Dually modified regular maize starch (RMS) and high-amylose (HAMS) were successfully prepared by first acid hydrolysis subsequently hydroxypropylation. The effects of time (0–24 h) propylene oxide (PO) content (10–30%) on the structure physicochemical properties investigated. molar substitution (MS) HAMS samples (up to 0.163) was generally higher than that RMS 0.149), suggesting reactivity amyl...

Various Markov chain Monte Carlo (MCMC) methods are studied to improve upon random walk Metropolis sampling, for simulation from complex distributions. Examples include Metropolis-adjusted Langevin algorithms, Hamiltonian Carlo, and other algorithms related underdamped dynamics. We propose a broad class of irreversible sampling called Hamiltonian-assisted (HAMS), develop two specific with appro...

The data center network is increasingly a cost, reliability and performance bottleneck for cloud computing. Although multi-tree topologies can provide scalable bandwidth and traditional routing algorithms can provide eventual fault tolerance, we argue that recovery speed can be dramatically improved through the co-design of the network topology, routing algorithm and failure detector. We create...

One of the most challenging problems related to operation smart microgrids is optimal home energy management scheme with multiple and conflicting objectives. Moreover, there a noticeable increase in homes equipped renewable sources (RESs), where coordination loads generation can achieve extra savings minimize peak loads. In this paper, solar-powered designed an affordable secure manner, allowin...

1 0 2 0 1 1 (a) Suppose a2 = (1, 2, 2) , a3 = (−2, 0, 1) , a4 = (0, 4, 5) , a5 = (0, 1, 1) . Compute the ranks of A and B. Explain why B can not be obtained from A by a finite number of elementary row operations. Solution: The first 3 columns of B are independent, so its column space has dimension 3, thus rank(B)=3. The second, third and fifth column of A are independent, so its column space ha...

We previously demonstrated that noncytolytic butano! extraction of B16 melanoma cells can increase the number of experimental lung métastases,and that brief incubation of the extracted cells with the extracted moieties reduces metastatic phenotype. This study examined the possibility that the extracted components are endogenous inhibitors of tumor cell surface-associated, degradative enzymes. ...
