Nanothermometry in Living Cells: Physical Limits, Conceptual and Material Challenges
Advanced Functional Materials, EarlyView.Heat and temperature are fundamental to life. When nanothermometers began probing regions as small as a living cell, they triggered controversial claims of large intracellular temperature gradients. We review physical constraints energy‐conservation, entropy production, thermodynamic fluctuations, and molecular dynamics.

Stationary infinitely divisible processes
Brazilian Journal of Probability and Statistics, 2011 This paper reviews various types of continuous time stationary and infinitely divisible processes and adds some new results. In Section 2 the author gives background results on inifinite divisibility and Levy bases. Extended subordination and meta-times are considered in Section 3. Ambit fields and processes are briefly discussed iun Section 4.

4D‐Printed Magneto‐Plasmonic Microrobots for Programmable Spatiotemporal De‐Icing
Advanced Functional Materials, EarlyView.A 4D‐printing strategy is introduced to achieve programmable de‐icing devices. By aligning gold–magnetite nanofillers within a photosensitive resin, the printed structures exhibit dual magnetic and plasmonic functionalities, enabling precise spatio‐temporal ice removal through thermoplasmonic effects.

On Truncation of the Matrix-Geometric Stationary Distributions
Mathematics, 2019 In this paper, we study queueing systems with an infinite and finite number of waiting places that can be modeled by a Quasi-Birth-and-Death process. We derive the conditions under which the stationary distribution for a loss system is a truncation of ...

Adaptive Hydrogels With Spatiotemporal Stiffening Using pH‐Modulating Enzymes
Advanced Functional Materials, EarlyView.The chemomechanical coupling in an adaptive hydrogel is studied to further the development of adaptive hydrogels. This coupling is achieved by embedding a pH‐modulating enzyme in a pH‐responsive hydrogel. The enzymatic reaction can be triggered locally, which generates a pH‐decreasing wave throughout the system, increasing the crosslinking density and ...
