Resummation of Cactus Diagrams in Lattice QCD

, 1998
We show how to perform a resummation, to all orders in perturbation theory, of a certain class of gauge invariant diagrams in Lattice QCD. These diagrams are often largely responsible for lattice artifacts.

A Self‐Supervised Machine Learning Approach for the Estimation of Open‐Circuit Voltage Degradation in Photovoltaic Systems

Progress in Photovoltaics: Research and Applications, EarlyView.
This study introduces a self‐supervised machine learning approach integrating physics‐based principles to estimate open‐circuit voltage (voc$$ {v}_{oc} $$) degradation in photovoltaic systems using SCADA data. By combining clustering and regression algorithms, our method detects performance deviations without labelled datasets.

Spectrum of Itinerant Fractional Excitations in Quantum Spin Ice

, 2018
We study the quantum dynamics of fractional excitations in quantum spin ice. We focus on the density of states in the two-monopole sector, rho(omega), as this can be connected to the wave-vector-integrated dynamical structure factor accessible in neutron

Animating blossom: Time‐lapse to encourage plant awareness in the YouTube era

PLANTS, PEOPLE, PLANET, EarlyView.
Time‐lapse videos can effectively capture key traits of flower blossoms, such as color, 3D structure, and temporal changes, making them valuable complements to herbarium specimens and other botanical collections. Despite the abundance of such videos on YouTube, most provide no ecological and botanical insights.

The shared benefits of fallen fruits: A novel mechanism stabilizing a nursery pollination mutualism between Sambucus and kateretid beetles

PLANTS, PEOPLE, PLANET, EarlyView.
Understanding how cooperative interactions remain stable matters for biodiversity because many plants rely on specialist insects that can also impose reproductive costs. We studied the interaction between Sambucus sieboldiana and seed‐consuming Heterhelus beetles through detailed field observations and pollination experiments.

Geomorphic Responses to Post‐Grazing Recovery and Stream Restoration in Semiarid Grassland Streams

River Research and Applications, EarlyView.
ABSTRACT Semiarid grassland streams are sensitive to land use, climate, extreme discharges, and internal geomorphic thresholds that drive episodic erosion. Rooted in a process‐based philosophy and commonly applied to historically wood‐rich, beaver‐modified systems, low‐tech process‐based restoration using structures is increasingly being extended to ...

Retrospective image analysis for long‐term demography using Google Earth imagery

Remote Sensing in Ecology and Conservation, EarlyView.
We demonstrate that high‐resolution Google Earth imagery, combined with minimal field validation, enables retrospective tracking of individual invasive plants. The image shows one of the monitored individuals of Opuntia sp. in Greece. Our approach reveals long‐term demographic patterns, recruitment dynamics, and spatial expansion without continuous ...

MXene 3D‐AJP: Three‐Dimensional Well‐Oriented Freeform Networks of 2D MXene Nanosheets via Aerosol‐Based 3D Printing

Small, EarlyView.
This study presents an additive‐free aerosol jet 3D printing technique for assembling 2D MXene nanosheets into complex, customizable, high‐aspect‐ratio 3D microarchitectures without binders. By leveraging real‐time ink thickening, the authors also fabricate 3D microsupercapacitors with interdigitated electrodes that holds breakthrough device areal ...
