Iron(III) ion reinforced P(NiPAAm‐co‐AA) beads as tunable smart organogels

Polymer International, EarlyView.
Macroporous beads of PNiPAAm‐co‐AA copolymers were further crosslinked by iron(III) ions. The resulting beads are mechanically robust and reversibly responsive to a change of solvent from ethanol to ethyl acetate with half‐lives in the range of minutes.

Automatic insect identification, counting, and monitoring techniques: a review

Pest Management Science, EarlyView.
Automated insect monitoring increasingly integrates optical, acoustic, infrared, radar, electrostatic, and biosensing technologies with artificial intelligence. No single approach is universally optimal; reliable deployment depends on task‐specific validation, representative datasets, robustness under field conditions, energy autonomy, connectivity ...

Current-Feedback RST Thrust Regulation Within a Nested Saturation Attitude Loop: Design, Embedded Realisation and Characterisation on 8-Bit Hardware

Actuators
Advanced quadrotor control is validated predominantly in simulation or on 32-bit floating-point flight computers, leaving open whether comparable architectures are deployable on the low-cost 8-bit hardware common to small-scale platforms.

Invisible near‐infrared thermo‐stimulated luminescence from carbon dots enabled by stepwise energy transfer for concealed information encryption

Responsive Materials, EarlyView.
A fully metal‐free near‐infrared (NIR) thermo‐stimulated luminescent system is developed by embedding carbon dots into a carbon nitride matrix and integrating multistage Förster resonance energy transfer. The system exhibits long‐term charge retention, rewritable optical memory, and highly concealed NIR readout, promising for secure data encryption and

Rapid Fabrication of Sub‐100 µm Microstructures In Situ via Femtosecond Laser for Correlative Imaging of Rare Cells

Small, EarlyView.
In this work, a femtosecond (fs) laser processing strategy is demonstrated for rapid and targeted fabrication of 3D sub‐100‐µm microstructures on resin‐embedded cells. The fabricated array of sub‐100‐µm pillars (each loaded with flow‐sorted T‐cell subsets) is arranged in a half‐grid geometry to enable efficient use of the scarce biological sample and ...

A Multi‐Sequence Adversarial Fusion U‐Net for Brain Tumor Image Segmentation

IEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
In the field of brain tumor image segmentation, in order to avoid the impact of insufficient number of training samples, the method of fusing multi‐modal MRI information before segmentation is widely used. However, when fusing different modal features, existing methods only add fixed weights to the features of each modality, resulting in insufficient ...

Field evaluations of thermal optics and tracking tunnels for small mammal surveys at airports and grass dominated habitats

Wildlife Society Bulletin, EarlyView.
Small mammal survey tools are needed at airports to help inform aircraft strike‐risk management. We evaluated thermal optics and tracking tunnels as small mammal survey tools. We conclude that thermal optics would not be a viable survey tool for mouse‐sized mammals (19‐41 g) at airfields and other thick grass habitats unless grass height was maintained

Phloroglucinol inhibits human ureteral contractions via activation of cAMP‐PKA pathway

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Phloroglucinol is used to treat renal colic, especially when non‐steroidal anti‐inflammatory drugs are contraindicated. This study aimed to clarify its mechanism by examining effects on human ureteral contractility and underlying signalling pathways. Experimental Approach Urinary levels of neurokinin A (NKA), substance P

USP25 promotes ferroptosis in diabetic retinopathy by deubiquitinating p53 and suppressing the GPX4/SLC7A11 axis

Journal of Diabetes Investigation, EarlyView.
ABSTRACT Objective To explore the expression of the deubiquitinase (DUB) USP25 in diabetic retinopathy (DR) and its mechanistic role in regulating ferroptosis. Methods Bioinformatics was used to screen for DR‐related DUB candidate genes. USP25 expression was validated in a streptozotocin‐induced diabetic mouse model and high glucose (HG)‐treated ARPE ...
