Observed coupling between air mass history, secondary growth of nucleation mode particles and aerosol pollution levels in Beijing

Atmospheric aerosols have significant effects on the climate and on human health. New particle formation (NPF) is globally an important source of aerosols but its relevance especially towards aerosol mass loadings in highly polluted regions is still contro ...

Microfluidic system based on thermoexpandable polymer for on chip blood coagulation testing

Philippe Renaud, François Bianchi, Lynda Metref

This paper describes a simple system for the actuation of a biological fluid through micro-channels with a thermoactivated polymer actuator. This system is of interest for the development of single-use diagnostic test-strips since the actuation of the samp ...

The DAQ and control system for the CMS Phase-1 pixel detector upgrade

Qian Wang, Varun Sharma, Tian Cheng, Konstantin Androsov, Xin Chen, Davide Di Croce, Albert Perez, Alessandro Caratelli, François Bianchi, Chia-Chun Chen, Simone Scarfì

In 2017 a new pixel detector was installed in the CMS detector. This so-called Phase-1 pixel detector features four barrel layers in the central region and three disks per end in the forward regions. The upgraded pixel detector requires an upgraded data ac ...

Test beam performance of a CBC3-based mini-module for the Phase-2 CMS Outer Tracker before and after neutron irradiation

Varun Sharma, Alexis Kalogeropoulos, Konstantin Androsov, Xin Chen, Rakesh Chawla, Albert Perez, Alessandro Caratelli, François Bianchi, Simone Scarfì

The Large Hadron Collider (LHC) at CERN will undergo major upgrades to increase the instantaneous luminosity up to 5-7.5 x 1034 cm-2s-1. This High Luminosity upgrade of the LHC (HL-LHC) will deliver a total of 3000-4000 fb-1 of proton-proton collisions at ...

On-chip thermopneumatic actuation system for coagulation time measurement

Philippe Renaud, François Bianchi, Lynda Metref

This work reports the demonstration of a thermopneumatic microfluidic actuator used to determine blood coagulation time. In this new system, the detection principle is the obstruction of a microfluidic channel by clotted blood. The sample actuation is done ...

Electroosmotic Flow in Composite Microchannels and Implications in Microcapillary Electrophoresis Systems

Hubert Girault, Patrik Willi Hoffmann, François Bianchi, Frank Rüdiger Wagner

The electroosmotic flow in laminated excimer laser-ablated microchannels has been studied as a function of the depth of the rectangular channels, and particular emphasis has been given to the difference in the ζ-potentials between the lamination layer and ...

Beam test performance of a prototype module with Short Strip ASICs for the CMS HL-LHC tracker upgrade

Qian Wang, Varun Sharma, Tian Cheng, Konstantin Androsov, Jessica Prisciandaro, Xin Chen, Davide Di Croce, Rakesh Chawla, Albert Perez, Alessandro Caratelli, François Bianchi, Simone Scarfì, Chun Xia

The Short Strip ASIC (SSA) is one of the four front-end chips designed for the upgrade of the CMS Outer Tracker for the High Luminosity LHC. Together with the Macro-Pixel ASIC (MPA) it will instrument modules containing a strip and a macro-pixel sensor sta ...

First Evidence for cos 2 beta > 0 and Resolution of the Cabibbo-Kobayashi-Maskawa Quark-Mixing Unitarity Triangle Ambiguity

Mingkui Wang, Olivier Schneider, Chao Wang, Yiming Li, Liang Sun, Sun Hee Kim, Songmei Wu, Tara Nanut, Jun Yong Kim, Greig Alan Cowan, Roberto Gargiani, Marilisa Neri, Alexandra Bondarenko, François Bianchi, Seyed Sina Mirrazavi Salehian, Aaron James Rossini, Arnaud Michel Gelb, Yong Chan Choi, Gaétan Charles Antoine Giriat, Martin Lubej, Taoufiq Harach, Wondwossen Wubie Eshetu, Mithilesh Nayak, Johannes Julius Thomas Marinus Swartjes, Jiayun Shen, Lorenzo Vitale, Amaury Robert Dame, Armend Gazmeno Hati, Amro Ahmed Hussien Ahmed

We present first evidence that the cosine of the CP-violating weak phase 2 beta is positive, and hence exclude trigonometric multifold solutions of the Cabibbo-Kobayashi-Maskawa (CKM) Unitarity Triangle using a time-dependent Dalitz plot analysis of B-0 -> ...
