The B3LYP/6–311++G (d, p) computations were used to optimize the structure of the molecule. To provide complete vibrational spectral assignments, vibration energy distribution analysis (VEDA) was used. The Natural bond orbital (NBO) analysis explains the stability and distinct forms of hydrogen bonds with in the molecule. The chemical stability of the molecule is predicted by Highest Occupied Molecular Orbital (HOMO) and Lowest Unoccupied Molecular Orbital (LUMO) analysis. Non-Covalent Interaction (NCI) analysis was done to identify weak interactions according to density of electron of the title compound. The fukui function identified the chemical reactivity sites. To predict its antioxidant efficacy, docking studies were done.

2-(allylthio)-5-(5-phenyl-1H-pyrazol-3-yl)-1,3,4-oxadiazole: Synthesis, single crystal XRD, spectroscopic characterization, antidiabetic activity, DFT and ADMET studies

Here, we synthesized a new potent antidiabetic agent of pyrazolyl-1,3,4-oxadiazole derivative, named 2-(allylthio)-5-(5-phenyl-1H-pyrazol-3-yl)-1,3,4-oxadiazole (ATPO) and characterized it by FT-IR, UV–vis, 1H NMR, 13C NMR, HRMS-ESI, X-ray crystal structure and evaluated as dual inhibitor for α-amylase and α-glucosidase enzymes. Predicted FT-IR, UV–vis, 1H NMR, 13C NMR and UV–vis spectra and geometrical parameters for the optimized structures of ATPO in gas phase and ethanol solution by using B3LYP/6–311++G(d,p) method evidenced very good concordances with the corresponding experimental ones. Studies on atomic charges, molecular electrostatic potentials, stabilization energies and topological properties show that the phenyl, pyrazole and oxadiazole rings together with the allyl thiol moiety play a very important role in the stability, reactivity and behaviours of ATPO in both media. Thus, the compound is less stable in solution probably due to its higher reactivity in this medium and to its solvation energy (-75.89 kJ/mol). Complete vibrational assignments and the scaled force constants were performed for ATPO in both media. Also, ATPO exhibited outstanding α-glucosidase as well as α-amylase inhibitory potential with IC50 values of 35.47 ± 0.42 and 68.99 ± 1.08 µM, respectively, as compared to reference drug acarbose (IC50 (α-glucosidase) = 72.58 ± 0.68 µM, IC50 (α-amylase) = 115.6 ± 0.59 µM). In addition, ADMET studies were performed to investigate the possibility of using of the title compound as antidiabetic drug.

Dual-Loop Control of Cable-Driven Snake-like Robots

Snake-like robots, which have high degrees of freedom and flexibility, can effectively perform an obstacle avoidance motion in a narrow and unstructured space to complete assignments efficiently. However, accurate closed-loop control is difficult to achieve. On the one hand, this is because adding too many sensors to the robot will significantly increase its mass, size, and cost. On the other hand, the more complex structure of the hyper-redundant robot also challenges the more elaborate closed-loop control strategy. For these reasons, a cable-driven snake-like robot, which is compact and low cost, with force transducers and angle sensors, is designed in this article. The simpler and more direct kinematic model is studied, which applies to a widely used kinematics algorithm. Based on the kinematic model, the inverse dynamics are resolved. Finally, this article analyzes the sources of the motion errors and achieves dual-loop control through force-feedback and pose-feedback. The experiment results show that the robot’s structure and dual-loop control strategy function with high accuracy and reliability, meeting the requirements of engineering applications and high-precision control.

Effect of Long-Range Corrections on Intermolecular Interactions and Vibrational Assignments of Ethylene Oxide Dimer. A Combined DFT and SQFF Study

Theoretical structural and vibrational study for the ethylene oxide dimer have been performed by using the experimental structure determined by X-ray diffraction, the vibrational spectra and, the functional hybrids B3LYP/6-311++G** and WB97XD/6-311++G** methods. Here, the effects of dispersion on intermolecular interactions and on complete assignments of infrared and Raman spectra of dimer have been performed combining the Pulay´s scaled quantum mechanical force field (SQMFF) methodology with those two levels of calculations in order to fit the theoretical wavenumbers values to the experimental ones. Calculations including long-range corrections have revealed similar optimized energy, volume and frequencies to calculated with the B3LYP/6-31G* method, lower correlations in the geometrical parameters, higher stabilization energy, higher values in the topological parameters and higher scaled force constants than the obtained at B3LYP/6-311++G** level. Natural bond order (NBO) and atoms in molecules theory (AIM) studies with both methods reveal two types of intermolecular interactions (C-O···H and C-O···O) in the ethylene oxide dimer in accordance with the bands observed in the experimental Raman spectrum at low temperatures and with the experimental structure determined at 100 K. The nature of those interactions and their topological properties were studied by using NBO and AIM calculations. The studied properties for the ethylene oxide dimer were analyzed and compared with those obtained for the monomer. Similar assignments of the vibrational modes for dimer were obtained using the three different methods.

An Optimized Energy and Time Constraints-Based Path Planning for the Navigation of Mobile Robots Using an Intelligent Particle Swarm Optimization Technique

Mobile robots (MRs) typically require running for many hours on one charge of the battery. Electric autonomous mobile robots (AMRs) have become increasingly common in the manufacturing process in the last few years. MRs must often complete difficult assignments while gathering information across an unknown area involving energy constraints and time-sensitive preferences. This paper estimates the information collection assignment for surveillance as a multi-objective optimization dilemma with both energy and time constraints. In this study, three main objectives during acquiring data are taken into consideration, including the greatest quantity of data acquired for surveillance, following a path where obstacles are least likely to be experienced, and traveling the smallest feasible path. To obtain the optimal path for an MR by addressing the presented issue, this approach presents an intelligent particle swarm optimization (PSO) technique that determines fitness value by simplifying the optimization task for achieving the shortest path for MR navigation. It allows particles to execute variable operations while maintaining most of the prior search information. The findings of the simulation show that this technique of the PSO algorithm can realize swift convergence and high accuracy when compared with different benchmark functions derived for PSO. A comparative discussion on various energy-efficient navigation techniques for MRs is also provided. Lastly, this study describes the possible future research directions.

Microstructure evolution, crystal structure, Raman analysis, bond characteristics and enhanced microwave dielectric properties of Zn1-xCuxZrNb2O8 solid solution ceramics

The Structural factors of ceramic materials significantly affect microwave dielectric properties. Consequently, the structure–performance mechanism is essential for providing insight into material discovery and performance refinement. In the present work, Zn1-xCuxZrNb2O8 ceramics were synthesized through oxygen-assisted sintering procedures. The controversy of lattice vibrations was clarified and complete Raman vibration with complete mode assignments were provided for the first time through density functional theory and symmetry analysis. Intrinsic properties, including lattice energy, bond ionicity, thermal expansion coefficient, Raman vibrational states and bond energy, were calculated and the structure–performance relationships were established based on crystal structure refinement, density functional theory, chemical bond theory and Raman analyses. X-ray diffraction patterns and crystal structure refinement indicate a pure phase with the wolframite structure. The smaller ionic radii of Cu2+ ions led to a decrease in cell volume, which could account for the blueshift of the Ag mode at around 340 cm−1. Through Cu2+ substitution, the grain growth was further promoted and morphology evolution from polyhedral grain to rod shape was observed, which may be attributed to grain amalgamation. From chemical bond theory, Cu2+ substitution leads to the decrease in the dielectric constant, which is related to a decrease in the Nb–O bond ionicity (fiNb-O). The improvement in Q×f value is attributed to the high lattice energy of Nb–O bond (UNb–O), low FWHM at 845 cm−1 and large grain size. τf values are strongly impacted by the bond energies of the Zn/Cu–O bonds in the Zn1-xCuxZrNb2O8 ceramic crystals. Remarkably, microwave dielectric performance of the composition x = 0.06, sintered at 1175 °C, where εr = 27.9, Q×f = 73,200 GHz (@7.14 GHz) and τf = −40 ppm/°C, provide potential for millimeter-wave applications.

MT-MAG: Accurate and interpretable machine learning for complete or partial taxonomic assignments of metagenomeassembled genomes.

We propose MT-MAG, a novel machine learning-based software tool for the complete or partial hierarchically-structured taxonomic classification of metagenome-assembled genomes (MAGs). MT-MAG is alignment-free, with k-mer frequencies being the only feature used to distinguish a DNA sequence from another (herein k = 7). MT-MAG is capable of classifying large and diverse metagenomic datasets: a total of 245.68 Gbp in the training sets, and 9.6 Gbp in the test sets analyzed in this study. In addition to complete classifications, MT-MAG offers a "partial classification" option, whereby a classification at a higher taxonomic level is provided for MAGs that cannot be classified to the Species level. MT-MAG outputs complete or partial classification paths, and interpretable numerical classification confidences of its classifications, at all taxonomic ranks. To assess the performance of MT-MAG, we define a "weighted classification accuracy," with a weighting scheme reflecting the fact that partial classifications at different ranks are not equally informative. For the two benchmarking datasets analyzed (genomes from human gut microbiome species, and bacterial and archaeal genomes assembled from cow rumen metagenomic sequences), MT-MAG achieves an average of 87.32% in weighted classification accuracy. At the Species level, MT-MAG outperforms DeepMicrobes, the only other comparable software tool, by an average of 34.79% in weighted classification accuracy. In addition, MT-MAG is able to completely classify an average of 67.70% of the sequences at the Species level, compared with DeepMicrobes which only classifies 47.45%. Moreover, MT-MAG provides additional information for sequences that it could not classify at the Species level, resulting in the partial or complete classification of 95.13%, of the genomes in the datasets analyzed. Lastly, unlike other taxonomic assignment tools (e.g., GDTB-Tk), MT-MAG is an alignment-free and genetic marker-free tool, able to provide additional bioinformatics analysis to confirm existing or tentative taxonomic assignments.

ChatGPT in the English Classroom

18 students engaged in learning about artificial intelligence, specifically ChatGPT 3 (CHAT), to respond to the question of whether it is ethical or practical for students to use CHAT in college-level classrooms to complete assignments. A thematic unit was created and taught in 2 face-to-face English 101 classes to explore the topic of CHAT. The unit was created with and designed to be completed by CHAT. After reflecting on 3 readings, 2 videos, and completing various related assignments, students were expected to write a 5-page essay about CHAT using CHAT in whatever way they wanted to complete the work while still maintaining the specific requirements of the English 101 objectives. The essays were examined by the students using the same peer review process that we used for 2 essays written without using CHAT before the thematic unit, with the addition of 2 instructions: to check the veracity of the sources, and to evaluate the essays for consistency of tone, accuracy of information, and originality. Data collection for this qualitative study was based on hand-written reflections by 18 of the students in the classroom, quick polls at the end of each lesson, and semi-structured, recorded interviews with 9 of the participating students who volunteered to be recorded. The students were charged with the dual roles of tester and consultant, and it gave them the opportunity to understand and test CHAT in a classroom and to share their insights with faculty. Reflections and interviews were transcribed, coded, analyzed, and categorized into the 3 strongest recommendations for faculty considering using CHAT in their curriculum: (1) faculty should be open-minded and well trained in what CHAT is and how to use it safely before attempting to allow their students to use it in class; (2) students should be given specific instructions for how to use CHAT for specific tasks that will help them reach their potential and then allowed to decide for themselves how to proceed; (3) students should be tested to demonstrate comprehension of the material and classroom objectives both before and after the use of CHAT.

Structure and Spectral Properties of Thianthrene and Its Benzoyl-Containing Derivatives

The IR absorption spectra of the recently synthesized series of benzoyl-containing thianthrene derivatives were studied in the context of their structural identification. Geometry optimizitation of the ground singlet state by density functional theory (DFT) calculations with the gradient and Hessian search were performed for thianthrene molecule in the framework of the C2v symmetry restriction. The excited singlet and triplet states of thianthrene were found to be distorted along the b3u vibrational mode of the D2h point group, as well as the ground state, which leads to the non-planar batterfly-like structure (C2v). But the excited states require additional symmetry reduction; they are closer to planarity but have no symmetry elements. Optimized ground states structure for the thianthrene-benzoyle molecule and its four derivatives with fluoro-substituents and different substitution positions were analyzed through complete assignment of all their vibrational modes and comparison with experimental infrared absorption spectra. A good agreement between experimental data and DFT calculated IR spectra provides additional structural support to results of the X-ray diffraction analysis of all synthesized compounds. The Hirshfeld surfaces analysis of the crystalline 3-fluorobenzoyl-thianthrene (T3F) was performed in order to analyze intermolecular interactions in T3F crystal. It indicates the presence of weak CH…F, CH…S and CH…O intermolecular contacts, stabilizing the crystal structure of T3F. The CH…O interactions appear in the IR spectrum of T3F crystal as two vibrational modes with frequencies 3084 and 3078 cm–1. The intermolecular interactions CH…F and CH…S do not affect the IR spectrum of T3F.

Synthesis, spectroscopic investigations, topological non-covalent interactions, chemical reactivity, molecular docking and molecular dynamic simulation on piperazine succinate - A potential antimicrobial compound

Piperazine Succinate (PZSN) has been synthesized and extensively analyzed using various spectroscopic techniques, including FT-IR, FT-Raman and NMR spectra. In optimizing geometry, a comparison between the bond lengths of C2-H25 in PZSN (1.0999 Å) and SN (1.0938 Å) reveals an increase of 0.0061 Å in the C21-H25 bond length for PZSN. This elongation can be attributed to the significant C21-H25‧‧‧N2 intermolecular hydrogen bonding interaction. Natural bond orbital analysis of the molecule indicates a significant charge transfer between LP(1) N2 → σ* (C21-H25) leads to a substantial stabilization energy of 6.73 kcal/mol, providing strong evidence for the presence of intermolecular hydrogen bonding interactions. The strong band observed in the IR spectrum at 3510 cm−1, assigned to N2-H16 stretching mode, which clearly supports the formation of a hydrogen bond between succinate C=O and piperazine NH group. The complete vibrational assignments and the force constants has been reported for PZSN by using B3LYP/6–311++G** method. Molecular parameters, such as Frontier Molecular Orbital (FMO) energies, Fukui functions and Molecular Electrostatic Potential (MEP), have been calculated to gain insights into the stability and reactivity of the molecule. According to the QTAIM analysis, the presence of a strong non-bonded interaction is supported by the largest interaction energy observed at the C21-H25‧‧‧N2 bond critical point (BCP), which is 3.42 kcal/mol. Furthermore, Reduced Density Gradient (RDG) and Independent Gradient Model (IGM) approaches have been performed to disclose the attractive contacts like hydrogen bonds, repulsive and van der Waals interconnections. The molecule's drug-likeness has been assessed using Lipinski's rule and ADMET contour analysis indicated its potential for pharmaceutical applications. Molecular docking modeling have been conducted on antimicrobial proteins to explore the structure-activity relationship and antimicrobial testing confirmed the molecule's efficacy against microbial infections. Molecular dynamic simulations have been utilized to examine the stability of protein-ligand complex.
