A deterministic algorithm for experimental design applied to tomographic and microseismic monitoring surveys [PDF]
, 2004 Most general experimental design algorithms are either: (i) stochastic and hence give different designs each time they are run with finite computing power, or (ii) deterministic but converge to results that depend on an initial or reference design ...

Transient Cytoskeletal Anisotropy Encodes Short‐Term Mechanical Memory in Glioblastoma Cells
Advanced Materials, EarlyView.The same mechanical deformation can produce distinct cytoskeletal states depending on loading history. Experiments and constitutive modeling reveal that transient actin–vimentin anisotropy stores mechanical information and governs short‐term mechanical memory in glioblastoma cells.

Modeling Leukemia in Children Using Phase-type Distribution [PDF]
Journal of Kerman University of Medical Sciences, 2017 Background: In this study, with the aim of modeling Leukemia in children using Phase-type distribution, three transitional phases including diagnosis, brain metastasis and testis/ovary metastasis, and one absorotion phase of recovery/death have been ...

Advanced Materials, EarlyView.Applied here for the first time to a 2D material, high‐resolution synchrotron x‐ray Fourier transform holography directly images topological spin textures in Fe3GeTe2. Combined with atomistic tight‐binding simulations including itinerant electrons and Rashba spin‐orbit coupling, the approach reveals labyrinth, skyrmion, and mixed phases, and uncovers ...

Multiple Attribute Learning with Canonical Correlation Analysis and EM algorithm
, 2007 This paper presents a new framework of learning pattern recognition, called "multiple attribute learning ". In usual setting of pattern recognition, target patterns have several attribute such as color, size, shape, and we can classify the ...

Advanced Materials, EarlyView.A mechanochemically synthesized dual‐site electrocatalyst (RuNC@Fe1NC) accelerates alkaline hydrogen evolution via atomic‐level spatial decoupling. Oxophilic Fe single atoms effectively dissociate water, while adjacent Ru nanoclusters rapidly recombine hydrogen.

Analysis of stopping criteria for the EM algorithm in the context of patient grouping according to length of stay [PDF]
, 2008 The expectation maximisation (EM) algorithm is an iterative maximum likelihood procedure often used for estimating the parameters of a mixture model. Theoretically, increases in the likelihood function are guaranteed as the algorithm iteratively improves

Ionic Gating of Liquid‐Crystal‐Like Pteridine Assemblies Enables Tunable Light Scattering
Advanced Materials, EarlyView.Tunable optical properties emerge through developmentally regulated ionic gating, which transforms disordered, ultraviolet (UV)‐absorbing organelles into concentrically ordered, liquid‐crystal‐like light scatterers. By integrating analyses of pteridine composition, potassium‐dependent assembly, hierarchical ultrastructure, and optical behavior, the ...
