A judge in Michigan dismissed the felony charges against a slate of electors who falsely signed on to documents claiming Donald Trump won the 2020 election
in the latest blow to efforts to hold the president and his allies accountable for attempting to overturn the results of the White House race he lost to Joe Biden.
Sixteen people were initially charged with eight felonies each related to forgery and conspiracy by the Democratic attorney general, Dana Nessel, in 2023,

we drove to negaunee ("iron city") and shopped a little. (i bought a 1963 henry mancini record and a 1930 pamphlet, "how to throw a party.")
negaunee has some cool old buildings.

The photo shows the Vista Theater in Negaunee, Michigan. The theater, constructed in 1925, is a three-story building made of yellow-buff brick. It was listed on the National Register of Historic Places in 2005. The building was condemned in 2020 after a roof collapse, but restoration efforts have been underway since then.

The photo shows the facade of a brick building that houses a business named Tino's Bar & Pizza. The building has a prominent arched window on the second floor and a green, decorative cornice at the top. The ground floor features two large windows displaying the business name and a central entrance. The text on the windows indicates that the business is "Family owned and operated since 1982". The image was taken on a clear, sunny day.

The photo shows a historic, three-story red brick building with a prominent turret, located at 101 S Pioneer Avenue in Negaunee, MI. The building features arched windows and a dark-colored roof. The property was originally built as a home and later converted to office space.

The photo shows the Negaunee City Hall, a historic two-story building in Negaunee, Michigan, with a prominent clock tower.

Architecture: The building, erected in 1915, is constructed with alternating courses of white pressed brick and grayish-white limestone, featuring terra-cotta detailing.

Clock Tower: A ninety-four-foot-high clock tower rises above the main entrance.

Location: The building is located in Negaunee, Michigan. The words "CITY HALL" are visible above the main entrance.

Hybrid GCN-GRU Model for Anomaly Detection in Cryptocurrency Transactions
Blockchain transaction networks are complex, with evolving temporal patterns and inter-node relationships. To detect illicit activities, we propose a hybrid GCN-GRU model that captures both structural and sequential features. Using real Bitcoin transaction data (2020-2024), our model achieved 0.9470 Accuracy and 0.9807 AUC-ROC, outperforming all baselines.

"Love must have compassion and empathy at its beck and call.
As uncomfortable as truth can so often be, it remains true without any believers, without any champions arguing its case.
Pain is, heartrendingly, unavoidable. Misery is an option we can choose willfully by thinking we know everything and have nothing to learn."

What began as a silent infiltration into one of the world’s largest cryptocurrency mining pools has now been confirmed as
the biggest crypto theft in history.
The LuBian mining pool, once a dominant force in the Bitcoin network, quietly lost over 127,000 Bitcoins in 2020.
The breach was only uncovered in 2025 by Arkham Intelligence, revealing a staggering $14.5 billion worth of stolen assets that had remained untouched and undetected for half a decade

The biggest heist of all time involved over $14 billion of crypto being stolen - and it went undetected for five years

Shortly thereafter, the app was made available for download in the app stores. However, the first version of the DPIA had significant weaknesses, as this paper argues. However since then, the quality of the official DPIA increased immensely due to interventions and interactions such as an alternative DPIA produced by external experts and extensive public disc…

Automated Discovery of Test Oracles for Database Management Systems Using LLMs
Since 2020, automated testing for Database Management Systems (DBMSs) has flourished, uncovering hundreds of bugs in widely-used systems. A cornerstone of these techniques is test oracle, which typically implements a mechanism to generate equivalent query pairs, thereby identifying bugs by checking the consistency between their results. However, while applying these oracles can be automated, their design remains a fundamentally manual endeavor. This paper explores the use of large language mode…

Superpolynomial convergence in the Riemann Rearrangement Theorem
Let $x \in \mathbb{R}$ be arbitrary and consider the `greedy' approximation of $x$ by signed harmonic sums: given $a_n = \sum_{k \leq n} \varepsilon_k/k$ with $\varepsilon_k \in \left\{-1,1\right\}$, we set $\varepsilon_{n+1} = 1$ if $a_n \leq x$ and $\varepsilon_{n+1} = -1$ otherwise. Bettin-Molteni-Sanna showed (Adv.

Contact binary asteroid (153201) 2000 WO107: rotation, shape model, and density
We combine different methods to investigate the rotation, determine the shape and estimate the density of near-Earth asteroid (153201) 2000 WO$_{107}$. We carried out photometric observations of the asteroid during the 2020 apparition. Then we created a program able to simulate the lightcurves, and used it within a Markov chain Monte Carlo (MCMC) algorithm to reconstruct the asteroid shape model from the observational data. The Goldstone radar observations of the asteroid were used as an additi…

On the common index jump theorem and further developments
In [LZ02], Long and Zhu established originally the common index jump theorem (CIJT) for symplectic paths in 2002, which was later generalized to its enhanced version (ECIJT) by Duan, Long and Wang in [DLW16] in 2016. Started from [GGM18] of 2018 and [GG20] of 2020, and finally in [CGG24] of 2024, a similar index theorem was obtained, i.e., Theorem 3.3 of [CGG24], which was called the index recurrence theorem there. In this short note, we give detailed proofs to show that the first 4 assertions …

Artificial Intelligence for CRISPR Guide RNA Design: Explainable Models and Off-Target Safety
CRISPR-based genome editing has revolutionized biotechnology, yet optimizing guide RNA (gRNA) design for efficiency and safety remains a critical challenge. Recent advances (2020--2025, updated to reflect current year if needed) demonstrate that artificial intelligence (AI), especially deep learning, can markedly improve the prediction of gRNA on-target activity and identify off-target risks. In parallel, emerging explainable AI (XAI) techniques are beginning to illuminate the black-box nature …

Global Drought Escalation Since 2014: Multivariate Insights for Ecosystem Resilience and Water Security
How is climate change altering the global patterns, frequency, and intensity of drought? To investigate this, we analyzed global drought events from 2000-2020 using a composite of hydrological indices (Σ(ET-P), SSMI, and GRACE-DSI). Our results reveal that near-normal to severe droughts became increasingly widespread after 2014. Unexpectedly, extreme, 100-year return period droughts occurred not only in semi-arid zones but also in high latitude and typically wet regions. The frequency of these…

Scaling and Population Loss in Mexican Urban Centres
Despite its pervasive implications, many cities around the world continue to expand in a fragmented and horizontal manner. Here, we analyse the complex dynamics of urban growth across 69 metropolitan areas in Mexico, using census data from 1990 to 2020, and develop a model of urban form change that considers changes in population size, density, and spatial configuration. We employ a radial probability density function and the urban expansion factor to create a framework for comparing urban expa…

Unintended Consequences of Early Driving Access: Evidence from Graduated Driver Licensing Policies and Adolescent Health Outcomes
Graduated driver licensing systems effectively reduce adolescent traffic fatalities but create unintended health consequences. Using state-level variation in licensing policies from 1999-2020 and difference-in-differences analysis, we provide the first causal evidence that early driving access generates significant health risks for female adolescents aged 15-19. States allowing learner's permits before age 16 experienced sharp increases in drug-related mortality (+1.331 per 100,000, p<0.001) an…

Stability and Superconductivity of Ternary Polyhydrides
We review five years of experimental and theoretical attempts (2020-2025) to enhance the superconducting critical temperature ($\textit{T$_c$}$) of hydrogen-rich compounds by alloying binary superhydrides with additional elements. Despite predictions of higher $\textit{T$_c$}$ in ternary systems such as La-Y-H, La-Ce-H, and Ca-Mg-H, experiments consistently show that the maximum $\textit{T$_c$}$ in disordered ternary superhydrides does not exceed that of the best binary parent hydrides within e…

Reconstruction in the Calderón problem on a fixed partition from finite and partial boundary data
This short note modifies a reconstruction method by the author (Comm. PDE, 45(9):1118--1133, 2020), for reconstructing piecewise constant conductivities in the Calderón problem (electrical impedance tomography). In the former paper, a layering assumption and the local Neumann-to-Dirichlet map was needed since the piecewise constant partitioning also was assumed unknown. Here I show how to modify the method in case the partitioning is known, for general piecewise constant conductivities and onl…

A Caveat on Metrizing Convergence in Distribution on Hilbert Spaces
We consider Sobolev-type distances on probability measures over separable Hilbert spaces involving the Schatten-$p$ norms, which include as special cases a distance first introduced by Bourguin and Campese (2020) when $p=2$, and a distance introduced by Giné and Leon (1980) when $p=\infty$. Our analysis shows that, unless $p=\infty$, these distances fail to metrize convergence in distribution in infinite dimensions. This clarifies several inconsistencies and misconceptions in the recent litera…

The behavior of the bright red supergiant, Betelgeuse, is described with results principally from the past 6 years. The review includes imaging, photometry, and spectroscopy to record the Great Dimming of 2019--2020. This event was followed by a slow ongoing recovery from the massive surface mass ejection after which the stellar characteristics changed. Theoretical simulations address the cause of this episodic mass ejection and the optical Dimming. Recent publications evaluating the perplexing…

The impact of Alfvenic shear flow on magnetic reconnection and turbulence
Magnetic reconnection is a fundamental and omnipresent energy conversion process in plasma physics. Novel observations of fields and particles from Parker Solar Probe (PSP) have shown the absence of reconnection in a large number of current sheets in the near-Sun solar wind. Using near-Sun observations from PSP Encounters 4 to 11 (Jan 2020 to March 2022), we investigate whether reconnection onset might be suppressed by velocity shear. We compare estimates of the tearing mode growth rate in the …

Optimal Portfolio Construction -- A Reinforcement Learning Embedded Bayesian Hierarchical Risk Parity (RL-BHRP) Approach
We propose a two-level, learning-based portfolio method (RL-BHRP) that spreads risk across sectors and stocks, and adjusts exposures as market conditions change. Using U.S. Equities from 2012 to mid-2025, we design the model using 2012 to 2019 data, and evaluate it out-of-sample from 2020 to 2025 against a sector index built from exchange-traded funds and a static risk-balanced portfolio. Over the test window, the adaptive portfolio compounds wealth by approximately 120 percent, compared with 1…

Digital welfare fraud detection and the Dutch SyRI judgment
In 2020, a Dutch court passed judgment in a case about a digital welfare fraud detection system called Systeem Risico Indicatie (SyRI). The court ruled that the SyRI legislation is unlawful because it does not comply with the right to privacy under the European Convention of Human Rights. In this article we analyse the judgment and its implications. This ruling is one of first in which a court has invalidated a welfare fraud detection system for breaching the right to privacy.
