On Sharp Heisenberg Uncertainty Principle and the stability
In this work, we summarize the linearization method to study the Heisenberg Uncertainty Principles, and explain that the same approach can be used to handle the stability problem. As examples of application, combining with spherical harmonic decomposition and the Hardy inequalities, we revise two families of inequalities. We give firstly an affirmative answer in dimension four to Cazacu-Flynn-Lam's conjecture [JFA, 2022] for the sharp Hydrogen Uncertainty Principle, and improve the recent estim…

Uspol, genocide
In case you're wondering whether "political violence" is escalating in the U.S.A. right now, of *course* it is as we move into an era of concentration campus and domestic military deployments. But both domestic genocides and purges as well as political violence targeted at individual prominent figures has been a *constant* throughout American history, from gun duels fought between political rivals to massacres of Native Americans in order to steal their land, to pogroms against Catholics, to literal wars on local Black success and political participation, all dating back before the American Revolution to the beginning of colonization. Thanks to Wikipedia, here's a *small sampling* where I attempted to whittle things down to about one event per decade before recent times.

Weak Nearly $\mathcal S$- and Weak Nearly $\mathcal C$- Manifolds
The recent interest of geometers in the $f$-structures of K. Yano (1961) is motivated by the study of the dynamics of contact foliations, as well as their applications in theoretical physics. Weak metric $f$-structures on a smooth manifold, introduced by of the author and R. Wolak (2022), open a new perspective on the theory of classical structures. In the paper, we define structures of this kind, called weak nearly ${\cal S}$- and weak nearly ${\cal C}$- structures, study their geometry, e.g. …

On the extremal functions of second order uncertainty principles: symmetry and symmetry breaking
This paper focus on the symmetry and symmetry breaking about the second order Hydrogen Uncertainty Principle. \emph{Firstly}, by choosing a suitable test function, we give a negative answer to the conjecture presented by Cazacu, Flynn and Lam in [\emph{J. Funct. Anal.} \textbf{283} (2022), Paper No. 109659, 37 pp] for $N\in\{2,3\}$, and emphasizing the symmetry breaking phenomenon. \emph{Secondly}, we obtain a family of sharp weighted second order Hydrogen Uncertainty Principle, and prove the e…

Across the US, lawmakers and interest groups are stepping up efforts to shield Israel from accountability for war crimes, occupation, and apartheid.
They are doing so by restricting Palestine solidarity advocates’ First Amendment rights to free speech and political boycotts.

Since 2014, dozens of states have adopted similar laws designed to puni…

Improved Approximation Guarantees and Hardness Results for MNL-Driven Product Ranking
In this paper, we address open computational questions regarding the market share ranking problem, recently introduced by Derakhshan et al. (2022). Their modelling framework incorporates the extremely popular Multinomial Logit (MNL) choice model, along with a novel search-based consider-then-choose paradigm. In a nutshell, the authors devised a Pandora's-Box-type search model, where different customer segments sequentially screen through a ranked list of products, one position after the other, …

Spin Constraints on 4U 1630-47 via combined Continuum Fitting and Reflection methods: a comparative study using Frequentist and Bayesian statistics
We present a comprehensive Bayesian spectral analysis of the black hole X-ray binary 4U 1630-47 during its 2022 outburst, using simultaneous \textit{NICER} and \textit{NuSTAR} observations. Using the traditional frequentist approach, we build our model combining reflection spectroscopy with continuum fitting techniques and analyse the data. In the Bayesian framework, we jointly constrain the black hole's spin, mass, inclination, and distance within a unified framework. Employing nested sampling…

On the estimation of solar wind velocity under varying solar activity conditions using Akatsuki measurements
We present an analysis of solar wind dynamics based on Doppler spectral width measurements of X-band radio signals from the Japanese Akatsuki spacecraft. The dataset includes two solar conjunction occultation experiments conducted in 2016 and 2022, capturing the transition from the descending phase of Solar Cycle 24, a period of low solar activity, to the ascending phase of Solar Cycle 25, which exhibited moderate to intense activity. Our study demonstrates the utility of this technique for est…

Does it matter whether a government is "left wing" or "right wing" for economic growth? Using a panel of 113 countries (1995 2022), we combine: (i) the economic ideology of the executive branch (V Dem), (ii) the disaggregated institutional quality of the economic freedom index (Heritage), separating a core institutional block (HN: property rights, government integrity, judicial effectiveness) from a block of liberalization policies (HL: trade/financial openness, regulatory efficiency, size of g…

Oxygen-driven altermagnetic symmetry inducing d-wave superconductivity in the cuprates and nickelates
Since the discovery of cuprate high-Tc superconductivity, numerous theoretical frameworks have been proposed; Anderson's RVB picture (Science 235, 1196-1198, 1987) and U(1) gauge theory (Phys. Rev. Lett. 76, 503-506, 1996) motivate a minimal one-band view that largely integrates out oxygen. By contrast, altermagnetism (Phys. Rev. X 12, 040501, 2022) yields a d-wave-like k-space magnetic texture from alternatingly rotated nonmagnetic cages; La2CuO4 (the parent of a high-Tc cuprate) is a prototyp…
