Statistics and dynamics of blockings with a point vortex model [PDF]
Tellus A: Dynamic Meteorology and Oceanography, 2018 We investigate a reduced point vortex model for statistical and dynamical analyses of atmospheric blocking phenomena. Thereby, we consider High-over-low and Omega blocking as relative equilibria of two and three point vortices. Under certain conditions, such point vortex systems move westward opposing the mean westerly flow and hence can become ...

Forward and backward blocking in statistical learning [PDF]
PLOS ONE, 2022 AbstractPrediction errors have a prominent role in many forms of learning. For example, in reinforcement learning, agents learn by updating the association between states and outcomes as a function of the prediction error elicited by the event. One paradigm often used to study error-driven learning is blocking.

Statistics of Random Permutations and the Cryptanalysis of Periodic Block Ciphers [PDF]
Cryptologia, 2012 A block cipher is intended to be computationally indistinguishable from a random permutation of appropriate domain and range. But what are the properties of a random permutation? By the aid of exponential and ordinary generating functions, we derive a series of collolaries of interest to the cryptographic community.

The statistical building blocks of animal movement simulations [PDF]
Movement Ecology, 2023 AbstractAnimal movement plays a key role in many ecological processes and has a direct influence on an individual’s fitness at several scales of analysis (i.e., next-step, subdiel, day-by-day, seasonal). This highlights the need to dissect movement behavior at different spatio-temporal scales and develop hierarchical movement tools for generating ...

Nonparametric estimation over shrinking neighborhoods: Superefficiency and adaptation [PDF]
, 2005 A theory of superefficiency and adaptation is developed under flexible performance measures which give a multiresolution view of risk and bridge the gap between pointwise and global estimation.

$K$ block set partition patterns and statistics
, 2020 A set partition $ $ of $[n]=\{1,\cdots ,n\}$ contains another set partition $ $ if a standardized restriction of $ $ to a subset $S\subseteq[n]$ is equivalent to $ $. Otherwise, $ $ avoids $ $. Sagan and Goyt have determined the cardinality of the avoidance classes for all sets of patterns on partitions of $[3]$.

Statistics of Blocks in k-Divisible Non-Crossing Partitions [PDF]
The Electronic Journal of Combinatorics, 2012 We derive a formula for the expected number of blocks of a given size from a non-crossing partition chosen uniformly at random. Moreover, we refine this result subject to the restriction of having a number of blocks given.Furthermore, we generalize to $k$-divisible partitions.

Between two stools: preclinical research, reproducibility, and statistical design of experiments
BMC Research Notes, 2022 Translation of animal-based preclinical research is hampered by poor validity and reproducibility issues. Unfortunately, preclinical research has ‘fallen between the stools’ of competing study design traditions.

Interference Analysis for mmWave Automotive Radar Considering Blockage Effect
Sensors, 2021 Due to the increasing number of vehicles equipped with millimeter wave (mmWave) radars, interference among automotive radars is becoming a major issue. This paper explores the automotive radar interference in both two-lane and multi-lane scenarios using ...
