Tracing the formation of the Milky Way through ultra metal-poor stars

Pascale Jablonka, Nicolas Lawrence Etienne Longeard

We use Gaia DR2 astrometric and photometric data, published radial velocities and MESA models to infer distances, orbits, surface gravities, and effective temperatures for all ultra metal-poor stars ([Fe/H] < -4.0 dex) available in the literature. Assuming ...

Sequential catalysis enables enhanced C-C coupling towards multi-carbon alkenes and alcohols in carbon dioxide reduction: a study on bifunctional Cu/Au electrocatalysts

Michael Graetzel, Shaik Mohammed Zakeeruddin, Jing Gao, Dan Ren

Electrochemical reduction of carbon dioxide (CO2) to multi-carbon products such as ethylene, ethanol and n-propanol offers a promising path for utilization of excessive CO2 and energy storage. Oxide-derived Cu electrodes are among the best electrocatalysts ...

Modeling the kinetics of the main peak and later age of alite hydration

Alexandre Reda Constantin William Caleb Ouzia

The aim of this thesis is to understand the mechanisms underlying the main hydration peak and later ages of alite hydration; it proposes new mechanistic models for these two stages. Alite is the main constituent of Portland Cement (PC), and is responsible ...

The metalloprotease ADAMTS4 generates N-truncated A4-x species and marks oligodendrocytes as a source of amyloidogenic peptides in Alzheimer's disease

Patrick Fraering, Mitko Dimitrov, Hermeto Gerber, Sandra Lehmann

Brain accumulation and aggregation of amyloid- (A) peptides is a critical step in the pathogenesis of Alzheimer's disease (AD). Full-length A peptides (mainly A1-40 and A1-42) are produced through sequential proteolytic cleavage of the amyloid precursor pr ...

Theory for the density of interacting quasilocalized modes in amorphous solids

Matthieu Wyart, Thomas Willem Jan de Geus, Wencheng Ji, Marko Popovic

Quasilocalized modes appear in the vibrational spectrum of amorphous solids at low frequency. Though never formalized, these modes are believed to have a close relationship with other important local excitations, including shear transformations and two-lev ...

Effects of collisionality and T e /T i on fluctuations in positive and negative δ tokamak plasmas

Olivier Sauter, Ambrogio Fasoli, Stefano Coda, Stephan Brunner, Laurie Porte, Gabriele Merlo, Matteo Fontana, Ajay Chandrarajan Jayalekshmi

The effects of negative triangularity () on confinement and fluctuations in plasmas covering a large range of parameters were investigated on the tokamak à configuration variable (TCV). The conditions explored in this paper include discharges where neutral ...

On the Metal Contents of Ocean Floor Nodules, Crusts and Massive Sulphides and a Preliminary Assessment of the Extractable Amounts

The metal contents of ocean floor nodules, crusts and massive sulphides was estimated and an assessment of their commercial extractability were conducted. The metals considered were iron, manganese, copper, nickel, cobalt, molybdenum, platinum, gold and si ...

Orders that are étale-locally isomorphic

Eva Bayer Fluckiger, Mathieu Huruguen

Let R be a semilocal Dedekind domain with fraction field F. It is shown that two hereditary R-orders in central simple F-algebras that become isomorphic after tensoring with F and with some faithfully flat étale R-algebra are isomorphic. On the other hand, ...

Spatio-temporal structure of single neuron subthalamic activity identifies DBS target for anesthetized Tourette syndrome patients

Silvestro Micera, Matteo Vissani

Objective. Deep brain stimulation (DBS) of basal ganglia effectively tackles motor symptoms of movement disorders such as Tourette syndrome (TS). The precise location of target stimulation site determines the range of clinical outcome in DBS patients, and ...
