description: A series of 5'-amino-2'-hydroxy-1,3-diaryl-2-propen-1-ones (AC1-AC15) were synthesized by Claisen-Schmidt condensation of 5'-acetamido-2'-hydroxy acetophenone with various substituted aromatic aldehydes. The synthesized compounds were characterized by FTIR, 1H NMR and mass spectrometry and evaluated for their selective cytotoxicity using MTT assay on two cancer cell lines namely breast cancer cell line (MCF-7), colon cancer cell line (HCT-116) and one normal kidney epithelial cell line (Vero). Among the tested compounds, AC-10 showed maximum cytotoxic effect on MCF-7 cell line with IC50 value 74.7 ± 3.5 µM. On HCT-116 cells, AC-13 exhibited maximum cytotoxicity with IC50 value 42.1 ± 4.0 µM followed by AC-14 and AC-10 with IC50 values 62 ± 2.3 µM and 95.4 ± 1.7 µM respectively. All tested compounds were found to be safe on Vero cell line with IC50 value more than 200 µM. Based on their highest efficacy on HCT-116, AC-10, AC-13 and AC-14 were selected for mechanistic study on this cell line by evaluating changes nucleomorphological characteristics using acridine orange-ethidium bromide (AOEB) dual stain and by analyzing cell cycle with flow cytometry using propidium iodide stain. In AOEB staining, all three tested compounds showed significant (p < 0.05) increase in percentage apoptotic nuclei compared to control cells, with highest increase in apoptotic nuclei by AC-13 treatment (31 %). Flow cytometric studies showed cell cycle arrest by AC-10 and AC-14 treatment in G0/G1 phase and by AC-13 in G0/G1 and G2/M phase. The study reflected the potential of AC-10, AC-13 and AC-14 to be the lead molecules for further optimization.

description: We compute both classical and quantum finite-size corrections at leading order in the strong coupling limit for the (dyonic) giant magnon in the Lunin-Maldacena background. Based on the exact S-martix conjectured for the deformed theory, we generalize the Luscher formula to include twisted boundary conditions and show that the results match with those derived both by finite-size classical solutions of the giant magnon and by algebraic curve analysis.

description: We present a detailed auto-consistent study of the nearest blue compact dwarf galaxy NGC 6789 by means of optical and UV archive photometry data and optical long-slit ISIS-WHT spectroscopy observations of the five brightest star-forming knots. The analysis of the spectra in all knots allowed the derivation of ionic chemical abundances of oxygen, nitrogen, sulphur, argon and neon using measures of both the high- and low-excitation electron temperatures, leading to the conclusion that NGC 6789 is chemically homogeneous with low values of the abundance of oxygen in the range 12+log(O/H) = 7.80-7.93, but presenting at the same time higher values of the nitrogen-to-oxygen ratio than expected for its metal regime. We used archival HST/WFPC2 F555W and F814W observations of NGC 6789 to perform a photometric study of the colour-magnitude diagram (CMD) of the resolved stellar populations and derive its star formation history (SFH), which is compatible with the presence of different young and old stellar populations whose metallicities do not necessarily increase with age. We fit the observed optical spectrum in all the five knots using the STARLIGHT code and a combination of single stellar populations following the SFH obtained from the CMD. We compare the resulting stellar masses and the relative fractions of the ionising populations with a non-constrained SFH case. The properties of the younger populations were obtained using CLOUDY photoionisation models, giving similar ages in all the knots in the range 3-6 Myr and the estimation of the dust absorption factor, which correlates with the observed GALEX FUV-NUV colour indices. The total photometric extinction and dust-absorption corrected Hα fluxes were finally used to derive the star formation rates.

description: Surfaces of topological insulators host a new class of states with Dirac dispersion and helical spin texture. Potential quantum computing and spintronic applications using these states require manipulation of their electronic properties at the Dirac energy of their band structure by inducing magnetism or superconductivity through doping and proximity effect. Yet, the response of these states near the Dirac energy in their band structure to various perturbations has remained unexplored. Here we use spectroscopic mapping with the scanning tunneling microscope to study their response to magnetic and non-magnetic bulk dopants in Bi2Te3 and Bi2Se3. Far from the Dirac energy helicity provides remarkable resilience to backscattering even in the presence of ferromagnetism. However, approaching the Dirac point, where the surface states' wavelength diverges bulk doping results in pronounced nanoscale spatial fluctuations of energy, momentum, and helicity. Our results and their connection with similar studies of Dirac electrons in graphene demonstrate that while backscattering and localization are absent for Dirac topological surface states, reducing charge defects is required for both tuning the chemical potential to Dirac energy and achieving high electrical mobility for these novel states.

description: Zur hochrangigen Innenausstattung der St. Annenkirche in Ruppertsgrün gehören acht originale Sand-steinsäulen aus Zwickauer Kohlesandstein. Diese Natursteinarbeiten stehen einerseits für eine erste Verwendung von Renaissance-Elementen im Bereich der ländlichen Architektur in Sachsen, andererseits zeigen sie gravierende Schäden und einen rasanten Schadensfortschritt aufgrund einer anthropogenen Schadbelastung und problematischen raumklimatischen Umweltbedingungen. Durch erste Vorun-tersuchungen konnte belegt werden, dass die zu DDR-Zeiten installierten Außenwandgasheizkörper stark negative Auswirkungen auf die mittlerweile durch die Verbrennungsrückstände schadsalzbelasteten und empfindlichen Natursteinoberflächen der Sandsteinsäulen und deren Kapitelle haben. Durch eine konservierungswissenschaftlich begleitete, restauratorische Überarbeitung der Kohlesandsteinober-flächen können diese stabilisiert werden. Das modellhafte Vorgehen soll auch übertragbare Konservie-rungslösungen für andere Objekte aus dem schwierigen Denkmalgestein hervorbringen. Zusammen mit der Neuinstallation und Neuanordnung der Wärmeabgabeflächen im Kirchenraum kann ein ausgegliche-ner raumklimatischer Zustand im Jahresverlauf gehalten werden, der ein weiteres zyklisches Zerstören der originalen Oberflächen unterbindet.

The deformation of the Schwarzschild surface $r=2M$ produced by the quadrupole moment is shown, and the range of values of this multipole moment is specified, which preserves a regular, closed, continuous and differentiable surface. Some thermodynamic consequences and speculations ensuing from our results are discussed.

description: An intriguing phenomenon in non-equilibrium quantum thermodynamics is the asymmetry of thermal processes. Relaxation to thermal equilibrium is the most important dissipative process, being a key concept for the design of heat engines and refrigerators, contributing to the study of foundational questions of thermodynamics, and being relevant for quantum computing through the process of algorithmic cooling. Despite their importance, the dynamics of these processes are far from being understood. We show that the free relaxation to thermal equilibrium follows intrinsically different paths depending on whether it involves the temperature of the system to increase or to decrease. Our theory is exemplified using the recently developed thermal kinematics based on information geometry theory, utilizing three prototypical examples: a two-level system, the quantum harmonic oscillator, and a trapped quantum Brownian particle, in all cases showing faster heating than cooling under the appropriate conditions. A general understanding is obtained based on the spectral decomposition of the Liouvillian and the spectral gap of reciprocal processes.

description: Using scanning tunneling microscopy and spectroscopy, we have studied the local density of states (LDOS) of graphene over step edges in boron nitride. Long wavelength oscillations in the LDOS are observed with maxima parallel to the step edge. Their wavelength and amplitude are controlled by the energy of the quasiparticles allowing a direct probe of the graphene dispersion relation. We also observe a faster decay of the LDOS oscillations away from the step edge than in conventional metals. This is due to the chiral nature of the Dirac fermions in graphene.

description: In a conformal invariant one-dimensional stochastic model, a certain non-local perturbation takes the system to a new massless phase of a special kind. The ground-state of the system is an adsorptive state. Part of the finite-size scaling spectrum of the evolution Hamiltonian stays unchanged but some levels go exponentially to zero for large lattice sizes becoming degenerate with the ground-state. As a consequence one observes the appearance of quasistationary states which have a relaxation time which grows exponentially with the size of the system. Several initial conditions have singled out a quasistationary state which has in the finite-size scaling limit the same properties as the stationary state of the conformal invariant model.

description: The knowledge of macrofungal diversity associated with Silver Fir forests in Italy is quite scarce. Only a little information is available about macrofungal communities from some Ligurian and Tuscan Silver Fir sites. This study aims to assess the macrofungal diversity of a Silver Fir plantation in Sardinia by the application of a standardized sampling procedure. A total of 606 sporomata were collected and 52 Basidiomycota were identified. The high value of the Shannon Index indicated a considerable level of macrofungal diversity in this plantation. The results were also compared with the diversity indices obtained by a previous 3-years long sampling methodology in the same site. The comparison of the macrofungal diversity values of the Sardinian site with those of the Ligurian Silver Fir forest revealed interesting similarities among natural versus planted coniferous forests.

description: We investigate the initial growth modes and the role of interfacial electrostatic interactions of EuO epitaxy on MgO(001) by reactive molecular beam epitaxy. A TiO2 interfacial layer is employed to produce high quality epitaxial growth of EuO on MgO(001) with a 45° in plane rotation. For comparison, direct deposition of EuO on MgO, without the TiO2 layer shows a much slower time evolution in producing a single crystal film. Conceptual arguments of electrostatic repulsion of like-ions are introduced to explain the increased EuO quality at the interface with the TiO2 layer. It is shown that ultrathin EuO films in the monolayer regime can be produced on the TiO2 surface by substrate-supplied oxidation and that such films have bulk-like magnetic properties.

description: As the rapid progress of the media streaming applications such as video streaming can be classified into two types of streaming, Live video streaming, Video on Demand (VoD). Live video streaming is a service which allows the clients to watch many TV channels over the internet and the clients able to use one operation to perform is to switch the channels. Video on Demand (VoD) is one of the most important applications for the internet of the future and has become an interactive multimedia service which allows the users to start watching the video of their choice at anytime and anywhere, especially after the rapid deployment of the wireless networks and mobile devices. In this paper provide statistical information about the Internet, communications and mobile devices etc. This has led to an increased demand for the development, communication and computational powers of many of the mobile wireless subscribers/mobile devices such as laptops, PDAs, smart phones and notebook. These techniques are utilized to obtain a video on demand service with higher resolution and quality. Another objective in this paper is to see Malaysia ranked as a fully developed country by the year 2020.

description: The double pulsar PSR J0737-3039A/B displays short, 30 s eclipses that arise around conjunction when the radio waves emitted by pulsar A are absorbed as they propagate through the magnetosphere of its companion pulsar B. These eclipses offer a unique opportunity to probe directly the magnetospheric structure and the plasma properties of pulsar B. We have performed a comprehensive analysis of the eclipse phenomenology using multi-frequency radio observations obtained with the Green Bank Telescope. We have characterized the periodic flux modulations previously discovered at 820 MHz by McLaughlin et al., and investigated the radio frequency dependence of the duration and depth of the eclipses. Based on their weak radio frequency evolution, we conclude that the plasma in pulsar B's magnetosphere requires a large multiplicity factor (~ 10^5). We also found that, as expected, flux modulations are present at all radio frequencies in which eclipses can be detected. Their complex behavior is consistent with the confinement of the absorbing plasma in the dipolar magnetic field of pulsar B as suggested by Lyutikov & Thompson and such a geometric connection explains that the observed periodicity is harmonically related to pulsar B's spin frequency. We observe that the eclipses require a sharp transition region beyond which the plasma density drops off abruptly. Such a region defines a plasmasphere which would be well inside the magnetospheric boundary of an undisturbed pulsar. It is also two times smaller than the expected standoff radius calculated using the balance of the wind pressure from pulsar A and the nominally estimated magnetic pressure of pulsar B.

In Italia un primo rinvenimento di questo organismo era stato effettuato nel 2002 in un vivaio piemontese su piante di rododendro; da allora la problematica è riemersa nel 2013, quando numerosi isolati di P. ramorum sono stati trovati associati a piante di Viburnum tinus in alcuni vivai del comprensorio pistoiese, rinomato centro commerciale per il vivaismo a livello internazionale. Numerose indagini di laboratorio sono state effettuate sugli isolati ottenuti dai campioni di tessuto sintomatico. I caratteri micro e macromorfologici accertati su diversi tipi di substrato [Carrot Agar (CA), Corn Meal Agar (CMA), Malt Extract Agar (MEA), Potato Dextrose Agar (PDA) e V8-agar+PARPNH (vedi testo)], il tasso di crescita a diverse temperature (10°, 15°, 20°, 25°, 30°, 32°, e 35° C) ed analisi di tipo molecolare sono stati impiegati per l’identificazione degli isolati. Sono state inoltre condotte prove di inoculazione artificiale sotto corteccia allo scopo di saggiare la virulenza degli isolati reperiti, nel rispetto dei Postulati di Koch. Il Servizio Fitosanitario della Regione Toscana (SFR), immediatamente allertato, ha messo in atto le norme previste per eradicare il problema in campo e contenere ed arginare una eventuale epidemia.

description: We present high-accuracy calculations of the density of states using multicanonical methods for lattice gauge theory with a compact gauge group U(1) on 4^4, 6^4 and 8^4 lattices. We show that the results are consistent with weak and strong coupling expansions. We present methods based on Chebyshev interpolations and Cauchy theorem to find the (Fisher's) zeros of the partition function in the complex beta=1/g^2 plane. The results are consistent with reweighting methods whenever the latter are accurate. We discuss the volume dependence of the imaginary part of the Fisher's zeros, the width and depth of the plaquette distribution at the value of beta where the two peaks have equal height. We discuss strategies to discriminate between first and second order transitions and explore them with data at larger volume but lower statistics. Higher statistics and even larger lattices are necessary to draw strong conclusions regarding the order of the transition.

description: In the present study, we use cross-domain classification using quantum machine learning for quantum advantages to readdress the entanglement versus separability paradigm. The inherent structure of quantum states and its relation to a particular class of quantum states are used to intuitively classify testing states from domains different from training states, called \textit{cross-domain classification}. Using our quantum machine learning algorithm, we demonstrate efficient classifications of two-qubit mixed states into entangled and separable classes. For analyzing the quantumness of correlations, our model adequately classifies Bell diagonal states as zero and non-zero discord states. In addition, we also extend our analysis to evaluate the robustness of our model using random local unitary transformations. Our results demonstrate the potential of the quantum support vector machine for classifying quantum states across the multi-dimensional Hilbert space in comparison to classical support vector machines and neural networks.

description: I tartufi sono funghi ascomiceti appartenenti all’ordine delle Pezizales anche se molti ricercatori considerano “veri tartufi” solo le specie apparteneti al genere Tuber, che comprende le specie di maggiore interesse gastronomico e commerciale quali Tuber melanosporum (tartufo nero pregiato), Tuber magnatum (tartufo bianco pregiato), Tuber aestivum (tartufo estivo o uncinato) e Tuber borchii (tartufo bianchetto). L’elevato valore economico di questi tartufi ha suscitato grande interesse riguardo la loro coltivazione fin dal lontano rinascimento. La nascita della tartuficoltura moderna, tuttavia, risale agli anni 70 in seguito alla scoperta della naura ectomicorrizica del tartufo. Oggi la tartuficoltura è diventata un’importante attività agricola in Europa e nel mondo. In Europa la produzione di T. melanosporum nelle tartufaie coltivate supera addirittura quella delle tartufaie naturali, mentre in Australia, dove il tartufo non cresce naturalmente, si ritiene che la produzione nel 2015 abbia raggiunto le 8 tonnellate. Oltre al tartufo nero pregiato sono coltivati con successo anche T. aestivum e T. borchii, mentre la coltivazione del tartufo bianco pregiato è ancora problematica. Comunque, nonostante i significativi successi raggiunti, alcune tartufaie restano improduttive o producono pochi ascomi. Ciò è conseguenza anche della mancanza di un comune regolamento europeo di certificazione delle piantine tartufigene che garantisca ai tartuficoltori la presenza di un prodotto vivaistico di qualità in tutti i mercati europei. Attualmente le piantine micorrizate sono prodotte esclusivamente mediante inoculazione sporale; l’applicazione dell’inoculazione miceliare potrebbe migliorare le tecniche di coltivazione, rendendo possibile l’impiego di ceppi geneticamente selezionati per le loro caratteristiche ecologiche e/o produttive. Il sequenziamento del genoma del tartufo nero pregiato (T. melanosporum) ha permesso di chiarire alcune fasi del ciclo biologico del tartufo; in particolare, è stato scoperto che è un fungo eterotallico e, perciò, la produzione dei corpi fruttiferi è subordinata dall’incontro di due ceppi appartenenti a “mating type” (tipo sessuale) diverso. Il sequenziamento del genoma di altre specie di tartufo potrà fornirci altre informazioni sulla loro biologia contribuendo a migliorare le tecniche di coltivazione. La genetica potrà inoltre fornirci indicazioni utili a capire il ruolo dei microrganismi associati al tartufo e magari a suggerirci approcci biotecnologici alternativi per il loro utilizzo in tartuficoltura.

description: One of the salient features of graphene is the very high carrier mobility that implies tremendous potential for use in electronic devices. Unfortunately, transport measurements find the expected high mobility only in freely suspended graphen. When supported on a surface, graphene shows a strongly reduced mobility, and an especially severe reduction for temperatures above 200 K. A temperature-dependent mobility reduction could be explained by scattering of carriers with phonons, but this is expected to be weak for pristine, weakly-doped graphene. The mobility reduction has therefore been ascribed to the interaction with confined ripples or substrate phonons. Here we study the temperature-dependent electronic structure of supported graphene by angle-resolved photoemission spectroscopy, a technique that can reveal the origin of the phenomena observed in transport measurements. We show that the electron-phonon coupling for weakly-doped, supported graphene on a metal surface is indeed extremely weak, reaching the lowest value ever reported for any material. However, the temperature-dependent dynamic interaction with the substrate leads to a complex and dramatic change in the carrier type and density that is relevant for transport. Using ab initio molecular dynamics simulations, we show that these changes in the electronic structure are mainly caused by fluctuations in the graphene-substrate distance.

description: Issues of Ge hut array formation and growth at low temperatures on the Ge/Si(001) wetting layer are discussed on the basis of explorations performed by high resolution STM and in-situ RHEED. Data of HRTEM studies of multilayer Ge/Si heterostructures are presented with the focus on low-temperature formation of perfect films. Heteroepitaxial Si p-i-n-diodes with multilayer stacks of Ge/Si(001) quantum dot dense arrays built in intrinsic domains have been investigated and found to exhibit the photo-emf in a wide spectral range from 0.8 to 5 mcm. An effect of wide-band irradiation by infrared light on the photo-emf spectra has been observed. Photo-emf in different spectral ranges has been found to be differently affected by the wide-band irradiation. A significant increase in photo-emf is observed in the fundamental absorption range under the wide-band irradiation. The observed phenomena are explained in terms of positive and neutral charge states of the quantum dot layers and the Coulomb potential of the quantum dot ensemble. By using a coherent source spectrometer, first measurements of terahertz dynamical conductivity (absorptivity) spectra of Ge/Si(001) heterostructures were performed at frequencies 0.3-1.2 THz in the temperature interval from 300 to 5 K. The effective dynamical conductivity of the heterostructures with Ge quantum dots has been discovered to be significantly higher than that of the structure with the same amount of bulk germanium (not organized in an array of quantum dots). The excess conductivity is not observed in the structures with the Ge coverage less than 8 Å. When a Ge/Si(001) sample is cooled down the conductivity decreases. We discuss possible mechanisms that can be responsible for the observed effects.

description: Microbial products containing a mixture of fungi and bacteria (EM Bokashi® 2-fi and EM-5 Sutociu® characterised by plant biostimulant activity), Trichoderma harzianum T22 (biofungicide) and the antagonist fungus Trichoderma sp. TJ40 were tested for efficacy against R. solani disease and for their biostimulant effects on bean plants, in growth chamber experiments, and for their direct effect on the pathogen growth, through in vitro experiments. In growth chamber experiments, EM-5 Sutociu was applied to seed (Sut/Se), substrate (Sut/S) and leaf (Sut/L) many times, EM Bokashi 2-fi to substrare (Bok/S) once and combined with Sut, T22 and TJ40 were applied once to substrate. The pathogen was inoculated to substrate at seeding time (first experiment) or at seedling phase (second experiment). Under our experimental conditions, Bok/S+Sut/S+Sut/L, Sut/S+Sut/L, Sut/Se+Sut/S+Sut/L and T22, in the first experiment, and all treatments, with the exception of Bok/S applied alone in the second experiment, gave significantly disease severity reduction and increase of dry weight and leaf area with respect to the infected control. The TJ40 treatment reduced both disease incidence and disease severity only in the second experiment. In the experiment on the biostimulant effect, T22, Bok/S+Sut/S+Sut/L, Sut/S+Sut/L and Sut/Se+Sut/S+Sut/L showed significantly increases of both dry weight and leaf area. The direct effect of the treatment with T22, TJ40, Bok and Sut on R. solani growth in vitro was studied with two methods, submerged colony (SC) and well diffusion (WD) assays. The pathogen growth was completely inhibited by Trichoderma T22 in both assays, by Trichoderma TJ40 in a range of 80-50 % in SD assay, and 50-30 % in WD assay and slightly inhibited or not inhibited by Bok and Sut.

description: The development of a high-quality and competitive system of vocational education (VET) is an important factor in ensuring national security, which focuses the development of the VET system on the compliance of the scope and areas of training of workers to the needs of the economy and labour market; financing of vocational education with the participation of employers and investing in the training of highly skilled workers. The relevance of the development of vocational education in Ukraine as a factor of national security is further growing in the context of Russia’s military aggression against Ukraine, as it concerns the ability and readiness of graduates of vocational education to serve in the Armed Forces of Ukraine and work in the defence industry. The purpose of the article is to analyse the development of vocational education in terms of strengthening national security, preparing graduates to perform responsibilities for national security and organizing the activities of vocational education institutions on the basis of public-private partnership.

description: We developed a novel method for obtaining the distribution of trapped carriers over their degree of localization in organic transistors, based on the fine analysis of electron spin resonance spectra at low enough temperatures where all carriers are localized. To apply the method to pentacene thin-film transistors, we proved through continuous wave saturation experiments that all carriers are localized at below 50 K. We analyzed the spectra at 20 K and found that the major groups of traps comprise localized states having wave functions spanning around 1.5 and 5 molecules and a continuous distribution of states with spatial extent in the range between 6 and 20 molecules.

description: Die Durchführung der bauphysikalischen Maßnahmen 2003 - 2005 trugen dazu bei, dass der Feuchte- und Salzgehalt im Mauerwerk verringert und das Innenraumklima erheblich verbessert werden konnten, so dass keine Kondensationserscheinungen mehr zu beobachten waren. Durch das langsame Einregulieren der klimatischen Werte konnten die ständig ablaufenden Prozesse des Wasser- und Salztransports, das Auskristallisieren und in Lösung gehen der Salze, verbunden mit der Volumenveränderungen und die daraus resultierende Zermürbung der Substanz beruhigt werden. Ein Bauwerk wie die Barabarakapelle in Thierfeld kann nicht losgelöst als Objekt, sondern muss immer in Zusammenhang mit seiner Umgebung betrachtet werden, denn es reagiert, zwar mit Verzögerung auf jeden äußeren Einfluss. Jegliche Veränderung im peripheren Aussen- wie im Innenbereich sollte im Hinblick auf die weitere Erhaltung der Malereien bedacht werden. Durch regelmäßige Beobachtung, bestenfalls ein Monitoring lassen sich zukünftig Schadensprozesse frühzeitig erkennen und vermeiden.
