To combat malicious domains, which serve as a key platform for a wide range of attacks, domain name service (DNS) data provide rich traces of Internet activities and are a powerful resource. This paper presents new research that proposes a model for finding malicious domains by passively analyzing DNS data. The proposed model builds a real-time, accurate, middleweight, and fast classifier by combining a genetic algorithm for selecting DNS data features with a two-step quantum ant colony optimization (QABC) algorithm for classification. The modified two-step QABC classifier uses -means instead of random initialization to place food sources. In order to overcome ABCs poor exploitation abilities and its convergence speed, this paper utilizes the metaheuristic QABC algorithm for global optimization problems inspired by quantum physics concepts. The use of the Hadoop framework and a hybrid machine learning approach (K-mean and QABC) to deal with the large size of uniform resource locator (URL) data is one of the main contributions of this paper. The major point is that blacklists, heavyweight classifiers (those that use more features), and lightweight classifiers (those that use fewer features and consume the features from the browser) may all be improved with the use of the suggested machine learning method. The results showed that the suggested model could work with more than 96.6% accuracy for more than 10 million query-answer pairs.

Since the publication of the 2021 FIGO Cancer Report, there has been further progress in the global effort to attain the WHO goal of cervical cancer elimination using a three-pillar approach of vaccination, screening, and treatment. The HPV vaccination is now included in the national program of over 140 countries. Two-dose schedules are being implemented in 80 countries and one-dose schedules in 60 countries.

Background: Early psychosis (EP) is associated with a disrupted integrity of the white matter microstructure of a variety of brain regions, especially the corpus callosum (CC). In this study, we used diffusion-weighted magnetic resonance imaging data of patients with EP and employed diffusion tensor imaging (DTI), free water-corrected diffusion, and neurite orientation dispersion and density imaging (NODDI) to comprehensively assess the white matter microstructure.
Methods: 106 patients with EP (84 non-affective and 22 affective) and 51 healthy controls (HCs) were included from the Human Connectome Project in the Early Psychosis dataset.

A scaling relation has been derived to link the fractal dimension of a flame surface with the ratio of the normalised 3D flame surface area to its 2D counterpart. This derivation assumes an isotropic distribution of angles between the measurement plane and the flame's normal vector, as well as a uniform distribution of angles between the principal direction and the flame's tangent vector. The validity of the newly derived relation was assessed using an existing Direct Numerical Simulation (DNS) database of statistically planar turbulent premixed flames, encompassing a range of different Karlovitz numbers.

Domoic acid (DA) is a potent neurotoxin that poses public health concerns, especially for children and adolescents during critical neurodevelopmental periods. In the present study, urinary DA concentrations in 216 children and adolescents at the age of 6 to 18 in southern China were determined using a novel dansyl-chloride (DNS-Cl) derivatization high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) method with ultrahigh sensitivity (LOQ: 0.087 ng/mL).

SEs preferentially form multiway chromatin interactions with other SEs and highly transcribed regions in embryonic stem cells. However, the properties of the interacting SEs and their specific contributions to complex regulatory interactions in differentiated cell types remain poorly understood.
