Emerging Roles of Small GTPases in Islet β-Cell Function
Cells, 2021 Several small guanosine triphosphatases (GTPases) from the Ras protein superfamily regulate glucose-stimulated insulin secretion in the pancreatic islet β-cell.

Flavor Singlet Contribution to the Structure Function $g_1$ at Small-x [PDF]
, 1996 The singlet contribution to the $g_1(x,Q^2)$ structure function is calculated in the double-logarithmic approximation of perturbative QCD in the region $x \ll 1$.

Small subharmonic functions [PDF]
Bulletin of the Australian Mathematical Society, 1984 Some time ago Barry [Proc. London Math. Soc. 12 (1962), 445–495] established the right connection between the smallest and largest values of small subharmonic functions on certain circles about the origin. The behaviour of functions extremal for this connection is investigated.

Functionalization of an Antisense Small RNA [PDF]
Journal of Molecular Biology, 2016 In order to explore the possibility of adding new functions to preexisting genes, we considered a framework of riboregulation. We created a new riboregulator consisting of the reverse complement of a known riboregulator. Using computational design, we engineered a cis-repressing 5' untranslated region that can be activated by this new riboregulator. As

The Small GTPases in Fungal Signaling Conservation and Function
Cells, 2021 Monomeric GTPases, which belong to the Ras superfamily, are small proteins involved in many biological processes. They are fine-tuned regulated by guanine nucleotide exchange factors (GEFs) and GTPase-activating proteins (GAPs).

Singlet structure function g_1 at small x and small Q^2
, 2006 Explicit expressions for the singlet g_1 at small x and small Q^2 are obtained with the total resummation of the leading logarithmic contributions. It is shown that g_1 practically does not depend on Q^2 in this kinematic region. In contrast, it would be

Exponentially small expansions of the Wright function on the Stokes lines [PDF]
, 2014 We investigate a particular aspect of the asymptotic expansion of the Wright function pΨq(z) for large |z|. In the case p = 1, q ⩾ 0, we establish the form of the exponentially small expansion of this function on certain rays in the z-plane (known as ...

On the probability distribution function of small scale interplanetary magnetic field fluctuations [PDF]
, 2004 In spite of a large number of papers dedicated to study MHD turbulence in the solar wind there are still some simple questions which have never been sufficiently addressed like: a)do we really know how the magnetic field vector orientation fluctuates in ...

Biogenesis, Trafficking, and Function of Small RNAs in Plants
Frontiers in Plant Science, 2022 Small RNAs (sRNAs) encoded by plant genomes have received widespread attention because they can affect multiple biological processes. Different sRNAs that are synthesized in plant cells can move throughout the plants, transport to plant pathogens via ...

Nuclear Shadowing in the Structure Function $F_3(x)$ [PDF]
, 1995 Nuclear modification of the structure function $F_3$ is investigated. Although it could be estimated in the medium and large $x$ regions from the nuclear structure function $F_2^A$, it is essentially unknown at small $x$.
