Abstract

Background: Narcotics-related crimes continue to be a significant issue worldwide, with prison sentences often viewed as a primary deterrent. However, there is limited empirical evidence regarding the effectiveness of incarceration in reducing the incidence of narcotics crimes. The question remains whether prison sentences lead to long-term reductions in drug-related offenses or merely function as a short-term punitive measure without addressing underlying issues such as addiction and socio-economic factors. Objective: This study aims to evaluate the effectiveness of prison sentences in preventing narcotics crimes, focusing on recidivism rates and rehabilitation outcomes for offenders. The research investigates whether incarceration contributes to long-term crime prevention or if alternative approaches, such as rehabilitation programs, offer more sustainable results. Method: A mixed-methods approach was employed, combining quantitative data analysis of recidivism rates from convicted drug offenders and qualitative interviews with legal professionals, offenders, and rehabilitation experts. The data collected spans a five-year period and includes case studies from various correctional facilities. Results: The findings indicate that while prison sentences temporarily reduce narcotics crime, they are less effective in preventing recidivism. Rehabilitation programs integrated into the prison system significantly contributed to reducing reoffending rates, particularly when combined with post-release support. Conclusion: Prison sentences alone are insufficient in preventing narcotics crimes. A more comprehensive approach, including rehabilitation and social reintegration efforts, is necessary for long-term success in reducing narcotics-related offenses.

Abstract

Physical qubits intuitively introduces greater cumulative noise and control complexity. This “Qubit Paradox” presents a fundamental barrier to scalability, suggesting that larger systems might become inherently less stable. This research aims to rigorously validate the threshold theorem, defining the precise boundary where topological protection overcomes physical noise accumulation. We utilized high-fidelity Monte Carlo simulations of Rotated Surface Codes, scaling from distance d=3 to d=9, under realistic circuit-level noise models including leakage and crosstalk. Decoding was executed using the Minimum Weight Perfect Matching (MWPM) algorithm to analyze logical failure rates across 109 error correction cycles. Results identify a critical physical error threshold of approximately 0.57%. Below this value, logical error rates exhibited exponential suppression via power-law decay, reducing by seven orders of magnitude at distance-9. Conversely, systems operating above this threshold demonstrated error amplification with increased scale. We conclude that the paradox resolves only when individual gate fidelity surpasses the threshold, mandating that hardware optimization must precede quantitative scaling. These findings establish a validated roadmap for the transition from the NISQ era to fault-tolerant architecture.

The rapid expansion of smart farming systems has intensified the need for reliable wireless communication infrastructures capable of supporting Internet of Things (IoT) applications in heterogeneous agricultural environments. Ensuring stable connectivity in rural areas characterized by large coverage demands, energy constraints, and environmental interference remains a critical challenge. This study aims to evaluate wireless communication technologies and identify optimal configurations that enable reliable IoT-based smart farming operations. A mixed-method research design integrating large-scale field experiments and simulation-based scalability analysis was employed to assess LoRaWAN, NB-IoT, Zigbee, Wi-Fi, and 5G IoT modules. Reliability was measured using packet delivery ratio, latency, coverage range, scalability, and energy consumption indicators. Results indicate that no single technology achieves optimal performance across all reliability dimensions. LPWAN technologies demonstrated superior energy efficiency and wide-area coverage, while 5G achieved the lowest latency and highest throughput. Hybrid communication architectures consistently outperformed single-technology deployments, improving packet delivery ratio and operational resilience under varying environmental conditions.
