Multi-homing is used by Internet Service Providers (ISPs) to connect to the Internet via different network providers. This study develops a routing strategy under multi-homing in the case where network providers charge ISPs according to top-percentile pricing (i.e. based on the hth highest volume of traffic shipped). We call this problem the Top-percentile Traffic Routing Problem (TpTRP). Solut...

This document briefly describes the localized mobility problem and the current edge-based solution of IETF, the NETLMM architecture. We implemented a simplified version of NETLMM under ns2, in which, we tried to integrate the multi-homing feature with the use of SCTP/mSCTP in both data plane and control plane of NETLMM. In the control plane, we try to use mSCTP signaling between the AR and the ...

Objective(s): Cord blood (CB) is known as a valuable source of hematopoietic stem cells (HSC). Identifying strategies that enhance expansion and maintain engraftment and homing capacity of HSCs can improve transplant efficiency. In this study, we examined different culture conditions on ex vivo expansion and homing capacity of CB-HSCs. Materials and Methods: In this study, 4-5 different units o...

Homing sequence derivation for nondeterministic finite state machines (NFSMs) has important applications in software/hardware system testing and verification. Unlike prior methods based on explicit tree-based search, this article we formulate the of a preset/adaptive homing terms quantified Boolean formula (QBF) solving. This formulation exploits compact circuit representation NFSMs QBF encodin...

Google’s Ads Data Infrastructure systems run the multibillion dollar ads business at Google. High availability and strong consistency are critical for these systems. While most distributed systems handle machine-level failures well, handling datacenter-level failures is less common. In our experience, handling datacenter-level failures is critical for running true high availability systems. Mos...

P-element vectors are commonly used to make transgenic Drosophila and generally insert in the genome in a nonselective manner. However, when specific fragments of regulatory DNA from a few Drosophila genes are incorporated into P-transposons, they cause the vectors to be inserted near the gene from which the DNA fragment was derived. This is called P-element homing. We mapped the minimal DNA fr...

To investigate the population dynamics of anadromous Baltic Sea perch Perca fluviatilis (Linnaeus), we studied migratory behaviour (arrival to spawning location) and structure (genetic differentiation) three closely located (<50 km) populations. Spawning migration lasted for 32–80 days, passive integrated transponder tag (PIT-tag) data indicated that displayed reproductive homing. Populations w...

Reasonable trajectory planning is the precondition for parafoil airdrop system to achieve autonomous accurate homing, and safe landing. To successfully realize self-homing of system, a new optimization design scheme proposed in this paper. The based on parafoil’s unique flight control characteristics adopts segmented homing design. current common method faces problem, whereby straight-line dist...

A mobile group I intron containing two ribozyme domains and a homing endonuclease gene (twin-ribozyme intron organization) can integrate by reverse splicing into the small subunit rRNA of bacteria and yeast. The integration is sequence-specific and corresponds to the natural insertion site (homing site) of the intron. The reverse splicing is independent of the homing endonuclease gene, but is d...

Homing is the phenomenon whereby transplanted hematopoietic cells are able to travel to and engraft or establish residence in the bone marrow. Various chemomkines and receptors are involved in the homing of hematopoietic stem cells. This paper outlines the classic homing protocol used in hematopoietic stem cell studies. In general this involves isolating the cell population whose homing needs t...
