Self‐Cooling Molecular Spin Qudits
Advanced Materials, EarlyView.A material made of [GdEr] molecular dimers can encode a qudit and perform as a magnetic refrigerant. Microwave resonant pulses coherently manipulate its 16 spin states, while direct demagnetization measurements cool the material and a device down to temperatures below 1 K.

A Gradient Algorithm Locally Equivalent to the Em Algorithm [PDF]
Journal of the Royal Statistical Society Series B: Statistical Methodology, 1995 SUMMARY In many problems of maximum likelihood estimation, it is impossible to carry out either the E-step or the M-step of the EM algorithm. The present paper introduces a gradient algorithm that is closely related to the EM algorithm.

Mechanically Programmable DNA Hydrogel Microparticles for 3D Cellular Systems
Advanced Materials, EarlyView.DNA hydrogel microparticles are designed to exhibit controllable viscoelasticity and stiffness across three orders of magnitude from 30Pa$30 \,\mathrm{Pa}$ to 6.5kPa$6.5 \,\mathrm{kPa}$. They are uptaken into fibroblast spheroids where they are actively remodeled by cellular forces depending on their mechanical properties.

Spectrum adapted expectation-maximization algorithm for high-throughput peak shift analysis
Science and Technology of Advanced Materials, 2019 We introduce a spectrum-adapted expectation-maximization (EM) algorithm for high-throughput analysis of a large number of spectral datasets by considering the weight of the intensity corresponding to the measurement energy steps.

Tracking with the EM Contour Algorithm [PDF]
, 2002 A novel active-contour method is presented and applied to pose refinement and tracking. The main innovation is that no "features" are detected at any stage: contours are simply assumed to remove statistical dependencies between pixels on opposite sides of the contour.

Belief Revision and the EM Algorithm [PDF]
, 2016 This paper provides a natural interpretation of the EM algorithm as a succession of revision steps that try to find a probability distribution in a parametric family of models in agreement with frequentist observations over a partition of a domain. Each step of the algorithm corresponds to a revision operation that respects a form of minimal change. In
