Immunization of networks with community structure

, 2009
In this study, an efficient method to immunize modular networks (i.e., networks with community structure) is proposed. The immunization of networks aims at fragmenting networks into small parts with a small number of removed nodes.

Left Ventricular Outflow Tract Geometry as a Predictor of Permanent Pacemaker Implantation After Transcatheter Aortic Valve Implantation Using the Evolut Series

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Predicting the need for permanent pacemaker implantation (PPM) after transcatheter aortic valve implantation (TAVI) is crucial for procedural planning and patient counseling. Aims To evaluate whether left ventricular outflow tract (LVOT) morphology, specifically a tapered configuration, predicts conduction disturbances requiring PPM

The Verification of Co‐Axiality of the Three Self‐Expanding Transcatheter Aortic Valve Systems According to the Difference in Shaft Spine

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Accurate bioprosthesis implantation depth during transcatheter aortic valve replacement (TAVR) is crucial for optimal outcomes. Self‐expanding valves (SEVs) have evolved delivery catheter designs, from a double spine shaft in Evolut PRO+ (PRO + ) to single spine in Evolut FX (FX) and non‐spine in Navitor, to improve access ...

Selected properties of phosphorus dendrimers: green approaches to catalysis

Comptes Rendus. Chimie
This review describes the synthesis of polyphosphorhydrazone (PPH) dendrimers, which are highly branched macromolecules, having a phosphorus atom at each branching point. The properties of these PPH dendrimers in the field of catalysis are then described.

The simple production of nonsymmetric quaterpyridines through Kröhnke pyridine synthesis

Beilstein Journal of Organic Chemistry, 2015
Quaterpyridines have been demonstrated to be useful building blocks in metallo-supramolecular chemistry; however, their synthesis requires the preparation of sensitive building blocks.

A Facile Protocol for C(sp2)–C(sp3) Bond Formation Reactions Toward Functionalized E3 Ligase Ligands

ChemMedChem, EarlyView.
A robust C(sp2)–C(sp3) decarboxylative coupling strategy enables access to new CRBN ligands and degraders with improved physicochemical properties. This synthetic approach is expanding the chemical space beyond C(sp2)–N linkages, fine‐tuning proteolysis‐targeting chimera activities and unlocking previously inaccessible degrader chemotypes.

Analysis and Design of ADRC for the LCC-LCC WPT System

IEEE Access
This paper analyzes the dynamic characteristics of wireless power transfer systems based on LCC-LCC topology. By controlling the input current of the primary compensation network, the Active Disturbance Rejection Control (ADRC) Algorithm is used to realize the voltage output of the secondary compensation network indirectly, which improves the dynamic ...

Polyoxometalates Surrounded by Organic Cations or Immobilized on Functionalized Merrifield Resin as Catalysts for Oxidation of β-Myrcene and β-Caryophyllene

Applied Sciences
Polyoxometalates (POMs) surrounded by organic cations and related systems composed of POMs immobilized on functionalized Merrifield resin (MR) were synthesized, characterized and tested as catalysts for the oxidation of two natural terpenes, β-myrcene ...

Testing the proposed link between cosmic rays and cloud cover

, 2008
A decrease in the globally averaged low level cloud cover, deduced from the ISCCP infra red data, as the cosmic ray intensity decreased during the solar cycle 22 was observed by two groups.
