Ice‐Droplet and Damaged Elastomer Interfaces: A Closer Look at Contact and Morphology of Anti‐Icing Coatings Using Cryo‐FIB‐SEM

Journal of Applied Polymer Science, EarlyView.
Cryo‐FIB‐SEM is used to mill and image the interfaces of ice droplets frozen on PDMS coatings damaged by abrasion and cutting. Both high‐ and low‐real contact areas are revealed for the first time, with interpenetration dependent on the shape of asperities on the damaged surface.

Ultrafast RF Spectrum Analyzer Assisted by Optical Short‐Time Fourier Transform

Advanced Physics Research, EarlyView.
We present Recent efforts in an ultrafast RF spectrum analyzer based on the short‐time Fourier transform (STFT) at over 10 MHz frame rate and over 40GHz bandwidth to improve performance and support applications. All these efforts could inspire more innovative applications of temporal imaging modalities in the future.

Tracing the evolutionary history of the morpho‐anatomy of baculum in primates

The Anatomical Record, EarlyView.
Abstract Animal morphology reflects both evolutionary history and present‐day adaptation. Male mammal copulatory structures such as the baculum (penile bone) are ideal for studying these processes because of their complexity and high interspecific variability. In primates, however, research has focused mostly on baculum length.

Unintegrated Gluon Distributions as Probability Densities for QCD Dynamical Entropy

Astronomische Nachrichten, EarlyView.
ABSTRACT We present a systematic procedure for constructing normalized transverse momentum probability distributions from phenomenological unintegrated gluon distributions (UGDs). These distributions provide the probabilistic foundation of the QCD dynamical entropy formalism and can be employed in the evaluation of other statistical observables.
