Payoff Matrix’s Effect on Trust Game Paradigm

Zenghui Li, Shuo Ran, Zehao Huang, Shimeng Yang, Rongrong Pu
This report first sorted out the definition of trust and found that researchers did not have a unified definition of trust. But trust includes two core characteristics: dependence and risk. Then we introduce the measurement methods of trust, including the trust game paradigm and its variants, in which the binary trust game paradigm and the three parameters in the payoff matrix of trust game paradigm are introduced; those three parameters are cost, benefit and temptation. Since previous studies e...

The Significance of Particle’s Density in Quantum Field Theory

Eliahu Comay
The paper emphasizes the significance of density of an elementary massive quantum particle. In quantum field theory, a quantum function of an elementary particle takes the form of Ψ(r,t). This kind of function is used for putting the inner product of the corresponding Hilbert space in the form of an appropriate integral, and the inner product of a function with itself depends on the particle’s density. Density also affects the multi-particle Fock space, because this space relies on si...

H. O. Amusa, S. D. Ogungbenro, T. D. Makanju, O. O. Okunlola, T. M. Adeoti, T. A. Oseni, I. A. Adebisi, F. L. Amusa
A total of (90) day old broilers were used for the study to determine the carcass characteristics and organ weight changes of broiler finisher fed graded levels of acid soaked Cajanus cajan seed meal diet. The birds were randomly assigned into 3 dietary treatments of 30 birds consisting of 3 replicates of (10) birds per replicates in a completely randomized design experiment. The seeds used were purchased from Towobowo market in Igboora. The raw pigeon pea seeds were pre-treated by soakin...

Characteristics and Significance of X-Ray Fluorescence Anomaly of Granite Pegmatite Rare Metal Deposit in Renli, Hunan

Long Zhang
In the granite pegmatite niobium-tantalum rare metal mining area in Renli, Pingjiang County, Hunan Province, the multi-element X-ray fluorescence measurement of soil was carried out using a handheld X-ray fluorometer on three survey lines passing through known veins. The element combination and amplitude of the mineral-induced X-ray fluorescence anomaly and the spatial correlation between mineral-induced anomalies and the ore body are studied. The results show that there are positive anomalies o...
