Multi-energy microgrid (MEMG) has the potential to improve energy utilization efficiency. However, uncertainty caused by distributed renewable resources brings an urgent need for multi-energy co-optimization ensure secure operation. This paper focuses on distributionally robust management problem MEMG. Various flexible in different sectors are utilized mitigation, then, a data-driven Wasserstei...

One-counter automata (OCA) are pushdown automata which operate only on a unary stack alphabet. We study the computational complexity of model checking computation tree logic (CTL) on transition systems induced by one-counter automata. A PSPACE upper bound is inherited from the modal μ-calculus for this problem proven by Serre. First, we analyze the periodic behaviour of CTL over OCA and derive ...

BACKGROUND Osteochondritis dissecans (OCD) of the knee can be difficult to treat. Cartilage restoration techniques are often indicated when the lesion or fragment cannot be salvaged and the patient remains symptomatic. Fresh osteochondral allograft (OCA) transplantation can restore both bone and cartilage defects characteristic of OCD. HYPOTHESIS We hypothesized that osteochondral allograftin...

Monomethoxy poly(ethylene glycol)-b-poly(Tyr(alkynyl)-OCA), a biodegradable amphiphilic block copolymer, was synthesized by means of ring-opening polymerization of 5-(4-(prop-2-yn-1-yloxy)benzyl)-1,3-dioxolane-2,4-dione (Tyr(alkynyl)-OCA) and used to prepare core cross-linked polyester micelles via click chemistry. Core cross-linking not only improved the structural stability of the micelles bu...

En el presente artículo se realiza un análisis de la evolución división poderes en constitucionalismo mexicano hasta consagración los llamados «órganos constitucionales autónomos» (OCA). Se analiza origen y concepto OCA las imprecisiones definitorias del préstamo conceptual doctrina constitucional mexicana » española. Finalmente, propone una noción propia órganos autónomos que caracterizándolos...

This paper suggests that there should be a realignment of the current Eurozone. There has been research to argue that the Eurozone does not fit the Optimum Currency Area (OCA) criteria. This might be a contributing factor to the current economic crisis in Europe. I propose, based on results from k-means data clustering, that the Eurozone be divided into three separate regions under the European...

This paper describes practices for multi-level modeling by only using existing modeling frameworks that comply Meta-Object Facility (MOF). We design modeling patterns for achieving the multi-level modeling methodologies on Eclipse Modeling Framework, and implement the dataflow model by applying the patterns. Moreover, we attempt to compare the patterns regarding the facilitation of developing b...

We used suppression subtractive hybridization (SSH) and oligonucleotide microarray to differentiate expression profiles of metastasis-related genes and to evaluate their clinical significance in patients with invasive oral cancer (OCa). Overexpression of the specific genes was confirmed by reverse transcription-PCR (RT-PCR). Cells expressing the gene were identified by immunohistochemistry in p...

Tyrosinase serves as a key enzyme in the synthesis of melanin. In humans mutations in the TYR gene are associated with type 1 oculocutaneous albinism (OCA1) that leads to reduced or absent pigmentation of skin, hair and eye. Various mutations causing OCA in man, mouse, rabbit and cattle have been identified throughout the Tyrosinase gene including nonsense, missense, frameshift and splice site ...
