Influencer marketing videos have surged in popularity, yet significant gaps
remain in understanding the relationship between video features and engagement.
This challenge is intensified by the complexities of interpreting unstructured
data....
In this paper, we present a high resolution microwave imaging technique using
a compact and low cost single channel Frequency Modulated Continuous Wave
(FMCW) radar based on Circular Synthetic Aperture Radar (CSAR) technique. We
develop an ...
Robustness of Higher Dimensional Nonlocality against dual noise and
sequential measurements

Quantum Physics
Robustness in the violation of Collins-Linden-Gisin-Masser-Popescu (CGLMP)
inequality is investigated from the dual perspective of noise in measurements
as well as in states. To quantify it, we introduce a quantity called the area
of nonloc...

Recent pulsar timing data reported by the NANOGrav collaboration indicates
the existence of a stochastic gravitational wave (GW) background at a frequency
f∼10−8Hz. We show that a dark sector consisting of a Standard
Model (SM...
Kardar-Parisi-Zhang universality in two-component driven diffusive
models: Symmetry and renormalization group perspectives

We elucidate the universal spatio-temporal scaling properties of the
time-dependent correlation functions in a class of two-component
one-dimensional (1D) driven diffusive system that consists of two coupled
asymmetric exclusion process. By...

We are interested in understanding whether retrieval-based localization
approaches are good enough in the context of self-driving vehicles. Towards
this goal, we introduce Pit30M, a new image and LiDAR dataset with over 30
million frames, w...
Periodic trivial extension algebras and fractionally Calabi-Yau algebras

We study periodicity and twisted periodicity of the trivial extension algebra
T(A) of a finite-dimensional algebra A. Our main results show that
(twisted) periodicity of T(A) is equivalent to A being (twisted)
fractionally Calabi-Ya...

For a 1-parametric family Ek of elliptic curves over Q and a

These notes are designed for those who either plan to work in differential

smooth curves and surfaces -- the main gate to differential geometry. We focus

In many set-identified models, it is difficult to obtain a tractable
characterization of the identified set. Therefore, researchers often rely on
non-sharp identification conditions, and empirical results are often based on
an outer set of ...
