＜正＞In this paper, the derivation of two new scores from the Partial Least Squares （PLS） algorithm is outlined. These new scores provide an alternative approach for the condition monitoring of industrial processes. This alternative approach, combined with the kernel density estimation, is applied in a case study of a real industrial process.

The safety and durability of lithium-ion batteries under mechanical constraints depend significantly on electrochemical, thermal, and mechanical fields in applications. Characterizing and quantifying the multi-field coupling behaviors requires interdisciplinary efforts. Here, we design experiments under mechanical constraints and introduce an in-situ analytical framework to clarify the complex interaction mechanisms and coupling degrees among multi-physics fields. The proposed analytical framework integrates the parameterization of equivalent models, in-situ mechanical analysis, and quantitative assessment of coupling behavior. The results indicate that the significant impact of pressure on impedance at low temperatures results from the diffusion-controlled step, enhancing kinetics when external pressure, like 180 to 240 k Pa at 10 °C, is applied. The diversity in control steps for the electrochemical reaction accounts for the varying impact of pressure on battery performance across different temperatures. The thermal expansion rate suggests that the swelling force varies by less than 1.60% per unit of elevated temperature during the lithiation process. By introducing a composite metric, we quantify the coupling correlation and intensity between characteristic parameters and physical fields, uncovering the highest coupling degree in electrochemical-thermal fields. These results underscore the potential of analytical approaches in revealing the mechanisms of interaction among multi-fields, with the goal of enhancing battery performance and advancing battery management.

This paper asks how the livability of socially disadvantaged urban neighborhoods can be improved with the help of publicly funded area-based urban regeneration.It builds on the history of area-based regeneration policies in Germany aiming at upgrading and resolving urban problems at the neighborhood level.Its main argument is as follows.First,the fate of conventional physical upgrading policies focusing on the livability of deprived urban areas depends on the development environment.While successful upgrading sometimes makes inner-city neighborhoods so attractive that they run into a trend towards gentrification and displacement of the urban poor,the stabilization of less privileged areas cannot always be guaranteed.Second,alternative approaches are needed,linking limited physical upgrading with socially oriented policies,building on strategies like neighborhood management and empowerment.Third,they can make a substantial contribution to stabilizing deprived neighborhoods,thereby improving the general living conditions and the opportunities of the urban poor.However,they require at least some permanent intervention.Thus,they transcend the logic of area-based regeneration normally limited to restoring faith into the private real estate market and thereby directing inward investment into them that improves the quality of the physical environment.Fourth,they are hardly able to overcome significant negative stigmatization in cities that are severely hit by economic downturn and population decline.This is especially true when they act as arrival areas for consecutive waves of migrants,making it necessary to redefine the role of those areas in cities and accepting their high concentration of urban problems as a starting point for different area-based policies dealing with them.The key empirical background of the paper is the German system of urban development grants and an evaluation of the so-called program of“socially integrative city”.

In a recent paper published in Nature Immunology,Ding et al.provided new insights into the mechanism of how trained innate immunity could eradicate cancer.The authors demonstrated that yeast-derived whole beta-glucan particles(WGP)increased the responsiveness of lung interstitial macrophages to tumor-derived factors associated with the subsequent inhibition of tumor metastasis through enhanced cytotoxicity to cancer cells.The authors identified the metabolic sphingolipid–mitochondrial fission axis in WGP-trained macrophages as the key pathway responsible for this phenomenon and categorized it as a mechanism of trained innate immunity[1].

Under natural conditions,photosynthesis has to be adjusted to fluctuating light intensities.Leaves exposed to high light dissipate excess light energy in form of heat at photosystem II(PSII)by a process called non-photochemical quenching(NPQ).Upon fast transition from light to shade,plants lose light energy by a relatively slow relaxation from photoprotection.Combined overexpression of violaxanthin de-epoxidase(VDE),PSII subunit S(PsbS)and zeaxanthin epoxidase(ZEP)in tobacco accelerates relaxation from photoprotection,and increases photosynthetic productivity.In Arabidopsis,expression of the same three genes(VPZ)resulted in a more rapid photoprotection but growth of the transgenic plants was impaired.Here we report on VPZ expressing potato plants grown under various light regimes.Similar to tobacco and Arabidopsis,induction and relaxation of NPQ was accelerated under all growth conditions tested,but did not cause an overall increased photosynthetic rate or growth of transgenic plants.Tuber yield of VPZ expressing plants was unaltered as compared to control plants under constant light conditions and even decreased under fluctuating light conditions.Under control conditions,levels of the phytohormone abscisic acid(ABA)were found to be elevated,indicating an increased violaxanthin availability in VPZ plants.However,the increased basal ABA levels did not improve drought tolerance of VPZ transgenic potato plants under greenhouse conditions.The failure to benefit from improved photoprotection is most likely caused by a reduced radiation use efficiency under high light conditions resulting from a too strong NPQ induction.Mitigating this negative effect in the future might help to improve photosynthetic performance in VPZ expressing potato plants.

Agriculture is facing a massive increase in demand per hectare as a result of an ever-expanding population and environmental deterioration.While we have learned much about how environmental conditions and diseases impact crop yield,until recently considerably less was known concerning endogenous factors,including within-plant nutrient allocation.In this review,we discuss studies of source-sink interactions covering both fundamental research in model systems under controlled growth conditions and how the findings are being translated to crop plants in the field.In this respect we detail efforts aimed at improving and/or combining C3,C4,and CAM modes of photosynthesis,altering the chloroplastic electron transport chain,modulating photorespiration,adopting bacterial/algal carbon-concentrating mechanisms,and enhancing nitrogen-and water-use efficiencies.Moreover,we discuss how modulating TCA cycle activities and primary metabolism can result in increased rates of photosynthesis and outline the opportunities that evaluating natural variation in photosynthesis may afford.Although source,transport,and sink functions are all covered in this review,we focus on discussing source functions because the majority of research has been conducted in this field.Nevertheless,considerable recent evidence,alongside the evidence from classical studies,demonstrates that both transport and sink functions are also incredibly important determinants of yield.We thus describe recent evidence supporting this notion and suggest that future strategies for yield improvement should focus on combining improvements in each of these steps to approach yield optimization.
