Spectral Decomposition of Missing Transverse Energy at Hadron Colliders

We propose a spectral decomposition to systematically extract information of dark matter at hadron colliders. The differential cross section of events with missing transverse energy (MET) can be expressed by a linear combination of basis functions. In the case of $s$-channel mediator models for dark matter particle production, basis functions are identified with the differential cross sections of sub-processes of virtual mediator and visible particle production while the coefficients of basis functions correspond to dark matter invariant mass distribution in the manner of the K\"all\'en-Lehmann spectral decomposition. For a given MET data set and mediator model, we show that one can differentiate a certain dark matter-mediator interaction from another through spectral decomposition.Comment: 6+4 pages, 6 figures, PRL versio

Perceived Retail Crowding, Emotional Distance, and Consumer Response in Fashion Stores

The same degree of crowding can be perceived differently by different people depending on the consumers\u27 individual characteristics. The purpose of this study is to investigate the influence of crowding degree and perceived similarity with other customers in a store on the in-store emotion state and purchase intention. A lower perceived crowding degree resulted in a higher pleasure emotion state, and a higher perceived crowding degree, led to a higher arousal emotion state. The pleasure, arousal, and dominance emotion states and the purchase intention were found to be higher in the group that perceived a high similarity with other in-store customers. It was found that customers felt more positive emotions and had more positive behaviors when they perceived that they were similar to others in the store environment. This shows that the presence of other customers who were highly similar to themselves is an important factor in customers\u27 shopping behavior

125 GeV Higgs as a pseudo-Goldstone boson in supersymmetry with vector-like matters

We propose a possibility of the 125 GeV Higgs being a pseudo-Goldstone boson in supersymmetry with extra vector-like fermions. Higgs mass is obtained from loops of top quark and vector-like fermions from the global symmetry breaking scale f at around TeV. The mu, Bmu/mu \sim f are generated from the dynamics of global symmetry breaking and the Higgs quartic coupling vanishes at f as tan beta \simeq 1. The relation of msoft \sim $4\pi M_Z$ with f \sim mu \sim m_soft \sim TeV is obtained and large mu does not cause a fine tuning for the electroweak symmetry breaking. The Higgs to di-photon rate can be enhanced from the loop of uncolored vector-like matters. The stability problem of Higgs potential with vector-like fermions can be nicely cured by the UV completion with the Goldstone picture.Comment: 28 pages, 8 figure

Brand Image and Evaluation Factors of Fashion Product Advertisement

Brand image is a collection of things related with brand that consumers have in the memory (Keller, 1993) and corporations are making much efforts to build a brand image and advertisement has been used as a major method to inform the brand image. Advertisement is communication message performed for the purpose of positively change the consumer’s emotion for corporations, brands and trademarks

Social Network Analysis of Global Value Chain: Focused on Fabric Cotton

Companies try to establishing optimal production networks that can perform all stages of production activities at competitive cost and quality around the world. In this study, we try to determine the structure of the global value chain in the apparel industry using social network analysis. Data for analysis were created a matrix using 2005 and 2015 trade data about the top 10 trading partners in the import and export countries of cotton fabric (hs code 5208, 5209). China was the largest exporting country. Comparing the betweenness centrality and closeness centrality of exports of cotton fabrics, India and China are playing their role as mediating countries. Vietnamese cotton imports have increased significantly. The role of mediators in the importation of cotton fiber was continued by China, the United States, and European countries. We identified the part of the fashion industry structure by investigating the international trade patterns of cotton fabric

Changes in the Outdoor Wear Market: Focused on the South Korean Market

People have become interested in wellness and health, which has led to well-being trends and increased participation in activities. Therefore, the outdoor wear market has shown growth for several years. However, the outdoor wear market of South Korea is becoming saturated. Moreover, Outdoor wear consumers are tired of same design products. The sportswear companies are trying to develop athleisure products. Therefore, it is time to develop outdoor products for emotional approach. According to results, when consumers purchase outdoor wear, they consider the functionality of the materials more than they do when purchasing ordinary clothes. Outdoor wear consumers\u27 pursued images were classified into three types: urban, minimalist, and active. Outdoor wear selection criteria were classified into two types: instrumental function and expressive function. Outdoor wear brands need to qualify their products functionally and meet their segmented consumers\u27 demands by developing products depending on their image from the planning stage

Association of Bone Mineral Density With Hearing Impairment in Postmenopausal Women in Korea

Objectives Previous studies examining the association between osteoporosis (OP) and hearing loss (HL) have shown conflicting results. The objective of the present study was to examine the association between hearing impairment and OP in postmenopausal women, using appropriate statistical analyses. Methods Total 1,009 participants were included in the current study. The propensity score matched (PSM) cohort was defined as the cohort including participants diagnosed with OP and participants without OP. Three statistical models were developed where model 1 was unadjusted, model 2 included age, and model 3 included age, body mass index, alcohol intake, smoking habit, diabetes mellitus, hypertension, high density lipoprotein cholesterol, triglyceride level, vitamin D, and alkaline phosphatase. Results There were 776 and 233 participants in the groups diagnosed without and with OP, respectively. For propensity score matching, 233 pairs were selected from the 776 participants without OP. In the total cohort, using statistical models 2 and 3, no significant difference in the four hearing thresholds was identified between the 2 groups. Logistic regression indicated that, in model 3, participants with OP had a 1.128 (P=0.323) increased risk HL. A significant HL risk was not observed in participants with OP. Using statistical model 3, there were no significant associations among lumbar spine or femoral neck T-scores and changes in the hearing thresholds. In the PSM cohort, statistical models also showed similar results. Conclusion The current study did not demonstrate and association between bone mineral density and hearing impairment in the study population of postmenopausal Korean women

Test Platform Development of Vessel???s Power Management System Using Hardware- in-the-Loop-Simulation Technique

A PMS (Power Management System) controls vessel's power systems to improve the system efficiency and to protect a blackout condition. The PMS should be developed with considering the type and the capacity of the vessel???s power system. It is necessary to test the PMS functions developed for vessel???s safe operations under various sailing situations. Therefore, the function tests in cooperation with practical power systems are required in the PMS development. In this paper, a hardware-in-the-loop (HIL) simulator is developed for the purposes of the PMS function tests. The HIL simulator can be more cost-effective, more time-saved, easier to reproduce, and safer beyond the normal operating range than conventional off-line simulators, especially at early stages in development processes or during fault tests. Vessel's power system model is developed by using a MATLAB/SIMULINK software and by communicating between an OPAL-RT???s OP5600 simulator. The PMS uses a Modbus communication protocol implemented using LabVIEW software. Representative tests of the PMS functions are performed to verify the validity of the proposed HIL-based test platform

Ginseng Purified Dry Extract, BST204, Improved Cancer Chemotherapy-Related Fatigue and Toxicity in Mice

Cancer related fatigue (CRF) is one of the most common side effects of cancer and its treatments. A large proportion of cancer patients experience cancer-related physical and central fatigue so new strategies are needed for treatment and improved survival of these patients. BST204 was prepared by incubating crude ginseng extract with ginsenoside-β-glucosidase. The purpose of the present study was to examine the effects of BST204, mixture of ginsenosides on 5-fluorouracil (5-FU)-induced CRF, the glycogen synthesis, and biochemical parameters in mice. The mice were randomly divided into the following groups: the naïve normal (normal), the HT-29 cell inoculated (xenograft), xenograft and 5-FU treated (control), xenograft + 5-FU + BST204-treated (100 and 200 mg/kg) (BST204), and xenograft + 5-FU + modafinil (13 mg/kg) treated group (modafinil). Running wheel activity and forced swimming test were used for evaluation of CRF. Muscle glycogen, serum inflammatory cytokines, aspartic aminotransferase (AST), alanine aminotransferase (ALT), creatinine (CRE), white blood cell (WBC), neutrophil (NEUT), red blood cell (RBC), and hemoglobin (HGB) were measured. Treatment with BST204 significantly increased the running wheel activity and forced swimming time compared to the control group. Consistent with the behavioral data, BST204 markedly increased muscle glycogen activity and concentrations of WBC, NEUT, RBC, and HGB. Also, tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6), AST, ALT, and CRE levels in the serum were significantly reduced in the BST204-treated group compared to the control group. This result suggests that BST204 may improve chemotherapy-related fatigue and adverse toxic side effects
