BACKGROUND: The determination of the pre-treatment’s survival predictive factors is very important as a basis for clinicians to educate and determine appropriate management for patients.

AIM: This study aimed to determine the pre-treatment risk factors that predict survival in Indonesian subjects with breast cancer.

METHODS: This was a cohort retrospective study conducted on breast cancer subjects visiting Sanglah General Hospital from 2016 to 2020. Data were collected from Indonesian Cancer Registry medical records such as age, tumor size, lymph nodes, metastasis, Karnofsky score, serum CA15-3 level, hormonal receptor status (ER/PR), HER2, Ki-67, LVI, tumor-infiltrating lymphocytes, cell type, histological grade, and survival status until December 2020. Data were tabulated and analyzed statistically using SPSS 25.0.

RESULTS: The median survival of breast cancer in this study was 47 months (SD 4.851). Majority of breast cancer subjects with mortality outcome were those who had Karnofsky score less than 70, tumor size ≥5 cm with infiltration, presence of contralateral lymph node, with metastasis, serum CA15-3 level >25 IU/mL, negative hormonal receptor, negative HER2 receptor, Ki67 higher than 14, negative lymphovascular invasion, negative tumor-infiltrating lymphocytes, and histological Grade 3. Age and pathological type were not significantly differed the breast cancer outcome.

CONCLUSION: There were significant effects of tumor size, KGB status, metastasis, serum CA15-3 levels, hormone receptor, HER2 receptor, Karnofsky score, lymphovascular invasion, tumor-infiltrating lymphocytes, and histological grade on breast cancer subjects’ survival.

This study aimed to test if differences in soil salinity, plant richness and diversity were significantly affected by habitat, site and distance from the seashore at three sandy and three rocky coastal sites in north-western Sardinia.

Each site has been divided into three belts placed at an equal distance of 50 m from the shoreline. We measured soil salinity using a probe and vascular plants richness and diversity using linear transects at all sites. Average soil salinity varied from 0.115 g/l to 0.180 g/l; it was higher in the rocky habitats than in the sandy ones. A total of 21 species were found per transect/site at the rocky sites and 30 species per transect/site at the sandy sites, with an average of Shannon and Weaver's Diversity Index of 1.8 per each belt at each site. These data confirm that, also in the Mediterranean islands, there are coastal gradients of soil salinity from the seashore to inland areas and that also vascular plant richness and diversity are influenced by the distance from the sea. Soil salinity was strongly affected by the type of habitat, being average at the rocky coasts and negligible at the sandy shores. The site effect was not significant for both soil salinity and plant richness and diversity.

Let $ \{S_n\} $ be the Apéry-like sequence given by $ S_n = \sum_{k = 0}^n\binom nk\binom{2k}k\binom{2n-2k}{n-k} $. We show that for any odd prime $ p $, $ \sum_{n = 1}^{p-1}\frac {nS_n}{8^n}{\equiv} (1-(-1)^{\frac{p-1}2})p^2\ (\text{ mod}\ {p^3}) $. Let $ \{Q_n\} $ be the Apéry-like sequence given by $ Q_n = \sum_{k = 0}^n\binom nk(-8)^{n-k}\sum_{r = 0}^k\binom kr^3 $. We establish many congruences concerning $ Q_n $. For an odd prime $ p $, we also deduce congruences for $ \sum_{k = 0}^{p-1}\binom{2k}k^3\frac 1{64^k}\ (\text{ mod}\ {p^3}) $, $ \sum_{k = 0}^{p-1}\binom{2k}k^3\frac 1{64^k(k+1)^2}\ (\text{ mod}\ {p^2}) $ and $ \sum_{k = 0}^{p-1}\binom{2k}k^3\frac 1{64^k(2k-1)}\ (\text{ mod}\ p) $, and pose lots of conjectures on congruences involving binomial coefficients and Apéry-like numbers.

Jaya algorithm is a highly effective recent metaheuristic technique. This article presents a simple, precise, and faster method to estimate stress strength reliability for a two-parameter, Weibull distribution with common scale parameters but different shape parameters. The three most widely used estimation methods, namely the maximum likelihood estimation, least squares, and weighted least squares have been used, and their comparative analysis in estimating reliability has been presented. The simulation studies are carried out with different parameters and sample sizes to validate the proposed methodology. The technique is also applied to real-life data to demonstrate its implementation. The results show that the proposed methodology's reliability estimates are close to the actual values and proceeds closer as the sample size increases for all estimation methods. Jaya algorithm with maximum likelihood estimation outperforms the other methods regarding the bias and mean squared error.

Published: November 2021

Due to the problem of drinking water scarcity in different cities around the world, there are innovative proposals to automate garden irrigation in homes, to reduce drinking water consumption. For this research, a sample of 68 inhabitants of the Region of Arequipa - Peru has been surveyed to know the common habits in the irrigation of the gardens. From this data, two systems have been implemented in two average gardens using the Arduino UNO board (integrating with the Ethernet Shield) and the NodeMCU, each proposal integrates soil moisture sensors, water flow sensor, and actuators, such as the solenoid valve and the relay, besides centralizing the information through an IoT System (Home Assistant or Adafruit IO). This has managed to establish a comparison of both, generating a discussion according to the advantages and disadvantages addressed by each proposal and obtaining a saving of potable water in the irrigation of plants.

Published: November 2021

Augmented reality (AR) is an emerging technology that has permeated different spheres of life, one of them is education, and specifically the teaching-learning process at different educational levels and objects of study. For this reason, this paper presents the development of a learning model of quadric surfaces mediated by a mobile AR application and based on didactic engineering. The model was applied to a group of environmental engineering students of the Catholic University of Manizales. To obtain information on the use of the application and the learning results obtained, some intervention instruments were developed. The students stated that the use of AR allowed them to better understand the concepts of quadric surfaces, even more so in a time of pandemic by COVID-19, where education was highly measured by ICTs.

Des sociologues du travail utilisant la caméra comme outil central d’investigation, le suivi filmé durant 25 ans des transformations du travail dans une même entreprise, la production à partir de cette base d’observation d’une dizaine de films de recherche et de 250 heures de rushes… Telle est l’histoire que tente de retracer cet article : celle de la constitution d’un corpus filmé de recherche et des aléas divers de sa conservation. Soit, durant 30 ans, une sorte de parcours du combattant à tous les niveaux pour utiliser l’image, la produire, la légitimer en tant que recherche, et la préserver pour mieux la conserver. Un aperçu du hors champ et du volet caché de la recherche filmée sur l’histoire de « la Saga des Papeteries Canson et Montgolfier », qui nous a servi, entre autres, de trame d’analyse et de réflexion pour nos travaux sur les mutations du monde du travail et de l’entreprise depuis la fin des Trente Glorieuses jusqu’en ce début de xxie siècle. Rescapées de tous ces combats, ces images ont été, fin 2018, numérisées et sauvegardées par l’Ina.

Authors: Villalón Walter Roblero
Published: November 2021

El presente artículo tiene por finalidad relevar la importancia del rescate de las narraciones testimoniales sobre el periodo dictatorial en Chile en las zonas más alejadas e invisibilizadas del país. El Museo de la Memoria y los Derechos Humanos (MMDH), al constituirse como una institución de carácter nacional, tiene como misión dicha tarea, para lo cual ha desarrollado diferentes proyectos para el registro, conservación, descripción y puesta en valor de dichos relatos. Se trabaja en espacios donde se conjugan el temor con la impunidad; lugares remotos y pequeños, donde víctimas y victimarios conviven de manera cotidiana. El proceso social, cultural y político iniciado a partir de octubre de 2019, ha reavivado estos sentires y pensares respecto de la represión lo que propone un gran desafío en la resignificación de este pasado, que ha mostrado una continuidad en el presente.
Resilience to COVID-19 Through Lean Construction
Authors: Parameswaran Agana , Ranadewa K. A. T. O.
Published: November 2021

COVID-19 pandemic has been an alarming issue from the beginning of 2020 and is a significant disaster that affects each industry. In dealing with the consequences of the pandemic, the construction industry confronts several interruptions for the sustainable delivery of the projects. Many researchers stated that lean construction can minimise this impact. Lean thinking is about engaging everyone, every day in handling interruptions and learning to react better. However, few discussions are there pertaining to how to implement and why to implement lean. Therefore, this paper aims to investigate the impact of COVID-19 on the construction industry and evaluate the ability of lean construction to resilient COVID-19. Therefore, a comprehensive literature review has been carried out. The findings revealed 67 negative factors categorised under resources-related issues, project management issues, quality issues, financial issues, contractual issues, safety issues, technology-related issues, and other issues for the construction industry due to the pandemic. Continuous improvement for the work under any risks, improvement in project performance, more satisfaction, and better value for the employer were highlighted as the main benefits of lean construction during the new normalcy. The developed conceptual framework unlocked several research arenas on lean in post-COVID implementation for the construction industry.
Zebrafish sirt7 Negatively Regulates Antiviral Responses by Attenuating Phosphorylation of irf3 and irf7 Independent of Its Enzymatic Activity
Authors: Liao Qian , Ouyang Gang , Zhu Junji , Cai Xiaolian , Yu Guangqing , Zhou Ziwen , Liu Xing , Wang Jing , Xiao Wuhan
Published: November 2021

Sirt7 is one member of the sirtuin family proteins with NAD (NAD+)-dependent histone deacetylase activity. In this study, we report that zebrafish sirt7 is induced upon viral infection, and overexpression of sirt7 suppresses cellular antiviral responses. Disruption of sirt7 in zebrafish increases the survival rate upon spring viremia of carp virus infection. Further assays indicate that sirt7 interacts with irf3 and irf7 and attenuates phosphorylation of irf3 and irf7 by preventing tbk1 binding to irf3 and irf7. In addition, the enzymatic activity of sirt7 is not required for sirt7 to repress IFN-1 activation. To our knowledge, this study provides novel insights into sirt7 function and sheds new light on the regulation of irf3 and irf7 by attenuating phosphorylation.
PDGFRβ Recognizes and Binds Bacteria to Activate Src/Stat Pathway in Oysters

Published: November 2021

The Stat signaling pathway plays important roles in mediating the secretions of a large number of cytokines and growth factors in vertebrates, which is generally triggered by the growth factor receptor, cytokine receptor, G protein coupled receptor, and receptor protein tyrosine kinase. In the current study, a platelet-derived growth factor receptor (defined as CgPDGFRβ) was identified from the Pacific oyster Crassostrea gigas, with a signal peptide, three Ig domains, a transmembrane domain, and an intracellular Ser/Thr/Tyr kinase domain. The two N-terminal Ig domains of CgPDGFRβ showed relatively higher binding activity to Gram-negative bacteria and LPS compared with Gram-positive bacteria and peptidoglycan. Upon binding bacteria, CgPDGFRβ in hemocytes formed a dimer and interacted with protein tyrosine kinase CgSrc to induce the phosphorylation of CgSrc at Tyr416. The activated CgSrc interacted with CgStat to induce the translocation of CgStat into the nucleus of hemocytes, which then promoted the expressions of Big defensin 1 (CgBigdef1), IL17-4 (CgIL17-4), and TNF (CgTNF1). These findings together demonstrated that the Src/Stat signaling was activated after the binding of CgPDGFRβ with bacteria to induce the expressions of CgBigdef1, CgIL17-4, and CgTNF1.

Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 has become a pandemic disease. It also increases the risk of co-infections. Mucormycosis is a severe fungal infectious disease and its causative agent, mucormycetes, belongs to an opportunist fungus Mucoraceae family. Mucormycosis in COVID-19 patients with mucormycosis presents an additional challenge worldwide. Mucormycosis shares certain risk factors and signs and symptoms with COVID-19. In this review, we summarize manifestations and risk factors of mucormycosis and COVID-19.
Use of intraoperative mild hyperventilation to decrease the incidence of postoperative shoulder pain after laparoscopic gastric sleeve surgery: A prospective randomised controlled study
Authors: Bataineh Adel M. , Qudaisat Ibraheem Y , Banihani Mohammed , Obeidat Rawan , Hamasha Heba S
Published: November 2021

Background and Aims:

Post-laparoscopic shoulder pain (PLSP) is a common problem. It is a referred type of pain resulting from irritation of phrenic nerve endings. Multiple manoeuvres were used to decrease its incidence with varying success rates. In this study, we tested the use of mild intraoperative hyperventilation to reduce PLSP in patients undergoing laparoscopic sleeve gastrectomy surgery (LSG).

Methods:

Consenting American Society of Anesthesiologists-I and II patients undergoing LSG under general anaesthesia were randomly assigned to two groups. Group A (53 patients) received intraoperative mild hyperventilation with target end-tidal carbon dioxide (ETCO2) of 30–32 mmHg. Group B (51 patients) received conventional ventilation (ETCO2of 35–40 mmHg). Incidence and severity of PLSP, cumulative analgesic requirements and incidence of nausea and vomiting were recorded at 12 and 24 hours postoperatively and then followed up after discharge over the phone at 48 hours, 1 week, 1 month and 3 months. Statistical significance of differences between the two groups was defined atP< 0.05.

Results:

Incidence of PLSP was comparable between the two groups in the first 24 hours. The intervention group had a significantly lower incidence of PLSP throughout the remaining assessment points (56.6% vs. 80.4%, 30.2% vs. 78.4%, 15.1% vs. 70.6%, 3.8% vs. 35.3% at 36 hours, 48 hours, 1 week and 1 month, respectively,P< 0.05). The average PLSP pain score was significantly lower in the mild hyperventilation group at all assessment time points. Nausea and vomiting were non-significantly lower in the mild hyperventilation group.

Conclusion:

Mild intraoperative hyperventilation could be beneficial in reducing the incidence and severity of PLSP after LSG surgery.
Epidemiological characteristics of traumatic musculoskeletal injuries during the COVID-19 pandemic at a single tertiary hospital
Authors: Juhani Wazzan S. Al , Alanazi Abdullah M. , Aldusari Rakan S.
Published: November 2021

Background:

Musculoskeletal (MSK) injuries are common but can lead to devastating outcomes. During the COVID-19 pandemic in Saudi Arabia, it is thought that the burden of traumatic MSK injuries is minimized.

Objective:

This study aimed to assess the epidemiological characteristics of traumatic MSK injuries during the lockdown period in Saudi Arabia.

Materials and Methods:

This retrospective descriptive study included all patients who were admitted to the orthopedic department at a single tertiary hospital level 1 trauma center due to traumatic injuries from March 23 to June 21, 2020.

Results:

The study included 92 patients. The majority were male (68.5%). The most common comorbidity was hypertension (30.4%). Falls were the most common mechanism of injury (47%). The most common sites to be fractured were the proximal femur (22.8%) followed by the distal tibia/fibula (14%). Skull fractures (12%), rib fractures (6.5%), and pneumothorax (6.5%) were the most common associated injuries. Age and the number of injuries were significant predictors of increased length of hospital stay.

Conclusions:

Major considerations for primary prevention must be taken into account during long periods of time with no direct patient interaction. Patient education is important to help avoid any burden that might be caused by otherwise preventable injuries. Further studies should be conducted to assess this phenomenon more in depth and to establish the appropriate method of educating patients on primary prevention.

Published: November 2021

The lattice-based CRYSTALS-Dilithium scheme is one of the three thirdround digital signature finalists in the National Institute of Standards and Technology Post-Quantum Cryptography Standardization Process. Due to the complex calculations and highly individualized functions in Dilithium, its hardware implementations face the problems of large area requirements and low efficiency. This paper proposes several optimization methods to achieve a compact and high-performance hardware architecture for round 3 Dilithium. Specifically, a segmented pipelined processing method is proposed to reduce both the storage requirements and the processing time. Moreover, several optimized modules are designed to improve the efficiency of the proposed architecture, including a pipelined number theoretic transform module, a SampleInBall module, a Decompose module, and three modular reduction modules. Compared with state-of-the-art designs for Dilithium on similar platforms, our implementation requires 1.4×/1.4×/3.0×/4.5× fewer LUTs/FFs/BRAMs/DSPs, respectively, and 4.4×/1.7×/1.4× less time for key generation, signature generation, and signature verification, respectively, for NIST security level 5.

Published: November 2021

Forest is the most significant habitat for birds by supporting around 75% of all bird species while only 45% of all bird species have adapted to humans modified habitats. The research was conducted in the Montane Forest Research Station, Jos, Plateau State, in other to determine the abundance, diversity and effect of habitat types on bird’s species diversity. Fifteen transects of 200m were laid in the three habitat types (riparian forest, farmland and residential area) using stratified random sampling method. The data collected were analysed using R console. Shannon Weiner diversity index was used to analyse species diversity while generalized linear model was used to determine the effect of the habitat variables on bird species diversity. The result showed a total number of 1466 individual birds belonging to 17 families and 60 bird species were sighted. The abundance of birds was highest in riparian forest (2252), farmland (1732) and Residential area (1094) with no significance difference (p=0.177). Species richness was higher in the riparian forest (57), farmland (49), and the residential area (44). It also revealed that bird diversity index was highly significant. Riparian forest had the highest diversity (4.77), and the species were more evenly distributed (0.6) as compared to the other habitat types. The higher the number of trees and canopy cover the higher the diversity of species as was observed in the riparian forest where forest species that weren’t seen in the other habitats were found. The farmland and residential areas also hold a considerable number of some generalist bird species due to some patches of vegetation found in the habitat. Therefore, conservation efforts should be directed towards keeping vegetation intact in human dominated areas, as it serves as repository for bird species which are ecologically important. Hence, planting trees (economic, fruit and ornamental) should be encouraged.

Authors: Cianconi Regina de Barros , Almeida Camilla Castro de
Published: November 2021

Objetivo: A perspectiva de desenvolvimento de cidades inteligentes (smart cities) é uma tendência para a Administração Pública brasileira. Trata-se de um modelo de gestão tecnológico, interconectado e eficiente que supre a urgência de indicadores e estratégias para um planejamento inovador e sustentável. O conceito parte da utilização de tecnologias de informação e comunicação (TIC), mas evolui progressivamente até uma visão holística do sistema urbano, considerando suas dimensões: tecnologia (infraestrutura), pessoas (educação) e instituições (governança). Este artigo tem como objetivo analisar o potencial de atuação das bibliotecas públicas para o desenvolvimento de cidades inteligentes a fim de contribuir para uma visão mais ampla, necessária e humana do modelo de cidades inteligentes.
Método: A pesquisa caracteriza-se como bibliográfica e documental, de caráter exploratório. Para atingir o objetivo do artigo foi realizada uma revisão de literatura com posterior análise de conteúdo como técnica de tratamento dos dados qualitativos obtidos, o que permitiu inferir as contribuições das bibliotecas públicas no contexto em estudo.
Resultado: A recuperação de apenas um trabalho brasileiro que discute a relação entre bibliotecas e cidades inteligentes demonstra essa lacuna na literatura nacional de Biblioteconomia e Ciência da Informação. A partir da análise de conteúdo realizada nos 53 trabalhos recuperados, foram identificadas as seguintes contribuições das bibliotecas públicas para o desenvolvimento de cidades inteligentes: disponibilização de internet, promoção de competência informacional e midiática, fomento e incentivo à inovação, acesso e disseminação de informação utilitária.
Conclusões: Conclui-se que, no contexto das cidades inteligentes, a biblioteca pública tem potencial para ser um equipamento público que viabiliza a participação cidadã e o desenvolvimento comunitário.

Authors: Nogueira Arlene Araujo , Bissoli Michelle de Freitas
Published: November 2021

O texto discute resultados de pesquisa de doutorado sobre interações e o desenvolvimento da fala em crianças na creche, cujo objetivo central foi o de compreender o processo de desenvolvimento da linguagem oral na etapa da primeira infância, de acordo com os pressupostos da Teoria Histórico-Cultural. Enfocamos no trabalho a linguagem e a comunicação que se formam entre um e dois anos, período que corresponde à idade das crianças pesquisadas. No percurso metodológico, adotamos concepções da pesquisa participante, construindo os dados em conjunto com os sujeitos, por intermédio de observações participativas do cotidiano, com o auxílio de registros fotográficos, audiovisuais e escritos, além de encontros formativos com as professoras. Os dados empíricos – interações vivenciadas entre as crianças e suas professoras, que favoreceram a emergência da linguagem oral – foram agrupados em duas categorias: 1) Interações comunicativas diretas: atividade comunicativa baseada na comunicação emocional; e 2) Interações comunicativas mediadas por objetos: atividade comunicativa apoiada na manipulação de objetos. A análise dos dados evidenciou que as atividades de interação das crianças com os adultos e destas entre si, na creche, favorecem a comunicação e o desenvolvimento de sua linguagem oral. Além disso, os momentos formativos com as professoras possibilitaram a reflexão sobre a sua própria prática, revelando o potencial formativo da pesquisa participante.

Published: November 2021

Este trabalho está inserido na área de Educação e Educação Matemática, cujo foco temático é o tratamento dado ao ensino de Geometria em pesquisas acadêmicas publicadas na região Nordeste. Nosso objetivo foi identificar os elementos estruturantes adotados nas teses e dissertações produzidas em programas de Pós-Graduação em Educação e Educação Matemática da região Nordeste, que abordam o ensino de Geometria no período 2010 a 2019. Para isso, utilizamos o aporte metodológico do estado da arte, no qual limitamos nossas buscas por dissertações e teses disponíveis no site da Biblioteca Digital Brasileira de Teses e Dissertações (BDTD) e no Catálogo de Teses e Dissertações da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES). Concluímos que o ensino de Geometria se apresenta como uma das áreas da Matemática pouco discutida nas pesquisas acadêmicas da região Nordeste. A ênfase no tratamento com a Geometria Plana indica que a perspectiva espacial e grandezas e medidas, contemplada em toda a escolarização, está sendo deixada de lado na formação dos estudantes, assim como a Geometria Analítica. Além disso, o Ensino Médio tem sido pouco discutido nas pesquisas o que sinaliza possibilidade de ruptura do ciclo de aprofundamento das habilidades a serem desenvolvidas durante a Educação Básica. Neste sentido, a carência de trabalho com a Geometria prejudica, em nossa população, o desenvolvimento de competências e habilidades intelectuais, a criatividade e a percepção espacial do mundo em que vivemos, características que são destacadas como passíveis de serem trabalhadas a partir dessa ciência.

Authors: Ismailov Abubakar , Muslimov Arsen
Published: November 2021

Consideration is given to the results of the study of etching processes ( 200 nm/min) of a ZnO film by a focused electron beam with medium energy (70 keV) under vacuum conditions of

910-5 Pa. It was shown that the construction of a model of the ZnO film etching during electron bombardment, taking into account the likely thermal desorption and electron-stimulated desorption, is not confirmed by calculations. A possible etching mechanism based on the radiolysis caused by Auger decay in near-surface layers of ZnO films is proposed.

Impact of modified turbulent diffusion of PM2.5 aerosol in WRF-Chem simulations in eastern China
Authors: Jia Wenxing , Zhang Xiaoye
Published: November 2021

Abstract. Correct description of the boundary layer mixing process
of particle is an important prerequisite for understanding the formation
mechanism of pollutants, especially during heavy pollution episodes.
Turbulent vertical mixing determines the distribution of momentum, heat,
water vapor and pollutants within the planetary boundary layer (PBL).
However, what is questionable is that the turbulent mixing process of particles
is usually denoted by turbulent diffusion of heat in the
Weather Research and Forecasting model coupled with Chemistry (WRF-Chem).
With mixing-length theory, the turbulent diffusion relationship of particle
is established, embedded into the WRF-Chem and verified based on long-term
simulations from 2013 to 2017. The new turbulent diffusion coefficient is
used to represent the turbulent mixing process of pollutants separately,
without deteriorating the simulation results of meteorological parameters.
The new turbulent diffusion improves the simulation of pollutant
concentration to varying degrees, and the simulated results of PM2.5
concentration are improved by 8.3 % (2013), 17 % (2014), 11 % (2015)
and 11.7 % (2017) in eastern China, respectively. Furthermore, the
pollutant concentration is expected to increase due to the reduction of
turbulent diffusion in mountainous areas, but the pollutant concentration
did not change as expected. Therefore, under the influence of complex
topography, the turbulent diffusion process is insensitive to the simulation
of the pollutant concentration. For mountainous areas, the evolution of
pollutants is more susceptible to advection transport because of the
simulation of obvious wind speed gradient and pollutant concentration
gradient. In addition to the PM2.5 concentration, the concentration of
CO as a primary pollutant has also been improved, which shows that the
turbulent diffusion process is extremely critical for variation of the
various aerosol pollutants. Additional joint research on other processes
(e.g., dry deposition, chemical and emission processes) may be necessary to
promote the development of the model in the future.
Importance of the Webb, Pearman, and Leuning (WPL) correction for the measurement of small CO2 fluxes
Authors: Jentzsch Katharina , Boike Julia , Foken Thomas
Published: November 2021

Abstract. The WPL (Webb,
Pearman, and Leuning) correction is fully accepted to
correct trace gas fluxes like CO2 for density fluctuations due to water
vapour and temperature fluctuations for open-path gas analysers. It is known
that this additive correction can be on the order of magnitude of the actual
flux. However, this is hardly ever included in the analysis of data quality.
An example from the Arctic shows the problems, because the size of the
correction is a multiple of the actual flux. As a general result, we
examined and tabulated the magnitude of the WPL correction for carbon
dioxide flux as a function of sensible and latent heat flux. Furthermore, we
propose a parameter to better estimate possible deficits in data quality and
recommend integrating the quality flag derived with this parameter into the
general study of small carbon dioxide fluxes.
A 1 km global cropland dataset from 10 000 BCE to 2100 CE

Published: November 2021

Abstract. Cropland greatly impacts food security, energy supply,
biodiversity, biogeochemical cycling, and climate change. Accurately and
systematically understanding the effects of agricultural activities requires
cropland spatial information with high resolution and a long time span. In
this study, the first 1 km resolution global cropland proportion dataset for
10 000 BCE–2100 CE was produced. With the cropland map initialized in 2010 CE, we first harmonized the cropland demands extracted from the History
Database of the Global Environment 3.2 (HYDE 3.2) and the Land-Use
Harmonization 2 (LUH2) datasets and then spatially allocated the demands
based on the combination of cropland suitability, kernel density, and other
constraints. According to our maps, cropland originated from several
independent centers and gradually spread to other regions, influenced by
some important historical events. The spatial patterns of future cropland
change differ in various scenarios due to the different socioeconomic
pathways and mitigation levels. The global cropland area generally shows an
increasing trend over the past years, from 0×106 km2 in 10 000 BCE
to 2.8×106 km2 in 1500 CE, 6.2×106 km2 in 1850 CE,
and 16.4×106 km2 in 2010 CE. It then follows diverse trajectories
under future scenarios, with the growth rate ranging from 16.4 % to
82.4 % between 2010 CE and 2100 CE. There are large area disparities among
different geographical regions. The mapping result coincides well with
widely used datasets at present in both distribution pattern and total
amount. With improved spatial resolution, our maps can better capture the
cropland distribution details and spatial heterogeneity. The
spatiotemporally continuous and conceptually consistent global cropland
dataset serves as a more comprehensive alternative for long-term earth
system simulations and other precise analyses. The flexible and efficient
harmonization and downscaling framework can be applied to specific regions
or extended to other land use and cover types through the adjustable parameters
and open model structure. The 1 km global cropland maps are available at

Abstract. The first satellite-based global retrievals of terrestrial sun-induced
chlorophyll fluorescence (SIF) were achieved in 2011. Since then, a number of
global SIF datasets with different spectral, spatial, and temporal sampling characteristics have become available to the scientific community. These
datasets have been useful to monitor the dynamics and productivity of a range
of vegetated areas worldwide, but the coarse spatiotemporal sampling and low
signal-to-noise ratio of the data hamper their application over small or
fragmented ecosystems. The recent advent of the Copernicus Sentinel-5P TROPOMI
mission and the high quality of its data products promise to alleviate this
situation, as TROPOMI provides daily global measurements at a much denser
spatial and temporal sampling than earlier satellite instruments. In this
work, we present a global SIF dataset produced from TROPOMI measurements
within the TROPOSIF project funded by the European Space Agency. The current
version of the TROPOSIF dataset covers the time period between May 2018 and
April 2021. Baseline SIF retrievals are derived from the 743–758 nm
window. A secondary SIF dataset derived from an extended fitting window
(735–758 nm window) is included. This provides an enhanced signal-to-noise
ratio at the expense of a higher sensitivity to atmospheric effects. Spectral
reflectance spectra at seven 3 nm windows devoid of atmospheric absorption
within the 665–785 nm range are also included in the TROPOSIF dataset as an
important ancillary variable to be used in combination with SIF. The
methodology to derive SIF and ancillary data as well as results from an
initial data quality assessment are presented in this work. The TROPOSIF
dataset is available through the following digital object identifier (DOI):

SuperflexPy 1.3.0: an open-source Python framework for building, testing, and improving conceptual hydrological models
Authors: Dal Molin Marco , Kavetski Dmitri , Fenicia Fabrizio
Published: November 2021

Abstract. Catchment-scale hydrological models are widely used to represent and improve
our understanding of hydrological processes and to support operational water
resource management. Conceptual models, which approximate catchment
dynamics using relatively simple storage and routing elements, offer an
attractive compromise in terms of predictive accuracy, computational
demands, and amenability to interpretation. This paper introduces
SuperflexPy, an open-source Python framework implementing the SUPERFLEX
principles (Fenicia et al., 2011) for building conceptual
hydrological models from generic components, with a high degree of control
over all aspects of model specification. SuperflexPy can be used to build
models of a wide range of spatial complexity, ranging from simple lumped
models (e.g., a reservoir) to spatially distributed configurations (e.g., nested sub-catchments), with the ability to customize all individual model
components. SuperflexPy is a Python package, enabling modelers to exploit
the full potential of the framework without the need for separate software
installations and making it easier to use and interface with existing
Python code for model deployment. This paper presents the general
architecture of SuperflexPy, discusses the software design and
implementation choices, and illustrates its usage to build conceptual models
of varying degrees of complexity. The illustration includes the usage of
existing SuperflexPy model elements, as well as their extension to implement
new functionality. Comprehensive documentation is available online and
provided as a Supplement to this paper. SuperflexPy is available
as open-source code and can be used by the hydrological community to
investigate improved process representations for model comparison and for
operational work.
