MaPa: Text-driven Photorealistic Material Painting for 3D Shapes

The aim of this paper is to create materials for 3D meshes based on text descriptions. In contrast to current methods that create texture maps, the proposed approach involves generating segment-wise procedural material graphs as the appearance representation. This method supports high-quality rendering and offers significant flexibility in editing.

A multimodal approach to cross-lingual sentiment analysis with ensemble of transformer and LLM

Sentiment analysis, vital in natural language processing, determines whether text expresses positive, negative, or neutral sentiments, critical in fields like marketing and politics. Analyzing sentiment in foreign languages is challenging due to lack of labeled data. This study suggests an ensemble model of transformers and a large language model (LLM), translating foreign languages into English for sentiment analysis.

Large Hadron Collider experiment zeroes in on magnetic monopoles

Physicist Joseph Polchinski once deemed the existence of magnetic monopoles a safe bet in yet-to-be-seen physics. The MoEDAL collaboration at the Large Hadron Collider (LHC) continues its quest for these particles, predicted by theories beyond the Standard Model, with recent findings marking significant progress.

Zoogeochemists measure how animals change the chemistry of their environments

Ecologists are delving into zoogeochemistry, studying how animal activities influence ecosystem nutrient cycles and carbon levels. Routine behaviors like foraging and defecation can notably alter environmental dynamics, including greenhouse gas emissions. As climate change disrupts weather patterns, researchers observe shifts in animal behavior, highlighting the emerging field's significance.

Could a rare mutation that causes dwarfism also slow ageing?

Scientists studying ageing and metabolic diseases are intrigued by a rare form of dwarfism affecting only 400–500 individuals globally. Recent studies link this condition to several health benefits, such as reduced risk of diabetes, cancer, and cognitive decline. Additionally, mice with similar dwarfism live around 40% longer than control animals.

What It'll Take to Create 21st-Century Mammoths, Dodos, and Thylacines

Colossal Biosciences, known for its 'de-extinction' endeavors, has made waves with plans to revive species like the woolly mammoth, Tasmanian tiger, and dodo bird. Backed by investments from notable entities like In-Q-Tel, the company has assembled a top team of geneticists, including renowned paleogeneticist Beth Shapiro, to advance its mission of bringing extinct species back to life.
