Lambda表达式可以表示闭包，最早出现C#3.0,随着时间推移新版本JavaScript、Java8，Pathton等语言也都开始支...
The lambda symbol (λ) representing the 11th letter of the Greek alphabet is often used in physics, mathematics and computer science, where it carries different meanings. In computer science, the concept of lambdas dates back tolambda calculus(λ-calculus) introduced by American mathematician and l...
For this set of parameters, we find a negative value in the effective equation of state, however, the model has a very different pattern of the Hubble parameter from the standard scenario.doi:10.1134/S0202289321010084YuHong FangSchool of Physics and Astronomy, Sun Yat-Sen University, Zhuhai, ...
When you encounter an error value in a cell a warning symbol appears, displayed in the image above. Press with mouse on it to see a pop-up menu that lets you get more information about the error. The first line describes the error if you press with left mouse button on it. The secon...
Lambda particle In particle physics, the Lambda particle is any one of a number of baryons containing an up quark, a down quark, and a third quark such as that

where the symbol A is the anti-symmetrization operator, and A=1−P14−P24−P34. [σ]=[222] gives the total color symmetry and all other symbols have their usual meanings. ϕB and ϕM are the q3 and q¯q cluster wave functions, respectively. From the variational principle, afte...
Prove that p|(4^q+1)prove that (q over p) =1 where (q over p) denotes the legendre symbol. Let \lambda and \mu be two real numbers. Show that the Wronskian W[y1, y2](t) = 0, where (a) y1 = e \lambda t sin(...
where the hard kernel H is derived from the diagrams in Fig. 1, \Psi _{\Lambda _b} and \Psi _{P} stand for the \Lambda _b baryon and proton wave functions, respectively, and \mu is the factorization scale. The symbol \otimes represents the convolution in the momentum fractions and...
The transverse single spin asymmetry can be utilized to extract the information of the Sivers function, and has been intensively investigated in the past two decades from both experimental and theoretical aspects. The first non-zero Sivers asymmetry was measured by the HERMES Collaboration at DESY in...
