Mining Voter Behaviour and Confidence: A Rule-Based Analysis of the 2022 U.S. Elections
This study explores the relationship between voter trust and their experiences during elections by applying a rule-based data mining technique to the 2022 Survey of the Performance of American Elections (SPAE). Using the Apriori algorithm and setting parameters to capture meaningful associations (support >= 3%, confidence >= 60%, and lift > 1.5), the analysis revealed a strong connection between demographic attributes and voting-related challenges, such as registration hurdles, accessibility is…

Can Quantum Physics Help Fight Climate Change? A Thematic Analysis of Press Release Narratives
The climate crisis demands innovative solutions and quantum technologies are considered by some a potential solution (Berger et al., 2021; Calvin et al., 2023). The United Nations declared 2025 the International Year of Quantum Science and Technology (United Nations, 2024), focusing on applications for quantum technologies. Quantum technologies, leveraging quantum mechanics, offer unprecedented computational power (Ajagekar & You, 2022) and sensitivity (Schleich et al., 2016) that could revolut…

Prompt Injection 2.0: Hybrid AI Threats
Prompt injection attacks, where malicious input is designed to manipulate AI systems into ignoring their original instructions and following unauthorized commands instead, were first discovered by Preamble, Inc. in May 2022 and responsibly disclosed to OpenAI. Over the last three years, these attacks have continued to pose a critical security threat to LLM-integrated systems. The emergence of agentic AI systems, where LLMs autonomously perform multistep tasks through tools and coordination with…

Extreme values of derivatives of the Dedekind zeta function of a cyclotomic field

Extreme values of derivatives of the Dedekind zeta function of a cyclotomic field
In this paper, we establish a lower bound for the maximum of derivatives of the Dedekind zeta function of a cyclotomic field on the critical line. Employing a double version convolution formula and combing special GCD sums, our result generalizes the work of Bondarenko et al. and Fonga in 2023. We also set a lower bound by the resonance method when the real part is near the critical line, both of the above results refine part of Yang's work in 2022.

Running cars on E-Fuels, made with CO2 from the air and green Hydrogen?🚗⛽🌿⚡
E-Fuels, so the story goes, could allow using existing cars and infrastructure like gas stations. However, E-Fuels are extremely inefficient.
In 2022, Siemens Energy, Porsche, and the Chilean company HIF inaugurated the Haru Oni pilot plant in Chile's windy Magallanes region, which turns CO2 and Hydrogen into Methanol and small amounts of Gasoline. How's it going? 🧵

What's up with the Production of E-Fuels in Chile?
In 2022, Siemens Energy, Porsche, and HIF inaugurated a pilot plant for the production of E-Methanol and E-Gasoline in southern Chile. The Haru Oni plant was intended to be just the beginning — with plans for large-scale production just a few years later. However, it does not look like that will ever happen.

A new Lagrange multiplier approach for constructing structure preserving schemes, III. Bound preserving and energy dissipating
In the third part of this series, we continue to explore the idea of the Lagrange multiplier introduced in the first part [2020, Comput. Methods Appl. Mech. Engr., 391, 114585] and refined in the second part [2022, SIAM J. Numer. Anal., 60, 970-998] to further develop efficient and accurate numerical schemes that preserve the maximum bound principle (MBP) and energy dissipation for solving gradient flows. The proposed framework allows us to begin with any conventional scheme as a predictor step…

Hubble's Multi-Year Search for Exospheres in the TRAPPIST-1 System Reveals Frequent Microflares
Ly-$α$ observations provide a powerful probe of stellar activity and atmospheric escape in exoplanetary systems. We present here an analysis of 104 HST/STIS orbits monitoring the TRAPPIST-1 system between 2017 and 2022, covering 3--5 transits for each of its seven planets. We rule out transit depths $\gtrsim20\%$, which translates into an upper limit on the escape rate of $1064~EO_H$/Gyr for planet b ($1~EO_H$ is the Earth-ocean-equivalent hydrogen content), in agreement with recent claims tha…

Way back in 2022, as the world tried to readjust back to "normal" following COVID - I helped to co-organise a bootcamp with sponsorhop from the @… IASC, @… and a generous dollop of help from @… and @… colleagues.
We gathered 10 senior scientist mentors and 22 students in an old torpedo research station (now used by Roskilde University) for 10 days. It was an extremely intense period but the 4th paper produced by this talented group has just come out.
I consider facilitating #EarlyCareerScientists to work on important science problems an extremely rewarding part of my job, and I'm looking forward to the next one already as part of our PISCO project.
In the mean time, go and read this extremely cool work, collecting together a huge number of radiosonde observations going back to the 1950s over the Arctic Ocean and using them to assess how well CMIP6 models represent lower atmosphere.

A natural and short proof of Lee's conjecture on the Frobenius norm
In 2010, Eun-Young Lee conjectured that if $A,B$ are two $n\times n$ complex matrices and $\left|A\right|, \left|B\right|$ are the absolute values of $A, B$, respectively, then \[ \|A+B\|_F\le \sqrt{\dfrac{1+\sqrt{2}}{2}}\|\left|A\right|+\left|B\right|\|_F, \] where $\|\cdot\|_F$ is the Frobenius norm of matrices. This conjecture was initially proven by Lin and Zhang [J. Math. Anal. Appl. 516 (2022) 126542] by studying inequa…

Update: Progress toward fusion energy breakeven and gain as measured against the Lawson criteria
This paper is an update to our earlier paper ''Progress toward fusion energy breakeven and gain as measured against the Lawson criterion'' [Phys. Plasmas 29, 062103 (2022)]. Plots of Lawson parameter and triple product vs. ion temperature and triple product vs. date achieved are updated with recently published experimental results. A new plot of scientific energy gain vs. date achieved is included. Additionally, notes on new experimental results, clarifications, and a correction are included.

Very interesting talks at the #SolarEclipse Conference - https://www.vvs.be/subsite/sec-2025/programme - in Belgium I am attending online: here is the key result by Luca Quaglia who had reported his work in great detail in the papers https://iopscience.iop.org/article/10.3847/1538-4365/ac1279 (2021), https://www.iota-es.de/JOA/JOA2022_2.pdf#page=3 (2022) and https://www.iota-es.de/JOA/JOA2024_4.pdf#page=3 (2024) already. There seems to be NO way by now to escape the conclusion the the solar - i.e. photospheric - diameter used by many in the past (and various eclipse map calculations sites still today) is too small. So everyone should use Quaglia's free precision tools at https://www.besselianelements.com instead to get the real length of totality at one's observing spot. And when you are observing at the edges of the totality zone the tools will tell you where the actual border is: traditional maps can the off by some margin! 1/n

A Data-Driven Model Predictive Controller to manage epidemics: The case of SARS-CoV-2 in Mauritius
This work investigates the benefits of implementing a systematic approach to social isolation policies during epidemics. We develop a mixed integer data-driven model predictive control (MPC) scheme based on an SIHRD model which is identified from available data. The case of the spread of the SARS-CoV-2 virus (also known as COVID-19) in Mauritius is used as a reference point with data obtained during the period December 2021 to May 2022. The isolation scheme is designed with the control decision…

The prime number theorem over integers of power-free polynomial values
Let $f(x)\in \mathbb{Z}[x]$ be an irreducible polynomial of degree $d\ge 1$. Let $k\ge2$ be an integer. The number of integers $n$ such that $f(n)$ is $k$-free is widely studied in the literature. In principle, one expects that $f(n)$ is $k$-free infinitely often, if $f$ has no fixed $k$-th power divisor. In 2022, Bergelson and Richter established a new dynamical generalization of the prime number theorem (PNT). Inspired by their work, one may expect that this generalization of the PNT also hol…
