Interpreting estimated observation error statistics of weather radar measurements using the ICON-LAM-KENDA system [PDF]
Assimilation of weather radar measurements including radar reflectivity and radial wind data has been operational at the Deutscher Wetterdienst, with a diagonal observation error (OE) covariance matrix.

The constant false alarm rate (CFAR) detectors are well studied for ship detection in synthetic aperture radar (SAR) images, which suffer performance degradation due to the capture effect from interfering outliers, such as nearby targets, sidelobes, and ...

Efficient Truncated Statistics with Unknown Truncation [PDF]
We study the problem of estimating the parameters of a Gaussian distribution when samples are only shown if they fall in some (unknown) subset $S \subseteq \R^d$. This core problem in truncated statistics has long history going back to Galton, Lee, Pearson and Fisher. Recent work by Daskalakis et al.

The Importance of Weakly Co-Evolving Residue Networks in Proteins is Revealed by Visual Analytics
Small changes in a protein’s core packing produce changes in function, and even small changes in function bias species fitness and survival. Therefore individually deleterious mutations should be evolutionarily coupled with compensating mutations that ...

Technical note: Equilibrium droplet size distributions in a turbulent cloud chamber with uniform supersaturation [PDF]
In a laboratory cloud chamber that is undergoing Rayleigh–Bénard convection, supersaturation is produced by isobaric mixing. When aerosols (cloud condensation nuclei) are injected into the chamber at a constant rate, and the rate of droplet activation is

One recurring difficulty in ecotoxicological studies is that a substantial portion of concentrations are below the limits of detection established by analytical laboratories.

Adaptive trajectory estimation with power limited steering model under perturbation compensation
Trajectory estimation of maneuvering objects is applied in numerous tasks like navigation, path planning and visual tracking. Many previous works get impressive results in the strictly controlled condition with accurate prior statistics and dedicated ...

Remarkable statistical behavior for truncated Burgers–Hopf dynamics [PDF]
A simplified one-dimensional model system is introduced and studied here that exhibits intrinsic chaos with many degrees of freedom as well as increased predictability and slower decay of correlations for the large-scale features of the system. These are important features in common with vastly more complex problems involving climate modeling or ...

Modeling left-truncated and right-censored survival data with longitudinal covariates [PDF]
There is a surge in medical follow-up studies that include longitudinal covariates in the modeling of survival data. So far, the focus has been largely on right-censored survival data.

Spectroscopic Constraints on the Form of the Stellar Cluster Mass Function [PDF]
This contribution addresses the question of whether the initial cluster mass function (ICMF) has a fundamental limit (or truncation) at high masses. The shape of the ICMF at high masses can be studied using the most massive young (
