Degree of simultaneous approximation by Birkhoff splines
Journal of Numerical Analysis and Approximation Theory, 2001 In the present note we study the degree of simultaneous approximation by certain Birkhoff spline interpolation operators. Special emphasis is on estimates in terms of higher order moduli of smoothness. This generalizes earlier results of Meir and Sharma,

Universal approximation theorem for Dirichlet series
International Journal of Mathematics and Mathematical Sciences, 2006 The paper deals with an extension theorem by Costakis and Vlachou on simultaneous approximation for holomorphic function to the setting of Dirichlet series, which are absolutely convergent in the right half of the complex plane.

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 ...

FEBS Open Bio, EarlyView.Chemoresistance in bladder cancer: Macrophage recruitment associated with CXCL1, CXCL5 and CXCL8 expression is characteristic of Gemcitabine/Cisplatin (Gem/Cis) Non‐Responder tumors (right side) while Responder tumors did not show substantial tumor‐stromal crosstalk (left side). All biological icons are attributed to Bioicons: carcinoma, cancerous‐cell‐

FEBS Open Bio, EarlyView.Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Simultaneous Approximation from PSI Spaces
Journal of Approximation Theory, 1995 For a principal shift invariant space \(S (\varphi)\), generated by \(\varphi \in W_ 2^ m (\mathbb{R}^ s)\), a necessary and sufficient condition is found for determining whether \(S (\varphi)\) provides simultaneous approximation of order \((m,k)\). For a certain type of generating function \(\varphi\) it is proved that this necessary and sufficient ...

FEBS Open Bio, EarlyView.Mouse pre‐implantation development involves a transition from totipotency to pluripotency. Integrating transcriptomics, epigenetic profiling, low‐input proteomics and functional assays, we show that eight‐cell embryos retain residual totipotency features, whereas cytoskeletal remodeling regulated by the ubiquitin‐proteasome system drives progression ...

Effective simultaneous approximability of reals
Theoretical Computer Science, 2002 The effective simultaneous approximability of real vectors and sets of reals is studied. A hierarchy of real vectors based on the Kolmogorov complexity of computable approximations is constructed. We prove that the hierarchy is nontrivial at the bottom levels but collapses on the top levels.
