Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions
FEBS Letters, EarlyView.We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Simultaneous rational approximation of a function and its derivatives in the complex plane
Journal of Approximation Theory, 1985 Some aspects of simultaneous rational approximation of a function f(z) and its derivatives on the unit circle are investigated. The function f(z) is assumed to be analytic in some annulus containing the unit circle, and given a nonnegative integer \(\ell\), \(\| f\| =\max \{\| f^{(j)}\|_{p,1}:0\leq j\leq \ell \},\) where \(\| \cdot \|_{p,1}\) is the ...

A Note on Rational Approximation with Respect to Metrizable Compactifications of the Plane
Extracta Mathematicae, 2016 In the present note we examine possible extensions of Runge, Mergelyan and Arakelian Theorems, when the uniform approximation is meant with respect to the metric ρ of a metrizable compactification (S, ρ) of the complex plane C.

Asymptotic analysis of flow near a glacier terminus
Journal of Glaciology, 2018 The non-linearly viscous ice flow in the vicinity of a glacier terminus, an observation region, depends crucially on the upstream flow as well as on the local surface and bed conditions.

Generalized deterministic linear model for coherent diffractive imaging
AIP Advances, 2022 A linear model for coherent diffractive imaging (CDI) is proposed herein. In this model, CDI is expressed as a system of linear equations in the frequency domain of an object and illumination.

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Is Gauss quadrature better than Clenshaw-Curtis? [PDF]
, 2006 We consider the question of whether Gauss quadrature, which is very famous, is more powerful than the much simpler Clenshaw-Curtis quadrature, which is less well-known.

Holographic equilibration in confining gauge theories under external magnetic fields
Nuclear Physics B, 2017 We investigate the effect of external magnetic fields on equilibration in the improved holographic QCD theory in the deconfined phase using the AdS/CFT correspondence.

POLYGONAL SHAPES DETECTION IN 3D MODELS OF COMPLEX ARCHITECTURES [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015 A sequential application of two global models defined on a variational framework is proposed for the detection of polygonal shapes in 3D models of complex architectures.

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.
