two dimensional space time/ A1110C Axiomatic field theories A1130Q Spontaneous symmetry breaking in particle physicsWe prove that in two-dimensional space-time, symmetry transformations which are generated by Poincar茅 covariant currents can not be spontaneously broken. This is also the case with the...
In this work, we investigate the ejection process of a polymer in a quasi two-dimensional space and verify the scaling theory. We confine the polymer in a disklike cavity and study its ejection, through a small pore situated on the side of the cavity, into an outer slit space. The disk...

Some interpolation on two dimensional Euler space of triangular domain is studied. 主要研究了二维欧氏空间三角域上的插值问题. 互联网 Automatic image thresholding based on the two - dimensional Maximum Correlation Criterion ( MCC ) is proposed. ...
The gate voltage creates an ionic space charge at the glass–device interface (Fig. 1a). Carrier concentration in the device can be fixed by lowering the temperature below T d, thus freezing the accumulated space charge at the interface and annulling ionic mobility in the glass substrate (...
This paper investigates the space hierarchies of the language classes for two-dimensional Turing machines (2-TM's), two-dimensional pushdown automata (2-PDA's) and two-dimensional counter automata (2-CA's) with small space. We show that (1) if L(n) is space constructible by a 2-TM, ...
Study of a Global Design Space Exploration Method for Aerospace Vehicles In the early stages of the design process of aerospace vehicles, the search for optimal configurations encompasses a broad range of possibilities, and the use of local optimization tools may risk missing the best designs. There...
During this study, we consider the LS analysis, explicit solutions, and conservation laws of the TFFE in two-dimensional space of the subordinate shape:(1)Dtαu(x,t)=uxx(x,t)+λu(x,t)(1−u(x,t)),where x∈R, t≥0, 1≥α>0, and λ∈R. Herein, u(x,t) is unknown funct...
Note that x and y (columnandrow) are abstract coords inside the grid, they are integer values starting from 0. Naturally, w and h (widthandheight) also take up space in the same coordinate system, which reveals the smallest unit of a grid: thecell.You could say, for example, that th...
(S, Se), which belong to the space group Pnma, exhibit a typical layered 2D structure feature along thecdirection. The reduction in the dimensionality of these materials has been proved as one of the most efficient methods to enhance their ZT values since the Seebeck coefficient increases due...
