Effect of Zn Plating on the Sinterability and Mechanical Properties of Magnesium Powders

Ryo Tsukane, Masahiro Nogawa, Toshiyuki Tanaka

Displacement-plated Zn on Mg powder forms a eutectic liquid during sintering, wetting interparticle contacts, and promoting capillary densification. In simple powder mixtures (5 mass% Zn), the diffusion rate imbalance created Kirkendall voids on the Zn side, leaving pores that acted as stress …

Approximate modeling for supercritical Galton-Watson branching processes with compound Poisson-gamma distribution

Anonymous, Tomoyuki Obuchi, Toshiyuki Tanaka

We study asymptotic properties of supercritical Galton-Watson (GW) branching processes in the asymptotic where the mean of the offspring distribution approaches 1 from above. We show that the population-size distribution of the GW branching processes at a sufficiently large generation in this …

Leveraging pretrained deep protein language model to predict peptide collision cross section

Ayano Nakai-Kasai, Kosuke Ogata, Yasushi Ishihama, Toshiyuki Tanaka

Collision cross section (CCS) of peptide ions provides an important separation dimension in liquid chromatography/tandem mass spectrometry-based proteomics that incorporates ion mobility spectrometry (IMS), and its accurate prediction is the basis for advanced proteomics workflows. This paper describes experimental data and a …

Universality of reservoir systems with recurrent neural networks

Hiroki Yasumoto, Toshiyuki Tanaka

Approximation capability of reservoir systems whose reservoir is a recurrent neural network (RNN) is discussed. We show what we call uniform strong universality of RNN reservoir systems for a certain class of dynamical systems. This means that, given an approximation error to …

Harmonizing Attention: Training-free Texture-aware Geometry Transfer

Eito Ikuta, Yohan Lee, Akihiro Iohara, Y. Saito et autres

Creating images where surface patterns of one object - such as cracks, holes, or grooves - are precisely transferred onto objects made of different materials remains a challenging task in computer graphics. For example, recreating the exact pattern of wood grain cracks …

Negative-Prompt Inversion: Fast Image Inversion for Editing with Text-Guided Diffusion Models

Daiki Miyake, Akihiro Iohara, Yu Saito, Toshiyuki Tanaka

In image editing employing diffusion models, it is crucial to preserve the reconstruction fidelity to the original image while changing its style. Although existing methods ensure reconstruction fidelity through optimization, a drawback of these is the significant amount of time required for …
