Les frigos collectifs
Authors: Bherer Laurence , Lelièvre Agathe 
Published: September 2023

Cet article rend compte de l’émergence d’une pratique discrète de gestion des surplus alimentaires : le stockage et la redistribution depuis les frigos collectifs. Pour ce faire, il s’appuie sur une enquête ethnographique conduite entre 2016 et 2020 dans les villes de Montréal et de Québec. Il montre que ces pratiques s’insèrent dans les interstices du circuit classique de redistribution alimentaire pour proposer une gestion alternative des surplus. Les frigos n’opèrent toutefois pas en rupture avec le modèle des banques alimentaires mais plutôt en complémentarité, car ils offrent, à plus petite échelle, une avenue de plus pour disposer des surplus produits par l’industrie alimentaire. Aussi, c’est surtout dans le rapport aux donataires que les frigos apparaissent s’inscrire dans une pratique alternative. Avec le temps, ces frigos se révèlent néanmoins fragiles et tendent à disparaître ou à se formaliser.
Démocratie alimentaire et approches sensibles dans la transition écologique
Authors: Granchamp Laurence , Lamine Claire , Berthomé Guy El Karim , Tuscano Martina , Jenatton Morgan 
Published: September 2023

Cet article interroge la place accordée aux dimensions sensibles (au sens d’attachement, de ce qui « fait sens », ce à quoi l’on tient) ainsi que leur rôle au sein des dispositifs et expérimentations qui visent la transition écologique dans et par les systèmes alimentaires, à travers six cas situés dans différentes régions de France. Plus précisément, il sonde ces attachements afin de voir ce qu’ils peuvent apporter à la participation de publics à première vue éloignés des enjeux de transition écologique, et en explore la portée en matière de politisation. Il montre que la prise en compte de ces attachements offre un contrepoint aux approches technicistes et normatives de la transition écologique, tout en permettant de traiter les enjeux de la démocratie et de la justice alimentaires. Il identifie trois voies de politisation, diversement combinées dans les six expérimentations étudiées : la capacitation/l’augmentation du pouvoir d’agir (empowerment), la valorisation des pratiques et/ou des savoirs, et la formation de collectifs. Il suggère, enfin, qu’en dépit des limites que nous identifions, la prise en compte de ces dimensions sensibles favorise, sous certaines conditions, l’inclusion et la participation de ces publics. Cette prise en compte offre en outre une voie privilégiée pour l’articulation des enjeux de justice et de démocratie alimentaires aux enjeux environnementaux, ce qui mériterait d’être davantage considéré ou du moins discuté dans le cadre des politiques de transition écologique.
Temporal variation of the relationships between rice yield and climate variables since 1925
Authors: Chen Hungyen , Wu Yi-Chien , Teng Chih-Yung 
Published: September 2023

Background
Long-term time-series datasets of crop yield and climate variables are necessary to study the temporal variation of climate effects on crops. The aim of this study was to broadly assess assessment of the effects of climate on rice, and the associated temporal variations of the effects during the long-term period.

Methods
We conducted field experiments in Taiwan from 1925 to 2019 to collect and analyze rice yield data and evaluate the impacts of changes in average temperature, diurnal temperature range (DTR), rainfall, and sunshine duration on rice yield during cool and warm cropping seasons. We then estimated the relationships between annual grain yield and the climate variables using the time series of their first difference values. We also computed the total relative and annual actual yield changes using regression coefficients for each climate variable for the intervals 1925–1944, 1945–1983, and 1996–2019 to reveal the impacts of climate change on yields and the associated temporal variations during the overall experimental period.

Results
The annual daily average temperature calculated from the trend of the regression lines increased by 0.94–1.03 °C during the 95-year period. The maximum temperature remained steady while the minimum temperature increased, leading to decreased DTR. The total annual rainfall decreased by 237–352 mm and the annual total sunshine duration decreased by 93.9–238.9 h during the experimental period. We observed that during the cool cropping season, yield response to temperature change decreased, while that to DTR and rainfall changes increased. During the warm cropping season, all the yield responses to temperature, DTR, and rainfall changes were negative throughout the experimental period. In recent years (1996–2019) the estimated annual actual rice yield changes during the cool cropping season were negatively affected by climate variables (except for sunshine duration), and slightly positively affected (except for temperature) during the warm cropping season. Compared to the effects of temperature and DTR, those of rainfall and sunshine duration on rice yield changes were weak. This study contributes to provide impacts of climate change on rice yield and associated long-term temporal variations over nearly a century.
Photobleaching of pink photoluminescence in bandicoot fur
Authors: Reinhold Linda M. 
Published: September 2023

ABSTRACT
Bright pink-orange-red photoluminescent (fluorescent and/or phosphorescent) fur is being found in an increasing number and diversity of mammal species. With the molecules causing these colours of photoluminescent emission suspected to be mostly photosensitive porphyrins, degradation from light exposure is an unquantified contributor to false negatives in museum-based surveys. I tested the resistance of pink photoluminescent bandicoot, Peramelidae, fur to exposure to natural sunlight and artificial laboratory lighting. Photoluminescence underwent visibly noticeable photobleaching in two minutes of direct sun exposure, or a few hours when exposed to indoor lighting. The fleeting nature of porphyrins means that an accurate representation of pink-orange-red photoluminescence should not be expected in specimens that have been exposed to light, whether in life, post-mortem, during taxidermy or on display.

AbstractAt the intersection of synthetic biology and materials science, engineered living materials (ELMs) exhibit unprecedented potential. Possessing unique “living” attributes, ELMs represent a significant paradigm shift in material design, showcasing self‐organization, self‐repair, adaptability, and evolvability, surpassing conventional synthetic materials. This review focuses on reviewing the applications of ELMs derived from bacteria, fungi, and plants in environmental remediation, eco‐friendly architecture, and sustainable energy. The review provides a comprehensive overview of the latest research progress and emerging design strategies for ELMs in various application fields from the perspectives of synthetic biology and materials science. In addition, the review provides valuable references for the design of novel ELMs, extending the potential applications of future ELMs. The investigation into the synergistic application possibilities amongst different species of ELMs offers beneficial reference information for researchers and practitioners in this field. Finally, future trends and development challenges of synthetic biology for ELMs in the coming years are discussed in detail.
Segmentation of plant residues on soil X‐ray CT images using neural network
Authors: Valdes‐Korovkin Ilya , Fomin Dmitry , Yudina Anna 
Published: September 2023

AbstractIn soil, plant residues have low contrast making them difficult to detect using X‐ray computed tomography. In this work, we tested a convolutional neural network (U‐Net) for its ability to improve the identification of crop residues in soil samples assembled from aggregates of different size fractions (small, large, water‐stable aggregates, and average aggregate composition). Soil CT images were obtained using a 244 μm resolution. About 2500 soil images were annotated to train the neural network, of which only 631 images were selected for the training data set. Intersection over Union (IOU) was used as a measure of success of segmentation by neural network, which takes values from 0 to 1. In the validation data set, IOU of background was 0.93, IOU of solid phase was 0.95, IOU of pore space was 0.77, and IOU of plant residues was 0.40. However, IOU of plant residues in the total data set increased to 0.7. Soil structure influences the quality of multiphase segmentation of soil CT images. The poorest segmentation of plant residues was in the soil samples composed of average aggregate size composition. The quality of pore space segmentation increased with increasing porosity of the soil sample. The model tends to generalize the large areas occupied by plant residues and overlooks the smaller ones. The low values of the IOU metric for plant residues in the training data set can also be related to insufficient quality of annotation of the original images.
Synthesis towards Phainanoid F: Photo‐induced 6π‐Electrocyclization for Constructing Contiguous All‐Carbon Quaternary Centers

Published: September 2023

AbstractIn this paper, we report an efficient strategy for synthesizing the DEFGH rings of phainanoid F. The key to the construction of the 13,30‐cyclodammarane skeleton of the molecule was a photo‐induced 6π‐electrocyclization and a homoallylic elimination. Notably, this is a rare example of using electrocyclization reaction to simultaneously construct two vicinal quaternary carbons in total synthesis. The strategy outlined here forms the basis of our total synthesis of Phainanoid F, and it could also serve as a generally applicable approach for synthesizing other natural products containing similar 13,30‐cyclodammarane skeletons.
High‐Rate Discharge Minimizes Volume Expansion of Lithium Metal Electrodes under Lean Electrolyte and High Areal Capacity Conditions

Published: September 2023

AbstractThe demand for practical implementation of lithium metal batteries (LMBs) is increasing due to their superior energy density. However, poor cycle life and safety concerns regarding dendrite formation remain significant challenges. Recent studies have shown empirical improvements in cycle life through the use of high‐rate discharge protocols, but the precise mechanism behind this enhancement is still unclear due to difficulties in analyzing the lithium electrode, especially in LMB cells with high energy density designs. In this study, X‐ray computed tomography (XCT) analysis, a non‐destructive technique, was employed to investigate the lithium metal electrode in pouch‐type cells with a cell‐level energy density exceeding 350 Wh kg−1. XCT analysis revealed significant volume expansion of the lithium electrode during charge/discharge cycles, particularly under high‐rate charging conditions, which promoted dendritic growth due to inhomogeneous current distribution. However, such undesired volume expansion was largely suppressed during high‐rate discharge, leading to improved cycle life. This study underscores the importance of non‐destructive techniques in comprehending the degradation mechanisms of high‐energy‐density LMBs.
Unravelling the interplay of local structure and valence transitions in Ce‐doped CaYAlO4 luminescent materials
Authors: Sun Wenhao , Liu Zihui , Xu Zhipeng , Zhang Yang 
Published: September 2023

AbstractCerium has been widely used as a dopant in luminescent materials due to its unique electronic configurations. It is generally anticipated that the luminescence properties of rare‐earth‐doped materials are closely related to the local environment of activators, especially for Ce3+. In addition, it is convenient to modulate its emission wavelength by adjusting the composition and structure. In this study, we systematically analyzed the microstructure of the Ce‐doped CaYAlO4 system at atomic resolution. The quantitive results indicated that the structure distortion greatly influenced the valence state of the Ce dopant, which is critical to its luminescence efficiency. In addition, valence variations also exist from surface to inner structure due to the big distortion area around the surface. Our results unravel the interplay of local structure and valence transitions in Ce‐doped aluminate phosphors, which has the potential to be applied in other luminescent materials.

AbstractBackgroundRecently, chemotherapy plus immunotherapy has achieved remarkable efficacy in lung squamous cell carcinoma (LUSC). However, some patients, especially frail people, cannot tolerate full‐dose chemotherapy in the real world. To reduce toxicity, appropriate dose reduction in chemotherapy is necessary. Therefore, this study aimed to demonstrate the efficacy and safety of reduced‐dose chemotherapy plus immunotherapy in LUSC patients in the real world.MethodsA real‐world observational study was conducted concerning patients who received chemotherapy plus immunotherapy in our situation. The primary endpoints were objective response rate (ORR) and disease control rate (DCR), and the secondary endpoints were progression‐free survival (PFS), overall survival (OS), and toxicity.ResultsBetween December 2018 and January 2022, 110 patients were enrolled, of whom 54 patients were chemotherapy reduced‐dose group and 56 patients were chemotherapy standard‐dose group. The ORR in the reduced‐dose group is similar to standard‐dose group (85.19% vs. 71.43%, p = 0.082). Similar DCR were observed (100% vs. 94.64%, p = 0.086). Median PFS was 12 months in the reduced‐dose group and standard‐dose group, respectively. Median OS was 15 months and 16 months in the reduced‐dose group and standard‐dose group, respectively. We reported a lower incidence of grade 3–4 toxicity in the reduced‐dose group compared with standard‐dose group (27.78% vs. 42.86%, p = 0.100). The major toxic reactions were better alleviated in the reduced‐dose group than in the standard‐dose group, especially in the thrombocytopenia (p = 0.044), peripheral nerve damage (p = 0.001), gastrointestinal reactions (p < 0.0001), and fatigue (p = 0.001).ConclusionsThe modified regimen with attenuated doses of chemotherapy in combination with immunotherapy was effective and well tolerated in patients with LUSC. The efficacy of this modified regimen is similar to that of the full‐dose regimen.

AbstractMacrocyclization reactions are still challenging due to competing oligomerization, which requires the use of small substrate concentrations. Here, the cationic tungsten imido and tungsten oxo alkylidene N‐heterocyclic carbene complexes [[W(N‐2,6‐Cl2‐C6H3)(CHCMe2Ph(OC6F5)(pivalonitrile)(IMes)+ B(ArF)4−] (W1) and [W(O)(CHCMe2Ph(OCMe(CF3)2)(IMes)(CH3CN)+ B(ArF)4−] (W2) (IMes=1,3‐dimesitylimidazol‐2‐ylidene; B(ArF)4−=tetrakis(3,5‐bis(trifluoromethyl)phenyl borate) have been immobilized inside the pores of ordered mesoporous silica (OMS) with pore diameters of 3.3 and 6.8 nm, respectively, using a pore‐selective immobilization protocol. X‐ray absorption spectroscopy of W1@OMS showed that even though the catalyst structure is contracted due to confinement by the mesopores, both the oxidation state and structure of the catalyst stayed intact upon immobilization. Catalytic testing with four differently sized α,ω‐dienes revealed a dramatically increased macrocyclization (MC) and Z‐selectivity of the supported catalysts compared to the homogenous progenitors, allowing high substrate concentrations of 25 mM. With the supported complexes, a maximum increase in MC‐selectivity from 27 to 81 % and in Z‐selectivity from 17 to 34 % was achieved. In general, smaller mesopores exhibited a stronger confinement effect. A comparison of the two supported tungsten‐based catalysts showed that W1@OMS possesses a higher MC‐selectivity, while W2@OMS exhibits a higher Z‐selectivity which can be rationalized by the structures of the catalysts.

Published: September 2023

AbstractThe Face Name Associative Memory Exam (FNAME) was introduced into the NIH Toolbox as part of the ARMADA study and establishes normative data for diverse participants, ages 64 to 85+, and proposes cutoff scores between biomarker positive versus negative (+/−) groups. The FNAME was administered to 257 participants across the clinical spectrum with 122 having amyloid biomarkers. Linear regression explored the association between demographics and FNAME and between amyloid (+/−) groups. Receiver operating characteristic curves (ROC) identified performance thresholds that best discriminated between biomarker (+/−) individuals. Lower FNAME scores occurred in males, older ages, Black/African Americans, Hispanics, and biomarker‐positive participants. ROC analyses demonstrated acceptable accuracy (0.73 to 0.77) but only when combined with clinical status. The diagnostic discrimination of amyloid positivity was acceptable but not excellent, suggesting the FNAME may be a better screening indicator of clinical status rather than amyloid deposition in cognitively normal individuals. Normative data are provided.

Published: September 2023

AbstractThe self‐assembly of block copolymers (BCPs) within emulsion droplets is a flexible strategy for the preparation of polymer particles. This strategy permits the fine‐tuning of shapes, internal structures, and surface nanostructures of the polymer particles, thus allowing many applications. Although some literature has reviewed the BCP preparation via self‐assembly within a droplet, a comprehensive summary including in‐depth understanding, controllable preparation, and application is lacked. In this review, we systematically delve into the multiple mechanisms that drive BCP self‐assembly within emulsion droplets, such as commensurability effects for minimizing total free energy, interfacial instability, organized spontaneous emulsification, phase separation of multiple components, and entropy effects between BCPs and nanoparticles. Additionally, a strategy combining selective cross‐linking and disassembly can further generate Janus particles featuring unique structures. Next, various applications across multiple disciplines are discussed, including drug delivery, display, biomedical imaging, macromolecular separation, and fuel cells. Finally, we present an overview of the current challenges and future directions for BCP emulsion self‐assembly, covering mechanism investigation, molecular design, stability control, and application exploration. We anticipate deeper understanding, more varieties, enhanced performance, and broader applications can be achieved with BCP emulsion self‐assembly after addressing the challenge.
A review on flaxseeds: Nutritional profile, health benefits, value added products, and toxicity

Published: September 2023

AbstractFlaxseed has been consumed by people for a very long time due to its nutritional value and medicinal applications. In India, flaxseed is used for both culinary and medicinal reasons. About 45% of alpha‐linolenic acid (ALA), 28%–30% protein, and 35% fiber are present in flaxseeds. The finest source of omega‐3 fatty acids for those who do not consume seafood is flaxseed. Flaxseeds have lignin, of which primary lignan is secoisolariciresinol diglycoside, with low amounts of isolariciresinol, lariciresinol, pinoresinol, and matairesinol. Flaxseed is probably safe for most grown‐ups. The daily number of bowel movements may increase if flaxseed is included in the diet. Additionally, it may result in side effects such as gas, bloating, stomach pain, and nausea. Higher dosages are probably going to cause more secondary effects. Due to the nutritional profile of flaxseeds, they exhibit various health benefits which include; improving cardiac health, improving brain development, improving skin health, improving gut health, maintaining blood sugar level, reducing the risk of renal diseases, and several types of cancers. The purpose of this study is to provide a general overview of the nutritional profile, health benefits, value‐added products, and toxicity of flaxseeds.
