Published: August 2022

AbstractThe free‐standing cobalt phosphides‐based composite nanofiber mats with different compositions (CoyP/C, CoxP/Co3(PO4)2/C, where 2>x>y>1) were synthesized by electrospinning with heat treatments and applied as multi‐functional interlayers for lithium‐sulfur batteries. The polysulfide confining ability of the interlayers was evaluated by a static polysulfide adsorption test and an electrochemical conversion test using symmetric cells. The CoxP/Co3(PO4)2/C exhibited better catalytic performance for converting polysulfides, owing to the combination of CoxP with Co3(PO4)2 and P‐doped carbon. As a result, the lithium‐sulfur cell with this interlayer delivered a high initial discharge capacity of 1483 mAh g−1 at 0.1 C, retaining 705 mAh g−1 after 200 cycles at 0.5 C with 100 % Coulombic efficiency. The polysulfide trapping by the interlayer was further elucidated from the results of its ex situ characterizations after discharge and charge processes at different cycles in lithium‐sulfur cells.
Effects of Ligands on Synthesis and Surface‐Engineering of Noble Metal Nanocrystals for Electrocatalysis
Authors: Liu Moxuan , Liu Kai , Gao Chuanbo 
Published: August 2022

AbstractNoble metal nanocrystals are a family of important catalysts for a broad range of processes (especially electrocatalytic ones), which are usually obtained as a hybrid each containing a metallic core and a ligand shell. It is well recognized that the ligand plays a critical role in regulating the crystal growth into different shapes and maintaining the colloidal stability of the nanocrystals. Recently, more effects of the ligand were revealed in controlling both the synthesis and the surface property of noble metal nanocrystals, which could be maneuvered to achieve distinctive catalytic properties. In this review, we present a summary of the roles of the ligand based on typical results from the literature. The review begins with a discussion on the roles of the ligand in the controlled synthesis of noble metal nanocrystals, including the shape control, the reduction potential control for suppressing self‐nucleation and galvanic replacement reaction, and the electroless plating effect for noble metal/non‐noble metal co‐reduction. The following section includes a discussion of the effects of the ligand on the surface property of noble metal nanocrystals, including the ensemble size engineering, the ligand‐metal electron transfer, and the local microenvironment construction, toward designable electrocatalytic properties. At the end, we provide our perspectives on the future research of ligand engineering as an advanced technique for tailoring electrocatalytic properties of noble metal nanocrystals.

AbstractBackgroundMost wireless localization methods utilize only one means of detection for the surgeon, sufficient to localize a single small breast lesion for excision. Complex cases requiring bracketing of a larger lesion or localization of two or more close lesions can superimpose the signal from separate “seeds” with such methods. The lack of discernment between the localization “seeds” can disorient the surgeon, risking a missed lesion on excision and longer operative times. with the use of neoadjuvant chemotherapy prior to breast surgery, the necessity of localizing both a breast lesion and an axillary lymph node previously biopsied is becoming frequent.CaseA 44 year‐old woman underwent neoadjuvant chmotherapy for a breast cancer the did not express estrogen receptor, progesterone receptor, or HER2 receptor. In establishing the extent of disease, a suspicious ipsilateral lymph node was biopsied and found to contain metastatic disease. She had an excellent response to the chemotherapy, with decreased size of the primary tumor and the previously biopsied lymph node. The patient desired breast conservation. The primary tumor and associated calcifications were bracketed using two different Smartclips™, with a third localizing the lymph node biopsied.ConclusionThis report illustrates how the use of three SmartClips™, within the EnVisioTM system, allowed for separate tracking of each “seed” throughout a complex surgery in a patient following neoadjuvant chemotherapy. This resulted in successful resection of both the tumor and the tagged lymph node.

Published: August 2022

AbstractThe positions of nucleosomes along genomic DNA play a role in defining patterns of gene expression and chromatin organization. Determination of nucleosome positions in vivo and in vitro, as revealed by the locations of histones on DNA, has provided insight into mechanisms of nucleosome sliding, spacing, assembly, and disassembly. Here, we describe methods for the in vitro determination of histone‐DNA contacts at base‐pair (bp) resolution. The protocol involves the labeling of histones with ortho‐phenanthroline (OP), site‐specific cleavage of nucleosomal DNA, and processing and analysis of the resulting DNA fragments. This methodology provides an efficient and high‐resolution means for studying kinetics and behavior of enzymes that alter nucleosome structure and/or positioning, and can be used to identify preferred distributions of nucleosomes on natural DNA sequences. © 2022 Wiley Periodicals LLC.Basic Protocol 1: Cysteine‐specific chemical modification of folded histones with ortho‐phenanthroline (OP)Basic Protocol 2: Nucleosome sliding assay adapted for OP mapping of histone‐DNA contactsBasic Protocol 3: OP‐mediated cleavage, processing, and analysis of DNA fragments using a sequencing gelSupport Protocol 1: Preparation of dideoxy sequencing laddersSupport Protocol 2: Preparation and running of a denaturing DNA sequencing gel

AbstractIn 2019 und 2020 wurde die Balkanregion von zwei Erdbeben der Stärke MW = 6,4 heimgesucht. Am 26. November 2019 erschütterte ein Erdbeben den Nordwesten Albaniens. Es war das stärkste Erdbeben seit mehr als 40 Jahren. Städte wie Thumanë, Tirana und Durrës erlitten Schäden, wobei Durrës mit mehreren eingestürzten Gebäuden am stärksten betroffen war. Die Region Sisak‐Moslavina in Kroatien, etwa 50 km südlich von Zagreb, wurde am 29. Dezember 2020 erschüttert. Auch hier war es das stärkste Erdbeben seit dem Pokupsko‐Erdbeben vom 8. Oktober 1909 und das größte Erdbeben in der Region seit 140 Jahren. Es verursachte umfangreiche Schäden in den Städten Petrinja, Glina und Sisak sowie in zahlreichen benachbarten Kleinstädten und kleinen Siedlungen der Region. Die Schüttereffekte und Gebäudeschäden beider Erdbeben konnten im Rahmen von Feldeinsätzen untersucht und dokumentiert werden. In Durrës (Albanien) verursachte das Erdbeben erhebliche Schäden an Stahlbetonskelettbauten mit Ausfachungswänden. Schäden infolge des Erdbebens in Kroatien konzentrieren sich hingegen auf ältere und moderne Gebäude aus unbewehrtem Mauerwerk. Der Beitrag gibt einen Überblick über die erdbebeninduzierten Schäden in verschiedenen Gebäudetypen und deren Variationen. Die Ursachen der Schäden sowie die Konsequenzen für die schnelle Reaktion auf ein Erdbeben werden in engem Zusammenhang mit der Normung in moderat erdbebengefährdeten Gebieten in Europa diskutiert.

AbstractAufbauend auf den Ergebnissen aus dem Projekt „Feuchteeinträge in die Außenwandkonstruktion von Untergeschossen aufgrund von Kletterpflanzen wurden im Folgeprojekt detaillierte Untersuchungen zur Feuchtigkeit in Ziegelmauerwerk im Zusammenhang mit Kletterpflanzen durchgeführt. Vier Prüfstande, welche eine erdberührte Kellerwand aus Ziegel simulieren sollten, wurden konstruiert. Um Auswirkungen der Begrünung zu erfassen, wurde die Feuchtigkeit im Erdreich (Substrat) und im Ziegelmauerwerk kontinuierlich gemessen. Um Unterschiede zwischen verschiedenen Pflanzen untersuchen zu können, wurden drei der Prüfstände mit verschiedenen Kletterpflanzen bepflanzt und der vierte Prüfstand als Referenz ohne Bepflanzung verwendet. Bei der Auswertung wurde die Feuchtigkeit im Substrat und des Ziegelmauerwerks verglichen. Die Kletterpflanzen haben grundsätzlich für eine geringere Feuchtigkeit in Substrat und Mauerwerk gesorgt, gleichzeitig konnte kein direkter Zusammenhang zwischen den gemessenen Parametern festgestellt werden. Bei im Vergleich höherer Feuchtigkeit im Substrat liegt nicht zwangsläufig höhere Feuchtigkeit im Mauerwerk vor. Die vorgefundene Feuchtigkeit im Mauerwerk wurde anschließend in Anlehnung an ÖNORM B 3355 bewertet. Zusätzlich wurde für das verwendete Substrat und die verwendeten Ziegel die Saugspannungskurve mithilfe von Drucktopf‐Extraktoren bestimmt und ausgewertet.
Life‐history traits and temporal patterns in the incidence of coastal fishes experiencing tropicalization

Published: August 2022

AbstractClimate change is causing shifts in the geographic distributions of coastal fish species toward higher latitudes. However, local fish communities found in higher latitudes today are not simply those found in lower latitudes in the past because the sensitivity of species to various environmental conditions is different. Responses of fish to environmental conditions differ depending on their life‐history traits such as the maximum population growth rate, age of maturity, and generation time because these traits are constrained by environmental conditions. Here, we investigate associations among temporal patterns in presence–absence (incidence) data, life‐history traits of species, and environmental conditions to elucidate the potential mechanisms behind the effects of climate change on coastal fish communities. In this study, fish monitoring data collected semi‐monthly between 1982 and 2019 from eight major bays in the northwestern Gulf of Mexico were analyzed with generalized additive models. Smooth patterns over seasons and years in the incidence data of 77 species were estimated, and the data were associated with environmental variables. Further, these temporal patterns were associated with the life‐history traits of species. The results show that species that are more common in the summer months (non‐winter spawners) tend to exhibit an increasing trend and that species common during the spring (winter spawners) tend to exhibit a decreasing trend, suggesting the importance of summer conditions in driving tropicalization. Salinity had significant effects on species in general, and longer‐lived species tended to be affected by temperature. These results suggest seasonal differences in the effects of environmental conditions and variation in sensitivity to environmental conditions among different life‐history strategies. These findings represent major steps toward understanding the mechanisms behind the tropicalization of estuarine communities.
Extinction dynamics: The interplay of species traits and the spatial scales of metapopulation declines
Authors: Walker Emma J. , Gilbert Benjamin 
Published: August 2022

AbstractGlobal changes can lead to species declines and extinctions through their impacts on species habitats at two distinct spatial scales: habitat destruction, in which individual habitat patches are destroyed by land‐use change or natural disasters, and habitat degradation, in which larger scale changes, such as nitrogen deposition or climate change, lower mean population abundances across landscapes. We developed a theory showing that, even when these two forms of global change have an identical impact on a species' total amount of habitat, they have qualitatively different consequences for species dynamics and extinction. Using metapopulation theory and simulations, we found distinct impacts of these global changes characterized through several responses: the rate at which populations are lost from the remaining patches, extinction thresholds, and the duration of extinction debts. Habitat degradation causes a faster decline in species populations when habitat reduction is low, making it particularly detrimental for rare species. Habitat destruction has smaller impacts for low habitat reduction, but shows clear thresholds beyond which it surpasses degradation's negative impact; the location and steepness of the threshold depends on species dispersal, with poor dispersers having steeper thresholds. These results highlight the challenge of using population monitoring to assess the consequences of global changes and predict consequences of further change: extinction trajectories cannot be predicted due to thresholds (habitat destruction) and lagged dynamics that lead to extinction debts (habitat degradation). Our research clarifies why the impacts of one type of global change may poorly predict the impacts of the other and suggests general rules for predicting the long‐term impacts of global changes based on species traits.

Published: August 2022

AbstractMacroinvertebrates serve as key indicators in ecological assessments of aquatic ecosystems, where the composition and richness of their communities are indicative of environmental and anthropogenic change. Established monitoring of macroinvertebrates is expensive and time‐consuming, and relies on expert taxonomic knowledge. In contrast, biomonitoring based on molecular tools can support faster characterization of aquatic communities but needs validation for the target taxonomic groups and the study region. Here, we used data from a biomonitoring program covering a large biogeographic gradient to compare the routine kick‐net method with eDNA metabarcoding. We used two primer pairs targeting COI, one targeting a broad metazoan spectrum (mICOIintF/jgHCO2198) and another more recently developed primer pair optimized for the detection of freshwater invertebrates (fwhF2/EPTDr2n). We used the data of the macroinvertebrate monitoring with a focus on the orders of Ephemeroptera, Plecoptera, and Trichoptera across 92 rivers in Switzerland, covering four continental drainage basins and an elevational range from 198 to 1650 m a.s.l. Across all sample sites, the kick‐net detected more distinct taxa than either of the metabarcoding approaches. At a site level, however, both primer pairs detected on average more species. Comparing both primer pairs, the fwhF2/EPTDr2n primer pair captured more species assigned to the indicator groups Ephemeroptera, Plecoptera, and Trichoptera, and showed a significantly larger overlap with the kick‐net method. However, the community composition still varied significantly among the different metabarcoding approaches. Fewer Trichoptera species were recovered by eDNA, whereas the fwhF2/EPTDr2n primer pair detected more Plecopterans than the other two approaches. This study highlights the importance of the optimization and validation of novel molecular approaches under consideration of the target organismal group and the study area.

Published: August 2022

AbstractGlycal amides were prepared for the first time by reacting 2‐iodo‐D‐glycals with L‐amino acid esters via a Pd‐catalyzed carbonylative cross‐coupling reaction, by using Mo(CO)6 as the carbon monoxide source. Glycal amides were synthesized in moderate to good yields under our optimized conditions. In addition, the acetyl groups of the glucal amides could be readily removed to obtain the corresponding trihydroxy derivatives in good yields.

AbstractAttempts to synthesize fluorosulfonyl‐substituted pyrazolines by Huisgen reactions (1,3‐dipolar cycloadditions) of dimethyl diazomalonate with ethenesulfonyl fluoride led to the formation of dimethyl (2R*,3S*,4R*)‐2‐(1,3‐dimethoxy‐1,3‐dioxopropan‐2‐yl)‐3‐(fluorosulfonyl)‐4‐((fluorosulfonyl)methyl)cyclobutane‐1,1‐dicarboxylate, a highly substituted cyclobutane derivative, which was characterized by NMR spectroscopy and single crystal X‐ray crystallography. The mechanism of its formation was elucidated by carrying out the reaction at different temperatures and workup conditions. It is shown that an initial 1,3‐dipolar cycloaddition yields a pyrazoline which extrudes nitrogen with formation of 1‐fluorosulfonyl‐2,2‐bis(methoxycarbonyl)cyclopropane and dimethyl 2‐(2‐(fluorosulfonyl)ethylidene)malonate, the latter of which dimerized during chromatography on silica gel with formation of the isolated cyclobutane.

AbstractThe accuracy of lithium‐ion battery state estimation is critical to the safety of unmanned aerial vehicles (UAVs). In this paper, aiming at the high‐fidelity modeling of the UAV lithium‐ion battery, a splice‐electrochemical polarization model (S‐EPM) for UAV lithium‐ion battery is constructed by combining the traditional electrochemical model with the equivalent circuit model, which greatly improved the accuracy of the battery modeling. In addition, a novel prior generalized inverse least‐squares algorithm is proposed. Also, based on this algorithm, the full‐parameter identification and multicondition error analysis of the S‐EPM are realized based on this algorithm. Finally, a targeted complex discharge rate test and a full‐function charge–discharge test were designed to further verify the applicability of the S‐EPM to complex conditions. The experimental results show that the voltage error of the model under each working condition is 5.50 and 3.0 mV, and the maximum percentage error ratio is 0.20% and 0.07%. This experiment can provide a theoretical basis for the combination of the electrochemical model and equivalent circuit model and the accurate estimation of internal state variables of lithium‐ion batteries.
Marine species introduction via reproduction and its response to ship transit routes

Published: August 2022

AbstractThe introduction of nonindigenous species (NIS) threatens global ecosystems and results primarily from human transportation and trade activities. Although some NIS can disperse immediately upon arrival (for example, mobile species), actual inoculation for other (sessile) species can require a reproductive event to produce propagules that disperse and establish. NIS reproductive potential, however, can vary with environmental conditions experienced during transit and upon arrival that differ substantially by route. We propose that variation in reproductive responses, both across species and transit routes, is a critical but overlooked driver of species invasions. We illustrate these concepts using vessel biofouling organisms, which are exposed to vastly different conditions during transport across the world’s oceans. Current knowledge gaps prevent precise predictions of the potential for species to be introduced via reproduction. Integrating reproductive potential into management strategies is key to limiting NIS spread, particularly as climate change and novel events continue to alter global transportation networks.Front Ecol Environ 2022;
The impact of a national formulary expansion on diabetics
Authors: McNamara Cici , Serna Natalia 
Published: August 2022

AbstractThis paper estimates the causal effect of the expansion of Colombia's national prescription drug formulary to include five new types of insulin on the healthcare utilization and costs of type I diabetics and explores the mechanisms through which outpatient cost reductions are realized. We find that expanded coverage generates an increase in the cost of insulin for type I diabetics equal to 17% of their baseline healthcare costs. At the same time, their annual outpatient care utilization falls by 1.9 claims. We devise tests to explore the relative importance of two mechanisms by which the expansion may have lowered type I diabetics' non‐drug healthcare utilization: spillovers from drug to non‐drug spending and rationing of care. We find no evidence that the formulary expansion reduces the rate of complications from diabetes and find substantial declines in non‐drug costs even among the subset of diabetics with no scope for spillovers. We find large reductions in the utilization of discretionary care including diagnostic tests, but no such declines for the use of essential drugs, suggesting that rationing of care is the primary driver of observed cost savings.
