SpecCLIP: Aligning and Translating Spectroscopic Measurements for Stars
In recent years, large language models (LLMs) have transformed natural language understanding through vast datasets and large-scale parameterization. Inspired by this success, we present SpecCLIP, a foundation model framework that extends LLM-inspired methodologies to stellar spectral analysis. Stellar spectra, akin to structured language, encode rich physical and chemical information about stars. By training foundation models on large-scale spectral datasets, our goal is to learn robust and in…

Oriented diameter of graphs with diameter $4$ and given maximum edge girth
Let $G$ be a bridgeless graph. We introduce the maximum edge girth of $G$, denoted by $g^*(G)=\max\{l_G(e)\mid e\in E(G)\}$, where $l_G(e)$ is the edge girth of $e$, defined as the length of the shortest cycle containing $e$. Let $F(d,A)$ be the smallest value for which every bridgeless graph $G$ with diameter $d$ and $g^*(G)\in A$ admits a strong orientation $\overrightarrow{G}$ such that the diameter of $\overrightarrow{G}$ is at most $F(d,A)$. Let $f(d)=F(d,A)$, where $A=\{a\in \mathbb{N}\mi…

Neural inference of fluid-structure interactions from sparse off-body measurements
We report a novel physics-informed neural framework for reconstructing unsteady fluid-structure interactions (FSI) from sparse, single-phase observations of the flow. Our approach combines modal surface models with coordinate neural representations of the fluid and solid dynamics, constrained by the fluid's governing equations and an interface condition. Using only off-body Lagrangian particle tracks and a moving-wall boundary condition, the method infers both flow fields and structural motion.…

MAAD: Automate Software Architecture Design through Knowledge-Driven Multi-Agent Collaboration
Software architecture design is a critical, yet inherently complex and knowledge-intensive phase of software development. It requires deep domain expertise, development experience, architectural knowledge, careful trade-offs among competing quality attributes, and the ability to adapt to evolving requirements. Traditionally, this process is time-consuming and labor-intensive, and relies heavily on architects, often resulting in limited design alternatives, especially under the pressures of agil…

MMBench-GUI: Hierarchical Multi-Platform Evaluation Framework for GUI Agents
We introduce MMBench-GUI, a hierarchical benchmark for evaluating GUI automation agents across Windows, macOS, Linux, iOS, Android, and Web platforms. It comprises four levels: GUI Content Understanding, Element Grounding, Task Automation, and Task Collaboration, covering essential skills for GUI agents. In addition, we propose a novel Efficiency-Quality Area (EQA) metric to assess GUI agent execution efficiency in online automation scenarios. Through MMBench-GUI, we identify accurate visual gr…

BaCd2P2: a defect-resistant "GaAs"
BaCd2P2 (BCP) has recently been identified as a promising solar absorber with excellent optoelectronic properties. Here we demonstrate the defect tolerance in BCP by comparing its optoelectronic quality with that of the well studied absorber GaAs. Despite having a low precursor purity, our synthesized BCP samples exhibit a bright band-to-band room-temperature photoluminescence intensity, an implied open-circuit voltage of 1.0 V at AM1.5, and a carrier lifetime of about 300 ns, all higher than t…

IGR J17091-3624: Newly Formed Periodic Dips Detected in the 2025 Outburst
The black hole low-mass X-ray binary (LMXB) candidate IGR J17091-3624 experienced a hard-state-only outburst in 2025. In this paper, we show that IXPE detected a series of intermittent X-ray dips, spanning a total interval of ~1 day. Subsequent observations with NICER, EP, NuSTAR, and Swift reveal that these dips recur with a period of 2.83$\pm$0.07 days and are accompanied by an increase in spectral hardness. This is the first time such quasi-periodic dipping behavior has been observed in this…
