AbstractTo improve electrocatalytic performances of Pt‐based catalysts toward methanol oxidation reaction (MOR) and reduce the consumption of Pt, we report a novel strategy for preparing a PtCo/NCS catalyst with bimetallic PtCo nanoparticles supported on the nitrogen‐doped carbon skeleton (NCS) derived from ulmic‐acid ‐based ZIF‐67 (UA‐ZIF‐67) template. The synthesized optimal NCS has rich mesoporous structure with a BET specific surface area of 451 m2 g−1and average pore diameterof 4.5 nm, possesses graphitic structure containing some CNTs and many graphene layers, and is doped by 8.16 at% nitrogen in the form of pyridine N and pyrrole N. In the optimum PtCo/NCS, metallic Pt and Co nanoparticles with an average size of 3.0±0.5 nm are uniformly supported on the NCS. This PtCo/NCS catalyst shows a high electrocatalytic activity and stability for MOR due to its high electrochemically active specific surface area (ECSA) value, current density, steady‐state current and current retention. The results are attributed to small highly‐dispersed PtCo nanoparticles with good synergistic effects of bimetallic active components supported on the NCS possessing CNTs and graphene layers, suitable nitrogen doping and well‐matched hierarchical pore structure.These findings will provide a new insight in designing and synthesizing high‐performance electrocatalysts.

AbstractDetrimental lithium polysulfide (LiPS) shuttle effects and sluggish electrochemical conversion kinetics in lithium‐sulfur (Li‐S) batteries severely hinder their practical application. Separator modification has been extensively investigated as an effective strategy to address above issues. Nevertheless, in the case of functional separators, how to effectively block the LiPSs from diffusion while enabling the rapid Li ion transport remains a challenge. Herein, by using an “oxidation‐etching” method, MXene membranes are presented with controllable in‐plane pores as interlayer to regulate Li ion transportation and LiPS immobilization. Porous MXene membranes with optimized pore density and size can simultaneously anchor LiPS and ensure fast Li ion diffusion. Consequently, even with pure sulfur cathode, the improved Li–S batteries deliver excellent rate performance up to 2 C with a reversible capacity of 677.6 mAh g−1 and long‐term cyclability over 500 cycles at 1 C with a low capacity decay of 0.07% per cycle. This work sheds new insights into the design of high‐performance interlayers with manipulated nanochannels and tailored surface chemistry to regulate LiPSs trapping and Li ion diffusion in Li–S batteries.
An early Eocene fossil from the British London Clay elucidates the evolutionary history of the enigmatic Archaeotrogonidae (Aves, Strisores)
Authors: Mayr Gerald 
Published: July 2021

AbstractArchaeotrogons have long been known from late Eocene and Oligocene localities in France, where limb bones are abundantly represented. The phylogenetic affinities of these birds, however, have remained elusive. Although archaeotrogons are now considered to be representatives of the Strisores, the clade including ‘caprimulgiform’ and apodiform birds, their exact position in this clade is unresolved. Here, a partial skeleton of a new species of the Archaeotrogonidae is described from the early Eocene London Clay of Walton‐on‐the‐Naze (Essex, UK). In addition, a new specimen of the archaeotrogon Hassiavis from the latest early or earliest middle Eocene of the Messel fossil site in Germany is reported, which is the best preserved skeleton of this species. Archaeodromus anglicus gen. et sp. nov. from the London Clay is the earliest archaeotrogon known to date, and the holotype shows previously unknown skeletal characteristics of archaeotrogons that bear on the phylogenetic affinities of these birds. The quadrate in particular exhibits a distinctive morphology and shows derived morphological characteristics of the Strisores. Although the primary analysis did not conclusively resolve the affinities of archaeotrogons, analyses constrained to a molecular scaffold resulted in a sister group relationship to the Caprimulgidae (nightjars). The evolutionary history of this most species‐rich group of nocturnal Strisores is virtually unknown, and recognition of archaeotrogons as archaic stem group representatives of the Caprimulgidae would fill a striking gap in the fossil record.
Detection and defense of network virus using data mining technology
Authors: Li Zhijun , Jiang Xuedong 
Published: July 2021

AbstractThe spread of network viruses has posed a serious threat to the security of the network; therefore, it is necessary to detect and defend them effectively. This paper used debugging application programming interface (API) technology to obtain the features of API calls as viruses, filtered API calls according to information entropy, and finally used the support vector machine (SVM) model for virus detection. The experimental results showed that when the number of API was 1200, the algorithm had the best virus detection performance, with an average true positive rate (TPR) of 95.2%, a false positive rate (FPR) of 3.31%, and an overall accuracy of 95.42%; compared with the C4.5 algorithm, the K‐means algorithm, and the Naive Bayes algorithm, the SVM algorithm had the best performance. The results show that the proposed method is effective in virus detection and defense and can be further promoted and applied in practice.

AbstractIntroductionThis study elicited Asian Americans and Pacific Islanders’ (AAPI) perspectives about recruitment strategies/messaging for participation in an aging, Alzheimer's disease and related dementias (ADRD), and caregiving research recruitment registry.MethodsUsing a mixed methods design, CARE (Collaborative Approach for AAPI Research and Education) conducted 14 focus groups (N = 123) with AAPI cultural groups (Asian Indian, Chinese, Filipino, Japanese, Korean, Samoan, Vietnamese) in different languages. Descriptive statistics and thematic qualitative analyses were conducted.ResultsMean age of participants was 54 years (median: 61; range 18–80), 66% were female, and 81% were foreign‐born. Themes of consideration for recruitment emerged: (1) culturally/linguistically appropriate outreach in culturally specific spaces, (2) motivations for research participation, and (3) approaches to outreach and recruitment methods. Within each of these themes, there were ethnic differences in specific strategies/approaches reflected as subthemes.DiscussionRecruitment and messaging strategies should be tailored uniquely for each targeted AAPI group, with a thorough understanding of the cultural/linguistic factors that facilitate research participation to increase AAPI participation in ADRD, aging, and caregiver‐related research.
Atresia coli in a 1‐day‐old cria
Authors: Knecht Isabella , Pinn‐Woodcock Toby , Craven Amanda , Fubini Susan 
Published: July 2021

AbstractA 1‐day‐old female alpaca cria presented to Cornell University's large animal internal medicine service for abdominal pain. On presentation, the cria appeared septic with hyperemic mucous membranes and marked abdominal distention. Abdominal ultrasound showed distended, hypomotile loops of small intestine with increased anechoic free peritoneal fluid. Abdominal radiographs with a barium enema showed gas distended proximal colon and marked segmental narrowing of the descending colon. Abdominal exploratory surgery revealed a meconium‐filled blind end in the proximal loop of the ascending colon and a collapsed, empty spiral and descending colon, consistent with a diagnosis of atresia coli. The location of this cria's atresia coli differed in location from the more commonly reported atretic spiral colon lesions seen in calves and was associated with poor surgical prognosis. This species variation is an important consideration prior to surgery and may help inform surgical decisions for those faced with similar cases in the future.

Impact
Authors: Jonker Jan , Faber Niels 
Published: July 2021

AbstractThis chapter unpacks the Impact building block. It seeks to determine the impact that your business model will have on the broader social, ecological, economic, and material environment. We think it is important to clarify the short- and long-term effects of your business model. Framing and defining this building block is often challenging. It can be defined in a general sense, but can also be focused on specific stakeholders, a raw material, or a specific context or a relevant combination of indicators. Indicators are also increasingly linked to measuring and reporting methods. We offer various methods to test the set of indicators and link them to reporting standards. Keep a keen eye on the practical feasibility, as well as the costs involved in measuring and reporting. Identifying proper and useful indicators and measuring and monitoring them are easier said than done. Whatever you do, stick to the motto Keep it Simple.
Epilogue
Authors: Jonker Jan , Faber Niels 
Published: July 2021

AbstractWe live in a time of social transition. Everywhere in society, cracks are appearing. The only answer to these developments is to organize in radically different ways, saying goodbye to the present linear economy. That is what transition is all about. The search for new forms of value creation and the triple transition necessitates different business models. In turn this implies behavioural change, which may be the biggest challenge and greatest barrier to achieving a transition to a sustainable, circular, and inclusive economy. This book deliberately does not address the issue of change and transition. That would require yet another book. But to finish off we provide an overview of the obstacles and challenges of creating fundamental change. We say goodbye by providing you with the six elements of a successful business model. The key message of this last chapter is that mainstreaming sustainable business models is by no means a given, but over time will become the new normal.
Business Model Archetypes
Authors: Jonker Jan , Faber Niels 
Published: July 2021

AbstractThe BMT provides the building blocks to develop a logic for a business model. In such a model the nature of value creation, how value creation is organized, and how transactions are taking shape are operationalized so that they meet the proposition. Practice shows that at present business models aimed at capturing multiple value creation can be divided into three major categories: (1) platform business models, (2) community-based (or collective) business models, and (3) circular business models. The three archetypes differ mainly in the way in which they create value, as well as the objective, the mechanism through which value creation takes place, and the infrastructural and technological requirements. When using the BMT, it is useful to consider at an early stage which business model archetype is dominant in the realization of the intended value proposition. Choosing a business model archetype might look straightforward, but it can be quite a tricky task.
Attending to the External Environment to Identify Potential Opportunities
Authors: Shepherd Dean A. , Patzelt Holger 
Published: July 2021

AbstractBuilding on a recent study (Shepherd et al. in Strategic Management Journal 38:626–644, 2017), this chapter highlights the importance of noticingopportunities as an initial step toward new venture creation. Unsurprisingly, there has been considerable interest in the processes of allocating attention to notice potential opportunities arising from changes in the external environment. We know a great deal about the role of top-down (i.e., based on knowledge and experience) processes of allocating attention to the environment in forming opportunity beliefs worthy of entrepreneurial action. However, in this chapter, we illustrate how bottom-up processes, whereby environmental changes capture entrepreneurs’ attention, shape opportunity identification. Building on the notion of guided attention, we detail an attention model of forming opportunity beliefs for entrepreneurial action that includes both top-down and bottom-up processes for allocating attention. This chapter explains how entrepreneurs can allocate their transient attention to identify potential opportunities from environmental changes. This chapter also describes how allocating sustained entrepreneurial attention influences belief formation about radicaland incremental opportunities requiring entrepreneurial action.

Doing und undoing gender in Interaktionen: Analyse der videogestützten Beobachtung
Authors: Vogt Franziska 
Published: July 2021

ZusammenfassungDie Interaktion zwischen Kinderbetreuenden und Kindern ist wesentliches Qualitätsmerkmal für Betreuung und Bildung in Institutionen der frühen Kindheit. Entsprechend fokussieren Weiterbildungen darauf, Wege der Professionalisierung zu finden, um die Interaktionsqualität zu verbessern. Beobachtungsstudien zur Interaktion im Kita-Alltag zeigen, dass in Interaktionen zwischen Kinderbetreuenden und Kindern Geschlechtsstereotype verstärkt werden. Für die Analyse der Interaktionen schlagen wir vor, die Konzepte des doing und undoing gender mit Dramatisierung und Dethematisierung zu kombinieren und auf der Mikroebene des Interaktionsverlaufs systematisch anzuwenden. Die Analyse der Interaktionen zwischen Kinderbetreuenden und Kindern basiert auf dem Verständnis von Geschlecht als einer fluiden kulturellen Ressource, die in Interaktionen episodisch konstruiert wird (Hirschauer 1994; Deutsch 2007; Nentwich & Kelan 2014) und derer sich Kinder und Betreuende situationsabhängig bedienen oder auch nicht.
Explicit perturbations to the stabilizer τ = i of modular $$ {A}_5^{\prime } $$ symmetry and leptonic CP violation
Authors: Wang Xin , Zhou Shun 
Published: July 2021

Abstract
In a class of neutrino mass models with modular flavor symmetries, it has been observed that CP symmetry is preserved at the fixed point (or stabilizer) of the modulus parameter τ = i, whereas significant CP violation emerges within the neighbourhood of this stabilizer. In this paper, we first construct a viable model with the modular $$ {A}_5^{\prime } $$

symmetry, and explore the phenomenological implications for lepton masses and flavor mixing. Then, we introduce explicit perturbations to the stabilizer at τ = i, and present both numerical and analytical results to understand why a small deviation from the stabilizer leads to large CP violation. As low-energy observables are very sensitive to the perturbations to model parameters, we further demonstrate that the renormalization-group running effects play an important role in confronting theoretical predictions at the high-energy scale with experimental measurements at the low-energy scale.
Muon g − 2 in gauge mediation without SUSY CP problem
Authors: Ibe Masahiro , Kobayashi Shin , Nakayama Yuhei , Shirai Satoshi 
Published: July 2021

Abstract
We discuss gauge mediated supersymmetry breaking models which explain the observed muon anomalous magnetic moment and the Higgs boson mass simultaneously. The successful explanation requires the messenger sector which violates the relation motivated by the grand unification theory (GUT). The naive violation of the GUT relation, however, ends up with the CP problem. We propose a model in which the phases of the gaugino masses are aligned despite the violation of the GUT relation. We also consider a model which generates the μ-term and the additional Higgs soft masses squared without causing CP violation. As a result, we find a successful model which explains the muon anomalous magnetic moment and the Higgs boson mass. The model is also free from the CP, flavor-changing neutral current and the lepton flavor violation problems caused by the subdominant gravity mediation effects. The lightest supersymmetric particles are gravitino/goldstini and the next-to-lightest ones are the Wino/Higgsinos in the typical parameter space. We also study the LHC constraints.
Entanglement wedge cross section inequalities from replicated geometries
Authors: Bao Ning , Chatwin-Davies Aidan , Remmen Grant N. 
Published: July 2021

Abstract
We generalize the constructions for the multipartite reflected entropy in order to construct spacetimes capable of representing multipartite entanglement wedge cross sections of differing party number as Ryu-Takayanagi surfaces on a single replicated geometry. We devise a general algorithm for such constructions for arbitrary party number and demonstrate how such methods can be used to derive novel inequalities constraining mulipartite entanglement wedge cross sections.
N3LO gravitational spin-orbit coupling at order G4
Authors: Levi Michèle , McLeod Andrew J. , von Hippel Matthew 
Published: July 2021

Abstract
In this paper we derive for the first time the N3LO gravitational spin-orbit coupling at order G4 in the post-Newtonian (PN) approximation within the effective field theory (EFT) of gravitating spinning objects. This represents the first computation in a spinning sector involving three-loop integration. We provide a comprehensive account of the topologies in the worldline picture for the computation at order G4. Our computation makes use of the publicly-available EFTofPNG code, which is extended using loop-integration techniques from particle amplitudes. We provide the results for each of the Feynman diagrams in this sector. The three-loop graphs in the worldline picture give rise to new features in the spinning sector, including divergent terms and logarithms from dimensional regularization, as well as transcendental numbers, all of which survive in the final result of the topologies at this order. This result enters at the 4.5PN order for maximally-rotating compact objects, and together with previous work in this line, paves the way for the completion of this PN accuracy.
Gravitational tests of electroweak relaxation
Authors: Barducci Daniele , Bertuzzo Enrico , Tupia Martín Arteaga 
Published: July 2021

Abstract
We consider a scenario in which the electroweak scale is stabilized via the relaxion mechanism during inflation, focussing on the case in which the back-reaction potential is generated by the confinement of new strongly interacting vector-like fermions. If the reheating temperature is sufficiently high to cause the deconfinement of the new strong interactions, the back-reaction barrier then disappears and the Universe undergoes a second relaxation phase. This phase stops when the temperature drops sufficiently for the back-reaction to form again. We identify the regions of parameter space in which the second relaxation phase does not spoil the successful stabilization of the electroweak scale. In addition, the generation of the back-reaction potential that ends the second relaxation phase can be associated to a strong first order phase transition. We then study when such transition can generate a gravitational wave signal in the range of detectability of future interferometer experiments.
TMD fragmentation functions at N3LO
Authors: Ebert Markus A. , Mistlberger Bernhard , Vita Gherardo 
Published: July 2021

Abstract
We compute the unpolarized quark and gluon transverse-momentum dependent fragmentation functions (TMDFFs) at next-to-next-to-next-to-leading order (N3LO) in perturbative QCD. The calculation is based on a relation between the TMDFF and the limit of the semi-inclusive deep inelastic scattering cross section where all final-state radiation becomes collinear to the detected hadron. The required cross section is obtained by analytically continuing our recent computation of the Drell-Yan and Higgs boson production cross section at N3LO expanded around the limit of all final-state radiation becoming collinear to one of the initial states. Our results agree with a recent independent calculation by Luo et al.
