Lucky Lucky SHD 400 (FF) English Alt Text: A black-and-white image of a tall metal pole with multiple loudspeakers facing different directions, designed for wide-area sound coverage. A floodlight is mounted lower on the pole. The sky is partly cloudy. The setup suggests use for public announcements or emergency alerts. The monochrome tone gives the image a vintage or documentary feel. 中文替代文字： 黑白照片显示一个高大的金属杆，上面安装了多个朝不同方向的扩音器，用于广域广播。杆子下方还有一个泛光灯。天空部分多云。此结构可能用于公共广播或紧急警报。黑白色调为画面增添了复古或纪录片风格。
Lucky Lucky SHD 400 (FF) English Alt Text: A black-and-white photo of a quiet train yard. Curved train tracks lead into the distance. A stationary train car sits on the right. A tall metal tower with a light or signal stands in the center. Small buildings and sheds line the middle ground, with tall trees and a multi-story building in the background. The scene feels still and possibly abandoned. 中文替代文字： 黑白照片展示一个安静的铁路场站。弯曲的铁轨延伸至远方，右侧停着一节列车车厢。中央有一座带灯或信号的高金属塔。中景是几座小建筑和棚屋，背景是高大的树木和一栋多层建筑。画面静谧，可能是废…
Lucky Lucky SHD 400 (FF) English Alt Text: A black-and-white image of an outdoor urban area. Several motorcycles and scooters are parked in the foreground, some covered with protective sheets. To the right is a building with a tiled roof. Trees and a tall building are visible in the background. The sky is cloudy, and faint vertical lines suggest film damage or scanning artifacts. 中文替代文字： 黑白照片描绘一个户外城市场景。前景停放着几辆摩托车和电动车，有些覆盖着防护布。右侧是一栋带瓦屋顶的建筑。背景有树木和一栋高楼。天空多云，画面上有些垂直线条，可能是胶片损伤或扫描痕迹。

Metrics vs Surveys: Can Quantitative Measures Replace Human Surveys in Social Robot Navigation? A Correlation Analysis
Social, also called human-aware, navigation is a key challenge for the integration of mobile robots into human environments. The evaluation of such systems is complex, as factors such as comfort, safety, and legibility must be considered. Human-centered assessments, typically conducted through surveys, provide reliable insights but are costly, resource-intensive, and difficult to reproduce or compare across systems. Alternatively, numerical social navigation metrics are easy to compute and faci…

Optimal Quantum $(r,\delta)$-Locally Repairable Codes From Matrix-Product Codes
Meng Cao, Kun Zhou
arxiv.org/abs/2508.03597 arxiv.org/pdf/2…

Optimal Quantum $(r,δ)$-Locally Repairable Codes From Matrix-Product Codes
This paper studies optimal quantum $(r,δ)$-LRCs from matrix-product (MP) codes. We establish a necessary and sufficient condition for an MP code to be an optimal $(r,δ)$-LRC. Based on this, we present a characterization for optimal quantum $(r,δ)$-LRCs from MP codes with nested constituent codes, and also study optimal quantum $(r,δ)$-LRCs constructed from MP codes with non-nested constituent codes. Through Hermitian dual-containing and Euclidean dual-containing MP codes, we present five in…

Using Gauge Covariant Lie Derivatives in Einstein-Cartan and Metric Teleparallel Theories of Gravity
A procedure to determine the initial ansatz for the co-frame and spin connection characterizing a Riemann-Cartan geometry respecting a given group of continuous symmetries is illustrated. Given a particular group of symmetries and assuming an orthonormal gauge we can determine the co-frame and corresponding spin connection having this symmetry group by employing an gauge covariant Lie derivative. This gauge covariant Lie derivative when applied to the metric and co-frame determines the values o…

On-shell Matrix Elements of the EMT Trace in Gauge Theories and Heavy Quark Masses
Long Chen, Zhe Li, Marco Niggetiedt
arxiv.org/abs/2509.03580

On-shell Matrix Elements of the EMT Trace in Gauge Theories and Heavy Quark Masses
We present a novel diagrammatic proof of the identity between the forward matrix element of the energy-momentum-tensor (EMT) trace operator over a single particle's on-shell state and its perturbative pole mass to any loop orders in perturbative gauge theories (with gauge bosons and fermions), without appealing to any pre-laid operator renormalization conditions or Ward identities. The proof is based on the equation of mass-dimensional analysis in dimensional regularization, the topological pro…

Manifestations of Empathy in Software Engineering: How, Why, and When It Matters

Manifestations of Empathy in Software Engineering: How, Why, and When It Matters
Empathy plays a crucial role in software engineering (SE), influencing collaboration, communication, and decision-making. While prior research has highlighted the importance of empathy in SE, there is limited understanding of how empathy manifests in SE practice, what motivates SE practitioners to demonstrate empathy, and the factors that influence empathy in SE work. Our study explores these aspects through 22 interviews and a large scale survey with 116 software practitioners. Our findings pr…

Lucky Lucky SHD 400 (FF) 🔹 English Alt Text A cityscape viewed from an elevated position. High-rise buildings and residential blocks stretch across the frame. The right side is clear, showing streets, trees, and vehicles. The left side is obscured by bright overexposure, partially concealing some buildings. The architectural mix of modern and older styles reflects urban density. The black-and-white tone adds drama and nostalgia to the scene. 🔹 中文替代文字 从高处俯瞰城市景观。画面右侧清晰，展示了高楼、街道、车辆和树木。左侧因强光曝光而…
Lucky Lucky SHD 400 (FF) 🔹 English Alt Text A quiet sidewalk scene with trees lining the left side, casting shade. On the right, closed storefronts with metal shutters and signage in Chinese, including “百家商店” (Hundred Family Store), suggest a general goods shop. Tactile paving runs along the brick sidewalk for visually impaired pedestrians. A circular traffic sign and a rectangular street sign are visible. The atmosphere is calm and subdued, enhanced by the black-and-white tones. 🔹 中文替代文字 一…
Lucky Lucky SHD 400 (FF) 🔹 English Alt Text A narrow tiled street lined with market stalls and small shops. On the right, baskets of fruit—likely apples—are placed on the ground in front of awnings and signs with Chinese characters. On the left, motorcycles and bicycles are parked. Tall buildings with balconies and air conditioners loom above, and trees line both sides. The scene suggests a mixed-use neighborhood, blending residential and commercial life. The monochrome palette adds a nostalg…
Lucky Lucky SHD 400 (FF) 🔹 English Alt Text A gritty urban alleyway used for construction storage. A large mound of sand or gravel sits in the center, surrounded by stacked cement bags and bricks. The area is enclosed by buildings with visible air conditioning units and tangled electrical wires. Chinese signs are present: one reads “水泥沙子” (cement and sand), another advertises clothing alterations. Metal shutters cover the storefronts, and the concrete ground is worn and industrial.
