Machine Learning Clifford invariants of ADE Coxeter elements
No full textThere has been recent interest in novel Clifford geometric invariants of
linear transformations. This motivates the investigation of such invariants for
a certain type of geometric transformation of interest in the context of root
systems, reflection groups, Lie groups and Lie algebras: the Coxeter
transformations. We perform exhaustive calculations of all Coxeter
transformations for , and for a choice of basis of simple
roots and compute their invariants, using high-performance computing. This
computational algebra paradigm generates a dataset that can then be mined using
techniques from data science such as supervised and unsupervised machine
learning. In this paper we focus on neural network classification and principal
component analysis. Since the output -- the invariants -- is fully determined
by the choice of simple roots and the permutation order of the corresponding
reflections in the Coxeter element, we expect huge degeneracy in the mapping.
This provides the perfect setup for machine learning, and indeed we see that
the datasets can be machine learned to very high accuracy. This paper is a
pump-priming study in experimental mathematics using Clifford algebras, showing
that such Clifford algebraic datasets are amenable to machine learning, and
shedding light on relationships between these novel and other well-known
geometric invariants and also giving rise to analytic results.Comment: v1: 34 pages, 16 Figures, 12 Tables. v2: Typos corrected and some

Letter from Clifford I. Uyeda to Aiko HerzigYoshinaga, January 11, 1988
No full textA passionate letter from Clifford Uyeda to Aiko HerzigYoshinaga about the Japanese American Citizens League (JACL) refusing to take a position on people who were arrested because of an allegation that they were involved with the Palestinian Liberation Organization. Uyeda argues that these people are being targeted for incarceration merely because of their ethnicity and that it is important for the JACL to take a stand against government actions that deprive people of liberty based on their race.These materials are from box 73 and 74 of the Frank Chin Papers.

The age-related risk of co-existing meningitis in children with urinary tract infection
No full textObjective: The primary aim of this study was to determine age-stratified rates of co-existing bacterial meningitis in children with urinary tract infection (UTI). The secondary aims of this study were to determine the causative pathogens of UTI, and the clinical features and outcome of children with co-existing meningitis.Methods: Analysis of data collected over a nine-year period at a tertiary pediatric hospital in Australia. Study population: children below 16 years of age with culture-confirmed UTI and a paired CSF sample.Results: A total of 748 episodes in 735 cases were included in the final analysis. The commonest pathogens causing UTI were Escherichia coli (67.4%), Enterococcus faecalis (8.4%), Klebsiella oxytoca (3.5%) and Klebsiella pneumoniae (3.5%). Only two (1.2%; 95% CI: 0.15–4.36%) of 163 neonates (between 0 and 28 days of age) with UTI had co-existing meningitis. Both presented with pyrexia, irritability and lethargy, and recovered uneventfully with antibiotic treatment. There were no cases of co-existing meningitis among 499 infants (between 29 days and 12 months of age) with UTI (95% CI: 0.00–0.74%), or any of the 86 children aged 12 months or over (95% CI: 0.00–4.20%).Conclusions: These findings indicate that clinicians should have a low threshold to perform a lumbar puncture in neonates with UTI, as the risk of co-existing meningitis is not insignificant in this age group. In contrast, beyond the neonatal period, the risk is small and a more selective approach is warranted
Representations of the multi-qubit Clifford group
No full textThe q-qubit Clifford group, that is, the normalizer of the q-qubit Pauli group in U(2q), is a fundamental structure in quantum information with a wide variety of applications. We characterize all irreducible subrepresentations of the two-copy representation φ⊗2 of the Clifford group on the two-fold tensor product of the space of linear operators M2q⊗2. In the companion paper [Helsen et al., e-print arXiv:1701.04299 (2017)], we apply this result to improve the statistics of randomized benchmarking, a method for characterizing quantum systems.Accepted Author ManuscriptQuantum Information and SoftwareQuantum Internet Divisio
