Engineering the thermal conductivity along an individual silicon nanowire by selective helium ion irradiation
Yunshan Zhao, Dan Liu, Jie Chen +10
The ability to engineer the thermal conductivity of materials allows us to control the flow of heat and derive novel functionalities such as thermal rectification, thermal switchin…
Factors of sums and alternating sums of products of -binomial coefficients and powers of -integers
Victor J. W. Guo, Su-Dan Wang
We prove that, for all positive integers , , and non-negative integers and with , the following two expressions \begin{align*}…
Proof of a conjecture of Kløve on permutation codes under the Chebychev distance
Victor J. W. Guo, Yiting Yang
Let be a positive integer and a real number. Let be a matrix with its entries $$ a_{i,j}=\left\{ \begin{array}{ll} x\ \ & \mbox{for} \ 1\leqslant j\…
A recursive algorithm for trees and forests
Song Guo, Victor J. W. Guo
Trees or rooted trees have been generously studied in the literature. A forest is a set of trees or rooted trees. Here we give recurrence relations between the number of some kind…
Factors of sums involving -binomial coefficients and powers of -integers
Victor J. W. Guo, Su-Dan Wang
We show that, for all positive integers , , and any non-negative integers and with , the expression $$ \frac{1}{[n_1]}{n_1+n_{m…
