description: We consider the two scalar field cosmology in a FRW spatially flat spacetime where the scalar fields interact both in the kinetic part and the potential. We apply the Noether point symmetries in order to define the interaction of the scalar fields. We use the point symmetries in order to write the field equations in the normal coordinates and we find that the Lagrangian of the field equations which admits at least three Noether point symmetries describes linear Newtonian systems. Furthermore, by using the corresponding conservation laws we find exact solutions of the field equations. Finally, we generalize our results to the case of N scalar fields interacting both in their potential and their kinematic part in a flat FRW background.

description: In this work we have studied the nonlinear preheating dynamics of the $\frac{1}{4} λϕ^4$ inflationary model. It is well established that after a linear stage of preheating characterized by the parametric resonance, the nonlinear dynamics becomes relevant driving the system towards turbulence. Wave turbulence is the appropriated description of this phase since matter distributions are fields instead of usual fluids. Therefore, turbulence develops due to the nonlinear interations of waves, here represented by the small inhomogeneities of the inflaton field. We present relevant aspects of wave turbulence such as the Kolmogorov-Zakharov spectrum in frequency and wave number domains that indicates that there are a transfer of energy through scales. From the power spectrum of the matter energy density we were able to estimate the temperature of the thermalized system.

description: I dati raccolti negli scavi stratigrafici (1993-2014) condotti nel sito del castelliere del Guardamonte (AL-PV), frequentato dal Neolitico alla romanizzazione, permettono oggi di condurre ricerche strutturate su diversi aspetti dei cicli produttivi, in un'ottica diacronica, contestuale ed ecologica. Qui si presentano i risultati finora raggiunti tramite l'applicazione di un protocollo di studio della produzione ceramica che, pur avvalendosi di collaborazioni multidisciplinari, stato metodologicamente ragionato sulla base di istanze prettamente archeologiche. Tale protocollo articolato in tre linee di ricerca, tra loro costantemente integrate: “studio ceramologico” (individuazione dei bacini di approvvigionamento tramite analisi geologiche del territorio, analisi delle tecniche di foggiatura, classificazione dei corpi ceramici tramite studio autopticofunzionale), “analisi archeometriche preliminari” (con tecnologie SEM-EDS e XRD) e “prove archeosperimentali” (prove di lavorabilit delle argille locali, ricostruzioni di forni, prove di cottura).

Extended two-dimensional characteristic framework to study nonrotating black holes

Publisher: name: arXiv
Year: 2014
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: We develop a numerical solver, that extends the computational framework considered in [Phys. Rev. D 65, 084016 (2002)], to include scalar perturbations of nonrotating black holes. The nonlinear Einstein-Klein-Gordon equations for a massless scalar field minimally coupled to gravity are solved in two spatial dimensions (2D). The numerical procedure is based on the ingoing light cone formulation for an axially and reflection symmetric spacetime. The solver is second order accurate and was validated in different ways. We use for calibration an auxiliary 1D solver with the same initial and boundary conditions and the same evolution algorithm. We reproduce the quasinormal modes for the massless scalar field harmonics $\ell = 0$, $1$ and $2$. For these same harmonics, in the linear approximation, we calculate the balance of energy between the black hole and the world tube. As an example of nonlinear harmonic generation, we show the distortion of a marginally trapped two-surface approximated as a q-boundary and based upon the harmonic $\ell=2$. Additionally, we study the evolution of the $\ell = 8$ harmonic in order to test the solver in a spacetime with a complex angular structure. Further applications and extensions are briefly discussed.

description: We investigate optimization strategies to measure primordial non-Gaussianity with future spectroscopic surveys. We forecast measurements coming from the 3D galaxy power spectrum and compute constraints on primordial non-Gaussianity parameters f_NL and n_NG. After studying the dependence on those parameters upon survey specifications such as redshift range, area, number density, we assume a reference mock survey and investigate the trade-off between number density and area surveyed. We then define the observational requirements to reach the detection of f_NL of order 1. Our results show that while power spectrum constraints on non-Gaussianity from future spectroscopic surveys can be competitive with current CMB limits, measurements from higher-order statistics will be needed to reach a sub unity precision in the measurements of the non-Gaussianity parameter f_NL.

description: Chalcone is a naturally derived compound which has well-known for its antimicrobial potency. Different factors reduced the efficiency of drug derivatives effective drugs always remain in demand. In this present work, bioisosteric replacement of carboxyl group is described in 1a–h, 2a–h, 3a–h and 4a–h) via microwave-assisted synthesis with excellent yields (46.76–94.59%). The antimicrobial evaluation against S. aureus depicted excellent inhibition of 1b, 1h and 3a–h with higher inhibition zones (11–18 mm) compared to that of ampicillin (11 mm). The structure-activity relationship was supported by molecular docking studies of 1b and 3h on S. aureus 4-pql protein with the binding affinity of −6.7 and −7.8 kcal/mol respectively. The DFT studies depicted the energy gap (ΔE) values 4.12 eV and 4.48 eV for compounds 1b and 3h, respectively. The presence of electron-withdrawing group (EWG) of fluorine substituent on the pyrazoline network has increased the antimicrobial activity as compared to chalcone derivatives. This study is profitable to medicinal industries in designing new drugs that benefit mankind.

description: Various programs aimed at exploring the still largely unknown low surface brightness Universe with deep imaging optical surveys have recently started. They open a new window for studies of galaxy evolution, pushing the technique of galactic archeology outside the Local Group (LG). The method, based on the detection and analysis of the diffuse light emitted by collisional debris or extended stellar halos (rather than on stellar counts as done for LG systems), faces however a number of technical difficulties, like the contamination of the images by reflection halos and Galactic cirrus. I review here the on-going efforts to address them and highlight the preliminary promising results obtained with a systematic survey with MegaCam on the CFHT of nearby massive early-type galaxies done as part of the Atlas3D, NGVS and MATLAS collaborations.

description: Traffic prediction plays a crucial role in alleviating traffic congestion which represents a critical problem globally, resulting in negative consequences such as lost hours of additional travel time and increased fuel consumption. Integrating emerging technologies into transportation systems provides opportunities for improving traffic prediction significantly and brings about new research problems. In order to lay the foundation for understanding the open research challenges in traffic prediction, this survey aims to provide a comprehensive overview of traffic prediction methodologies. Specifically, we focus on the recent advances and emerging research opportunities in Artificial Intelligence (AI)-based traffic prediction methods, due to their recent success and potential in traffic prediction, with an emphasis on multivariate traffic time series modeling. We first provide a list and explanation of the various data types and resources used in the literature. Next, the essential data preprocessing methods within the traffic prediction context are categorized, and the prediction methods and applications are subsequently summarized. Lastly, we present primary research challenges in traffic prediction and discuss some directions for future research.

description: We have calculated, within the framework of the Boltzmann equation, a dc electric current and emf in a two-dimensional system induced by the high-frequency field of an electromagnetic wave or the electric field of a plasmon wave. It is established that the generated current consists of two contributions, one of which is proportional to the real part of the wave vector projection of the exciting wave onto the interface plane and represents the electron drag effect, and the other contribution is proportional to the extinction coefficient of the wave in the interface plane. It is shown that the main cause of the second contribution is a nonuniform electron heating created by the wave and controlled by the energy relaxation time of the electron gas. In FET the heating mechanism of the electric-current formation can remarkably exceed the current calculated neglecting the heating.

description: It is the aim of the ATHENA project to support especially museums in providing object data for publication in the Europeana Initiative. However, it is known that in the museum landscape in particular there is a great variety of standards used. It was therefore necessary to gain an overview of the different standards which are in use with the partners in the ATHENA project.
 Therefore a survey has been carried out by Working Group 3 of ATHENA and the results were published within one of the deliverables of the project (http://www.athenaeurope.org/getFile.php?id=396). When discussing standards within the community we realised that there is a wider interest in the overview gained and we therefore decided to publish the overview in the form of this special booklet. Its content results from the information provided from the more than 20 partners from ATHENA coming from museums,
 libraries and archives, as well as ministries. Although it is not a complete list of standards currently available and is not covering every sector relevant, we hope it is of practical information for all those interested, as well as instrumental in building more bridges in standards applications
 for increased interoperability within the cultural heritage sector. This is the Russian language version of this deliverable.

description: A relatively shorter procedure for the synthesis of 3-amino-2-methyl-3H-quinazolin-4-one (4) was developed. The subsequent condensation reaction of 4 with a variety of aldehydes afforded several novel Schiff bases (5a-r) counting its molecular hybridization with the indole, thiophene, and quinoline pharmacophoric units. Full structural elucidation of all Schiff bases was conducted with the help of 1H and 13C NMR coupled with two-dimensional (HMBC, HSQC and COSY) techniques, and provides a reference point for the structural characterization of all the future synthesized scaffolds with a similar core structure. Furthermore, the antibacterial screening of all Schiff bases was undertaken using four Gram-negative strains, Pseudomonas aeruginosa, Escherichia coli, Klebsiella pneumonia and Salmonella typhimurium, and two Gram positive-strains, Staphylococcus aureus, and methicillin-resistant Staphylococcus aureus (MRSA). In general, several compounds showed activity against MRSA.

description: In the process of a search for new compounds to reduce hyperglycemia by α-amylase and α-glucosidase enzyme inhibition, a series of imidazole appended phenoxyquinoline derivatives were synthesized. Initially, 2-cholo-3-formyl quinoline 3 was treated with various substituted phenol in the presence of K2CO3 in DMF to get 2-phenoxyquinoline-3-carbaldehyde which in turn was treated with o-phenylenediamine to afford the corresponding 3-(1H-benzo[d]imidazol-2-yl)-2-phenoxyquinolines (7a–j). All the synthesized compounds were evaluated for their in vitro and in silico α-amylase and α-glucosidase inhibitory activity using acarbose as a standard. Among the tested compounds, compound 7a was found to exhibit a potent binding affinity; and inhibitory activity (80.90% and 76.26%) with corresponding IC50 values of 104.30 ± 3.31 μmol/mL and 135.67 ± 2.80 μmol/mL toward α-amylase and α-glucosidase, respectively.

description: We report numerical results which show the achievement of net transport of self-propelled particles (SPP) in the presence of a two-dimensional regular array of convex, either symmetric or asymmetric, rigid obstacles. The repulsive inter-particle (soft disks) and particle-obstacle interactions present no alignment rule. We find that SPP present a vortex-type motion around convex symmetric obstacles even in the absence of hydrodynamic effects. Such a motion is not observed for a single SPP, but is a consequence of the collective motion of SPP around the obstacles. An steady particle current is spontaneously established in an array of non-symmetric convex obstacle (which presents no cavity in which particles may be trapped in), and in the absence of an external field. Our results are mainly a consequence of the tendency of the self-propelled particles to attach to solid surfaces.

description: We introduce certain lattice sums associated with hyperplane arrangements, which are (multiple) sums running over integers, and can be regarded as generalizations of certain linear combinations of zeta-functions of root systems. We also introduce generating functions of special values of those lattice sums, and study their properties by virtue of the theory of convex polytopes. Consequently we evaluate special values of those lattice sums, especially certain special values of zeta-functions of root systems and their affine analogues. In some special cases it is possible to treat sums running over positive integers, which may be regarded as zeta-functions associated with hyperplane arrangements.

description: In this study, acetovanillone-derived novel benzyl ethers were synthesized as target compounds. For the synthesis of these target compounds, ketone derivatives (3a–b) were synthesized as the starting compounds. Compounds 4a–b, which are alcohol derivatives, were then synthesized from the reduction of these ketone derivatives. In the last stage of the synthesis study, benzyl ether derivatives (6a–h, 7a–h), the target compounds containing acetovanillone, were synthesized from the reaction of the alcohol derivatives (4a–b) with various benzyl halides (5a–h). The structures of the synthesized compounds were characterized by various spectroscopic methods (FT-IR, 1H NMR, 13C NMR, mass spectrometry, and elemental analysis). In vitro antileishmanial and antibacterial activity tests were then performed for all synthesized compounds. Biological activity tests showed that while only a few of the compounds had antileishmanial activity, most had antibacterial activity. In addition, the ADME parameters, pharmacokinetic properties, and drug-like nature of all compounds were theoretically investigated using the SwissADME webserver. Finally, molecular docking simulations were carried out to support in vitro investigations and evaluate the inhibition effect of the synthesized compounds on the 3IW2 (Mycobacterium tuberculosis (Mtb) Cyp125; Pdb ID: 3IW2) receptor structure. Also, possible binding sites of some compounds with high affinity to Mtb Cyp125 according to docking results were identified.
NiTi shape-memory transformations: minimum-energy pathways between austenite, martensites, and kinetically-limited intermediate states

description: NiTi is the most used shape-memory alloy, nonetheless, a lack of understanding remains regarding the associated structures and transitions, including their barriers. Using a generalized solid-state nudge elastic band (GSSNEB) method implemented via density-functional theory, we detail the structural transformations in NiTi relevant to shape memory: those between body-centered orthorhombic (BCO) groundstate and a newly identified stable austenite ("glassy" B2-like) structure, including energy barriers (hysteresis) and intermediate structures (observed as a kinetically limited R-phase), and between martensite variants (BCO orientations). All results are in good agreement with available experiment. We contrast the austenite results to those from the often-assumed, but unstable B2. These high- and low-temperature structures and structural transformations provide much needed atomic-scale detail for transitions responsible for NiTi shape-memory effects.

description: We show that an ensemble of organic dye molecules with permanent electric dipole moments embedded in a microcavity can lead to strong optical nonlinearities at the single photon level. The strong long-range electrostatic interaction between chromophores due to their permanent dipoles introduces the desired nonlinearity of the light-matter coupling in the microcavity. We obtain the absorption spectra of a weak probe field under the influence of strong exciton-photon coupling with the cavity field. Using realistic parameters, we demonstrate that a single cavity photon can significantly modify the absorptive and dispersive response of the medium to a probe photon at a different frequency. Finally, we show that the system is in the regime of cavity-induced transparency with a broad transparency window for dye dimers. We illustrate our findings using pseudoisocyanine chloride (PIC) J-aggregates in currently-available optical microcavities.

description: Herein, we have designed and synthesized sixteen novel 2,3-diarylthiazolidin-4-one derivatives 6a-p and tested their activity as α-Glucosidase inhibitors. Target compounds 6a-p were characterized using spectroscopic methods (1H-NMR, 13C-NMR, MS, IR), elemental analysis, and melting point. α-Glucosidase inhibition activity was evaluated using the α-Glucosidase enzyme inhibition kit. All 6a-p showed higher α-Glucosidase inhibition activity (90 to 704 µM) in comparison to acarbose as a standard (IC50: 750 µM). 6p, 6m, and 6f exerted the best activity with the IC50 value of 90, 100, and 149 µM respectively. Enzyme kinetic studies showed a competitive mode of inhibition for the most active compound, 6p; molecular docking study revealed the mode of interactions between the most active compounds and enzyme active site. To evaluate the cytotoxicity profile of the synthesized compounds, an MTT assay was done on three different cell lines which showed all 6a-p are safe and nontoxic with IC50 values higher than 750 µM.
Model Slicing on Low-code Platforms
Creators: name: Ibrahimi, Ilirian
name: Moudilos, Dimitris
Publisher: name: Zenodo
Year: 2022

description: Low-code platforms (LCP) use models as the main artifact during the software development process. Typically, the modeling activity concerns both structural and behavioral aspects of the generated application, like the underlying data model (DM), User Interface (UI), and business logic (BL), resulting in a collection of interconnected models. Thus, reusing model fragments across different projects would be a highly beneficial feature for LCPs and their users. This paper presents a model slicing approach for LCP models that combines DM, UI, and BL modeling concerns. A model slice consists of a DM class which serves as an input for the approach, its DM constraint-related classes e.g., base classes, and its related UI entities as well as BL functions. The model slicer operates on separated model repositories which will be queried to find related entities to the DM input class and integrate them automatically into the LCP. We conducted an experimental evaluation with zAppDev models and concluded that 77.78% of the DM classes are cross-connected to any entity among the zAppDev models. Hence all these connected entities can be extracted as model slices and reused automatically.
Sensitivity of coherent anti-Stokes Raman lineshape to time asymmetry of laser pulses

description: We show that coherent anti-Stokes Raman lineshapes do not follow known spectral profiles if the time asymmetry of realistic laser pulses is taken into account. Examples are given for nanosecond and picosecond laser pulses commonly employed in frequency-resolved coherent anti-Stokes Raman scattering. More remarkably, the analysis suggests an effect of line narrowing in comparison to the customary approach, based primarily on the Voigt lineshape.
