In the last few years, many advances have been made in the demonstration of
high-average power pulsed THz sources; however, little effort has been made to
study compatible sensitive field-resolved detectors. Here, we investigate
ErAs:InAlGaAs photoconductive receivers optimized for a probe wavelength of
1030 nm and thu... | http://arxiv.org/abs/2308.02590v1 |
We analyze the spin-orbit and Jahn-Teller interactions in $T_d$ symmetry that
are relevant for substitutional transition metal defects in semiconductors. We
apply our theory to the substitutional nickel defect in diamond and compute the
appropriate fine-leve structure and magneto-optical parameters by means of
hybrid d... | http://arxiv.org/abs/2310.08591v1 |
The organization of cells within tissues plays a vital role in various
biological processes, including development and morphogenesis. As a result,
understanding how cells self-organize in tissues has been an active area of
research. In our study, we explore a mechanistic model of cellular organization
that represents c... | http://arxiv.org/abs/2305.03672v2 |
Machine learning (ML) models can underperform on certain population groups
due to choices made during model development and bias inherent in the data. We
categorize sources of discrimination in the ML pipeline into two classes:
aleatoric discrimination, which is inherent in the data distribution, and
epistemic discrimi... | http://arxiv.org/abs/2301.11781v3 |
Pre-trained language models (PLMs) were considered to be able to store
relational knowledge present in the training data. However, some relational
knowledge seems to be discarded unsafely in PLMs due to \textbf{report bias}:
low-frequency relational knowledge might be underexpressed compared to
high-frequency one in PL... | http://arxiv.org/abs/2305.15010v1 |
Let $V$ be an $n$-dimensional inner product space. Assume $G$ is a subgroup
of the symmetric group of degree $m$, and $\lambda$ is an irreducible character
of $G$. Consider the \emph{Cartesian symmetrizer} $C_{\lambda}$ on the
Cartesian space $\times^{m}V$ defined by \[ C_{\lambda} =
\frac{\lambda(1)}{|G|}\sum_{\tau\in... | http://arxiv.org/abs/2304.13990v2 |
Image aesthetics assessment (IAA) aims to estimate the aesthetics of images.
Depending on the content of an image, diverse criteria need to be selected to
assess its aesthetics. Existing works utilize pre-trained vision backbones
based on content knowledge to learn image aesthetics. However, training those
backbones is... | http://arxiv.org/abs/2309.02861v1 |
We consider an interacting quantum dot strongly coupled to two
superconducting leads in a Josephson junction geometry. By defining
symmetry-adapted superpositions of states from the leads, we formulate an
effective Hamiltonian for the strong-hybridisation regime with a single orbital
directly coupled to the dot and thr... | http://arxiv.org/abs/2304.12456v3 |
Automatic dubbing, which generates a corresponding version of the input
speech in another language, could be widely utilized in many real-world
scenarios such as video and game localization. In addition to synthesizing the
translated scripts, automatic dubbing needs to further transfer the speaking
style in the origina... | http://arxiv.org/abs/2305.05203v2 |
Medical vision-and-language pre-training (Med-VLP) has shown promising
improvements on many downstream medical tasks owing to its applicability to
extracting generic representations from medical images and texts. Practically,
there exist two typical types, \textit{i.e.}, the fusion-encoder type and the
dual-encoder typ... | http://arxiv.org/abs/2302.08958v1 |
Understanding the interaction of intense, femtosecond X-ray pulses with heavy
atoms is crucial for gaining insights into the structure and dynamics of
matter. One key aspect of nonlinear light-matter interaction was, so far, not
studied systematically at free-electron lasers -- its dependence on the photon
energy. Usin... | http://arxiv.org/abs/2303.07942v1 |
Modelling spatio-temporal processes on road networks is a task of growing
importance. While significant progress has been made on developing
spatio-temporal graph neural networks (Gnns), existing works are built upon
three assumptions that are not practical on real-world road networks. First,
they assume sensing on eve... | http://arxiv.org/abs/2306.08277v1 |
A model of computation for which reasonable yet still incomplete lower bounds
are known is the read-once branching program. Here variants of complexity
measures successful in the study of read-once branching programs are defined
and studied. Some new or simpler proofs of known bounds are uncovered.
Branching program re... | http://arxiv.org/abs/2305.11276v1 |
