Parallel Vectors Extraction using Bézier Clipping
Abstract In this paper, we propose a novel local feature extraction algorithm for the parallel vectors (PV) operator. Our method is based on Bézier clipping, which is a bracketing‐based root finding method that is commonly‐used in computer‐aided geometric design.

Single Line Drawing Generation via Semantics‐Driven Optimization
We present a method for automatically generating single‐line drawings in vector format, guided by a text prompt or an input image. Our approach leverages score distillation sampling to optimize the parameters of a uniform rational B‐spline (URBS) curve, ensuring that the drawing consists of a single continuous stroke by design.

Parasitoid wasps deploy maternal and embryonic factors to reprogramme host physiology. Venom, calyx fluid, polydnaviruses, teratocytes and larval secretions act in a coordinated, compartmentalised manner. Host‐regulation factors are promising sources of insecticidal, antimicrobial and bioinspired translational molecules.

Parameter‐Preserving Real‐time BIM Rendering via Direct GPU Ray Tracing
Parametric BIM geometry is preserved from Revit extraction to GPU ray tracing without mesh tessellation. A two‐tier cache reuses repeated geometry during export, and an instanced OptiX representation reduces memory at render time. The method lowers export time and GPU memory while preserving exact curved surfaces.

MGGAN learns complex, high‐dimensional patterns and geometric statistics of a single 3D mesh using a multiscale graph‐based generative adversarial network. By combining spectral and spatial graph operators in a coarse‐to‐fine framework with noise injection at each scale, the method generates smooth, visually coherent, and topology‐preserving shape ...

Ultra‐Compact Low‐Loss 3D Glass Waveguide Chip Using Femtosecond Laser Writing Technique
An ultra‐compact, low‐loss fan‐in/fan‐out device for 4‐core fiber is demonstrated using femtosecond laser direct writing. Multi‐scan and overwriting methods are employed to produce low‐loss waveguides. A trench‐assisted offset‐assisted cosine‐shaped model is proposed to reduce bending loss.

ABSTRACT This work addresses the challenge of bidirectional trajectory tracking in solar‐powered wheeled mobile robots (WMRs), considering the mechanical structure, actuator‐driver, and power stage subsystems. Notably, this is the first study to explicitly model and control the actuator‐driver subsystem within this context. The proposed solution relies

Martian Proton Albedo as Signature of Near‐Surface Water
Abstract Understanding the Martian soil water budget is crucial not only for in situ resource utilization in future human missions to Mars, but also for reconstructing the geological and climatic history of the planet, as well as to assess the potential of ancient or even present microbial life.

In Situ Characterisation of Hydrogels via Dynamic Interface Printing
ABSTRACT Hydrogels have become pivotal materials for tissue engineering, robotics, biomedical devices, and sensing applications due to their diverse material compositions and tunable mechanical properties. While significant effort has focused on developing novel manufacturing approaches such as extrusion bioprinting and light‐based fabrication methods,
