different deformation rates. Diamond, Gyroid, and Primitive TPMS structures with spatially graded cell sizes were tested. Quasi-static experiments measured boundary forces, representing material behaviour, inertia, and deformation mechanisms. Separate studies explored the base material's behaviour and its response to strain rate, revealing a strength increase with rising strain rate. Ten compression tests identified a critical strain rate of 0.7 s-1 for "Grey Pro" material, indicating a shift in failure susceptibility. X-ray tomography, camera recording, and image correlation techniques observed cell connectivity and non-uniform deformation in TPMS structures. Regions exceeding the critical rate fractured earlier. In Primitive structures, stiffness differences caused collapse after densification of smaller cells at lower rates. The study found increasing collapse initiation stress, plateau stress, densification strain, and specific energy absorption with higher deformation rates below the critical rate for all TPMS structures. However, cell-size graded Primitive structures showed a significant reduction in plateau and specific energy absorption at a 500 mm/min rate.

Variation in Avian Predation Pressure as a Driver for the Diversification of Periodical Cicada Broods.

AbstractPeriodical cicadas live 13 or 17 years underground as nymphs, then emerge in synchrony as adults to reproduce. Developmentally synchronized populations called broods rarely coexist, with one dominant brood locally excluding those that emerge in off years. Twelve modern 17-year cicada broods are believed to have descended from only three ancestral broods following the last glaciation. The mechanisms by which these daughter broods overcame exclusion by the ancestral brood to synchronously emerge in a different year, however, are elusive. Here, we demonstrate that temporal variation in the population density of generalist predators can allow intermittent opportunities for new broods to invade, even though a single brood remains dominant most of the time. We show that this mechanism is consistent, in terms of the type and frequency of brood replacements, with the distribution of periodical cicada broods throughout North America today. Although we investigate one particularly charismatic case study, the mechanisms involved (competitive exclusion, Allee effects, trait variation, predation, and temporal variability) are ubiquitous and could contribute to patterns of species diversity in a range of systems.

50 anos da RBSO, 25 anos do SciELO e 38 anos da ABEC Brasil: contribuições para a ciência aberta / 50 years of RBSO, 25 years of SciELO, and 38 years of ABEC Brasil: contributions to open science

Resumo Para comemorar o cinquentenário da Revista Brasileira de Saúde Ocupacional (RBSO), foi realizado, em fevereiro de 2024, o evento "50 anos da RBSO, 25 anos do SciELO e 38 anos da ABEC Brasil: contribuições para a ciência aberta". Esta nota editorial reporta tal evento, descrevendo brevemente o histórico da revista e das entidades representadas: o projeto Scientific Electronic Library Online (SciELO) e a Associação Brasileira de Editores Científicos (Abec Brasil), assim como seus alcances, seus desafios e suas perspectivas. A ciência aberta foi escolhida como assunto para estimular o debate, por ser um tema relevante e transversal que perpassa as atividades da revista e das entidades. A RBSO segue os princípios do acesso aberto desde sua criação, ainda antes do surgimento do movimento do acesso aberto e do debate em torno da ciência aberta. Mais recentemente, aderiu a outras práticas da ciência aberta, como a aceitação de preprints, o incentivo ao depósito de dados de pesquisa e a adoção de políticas editoriais alinhadas. SciELO e Abec Brasil têm sido importantes catalisadores das iniciativas relacionadas à ciência aberta, visando fortalecer os periódicos e ampliar as colaborações científicas e o compartilhamento do conhecimento científico em benefício da ciência e da sociedade.

Abstract As part of the celebration activities for the fiftieth anniversary of the Brazilian Journal of Occupational Health (RBSO), the event "50 years of RBSO, 25 years of SciELO, and 38 years of ABEC Brasil: contributions to open science" was held in February 2024. This editorial note reports on that event, briefly describing the history of the journal and the entities represented: the Scientific Electronic Library Online (SciELO) project and the Brazilian Association of Scientific Editors (ABEC Brasil), as well as their scopes, challenges, and prospects. Open Science was chosen as the theme to stimulate debate, as it is a relevant and cross-cutting issue that permeates the activities of the journal and the organizations. RBSO has followed the open access principles since its inception, even before the emergence of the open access movement and the debate around open science. More recently, it has adopted other open science practices such as accepting preprints, encouraging research data deposition, and adopting aligned editorial policies. SciELO and ABEC Brasil have been important catalysts for initiatives related to open science, aiming not only to strengthen journals but also to expand scientific collaborations and the sharing of scientific knowledge for the benefit of science and society.

Do adult Magicicada (Hemiptera: Cicadidae) feed? Historical perspectives and evidence from molecular gut content analysis.

The periodical cicadas in the genus Magicicada are remarkable for their unusual life histories and dramatic synchronized emergences every 13 or 17 years. While aspects of their evolution, mating behaviors, and general biology have been well-characterized, there is surprising uncertainty surrounding the feeding habits of the short-lived adult stage. Despite a tentative scientific consensus to the contrary, the perception that adult Magicicada do not feed has persisted among the general public, and recent studies are lacking. We directly investigated the feeding behavior of Magicicada spp. through high-throughput sequencing (HTS)-based dietary analysis of nymphs, freshly molted (teneral) adults, and fully sclerotized adults collected from orchard and wooded habitats during the 2021 emergence of Brood X. Identifiable plant DNA (trnF, ITS amplicons) was successfully recovered from nymphs and adults. No plant DNA was recovered from teneral adults, suggesting that all DNA recovered from sclerotized adults was ingested during the post-teneral adult stage. Both nymphs and adults were found to have ingested a range of woody and herbaceous plants across 17 genera and 14 families. Significantly more plant genera per individual were recovered from adults than from nymphs, likely reflecting the greater mobility of the adult stage. We hypothesize that the demonstrated ingestion of plant sap by Magicicada adults is driven by a need to replace lost water and support specialized bacteriome-dwelling endosymbionts that cicadas depend upon for growth and development, which constitutes true feeding behavior.

Significado de la indexación de la Revista Peruana de Ginecología y Obstetricia a Scopus

La Revista Peruana de Ginecología y Obstetricia (RPGO) ha obtenido su inclusión en la importante base de datos Scopus. En una rápida recopilación de la publicación de la revista, se recuerda la dedicación editorial de sus seis editores, cuatro de los cuales acababan de presidir la Sociedad Peruana de Obstetricia y Ginecología (SPOG). Los momentos iniciales de trabajo editorial fueron realizados manualmente, en máquinas de escribir y visitando la imprenta continuamente, así como a los patrocinadores. El compromiso de los Comités Directivos de SPOG para financiar la publicación y distribución de los ejemplares permitió la gradual indexación a bases de datos locales, regionales e internacionales. Su internalización se amplió desde la publicación de la RPGO en el Open Journal Systems (OJS), sistema informático donde se publica los artículos con puntualidad, calidad, incluyendo sus características editoriales y la Información para los Autores. Ahora la publicación es solo virtual, en español e inglés, con visibilidad e impacto de los artículos desde el inicio de la RPGO en 1955. Con datos actualizados del OJS sobre la RPGO, el número de visitas mensuales a los resúmenes llegan hasta 10 mil y las descargas mensuales de artículos en formato PDF hasta más de 9 mil. Y, en el ámbito de revistas científicas de ginecoobstetricia de América Latina y España en Scopus, destaca el índice h de la RPGO por Google Scholar Metrics, como una de las mejores. Al presente, y frente a los desafíos futuros, la actividad de la RPGO ha sido fortalecida, estableciendo un equipo editorial y herramientas que permiten la ya iniciada profesionalización de los procesos de la actividad editorial.

The Peruvian Journal of Gynecology and Obstetrics (RPGO, for its acronym in Spanish) has obtained its inclusion in the important Scopus database. A quick review of the journal's publication recalls the editorial dedication of its six editors, four of whom had just recently chaired the Peruvian Society of Obstetrics and Gynecology (SPOG, for its acronym in Spanish). The initial editorial work was carried out manually, on typewriters and continuously visiting the printing press, as well as the sponsors. The commitment of the SPOG Steering Committees to finance the publication and distribution of the issues allowed the gradual indexing to local, regional and international databases. Its internalization was expanded since the publication of the RPGO in the Open Journal Systems (OJS), a computer system where articles are published with punctuality, quality, including their editorial characteristics and the Information for Authors. Now the publication is only virtual, in English and Spanish, with visibility and impact of the articles since the beginning of the RPGO in 1955. With updated OJS data on the RPGO, the number of monthly visits to the abstracts reaches up to 10 thousand and monthly downloads of articles in PDF format reach more than 9 thousand. And, in the field of obstetrics and gynecology scientific journals in Latin America and Spain in Scopus, the h index of the RPGO by Google Scholar Metrics stands out as one of the best. At present, and facing future challenges, the activity of the RPGO has been strengthened, establishing an editorial team and tools that allow the already initiated professionalization of the processes of the editorial activity.

Periodical Cicada Emergences Affect Masting Behavior of Oaks.

AbstractOaks (Quercus spp.) are masting species exhibiting highly variable and synchronized acorn production. We investigated the hypothesis that periodical cicadas (Magicada spp.), well known to have strong effects on the ecosystems in which they occur, affect acorn production of oaks through their xylem feeding habits as nymphs, the oviposition damage they inflict as adults during emergences, or the nutrient pulse resulting from the decomposition of their bodies following breeding. We found negative effects on acorn production during emergence years and the year following emergences and enhanced acorn production 2 years after emergence. We also found evidence indicating a significant effect of cicada emergences on spatial synchrony of acorn production by trees growing within the range of the same cicada brood compared with different broods. These results demonstrate that periodical cicadas act as a trophic environmental "veto" depressing acorn production during and immediately following emergences, after which the nutrient pulse associated with the cicada's demise enhances oak reproduction.

Low-Profile Dual-Polarized Double-Layer Microstrip Antenna for 5G and 5G Wi-Fi.

A dual-polarized double-layer microstrip antenna with a metasurface structure is proposed for 5G and 5G Wi-Fi. A total of 4 modified patches are used for the middle layer structure, and 24 square patches are used for the top layer structure. The double-layer design has achieved -10 dB bandwidths of 64.1% (3.13 GHz~6.08 GHz) and 61.1% (3.18 GHz~5.98 GHz). The dual aperture coupling method is adopted, and the measured port isolation is more than 31 dB. A low profile of 0.096λ0 is obtained (λ0 is the wavelength of 4.58 GHz in the air) for a compact design. Broadside radiation patterns have been realized, and the measured peak gains are 11.1 dBi and 11.3 dBi for two polarizations. The antenna structure and E-field distributions are discussed to clarify its working principle. This dual-polarized double-layer antenna can accommodate 5G and 5G Wi-Fi simultaneously, which can be a competitive candidate for 5G communication systems.

Bioconvection pattern of Euglena under periodical illumination.

Microorganisms respond to environmental conditions and often spontaneously form highly ordered convection patterns. This mechanism has been well-studied from the viewpoint of self-organization. However, environmental conditions in nature are usually dynamic. Naturally, biological systems respond to temporal changes in environmental condition. To elucidate the response mechanisms in such a dynamic environment, we observed the bioconvection pattern of Euglena under periodical changes in illumination. It is known that Euglena shows localized bioconvection patterns under constant homogeneous illumination from the bottom. Periodical changes in light intensity induced two different types of spatiotemporal patterns: alternation of formation and decomposition over a long period and complicated transition of pattern over a short period. Our observations suggest that pattern formation in a periodically changing environment is of fundamental importance to the behavior of biological systems.

Vascular effects of continuous hyperbaric oxygen exposure: experimental outlook.

Hyperbaric oxygen (HBO) treatment aims to restore tissue oxygenation by inhaling 100% oxygen in pressure rooms. Although beneficial effects have been reported with regard to re-oxygenated ischemic tissues, conflicting findings have been presented concerning the paradoxical tissue response following reperfusion and/or the different responses of non-ischemic normal tissues to increased oxygen exposure. The present study sought to experimentally investigate the impact of continuous HBO treatments on normal aortic tissue. New Zealand rabbits were placed in pressure rooms for 90 minutes per day under 2.5 atmospheric pressure and exposed to HBO for 28 days. Normal structural histology was obtained in the control group. Foam cells were detected in the aortic intimae, thickening and undulation were visualized in the endothelium, and localized separations were observed in the tunica media in the study group compared with the control group. Moreover, salient vasa vasorum was detected in the study group via histopathology. These findings suggest that continuous HBO exposures disrupt the normal vascular structure of a healthy aorta.

Histologic findings of Massospora cicadina infection in periodical cicadas (Magicicada septendecim).

Massospora cicadina, an obligate fungal pathogen in the subphylum Entomophthoromycotina (Zoopagomycota), infects periodical cicadas (Magicicada spp.) during their adult emergence and modifies their sexual behavior to maximize fungal spore dissemination. In this study, 7 periodical cicadas from the Brood X emergence in 2021 infected by M. cicadina were histologically examined. In 7 of 7 cicadas, fungal masses replaced the posterior portion of the abdominal cavity, effacing portions of the body wall, reproductive organs, alimentary tract, and fat bodies. No appreciable inflammation was noted at the intersections of the fungal masses and host tissues. Fungal organisms were present in multiple morphologies including protoplasts, hyphal bodies, conidiophores, and mature conidia. Conidia were clustered into eosinophilic membrane-bound packets. These findings help uncover the pathogenesis of M. cicadina by suggesting there is evasion of the host immune response and by providing a more in-depth description of its relationship with Magicicada septendecim than previously documented.

An improved adaptive periodical segment matrix algorithm for ECG denoising based on singular value decomposition.

BACKGROUND: Wearable devices that monitor heart health of cardiac disease patients in real time are in great demand. OBJECTIVE: We propose an algorithm of improved segment periodical matrix construction for irregular electrocardiogram (ECG) signal denoising. METHOD: While splitting the heartbeat based on each RR interval for periodical segments matrix construction, the as-filtered ECG signal is reconstructed by the maximum singular value after a singular value decomposition. RESULTS: The results demonstrate a higher noise reduction effect with lower signal distortions of our methods compared to several singular value decomposition counterpart approaches. CONCLUSION: Our method has great potential to enhance wearable devices diagnosis accuracy by denoising the complex noises such as electromyography artifacts in real-time ECG sensing.

Homenaje a la Revista Médica de Chile en sus 150 años de vida (1872-2022) / A tribute to Revista Médica de Chile on its 150th Anniversary (1872-2022)

Revista Médica de Chile was founded in 1872 by Sociedad Médica de Santiago (currently Chilean Society of Internal Medicine) and it is one out of twenty five medical journals founded during the XIX Century that still remain active. In monthly issues it presents clinical and biomedical research articles, as well as research and position papers dealing with medical education, public health or medical ethics. Special attention receive the impact on health care given by the emergence of new private medical schools in Chile, the relevance of methodologies to assess clinical competences in graduates, the certification of specialty programs and specialists, the appropiate use of simulators in clinical training, telemedicine, organ transplants, and current issues in medical ethics, such as abortions and euthanasia. Institutional and international collaboration in medical research is clearly reflected in recent years. Articles are subjected to external peer review and ICMJE Recommendations are carefully considered throughout the review process. Most articles are published in Spanish but English abstracts are mandatory and a growing number of articles are currently published in English. An Open Access electronic version is published by SciELO. Revista Médica de Chile is indexed in the most important international data bases and it is a member of the ICMJE ruling committee. The long life and prestige of this journal can be considered a testimony of the cultural heritage and progress in Chilean medicine.

[Indexing of the Revista Médica del IMSS]. / La indización de la Revista Médica del IMSS.

The Revista Médica del IMSS faces the challenge of maintaining the visibility of its articles within the science communication process through indexing in bibliographic databases that make the scientific articles published available to readers, thanks to automation and constant development of information search and retrieval systems. Indexing represents the main means by which a reader will consult your articles regardless of their geographic location, their educational specialization, their affiliation, and even their native language. Likewise, it allows the generation of bibliometric indicators, which are used to evaluate scientific production.

La Revista Médica del IMSS enfrenta el reto de mantener la visibilidad de sus artículos dentro del proceso de comunicación de la ciencia a través de la indización en bases de datos bibliográficas, las cuales ponen al alcance de los lectores los artículos científicos que publica gracias a la automatización y desarrollo constante de los sistemas de búsqueda y recuperación de información. La indización representa el principal medio por el cual un lector consultará sus artículos, independientemente de su ubicación geográfica, la especialización de su formación, su afiliación e, incluso, su idioma natal. Así también, permite la generación de indicadores bibliométricos, los cuales son usados para evaluar la producción científica.

O Lazareto da Jurujuba na imprensa do Rio de Janeiro oitocentista: "logar mais proprio para estender redes de pescarias que para fundar-se um tal estabelecimento" / The Lazarette of Jurujuba in the nineteenth-century Rio de Janeiro press: "a better place to spread fishing nets than to found such an establishment"

Resumo Na segunda metade do século XIX, o periodismo expandiu-se e alcançou grande variedade temática e de público, e era constituído pelos jornais diários, que se dedicavam especialmente ao cotidiano da cidade, e pelas revistas científico-literárias, que veiculavam textos de temáticas diversas, como literatura, biografia, ciências e educação. Nas páginas dos inúmeros periódicos que circulavam no Rio de Janeiro, tanto dos chamados jornais diários quanto dos periódicos científico-literários, evidenciou-se grande interesse pelas temáticas da higiene, da salubridade, da epidemia de febre amarela, das medidas higiênicas e da atuação dos médicos. Entre as medidas sanitárias adotadas, foi instalado em 1º de janeiro de 1851, por orientação de Francisco de Paula Cândido, presidente da Junta de Higiene Pública, um lazareto para cerca de 30 enfermos em uma casa alugada na península do Caju, no Saco da Jurujuba, em Niterói, na província do Rio de Janeiro, e então denominado Lazareto da Jurujuba. Buscamos neste estudo analisar o conteúdo de matérias e comunicados sobre as condições e medidas sanitárias do Rio de Janeiro, especialmente sobre a criação do Lazareto da Jurujuba, publicados nos jornais diários e na imprensa não especializada.

Abstract In the second half of the nineteenth century, the press expanded and reached a wide range of themes and audiences. It consisted of daily newspapers, which were especially dedicated to the daily life of the city, and scientific-literary magazines, which published texts on a wide range of themes, including literature, biography, science, and education. In the pages of the numerous periodicals that circulated around Rio de Janeiro, both the so-called daily newspapers and the scientific-literary periodicals, there was a great interest in the themes of hygiene, salubrity, the yellow fever epidemic, hygiene, and the performance of doctors. Among these sanitation measures, adopted on January 1, 1851, under the guidance of Francisco de Paula Cândido, president of the Junta de Higiene Pública (Public Hygiene Board), a lazarette for about 30 sick people was installed in a rented house on the Caju peninsula, in Saco da Jurujuba, in Niterói, in the province of Rio de Janeiro, and then called Lazareto da Jurujuba (Lazarette of Jurujuba). The present study thus sought to analyze the content of articles and announcements about the sanitary conditions and measures in Rio de Janeiro, especially concerning the creation of the Lazareto da Jurujuba (Lazarette of Jurujuba), published in daily newspapers, and in the non-specialized press.
