Energy-intensive manufacturers have two main options for improving their energy efficiency: design and implement energy efficiency projects on their own (we call this self saving), or enter into energy performance contracts (EPCs), which mainly include shared savings and guaranteed savings. In this paper, we will discuss an energy-intensive manufacturer facing self saving and shared savings options and how this manufacturer chooses the optimal energy saving mode under non-coordination and coordination scenarios. We first formulate several mathematical models of the two types of energy-saving modes based on the assumption of exogenous unit savings (EX). We show that when the unit energy-saving benefit from shared savings is greater than the unit energy-saving benefit from self saving, the manufacturer prefers shared savings under the non-coordination scenario; otherwise, the manufacturer prefers self saving. Furthermore, we find that the bargaining power of the manufacturer is also a key factor in addition to the difference of unit energy-saving benefits under the coordination scenario. Interestingly, sometimes the bargaining power of the manufacturer has no impact on the optimal choice of energy saving modes. Finally, the basic model is extended to endogenization of unit savings (EN), and we show that the optimal choices of energy saving modes are completely different from the basic model. © 2017 Elsevier Ltd

The recent success of emerging wireless sensor networks technology has encouraged researchers to develop new energy-efficient duty cycle design algorithm in this field. The energy-efficient duty cycle design problem is a typical NP-hard combinatorial optimization problem. In this paper, we investigate an improved elite immune evolutionary algorithm (IEIEA) strategy to optimize energy-efficient duty cycle design scheme and monitored area jointly to enhance the network lifetimes. Simulation results show that the network lifetime of the proposed IEIEA method increased compared to the other two methods, which means that the proposed method improves the full coverage constraints. © 2017 Jie Zhou.

This article presents an efficient integrated approach on designing a non-blocking supervisor for the most general classes of Petri nets, called G-systems that allow multiple resource acquisitions. This work mainly focuses on developing a deadlock prevention policy with a polynomial computational complexity. First, an extraction algorithm of liveness requirement constraints is presented according to the concept of resource partial orders. By considering the different resource requirements of various processes, monitors are added for the uncontrolled G-system on the basis of those precise linear inequality constraints. Afterward, we explore an iterative control policy by utilizing the traditional mathematical programming method, which can ensure the liveness of the resultant controlled system. Comparing with the existing deadlock control policies reported in the literature, the proposed method can achieve a non-blocking controlled G-system with simple structure and high computational efficiency. Finally, a benchmark G-system example is used to substantiate the efficiency of the new method. © The Author(s) 2017.

According to learning other models equipment test information of complex equipment in the development process, and making their own systems to improve the reliability of the case, a complex equipment reliability growth AMSAA-ELP model based on explore learning promotion was developed, and the property was analyzed from different parameter values.

A flow injection post chemiluminescence (FI-PCL) reaction was found when astemizole was mixed with the CL reaction mixture of N-bromosuccinimide and calcein under alkaline conditions. Based on this observation, a simple and sensitive post chemiluminescence (PCL) technique for the assay of astemizole was described. Under the optimized conditions, the PCL values responded linearly to the concentration of astemizole in the range 1.0 × 10-3-3.0 μg/mL, with a detection limit of 7.0 × 10-4 μg/mL. The relative standard deviation was 1.7% for 1.0 × 10-2 μg/mL astemizole solution (n = 13). It was applied to the determination of astemizole in pharmaceutical preparations with satisfactory results. © 2013 Copyright Taylor and Francis Group, LLC.

All species live in space, and the research of spatial diseases can be used to control infectious diseases. As a result, it is more realistic to study the spatial pattern of epidemic models with space and time. In this paper, spatial dynamics of an epidemic model with nonlinear incidence rate is investigated. We find that there are different types of stationary patterns by amplitude equations and numerical simulations. The obtained results may well explain the distribution of disease observed in the real world and provide some insights on disease control. © 2014 Springer Science+Business Media Dordrecht.

Mathematical models are very useful in analyzing the spread and control of infectious diseases which can be used to predict the developing tendency of the infectious disease, determine the key factors and to seek the optimum strategies of disease control. As a result, we investigated the pattern dynamics of a spatial epidemic model with logistic growth. By using amplitude equation, we found that there were different types of stationary patterns including spotted, mixed, and stripe patterns, which mean that spatial motion of individuals can form high density of diseases. The obtained results can be extended in other related fields, such as vegetation patterns in ecosystems. © 2014 Elsevier B.V. All rights reserved.

OBJECTIVE: To understand whether hepatitis E virus (HEV) was infectious in sheep in Xinjiang. METHODS: We used reverse transcription-nested polymerase chain reaction(RT-nPCR) to detect HEVRNA in feces. The feces were collected from sheep with positive anti-HEV antibodies in a sheep farm in Xinjiang Autonomous Region. RESULTS: Six of 54 (11.11%) sheep were positive for HEV RNA. PCR amplification products were cloned, sequenced and analyzed. The homology among HEV of the 6 sheep HEV ORF2 189bp nucleotide amplification sequences was 99.38%-100%. They should belong to the same genotype. They were respectively compared with HEV genotype I, II, III and IV corresponding 189bp nucleotide sequences. The average homology was 78.67%-85.33%, 81.33%-82.67%, 78.67%-84.00% and 84.67%-95.36%. The maximum homology between 6 nucleotide amplification sequences and one sequence of genotype IV was 94.04%-95.36%. Based on sequence of the nucleic acid fragments, a phylogenetic tree was constructed. Six sheep HEV ORF2 189bp nucleotide amplification sequences in this study and bovine HEV, swine HEV and human HEV locate the same evolutionary vine and belong to genotype IV. CONCLUSION: The finding suggested that infection of HEV probably exists in the sheep group in Xinjiang Autonomous Region and the sheep may be a new animal host except swine in origins of HEV infection.

To examine Prion protein(PrP) expression and its clinical significance in oral mucosa, oral leukoplakia, oral squamous cell carcinoma(OSCC) and its subgroups. Expression of PrP in OSCC, oral leukoplakia and mucosa specimen was detected by immunohistochemistry. The association between the expression and gender, TNM clinical stages, pathological grades was evaluated. The positive expression rate of PrP in normal, oral leukoplakia and OSCC tissues was 15% (3/20) , 42% (11/26) and 95% (80/84) , respectively. There was a significant difference between the expression of PrP in leukoplakia and in high, moderately and poorly differentiated OSCC(P < 0.05). The positive expression rate was increased with the declining of pathological differentiation (P < 0.05). There was no significant difference in PrP expression among lymph node metastasis and gender. PrP expression of stages I and II was up-regulated with the decreased differentiation (P < 0.05). There was no significant difference in PrP expression between stage III and IV (P > 0.05). Between stages I+II and III+IV in the overa II expression of PrP, there was a significant difference(P < 0.05). The high expression of PrP in OSCC and the progressive expression from leukoplakia to OSCC was closely related to the carcinogenesis of OSCC, pathologic stage and clinical TNM stage.
