Generating Functions for Coherent Intertwiners

open access: yes, 2012
We study generating functions for the scalar products of SU(2) coherent intertwiners, which can be interpreted as coherent spin network evaluations on a 2-vertex graph. We show that these generating functions are exactly summable for different choices of

Conformally Flat Manifolds [PDF]

open access: yesProceedings of the National Academy of Sciences, 1972
This note describes some new examples of conformally flat manifolds, as a step toward a classification of such manifolds up to conformal equivalence.

Targeting TNBC: core–shell polycationic polyurea dendrimers with inherent anticancer activity

open access: yesFEBS Open Bio, EarlyView.
Core–shell polycationic PURE dendrimers were tested in TNBC‐derived tumor models. Both formulations selectively targeted TNBC and effectively reduced tumor volume. PUREG4‐OEI48 suppressed tumor growth without detectable toxicity, whereas PUREG4‐OCEI24, despite showing efficacy, induced hepatic toxicity.

Signatures and flatness.

open access: yesJournal für die reine und angewandte Mathematik (Crelles Journal), 1993
Let \(Y\subset\mathbb{R}^ n\) be a codimension one analytic set, and fix a signature \(\sigma\) on \(\mathbb{R}^ n\backslash Y\) \((\sigma\) associates a \(\text{sign}+1\) or \(-1\) to each connected component of \(\mathbb{R}^ n\backslash Y)\). The signature \(\sigma\) is admissible at \(x\in Y\) when the germ \(\sigma_ x\) is induced by a germ of ...

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae

open access: yesFEBS Open Bio, EarlyView.
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...

Design and Performance Evaluation of a Flatness-Based Controller for a Three-Phase Three-Level NPC Shunt Active Power Filter

open access: yesDesigns
The widespread adoption of nonlinear loads in industry has introduced significant power quality issues in electric power distribution grids. The integration of these nonlinear loads has led to the proliferation of serious power quality problems such as ...

On quantum state of numbers [PDF]

open access: yes, 2013
We introduce the notions of quantum characteristic and quantum flatness for arbitrary rings. More generally, we develop the theory of quantum integers in a ring and show that the hypothesis of quantum flatness together with positive quantum ...

Anomalies, D-flatness and Small Instantons

open access: yes, 1995
Recently, Witten has proposed a mechanism for symmetry enhancement in $SO(32)$ heterotic string theory, where the singularity obtained by shrinking an instanton to zero size is resolved by the appearance of an $Sp(1)$ gauge symmetry. In this short letter,

Engineering tandem VHHs to target different epitopes to enhance antibody‐dependent cell‐mediated cytotoxicity

open access: yesFEBS Open Bio, EarlyView.
Tandem VHH targeting distinct EGFR epitopes were engineered into a monovalent bispecific antibody (7D12‐EGA1‐Fc) with more potent ADCC without increasing affinity to EGFR. Structural modeling of 7D12‐EGA1‐Fc showed cross‐linking of separate EGFR domains to enhance CD16a engagement on NK cells.

Factors of estimating flatness error as a surface requirement of exploitation

open access: yesMetalurgija, 2015
This study considers the impact of surface quality (surface roughness) on estimating flatness error when measurements are performed using coordinate measuring machine (CMM). Flatness error is estimated using various association methods and various sample
