All hits all the time: parameter-free calculation of spaced seed sensitivity

D. Y.F. Mak, G. Benson
2008 Bioinformatics  
We expect this method to greatly facilitate the study of spaced seed sensitivity and the use of alternative definitions of optimality.  ...  Only the weights assigned to those alignments change. Therefore, if we know all the hits, we can easily (and quickly) find optimal seeds.  ...  In section 6 we show results from applying our parameter free calculation to several seed classes.  ...

Time-aware Entity Alignment using Temporal Relational Attention

Chengjin Xu, Fenglong Su, Bo Xiong, Jens Lehmann
2022 Proceedings of the ACM Web Conference 2022  
We first map entities, relations and timestamps into an embedding space, and the initial feature of each entity is represented by fusing the embeddings of its connected relations and timestamps as well  ...  Experimental results show that our method outperforms the state-of-the-art EA methods.

Time Really Passes, Science Can't Deny That [chapter]

Nicolas Gisin
2017 Time in Physics  
In particular, I argue that besides the geometric time, there is creative time, when objective chance events happen. The existence of the latter follows straight from the existence of free-will.  ...  Today's science provides quite a lean picture of time as a mere geometric evolution parameter. I argue that time is much richer.  ...  Thanks are due to Chris Fuchs who introduced me to Jules Lequyer and to many participants to the workshop on Time in Physics organized at the ETH-Zurich by Sandra Rankovic, Daniela Frauchiger and Renato  ...

First Detection Of Low Energy Electron Neutrinos In Liquid Argon Time Projection Chambers

Corey Adams, Bonnie Fleming, Ornella Palamara
2016 Zenodo  
Liquid argon time projection chambers are the forefront of neutrino detection technology, and the detector of choice for both short and long baseline neutrino oscillation experiments.  ...  This work presents the first experimental observation and study of electron neutrinos in the 1-10 GeV range, the essential oscillation energy regime for the above experiments.  ...  The free ionization density along the track can be sampled by the hit amplitude to the track pitch length ratio (Q f ree /δx), which allows calculating the value of the R factor.  ...
