A Novel Gradient-Based Method for Decision Trees Optimizing Arbitrary Differential Loss Functions

Mathematics
There are many approaches for training decision trees. This work introduces a novel gradient-based method for constructing decision trees that optimize arbitrary differentiable loss functions, overcoming the limitations of heuristic splitting rules ...

Explainable Intelligent Framework for Reliable Drilling Rate Prediction and Feature Selection in Complex Sedimentary Formations

Journal of Petroleum Geology, EarlyView.
ABSTRACT Accurate prediction of the drilling rate of penetration (ROP) is crucial to optimizing drilling performance, wellbore stability, enhancing operational efficiency, and reducing the overall cost of hydrocarbon exploration. This study focused on evaluating and comparing different machine learning models for ROP prediction and identifying the most

Root hairs and mycorrhiza represent alternative phylogenetically conserved strategies for belowground absorptive surface maximization

New Phytologist, EarlyView.
The phylogenetically conserved trade‐off between the investment in root hairs and mycorrhization formation. Summary Plants take up nutrients from the soil while investing in absorptive root surface or mycorrhizal partners. Root hairs – a major structure for nutrient uptake and cheap to build – increase the absorptive root surface.

Toxic utopia: Unseen ideology and “Le Politique” in China Miéville's The City & The City

Orbis Litterarum, EarlyView.
Abstract What if ideology were not just hidden—but aesthetic? This article reads China Miéville's The City & The City not as a metaphor for division, but as a speculative blueprint for how politics operates through enforced invisibility. By threading Derrida's Absolute Other and Rancière's le politique through Miéville's uncanny urban layering, we ...

Circadian regulation of reproduction and neoblast cell division in the catenulid flatworm Stenostomum virginianum (Platyhelminthes)

Photochemistry and Photobiology, EarlyView.
The circadian clock and melatonin coordinate homeostasis in many animals, yet their influence on reproduction and neoblast proliferation has only been shown in triclads. This study demonstrates that the early‐branching catenulid Stenostomum virginianum contains photoreceptive refractile bodies, synthesizes endogenous melatonin, and that exogenous ...

Long‐term stability of conventional non‐regenerative periodontal treatment for furcation defects

Periodontology 2000, EarlyView.
Abstract Background Furcation involvement (FI) in multi‐rooted teeth poses significant challenges in periodontal therapy due to complex anatomy and difficulty in achieving effective maintenance. FI is associated with increased periodontal destruction, especially in sites with narrow furcation entrances and deep root concavities.

Mulching does not improve seedling survival or growth during early forest restoration

Restoration Ecology, EarlyView.
Abstract Introduction Weed control is one of the main operational challenges and cost components of tropical forest restoration in former pasturelands. Physical barriers (mulches) have been proposed as an alternative to conventional ring weeding because they can suppress competing vegetation while potentially improving the soil microenvironment ...
