On the Determination and Use of Principal Lines
Engineering Transactions, 1977 Assuming plane strain for Huber-Mises yield condition (for a Coulomb-Tresca one, both plane strain and stress are admitted) of incompressible homogeneous isotropic ideal plastic medium, basic relation of principal lines (of curvatures and their ...

Performance Estimation and Ex Vivo Validation of Untethered Magnetic Robots in Soft Tissue
Advanced Science, EarlyView.This study presents an empirical model that quantitatively predicts the step‐out frequency of screw‐type untethered magnetic robots (UMRs) in soft viscoelastic environments, including ex vivo brain tissue. By integrating key parameters into a dimensionless framework, the model enables estimation of robot performance across a range of biological ...

Angewandte Chemie, EarlyView.Same building blocks, different destinies. Pathway complexity directs nucleic acid–loaded polyion complex micelles along distinct assembly trajectories, resulting in either hexagonally shaped or spheroidal nanoparticles with distinct internal structuring.

Advanced Science, EarlyView.A metasurface‐enabled helical wavefront fingerprint (MHWF) paradigm is proposed for quantitative and specific retrieval of a liquid medium's refractive index and extinction coefficient. The liquid's complex dielectric response governs the wavefront evolution of the metasurface‐generated focused vortex beam, forming a distinctive three‐dimensional ...

Generalized logarithmic spirals for low-thrust trajectory design
, 2016 Shape-based approaches are practical for finding sub-optimal solutions during the preliminary design of low-thrust trajectories. Logarithmic spirals are the simplest, but of little practical interest due to having a constant flight-path angle.

Wafer‐Scale 3D Integration for High‐Density Multi‐Valued Neuromorphic Logic
Advanced Science, EarlyView.Wafer‐scale 3D vertically integrated multi‐valued logic (MVL) circuits are realized by monolithically integrating a Te/IGZO heterojunction FET with an engineered Te pull‐up FET. Heterointerface‐mediated transport and optimized current matching enable stable ternary operation, while vertical stacking reduces circuit footprint and interconnect complexity,

LOGARITHMIC SPIRAL LIGHT PIPE FOR SCINTILLATORS [PDF]
, 1960 A prccedure is described for designing and making logarithmic spiral light pipes which are to be used in coupling scintillators to photomultipliers in cases where the scintillator must be placed in a strong magnetic field. (C.J.G.)

Advanced Science, EarlyView.AARS1 drives PI3K–AKT–mTOR‐dependent glycolysis in bladder cancer, promoting lactate accumulation, increased lactylation, H3K27la enrichment at the HK2 promoter, and HK2 transcription. HK2 reinforces glycolysis, sustaining a metabolic–epigenetic program associated with tumor progression, recurrence, and metastasis.
