A Catalyst Designed for the Enantioselective Construction of Methyl- and Alkyl-Substituted Tertiary Stereocenters

2015

Tertiary methyl-substituted stereocenters are present in numerous biologically active natural products. Reported herein is a catalytic enantioselective method for accessing these chiral building blocks using the Mukaiyama-Michael reaction between silyl ketene thioacetals and acrolein. To enable remote enantioface control on the nucleophile, a new iminium catalyst, optimized by three-parameter tuning and by identifying substituent effects on enantioselectivity, was designed. The catalytic process allows rapid access to chiral thioesters, amides, aldehydes, and ketones bearing an α-methyl stereocenter with excellent enantioselectivities, and allowed rapid access to the C4-C13 segment of (-)-b…

Impacts sensoriels et non-sensoriels de la modification d’un attribut d’un produit alimentaire sur ses quantités consommées

2012

Cette recherche examine l’effet de la modification d’un attribut aux effets indésirables (la teneur en alcool du vin) sur la consommation d’un produit. En adoptant une perspective sensorielle, nous testons si la baisse de la quantité de l’attribut du nouveau produit (vin à 9 % d’alcool au lieu de 13,5 %) a une influence physiologique sur les quantités consommées. De même, en adoptant une perspective cognitive, nous examinons si l’information sur la baisse de cet attribut influence également les quantités consommées. Une expérimentation a été mise en œuvre avec deux groupes appariés de 33 individus consommant, soit un vin allégé en alcool (9 % vol.), soit un vin normal (13,5 % vol.), ceci pe…

Exclusive Vector Meson Production at the EIC

2020

We discuss how vector meson production at the future Electron Ion Collider can be used to probe non-linear dynamics in heavy nuclei. Additionally, the potential to study the evolution of proton and nuclear geometries with event-by-event fluctuations is illustrated. nonPeerReviewed

Saturation and forward jets in proton-lead collisions at the LHC

2019

We investigate the forward-jet energy spectrum within the Color Glass Condensate framework at 5 TeV center-of-mass energy. In particular, we focus on the kinematic range covered by the CMS-CASTOR calorimeter. We show that our saturation-model calculations are compatible with the CASTOR measurements and that to optimally reproduce the data, effects of multi-parton interactions need to be included. We predict a significant nuclear suppression - reaching down to 50% at the lowest considered jet energies $E_{\rm jet} \sim 500 \, {\rm GeV}$.

Recent experiments at the JYFLTRAP Penning trap

2020

AbstractThe JYFLTRAP double Penning trap mass spectrometer at the Ion Guide Isotope Separator On-Line (IGISOL) facility offers excellent possibilities for high-precision mass measurements of radioactive ions. Around 400 atomic masses, including around 50 isomeric states, have been measured since JYFLTRAP became operational. JYFLTRAP has also been used as a high-resolution mass separator for decay spectroscopy experiments as well as an ion counter for fission yield studies. In this contribution, an overview of recent activities at the JYFLTRAP Penning trap is given, with a focus on nuclei discussed in the PLATAN2019 meeting.

Innovations in Infant Feeding: Future Challenges and Opportunities in Obesity and Cardiometabolic Disease

2020

The field of nutrition in early life, as an effective tool to prevent and treat chronic diseases, has attracted a large amount of interest over recent years. The vital roles of food products and nutrients on the body’s molecular mechanisms have been demonstrated. The knowledge of the mechanisms and the possibility of controlling them via what we eat has opened up the field of precision nutrition, which aims to set dietary strategies in order to improve health with the greatest effectiveness. However, this objective is achieved only if the genetic profile of individuals and their living conditions are also considered. The relevance of this topic is strengthened considering the importance of …

Analytical pyrolysis of wood and non-wood materials from integrated biorefinery concepts

2019

Wood and non-wood differ with respect to their anatomical, physical, and chemical properties, even among their species, resulting in different behaviors during thermal conversion. Hence, understanding the degradation of these feedstocks by pyrolysis is attractive to establish biorefinery possibilities for renewable resources. Additionally, biomass pretreatment technology plays an important role in many biorefinery processes. Therefore, an approach that integrates such pretreatment with pyrolysis offers an attractive, novel method for improving the end-product spectrum (e.g., enriched either with aliphatic or aromatic constituents). Furthermore, a rapid analytical method for biomass feedstoc…

An Experiment with Facebook as an Advertising Channel for Books and Audiobooks

2016

The paper addresses the problem of using social media to promote innovative products available in online stores. Motivated by the fast development of the audiobook market, on the one hand, and the efficiency of social media marketing, on the other hand, we conducted an experiment with a marketing campaign of books and audiobooks on the most popular social networking site, Facebook, and discussed it in the paper. The goal of the experiment was exploring possible differences in FB users’ reaction to FB advertisements of traditional books and audiobooks. The experiment was implemented by using a real Facebook fanpage of a Polish publishing house having its own online bookstore. Results show so…
