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 ...

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 ...

Energy efficient robust scheduling of periodic sensor packets for discrete rate based wireless networked control systems
Authors:
Publisher and Date:(Elsevier, 2020)Wireless networked control systems (WNCSs) require the design of a robust scheduling algorithm that meets the stringent timing and reliability requirements of control systems, despite the limited battery resources of sensor nodes and adverse properties of wireless communication for delay and packet errors. In this article, we propose a robust delay and energy constrained scheduling algorithm based on the exploitation of the mostly pre-known periodic data generation nature of sensor nodes in control ...

Homology modeling andin silicodesign of novel and potential dual-acting inhibitors of human histone deacetylases HDAC5 and HDAC9 isozymes
Authors:
Publisher and Date:(2020)Histone deacetylases (HDACs) are a group of enzymes that have prominent and crucial effect on various biological systems, mainly by their suppressive effect on transcription. Searching for inhibitors targeting their respective isoforms without affecting other targets is greatly needed. Some histone deacetylases have no crystal structures, such as HDAC5 and HDAC9. Lacking proper and suitable crystal structure is obstructing the designing of appropriate isoform selective inhibitors. Here in this ...

Rediscovering Goethe's Concept of Polarity: A New Direction For Architectural Morphogenesis
Authors:
Publisher and Date:(Middle East Technical University, 2020)This paper will introduce Goethe's concept of polarity to discuss its theoretical and computational implications on natural and architectural morphogenesis (1). Polarity, as a dualist principle, is found in most of Goethe's body of works, particularly in his treatise on colour and botanical writings. This concept is explored from a morphogenetic perspective to reconsider Goethe's engagement with natural sciences during Enlightenment where he transfers his ideas on form and growth to architecture. ...

Distinctive communication networks in inactive states of beta(2)-adrenergic receptor: Mutual information and entropy transfer analysis
Authors:
Publisher and Date:(Wiley, 2020)Mutual information and entropy transfer analysis employed on two inactive states of human beta-2 adrenergic receptor (beta(2)-AR) unraveled distinct communication pathways. Previously, a so-called "highly" inactive state of the receptor was observed during 1.5 microsecond long molecular dynamics simulation where the largest intracellular loop (ICL3) was swiftly packed onto the G-protein binding cavity, becoming entirely inaccessible. Mutual information quantifying the degree of correspondence ...
