Clustering Based Dynamic Bandwidth Allocation in HC-RAN

A wireless network is composed of several independent nodes or gadgets that communicate mutually through a wireless link. The most destructive challenge encountered in a wireless network is bandwidth allocation because it defines the amount the network will cost and how effectively it will function. The most cutting-edge network architecture in the present wireless communication system, cluster-based heterogeneous cloud radio access networks (HC-RANs), is what powers cloud computing in heterogeneous networks. In this research, we proposed an HC-RANs that may optimize energy consumption for wireless data transfer in the multi-hop device to device scenario. The proposed scheme offers bandwidth allocation in wireless environments where there are concerns about significant user mobility over the course of a given time. The above design, we used clustering with joint beam formation for the down link of heterogeneous cloud radio access network (HC-RAN), developed design to improved amount of FBS. Result outcomes helped in calculating Critical bandwidth usage (CBU)

Biomarker-Based Targeted Therapeutics

Cancer biomarkers are emerging as important tools for disease diagnosis, prediction and prognosis. A significant number of studies have been reported in the field of biomarker discovery due to their potential as personalized targeted therapy. With the converging gap about their utilization as specific targets, studies have focused on identifying disease-specific biomarkers in different cancer types. This chapter provides a comprehensive overview about different cancer-associated biomarkers, their prevalence in different cancer types and their use as targeted therapy. Additionally, we provide an in-sight on the therapeutic and diagnostic potential of different noncoding RNAs as cancer biomarkers

Application of somatic hybridization for the improvement of horticultural crops

Somatic hybridization (SH) using protoplast fusion is a promising tool to produce symmetrical and asymmetrical polyploidy somatic hybrids in many agricultural crops. The technique of SH could facilitate conventional breeding by providing of novel lines so as to use them as elite breeding materials in conventional crosses for both scion and rootstock improvement. Further, SH can overcome those problems associated with sexual hybridization viz., sexual incompatibility, nucellar embryogenesis, and male/female sterility. Successful exploitation of SH in horticultural crops mainly comes from transfer of resistance genes for biotic and abiotic stresses from related species in several horticultural crops, viz., citrus, potato, brinjal, tomato, mango, avocado, banana, strawberry, pear, cherry etc. Unlike transgenic technology, SH is not affected by legal formalities and able to transfer uncloned multiple genes. However, certain boundaries and limitations of SH restricts its use over sexual hybridization but, envisage of new genomic technologies providing better insight into the plant genomes will increase the potentiality of SH in betterment of agriculture

Post-tsunami oceanographic conditions in southern Arabian Sea and Bay of Bengal

Physical oceanographic conditions along the east and west coasts of India immediately after the recent devastating tsunami are presented here. The thermocline in the southeast coast exhibited trivial downward tilt towards north. A mixed layer deepening (>50 m) associated with low-salinity ( 36.0 psu) was identified as the Arabian Sea high salinity water mass along the west coast of India around 100 m depth up to 10°N. The heat content changes closely followed similar changes in the depth of the 20°C isotherm. Turbidity measurements using light scattering sensor showed the existence of two layers of high-scattering, one around 40 m and the other around 250 m. The shallow high-scattering layer is associated with high chlorophyll a concentration, but the deeper high-scattering layer noticed at shallow stations off the west and east coasts of India may be due to the resuspension of the sea-floor sediments due to turbulence generated by the tsunami

Rhabdomyolysis with acute kidney injury after single episode of generalized seizure in a known case of epilepsy: a case report

Rhabdomyolysis is defined as breakdown of skeletal muscle fibers with subsequent release of its cellular components into the circulation. It is associated with variety of causes and status epilepticus is one of it. The excessive muscular activity associated with seizure is possible explanation for it. It is clinically evident by the new onset severe generalized bodyache, weakness and myalgia associated with dark coloured urine. Acute kidney injury is one of the most serious complications associted with rhabdomyolysis. Single episode of generalized seizure is not a frequent cause for rhabdomyolysis. Acute kidney injury due to rhabdomyolysis, following a single episode of seizure is a rare entity. Here we report a case of rhabdomyolysis with acute kidney injury following a single episode of generalized seizure. High index of suspicion is required to timely diagnose and treat such patients. Timely intervention with hemodialysis along with other supportive care can completely revert this potentially serious complication to normal

IMPROVED WEIGHTED CLUSTERING ALGORITHM FOR MOBILE AD HOC NETWORKS

ABSTRACT The proposed weight-based distributed clustering algorithm takes into consideration the ideal degree, transmission power, mobility, and battery power of mobile nodes. We try to keep the number of nodes in a cluster around a pre-defined threshold to facilitate the optimal operation of the medium access control (MAC) protocol. The non-periodic procedure for cluster head election is invoked on-demand, and is aimed to reduce the computation and communication costs. The cluster heads, operating in "dual" power mode, connects the clusters which help in routing messages from a node to any other node. Key words: ad hoc networks, clusters, dominant set, load balancing INTRODUCTION Current wireless cellular networks solely rely on the wired backbone by which all base stations are connected, implying that networks are fixed and constrained to a geographical area with a pre-defined boundary. Deployment of such networks takes time and cannot be set up in times of utmost emergency. Therefore, mobile multihop radio networks, also called ad hoc or peer-to-peer networks, play a critical role in places where a wired (central) backbone is neither available nor eco-nomical to build, such as law enforcement operations, battle field communications, disaster recovery situations, and so on. Such situations demand a network where all the nodes includ-ing the base stations are potentially mobile, and communica-tion must be supported untethered between any two nodes. A multi-cluster, multi-hop packet radio network architecture for wireless systems should be able to dynamically adapt itself with the changing network configurations. Cer-tain nodes, known as clusterheads, are responsible for the formation of clusters each consisting of a number of nodes (analogous to cells in a cellular network) and maintenance of the topology of the network. The set of clusterheads is known as a dominant set. A clusterhead does the resource allocation to all the nodes belonging to its cluster. Due to the dynamic nature of the mobile nodes, their association and dissociation to and from clusters perturb the stability of the network and thus reconfiguration of clusterheads is unavoidable. This is an important issue since frequent clusterhead changes adversely affect the performance of other protocols such as scheduling, routing and resource allocation that rely on it. Choosing clus-terheads optimally is an NP-hard proble

Resource Allocation and Mode Selection in 5G Networks Based on Energy Efficient Game Theory Approach

With the advent of next-generation cellular networks, energy efficiency is becoming increasingly important. To tackle this issue, this paper investigates energy efficiency in D2D-enabled heterogeneous cellular networks. Boosting the longterm energy efficiency of wireless 5G communication networks is being explored through mode selection and resource allocation. The study proposed a three-stage process for energy-efficient mode selection and resource allocation. The process starts with cellular users who switch to D2D emitting a beacon and cellular users within close proximity reacting to it. A proposed auction mechanism will be enacted inside the group in the second state ( in this paper, the group size will be four). Next, each cellular user was classified according to SINR values, distance, and battery life, so that they could dynamically transition between standard cellular mode and D2D mode. For stage three, direct-hop hybrid D2D communication, we developed a TAMM double auction game model that efficiently splits resources. To identify the true bidders in our game model, we compute the median and mode values of the ASK and BID values received by both seller and buyer cellular users. A simulation study shows that the proposed method is energy-efficient in a heterogeneous network enabled by D2D

Fermionic representation for the ferromagnetic Kondo lattice model -- diagrammatic study of spin-charge coupling effects on magnon excitations

A purely fermionic representation is introduced for the ferromagnetic Kondo lattice model which allows conventional diagrammatic tools to be employed to study correlation effects. Quantum 1/S corrections to magnon excitations are investigated using a systematic inverse-degeneracy expansion scheme which incorporates correlation effects in the form of self-energy and vertex corrections, while explicitly preserving the continuous spin-rotation symmetry. Magnon self-energy is studied in the full range of interaction strength, and shown to result in strong magnon damping and anomalous softening for zone boundary modes, which accounts for several zone-boundary anomalies observed in recent spin-wave measurements of ferromagnetic manganites.Comment: 16 pages, 9 figure
