Capitalism, Cameralism, and the Discovery of the Future, 1300s–2000s
Authors: Rössner Philipp Robinson 
Published: April 2021

Modern models of economic growth and capitalist modernity rest on capital accumulation, inclusive institutions, and various often unquantifiable aspects of “culture” (to which institutions belong). Scholars have also pinpointed the ability, or rather illusion, of human individuals to plan and predict their economic and social future(s). This transition to future thinking opened European’s spaces of possibility during what Reinhart Koselleck famously labelled Europe’s Sattelzeit, c.1750–1850. Some have emphasized a European culture of dealing with contingency, which may have marked out a specific “Western” path toward modernity.Without making a claim to global history, and focusing on the German speaking lands, I propose that the discovery of the open economic future was a much earlier project. Modern capitalism had roots in continental economic visions as early as the 1500s. We know them under common labels such as “Cameralism” and “mercantilism.” They were also apparent in Anglo-Saxon and Swedish economic reasoning since the mid-seventeenth century, suggesting that we may speak of a broader European tradition. The present article thus wishes to add to the debate, showing possibilities of an alternative—or a wider, more inclusive—genealogy of the modern economic mind, pointing out fresh ways of bringing together culture and economic development.

Authors: Wang F. , Slivken S. , Razeghi M. 
Published: April 2021

High-power, high-speed quantum cascade lasers (QCLs) with stable emission in the mid-infrared regime are of great importance for applications in metrology, telecommunication, and fundamental tests of physics. Owing to the intersubband transition, the unique ultrafast gain recovery time of the QCL with picosecond dynamics is expected to overcome the modulation limit of classical semiconductor lasers and bring a revolution for the next generation of ultrahigh-speed optical communication. Therefore, harmonic injection locking, offering the possibility to fast modulate and greatly stabilize the laser emission beyond the rate limited by cavity length, is inherently adapted to QCLs. In this work, we demonstrate for the first time the harmonic injection locking of a mid-infrared QCL with an output power over 1 W in continuous-wave operation at 288 K. Compared with an unlocked laser, the intermode spacing fluctuation of an injection-locked QCL can be considerably reduced by a factor above

, which permits the realization of an ultrastable mid-infrared semiconductor laser with high phase coherence and frequency purity. Despite temperature change, this fluctuation can be still stabilized to hertz level by a microwave modulation up to

. These results open up the prospect of the applications of mid-infrared QCL technology for frequency comb engineering, metrology, and the next-generation ultrahigh-speed telecommunication. It may also stimulate new schemes for exploring ultrafast mid-infrared pulse generation in QCLs.

Published: April 2021

Background
Coronavirus disease 2019 (COVID-19) is a systemic disease that can rapidly progress into acute respiratory failure and death. Timely identification of these patients is crucial for a proper administration of health-care resources.

Objective
To develop a predictive score that estimates the risk of invasive mechanical ventilation (IMV) among patients with COVID-19.

Study design
Retrospective cohort study of 401 COVID-19 patients diagnosed from March 12, to August 10, 2020. The score development cohort comprised 211 patients (52.62% of total sample) whereas the validation cohort included 190 patients (47.38% of total sample). We divided participants according to the need of invasive mechanical ventilation (IMV) and looked for potential predictive variables.

Results
We developed two predictive scores, one based on Interleukin-6 (IL-6) and the other one on the Neutrophil/Lymphocyte ratio (NLR), using the following variables: respiratory rate, SpO2/FiO2 ratio and lactic dehydrogenase (LDH). The area under the curve (AUC) in the development cohort was 0.877 (0.823–0.931) using the NLR based score and 0.891 (0.843–0.939) using the IL-6 based score. When compared with other similar scores developed for the prediction of adverse outcomes in COVID-19, the COVID-IRS scores proved to be superior in the prediction of IMV.

Conclusion
The COVID-IRS scores accurately predict the need for mechanical ventilation in COVID-19 patients using readily available variables taken upon admission. More studies testing the applicability of COVID-IRS in other centers and populations, as well as its performance as a triage tool for COVID-19 patients are needed.

Published: April 2021

Background
The aim of the study was to assess the safety and glycemic outcomes with the use of a Do-It-Yourself (DIY) Hybrid Closed-Loop (HCL) system based on the AndroidAPS application in type 1 diabetes (T1D).

Methods
Single-center clinical trial, with 3-week run-in and 12-week study period. DIY HCL system consisted of the Dana Diabecare RS insulin pump, Dexcom G5 continuous glucose monitoring system and AndroidAPS application. Primary outcome was safety: incidences of severe hypoglycemia, diabetic ketoacidosis, time spent in glycemia <54 mg/dl. Secondary endpoints included percentage of time in range (TIR) 70–180 mg/dl, time below 70 mg/dl, HbA1c, insulin requirements, and body weight.

Results
In total 12 subjects (5 men, 7 women) were enrolled, mean age 31.3±6.7, 95%CI(27.7–34.9) years, mean diabetes duration 16.1±5.7, 95%CI(13.0–19.2) years. No episodes of severe hypoglycemia or ketoacidosis were observed. Percentage of time spent in glycemia below 54mg/dl was not increased. Average sensor glycemia was lower in the study period than baseline (141.1 ± 8.4, 95%CI(136.3–145.9) vs. 153.3 ± 17.9, 95%CI(143.2–163.4), mg/dl p<0.001). TIR 70–180 mg/dl was improved by 11.3%, 95%CI(2.8%-19.8%) (from 68.0 ± 12.7 to 79.3 ± 6.4%, p<0.001), without increasing hypoglycemia time. The HbA1c level decreased by -0.5%, 95%CI(-0.9%–-0.1%) (from 6.8 ± 0.5 to 6.3 ± 0.4%, p<0.001). Additionally, in the last 4 weeks of the study period participants significantly improved and showed TIR 70–180 mg/dl 82.1 ± 5.6%, 95%CI(78.9–85.3), time <54 mg/dl 0.30 (0.20–0.55)%, median 95%CI(0.1–0.7) and <70 mg/dl 1.90 (1.10–3.05)%, median 95%CI(0.7–3.2). The insulin requirement and body weight did not change in the study.

Conclusions
The study revealed safety of the Do-It-Yourself HCL system AndroidAPS in adults with T1D, limited to well-controlled, highly selected and closely monitored patients. The use of AndroidAPS significantly improved HbA1c, time in range and average sensor glycemia without increasing hypoglycemia. As both patients and their medical team are gaining experience using the system over time, they improve glycemic control.

Authors: Faye Mbaye , Dème Abdoulaye , Diongue Abdou Kâ , Diouf Ibrahima 
Published: April 2021

ObjectiveThe aim of this study is to find the most suitable heat wave definition among 15 different ones and to evaluate its impact on total, age-, and gender-specific mortality for Bandafassi, Senegal.MethodsDaily weather station data were obtained from Kedougou situated at 17 km from Bandafassi from 1973 to 2012. Poisson generalized additive model (GAM) and distributed lag non-linear model (DLNM) are used to investigate the effect of heat wave on mortality and to evaluate the nonlinear association of heat wave definitions at different lag days, respectively.ResultsHeat wave definitions, based on three or more consecutive days with both daily minimum and maximum temperatures greater than the 90thpercentile, provided the best model fit. A statistically significant increase in the relative risk (RRs 1.4 (95% Confidence Interval (CI): 1.2–1.6), 1.7 (95% CI: 1.5–1.9), 1.21 (95% CI: 1.08–1.3), 1.2 (95% CI: 1.04–1.5), 1.5 (95% CI: 1.3–1.8), 1.4 (95% CI: 1.2–1.5), 1.5 (95% CI: 1.07–1.6), and 1.5 (95% CI: 1.3–1.8)) of total mortality was observed for eight definitions. By using the definition based on the 90thpercentile of minimum and maximum temperature with a 3-day duration, we also found that females and people aged ≥ 55 years old were at higher risks than males and other different age groups to heat wave related mortality.ConclusionThe impact of heat waves was associated with total-, age-, gender-mortality. These results are expected to be useful for decision makers who conceive of public health policies in Senegal and elsewhere. Climate parameters, including temperatures and humidity, could be used to forecast heat wave risks as an early warning system in the area where we conduct this research. More broadly, our findings should be highly beneficial to climate services, researchers, clinicians, end-users and decision-makers.

Published: April 2021

Trata-se de relato da experiência de capacitação de profissionais da APS para inserção do DIU de cobre. A intervenção foi um curso teórico prático e de atualização em inserção de DIU, ofertado a médicos, enfermeiros e ginecologistas da APS. Participaram do curso 27 profissionais, sendo 6 médicos e 21 enfermeiros. Foram inseridos 147 DIUs. A média de inserções em 7 meses (de maio a dezembro de 2019) foi de 21, superando a dos dois anos anteriores (6,1 em 2017 e 12,7 em 2018). A intervenção configura uma inovação à prática de oferta dos métodos contraceptivos no Sistema Único de Saúde (SUS) de Betim, uma vez que ampliou e continuará ampliando o acesso das mulheres ao DIU e vem para amenizar a dificuldade já conhecida dos serviços públicos em incorporar, de forma efetiva, a assistência anticoncepcional, através de métodos reversíveis e não hormonais.
Educação infantil indígena:
Authors: Andrioli Luciana Regina , Faustino Rosangela Célia 
Published: April 2021

Dados Censitários (INEP, 2017), indicam um expressivo aumento no número de matrículas na educação básica nas escolas localizadas em Terras Indígenas. Discutimos neste artigo a Educação Infantil Indígena, tema pouco abordado, e um direito recente no Brasil. Problematizamos as políticas e orientações para essa etapa da educação básica, a participação indígena e o papel das famílias na educação infantil em uma comunidade Kaingang no Paraná, evidenciando aspectos da infância e da educação indígena, a formação e os dados sobre os professores da educação infantil, o espaço, as práticas e materiais didáticos, buscando explicitar a inserção da criança indígena na escola com a presença de mães indígenas que acompanham o processo. Essas discussões resultam de uma pesquisa documental e empírica com aporte da Teoria Histórico-Cultural. Os resultados evidenciam que os povos indígenas, em sua resistência organizada, atuam em espaços institucionais locais e governamentais, visando à inclusão no sistema de ensino, porém com ações para ressignificá-lo.

Historiografias de um epicentro da pobreza
Authors: Moreira Nathalia Claro 
Published: April 2021

Resenha do livro “Histórias da Pobreza no Brasil” (Ed. FURG, 2019), volume 6 da Coleção Direito e Justiça Social, organizado pelos professores e pesquisadores Fabiano Quadros Rückert, Jonathan Fachini da Silva, José Carlos da Silva Cardozo e Tiago da Silva Cesar. A presente resenha busca revisar criticamente esta importante publicação historiográfica cuja proposta foi compor uma obra que contemplasse diferentes escalas de análise sobre a pobreza associadas as particularidades históricas e socioeconômicas desde o Norte ao Sul do Brasil. Os quatorze capítulos desenvolvidos ao longo de cerca de 400 páginas conduzem o leitor a fluxos e lentes de análise distintas, embora estejam todos entrelaçados no terreno da História Social. Na esteira da história das coletividades, os capítulos do livro analisado buscam revelar os aspectos intrínsecos a construção histórico-social da condição de miséria dentro de classes marginalizadas, isto é, trabalhadores pobres, escravizados, encarcerados, órfãos, mestiços, desabrigados. A obra desnaturaliza a percepção das desigualdades sociais a partir do momento em que esmiúça as particularidades dos grupos envolvidos pela pobreza. Para tanto, o exercício dos autores remonta um delicado trabalho de análise de fontes documentais variadas como processos judiciais, relatos de viajantes, jornais, petições, leis, estatísticas sanitárias, documentos eclesiásticos, relatórios da administração pública e obras literárias.
Global Perturbation of Nonlinear Eigenvalues
Authors: López-Gómez Julián , Sampedro Juan Carlos 
Published: April 2021

AbstractThis paper generalizes the classical theory of perturbation of eigenvalues up to cover the most general setting where the operator surface𝔏:[a,b]×[c,d]→Φ0⁢(U,V){\mathfrak{L}:[a,b]\times[c,d]\to\Phi_{0}(U,V)},(λ,μ)↦𝔏⁢(λ,μ){(\lambda,\mu)\mapsto\mathfrak{L}(\lambda,\mu)}, depends continuously on theperturbation parameter, μ, and holomorphically, as well as nonlinearly, on thespectral parameter, λ, whereΦ0⁢(U,V){\Phi_{0}(U,V)}stands for the set of Fredholm operators of index zero betweenUandV. The main result is a substantial extension of a classical finite-dimensional theorem of T. Kato (see [T. Kato, Perturbation Theory for Linear Operators, 2nd ed., Class. Math., Springer, Berlin, 1995, Chapter 2, Section 5]).
New active learning algorithms for near-infrared spectroscopy in agricultural applications
Authors: Krause Julius , Günder Maurice , Schulz Daniel , Gruna Robin 
Published: April 2021

AbstractThe selection of training data determines the quality of a chemometric calibration model. In order to cover the entire parameter space of known influencing parameters, an experimental design is usually created. Nevertheless, even with a carefully prepared Design of Experiment (DoE), redundant reference analyses are often performed during the analysis of agricultural products. Because the number of possible reference analyses is usually very limited, the presented active learning approaches are intended to provide a tool for better selection of training samples.
Discovery of novel potential KIT inhibitors for the treatment of gastrointestinal stromal tumor
Authors: Jiang Lili , Zhang Zhongmin , Wang Zhen , Liu Yong 
Published: April 2021

Abstract
Numerous inhibitors of tyrosine-protein kinase KIT, a receptor tyrosine kinase, have been explored as a viable therapy for the treatment of gastrointestinal stromal tumor (GIST). However, drug resistance due to acquired mutations in KIT makes these drugs almost useless. The present study was designed to screen the novel inhibitors against the activity of the KIT mutants through pharmacophore modeling and molecular docking. The best two pharmacophore models were established using the KIT mutants’ crystal complexes and were used to screen the new compounds with possible KIT inhibitory activity against both activation loop and ATP-binding mutants. As a result, two compounds were identified as potential candidates from the virtual screening, which satisfied the potential binding capabilities, molecular modeling characteristics, and predicted absorption, distribution, metabolism, excretion, toxicity (ADMET) properties. Further molecular docking simulations showed that two compounds made strong hydrogen bond interaction with different KIT mutant proteins. Our results indicated that pharmacophore models based on the receptor–ligand complex had excellent ability to screen KIT inhibitors, and two compounds may have the potential to develop further as the future KIT inhibitors for GIST treatment.
A Gradient Discretisation Method for Anisotropic Reaction–Diffusion Models with Applications to the Dynamics of Brain Tumors
Authors: Alnashri Yahya , Alzubaidi Hasan 
Published: April 2021

AbstractA gradient discretisation method (GDM) is an abstract setting that designs the unified convergence analysis of several numerical methods for partial differential equations and their corresponding models. In this paper, we study the GDM for anisotropic reaction–diffusion problems, based on a general reaction term, with Neumann boundary condition. With natural regularity assumptions on the exact solution, the framework enables us to provide proof of the existence of weak solutions for the problem, and to obtain a uniform-in-time convergence for the discrete solution and a strong convergence for its discrete gradient. It also allows us to apply non-conforming numerical schemes to the model on a generic grid (the non-conformingℙ⁢1{\mathbb{P}1}finite element scheme and the hybrid mixed mimetic (HMM) methods). Numerical experiments using the HMM method are performed to assess the accuracy of the proposed scheme and to study the growth of glioma tumors in heterogeneous brain environment. The dynamics of their highly diffusive nature is also measured using the fraction anisotropic measure. The validity of the HMM is examined further using four different mesh types. The results indicate that the dynamics of the brain tumor is still captured by the HMM scheme, even in the event of a highly heterogeneous anisotropic case performed on the mesh with extreme distortions.
Absolute parallelism for 2-nondegenerate CR structures via bigraded Tanaka prolongation
Authors: Porter Curtis , Zelenko Igor 
Published: April 2021

Abstract
This article is devoted to the local geometry of everywhere 2-nondegenerate CR manifolds M of hypersurface type.
An absolute parallelism for such structures was recently constructed independently by Isaev and Zaitsev, Medori and Spiro, and Pocchiola in the minimal possible dimension (

in certain cases by the first author. In the present paper, we develop a bigraded (i.e.,

ℤ

-graded) analog of Tanaka’s prolongation procedure to construct an absolute parallelism for these CR structures in arbitrary (odd) dimension with Levi kernel of arbitrary admissible dimension. We introduce the notion of a bigraded Tanaka symbol – a complex bigraded vector space – containing all essential information about the CR structure. Under the additional regularity assumption that the symbol is a Lie algebra, we define a bigraded analog of the Tanaka universal algebraic prolongation, endowed with an anti-linear involution, and prove that for any CR structure with a given regular symbol there exists a canonical absolute parallelism on a bundle whose dimension is that of the bigraded universal algebraic prolongation. Moreover, we show that for each regular symbol there is a unique (up to local equivalence) such CR structure whose algebra of infinitesimal symmetries has maximal possible dimension, and the latter algebra is isomorphic to the real part of the bigraded universal algebraic prolongation of the symbol. In the case of 1-dimensional Levi kernel we classify all regular symbols and calculate their bigraded universal algebraic prolongations.
In this case, the regular symbols can be subdivided into nilpotent, strongly non-nilpotent, and weakly non-nilpotent. The bigraded universal algebraic prolongation of strongly non-nilpotent regular symbols is isomorphic to the complex orthogonal algebra

Published: April 2021

Abstract
The red edge band is considered as one of the diagnosable characteristics of green plants, but the large-scale remote sensing retrieval of fractional vegetation coverage (FVC) based on the red edge band is still rare. To explore the application of the red edge band in the remote sensing estimation of FVC, this study proposed a new vegetation index (normalized difference red edge index, RENDVI) based on the two red edge bands of Chinese GaoFen-6 satellite (GF-6). The FVC estimated by using three vegetation indices (NDVI, RENDVI1, and RENDVI2) were evaluated based on the field survey FVC obtained in Minqin Basin of Gansu Province. The results showed that there was a good linear correlation between the FVC estimated by GF-6 WFV data and the FVC investigated in the field, and the most reasonable estimation of FVC was obtained based on RENDVI2 model (R
2 = 0.97611 and RMSE = 0.07075). Meanwhile, the impact of three confidence levels (1, 2, and 5%) on FVC was also analyzed in this study. FVC obtained from NDVI and RENDVI2 has the highest accuracy at 2% confidence, while FVC based on RENDVI1 achieved the best accuracy at 5% confidence. It could be concluded that it is feasible and reliable to estimate FVC based on red edge bands, and the GF-6 Wide Field View (WFV) data with high temporal and spatial resolution provide a new data source for remote sensing estimation of FVC.
