On the convolution inequality $f \geq f\star f$ [PDF]
, 2020 We consider the inequality $f \geqslant f\star f$ for real integrable functions on $d$ dimensional Euclidean space where $f\star f$ denotes the convolution of $f$ with itself. We show that all such functions $f$ are non-negative, which is not the case for the same inequality in $L^p$ for any $1 < p \leqslant 2$, for which the convolution is defined. We

Synergy of cations in high entropy oxide lithium ion battery anode
Nature Communications, 2023 Though high entropy oxides have been explored as possible conversion-type negative electrodes for Li-ion batteries, the roles of the different elements remain unclear. Here the authors determine the behavior of each element during electrochemical cycling

Magnetic anisotropy of graphene quantum dots decorated with a ruthenium adatom
Beilstein Journal of Nanotechnology, 2013 The creation of magnetic storage devices by decoration of a graphene sheet by magnetic transition-metal adatoms, utilizing the high in-plane versus out-of-plane magnetic anisotropy energy (MAE), has recently been proposed. This concept is extended in our

Erratum to: An Entropy Functional for Riemann-Cartan Space-Times [PDF]
Int J Theor Phys 51 (2012) 362-373; Erratum - Int J Theor Phys. 52
(2013) 4592-4593, 2012 We correct the entropy functional constructed in Int. J. Theor. Phys. 51:362 (2012). The 'on-shell' functional one obtains from this correct functional possesses a holographic structure without imposing any constraint on the spin-angular momentum tensor of matter, in contrast to the conclusion made in the above paper.

int-h: an int mutation of phage λ that enhances site-specific recombination [PDF]
Cell, 1980 Abstract The mutation int -h3 maps in the int gene of coliphage λ and results in the synthesis of an integrase with enhanced activity, which is manifested by an ability to support λ site-specific recombination relatively efficiently under conditions where the wild-type integrase functions inefficiently. The level of site-specific recombination seen

EXAFS and electrical studies of new narrow-gap semiconductors: InTe$_{1-x}$Se$_x$ and In$_{1-x}$Ga$_x$Te [PDF]
J. Phys. Chem. Solids 61, 2007 (2000), 2018 The local environment of Ga, Se, and Tl atoms in InTe-based solid solutions was studied by EXAFS technique. It was shown that all investigated atoms are substitutional impurities, which enter the In(1), Te, and In(2) positions in the InTe structure, respectively.
