Amidst the rapidly evolving landscape of B5G/6G wireless networks, the emergence of index modulation has marked a significant development, and one key technique gaining ground is orthogonal frequency division multiplexing-index modulation (OFDM-IM), which boosts both communication and signal transmission spectral efficiency. Although OFDM-IM is an innovative multicarrier modulation technique that builds on the conventional OFDM system. It still confronts a significant challenge related to the High Power Amplifier (HPA) cost, which arises from the distortion that OFDM-IM signals cause when passing through nonlinear devices. this distortion is driven by the considerable Peak-to-Average Power Ratio (PAPR) that characterizes the OFDM-IM signal. In this paper, we propose a novel waveform named Double WHT-OFDM-IM, which combines Double Walsh-Hadamard Transform (WHT) with orthogonal frequency division multiplexing-index modulation (OFDM-IM) to improve the system performance and combat the enormous PAPR of WHT-OFDM-IM in the low number of activated subcarriers scenarios. the proposed approach satisfies the demanding criteria of 6th-generation (6G) and beyond communication schemes, specifically with regard to low peak-to-average power ratio (PAPR), and low bit-error rate (BER).

the resource-constrained IPV6-based low power and lossy network (6LowPAN) is connected through the routing protocol for low power and lossy networks (RPL). this protocol is subject to a routing protocol attack called a rank attack (RA). this paper presents a performance evaluation where leveraging model-free reinforcement-learning (RL) algorithms helps the software-defined network (SDN) controller achieve a cost-efficient solution to prevent the harmful effects of RA. Experimental results demonstrate that the state action reward state action (SARSA) algorithm is more effective than the Q-learning (QL) algorithm, facilitating the implementation of intrusion prevention systems (IPSs) in software-defined 6LowPANs.

international Roughness Index (IRI) stands as a well-established metric for assessing pavement roughness and overall condition. Predicting IRI is crucial for maintaining pavement infrastructure. In this study, we present a novel approach to predict IRI using Random Forest regression, focusing exclusively on traffic characteristics as predictive variables. Existing studies considered a wide range of factors, including pavement materials, climate, structural attributes, and various pavement distress indicators alongside traffic data where we developed our model using only traffic characteristics. We have used Long-Term Pavement Performance Program (LTPP) dataset for training our models. We have compared our Random forest model withthree other models (XGBoost, SVM regression, Gradient Boosting). R squared value and Mean Squared Error (MSE) were taken as performance evaluation metrics. Random forest showed R squared value of 0.70623 and MSE of 8.22 x 10-6 where Gradient Boosting, XGBoost and SVM had R squared value of 0.5737, 0.497, and 0.3455 *** also compared between two hyperparameter tuning methods(Random Search and Grid Search) used in our models and found Random search to perform better. We have also presented a comparative analysis of existing IRI prediction models with our model. Finally we present a SHAP(SHapley Additive exPlanations) analysis to interpret our model and find the contribution of each input feature on our model. We found Annual ESAL (Equivalent Single Axle Load) to be the most dominant factor to predict IRI from traffic characteristics.

We consider the problem of computing gate-circuit approximations of quantum algorithms, i.e., unitary operators, from the perspective of computable (effective) analysis. the scientific community thinks the Solovay-Kitaev theorem a milestone in quantum compiling - the task of computing gate-circuit approximations - because it proves the existence of efficient quantum compilers in an analytic sense. However, since we cannot represent unitary operators in a mere analytical way on digital computers, contemporary digital implementations of quantum compiling resort to heuristic numerics and remain below the computational performance engineers hope to realize using the result of Solovay and Kitaev. this paper discusses quantum compiling within a framework of computable analysis, establishing a concept of computable unitary operators for digital computing based on the theory of Turing machines. Particularly, we prove that digital quantum compiling is uncomputable due to the underlying algebraic structure. Finally, we discuss several implications of our findings for heuristic digital implementations of quantum compiling, hinting toward possible research directions to thoroughly understand the relevant bottlenecks.
