Real-time data processing in the ALICE High Level Trigger at the LHC

2019

At the Large Hadron Collider at CERN in Geneva, Switzerland, atomic nuclei are collided at ultra-relativistic energies. Many final-state particles are produced in each collision and their properties are measured by the ALICE detector. The detector signals induced by the produced particles are digitized leading to data rates that are in excess of 48 GB/$s$. The ALICE High Level Trigger (HLT) system pioneered the use of FPGA- and GPU-based algorithms to reconstruct charged-particle trajectories and reduce the data size in real time. The results of the reconstruction of the collision events, available online, are used for high level data quality and detector-performance monitoring and real-tim…

Desarrollo Directivo en la toma de decisiones estratégicas y cambio estratégico: el Capital Psicológico como variable facilitadora

2019

Con esta Tesis doctoral pretendemos contribuir al desarrollo directivo desde la toma de decisiones estratégicas y el cambio estratégico en las organizaciones, profundizando en como el capital psicológico del equipo directivo y su desarrollo se convierten en una variable facilitadora de este proceso crítico hoy en las empresas y en sus equipos directivos. En entornos hostiles como los actuales, las resistencias al cambio e inercias en la organización y en las decisiones, hacen de la renovación estratégica un proceso realmente complejo. A lo largo de la investigación de la presente Tesis estamos analizando cómo afecta el Capital Psicológico de los directivos de las empresas a sus procesos dec…

La médecine de ville en France : la grande transformation ?

2016

International audience; La récente loi de modernisation du système de santé a fait du tiers-payant le pilier d’une réforme dite “sociale”. Un détour par l’histoire de la médecine libérale montre toutefois l’ambivalence de cette réforme qui va également dans le sens d’une privatisation plus prononcée de la médecine de ville.

Tackling wicked problems in performance management and governance of public health: an empirical analysis of COVID-19 vaccination strategies

2023

PurposePublic health strategies and activities are intrinsically complex. According to the literature, this “wickedness” depends on the different interests and expectations of the stakeholders and the community, the fragmented governance of the related services and the challenges in measuring and assessing public health outcomes. Existent performance measures and management systems for public health are not designed to cope with wickedness since they are mainly focused on inputs and outputs, neglecting broader outcomes because of their long-term impact and the poor accountability of results. This research aims to tackle this shortfall by adopting a dynamic performance management (DPM) appro…

Il «mutamento» delle condizioni patrimoniali e l'eccezione dilatoria ex art. 1461 c.c.

2015

The essay deals with the change in creditworthiness of one party in the reciprocal contracts and it focuses on the dilatory relief regulated by art. 1461 c.c. The author focuses mainly on the concept of change and offers a reinterpretation of the thesis that argues in favor of include in this notion the deterioration in the economic conditions that origins prior to the conclusion of the contract, but that is been without fault ignored by the party seeking the dilatory remedy. There is then the crucial point concerning the foundation of this latter remedy and the dogmatic value of the danger of breach of contract

18:2Δ 9c,12t and 18:2 Δ9t,12c are present in our diet, as result of heat treatment of vegetable oils. A nutritional study was carried out in order to obtain more precise information on the conversion of these two isomers into long chain polyunsaturated fatty acids (PUFA) by rat tissues. This in vivo study performed using rat fed with small quantities of mono trans linoleic acid isomers (0.6% of total energy) showed that 18:2 Δ9c,12t was converted into 20:4 Δ5c,8c,11c,14t while 18:2 Δ9t,12c was only slightly converted into 20:4 Δ5c,8c,11t,14c. Furthermore 18:2 Δ9t,12c was preferentially elongated into 20:2 Δ11t,14c. Each C20 metabolite of these mono trans 18:2 isomers was isolated as methyl …

Cyclodextrins in polymer synthesis: Influence of methylated β-cyclodextrin as host on the free radical copolymerization reactivity ratios of hydropho…

2001

Methylated (β-cyclodextrin (me-β-CD) was used to complex the hydrophobic monomers n-butyl acrylate (1), n-hexyl acrylate (2) and cyclohexyl acrylate (3) yielding the corresponding water soluble host/guest complexes 1a–3a. The complexes were copolymerized in water by free radical mechanism and the reactivity ratios were determined by measuring the monomer consumption by HPLC. The following reactivity ratios were found: copolymerization of 1a and 2a: r1= 1.01 ± 0.01; r2= 1.04 ± 0.01; copolymerization of 3a and 2a: r1= 0.74; r2= 1.28; copolymerization of 3a and 1a: r1= 0.75 ± 0.04; r2= 1.13 ± 0.01. In contrast to that, the copolymerization of the uncomplexed monomers 1–3 in organic medium (DMF…

Isolation and structural characterization of polypeptide antibiotics of the peptaibol class by high-performance liquid chromatography with field deso…

1984

Abstract A number of polypeptide antibiotics of the peptaibol class, i.e., trichotoxin, alamethicin, suzukacillin, hypelcin and paracelsin, have been separated into components and isolated by high-performance liquid chromatography on spherical, porous octadecylsilyl bonded phases. All peptaibols were found to reveal a strong microheterogeneity due to single or multiple amino acid exchange. Most of the closely related and partially isobaric sequence analogue could be resolved using mixed alcohol—water eluents. As demonstrated by the structure analysis of the paracelsins and the main component of trichotoxin A-50, high-performance liquid chromatography with field desorption and fast atom bomb…

Chromatographic peak profile of ionogenic analytes upon elution with unbuffered eluents

1998

Experimental proof of the model was carried out for the separation of benzoic acid on a LiChrospher RP-18 column. The observed chromatographic peak profile coincides with the peak profile predicted by the model. The retention times of the dissociated and non-dissociated species determined by using an appropriate fitting procedure were 2.2 and 4.3 min, respectively. Based on these values, a theoretical peak profile was calculated, demonstrating a close agreement with the experimentally observed peak profile. An unexpectedly large difference was found for the retention times of the dissociated and non-dissociated species calculated by a fitting procedure and those experimentally measured on t…

Free radical scavenging capability, antioxidant activity and chemical constituents of Pyrola incarnata Fisch. leaves

2013

Abstract In the present study, the crude extract and its four fractions of petroleum ether, ethyl acetate, n-butanol, water from Pyrola incarnata Fisch. leaves were prepared and their antioxidant activities were investigated by using four antioxidant assays in vitro. The ethyl acetate fraction showed remarkably strong antioxidant activities on 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging, ABTS radical scavenging, reducing power and β-carotene-linoleic acid bleaching, which were almost comparable to capacities of the positive controls (VC and BHT). The ethyl acetate fraction had the highest total phenolic and total flavonoid contents. Furthermore, Pearson correlation analysis was …
