4-Carbamoylpiperidinium acetate monohydrate

Acta Crystallographica Section E, 2010
In the structure of the title compound, C6H13N2O+·C2H3O2−·H2O, the amide H atoms of the cations form centrosymmetric cyclic hydrogen-bonding associations incorporating two water molecules [graph set R42(8)], which are conjoint

2-(Phenylcarbonothioylsulfanyl)acetic acid

Acta Crystallographica Section E, 2010
The title compound, C9H8O2S2, can be used as a chain transfer agent and may be used to control the behavior of polymerization reactions. O—H...O hydrogen bonds of moderate character link the molecules into dimers. In the crystal, the dimers are

Magnetic detectability of a finite size paramagnet/superconductor cylindrical cloak

, 2014
Cloaking of static magnetic fields by a finite thickness type-II superconductor tube surrounded by a coaxial paramagnet shell is studied. On the basis of exact solutions to the London and Maxwell equations, it is shown that perfect cloaking is realizable

Conserved Charge Fluctuations from Lattice QCD and the Beam Energy Scan

, 2015
We discuss the next-to-leading order Taylor expansion of ratios of cumulants of net-baryon number fluctuations. We focus on the relation between the skewness ratio, $S_B\sigma_B = \chi_3^B/\chi_1^B$, and the kurtosis ratio, $\kappa_B\sigma_B^2 =\chi_4^B/\
