A model system created by stacking a pair of monolayer semiconductors is giving physicists a simpler way to study confounding quantum behavior, from heavy fermions to exotic quantum phase transitions.
A curious thing happened when MIT researchers Adam Vernon and Ronald Garcia Ruiz, along an international team of scientists, recently performed an experiment in which a sensitive laser spectroscopy te...

MORPHOLOGICAL MOMENTS OF BINARY IMAGES
Morphological Moments Disc Cover Medial Representation Continuous Skeleton Radial Function Bicircle
2017/6/19
The concept of morphological moments of binary images is introduced. Morphological moments can be used as a shape descriptor combining an integral width description of an object with a description of ...
Predicting the Functional Roles of Knee Joint Muscles from Internal Joint Moments
KNEE JOINT STABILITY MUSCLE ACTIVITY LOWER LIMB KINETICS HEALTHY CONTROLS PARTIAL LEAST SQUARES REGRESSION
2018/4/24
Introduction Knee muscles are commonly labeled as flexors or extensors and aptly stabilize the knee against sagittal plane loads. However, how these muscles stabilize the knee against adduction–abduct...
Electroabsorption (Stark Effect) Spectroscopy of Mono-and Biruthenium Charge-Transfer Complexes:Measurements of Changes in Dipole Moments and Other Electrooptic Properties

Electroabsorption (Stark effect) spectra are reported for the charge-transfer transitions of (NH3)5RuL2+ and [(NH3)5Ru]2L4+,5+, where L is pyrazine (pz) or 4,4'-bipyridine (4,4'-bpy). The spectra perm...
Acute Effects of Foot Rotation in Healthy Adults during Running on Knee Moments and Lateral-Medial Shear Force
Osteoarthritis cartilage biomechanics gait
2016/3/11
As runners age, the likelihood of developing osteoarthritis (OA) significantly increases as 10% of people 55+ have symptomatic knee OA while 70% of people 65+ have radiographic signs of knee OA. The l...
Direct Regression Modelling of High-order Moments in Big Data
Big data Higher-order moment U-statistics Estimating equation Divide-and-conquer
2016/1/26
Big data problems present great challenges to statisti-cal analyses, especially from the computational side. In this paper, we consider regression estimation of high-order mo-ments in big data problem...

Saddlepoint Approximation for Moments of Random Variables
Saddlepoint Approximation Higher moments Sums of i.i.d.ran- dom variables
2016/1/19
In this paper we introduce a saddlepoint approximation method for higher-order moments like E(S − a) m+ ,a > 0, where the random variable S in these expectations could be a single random variabl...
Moments-Correlating DPA
2016/1/9
We generalize correlation-enhanced power analysis collision
attacks into moments-correlating DPA. The resulting distinguisher is applicable
to the profiled and non-profiled (collision) settings and ...
MULTILEVEL OBJECT BASED IMAGE CLASSIFICATION OVER URBAN AREA BASED HIERARCHICAL IMAGE SEGMENTATION AND INVARIANT MOMENTS
hierarchical segmentation shape object-based classification invariant moments
2015/11/16
With the availability of very high resolution multispectral imagery from sensors such as IKONOS and Quickbird, it is possible to
identify small-scale features in urban environment. Because of the mu...
Fractional diffusion limit for collisional kinetic equations:A moments method
Kinetic equations linear Boltzmann equation asymptotic analysis diffusion limit anomalous diffusion limit fractional diffusion relaxation equation anomalous diffusive time scale
2015/10/15
This paper is devoted to hydrodynamic limits of linear kinetic equations. We consider situations in which the thermodynamical equilibrium is described by a heavy-tail distribution function rather than...
CONVERGENCE OF MOMENTS FOR DISPERSING BILLIARDS WITH CUSPS
Chaos decay of correlations Central Limit Theorem
2015/9/29
Dispersing billiards with cusps are deterministic dnamical systems with a mild degree of chaos, exhibiting “intermittent” behavior that alternates between regular and chaotic paterns.
The chapter discusses generalized method of moments (GMM) estimation
methods for spatial models. Much of the discussion is on GMM estimation of
Cliff-Ord-type models where spatial interactions are m...
