Temperature significantly increased and snowfall decreased in the iconic Greater Yellowstone Area since 1950 because of climate change, and these trends will likely continue through the rest of the ce...
New research published by scientists at the Woods Hole Oceanographic Institution shows that polystyrene, one of the world's most ubiquitous plastics, may degrade in decades or centuries when exposed t...
A central goal of the program is to further connections between problems in infinite and finite dimensioQLAWS1_imagenal linear algebra. This workshop will focus on the expected characteristic polynomi...
Seismologists investigating how Earth forms new continental crust have compiled more than 20 years of seismic data from a wide swath of South America’s Andean Plateau and determined that processes the...
Suppose Sn is a sum of n independent and identically distributed random variables with E\Xl\<oom If n is large, Sn is approximately normal. A histogram of k copies of Sn will be close to the ...
A team of researchers from Northeastern University and Oregon State University published results in Nature today investigating the effects of climate change on coastal ocean upwell...
Background: Observational studies showed that circulating L-ascorbic acid (vitamin C) is inversely associated with cardiometabolic traits. However, these studies were susceptible to confounding and re...
Today’s climate models predict a 50 percent increase in lightning strikes across the United States during this century as a result of warming temperatures associated with climate change.
This document derives several expected values related to the parameterized mean model with Gaussian noise and their simplified forms.
In the set of all patterns in $S_n$, it is clear that each k-pattern occurs equally often. If we instead restrict to the class of permutations avoiding a specific pattern, the situation quickly become...
We study the stochastic versions of a broad class of combinatorial problems where the weights of the elements in the input dataset are uncertain. The class of problems that we study includes shortest ...
The ISM evolution of elliptical galaxies experiencing feedback from accretion onto a central black hole was studied recently with high-resolution 1D hydrodynamical simulations including radiative heat...
Abstract: We show the expected order of RNA saturated secondary structures of size $n$ is $\log_4n(1+O(\frac{\log_2n}{n}))$, if we select the saturated secondary structure uniformly at random. Further...
The expected value for the weighted crossing number of a randomly weighted graph is studied. A variation of the Crossing Lemma for expectations is proved. We focus on the case where the edge-weights a...
Inference for the effect of treatment on an outcome often suffers from the unavailability of valid measurements of treatment. Due to this, systematic errors in measurements of treatment occur frequent...
