Revealing Chronotypes Across Aquatic Species Using Acoustic Telemetry
Fish and Fisheries, Volume 26, Issue 6, Page 1134-1145, November 2025.ABSTRACT Acoustic telemetry offers valuable opportunities to investigate individual variability in circadian‐related and other behaviours and how environmental cues shape these patterns in wild fish populations. However, this potential has not yet been fully exploited.

Blind estimation of spreading sequence of CDMA signals based on Fast-ICA and performance analysis
Tongxin xuebao, 2011 The DS-CDMA signals can be divided into two types,the short-code（SC） and the long-code（LC） DS-CDMA signal.The existing methods are only used to estimate spreading sequences of SC-DS-CDMA signals,which cannot work for the LC-DS-CDMA signals.A new blind ...

Advanced Energy Materials, Volume 15, Issue 33, September 2, 2025.Photocatalytic N₂ reduction is a sustainable method for ammonia production. Au nanostars (AuNST) with TiO2 excel, especially when encased in mesoporous silica, enhancing stability and selectivity without scavengers. Electromagnetic fields at nanostar spikes drive hot‐electron transfer to TiO2 for N2 reduction under visible light, while hot holes ...

Self‐Assembly Pathway Influence on Dehydropeptide‐Based Gel Properties and Drug Release
Macromolecular Bioscience, Volume 25, Issue 9, September 2025.In this work, it is explored how the gelation conditions affect the morphology, mechanical properties, and drug release of dehydropeptide‐based gels. The naphthalene‐capped dehydropeptide forms a crystal structure with a pore diameter of ≈4.08 Å. Gelation conditions can influence gel stiffness by nearly three orders of magnitude, in which the assembly ...

Transmission of non-linear binary input functions over a CDMA System
, 2012 We study the problem of transmission of binary input non-linear functions over a network of mobiles based on CDMA. Motivation for this study comes from the application of using cheap measurement devices installed on personal cell-phones to monitor ...

Surface Energy and Morphology of Blend Films of Polystyrene and Polybutadiene
Macromolecular Chemistry and Physics, Volume 226, Issue 17, September 5, 2025.Blends of polystyrene and polybutadiene are highly immiscible and, when cast as films, give rise to many different structures. In this work, different experimental techniques realize the complexity of these films. Given the industrial importance of polystyrene and polybutadiene, understanding morphology is important.
