Published: June 2020

Abstract
Climatic and environmental change in urban areas attracts more and more attention with rapid urbanization worldwide. Change in key surface climatic variables in urban areas is a core component of urban climatic change. Here we report an analysis of relative humidity (RH) change in Shijiazhuang City, China, over the period 1963–2012, based on the RH data of a typical urban station and the surrounding rural stations. We found that the annual mean RH at the urban station underwent a more significant downward trend (−0.74%/10 yr) than those at the four rural stations (−0.16%/10 yr on average), and the most significant decrease occurred after 1990s; urbanization effect on the decrease of annual mean RH at the urban station reached −0.59%/10 yr, which was highly significant, with the urbanization contribution to the overall RH decrease being 78.7%, indicating that the trend of urban drying was caused dominantly by the urbanization; urbanization effects on seasonal mean RH decrease at the urban station were −0.60%/10 yr, −0.61%/10 yr, −0.67%/10 yr and −0.46%/10 yr respectively for spring, summer, autumn and winter, which were all significant statistically, with a 100% urbanization contribution for winter; rising temperature, dropping evaporation and decreasing precipitation days relative to rural areas were found to be the main factors affecting the urban RH decrease. The conclusions are of practical significance to further understand the characteristics and causes of RH change at a typical urban meteorological station in North China, and to detect the large-scale climatic and environmental change for assessing the impact of climate change on agricultural production and water cycle.
Acoustic phonons in multilayer nitride-based AlN/GaN resonant tunneling structures

Published: June 2020

Abstract
The study of physical processes associated with acoustic phonons in nitride-based nanosystems is of great importance for the effective operation of modern nanoscale devices. In this paper, a consistent theory of acoustic phonons arising in multilayer nitride-based semiconductor resonant tunneling structures, that can function as a separate cascade of a quantum cascade laser or detector is proposed. Using the physical and geometric parameters of a typical nanostructure, the spectrum of various types of acoustic phonons and the corresponding normalized components of the elastic displacement vector are calculated. It has been established that the spectrum of acoustic phonons of a multilayer nanostructure consists of two groups of the shear phonons dependencies and three groups of dependencies for a mixed spectrum of flexural and dilatational phonons. The dependencies of the acoustic phonons spectrum of the nanostructure and the components of the elastic displacement vector on its geometric parameters are studied. It has been established that for the components of the displacement vector u
2 for shear phonons have a decrease in the absolute values of their maxima with increasing of energy level number. The components u
1 and u
3 of flexural and dilatational phonons behave respectively as symmetric and antisymmetric functions relatively the center of an separate selected layer of the nanostructure. The proposed theory can be further applied to study the interaction of electrons with acoustic phonons in multilayer resonant tunneling structures.

Connecting Work To Workers’ Social Past: A Dispositional Analysis of Police Work
Authors: Pichonnaz David 
Published: June 2020

AbstractThis article explores the impact of experiences police officers went through before they joined the Force on how they see and perform their job. I propose a new approach to police culture and practices based on a Bourdieu-inspired model of analysis, which includes its subsequent development by Lahire’s ‘dispositional analysis’. The model looks at how dispositions interiorized—particularly through the experience of social mobility and gender socialization—have a great impact on how police officers see and perform their job. The results suggest that divisions within police culture, long acknowledged by criminologists and sociologists, can be explained by the prior socialization of police officers.

Published: June 2020

Abstract
Kudiezi injection was a commonly used drug in clinical practice, contained many components and was complex in structure. In order to effectively control the quality of traditional Chinese medicine, the study established a systematic research strategy for the first time. Through the UPLC-Q-TOF/MS technology analysis, 35 chemical components in Kudiezi injection were obtained, including four major categories. Moreover, the the quantitative methods of flavonoids by HPLC and organic acids by UPLC-MS/MS were established. A variety of chromatographic techniques, with good precision, sensitivity, repeatability and solution stability were applied to the analysis of 10 batches of Kudiezi injection. Therefore, the quality control of Kudiezi injection was a reliable and effective method, which can provide ideas for the qualitative and quantitative study of chemical constituents in other complex Chinese medicines.
Immune Immunomodulation in Coronavirus Disease 2019 (COVID-19): Strategic Considerations for Personalized Therapeutic Intervention
Authors: Hall Mark W , Joshi Ila , Leal Luis , Ooi Eng Eong 
Published: June 2020

Abstract
We are learning that the host response to severe acute respiratory syndrome coronavirus 2 ( SARS-CoV-2) infection is complex and highly dynamic. Effective initial host defense in the lung is associated with mild symptoms and disease resolution. Viral evasion of the immune response can lead to refractory alveolar damage, ineffective lung repair mechanisms, and systemic inflammation with associated organ dysfunction. The immune response in these patients is highly variable and can include moderate to severe systemic inflammation and/or marked systemic immune suppression. There is unlikely to be a “one size fits all” approach to immunomodulation in patients with coronavirus disease 2019 (COVID-19). We believe that a personalized, immunophenotype-driven approach to immunomodulation that may include anticytokine therapy in carefully selected patients and immunostimulatory therapies in others is the shortest path to success in the study and treatment of patients with critical illness due to COVID-19.

Abstract
Chiococca alba (L.) Hitchc. (snowberry), a member of the Rubiaceae, has been used as a folk remedy for a range of health issues including inflammation and rheumatism and produces a wealth of specialized metabolites including terpenes, alkaloids, and flavonoids. We generated a 558 Mb draft genome assembly for snowberry which encodes 28,707 high-confidence genes. Comparative analyses with other angiosperm genomes revealed enrichment in snowberry of lineage-specific genes involved in specialized metabolism. Synteny between snowberry and Coffea canephora Pierre ex A. Froehner (coffee) was evident, including the chromosomal region encoding caffeine biosynthesis in coffee, albeit syntelogs of N-methyltransferase were absent in snowberry. A total of 27 putative terpene synthase genes were identified, including 10 that encode diterpene synthases. Functional validation of a subset of putative terpene synthases revealed that combinations of diterpene synthases yielded access to products of both general and specialized metabolism. Specifically, we identified plausible intermediates in the biosynthesis of merilactone and ribenone, structurally unique antimicrobial diterpene natural products. Access to the C. alba genome will enable additional characterization of biosynthetic pathways responsible for health-promoting compounds in this medicinal species.
An Herbivore-Induced Plant Volatile From Saltcedar (Tamarix spp.) Is Repellent to Diorhabda carinulata (Coleoptera: Chrysomelidae)

Abstract
The leaf beetle Diorhabda carinulata Desbrochers (Coleoptera: Chrysomelidae) was introduced into the United States in 1999 for classical biological control of the exotic woody invader saltcedar (Tamarix spp. L. [Caryophyllales: Tamaricaceae]). The recent southern expansion of the range of D. carinulata in the United States has precipitated conflict between proponents of biological control of Tamarix and those with concerns over habitat conservation for avian species. Several semiochemicals that mediate aggregations by this species have been reported, but no repellent compounds have been recorded thus far. We now report a repellent compound, 4-oxo-(E)-2-hexenal, induced by adult D. carinulata feeding on saltcedar foliage. Collection of headspace volatiles, gas chromatography mass spectrometry, and electroantennographic analyses identified 4-oxo-(E)-2-hexenal as an insect-induced compound that is antennally active. Behavioral and exposure assays were conducted to test for repellency and toxicity in adults and larvae. Headspace volatiles were also collected from adult males exposed to 4-oxo-(E)-2-hexenal to determine the impact exposure might have on the emission of the aggregation pheromone. 4-Oxo-(E)-2-hexenal elicited electrophysiological responses in adults of both sexes. Behavioral responses indicated repellency across multiple doses for reproductive D. carinulata adults but not in nonreproductive adults. Exposure assays indicated altered behaviors in first instar larvae and adults, but not in third instar larvae. Collection of headspace volatiles indicated that exposure to 4-oxo-(E)-2-hexenal did not alter emission of the D. carinulata aggregation pheromone by adult males. The continued development and field deployment of this repellent compound may provide a new tool for the management of D. carinulata.

Published: June 2020

Abstractl-Fucose and l-fucose-containing polysaccharides, glycoproteins or glycolipids play an important role in a variety of biological processes. l-Fucose-containing glycoconjugates have been implicated in many diseases including cancer and rheumatoid arthritis. Interest in fucose and its derivatives is growing in cancer research, glyco-immunology, and the study of host–pathogen interactions. l-Fucose can be extracted from bacterial and algal polysaccharides or produced (bio)synthetically. While deuterated glucose and galactose are available, and are of high interest for metabolic studies and biophysical studies, deuterated fucose is not easily available. Here, we describe the production of perdeuterated l-fucose, using glyco-engineered Escherichia coli in a bioreactor with the use of a deuterium oxide-based growth medium and a deuterated carbon source. The final yield was 0.2 g L−1 of deuterated sugar, which was fully characterized by mass spectrometry and nuclear magnetic resonance spectroscopy. We anticipate that the perdeuterated fucose produced in this way will have numerous applications in structural biology where techniques such as NMR, solution neutron scattering and neutron crystallography are widely used. In the case of neutron macromolecular crystallography, the availability of perdeuterated fucose can be exploited in identifying the details of its interaction with protein receptors and notably the hydrogen bonding network around the carbohydrate binding site.

Abstract
Globally, obstetric haemorrhage (OH) remains the leading cause of maternal mortality. Much of the associated mortality is ascribed to challenges surrounding deployment of innovations rather than lack of availability. In low- and middle-income countries (LMICs), where the burden is highest, there is a growing interest in implementation research as a means to bridge the ‘know–do’ gap between proven interventions and their reliable implementation at scale. In this systematic review, we identified and synthesized qualitative and quantitative data across the implementation outcomes of OH prevention innovations in LMICs using a taxonomy developed by Proctor et al. We also identified service outcomes for the included innovations, as well as implementation strategies and implementation facilitators and barriers. Eligible studies were empirical, focused on the implementation of OH prevention programmes or policies and occurred in an LMIC. Eight databases were searched. Two authors independently assessed studies for selection and extracted data; the first author resolved discrepancies. Narrative synthesis was used to analyse and interpret the findings. Studies were predominantly focused in Africa and on primary prevention. Interventions included prophylactic use of uterotonics (n = 7), clinical provider skills training (n = 4) and provision of clinical guidelines (n = 1); some (n = 3) were also part of a multi-component quality improvement bundle. Various barriers were reported, including challenges among intervention beneficiaries, providers and within the health system; however, studies reported the development and testing of practical implementation solutions. These included training and monitoring of implementers, community and stakeholder engagement and guidance by external mentors. Some studies linked successful delivery to implementation outcomes, most commonly adoption and acceptability, but also feasibility, penetration and sustainability. Findings suggest that innovations to prevent OH can be acceptable, appropriate and feasible in LMIC settings; however, more research is needed to better evaluate these and other under-reported implementation outcomes.
Marvels of the Levant: Print Media and the Politics of Wonder in Early Modern Venice
Authors: Stouraiti Anastasia 
Published: June 2020

Abstract
This article uses the strange and marvellous as a heuristic device to study the relationship between emotions, media and politics in early modern Venice. In particular, it examines how printed news about the marvels of the Levant mediated Venice’s encounters with its colonial subjects and imperial rivals, and analyses the role of wonder and imagination in the creation of an imperial community of feelings. The article argues that a focus on the affective politics of the marvellous can shed new light on the emotional dimensions of the early modern Venetian public sphere and its links with war and empire-building.
Taking uncertainty seriously: simplicity versus complexity in financial regulation

Published: June 2020

AbstractDistinguishing between risk and uncertainty, this article draws on the psychological literature on heuristics to consider whether and when simpler approaches may outperform more complex methods for modeling and regulating the financial system. We find that: simple methods can sometimes dominate more complex modeling approaches for calculating banks’ capital requirements, especially when data are limited or underlying risks are fat-tailed; simple indicators often outperformed more complex metrics in predicting individual bank failure during the global financial crisis; when combining different indicators to predict bank failure, simple and easy-to-communicate “fast-and-frugal” decision trees can perform comparably to standard, but more information-intensive, regressions. Taken together, our analyses suggest that because financial systems are better characterized by uncertainty than by risk, simpler approaches to modeling and regulating financial systems can usefully complement more complex ones and ultimately contribute to a safer financial system.
A second-order discretization for degenerate systems of stochastic differential equations
Authors: Iguchi Yuga , Yamada Toshihiro 
Published: June 2020

Abstract
The paper proposes a new second-order weak approximation scheme for hypoelliptic diffusions or degenerate systems of stochastic differential equations satisfying a certain Hörmander condition. The scheme is constructed by a Gaussian process and a stochastic polynomial weight through a technique based on Malliavin calculus, and is implemented by a Monte Carlo method and a quasi-Monte Carlo method. A variance analysis for the Monte Carlo method is discussed, and further control variate methods are introduced to reduce the variance. The effectiveness of the proposed scheme is illustrated through numerical experiments for some hypoelliptic diffusions.

Published: June 2020

AbstractNutrition is a critical component of acute burn care and wound healing. There is no consensus over the appropriate timing of initiating enteral nutrition in geriatric burn patients. This study aimed to assess the impact of early enteral nutrition on outcomes in this patient population. We performed a 1-year (2017) analysis of the American College of Surgeons Trauma Quality Improvement Program and included all older adult (age ≥65 years) isolated thermal burn patients who were admitted for more than 24 hr and received enteral nutrition. Patients were stratified into two groups based on the timing of initiation of feeding: early (≤24 hr) vs late (&gt;24 hr). Multivariate logistic regression was performed to control for potential confounding factors. Outcome measures were hospital and intensive care unit lengths of stay, in-hospital complications, and mortality. A total of 1,004,440 trauma patients were analyzed, of which 324 patients were included (early: 90 vs late: 234). The mean age was 73.9 years and mean TBSA burnt was 31%. Patients in the early enteral nutrition group had significantly lower rates of in-hospital complications and mortality (15.6% vs 26.1%; P = 0.044), and a shorter hospital length of stay (17 [11,23] days vs 20 [14,24] days; P = 0.042) and intensive care unit length of stay (13 [8,15] days vs 17 [9,21] days; P = 0.042). In our regression model of geriatric burn patients, early enteral nutrition was associated with improved outcomes. The cumulative benefits observed may warrant incorporating early enteral nutrition as part of intensive care protocols.
Medial-ABC: an algorithm for the correspondence between myocardium and coronary artery mesh models based on the medial axis of coronary artery
Authors: Cha Jehyun , Ryu Joonghyun , Choi Jin-Ho , Kim Deok-Soo 
Published: June 2020

AbstractThe role of coronary arteries is to supply sufficient blood to myocardium. Obstruction of coronary arteries limits blood supply and causes myocardial ischemia or acute myocardial infarction, a major cause of human death. Hence, the quantification of the regional amount of heart muscle subtended by obstructed coronary arteries is of critical value in clinical medicine. However, conventional methods are inaccurate and frequently disagree with clinical practice. This study proposes a novel medial-axis-based correspondence (Medial-ABC) algorithm to find the correspondence between myocardium and coronary artery in order to segment regional myocardium at risk subtended by any potentially obstructed coronary artery. Given the triangular mesh models of coronary artery and myocardium, the proposed algorithm (i) computes the medial axis of coronary artery, (ii) finds the correspondence using the medial axis of coronary artery, and (iii) segments the coronary artery and myocardium. The proposed algorithm provides a robust mathematical linkage between myocardium at risk and supplying coronary arteries so that ischemic myocardial regions can be accurately identified. Hence, both the extent and severity of myocardial ischemia can be quantified effectively, efficiently, and accurately. Furthermore, the constructed mesh model of segmented coronary artery and myocardium can be post-processed for applications such as building optimization models of cardiac systems. The CardiacVis program, which implements the Medial-ABC algorithm, is freely available at Voronoi Diagram Research Center (http://voronoi.hanyang.ac.kr/software/cardiacvis) and will be an invaluable tool for quantitative patient-specific risk stratification in clinical practice.

Abstract
Spontaneous pneumothorax occurring in patients with pulmonary arteriovenous malformations (PAVMs) caused by hereditary hemorrhagic telangiectasia (HHT) is extremely rare. We report a case of spontaneous pneumothorax in a PAVM patient. A 26-year-old man with previously diagnosed HHT and multiple small PAVMs presented with chest pain and dyspnea and was referred to our hospital. Chest X-ray showed a left-sided pneumothorax. Computed tomography (CT) showed apical bullae on both sides of the upper lobe. We clarified the location of PAVMs by 3D-CT to avoid the massive bleeding caused by careless grasping of PAVMs and unintentional incomplete resection of the PAVMs during the pneumothorax surgery. Considering the risk of exacerbation, the patient underwent bullectomy of the left upper lobe. The postoperative histopathological examination indicated that the pneumothorax occurred spontaneously in the HHT patient. We should clarify the location of PAVMs to avoid bleeding caused by the grasping of PAVMs during surgery.
