We present a transmission power control scheme for RPL, the IPv6 Routing Protocol for Low-power lossy network [9], that controls the routing topology to achieve load balancing in a low-power multihop wireless network. We show that higher-than-required transmission power results in congestion and load balancing problems under heavy traffic, and transmission power cannot be optimized for reliable...

IPv6 Routing Protocol for Low Power and Lossy Networks (RPL) is a routing protocol specifically designed for Low power and Lossy Networks (LLN) compliant with the 6LoWPAN protocol. It currently shows up as an RFC proposed by the IETF ROLL working group. However, RPL has gained a lot of maturity and is attracting increasing interest in the research community. The absence of surveys about RPL mot...

BACKGROUND Spontaneous abortion is considered as the most complex problem during pregnancy. Thrombophilia is resumed as a cause of recurrent pregnancy loss (RPL). Glycoprotein IIIa (GPIIIa) gene is involved in thrombosis and abortion. Angiotensin converting enzyme (ACE) converts angiotensin I to angiotensin II and is involved in thrombosis. The most common polymorphism in this gene is the inser...

The subsequent reproductive outcomes in couples with a history of recurrent pregnancy loss (RPL) associated with chromosome abnormalities or polymorphisms are generally not reported in China. Many RPL carrier couples have decided not to have children. The present study recorded the subsequent delivery, miscarriage, and unpregnancy outcomes of 113 RPL carrier couples and 226 non-carrier couples,...

BACKGROUND Some evidence has shown a relationship between human cytomegalovirus (CMV) infection and pregnancy loss. However, whether recurrent or latent CMV infection or altered immune response to CMV is related to recurrent pregnancy loss (RPL) is unclear. We evaluated CMV infection and avidity of antibodies to CMV in women with RPL. MATERIALS AND METHODS This case-control study was conducte...

AIM The aim of this study was to determine plasma Growth Arrest Specific Protein 6 (GAS6) protein levels in patients with unexplained recurrent pregnancy loss (RPL) and compare them to those of pregnant and to healthy non-pregnant women with a history of at least one live delivery. PATIENTS AND METHODS A total of 205 women were included in the study. Of these, 68 were diagnosed with unexplain...
