description: We observed the coulomb blockade phenomena in ferromagnetic contacting single wall semiconducting carbon nanotube devices. No obvious Coulomb peaks shift was observed with existing only the Zeeman splitting at 4K. Combining with other effects, the ferromagnetic leads prevent the orbital spin states splitting with magnetic field up to 2 Tesla at 4K. With increasing magnetic field further, both positive or negative coulomb peaks shift slopes are observed associating with clockwise and anticlockwise orbital state splitting. The strongly suppressed/enhanced of the conductance has been observed associating with the magnetic field induced orbital states splitting/converging.

description: Criminal violence is one of the most pressing problems in Latin America and the Caribbean, with profound political consequences. Its effects on social policy preferences, however, remain largely unexplored. This article argues that to understand such effects it is crucial to analyze victimization experiences and perceptions of insecurity as separate phenomena with distinct attitudinal consequences. Heightened perceptions of insecurity are associated with a reduced demand for public welfare provision, as such perceptions reflect a sense of the state’s failure to provide public security. At the same time, acknowledging the mounting costs and needs that direct experience with crime entails, victimization is expected to increase support for social policies, particularly for health services. Survey data from twenty-four Latin American and Caribbean countries for the period 2008–12 show that perceptions of insecurity indeed reduce support for the state’s role in welfare provision, whereas crime victimization strongly increases such preferences.

description: We investigate a hierarchical surface structuring process to reduce the optical reflectance of monocrystalline Si solar cells to below the reflectance of state-of-the-art alkaline texturing. First, alkaline texturing is performed, yielding random pyramids with a few micrometers in size. Second, plasma etching forms step-shaped structures smaller than the wavelength of visible light. Eventually, the surface morphology is formed by <111> planes with many steps, edges and inverted pyramids in a few hundreds of nanometers scale. We investigate the reflectance on double-side textured samples with SiNx/Al2O3 front-side and SiNx rear-side passivation. These dielectric stacks exhibit a low reflectance for conventional alkaline textured surfaces. The short circuit current density potential of the best hierarchical structured samples is 0.4 mA/cm2 higher when integrating the AM1.5G spectrum from 300nm to 1000 nm. Furthermore, our results suggest that structures with dimensions smaller than the thickness of an antireflection- and passivation (AR) layer cannot be covered conformal by the AR layer when using plasma-enhanced chemical vapor deposition. Thus, there seems to be a lower limit for the structure size, and wet chemical cleaning sequences – performed after plasma etching - have to be adjusted accordingly.

description: A green and facile synthesis of 1-(α-aminoalkyl)-2-naphthols, generally called Betti bases (BB) in the presence of Baker’s yeast (BY), acts as an efficient catalyst, and ethanol as a green solvent. In this methodology, the BY is used first time as a biocatalyst (enzyme). This protocol has some inherent advantages, such as mild reaction conditions, no environmental pollution, simple work up, no need of column chromatography, diversity of reactant and desired 1-(α-aminoalkyl)-2-naphthols (Betti bases) (4a-r) are obtained in good-to-excellent yields. This is the first report on Baker’s yeast-catalyzed (BYC) synthesis for BB. This present bio-catalytical route for synthesizing BB in the presence of biocatalysts like BY is anticipated to open a gateway to synthesized complexed biological active molecules counting BB.

description: To every cubic hypersurface $X$ we associate the parameter space of lines contained in $X$; this is called the Fano scheme of lines on $X$ and denoted $F(X)$. If X admits an isolated singular point of ADE-type, we prove that $F(X)$ admits hypersurface singularities of the same type transversally along the regular part of its singular locus. As was shown by H. Clemens and P. Griffiths, the Albanese variety $\operatorname{Alb}(F(X))$ of the Fano scheme of lines $F(X)$ on a smooth cubic threefold $X$ is isomorphic to the intermediate Jacobian $IJ(X)$ of $X$. G. van der Geer and A. Kouvidakis generalised this result to nodal cubic threefolds, replacing the Albanese variety $\operatorname{Alb}(F(X))$ by the Picard scheme $\operatorname{Pic}^0(F(X))$. We study more generally degenerations of the Picard scheme $\operatorname{Pic}^0(F(X))$ when the smooth cubic threefold $X$ degenerates to a cubic threefold with unique singular point of type $A_k$ and prove that these degenerations define points in Mumford’s partial compactification $\mathcal{A}_5'$ of the moduli space $\mathcal{A}_5$ of principally polarised Abelian varieties of genus five.

description: We propose a Lorentz-covariant Yang-Mills spin-gauge theory, where the function valued Dirac matrices play the role of a non-scalar Higgs-field. As symmetry group we choose $SU(2) \times U(1)$. After symmetry breaking a non-scalar Lorentz-covariant Higgs-field gravity appears, which can be interpreted within a classical limit as Einstein's metrical theory of gravity, where we restrict ourselves in a first step to its linearized version.

Distributed Parametric Effect in Long Lines and its Applications

Publisher: name: arXiv
Year: 2012
Subjects: subject: General Physics (physics.gen-ph)
subject: FOS: Physical sciences

description: The article considers a parametric effect which takes place when the velocity of signal propagation in a long line changes. We found the analytical solution describing the form of the transformed signal for a line with losses, when line parameters change symmetrically. We also considered lines without losses, with asymmetrical change of parameters. Our theoretical results comply with experimental data. In certain conditions, such a line can be used as an amplifier. The parametric effect in optics is described by Maxwell's equations, while in case of a long line, the analysis is based on telegrapher's equations. However, it turns out that in the end, both in optics and electronics, the parametric effect is described by wave equations that are mathematically similar. This is because fundamentally, the parametric effect is physically based on energy interchange between the controlling (pump) signal and the transformed one, when the parameters of the propagating medium change. So, the obtained results can be used for analysis of parametric effects in optics and electronics.

description: Microfluidics is a rapidly growing discipline that involves studying and manipulating fluids at reduced length scale and volume, typically on the scale of micro- or nanoliters. Under the reduced length scale and larger surface-to-volume ratio, advantages of low reagent consumption, faster reaction kinetics, and more compact systems are evident in microfluidics. However, miniaturization of microfluidic chips and systems introduces challenges of stricter tolerances in designing and controlling them for interdisciplinary applications. Recent advances in artificial intelligence (AI) have brought innovation to microfluidics from design, simulation, automation, and optimization to bioanalysis and data analytics. In microfluidics, the Navier–Stokes equations, which are partial differential equations describing viscous fluid motion that in complete form are known to not have a general analytical solution, can be simplified and have fair performance through numerical approximation due to low inertia and laminar flow. Approximation using neural networks trained by rules of physical knowledge introduces a new possibility to predict the physicochemical nature. The combination of microfluidics and automation can produce large amounts of data, where features and patterns that are difficult to discern by a human can be extracted by machine learning. Therefore, integration with AI introduces the potential to revolutionize the microfluidic workflow by enabling the precision control and automation of data analysis. Deployment of smart microfluidics may be tremendously beneficial in various applications in the future, including high-throughput drug discovery, rapid point-of-care-testing (POCT), and personalized medicine. In this review, we summarize key microfluidic advances integrated with AI and discuss the outlook and possibilities of combining AI and microfluidics.

description: This paper presents the results of a series of penetration tests performed on the OpenStack Essex Cloud Management Software. Several different types of penetration tests were performed including network protocol and command line fuzzing, session hijacking and credential theft. Using these techniques exploitable vulnerabilities were discovered that could enable an attacker to gain access to restricted information contained on the OpenStack server, or to gain full administrative privileges on the server. Key recommendations to address these vulnerabilities are to use a secure protocol, such as HTTPS, for communications between a cloud user and the OpenStack Horizon Dashboard, to encrypt all files that store user or administrative login credentials, and to correct a software bug found in the OpenStack Cinder typedelete command.

description: In order to study the connection between structure of the molecular and sensitizing performance in dye-sensitized solar cells, four new organic sensitizers with donor-pi spacer-acceptor structures were designed and synthesized. The structural characterization of all dye sensitizers was investigated using FT-IR, 13C and 1H NMR, CHN and UV–visible analyses. The electronic orbital transitions and optical properties were determined and discussed. (E)-2-cyano-3-(5-(3-(di-p-tolylamino)phenyl)furan-2-yl)acrylic acid (TPCA), (Z)-2-cyano-N′-((5-(3-(di-p-tolylamino)phenyl)furan-2-yl)acetohydrazide (TPCH), (E)-3-(5-(4-(bis(4-methoxyphenyl)amino)phenyl)furan-2-yl)-2-cyanoacrylic acid (MTPCA), and (Z)-N′-((5-(4-(bis(4-methoxyphenyl)amino)phenyl)furan-2-yl)methylene)-2-cyanoacetohydrazide exhibited band gaps (Egap) in the range from 1.51 to 1.78 eV with λabs in the range of 486–589 nm. The dyes’ energy levels were investigated using the cyclic voltammetry technique and DFT calculations. To complement the comprehensive optical, electrochemical, and photovoltaic properties, density functional theory studies were conducted. Besides, important parameters such as open-circuit voltage, light harvesting efficiency, and band gap energy of the dye sensitizers were calculated and discussed. The theoretically calculated open-circuit voltage (Voc) values ranged from 1.28 to 2.04 eV, while the light-harvesting efficiency (LHE) values varied from 0.11 to 0.22. Indeed, this theoretical research could guide chemists to synthesize effective dyes for DSSCs.

description: In this study, a new deep eutectic mixture (DEM) was prepared from D-fructose, L-arginine, and urea and characterized by Fourier transform infrared (FT-IR), refractive index measurement, and thermogravimetric analysis (TGA). In continue this mixture was used as a green catalyst to promote the synthesis of three important derivatives of heterocyclic compounds. The highlights of this work include some notable advantages such as ease of the preparation and simple catalytic process, low cost, green reaction conditions, biodegradability of the catalyst, short reaction times, high yields of the products and simple work-up. Also, the catalyst could be recovered easily and reused up to several times without significant loss of catalytic activity.

description: A biodegradable catalyst based on natural deep eutectic solvents (NaDESs) designed from Betaine and natural acids (Betaine: Citric Acid: H2O) with a molar ratio of (1:1.5:1) has been utilized in one-pot multi-component reaction for the synthesis of Isoxazol-5-ones derivatives in a mild, green and efficient manner. The reaction was carried out under different conditions that are, at 400C, ultrasonic and microwave. The developed method provided many advantages, including an excellent yield of up to 98% in a shorter reaction time, avoiding the use of toxic solvents and an easy handling process. Additionally, the use of NaDESs enabled the conservation of resources due to their simple preparation. The developed process adheres to the requirements of green chemistry by employing a bio-sourced and recyclable catalyst.

description: We construct, for the first time, various types of specific non-special finite $p$-groups having abelian automorphism group. More specifically, we construct groups $G$ with abelian automorphism group such that $γ_2(G) < \mathrm{Z}(G) < Φ(G)$, where $γ_2(G)$, $\mathrm{Z}(G)$ and $Φ(G)$ denote the commutator subgroup, the center and the Frattini subgroup of $G$ respectively. For a finite $p$-group $G$ with elementary abelian automorphism group, we show that at least one of the following two conditions holds true: (i) $\mathrm{Z}(G) = Φ(G)$ is elementary abelian; (ii) $γ_2(G) = Φ(G)$ is elementary abelian, where $p$ is an odd prime. We construct examples to show the existence of groups $G$ with elementary abelian automorphism group for which exactly one of the above two conditions holds true.

description: In the field of applied mathematics the Fourier transform has developed into an important tool. It is a powerful method for solving partial differential equations. The Fourier transform provides also a technique for signal analysis where the signal from the original domain is transformed to the spectral or frequency domain. In the frequency domain many characteristics of the signal are revealed. With these facts in mind, we extend the Fourier transform in geometric algebra. We explicitly show detailed properties of the real Clifford geometric algebra Fourier transform (CFT), which we subsequently use to define and prove the uncertainty principle for Cl(3,0) multivector functions.

description: In the search for new leads capable of interacting with multiple targets involved in NDD pathogenesis, a series of pyrazine-linked isoxazoline scaffolds were designed, synthesized and evaluated for their acetylcholinesterase and tyrosinase inhibitory potency and antioxidant activity. Isoxazolines 4a, 4d and 4h exhibited better molecular interaction with cholinesterases, tyrosinases and peroxiredoxin enzymes. Isoxazolines 4a, 4d and 4h interacted with acetylcholinesterase with the highest docking score of −9.083, −8.68 and −7.87 kcal/mol, respectively. Compound 4h ranked top when interacting with butyrylcholinesterase with a docking score of −7.926 kcal/mol, followed by 4a (−6.327 kcal/mol). 4a exhibited a robust interaction with 1HD2 with a docking score of −3.103 kcal/mol followed by 4d and 4h. 4a, 4d and 4h exhibited better docking scores of −5.47 kcal/mol, −4.63 kcal/mol and −5.157 kcal/mol with the enzyme tyrosinase. Based on the in-silico data, we have proceeded further to synthesis and in-vitro studies. Chalcones were synthesized by the Claisen-Schmidt reaction, which was cyclised to isoxazolines by the cycloaddition of hydroxylamine HCl. FTIR, 1HNMR, 13CNMR, and mass spectral studies further characterized the compounds. The prediction of pharmacokinetic parameters also supports the study, and all the compounds passed the screening. In-vitro studies were performed to evaluate acetylcholinesterase and tyrosinase inhibition. Compound 4h displayed excellent action against acetylcholinesterases and tyrosinase enzymes. Hydrogen peroxide assay determined the antioxidant effect, which found that 4h and 4d compounds exhibited higher strength as peroxide scavengers. Thus, the study shows that pyrazine-based isoxazolines with electron-withdrawing groups can be used as leads to develop a drug of choice for NDD, as it has excellent acetylcholinesterase and tyrosinase inhibitory action and tremendous peroxide scavenging effect.

description: The unique quantum properties of the nitrogen-vacancy (NV) center in diamond have motivated efforts to find defects with similar properties in silicon carbide (SiC), which can extend the functionality of such systems not available to the diamond. Electron paramagnetic resonance (EPR) and optically detected magnetic resonance (ODMR) investigations presented here suggest that silicon vacancy (VSi) related point defects in SiC possess properties the similar to those of the NV center in diamond, which in turn make them a promising quantum system for single-defect and single-photon spectroscopy in the infrared region. Depending on the defect type, temperature, SiC polytype, and crystalline position, two opposite schemes have been observed for the optical alignment of the ground state spin sublevels population of the VSi-related defects upon irradiation with unpolarized light. Spin ensemble of VSi-related defects are shown to be prepared in a coherent superposition of the spin states even at room temperature. Zero-field ODMR shows the possibility to manipulate of the ground state spin population by applying radiofrequency field. These altogether make VSi-related defects in SiC very favorable candidate for spintronics, quantum information processing, and magnetometry.

Проведен эксперимент на поросятах, полученных при трехпородной системе скрещи-вания (ландрас × крупная белая × дюрок). Были сформированы 2 группы поросят: контрольная и опытная. Скармливание оригинальной добавки в составе комбикорма по сравнению с контролем позволило на 15,4 % (р<0,05) повысить среднесуточные приросты живой массы поросят. Применение добавки обеспечивало значительное снижение затрат кормов на 1 кг прироста живой массы по сравнению с контролем.
description: the aim of the work was the development of the original feed supplement for 60-120 day old piglets, as well as a method for increasing the bioconversion of feed protein into meat components and improving its quality. An experiment was car-ried out on piglets obtained from a three-breed crossing system (Landrace × Large white × Duroc). Two groups of piglets were formed: control and experimental. Feeding the original additive in the composition of the feed compared to the control allowed to increase the average daily live weight gain of the piglets by 15.4% (p <0.05). The use of the additive provided a significant reduction in the cost of feed per 1 kg of weight gain compared to the control.

description: This work presents a non-parametric spatiotemporal model for mapping human activity by mobile autonomous robots in a long-term context. Based on Variational Gaussian Process Regression, the model incorporates prior information of spatial and temporal-periodic dependencies to create a continuous representation of human occurrences. The inhomogeneous data distribution resulting from movements of the robot is included in the model via a heteroscedastic likelihood function and can be accounted for as predictive uncertainty. Using a sparse formulation, data sets over multiple weeks and several hundred square meters can be used for model creation. The experimental evaluation, based on multi-week data sets, demonstrates that the proposed approach outperforms the state of the art both in terms of predictive quality and subsequent path planning.© 2022 IEEE.

description: Variable stiffness actuator (VSA) designs are manifold. Conventional model-based control of these nonlinear systems is associated with high effort and design-dependent assumptions. In contrast, machine learning offers a promising alternative as models are trained on real measured data and nonlinearities are inherently taken into account. Our work presents a universal, learning-based approach for position and stiffness control of soft actuators. After introducing a soft pneumatic VSA, the model is learned with input-output data. For this purpose, a test bench was set up which enables automated measurement of the variable joint stiffness. During control, Gaussian processes are used to predict pressures for achieving desired position and stiffness. The feedforward error is on average 11.5% of the total pressure range and is compensated by feedback control. Experiments with the soft actuator show that the learning-based approach allows continuous adjustment of position and stiffness without model knowledge.© 2023 IEEE.

description: Soft robotic manipulators are on the verge to their first real applications. In most cases they are actuated by fluidic pressure or tendons and molded of highly elastic material, which performs large deformation if put under stress. Performing tasks e.g. in inspection of narrow machines or endoscopy requires the actuator to be tactile and controllable. Due to their highly nonlinear behavior, model-based approaches are investigated to combine and utilize sensor information to estimate the system states of the manipulator. In this paper, equations of motion (EoM) for the well-known piecewise constant curvature (PCC) approach are extended by a floating base as it is often used in kinematic chains for legged robots and their contact with the ground. Base reaction forces and moments, which are easily measurable quantities, become visible in the EoM, if the six spatial degrees of freedom at the base of the manipulator are considered. Thereby, additional information on the system's states is obtained and used in the proposed identification scheme. Essentially, the floating base, a center-of-gravity approach and a state-of-the-art parametrization of the PCC kinematics are combined to derive and validate a Lagrangian dynamics model. On a best-case set of validation step responses, the identified inverse dynamics model performs with an accuracy of 5% to 7.6% of max. actuation torque.© 2022 IEEE.

description: The formation of inclusion complexes of 2-hydroxypropyl-β-cyclodextrin (HP β-CD) with 2-hydroxychalcone (2HOCH) in solution and solid state was investigated using UV–Visible, fluorescence, Fourier transform-infrared (FT-IR) spectroscopy, powder X-ray diffraction (PXRD), scanning electron microscope (SEM) techniques. The results obtained confirmed that 2HOCH formed the stable inclusion complex with HP β-CD. Moreover, the spectral data and Benesi–Hildebrand plots results indicated that the stoichiometry of the inclusion complex was 1:1. Theoretically, the structure of the inclusion complexes and the physical parameters such as complexation energy, highest occupied molecular orbital–lowest unoccupied molecular orbital, and energy gap were obtained using the DFT/B3LYP/6-311G method. It was found that the complexation energy for orientation B was lower than that for orientation A as evidenced by the theoretical calculations. Moreover, the carbonyl group of molecules was located outside of the cyclodextrin cavity while the hydroxyl group was located inside the cavity. The antioxidant capacity and antibacterial responses of the inclusion complexes and, for comparison, the parent compounds were also carried out.

description: Seagrasses represent an essential part of the coastal environment and are hence the target of many coastal restoration projects. Artificial seagrass (ASG) mats may facilitate seagrass growth, making them a captivating option for restoration projects. However, little is known about the forces occurring on mats deployed in marine environments and especially on how these forces are transmitted to the anchoring points. Here, we present a study of prototype biodegradable coconut-mesh mats as base layer for ASG meadows and investigate the forces that occur at the anchors. We test the performance of three mesh types under wave forcing using two different anchor configurations without ASG and subsequently test ASG mats of one mesh type under wave forcing and a 4-anchor configuration to assess the effect of the ASG on anchor loading as a function of incident orbital velocities. We found that the mat composition plays a more important role than the number of anchors in anchor load reduction. The anchor forces were 2–4 times higher at front anchors compared to rear anchors, relative to wave propagation direction, and were also considerably higher in that direction compared to the opposite direction. With ASG, the forces increased compared to the highest measured forces without ASG. The forces on the anchors were almost fully dominated by the drag on the ASG based on material properties, ASG reconfiguration and flow conditions. We derive a relation between horizontal orbital velocities and expected forcing on the anchor based on ASG properties and the corresponding area of each anchor and discuss relevant criteria for the design of ASG mats. This should help to assess the loading on anchors deployed for restoration under specific site conditions and chosen materials. Copyright © 2022 Villanueva, Paul and Schlurmann.

description: In this work, theoretical and experimental studies of a new Indazole derivative named 2-(5-nitro-1-H-indazol-1-yl) acetic acid (3), including the synthesis and characterization by 1H and 13C-NMR, FT-IR, UV spectroscopies are reported together with its X-ray crystal structure. The compound crystallizes in the monoclinic crystal system of P21/c space group and unit cell constants: a = 7.8541(10) Å, b = 7.9274(11) Å, c = 15.877(2) Å, β = 101.149(5)°. In the crystal, O–H···N and C–H···O hydrogen bonds form a 3-D network structure containing small channels running parallel to the b-axis. B3LYP/6-311++G** calculations in the gas phase and ethanol solution suggest the existence of C1 and C2 conformers where the structure of C1 in both media is in agreement with that observed by X-ray diffraction. Probably, the high values observed in the dipole moments of C1 justify its presence in gas and solution phases. The stabilities of both forms were justified by NBO and AIM calculations where C1 is more stable than C2. C1 shows a higher solvation energy, dipole moment, and higher hydration than C2 while the frontier orbitals suggest a higher reactivity of C1 over C2. Force fields and complete vibrational assignments were performed for the C1 conformer because it was detected in the solid phase. Scaled force constants for both forms are also reported. Calculated chemical shifts for (3) are consistent with the experimental 1H and 13C-NMR spectra in the DMSO-d6 solution. The anti-COVID activity of 3 is investigated by its molecular docking into the binding site of SARS CoV-2 3CLpro (3 C-like protease). It shows a moderate binding affinity into the binding site of 3 C-like protease with a maximum binding energy of −5.57 kcal mol−1.

description: Very recently, molecular rotational transitions observed in the photon-dominated region of the Horsehead nebula have been attributed to l-C3H+. In an effort to corroborate this finding, we employed state-of-the art and proven high-accuracy quantum chemical techniques to compute spectroscopic constants for this cation and its isotopologues. Even though the B rotational constant from the fit of the observed spectrum and our computations agree to within 20 MHz, a typical level of accuracy, the D rotational constant differs by more than 40%, while the H rotational constant differs by three orders of magnitude. With the likely errors in the rotational transition energies resulting from this difference in D on the order of 1 MHz for the lowest observed transition (J = 4
