High Order Riesz Transforms and Mean Value Formula for Generalized Translate Operator

In this paper, the mean value formula depends on the Bessel generalized shift operator corresponding to the solutions of the boundary value problem related to the Bessel operator are studied. In addition to, Riesz Bessel transforms related to the Bessel operators are studied. Since Bessel generalized shift operator is translation operator corresponding to the Bessel operator, we construct a family of RBxj by using Bessel generalized shift operator. Finally, we analysis weighted inequalities involving Riesz Bessel transforms

Complementarities and the Existence of Strong Berge Equilibrium

Cataloged from PDF version of article.This paper studies the existence and the order structure of strong Berge equilibrium, a refinement of Nash equilibrium, for games with strategic complementarities a la strong Berge. It is shown that the equilibrium set is a nonempty complete lattice. Moreover, we provide a monotone comparative statics result such that the greatest and the lowest equilibria are increasing

Modelling the impact of earthquake activity on real estate values: a multi-level approach

Purpose – This paper seeks to look at the impact of recent earthquake activity on house prices and their spatial distribution in the Istanbul housing market. Design/Methodology/Approach – The paper employs a multi-level approach within an event study framework to model changes in the pattern of house prices in Istanbul. The model allows us to isolate the effects of earthquake risk and explore the differential impact in different submarkets in two study periods - one before (2007) and one after (2012) recent earthquake activity in the Van region, which although in Eastern Turkey, served to alter the perceptions of risk through the wider geographic region. Findings – The analysis shows that their are variations in the size of price discounts in submarkets resulting from the differential influence of recent earthquake activity on perceived risk of damage. The model results show that the spatial impacts of these changes are not transmitted evenly across the study area. Rather it is clear that submarkets at the cheaper end of the market have proportionately larger negative impacts on real estate values. Practical implications – The methods introduced in this study can be used by real estate agents, valuers, and insurance companies to help them more accurately assess the likely impacts of changes in the perceived risk of earthquake activity (or other environmental events such as flooding) on the formation of house prices in different market segments. Originality/value – The paper represents an attempt to develop a novel extension of the standard use of hedonic models in event studies to investigate the impact of natural disasters on real estate values. The value of the approach is that it is able to better capture the granularity of the spatial effects of environmental events than the standard approach

A minimally altruistic refinement of Nash equilibrium

Cataloged from PDF version of article.We introduce a minimal notion of altruism and use it to refine Nash equilibria in normal form games. We provide three independent existence proofs, relate minimally altruistic Nash equilibrium to other equilibrium concepts, conduct an in-depth sensitivity analysis, and provide examples where minimally altruistic Nash equilibrium leads to improved predictions.

General Complementarities on Complete Partial Orders

Cataloged from PDF version of article.This paper proves the existence of a Nash equilibrium for extended (semi-) uniform g-modular games, i.e., non-cooperative games where the strategy space is a complete partially ordered set, and the best reply correspondence satisfies certain monotonicity requirements

Examination of the Compatibility of the Questions Used by Social Studies Teachers in the Class with the Program Achievements According to the SOLO Taxonomy

The purpose of this study is to examine the compatibility of the questions used by the social studies branch teachers in the level of 6th and 7th grade with the achievements included in the teaching program. Structure of observed learning outcome (SOLO) taxonomy, which was presented by Biggs and Colis (1982) as an alternative to Bloom’s cognitive domain classification, is used for this examination. The research has been complied with the ‘case study’ qualitative research pattern, and observation and document analysis technique was used. Four teachers were observed at the level of sixth grade and three teachers were observed at the level of seventh grade. At the level of sixth grade, one teacher was observed within the first unit, the others in the second unit; and at the level of seventh grade, three teachers were observed within the second unit. It was discovered at the end of the research that questions asked by the teachers in the class complied with the uni-structural and multi-structural levels although most of the relevant achievements given in the program corresponded to the relational structure level according to the SOLO taxonomy. Results of this study show that the SOLO taxonomy can be used effectively both in the teaching programs and during the learning-teaching process

Pion wave functions from holographic QCD and the role of infrared renormalons in photon-photon collisions

In this article, we calculate the contribution of the higher-twist Feynman diagrams to the large-$p_T$ inclusive single pion production cross section in photon-photon collisions in case of the running coupling and frozen coupling approaches within holographic QCD. We compare the resummed higher-twist cross sections with the ones obtained in the framework of the frozen coupling approach and leading-twist cross section. Also, we show that in the context of frozen coupling approach a higher-twist contribution to the photon-photon collisions cross section is normalized in terms of the pion electromagnetic form factor.Comment: 21 pages, 15 figures. arXiv admin note: text overlap with arXiv:0709.2072 by other author

Modular Orthopaedic Tissue Engineering With Implantable Microcarriers and Canine Adipose-Derived Mesenchymal Stromal Cells

Mesenchymal stromal cells (MSC) hold significant potential for tissue engineering applications. Modular tissue engineering involves the use of cellularized “building blocks” that can be assembled via a bottom-up approach into larger tissue-like constructs. This approach emulates more closely the complexity associated hierarchical tissues compared with conventional top-down tissue engineering strategies. The current study describes the combination of biodegradable porous poly(DL-lactide-co-glycolide) (PLGA) TIPS microcarriers with canine adipose-derived MSC (cAdMSC) for use as implantable conformable building blocks in modular tissue engineering applications. Optimal conditions were identified for the attachment and proliferation of cAdMSC on the surface of the microcarriers. Culture of the cellularized microcarriers for 21 days in transwell insert plates under conditions used to induce either chondrogenic or osteogenic differentiation resulted in self-assembly of solid 3D tissue constructs. The tissue constructs exhibited phenotypic characteristics indicative of successful osteogenic or chondrogenic differentiation, as well as viscoelastic mechanical properties. This strategy paves the way to create in situ tissue engineered constructs via modular tissue engineering for therapeutic applications

Origin of Native Driving Force in Protein Folding

We derive an expression with four adjustable parameters that reproduces well the 20x20 Miyazawa-Jernigan potential matrix extracted from known protein structures. The numerical values of the parameters can be approximately computed from the surface tension of water, water-screened dipole interactions between residues and water and among residues, and average exposures of residues in folded proteins.Comment: LaTeX file, Postscript file; 4 pages, 1 figure (mij.eps), 2 table

Near-field Localization with a Reconfigurable Intelligent Surface Acting as Lens

Exploiting wavefront curvature enables localization with limited infrastructure and hardware complexity. With the introduction of reconfigurable intelligent surfaces (RISs), new opportunities arise, in particular when the RIS is functioning as a lens receiver. We investigate the localization of a transmitter using a RIS-based lens in close proximity to a single receive antenna element attached to reception radio frequency chain. We perform a Fisher information analysis, evaluate the impact of different lens configurations, and propose a two-stage localization algorithm. Our results indicate that positional beamforming can lead to better performance when a priori location information is available, while random beamforming is preferred when a priori information is lacking. Our simulation results for a moderate size lens operating at 28 GHz showcased that decimeter-level accuracy can be attained within 3 meters to the lens
