FEBS Open Bio, EarlyView.dUTPases are involved in balancing the appropriate nucleotide pools. We showed that dUTPase is essential for normal development in zebrafish. The different zebrafish genomes contain several single‐nucleotide variations (SNPs) of the dut gene. One of the dUTPase variants displayed drastically lower protein stability and catalytic efficiency as compared ...

On Discrete Time Wilson Systems
Journal of Mathematics, 2020 In this paper, we define the discrete time Wilson frame (DTW frame) for l2ℤ and discuss some properties of discrete time Wilson frames. Also, we give an interplay between DTW frames and discrete time Gabor frames.

Optimal dual frames for erasures II
Linear Algebra and its Applications, 2011 The authors continue the investigation on optimal dual frames for erasures, see \textit{J. Lopez} and \textit{D. Han} [Linear Algebra Appl. 432, No. 1, 471--482 (2010; Zbl 1181.42034)]. The main result of this paper is a characterization of all the frames with the property that the canonical dual frames are the unique optimal dual frames for erasures ...

HIV‐1 establishes immediate latency in T cells expressing the viral Nef protein
FEBS Open Bio, EarlyView.Nef is a viral protein often omitted from HIV‐1 reporter viruses. Consequently, its role in viral latency is unclear. We developed three novel dual reporter HIV‐1 derivatives that express Nef and allow for detection of latent and productive infection. Using these reporters, we show that Nef does not affect the establishment of immediate viral latency ...

INDIRECT SAMPLING in the CONTEXT of DUAL FRAME SURVEYS [PDF]
Under-coverage is one of the most common problems of sampling frames. To reduce the impact of coverage error on survey estimates several frames can be combined in order to achieve a complete (or nearly complete) coverage of the target population ...

core
FEBS Open Bio, EarlyView.Patatin domain‐containing (phospho)lipases are lipid‐hydrolyzing enzymes central to metabolism, membrane remodeling, and signaling. Their activity relies on precise co‐activation mechanisms involving protein–protein interactions and conformational rearrangements.

Decompositions of g-Frames and Duals and Pseudoduals of g-Frames in Hilbert Spaces
Journal of Function Spaces, 2015 Firstly, we study the representation of g-frames in terms of linear combinations of simpler ones such as g-orthonormal bases, g-Riesz bases, and normalized tight g-frames.

Pseudo-Duals of Frames with Applications
Applied and Computational Harmonic Analysis, 2001 Let \(\{x_n\}\) be a frame for a Hilbert space \(H\). A dual for \(\{x_n\}\) is a frame \(\{x_n^*\}\) for which \(x= \sum \langle x,x_n\rangle x_n^*= \sum \langle x,x_n^*\rangle x_n\) for all \(x\in H\). More generally, a pseudo-dual of \(\{x_n\}\) is any family \(\{x_n^*\}\) for which \(\langle x,y\rangle = \sum \langle x,x_n^*\rangle \langle x_n,y ...
