In combating malicious domains, fundamental platforms for a wide range of attacks, domain name service (DNS) data reveal extensive traces of internet activity, acting as a potent resource. This paper proposes a model, enabled by passive DNS data analysis, for the identification of malicious domains. The model under consideration builds a real-time, precise, middleweight, and rapid classifier by merging a genetic algorithm for the selection of DNS data characteristics with a two-phase quantum ant colony optimization (QABC) algorithm for categorization. merit medical endotek The K-means algorithm, in place of random selection, is employed by the revised two-step QABC classifier to position food sources. This paper employs the QABC metaheuristic, drawing inspiration from quantum physics, to address global optimization challenges, thereby overcoming the deficiencies in ABC's exploitation and convergence speed. Biostatistics & Bioinformatics One of the primary contributions of this paper is the application of a hybrid approach, incorporating K-means and QABC techniques, within the Hadoop framework to address the considerable size of uniform resource locator (URL) data. The suggested machine learning methodology may lead to improvements in blacklists, heavyweight classifiers (which require a significant feature count), and lightweight classifiers (requiring less browser-sourced data). The suggested model's effectiveness was corroborated by the results, which showed over 966% accuracy for more than 10 million query-answer pairs.

Liquid crystal elastomers (LCEs), being polymer networks, demonstrate reversible high-speed and large-scale actuation in response to external stimuli, a characteristic arising from their combined elastomeric and anisotropic liquid crystalline properties. A non-toxic, low-temperature liquid crystal (LC) ink was formulated for temperature-controlled direct ink writing 3D printing, in this work. The phase transition temperature of 63°C, as measured by DSC, provided the basis for investigating the rheological characteristics of the LC ink across varied temperature ranges. The actuation strain of printed liquid crystal elastomer (LCE) structures, in response to variations in printing speed, printing temperature, and actuation temperature, was the focus of a study within adjustable parameter settings. The printing direction was shown to be a factor in the diverse actuation behavior of the LCEs, as demonstrated. Ultimately, through the sequential shaping of structures and the programming of printing parameters, the deformation characteristics of a multitude of intricate structures were illustrated. Utilizing 4D printing and digital device architectures, the presented LCEs' unique reversible deformation property makes them ideal for applications like mechanical actuators, smart surfaces, and micro-robots.

Due to their impressive tolerance to damage, biological structures are considered a strong choice for ballistic protection. To investigate the performance of crucial ballistic protection structures, this paper introduces a finite element modeling framework that examines nacre, conch, fish scales, and crustacean exoskeletons. In order to determine the geometric parameters of bio-inspired structures that endure projectile impact, finite element simulations were carried out. The performances of the bio-inspired panels were evaluated by comparing them to a monolithic panel of equal 45 mm overall thickness and encountering the same projectile impact conditions. Studies demonstrated that the biomimetic panels, when examined, displayed stronger multi-hit resistance than the selected monolithic panels. Certain structural configurations stopped a projectile fragment simulation, characterized by an initial velocity of 500 meters per second, displaying a performance consistent with the monolithic panel.

The adverse effects of extended sitting, including awkward positions, often manifest as musculoskeletal disorders. To combat the detrimental effects of prolonged sitting, this study presents a cushion design for chair attachments, incorporating an ideal air-blowing method. The proposed design seeks to achieve an immediate reduction in the contact space between the chair and its user. YUM70 price Integrated FAHP and FTOPSIS fuzzy multi-criteria decision-making methods for evaluating and selecting the best proposed design. Through simulation software (CATIA), a validated ergonomic and biomechanical assessment of the occupant's seating posture was performed, featuring the innovative safety cushion design. The design's strength was corroborated by the use of sensitivity analysis. The chosen evaluation criteria, when applied to the results, pinpointed the manual blowing system using an accordion blower as the most desirable design concept. The design in question indeed produces an appropriate RULA index for the evaluated sitting positions, and it was demonstrably safe in the single-action biomechanical assessment.

In the context of hemostatic agents, gelatin sponges are prominently featured, and their potential as three-dimensional scaffolds for tissue engineering is drawing considerable attention. To expand their potential uses in tissue engineering, a simple synthetic procedure was established to securely attach the disaccharides maltose and lactose for targeted cell adhesion. Using 1H-NMR and FT-IR spectroscopy, a high conjugation yield was confirmed, while the morphology of the decorated sponges was characterized using SEM. Following the crosslinking process, the sponges maintain their porous architecture, as confirmed by scanning electron microscopy. Ultimately, high cell viability and substantial differences in cellular morphology are observed in HepG2 cells that are cultured on gelatin sponges modified by the addition of conjugated disaccharides. On maltose-conjugated gelatin sponges, a spherical morphology is more frequently observed, whereas a flatter shape emerges when cultured onto lactose-conjugated gelatin sponges. Due to the expanding interest in the use of small carbohydrates as signaling elements on biomaterial surfaces, a structured approach to understanding how these small carbohydrates affect cell adhesion and differentiation processes could benefit from the methodology described.

Mimicking the sophisticated auditory sense of sand cats, the Sand Cat Swarm Optimization (SCSO) algorithm offers a powerful and straightforward metaheuristic approach, producing excellent performance in solving large-scale optimization challenges. The SCSO, in spite of its strengths, continues to face disadvantages, including slow convergence, lower precision in convergence, and the tendency for getting caught in local optima. This research introduces a novel adaptive sand cat swarm optimization algorithm, COSCSO, which utilizes Cauchy mutation and an optimal neighborhood disturbance strategy, thereby avoiding the mentioned drawbacks. Foremost among the benefits is the introduction of a non-linear, adaptive parameter which aids in the expansion of the global search space, helping in the location of the global optimum and avoiding the trap of a local optimum. Furthermore, the Cauchy mutation operator disrupts the search trajectory, thereby augmenting the convergence rate and enhancing the search effectiveness. The best strategy for neighborhood disruptions within an optimization framework aims to diversify the population, broaden the search space, and improve the exploitation of discovered solutions. In order to gauge COSCSO's performance, it was compared against alternative algorithms in the CEC2017 and CEC2020 competition suites. The COSCSO method is further deployed in order to solve six significant engineering optimization problems. Empirical evidence suggests the COSCSO possesses robust competitiveness and deployability for practical problem-solving.

A substantial 839% of breastfeeding mothers in the United States, as indicated by the 2018 National Immunization Survey conducted by the Center for Disease Control and Prevention (CDC), have had experience with a breast pump. Yet, the overwhelming number of current products depend on a vacuum-based mechanism exclusively for milk removal. The act of expressing milk frequently leads to prevalent breast injuries like tenderness in the nipples, damage to the breast's structure, and complications in the production and flow of breast milk. Developing a bio-inspired breast pump prototype, SmartLac8, replicating infant suckling patterns was the focus of this research. The input vacuum pressure pattern and compression forces are modeled on the natural oral suckling dynamics of term infants, as documented in previous clinical trials. For the purpose of designing controllers ensuring closed-loop stability and control, the use of open-loop input-output data facilitates system identification of two distinct pumping stages. A physical breast pump prototype, utilizing soft pneumatic actuators and custom piezoelectric sensors, was successfully developed, calibrated, and put through rigorous testing in controlled dry lab environments. Expertly synchronized compression and vacuum pressure dynamics successfully replicated the infant's natural feeding process. Clinical findings matched the experimental observations of sucking frequency and pressure on the breast phantom.
