End of poverty, the number one Sustainable Development Goal, focuses on ending all kinds of poverty all over the world. The elimination of all forms of poverty continues to be the biggest problem facing humanity today. The most important problems that have been encountered since the beginning of the energy use are the increasing risk of deterioration of energy supply, energy production and energy poverty. The problem of energy poverty among them is widely mentioned in the literature. In general, ...

Let (X,d) be a finite metric space with elements Pi, i=1,…,n and with distances dij≔d(Pi,Pj) for i,j=1,…,n. The “Gromov product” Δijk, is defined as [Formula presented]. (X,d) is called Δ-generic, if, for each fixed i, the set of Gromov products Δijk has a unique smallest element, Δijiki. The Gromov product structure on a Δ-generic finite metric space (X,d) is the map that assigns the edge Ejiki to Pi. A finite metric space is called “quadrangle generic”, if for all 4-point subsets {Pi,Pj,Pk,Pl}, ...

This study aims to establish actionable guidelines and provide strategic insights as a means of increasing the social media effectiveness of consumer brands. Post-related factors in addition to the contextual and temporal factors influencing consumer engagement (i.e., reposting, commenting on or liking posts), as an indicator of social media effectiveness, are considered in detail in the research model. Moreover, the model considers differences between industries as well as social media platforms. ...

This article examines whether differences in banking market structures across countries influence the local stock market resilience to the COVID-19 pandemic. Using a sample of 66 countries for the period January 2020 to July 2020, our findings demonstrate that countries with more concentrated banking systems, with a higher presence of foreign banks, and a higher share of Islamic banks are more resilient to the pandemic. Considering the banking regulatory differences between countries, we observe ...

Thirty compounds having 1-[2-(5-substituted-2-benzoxazolinone-3-yl) acetyl]-3,5-disubstitutedphenyl-2-pyrazoline structure and nine compounds having N'-(1,3-disubstitutedphenylallylidene)-2-(5-substituted- 2-benzoxazolinone-3-yl)-acetohydrazide skeleton were synthesized and evaluated as monoamine oxidase (MAO) inhibitors. All of the compounds exhibited selective MAO-A inhibitor activity in the nanomolar or low micromolar range. The results of the molecular docking for hydrazone derivatives supported ...

In this paper, a new channel estimation and equalization algorithm for underwater acoustic (UWA) communications is presented. The proposed algorithm is developed to meet the requirements of underwater time-varying sparse channels that undergo Rayleigh fading. In addition, the algorithm takes into consideration a path-based channel model which describes each received path with significant power by an attenuation factor, a Doppler scale, and a delay. Transmit diversity enabled by Alamouti space-frequency ...

It is well-known that time-varying channels can provide time diversity and improve error rate performance compared to time-invariant fading channels. However, exploiting time diversity requires very accurate channel estimates at the receiver. In order to reduce the number of unknown channel coefficients while estimating the time-varying channel, basis expansion models can be used along with long transmission frames that contain multiple orthogonal frequency division multiplexing (OFDM) symbols ...

In recent years, self-reported happiness and fuel poverty have both become hotly-debated topics in the literature. Since both of them affect people's quality of life, they are certainly worth serious consideration. Therefore, this paper aims to conduct a household-level analysis on the association between happiness and fuel poverty taking advantage of other housing characteristics. We used ordered logit model utilizing Turkish Statistical Institute (TURKSTAT)'s 2014-2018 Life Satisfaction Survey ...

Objectives Because more attractive women may be better able to attract and/or retain masculine mates, many researchers have proposed that women who consider themselves to be more physically attractive will show stronger preferences for men displaying masculine facial characteristics. Empirical evidence for this putative association between women's self-rated attractiveness and preference for facial masculinity has come almost entirely from studies of Western women. Thus, we investigated whether ...

The vertical collaborative clustering aims to unravel the hidden structure of data (similarity) among different sites, which will help data owners to make a smart decision without sharing actual data. For example, various hospitals located in different regions want to investigate the structure of common disease among people of different populations to identify latent causes without sharing actual data with other hospitals. Similarly, a chain of regional educational institutions wants to evaluate ...
