For ultra-dense networks, user-centric architecture is regarded as a promising candidate to offer mobile users better quality of service. One the main challenges exploring efficient scheme for user association in network. In this letter, we study dynamic (UCA) problem millimeter wave (mmWave) networks provide reliable connectivity and high achievable data rate. We consider time-varying network ...

There is a layer of the unconsolidated confined aquifer (UCA) made non-cemented sand and grit on bed Quaternary thick topsoil in many coal mines east north China. Existing bedrock measures, it poses serious threat to mine safety. Worse, caused supports crushing water inrush disasters (SCWIDs) resulted significant economic losses. Aiming at above problems, this paper adopts simulation experiment...

OBJECTIVE To describe the biochemical effects of an over-supplementation of vitamin D3 in two patients with primary hyperparathyroidism (PHPT). DESIGN Two patients (A and B) with PHPT took erroneously 2,400,000 U (300,000 U/day for 8 days) and 4,500,000 U (300,000 U/day for 15 days) of cholecalciferol, respectively. They were followed for 4 months and ionized calcium, creatinine, PTH, 25 hydr...

AIMS AND OBJECTIVES To investigate the expression of CD10 and osteopontin in dentigerous cyst and ameloblastoma and to correlate their expression with neoplastic potentiality of dentigerous cyst and local invasion and risk of local recurrence in ameloblastoma. METHODS CD10 and osteopontin expression was studied by means of immunohistochemistry in 9 cases of dentigerous cysts (DC) and 17 cases...

The structural gene (fdhF) for the 80-kDa selenopolypeptide of formate dehydrogenase (formate:benzyl viologen oxidoreductase, EC 1.2.--.--) from Escherichia coli contains an in-frame UGA codon at amino acid position 140 that is translated. Translation of gene fusions between N-terminal parts of fdhF with lacZ depends on the availability of selenium in the medium when the hybrid gene contains th...

Many species reproduce when conditions are most favorable for the survival of young. Numerous intertidal fish and invertebrates release eggs or larvae during semilunar, large amplitude, nocturnal tides when these early life stages are best able to escape predation by fish that feed near the shore during the day. Remarkably, some species, including the fiddler crabs Uca terpsichores and Uca deic...

MHC class I proteins mediate a variety of functions in antiviral defense. In humans and mice, three MHC class I loci each contribute one or two alleles and each can present a wide variety of peptide Ags. In contrast, many lower vertebrates appear to use a single MHC class I locus. Previously we showed that a single locus was predominantly expressed in the mallard duck (Anas platyrhynchos) and t...

Here, we described a novel strategy for the production of itaconic acid in Escherichia coli by self-assembly of aconitase (ACO) and cis-aconitate decarboxylase (CAD) existing in the metabolic pathway of itaconic acid via the protein-peptide interactions of PDZ domain and PDZ ligand. Co-expression of ACO and CAD in E. coli (uCA) resulted in low levels of itaconate (117.25 mg/L) after 48 h fermen...
