Simulating convergence properties of BGP [PDF]

Proceedings. Eleventh International Conference on Computer Communications and Networks, 2003
We present a simple BGP simulator that is used for testing convergence properties of inter-domain routing. The discrete-event driven simulator contains a high-level abstraction model of the BGP protocol. The purpose is to perform simulations to examine the complexity of routing information exchange and to test different possible reasons for delayed ...

Expected convergence properties of BGP [PDF]

Computer Networks, 2005
Border gateway protocol (BGP), the de facto standard used for interdomain routing, is a key enabler for interconnecting largely autonomous IP-subnetwork domains into large IP-networks. Since data transfer may not be possible until stable routes are learned, it is not only critical for BGP to converge after any policy or topology changes, but it is ...

Engineering Microbial Particles for Next‐Generation Biomedical Platforms

Advanced Science, EarlyView.
Microbe‐derived particles (MDPs), which include extracellular vesicles, outer membrane vesicles, inclusion bodies, polysaccharide particles, and virus‐like particles, represent a rapidly expanding category of bioinspired nanomaterials. With their natural origin, intrinsic biocompatibility, and highly programmable functionality, MDPs serve as a ...

CSFM: A Novel Framework for Stratigraphic Forward Modeling of Clastic Systems

Geosciences
Stratigraphic forward modeling (SFM) is a numerical approach used to reconstruct sedimentary basin evolution by simulating the infilling and tectonic evolution process of strata.

Q estimation of seismic reflection data and its application in oil and gas exploration

Dizhi lixue xuebao, 2022
In oil and gas seismic exploration, when the seismic wave propagates in the earth medium, it will encounter obvious absorption and attenuation, resulting in the main frequency of the seismic signal shifting to the low-frequency end.

Experimental Study and Theoretical Interpretation of Partial Saturation Effects on P- and S-Wave Velocities and Anisotropy in Artificial Tight Sandstones with Controlled Aligned Fractures

Applied Sciences
This study investigates the combined effects of partial saturation and aligned fractures on P- and S-wave velocities and anisotropy in tight sandstones. Ultrasonic measurements (0.5 MHz) were conducted on three synthetic samples with a matrix porosity of

Evolution of Matrix Gla and Bone Gla Protein Genes in Jawed Vertebrates

Frontiers in Genetics, 2021
Matrix Gla protein (Mgp) and bone Gla protein (Bgp) are vitamin-K dependent proteins that bind calcium in their γ-carboxylated versions in mammals. They are recognized as positive (Bgp) or negative (Mgp and Bgp) regulators of biomineralization in a ...

Tuning the Length of Filomicelles Prepared Via Templated Polymerization‐Induced Self‐Assembly

Small, EarlyView.
High‐aspect‐ratio polymeric micelles are attractive yet notoriously difficult to control in length. We reveal a counterintuitive and powerful solution: in supramolecularly templated PISA, adding non‐sticker polymer unexpectedly elongates the micelles, while post‐assembly sonication enables precise shortening with reduced dispersity.

Taxonomic, Phylogenetic and Functional Diversity of Mammals Across a Nationwide Protected Area Network

Animal Conservation, EarlyView.
Using camera‐trap data from 26 protected across Tanzania, we show that greater landscape heterogeneity and stronger protection are associated with higher mammal species richness and, in turn, functionally and phylogenetically richer mammal assemblages. Greater landscape heterogeneity appears to favour generalist species while stronger protection seems ...

Creative‐class dynamics, technological evolution and growth

Economica, EarlyView.
Abstract This paper investigates the impact of creativity on technological advancement, long‐term economic development, and social welfare, where creativity is determined endogenously through interactions within social networks. The analysis shows that an economy remains stagnant, exhibiting neither networking nor long‐term growth, when the size of the
