Human Atlas of Tooth Decay Progression: Identification of Cellular Mechanisms Driving the Switch from Dental Pulp Repair Toward Irreversible Pulpitis

Advanced Science, EarlyView.
Tooth decay progression transforms the dental pulp response from repair to fibrosis. At early stages, stromal cells reprogram to repair the extra cellular matrix (ECM), blood vessels, and nerves, remodel and grow, keeping repair possible. In advanced decay, hypoxia, and vessel regression, in complement with an immune switch, fuel nerve degeneration and

High-Level Bottom-Up Cues for Top-Down Parsing of Facade Images [PDF]

, 2012
International audienceWe address the problem of parsing images of building facades. The goal is to segment images, assigning to the resulting regions semantic labels that correspond to the basic architectural elements.

Quantifying the Single‐Cell Morphological Landscape of Cellular Transdifferentiation through Force Field Reconstruction

Advanced Science, EarlyView.
This study reconstructs the driving force field of fibroblast‐to‐neuron transdifferentiation from sparse single‐cell images by decomposing it into flux and time‐dependent potential gradient, extending the landscape‐flux framework to non‐steady‐state systems.

Precedence Table Construction Algorithm for CFGs Regardless of Being OPGs

Algorithms
Operator precedence grammars (OPG) are context-free grammars (CFG) that are characterized by the absence of two adjacent non-terminal symbols in the body of each production (right-hand side).

Biomimetic High‐Order Encoder for Trichromatic Recognition Based on Flexible MoS2 Ring Oscillators

Advanced Electronic Materials, EarlyView.
MoS2‐based ring oscillators are fabricated for color and intensity resolved image recognition, which exploit wavelength‐dependent photoresponsivity (400–700 nm) to implement biomimetic spectral coding. Through MoS2 oscillators, light signals are transduced into frequency‐modulated electrical spikes from 265 Hz to 3.8 kHz, establishing hardware ...

Blackboard Agents for Standard Arabic Language Tokenization and Parsing

Journal of Engineering and Sustainable Development, 2010
The Processing of the Arabic language is a difficult mission comparing it with other languages. Because Sentences in Arabic language are complex, longer than the others in various languages, and have difficult structure with lattices.

Large Language Model in Materials Science: Roles, Challenges, and Strategic Outlook

Advanced Intelligent Discovery, EarlyView.
Large language models (LLMs) are reshaping materials science. Acting as Oracle, Surrogate, Quant, and Arbiter, they now extract knowledge, predict properties, gauge risk, and steer decisions within a traceable loop. Overcoming data heterogeneity, hallucinations, and poor interpretability demands domain‐adapted models, cross‐modal data standards, and ...
