Research has shown that social commerce influences consumer purchase intentions, but little attention has been paid to the perspectives of Generation Z and its growing purchasing power. This study aimed to provide insights into the mechanisms influencing Generation Z’s intentions to continue using social commerce platforms, focusing on China’s RED as a representative platform. Though the lens of the stimulus-organism-response model, we investigated the effects of RED’s technological environments on consumers’ intrinsic values, extrinsic values and online purchase intentions. The results showed that the mediating effects of intrinsic and extrinsic values were significant. The suggests that social commerce features positively influence consumers’ intrinsic and extrinsic values, which enhances their continuance intentions. The results of this study provide similar social commerce platforms with ideas on how to improve the design of their platforms to increase consumer continuance intentions in the post-COVID-19 era.
Z-Source Inverters, Controls, and Motor Drive Applications
Peng Fang Z.,Shen Miaosen,Joseph Alan The Korean Institute of Electrical Engineers 2005 KIEE International Transactions on Electrical Mach Vol.b5 No.1
This paper presents Z-source inverters, their controls,, and their systems for motor drives. System configurations, analysis, controls, and unique features of the new Z-source motor drive systems will be summarized and given. Simulation and experimental results demonstrate advantageous features over the traditional voltage- and current-source inverter systems.

The increasing pursuit of advanced aero-engines with lower ratio between the cost and performance has greatly promotedthe demanding of single crystal superalloys characterized by low cost and outstanding temperature capability. In this study,a novel low-cost single crystal superalloy was designed and the creep tests as well as micro-characterization were carried outon the experimental alloy. The results illustrated that the novel single crystal alloy exhibited an ideal microstructural stabilitywithout precipitating TCP phases, after long-term thermal exposure at the ultimate service temperature of third generationsingle crystal superalloys. Moreover, the experimental alloy with only 3 wt% Re addition demonstrated remarkable creepresistance and maintained a very low minimum creep rate at 1100 °C/137 MPa and 1120 °C/137 MPa, while the accumulationand coalescence of micro-pores had eventually led to the alloy fracture. Apart from that, the compact interfacial dislocationnetworks the 2nd γ′ phase were observed after high-temperature creep rupture, and the typical a < 010 > superdislocationswith relatively poor mobility was found at 1120 °C. At 760 °C/800 MPa, both the minimum creep velocity and entire creepstain was increased evidently, however, the ultimate creep rupture life of the alloy had still reached 200 h. The correspondingdeformation mechanism was identified as the combination of superdislocation pairs shearing and a/3 < 121 > partial dislocationcutting the γ′ phase with a SISF being generated. In general, the novel single crystal alloy characterized by remarkablemechanical properties and cost reduction possesses a great potential for future application in the advanced aircraft engines.

<P><B>Abstract</B></P> <P>The production of <SUP> Z 0 </SUP> bosons at large rapidities in Pb–Pb collisions at <SUB> s NN </SUB> = 5.02 TeV is reported. <SUP> Z 0 </SUP> candidates are reconstructed in the dimuon decay channel ( <SUP> Z 0 </SUP> → <SUP> μ + </SUP> <SUP> μ − </SUP> ), based on muons selected with pseudo-rapidity − 4.0 < η < − 2.5 and <SUB> p T </SUB> > 20 GeV/ c . The invariant yield and the nuclear modification factor, <SUB> R AA </SUB> , are presented as a function of rapidity and collision centrality. The value of <SUB> R AA </SUB> for the 0–20% central Pb–Pb collisions is 0.67 ± 0.11 (stat.) ± 0.03 (syst.) ± 0.06 (corr. syst.) , exhibiting a deviation of 2.6<I>σ</I> from unity. The results are well-described by calculations that include nuclear modifications of the parton distribution functions, while the predictions using vacuum PDFs deviate from data by 2.3<I>σ</I> in the 0–90% centrality class and by 3<I>σ</I> in the 0–20% central collisions.</P>

High-current accelerators have many important applications in Z-pinches, high-power microwaves, and free electron lasers, imploding liners and radiography and so on. Research activities on Zpinches, imploding liners, radiography at the Institute of Fluid Physics (IFP) are introduced. Several main high-current accelerators developed and being developed at IFP are described, such as the Linear Induction Accelerator X-Ray Facility Upgrade (LIAXFU, 12 MeV, 2.5 kA, 90 ns), the Dragon-I linear induction accelerator (20 MeV, 2.5 kA, 60 ns), and the Primary Test Stand for Z-pinch (PTS, 10 MA, 120 ns). The design of Dragon-II linear induction accelerator (20 MeV, 2.5 kA, 3 × 60 ns) to be built will be presented briefly.
Primary Leiomyosarcoma of the Breast: A Case Report
Zülfikar Karabulut,Hampar Akkaya,Gökhan Moray 한국유방암학회 2012 Journal of breast cancer Vol.15 No.1
Primary leiomyosarcoma of the breast is an extremely rare tumor, accounting for less than 1% of all breast tumors and only 24 cases have been reported in the English medical journals. It is quite difficult to diagnose leiomyosarcoma preoperatively. Establishing an accurate diagnosis is very important in planning treatment. When preoperative diagnosis can be achieved before or during the operation, wide resection should be performed. There is no need for axillary lymph node dissection. In this case report, we present a case involving primary leiomysarcoma of the breast in a 48-year-old woman and we discuss optimal treatment options.
