Authors: Dai Ruoyun , Cheong Weng‐Chon , Jiao Jiqing , Zhang Chao , Zhang Yu , Chen Zheng , Nan Caiyun , Chen Chen 
Published: September 2020

AbstractHollow nanomaterials consisting of non‐noble metal oxides have wide applications in catalysis, and many preparation methods for this kind of structures are established. However, it is still challenging to fabricate non‐noble‐metal hollow structures featuring high crystallinity, regular polyhedral morphologies, and small sizes, owing to their relatively low chemical stability and the stringent hollowing conditions. Here in this work, an optimized self‐templating synthesis method with refined control over the heating program and solution environment, which can alleviate the common issues of morphology and crystallinity degradation from precursors during hollowing process, is reported. Through this method, highly crystalline Cu2O nanobox with sizes below 50 nm is successfully prepared. Benefiting from the unique hollow structures, the Cu2O nanobox/C catalyst gives outstanding performances in catalyzing the oxidative homocoupling of phenylacetylene, with the advantages of lower metal loading, mild reaction conditions, and no additives. This optimized method can be extended to the preparation of other non‐noble‐metal hollow materials with sophisticated architectures.
Luxury rental purchase intention among millennials—A cross‐national study
Authors: Mishra Sita , Jain Sheetal , Jham Vimi 
Published: September 2020

AbstractIn the last few years, a radical shift has been observed in luxury consumption behavior, particularly in millennials who are increasingly inclined toward sustainability. There has been a tremendous rise in demand for services providing a non‐ownership model of consumption. However, hardly any study has focused on exploring the consumption behavior of the millennials for luxury fashion goods in the context of sharing economy. Hence, this research aims to examine the key drivers that affect millennials attitude and purchase intention of luxury fashion on rent. Data were collected via mall‐intercept questionnaire survey method from millennials in India and United Arab Emirates (UAE) who aspired to consume luxury fashion goods on rental basis. Statistical tests, including confirmatory factor analysis, multi‐group analysis, and structural equation modeling, were applied for data analysis. Furthermore, an integrated conceptual model based on self‐determination theory and theory of reasoned action is proposed to examine the key driving motivators that affect millennials' attitude and purchase intention of luxury fashion on rent in the UAE and India. The results reveal that significant differences exist across the nations. Experience value and identity projection value had a higher impact on UAE citizens than Indians. The current study is a pioneer study that attempted to understand the young consumer's attitude and purchase intention for luxury fashion rental consumption and examine differences and similarities of millennials across nations.

AbstractVerticillium wilt, a soil‐borne disease caused by the fungal pathogen Verticillium dahliae, threatens strawberry (Fragaria × ananassa) production worldwide. The development of resistant cultivars has been a persistent challenge, in part because the genetics of resistance is complex. The heritability of resistance and genetic gains in breeding for resistance to this pathogen have not been well documented. To elucidate the genetics, assess long‐term genetic gains, and estimate the accuracy of genomic selection for resistance to Verticillium wilt, we analyzed a genetically diverse population of elite and exotic germplasm accessions (n = 984), including 245 cultivars developed since 1854. We observed a full range of phenotypes, from highly susceptible to highly resistant: < 3% were classified as highly resistant, whereas > 50% were classified as moderately to highly susceptible. Broad‐sense heritability estimates ranged from 0.70–0.76, whereas narrow‐sense genomic heritability estimates ranged from 0.33–0.45. We found that genetic gains in breeding for resistance to Verticillium wilt have been negative over the last 165 years (mean resistance has decreased over time). We identified several highly resistant accessions that might harbor favorable alleles that are either rare or non‐existent in modern populations. We did not observe the segregation of large‐effect loci. The accuracy of genomic predictions ranged from 0.38–0.53 among years and whole‐genome regression methods. We show that genomic selection has promise for increasing genetic gains and accelerating the development of resistant cultivars in strawberry by shortening selection cycles and enabling selection in early developmental stages without phenotyping.
Two bonded half‐planes with a parabolic inclusion
Authors: Wang Xu , Schiavone Peter 
Published: September 2020

AbstractIn this paper, primarily with the aid of analytic continuation, we derive analytic solutions for Eshelby's problem of a parabolic inclusion undergoing uniform anti‐plane and in‐plane eigenstrains located in one of two well‐bonded dissimilar elastic half‐planes. We obtain elementary expressions of the analytic functions defined in all three phases characterizing the elastic fields representing displacements, strains and stresses in the composite.

We analyze representations and their characters in detail and find surprisingly simple character formulas for the representations in the generic parameter regime that admit an elegant combinatorial formulation. We also discuss truncations of the algebra and give a conjectural formula for the complete set of truncation curves. We develop a theory of gluing for these algebras in order to build more complicated coset and non-coset algebras. We demonstrate the power of this technology with some examples and show in particular that the $$ \mathcal{N} $$
N
= 2 supersymmetric Grassmannian can be obtained by gluing three bosonic Grassmannian algebras in a loop. We finally speculate about the tantalizing possibility that this algebra is a specialization of an even larger 4-parametric family of algebras exhibiting pentality symmetry. Specializations of this conjectural family should include both the unitary Grassmannian family as well as the Lagrangian Grassmannian family of VOAs which interpolates between the unitary and the orthosymplectic cosets.

Correlation functions of symmetric orbifold from AdS3 string theory
Authors: Hikida Yasuaki , Liu Tianshu 
Published: September 2020

Abstract
The paper examines correspondence among correlation functions of symmetric orbifold and string theory on AdS3 described by sl(2) Wess-Zumino-Novikov-Witten (WZNW) model. We start by writing down n-point function of twist operators in the symmetric orbifold in terms of the data of effective Riemann surface. It is then shown that the correlation function can be reproduced from the sl(2) WZNW model. The computation is based on the claim that string worldsheet is given by the same Riemann surface and the reduction method from sl(2) WZNW model to Liouville field theory. We first consider the genus zero surface and then generalize the analysis to the case of generic genus. The radius of AdS3 is related to the level k of the WZNW model. For k = 3, our result should be an important ingredient for deriving AdS3/CFT2 correspondence with tensionless superstrings to all orders in string perturbation theory. For generic k, relations involving specific forms of correlation functions for strings on AdS3× X were obtained.

Abstract
Aims/hypothesis
The risk of complications and medical consequences of type 2 diabetes are well known. Hospital costs have been identified as a key driver of total costs in studies of the economic burden of type 2 diabetes. Less evidence has been generated on the impact of individual diabetic complications on the overall societal burden. The objective of this study was to analyse costs of hospital-based healthcare (inpatient and outpatient care) and work absence related to individual macrovascular and microvascular complications of type 2 diabetes in Sweden in 2016.

Methods
Data for 2016 were retrieved from a Swedish national retrospective observational database cross-linking individual-level data for 1997–2016. The database contained information from population-based health, social insurance and socioeconomic registers for 392,200 people with type 2 diabetes and matched control participants (5:1). Presence of type 2 diabetes and of diabetes complications were derived using all years, 1997–2016. Costs of hospital-based care and of absence from work due to diabetes complications were estimated for the year 2016. Regression analysis was used for comparison with control participants to attribute absence from work to individual complications, and to account for joint presence of complications.

Results
Use of hospital care for complications was higher in type 2 diabetes compared with control participants in 2016: 26% vs 12% had ≥1 hospital contact; there were 86,104 vs 24,608 outpatient visits per 100,000 people; and there were 9894 vs 2546 inpatient admissions per 100,000 people (all p < 0.001). The corresponding total costs of hospital-based care for complications were €919 vs €232 per person (p < 0.001), and 74.7% of costs were then directly attributed to diabetes (€687 per person). Regression analyses distributed the costs of days absent from work across diabetes complications per se, basic type 2 diabetes effect and unattributed causes. Diabetes complications amounted to €1317 per person in 2016, accounting for possible complex interactions (25% of total costs of days absent). Key drivers of costs were the macrovascular complications angina pectoris, heart failure and stroke; and the microvascular complications eye diseases, including retinopathy, kidney disease and neuropathy. Early mortality in working ages cost an additional €579 per person and medications used in risk-factor treatment amounted to €418 per person.

Conclusions/interpretation
The economic burden of complications in type 2 diabetes is substantial. Costs of absence from work in this study were found to be greater than of hospital-based care, highlighting the need for considering treatment consequences in a societal perspective in research and policy.

Nature-inspired optimization of tubular joints for metal 3D printing
Authors: Kanyilmaz Alper , Berto Filippo , Paoletti Ingrid , Caringal Ric Joseph , Mora Samantha 
Published: September 2020

AbstractSteel tubular frames are often used to build a variety of structures because of their optimal mechanical properties and attractive forms. However, their joint fabrication involves a vast quantity of cutting and welding works, which induces high labour costs, material waste, and environmental pollution. The construction industry dominates the global carbon footprint, and it needs more sustainable products. Nature’s structures are also often tubular, and their joints (e.g. the knees of a human body, the nodes of trees and plants) are intrinsically optimized to maximize stiffness, resistance, and robustness. The 3D metal printing technology can enable a nature-inspired optimization of steel tubular joints, saving material waste and decreasing fabrication costs as well as the carbon footprint of the sector, since it is free from the constraints of traditional manufacturing. In this study, we designed new tubular joint shapes using solid isotropic material with the penalization (SIMP) method. The objective of the optimization was to maximize the structural performance of the node. The optimized node that used to be achieved after a complex manufacturing process composed of numerous cutting and welding operations, can now be 3D printed and then connected to the rest of the joint leading to a shorter fabrication time. We quantified the joints’ structural performance with different grades of optimization using non-linear finite element analysis. Compared with the conventional joint shapes, the new geometries offered a higher stiffness, resistance, and robustness. We performed a powder bed fusion simulation to analyze the residual stresses after production, and estimated the cost of the new solutions.
Towards the formalization of non-functional requirements in conceptual design
Authors: Shankar Prabhu , Morkos Beshoy , Yadav Darshan , Summers Joshua D. 
Published: September 2020

AbstractThis paper explores the formal roles of non-functional requirements’ (NFR) elicitation, definition, and verification in the early stages of an engineering design project. This is performed using a case study conducted at an automotive original equipment manufacturer (OEM) during the design and development of a rear bumper sub-system. The purpose of this exploration is to determine if NFRs should be formalized within requirements modeling scheme. This can capture conceptual design information to identify their impact on other requirements while conducting design changes. The modeling scheme in this paper consists of a sequence of following domains—requirements, functions, working principle, components, design parameters, test measures, and tests—that are mapped to each other using matrices. It is revealed through this case study that non-functional requirements drive much of the design decision-making process and constrain the manner in which the product functionality is realized. Hence, the inclusion of NFRs as a separate and distinct domain in the design process is critical to recognize their significance during design changes. Based on the observations made in the case study, the NFR domain is included in the requirements modeling scheme.
Mechanical allodynia triggered by cold exposure in mice with the Scn11a p.R222S mutation: a novel model of drug therapy for neuropathic pain related to NaV1.9

Published: September 2020

AbstractMutations within the SCN11A gene which encodes the voltage-gated sodium channel NaV1.9 mainly expressed in small fiber sensory neurons have been associated with neuropathic disorders; however, suitable medications have not been fully investigated. To develop drug therapies against NaV1.9-related neuropathic pain, we aimed to establish a novel model using mice carrying the Scn11a p.R222S mutation initially identified in patients with familial episodic limb pain that is characterized by paroxysmal pain induced by fatigue or bad weather conditions. We investigated the influence of cold exposure (4 °C, overnight) on the behavioral and biochemical phenotypes of Scn11a p.R222S mutant (R222S) and wild type C57BL/6N (WT) mice. We also tested the effects of acetaminophen (125, 250 mg/kg, perorally, p.o.) and traditional Japanese medicine, goshajinkigan (0.5 or 1.0 g/kg, p.o.), which are analgesic drugs prescribed to patients with neuropathic pain, in this model of cold-induced mechanical allodynia in R222S mice.Cold-exposed R222S mice exhibited enhanced mechanical allodynia and thermal hypersensitivity compared with WT mice. The decrease of the mechanical withdrawal threshold in R222S mice was reversible 24 h after housing at room temperature. There was no significant change in the levels of interleukin-1β, interleukin-6, tumor necrosis factor-α, or interferon-γ in the plasma or spinal cords of WT and R222S mice after cold exposure. Both acetaminophen (250 mg/kg) and goshajinkigan (1.0 g/kg) significantly attenuated mechanical allodynia in R222S mice. The model of cold-induced mechanical allodynia in mice with the Scn11a p.R222S mutation is novel and useful for evaluating analgesic drugs for intractable neuropathies related to NaV1.9.
Discrete Symmetries of Complete Intersection Calabi–Yau Manifolds
Authors: Lukas Andre , Mishra Challenger 
Published: September 2020

AbstractIn this paper, we classify non-freely acting discrete symmetries of complete intersection Calabi–Yau manifolds and their quotients by freely-acting symmetries. These non-freely acting symmetries can appear as symmetries of low-energy theories resulting from string compactifications on these Calabi–Yau manifolds, particularly in the context of the heterotic string. Hence, our results are relevant for four-dimensional model building with discrete symmetries and they give an indication which symmetries of this kind can be expected from string theory. For the 1695 known quotients of complete intersection manifolds by freely-acting discrete symmetries, non-freely-acting, generic symmetries arise in 381 cases and are, therefore, a relatively common feature of these manifolds. We find that 9 different discrete groups appear, ranging in group order from 2 to 18, and that both regular symmetries and R-symmetries are possible.

Abstract
Purpose
Increased angiogenesis after myocardial infarction is considered an important favorable prognostic parameter. The αvβ3 integrin is a key mediator of cell-cell and cell-matrix interactions and an important molecular target for imaging of neovasculature and repair processes after MI. Thus, imaging of αvβ3 expression might provide a novel biomarker for assessment of myocardial angiogenesis as a prognostic marker of left ventricular remodeling after MI. Currently, there is limited data available regarding the association of myocardial blood flow and αvβ3 integrin expression after myocardial infarction in humans.

Methods
Twelve patients were examined 31 ± 14 days after MI with PET/CT using [18F]Galacto-RGD and [13N]NH3 and with cardiac MRI including late enhancement on the same day. Normal myocardium (remote) and areas of infarction (lesion) were identified on the [18F]Galacto-RGD PET/CT images by correlation with [13N]NH3 PET and cardiac MRI. Lesion/liver-, lesion/blood-, and lesion/remote ratios were calculated. Blood flow and [18F]Galacto-RGD uptake were quantified and correlated for each myocardial segment (AHA 17-segment model).

Results
In 5 patients, increased [18F]Galacto-RGD uptake was notable within or adjacent to the infarction areas with a lesion/remote ratio of 46% (26–83%; lesion/blood 1.15 ± 0.06; lesion/liver 0.61 ± 0.18). [18F]Galacto-RGD uptake correlated significantly with infarct size (R = 0.73; p = 0.016). Moreover, it correlated significantly with restricted blood flow for all myocardial segments (R = − 0.39; p < 0.0001) and even stronger in severely hypoperfused areas (R = − 0.75; p < 0.0001).

Conclusion
[18F]Galacto-RGD PET/CT allows the visualization and quantification of myocardial αvβ3 expression as a key player in angiogenesis in a subset of patients after MI. αvβ3 expression was more pronounced in patients with larger infarcts and was generally more intense but not restricted to areas with more impaired blood flow, proving that tracer uptake was largely independent of unspecific perfusion effects. Based on these promising results, larger prospective studies are warranted to evaluate the potential of αvβ3 imaging for assessment of myocardial angiogenesis and prediction of ventricular remodeling.
Estimation of the National Surgical Needs in India by Enumerating the Surgical Procedures in an Urban Community Under Universal Health Coverage

Published: September 2020

AbstractBackground11% of the global burden of disease requires surgical care or anaesthesia management or both. Some studies have estimated this burden to be as high as 30%. The Lancet Commission for Global Surgery (LCoGS) estimated that 5000 surgeries are required to meet the surgical burden of disease for 100,000 people in LMICs. Studies from LMICs, estimating surgical burden based on enumeration of surgeries, are sparse.MethodWe performed this study in an urban population availing employees’ heath scheme in Mumbai, India. Surgical procedures performed in 2017 and 2018, under this free and equitable health scheme, were enumerated. We estimated the surgical needs for national population, based on age and sex distribution of surgeries and age standardization from our cohort.ResultA total of 4642 surgeries were performed per year for a population of 88,273. Cataract (22.8%), Caesareans (3.8%), surgeries for fractures (3.27%) and hernia (2.86%) were the commonest surgeries. 44.2% of surgeries belonged to the essential surgeries. We estimated 3646 surgeries would be required per 100,000 Indian population per year. One‐third of these surgeries would be needed for the age group 30–49 years, in the Indian population.ConclusionA total of 3646 surgeries were estimated annually to meet the surgical needs of Indian population as compared to the global estimate of 5000 surgeries per 100,000 people. Caesarean section, cataract, surgeries for fractures and hernia are the major contributors to the surgical needs. More enumeration‐based studies are needed for better estimates from rural as well as other urban areas.
