Ultrasensitive Anti‐Stokes Luminescence Thermometry in Transition Metal Dichalcogenide Monolayers
Advanced Functional Materials, EarlyView.We demonstrate a highly sensitive nanothermometer using anti‐Stokes photoluminescence, also known as photoluminescence upconversion (UPL), in monolayer tungsten disulfide. A strong resonantly enhanced UPL is observed, confirming the central role of optical phonons in the PL upconversion mechanism.

Quaternion-Based Acoustic SLAM for 3D Drone Localization and Source Mapping
IEEE Open Journal of Signal ProcessingAccurate localization and mapping are challenging in environments with poor visibility or noise interference, such as underwater, at night, or in fog, where visual data are unreliable or limited.

Shaping Matter with Acoustic Waves: From Particles to Functional Structures
Advanced Functional Materials, EarlyView.Acoustic‐directed assembly is reviewed as a materials‐oriented strategy for organizing particles, polymers, metals, and biological systems into functional structures. The review distinguishes reversible manipulation from permanent structure formation through medium fixation, particle fixation, and in situ material generation, highlighting routes toward

EchoSLAM: Simultaneous localization and mapping with acoustic echoes
2016 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2016 We address the problem of jointly localizing a robot in an unknown room and estimating the room geometry from echoes. Unlike earlier work using echoes, we assume a completely autonomous setup with (near) collocated microphone and the acoustic source.

Relying on critical articulators to estimate vocal tract spectra in an articulatory-acoustic database [PDF]
, 2010 We present a new phone-dependent feature weighting scheme that can be used to map articulatory configurations (e.g. EMA) onto vocal tract spectra (e.g. MFCC) through table lookup.

Robust 3D-Mapping with Time-of-Flight Cameras
, 2009 Time-of-Flight cameras constitute a smart and fast technology for 3D perception but lack in measurement precision and robustness. We present a comprehensive approach for 3D environment mapping based on this technology.

Optimization of passive acoustic bedload monitoring in rivers by signal inversion [PDF]
Earth Surface DynamicsRecent studies have shown that hydrophone sensors can monitor bedload flux in rivers by measuring the self-generated noise (SGN) emitted by bedload particles when they impact the riverbed. However, experimental and theoretical studies have shown that the

Natural Biomaterials for Osteochondral Repair: From Source to Strategy
Advanced Healthcare Materials, EarlyView.Biological origin‐guided overview of natural biomaterials and therapeutic strategies for osteochondral tissue engineering. The circular diagram categorizes representative materials and strategies into plant/algae‐derived, microbial‐derived, animal‐derived, and human‐derived sources, centered on an osteochondral defect repair model.
