Computer Vision and Pattern Recognition
The intrinsic rotation invariance lies at the core of matching point clouds
with handcrafted descriptors. However, it is widely despised by recent deep
matchers that obtain the rotation invariance extrinsically via data
augmentation. As the...

We show that weakly entangled states can improve communication over a qubit
channel using only separate, interference-free, measurements of individual
photons. We introduce a communication task corresponding to the cryptographic
primitive k...

Superconductivity
Phonon anharmonicity plays a crucial role in determining the stability and
vibrational properties of high-pressure hydrides. Furthermore, strong
anharmonicity can render phonon quasiparticle picture obsolete questioning
standard approaches ...

We discuss the inadequacy of covariances/correlations and other measures in
L2 as relative distance metrics under some conditions. We propose a
computationally simple heuristic to transform a map based on standard principal
component analys...

Mixed-signal neuromorphic processors provide extremely low-power operation
for edge inference workloads, taking advantage of sparse asynchronous
computation within Spiking Neural Networks (SNNs). However, deploying robust
applications to th...
Helicoidal minimal surfaces in the 3-sphere: An approach via spherical

We prove an existence and uniqueness theorem about spherical helicoidal (in
particular, rotational) surfaces with prescribed mean or Gaussian curvature in
terms of a continuous function depending on the distance to its axis. As an
applicati...

We study flow of renormalization group (RG) transformations for the massless
Gross-Neveu model in a non-perturbative formulation. The model is defined on a
d=2 dimensional Euclidean space with a finite volume. The quadratic

Compared with ample visual-text pre-training research, few works explore
audio-text pre-training, mostly due to the lack of sufficient parallel
audio-text data. Most existing methods incorporate the visual modality as a
pivot for audio-text...
