Better Tradeoffs for Exact Distance Oracles in Planar Graphs
, 2017 We present an $O(n^{1.5})$-space distance oracle for directed planar graphs that answers distance queries in $O(\log n)$ time. Our oracle both significantly simplifies and significantly improves the recent oracle of Cohen-Addad, Dahlgaard and Wulff ...

Immersive reality capabilities of relieving hiraeth
Journal of the Association for Information Science and Technology, EarlyView.Abstract Understanding how immersive experiences foster a sense of presence sufficient to rival real‐world experiences remains an open research area. Prior work has largely examined episodic memory recall in simulated environments, but less is known about how immersive technologies can reconnect individuals with personal memories.

Aggregation of Affine Estimators
, 2013 We consider the problem of aggregating a general collection of affine estimators for fixed design regression. Relevant examples include some commonly used statistical estimators such as least squares, ridge and robust least squares estimators.

British Journal of Clinical Pharmacology, EarlyView.Aim A prior non‐randomized study suggests that potassium supplementation may improve survival among furosemide initiators, and a randomized trial suggests that salt substitutes containing potassium might lower stroke risk. We conducted a retrospective cohort study using health‐care data to confirm or refute these associations among new users of ...

Stochastic Intermediate Gradient Method for Convex Problems with Inexact Stochastic Oracle [PDF]
, 2015 In this paper we introduce new methods for convex optimization problems with inexact stochastic oracle. First method is an extension of the intermediate gradient method proposed by Devolder, Glineur and Nesterov for problems with inexact oracle.

Chemistry – A European Journal, EarlyView.Machine‐learning potentials are increasingly taking on the exploratory tasks of homogeneous catalysis, enabling rapid conformer sampling and reaction‐space mapping. However, when selectivity depends on subtle electronic effects, electronic‐structure methods remain essential.

A New Reduction from Search SVP to Optimization SVP [PDF]
, 2012 It is well known that search SVP is equivalent to optimization SVP. However, the former reduction from search SVP to optimization SVP by Kannan needs polynomial times calls to the oracle that solves the optimization SVP.
