description: The adsorption mechanism of temozolomide (TMZ) anticancer drug on functionalised graphene nanosheet with polyethylene glycol (PEG-GNS) is investigated using density functional theory (DFT) calculations and molecular dynamics (MD) simulations. The probability of the formation of ϕâ€“ϕ stacking, hydrogen bond, and the simultaneous effect of these two interactions are investigated. The obtained results from the DFT calculations showed that interaction of TMZ with PEG-GNS is exothermic, and ϕâ€“ϕ stacking interaction between the aromatic rings of TMZ and GNS surface has a vital role in the adsorption process. Also, it is found that the most stable complex is formed in a system where the drug can interact with the graphene surface and PEG agent via ϕâ€“ϕ stacking and hydrogen bond interactions. Furthermore, MD simulations are performed to understand the effects of pH variation on the adsorption process. The obtained results illustrated that the interaction of the drug with the proposed carrier in the neutral system is stronger than protonated systems. The binding free energy value is reduced by decreasing the pH level. It is observed that interactions between TMZ and the nanocarrier are strong inbiological pH conditions. While these interactions become weaker in the acid condition.

description: We present Giant Metrewave Radio Telescope (GMRT) observations of redshifted 21-cm absorption from the $z=0.437$ metal line absorption system towards PKS 1243-072. HI absorption is clearly detected; the absorption profile has a velocity spread of $\sim 20$ km/s. Detection of 21-cm absorption indicates that the absorber has an HI column density large enough to be classified as a damped Lyman-$α$ system. Follow up ground based optical imaging and spectroscopy allow us to identify the absorber with an $L \sim L^\star$ galaxy at an impact parameter of $\sim 9.8$ kpc from the line of sight to the QSO. The absorbing galaxy is unusual in that it has bright emission lines. On the basis of the optical spectrum we are unable to uniquely classify the galaxy since its emission line ratios lie in the transition region between starburst and Seyfert II type spectra.

description: This letter reports on a new method of analysing experimentally gained time series with respect to different types of noise involved, namely, we show that it is possible to differentiate between dynamical and measurement noise. This method does not depend on previous knowledge of model equations. For the complicated case of a chaotic dynamics spoiled at the same time by dynamical and measurement noise, we even show how to extract from data the magnitude of both types of noise. As a further result, we present a new criterion to verify the correct embedding for chaotic dynamics with dynamical noise.

description: Megaselia gregaria (Wood, 1910)
(figures 21, 22)
 Phora gregaria Wood, 1910: 152.
 This species is widely distributed in Europe (Disney, 1991). The recognition of the male was clarified in the key to British species (Disney, 1989). The wings of the Tasmanian specimens are a little darker than those of European specimens. On the face of it this appears to be a European species, presumably introduced by man into Tasmania. However, apart from the very distinctive hypopygium of M. sullivani (see below) the latter species is almost indistinguishable from M. gregaria, even with regard to unusual details such as the scale-like spinules on the labella (figure 22). If this close phenetic resemblance is due to phylogenetic affinity, and if M. sullivani proves to be a Tasmanian endemic, then this would suggest that M. gregaria may have been introduced to Europe from Tasmania rather than the reverse.

description: We present HST/STIS spectra of the Sbc spiral galaxy NGC 4041 which were used to map the velocity field of the gas in its nuclear region. We detect the presence of a compact (r~0.4" ~40 pc), high surface brightness, rotating nuclear disk co-spatial with a nuclear star cluster. The disk is characterized by a rotation curve with a peak to peak amplitude of ~40 km/s and is systematically blueshifted by 10 - 20 km/s with respect to the galaxy systemic velocity. With the standard assumption of constant mass-to-light ratio and with the nuclear disk inclination taken from the outer disk, we find that a dark point mass of 1(-0.7;+0.6) 10^7 Msun is needed to reproduce the observed rotation curve. However the observed blueshift suggests the possibility that the nuclear disk could be dynamically decoupled. Following this line of reasoning we relax the standard assumptions and find that the kinematical data can be accounted for by the stellar mass provided that either the central mass-to-light ratio is increased by a factor of ~2 or that the inclination is allowed to vary. This model results in a 3 sigma upper limit of 6 10^6 Msun on the mass of any nuclear black hole. Overall, our analysis only allows us to set an upper limit of 2 10^7 Msun on the mass of the nuclear black hole. If this upper limit is taken in conjunction with an estimated bulge B magnitude of -17.7 and with a central stellar velocity dispersion of 95 km/s, then these results are not inconsistent with both the MBH-Lsph and the MBH-sigma correlations. Constraints on black hole masses in spiral galaxies of types as late as Sbc are still very scarce and therefore the present result adds an important new datapoint to our understanding of black hole demography.

description: The realm of natural product synthesis constitutes a major part of the interactions between chemistry and the living world. By designing and developing new synthetic routes to natural products, a better insight is gained in terms of new methodology, biological activity and structural novelty. As the field of natural products chemistry advances, ideal syntheses must be strived towards with the investigation of new methodology with high efficiency. Outlined herein are efforts towards the synthesis of four natural products of varying synthetic interests. Although many factors drive interest in their synthesis, they are united by a common goal of pursuing good synthesis. (+-)-Angelmarin (43) has potential a therapeutic agent in the treatment of pancreatic cancer and was synthesised in only 7 linear steps without the use of protecting groups. This was enabled by the recently developed gold(I) catalysed intramolecular hydroarylation chemistry which allowed synthesis of the key coumarin heterocycle in (+-)-columbianetin (44) under mild conditions from the propiolate ester. Investigations were made into the synthesis of the ochrosamines A (117) and B (118), isolated from the endangered rainforest tree Ochrosia moorei, exploring the scope and limitations of novel chemistry such as the vinyl aziridine rearrangement and interrupted Fischer indole synthesis. A number of interesting results were obtained from which much was learnt about the polycyclic system. The hasubanan framework (204) was of synthetic interest as the unnatural enantiomer has potential as a new opiate analogue. The research hoped to expand on recently developed methodology for an intramolecular Alder-ene reaction and its application in a high value context. Lastly, significant progress was made towards the synthesis of bicuculline (228) with the successful synthesis of the advanced intermediate (326) utilising an innovative osmium catalysed intramolecular amidohydroxylation reaction. This carries the possibility of developing an enantioselective synthesis. It is hoped that the natural product can ultimately be synthesised from this late stage material.

description: The applicability of layered graphene oxide (GO) membrane for dehydration of acetic acid using forward osmosis (FO) process is investigated with non-equilibrium molecular dynamics (MD) simulations. The performance of layered GO membrane with different pore offset distance (W) and interlayer distance (H) is investigated. The parameter W is a measure of the size of the constituting GO nanosheets. With the increase in W, the water permeance through layered GO membrane decreases and salt rejection increases. On the other hand, as H increases from 8 Å to 12 Å, the water permeance of the layered GO membrane increases and the corresponding salt rejection decreases. But as H increases beyond 12 Å, the water permeance through layered GO membrane decreases and salt rejection increases. The presence of pinhole defects on the GO nanosheets of layered GO membrane provides shorter route to the water molecules for trans-sheet flow which increases the water permeance of the membranes. With the increase in draw solution concentration the water permeance through the membrane increases but the corresponding variation in the draw solute rejection is much less (<2.0%). With the appropriate tuning of sizes of the GO nanosheets and interlayer spacings, layered GO membrane could be a suitable candidate for dehydration of acetic acid using FO process.

description: Time series both of microwave radiometer brightness temperature measurements at 23.8 and 31.4 GHz and of retrievals of water vapor and liquid water path from these brightness temperatures are evaluated using the detrended fluctuation analysis method. As quantified by the parameter $α$, this method (i) enables identification of the time scales over which noise dominates the time series and (ii) characterizes the temporal range of correlations in the time series. The more common spectral analysis method is also used to assess the data and its results are compared with those from detrended fluctuation analysis method. The assumption that measurements should have certain scaling properties allows the quality of the measurements to be characterized. The additional assumption that the scaling properties of the measurements of an atmospheric quantity are preserved in a useful retrieval provides a means for evaluating the retrieval itself. Applying these two assumptions to microwave radiometer measurements and retrievals demonstrates three points. First, the retrieved water vapor path during cloudy-sky periods can be dominated by noise on shorter than ~30~min time scales ($α$-exponent = 0.1) and exhibits no scaling behavior at longer time scales. However, correlations in the brightness temperatures and liquid water path retrievals are found to be consistent with a power-law behavior for time scales up to 3 hr with an $α$-exponent equal to approximately 0.3, as in other geophysical phenomena. Second, clear-sky, moist atmospheres show the expected scaling for both measurements and retrievals of the water vapor path. Third, during clear-sky, dry atmospheric days, instrument noise from the 31.4 GHz channel compromises the quality of the water vapor path retrieval.

description: Our GMRT HI observations of the ultra diffuse galaxy (UDG) UGC 2162, projected $\sim$ 300 kpc from the centre of the M77 group, reveal it to a have an extended HI disk (R$_{HI}$/R$_{25}$ $\sim$ 3.3) with a moderate rotational velocity (V$_{rot} \sim$ 31 km/s). This V$_{rot}$ is in line with that of dwarf galaxies with similar HI mass. We estimate an M$_{dyn}$ of $\sim$ 1.14 $\times$ 10$^{9}$ M$_\odot$ within the galaxy's R$_{HI}$ $\sim$ 5.2 kpc. Additionally, our estimates of M$_{200}$ for the galaxy from NFW models are in the range of 5.0 to 8.8 $\times$ 10$^{10}$ M$_\odot$. Comparing UGC 2162 to samples of UDGs with HI detections show it to have amongst the smallest R$_e$ with its M$_{HI}$/M$_{\star}$ being distinctly higher and g -- i colour slightly bluer than typical values in those samples. We also compared HI and dark matter (DM) halo properties of UGC 2162 with dwarf galaxies in the LITTLE THINGS sample and find its DM halo mass and profile are within the range expected for a dwarf galaxy. While we were unable to to determine the origin of the galaxy's present day optical form from our study, its normal HI rotation velocity in relation to its HI mass, HI morphology, environment and dwarf mass DM halo ruled out some of the proposed ultra diffuse galaxy formation scenarios for this galaxy.

description: Chiral spin liquids (CSLs) are time-reversal symmetry breaking ground states of frustrated quantum magnets that show no long-range magnetic ordering, but instead exhibit topological order and fractional excitations. Their realization in simple and tractable microscopic models has, however, remained an open challenge for almost two decades until it was realized that Kitaev models on lattices with odd-length loops are natural hosts for such states, even in the absence of a time-reversal symmetry breaking magnetic field. Here we report on the formation of CSLs in a three-dimensional Kitaev model, which differ from their widely studied two-dimensional counterparts, namely, they exhibit a crystalline ordering of the $\mathbb{Z}_2$ gauge fluxes and thereby break some of the underlying lattice symmetries. We study the formation of these unconventional CSLs via extensive quantum Monte Carlo simulations and demonstrate that they are separated from the featureless paramagnet at high temperatures by a single first-order transition at which both time-reversal and lattice symmetries are simultaneously broken. Using variational approaches for the ground state, we explore the effect of varying the Kitaev couplings and find at least five distinct CSL phases, all of which possess crystalline ordering of the $\mathbb{Z}_2$ gauge fluxes. For some of these phases, the complementary itinerant Majorana fermions exhibit gapless band structures with topological features such as Weyl nodes or nodal lines in the bulk and Fermi arc or drumhead surface states.

description: On the basis of the general quantum microscopic theory we study the process of spontaneous decay of an excited atom in a dense and disordered ensemble of point-like impurity atoms embedded into transparent dielectric and located near a charged perfectly conducting surface. We have analyzed the simultaneous influence of the modified spatial structure of field modes near the conductive surface and the electric field on the character of interatomic dipoledipole interaction. This leads to the modification of the transition spectrum of an excited atom inside an ensemble and the spontaneous decay dynamics. We have shown that the electric field changes the cooperative Lamb shift, as well as the character of sub- and superradiant decay.

description: Understanding the properties of the continuum radiation and broad emission lines of active galactic nuclei provide significant information not only to model the radiation mechanism and constrain the geometry and kinematics of the broad-line region (BLR) but also to probe the central engine of the sources. Here we investigate the multifractal behaviour of the H$β$ emission line and the 5100 Å continuum flux light curves of NGC 5548. The aim is to search for multi-scaling signatures in the light curves and check if there is a possible nonlinear relationship between them. To this end, we use a multifractality analysis technique called Multifractal Detrended Moving Average (MFDMA) analysis. We detect multifractal (nonlinear) signatures in the full monitoring and densely sampled period of the H$β$ line and 5100 Å continuum light curves of NGC 5548, possibly indicating the presence of complex and nonlinear interaction in the 5100 Å continuum and H$β$ emission line regions. Moreover, the degree of multifractality of H$β$ line is found to be about twice that of the 5100 Å continuum. The nonlinearity of both emissions could be generated when the broad-line region reprocesses the radiation from the central compact source. Finally, we found that anti-persistent long-range temporal correlation is the main source of the multifractality detected in both light curves.

description: We investigate the pairing property of nuclear matter with Relativistic Hartree-Bogoliubov(RHB) approach. Recently, the RHB approach has been widely applied to nuclear matter and finite nuclei. We have extended the RHB approach to be able to include non-linear coupling terms of mesons. In this paper we apply it to nuclear matter and observe the effect of non-linear terms on pairing gaps.

description: β-Thalassemia (β-thal) is a chronic illness and its complications make the patient less compliant with the treatment protocol. This study aimed to evaluate the effect of a support-training system of peer group on promotion of self-care in β-thal major (β-TM) patients. In this semi-experimental study, 112 β-TM were randomly selected and assigned to the study and control groups. Seven β-TM patients, who were physically, mentally and socially normal, were selected and trained as the peer group. Eight training sessions over 4 months were done by the peer group. The questionnaire with 50 questions was scored using the Likert scale, always with 1 point, sometimes 0.5 point and never 0 points. In the study group, before intervention, the mean score of the patients was 29.84 ± 6.16, which, after intervention, increased significantly to 37.14 ± 4.35, p

description: The polarization of political opinions among members of the U.S. legislative chambers measured by their voting records is greater today than it was thirty years ago. Previous research efforts to find causes of such increase have suggested diverse contributors, like growth of online media, echo chamber effects, media biases, or disinformation propagation. Yet, we lack theoretic tools to understand, quantify, and predict the emergence of high political polarization among voters and their legislators. Here, we analyze millions of roll-call votes cast in the U.S. Congress over the past six decades. Our analysis reveals the critical change of polarization patterns that started at the end of 1980's. In earlier decades, polarization within each Congress tended to decrease with time. In contrast, in the recent decades, the polarization has been likely to grow within each term. To shed light on the reasons for this change, we introduce here a formal model for competitive dynamics to quantify the evolution of polarization patterns in the legislative branch of the U.S. government. Our model represents dynamics of polarization, enabling us to successfully predict the direction of polarization changes in 28 out of 30 U.S. Congresses elected in the past six decades. From the evolution of polarization level as measured by the Rice index, our model extracts a hidden parameter - polarization utility which determines the convergence point of the polarization evolution. The increase in the polarization utility implied by the model strongly correlates with two current trends: growing polarization of voters and increasing influence of election campaign funders. Two largest peaks of the model's polarization utility correlate with significant political or legislative changes happening at the same time.

description: The reliability of any day-to-day material is critically dictated by its properties. One factor which governs the behaviour of a material, under a given condition, is the microstructure. Despite the absence of any phase transformation, a change in the microstructure would significantly alter the properties. Therefore, a substantial understanding on the stability of the microstructure is vital to avert any unexpected catastrophic change in the material properties. In the present work, one such numerical approach called phase-field modelling in employed to analyse the stability of two- and three-dimensional finite structures, which dictate the curvature-driven evolution of the microstructure. A characteristic feature of this numerical approach is the introduction of a scalar variable, called the phase field, in addition to the other thermodynamic variables. While the inclusion of the phase field obviates the need for the interface tracking, which is a strenuous aspect of the other conventional techniques, it replaces the sharp interface with a finite diffuse region. Therefore, before adopting and extending the phase-field technique, it is shown that the model recovers the governing law, i.e, Gibbs-Thomson relation, despite the introduction of the diffuse interface. Subsequently, the numerical treatment is employed to investigate the volume-diffusion governed curvature-induced transformation.
Genetic condition of captive-reared population: a case of Grey partridge (Perdix perdix L.)
Creators: name: Kowalski, Andrzej
Publisher: name: Zenodo

description: A decrease of adaptability and lowering of the fitness is frequently observed in small sized populations due to decline of genetic diversity. Such a state is characteristic of grey partridge (Perdix perdix L.) population analyzed in this work. The population was captured from wildlife and placed in breeding. Next, the birds were relocated to another breeding centers. The structure of population numbering 56 individuals was evaluated through the histone H1.c’ polymorphic locus. It was identified in two-dimensional electrophoresis as composed of two isoforms, H1.c'1 and H1.c'2, having varied net charges. In the analyzed population, the isoforms form homozygous phenotype c’1 and c’2 occurring at a frequency 0.32 and 0.68, respectively. A lack of heterozygous and predomination of homozygous individuals evoke population departure from Hardy-Weinberg equilibrium (p < 0.0001). Population display moderate genetic diversity (δT = 0.45), operation of inbreeding (F = 1) and drift (var(p) = 0.047). Such adverse genetic occurrences, evoked by relocation coupled to transportation of the birds, cause stress limiting acclimatization and adaptability to the new rearing conditions. In a consequence, this leads to decrease of resilience and lowering of the fitness and, therefore, to the overall deterioration of the population status.

 Megaselia impariseta Bridarolli, 1937: 68.
This species has previously been reported from New Zealand and mainland Australia (ACT, NSW). I now report it from Tasmania and Western Australia. It is somewhat more variable in size than has been previously thought.
 Bridarolli (1937) described the previously unknown male of the New Zealand species M. comparabilis Schmitz. I have remounted one of his reported series of four males. It is labelled ‘ Megaselia (Aphiochaeta) comparabilis Schmitz male, Nelson N. Z. 23.V.22 A. Tonnoir cotype’. It has proved to be a female of M. impariseta. Furthermore, it cannot be a cotype of M. comparabilis as the date, locality and collector are listed by Bridarolli and not among the listings for the type series of Schmitz.
 Material
 Thirty-five males, 10 females, Tasmania, Hobart, Battery Point, De Witt Street, garden, 23–31 December 1991, 1–11 January 1992 (R. H. L. Disney —25-4, 7, 34, 39). Male, Western Australia, 33°50∞S, 116°23∞E, 9–10 November 1996 (Cindy Brown, 25-12); female, 34°20∞S, 116°10∞E, 14–15 September 1996 (Cindy Brown, 25-10).
 Natural history
Gravid females had 8–20 nearly mature eggs, the larger specimens having the larger number.

description: The current investigation aims to study the ground-state properties of one of the most interesting isotopic chains in the periodic table, 94-168Sn, from the proton drip line to the neutron drip line by using the covariant density functional theory, which is a modern theoretical tool for the description of nuclear structure phenomena. The physical observables of interest include the binding energy, separation energy, two-neutron shell gap, rms-radii for protons and neutrons, pairing energy and quadrupole deformation. The calculations are performed for a wide range of neutron numbers, starting from the proton-rich side up to the neutron-rich one, by using the density-dependent meson-exchange and the density dependent point-coupling effective interactions. The obtained results are discussed and compared with available experimental data and with the already existing results of relativistic Mean Field (RMF) model with NL3 functional. The shape phase transition for Sn isotopic chain is also investigated. A reasonable agreement is found between our calculated results and the available experimental data.

description: We present a newly measured X-ray temperature function of galaxy clusters using a complete flux-limited sample of 61 clusters. The sample is constructed with the total survey area of 8.14 steradians and the flux limit of 1.99e-11 ergs/s/cm^2 in the 0.1-2.4keV band. X-ray temperatures and fluxes of the sample clusters were accurately measured with ASCA and ROSAT data. The derived temperature function covers an unprecedentedly wide temperature range of 1.4-11keV. By fitting these data with theoretically predicted temperature functions given by the Press-Schechter formalism together with a recent formation approximation and the CDM power spectrum, we obtained tight and individual constraints on Omega_m,0 and sigma_8. We also employed the Formation-Epoch model in which the distribution in the formation epoch of clusters as well as the temperature evolution are taken into account, showing significantly different results. Systematics caused by the uncertainty in the mass-temperature relation are studied and found to be as large as the statistical errors.

description: The heats of formation of haloacetylenes are evaluated using the recent W1 and W2 ab initio computational thermochemistry methods. These calculations involve CCSD and CCSD(T) coupled cluster methods, basis sets of up to spdfgh quality, extrapolations to the one-particle basis set limit, and contributions of inner-shell correlation, scalar relativistic effects, and (where relevant) first-order spin-orbit coupling. The heats of formation determined using W2 theory are: \hof(HCCH) = 54.48 kcal/mol, \hof(HCCF) = 25.15 kcal/mol, \hof(FCCF) = 1.38 kcal/mol, \hof(HCCCl) = 54.83 kcal/mol, \hof(ClCCCl) = 56.21 kcal/mol, and \hof(FCCCl) = 28.47 kcal/mol. Enthalpies of hydrogenation and destabilization energies relative to acetylene were obtained at the W1 level of theory. So doing we find the following destabilization order for acetylenes: FCCF $>$ ClCCF $>$ HCCF $>$ ClCCCl $>$ HCCCl $>$ HCCH. By a combination of W1 theory and isodesmic reactions, we show that the generally accepted heat of formation of 1,2-dichloroethane should be revised to -31.8$\pm$0.6 kcal/mol, in excellent agreement with a very recent critically evaluated review. The performance of compound thermochemistry schemes such as G2, G3, G3X and CBS-QB3 theories has been analyzed.

description: Proximity effects induced in the 2D Dirac material graphene potentially open access to novel and intriguing physical phenomena. Thus far, the coupling between graphene and ferromagnetic insulators has been experimentally established. However, only very little is known about graphene's interaction with antiferromagnetic insulators. Here, we report a low temperature study of the electronic properties of high quality van der Waals heterostructures composed of a single graphene layer proximitized with $α$-RuCl$_3$. The latter is known to become antiferromagnetically ordered below 10 K. Shubnikov de Haas oscillations in the longitudinal resistance together with Hall resistance measurements provide clear evidence for a band realignment that is accompanied by a transfer of electrons originally occupying the graphene's spin degenerate Dirac cones into $α$-RuCl$_3$ band states with in-plane spin polarization. Left behind are holes in two separate Fermi pockets, only the dispersion of one of which is distorted near the Fermi energy due to spin selective hybridization with these spin polarized $α$-RuCl$_3$ band states. This interpretation is supported by our DFT calculations. An unexpected damping of the quantum oscillations as well as a zero field resistance upturn close to the N$é$el temperature of $α$-RuCl$_3$ suggests the onset of additional spin scattering due to spin fluctuations in the $α$-RuCl$_3$.

description: Surface-Enhanced Raman Scattering (SERS) allows for detection and identification of molecular vibrational fingerprints in minute sample quantities. The SERS process can be also exploited for optical manipulation of molecular vibrations. We present a quantum description of Surface-Enhanced Resonant Raman scattering (SERRS), in analogy to hybrid cavity optomechanics, and compare the resonant situation with the off-resonant SERS. Our model predicts the existence of a regime of coherent interaction between electronic and vibrational degrees of freedom of a molecule, mediated by a plasmonic nanocavity. This coherent mechanism can be achieved by parametrically tuning the frequency and intensity of the incident pumping laser and is related to the optomechanical pumping of molecular vibrations. We find that vibrational pumping is able to selectively activate a particular vibrational mode, thus providing a mechanism to control its population and drive plasmon-assisted chemistry.
