We present a 0.15′′ resolution (21 au) ALMA 870 μm
continuum survey of 25 pointings containing 31 young stellar objects in the
Ophiuchus molecular clouds. Using the dust continuum as a proxy for dust mass
and circumstella...
Formalizing Stack Safety as a Security Property

The term stack safety is used to describe a variety of compiler, run-time,
and hardware mechanisms for protecting stack memory. Unlike "the heap," the
ISA-level stack does not correspond to a single high-level language concept:
different co...

This paper studies identification of the local average and marginal treatment
effects (LATE and MTE) with a misclassified binary treatment variable. We
derive bounds on the (generalized) LATE and exploit its relationship with the
MTE to fur...

Although adaptive optimization algorithms have been successful in many
applications, there are still some mysteries in terms of convergence analysis
that have not been unraveled. This paper provides a novel non-convex analysis
of adaptive o...

Triangle centrality is introduced for finding important vertices in a graph
based on the concentration of triangles surrounding each vertex. It has the
distinct feature of allowing a vertex to be central if it is in many triangles
or none a...

Multiagent Systems
Information about the powers and abilities of acting entities is used to
coordinate their actions in societies, either physical or digital. Yet, the
commonsensical meaning of an acting entity being deemed able to do something is
still missi...

We study the dimension theory of limit sets of iterated function systems
consisting of a countably infinite number of contractions. Our primary focus is
on the intermediate dimensions: a family of dimensions depending on a parameter
$\theta...
Uniform in time weak propagation of chaos on the torus

We address the long time behaviour of weakly interacting diffusive particle
systems on the d-dimensional torus. Our main result is to show that, under
certain regularity conditions, the weak error between the empirical
distribution of the p...
Automorphism and outer automorphism groups of Right-angled Artin groups
are not relatively hyperbolic

We show that the automorphism groups of right-angled Artin groups whose
defining graphs have at least 3 vertices are not relatively hyperbolic. We then
show that the outer automorphism groups are not relatively hyperbolic, if they
are not v...
