Notes:原型同样是常用的3维空间的\{\vec{i},\vec{j},\vec{k}\}。这里的basis\{e_i\}并不一定是arrow，“长度”并不一定为1，也并不一定“正交”。比如\mathbb{R}^2中的2-tuple(x_1,x_2)，basis可以取e_1=(2,0),e_2=(1,1)。3.线性泛函(Linear Functional)f\in\mathcal{L}(V,\mathbb...

15.15 Dual Basis Vectors are Normal to Surfaces in the Covariant Vector Space We now derive the covariant basis vectors (er,eθ,eϕ) in spherical coordinates. In spherical coordinates, the covariant representation of vector V uses the dual basis vectors (er,eθ,eϕ) with upper indices and...
Adeno-associated virus (AAV) vectors are the highly effective gene delivery carriers owing to their strong receptor-mediated clathrin-31and caveolae-mediated endocytosis32, transcytosis33, and endosomal escape34. Based on our experimental results, it is tentatively suggested that the presence of specific...
the coordinate form of index i w.r.t. the basis 对偶基的存在定理 对偶空间(the dual space),代数方程(the linear forms),余向量(covectors) 说明:给定向量空间E,所有的由E映射到域(也是向量空间)的线性映射全体记为Hom(E,K),Hom(E,K)也是个向量空间,并且称之为E的对偶空间。
Vectors for expression of Cas9 and sgRNA components in human cells are derived, respectively, from the MSP469 and BPK1520 plasmids described previously7. Both plasmids were obtained through Addgene. The MSP469 plasmid encodes the VQR variant; to generate isogenic Wt, KG, VRKG, and VRVRFRR pla...
We firstly provided a general six-dimensions screw form of vectors and matrices that can directly match the mechanical engineering parameters of a rigid body, to replace the currently three-dimensional dual form. On this basis, the representation and operation of six-dimensional dual screws are ...
We introduce the notion of imaginary vector in the dual canonical basis of $U_q(n)$, and we give examples of such vectors for types $A_n (n\ge 5)$, $B_n (n\ge 3)$, $C_n (n\ge 3)$, $D_n (n\ge 4)$, and all exceptional types. This disproves a conjecture of ...
the leap: Treat these two functions as vectors. In particular, think of them as basis vectors ...
On the basis of VoxelMorph framework, we propose an VoxelMorph Dual Attention CNN Architecture, an attention enhanced approach that further inhibit the useless information in the spatial field and improve the model accuracy. We learn the network parameters in an unsupervised fashion. We combine the ...
