Published: November 2020

<p class="p1">Water quality is a subject of intense scientific inquiry because of its repercussion in human’s life, agriculture or even energy generation. Remote sensing can be used to control water masses by analyzing biophysical variables. Chlorophyll-a (Chl-a) and Total Suspended Solids (SS) are a well-known feature of water quality. These variables have been measured in Sitjar reservoir (Castelló, Spain) as a part of the project Ecological Status of Aquatic Systems with Sentinel Satellites (ESAQS), in order to compare the results with satellite reflectance data. Two processes were compared to correct atmospherically the level 1C Sentinel 2 (S2) images. The results show that Case 2 Regional Coast Colour (C2RCC) method, with a Root Mean Square Error of 2.4 mg/m<span class="s1">3 </span>(Chl-a) and 3.9 g/m<span class="s1">3 </span>(SS) is a better tool for atmospheric correction in this scenario due to the low turbidity levels of water. Besides, in this paper we study the Chl-a and SS variability through April 2017 to March 2019 with fourteen S2 images with the automatic products from C2RCC correction, finding correlations between them and the climate and reservoir conditions. Chl-a increase from 0.4 mg/m<span class="s1">3 </span>to 9.5 mg/m<span class="s1">3 </span>while SS rise 18 g/m<span class="s1">3 </span>in this period, which makes Sitjar as an oligotrophic-mesotrophic system. The correlation results demonstrate an excellent correspondence between them (R<span class="s1">2</span>=0.9). Sitjar reservoir lost almost 40 hm<span class="s1">3 </span>at the beginning of the study, which it had a possible relationship with the increasing parameter values. Also discussed was the role played by the climatology in the reservoir conditions due to the changes in the water structure with seasons, which explains the ariability through the year.</p><p class="p1"> </p>

Published: November 2020

Abstract. The physical properties and radiative role of ice clouds
remain one of the uncertainties in the Earth–atmosphere system. In this
study, we present a detailed analysis of ice cloud properties based on 4 years of surface millimeter-wavelength radar measurements in Beijing, China,
where the summer monsoon from the ocean and the winter monsoon from the continent
prevail alternately, resulting in various ice clouds. More than 6300 ice
cloud clusters were studied to quantify the properties of ice clouds, such
as the height, optical depth and horizontal extent, which can serve as a
reference for parameterization and characterization in global climate
models. In addition, comparison between ice cloud clusters formed under the
summer monsoon and the winter monsoon indicates the different formation and
evolution mechanisms of cirrus clouds. Statistically, temperatures of more than
95 % of ice radar bins are below −15 ∘C and more than 80 %
of ice clouds are above 7 km. The dependence of the radar reflectivity of
ice particles on height and temperature was also observed in this study,
indicating that the reflectivity of ice bins increases (decreases) as the
temperature (height) increases. In addition, it is found that there is a
strong linear relationship between the mean reflectivity and the ice cloud
depth. Due to various synoptic circumstances, the ice clouds in summer are
warmer, higher and thicker, with larger reflectivity than that in winter;
in particular, the mean cloud-top height of ice clouds in summer is 2.2 km
higher than that in winter. Our analysis indicates that in spring, in situ-origin
cirrus clouds are more common than liquid-origin cirrus clouds, while in summer
liquid-origin cirrus clouds are more frequent; in autumn and winter, most cirrus
clouds are of in situ origin.
Including informal housing in slope stability analysis – an application to a data-scarce location in the humid tropics
Authors: Bozzolan Elisa , Holcombe Elizabeth , Pianosi Francesca , Wagener Thorsten 
Published: November 2020

Abstract. Empirical evidence from the humid tropics shows that informal housing can
increase the occurrence of rainfall-triggered landslides. However, informal
housing is rarely accounted for in landslide hazard assessments at community or larger scales. We include informal-housing influences (vegetation removal, slope cutting, house loading, and point water sources) in a slope stability analysis. We extend the mechanistic model CHASM (Combined Hydrology and Stability Model) to include leaking pipes, septic tanks, and roof gutters. We apply this extended model (CHASM+) in a region of the humid tropics using a stochastic framework to account for uncertainties related to model parameters and drivers (including climate change). We find slope cutting to be the most detrimental construction activity for slope stability, and we quantify its influence and that of other destabilising factors. When informal housing is present, more failures (+85 %) are observed in slopes that would otherwise have had low landslide susceptibility and for high-intensity, short-duration precipitations. As a result, the rainfall threshold for triggering landslides is lower when compared to non-urbanised slopes and comparable to those found empirically for similar urbanised regions. Finally, low cost-effective “low regrets” mitigation actions are suggested to tackle the main landslide drivers identified in the study area. The proposed methodology and rainfall threshold calculation are suitable for data-scarce contexts, i.e. when limited field measurements or landslide inventories are available.

On Equilibria Stability in an Epidemiological SIR Model with Recovery-dependent Infection Rate
Authors: Baez Sanchez A. D. , Bobko N. 
Published: November 2020

We consider an epidemiological SIR model with an infection rate depending on the recovered population. We establish sufficient conditions for existence, uniqueness, and stability (local and global) of endemic equilibria and consider also the stability of the disease-free equilibrium. We show that, in contrast with classical SIR models, a system with a recovery-dependent infection rate can have multiple endemic stable equilibria (multistability) and multiple stable and unstable saddle points of equilibria. We establish conditions for the occurrence of these phenomena and illustrate the results with some examples.

Les intrigues carnavalesques, « mi-carêmes » ou « mascarades ». Étude croisée en Europe et Amérique francophones
Authors: Lempereur Françoise 
Published: November 2020

En Europe comme en Amérique francophones, les intrigues carnavalesques ne perdurent que dans quelques villages ou petites villes qui ont gardé une population assez homogène : des masqués pénètrent dans les maisons dont ils connaissent les occupants et rappellent, sur un mode humoristique ou satirique, des anecdotes ou des situations personnelles relatives à leurs « hôtes ». Ils déguisent leur voix afin de tenir le plus longtemps possible avant d’être reconnus. Agacées, les personnes visées tentent, dans la bonne humeur, de les démasquer en offrant à boire. L’auteure a dépouillé la littérature sur le sujet et a personnellement observé la pratique, qu’elle décrit et analyse en alliant méthodologie ethnographique et réflexion socio-politique.
Un corpus nommé désir : le laboratoire d’étonnement pour réintroduire l’affect dans la recherche
Authors: Collin-Vallée Tommy , Merri Maryvonne 
Published: November 2020

Cette contribution présente les fondements d’un laboratoire d’étonnement comme moyen méthodologique de transformer un objet de déception en objet de désir pour le chercheur. Tout d’abord, les auteurs proposent une lecture spinoziste de leurs émotions causées par leur confrontation avec un matériau étranger au domaine de la psychologie, un docu-feuilleton sur le décrochage scolaire intitulé « Les persévérants » (Ferron et Baer, 2014). Ils considèrent l’étonnement comme un affect pour renouveler l’intérêt du chercheur pour son sujet de recherche. Ils en examinent ensuite les conditions d’émergence. Enfin, les conditions de mise en place d’un laboratoire d’étonnement sont illustrées par des exemples tirés de la littérature et des pratiques des auteurs.
L’évolution d’une posture de recherche : le soutien par l’analyse en mode écriture
Authors: Gremion François 
Published: November 2020

Ce texte relate l’évolution de la posture de chercheur de l’auteur au cours de la réalisation de sa thèse de doctorat et son lien avec le choix d’une démarche d’analyse. Incidemment, ce récit comporte les dimensions d’une recherche autobiographique. Ce texte illustre comment, dans le cadre d’une thèse, l’auteur a mis en oeuvre un lent processus évolutif de sa posture de chercheur grâce au moyen d’une démarche d’analyse en mode écriture. Un retour à l’écriture manuscrite, considérée ici comme une ficelle d’analyste, a permis le déploiement de la pensée nécessaire à la conceptualisation et à la transformation de son « soi » professionnel et personnel au travers d’une méthode d’analyse se déroulant en cinq temps, de la transcription à la rédaction finale du rapport.
À la recherche du monde vécu
Authors: Veillette Sylviane , Merri Maryvonne 
Published: November 2020

Cet article apporte une vision critique de la transposition didactique de l’approche dominante de la psychologie, étendue aujourd’hui à la psychologie de l’éducation. D’abord, nous présentons les principes scientifiques retenus dans la formation en psychologie. Ces principes concernent la notion de participant, les objets de recherche privilégiés et l’activité du chercheur. Nous montrons, à la suite d’Habermas (1987), que cette psychologie participe à une « colonisation du monde vécu » et à un rétrécissement historico-culturel de celui-ci. Nous proposons enfin une alternative épistémologique et méthodologique permettant une relecture de ces trois principes dans une perspective historico-culturelle.

Published: November 2020

Background
Secondary fungal metabolites are important sources for new drugs against infectious diseases and cancers.

Methods
To obtain a library with enough diversity, we collected about 2,395 soil samples and 2,324 plant samples from 36 regions in Africa, Asia, and North America. The collection areas covered various climate zones in the world. We examined the usability of the global fungal extract library (GFEL) against parasitic malaria transmission, Gram-positive and negative bacterial pathogens, and leukemia cells.

Results
Nearly ten thousand fungal strains were isolated. Sequences of nuclear ribosomal internal transcribed spacer (ITS) from 40 randomly selected strains showed that over 80% were unique. Screening GFEL, we found that the fungal extract from Penicillium thomii was able to block Plasmodium falciparum transmission to Anopheles gambiae, and the fungal extract from Tolypocladium album was able to kill myelogenous leukemia cell line K562. We also identified a set of candidate fungal extracts against bacterial pathogens.
A Three in One Strategy to Achieve Zirconium Doping, Boron Doping, and Interfacial Coating for Stable LiNi0.8Co0.1Mn0.1O2 Cathode

AbstractLiNi0.8Co0.1Mn0.1O2 cathodes suffer from severe bulk structural and interfacial degradation during battery operation. To address these issues, a three in one strategy using ZrB2 as the dopant is proposed for constructing a stable Ni‐rich cathode. In this strategy, Zr and B are doped into the bulk of LiNi0.8Co0.1Mn0.1O2, respectively, which is beneficial to stabilize the crystal structure and mitigate the microcracks. Meanwhile, during the high‐temperature calcination, some of the remaining Zr at the surface combined with the surface lithium source to form lithium zirconium coatings, which physically protect the surface and suppress the interfacial phase transition upon cycling. Thus, the 0.2 mol% ZrB2‐LiNi0.8Co0.1Mn0.1O2 cathode delivers a discharge capacity of 183.1 mAh g−1 after 100 cycles at 50 °C (1C, 3.0–4.3 V), with an outstanding capacity retention of 88.1%. The cycling stability improvement is more obvious when the cut‐off voltage increased to 4.4 V. Density functional theory confirms that the superior structural stability and excellent thermal stability are attributed to the higher exchange energy of Li/Ni exchange and the higher formation energy of oxygen vacancies by ZrB2 doping. The present work offers a three in one strategy to simultaneously stabilize the crystal structure and surface for the Ni‐rich cathode via a facile preparation process.

AbstractObjectivesVariation in trabecular and cortical bone properties is often used to infer habitual behavior in the past. However, the structures of both types of bone are rarely considered together and may even contradict each other in functional interpretations. We examine trabecular and cortical bone properties in various athletes and sedentary controls to clarify the associations between combinations of cortical and trabecular bone properties and various loading modalities.Materials and methodsWe compare trabecular and cortical bone properties using peripheral quantitative computed tomography scans of the tibia between groups of 83 male athletes (running, hockey, swimming, cricket) and sedentary controls using Bayesian multilevel models. We quantify midshaft cortical bone rigidity and area (J, CA), midshaft shape index (Imax/Imin), and mean trabecular bone mineral density (BMD) in the distal tibia.ResultsAll groups show unique combinations of biomechanical properties. Cortical bone rigidity is high in sports that involve impact loading (cricket, running, hockey) and low in nonimpact loaded swimmers and controls. Runners have more anteroposteriorly elliptical midshafts compared to other groups. Interestingly, all athletes have greater trabecular BMD compared to controls, but do not differ credibly among each other.DiscussionResults suggest that cortical midshaft hypertrophy is associated with impact loading while trabecular BMD is positively associated with both impact and nonimpact loading. Midshaft shape is associated with directionality of loading. Individuals from the different categories overlap substantially, but group means differ credibly, suggesting that nuanced group‐level inferences of habitual behavior are possible when combinations of trabecular and cortical bone are analyzed.
The Generalized Uncertainty Principle
Authors: Li Jun‐Li , Qiao Cong‐Feng 
Published: November 2020

AbstractThe uncertainty principle lies at the heart of quantum physics, and is widely thought of as a fundamental limit of the measurement precision of incompatible observables. Here it is shown that the traditional uncertainty relation in fact belongs to the leading order approximation of a generalized uncertainty relation. That is, the leading order linear dependence of observables gives the Heisenberg type of uncertainty relations, while higher order nonlinear dependence may reveal more different and interesting correlation properties. Applications of the generalized uncertainty relation and the high order nonlinear dependence between observables in quantum information science are also discussed.

Published: November 2020

AbstractA new approach for one‐stage facile membrane modification during non‐solvent induced phase separation (NIPS)‐process is proposed. The novelty of this study is that cheap and commercially available anionic high molecular polyacrylamide‐based flocculant (AHMPF) is applied for the first time as an additive to coagulation bath (CB). The series of polyethersulfone membranes were prepared using 0.05–0.3 wt% AHMPF aqueous solution as CB at different temperatures (25–50°C) via NIPS. The effect of AHMPF concentration on the structure, composition and hydrophilicity of membranes was investigated. The separation and antifouling performance were evaluated during filtration of bovine serum albumin (BSA) solution and thermomechanical pulp mills process water (ThMP) in order to concentrate hemicellulose. The successful immobilization of AHMPF into the structure of membranes selective layer (not bottom layer) was confirmed by FTIR spectroscopy. It was established that despite the similar rejection of hemicellulose (88.8–93%) and lignin (20–21.4), modified membranes demonstrate 3–8 times higher flux and 2 times higher FRR (43.8% for reference membrane and 86.5% for modified one) in ThMP ultrafiltration. The developed membrane was found to be highly efficient in hemicellulose concentration and purification in pulp industry.
