With the massive increase in wireless data traffic in recent years, multi-tier wireless networks have been deployed to provide much higher capacities and coverage. However, heterogeneity of wireless networks bring new challenges for interference analysis and coordination due to spatial randomly distributed transmitters. In this paper, we present a distancedependent interference alignment (IA) a...

In recent years, the population growth rate has been gradually declining in China. As problem becomes increasingly significant, accurate prediction of development trends become a top priority, used to facilitate national scientific planning and effective decision making. Based on historical data spanning period 20 years (1999–2018), this article presents predictions populations 210 prefecture-l...

In Western countries gastric cancer continues to remain a biologically aggressive tumor, with poor long-term oncological outcomes. In Romania, the estimated gastric cancer was the fifth cause of oncological death in men and the eighth cause of oncological death in women in 2012.The objective of the study is to detail when should the hepatoduodenal ligament (station 12) be cleared surgically as ...

This paper addresses the proposal that the number of processed air tracks of a two-tier fusion process can be increased by applying a balanced fusion tree which can balance tracks across local fusion nodes. Every fusion cycle, a fusion process combines duplicate tracks from multiple radars and creates a single integrated air picture (SIAP). The two-tier fusion process divides the fusion process...

We propose a clean slate design for the next generation Internet architecture that allows natural sharing of resources among multiple organizations. Our architecture consists of a 3-tier object model. The bottom tier consists of the network infrastructure owned by multiple Internet service providers. The second tier consists of hosts that may be owned by different organizations. The third tier ...

How will the distribution of welfare, consumption, and leisure across households be affected by social security reform? This paper addresses this question for social security reforms with a two-tier structure by comparing steady states under a realistic version of the current U.S. system and under the two-tier system. The first tier is a mandatory, defined-contribution pension offering a retire...

This article summarizes our approach to the management of children and adults with primary immune thrombocytopenia (ITP) who do not respond to, cannot tolerate, or are unwilling to undergo splenectomy. We begin with a critical reassessment of the diagnosis and a deliberate attempt to exclude nonautoimmune causes of thrombocytopenia and secondary ITP. For patients in whom the diagnosis is affirm...

Mobile sinks play a great role in many Wireless Sensor Network applications for efficient data accumulation, localized sensor reprogramming and for collecting data from various sensor nodes across the globe. However, in sensor networks that make use of the existing three tier security framework, elevates a new security challenge i.e an attacker can easily create a replicated node and can gain c...
