Propensity of Predator Mimicry in Steller’s Jays

Birds
Avian vocal mimicry has been described in a variety of contexts, suggesting its function is multifaceted within and across species; however, basic empirical data describing mimetic signal prevalence and context are lacking for numerous species.

Evaluación de aditivos usados en el tratamiento de arcillas expansivas

Ciencia e Ingeniería Neogranadina, 2006
Se utilizaron tres aditivos (cal, cenizas volantes y aceite sulfonado) para disminuir las propiedades de una arcilla altamente expansiva (bentonita), con el fin de determinar las ventajas técnicas de cada alternativa bajo las mismas condiciones y ensayo.

Isocyanate‐Modified Melatplatin(IV) Enhances Antitumor Efficacy via TCF4/COL6A3‐Mediated Extracellular Matrix Remodeling and cGAS‐STING Pathway Activation in Bladder Cancer

Advanced Science, EarlyView.
A series of melatonin‐conjugated platinum(IV) prodrugs was functionalized with isocyanate chains (compounds 5‒12). MP‐12C (compound 11) was identified as the lead candidate, with optimal potency and safety. MP‐12C exhibited greater efficacy than cisplatin by increasing intracellular uptake, reshaping the extracellular matrix, activating the cGAS‐STING ...

Platycodon grandiflorus–Derived Nanovesicles Sensitize Gastric Cancer to T Cell Killing via Ferroptosis‐Driven Membrane Mechanical Remodeling

Advanced Science, EarlyView.
Plant‐derived nanovesicles from Platycodon grandiflorus act as bioactive lipid delivery platforms that transport γ‐linolenic acid into gastric cancer cells. This lipid cargo promotes ferroptotic lipid peroxidation, remodels membrane mechanics, and increases tumor‐cell susceptibility to cytotoxic T‐cell attack.

Developing Metal–Polyphenol Network‐Based Single‐Protein Particle Encapsulation System for Sustained Release of Whey Protein to Mitigate Sarcopenia

Advanced Science, EarlyView.
Sarcopenia has emerged as a major health challenge in the aging population. Developing a sustained‐release system for whey protein may enhance its effectiveness in mitigating sarcopenia. Herein, a novel “single‐protein particle encapsulation” (SPPE) system is developed to protect whey protein and control its release.

Nonlinear Dynamics and Invariants of Motion in ReRAM Cells

Advanced Electronic Materials, EarlyView.
A second‐order cell, hosting one capacitor and two back‐to‐back ReRAMs, admits Invariants of Motion: its states lie on one‐dimensional manifolds at all times. The cell shows quiescent monostability or bistability, depending on the manifold index. At equilibrium, the capacitor voltage vanishes.

From Top to Bottom: Manufacturing Process‐Context Aware Resolution of Energy Device Electrodes Through a 3D Diffusion Generative Model

Advanced Energy Materials, EarlyView.
The application of a generative diffusion model, enhanced with a training data augmentation pipeline retaining the manufacturing process context of electrode microstructures, leads to improved fidelity of the through‐plane tortuosity factor in the AI generated samples.

Tunable Raman Scattering of Fe(II) Coordination Networks With Magnetic Fields

Angewandte Chemie, EarlyView.
Four heavy Hg(II) coordination networks with paramagnetic Fe(II) sites reveal strong and halogen‐tunable low‐frequency (LF) sub‐terahertz phonons and field‐dependent magnetic transitions. LF phonon spectroscopy and Raman magnetospectroscopy are powerful probes of structure, low‐energy vibration, zero‐field splitting, and spin–phonon coupling supported ...
