In words: The sum of squares of two real numbers equals the product of a complex number with one of the two real numbers as its real part and the other as its imaginary part, and the conjugate of the complex number thus formed. difference of squares 平方差 a^2-b^2=(a+b)(a-b) ...
本期专栏为 “谱图理论” 系列的第35期,将介绍耶鲁大学教授、两届哥德尔奖得主 Daniel A. Spielman 所著图书 《Spectral and Algebraic Graph Theory》 (电子版链接) 第三十五章 Ch35: The Conjugate Gradient …
Whole-brain models have proven to be useful to understand the emergence of collective activity among neural populations or brain regions. These models combine connectivity matrices, or connectomes, with local node dynamics, noise, and, eventually, transm
Initially each system was energy-minimized for 10,000 steps using the conjugate gradient algorithm51. Then, we relaxed the systems by applying restraints in a stepwise manner (for a total of ∼1 ns) using the standard CHARMM-GUI equilibration protocol46. Production runs were performed for ...
1. Identify the Expression: We start with the expression √5−√2. 2. Rationalization Concept: To convert this expression into a rational number, we can use the technique of rationalization. This involves multiplying by the conjugate of the expression. The conjugate of √5−√2 is √5+√...

First observation of the Σ- π+ π+ decay mode of the Λc baryon and its branching ratio relative to the Σ+ π+ π- mode We report the first observation (103±17 events) of the decay Λ + c →Σ π + π + and the charge conjugate. A measurement of the relative branching r....
Major microscope manufacturers use infinity-conjugate (that is, infinity-corrected) optical designs17, and thus we adopted the same convention for compatibility. The other constraints from commercial systems are the beam diameter at the objective back aperture and the maximal scan angle. These two ...
