A family of difference sets in non-cyclic groups A construction is given for difference sets in certain non-cyclic groups with the parameters v = q s+1{[ (q s+1 − 1) (q − 1)] + 1}, k = q s (q s+1 − 1) (q − 1), λ = q s (q s − 1) (q − 1)...
Exponent bounds for a family of abelian difference sets K.T. ArasuJames A. Davis2, Jonathan Jedwab, Siu Lun Ma, and Robert L. McFarland Abstract Which groups G contain difference sets with the parameters (υ, k,λ) = (q3 + 2q2,q2 + q,q), where q is a power of a prime pi Co...
Nontrivial difference sets in groups of order a power of 2 are part of the family of difference sets called Hadamard difference sets. In the abelian case, a group of order 2 2 t +2 has a difference set if and only if the exponent of the ... JA Davis,JE Iiams - 《Journal of Alg...
The bacteriophage λ integrase protein (λ Int) belongs to a family of tyrosine recombinases that catalyze DNA rearrangements. We have determined a crystal structure of λ Int complexed with a cleaved DNA substrate through a covalent phosphotyrosine bond. In comparison to an earlier unliganded struct...
In that sense, the large family of frustrated magnets34 with triangular, Kagome, and pyrochlore lattices, as well as the heterostructures with interfacial DMI35 would be prospective platforms to explore this new AHE. Unlike the conventional intrinsic AHE which has been limited to ferromagnets or ...

Moreover, its functioning has to minimize undesired production (and uncontrolled release) of greenhouse gases such as N2O21. In particular, the surface community is recognized to be a potential source of neutral lipids, a family of molecules of high added value usable for third-generation ...
Overexpressed pro-survival B-cell lymphoma-2 (BCL-2) family proteins BCL-2 and BCL-XL can render tumor cells malignant. Leukemia drug venetoclax is currently the only approved selective BCL-2 inhibitor. However, its application has led to an emergence of
