Microbiological Mechanisms of Sand‐Mixed Soil Improvement in Continuously Cropped Soil

Land Degradation &Development, EarlyView.
ABSTRACT Sand‐mix soil is a widely adopted method for soil improvement in agricultural production. However, beyond the evident enhancement of physical structure, the mechanisms by which sand‐mix soil promotes crop root growth by influencing soil physicochemical properties and microbial communities remain insufficiently understood.

Linear dynamics of semigroups generated by differential operators

Open Mathematics, 2017
During the last years, several notions have been introduced for describing the dynamical behavior of linear operators on infinite-dimensional spaces, such as hypercyclicity, chaos in the sense of Devaney, chaos in the sense of Li-Yorke, subchaos, mixing ...

Allocation of Indivisible Items With a Common Preference Graph: Minimizing Total Dissatisfaction

Networks, EarlyView.
ABSTRACT Allocating indivisible items among a set of agents is a frequently studied discrete optimization problem. In the setting considered in this work, the agents' preferences over the items are assumed to be identical. We consider a very recent measure for the overall quality of an allocation which does not rely on numerical valuations of the items.

Topological phase transition at the interface of a topological with a conventional insulator

Journal of Physics: Condensed Matter, 2020
Abstract We study the topological states which appear at the interface between a topological insulator (TI) and a conventional insulator (CI) using effective Hamiltonians which accurately describe the band structure of the Bi 2 Se 3 ...

Entropy, topological transitivity, and dimensional properties of unique q-expansions [PDF]

, 2018
Let $ M$ be a positive integer and $ q \in (1,M+1].$ We consider expansions of real numbers in base $ q$ over the alphabet $ \{0,\ldots , M\}$. In particular, we study the set $ \mathcal {U}_{q}$ of real numbers with a unique $ q$-expansion, and the set $

Volume Quantization with Flexible Singularities for Hexahedral Meshing

Computer Graphics Forum, EarlyView.
Abstract We present a novel algorithm for quantization and subsequent hexahedral mesh generation from seamless volumetric maps. Quantization is the process of choosing integers that represent the numbers of hexahedral elements to be placed in each region of the volume, and transforming the seamless map into an integer‐grid map matching that choice ...

TRANSITIVITY IN POINT-FREE TOPOLOGY [PDF]

Bulletin of the Australian Mathematical Society, 2009
AbstractThe main purpose of this paper is to develop a point-free notion of topological transitivity. First, we define transitive frame maps and transitive completely prime filters inFrm, the category of frames and frame maps. Then we discuss the relationship between these notions inFrmand the notions of topological transitive and transitive points ...

Uncovering the Dependence of Cascading Failures on Network Topology by Constructing Null Models

Entropy, 2019
Cascading failures are the significant cause of network breakdowns in a variety of complex infrastructure systems. Given such a system, uncovering the dependence of cascading failures on its underlying topology is essential but still not well explored in

CLusterix: A Hybrid Visualization Model for Hierarchically Clustered Networks

Computer Graphics Forum, EarlyView.
Abstract We introduce Clusterix, a novel hybrid visualization model for representing hierarchically clustered networks, which also supports directed and weighted edges. Clusterix offers an integrated view of both the network and its full cluster hierarchy by compactly visualizing the cluster inclusion tree enriched with links of the network.
