We propose a model averaging approach, combined with a partition and matching
method to estimate the conditional average treatment effects under
heteroskedastic error settings. The proposed approach has asymptotic optimality
and consistency...

Industrial Control Systems (ICSs) are widely used in critical infrastructures
that face various cyberattacks causing physical damage. With the increasing
integration of the ICSs and information technology (IT), ensuring the security

Long-term stability and physical consistency are critical properties for
AI-based weather models if they are going to be used for
subseasonal-to-seasonal forecasts or beyond, e.g., climate change projection.
However, current AI-based weathe...

Federated learning (FL) is a popular distributed machine learning (ML)
technique. However, implementation of FL over 5G-and-beyond wireless networks
faces key challenges caused by (i) dynamics of the wireless network conditions
and (ii) the...

We prove resurgence properties for the Borel transform of a formal power
series associated to elements in the Habiro ring that come from radial limits
of partial theta series via strange identities. As an application, we prove a
conjecture ...

We develop the theory of cofinal types of ultrafilters over measurable
cardinals and establish its connections to Galvin's property. We generalize
fundamental results from the countable to the uncountable, but often in
surprisingly strength...

This paper addresses the problem of data-driven computation of controllers
that are correct by design for safety-critical systems and can provably satisfy
(complex) functional requirements. With a focus on continuous-space stochastic
system...

Athermal (i.e. zero-temperature) under-constrained systems are typically
floppy, but they can be rigidified by the application of external strain, which
is theoretically well understood. Here and in the companion paper, we extend
this theor...

Pitman's discrete 2M−X theorem for arbitrary initial laws and
continuous time limits

We discuss Pitman's representation of a Markov process, which serves as a
discrete analog to the Bessel 3D process starting at time 0 from an arbitrary
initial law. This representation involves maxima of lazy simple random walks
and an auxi...
