Privacy has received increasing concerns in publication of datasets that contain sensitive information. Preventing privacy disclosure and providing useful information to legitimate users for data mining are conflicting goals. Generalization randomized response methods were proposed database community tackle this problem. However, both them have postulated the same prior belief all transactions, which might be wrong modeling lead breach. Besides, generalization usually require a controlling...

We offer theoretical explanations for some recent observations in numerical simulations of quantum random walks (QRWs). Specifically, the case a QRW on line with one particle (walker) and two entangled coins, we explain phenomenon, called ``localization,'' whereby probability distribution walker's position is seen to exhibit persistent major ``spike'' (or ``peak'') at initial other minor spikes which drift infinity either direction. Another interesting finding connection QRWs this sort...

In a quantum Markov chain, the temporal succession of states is modeled by repeated action “bistochastic operation” on density matrix system. Based this conceptual framework, we derive some new results concerning evolution system, including its long‐term behavior. Among our findings fact that Cesàro limit any chain always exists and equals orthogonal projection initial state upon eigenspace unit eigenvalue bistochastic operation. Moreover, if only circle, then converges in conventional sense...

Consider a discrete-time quantum walk on the $N$-cycle subject to decoherence both coin and position degrees of freedom. By examining evolution density matrix system, we derive some new conclusions about asymptotic behavior system. When $N$ is odd, system tends, in long run, maximally mixed state, independent initial state. even, although not necessarily asymptotically stationary, this case too an explicit formulation obtained dynamics Moreover, approach enables us specify limiting mutual...

For a discrete time quantum walk (QW) on the $N$-cycle, allowing for decoherence coin, we derive number of new results, including an explicit formula position probability distribution. QW this type, show that mixing behavior tends, in long-run, to uniform distribution, regardless initial state system and irrespective parity nodes $N$. These results confirm findings previous authors who arrived at similar conclusions through extensive numerical simulations. In particular, infer...

Abstract: Cardiovascular diseases (CVDs) are leading causes of death in the world, owing to noticeable incidence and mortality. Traditional Chinese Medicine (TCM) SINI Decoction (SND) is used prevent treat CVDs, which has attracted extensive attention for its moderate little side effects. However, involved molecular mechanisms exceedingly complicated remain unclear. Systems pharmacology, as a novel approach that integrates systems biology pharmacology plays significant role investigating...

Similar to other higher plants, cpDNA have a large single copy (LSC) region 90 059 small copy(SSC) 18 412 bp, separated by pair inverted repeats (IRa IRb) 26 033 bp. There are 113 genes cpDNA, including 80 protein-coding genes, 4 ribosomal RNA (4 rRNA species), 36...

Fresh walnut is obtaining high attention due to its pleasant taste and health benefits. This study aimed evaluate the influence of storage temperatures (0 °C -20 °C) on kernel quality, total phenols, antioxidant enzyme activities walnuts in three forms (fresh kernels, with green husk, shell). For a short within 3 months at 0 °C, results revealed that husk provided better quality resulting from lower acid value peroxide value, together higher phenol content activity, compared other walnuts....

Poly(N-isopropylacrylamide) (PNIPAM) microgels with a unique thermosensitive swelling and deswelling behavior in water may be capable of sensing the frictional heat sliding interfaces altering performance water-lubricated contacts accordingly. However, rheological properties PNIPAM formation mechanism tribofilms at interface during friction are currently unclear.

We analyze the probability distributions of quantum walks induced from Markov chains by Szegedy (2004). The first part this paper is devoted to finite state chains. It shown that distribution on states underlying chain always convergent in Cesaro sense. In particular, we deduce limiting uniform if transition matrix symmetric. case a non-symmetric chain, exemplify walk not necessarily identical with stationary irreducible chain. scheme can be extended infinite (random walks). second part,...

As a type of promising lubricating additive, carbon nanomaterials can realize ultralow friction with diamond-like films in water. However, the long-term dispersion stability their aqueous solution remains challenge. Herein, we found that poly(N-isopropylacrylamide) (PNIPAM) microgel, which has been extensively used nanodrug delivery, considerably improve graphene oxide and hydroxylated multiwalled nanotubes solutions, while achieving an coefficient 0.02. On basis structural...

The are shown be satisfied by both Hadamard Grover two-dimensional half-spaces. For case, we show that critical exponent hitting distribution 1 lattice spacing tends zero,...

Based on analyzing the advantages and disadvantages of existing multi-class support vector machines, we construct an improved machines based binary tree structure, adopting a new metrics to determine classification order which determines each sub-classifier its location, synthesizes mixed degree distance between classes. Then do measuring experiment using identifies five major P2P IPTV applications, results show that our method is better than one-against-all one-against-one method.

In this paper, we consider a discrete-time quantum walk on the N -cycle governed by condition that at every time step of walk, option persists, with probability p , exercising projective measurement coin degree freedom. For bipartite system kind, prove von Neumann entropy total density operator converges to its maximum value. Thus, when influenced decoherence, mutual information between two subsystems corresponding space and walker must eventually diminish zero. Put plainly, any level...

For a discrete two-state quantum walk (QW) on the half-line with general condition at boundary, we formulate and prove weak limit theorem describing terminal behavior of its transition probabilities. In this context, localization is possible even for predicated assumption homogeneity. Hadamard half-line, shown to be independent initial coin state exhibit no localization.
