Abstract: A stand-alone multi-microgrid (MMG) system can be formed by connecting multiple stand-alone microgrids (MGs). In the stand-alone MMG system where the frequencies of each MG system are different, a back-to-back (BTB) converter can be used for interconnecting the adjacent MG system. The frequency control performance of the MMG system can be improved by designing the suitable controller ...

In this paper, a two-surfaces sliding mode controller (TSSMC) is proposed for the voltage tracking control of a two input DC-DC converter in application of electric vehicles (EVs). The imperialist competitive algorithm (ICA) is used for tuning TSSMC parameters. The proposed controller significantly improves the transient response and disturbance rejection of the two input converters while p...

Although the pivotal role of follicular dendritic cells (FDCs) in humoral immune responses has been demonstrated, little is known at the molecular level of how FDCs contribute to the organogenesis, B cell differentiation, and regulation of T cell functions in the germinal center. By immunizing with FDC-like cells, we have developed a monoclonal antibody (MAb), which stains the germinal centers ...

We present a framework based on spectral graph theory that captures the interplay among network topology, system inertia, and generator and load damping in determining overall power grid behavior and performance. Specifically, we show that the impact of network topology on a power system can be quantified through the network Laplacian eigenvalues, and such eigenvalues determine the grid robustn...

The Droop quota is traditionally rounded up to the next integer. It has been pointed out by Lundell and Hill that this can have negative consequences. We give two further examples of such consequences, showing that rounding the Droop quota can cause violations of monotonicity and proportionality. This supports the conclusion by Lundell and Hill that it is better to use the exact Droop quota wit...

INTRODUCTION Recently, a novel protein, follicular dendritic cell secreted protein (FDC-SP), has been identified in human periodontal ligament (PDL) tissue and a biomolecular study suggested that the expression of FDC-SP might be associated with the expression of the PDL phenotype. The purpose of this study was to test the effect of FDC-SP on the proliferation and phenotype of PDL cells. MATE...

The decarboxylation of antimicrobial aromatic acids such as phenylacrylic acid (cinnamic acid) and ferulic acid by yeast requires two enzymes described as phenylacrylic acid decarboxylase (PAD1) and ferulic acid decarboxylase (FDC). These enzymes are of interest for various biotechnological applications, such as the production of chemical feedstocks from lignin under mild conditions. However, t...
