The farm to fork strategy and the digital transformation of the agrifood sector—An assessment from the perspective of innovation systems
Authors: Reinhardt Tilman 
Published: March 2022

AbstractThe article assesses the European Union's Farm to Fork (F2F) strategy from the perspective of innovation systems, focusing on digital technologies in agriculture. It employs the Technical Innovation Systems framework to analyze how the policies proposed in the F2F strategy affect essential functions of the innovation system. The analysis shows that the F2F strategy significantly contributes to innovation system performance by providing a clear and coherent agenda and various concrete measures designed to support innovation, knowledge and skill development. However, the strategy falls short in creating favorable market conditions for innovative technologies and building legitimacy with farmers as the most important user group.

AbstractPremiseTrees in wet forests often have features that prevent water films from covering stomata and inhibiting gas exchange, while many trees in drier environments use foliar water uptake to reduce water stress. In forests with both wet and dry seasons, evergreen trees would benefit from producing leaves capable of balancing rainy‐season photosynthesis with summertime water absorption.MethodsUsing samples collected from across the vertical gradient in tall redwood (Sequoia sempervirens) crowns, we estimated tree‐level foliar water uptake and employed physics‐based causative modeling to identify key functional traits that determine uptake potential by setting hydraulic resistance.ResultsWe showed that Sequoia has two functionally distinct shoot morphotypes. While most shoots specialize in photosynthesis, the axial shoot type is capable of much greater foliar water uptake, and its within‐crown distribution varies with latitude. A suite of leaf surface traits cause hydraulic resistance, leading to variation in uptake capacity among samples.ConclusionsShoot dimorphism gives tall Sequoia trees the capacity to absorb up to 48 kg H2O h−1 during the first hour of leaf wetting, ameliorating water stress while presumably maintaining high photosynthetic capacity year round. Geographic variation in shoot dimorphism suggests that plasticity in shoot‐type distribution and leaf surface traits helps Sequoia maintain a dominate presence in both wet and dry forests.

AbstractThe severe performance degradation of high‐capacity Li−O2 batteries induced by Li dendrite growth and concentration polarization from the low Li+ transfer number of conventional electrolytes hinder their practical applications. Herein, lithiated Nafion (LN) with the sulfonic group immobilized on the perfluorinated backbone has been designed as a soluble lithium salt for preparing a less flammable polyelectrolyte solution, which not only simultaneously achieves a high Li+ transfer number (0.84) and conductivity (2.5 mS cm−1), but also the perfluorinated anion of LN produces a LiF‐rich SEI for protecting the Li anode from dendrite growth. Thus, the Li−O2 battery with a LN‐based electrolyte achieves an all‐round performance improvement, like low charge overpotential (0.18 V), large discharge capacity (9508 mAh g−1), and excellent cycling performance (225 cycles). Besides, the fabricated pouch‐type Li–air cells exhibit promising applications to power electronic equipment with satisfactory safety.
Vermittelnde Oxidation von Thioethern mit Iod – Eine vielseitige und milde Methode zur Bildung von Peptidhydrogelen

Published: March 2022

AbstractDie Entwicklung Redox‐ausgelöster Peptidhydrogele ist mit fundamentalen Herausforderungen verknüpft, da hoch spezifische Peptidarchitekturen benötigt werden, was unvermeidlich in einer Limitierung der Vielseitigkeit solcher Materialien resultiert. Ein vielversprechender, jedoch selten genutzter Ansatz, um diese Hürden zu überwinden, ist die Nutzung einer vermittelnden Redoxreaktion zur kontrollierten Absenkung des pH‐Werts während der Hydrogelbildung. Hier beschreiben wir eine vielseitige Strategie zum Auslösen der Gelierung von Hydrogelen bestehend aus leicht zugänglichen, Säure‐ausgelösten Gelatoren durch Freisetzung der dafür notwendigen Protonen über die Oxidation von Thioethern mit Iod. Durch Zugabe von Thiodiglycol als einfach verfügbarer Hilfstoff zur basischen Vorlösung des Peptidgelators Nap‐FF sowie weiteren Peptiden werden nach Vermischung mit Triiodid hocheffizient Hydrogele erhalten. Darüber hinaus ermöglicht der Einbau der Thioethereinheit in das Rückgrat des Gelators die Modulation des Ansatzes unter Reduktion der Anzahl der notwendigen Additive, wie gezeigt anhand des maßgeschneiderten Nap‐FMDM Gelators.

AbstractThis work describes the design and synthesis of a π‐conjugated telluro[3,2‐β][1]‐tellurophene‐based synthon that, embodying pyridyl and haloaryl chalcogen‐bonding acceptors, self‐assembles into nanoribbons through chalcogen bonds. The ribbons π‐stack in a multi‐layered architecture both in single crystals and thin films. Theoretical studies of the electronic states of chalcogen‐bonded material showed the presence of a local charge density between Te and N atoms. OTFT‐based charge transport measurements showed hole‐transport properties for this material. Its integration as a p‐type semiconductor in multi‐layered CuI‐based light‐emitting electrochemical cells (LECs) led to a 10‐fold increase in stability (38 h vs. 3 h) compared to single‐layered devices. Finally, using the reference tellurotellurophene congener bearing a C−H group instead of the pyridyl N atom, a herringbone solid‐state assembly is formed without charge transport features, resulting in LECs with poor stabilities (<1 h).
Archaeological site types, and assemblage size and diversity in Aotearoa New Zealand
Authors: Phillipps Rebecca , Holdaway Simon , Barrett Matthew , Emmitt Joshua 
Published: March 2022

AbstractArchaeological settlement models involve the identification of functional site types like base camps and extraction sites based, in part, on differences in the range and frequency of artefact types and fauna. Using reports describing such assemblages from Aotearoa (New Zealand) archaeological sites dating to the first 300 years after initial colonisation, differences in assemblage composition are assessed against total assemblage size. Aotearoa provides a particularly useful test case for the archaeological identification of site types since human colonisation was relatively late in world human history meaning that assemblage accumulation should show functional site types like those identified in the ethnographic record. To test this, SHE (Richness, Heterogeneity, Evenness) diversity analysis is used to examine 18 artefact and ten faunal assemblages dated pre‐1500 CE from a variety of Aotearoa locations. Results suggest artefact and faunal diversity measures perform poorly when employed to differentiate functional site types, suggesting that the null hypothesis of assemblage size dependency cannot be rejected. This result allows for comment on the appropriateness of ethnographically derived functional site types for the study of the archaeological record even when this record accumulated over short time periods.

Published: March 2022

AbstractAutism spectrum disorder (ASD) is characterized by social cognition deficits, including difficulties inferring the intentions of others. Although deficits in attribution of intentions (AI) have been consistently replicated in ASD, their exact nature remains unexplored. Here we registered the electrophysiological correlates of a nonverbal social cognition task to investigate AI in autistic adults. Twenty‐one male autistic adults and 30 male neurotypical volunteers performed a comic strips task depicting either intentional action (AI) or physical causality with or without human characters, while their electroencephalographic signal was recorded. Compared to neurotypical volunteers, autistic participants were significantly less accurate in correctly identifying congruence in the AI condition, but not in the physical causality conditions. In the AI condition a bilateral posterior positive event‐related potential (ERP) occurred 200–400 ms post‐stimulus (the ERP intention effect) in both groups. This waveform comprised a P200 and a P300 component, with the P200 component being larger for the AI condition in neurotypical volunteers but not in autistic individuals, who also showed a longer latency for this waveform. Group differences in amplitude of the ERP intention effect only became evident when we compared autistic participants to a subgroup of similarly performing neurotypical participants, suggesting that the atypical ERP waveform in ASD is an effect of group, rather than a marker of low‐task performance. Together, these results suggest that the lower accuracy of the ASD group in the AI task may result from impaired early attentional processing and contextual integration of socially relevant cues.Lay SummaryTo understand why autistic people have difficulties in inferring others' intentions, we asked participants to judge the congruence of the endings of comic strips depicting either intentional actions (e.g., fetching a chair to reach for something) or situations solely following physical rules (e.g., an apple falling on someone's head), while their electrical brain activity was recorded. Autistic individuals had more difficulties in inferring intentions than neurotypical controls, which may reflect impaired attention and contextual integration of social cues.

Published: March 2022

AbstractExcellent fast‐charging performance is a key requirement for lithium‐ion batteries intended for automotive applications. Rational particle design for active materials within electrodes represents a strategic approach to minimize kinetic limitations – especially for the anode, where the lithium intercalation rate affects the overall cell charging capacity at elevated current densities. Typically, for practical applications, natural graphite flakes are shaped into rounded particles via a mechanical spheroidization process. In this work, we show that both surface and bulk particle properties correlate strongly with the applied spheroidization conditions, and directly affect the electrochemical performance, particularly in terms of lithium‐intercalation rate. We demonstrate that graphite particles with a surface rich in prismatic planes, structural defects, and oxygen‐rich groups are favorable for fast lithium uptake. The influence of the graphite particle characteristics on the lithium intercalation rate plays a key role at the electrode and cell level, affecting the overall cell performance. We provide new insights into particle optimization during spheroidization as an effective strategy for developing fast‐charging lithium‐ion batteries.

AbstractBackgroundRecently, immunotherapy has been used to treat metastatic triple‐negative breast cancer (mTNBC). Basic research has indicated a relation between tumor heterogeneity and the immune response. Tumor heterogeneity derived from 18F‐FDG PET/CT is a potential predictor of chemotherapy results; however, few studies have focused on immunotherapy. This study aims to develop a convenient and efficient measurement of tumor heterogeneity for the prediction of immunotherapy in mTNBC patients.MethodsWe enrolled mTNBC patients who received immunotherapy (PD‐1/PD‐L1 antibody) plus chemotherapy as first‐line treatment and underwent 18F‐FDG PET/CT scans before treatment. We defined a novel index representing tumor heterogeneity calculated from the standard uptake value (SUV) as IATH and IETH. Optimal cutoffs were determined using time‐dependent receiver operator characteristics (ROC) analysis.ResultsA total of 32 patients were enrolled and analyzed in this trial. A significantly longer median PFS was observed in the low SUVmax group than in the high SUVmax group (9.4 vs. 5.8 months, HR = 0.3, 95% CI 0.1–0.9, p = 0.025). The median PFS of low‐IATH patients was significantly longer than that of high‐IATH patients (HR = 0.3, 95% CI 0.1–0.8, p = 0.022). Similarly, patients with low IETH had significantly longer PFS than patients with high IETH (9.4 vs. 4.9 months, HR = 0.3, 95% CI 0.1–0.7, p = 0.01). Multivariate analysis demonstrated IETH as an independent predictor of PFS.ConclusionsThis study proposed a novel method to assess intratumor and intertumor heterogeneity among metastatic breast cancer patients and determined that baseline IETH derived from 18F‐FDG PET/CT could represent a simple and promising predictor for first‐line immunotherapy among mTNBC patients.

AbstractBackgroundDesmoid tumors are rare neoplasms that are locally invasive. However, optimal treatment strategies for recurrent desmoid tumors remain controversial. High‐intensity focused ultrasound (HIFU) has been reported as a noninvasive modality for treating recurrent desmoid tumors. However, its efficacy against massive desmoid tumors or those with complex anatomies remains unclear.MethodsWe developed a new therapeutic strategy called low‐power cumulative HIFU and applied it to treat recurrent desmoid tumors.ResultsWe retrospectively collected data from 91 patients with recurrent desmoid tumors who underwent low‐power cumulative HIFU treatment after surgical treatment failure. The mean ablation proportion of the HIFU treatment was 69.5%, and the objective response rate was 47.3%. The 5‐year estimated progression‐free survival rate for these patients was 69.3%.ConclusionLow‐power cumulative HIFU treatment could achieve significant efficacy and long‐term control of recurrent desmoid tumors.

Published: March 2022

AbstractTerpenyl acetate, which is used for the production of flavors and fragrances, is industrially prepared from turpentine oil in a two‐step process including hydration and catalytic esterification. Such processes have several shortcomings like too‐large amounts of catalysts, non‐recyclability of catalysts, long reaction times, and serious environmental pollution. Here, a direct one‐step synthesis of terpenyl acetate from a feed mixture of turpentine oil and acetic acid with fluoroantimonic acid as superacid catalyst is described. Only 0.2 mol % of catalyst is necessary for up to 96 % conversion of starting material at room temperature. The desired product was obtained with a selectivity of up to 60 %. Thus, a clean and environmentally friendly strategy for synthesizing α‐terpenyl acetate is provided.
Different Topologies of Hg(II)‐Bispidine 1D Coordination Polymers: Dynamic Behavior in Solvent Adsorption and Exchange Processes
Authors: Lippi Martina , Murelli Andrea , Rossi Patrizia , Paoli Paola , Cametti Massimo 
Published: March 2022

AbstractOne‐dimensional (1D) coordination polymers (CPs) featuring three different topologies, comprising zig‐zag, ribbon‐like and poly‐[n]‐catenane structures, were obtained by reaction of Hg(II) ions with a novel bispidine ligand L3, and structurally characterized by SC‐ and P‐XRD methods. The CPs obtained in the form of microcrystalline powders were tested for their ability to undergo solvent adsorption and exchange by P‐XRD and 1H NMR spectroscopy. The extent of their dynamic behavior was then correlated to their structural features, highlighting the role of interchain interactions established among their constituting linear arrays. Zig‐zag CPs proved to be resilient to external chemical stimuli, while they differently respond to thermal treatments, depending on the solvent originally included within the CP. In the case of polycatenated structures, we observed transformations where the original topology was maintained upon guest exchange, but also cases where it changed to zig‐zag, even under solid/vapor conditions (i. e., no complete dissolution of the CP). Given the presence of linear interconnected 1D channels, 3 ⋅ ClBz‐polycatenanePwd is also able to trap volatile guests such as n‐hexane when exposed to its vapors.

Published: March 2022

AbstractSo far, no complete reaction mechanism has been proposed for high temperature chlorination and pyrolysis of methane. Various mechanisms for the description of this reaction pathway are combined and compared in this paper. This adaptation shows that the gas phase pyrolysis of methane and methyl chloride can be combined with surface reactions via nucleation from the gas phase or on the reactor wall to reproduce the product spectrum. In addition, kinetic parameters for a global simplified one‐step mechanism focused on the formation of carbon are fitted to available experimental data.

Authors: Cavallini Massimiliano , Gentili Denis 
Published: March 2022

AbstractStructural defects, such as heteroatoms or atomic vacancies, are always present in materials and significantly affect their physical properties, in both positive or unwanted ways. Interestingly, defects generate an impressive range of functionalities in many materials, such as catalysis, electrical and thermal conductivity tuning, thermoelectricity, enhanced ion storage, magnetism, and others. These properties enable the use of defective materials in a great variety of technological applications. Here we review the principal properties generated by atomic vacancies in 2D compounds and thin films of transition metal dichalcogenides and the most consolidated methods for their formation and engineering. Eventually, we critically analysed the most important advantages, the limits and the current open challenges.

AbstractTwo gas‐puffs are used near limiters in the FT‐2 tokamak for the purpose of hydrogen refuelling during plasma discharges. This creates toroidal and poloidal asymmetry in particle sources near limiters which has to be considered in modelling. Here, the effect of toroidal asymmetry is simulated using the gyrokinetic code ELMFIRE. Two slightly different toroidal particle sources are used in simulations, and their results are compared with each other, and with experimental measurements to understand the impact of toroidal particle sources on Scrape‐off Layer (SOL) physics.

Published: March 2022

SummaryWith the improvement of industrial informatization, various industrial control system network protocols have also been widely used. The reliability of these protocols will directly affect the safety of industrial control systems. As an effective method that can automatically analyze system reliability, model checking has been widely used in the verification of various safety‐critical systems. In this paper, we propose a modeling design method for industrial control network protocol based on time semantic reconstruction of time state transition matrix (TSTM). In addition, we provide a TSTM model checking method based on linear temporal logic (LTL). In order to effectively alleviate the state space explosion, the method adopts bounded model checking (BMC) technology. Furthermore, we implement a TSTM model verification tool called ICPV. Finally, we apply the above method to the modeling and verification of the industrial control network protocol Powerlink and through a comparison experiment with UPPAAL to illustrate the effectiveness of the method proposed in this paper.
