ESPACIALIDADE AMBIVALENTE:A CONSTITUIÇÃO DA MEMÓRIA COLETIVA NA ESTAÇÃO FERROVIÁRIA DE TARABAI -SP
Authors: Paulino Felipe da Silva , Aguiar Victor Martins de
Published: September 2021

Urban centers play an important role in the process of building and perpetuating collective social memory, becoming responsible for giving identity to certain groups while absorbing signs for individuals and perpetuating themselves as “places of memory”, characteristics that are not enough to inhibit deterioration of time and abandonment. In scenarios similar to these, urban collectives propose to discuss the importance of memory in the construction and activation of historic public spaces, reflections adapted to the old Estação Ferroviária de Tarabai (1954), a fundamental space for the development of the municipality, which after its deactivation was abandoned (1984), even with the implementation of interventions by the government in order to transform it into a leisure space (1992). In this way, the work proposed to observe and understand the dynamics of use, of appropriations carried out locally, emphasizing the importance of collective memory for its activation. For that, direct observations made at the Railway Station were necessary in order to record their spatial practices, with the interpretation of such data through “mind maps”. The observations made on site were complemented with bibliographic and documentary surveys with the purpose of providing theoretical support for surveys carried out on the spot, pondering the importance of collective memory.

The detection, diagnosis, and treatment of prostate cancer depends on the correct determination of the prostate anatomy. In current practice, the prostate segmentation is performed manually by a radiologist, which is extremely time-consuming that demands experience and concentration. Therefore, this paper proposes an automatic method for prostate segmentation on 3D magnetic resonance imaging scans using a superpixel technique, phylogenetic indexes, and an optimized XGBoost algorithm. The proposed method has been evaluated on the Prostate 3T and PROMISE12 databases presenting a dice similarity coefﬁcient of 84.48% and a volumetric similarity of 95.91%, demonstrating the high-performance potential of the proposed method.

Published: September 2021

Newborns (NBs) feel pain and the more premature they are, the more immature are their pain attenuation system. Facial expression recognition is a non-invasive method to identify and evaluate their feelings, since it provides relevant information about pain and the NB's emotional state, allowing discrimination with non-painful stimuli. In this context, this study proposes to use Kendall's correlation coefﬁcient to quantitatively compare the relevance between the facial areas reported in literature to evaluate the NB's pain with the facial areas observed by health professionals and lay people, through eyetracking, when performing the visual pain assessment task on the NBs' facial images. The results showed that the visual perception of adults does not agree with the facial areas proposed by the literature for pain analysis. In addition, the results suggest that health professionals present a distinct perception when compared to the perception presented by non-health professionals. We believe that such results might help to improve pain assessment carried out clinically.

Authors: Simões Maria Denise , Neves Ana Régia de M.
Published: September 2021

Em 11 de março de 2020, a Organização Mundial da Saúde (OMS) declarou o estado de pandemia de Covid-19. No Brasil, os sistemas oﬁciais responsáveis pela visibilidade dos dados da pandemia não são integrados, o que diﬁculta o cruzamento de dados e prejudica a investigação do cenário da Covid-19 em cada região. O processo de mineração de texto em mídias sociais está sendo utilizado para deteção e monitoramento de doenças. Nesse contexto, o objetivo deste artigo é realizar uma mineração de texto na rede social Twitter, a ﬁm de analisar a tendência epidemiológica de uma série temporal dos dados sobre Covid-19 no Brasil, testando a hipótese de que o monitoramento das mídias sociais pode auxiliar na detecção de epidemias. Os resultados quantitativos conﬁrmam a hipótese levantada quando comparados aos dados dos agentes oﬁciais notiﬁcadores.

Published: September 2021

A sepse é uma síndrome que acomete milhões de pessoas a cada ano causando aproximadamente 20% das mortes no mundo. O reconhecimento precoce dos sintomas de sepse possibilita o início do tratamento adequado a tempo de proporcionar melhores desfechos para os pacientes. Dessa forma, é relevante desenvolver ferramentas que possibilitem a identiﬁcação da sepse já no ambiente pré-hospitalar como o escore heurístico qSofa. Este artigo apresenta os resultados de testes realizados com modelos de machine learning treinados com dados do primeiro atendimento prestado pelo SAMU. Mesmo com um conjunto de dados restrito, os modelos desenvolvidos apresentaram melhorias na ordem de 7,7% na acurácia e 17,7% na AUC em relação aos resultados do qSofa.

Published: September 2021

A diabetes mellitus pré-existente ou desenvolvida na gestação pode trazer sérios riscos de saúde à gestante e ao bebê, durante todo o ciclo gravídico-puerperal. Nesse sentido, predizer a presença de um dos tipos de diabetes, mesmo antes de seus primeiros sintomas, pode gerar impactos positivos nos sistemas de saúde pública. Este trabalho buscou gerar um modelo de classiﬁcação, utilizando dados da produção ambulatorial do Sistema Único de Saúde, que possa predizer a presença de um dos tipos de diabetes (tipo 1), conforme as características e o histórico de acompanhamento da paciente gestante. O classiﬁcador proposto é capaz de separar as gestantes no sistema de saúde conforme a predisposição à doença, possibilitando gerar um alerta ao sistema, e com isso, direcionar a atenção ao acompanhamento da gestante no âmbito dessa condição de saúde. Os resultados obtidos foram relevantes, apresentando sensibilidade e precisão superiores a 90%. Assim, acredita-se que o modelo proposto pode ser mais um recurso para aprimoramento do sistema.

Published: September 2021

O processo de reparação de ontologias consiste em corrigir e/ou conﬁrmar alinhamentos entre elementos de duas ou mais ontologias. Recursos colaborativos quando aplicados ao processo de reparação de alinhamento de ontologias podem auxiliar os especialistas de domínio, já que eles devem compartilhar conhecimento entre si, melhorando o resultado deste alinhamento. Este trabalho objetiva veriﬁcar os recursos colaborativos do sistema RAOSystem, implementados com base no modelo de colaboração 3C. A análise foi feita em um quasi-experimento com especialistas de domínio. Durante a tarefa, um log de uso do sistema foi coletado, além de um questionário de opinião ao ﬁnal do estudo. Como resultado, os recursos como comentários, aceitação e rejeição de termos foram mais usados. E, aparentemente, alguns participantes colaboraram mais que outros. Assim, foi obtido indícios que os recursos colaborativos contribuíram com a tarefa dos especialistas, embora estudos futuros sobre impactos e implicações ainda precisem ser conduzidos.

Published: September 2021

A colaboração entre os agentes que entrelaçam um ecossistema de inovação demonstra-se uma importante pauta socioeconômica a ser explorada. Dentre as iniciativas que contribuem para tal consolidação, destaca-se a adoção de mapas interativos que, apesar de relevantes, enfrentam uma lacuna empírica quanto à avaliação de elementos associados à Interação Humano-Computador. Diante dessa oportunidade, esta pesquisa objetiva desenvolver e avaliar um mapa interativo e colaborativo explorando o estado do Ceará como estudo de caso que, mesmo reconhecidamente proeminente, ainda não dispõe de iniciativas intrinsecamente open source, de expressão estadual e colaborativa para mapeamento dos seus agentes. Sob um escopo metodológico qualiquantitativo, este trabalho se justiﬁca devido ao seu enquadramento dentro da dinâmica de difusão da inovação. Portanto, além da disponibilização de uma solução open source aderente ao Modelo 4C de Colaboração, este trabalho contribui, de forma pioneira, na condução de um experimento para avaliação empírica de Experiência do Usuário, Usabilidade e Percepção de Valor no contexto de um ecossistema de inovação brasileiro.

Published: September 2021

Sistemas colaborativos apresentam um elevado grau de complexidade devido aos requisitos que devem atender. Entre eles, podemos mencionar o suporte à interoperabilidade social, que utiliza da contextualização social dos usuários a fim de apoiar a interoperabilidade em sistemas colaborativos. Como resultado, é possível enriquecer o contexto das atividades e aumentar a percepção e compreensão dos usuários em relação às atividades realizadas por meio desses sistemas. Contudo, a Interoperabilidade Social ainda é pouco explorada e precisa ser analisada. Assim, o objetivo é realizar um mapeamento sistemático para analisar aspectos da utilização da Interoperabilidade Social no desenvolvimento de sistemas colaborativos.

Published: September 2021

Introduction: The coronavirus 2019 (COVID-19) pandemic has reinforced the importance of facial protection against droplet transmission of diseases. Healthcare workers wear personal protection equipment (PPE), including face shields and masks. Plastic face shields may have advantages over regular medical masks. Although many designs of face shields exist, there is a paucity of evidence regarding the efficacy of shield designs against droplet transmissions. There is even less published evidence comparing various face shields. Due to the urgency of the pandemic and the health and safety of healthcare workers, we aimed to study the efficacy of various face shields against droplet transmission.

Methods: We simulated droplet transmission via coughing using a heavy-duty chemical spray bottle filled with fluorescein. A standard-adult sized mannequin head was used. The mannequin head wore various face shields and was positioned to face the spray bottle at either a 0°, 45°, or 90° angle. The spray bottle was positioned at and sprayed from 30 centimeters (cm), 60 cm, or 90 cm away from the head. These steps were repeated for all face shields used. Control was a mannequin that wore no PPE. A basic mask was also tested. We collected data for particle count, total area of particle distribution, average particle size, and percentage area covered by particles. We analyzed percent covered by particles using a repeated measures mixed-model regression with Tukey-Kramer pairwise comparison.

Results: We used least square means to estimate the percentage area covered by particles. Wearing PPE regardless of the design reduced particle transmission to the mannequin compared to the control. The LCG mask had the lowest square means of 0.06 of all face-shield designs analyzed. Tukey-Kramer pairwise comparison showed that all PPEs had a decrease in particle contamination compared to the control. LCG shield was found to have the least contamination compared to all other masks (P < 0.05).

Conclusion: Results suggest the importance of wearing a protective covering against droplet transmission. The LCG shield was found to decrease facial contamination by droplets the most of any tested protective equipment.
Inpatient Outcomes Following a Return Visit to the Emergency Department: A Nationwide Cohort Study

Published: September 2021

Introduction: Emergency department (ED) revisits are traditionally used to measure potential lapses in emergency care. However, recent studies on in-hospital outcomes following ED revisits have begun to challenge this notion. We aimed to examine inpatient outcomes and resource use among patients who were hospitalized following a return visit to the ED using a national database.

Methods: This was a retrospective cohort study using the National Health Insurance Research Database in Taiwan. One-third of ED visits from 2012–2013 were randomly selected and their subsequent hospitalizations included. We analyzed the inpatient outcomes (mortality and intensive care unit [ICU] admission) and resource use (length of stay [LOS] and costs). Comparisons were made between patients who were hospitalized after a return visit to the ED and those who were hospitalized during the index ED visit.

Results: Of the 3,019,416 index ED visits, 477,326 patients (16%) were directly admitted to the hospital. Among the 2,504,972 patients who were discharged during the index ED visit, 229,059 (9.1%) returned to the ED within three days. Of them, 37,118 (16%) were hospitalized. In multivariable analyses, the inpatient mortality rates and hospital LOS were similar between the two groups. Compared with the direct-admission group, the return-admission group had a lower ICU admission rate (adjusted odds ratio, 0.78; 95% confidence interval [CI], 0.72-0.84), and lower costs (adjusted difference, -5,198 New Taiwan dollars, 95% CI, -6,224 to -4,172).

Conclusion: Patients who were hospitalized after a return visit to the ED had a lower ICU admission rate and lower costs, compared to those who were directly admitted. Our findings suggest that ED revisits do not necessarily translate to poor initial care and that subsequent inpatient outcomes should also be considered for better assessment.

Important performance characteristics in elite grass court tennis: implications for practice
Authors:   , Fitzpatrick Anna
Published: September 2021

Notational analysis has become a valued discipline and well-established tool in many sports. Historically, however, notational analysis and its potential for enhancing competitive performance have not been optimised in tennis, with a lack of grass court tennis research and associated practical applications particularly apparent. Additionally, tennis coaches have shown resistance towards technological advancements and are often unsure how to exploit the performance data available to them. In this thesis, a new, user-friendly data analysis method (Percentage of matches in which the Winner Outscored the Loser, PWOL) is developed and validated, to encourage tennis coaches to engage with notational analysis. The method is applied to Wimbledon match-play data, to identify the important performance characteristics in men’s and women’s elite grass court tennis. Points won of 0-4 shot rally length (i.e. short points) is revealed as the most important, so this characteristic is explored further, revealing the critical importance of serving and returning strategies. Accordingly, players’ tactical serving and returning behaviours are examined using Hawk-Eye ball-tracking data, with results highlighting that players tend to use first serves to put opponents under positional pressure by aiming for lateral areas of the service box, while opting for safer second serve strategies, typically targeting more central areas. Male winning players were also able to use their serves and serve-returns to force opponents out of position more often than losing players, hitting a comparatively higher percentage of serves and serve-returns to lateral areas of the court. Alongside the novel data analysis method, this thesis advances knowledge around the important aspects of grass court tennis match-play and provides insight into how matches are won at Wimbledon. Designed to inform practice, the practical application facilitates coaches aiming to develop evidence-informed practices for players during the grass court season, ensuring their training is representative of match-play. Implications for performance analysts and high-performance centres are also explored, to promote a more interdisciplinary approach to player development.
An encultured imperialism: British travel writing from the post-Napoleonic Atlantic periphery
Authors:   , Burke Steven John
Published: September 2021

This thesis examines two selections of published travel writings produced between 1816 and 1831, analysing the encultured attitudes, beliefs, prejudices, and agendas of eight aspiring careerist white British men as they travelled and served in regions on the Atlantic peripheries of British influence. The theatres in question were the Gold Coast in West Africa and the neighbouring Asante Empire, all encountered under the aegis of official or quasi-official British authority, and the region of New Spain encompassing Venezuela and Columbia in South America, all conducted privately as mercenaries on the part of the revolutionary Patriot cause against Imperial Spain. Whether serving in the uniforms of British state institutions or the Venezuelan Republic, these individuals produced accounts of their experiences that more effectively reflected their encultured British National-Imperial worldview than any objective description of the transitional cultures they encountered. I begin the thesis by exploring the cultural context of their travels and publications, the relationship of these to the wider issues of an emerging British Imperial worldview, and a conceptual definition of encultured imperialism as a form of pre-eminent performative engagement with the wider world. Chapter 1 expands on the backgrounds and motivations of the authors in pursuing their service or adventures, within the context of British domestic understandings of the two theatres they visited. Chapter 2 discusses their use of trends and conventions of engagement with landscape and environment, including their efforts to familiarise the exotic as a step towards imagining its subordination to British knowledge. Chapter 3 considers the authors’ evaluations of human geographies, with the further imperative of subordinating other infrastructural and geographical cultures to a projection of British ‘improvement’. In Chapter 4, the focus turns fully on people and these authors’ uses of established and developing hierarchies of difference including tropes of savagery and civilisation, and emergent concepts of scientific racism. Chapter 5 incorporates the influence of encultured conceptions of gender on human difference to complete the analysis of the exclusionary practices of the authors’ self-confident National-Imperial worldview.
Сремска трговишта у XVIII и првој половини XIX века
Authors: Гавриловић Владан
Published: September 2021

Срем се и данас, као и у ранија времена, налази на важној раскрсници путева на Балканском полуострву и владавина над овом територијом увек је значила предност у односу на друге. Хабзбуршка монархија је, у потпуности, завладала и Сремом, после одлука Пожаревачког мира 1718. године. После тога почиње убрзани развој сремских средина, тзв. трговишта, о којима је реч у овом раду. Упоређивањем различитих пописа с краја XVIII и прве половине XIX века, покушали смо да прикажемо демографску слику сремских средина, које су, у највећој мери насељене, као и данас, српским становништвом. Такође, на основу изнетих података указали смо и на њихов убрзани привредни развој. Примера ради, у оквиру провинцијског (грађанског) дела Срема најубрзанији економски, а и демографски развој, у овом периоду, имала је Рума, чији се број становника увећао за готово једну половину. Исто тако, расла су и развијала се места у Сремској војној граници, пре свих Земун, чије је становништво порасло за непуних двадесет година за једну четвртину.
Стање, проблеми и перспективе инклузивног образовања у време информатизације и дигитализације
Authors: Андрић Александра М. , Добрић Тамара М. , Ковачевић Наташа С.
Published: September 2021

Нова политика инклузивног образовања је донела са собом низ промена, којима ће се осигурати прелазак са хронолошки старијег концепта интегрисања детета у образовање, на фокус креирања „образовања за све“. Такво образовање треба да буде отворено за сву децу и у стању да сваком детету пружи квалитетно образовање, што би значило да су школе оспособљене да приме и образују свако дете, укључујући и децу из осетљивих група било ког порекла и са било којом сметњом у развоју или тешкоћом у учењу. Могућност коју пружа настава организована по инклузивним принципима је веома значајна. Суживот и сарадња деце са сметњама у развоју и деце типичног развоја доводи до тога да деца са сметњама у развоју успевају да стекну нека животна искуства која ће им у каснијем животу бити корисна. Предмет овог рада је инклузија у настави и учењу. Један од мотива за покретање истраживања овог типа огледа се у тежњи ка унапређењу инклузивне образовне праксе. Циљ је теоријски анализирати досадашња истраживања о примени инклузије у наставној пракси, те извести научно утемељене генерализације о стању, проблемима и могућим перспективама инклузивне наставе у доба дигитализације. Посебан циљ овог рада је указати на даље перспективе инклузивног образовања у нашим школама.
Socioekonomski status, desničarska autoritarnost i kontakt kao prediktori socijalnih distanci kod srednjoškolaca u Republici Srpskoj
Authors: Pralica Miloš , Dušanić Srđan , Damjenić Milana
Published: September 2021

U radu ćemo razmatrati neke od novijih argumenata u korist panpsihizma, a naročito argumente koje zastupa Filip Gof, kao i razloge zbog kojih je ovaj pristup ne samo neodrživ, već i neutemeljen. Panpsihizam, kao oblik onto-epistemičkog filozofskog pogleda na svijet, ponovo dobija na zamahu nakon Čalmersovog postavljanja „teškog problema svijesti“ (Chalmers, 1995). Polazeći od toga da fizikalizam i emergentizam ne mogu objasniti pojavu svijesti, novi panpsihizam će dovesti u pitanje otkrića nauke, ne samo neuro-nauke već i same fizike. Kritika koja se na ovakav način upućuje prirodnoj nauci ne predstavlja produktivan doprinos razumijevanju fenomena svijesti, te bismo željeli pokazati da, uprkos svim problemima koji slijede iz razmatranja svijesti, odgovor na to kako je svijest moguća ipak prije može doći iz pravca filozofskih istraživanja koja ozbiljno uzimaju u obzir domete savremene nauke, nego li ovako postavljenog panpsihizma.

The trend of an increasing number of student travellers from the University of the North, the University Centers of Koprivnica and Varaždin also affects the quality of their mobility. The mobility of student-passengers in rail passenger transport is directly related to the quality of service and the inevitable maximum safety aspect, but also to the appropriate railway infrastructure. According to the above, it is necessary to analyse the current state of transport infrastructure and propose activities to increase the mobility of student-passengers. This paper analyses the current status of student-passenger mobility in railway passenger transport, and also analyses the regional features of road and railway transport infrastructure, state road DC-2 and railway R202 Varaždin-Dalj, located between the cities of Varaždin and Koprivnica, with regard to route characteristics and infrastructure facilities. As part of the work, a survey was conducted through questionnaires, and questionnaires were completed by students-travellers of the University of the North.

People must be able to move around to meet their basic needs, but also additional needs that include rest and recreation. The growing trend of urbanization leads to population growth in cities, and thus to an increase in demands on the transport system in cities, with the achievement of sustainable urban mobility as one of the key challenges. Cities worldwide have started to look for solutions which enable transportation linkages, mixed land uses and high-quality services with long – term positive effect on the economy. Today cities are flooded with a range of data, both useful and useless. In that large database, city administration should recognize the importance of processing, analyzing and mathematical-statistical processing. Each city should determine its vision, goals and strategies of transforming itself and developing smart services at basis of collected data and their processing. Future initiatives of a smart city and smart transportation should be focused on creating efficient, environmentally friendly transport, based on interactive solutions for smartphones. There are a lot of applications and technologies that contribute to smart cities. Although technology is evolving every day, there is always room for improvement by using available data, smart management and individual approach to each city, it is possible to achieve an improvement in public transport services, which would also improve the quality of life in urban areas.

In order to continue Moore’s Law, the reducing of power consumption is concerned by many researchers, and the discovery of ferronegative negative capacitance effect (NCE) provides a solution. Strain engineering has been widely studied as an effective means to regulate the physical properties of ferroelectric thin films. But the relevant mechanism of strain to ferroelectric negative capacitance regulation is not clear. Recently, the experimental results have shown that it is possible to stabilize the transient NCE in resistance-ferroelectric networks. In this work, we use the Landau-Khalatnikov theory to study the microscopic domain evolution and the influence of strain and temperature on NCE in a ferroelectric film. It is shown that compressive strain enhances NCE while NCE becomes weaker under a tensile strain. However, a larger compressive strain will give rise to a higher coercive voltage that hinders the NCE from forming. In addition, under a certain strain, the NCE becomes stronger at lower temperature. This work provides the theoretical basis for designing the negative capacitance devices and scaling towards nanoscale dimensions in future.

Since the discovery of symmetric helical interactions in the spin-orbit coupled single-band Hubbard model by Moriya and Kaplan, Shekhtman, Entin, Aharony et al. have successfully used this non-negligible symmetric helical exchange interaction to explain the weak ferromagnetism of La2CuO4. By using the non-Markovian quantum state diffusion method, the quantum discord of non-Markovian dynamics in the spin chain system that has Kaplan–Shekhtman–Entin-Wohlman–Aharony interactions and Dzyaloshinskii-Moriya interactions is studied. The effects of Kaplan–Shekhtman–Entin-Wohlman–Aharony interaction on the quantum discord under different external magnetic fields at zero and finite temperatures are discussed. The results show that the quantum discord in the system can be increased via the increasing of Kaplan–Shekhtman–Entin-Wohlman–Aharony interaction in the case of zero or uniform magnetic field, while the case is opposite under the nonuniform magnetic field. More importantly, the ideal discord state can be obtained by modulating the uniform magnetic field and Kaplan–Shekhtman–Entin-Wohlman–Aharony interaction. Moreover, the Markovian case and the effect of temperature on the quantum discord are also discussed, respectively.

Background

Diabetic retinopathy (DR) is characterized by a gradually progressive alteration in the retinal microvasculature that leads to middle-aged adult acquired persistent blindness. Limited research has been conducted on DR pathogenesis at the gene level. Thus, we aimed to reveal novel key genes that might be associated with DR formation via a bioinformatics analysis.

Methods

The GSE53257 dataset from the Gene Expression Omnibus was downloaded for gene co-expression analysis. We identified significant gene modules via the Weighted Gene Co-expression Network Analysis, which was conducted by the Protein-Protein Interaction (PPI) Network via Cytoscape and from this we screened for key genes and gene sets for particular functional and pathway-specific enrichments. The hub gene expression was verified by real-time PCR in DR rats modeling and an external database.

Results

Two significant gene modules were identified. Significant key genes were predominantly associated with mitochondrial function, fatty acid oxidation and oxidative stress. Among all key genes analyzed, six up-regulated genes (i.e., SLC25A33, NDUFS1, MRPS23, CYB5R1, MECR, and MRPL15) were highly and significantly relevant in the context of DR formation. The PCR results showed that SLC25A33 and NDUFS1 expression were increased in DR rats modeling group.

Conclusion

Gene co-expression network analysis highlights the importance of mitochondria and oxidative stress in the pathophysiology of DR. DR co-expressing gene module was constructed and key genes were identified, and both SLC25A33 and NDUFS1 may serve as potential biomarker and therapeutic target for DR.

As potential molecular targets for developing novel pest management strategies, odorant-binding proteins (OBPs) and chemosensory proteins (CSPs) have been considered to initiate odor recognition in insects. Herein, we investigated the OBPs and CSPs in a major global crop pest (Spodoptera exempta). Using transcriptome analysis, we identified 40 OBPs and 33 CSPs in S. exempta, among which 35 OBPs and 29 CSPs had intact open reading frames. Sequence alignment indicated that 30 OBPs and 23 CSPs completely contained the conserved cysteines. OBPs of lepidopteran insects usually belonged to classical, minus-C, and plus-C groups. However, phylogenetic analyses indicated that we only identified 28 classical and seven minus-C OBPs in S. exempta, suggesting that we might have missed some typical OBPs in lepidopteran insects, probably due to their low expression levels. All of the CSPs from S. exempta clustered with the orthologs of other moths. The identification and expression of the OBPs and CSPs were well studied in insect adults by transcriptional analyses, and herein we used samples at different stages to determine the expression of OBPs and CSPs in S. exempta. Interestingly, our data indicated that several OBPs and CSPs were especially or more highly expressed in larvae or pupae than other stages, including three exclusively (SexeOBP13, SexeOBP16 and SexeCSP23) and six more highly (SexeOBP15, SexeOBP37, SexeCSP4, SexeCSP8, SexeCSP19, and SexeCSP33) expressed in larvae, two exclusively (SexeCSP6 and SexeCSP20) and three more highly (SexeOBP18, SexeCSP17, and SexeCSP26) expressed in pupae. Usually, OBPs and CSPs had both male- and female-biased expression patterns in adult antennae. However, our whole-body data indicated that all highly expressed OBPs and CSPs in adults were male-biased or did not differ, suggesting diverse OBP and CSP functions in insect adults. Besides identifying OBPs and CSPs as well as their expression patterns, these results provide a molecular basis to facilitate functional studies of OBPs and CSPs for exploring novel management strategies to control S. exempta.

Since the middle of the 20th century, plastics have been incorporated into our everyday lives at an exponential rate. In recent years, the negative impacts of plastics, especially as environmental pollutants, have become evident. Marine plastic debris represents a relatively new and increasingly abundant substrate for colonization by microbial organisms, although the full functional potential of these organisms is yet to be uncovered. In the present study, we investigated plastic type and incubation location as drivers of marine bacterial community structure development on plastics, i.e., the Plastisphere, via 16S rRNA amplicon analysis. Four distinct plastic types: high-density polyethylene (HDPE), linear low-density polyethylene (LDPE), polyamide (PA), polymethyl methacrylate (PMMA), and glass-slide controls were incubated for five weeks in the coastal waters of four different biogeographic locations (Cape Verde, Chile, Japan, South Africa) during July and August of 2019. The primary driver of the coastal Plastisphere composition was identified as incubation location, i.e., biogeography, while substrate type did not have a significant effect on bacterial community composition. The bacterial communities were consistently dominated by the classes Alphaproteobacteria, Gammaproteobacteria, and Bacteroidia, irrespective of sampling location or substrate type, however a core bacterial Plastisphere community was not observable at lower taxonomic levels. Overall, this study sheds light on the question of whether bacterial communities on plastic debris are shaped by the physicochemical properties of the substrate they grow on or by the marine environment in which the plastics are immersed. This study enhances the current understanding of biogeographic variability in the Plastisphere by including biofilms from plastics incubated in the previously uncharted Southern Hemisphere.
