In Video Instance Segmentation (VIS), classification, segmentation, and tracking objectives are jointly evaluated, but their individual contributions to performance loss remain opaque. We introduce a diagnostic framework that formulates identity and class assignment as an Integer Linear Program (ILP), yielding a model-...

The aim of this article is to study the dynamics of random products of weighted shifts on a separable Fréchet sequence space. That is, given a measure-preserving dynamical system $(Ω, \mathcal{F}, μ, τ)$, a Fréchet sequence space $X$ with a basis $(e_n)_{n \geq 0}$, and a strongly measurable map $T : Ω\to \mathcal{B}(X...
White and turquoise Ca-antimonate tesserae from Noheda (Spain) were characterized using LA-ICP-MS, XRD, SEM, and XANES spectroscopy to investigate their composition, crystalline phases, and opacification mechanisms. White tesserae contain a single Ca-antimonate phase (CaSb 2 O 6 or Ca 2 Sb 2 O 7 ), controlled by MgO co...

In this work, selective pressure was applied in E. coli to enrich the population expressing recombinant proteins and suppress the emergence of low-expression phenotypes. To this end, plasmids were constructed containing two reporter genes, a degradable green fluorescent protein (GFP) and a stable red fluorescent protei...

We propose a non-parametric frequency-domain method to identify small-signal $dq$-asymmetric grid impedances, over a wide frequency band, using grid-connected converters. Existing identification methods are faced with significant trade-offs: e.g., passive approaches rely on ambient harmonics and rare grid events and th...

This paper contains two main results. First, we provide combinatorial branching rules for $\mathrm{GL}_n \downarrow \mathrm{O}_n$ and $\mathrm{GL}_{2n} \downarrow \mathrm{Sp}_{2n}$ extending the Littlewood restriction rules. Second, we use these branching rules and the combinatorics of $\mathrm{GL}_n$-crystals to deriv...

Aggressive behavior is a critical issue affecting health and survival in aquaculture animals; however, the molecular mechanism of aggression in reptiles has not been fully understood. Using the Chinese softshell turtle (Pelodiscus sinensis) as a model, we established a turtle model of reactive aggression using the intr...
We show variants of the genus inequality for the irreducible components of the special fiber of an arithmetic curve over a henselian discrete valuation ring of residue characteristic zero that take into account the non-existence of rational, respectively real points on the the components. We then apply this inequality...

We develop a mathematical modeling framework to address the challenge in launching an effective staged vaccination campaign during a typical viral infection season to avoid an overwhelmed healthcare system for the entire season. Using the COVID-19 pandemic following its acute phase as a motivating example, our model ta...

The red yeast Rhodotorula toruloides is a robust lipid producer, and its biotechnology applications have been expanded through genetic engineering based on the non-homologous end joining (NHEJ) pathway. As the NHEJ pathway leads to random integration, it remains laborious in phenotypic assessment and challenging for ra...
