Strengthening Of Existing Structures Using R-UHPFRC: Principles And Conceptual Design

The addition of a layer of strain-hardening UHPFRC to an existing member in reinforced concrete (RC) has proven to be an effective method to increase the structural resistance and durability of concrete structures [1-3]. This paper is intended for structur ...

Yield prediction in parallel homogeneous assembly

Massimo Mastrangeli, Metin Sitti

We investigate the parallel assembly of two-dimensional, geometrically-closed modular target structures out of homogeneous sets of macroscopic components of varying anisotropy. The yield predicted by a chemical reaction network (CRN)-based model is quantit ...

Calculation of the General Number of Imposed Constraints of Kinematic Chains

Jamie Paik, Alexey Fomin

The study provides derivation and application of novel formula for the calculation of general imposed constraints for kinematic chains (including mechanisms and zero-degrees-of-freedom Assur groups) depending on the types of kinematic pairs and numbers of ...

Microfluidic systems for high-throughput and high-content screening using the nematode Caenorhabditis elegans

Martinus Gijs, Thomas Lehnert, Matteo Cornaglia

In a typical high-throughput drug screening (HTS) process, up to millions of chemical compounds are applied to cells cultured in well plates, aiming to find molecules that exhibit a robust dose-response, as evidenced for example by a fluorescence signal. I ...

Beam-beam amplitude detuning with forced oscillations

Xavier Buffat, Tatiana Pieloni, Javier Barranco Garcia, Patrik Gonçalves Jorge

Recently, relations were established between the coefficients of free and forced amplitude detuning polynomial expansions. The forced oscillations were considered only in a single plane. In this paper we extend and generalize previous results by developing ...

Synthesis of Oxazolidin-2-ones by Oxidative Coupling of Isonitriles, Phenyl Vinyl Selenone, and Water

Qian Wang, Jieping Zhu, Thomas Bertrand Pascal Marie Buyck, Delphine Pasche

Reaction of alkyl isocyanides, phenyl vinyl selenone, and water in the presence of a catalytic amount of Cs2CO3 afforded oxazolidin-2-ones in good yields. This unprecedented heteroannulation process created four chemical bonds in a single operation with th ...

Copper-Catalyzed Formal [2+2+1] Heteroannulation of Alkenes, Alkylnitriles, and Water: Method Development and Application to a Total Synthesis of (±)-Sacidumlignan D

Qian Wang, Jieping Zhu, Minh Tu Ha, Claire Chatalova Sazepin

A copper-catalyzed three-component reaction of alkenes, alkylnitriles, and water affords gamma-butyrolactones in good yields. The domino process involves an unprecedented hydroxy-cyanoalkylation of alkenes and subsequent lactonization with the creation of ...
