Rise In Severity Of Hottest Days Outpaces Global Average Temperature Increase（图）
Hottest Days Outpaces Global Average Temperature Increase
2018/2/1
While our planet’s average annual temperature has increased at a steady pace in recent decades, there has been an alarming jump in the severity of the hottest days of the year during that same period,...
Louisiana wetlands struggling with sea-level rise four times the global average
Louisiana wetlands struggling sea-level rise four times global average
2017/3/30
Without major efforts to rebuild Louisiana’s wetlands, particularly in the westernmost part of the state, there is little chance that the coast will be able to withstand the accelerating rate of sea-l...
Distributed average consensus with least-mean-square deviation
Distributed average consensus Least-mean-square Convex optimization Edge-transitive graphs
2015/8/10
We consider a stochastic model for distributed average consensus, which arises in applications such as load balancing for parallel processors, distributed coordination of mobile autonomous agents, and...
Genetic Analysis of Milk Yield in First-Lactation Holstein Friesian in Ethiopia: A Lactation Average vs Random Regression Test-Day Model Analysis
Dairy Cattle Genetic Parameters Random Regression Test-Day Model Test-Day Records
2016/5/18
The development of effective genetic evaluations and selection of sires requires accurate estimates of genetic parameters for all economically important traits in the breeding goal. The main objective...
Study finds extreme temperature anomalies are warming faster than Earth's average
extreme temperature anomalies warming faster Earth's average
2014/12/30
BLOOMINGTON, Ind. -- It’s widely known that the Earth’s average temperature has been rising. But research by an Indiana University geographer and colleagues finds that spatial patterns of extreme temp...
The total radiant energy, and the average depth of all the photons, in the water column
The total radiant energy the average depth all the photons in the water column
2014/4/2
Using radiative transfer theory I show that for a given waveband, the total radiant energy,Qt, present within the water column (per square meter of surface) is proportional to the scalar irradiance ju...
Average Number of Lattice Points in a Disk

2012/6/29
The difference between the number of lattice points in a disk of radius $\sqrt{t}/2\pi$ and the area of the disk $t/4\pi$ is equal to the error in the Weyl asymptotic estimate for the eigenvalue count...
A Cesaro Average of Hardy-Littlewood numbers
Goldbach-type theorems Hardy-Littlewood numbers Laplace transforms Cesaro averages
2012/6/14
Let $\Lambda$ be the von Mangoldt function and (r_{\textit{HL}}(n) = \sum_{m_1 + m_2^2 = n} \Lambda(m_1),) be the counting function for the Hardy-Littlewood numbers. Let $N$ be a sufficiently large in...
A Cesaro Average of Goldbach numbers
Goldbach-type theorems Laplace transforms Cesaro averages
2012/6/14
Let $\Lambda$ be the von Mangoldt function and (r_G(n) = \sum_{m_1 + m_2 = n} \Lambda(m_1) \Lambda(m_2)) be the counting function for the Goldbach numbers. Let $N \geq 2$ be an integer. We prove that ...
Quadratic congruences on average and rational points on cubic surfaces
Quadratic congruences rational points Manin’s conjecture cubic surfaces universal torsors
2012/5/24
We investigate the average number of solutions of certain quadratic congruences. As an application, we establish Manin's conjecture for a cubic surface whose singularity type is A_5+A_1.

2012/4/18
We consider the functional regular variation in the space $\mathbb{D}$ of c\`adl\`ag functions of multivariate mixed moving average (MMA) processes of the type $X_t = \int\int f(A, t - s) \Lambda (d A...

Separating different propositional proof systems梩hat is, demonstrating that one proof system cannot efficiently simulate another proof system梚s one of the main goals of proof complexity. Nevertheless,...
Average Heating Rate of Hot Atmospheres in Distant Clusters by Radio AGN: Evidence for Continuous AGN Heating
Average Heating Atmospheres Distant Clusters Evidence Continuous Heating
2011/10/9
We examine atmospheric heating by radio active galactic nuclei (AGN) in distant X-ray clusters by cross correlating clusters selected from the 400 Square Degree (400SD) X-ray Cluster survey with radio...
