Technical Considerations for B (BPL) Communi
نویسنده
چکیده
The use of the electric power transmission and distribution system as a transmission medium for broadband communications is considered. It is found that there are three significant technical hurdles to be overcome before successful implementation of such systems can be accomplished. The first is the relatively high attenuation rate due to discontinuities such as taps, transformers and other devices connected to the system. The second is the relatively high background noise on power lines. The third is government regulated limitation on transmitted power for the unlicensed systems that use the power system as a communications medium.

Broadband Transmission Characteristics of Overhead High-voltage Power Line Communi- Cation Channels
This paper considers broadband signal transmission via high-voltage/broadband over power lines (HV/BPL) channels associated with overhead power transmission. To determine the end-to-end channel characteristics of various overhead HV/BPL multiconductor transmission line (MTL) configurations, the chain scattering matrix or T -Matrix (TM) method is adopted. The overhead HV/BPL transmission channel...

A 2015 Lancet paper by Patel et al. on healthcare access in India comprehensively discussed national health programmes where some benefits are linked with the country's Below Poverty Line (BPL) registration scheme. BPL registration aims to support poor families by providing free/subsidised healthcare. Technical issues in obtaining BPL registration by poor families have been previously reported ...

The identification of SYK as a master regulator of apoptosis controlling the activation of the PI3-K/AKT, NFκB, and STAT3 pathways-three major anti-apoptotic signaling pathways in B-lineage leukemia/lymphoma cells-prompts the hypothesis that rationally designed inhibitors targeting SYK may overcome the resistance of malignant B-lineage lymphoid cells to apoptosis and thereby provide the foundat...
متن کاملLow Dose Total Body Irradiation Combined With Recombinant CD19-Ligand × Soluble TRAIL Fusion Protein is Highly Effective Against Radiation-resistant B-precursor Acute Lymphoblastic Leukemia in Mice☆
In high-risk remission B-precursor acute lymphoblastic leukemia (BPL) patients, relapse rates have remained high post-hematopoietic stem cell transplantation (HSCT) even after use of very intensive total body irradiation (TBI)-based conditioning regimens, especially in patients with a high "minimal residual disease" (MRD) burden. New agents capable of killing radiation-resistant BPL cells and s...
متن کاملCD22ΔE12 as a molecular target for RNAi therapy.
B-precursor acute lymphoblastic leukaemia (BPL) is the most common form of cancer in children and adolescents. Our recent studies have demonstrated that CD22ΔE12 is a characteristic genetic defect of therapy-refractory clones in paediatric BPL and implicated the CD22ΔE12 genetic defect in the aggressive biology of relapsed or therapy-refractory paediatric BPL. The purpose of the present study i...
