Nonommutative Wormholes in f(R) Gravity
Mubasher Jamil,Farook Rahaman,Ratbay Myrzakulov,Peter Kuhfittig,Nasr Ahmed,Umar Mondal 한국물리학회 2014 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.65 No.6
This paper discusses several new exact solutions for static wormholes in f(R) gravity with anoncommutative-geometry background. In the first part of the paper, we assume the power-lawform f(R) = aRn and discuss several solutions corresponding to different values of the exponent. The second part of the paper assumes a particular form of the shape function that also yields aviable solution. This investigation generalizes some of our previous work in f(R) gravity, as well asin noncommutative geometry.

With the improvement of economic status and the desire for beauty, the interest in health and skin care is increasing. For these demands, since ages medicinal plants are in vogue. A variety of plants, cosmetics and foods with novel bioactive ingredients for skin care and beauty are under constant research and development. Skin is influenced by various factors such as Ultra-violet rays, stress, hormones and aging which together lead skin to lose elasticity, changes in pigmentation and wrinkle formation. Many medicinal plants have proven effects in skin care and beauty treatment. From this list of medicinal plants, one which is famous for its beauty, flavor and fragrance is Rosa damascene. Rosa damascene has many therapeutic action and postulated pharmacological studies such as anti-arthritic, anti-microbial, cardio protective, anti-inflammatory, antioxidant, analgesic, immune-modulator, gastro-protective, and skin ameliorative effect. Research in the field of Cosmetology has proven the effect of Rosa damascene in rehydrating skin, reducing scars and stretches, acne management, lowering skin pigmentation, delaying wrinkling and is recommended as a skin vitalizing agent. In this review, the morphology, chemical constituents, and some pharmacological activity are discussed.

Multivariate energy harvesting system, solar and thermalenergies, with configurable impedance matching features ispresented. The system consists of a tuneable mechanism forpeak performance tracking. The inputs are voltages rangingfrom 20 mV to 3.1 V. The matching load is individually tunedfor photovoltaic and thermoelectric power efficiency not lessthan 80% and 50% of the open circuit voltage respectively. Ofexperimentation and analysis has been done, the time it takesto fully charge up to 3.4 V is 23 minutes with the rate ofcharging is 1.8 mV/sec. Empirical data is presented.

Fog computing aims to provide the solution of bandwidth, network latency and energy consumption problems of cloud computing. Likewise, management of data generated by healthcare IoT devices is one of the significant applications of fog computing. Huge amount of data is being generated by healthcare IoT devices and such types of data is required to be managed efficiently, with low latency, without failure, and with minimum energy consumption and low cost. Failures of task or node can cause more latency, maximum energy consumption and high cost. Thus, a failure free, cost efficient, and energy aware management and scheduling scheme for data generated by healthcare IoT devices not only improves the performance of the system but also saves the precious lives of patients because of due to minimum latency and provision of fault tolerance. Therefore, to address all such challenges with regard to data management and fault tolerance, we have presented a Fault Tolerant Data management (FTDM) scheme for healthcare IoT in fog computing. In FTDM, the data generated by healthcare IoT devices is efficiently organized and managed through well-defined components and steps. A two way fault-tolerant mechanism i.e., task-based fault-tolerance and node-based fault-tolerance, is provided in FTDM through which failure of tasks and nodes are managed. The paper considers energy consumption, execution cost, network usage, latency, and execution time as performance evaluation parameters. The simulation results show significantly improvements which are performed using iFogSim. Further, the simulation results show that the proposed FTDM strategy reduces energy consumption 3.97%, execution cost 5.09%, network usage 25.88%, latency 44.15% and execution time 48.89% as compared with existing Greedy Knapsack Scheduling (GKS) strategy. Moreover, it is worthwhile to mention that sometimes the patients are required to be treated remotely due to non-availability of facilities or due to some infectious diseases such as COVID-19. Thus, in such circumstances, the proposed strategy is significantly efficient.
