An Algorithm for Computing $m$-Tight Error Linear Complexity of Sequences over $GF(p^{m})$ with Period $p^{m}$Sep 21 2011The linear complexity (LC) of a sequence has been used as a convenient measure of the randomness of a sequence. Based on the theories of linear complexity, $k$-error linear complexity, the minimum error and the $k$-error linear complexity profile, the ... More
A Note on the Non-Commutative Wess-Zumino ModelSep 11 2000Oct 16 2000We show that the noncommutative Wess-Zumino (NCWZ) Lagrangian with permutation terms in the interaction parts is renormalizable at one-loop level by only a wave function renormalization. When the non-commutativity vanishes, the logarithmic divergence ... More
Congruences for an arithmetic function from 3-colored Frobenius partitionsMar 02 2010Apr 27 2010Let $a(n)$ defined by $\sum_{n=1}^{\infty}a(n)q^n := \prod_{n=1}^{\infty}\frac{1}{(1-q^{3n})(1-q^n)^3}.$ In this note, we prove that for every non-negative integer $n$, a(15n+6) \equiv 0\pmod{5}, a(15n+12) \equiv 0\pmod{5}. As a corollary, we obtained ... More
Mapping properties of operator-valued pseudo-differential operatorsApr 10 2018In this paper, we investigate the mapping properties of pseudo-differential operators with operator-valued symbols. Thanks to the smooth atomic decomposition of the operator-valued Triebel-Lizorkin spaces $F_1^{\alpha,c}(\mathbb{R}^d,\mathcal{M})$ obtained ... More
Leaking Information Through Cache LRU StatesMay 20 2019The widely deployed Least-Recently Used (LRU) cache replacement policy and its variants are an essential component of modern processors. However, we show for the first time in detail that the LRU states of caches can be used to leak information. The LRU ... More
Kinetic studies on using photocatalytic coatings for removal of indoor volatile organic compoundsDec 16 2018Titanium dioxide (TiO2) is a known photocatalyst with a capability of decomposing organic substance. However, the photocatalysis of the pure TiO2 is not effective for the indoor environment due to a lack of the ultraviolet irradiation inside the building. ... More
Cookie Monster Plays GamesJul 06 2014We research a combinatorial game based on the Cookie Monster problem called the Cookie Monster game that generalizes the games of Nim and Wythoff. We also propose several combinatorial games that are in between the Cookie Monster game and Nim. We discuss ... More
