Research progress on the use of the optical coherence tomography system for the diagnosis and treatment of central nervous system tumors

open access: yesIbrain, Volume 11, Issue 1, Page 3-18, Spring 2025.
With the advantages of high‐resolution imaging, efficient image acquisition, intraoperative real‐time detection, and radiation‐free and noninvasive characteristics, optical coherence tomography (OCT) provides accurate diagnosis and effective intraoperative guidance for the minimally invasive diagnosis and treatment of central nervous system (CNS ...

Defects‐Triggered In Situ Reconstruction in Metal‐Halide Perovskites for Photo‐Rechargeable Lithium‐Ion Batteries

open access: yesInterdisciplinary Materials, EarlyView.
This work presents a strategy for the in situ formation of heterostructures in bifunctional photoelectrodes for photo‐rechargeable lithium‐ion batteries (PRLIBs). Defect‐driven reconstruction in metal‐halide perovskites (MHP) activates Cu+/Cu2+ leaching from the current collector, thereby enabling the in situ formation of CuO/CuI‐MHP heterojunctions ...

Orientations of Graphs With at Most One Directed Path Between Every Pair of Vertices

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT Given a graph G $G$, we say that an orientation D $D$ of G $G$ is a KT orientation if, for all u , v ∈ V ( D ) $u,v\in V(D)$, there is at most one directed path (in any direction) between u $u$ and v $v$. Graphs that admit such orientations have been used to construct graphs with large chromatic number and small clique number that served as ...

Non‐Uniform Programmable Photonic Waveguide Meshes

open access: yesLaser &Photonics Reviews, EarlyView.
Integrating defect cells into uniform hexagonal waveguide meshes overcomes the fundamental spectral and temporal limitations of programmable photonics. By leveraging the Vernier effect through non‐uniform coupled cavities, this architecture achieves a tenfold increase in free spectral range and ultra‐fast sampling times, paving the way for next ...

Rapid Discovery of TiO2/ZnFe2O4/Cu Ternary Photocatalysts for Volatile Organic Compounds Degradation via High‐Throughput Screening Photogenerated Carriers Transfer Properties

open access: yesMaterials Genome Engineering Advances, EarlyView.
This study develops a high‐throughput screening method using carrier mobility as a key descriptor. Taking the TiO2/ZnFe2O4/Cu ternary photocatalytic system as an example, we rapidly identify high‐performance components for VOCs degradation, confirm that the performance trends of thin‐film catalysts match those of their powder counterparts with the same

3D effects of seawater on electrical resistivity tomography near shorelines—Challenges and possible solutions inferred from synthetic and field data

open access: yesNear Surface Geophysics, EarlyView.
Abstract Electrical resistivity tomography (ERT) is one of the most widely used geophysical techniques for hydrogeological questions, such as investigating the groundwater transition zone between land and sea. The interpretation of 2D coast‐parallel ERT profiles is challenging because most of the electrical current flows through the highly conductive ...

Spatiotemporal Assessment of Groundwater Interactions With a Regulated River: A Case Study of the Nechako River, Canada

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Regulated rivers represent complex hydrological systems where groundwater–surface water interactions are governed by natural conditions and human interventions. This study investigates the spatiotemporal dynamics of groundwater–surface water exchanges in the Nechako River, British Columbia (Canada), using numerical simulations.

On the compatibility of single‐scan terrestrial LiDAR with digital photogrammetry and field inventory metrics of vegetation structure in forest and agroforestry landscapes

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
The single‐scan approach to terrestrial laser scanning (TLS) and the self‐terrain‐normalized form of drone‐based digital aerial photogrammetry (DAP) offer practical options for rapid assessment of the vegetation structure in tropical landscapes.

Low Temperature Site‐Specific Pulsed Laser Annealing of MoS2

open access: yesSmall, EarlyView.
The application of laser pulses, of extremely short duration, is investigated as a potential new method to modify the atomic structure of ultrathin 2D materials for use in the creation of future electrical devices. The process is efficient, offering a site‐specific functionality, where regions of an electronic device that only requires annealing is ...
