On the Teichmüller stack of homogeneous spaces of SL2(C)
Let Γ be a discrete torsion-free co-compact subgroup of SL2(C). E. Ghys has shown that the Kuranishi space of M = SL2(C)/Γ is given by the germ of the representation variety Hom(Γ, SL2(C)) at the trivial morphism and gave a description of the complex structures given by representations. In this note, we prove that for all admissible representations...
A Test for the Underlying State-Structure of Hidden Markov Models: Partially Observed Capture-Recapture Data
Hidden Markov models (HMMs) are being widely used in the field of ecological modelling, however determining the number of underlying states in an HMM remains a challenge. Here we examine a special case of partially observed capture-recapture models for open populations, where some animals are observed but it is not possible to ascertain their state...
The central parsec of NGC 3783: a rotating broad emission line region, asymmetric hot dust structure, and compact corona...
...
Using VLTI/GRAVITY and SINFONI data, we investigate the sub-pc gas and dust structure around the nearby type 1 AGN hosted by NGC 3783. The K-band coverage of GRAVITY uniquely allows a simultaneous analysis of the size and kinematics of the broad line region (BLR), the size and structure of the near-IR continuum emitting hot dust, and the size of th...

Gravitational wave cosmology with extreme mass-ratio inspirals
The Laser Interferometer Space Antenna (LISA) will open the mHz frequency window of the gravitational wave (GW) landscape. Among all the new GW sources expected to emit in this frequency band, extreme mass-ratio inspirals (EMRIs) constitute a unique laboratory for astrophysics and fundamental physics. Here we show that EMRIs can also be used to ext...
On the rational motivic homotopy category
We study the structure of the rational motivic stable homotopy category over general base schemes. Our first class of results concerns the six operations: we prove absolute purity, stability of constructible objects, and Grothendieck-Verdier duality for SH_Q. Next, we prove that SH_Q is canonically SL-oriented; we compare SH_Q with the category of ...

Can Enhancing Neuronal Activity Improve Myelin Repair in Multiple Sclerosis?
Enhanced neuronal activity in the healthy brain can induce de novo myelination and behavioral changes. As neuronal activity can be achieved using non-invasive measures, it may be of interest to utilize the innate ability of neuronal activity to instruct myelination as a novel strategy for myelin repair in demyelinating disorders such as multiple sc...
Three variations on the linear independence of grouplikes in a coalgebra.
The grouplike elements of a coalgebra over a field are known to be linearly independent over said field. Here we prove three variants of this result. One is a generalization to coalgebras over a commutative ring (in which case the linear independence has to be replaced by a weaker statement). Another is a stronger statement that holds (un-der stron...
