A new study to suppress mutual-coupling between waveguide slot array antennas based on metasurface bulkhead for MIMO systems by Alibakhshikenari, Mohammad, Virdee, Bal Singh, Khalily, Mohsen, See, Chan, Abd-Alhameed, Raed, Falcone, Francisco, Limiti, Ernesto

“…The proposed method is should find application in MIMO systems where high isolation between neighbouring radiation elements is required to improve the antenna characteristics, and mimimise array phase errors, which is necessary to enhance the system performance.…”

Mean reversion, long memory and fractional integration in African stock market prices by Anoruo, Emmanuel, Gil-Alana, Luis A.

“…Our results can be summarized as follows: we cannot find evidence of mean reversion in any single market, and evidence of long memory returns (i.e., orders of integration above 1 in the logged stock prices) is obtained in the cases of Egypt and Nigeria, and, in a lesser extent in Tunisia, Morocco and Kenya. …”

Is the consumption-income ratio stationary? Evidence from linear and nonlinear panel unit root tests for OECD and non-OECD countries by Cerrato, Mario, Peretti, Christian de, Stewart, Chris

“…This extends evidence provided in the recent literature to consider both linear and nonlinear adjustment in panel unit root tests, to addresst he issue of cross-sectional dependence, and to substantially expand both time-series and cross sectional dimensions of the data analysed. We find that the majority (65%) of the series are nonstationary with slightly fewer OECD countries’ (61%) series exhibiting a unit root than non-OECD countries (68%).…”

Interest and exchange rate risk and stock returns : a multivariate GARCH-M modelling approach by Beirne, John, Caporale, Guglielmo Maria, Spagnolo, Nicola

“…The econometric framework is a four-variate GARCH-in-mean model, which incorporates long-and short-term interest rates in turn. We find in most cases a positive effect of stock market returns on mean returns in each sector; by contrast, interest rates and exchange rates have a significant effect only in a few cases, respectively negative and without a clear sign pattern. …”

University ownership and information about the entrepreneurial opportunity in commercialisation: a systematic review and realist synthesis of the literature by Kalantaridis, Christos, Merle, Kuttim

“…In addressing this issue we adopt a theory-led realist synthesis approach to the conduct of a systematic literature review. Whilst we find empirical evidence supporting the conclusions of theoretical models, i.e. the strengthening role of technology transfer offices, we also point to their shortcomings. …”

Geometric and homological methods in group theory: constructing small group resolutions by Gill, Olivia Jo

“…Our aim is to construct a free crossed resolution, A* --> G, by way of induction on the degree n, for any semidirect product G = K x H. First we show how to find a set Z1 of generators for the free group A1 and the corresponding unique epimorphism from the free group on those generators to the semidirect product. …”
