The results showed that the microstructure of the TiC-reinforced low alloy abrasion-resistant steel consisted of a martensite matrix and nano- and micro-sized TiC particles. Although the TiC particles consumed the C element in the matrix, thus reducing the hardness and strength of the experimental...
We present results for the three-loop top quark contributions to the ρ parameter in the limit of large top quark mass. The simultaneous dependence on the mass of the Higgs boson M H and the mass of the top quark m t is obtained from expansions in the range of M H around m t and ...
The scattering reactions of three equal-mass particles constrained to move in a straight line and interacting with each other via zero-range potentials have been analyzed on the basis of the extended R-matrix theory. The simplicity of the model facilitates an exposition of the complexities that re...

placed on an x-y plan.Given that particle A has a mass of 18 kg and its coordinate is (14,12).Particle B has a mass of 14 kg and its coordinate is (8,20).Particle C has a mass of 10 kg and its coordinate is (18,15).Find the center of mass of the system of particles.(...
Indeed, it is also guessed that the relaxation time to the average is controlled by the size of the system, i.e., the number of particles. Therefore, we cannot expect a fast relaxation in such a low-dimensional phase space as the one of the three-particle FPUT model. The averages on...
[23] put forward the concept of a virtual body spring based on the particle spring model. By introducing the original state of the model into the model change process, the elastic deformation process of the soft tissue model is more real, and the design of the three-dimensional mass–spring...
Let B be a Banach space and let T∈ℒ(B). A point z∈ Sp(T) is called a point of the discrete spectrum if it is an isolated point in Sp(T), if it has finite multiplicity and if the range of z - T is closed. Other points are points of the essential spectrum Spess(T). ...
