Vectoral air lasing with arbitrary azimuthal angle

Zhichang Wang, Jingsong Gao, Haicheng Mei, Kailu Wang et autres

We demonstrate the generation of nitrogen ions lasing at 391.4 nm of cylindrical vector polarization with an arbitrary azimuthal angle pumped by a femtosecond vector pulse. Moreover, with the injection of an external seed pulse of linear polarization, the significantly amplified lasing …

GGD-SLAM: Monocular 3DGS SLAM Powered by Generalizable Motion Model for Dynamic Environments

Yi Liu, Haoxuan Xu, Hongbo Duan, Keyu Fan et autres

Visual SLAM algorithms achieve significant improvements through the exploration of 3D Gaussian Splatting (3DGS) representations, particularly in generating high-fidelity dense maps. However, they depend on a static environment assumption and experience significant performance degradation in dynamic environments. This paper presents GGD-SLAM, a …

Observation of the Exotic State $π_{1}(1600)$ in $ψ(2S)\rightarrowγχ_{c1},χ_{c1}\rightarrowπ^{+}π^{-}η'$

BESIII Collaboration, M. Ablikim, M. N. Achasov, P. Adlarson et autres

A partial wave analysis of the process $ψ(2S)\rightarrowγχ_{c1}, χ_{c1}\rightarrowπ^+π^-η^{\prime}$ is performed using $(2712.4\pm14.3)\times10^{6}$ $ψ(2S)$ events collected with the BESIII detector. An isovector state with exotic quantum numbers $J^{PC}=1^{-+}$, denoted as $π_{1}(1600)$, is observed for the first time in the charmonium decay of …

HazardArena: Evaluating Semantic Safety in Vision-Language-Action Models

Zixing Chen, Yifeng Gao, Li Wang, Yunhan Zhao et autres

Vision-Language-Action (VLA) models inherit rich world knowledge from vision-language backbones and acquire executable skills via action demonstrations. However, existing evaluations largely focus on action execution success, leaving action policies loosely coupled with visual-linguistic semantics. This decoupling exposes a systematic vulnerability whereby correct …

OVAL: Open-Vocabulary Augmented Memory Model for Lifelong Object Goal Navigation

Jiahua Pei, Yi Liu, Guoping Pan, Yuanhao Jiang et autres

Object Goal Navigation (ObjectNav) refers to an agent navigating to an object in an unseen environment, which is an ability often required in the accomplishment of complex tasks. While existing methods demonstrate proficiency in isolated single object navigation, their limitations emerge in …

RMGS-SLAM: Real-time Multi-sensor Gaussian Splatting SLAM

Dongen Li, Yi Liu, Junqi Liu, Zewen Sun et autres

Achieving real-time Simultaneous Localization and Mapping (SLAM) based on 3D Gaussian splatting (3DGS) in large-scale real-world environments remains challenging, as existing methods still struggle to jointly achieve low-latency pose estimation, continuous 3D Gaussian reconstruction, and long-term global consistency. In this paper, we …

BankerToolBench: Evaluating AI Agents in End-to-End Investment Banking Workflows

Elaine Lau, Markus Dücker, Ronak Chaudhary, Hui Wen Goh et autres

Existing AI benchmarks lack the fidelity to assess economically meaningful progress on professional workflows. To evaluate frontier AI agents in a high-value, labor-intensive profession, we introduce BankerToolBench (BTB): an open-source benchmark of end-to-end analytical workflows routinely performed by junior investment bankers. To …

BESIII Collaboration, M. Ablikim, M. N. Achasov, P. Adlarson et autres

We perform the first amplitude analysis of the singly Cabibbo-suppressed decays $D^+ \to π^+ π^{+(0)} π^{-(0)} η$, using $e^+e^-$ collision data collected with the BESIII detector at the center-of-mass energy of 3.773\,GeV, corresponding to an integrated luminosity of 20.3 $\rm{fb}^{-1}$. The absolute …

Measurement of the branching fractions of $χ_{cJ} \to π^{+}π^{-}π^{0}π^{0}$ via $ψ(3686) \to γχ_{cJ}$

BESIII Collaboration, M. Ablikim, M. N. Achasov, P. Adlarson et autres

Using $(2712.4\pm14.3)\times 10^6$ $ψ(3686)$ events collected with the BESIII detector operating at BEPCII, the branching fractions of $χ_{cJ}\toπ^+π^-π^0π^0$ ($J=0,~1,~2$) are measured via the radiative transition $ψ(3686)\toγχ_{cJ}$. The results are $\mathcal{B}(χ_{c0} \to π^{+}π^{-}π^{0}π^{0}) = (3.10 \pm 0.01 \pm 0.14) \times 10^{-2}$, $\mathcal{B}(χ_{c1} \to …

Safety evaluation of a food enzyme containing endo‐polygalacturonase, pectinesterase and pectin lyase activities from the non‐genetically modified Aspergillus niger strain CCTCC M 2023236

EFSA Panel on Food Enzymes (FEZ), Holger Zorn, José Manuel Barat Baviera, Claudia Bolognesi et autres

Abstract The food enzyme containing endo‐polygalacturonase (1,4‐α‐d‐galacturonan glycanohydrolase; EC 3.2.1.15), pectinesterase (pectin pectylhydrolase; EC 3.1.1.11) and pectin lyase (1,4‐6‐O‐methyl‐α‐d‐galacturonan lyase; EC 4.2.2.10) activities is produced with the non‐genetically modified Aspergillus niger strain CCTCC M 2023236 by Suntaq International Limited. The food enzyme …
