In recent months, UnitedHealth has targeted traditional journalists and news outlets, a prominent investor, a Texas doctor and activists like Ms. Strause and her father, who complained about a UnitedHealth subsidiary.
In legal letters and court filings, UnitedHealth has invoked last year’s murder of Brian Thompson, the chief executive of the company’s health insurance division,
to argue that intense criticism of the company risks inciting further violence.

UnitedHealth’s Campaign to Quiet Critics
The company has invoked the murder of an executive last year to complain about coverage in news outlets, on streaming services and on social media.

Some talk locally about what the persistent carrier signal is at 7.235 MHz that often (but not always) interferes with one of our local ARES nets. I'm convinced it's the North Korean station that transmits a few hours weekly, in Korean, Chinese and English. My gut feeling is that they transmit a bare carrier when there is no program, to hold the frequency.
Any other ideas? It's a huge signal; I suspect it's not in any way local to California.

Water Demand Forecasting of District Metered Areas through Learned Consumer Representations
Advancements in smart metering technologies have significantly improved the ability to monitor and manage water utilities. In the context of increasing uncertainty due to climate change, securing water resources and supply has emerged as an urgent global issue with extensive socioeconomic ramifications. Hourly consumption data from end-users have yielded substantial insights for projecting demand across regions characterized by diverse consumption patterns. Nevertheless, the prediction of water…

From Kardar-Parisi-Zhang scaling to soliton proliferation in Josephson junction arrays
We propose Josephson junction arrays as realistic platforms for observing nonequilibrium scaling laws characterizing the Kardar-Parisi-Zhang (KPZ) universality class, and space-time soliton proliferation. Focusing on a two-chain ladder geometry, we perform numerical simulations for the roughness function. Together with analytical arguments, our results predict KPZ scaling at intermediate time scales, extending over sufficiently long time scales to be observable, followed by a crossover to the a…

Asymptotic properties of zeros of Riemann zeta function
We try to define the sequence of zeros of the Riemann zeta function by an intrinsic property. Let $(z_k)_{k\in \mathbb{N}}$ be the sequence of nontrivial zeros of $ζ(s)$ with positive imaginary part. We write $z_k= 1/2+iτ_k$ (RH says that these $τ_k$ are all real). Then the sequence $(τ_k)_{k\in \mathbb{N}},$ satisfies the following asymptotic relation \[\sum_{k\in\mathbb{N}}\frac{2x}{x^2+τ_k^2}\simeq \frac12\log\frac{x}{2π}+\sum_{n=1}^\infty \frac{a_n}{x^n},\,\,x\to +\infty\] where $a_{2…

Symmetry and monotonicity of singular solutions for the Hartree equation
In this paper we are concerned with positive singular solutions of the following nonlocal Hartree equation $$-Δu\!=\Big( \int_{\mathbb{R}^N\setminus Γ}\frac{F(u(y))}{|x-y|^μ}dy \Big)f (u(x)), \quad x\in \mathbb{R}^N\setminusΓ,$$ where $F$ is the primitive of $f$ and $Γ$ is the singular set. Under suitable assumptions, we prove that $u$ is symmetric and monotone with respect to the singular set by using moving plane methods. Furthermore, we complement this study by showing the exi…

Over the first months of the second Trump presidency, we have watched the guardrails of democracy come off rapidly in real time.
Mass firings of civil servants,
the dismissal of government watchdogs,
the weaponization of the military against our citizens,
the use of the national budget as a cudgel,
and the dehumanization of immigrants. 
💥Donald Trump and his allies are following what we believe is a similar path as autocrats abroad,
with an American…

Machine Learning-Based Prediction of Speech Arrest During Direct Cortical Stimulation Mapping
Identifying cortical regions critical for speech is essential for safe brain surgery in or near language areas. While Electrical Stimulation Mapping (ESM) remains the clinical gold standard, it is invasive and time-consuming. To address this, we analyzed intracranial electrocorticographic (ECoG) data from 16 participants performing speech tasks and developed machine learning models to directly predict if the brain region underneath each ECoG electrode is critical. Ground truth labels indicating…
