Uncertain Consumption Preference under Mortality Salience
Based on the relevant theoretical research on mortality salience and general self-efficacy, this paper tests the impact of mortality salience on uncertain consumption intention through experiments. It is found that mortality salience increases consumers’ preference to choose uncertain probabilistic promotion methods, but decreases individuals’ evaluation of new products. During the process above, the moderating effect of general self-efficacy was tested. Based on the results, this study provides specific suggestions on the marketing and product strategies in the context of mortality salience
Improving the security of multiparty quantum secret sharing against Trojan horse attack
We analyzed the security of the multiparty quantum secret sharing (MQSS)
protocol recently proposed by Zhang, Li and Man [Phys. Rev. A \textbf{71},
044301 (2005)] and found that this protocol is secure for any other
eavesdropper except for the agent Bob who prepares the quantum signals as he
can attack the quantum communication with a Trojan horse. That is, Bob replaces
the single-photon signal with a multi-photon one and the other agent Charlie
cannot find this cheating as she does not measure the photons before they runs
back from the boss Alice, which reveals that this MQSS protocol is not secure
for Bob. Finally, we present a possible improvement of the MQSS protocol
security with two single-photon measurements and six unitary operations.Comment: 4 pages, 2 figures; The revised version of the paper published in

New universal gates for topological quantum computation with Fibonacci- composite Majorana edge modes on topological superconductor multilayers
We propose a new design of universal topological quantum computer device
through a hybrid of the 1-, 2- and 7-layers of chiral topological
superconductor (TSC) thin films. Based on the coset
construction, strongly correlated Majorana fermion edge modes on the 7-layers
of TSC are factorized into the composite of the Fibonacci -anyon
and -anyon modes in the tricritical Ising model. Furthermore, the
deconfinement of and via the interacting potential gives
the braiding of either or . Topological phase gates are
assembled by the braidings. With these topological phase gates, we find a set
of fully topological universal gates for the composite
Majorana-Ising-type quantum computation. Because the Hilbert space still
possesses a tensor product structure of quibts and is characterized by the
fermion parities, encoding quantum information in this machine is more
efficient and substantial than that with Fibonacci anyons. The computation
results is easier to be read out by electric signals, so are the initial data
inputted.Comment: 6 pages, 3 figues, revised versio
Impacts of operating conditions on specific cake resistance in dead-end microfiltration process
In the present work, the fouling behavior and the corresponding specific cake resistance of polyethersulfone microfiltration membrane fouled by using different solutions (bovine serum albumin solution, sodium alginate solution, humic acid and activated sludge suspension) under different operating conditions, transmembrane pressure (TMP), concentration (C), stirred speed (ω) and temperature (T) were systematically investigated. The ensuing results showed that the proposed equation can be used to accurately calculate instantaneous specific cake resistance (α). The average specific cake resistance increased with increasing operating pressure, concentration, and stirred speed, while it decreased with increasing operating temperature. The average specific cake resistance of sodium alginate (SA) was larger and the sequence was SA>HA>BSA>AS
