Stable Matching based Resource Allocation for Service Provider\u27s Revenue Maximization in 5G Networks

5G technology is foreseen to have a heterogeneous architecture with the various computational capability, and radio-enabled service providers (SPs) and service requesters (SRs), working altogether in a cellular model. However, the coexistence of heterogeneous network model spawns several research challenges such as diverse SRs with uneven service deadlines, interference management, and revenue maximization of non-uniform computational capacities enabled SPs. Thus, we propose a coexistence of heterogeneous SPs and SRs enabled cellular 5G network and formulate the SPs\u27 revenue maximization via resource allocation, considering different kinds of interference, data rate, and latency altogether as an optimization problem and further propose a distributed many-to-many stable matching-based solution. Moreover, we offer an adaptive stable matching based distributed algorithm to solve the formulated problem in a dynamic network model. Through extensive theoretical and simulation analysis, we have shown the effect of different parameters on the resource allocation objectives and achieves 94 percent of optimum network performance

Inter-Landau-level Andreev Reflection at the Dirac Point in a Graphene Quantum Hall State Coupled to a NbSe2 Superconductor

Superconductivity and quantum Hall effect are distinct states of matter occurring in apparently incompatible physical conditions. Recent theoretical developments suggest that the coupling of quantum Hall effect with a superconductor can provide a fertile ground for realizing exotic topological excitations such as non-abelian Majorana fermions or Fibonacci particles. As a step toward that goal, we report observation of Andreev reflection at the junction of a quantum Hall edge state in a single layer graphene and a quasi-two dimensional niobium diselenide (NbSe2) superconductor. Our principal finding is the observation of an anomalous finite-temperature conductance peak located precisely at the Dirac point, providing a definitive evidence for inter-Landau level Andreev reflection in a quantum Hall system. Our observations are well supported by detailed numerical simulations, which offer additional insight into the role of the edge states in Andreev physics. This study paves the way for investigating analogous Andreev reflection in a fractional quantum Hall system coupled to a superconductor to realize exotic quasiparticles.Comment: published verio

Rejuvenation of Wild Ber (\u3cem\u3eZizyphus\u3c/em\u3e Species) through Budding at Farmer’s Field

Ber is mainly cultivated for its fresh fruits, which are rich in vitamins C, A and B complex. Due to its nutritional qualities it is called poor man’s apple (Gajbhiya et al., 2003). A large number of wild ber shrubs (Zizyphus mauritiana, Z. rotundifolia and Z. nummularia) were seen growing on the neglected lands, uncultivated lands, roadsides and farm boundaries in Kadesara Kala Village in Lalitpur district of Uttar Pradesh (India). Production potential of this species is very low because of poor upkeep and inferior genetic makeup. But they have extensive root system which can withstand prolonged drought and has capability to regenerate even if the shoot system is damaged completely (Batahr, 1990). They are also responsibly resistant to common insect and pest. Therefore, these species offer an excellent production potential from the degraded lands of Bundelkhand region of India (Sharma and Tiwari, 1994; Tiwari and Sharma, 1993) after in-situ budding with improved cultivars. It also provides sufficient leaf biomass (pala) which can be utilized as fodder in lean period and also suitable for hay and silage for goat as it contains 11-13 percent crude protein (Tewatia and Khirwar, 2002). Pruned twigs/stems of ber also meet, to some extent, the fuel wood requirement in rural areas (Kumar et al., 2004)

Economics of BN Hybrid Grass Production Bundelkhand Region of India: A Case Study

Napier grass is also called as Elephant Grass due to its tallness and vigorous vegetative growth. The plants tiller freely and a single clump may produce more than 60 tillers under favorable climatic and soil conditions. Unfortunately, the grass coarse-textured, the leaf blade sheaths as well as sharply serrated, leaf margins. Therefore, cross was made between Bajra which is more succulent, leafy, fine-textured, palatable, fast growing and drought resistant and Napier to combine these qualities with its high yielding potential. The outcome Hybrid Napier is a perennial grass which can be retained on field for 2-3 years. Hybrid napier grass are mostly grown under assured water supply but cultivating under varying agroclimatic condition is also possible. Low grass production in dry land area is mainly due to the limited availability of soil moisture and plant nutrients. Agrawal et al., (2001) reported NB hybrid is superior to guinea grass or setaria grass. However the economy of production plays an important role in introduction/ adoption of a crop in an area, village or farm. Many earlier studies have been conducted on economics of BN Hybrid production at research farm, or other government farms. But the information on economics of BN hybrid production at farmer’s field and its integration livestock feeding as well rooted slips are limited. Therefore, the present study was conducted with the object to study the economics of BN hybrid at farmer’s field in Bundelkhand

Study of HgOH to Assess Its Suitability for Electron Electric Dipole Moment Searches

In search of suitable molecular candidates for probing the electric dipole moment (EDM) of the electron (de), a property that arises due to parity and time-reversal violating (P,T-odd) interactions, we consider the triatomic mercury hydroxide (HgOH) molecule. The impetus for this proposal is based on previous works on two systems: the recently proposed ytterbium hydroxide (YbOH) experiment [Phys. Rev. Lett. 119, 133002 (2017)] that demonstrates the advantages of polyatomics for such EDM searches, and the finding that mercury halides provide the highest enhancement due to de compared to other diatomic molecules [Phys. Rev. Lett. 114, 183001 (2015)]. We identify the ground state of HgOH as being in a bent geometry, and show that its intrinsic EDM sensitivity is comparable to the corresponding value for YbOH. Along with the theoretical results, we discuss plausible experimental schemes for an EDM measurement in HgOH. Furthermore, we provide pilot calculations of the EDM sensitivity for de for HgCH₃ and HgCF₃, that are natural extensions of HgOH

The electron electric dipole moment enhancement factors of Rubidium and Caesium atoms

The enhancement factors of the electric dipole moment (EDM) of the ground states of two paramagnetic atoms; rubidium (Rb) and caesium (Cs) which are sensitive to the electron EDM are computed using the relativistic coupled-cluster theory and our results are compared with the available calculations and measurements. The possibility of improving the limit for the electron EDM using the results of our present work is pointed out.Comment: AISAMP7 Conference paper, Accepted in Journal of Physics: Conference Series: 200

Relativistic coupled cluster calculations of the energies for rubidium and cesium atoms

Ionization potentials and excitation energies of rubidium and cesium atoms are computed using the relativistic coupled cluster (CC) method. The effect of electron correlations on the ground and excited state properties is investigated using different levels of CC approximations and truncation schemes. The present work demonstrates that the even-parity channel truncation scheme produces results almost as accurate as obtained from the all-parity channel approximation scheme at a reduced computational cost. The present study also indicates that for a given basis the linearized CC method tends to overestimate the ground and excited state properties compared to the full CC method

Constraints for Grassland Development in Kadesara Kala Village, Lalitpur, Bundelkhand: A Case Study

India is maintaining a livestock population of over 500 million and has a grim situation of forage and feed deficit to the tune of 35.6% green fodder, 10.95% crop residues and 44% concentrate. In term of nutrients, the deficit is expected to the tune of 24.6 and 19.9% respectively by the year 2020. The gap is to be bridged up through development as well as extension of appropriate fodder production technologies suitable for different farming situation strategies. Fifty-eight % of the available fodder comes from grazing land and 42% from stall feeding with crop residues (30%) and leaf fodder (12%). Grasses constitute the majority (88%) of fodder available in Uttar Pradesh (GOUP, 1994). However, the role of grasslands cannot be under judged, as the large animal populations owned by small, marginal and landless farm family strive upon these. The livestock sector achieved an average growth rate of 4.8 per cent during the Eleventh Five Year Plan (Economic Survey, 2012-13) and it contributed 3.6 percent of national GDP during the Eleventh Plan. In the same tune, the contribution from this sector is expected to improve because increasing purchasing power is favoring the proportion of protein from animal source in the human diets. Further, The Indian livestock sector is becoming more competitive participant in the world market. All this largely depends, however, on improvement and sufficiency in the production of feeds and forages. Notwithstanding the above, the grasslands and pastureland in the country are continuously shrinking. The paper addresses important issues limiting the development of new grasslands in semiarid Bundelkhand region of Uttar Pradesh particularly the Lalitpur district
