"It’s also a smart reply to the recent 'abundance' arguments made by many in the party’s establishment. Yes, we need to build out transit and increase housing development, but the public sector should do those things. A strong defense of the public sector against privatization, and a willingness to push for its expansion instead of opting for 'market-based solutions,' is an essential part of what it means to be a democratic socialist"

The Democratic Socialist Core to Zohran Mamdani’s Campaign
At a time when much of the left is in retreat or ducking for cover, Zohran Mamdani’s mayoral campaign is championing democratic socialist politics and raising expectations.

Electromagnetic probes revealing the inner structure of the $Λ_c(2940)$
The $Λ_c(2940)$, an open-charm baryon discovered in 2006, has sparked interest due to its ``low mass puzzle'', paralleling the $X(3872)$ in the charmoniumlike sector. Both states challenge conventional hadronic interpretations, with the $X(3872)$ understood as a $D^*\bar{D}$ molecular state and the $Λ_c(2940)$ hypothesized as a $D^*N$ molecular state. This work investigates the radiative decay modes $Λ_c(2940) \to Λ_c(2286)γ$, $Λ_c(2940) \to Λ_c(2595)γ$, and $Λ_c(2940) \to Λ_c(2765)γ…

So this is how it ends, not with a bang, but with six fingers holding a bacon icecream cone and only two r's in our strawberries.

Why is the volatility of single stocks so much rougher than that of the S&P500?
The Nested factor model was introduced by Chicheportiche et al. to represent non-linear correlations between stocks. Stock returns are explained by a standard factor model, but the (log)-volatilities of factors and residuals are themselves decomposed into factor modes, with a common dominant volatility mode affecting both market and sector factors but also residuals. Here, we consider the case of a single factor where the only dominant log-volatility mode is rough, with a Hurst exponent $H \sim…

Public Acceptance of Cybernetic Avatars in the service sector: Evidence from a Large-Scale Survey in Dubai
Cybernetic avatars are hybrid interaction robots or digital representations that combine autonomous capabilities with teleoperated control. This study investigates the acceptance of cybernetic avatars in the highly multicultural society of Dubai, with particular emphasis on robotic avatars for customer service. Specifically, we explore how acceptance varies as a function of robot appearance (e.g., android, robotic-looking, cartoonish), deployment settings (e.g., shopping malls, hotels, hospital…

Comments on Class S(YK)
We present a DSSYK-like interpretation of the Schur half-indices of $\mathcal{N}=2$ $SU(2)$ gauge theories with matter, in the presence of fundamental Wilson lines. The Schur half-indices of these theories can be understood as transition amplitudes in a non-vacuum sector of ordinary DSSYK. In the language of chord diagrams, the half-indices are obtained by summing over diagrams with special segments, which correspond to coherent states of the $q$-oscillator algebra. In addition, we show that th…

The Stablecoin Discount: Evidence of Tether's U.S. Treasury Bill Market Share in Lowering Yields
Stablecoins represent a critical bridge between cryptocurrency and traditional finance, with Tether (USDT) dominating the sector as the largest stablecoin by market capitalization. By Q1 2025, Tether directly held approximately $98.5 billion in U.S. Treasury bills, representing 1.6% of all outstanding Treasury bills, making it one of the largest non-sovereign buyers in this crucial asset class, on par with nation-state-level investors. This paper investigates how Tether's market share of U.S. T…
