Published: October 2020

Amphibian genomes are usually challenging to assemble due to their large genome size and high repeat content. The Limnodynastidae is a family of frogs native to Australia, Tasmania and New Guinea. As an anuran lineage that successfully diversified on the Australian continent, it represents an important lineage in the amphibian tree of life but lacks reference genomes. Here we sequenced and annotated the genome of the eastern banjo frog Limnodynastes dumerilii dumerilii to fill this gap. The total length of the genome assembly is 2.38 Gb with a scaffold N50 of 285.9 kb. We identified 1.21 Gb of non-redundant sequences as repetitive elements and annotated 24,548 protein-coding genes in the assembly. BUSCO assessment indicated that more than 94% of the expected vertebrate genes were present in the genome assembly and the gene set. We anticipate that this annotated genome assembly will advance the future study of anuran phylogeny and amphibian genome evolution.

Nyssa yunnanensis is a deciduous tree species in the family Nyssaceae within the order Cornales. As only eight individual trees and two populations have been recorded in China’s Yunnan province, this species has been listed among China’s national Class I protection species since 1999 and also among 120 PSESP (Plant Species with Extremely Small Populations) in the Implementation Plan of Rescuing and Conserving China’s Plant Species with Extremely Small Populations (PSESP) (2011-2-15). Here, we present the draft genome assembly of N. yunnanensis. Using 10X Genomics linked-reads sequencing data, we carried out the de novo assembly and annotation analysis. The N. yunnanensis genome assembly is 1475 Mb in length, containing 288,519 scaffolds with a scaffold N50 length of 985.59 kb. Within the assembled genome, 799.51 Mb was identified as repetitive elements, accounting for 54.24% of the sequenced genome, and a total of 39,803 protein-coding genes were predicted.
With the genomic characteristics of N. yunnanensis available, our study might facilitate future conservation biology studies to help protect this extremely threatened tree species.

Published: October 2020

Background
The common dragonet, Callionymus lyra, is one of three Callionymus species inhabiting the North Sea. All three species show strong sexual dimorphism. The males show strong morphological differentiation, e.g., species-specific colouration and size relations, while the females of different species have few distinguishing characters. Callionymus belongs to the ‘benthic associated clade’ of the order Syngnathiformes. The ‘benthic associated clade’ so far is not represented by genome data and serves as an important outgroup to understand the morphological transformation in ‘long-snouted’ syngnatiformes such as seahorses and pipefishes.

Findings
Here, we present the chromosome-level genome assembly of C. lyra. We applied Oxford Nanopore Technologies’ long-read sequencing, short-read DNBseq, and proximity-ligation-based scaffolding to generate a high-quality genome assembly. The resulting assembly has a contig N50 of 2.2 Mbp and a scaffold N50 of 26.7 Mbp. The total assembly length is 568.7 Mbp, of which over 538 Mbp were scaffolded into 19 chromosome-length scaffolds. The identification of 94.5% complete BUSCO genes indicates high assembly completeness. Additionally, we sequenced and assembled a multi-tissue transcriptome with a total length of 255.5 Mbp that was used to aid the annotation of the genome assembly. The annotation resulted in 19,849 annotated transcripts and identified a repeat content of 27.7%.

Conclusions
The chromosome-level assembly of C. lyra provides a high-quality reference genome for future population genomic, phylogenomic, and phylogeographic analyses.

A pandemia da Covid-19 vem deixando marcas complexas em todas as áreas da sociedade. No contexto educacional, com a suspensão das aulas em março, alunos, professores e as instituições de ensino precisaram encontrar outra forma de formação escolar. As aulas presenciais foram transferidas para espaços virtuais. Essa situação fez com que instituições elaborassem materiais com sugestões de tecnologias digitais que poderiam ser utilizadas por professores e alunos. Parte desse material tornou-se objeto desta investigação que objetivou identificar, descrever e problematizar quais e como as Tecnologias Digitais da Informação e Comunicação (TDIC) são indicadas para o ensino remoto. Orientadas pela Análise de Conteúdo Categorial, selecionamos entre Lives e Webinars, 12 materiais. A partir delas identificamos as TDIC citadas, que em seguida foram categorizadas em tecnologias para comunicação síncrona, assíncrona ou ambas. Das 80 diferentes tecnologias identificadas, elaboramos a descrição de 14 TDIC que podem ser utilizadas pelos professores e alunos de modo síncrono e assíncrono, apontamos suas finalidades e avançamos com reflexões para o contexto educacional. Mediante análise, reforçamos que as TDIC apresentam características que podem auxiliar no trabalho interativo e participativo dos alunos, mas que também requer uma responsabilidade sobre o modo de ser “aluno e professor” frentes a essas tecnologias. Ponderamos ainda que elas são apenas meios/recursos para viabilizar o desenvolvimento das atividades, a qualidade do ensino e a aprendizagem dos alunos tem estreita relação com vários fatores, entre eles o planejamento didático, objetivos educacionais, metodologias e formas avaliativas, independentemente de serem aulas presenciais ou a distância.
AUTOFORMAÇÃO DOCENTE EM TEMPOS DE PANDEMIA: DA (IM)POSSIBILIDADE DA REINVENÇÃO SEM CUIDADO DE SI
Authors: Feltrin Tascieli , Lampert Batista Natália
Published: October 2020

O que cabe aos educadores em tempos de distanciamento social, reconfiguração das noções de normalidade, presença e temporalidade?  A insurgência de outros cotidianos impele a uma ruptura com a fragmentação da vida e dos espaços em que se desenvolve a vida. A educação, o ensino e demais processos do âmbito da escolarização passam por transformações significativas, levando a uma desconstrução dos parâmetros educativos estabelecidos. Ademais, o cuidado se torna central às relações, inclusive educativas, e, a (auto)formação se torno um eixo de (im)possibilidade se pensada por um viés estritamente tecnológico e mecanicista. Assim, este artigo tem por objetivo refletir sobre o impacto da pandemia na docência com especial atenção à autoformação docente, e à noção de cuidado de si em Foucault (2006), destacando a necessidade de um olhar cuidadoso e crítico para o contexto escolar contemporâneo. Concluísse que as necessidades de reinvenção e fluência tecnológica estabelecidas para educadores e estudantes em todo o território nacional têm assumido um compromisso com a manutenção de códigos que não cabem nesse novo tempo, exigindo o cumprimento de relações puramente burocráticas em detrimento de uma abertura de possibilidade ao novo, ao pensar uma educação que produza sujeitos mais sensíveis ao sofrimento humano, cuidadosos com a ciência e com a preservação do humano nas relações.

Published: October 2020

The monasteries of the Kaluga province present diverse architectural ensembles with complex internal dynamics making it impossible to evaluate all the variety of their forms against uniform criteria. The evolution of a monastery complex sometimes could last several centuries, and therefore their architectures and compositions rarely pertain to a single specific style. When considered as fully-formed architectural developments, these monasteries reveal various common typological features in their construction, layout and composition, determined by both their functional purpose and symbolic interpretation of the monastery ensemble.

Scientific specialties in Green Chemistry
Authors: Marcelino Leonardo Victor , Pinto Adilson Luiz , Marques Carlos Alberto
Published: October 2020

Objective. This paper presents an overview of Green Chemistry research from 1990 to 2017, identifying its specialties, comparing their relative importance, and inferring emergent trends.
Design/Methodology/Approach. Co-citation analysis of 14,142 documents retrieved in Web of Science by CiteSpace software, using network analysis to describe research fronts by clustering, their relevance by clusters indicators, and emergence by citation burstiness.
Results/Discussion. Sixteen clusters were found and then grouped into six big specialties. Some specialties are more persistent and general (e.g. GC Characterization, Metal Catalysis, and Microwave Activation) and others are more recent and focused (e.g. Deep Eutectic Solvents). Mechanochemical and Photochemistry are emergent trends in Green Chemistry.
Conclusions. This paper presents a more quantitative/objective panorama of GC research, comparing the relevance of research fronts inside the field, and helping future researchers and decision-makers in further developments of GC. CiteSpace showed some limitations in clustering. Data collection was hurdled by changes in the Keyword Plus algorithm in Web of Science and by the lack of authors keywords in main journals of the field. Although large, the dataset was restricted to the Web of Science database.
Originality/Value. To the best of our knowledge, this is the first quantitative analysis of research specialties of GC. It advances past peer evaluation of the field by using indicators and metrics to describe the emergence, extension, and decay of specialties.
An idealized model sensitivity study on Dead Sea desertification with a focus on the impact on convection
Authors: Khodayar Samiro , Hoerner Johannes
Published: October 2020

Abstract. The Dead Sea desertification-threatened region is affected by continual lake
level decline and occasional but life-endangering flash floods. Climate
change has aggravated such issues in the past decades. In this study, the
impact on local conditions leading to heavy precipitation from the changing
conditions of the Dead Sea is investigated. Idealized sensitivity
simulations with the high-resolution COSMO-CLM (COnsortium for Small-scale MOdelling and Climate Limited-area Modelling) and several numerical weather prediction (NWP) runs on an
event timescale are performed on the Dead Sea area. The simulations are
idealized in the sense that the Dead Sea model representation does not accurately
represent the real conditions but those given by an external dataset. A
reference or Dead Sea simulation covering the 2003–2013 period and a twin
sensitivity or bare soil simulation in which the Dead Sea is set to bare
soil are compared. NWP simulations focus on heavy precipitation events
exhibiting relevant differences between the Dead Sea and the bare soil
decadal realization to assess the impact on the underlying
convection-related processes. The change in the conditions of the Dead Sea is seen to affect the
atmospheric conditions leading to convection in two ways. (a) The local
decrease in evaporation reduces moisture availability in the lower boundary
layer locally and in the neighbouring regions, directly affecting atmospheric
stability. Weaker updraughts characterize the drier and more stable atmosphere
of the simulations in which the Dead Sea has been dried out. (b) Thermally
driven wind system circulations and resulting divergence/convergence fields
are altered, preventing in many occasions the initiation of convection because of the omission of convergence lines. On a decadal scale, the difference
between the simulations suggests a weak decrease in evaporation, higher air
temperatures and less precipitation (less than 0.5 %).

Abstract. Identification of various emission sources and quantification of their
contributions comprise an essential step in formulating scientifically sound
pollution control strategies. Most previous studies have been based on
traditional offline filter analysis of aerosol major components (usually
inorganic ions, elemental carbon – EC, organic carbon – OC, and elements).
In this study, source apportionment of PM2.5 using a positive matrix
factorization (PMF) model was conducted for urban Shanghai in the Yangtze
River Delta region, China, utilizing a large suite of molecular and
elemental tracers, together with water-soluble inorganic ions, OC, and EC
from measurements conducted at two sites from 9 November to 3 December 2018. The PMF analysis with inclusion of molecular makers (i.e., MM-PMF)
identified 11 pollution sources, including 3 secondary-source factors
(i.e., secondary sulfate; secondary nitrate; and secondary organic aerosol, SOA, factors) and 8 primary sources (i.e., vehicle exhaust, industrial
emission and tire wear, industrial emission II, residual oil combustion, dust,
coal combustion, biomass burning, and cooking). The secondary sources
contributed 62.5 % of the campaign-average PM2.5 mass, with the
secondary nitrate factor being the leading contributor. Cooking was a minor contributor (2.8 %) to PM2.5 mass while a significant
contributor (11.4 %) to the OC mass. Traditional PMF analysis relying on
major components alone (PMFt) was unable to resolve three
organics-dominated sources (i.e., biomass burning, cooking, and SOA source
factors). Utilizing organic tracers, the MM-PMF analysis determined that
these three sources combined accounted for 24.4 % of the total PM2.5
mass. In PMFt, this significant portion of PM mass was apportioned to
other sources and thereby was notably biasing the source apportionment outcome.
Backward trajectory and episodic analysis were performed on the MM-PMF-resolved source factors to examine the variations in source origins and
composition. It was shown that under all episodes, secondary nitrate and the
SOA factor were two major source contributors to the PM2.5 pollution.
Our work has demonstrated that comprehensive hourly data of molecular
markers and other source tracers, coupled with MM-PMF, enables examination
of detailed pollution source characteristics, especially organics-dominated
sources, at a timescale suitable for monitoring episodic evolution and with
finer source breakdown.

Abstract. Iodine chemistry has noteworthy impacts on the oxidising capacity of the
marine boundary layer (MBL) through the depletion of ozone (O3) and
changes to HOx (OH∕HO2) and NOx (NO∕NO2) ratios.
Hitherto, studies have shown that the reaction of atmospheric O3 with
surface seawater iodide (I−) contributes to the flux of iodine species
into the MBL mainly as hypoiodous acid (HOI) and molecular iodine (I2).
Here, we present the first concomitant observations of iodine oxide (IO),
O3 in the gas phase, and sea surface iodide concentrations. The results
from three field campaigns in the Indian Ocean and the Southern Ocean during
2015–2017 are used to compute reactive iodine fluxes in the MBL.
Observations of atmospheric IO by multi-axis differential
optical absorption spectroscopy (MAX-DOAS) show active iodine chemistry in
this environment, with IO values up to 1 pptv (parts per trillion by volume)
below latitudes of 40∘ S. In order to compute the sea-to-air
iodine flux supporting this chemistry, we compare previously established
global sea surface iodide parameterisations with new region-specific
parameterisations based on the new iodide observations. This study shows
that regional changes in salinity and sea surface temperature play a role in
surface seawater iodide estimation. Sea–air fluxes of HOI and I2,
calculated from the atmospheric ozone and seawater iodide concentrations
(observed and predicted), failed to adequately explain the detected IO in
this region. This discrepancy highlights the need to measure direct fluxes
of inorganic and organic iodine species in the marine environment. Amongst
other potential drivers of reactive iodine chemistry investigated,
chlorophyll a showed a significant correlation with atmospheric IO (R=0.7
above the 99 % significance level) to the north of the polar front. This
correlation might be indicative of a biogenic control on iodine sources in
this region.
Shape dependence of snow crystal fall speed
Authors: Vázquez-Martín Sandra , Kuhn Thomas , Eliasson Salomon
Published: October 2020

Abstract. Improved snowfall predictions require accurate knowledge of the properties of ice crystals and snow particles, such as their size, cross-sectional area, shape, and fall speed. In particular, the shape is an important parameter as it strongly influences the scattering properties of these ice particles, and thus their response to remote sensing techniques such as radar measurements. The fall speed of ice particles is a critical parameter for the representation of ice clouds and snow in atmospheric numerical models, as it determines the rate of removal of ice from the modelled clouds. They are also required for snowfall predictions alongside other properties such as ice particle size, cross-sectional area, and shape. For example, shape is important as it strongly influences the scattering properties of these ice particles, and thus their response to remote sensing techniques. This work analyses fall speed as a function of shape and other properties using ground-based in-situ measurements. The measurements for this study were done in Kiruna, Sweden during the snowfall seasons of 2014 to 2019, using the ground-based in-situ instrument Dual Ice Crystal Imager (D-ICI). The resulting data consist of high-resolution images of falling hydrometeors from two viewing geometries that are used to determine size (maximum dimension), cross-sectional area, area ratio, orientation, and the fall speed of individual particles. The selected dataset covers sizes from about 0.06 to 3.2 mm and fall speeds from 0.06 to 1.6 m s−1. The particles are shape-classified into 15 different shape groups depending on their shape and morphology. For these 15 shape groups relationships are studied, firstly, between size and cross-sectional area, then between fall speed and size or cross-sectional area. The data show in general low correlations to fitted fall-speed relationships due to large spread observed in fall speed. After binning the data according to size or cross-sectional area, correlations improve and we can report reliable parameterizations of fall speed vs. size or cross-sectional area for part of the shapes. The effects of orientation and area ratio on the fall speed are also studied, and measurements show that vertically orientated particles fall faster on average. However, most particles for which orientation can be defined fall horizontally.
Decoupling of urban CO2 and air pollutant emission reductions during the European
SARS-CoV2 lockdown
Authors: Lamprecht Christian , Graus Martin , Striednig Marcus , Stichaner Michael , Karl Thomas
Published: October 2020

Abstract. Lockdown and the associated massive reduction in people’s mobility imposed by SARS-CoV-2 mitigation measures across the globe provide a unique sensitivity experiment to investigate impacts on carbon and air pollution emissions. We present an integrated observational analysis based on long-term in-situ multispecies eddy flux measurements, allowing to quantify near real time changes of urban surface emissions for key air quality and climate tracers. During the first European SARS-CoV-2 wave we find that the emission reduction of classic air pollutants decoupled from CO2 and was significantly larger. These differences can only be rationalized by the different nature of urban combustion sources, and point towards a systematic bias of extrapolated urban NOx emissions in state-of the art emission models. The analysis suggests that European policies, shifting residential, public and commercial energy demand towards cleaner combustion, have helped to improve air quality more than expected, and that the urban NOx flux remains to be dominated (e.g. > 90 %) by traffic.
Eddies in motion: visualizing boundary-layer turbulence above an
open boreal peatland using UAS thermal videos
Authors: Alekseychik Pavel , Katul Gabriel , Korpela Ilkka , Launiainen Samuli
Published: October 2020

Abstract. High resolution thermal infrared (TIR) imaging is opening up new vistas in biosphere-atmosphere heat exchange studies. The rapidly developing unmanned aerial systems (UAS) and specially designed TIR cameras offer opportunities for TIR survey with increasingly high resolution, reduced noise, prolonged flight times and better gimbals. A state-of-the-art science platform is assembled using a Matrice 210 V2 drone equipped with a Zenmuse XT2 thermal camera and deployed over a pristine boreal peatland with the aim to test its performance in a heterogeneous ecosystem with short vegetation. The study utilizes the capability of the UAS platform to hover for prolonged times (about 20 min) whilst recording high-frequency (1–30 Hz) TIR videos. A methodology to derive thermal signatures of near-ground coherent turbulent structures impinging on the land surface, surface temperature spectra and heat fluxes from the retrieved videos is developed. The size, residence time and movement of the coherent structures are computed from the surface temperature maps, and their dependency on atmospheric conditions is examined. A ground-based eddy-covariance system and a collocated meteorological setup are used for reference.
Observation of Cirrus Clouds with GLORIA during the WISE
Campaign: Detection Methods and Cirrus Characterization
Authors: Bartolome Garcia Irene , Spang Reinhold , Ungermann Jörn , Griessbach Sabine , Krämer Martina , Höpfner Michael , Riese Martin
Published: October 2020

Abstract. Cirrus clouds contribute to the general radiation budget of the Earth, playing an important role in climate projections. Of special interest are optically thin cirrus clouds close to the tropopause due to the fact that their impact is not yet well understood. Measuring these clouds is challenging as both high spatial resolution as well as a very high detection sensitivity are needed. These criteria are fulfilled by the infrared limb sounder GLORIA (Gimballed Limb Observer for Radiance Imaging of the Atmosphere). This study presents a characterization of observed cirrus clouds using the data obtained by GLORIA aboard the German research aircraft HALO during the WISE (Wave-driven ISentropic Exchange) campaign in September/October 2017. We developed an optimized cloud detection method and derived macro-physical characteristics of the detected cirrus clouds such as cloud top height, cloud top bottom height, vertical extent and cloud top position with respect to the tropopause. The fraction of cirrus clouds detected above the tropopause is in the order of 13 % to 27 %. In general, good agreement with the clouds predicted by the ERA5 reanalysis data-set is obtained. However, cloud occurrence is ≈ 50 % higher in the observations for the region close to and above the tropopause. Cloud bottom heights are also detected above the tropopause. However, considering the uncertainties, we cannot confirm the formation of unattached cirrus layers above the tropopause.
Effects of Transient Processes for Thermal Simulations of the
Central European Basin
Authors: Degen Denise , Cacace Mauro
Published: October 2020

Abstract. Transient processes play a major role in geophysical applications. In this paper, we quantify the significant influence arising from transient processes for conductive heat transfer problems for sedimentary basin systems. We demonstrate how the thermal properties are affected by changing the system from a stationary to a non-stationary system and what impact transient boundary conditions (derived from paleoclimate information) have. Furthermore, we emphasize the importance of time-stepping approaches and the simulation duration since both factors influence the sensitivities of the thermal properties. We employ global sensitivity analyses to quantify not only the impact arising from the thermal properties but also their parameter correlations. Furthermore, we show how the results of the sensitivity analysis can be used to gain further insights into the complex Central European Basin System. This computationally very demanding workflow becomes feasible through the construction of high precision surrogate models using the reduced basis method.

Abstract. BCC-CSM2-HR is a high-resolution version of the Beijing Climate Center (BCC) Climate System Model. Its development is on the basis of the medium-resolution version BCC-CSM2-MR which is the baseline for BCC participation to the Coupled Model Intercomparison Project Phase 6 (CMIP6). This study documents the high-resolution model, highlights major improvements in the representation of atmospheric dynamic core and physical processes. BCC-CSM2-HR is evaluated for present-day climate simulations from 1971 to 2000, which are performed under CMIP6-prescribed historical forcing, in comparison with its previous medium-resolution version BCC-CSM2-MR. We focus on basic atmospheric mean states over the globe and variabilities in the tropics including the tropic cyclones (TCs), the El Niño–Southern Oscillation (ENSO), the Madden-Julian Oscillation (MJO), and the quasi-biennial oscillation (QBO) in the stratosphere. It is shown that BCC-CSM2-HR keeps well the global energy balance and can realistically reproduce main patterns of atmosphere temperature and wind, precipitation, land surface air temperature and sea surface temperature. It also improves in the spatial patterns of sea ice and associated seasonal variations in both hemispheres. The bias of double intertropical convergence zone (ITCZ), obvious in BCC-CSM2-MR, is almost disappeared in BCC-CSM2-HR. TC activity in the tropics is increased with resolution enhanced. The cycle of ENSO, the eastward propagative feature and convection intensity of MJO, the downward propagation of QBO in BCC-CSM2-HR are all in a better agreement with observation than their counterparts in BCC-CSM2-MR. We also note some weakness in BCC-CSM2-HR, such as the excessive cloudiness in the eastern basin of the tropical Pacific with cold Sea Surface Temperature (SST) biases and the insufficient number of tropical cyclones in the North Atlantic.
Efficient Bayesian inference for large chaotic dynamical
systems
Authors: Springer Sebastian , Haario Heikki , Susiluoto Jouni , Bibov Aleksandr , Davis Andrew , Marzouk Youssef
Published: October 2020

Abstract. Estimating parameters of chaotic geophysical models is challenging due to these models' inherent unpredictability. With temporally sparse long-range observations, these models cannot be calibrated using standard least squares or filtering methods. Obvious remedies, such as averaging over temporal and spatial data to characterize the mean behavior, do not capture the subtleties of the underlying dynamics. We perform Bayesian inference of parameters in high-dimensional and computationally demanding chaotic dynamical systems by combining two approaches: (i) measuring model-data mismatch by comparing chaotic attractors, and (ii) mitigating the computational cost of inference by using surrogate models. Specifically, we construct a likelihood function suited to chaotic models by evaluating a distribution over distances between points in the phase space; this distribution defines a summary statistic that depends on the attractor's geometry, rather than on pointwise matching of trajectories. This statistic is computationally expensive to simulate, compounding the usual challenges of Bayesian computation with physical models. Thus we develop an inexpensive surrogate for the log-likelihood via local approximation Markov chain Monte Carlo, which in our simulations reduces the time required for accurate inference by orders of magnitude. We investigate the behavior of the resulting algorithm on model problems, and then use a quasi-geostrophic model to demonstrate its large-scale application.
Observations of sea ice melt from Operation IceBridge imagery

Published: October 2020

Abstract. The summer albedo of Arctic sea ice is heavily dependent
on the fraction and color of melt ponds that form on the ice surface. This
work presents a new dataset of sea ice surface fractions along Operation
IceBridge (OIB) flight tracks derived from the Digital Mapping System
optical imagery set. This dataset was created by deploying version 2 of the
Open Source Sea-ice Processing (OSSP) algorithm to NASA's Advanced
Supercomputing Pleiades System. These new surface fraction results are then
analyzed to investigate the behavior of meltwater on first-year ice in
comparison to multiyear ice. Observations herein show that first-year ice
does not ubiquitously have a higher melt pond fraction than multiyear ice
under the same forcing conditions, contrary to established knowledge in the
sea ice community. We discover and document a larger possible spread of pond
fractions on first-year ice leading to both high and low pond coverage, in
contrast to the uniform melt evolution that has been previously observed on
multiyear ice floes. We also present a selection of optical images that
capture both the typical and atypical ice types, as observed from the OIB
dataset. The derived OIB data presented here will be key to explore the
behavior of melt pond formation Arctic sea ice.

Published: October 2020

Let R be a prime ring with extended centroid C, I a non-zero ideal of R and n ≥ 1 a fixed integer. If R admits the generalized derivations H and G such that (H(xy)+G(yx))n= (xy ±yx) for all x,y ∈ I, then one ofthe following holds:(1) R is commutative;(2) n = 1 and H(x) = x and G(x) = ±x for all x ∈ R.Moreover, we examine the case where R is a semiprime ring. Finally, we apply the above result to non-commutative Banach algebras.

Multiplicative-sum Zagreb index of splice, bridge, and bridge-cycle graphs
Authors: Azari Mahdieh
Published: October 2020

The multiplicative-sum Zagreb index is a graph invariant defined as the product of the sums of the degrees of pairs of adjacent vertices in a graph. In this paper, we compute the multiplicative-sum Zagreb index of some composite graphs such as splice graphs, bridge graphs, and bridge-cycle graphs in terms of the multiplicative-sum Zagreb indices of their components. Then, we apply our results to compute the multiplicative-sum Zagreb index for several classes of chemical graphs and nanostructures.

Introduction: Both human immunodeficiency virus (HIV) infection and acquired immunodeficiency syndrome (AIDS) are part of the National List of Compulsory Notification of Diseases. Despite the compulsory reporting of HIV infection from 2014, there has been a drop in the detection of new cases in the last five years. Objective: Analyze the epidemiological data of HIV/AIDS case reports in the city of Passo Fundo, Rio Grande do Sul, from 2007 to 2017 in relation to gender, neighborhoods, notifying units and treatment units. Methods: Retrospective descriptive study, accomplished at the Health Surveillance Sector from the compulsory notifications available in the Information System of Notifiable Diseases (Sistema de Informação de Agravos de Notificação – SINAN). A spreadsheet was made in the Microsoft Excel® Program (2016). Data were analyzed using the SPSS® Program, descriptively through measures of prevalence, incidence and distribution. Results: There were 1,068 notifications. There was a predominance of males (55.5%) and in the age group from 27 to 43 years. Of the 31 notifying health units, three concentrated 95% of the cases: Specialized Care Service (74.7%); Hospital São Vicente de Paulo (16%); and Hospital das Clínicas of Passo Fundo (4%). The same three units concentrated 98.0% of the treatments: 88, 9 and 1%, respectively. The primary care accounted for 5.0% of the notifications. Conclusion: The higher prevalence in young adult men denotes the importance of prevention aimed at this audience. Notifications were mostly from hospitals and a public referral center, with little involvement of primary care in reporting HIV/AIDS.

Introduction: Syphilis is an infectious disease caused by Treponema pallidum, its two main routes of transmission are sexual and transplacental (vertical). The latter is of particular worrisome, since it can generate congenital syphilis and can be avoided by early maternal serological screening. Objective: To analyze the conditions of prenatal care for syphilitic pregnant women in Sergipe State between 2007 and 2019. Methods: A cross-sectional, retrospective, and descriptive study was carried out, with the collection of notified cases of gestational and congenital syphilis in the Brazilian Notifiable Diseases Information System (Sistema de Informação de Agravos de Notificação - SINAN). Results: There was a considerable increase in the number of reported cases of gestational syphilis in the last 13 years. About 36% of pregnant women were identified in the 3rd trimester of pregnancy, 68.1% were brown, 56.8% had studied for up to 8 years, and 50.1% were between 20 and 29 years old. The clinical phase latent to the diagnosis was responsible for 70.3% of the cases, followed by the primary (11%) and tertiary (7.3%) phases. Of the total number of pregnant women, 20.2% did not perform the non-treponemal test, and 97.2% were treated with penicillin. Regarding the numbers of congenital syphilis, although 75% of the mothers performed prenatal care, 37.8% received the diagnosis at the time of delivery/curettage, resulting in 72.9% of infant deaths from the disease. Moreover, there was a predominance of untreated partners (77.7%) in relation to those treated (10.8%). Conclusion: Although most of them performed prenatal care, there was a predominance of diagnoses performed only in the 3rd trimester of pregnancy, mainly at the time of delivery or curettage, not respecting the minimum therapeutic interval of 30 days before delivery. Thus, in Sergipe State, the most important factor in the high prevalence of vertical transmission of syphilis is the ineffectiveness of prenatal care provided to infected pregnant women, which remains.
