Upsampling DINOv2 Features for Unsupervised Vision Tasks and Weakly Supervised Materials Segmentation

Advanced Intelligent Systems, EarlyView.
Feature from recent image foundation models (DINOv2) are useful for vision tasks (segmentation, object localization) with little or no human input. Once upsampled, they can be used for weakly supervised micrograph segmentation, achieving strong results when compared to classical features (blurs, edge detection) across a range of material systems.

Understanding the metabolic perturbations in Carica papaya Linn. due to different ripening practices/agents using gas chromatography‐mass spectrometry based metabolomics

Analytical Science Advances, 2020
The study of fruit‐ripening mechanism is vital as it plays a key role in the maintenance of fruit quality. Use of various xenobiotics for quick ripening has been shown to impact the quality of fruit, which in turn affect human health.

Beyond Acetylene: Exploring Solvent Stabilization of Calcium Carbide‐derived Acetylide Intermediates and Their Significance in Small Organic Molecule Synthesis

ChemistrySelect
The reaction of calcium carbide with water has been widely used as a source of acetylene for the synthesis of organic molecules. In contrast with this traditional approach, we use the CaC2 reaction under water‐starved conditions and show reactions that ...

A Dithio Vinylthio C2 Synthon Enabling Crystalline and Luminescent Sulfur‐Decorated Polymers

Angewandte Chemie International Edition, EarlyView.
Transforming CaC2 into a modular C2 building block enables the synthesis of α,ω‐bis(vinylthio) monomer and its conversion into crystalline, sequence‐defined sulfur‐decorated polymers. Their dense thioether clustering induces nonconventional luminescence and provides structure–function control in a more‐sustainable polymer platform.

Sprouting of Yam Bulbils as Affected by Chemical Treatment

Davao Research Journal, 1999
The sprouting of yam (Dioscorea alata cv. Baligun-on) bulbils treated with ethephon (up to 10,000 ppm) and calcium carbide (up to 100,000 ppm) was neither hastened nor delayed.

In‐vitro puncture experiment using alligator teeth tracks the formation of dental microwear and its association with hardness of the diet

The Anatomical Record, EarlyView.
Abstract With the development of dental microwear texture analysis (DMTA), there has been an increasing application of DMTA for dietary estimation in extant and fossil reptiles, including dinosaurs. While numerous feeding experiments exist for herbivorous mammals, knowledge remains limited for carnivorous reptiles. This study aimed to qualitatively and
