Quantile Residual Lifetime Regression for Multivariate Failure Time Data

Yu, Tonghui · Xiang, Liming · Jeong, Jong-Hyeon

The quantile residual lifetime (QRL) regression is an attractive tool for assessing covariate effects on the distribution of residual life expectancy, which is often of interest in clinical studies. When the study subjects are exposed to multiple events of interest, the failure times observed for the same subject are p...

Mechanics of large-format Li-ion cell with attenuation-based- and diffraction-CT

Dominik PETZ · Haixing FANG · Anatoliy SENYSHYN · Vladislav KOCHETOV

The inner mechanics of large-format cylindrical 4680-type Li-ion batteries are proposed to be studied non-destructively using high-resolution CT and XRD-CT supplying a pixel resolution below 1 µm to the object with radial dimensions of 46 mm. Studies will be carried out at different states of charge capable of followin...

ReMade Proposal Impact of metals blend and electrochemical cycling on defectivity and lattice resilience in Layered oxides as cathode matei

Sergio BRUTTI · Laura SILVESTRI · Arcangelo CELESTE · Andy FITCH · y 1 más

The aim of this proposal is to elucidate the impact on the long- and short-range of defects accumulation induced by alteration in the stoichiometry of Li-rich layered oxide as well as lithium extraction/insertion in the electrochemical charge/discharge in lithium batteries (LIBs) by X-ray diffraction (XRD), high resolu...

ORBIT: Usage-based admission control for file-level HPC multi-tier storage

Mahni, Hocine · Rubini, Stéphane · Gougeaud, Sébsatien · Deniel, Philippe · y 1 más

Hierarchical storage systems in HPC environments combine a high-performance SSD tier with a high-capacity HDD tier, managed at file granularity by policy engines such as Robinhood. A widely used strategy in such systems is to promote on single access (OSA)—migrating any file on its first miss. While OSA maximizes hit r...

Elucidating structures, mechanisms, and kinetics using time resolved XAS for the continuous catalytic partial oxidation of methane to protec

Andrea BLANKENSHIP · Johannes WIESER · Anastasia MOLOKOVA · Archana RAMAKRISHNAN

We aim to identify the relevant species correlated to high methane-to-methyl-ester conversion activity in Mn/TiO2 catalysts and monitor the behavior and changes in Mn speciation/structure of these materials during reaction using time-resolved XAS. In particular, the influence of the protectant co-feed (used to prevent...

SpaceMind: A modular and self-evolving embodied vision-language agent framework for autonomous on-orbit servicing

Aodi Wu · Haodong Han · Xubo Luo · Ruisuo Wang · y 2 más

Autonomous on-orbit servicing demands embodied agents that perceive through visual sensors, reason about 3D spatial situations, and execute multi-phase tasks over extended horizons. We present SpaceMind, a modular and self-evolving vision-language model (VLM) agent framework that decomposes knowledge, tools, and reason...

Advancement in statistical modelling of chemical impurity profiles in forensic science

Sebastian Jonsson · Lina Mörén · Magnus Engqvist · Marcus Carlsson · y 5 más

At crime scenes, investigators may encounter harmful and illegal chemical substances. Forensic technicians can usually conclude the identity of the chemical substance using proper analytical techniques. However, to tie the chemical substance to a manufacturer is more challenging. Yet, substances usually contain clues o...
