Towards AI Search Paradigm
In this paper, we introduce the AI Search Paradigm, a comprehensive blueprint for next-generation search systems capable of emulating human information processing and decision-making. The paradigm employs a modular architecture of four LLM-powered agents (Master, Planner, Executor and Writer) that dynamically adapt to the full spectrum of information needs, from simple factual queries to complex multi-stage reasoning tasks. These agents collaborate dynamically through coordinated workflows to e…

Sharp $L^p$-estimates for wave equation on $ax+b$ groups
Let $G$ be the group $\mathbb{R}_+\ltimes \mathbb{R}^n$ endowed with Riemannian symmetric space metric $d$ and the right Haar measure $\mathrm{d} ρ$ which is of $ax+b$ type, and $L$ be the positive definite distinguished left invariant Laplacian on $G$. Let $u=u(t,\cdot)$ be the solution of $u_{tt}+Lu=0$ with initial conditions $u|_{t=0}=f$ and $u_t|_{t=0}=g$. In this article we show that for a fixed $t \in{\mathbb R}$ and every $1

Integrating Radiomics with Deep Learning Enhances Multiple Sclerosis Lesion Delineation
Background: Accurate lesion segmentation is critical for multiple sclerosis (MS) diagnosis, yet current deep learning approaches face robustness challenges. Aim: This study improves MS lesion segmentation by combining data fusion and deep learning techniques. Materials and Methods: We suggested novel radiomic features (concentration rate and Rényi entropy) to characterize different MS lesion types and fused these with raw imaging data. The study integrated radiomic features with imaging da…

High-efficiency WSe$_2$ photovoltaics enabled by ultra-clean van der Waals contacts
Layered transition metal dichalcogenide semiconductors are interesting for photovoltaics owing to their high solar absorbance and efficient carrier diffusion. Tungsten diselenide (WSe$_2$), in particular, has emerged as a promising solar cell absorber. However, defective metal-semiconductor interfaces have restricted the power conversion efficiency (PCE) to approximately 6%. Here we report WSe$_2$ photovoltaics with a record-high PCE of approximately 11% enabled by ultra-clean indium/gold (In/A…

Stara istuttaa 85 000 kesäkukkaa – Stadin kesäkukkien suunnittelija vaihtuu yli 30 vuoden jälkeen
Helsingin kesä on jälleen täynnä kukkaloistoa. Helsingin kaupungin rakentamispalveluliikelaitos Stara on kasvattanut Kaupunginpuutarhalla 155 000 kausikasvia, joista 94 000 on kesäkukkia. Kaupunkikuvasta tutuiksi tulleita erilaisia suuria kukka-astioita on noin 900, ja ne sijoitetaan ympäri Helsinkiä. Kaiken kaikkiaan Helsingissä kesäkukkia istutetaan yli 180 kohteeseen. Stara vastaa 85 000 kesäkukan istuttamisesta. Istutuksia tehdään Staran hoitamille alueille kukkaryhmiin ja -asti…

Particle Builder -- Learn about the Standard Model while playing against an AI
Particle Builder Online is a web-based education game designed for high school physics students. Students can play against an AI opponent or peers to familiarise themselves with the Standard Model of Particle Physics. The game is aimed at a high school level and tailored to the International Baccalaureate and the Australian Curriculum. Students from four schools in Canberra took pre/post-tests and a survey while completing a lesson where they played Particle Builder. Students' understanding of …

Quenching of single-particle strength inferred from nucleon-removal transfer reactions on $^{15}$C
The difference in the proton and neutron separation energies ($ΔS$) of the weakly bound $^{15}$C ground state is -19.86 MeV, an extreme value. Data from intermediate-energy heavy-ion induced (HI-induced) knockout reactions on nuclei spanning $-20\lesssimΔS\lesssim+20$ MeV, suggest that the degree to which single-particle strength is quenched, $R\mathrm{_{s}}$, has a negative correlation with $ΔS$, decreasing from unity around $-20$~MeV to around 0.2 at $+20$~MeV. For the $^{15}$C ground stat…

Symmetry-protected electronic metastability in an optically driven cuprate ladder
Optically excited quantum materials exhibit nonequilibrium states with remarkable emergent properties, but these phenomena are usually transient, decaying on picosecond timescales and limiting practical applications. Advancing the design and control of nonequilibrium phases requires the development of targeted strategies to achieve long-lived, metastable phases. Here, we report the discovery of symmetry-protected electronic metastability in the model cuprate ladder Sr$_{14}$Cu$_{24}$O$_{41}$. U…
