Shear‐Mode Direct Piezoelectric Response of Ferroelectric Nematic Liquid Crystals

open access: yesAdvanced Science, EarlyView.
Periodic shear‐induced electric current measurements are reported on two archetypic ferroelectric nematic liquid crystal compounds. From the temperature, frequency and shear angle dependent results of the first and second harmonic current signals together with temperature and oscillatory rheology measurements, the effective piezoelectric coupling ...

Cost of Living Indexes and Exact Index Numbers [PDF]

open access: yes
The paper reviews and extends the theory of exact and superlative index numbers. Exact index numbers are empirical index number formula that are equal to an underlying theoretical index, provided that the consumer has preferences that can be represented ...

Beyond‐Classical Ferroelectric Metamaterials: 3D‐Printed Planar Lattices With Programmable Electro–Thermo–Mechanical Coupling

open access: yesAdvanced Science, EarlyView.
Planar ferroelectric lattices with rationally‐tailored topology and polarization achieve programmable piezoelectric and pyroelectric properties. Analytical modeling, homogenization, and experiments collectively demonstrate enhanced and tunable longitudinal, transverse, and shear piezoelectric responses, together with substantially improved ...

An Expertise Transfer Framework For Autonomous Surgical Assistance

open access: yesAdvanced Science, EarlyView.
This study introduces an expertise transfer framework for procedure‐spanning autonomous surgical assistance. By emulating expert logic through hierarchical perception, attention modeling, and knowledge graph‐based decision‐making, the system provides near‐expert surgical view assistance.

Q‐LEAP: Millisecond Hyperdimensional Optimization for Full‐Spectrum Optical Metamaterials

open access: yesAdvanced Science, EarlyView.
Q‐LEAP integrates physics‐informed residual machine learning with factorization‐machine‐encoded quantum annealing to design full‐spectrum optical metamaterials. It explores a 2108 design space and, in a single 2.56 ms annealing step, reaches 85.83% of the theoretical FoM limit, enabling selective 5‐8 µm emission with 3–5 and 8–14 µm suppression and ∼40×

3D Bioprinted Blood–Brain–Tumor Barrier Spheroid‐Based In Situ Evaluation of Anticancer Compounds Against Glioblastoma: ROS‐Producing Ruthenium as a Potential Therapeutic Candidate

open access: yesAdvanced Science, EarlyView.
The blood–brain–tumor barrier (BBTB) penetration by anticancer drugs and their effects on glioblastoma (GBM) is assessed using 3D bioprinted‐spheroids. Anticancer drug‐induced U‐87 MG cell death is quantified through in situ imaging of spheroids using a cancer cell death probe. The Ru compound, a partial P‐gp substrate, induces greater tumor‐cell death
