New bounds and approximations for total π-electron energy: A critical test [PDF]
Kragujevac Journal of Science, 2014 The quality and correlating ability of some recently deduced bounds and approximate formulas for total π-electron energy are tested on a sample of 106 Kekuléan benzenoid hydrocarbons.

Bounded Independence versus Symmetric Tests [PDF]
ACM Transactions on Computation Theory, 2019 For a test T ⊆ {0, 1} n , define k * ( T ) to be the maximum k such that there exists a k -wise uniform distribution over {0, 1} n

Improved Bounds for Testing Juntas [PDF]
, 2008 We consider the problem of testing functions for the property of being a k-junta (i.e., of depending on at most kvariables). Fischer, Kindler, Ron, Safra, and Samorodnitsky (J. Comput. Sys. Sci., 2004) showed that $\tilde{O}(k^2)/\epsilon$ queries are sufficient to test k-juntas, and conjectured that this bound is optimal for non-adaptive testing ...

Bounds for test exponents [PDF]
Compositio Mathematica, 2006 Suppose that R is a two-dimensional normal standard-graded domain over a finite field. We prove that there exists a uniform Frobenius test exponent b for the class of homogeneous ideals in R generated by at most n elements. This means that for every ideal I in this class we have that f^(p^b) belongs to I^([p^b]) if and only if f belongs to the ...

FEBS Letters, EarlyView.Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Lower Bounds on Query Complexity for Testing Bounded-Degree CSPs [PDF]
2011 IEEE 26th Annual Conference on Computational Complexity, 2011 In this paper, we consider lower bounds on the query complexity for testing CSPs in the bounded-degree model. First, for any ``symmetric'' predicate $P:{0,1}^{k} \to {0,1}$ except \equ where $k\geq 3$, we show that every (randomized) algorithm that distinguishes satisfiable instances of CSP(P) from instances $(|P^{-1}(0)|/2^k-ε)$-far from ...

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.
