Calculations consider how a dozen metals such as titanium combine with nitrogen or carbon to form bonds

Experimental analysis and computer simulations reveal how woven fabric composite materials are deformed by heat.

To address the lack of suitable training data for deep-learning semantic segmentation models in urban landscaping, researchers from Osaka University developed a method that generates a training dataset without the need for real images or a model of an existing city. The method, which is based on procedural modelling and image-to-image techniques, enables segmentation models to achieve comparable performance under some conditions at a fraction of the cost of real dataset generation.

Researchers at The University of Tokyo simulated fractures in amorphous materials due to both cyclic fatigue and constant stress using course-grained dynamics, and demonstrated various failure modes, which can help improve reliability of materials

To automatically generate data for training deep convolutional neural network models to segment building facades, researchers from Osaka University used a three-dimensional model and game engine to generate digital city twin synthetic training data. They found that a model trained on these data mixed with some real data was competitive with a model trained on real data alone, revealing the potential of digital twin data to improve accuracy and replace costly manually annotated real data.

When the evolution of towns and of roads are modeled together, the natural landscape alone is enough to predict the actual arrangement of real towns.

Scientists predict that continued global warming under current trends could lead to an elevation of the sea level by as much as five meters by the year 3000 CE.

Researchers have developed a general quantum algorithm that can directly calculate the energy difference of an atom and molecule using a quantum computer. By avoiding the need to calculate the total molecular energies, the general algorithm is expected to be applied not only to quantum chemical calculations but also to various physical and mathematical problems, which are intractable with nowadays classical computers.

High-resolution genome structural analyses combined with large-scale simulations show the arrangements of the genome’s spool-like structures affecting gene expression.

As the move towards open science progresses, the relevance of data sharing and data management increases. In a survey of more than 1,000 researchers in Japan, 95% say they are sharing research data, but a majority of them share only privately among their peers.

A systematic approach to selecting and configuring statistical models improves predictions of extreme events.
