Diameter-Aware Extreme Group Queries
In spatial databases, the objects have semantic attributes as well as geographic coordinates. Considering the two aspects, we propose the diameter-aware extreme group query (DiaEG query), which searches for good $k$ -item groups of objects. We mark the

On the structure of support point sets
Let X be a metrizable compact convex subset of a locally convex space. Using Choquet's Theorem, we determine the structure of the support point set of X when X has countably many extreme points. We also characterize the support points of certain families

Studying the Effect of Changes in Dew Point Temperature on Extreme Precipitation in the North West of Iran [PDF]
In the present research, using the daily precipitation data of 479 meteorological and rain gauge stations in the north west of Iran, the relationship between the changes in the dew point temperature and the precipitation in this region was investigated ...

New Rotation Sets in a Family of Torus Homeomorphisms [PDF]
We construct a family $\{\Phi_t\}_{t\in[0,1]}$ of homeomorphisms of the two-torus isotopic to the identity, for which all of the rotation sets $\rho(\Phi_t)$ can be described explicitly.

Bayesian extreme value analysis was used to forecast the optimal point in agricultural commodity futures prices in the United States for cocoa, coffee, corn, soybeans and wheat. Data were collected daily between 2000 and 2020.

Analyzing Spatial Relations of Extreme Precipitations of Western Iran [PDF]
Extreme precipitations at each point are those irregular precipitations which are situated in the trail and away from the focus point of the precipitation frequency distribution of that point.

Lower Bounds of Quantum Search for Extreme Point
We show that Durr-Hoyer's quantum algorithm of searching for extreme point of integer function can not be sped up for functions chosen randomly. Any other algorithm acting in substantially shorter time $o(\sqrt{2^n})$ gives incorrect answer for the ...

Dynamics of doubly stochastic quadratic operators on a finite-dimensional simplex
The present paper focuses on the dynamics of doubly stochastic quadratic operators (d.s.q.o) on a finite-dimensional simplex. We prove that if a d.s.q.o. has no periodic points then the trajectory of any initial point inside the simplex is convergent. We

Extremal dichotomy for uniformly hyperbolic systems [PDF]
We consider the extreme value theory of a hyperbolic toral automorphism $T: \mathbb{T}^2 \to \mathbb{T}^2$ showing that if a H\"older observation $\phi$ which is a function of a Euclidean-type distance to a non-periodic point $\zeta$ is strictly ...

Extreme-Point-based Heuristics for the Three-Dimensional Bin Packing problem [PDF]
One of the main issues in addressing three-dimensional packing problems is finding an efficient and accurate definition of the points at which to place the items inside the bins, because the performance of exact and heuristic solution methods is actually
