Side population (SP) cells, which can be identified by their ability to exclude Hoechst 33342 dye, are one of the candidates for somatic stem cells. Although bone marrow SP cells are known to be long-term repopulating hematopoietic stem cells, there is little information about the characteristics of cardiac SP cells (CSPs). When cultured CSPs from neonatal rat hearts were treated with oxytocin ...

The steadily growing importance of resilience-critical Internet applications leads to a rising number of multi-homed sites and systems. But since the protocols of the classical Internet – particularly TCP – assume a single access path only, the number of programs supporting multiple network paths is still small. The Stream Control Transport Protocol (SCTP), which is an advanced general-purpose ...

Most mobile devices today are equipped with multiple and heterogeneous wireless interfaces. In this paper we ask the following question: What is the best approach to leverage the multiple interfaces available at a mobile device in terms of the performance delivered to the user? In answering the question we argue that simple ‘‘bandwidth aggregation’’ approaches do not provide any meaningful bene...

Simultaneous operation of multiple network interfaces can benefit mobile devices with diverse network interfaces. This paper outlines an IP-level network activation strategy that aims at optimum use of the complementary features of the underlying networks. A key design issue in such strategies is the energy cost of different network interfaces. As a step towards validating and fine-tuning our s...

Modern consumer devices, like smartphones and tablets, have multiple interfaces (e.g., WiFi and 3G) that attach to new access points as users move. These mobile, multi-homed computers are a poor match with an Internet architecture that binds connections to fixed end-points with topology-dependent addresses. As a result, hosts typically cannot spread a connection over multiple interfaces or path...

Handoff performance of NEMO BS protocol with existent improvement proposals is still not sufficient for real time and QoS-sensitive applications and further optimizations are needed. When dealing with single homed NEMO, handoff latency and packet loss become irreducible all optimizations included, so that it is impossible to meet requirements of the above applications. Then, How to combine the ...

Since the 1990s, when late novels of Henry James became a touchstone for ethical turn in literary criticism, critics different persuasions, such as Martha Nussbaum and J. Hillis Miller, homed on certain complex terms ambiguous avowals James’s prose their efforts to hold him up an ‘exemplary’ writer, committed ‘ethical’ values particularity singularity. In doing so, these overlooked prospect tha...

In heterogeneous wireless network environments, network connections of a device may have a significant differential. This paper studies the effect of path bandwidth differential on the performance of fast retransmission strategies in Multi-homing environments. It identifies that fast retransmission on an alternate path may cause receive buffer blocking when path bandwidth differential is signif...

A prerequisite for a widespread and successful deployment of on-demand ad-hoc networking technology is its ability to provide easy access to the Internet. Existing solutions for Internet access are mainly based on modifying Mobile IPv4 (MIPv4). An easier approach, yet poorly documented in published material, is to implement Network Address Translation (NAT) on Internet Gateway nodes in the ad h...

It however relies on a single 802.11 network interface card only, which fails to support simultaneous access of 802.11 and non-802.11 services. As such, mul...
