Hourly electricity demand forecasting using Fourier analysis with feedback
Authors:
Publisher and Date:(Elsevıer, 2020)Whether it be long-term, like year-ahead, or short-term, such as hour-ahead or day-ahead, forecasting of electricity demand is crucial for the success of deregulated electricity markets. The stochastic nature of the demand for electricity, along with parameters such as temperature, humidity, and work habits, eventually causes deviations from expected demand. In this paper, we propose a feedback-based forecasting methodology in which the hourly prediction by a Fourier series expansion is updated ...

What Can We Estimate From Fatality and Infectious Case Data Using the Susceptible-Infected-Removed (SIR) Model? A Case Study of Covid-19 Pandemic
Authors:
Publisher and Date:(Frontıers Medıa Sa, 2020)The rapidly spreading Covid-19 that affected almost all countries, was first reported at the end of 2019. As a consequence of its highly infectious nature, countries all over the world have imposed extremely strict measures to control its spread. Since the earliest stages of this major pandemic, academics have done a huge amount of research in order to understand the disease, develop medication, vaccines and tests, and model its spread. Among these studies, a great deal of effort has been invested ...

Revisiting the Britain-US-Turkey triangle during the transition from Pax Britannica to Pax Americana (1947-1957)
Authors:
Publisher and Date:(Routledge Journals, Taylor & Francıs Ltd, 2020)This article analyses the triangular relations between Britain, the United States and Turkey in the volatile Middle East and Eastern Mediterranean region at the advent of the Cold War. It examines the political, economic and military strategies that enabled Turkey to adapt to the transitional period from the Pax Britannica to the Pax Americana (1947-1957) in the Middle East and the Eastern Mediterranean. By focusing on this turbulent decade extending from the Truman Doctrine (1947) to the Eisenhower ...

Across dimensions: Two- and three-dimensional phase transitions from the iterative renormalization-group theory of chains
Authors:
Publisher and Date:(2020)Sharp two- and three-dimensional phase transitional magnetization curves are obtained by an iterative renormalization-group coupling of Ising chains, which are solved exactly. The chains by themselves do not have a phase transition or nonzero magnetization, but the method reflects crossover from temperaturelike to fieldlike renormalization-group flows as the mechanism for the higher-dimensional phase transitions. The magnetization of each chain acts, via the interaction constant, as a magnetic ...

The role ofco-regulationof stress in the relationship between perceived partner responsiveness and binge eating: A dyadic analysis
Authors:
Publisher and Date:(Ohn Wıley & Sons Ltd, 2020)The main aim of this study is to investigate whether there are relationships between perceived partner responsiveness (PPR), co-regulation of negative affect between romantic partners and binge eating. Data were collected from 148 opposite-sex romantic partners (18-61 years old) with the mean relationship duration being 8.04 years. Dyadic data were analysed through the actor-partner interdependence model framework. We proposed a model where co-regulation between partners has indirect effects on ...

Holocene climate forcings and lacustrine regime shifts in the Indian summer monsoon realm
Authors:
Publisher and Date:(Wıley, 2020)Extreme climate events have been identified both in meteorological and long-term proxy records from the Indian summer monsoon (ISM) realm. However, the potential of palaeoclimate data for understanding mechanisms triggering climate extremes over long time scales has not been fully exploited. A distinction between proxies indicating climate change, environment, and ecosystem shift is crucial for enabling a comparison with forcing mechanisms (e.g. El-Nino Southern Oscillation). In this study we ...

Metamorphic Leaves
Authors:
Publisher and Date:(Mıt Press, 2020)This article introduces an algorithm influenced by Goethe's concept of metamorphosis capable of generating a wide range of parametric leaf forms. Metamorphosis is defined as alternating stages of expansion and contraction that are observable during the development of flowering plants. This principle is extended toward leaf morphology, where two main developmental trajectories are outlined. By formulating simple two-dimensional geometric rules, the author tests the concept of metamorphosis on ...

Adoption of Mobile Health Apps in Dietetic Practice: Case Study of Diyetkolik
Authors:
Publisher and Date:(Jmır Publıcatıons, Inc, 130 Queens Quay E, 2020)Background: Dietetics mobile health apps provide lifestyle tracking and support on demand. Mobile health has become a new trend for health service providers through which they have been shifting their services from clinical consultations to online apps. These apps usually offer basic features at no cost and charge a premium for advanced features. Although diet apps are now more common and have a larger user base, in general, there is a gap in literature addressing why users intend to use diet apps. ...

Neo-Weberian historical sociology, the English School and differentiated integration in the E
Authors:
Publisher and Date:(Routledge Journals, Taylor & Francıs Ltd, 2020)This article explores the contributions of Neo-Weberian historical sociology of the state and the English School of International Relations theory to our understanding of differentiated integration in the European Union. In doing so, it turns to the English School concept of 'radial empires' to establish differentiation as a structural feature of all centralized entities in international society such as the European Union. It then turns to the concepts of 'sociospatial networks of power' and ...

The ULX source X-3 in NGC 4258: a search for its X-ray and optical properties
Authors:
Publisher and Date:(Oxford Unıv Press, 2020)We present the results of a search for the nature of ultraluminous X-ray source (ULX) X-3 in the nearby galaxy NGC 4258. We use archival data from XMM-Newton, Chandra, NuSTAR, and Hubble Space Telescope (HST) observations. Total X-ray data were analysed to find that the model parameters of the system are indicative of a stellar-mass black hole, similar to 10 M-circle dot, as the central compact object. Furthermore, analyses of the optical data from HST reveal two optical candidates at 90 per cent ...

All the Dark Triad and some of the Big Five traits are visible in the face
Authors:
Publisher and Date:(Pergamon-Elsevıer Scıence Ltd, 2021)Some of the recent studies suggested that people can make accurate inferences about the level of the Big Five and the Dark Triad personality traits in strangers by only looking at their faces. However, later findings provided only partial support and the evidence is mixed regarding which traits can be accurately inferred from faces. In the current research, to provide further evidence on whether the Big Five and the Dark Triad traits are visible in the face, we report three studies, two of which ...

Minimum Length Scheduling for Full Duplex Time-Critical Wireless Powered Communication Networks
Authors:
Publisher and Date:(IEEE, 2020)Radio frequency (RF) energy harvesting is key in attaining perpetual lifetime for time-critical wireless powered communication networks (WPCNs) due to full control on energy transfer, far field region, small and low-cost circuitry. In this paper, we propose a novel minimum length scheduling problem to determine the optimal power control, time allocation and schedule subject to data, energy causality and maximum transmit power constraints in a full-duplex WPCN. We first formulate the problem as a ...

Cultural differences in performance on Eriksen's flanker task
Authors:
Publisher and Date:(Springer, 2020)Eriksen's zoom model of attention implies a trade-off between the breadth and resolution of representations of information. Following this perspective, we used Eriksen's flanker task to investigate culture's influence on attentional allocation and attentional resolution. In Experiment1, the spatial distance of the flankers was varied to test whether people from Eastern cultures (here, Turks) experienced more interference than people from Western cultures (here, Americans) when flankers were further ...

Economic policy uncertainty, stakeholder engagement, and environmental, social, and governance practices: The moderating effect of competition
Authors:
Publisher and Date:(Wiley, 2020)his paper investigates the effect of the economic policy uncertainty (EPU) on corporate environmental, social, and governance practices (ESG), using 6,562 firm-year observations from 15 developed European countries covering the period from 2004 to 2017. The results show that during periods of high uncertainty, firms increase their overall ESG performance, corporate environmental performance, and performance in governance. The relationship is valid for emission, resource use, workforce, management, ...

R&D Activity and Financing Constraints: Evidence from Turkey
Authors:
Publisher and Date:(Savez Ekonomista Vojvodine, 2020)We analyze the relationship between financing constraints and firms' R&D activity using a rich and comprehensive firm-level balance sheet and income statement data set of manufacturing firms in Turkey for the period 1996 to 2013. Using a firm-specific, time-varying financing constraints index, we find that financing constraints have a negative relationship with firms' R&D activity, after controlling for other determinants of R&D such as firm size, capital intensity and export market participation.

Frustrated Potts model: Multiplicity eliminates chaos via reentrance
Authors:
Publisher and Date:(Amer Physical Soc, 2020)The frustrated q-state Potts model is solved exactly on a hierarchical lattice, yielding chaos under rescaling, namely, the signature of a spin-glass phase, as previously seen for the Ising (q = 2) model. However, the ground-state entropy introduced by the (q > 2)-state antiferromagnetic Potts bond induces an escape from chaos as multiplicity q increases. The frustration versus multiplicity phase diagram has a reentrant (as a function of frustration) chaotic phase.

Responses to replica (vs. genuine) touristic experiences
Authors:
Publisher and Date:(Pergamon-Elsevier Science, 2020)A growing trend in tourism is the use of replica experiences. Yet, consumers' responses to replica (vs. genuine) touristic experiences are mostly overlooked in the literature. In this paper, we propose that consumers' perceptions of authenticity of the replica (vs. genuine) touristic experiences mediate their responses to these experiences. We define three theoretically driven factors that influence the authenticity perceptions of consumers-experience characteristics (restricted experience vs. not ...
