A practical methodology for $\Lambda$ global polarization extraction in fixed-target experiments
arXiv:2606.04441v1 Announce Type: new Abstract: Non-central heavy-ion collisions generate large orbital angular momentum in the created medium, which leads to polarization of final-state particles via spin-orbit coupling, known as global spin polarization. The observation of significant global polarization of $\Lambda$ hyperon in heavy-ion collisions indicates that the quark-gluon plasma is the most vortical fluid known in nature. Exploring $\Lambda$ global polarization at lower energies is...
Lingo_Research_Group at SemEval-2026 Task 9: Evaluating Prompt Variants for Polarization Detection
arXiv:2606.03334v1 Announce Type: new Abstract: Our submission presented in this paper is for SemEval-2026 Task 9: Multilingual Text Classification Challenge - Polarization Detection and it covers all three subtasks: (1) binary polarization detection, (2) polarization type classification and (3) polarization manifestation identification. We adopt a systematic approach of research on short designed prompts by considering twelve designed prompts that are different in terminology clarity,...
Radiation-induced electron spin polarization in ultrarelativistic kinetic turbulence
Announce Type: new Abstract: Electron spin polarization in radiative plasmas with ultrarelativistic kinetic turbulence under highly magnetized conditions is investigated using particle-in-cell simulations. We observe that a significant spin polarization can be sustained when the leptons undergo energetic photon emission accompanied by spin flips during the nonequilibrium turbulent evolution. By analyzing the time evolution of spatially dependent spin polarization, we identify an...

Electrically Tunable Heliconical Smectic Superstructure in Polar Fluids
arXiv:2512.05517v3 Announce Type: replace-cross Abstract: The ferroelectric nematic (NF) phase and related polar liquid-crystalline phases form a new class of strongly polarized yet fluid soft matter. Well-recognized heliconical ferroelectric phases such as NTBF and SmC_P^H exist, but their electro-optic functionality in smectic systems has been largely unexplored. Here, we report a newly designed single-component achiral molecule exhibiting a hierarchical polar phase sequence:...
Explainable deep-learning detection of microplastic fibers via polarization-resolved holographic microscopy
arXiv:2601.15769v3 Announce Type: replace Abstract: Reliable identification of microplastic fibers is crucial for environmental monitoring but remains analytically challenging. We report an explainable deep-learning framework for classifying microplastic and natural microfibers using polarization-resolved digital holographic microscopy. From multiplexed holograms, the complex Jones matrix of each fiber was reconstructed to extract polarization eigen-parameters describing optical anisotropy.
Strong Polarization and Entropy
arXiv:2606.02567v1 Announce Type: cross Abstract: We show that for any set of $n$ unit vectors $v_1,\ldots,v_n$ in a real Hilbert space and positive numbers $p_1,\ldots,p_n$ satisfying $\sum_j p_j = 1$, there exists a unit vector $u$ such that \[ \sum_{j=1}^n \frac{p_j^2}{\langle v_j, u\rangle^2}\leq 1. This inequality is a weighted version of the strong polarization inequality. As immediate corollaries, it yields a polarization inequality for products of powers of linear functionals and a...
Noisy memory encoding explains negative polarity illusions
arXiv:2606.04340v1 Announce Type: new Abstract: A sentence like "The authors that no critics recommended have ever received acknowledgment for a best-selling novel" is sometimes rated as acceptable even though, strictly speaking, it is ungrammatical because the negative polarity word "ever" is not licensed where it is. This behavioral effect is sometimes called a "negative polarity illusion". Here we propose that the lossy context surprisal theory of Hahn et al.
Beyond 1$\to$N Decoding: Capacity-Aware Rateless Polar Codes for IR-HARQ
Announce Type: new Abstract: This paper introduces a novel framework for polar codes, designed for flexible Incremental Redundancy Hybrid Automatic Repeat Request (IR-HARQ). By generalizing the decoding order beyond the standard 1$\to$N sequence, we enable a capacity-aware scheduling strategy that prioritizes the decoding of reliable subblocks. The framework integrates nested parity-check polar construction and reverse bit-mapping to support continuous and arbitrary transmission lengths $E...
Ryan Clark says NFL players supporting Trump is more polarizing than supporting Obama
Title: Ryan Clark says NFL players supporting Trump is more polarizing than supporting Obama ESPN analyst Ryan Clark says we cannot compare Jaxson Dart's introduction of President Trump to athletes who supported, say, Barack Obama.According to Clark, it's different."Let’s be honest. Who you supported in 2008, 2012 is nowhere near as polarizing as who you support today," Clark said on his podcast."[Trump] has clearly picked a side, [and] standing next to him gives the impression that you have to. Which means you stand in direct opposition to the majority of your teammates," Clark continued.ZERO BS. JUST DAKICH. TAKE THE DON'T @ ME PODCAST ON THE ROAD. DOWNLOAD NOW!Clark acknowledged that Abdul Carter "should have handled things differently," but added that his "disappointment is understandable."Polling data does show that Trump's presidency has, in fact, contributed to the nation's divide. I don't dispute that. However, the same can be said about Obama's presidency.For Clark to describe 2008 and 2012 as if they were not politically divisive times reflects a serious misunderstanding of the era.The same applies to his claim that Trump has "picked a side."All politicians pick a side. That's part
