The solution to evolution equations has developed an independent theory within nonlinear analysis dealing with the existence and approximation of such solution （ fixed point） of pseudocontractive operators and its variants. The ob.ect is to introduce a perturb.d iteration method for proving the convergence of sequence of Lipschitzian pseudocontractive mapping using approximate fixed point technique. This iteration can b. ued for nonlinear operators which are more general than Lipschitzian pseudocontractive operator and b.uck.iteration fails for proving their convergence. Our results generalize the results of Chidume and Zegeye.

Network.attack.detection and mitigation require pack.t collection， pre-processing， feature analysis， classification， and post-processing. Models for these task. sometimes b.come complex or inefficient when applied to real-time data samples. To mitigate hyb.id assaults， this study designs an efficient forensic layer employing deep learning pattern analysis and multidomain feature extraction. In this paper， we provide a novel multidomain feature extraction method using Fourier， Z， Laplace， Discrete Cosine Transform (DCT)， 1D Haar Wavelet， Gab.r， and Convolutional Operations. Evolutionary method dragon fly optimisation reduces feature dimensionality and improves feature selection accuracy. The selected features are fed into VGGNet and GoogLeNet models using b.nary cascaded neural network. to analyse network.traffic patterns， detect anomalies， and warn network.administrators. The suggested model tack.es the inadequacies of existing approaches to hyb.id threats， which are growing more common and challenge conventional security measures. Our model integrates multidomain feature extraction， deep learning pattern analysis， and the forensic layer to improve intrusion detection and prevention systems. In diverse attack.scenarios， our technique has 3.5% higher accuracy， 4.3% higher precision， 8.5% higher recall， and 2.9% lower delay than previous models.

The humid agroclimatic conditions of k.rala,India permit the cultivation of an array of b.mb.o species of which Dendrocalamus strictus Roxb.(Nees.) is an important one on account of its high growth rate and multiple uses. Stand density, a potential tool in controlling the productivity of woody ecosystems, its effect on growth and root distrib.tion patterns may provide a b.tter understanding of productivity optimization especially when b.mb.o-b.sed intercropping options are *** attrib.tes of 7-year-old b.mb.o(D. strictus) stands managed at variab.e spacing(4×4 m, 6×6 m, 8×8 m,10×10 m, 12×12 m) were studied. Functional root activity among b.mb.o clumps were also studied using a radio tracer soil injection method in which the radio isotopeP was applied to soil at varying depths and lateral distances from the clump. Results indicate that spacing exerts a profound influence on growth of b.mb.o. Widely spaced b.mb.o exhib.ted higher clump diameters and crown widths while clump heights were b.tter under closer spacing. Clump height was 30% lower and Db. 52%higher at the widest spacing(12×12 m) compared to the closest spacing(4×4 m). With increasing soil depth and lateral distance, root activity decreased significantly. Root activity near the clump b.se was highest(809 counts per minute, cpm; 50 cm depth and 50 cm lateral distance) at 4×4 m. Tracer study further showed wider distrib.tion of root activity with increase in clump spacing. It may b. concluded that the intensive foraging zone of b.mb.o is within a 50-cm radius around the clump irrespective of spacing. N, P and k.content in the upper 20 cm was 2197,21, and 203 k./ha respectively for the closely spaced b.mb.o(4×4 m) which were significantly higher than corresponding nutrient content at wider spacings. Ab.ut 50% of N, P and k.were present within the 0–20 cm soil layer, which decreased drastically b.yond the 20 cm *** results suggest that stand management practices through planting density regula
