    Abstract Cloud computing security has been a critical issue with its increase in demand. One of the most challenging problems in cloud computing is detecting distributed denial-of-service (DDoS) attacks. The attack detection framework for the DDoS attack is tricky because of its nonlinear nature of interruption activities, atypical system traffic behaviour, and many features in the problem space. As a result, creating defensive solutions against these attacks is critical for mainstream cloud computing adoption. In this novel research, by using performance parameters, perplexed-based classifiers with and without feature selection will be compared with the existing machine learning algorithms such as naïve Bayes and random forest to prove the efficacy of the perplexed-based classification algorithm. Comparing the performance parameters like accuracy, sensitivity, and specificity, the proposed algorithm has an accuracy of 99%, which is higher than the existing algorithms, proving that the proposed algorithm is highly efficient in detecting the DDoS attacks in cloud computing systems. To extend our research in the area of nature-inspired computing, we compared our perplexed Bayes classifier feature selection with nature-inspired feature selection like genetic algorithm (GA) and particle swarm optimization (PSO) and found that our classifier is highly efficient in comparison with GA and PSO and their accuracies are 2% and 8%, respectively, less than those of perplexed Bayes classifier.

    Abstract Research experiments were carried out with six promising potato clones of International Potato Center (CIP) compared with four recommended varieties of Central Potato Research Institute (CPRI) as checks with the objective to identify high yielding, short duration variety suitable for rice-wheat cropping system of subtropical region of Haryana. The trials were conducted at Potato Technology Center, Karnal during rabi season of two consecutive years, viz. 2018–19 and 2019–20 under Rastriya Krishi Vikas Yojna Project. The experiments were laid out in randomized block design with three replications. All the cultural practices were followed with scientific management. Dehaulming was done after 75 days of planting. Physical characters of tubers like skin colour, flesh colour, tuber shape and eye depth were observed. Data related to vegetative growth and yield was recorded, pooled and statistically analyzed. It was observed from the data that the maximum plant vigour was recorded in cultivar Kufri Lima however, highest marketable and total tuber yield was recorded in a red skinned CIP clone CIP392797.22. This variety might be selected as a candidate variety fit for rice-wheat cropping system.

    Abstract Thermodynamic and surface properties of the ternary system were studied at different higher temperatures (1973 K, 2073 K, 2173 K and 2273 K). The thermodynamic properties were studied using the Chou, Kohler and Toop models. Meanwhile, the surface properties were investigated using the same models plus the Butler model. The thermodynamic and surface properties of the ternary alloys computed from different models were compared with one another. The surface concentration of the components of the ternary Ti–Al–Si alloy was computed using Butler's equation.

    Abstract Oral cancers are one of the most common cancers affecting people of Nepal and it the sixth most common cancer in the world. Unlike other cancers the early detection of the disease is possible through a routine examination of the oral cavity which is usually done by a dental practitioner. Through a series of phases like prevention, screening, early intervention, diagnosis and staging, management with tumor ablative surgeries, and rehabilitation to restore the function and esthetic part for better clinical outcome, the role of the specialty of dentistry is immensified. From a patient perspective, having a direct referral line within the dental community between dentists and oral and maxillofacial surgeons will contribute to cost reduction and improvement in outcomes. Trained oral and maxillofacial surgeon especially in the head and neck oncology plays a vital role in exploring functional multidisciplinary efforts to enhance patient care, academic excellence and research initiatives and evaluate for gaps in patient care. This article highlights the role of such professionals in a multidisciplinary team approach for the proper management of head and neck cancers which have significantly and logically additive effect for a better outcome. Keywords: Oral cancer; oral cancer surgery; oral and maxillofacial surgery; multidisciplinary treatment oral cancer; head and neck cancer surgery.

    Abstract Temperature-dependent interaction parameters of Redlich-Kister (R–K) polynomials for Li–Mg alloy in liquid phase have been optimized using experimental data in the framework of linear and exponential models. These parameters have then been used to compute the thermodynamic properties (excess Gibbs free energy of mixing, enthalpy of mixing and activity) and structural property (concentration fluctuations in the long-wavelength limit) of the alloy at temperatures 1000 K, 1300 K, 1600 K, 1900 K, and 2200 K. The negative values of excess Gibbs free energy of mixing computed using linear T-dependent parameters increases with the rise in the temperature of the system beyond 1000 K while the same physical quantity computed using the exponential T-dependent interaction parameters decreases with the rise in temperatures and does not show any unusual trends up to 2200 K. Similar behavior has been found in the case of other thermodynamic and structural functions. The unusual behavior that appears in the thermodynamic and structural functions computed using linear T-dependent parameters can be eliminated if these functions are computed using exponential T-dependent parameters.

    Abstract Area under organic cultivation of wheat (Triticum aestivum L.) is increasing in India. The present two-year study was carried out during 2017–18 and 2018–19 to observe the yield performance of wheat with application of silicon solution (amorphous silica SiO2) under sub-humid conditions of southern plains and Aravalli Hills of Rajasthan. Factorial RBD with five levels of silicon concentration and three growth stages, viz. CRI, tillering and jointing stages were replicated thrice during rabi season of 2017–18 and 2018–19 at Udaipur, Rajasthan, India. Results revealed that application of silicon 8 g/litre water at tillering stage proved significantly superior in enhancing growth characteristics, yield attributes, yield and also gave maximum net returns of 110281/ha and B:C ratio of 2.32

    Abstract Area under organic cultivation of wheat is increasing in India. Information on the yield performance and economic suitability of wheat varieties for organic farming in different agro climatic conditions is lacking. The present two year study was carried out during 2015 and 2016 to observe the yield performance of different varieties of bread, durum and local wheat under sub-humid conditions of southern plains and Aravalli Hills of Rajasthan. Results revealed that among the 12 varieties of wheat tested under organic production system, the maximum grain yield (56.39 q/ha) was obtained from durum wheat variety HI-8713 having 53.50 grains/ear followed by bread wheat variety MP-3288 (45.74 q/ha grain yield) bearing 51.67 grains/ear during both the years. Under organic production system the durum wheat variety HI-8713 recorded maximum net profit of ₹ 170700/ha which was higher by ₹ 68247, ₹ 79436 and ₹ 85055 over the commonly grown wheat varieties Raj-4037, Raj-3765 and Raj-4120, respectively.

    Abstract Climate change is now unequivocal and influences crops and the incidence of insect pests. Understanding the spatially variable, species-specific, and complex effects of climate change is essential in developing an appropriate pest management strategy. The two dimensions of climate change i.e., elevated temperature ( e Temp.) and elevated CO _2 ( e CO _2 ) influence insect herbivores. In the present study, the growth and development of an invasive insect pest, fall armyworm, Spodoptera frugiperda (J E Smith) (Lepidoptera: Noctuidae) on maize at e CO _2 and e Temp conditions using CO _2 and temperature Gradient Chambers (CTGC) was estimated. Dilution of bio-chemical constituents was noted with lower leaf nitrogen (9%–14%), higher carbon (3%–11%), higher C : N (18%–26%), and higher tannins (13%) in maize foliage at e CO _2 + e Temp levels. A significant influence on primary parameters of insect viz., higher total consumption by larvae (38%), extended larval duration (13%) with increased larval weights (17%), and differential pupal weights (14%) in successive generations was recorded at e CO _2 + e Temp compared to ambient. Their effect was continued on various insect performance indices also, with higher relative consumption rate, RCR (40%), lower relative growth rate, RGR (11%), and varied approximate digestibility (AD), the efficiency of conversion of ingested food (ECI) and digested food (ECD) of S frugiperda larvae. The interactive effect of e CO _2 and e Temp led to a higher Potential Population Increase Index (PPII) (19%) due to higher fecund adults. The effect of e CO _2 offsets the impact of e Temp when interacting together on some of the insect parameters. The present results indicate that e CO _2 and e Temp play a key role in influencing the growth and development of S frugiperda indicating higher pest incidence in future climate change periods.
