Estimation of the carbon sink of rock weathering by remote sensing and analysis of its spatiotemporal variations

Carsologica Sinica
As a type of natural carbon sink, rock weathering plays a critical role in the global carbon cycle by storing atmospheric carbon dioxide (CO2). This process is particularly significant in mitigating climate change, although its contributions are often ...

Thermally Drawn Bioelectric Catheters: Enabling Proprioceptive Endovascular Navigation

Advanced Intelligent Systems, EarlyView.
This work introduces a novel bioelectric navigation system eliminates the need for harmful fluoroscopy during endovascular surgeries. A bespoke 16‐electrode catheter is fabricated using rapid thermal drawing and laser micro‐machining. Paired with a real‐time tracking algorithm fusing vascular geometry detection and distance estimation, this technology ...

Dynamic time warping (DTW).

, 2018
DTW aims to find a non-linear agreement between two-time series. Let’s consider two time series Q and C with the same number of time points n where Q = q1, q2…, qn and C = c1, c2 …, cn, it can build the M matrix of dimension n×n matrix whose i, jth ...

The internal crest anatomy of Lambeosaurini (Hadrosauridae: Lambeosaurinae)

The Anatomical Record, EarlyView.
Abstract The supracranial crests of lambeosaurine hadrosaurids have long been a focus of study due primarily to their extreme morphology. The external anatomy of lambeosaurine crests is understood to be highly variable between species, but variation in their internal anatomy is less well understood.

On Discrete Time Wilson Systems

Journal of Mathematics, 2020
In this paper, we define the discrete time Wilson frame (DTW frame) for l2ℤ and discuss some properties of discrete time Wilson frames. Also, we give an interplay between DTW frames and discrete time Gabor frames.

Let's do the time warp again: non‐linear time series matching as a tool for sequentially structured data in ecology

Ecosphere, 2021
Ecological patterns are often fundamentally chronological. However, generalization of data is necessarily accompanied by a loss of detail or resolution. Temporal data in particular contain information not only in data values but in the temporal structure,

Automatic Generation of Piano Score Following Videos

Transactions of the International Society for Music Information Retrieval, 2021
This article studies the problem of generating a piano score following video from an audio recording in a fully automated manner. This problem contains two components: identifying the piece and aligning the audio with raw sheet music images.
