An improved view of cosmic-ray transport and the galactic outflow in NGC 253

The nearly edge-on starburst galaxy NGC 253 has been observed to exhibit extended halo emission in multiple bands, making it an ideal laboratory for studying the transfer of matter from the disk to the halo. We aim to determine how the cosmic-ray electrons (CREs) flow from the disk to the halo and understand what drive...

Self-organized vegetation patterns promote persistence of plant–pollinator mutualisms under environmental stress

Mutualisms are key for structuring ecological communities, but they are sensitive to environmental change and fluctuations in population size. Consequently, how mutualisms achieve stability remains an open question in ecological theory. Motivated by previous results in competitive and predator–prey interactions, and by...

Traveling waves and their spectral instability in a reaction-diffusion-chemotaxis model with volume-filling effect

Multiplexed Nanosensors for Real-Time Monitoring of VOC-Mediated Signalling Response in Plants.

This study captures in real time, the VOC-induced rapid signalling in receiver plants and its ensuing effect on growth, an important advance in deciphering how emitter-specific volatile cues are integrated into plant responses, guiding rational selection of beneficial companion plants for improved yield and nutritional...

SIGNAL-Nano: a sequentially gated red light-activable silicon-rhodamine nanoplatform for mitochondria-targeted theranostics.

A sequentially gated theranostic nanoplatform based on a silicon-rhodamine (Si-Rhod) photocage that integrates endogenous reactive oxygen species sensitivity with externally applied red light activation to achieve spatiotemporally programmable chemotherapy is reported.

Overlimiting Ion Transport and Reaction Limitations in Charged Porous Media

Electrochemical reaction rates are controlled by both interfacial charge-transfer kinetics and reactive-ion transport. In charged porous media, fixed charges enrich reactive counterions near pore walls, enabling transport beyond the classical diffusion limit via surface conduction (SC). Under overlimiting conditions, c...

Coarse-Graining Agent-Based Models of Bacterial Infections

A deterministic coarse-grained description is derived for a class of bacterial-infection ABMs in which immune cells and extracellular bacteria diffuse, immune cells ingest nearby bacteria, and intracellular bacterial loads evolve through prescribed birth and clearance processes that preserves the rule-based structure o...

Mudragen: Geometrically Supervised Generation of Interacting Two-Hand Mudras for Preserving Indian Classical Dance Heritage

Experimental results show that MudraGen surpasses existing state-of-the-art generative approaches in visual realism, anatomical correctness, and preservation of fine hand-pose structure, enabling faithful reproduction of complex Samyukta Hasta mudras.

Numerical analysis of a nonlinear temperature enhanced diffusion model for drug delivery

Evidence accumulation during self-referential social processing captures social functioning and psychopathology dimensions in a transdiagnostic sample

Abstract Background Psychosis, social anxiety, and autism are clinical constructs that share important phenotypic features, particularly social dysfunction. A critical determinant of social functioning is an individual’s ability to recognize when social cues, such as eye gaze, are meant for them. Emerging computational...

Stabilizing Camera-Controlled Novel View Synthesis at Inference Time

CamTrol++ improves temporal and geometric consistency, downstream 3D reconstruction quality, and generation efficiency over training-free baselines over RealEstate10K and MegaScene, and improves temporal and geometric consistency over training-free baselines.

Strongly anisotropic non-Kramers electron spin as a quantum coherence probe of angular fluctuations

Strongly anisotropic non-Kramers rare-earth ions combine giant longitudinal g-factors with a vanishing transverse component imposed by time-reversal symmetry, a combination that makes their spin transitions exquisitely sensitive to the orientation of the applied magnetic field. We show that this sensitivity carries a d...
