An upper bound for the size of the ideal class monoid

Sungmun Cho · Jungtaek Hong · Yuchan Lee

The ideal class monoid for an order $R$ in a finite field extension $E/F$ of a number field, denoted by $\overline{\mathrm{Cl}}(R)$, is a fundamental object to study in number theory which has useful applications in algebraic geometry and topology. In this paper, we describe an upper bound for $\#\overline{\mathrm{Cl}}...

On the unique solvability of the simultaneous Pell equations x2 − a y2 = 1 and z2 − b x2 = 1

Tobias Hilgart · Volker Ziegler

We consider the simultaneous Pell equations $$x^2 - ay^2 = 1, \qquad z^2 - bx^2 = 1,$$ where $a > b\geq 2$ are positive integers. We describe a procedure which, for any fixed $b$, either confirms that the simultaneous Pell equations have at most one solution in positive integers, or finds all exceptions for which we ha...

Performance of missing data imputation methods for electricity consumption time series data: a comparative study

Kaur, Ramanpreet · Gabrijelčič, Dušan

This publication supports RESONANCE by improving the reliability of smart-meter electricity consumption data used in data-driven energy management. It compares eleven missing-data imputation methods under different missingness rates and gap durations using data from 68 Slovenian households. The results show that linear...

On the existence of integers with at most 3 prime factors between every pair of consecutive squares

Peter J. Campbell

We prove an explicit analogue of Legendre's conjecture for almost primes. Namely, for every integer $n \geq 1$, the interval $(n^2,(n+1)^2)$ contains an integer having at most $3$ prime factors, counted with multiplicity. This improves the previous best result of Dudek and Johnston, who showed that every such interval...

Development of a new recombineering system for Edwardsiella species

Yunjia Deng · Jiayue Sun · Haiyi Ji · Mingjia Qu · y 10 más

Edwardsiella species are important aquaculture pathogens that also cause opportunistic infections in humans, necessitating efficient genome editing tools to study their pathogenesis and develop control strategies. In this study, we identified and characterized six endogenous recombinases pairs from Edwardsiella and its...

Determination of Hilbert modular forms using squarefree coefficients

Rishabh Agnihotri · Krishnarjun Krishnamoorthy

Let $F$ (over $\mathbb{Q}$) be a totally real number field of narrow class number $1$. We generalize a result of Kohnen on the determination of half integral weight modular forms by their Fourier coefficients supported on squarefree (algebraic) integers. We also give a soft proof that infinitely many Fourier coefficien...

Strategies and applications for alleviating carbon catabolite repression

Mengtian Lu · Haoran Ding · Hongyu Zhang · Jianyu Xu · y 6 más

Carbon catabolite repression (CCR) is a widespread regulatory strategy across diverse microorganisms that prioritises the utilisation of preferred carbon sources. In industrial bioprocesses, however, CCR-mediated substrate hierarchy can delay the utilisation of secondary carbon sources in mixed feedstock, thereby exten...

Using selected flexibility resources in the power system to eliminate overloads on high-voltage lines

Paweł Pijarski · Dominik Przepiórka · Wiesława Malska · Petar Sarajčev · y 1 más

With the growing share of distributed energy sources and energy storage, the problem of high-voltage line overloads is becoming one of the key challenges of modern power systems. This paper proposes a method to eliminate transmission line overloads by coordinating power changes among selected generation units, loads, a...

Introducing a Conditional Support Framework: How young residents view the Olympic games

Argyro Elisavet Manoli · Sungkyung Kim · Philipp Wassler

While cost-benefit frameworks have dominated resident support research, they struggle to explain why governance quality increasingly shapes acceptance. This Research Note introduces the conditional support framework (CSF), which treats resident support as a contingent, revisable stance: granted, withheld, or withdrawn...
