An Intrinsic Value System for Developing Multiple Invariant Representations with Incremental Slowness Learning

open access: yesFrontiers in Neurorobotics, 2013
Curiosity Driven Modular Incremental Slow Feature Analysis (CD-MISFA;~cite{cdmisfa}) is a recently introduced model of intrinsically-motivated invariance learning, which shows how curiosity enables the orderly formation of multiple stable sensory ...

A Rescorla-Wagner drift-diffusion model of conditioning and timing. [PDF]

open access: yesPLoS Computational Biology, 2017
Computational models of classical conditioning have made significant contributions to the theoretic understanding of associative learning, yet they still struggle when the temporal aspects of conditioning are taken into account.

Classical and Umbral Moonshine: Connections and $p$-adic Properties [PDF]

open access: yes, 2014
The classical theory of monstrous moonshine describes the unexpected connection between the representation theory of the monster group $M$, the largest of the simple sporadic groups, and certain modular functions, called Hauptmodln. In particular, the $n$

Chiral Observables and Modular Invariants

open access: yes, 1999
Various definitions of chiral observables in a given Moebius covariant two-dimensional theory are shown to be equivalent. Their representation theory in the vacuum Hilbert space of the 2D theory is studied.

In vitro models of cancer‐associated fibroblast heterogeneity uncover subtype‐specific effects of CRISPR perturbations

open access: yesMolecular Oncology, EarlyView.
Development of therapies targeting cancer‐associated fibroblasts (CAFs) necessitates preclinical model systems that faithfully represent CAF–tumor biology. We established an in vitro coculture system of patient‐derived pancreatic CAFs and tumor cell lines and demonstrated its recapitulation of primary CAF–tumor biology with single‐cell transcriptomics ...

Modular Representation Theory of Blocks with Trivial Intersection Defect Groups [PDF]

open access: yesAlgebras and Representation Theory, 2005
The main results of this paper are as follows. Let \(B\) be a \(p\)-block of a finite group~\(G\) such that any two defect groups of~\(B\) intersect in \(O_p(G)\). Then Uno's refinement of Dade's projective conjecture holds. An immediate consequence is that Dade's projective conjecture, Robinson's conjecture, Alperin's weight conjecture, the Isaacs ...

Modular transport in two-dimensional conformal field theory

open access: yesJournal of High Energy Physics
We study the quantum transport generated by the bipartite entanglement in two-dimensional conformal field theory at finite density with the U(1) × U(1) symmetry associated to the conservation of the electric charge and of the helicity.

A non-unitary bulk-boundary correspondence: Non-unitary Haagerup RCFTs from S-fold SCFTs

open access: yesSciPost Physics
We introduce a novel class of two-dimensional non-unitary rational conformal field theories (RCFTs) whose modular data are identical to the generalized Haagerup-Izumi modular data.

Kazhdan--Lusztig-dual quantum group for logarithmic extensions of Virasoro minimal models

open access: yes, 2007
We derive and study a quantum group g(p,q) that is Kazhdan--Lusztig-dual to the W-algebra W(p,q) of the logarithmic (p,q) conformal field theory model. The algebra W(p,q) is generated by two currents $W^+(z)$ and $W^-(z)$ of dimension (2p-1)(2q-1), and ...

Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

open access: yesMolecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...
