The effects of mindfulness‐based interventions on emotion regulation/dysregulation in people with mental health conditions: A systematic review and meta‐analysis

open access: yesJCPP Advances, EarlyView.
Abstract Background We conducted a systematic review and meta‐analysis to examine the effects of mindfulness‐based interventions (MBIs) on emotion regulation (ER) and emotion dysregulation (ED) in people with any mental health condition. Methods Following a pre‐registered protocol (PROSPERO CRD42024618605), we searched multiple databases (Web of ...

Reusable SERS Substrate Based on AuNP/PS‐b‐P2VP Nanocomposites With Photocatalytic Activity

open access: yesJournal of Raman Spectroscopy, EarlyView.
We developed a bifunctional SERS substrate by assembling AuNPs on PS‐b‐P2VP thin films, capable of both sensitive molecular detection and UV‐assisted self‐cleaning. The platform demonstrates excellent reusability over four adsorption–degradation cycles, driven by a hot‐hole‐mediated photocatalytic mechanism without semiconductors.

Exploring portable NIR spectroscopy in transmittance and reflectance modes for the authentication of Brazilian coffees with geographical indications

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Geographical indications (GIs) certify the link between coffee origin and quality, enabling premium pricing and protecting producers. However, the high market value of GI coffees increases their vulnerability to fraud, underscoring the need for reliable and practical authentication methods.

Optically Bound Rapid Plasmonic Nanorod Dimers: Anisotropic Dynamics Driven by Light‐Fluidic Cooperation

open access: yesLaser &Photonics Reviews, EarlyView.
Optically confined gold nanorods exhibit cooperative light‐driven dynamics, forming mobile end‐to‐end dimers with orientation‐dependent propulsion. Using structured laser traps and an opto‐thermo‐hydrodynamic model, we uncover how optical binding, polarization‐induced torque, and near‐surface hydrodynamics govern their motion.

High-frequency asymptotic compression of dense BEM matrices for general geometries without ray tracing

open access: yes, 2018
Wave propagation and scattering problems in acoustics are often solved with boundary element methods. They lead to a discretization matrix that is typically dense and large: its size and condition number grow with increasing frequency.

Urbanization and food transition in the Brazilian Amazon: From wild to domesticated meat

open access: yesPeople and Nature, EarlyView.
Abstract Urbanization is expected to influence food transitions, resulting in a shift from wild foods to more domesticated foods. Concomitantly, food insecurity and urban demand for natural resources, including wildlife, are expected to increase overall, even when the per capita consumption is expected to decrease.

A SVD accelerated kernel-independent fast multipole method and its application to BEM

open access: yes, 2013
The kernel-independent fast multipole method (KIFMM) proposed in [1] is of almost linear complexity. In the original KIFMM the time-consuming M2L translations are accelerated by FFT.

Joint social‐ecological outcomes of private land conservation: An evidence synthesis with a well‐being perspective

open access: yesPeople and Nature, EarlyView.
Abstract Private land conservation (PLC) can contribute to sustainability by improving biodiversity and human well‐being but can also result in negative outcomes for people and nature if poorly designed. Informing PLC design to achieve objectives for joint biodiversity and well‐being is challenging because most evaluations assess ecological and social ...
