Published: May 2023

AbstractCompounds with 1‐aminoindane motif exhibit vital biological activities in the central nervous system. Therefore, it is very important to synthesize new compounds with this moiety and to obtain them in high enantiopurity. In this study, novel substituted 1‐aminoindane derivatives were synthesized, and their asymmetric resolutions were carried out. Accordingly, the reduction of 1‐indanones with NaBH4, conversion of alcohols to azides via an alternative Mitsunobu reaction followed by reduction of azides afforded (±)‐1‐aminoindane hydrochloride or hydrobromide salts. Amine salts were converted into their free amines by using excess amount of Et3N and then in situ occurred free (±)‐amines were reacted with (R)‐O‐acetylmandeloyl chloride to give diastereomeric mixtures. The crystallization of the diastereomeric mixtures followed by hydrolysis yielded the corresponding asymmetric amines with high enantio‐purity.
A Facile Dual‐Emission Ratiometric Carbon‐Dot Fluorescent Probe and Its Application in Portable Chemical Sensors and Water Quality Analysis
Authors: Wu Weijun , Mao Jie , Lu Yifei , Wang Sui 
Published: May 2023

AbstractBased on the dual signal of double‐emitting carbon quantum dots (G‐CDs), a ratiometric fluorescence sensor is established to realize the analysis and detection of Fe3+in real samples. When the excitation wavelength is 360 nm and 480 nm, the double emission fluorescence peaks are located at the wavelengths of 477 nm and 523 nm. The former is the fluorescence response signal, and the latter is the fluorescence background signal. The semi‐quantitative analysis of Fe3+was achieved based on the linear relationship between the ratio F477/F523of the two signals and the Fe3+concentration. The linear range of this method is 0.015–120 μM, and the limit of detection (LOD, S/N=3) is 5 nM. Meanwhile, the naked‐eye visual detection of Fe3+can be realized according to the fluorescence color of the probe. The probe exhibits excellent anti‐interference, selectivity and repeatability, and this method can be applied to the detection of Fe3+in actual samples.

AbstractCrystal packing and chromophore communication are key parameters for the performance and functionality of many applications related to light‐energy harvesting and conversion. However, obtaining crystals of flexible and very soluble structures is troublesome. Nevertheless, a crystal structure of a highly flexible perylene‐3,4 : 9,10‐tetracarboxylic acid bisimide (PBI) cyclophane was obtained and analysed to compare the chromophore arrangement in the solid state with theconfiguration in solution as well as with calculated structures. The crystal structure exhibits an intra‐ and intermolecular slip‐stack arrangement of the heterochiral PBI units, forming a unique one‐dimensional π‐stacking supramolecular polymer‐like structure. These findings emphasize that the unique solid‐state arrangement of the chromophores cannot be easily predicted by elaborate studies in solution or by theoretical calculations. Furthermore, it features the importance of controlling the crystal packing to enable specific applications based on multiexciton generation processes where the spatial dependence and relative orientation of the chromophores are decisive parameters.
In Silico Activation of CO2, NO2, and SO2 with Light Atom Molecules and Stepwise Conversion of CO2 into Methanol and Water
Authors: Mebs Stefan , Beckmann Jens 
Published: May 2023

AbstractCO2, NO2, and SO2 can be activated in silico with tailor‐made light atom tripodal ligand systems carrying particular numbers of Lewis acidic and basic sites in specific relative orientations. In the calculated EO2‐adducts (E=C, N, S), considerable E−O bond elongations of 0.1–0.3 Å, decreasing the E=O double bond character, and O−E−O angle alterations, approaching tetrahedral geometry, activate the donor acceptor complexes towards reduction with BH4−. The lone pairs of the P atoms thereby serve as donors towards the central element, C, N, or S, whereas the electron deficient B atoms serve as acceptors. The charge redistribution within the EO2 complex was monitored by a variety of DFT‐derived real‐space bonding indicators (RSBIs) including bond topologies, non‐covalent contact patches, and electron pair basins. For one CO2‐complex, the reduction towards methanol and water was conducted via stepwise addition of H− and H+. The most critical steps are the initial CO2 uptake due to potential quenching of the ligand systems in their active state, increasing the kinetic barrier, and the release of methanol and water from the ligand system due to potential ligand poisoning. Unbeneficial side reactions in the stepwise reduction and protonation have to be considered.

AbstractViologens‐based electrochromic (EC) devices with multiple color changes, rapid response time, and simple all‐in‐one architecture have aroused much attention, yet suffer from poor redox stability caused by the irreversible aggregation of free radical viologens. Herein, the semi‐interpenetrating dual‐polymer network (DPN) organogels are introduced to improve the cycling stability of viologens‐based EC devices. The primary cross‐linked poly(ionic liquid)s (PILs) covalently anchored with viologens can suppress irreversible face‐to‐face contact between radical viologens. The secondary poly(vinylidenefluoride‐co‐hexafluoropropylene) (PVDF‐HFP) chains with strong polar groups of ‐F can not only synergistically confine the viologens by the strong electrostatic effect, but also improve the mechanical performance of the organogels. Consequently, the DPN organogels show excellent cycling stability (87.5% retention after 10 000 cycles) and mechanical flexibility (strength of 3.67 MPa and elongation of 280%). Three types of alkenyl viologens are designed to obtain blue, green, and magenta colors, demonstrating the universality of the DPN strategy. Large‐area EC devices (20 × 30 cm) and EC fibers based on organogels are assembled to demonstrate promising applications in green and energy‐saving buildings and wearable electronics.

AbstractDistributed in Central Asia, Metastachydium (Lamiaceae) is a poorly understood and rare monotypic genus, with few collections known. The systematic position of this enigmatic genus within Lamiaceae has remained unresolved due to its poor representation in herbaria and coincident lack of available materials for molecular phylogenetic analysis. Facilitated by some recent collections, we performed Bayesian inference and maximum likelihood analyses, using an 80‐protein‐coding plastid‐gene dataset of Lamioideae, to infer the systematic placement of Metastachydium at the tribal level within Lamioideae. In addition, we used an 8‐plastid‐DNA‐region dataset as well as the nuclear ribosomal internal transcribed spacer to determine the phylogenetic affinities of Metastachydium. All phylogenetic analyses agree that Metastachydium is a member of Phlomideae and deeply nested within the genus Phlomoides, suggesting the need to expand the latter to include Metastachydium. Hence, a new combination, Phlomoides sagittata comb. nov., is proposed, and we present the first available photographs and an amended morphological description of P. sagittata. In addition, the infrageneric circumscription of Phlomoides is not supported, as most sections and subsections are not monophyletic. Hybridization and incomplete lineage sorting, following rapid diversification within Phlomoides, seem to be the source of incongruence between the nuclear and plastid tree topologies.

AbstractArgumentation is fundamental to science education, both as a prominent feature of scientific reasoning and as an effective mode of learning—a perspective reflected in contemporary frameworks and standards. The successful implementation of argumentation in school science, however, requires a paradigm shift in science assessment from the measurement of knowledge and understanding to the measurement of performance and knowledge in use. Performance tasks requiring argumentation must capture the many ways students can construct and evaluate arguments in science, yet such tasks are both expensive and resource‐intensive to score. In this study we explore how machine learning text classification techniques can be applied to develop efficient, valid, and accurate constructed‐response measures of students' competency with written scientific argumentation that are aligned with a validated argumentation learning progression. Data come from 933 middle school students in the San Francisco Bay Area and are based on three sets of argumentation items in three different science contexts. The findings demonstrate that we have been able to develop computer scoring models that can achieve substantial to almost perfect agreement between human‐assigned and computer‐predicted scores. Model performance was slightly weaker for harder items targeting higher levels of the learning progression, largely due to the linguistic complexity of these responses and the sparsity of higher‐level responses in the training data set. Comparing the efficacy of different scoring approaches revealed that breaking down students' arguments into multiple components (e.g., the presence of an accurate claim or providing sufficient evidence), developing computer models for each component, and combining scores from these analytic components into a holistic score produced better results than holistic scoring approaches. However, this analytical approach was found to be differentially biased when scoring responses from English learners (EL) students as compared to responses from non‐EL students on some items. Differences in the severity between human and computer scores for EL between these approaches are explored, and potential sources of bias in automated scoring are discussed.
A global perspective on combatingShanzhaiproducts: Cross‐cultural solutions

AbstractTo compete on the world market, companies from emerging economies often adapt their innovations to satisfy unique cultural needs. They do so, in part, by copying the products of their western counterparts with a degree of modification. This approach is referred to asShanzhai,which is a Chinese neologism meaning “copycat.” In this article, we discuss theShanzhaiphenomenon and explainShanzhai'sdevelopment stages and threats to original brands across the globe. Then, we examine how cultural factors (i.e., power distance belief, face consciousness, and analytic vs. holistic‐thinking style) influence consumers’ perception towardsShanzhaiproducts. We further suggest that original manufacturers should adopt selected strategies to combatShanzhaithreats vis‐à‐vis three cultural drivers. One driver entails launching full product lines and developing new distribution channels in high power distance belief cultures but promoting brand originality in low power distance belief cultures. A second alternative involves embracing a sustainable and green brand image in low face‐sensitive cultures but strengthening brand logo impacts and enhancing intangible brand benefits—such as social value (e.g., brand user profile, prestige)—in high face‐sensitive cultures. The third entails communicating integrated product values in holistic‐thinking cultures but highlighting an offering's most competitive and unique features in analytic‐thinking cultures.

AbstractGenomic selection (GS) proposed by Meuwissen et al. more than 20 years ago, is revolutionizing plant and animal breeding. Although GS has been widely accepted and applied to plant and animal breeding, there are many factors affecting its efficacy. We studied 14 real datasets to respond to the practical question of whether the accuracy of genomic prediction increases when considering genomic as compared with not using genomic. We found across traits, environments, datasets, and metrics, that the average gain in prediction accuracy when genomic information is considered was 26.31%, while only in terms of Pearson's correlation the gain was of 46.1%, while only in terms of normalized root mean squared error the gain was of 6.6%. If the quality of the makers and relatedness of the individuals increase, major gains in prediction accuracy can be obtained, but if these two factors decrease, a lower increase is possible. Finally, our findings reinforce genomic is vital for improving the prediction accuracy and, therefore, the realized genetic gain in genomic assisted plant breeding programs.

AbstractGenetic testing plays an important role in human health management and disease prevention. However, traditional genetic testing methods have been unable to fulfill the current diagnostic needs owing to several limitations, including high cost, complexity, and difficulty in performing. Smartphones have multiple inherent advantages, such as easy portability, ubiquity, fast processing speed, and excellent imaging capabilities, and have enormous potential in realizing rapid on‐site genetic testing. The present review documents the research progress of smartphone‐based optical imaging biosensors in the fields of colorimetry, fluorescence, and microscopic imaging for genetic testing. Furthermore, the review describes their potential applications in diagnostics, which range from infectious diseases to hereditary diseases and cancers. Finally, the challenges and perspectives of smartphone‐based optical imaging biosensors regarding genetic testing are discussed.
Timing of Seep Activities and Potential Driving Forces
Authors: Feng Dong 
Published: May 2023

AbstractOne of the foremost topics in seep research is the timing of seep activities and their potential driving forces. In the South China Sea, seep activities are primarily driven by gas hydrate dissociation–destabilization of gas hydrate leads to a release of methane. As decreases in pressure and increases in temperature promote gas hydrate dissociation, ocean warming and sea level lowstands are proposed to cause the dissociation of gas hydrate deposits and consequently induce methane seepage at the seafloor. Cross-slope investigations suggest that the bottom water pressure‒temperature conditions appear to have different impacts on seeps at different water depths. It is possible that seepage in the upper continental slope is more sensitive to sea level changes than that in the middle and lower continental slopes, which are more sensitive to bottom water temperature. Scientific drilling and the application of a range of geochemical and geophysical analytical approaches are proposed to advance our understanding of the temporal evolution of seep systems in the South China Sea.
Validation of a predictive model for speech discrimination after cochlear impIant provision
Authors: Hoppe Ulrich , Hast Anne , Hocke Thomas 
Published: May 2023

Abstract
Background
If sufficient speech discrimination is no longer achieved with conventional hearing systems, an audiological indication for a cochlear implant (CI) is given. However, there are no established target criteria for CI aftercare with regard to the level of speech comprehension to be achieved. The aim of this study is to validate an existing predictive model for speech comprehension after CI provision. This is applied to different patient groups.

Materials and methods
The prospective study included 124 postlingually deaf adults. The model is based on preoperative maximum monosyllabic recognition score, aided monosyllabic recognition score at 65 dBSPL, and age the time of implantation. The model was investigated with regard to prediction accuracy for monosyllabic recognition with CI after 6 months.

Results
Mean speech discrimination improved from 10% with hearing aid to 65% with CI after 6 months, with a statistically significant improvement in 93% of cases. Deterioration of aided unilateral speech discrimination was not observed. The mean prediction error was 11.5 percentage points in the cases with preoperative scores better than zero and 23.2 percentage points in all other cases.

Conclusion
Cochlear implantation should also be considered in patients with moderately severe to severe hearing loss and insufficient speech discrimination with hearing aids. The model based on preoperatively measured data for predicting speech discrimination with CI can be used in preoperative consultation and in the context of postoperative quality assurance.
Impact of genetic relatedness on reproductive behavior in Pelvicachromis pulcher, a biparental cichlid fish with mutual mate choice and ornamentation

Abstract
Inbreeding can result in inbreeding depression. Therefore, many species seek to avoid inbreeding. However, theory predicts that inbreeding can be beneficial. Accordingly, some species tolerate inbreeding or even prefer mating with close relatives. Evidence for active inbreeding, i.e., kin-mating preference was reported in the biparental African cichlid fish Pelvicachromis taeniatus. Related mating partners revealed better parental cooperation due to kin selection, a potential benefit of inbreeding. In this study, we investigated kin-mating preference in a genetically diverse, outbred F2-lab population of Pelvicachromis pulcher, a closely related species to P. taeniatus. Like P. taeniatus, this species shows mutual ornamentation and mate choice as well as intense biparental brood care. The F1 P. pulcher generation had revealed signs of inbreeding depression but no inbreeding avoidance. We studied mating behavior and aggression in trios consisting of a male P. pulcher, an unfamiliar sister, and an unfamiliar, unrelated female. Because the study focused on kin-mating patterns, female pairs were matched for body size and coloration. The results provide no evidence for inbreeding avoidance but rather suggest inbreeding preference. We also found no significant impact of inbreeding on offspring survival. The results suggest no inbreeding avoidance in P. pulcher; however, the strength of inbreeding preference and inbreeding depression seems to be variable. We discuss possible causes for this variation like context-dependent inbreeding depression. The number of eggs positively correlated with female body size and coloration. Furthermore, the female aggressiveness was positively correlated with female coloration indicating that coloration signal female dominance and quality.
Complex preference relationships between native and non-native angiosperms and foraging insect visitors in a suburban greenspace under field and laboratory conditions

Published: May 2023

Abstract The introduction and spread of non-native flora threatens native pollinators and plants. Non-native angiosperms can compete with native plants for pollinators, space, and other resources which can leave native bees without adequate nutritional or nesting resources, particularly specialist species. In the current study, we conducted flower preference experiments through field observations and controlled binary choice tests in an artificial arena to determine the impact of field vs. laboratory methods on flower preferences of native bees for native or non-native flowers within their foraging range. We conducted counts of insect pollinators foraging on the flowers of three plant species in a suburban green belt including one native (Arthropodium strictum) and two non-native (Arctotheca calendula and Taraxacum officinale) plant species. We then collected native halictid bees foraging on each of the three plant species and conducted controlled binary tests to determine their preferences for the flowers of native or non-native plant species. In the field counts, halictid bees visited the native plant significantly more than the non-native species. However, in the behavioural assays when comparing A. strictum vs. A. calendula, Lasioglossum (Chilalictus) lanarium (Family: Halictidae), bees significantly preferred the non-native species, regardless of their foraging history. When comparing A. strictum vs. T. officinale, bees only showed a preference for the non-native flower when it had been collected foraging on the flowers of that plant species immediately prior to the experiment; otherwise, they showed no flower preference. Our results highlight the influence that non-native angiosperms have on native pollinators and we discuss the complexities of the results and the possible reasons for different flower preferences under laboratory and field conditions.
