Phenolic acid content and in vitro antioxidant capacity of einkorn water biscuits as affected by baking time
Authors: Santa Cruz Olivos Juan Edgar , De Noni Ivano , Hidalgo Alyssa , Brandolini Andrea , Yilmaz Volkan Arif , Cattaneo Stefano , Ragg Enzio M. 
Published: December 2020

AbstractAim of this research was to study the evolution of heat damage, phenolic acid content and in vitro antioxidant capacity of whole meal einkorn water biscuits baked at 205 °C for increasing times (10 min steps) from 25 to 75 min. The heat damage was gauged by determining furosine, hydroxymethylfurfural (HMF), furfural and glucosylisomaltol (GLI) contents. Furosine increased up to 50 min baking, when HMF started to form; furfural augmented only after 65 min treatment, whereas GLI did not change. An unknown compound, apparently related to the severity of the heat load, aroses through the aldolic condensation of HMF with the acetone used for the extraction of phenolic acids; hence the use of acetone-based solvents in thermally processed cereal products should be avoided. The conjugated phenolic acids ferulic, vanillic, syringic, p-coumaric, p-hydroxybenzoic and syringaldehyde and the bound phenolic acids ferulic, p-coumaric, syringic, and p-hydroxybenzoic were identified in water biscuits. The stronger heating treatments led to an increase of the soluble conjugated compounds, but did not influence the bound fraction. The in vitro antioxidant capacity of water biscuits augmented significantly as baking time increased, likely for the formation of antioxidant compounds as a consequence of heat damage.
Singularity of the Spectrum for Smooth Area-Preserving Flows in Genus Two and Translation Surfaces Well Approximated by Cylinders
Authors: Chaika Jon , Frączek Krzysztof , Kanigowski Adam , Ulcigrai Corinna 
Published: December 2020

AbstractWe consider smooth flows preserving a smooth invariant measure, or, equivalently, locally Hamiltonian flows on compact orientable surfaces and show that, when the genus of the surface is two, almost every such locally Hamiltonian flow with two non-degenerate isomorphic saddles has singular spectrum. More in general, singularity of the spectrum holds for special flows over a full measure set of interval exchange transformations with a hyperelliptic permutation (of any number of exchanged intervals), under a roof with symmetric logarithmic singularities. The result is proved using a criterion for singularity based on tightness of Birkhoff sums with exponential tails decay. A key ingredient in the proof, which is of independent interest, is a result on translation surfaces well approximated by single cylinders. We show that for almost every translation surface in any connected component of any stratum there exists a full measure set of directions which can be well approximated by a single cylinder of area arbitrarily close to one. The result, in the special case of the stratum $$\mathcal {H}(1,1)$$

Abstract
Purpose
More and more people survive cancer, but the disease and its treatment often lead to impairment. Multidisciplinary ambulatory oncological rehabilitation (OR) programs have thus been developed. SW!SS REHA, the organization of major Swiss rehabilitation clinics, has defined ambulatory OR quality criteria for its members (about 50% of the Swiss rehabilitation capacity). However, SW!SS REHA criteria are not fully implemented and/or interpreted differently by different specialties or in different linguistic regions in Switzerland. The aim of our study was to carry out an online survey of existing outpatient programs to define quality criteria for an ideal OR program in Switzerland.

Methods
A mixed methods approach was used for the survey—qualitative and quantitative. The qualitative part consisted of a guided discussion with OR experts and the quantitative part of an online survey. The quantitative part comprised the development and evaluation of an online questionnaire. It served to record the opinions of OR centers in Switzerland on the desired situation of outpatient rehabilitation.

Results
Eighteen OR centers and 71 (49.7% response rate) OR actors participated in the online survey. The survey results indicate that some of the SW!SS REHA quality and performance criteria only partially match with the desired OR criteria for Switzerland. Key disparities occur particularly in the program design and structure and specifically around how many interventions are required to constitute an OR program, the extent of standardization versus individualization of the program, i.e., how many and which modules in a program should be obligatory, and finally the duration and intensity of the program. The online survey did not generate any statistical evidence that OR requirements vary significantly between different linguistic regions and among different specialties.

Conclusions
Cancer patients are heterogeneous with respect to cancer type, prognosis, and disability level, such that a standard program cannot be uniformly applied. Therefore, a flexible program is required with few mandatory modules and additional individual modules to achieve the threshold number of modules that would constitute a multidisciplinary OR program. Intensity and frequency of OR needs to consider the health state of the participants. The results indicate a need to modify some of the existing SW!SS REHA criteria to ensure that more patients can gain access and benefit form evidence-based OR interventions. Furthermore, the survey provides important findings so that the existing OR offer can be improved with the goal that OR centers will be able to be quality certified in the future.
Proximity measures based on KKT points for constrained multi-objective optimization
Authors: Eichfelder Gabriele , Warnow Leo 
Published: December 2020

AbstractAn important aspect of optimization algorithms, for instance evolutionary algorithms, are termination criteria that measure the proximity of the found solution to the optimal solution set. A frequently used approach is the numerical verification of necessary optimality conditions such as the Karush–Kuhn–Tucker (KKT) conditions. In this paper, we present a proximity measure which characterizes the violation of the KKT conditions. It can be computed easily and is continuous in every efficient solution. Hence, it can be used as an indicator for the proximity of a certain point to the set of efficient (Edgeworth-Pareto-minimal) solutions and is well suited for algorithmic use due to its continuity properties. This is especially useful within evolutionary algorithms for candidate selection and termination, which we also illustrate numerically for some test problems.
Set-Valued Functions of Bounded Generalized Variation and Set-Valued Young Integrals
Authors: Michta Mariusz , Motyl Jerzy 
Published: December 2020

AbstractThe paper deals with some properties of set-valued functions having bounded Riesz p-variation. Set-valued integrals of Young type for such multifunctions are introduced. Selection results and properties of such set-valued integrals are discussed. These integrals contain as a particular case set-valued stochastic integrals with respect to a fractional Brownian motion, and therefore, their properties are crucial for the investigation of solutions to stochastic differential inclusions driven by a fractional Brownian motion.
Nonlinear vibration of a lumped system with springs-in-series
Authors: Awrejcewicz Jan , Starosta Roman , Sypniewska-Kamińska Grażyna 
Published: December 2020

AbstractThe paper deals with the dynamics of a lumped mass mechanical system containing two nonlinear springs connected in series. The external harmonic excitation, linear and nonlinear damping are included into considerations. The mathematical model contains both differential and algebraic equations, so it belongs to the class of dynamical systems governed by the differential–algebraic system of equations (DAEs). An approximate analytical approach is used to solve the initial value problem for the DAEs. We adopt the multiple scales method (MSM) that allows one to obtain the sufficiently correct approximate solutions both far from the resonance and at the resonance conditions. The steady and non-steady resonant vibrations are analyzed by employing the modulation equations of the amplitudes and phases which are yielded by the MSM procedure.
The potential of working hypotheses for deductive exploratory research
Authors: Casula Mattia , Rangarajan Nandhini , Shields Patricia 
Published: December 2020

AbstractWhile hypotheses frame explanatory studies and provide guidance for measurement and statistical tests, deductive, exploratory research does not have a framing device like the hypothesis. To this purpose, this article examines the landscape of deductive, exploratory research and offers the working hypothesis as a flexible, useful framework that can guide and bring coherence across the steps in the research process. The working hypothesis conceptual framework is introduced, placed in a philosophical context, defined, and applied to public administration and comparative public policy. Doing so, this article explains: the philosophical underpinning of exploratory, deductive research; how the working hypothesis informs the methodologies and evidence collection of deductive, explorative research; the nature of micro-conceptual frameworks for deductive exploratory research; and, how the working hypothesis informs data analysis when exploratory research is deductive.

Zhukova reconstructs the ideas of Russian Europeanism, and she evaluates the approaches of Russian thinkers to national cultural history. The author manages to introduce the reader to current discussions about the specifics of the Russian cultural and philosophical “project” and to propose new approaches for the interpretation of the intellectual and literary heritage of Russia. In addition to offering a critical analysis of Zhukova’s volume, the book review presents this thought provoking monograph as a great piece of scholarly work.
Forecasting peak energy demand for smart buildings

Published: December 2020

AbstractPredicting energy consumption in buildings plays an important part in the process of digital transformation of the built environment, and for understanding the potential for energy savings. This also contributes to reducing the impact of climate change, where buildings need to increase their adaptability and resilience while reducing energy consumption and maintain user comfort. The use of Internet of Things devices for monitoring and control of energy consumption in buildings can take into account user preferences, event monitoring and building optimization. Detecting peak energy demand from historical building data can enable users to manage their energy use more efficiently, while also enabling real-time response strategies (including control and actuation) to known or future scenarios. Several statistical, time series, and machine learning techniques are proposed in this work to predict electricity consumption for five different building types, by using peak demand forecasting to achieve energy efficiency. We have used several indigenous and exogenous variables with a view to test different energy forecasting scenarios. The suggested techniques are evaluated for creating predictive models, including linear Regression, dynamic regression, ARIMA time series, exponential smoothing time series, artificial neural network, and deep neural network. We conduct the analysis on an energy consumption dataset of five buildings from 2014 until 2019. Our results show that for a day ahead prediction, the ARIMA model outperforms the other approaches with an accuracy of 98.91% when executed over a 168 h (1 week) of uninterrupted data for five government buildings.

AbstractThe Covid-19 pandemic affected large part of Italy since February 2020; we, therefore, aimed to assess the impact of 2020 SARS-CoV-2 outbreak on telemedicine management of cardiovascular disease (CVD) in Italy. We analyzed data from three telemedicine dispatch centers, one located in Genoa, serving private clients (pharmacies, general practitioners), one in Brescia, serving pharmacies, and one in Bari, serving regional public STEMI network and emergency medical service in Apulia (4 million inhabitants). Demographic data and principal electrocardiogram diagnosis were collected and analyzed. Records from the time interval March 1, 2020 and April 1, 2020 were compared with the corresponding period in 2019. The comparative analysis of data shows a 54% reduction of telemedicine electrocardiogram transmission in Genoa telemedicine center (from 364 to 166), 68% in Brescia (from 5.745 to 1.905), 24% in Bari (from 15.825 to 11.716); relative reduction according to electrocardiogram diagnosis was 38% for acute coronary syndrome, 40% for other acute CVD in Genoa center, 24% for acute coronary syndrome, and 38% for other acute CVD in Bari. Male/female ratio remained substantially unchanged. A dramatic reduction of telemedicine access for CVD was observed during Covid-19 outbreak in March 2020 in Italy. The reduction was substantially consistent for all electrocardiogram findings, ACS, other acute CVD and normal.
Consumers’ preferences regarding energy efficiency: a qualitative analysis based on the household and services sectors in Spain
Authors: de Ayala Amaia , Foudi Sébastien , Solà María del Mar , López-Bernabé Elena , Galarraga Ibon 
Published: December 2020

AbstractInformational failures frequently lead consumers to make non-optimal energy-efficient purchasing decisions. Energy efficiency labels seek to influence consumer behaviour at the point of sale by reducing informational failures regarding energy efficiency. However, several informational and behavioural factors contribute to the energy efficiency gap and could render label-oriented policies useless. The purchasing decision model of Allcott and Greenstone (The Journal of Economic Perspectives, 26, 3–28, 2012) is used here to explore the different factors that influence purchasing decisions and understand (i) the importance of energy consumption compared to other attributes; (ii) how consumers weight energy savings and (iii) what other benefits and costs influence the purchase of energy-efficient goods. The analysis reported here is based on qualitative research methods and is conducted in the household and service sectors (the accommodation sector and private service companies), for appliances, heating and cooling systems and cars in Spain. Results show that (i) there is still an informational gap regarding energy labels and (ii) bounded rationality and end-user behaviour are important limiting factors for the purchase of energy-efficient goods in Spain.
Know-Your-Customer (KYC) Requirements for Initial Coin Offerings
Authors: Ostern Nadine Kathrin , Riedel Johannes 
Published: December 2020

AbstractBlockchain technology is often proposed as an infrastructure for decentralized Know-Your-Customer (KYC) verification, i.e., a process determining whether a customer is eligible for a given transaction. The benefit of using blockchain technology lies in the expected compliance costs reduction for companies by automatically enforcing KYC-requirements, whose results are accessible by multiple financial institutions. While information systems researchers have proposed conceptual models and prototypes of blockchain-based KYC-systems, they do not yet consider severe penalties that are applicable to companies if KYC-requirements are not met. Hence, if the legal requirements for KYC-processes cannot be met, these systems are not applicable. The paper uses an objective-centered design science research approach to develop a blockchain-based KYC-system for the conduct of ICOs that is compliant-by-design. To this end, the authors first identify existing KYC-requirements and define corresponding system design objectives that are used to develop a KYC-system that automatically enforces KYC-regulations, thereby preventing money laundering and other forms of identity fraud. Second, the authors contribute to the literature by providing a blueprint for compliant-by-design blockchain-based KYC-systems, in the paper, integrated into the investment flow of an ICO. Third, the authors propose a KYC-system that is applicable in the real world, by making – due to legal certainty – KYC-processes cost-effective, i.e., the proposed blockchain-based KYC-system expectably reduces compliance costs for customers and financial organizations.

AbstractCoronavirus disease (COVID-19), caused by acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is a worldwide challenge effecting millions of people in more than 210 countries, including the Sultanate of Oman (Oman). Spatiotemporal analysis was adopted to explore the spatial patterns of the spread of COVID-19 during the period from 29th April to 30th June 2020. Our assessment was made using five geospatial techniques within a Geographical Information System (GIS) context, including a weighted mean centre (WMC), standard deviational ellipses, Moran’s I autocorrelation coefficient, Getis-Ord General-G high/low clustering, and Getis-Ord $$G_{i}^{*}$$

The Moran’s I and Z scores were above the 2.25 threshold (a confidence level above 95%), ranging from 2274 cases on 29th April to 40,070 cases on 30th June 2020. The results of $$G_{i}^{*}$$

showed varying rates of infections, with a large spatial variability between the different wilayats (district). The epidemic situation in some wilayats, such as Mutrah, As-Seeb, and Bowsher in the Muscat Governorate, was more severe, with Z score higher than 5, and the current transmission still presents an increasing trend. This study indicated that the directional pattern of COVID-19 cases has moved from northeast to northwest and southwest, with the total impacted region increasing over time. Also, the results indicate that the rate of COVID-19 infections is higher in the most populated areas. The findings of this paper provide a solid basis for future study by investigating the most resolute hotspots in more detail and may help decision-makers identify targeted zones for alleviation plans.
Concern and Externalities Associated with Locating Hemp Production and Processing Facilities
Authors: Campbell Julie H. , Rabinowitz Adam N. , Campbell Benjamin L. 
Published: December 2020

AbstractThe legalization of hemp in the United States (U.S.) has created increased interest from agricultural and non-agricultural entities seeking to establish/expand hemp production and processing. As these entities begin to locate their production and processing operations, there is a potential for nearby residents to have concerns about these efforts. Using an online survey of residents from the southeastern U.S., concern levels and potential externalities associated with hemp production and processing were evaluated. Results show a majority of residents are concerned about hemp production and processing locating nearby with the externalities varying from the potential for illegal activity to environmental concerns.
Widowing the Streets of Troy (Il. 5.642): Notes on the Conceptual Basis of a Unique Metaphor in Homer'sIliad
Authors: Horn Fabian 
Published: December 2020

AbstractThis article argues for an approach based on the cognitive linguistic theory of conceptual metaphors (CMT) by demonstrating its potential for the discussion and interpretation of Homeric metaphors. CMT provides a theoretical framework for analysing metaphors in a conceptual context, and even with unique, i.e. apparently non-formulaic, metaphors in Homeric poetry the possibility of a conceptual basis always needs to be considered for comprehensive study. Even unusual expressions such as the phrasing ofIl. 5.642, χήρωσɛ δ’ ἀγυιάς, where Heracles is said to have ‘widowed the streets’ of Troy can be related to other metaphors (esp. Τροίης ἱɛρὰ κρήδɛμνα inIl. 16.100, where the phrasing is formulaic) drawing on the same conceptualization ofthe city is a woman. This appears to be a contextually specified version of the personification of locations which not only provides the basis for poetic extensions but also has the potential to reflect back on the literal usage of certain salient terms and imbue them with particular, ominous meaning (such as κρήδɛμνον inIl. 22.470).
Finding Direction at the Edge of Law and Life: Islamic Fiqh, Correspondence, and UAE Takāful Insurance Regulation
Authors: Jadalhaq Iyad Mohammad , Russi Luigi 
Published: December 2020

AbstractThe Islamic legal enterprise forms an inherently plural system that can appear puzzling to commentators looking for faithfulness to principle or precedent. When one looks at it, instead, as an ongoing search for correspondence between divine guidance, rooted in the foundational sources of Islam, and the singularity of concrete circumstances, Islamic law is revealed as a practice of discernment against the grain of the particular. This article unfolds this approach to understanding Islamic law by entering the conversation where it is currently most heated, namely in connection with the development of Islamic financial products. A case study of takāful regulation in the United Arab Emirates (UAE) helps substantiate the import of our proposal for attuning to the voice of Islamic jurisprudence (fiqh), in the face of contemporary questions arising from the design of financial products in correspondence with the Sharī’ah.
