Product diffusion refers to the phenomenon that the later demand is dependent on the early sales. To investigate how a firm＇s advance selling strategy is affected by the effect of product diffusion, we consider a monopolist seller who sells a fashionable product in a market that comprises of myopic and strategic consumers over two periods （i.e., the advance selling season and the regular selling season）. For a linear product diffusion effect we fred that, when the effect of product diffusion is positive, the seller may set an extremely high advance selling price to induce the strategic consumers to purchase in the regular selling season, which is counter-intuitive. Moreover, the optimal procurement quantity for the seller may increase in the negative effect of product diffusion and decrease in the amount of strategic consumers. When we extend our model to consider a concave quadratic product diffusion effect, however, the optimal procurement quantity is concave in the amount of strategic consumers. Numerical studies are further presented to discuss the managerial insights.

In this work, the enthalpy of fusion and melting points of 2-（tert-butyl）-5-methylphenol （2B5MP） and 2-（tert-butyl）-4-methylphenol （2B4MP） were measured by differential scanning calorimetry （DSC）. The binary solid-liquid equilibrium （SLE） of both compounds were predicted by integrated computer aided system （ICAS） and measured by DSC. The corresponding eutectic molar composition is 0.6998 and the eutectic temperature is 281.96 K. The quasi-static heat capacities of 2B5MP and 2B4MP were evaluated by stochastic temperature modulation DSC technique （TOPEM）. The SLE experimental data were correlated using the Margules, Wilson, and non-random two liquid （NRTL） equations and a good agreement between measurement and calculation could be obtained.

OBJECTIVE： To investigate the association of E-selectin $128R polymorphisms with ischemic stroke. DATA SOURCES： A computer-based online search was conducted in PubMed, Elsevier, Ovid Database, the China National Knowledge Infrastructure, and Wanfang Database between January 1998 and December 2010. STUDY SELECTION： Case-controlled studies addressing the association of the E-selectin polymorphism and ischemic stroke were included in this review. The genotype distribution complied with the Hardy-Weinberg genetic equilibrium. The included reports were evaluated by two authors for strict quality screening. Meta-analysis software, REVMAN 5.1, was used to investigate heterogeneity, pooled odds ratio （OR） and 95% confidence interval （CO in individual studies. MAIN OUTCOME MEASURES： Genotype and allele distributions at the E-selectin $128R site. RESULTS： Six case-controlled studies were included after screening and application of inclusion and exclusion criteria. There was no heterogeneity in the genotype and allele frequencies, and no publication bias was found. Meta-analysis of the pooled data showed that the OR value of the （AC＋CC）/AA genotype was 1.93 （95% CI： 1.55 2.41, Z= 5.80, P 〈 0.000 01）, and the ORfor the C/A allele was 1.80 （95% CI： 1.47 2.22, Z= 5.59, P 〈 0.000 01） in the ischemic stroke group, compared with control group. Results of pooled data in Chinese subjects showed that the ORvalue of （AC＋CC）/AA was 2.36 （95% CI： 1.68 3.31, Z = 4.99, P 〈 0.000 01）, and the OR value of the C/A allele was 2.25 （95% CI： 1.63 3.12, Z= 4.89, P 〈 0.000 01）. CONCLUSION： Polymorphism of E-selectin S128R was significantly associated with susceptibility to ischemic stroke; the AC and CC genotypes as well as the C allele may be factors associated with susceptibility to ischemic stroke.

Sichuan Basin is a typical superimposed basin, which experienced multi-phase tectonic movements, meanwhile Sinian–Cambrian underwent complex hydrocarbon accumulation processes, causing exploration difficulties in the past 60 years. Based on the microscopic evidence of fluid inclusions, combined with basin-modelling, this paper determines stages and time of hydrocarbon accumulation, reconstructs evolution of formation pressure and dynamic processes of hydrocarbon accumulation in Sinian Dengying Formation-Cambrian Longwangmiao Formation of Gaoshiti-Moxi structure. Three stages of inclusions are detected, including a stage of yellow-yellowgreen fluorescent oil inclusions, a stage of blue fluorescent oil-gas inclusions and a stage of non-fluorescent gas inclusions, reflecting the study area has experienced a series of complex hydrocarbon accumulation processes, such as formation of paleo-oil reservoirs, cracking of crude oil, formation of paleo-gas reservoirs and adjustment to present gas reservoirs, which occurred during 219–188, 192–146 and 168–0 Ma respectively. During the period of crude oil cracking, Dengying Formation-Longwangmiao Formation showed weak overpressure to overpressure characteristics, then after adjustment of paleo-gas reservoirs to present gas reservoirs, the pressure in Dengying Formation changed into overpressure but finally reduced to normal pressure system. However, due to excellent preservation conditions, the overpressure strength in Longwangmiao Formation only slightly decreased and was still kept to this day.

Systems engineering is not a new discipline. However, up to now, there is little consensus on its exact definition and scope. The scopes of several disciplines (neighboring disciplines of systems engineering) overlap with that of systems engineering. In this paper, the methods to identify similarities and dissimilarities between systems engineering and its neighboring disciplines are discussed. The research of this paper is expected to be helpful for clarifying the definition and scope of systems engineering.
