Localized Temperature Monitoring in Mouse Brain during Light Delivery via a Non‐Planar Tapered Fiber‐Integrated µRTD Sensor

Advanced Materials, EarlyView.
We report a multifunctional tapered optical fiber integrating a conformal micro‐resistance temperature detector (µRTD) for local, real‐time thermometry during optical stimulation. The platform combines light‐delivery and temperature sensing within a minimally invasive footprint, enabling detection of sub‐degree cortical heating under representative ...

The Local Multiplier Algebra of a C*-Algebra, II

Journal of Functional Analysis, 2000
[Part I by the author in Q. J. Math., Oxford (2) 47, No. 185, 123-132 (1996; Zbl 0857.43004).] Let \(A\) be a separable \(C^*\)-algebra and let \(M_{\text{loc}}(A)\) be its local multiplier algebra. It is shown that every minimal closed prime ideal of \(M_{\text{loc}}(A)\) is primitive.

Room‐Temperature Skyrmionic Synapse in 2D Ferromagnet Fe3GaTe2 Operating via Collective Spin Texture Transformation

Advanced Materials, EarlyView.
We demonstrate a neuromorphic synapse in 2D Fe3GaTe2 flakes. The device operates via a current‐driven transformation from a skyrmion‐lattice to a stripe‐domain state, yielding a linear anomalous Hall resistance response with a tunable slope to enable multiply‐accumulate operations. Simulations confirm its viability in artificial neural networks.

Dynamical Modeling and Distributed Vibration Control for the Multi-Plate Jointed by Hinges

IEEE Access
The dynamical characteristics and vibration control for the multi-plate jointed by hinges are investigated in this paper. The connection for the multi-plate fixed on the external component is the discontinuous interval constraint, which is different the ...

Filtrations and local syzygies of multiplier ideals II

Journal of Pure and Applied Algebra, 2010
The vanishing orders of local syzygies of multiplier ideals have been studied by \textit{R. Lazarsfeld} and the reviewer [Invent. Math. 167, No. 2, 409--418 (2007; Zbl 1114.13013)] and the author's previous papers including the first part [\textit{S. Lee}, J. Algebra 315, No. 2, 629--639 (2007; Zbl 1135.13006)].

Large‐Area 2D Metasurface‐Based Triboelectric E‐Skin Arrays: Contact & Proximity Tactile Mapping with Broadband Acoustic Readouts

Advanced Materials, EarlyView.
Metasurface‐engineered NC‐TENG arrays integrate tactile pressure mapping, non‐contact gesture sensing, and acoustic signal readouts in one ultrathin module, and outperforms pristine PDMS in terms of electrical output and real‐time spatial mapping for next‐gen wearables.

The local geometry of idempotent Schur multipliers

Forum of Mathematics, Pi
A Schur multiplier is a linear map on matrices which acts on its entries by multiplication with some function, called the symbol. We consider idempotent Schur multipliers, whose symbols are indicator functions of smooth Euclidean domains.

All‐Optical Reconfigurable Physical Unclonable Function for Sustainable Security

Advanced Materials, EarlyView.
An all‐optical reconfigurable physical unclonable function (PUF) is demonstrated using plasmonic coupling–induced sintering of optically trapped gold nanoparticles, where Brownian motion serves as a robust entropy source. The resulting optical PUF exhibits high encoding density, strong resistance to modeling attacks, and practical authentication ...
