Malgré une ouverture et une démocratisation croissante des données satellitaires et outils de traitement associés, l’utilisation de ces données et des informations qui en sont issues reste relativement limitée dans les pays du Sud. Depuis plusieurs années, des initiatives visant l’amélioration de l’accès et de l’utilisation par les acteurs locaux ont vu le jour. Ce papier présente le bilan de 3 projets successifs financés par l’Agence Française de Développement en Afrique Centrale et de l’Ouest entre 2010 et 2020. Ces projets, pilotés par IGN FI et l’Institut de Recherche pour le Développement (IRD), ont apporté des éléments de réponse aux principaux défis identifiés par les acteurs locaux partenaires tels que : l’accès aux données, l’amélioration des compétences pour le traitement des données, la sensibilisation des décideurs et gestionnaires des territoires aux informations et services qui peuvent en être dérivés, la production par des équipes locales de cartographie de référence ou encore la montée en compétence et la structuration de réseaux d’utilisateurs. Cet article reprend les actions et résultats sur trois axes d’intervention à savoir (i) la mise à disposition gratuite de données récentes à haute résolution, (ii) la production locale de cartographie de l’évolution du couvert forestier et de l’occupation du sol et (iii) la promotion de l’utilisation des images par des actions de formation et d’animation scientifique. Les résultats de plusieurs projets appuyés dans le cadre de ces actions font l’objet de publications dans ce numéro spécial Afrique.

Nisitrus Saussure, 1878 is a diurnal and monophyletic group of eneopterine crickets found in parts of Southeast Asia. Species often have vivid colourations which make them charismatic photograph subjects among macro photographers. However, their taxonomy has not been revised since their original descriptions, whereas there are also species awaiting to be discovered and described. A synoptic revision is therefore needed prior to studying the phylogenetic relationships of the genus, and before undertaking more precise studies on biogeography and evolution of traits. By holistically incorporating information about general morphology, male and female genitalia, and bioacoustics, we revise the taxonomy of these crickets and recognise 10 valid species of Nisitrus. Five new species are described: N. crucius Robillard & Tan sp. nov. from Borneo; N. danum Robillard & Tan sp. nov. from Borneo; N. hughtani Robillard & Tan sp. nov. from Sumatra; N. malaya Robillard & Tan sp. nov. from Malay Peninsula; and N. rindu Robillard & Tan sp. nov. from Borneo. We redescribe N. brunnerianus and N. insignis; describe the calls of N. malaya sp. nov., N. musicus and N. vittatus. We consider N. sumatrensis as a junior synonym of N. insignis; and N. marginata as a junior synonym of N. vittatus. Nisitrus hyalinus requires further revision. We also consider N. maculosus as a dubious name.

AbstractPurposeThe integration of auto‐segmentation and automated treatment planning methods on a fast‐rotating O‐ring linac may improve the time efficiency of online adaptive radiotherapy workflows. This study investigates whether automated treatment planning of prostate SBRT with focal boosting on the O‐ring linac could generate plans that are of similar quality as those obtained through manual planning on clinical C‐arm linacs.MethodsFor 20 men with prostate cancer, reference treatment plans were generated on a TrueBeam STx C‐arm linac with HD120 MLC and a TrueBeam C‐arm linac with Millennium 120 MLC using 6 MV flattened dual arc VMAT. Manual planning on the Halcyon fast‐rotating O‐ring linac was performed using 6 MV FFF dual arc VMAT (HA2‐DL10) and triple arc VMAT (HA3‐DL10) to investigate the performance of the dual‐layer MLC system. Automated planning was performed for triple arc VMAT on the Halcyon linac (ET3‐DL10) using the automated planning algorithms of Ethos Treatment Planning. The prescribed dose was 35 Gy to the prostate and 30 Gy to the seminal vesicles in five fractions. The iso‐toxic focal boost to the intraprostatic tumor nodule(s) was aimed to receive up to 50 Gy. Plan deliverability was verified using portal image dosimetry measurements.ResultsCompared to the C‐arm linacs, ET3‐DL10 shows increased seminal vesicles PTV coverage (D99%) and reduced high‐dose spillage to the bladder (V37Gy) and urethra (D0.035cc) but this came at the cost of increased high‐dose spillage to the rectum (V38Gy) and a higher intermediate dose spillage (D2cm). No statistically significant differences were found when benchmarking HA2‐DL10 and HA3‐DL10 with the C‐arm linacs. All plans passed the patient‐specific QA tolerance limit.ConclusionsAutomated planning of prostate SBRT with focal boosting on the fast‐rotating O‐ring linac is feasible and achieves similar plan quality as those obtained on clinical C‐arm linacs using manual planning.

Published: July 2021

AbstractDielectric capacitors are widely studied for power supply systems because they can quickly store and release electrical energy. Among various kinds of dielectric materials, antiferroelectrics show promising features of high energy‐storage density and efficiency. In this study, epitaxial antiferroelectric PbHfO3 films with different orientations are fabricated, in which remarkable anisotropies of polarization and energy storage properties are discovered. With the optimization of film orientation, much‐improved energy density and excellent high‐temperature efficiency are achieved in the PbHfO3 films. Moreover, the PbHfO3 films are fabricated onto flexible mica substrates, which exhibit excellent property robustness against mechanical bending. This study provides a fundamental understanding of the anisotropic antiferroelectric behaviors of epitaxial PbHfO3 films and provides a generalizable pathway for flexible energy‐storage dielectric capacitors.
Modification of the Enantioselectivity of Biocatalytic meso‐Desymmetrization for Synthesis of Both Enantiomers of cis‐1,2‐Disubstituted Cyclohexane by Amidase Engineering

Published: July 2021

AbstractBoth enantiomers of cis‐1,2‐disubstituted cyclohexane have been obtained enantioselectively through engineered amidase‐catalyzed desymmetrization of meso carbocyclic 1,2‐dicarboxamides under mild condition. Based on the enzyme‐substrate binding model suggested by molecular docking, the amplification and reversal of enantioselectivity of amidase was quickly achieved through generating and testing only 8 variants. The origin of enantiopreference for amidase was revealed by MD simulations and the reason for the reversal of enantioselectivity towards amidase variant was disclosed. The synthetic application of biocatalytic meso‐desymmetrization was demonstrated by straightforward transformation of the products to enantiomerically pure heterocyclic compounds.magnified image
Multi‐Resonance Deep‐Red Emitters with Shallow Potential‐Energy Surfaces to Surpass Energy‐Gap Law**

AbstractEfficient organic emitters in the deep‐red region are rare due to the “energy gap law”. Herein, multiple boron (B)‐ and nitrogen (N)‐atoms embedded polycyclic heteroaromatics featuring hybridized π‐bonding/ non‐bonding molecular orbitals are constructed, providing a way to overcome the above luminescent boundary. The introduction of B‐phenyl‐B and N‐phenyl‐N structures enhances the electronic coupling of those para‐positioned atoms, forming restricted π‐bonds on the phenyl‐core for delocalized excited states and thus a narrow energy gap. The mutually ortho‐positioned B‐ and N‐atoms also induce a multi‐resonance effect on the peripheral skeleton for the non‐bonding orbitals, creating shallow potential energy surfaces to eliminate the high‐frequency vibrational quenching. The corresponding deep‐red emitters with peaks at 662 and 692 nm exhibit narrow full‐width at half‐maximums of 38 nm, high radiative decay rates of ca. 108 s−1, ≈100 % photo‐luminescence quantum yields and record‐high maximum external quantum efficiencies of ca. 28 % in a normal planar organic light‐emitting diode structure, simultaneously.

Published: July 2021

AbstractA reinvestigation of the linalool synthase from Chryseobacterium polytrichastri uncovered its diterpene synthase activity, yielding polytrichastrene A and polytrichastrol A with new skeletons, besides known wanju‐2,5‐diene and thunbergol. The enzyme mechanism was investigated by isotopic labeling experiments and DFT calculations to explain an unusual ethyl group formation. Rationally designed exchanges of active site residues showed major functional switches, resulting for I66F in the production of five more new compounds, including polytrichastrene B and polytrichastrol B, while A87T, A192V and the double exchange A87T, A192V gave a product shift towards wanju‐2,5‐diene.

AbstractLow dielectric photoactive materials have significant potential as components in future microelectronics. Although a number of photosensitive groups have been used to construct photopatternable materials, it remains challenging to introduce these groups into polymer chains via facile yet controlled polymerization techniques. The present work demonstrates the synthesis of a new class of photoactive cyclosiloxane monomers having hybrid siloxane‐carbosilane main chains. These compounds can be cured by applying ultraviolet radiation and heat to promote the reaction of the silacyclobutene units and form hyper‐cross‐linked cyclosiloxanes. The cured resins show high thermal stability (with T5% values in the range of 460–550°C), low dielectric constants (2.36–2.76 at 10 MHz) and low dielectric losses (10−3 at 10 MHz). Thus, these polymers could possibly be used as high‐performance dielectric materials.

Published: July 2021

AbstractIn the framework of an archaeological prospection case study conducted at the Swedish Iron Age site of Uppåkra near Lund, a large number of anomalies caused by buried archaeological remains were detected using extensive magnetic surveys. Written sources report that the Swedish army under Field marshal Gustav Horn had established a camp near the village of Uppåkra in autumn 1644, awaiting the approaching Danish army. Magnetic anomalies of two large, square structures, numerous pits and several pit alignments have been interpreted as possible traces of buried remains of this army camp. We present archaeological prospection data from Uppåkra with regard to the events that took place during Horn's war in 1644.

AbstractIn situ chlorophyll a fluorescence measurements were applied to monitor changes in the photochemical variables of Nannochloropsis oceanica cultures under nitrogen‐deplete and nitrogen‐replete (control) conditions. In addition, growth, lipid, fatty acid, and pigment contents were also followed. In the control culture, growth was promoted along with pigment content, electron transport rate (ETR), and polyunsaturated fatty acids, while total lipid content and fatty acid saturation level diminished. Under nitrogen‐deplete conditions, the culture showed a higher de‐epoxidation state of the xanthophyll cycle pigments. Fast transients revealed a poor processing efficiency for electron transfer beyond QA, which was in line with the low ETR due to nitrogen depletion. Lipid content and the de‐epoxidation state were the first biochemical variables triggered by the change in nutrient status, which coincided with a 20% drop in the in situ effective quantum yield of PSII (ΔF’/Fm'), and a raise in the Vj measurements. A good correlation was found between the changes in ΔF’/Fm' and lipid content (r = −0.96, p < 0.01). The results confirm the reliability and applicability of in situ fluorescence measurements to monitor lipid induction in N. oceanica.

AbstractBackgroundTo use ddPCR to quantify plasma exosomal class III β‐tubulin (βIII‐tubulin, TUBB3, encoded by the TUBB3 gene) mRNA expression in metastatic castration‐resistant prostate cancer (mCRPC) patients, and study the association of this expression with abiraterone efficacy.MethodsBlood samples were prospectively collected from 52 mCRPC patients using abiraterone as first‐line therapy to measure plasma exosomal TUBB3 mRNA expression value before the initiation of abiraterone. Study endpoints were PSA response rate, PSA‐progression‐free survival (PSA‐PFS), and overall survival (OS, from CRPC to death).ResultsPatients with positive exosomal TUBB3 expression showed shorter PSA‐PFS (negative TUBB3 vs. positive TUBB3: 11.0 vs. 7.9 months; p = 0.014). Further analysis demonstrated that patients with strongly positive exosomal TUBB3 (>20 copies/20 µl) was associated with even shorter PSA‐PFS (negative TUBB3 vs. positive TUBB3 [<20 copies/20 µl] vs. strongly positive TUBB3 [>20 copies/20 µl]: 11.0 vs. 8.3 vs. 3.6 months, p = 0.005). In multivariate analyzes, TUBB3 (+) (HR: 2.114, p = 0.033) and ECOG score >2 (HR: 3.039, p = 0.006) were independent prognosticators of poor PSA‐PFS. PSA response and OS did not present significant differences.ConclusionThe exosomal TUBB3 mRNA expression level is associated with poor PSA‐PFS of abiraterone in mCRPC patients. The detection of exosomal TUBB3 can be valuable in their management.

Published: July 2021

AbstractObjectiveThis study aimed to illuminate developmental changes and gender differences in the link between weight concerns and cigarette use across adolescence. Specifically, we examined whether and how the strength of the association between weight concerns and cigarette use changed across adolescence, and whether patterns of association differed between boys and girls.MethodParticipants were 397 predominately White adolescents ages 11–18 years (50.5% female) from a longitudinal observational study conducted in the United States.ResultsTime‐varying effect modeling revealed that even after adjusting for BMI, the association between weight concerns and cigarette use was positive and significant for girls from age 11.3 to 15.9, with the strongest association at 12.7 years. For boys, this association was non‐significant throughout adolescence.DiscussionResults suggest a sensitive period in early‐ to mid‐adolescence during which girls with weight concerns may be at heightened risk for cigarette use. Findings have implications for the developmental timing of interventions to prevent cigarette use and weight concerns and suggest that tailored interventions for girls may be warranted.

Published: July 2021

AbstractThe first asymmetric total synthesis of the reported isostreptenol III 1 is accomplished in high overall yield starting from D‐ribose. Incompatible spectroscopic data of the synthetic isostreptenol III in comparison to that of the reported isolate led us to propose a revised structure 2. The structure of the isolated (3R,4S)‐isostreptenol III was revised to (3R,4R)‐isostreptenol III. The salient features of this synthesis are highly diastereoselective Wittig olefination, regioselective epoxide opening, and stereoselective installation of hydroxymethyl group dictated by the inherent cis‐stereochemistry of the acetonide group of the lactol derived from D‐ribose.

Published: July 2021

AbstractAs promising photovoltaic devices, perovskite solar cells (PSCs) have attracted extensive and ongoing attention due to easy manufacturing and high power conversion efficiency (PCE). Although the PCE is lower than that of PSCs with normal structure, inverted PSCs have been widely investigated due to their lower hysteresis and potential application. Electron transport layer (ETL) on top of perovskite film in inverted PSCs plays a significant role in device performance. Inorganic top ETL has been used to replace organic ETL for their excellent characters. This review summarizes the progress of inorganic top ETL for high‐performance inverted PSCs. Firstly, the principles of top ETL and advantages of inorganic ETL are highlighted. Then the established top ETLs are summarized. Subsequently, various strategies for top ETL fabrication are shown to demonstrate their advantages and shortcomings. Finally, conclusion and outlook of top ETL in inverted PSCs are presented, addressing the issues and directing the hopeful solutions.image
