Research on brand valuation models based on triangular fuzzy matrix game

Market competition has entered into the era of brand competition with economic growth. Brand evaluation represents an important approach for brand management and value enhancement. In this paper, an analysis was made, based on the triangular fuzzy matrix game theory, on the profits and losses incurred by participating enterprises and evaluating institutions due to their adoption of different game strategies. The applications of triangular fuzzy matrix game theory were expanded to the brand valuation field, and a theoretical method for evaluating the current evaluation models was proposed

The Impact of Online Word-of-mouth and Negative Media Exposure on Consumer Habitual Skepticism: The Mediating Effect of Attribution

How did habitual skepticism come into being? In this research，the causes of consumer habitual skepticism are explored from the perspective of attribution. We put forward two important antecedent variables, negative online word-of-mouth and negative media exposure. The study results show that the higher the negative word-of-mouth perception is, the higher the stability and controllability of consumer attribution will be, and the higher the degree of consumer habitual skepticism will be. The higher the intensity of negative media exposure is, the higher the stability and controllability of consumer attribution will be, and the higher the degree of consumer habitual skepticism will be. We test this framework through two experiments. Study 1 investigates the influence of negative word-of-mouth spread and media exposure on consumer habitual skepticism. Study 2 investigates the effect of two independent variables on consumer habitual skepticism from an overall point of view and explore the mediation effect of attribution

Investigating Bottom-Quark Yukawa Interaction at Higgs Factory

Measuring the fermion Yukawa coupling constants is important for understanding the origin of the fermion masses and its relationship to the spontaneously electroweak symmetry breaking. On the other hand, some new physics models will change the Lorentz structure of the Yukawa interactions between the standard model (SM) fermions and the SM-like Higgs boson even in their decoupling limit. Thus the precisely measurement of the fermion Yukawa interactions is a powerful tool of new physics searching in the decoupling limit. In this work, we show the possibility of investigating the Lorentz structure of the bottom-quark Yukawa interaction with the 125GeV SM-like Higgs boson at future $e^+e^-$ colliders.Comment: 8 pages, 7 figure

Tetra-μ-acetato-κ8 O:O′-bis­{[2-(2-fur­yl)-1-(2-furylmeth­yl)-1H-benzimidazole-κN 3]copper(II)}

The title complex, [Cu2(CH3COO)4(C16H12N2O2)2], forms a dimer of the paddle-wheel type located on a crystallographic inversion centre. The two CuII atoms [Cu⋯Cu = 2.7254 (11) Å] are bridged by four acetate anions. The geometry of the polyhedron around the metal centre can be described as tetra­gonal-pyramidal derived from the calculation of the value τ = 0.0018. The apical positions of the tetra­gonal-pyramidal copper coordination polyhedra are occupied by the N atoms of 2-(2-fur­yl)-1-(2-furylmeth­yl)-1H-benzimidazole ligands. In the crystal structure, mol­ecules are linked into a chain by inter­molecular C—H⋯O hydrogen bonds parallel to [010]. Two furan rings are disordered over two positions in ratios of 0.55:0.45 and 0.69:0.31

A Planar Low-Profile Meander Antenna Design for Wireless Terminal Achieving Low RF Interference and High Isolation in Multi-Antenna Systems

In this article, a meander line internal antenna used for wireless terminal is proposed. The current of this antenna is mostly distributed on the antenna radiator itself, rather than on the main board of the wireless device. As a result, the chance of having radiofrequency (RF) interference issues, which usually result in receiver desensitization in wireless radios, can be significantly reduced. The antenna has good radiation performance in the vertical polarization with a low physical profile, compared with the existing antenna designs for typical wireless terminals. The antenna has efficiency similar to the monopole antenna with much less reference/ground plane dependence, achieving lower RF interference, which is demonstrated by the noise coupling measurements in a predefined digital clock - antenna configuration. Furthermore, the mutual coupling (i.e., isolation) between two such antennas is studied and the envelope correlation coefficient between the two antennas is found to be low. A router assembled with the two proposed antennas is tested, and the total isotropic sensitivity is found lower compared with monopole antennas, due to the characteristics of low RF interference and high isolation of the proposed antenna

Acupuncture for the Treatment of Oculomotor Paralysis: A Pilot Randomised Controlled Trial

This study consisted of a single centre randomised controlled trial with two parallel arms: an acupuncture group ( = 20) with 27 affected eyes and a sham group ( = 20) with 23 affected eyes. Participants in the acupuncture group received acupuncture treatment once daily, three times weekly for four weeks. Participants assigned to the control group received sham acupuncture, the same protocol as that used for the acupuncture group but without insertion of needles into the skin. The primary outcome measure was the cervical range of motion (CROM) score. Secondary outcome measures were the palpebral fissure size, response rate, and adverse events. All 40 participants completed the study. In the comparison of acupuncture and sham acupuncture, a significant difference was observed between acupuncture and sham acupuncture in CROM score (21.37 ± 15.16 and 32.21 ± 19.54, resp.) ( < 0.05) and palpebral fissure size (7.19 ± 2.94 and 5.41 ± 2.45, resp.) ( < 0.05). Response rate was also significantly different in the acupuncture group ( < 0.05). No adverse events were reported in both groups in this study. In summary, it was demonstrated that acupuncture had a feasibility positive effect on oculomotor paralysis

Analysis of Asperger Syndrome Using Genetic-Evolutionary Random Support Vector Machine Cluster

Asperger syndrome (AS) is subtype of autism spectrum disorder (ASD). Diagnosis and pathological analysis of AS through resting-state fMRI data is one of the hot topics in brain science. We employed a new model called the genetic-evolutionary random Support Vector Machine cluster (GE-RSVMC) to classify AS and normal people, and search for lesions. The model innovatively integrates the methods of the cluster and genetic evolution to improve the performance of the model. We randomly selected samples and sample features to construct GE-RSVMC, and then used the cluster to classify and extract lesions according to classification results. The model was validated by data of 157 participants (86 AS and 71 health controls) in ABIDE database. The classification accuracy of the model reached to 97.5% and we discovered the brain regions with significant differences, such as the Angular gyrus (ANG.R), Precuneus (PCUN.R), Caudate nucleus (CAU.R), Cuneus (CUN.R) and so on. Our method provides a new perspective for the diagnosis and treatment of AS, and a universal framework for other brain science research as the model has excellent generalization performance
