Studying COVID-19 in light of critical approaches to risk and uncertainty: research pathways, conceptual tools, and some magic from Mary Douglas

open access: yesHealth, Risk and Society, 2020
This editorial is a response to the recent COVID-19 pandemic and underlines the valuable role that critical social science approaches to risk and uncertainty can play in helping us understand how risk is being understood and mitigated.

Anderson Accelerated Douglas-Rachford Splitting [PDF]

open access: yesSIAM Journal on Scientific Computing, 2019
We consider the problem of non-smooth convex optimization with linear equality constraints, where the objective function is only accessible through its proximal operator.

Douglas-Rachford Splitting and ADMM for Nonconvex Optimization: Tight Convergence Results [PDF]

open access: yesSIAM Journal on Optimization, 2017
Although originally designed and analyzed for convex problems, the alternating direction method of multipliers (ADMM) and its close relatives, Douglas-Rachford splitting (DRS) and Peaceman-Rachford splitting (PRS), have been observed to perform ...

Persistence of the Swiss Needle Cast Outbreak in Oregon Coastal Douglas-Fir and New Insights from Research and Monitoring

open access: yesJournal of Forests, 2021
Swiss needle cast (SNC), caused by Nothophaeocryptopus gaeumannii, is a foliage disease of Douglas-fir (Pseudotsuga menziesii), that reduces growth in native stands and exotic plantations worldwide.

Lagrangians for generalized Argyres-Douglas theories [PDF]

open access: yes, 2017
A bstractWe continue the study of Lagrangian descriptions of N=2$$ \mathcal{N}=2 $$ Argyres-Douglas theories. We use our recent interpretation in terms of sequential confinement to guess the Lagrangians of all the Argyres-Douglas models with Abelian ...

Logarithmic W-algebras and Argyres-Douglas theories at higher rank [PDF]

open access: yesJournal of High Energy Physics, 2018
A bstractFamilies of vertex algebras associated to nilpotent elements of simply-laced Lie algebras are constructed. These algebras are close cousins of logarithmic W-algebras of Feigin and Tipunin and they are also obtained as modifications of ...

The structural neural substrates of persistent negative symptoms in first-episode of non-affective psychosis: a voxel-based morphometry study.

open access: yesFrontiers in Psychiatry, 2012
Objectives: An important subset of patients with schizophrenia present clinically significant persistent negative symptoms (PNS). Identifying the neural substrates of PNS could help improve our understanding and treatment of these symptoms. Methods: This

Optogenetic frequency scrambling of hippocampal theta oscillations dissociates working memory retrieval from hippocampal spatiotemporal codes

open access: yesNature Communications, 2023
How temporal coordination of neurons in the hippocampus contributes to memory function is not well understood. Here the authors show that abolishing hippocampal theta oscillations lead to impaired working and episodic memory while leaving spatiotemporal ...

APOE2 is associated with spatial navigational strategies and increased grey matter in the hippocampus

open access: yesFrontiers in Human Neuroscience, 2016
The Apolipoprotein E (APOE) gene has a strong association with Alzheimer’s disease (AD). The ε4 allele is a well-documented genetic risk factor of AD. In contrast, the ε2 allele of the APOE gene is known to be protective against AD.
