Global solutions for 3D nonlocal Gross-Pitaevskii equations with rough data

open access: yesElectronic Journal of Differential Equations, 2012
We study the Cauchy problem for the Gross-Pitaevskii equation with a nonlocal interaction potential of Hartree type in three space dimensions. If the potential is even and positive definite or a positive function and its Fourier transform decays ...

The Seasonal Rhythms of Coastal eDNA: Insights Into Biodiversity and Regional Detection Patterns

open access: yesEnvironmental DNA, Volume 8, Issue 1, January–February 2026.
Seasonal variation affects environmental DNA (eDNA) detection, yet its influence on species monitoring remains underexplored. This study examines eDNA detection windows across taxa, primers, and regions, finding that most species have short detection periods (1–2 months) that vary with taxonomy and primer choice. These results underscore the importance

Low regularity solutions for Chern-Simons-Dirac systems in the temporal and Coulomb gauge

open access: yesElectronic Journal of Differential Equations, 2016
We prove low regularity local well-posedness results in Bourgain-Klainerman-Machedon spaces for the Chern-Simons-Dirac system in the temporal gauge and the Coulomb gauge.

Metal Phthalocyanine Sensitized Photoelectrochemical Cell Assembling with Azide‐Functionalized Reduced Graphene and Quaternary Metal Chalcogenide Composites

open access: yesChemElectroChem
Here, photoelectrodes of photoelectrochemical (PEC) cells consisting of azide functionalized reduced graphene oxide (GO‐N3) and quaternary metal chalcogenide (CdZnNiSSe) composites sensitized with metal phthalocyanines (MPc, M: Co, Zn, Ti) are developed ...

A semi‐analytical Bayesian estimate retrieval algorithm for the inversion of remote‐sensing reflectance in optically deep and shallow waters

open access: yesLimnology and Oceanography: Methods, Volume 24, Issue 1, January 2026.
Abstract The inverse problem in remote sensing of aquatic environment consists in retrieving optically significant constituents (OSCs) from a spectral measurement of the remote sensing reflectance (Rrs).Optically significant constituent includes chlorophyll a concentration (Chl a), a proxy of phytoplankton biomass, absorption of colored detrital matter

Dispersion-mediated steering of organic adsorbates on a precovered silicon surface

open access: yesBeilstein Journal of Organic Chemistry, 2018
The chemistry of organic adsorbates on surfaces is often discussed in terms of Pauli repulsion as limiting factor regarding the packing of molecules. Here we show that the attractive part of the van der Waals potential can be similarly decisive.

Stratigraphy of Carbonate‐Bearing Rocks at the Margin of Jezero Crater, Mars: Evidence for Shoreline Processes?

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract Martian carbonate‐bearing rocks are compelling targets for exploration because they preserve detailed records of past aqueous processes, climate, and habitability. The Margin unit in Jezero crater is a distinct olivine‐ and carbonate‐bearing unit stratigraphically underlying the western fan, lining the inner margin of the western crater rim ...

An integrated integral projection model (IPM2) to disentangle size‐structured harvest and natural mortality

open access: yesJournal of Animal Ecology, Volume 95, Issue 1, Page 157-174, January 2026.
An IPM2—a combination of an integrated population model and integral projection model—creates a synergistic modelling framework useful for disentangling multiple size‐structured demographic rates and understanding the effectiveness of invasive European green crab removal efforts.

Global solutions with infinite energy for the one-dimensional Zakharov system

open access: yesElectronic Journal of Differential Equations, 2005
The one-dimensional Zakharov system is shown to have a unique global solution for data without finite energy. The proof uses the ``I-method'' introduced by Colliander, Keel, Staffilani, Takaoka, and Tao in connection with a refined bilinear Strichartz ...

Modality switching in a property verification task: an ERP study of what happens when candles flicker after high heels click

open access: yesFrontiers in Psychology, 2011
The perceptual modalities associated with property words, such as flicker or click, have previously been demonstrated to affect subsequent property verification judgments (Pecher et al., 2003). Known as the conceptual modality switch effect, this finding
