Effects of forest fragmentation on the vertical stratification of neotropical bats [PDF]

open access: yes, 2020
Vertical stratification is a key component of the biological complexity of rainforests. Understanding community- and species-level responses to disturbance across forest strata is paramount for evidence-based conservation and management.

Research on key technology of jacking cable tunnel construction in mudstone and gravel composite stratum

open access: yesIOP Conference Series: Materials Science and Engineering, 2020
Abstract In this paper, the key technology of jacking cable tunnel construction in mudstone and gravel composite stratum is studied. According to the conditions of the jacking cable tunnel crossing the mudstone gravel composite stratum, the selection of the jacking method, the design of the relay and the construction technology of the ...

An Additive Basis for the Chow Ring of \bar{M}_{0,2}(P^r,2) [PDF]

open access: yes, 2007
We begin a study of the intersection theory of the moduli spaces of degree two stable maps from two-pointed rational curves to arbitrary-dimensional projective space.

Overpressure Generation Mechanism in the Jurassic Formations of the Fukang Sag, Junggar Basin: Its Significance for Deep Petroleum Exploration

open access: yesGeosciences
The Jurassic reservoirs in the Fukang Sag of the Junggar Basin exhibit heterogeneous overpressure. As the mechanisms underlying overpressure generation remain poorly constrained, this poses challenges for accurate pre-drilling-pressure prediction and ...

Mechanism of Overlying Strata Structure Instability during Mining below Unconsolidated Confined Aquifer and Disaster Prevention

open access: yesApplied Sciences, 2021
There is a layer of the unconsolidated confined aquifer (UCA) made of non-cemented sand and grit on the bed of Quaternary thick topsoil in many coal mines in east and north China.

Convergence of Siegel-Veech constants

open access: yes, 2017
We show that for any weakly convergent sequence of ergodic $SL_2(\mathbb{R})$-invariant probability measures on a stratum of unit-area translation surfaces, the corresponding Siegel-Veech constants converge to the Siegel-Veech constant of the limit ...

Dynamic evaluation on sealing capacity of caprocks of the Meso-Neoproterozoic reservoirs in Ordos Basin, China

open access: yesEnergy Geoscience
The Meso-Neoproterozoic is a new play in the Ordos Basin. A deeper understanding about the dynamic relationship between the caprocks and the source rocks is needed.

Network-wide Configuration Synthesis

open access: yes, 2017
Computer networks are hard to manage. Given a set of high-level requirements (e.g., reachability, security), operators have to manually figure out the individual configuration of potentially hundreds of devices running complex distributed protocols so ...

Filtered screens and augmented Teichm\"uller space [PDF]

open access: yes, 2015
We study a new bordification of the decorated Teichm\"uller space for a multiply punctured surface F by a space of filtered screens on the surface that arises from a natural elaboration of earlier work of McShane-Penner.
