Published: January 2020

AbstractThe aim of this paper is to provide an overview, although unnecessarily complete, of recent advances in optimal control, optimization, and game theory for networked systems. First, the recent research results and progress in optimal control and game theory for logical domain networked systems are summarized. Then, the recent developments on networked optimization and game theory for continuous domain systems are presented afterward. Finally, after introducing some recent practical applications of optimal control and game theory on networked systems, we conclude the paper with a short discussion on future research perspectives.
Monthly variation and spatial distribution of quadrant tropical cyclone size in the Western North Pacific

Published: January 2020

AbstractWith the tropical cyclone (TC) size parameter defined as the radius of 17‐m·s−1 oceanic surface wind, 225 TC cases were recorded in the western North Pacific during 2000–2009 based on the QuikSCAT near‐surface wind vector database and the best‐track dataset. In accordance with the symmetry index (the ratio of minimum and maximum quadrant sizes), the TCs were classified into symmetric and asymmetric structures. The asymmetric TCs were divided into four types: the northeast, southeast, southwest, and northwest. The spatio‐temporal characteristics of these TC types were further investigated. The monthly variation and the spatial distribution of maximum quadrant TC size exhibited significant differences among the four types. By contrast, the quadrant size of the symmetric TCs from June to November showed few changes (2.6°–2.7° latitude). It was found that the TC lifetime is an important factor affecting the quadrant TC size because of its close relationship with the activities of the western Pacific subtropical high. In addition, the climatological mean circulation also has a notable influence on the quadrant TC size through superposition of prominent background wind. Symmetric TCs are more likely to occur in the oceanic region where the background low‐level wind is the weakest.
Bottoms up: Delivering sustainable value in the base of the pyramid
Authors: Heuer Mark Alan , Khalid Usman , Seuring Stefan 
Published: January 2020

AbstractDespite a wealth of expertise involving leading institutions over at least 15 years, a base of the pyramid (BoP) model resulting in scalability has yet to emerge. We posit that institutional gaps between BoP goals of developing human and social capital on one hand and a short‐term profit focus of business on the other contribute to the lack of scalability. We address this gap by proposing a social intermediary to link the BoP with firms involved in the BoP. The social intermediary will coordinate and interpret the informal market requirements of the BoP to the firm in a “bottoms up” approach. We illustrate the bottoms up approach through a case involving Deutsche Gesellschaft fur Internationale Zusammenarbeit, a German government agency, with the garment manufacturing industry in Pakistan. The case study involves implementation of labor standards and productivity in the Pakistan garment industry, resulting in improved productivity and labor standards enabling garment manufacturers to access global supply chains.

Published: January 2020

AbstractThis paper explores the phenomenon of green prosumption with a view to theorising the phenomenon and highlighting the challenges and opportunities this particular subculture creates for marketers of green commodities. Narratives of young green prosumers were gathered from 18 phenomenological in‐depth interviews. Capturing green prosumer experiences and subjective meanings, three thematic categories of green prosumption practices, (a) contraction, (b) control, and (c) creation, are postulated in the study. It also highlights several unforeseen challenges as well as a vast array of opportunities emerging from the three green prosumer segments identified in the study: semi‐green prosumers, empowered green prosumers, and liberated green prosumers. This study provides green commodity marketers with a set of recommendations to exploit opportunities in these largely untapped market segments.

AbstractThe front cover artwork for Issue 04/2020 is a collaboration between Leibniz Institute for Catalysis (Germany) and University of Paderborn (Germany). The image illustrates that it's hard to stand just on one leg when investigating a very complex reaction. A proper bidentate coordination of a PNP ligand to a Cr complex catalyst is needed to ensure high performance in homogeneous ethylene tetramerization. The synergy between in situ EPR and XAS spectroscopy is essential to derive reliable information. See the Full Paper itself at https://doi.org/10.1002/cctc.201901441.
Exploring the latent variable space of PLS2 by post‐transformation of the score matrix (ptLV)
Authors: Stocchero Matteo 
Published: January 2020

AbstractProjection to Latent Structures (PLS) regression is largely applied in chemometrics. The most used algorithm for performing PLS is probably PLS2. PLS2 solves the problem of redundancy and collinearity in complex data sets and produces a small set of latent variables that can be used to investigate complex phenomena. However, the presence of specific cluster structures or trends in the data can drive PLS2 towards wrong directions and a redundant number of latent variables is generated. To overcome this unexpected behaviour, OSC‐based methods were developed. The main idea was to use the concept of orthogonality to identified two different type of sources of structured variation which are modeled into two different subspaces: the non‐predictive subspace described by latent variables orthogonal to the Y‐response and the predictive subspace related to the Y‐response. OSC‐based methods work on the variable space producing suitable weight vectors to project the data. In this study, a new post‐transformation method, called post‐transformation of the Latent Variable space (ptLV), is introduced. The method generates a latent space isomorphic to that discovered by PLS2 where the non‐predictive data variation is separated from the predictive one. It works on the score space and can be applied also to kernel‐PLS2 (KPLS2). The relationships with post‐transformation of PLS2 (ptPLS2) are investigated and a real and two simulated data sets are used to illustrate how ptLV works in practice.
Fast method for GA‐PLS with simultaneous feature selection and identification of optimal preprocessing technique for datasets with many observations
Authors: Stefansson Petter , Liland Kristian H. , Thiis Thomas , Burud Ingunn 
Published: January 2020

AbstractA fast and memory‐efficient new method for performing genetic algorithm partial least squares (GA‐PLS) on spectroscopic data preprocessed in multiple different ways is presented. The method, which is primarily intended for datasets containing many observations, involves preprocessing a spectral dataset with several different techniques and concatenating the different versions of the data horizontally into a design matrixXwhich is both tall and wide. The large matrix is then condensed into a substantially smaller covariance matrixXTXwhose resulting size is unrelated to the number of observations in the dataset, i.e. the height ofX. It is demonstrated that the smaller covariance matrix can be used to efficiently calibrate partial least squares (PLS) models containing feature selections from any of the involved preprocessing techniques. The method is incorporated into GA‐PLS and used to evolve variable selections for a set of different preprocessing techniques concurrently within a single algorithm. This allows a single instance of GA‐PLS to determine which preprocessing technique, within the set of considered methods, is best suited for the spectroscopic dataset. Additionally, the method allows feature selections to be evolved containing variables from a mixture of different preprocessing techniques. The benefits of the introduced GA‐PLS technique can be summarized as threefold: (1) for datasets with many observations, the proposed method is substantially faster compared to conventional GA‐PLS implementations based on NIPALS, SIMPLS, etc. (2) using a single GA‐PLS automatically reveals which of the considered preprocessing techniques results in the lowest model error. (3) it allows the exploration of highly complex solutions composed of features preprocessed using various techniques.
Corannulene‐Based Electron Acceptors: Combining Modular and Practical Synthesis with Electron Affinity and Solubility
Authors: Barát Viktor , Budanovic Maja , Tam Si Man , Huh June , Webster Richard D. , Stuparu Mihaiela C. 
Published: January 2020

AbstractIt is shown in this work that high electron affinity can be combined with high solubility and practical accessibility in corannulene‐based electron acceptors. The electron affinity originates from the presence of three different types of electron‐withdrawing groups (imide, sulfone, and trifluoromethyl) on the aromatic scaffold. The imide substituent further hosts a long alkyl chain (C18H37) to boast solubility in a wide range of organic solvents. The synthesis is modular and consists of three simple steps from a commonly available corannulene derivative with an overall isolated yield of 22–27 %.
Electrocautery ablation of anal high‐grade squamous intraepithelial lesions: Effectiveness and key factors associated with outcomes

Published: January 2020

BackgroundElectrocautery ablation (EA) is a common treatment modality for patients with anal high‐grade squamous intraepithelial lesions (HSILs), but to the authors' knowledge its effectiveness has been understudied. The objective of the current study was to determine ablation outcomes and to identify clinicopathological factors associated with postablation disease recurrence.MethodsA total of 330 people living with HIV with de novo intra‐anal HSIL who were treated with EA from 2009 to 2016 were studied retrospectively. Using long‐term, surveillance high‐resolution anoscopy biopsy data, treatment failures were classified as local recurrence (HSIL noted at the treated site at the time of surveillance) or overall recurrence (HSIL noted at treated or untreated sites). The associations between these outcomes and clinical factors were analyzed using Cox proportional hazards models.ResultsApproximately 88% of participants were men who have sex with men. The median age of study participants was 45.5 years (range, 35‐51 years) and approximately 49% had multiple index HSILs (range, 2‐6 index HSILs). At a median of 12.2 months postablation (range, 6.3‐20.9 months postablation), approximately 45% of participants had developed local recurrence whereas 60% had developed overall recurrence. Current cigarette smoking, HIV viremia (HIV‐1 RNA ≥100 copies/mL), and multiple index HSILs were found to be predictive of local recurrence. Overall recurrence was more common in current smokers and those with multiple index lesions. In multivariable models that included human papillomavirus (HPV) genotypes, baseline and persistent infections with HPV‐16 and/or HPV‐18 were found to be significantly associated with both local and overall recurrence.ConclusionsEA is an effective treatment modality for anal HSIL in people living with HIV, but rates of disease recurrence are substantial. Multiple index HSILs, HIV viremia, current cigarette smoking, and both baseline and persistent infection with HPV‐16 and/or HPV‐18 appear to negatively impact treatment success. Ongoing surveillance is imperative to capture recurrence early and improve long‐term treatment outcomes.

It has been hypothesized that besides its intraocular pressure (IOP) lowering potential, tetrahydrocannabinol (THC) may also improve ocular hemodynamics. The aim of the present study was to investigate whether single oral administration of dronabinol, a synthetic THC, alters optic nerve head blood flow (ONHBF) and its regulation in healthy subjects. The study was carried out in a randomized, placebo‐controlled, double‐masked, two‐way crossover design in 24 healthy subjects. For each study participant, 2 study days were scheduled, on which they either received capsules containing 5 mg dronabinol or placebo. ONHBF was measured with laser Doppler flowmetry at rest and while the study participants performed isometric exercise for 6 minutes to increase mean arterial blood pressure (MAP). This was repeated 1 hour after drug intake. Ocular perfusion pressure (OPP) was calculated as 2/3MAP–IOP. Dronabinol was well tolerated and no cannabinoid‐related psychoactive effects were reported. Neither administration of dronabinol nor placebo had an effect on IOP, MAP, or OPP. In contrast, dronabinol significantly increased ONHBF at rest by 9.5 ± 8.1%, whereas placebo did not show a change in ONHBF (0.3 ± 7.4% vs. baseline, P < 0.001 between study days). Dronabinol did not alter the autoregulatory response of ONHBF to isometric exercise. In conclusion, the present data indicate that low‐dose dronabinol increases ONHBF in healthy subjects without affecting IOP, OPP, or inducing psychoactive side effects. In addition, dronabinol does not alter the autoregulatory response of ONHBF to an experimental increase in OPP. Further studies are needed to investigate whether this effect can also be observed in patients with glaucoma.

Published: January 2020

AbstractYield estimations are of great interest to support interventions from governmental policies and to increase global food security. This study presents a novel model to perform in‐season corn yield predictions at the US‐county level, providing robust results under different weather and yield levels. The objectives of this study were to: (i) evaluate the performance of a random forest classification to identify corn fields using Normalized Difference Vegetation Index (NDVI), Enhanced Vegetation Index (EVI) and weather variables (temperature, precipitation, and vapor pressure deficit, VPD); (ii) evaluate the contribution of weather variables when forecasting corn yield via remote sensing data, and perform a sensitivity analysis to explore the model performance in different dates; and (iii) develop a model pipeline for performing in‐season corn yield predictions at county‐scale. Main outcomes from this study were: (i) high accuracy (87% on average) for corn field classification achieved in late August, (ii) corn yield forecasts with a mean absolute error (MAE) of 0.89 Mg ha−1, (iii) weather variables (VPD and temperature) highly influenced the model performance, and (iv) model performance decreased when predictions were performed early in the season (mid‐July), with MAE increasing from 0.87–1.36 Mg ha−1 when forecast timing changed from day of year 232–192. This research portrays the benefits of integrating statistical techniques and remote sensing to field survey data in order to perform more reliable in‐season corn yield forecasts.

Published: January 2020

AbstractThis objective of this study is to explore the influence of corporate social responsibility (CSR) on consumer's impulse buying behavior and to examine the most dominant practices for CSR which enforce to impulse buying. To check the relationship of CSR practices (environmental well‐being, social well‐being, and economic well‐being) with impulse buying, a set of hypotheses developed. Using online survey method data has been collected. The valid replies (301 responses) were processed using, CFA and SEM methods. Results indicate that environmental well‐being has a constructive relationship for trust which further leads to impulse buying and economic well‐being has a positive significant association with impulse buying directly. However, the actions of social well‐being having no impact on consumer's impulse buying behavior. By taking gender as a moderator, the actions of environmental well‐being influence positively. No effect was found for social well‐being, whereas economic well‐being was partially supported. Further, theoretical and managerial implications were discussed.

Published: January 2020

SummaryIn wireless communication systems, equalization is one of the most important schemes to improve the system performance. This paper consists of two main parts. The first part presents a blind carrier frequency offset (CFO) estimation scheme based on discrete cosine transform (DCT). The second part presents a joint low‐complexity equalization, and CFO compensation in orthogonal frequency division multiplexing (OFDM) systems. Moreover, in the second part, we present a joint low‐complexity regularized zero‐forcing (JLRZF) equalizer based on the proposed CFO estimation scheme. Simulation results show that the proposed configuration has the ability to perform blind CFO estimation and enhance the system performance in the presence of estimation errors.

Reclassification of urinary cytology regarding The Paris System for Reporting Urinary Cytology with cytohistological correlation demonstrates high sensitivity for high‐grade urothelial carcinoma
Authors: Anbardar Mohammad Hossein , Monjazeb Raha 
Published: January 2020

AbstractBackgroundRecently, The Paris System for Reporting Urinary Cytology (TPS) has led to major changes in the approach to evaluate urine cytology and pattern of reporting. The aim of this study was to reclassify urine cytology reports with TPS in order to determine the frequency of abnormal results compared with the previous system; also, we performed cytohistological correlation in abnormal cytological results.MethodsIn this study, the voided urine specimens from the patients referred to Shiraz University of Medical Sciences affiliated laboratories were retrieved and analyzed using the laboratory's electronic records system; slides prepared from the samples were reviewed by single cytopathologist blindly according to the proposed criteria of TPS.ResultsTotally, 1842 urine cytology slides from 828 patients were blindly evaluated by TPS criteria and compared with routine urine cytology classification. Then, available cytohistological correlation was done on 99 abnormal urine cytological results from 58 patients. Among the 26 cytology slides with atypical urothelial cell (AUC) in the previous classification, eight (30.70%) slides were downgraded to negative results, and four (15.30%) were upgraded to higher groups. Therefore, through the reclassification of the slides with TPS, 46% of the AUC changed to other groups. Diagnostic accuracy of the TPS classified urine cytology was 78%, including 87.88% sensitivity, 27.27% specificity, 64.44% positive predictive value, and 60% negative predictive value.ConclusionThe findings of the present study confirmed the importance and utility of TPS regarding the reclassification of AUC to other groups and its high sensitivity for detecting high‐grade urothelial carcinoma (HGUC).
Is there climate policy integration in European Union energy efficiency and renewable energy policies? Yes, no, maybe
Authors: Kettner Claudia , Kletzan‐Slamanig Daniela 
Published: January 2020

AbstractThe integration of climate policy concerns in other policy areas where decisions are taken that determine greenhouse gas emissions is a prerequisite for effectively mitigating climate change. There are particularly strong interlinkages between energy and climate policy as the major part of greenhouse gas emissions is related to energy supply and use. We compile a set of five output‐focused indicators for assessing climate policy integration (political commitment, functional overlap, policy instruments, weighting, and time perspective). We then apply the criteria for an appraisal of climate policy integration in European Union (EU) energy policy during the last decade; that is, we focus on climate policy integration from a horizontal perspective. The focus of our research lies on the comparison of the Renewable Energy and the Energy Efficiency Directives of the Energy Union Package with their predecessors. Our results show that climate change mitigation is a key objective in these documents. The energy policy objectives are generally synergetic with climate policy. The Energy Union Package makes progress in some areas like the more stringent EU targets for renewable energy and energy efficiency or the more stringent sustainability criteria for biofuels. However, some conflicting issues arise. The shift from national to an overall EU renewables target and the change towards more market‐oriented support schemes might together with the elimination of preferential grid access for renewable electricity entail negative impacts on renewable investment and on achieving emission reductions. It remains to be seen whether the adaptations in EU energy policy will lead to the required acceleration of the energy transition.
