Low frequency groans indicate larger and more dominant fallow deer (Dama dama) males. [PDF]
PLoS ONE, 2008 BACKGROUND: Models of honest advertisement predict that sexually selected calls should signal male quality. In most vertebrates, high quality males have larger body sizes that determine higher social status and in turn higher reproductive success ...

Research on correction algorithm of propagation error in wireless sensor network coding
EURASIP Journal on Wireless Communications and Networking, 2020 It is very difficult to deal with the problem of error correction in random network coding, especially when the number of errors is more than the min-cut of the network. We combine a small field with rank-metric codes to solve this problem in this paper.

The minimum rank problem over the finite field of order 2: Minimum rank 3
Linear Algebra and its Applications, 2009 Our main result is a sharp bound for the number of vertices in a minimal forbidden subgraph for the graphs having minimum rank at most 3 over the finite field of order 2. We also list all 62 such minimal forbidden subgraphs. We conclude by exploring how some of these results over the finite field of order 2 extend to arbitrary fields and demonstrate ...

On the minimum vector rank of multigraphs [PDF]
The Electronic Journal of Linear Algebra, 2010 The minimum vector rank (mvr) of a graph over a field F is the smallest d for which a faithful vector representation of G exists in F d . For simple graphs, minimum semidefinite rank (msr) and minimum vector rank differ by exactly the number of isolated vertices.

Sensors, 2022 Noise level is an important parameter for image denoising in many image-processing applications. We propose a noise estimation algorithm based on pixel-level low-rank, low-texture subblocks and principal component analysis for white Gaussian noise. First,

The (Minimum) Rank of Typical Fooling-Set Matrices [PDF]
, 2017 A fooling-set matrix has nonzero diagonal, but at least one in every pair of diagonally opposite entries is 0. Dietzfelbinger et al. '96 proved that the rank of such a matrix is at least $\sqrt n$. It is known that the bound is tight (up to a multiplicative constant). We ask for the "typical" minimum rank of a fooling-set matrix: For a fooling-set zero-

On the minimum skew rank of graphs [PDF]
ScienceAsia, 2014 The minimum skew rank mr (F;G) of a graphG over a field F is the smallest possible rank among all skew symmetric matrices over F whose (i;j)th entry (for i 6 j) is non-zero whenever ij is an edge in G and is zero otherwise. We characterize the graphs G with cut vertices over an infinite field F such that mr (F;G) = 4 determine the minimum skew rank of ...
