The Fidelity of Measurement-Based Quantum Computation under a Boson Environment
We investigate the fidelity of the measurement-based quantum computation
(MBQC) when it is coupled with boson environment, by measuring cluster state
fidelity and gate fidelity. Two different schemes of cluster state preparation
are studied. In the Controlled-Z (CZ) creation scheme, cluster states are
prepared by entangling all qubits in state with CZ gates on all
neighboring sites. The fidelity shows an oscillation pattern over time
evolution. The influence of environment temperature is evaluated, and
suggestions are given to enhance the performance of MBQC realized in this way.
In the Hamiltonian creation scheme, cluster states are made by cooling a system
with cluster Hamiltonians, of which ground states are cluster states. The
fidelity sudden drop phenomenon is discovered. When the coupling is below a
threshold, MBQC systems are highly robust against the noise. Our main
environment model is the one with a single collective bosonic mode.Comment: 13 pages, 16 figure
Indoor Environmental Quality of Residential Elderly Care Facilities in Northeast China.
The indoor environmental quality is based on the indoor environmental performance of buildings, such as air temperature, lighting, and acoustics. These parameters have a specific impact on users' health and experience. This study explores the relationship between the indoor environment of residential elderly care facilities in cold regions and the sensitivity of the elderly to these facilities with the aim of improving the elderly care environment. This study measured the acoustic, lighting, and thermal environment in four residential elderly care facilities in Northeast China in spring, summer, autumn, and winter through a participant survey. In the residential elderly care facilities surveyed in this study, brightness and illuminance show a nonlinear relationship with lighting evaluation. With an increase in brightness and illuminance, the satisfaction of the lighting environment in different seasons first increases and then decreases. The relative humidity of the different types of rooms varies greatly in spring and less in winter. The average air quality score of the bedroom is higher than that of the activity room. The correlation between odor assessment and overall indoor environmental quality is very poor. The results of the questionnaire survey indicate that the participants were satisfied with the facilities' overall indoor environmental quality. This quality is affected by physical, environmental, and demographic factors. This study provides a reference for the design of other residential elderly care facilities

Dataset for the proteomic and transcriptomic analyses of perivitelline fluid proteins in Pomacea snail eggs
This article describes how the proteomic and transcriptomic data were produced during a study of the reproductive proteins of Pomacea maculata, an aquatic apple snail laying colorful aerial eggs, and provides public access to the data. The data are related to a research article titled ?An integrated proteomic and transcriptomic analysis of perivitelline fluid proteins in a freshwater gastropod laying aerial eggs? (Mu et al., 2017) [1]. RNA was extracted from the albumen gland and other tissues and sequenced on an Illumina Hiseq. 2000. The assembled transcriptome was translated into protein sequences and then used for protein identification. Proteins from the perivitelline fluid of P. maculata were separated in SDS-PAGE and analyzed by LTQ-Orbitrap Elite coupled to an Easy-nLC. The translated transcriptome data are provided in this article. Proteomic data (.raw file format) are available via ProteomeXchange with the identifier PXD006718.Fil: Mu, Huawei.

Banach spaces not antiproximinal in their second dual
AbstractWe prove that (l1,¦·¦) is not antiproximinal in (l1,¦·¦)∗∗, where ¦·¦ is the norm constructed in [1]. This fact shows that Davidson's equivalent norm fails to deliver on his promise
