Femtocells, which are widely deployed within a macrocell, are considered to be a novel technology that leads to the escalation of indoor coverage and capacity. However, due to lack of coordination between the femtocell and the macrocell, designing a distributive resource and power allocation is a challenging task. In this study, a potential game (PG)-theoretic approach is proposed for joint resource and power allocation (JRPA), which is demonstrated to exhibit unique Nash Equilibrium. Specifically, femto-base stations, which are considered as the players of the PG, learn the strategies in terms of resource and power allocation by taking into account the interest of other entities. To this end, the utility function of players is designed such that it minimizes the impact interference and the satisfaction for improving the femtocell capacity, without jeopardizing the macrocell performance. Precisely, the utility function incorporates all the sources of interference such as co-tier and cross-tier, and also the reward of each player in terms of capacity. The proposed PG-based JRPA is solved by employing the better response dynamics, which selects the resources and the power levels by utilizing a particle swarm optimization-constriction factor model. The performance of PG-based JRPA is analyzed in regard to average femtocell capacity and system capacity. Additionally, two different traffic cases are considered: high load traffic and low load traffic. For the sake of comparison, random allocation is employed. Simulation results are carried out in terms of the performance metrics, which includes convergence, min-max capacity, varying resource blocks, femtocell density and fairness. The results illustrate the superior performance of the proposed PG in terms of the aforementioned performance metrics.

The constitutive and induced resistance were studied in two varieties (Khanyari and Kawdari) of kale, Brassicaoleracea var. acephala in response to cabbage butterfly, Pieris brassicae infestation and exogenous application ofjasmonic acid (JA) and salicylic acid (SA). Phenols, condensed tannins, flavonoids and proteins were measuredat six days after JA (1 mM) and SA (1 mM) application and/or insect infestation. Plant damage and larvalweights were also recorded. Khanyari variety showed highest amounts of phenols (208.23 μg/g FW), condensedtannin (347.76 μg/g FW), flavonoids (175.61 μg/g FW) and proteins (0.71 mg/g FW) in plants pre-treated withJA and infested with insects. The PAL activity was high in response to JA application followed by insect infestation. Insects reared on Khanyari and Kawdari plants pre-treated with JA prior showed significantly reducedlarval weights (97.88 and 102.46 mg, respectively). Damage was low in plants pre-treated with JA in Khanyari at3, 6 and 9 days after treatment (10.52%, 8.52%, and 5.30%, respectively). Thus, JA can play an important role inplant defense in kale against P. brassicae.

To compare the efficacy of two Unani regimen in diabetic vulovaginal candidiasis (VVC). A prospective, randomized, single-blind, comparative trial was conducted at Nizamia Tibbia College. Group A (n = 23) medicine included 100 ml of Joshanda [Ushba Desi (5 g) and Tukhme Hayat (5 g)] with 3 g Sufuf [Mur Makki (1 g), Afsanteen (2 g), and Nagandbabari (3 g)] orally twice daily half an hour before meal. Locally, douche (Aab Barg Bakayan (5 g) and Sufuf Katha (1 g) followed by humul [Roghan Neem (10 ml), Luab Gheegawar (2 g) and Sufuf Zard Chobb (1 g)] was given daily once. Group B (n = 23) received 100 ml of aforementioned Joshanda with 3 g sufuf [Kutki Siyaha (2 g), Kali Zeeri (2 g) and Tukhme Kasni (2 g)] orally twice daily half an hour before meal. Locally, douche (Gulanar (5 g) and Barg babool 5 (g)] was given daily once. Both groups received the treatment for 10 days for three consecutive months. The primary outcomes included change in vaginal discharge and wet mount test. The secondary outcomes included other clinical features of VVC and blood glucose level. The results were analyzed. Group A and B showed absence of vaginal discharge and fungal spores/hyphae in 91.30% and 86.95% respectively, statistically not significant (P = 0.3), whereas pre- and post-test comparison was statistically significant in both groups (P < 0.001). Inter-group comparison was statistically non significant (P > 0.05) for remission of other clinical features and blood glucose level, whereas pre- and post-test comparison showed statistically significant difference in both groups (P < 0.001). Both groups were equally effective for the treatment of diabetic VVC.
Dynamic Fractional Frequency Reuse based on an Improved Water-Filling for Network MIMO

In Long Term Evolution-Advanced (LTE-A) systems, Inter-cell Interference (ICI) is a prominent limiting factor that affects the performance of the systems, especially at the cell edges. Based on the literature, Fractional Frequency Reuse (FFR) methods are known as efficient interference management techniques. In this report, the proposed Dynamic Fractional Frequency Reuse (DFFR) technique improved the capacity and cell edge coverage performance by 70% compared to the Fractional Frequency Reuse (FFR) technique. In this study, an improved power allocation method was adopted into the DFFR technique to reach the goal of not only reducing the ICI mitigation at the cell edges, but also improving the overall capacity of the LTE-A systems. Hence, an improved water-filling algorithm was proposed, and its performance was compared with that of other methods that were considered. Through the simulation results and comparisons with other frequency reuse techniques, it was shown that the proposed method significantly improved the performance of the cell edge throughput by 42%, the capacity by 75%, and the coverage by 80%. Based on the analysis and numerical expressions, it was concluded that the proposed DFFR method provides significant performance improvements, especially for cell edge users.

The interest in use of insects for human food has also resulted in the appearance of insect-based dog and cat food products in the market. Insect-based pet food producers are using several health and sustainability claims for marketing purposes, which are expected to be the main drivers of market growth in the near future. In this paper, we systematically synthesize information about the insect-based pet food market, investigating the type of products commercially available, providing a geographical overview and type of insect species being commonly used in these products. We then try to synthesize information about health and sustainability claims currently being used by insect-based pet food companies in different geographies. Finally, we review information about consumer perception of: (1). these products in general; and (2). claims being used to market these products. The insect-based pet food market is growing rapidly in Europe. Recent regulatory approval in the USA will push this growth in the North American market too. It appears that consumers have connected very well with sustainability, hypoallergenicity and the overall gut health claims. Finally, insect-based pet food producers should: (1). adopt systematic marketing; (2). produce more scientific evidence; and (3). actively communicate and partner with veterinarians to improve the consumer perception of claims used on insect-based pet foods.

Medicinal use of plants is as old as human history. Curcuma longa, Nigella sativa seeds, and Camellia sinensis have been widely used in various remedies since ages. In this study, the effect of extraction method on different bioactivities and phytochemical constituents of Curcuma longa, Nigella sativa seeds, and Camellia sinensis were evaluated and compared using single solvent system (50% ethanol). Plant extracts were prepared by percolation-assisted extraction, sonication-assisted extraction, microwave-assisted extraction, and polyphenol extraction. Following phytochemical screening, extracts were screened for antioxidant activity, antihemolytic activity, osmotic tolerance, and osmotic fragility. All plant extracts showed good phytochemical content irrespective of extraction method. However, activities in vitro antioxidant assays were dependent on plant as well as on extraction methods. Promising results were observed for antihemolytic activity against hydrogen peroxidetreated erythrocytes. Overall, Camellia sinensis exhibited the highest bioactivities followed by Curcuma longa and Nigella sativa seeds.
