description: In the present study, evaluation of the antiproliferative activity of Pachypodium lamerei Drake leaves (family Apocyaceae) against human breast cancer cell lines MDA-MB-231 was done for the total methanolic extract, crude alkaloidal mixture and ursolic acid using the MTT colorimetric assay. The methanolic extract showed the strongest antiproliferative activity followed by ursolic acid and crude alkaloidal fraction with an IC50 equal to 6.2, 14.55 and 56.3 µg/ml respectively compared to oleocanthal. It is the first record for the LC/ESI-MS/MS alkaloidal profiling of the leaves of P. lamerei. Seven alkaloids were tentatively identified according to their fragmentation patterns. Four alkaloids were related to the parent indole class and two alkaloids belong to the quinoline class in addition to one steroidal alkaloid with a pregnan nucleus. Phytochemical investigation of the methanolic extract led to the isolation of three triterpenoidal compounds including ursolic acid, 11,12-didehydroursolic acid lactone and ursolic acid lactone.

Fig. 3
 Cyathopoma diegoense: Fischer-Piette, Blanc & Vukadinovic 1974: 467, figs 2–4 (Cap Diego, northern Madagascar; c. 2× 3 mm).
 A single shell without an operculum, collected on Cabo Delgado, is very similar to the voucher specimen described and illustrated by Emberton (2003: 30–31, fig. 40) from the type locality. The photograph of the shell from Cabo Delgado matches the photograph of the shell from Cap Diego almost exactly when superimposed at 113% magnification. The characteristic sculpture of the spiral cords with the gap on the whorl shoulder (“missing” cord below the suture) and the minute dense axial striation between the spiral cords also can be observed on both shells. Cyathopoma azaniense Verdcourt, 1978 from Kenya is smaller (1.4×2.0 mm) and does not have the characteristic gap between the suture and the first spiral cord on the following whorl.
 The original description of C. diegoense was based on a single adult specimen “environ” (circa) 2 mm high and 3 mm wide. The same size was repeated in comparison with C. artatum Sykes, 1897 on the same page just below the description. However, the figure of the holotype on the same page has a 0.88 h/w ratio, which clearly does not match the proportions stated in the description. Emberton (2003) did not give any explanation for his decision to include the 2.1 mm high and 2.0 mm wide C. duboisi Fischer-Piette, Blanc, Blanc & Salvat, 1993, as well as his 1.9 mm high and 2.9 wide “voucher specimen” in the range of variation of C. diegoense. Thus, the specimen from Cabo Delgado is very likely C. diegoense sensu Emberton, 2003 but the extent of the name diegoense is doubtful.

description: Non-equilibrium ionization effects are important in cosmological hydrodynamical simulations but are computationally expensive. We study the effect of non-equilibrium ionization evolution and UV ionizing background (UVB) generated with different quasar spectral energy distribution (SED) on the derived physical conditions of the intergalactic medium (IGM) at $2\leq z \leq 6$ using our post-processing tool 'Code for Ionization and Temperature Evolution' (CITE). CITE produces results matching well with self-consistent simulations more efficiently. The HeII reionization progresses more rapidly in non-equilibrium model as compared to equilibrium models. The redshift of HeII reionization strongly depends on the quasar SED and occurs earlier for UVB models with flatter quasar SEDs. During this epoch the normalization of temperature-density relation, $T_0(z)$, has a maximum while the slope, $γ(z)$, has a minimum, but occurring at different redshifts. The $T_0$ is higher in non-equilibrium models using UVB obtained with flatter quasar SEDs. While our models produce the observed median HeII effective optical depth evolution and its scatter for equilibrium and non-equilibrium considerations, to explain the observed cumulative distributions we may need to consider fluctuating UVB. For a given UVB model, the redshift dependence of the HI photo-ionization rate derived from the observed HI effective optical depth ($τ_{\rm eff,HI}$) for the equilibrium model is different from that for the non-equilibrium model. This may lead to different requirements on the evolution of ionizing emissivities of sources. We show that, in the absence of strong differential pressure smoothing effects, it is possible to recover the $T_0$ and $γ$ realised in non-equilibrium model from the equilibrium models generated by rescaling photo-heating rates while producing the same $τ_{\rm eff,HI}$.

description: We construct two examples of shareholder networks in which shareholders are connected if they have shares in the same company. We do this for the shareholders in Turkish companies and we compare this against the network formed from the shareholdings in Dutch companies. We analyse the properties of these two networks in terms of the different types of shareholder. We create a suitable randomised version of these networks to enable us to find significant features in our networks. For that we find the roles played by different types of shareholder in these networks, and also show how these roles differ in the two countries we study.
The environmental effects of very large bolide impacts on early Mars explored with a hierarchy of numerical models

description: We use a hierarchy of numerical models (a 3-D Global Climate Model, a 1-D radiative-convective model and a 2-D Mantle Dynamics model) to explore the environmental effects of very large impacts on the atmosphere, surface and interior of early Mars. Using a combination of 1-D and 3-D climate simulations, we show that the environmental effects of the largest impact events recorded on Mars are characterized by: (i) a short impact-induced warm period; (ii) a low amount of hydrological cycling of water; (iii) deluge-style precipitation; and (iv) precipitation patterns that are uncorrelated with the observed regions of valley networks. We show that the impact-induced stable runaway greenhouse state predicted by Segura et al. 2012 is physically inconsistent. We confirm the results of Segura et al. 2008 and Urata & Toon 2013 that water ice clouds can significantly extend the duration of the post-impact warm period, and even for cloud coverage lower than predicted in Ramirez & Kasting 2017. However, the range of cloud microphysical properties for which this scenario works is very narrow. Using 2-D Mantle Dynamics simulations we find that large impacts can raise the near-surface internal heat flux up to several hundreds of mW/m$^2$ (i.e. up to $\sim$ 10 times the ambient flux) for several millions years at the edges of the impact crater. However, such internal heat flux is insufficient to keep the martian surface above the melting point of water. Our numerical results support the prediction of Palumbo & Head 2018 that very large impact-induced rainfall could have caused degradation of craters and formed smooth plains, potentially erasing much of the previously visible morphological surface history. Such hot rainfalls may have also led to the formation of aqueous alteration products on Noachian-aged terrains.

title: In Silico Classification of Industrial Chemicals Associated with Acute Aquatic Toxic Action Utilising Molecular Initiating Events
Creators: name: Sapounidou, M
Publisher: name: Liverpool John Moores University
Year: 2021

description: Chemicals legislation requires the assessment of potential harm to humans and environmental species. There is a move away from testing industrial chemicals in animals to development and use of reliable non-testing methods towards Mode of Action (MOA) determination as an important part of understanding toxicity to aquatic organisms. However, current MOA classification approaches for acute aquatic toxicity endpoints are limited by their chemical and mechanistic domains. This thesis developed an in silico classification scheme for aquatic toxicology to enable grouping according to relevant mechanism of action. Over 6,200 publicly available toxicity data for nearly 5,000 chemicals and 10 aquatic species were collated and curated to form the basis of the analysis. In addition, mechanistic information was compiled and organised in three broad domains: narcotic, non-specific reactive and specific mechanisms of action. Where possible, the aquatic toxicology domains were organised around the Molecular Initiating Events (MIEs) of the relevant Adverse Outcome Pathway(s). Utilising the MIE allowed direct linkage between structural chemistry responsible for toxicity and the adverse outcome. Other considerations included information on the MIE target structure, i.e. the interaction, associated chemistry, taxonomic applicability and the sources and type of data (e.g. in silico, in vivo, in vitro) corresponding to MIE/MIE target of interest. Structural alerts were developed for each mechanism and were documented and evaluated using a MIE-centred set of criteria. Approximately 65 MIE and MIE targets relevant to the aquatic flora and fauna were identified. This knowledge extended greatly the classification scheme for non-specific reactive and specific mechanisms of toxicity beyond the currently applied schemes. The chemical structural criteria for class assignment along with transparency in data source and quality were coded in a workflow. This provides the user with an informed MIE prediction that can be used in the application of the AOPs to better understand chemical classification, predict toxicity and support interspecies risk assessment.

description: Leptogenesis induced by the oscillations of GeV-scale neutrinos provides a minimal and testable explanation of the baryon asymmetry of the Universe. In this work we extend previous studies invoking only two heavy neutrinos to the case of three heavy neutrinos. We find qualitatively new behaviour as a result of lepton number violating oscillations and decays, strong flavour effects in the washout and a resonant enhancement due to matter effects. An approximate global $B - \bar L$ symmetry (representing the difference of baryon and a generalised lepton number) can protect the light neutrino masses from large radiative corrections, while simultaneously providing the ingredients for the resonant enhancement of the lepton asymmetry due to thermal contributions to the heavy neutrino dispersion relations. This mechanism is particularly efficient for large heavy neutrino mixing angles near the current experimental limits, a regime in which leptogenesis is not feasible in the minimal scenario with two heavy neutrinos. In this new parameter regime, low-scale leptogenesis is testable by the LHC and other existing experiments.

description: We present a generic coordinate descent solver for the minimization of a nonsmooth convex objective with structure. The method can deal in particular with problems with linear constraints. The implementation makes use of efficient residual updates and automatically determines which dual variables should be duplicated. A list of basic functional atoms is pre-compiled for efficiency and a modelling language in Python allows the user to combine them at run time. So, the algorithm can be used to solve a large variety of problems including Lasso, sparse multinomial logistic regression, linear and quadratic programs.

description: We overview several recent experimental and numerical observations, which are at odds with the Vortex Glass theory of the freezing of disordered vortex matter. To reinvestigate the issue, we performed numerical simulations of the overdamped London - Langevin model, and use finite size scaling to analyze the data. Upon approaching the transition the initial Vortex Glass type criticality is arrested at some crossover temperature. Below this temperature the timescales continue growing very quickly, consistent with the Vogel-Fulcher form, while the spatial correlation length xi stops exhibiting any observable divergence. We call this mode of freezing the Vortex Molasses scenario.

description: Farmers’ subjectively perceived that administrative transaction costs are of high importance for the uptake of agri-environmental programs with direct effects on the effectiveness and efficiency of these programs and the well-being of farmers. This paper empirically estimates private administrative transaction costs resulting from an uptake of the newly introduced grassland-based milk and meat program in Switzerland, based on farmers’ perceived administrative workload. Using ordered logit models, we analyze how the administrative tasks and farm and farmer characteristics influence the perceived administrative workload. We find that the time spent on monitoring or inspection tasks has no effect. In contrast, an outsourcing of program-related administrative tasks significantly reduces the perceived administrative workload. We also find that a better understanding of agricultural policy regulations significantly reduces the farmers’ perceived administrative workload. We recommend that public administration improve the communication of agricultural policy regulations, rather than investing in the simplification of administrative forms.
The Spectrum of a Fast Shock Breakout from a Stellar Wind

description: The breakout of a fast ($>0.1 c$), yet sub-relativistic shock from a thick stellar wind is expected to produce a pulse of X-rays with a rise time of seconds to hours. Here, we construct a semi-analytic model for the breakout of a sub-relativistic, radiation-mediated shock from a thick stellar wind, and use it to compute the spectrum of the breakout emission. The model incorporates photon escape through the finite optical depth wind, assuming a diffusion approximation and a quasi-steady evolution of the shock structure during the breakout phase. We find that in sufficiently fast shocks, for which the breakout velocity exceeds about $0.1c$, the time-integrated spectrum of the breakout pulse is non-thermal, and the time-resolved temperature is expected to exhibit substantial decrease (roughly by one order of magnitude) during breakout, when the flux is still rising, because of the photon generation by the shock compression associated with the photon escape. We also derive a closure relation between the breakout duration, peak luminosity, and characteristic temperature that can be used to test whether an observed X-ray flare is consistent with being associated with a sub-relativistic shock breakout from a thick stellar wind or not. We also discuss implications of the spectral softening for a possible breakout event XRT 080109/SN 2008D.

Exact Resummations in the Theory of Hydrodynamic Turbulence: I The Ball of Locality and Normal Scaling

Year: 1995
Subjects: subject: Chaotic Dynamics (nlin.CD)

description: This paper is the first in a series of three papers that aim at understanding the scaling behaviour of hydrodynamic turbulence. We present in this paper a perturbative theory for the structure functions and the response functions of the hydrodynamic velocity field in real space and time. Starting from the Navier-Stokes equations (at high Reynolds number Re) we show that the standard perturbative expansions that suffer from infra-red divergences can be exactly resummed using the Belinicher-L'vov transformation. After this exact (partial) resummation it is proven that the resulting perturbation theory is free of divergences, both in large and in small spatial separations. The hydrodynamic response and the correlations have contributions that arise from mediated interactions which take place at some space- time coordinates. It is shown that the main contribution arises when these coordinates lie within a shell of a "ball of locality" that is defined and discussed. We argue that the real space-time formalism developed here offers a clear and intuitive understanding of every diagram in the theory, and of every element in the diagrams. One major consequence of this theory is that none of the familiar perturbative mechanisms may ruin the classical Kolmogorov (K41) scaling solution for the structure functions. Accordingly, corrections to the K41 solutions should be sought in nonperturbative effects. These effects are the subjects of papers II and III in this series, that will propose a mechanism for anomalous scaling in turbulence, which in particular allows multiscaling of the structure functions.

description: Transrelativistic supernovae (SNe), which are likely driven by central engines via jets or winds, have been among candidate sources of ultrahigh-energy cosmic rays (UHECRs). We investigate acceleration and survival of UHECR nuclei in the external reverse shock scenario. With composition models used in Zhang et al. (2018), we calculate spectra of escaping cosmic rays and secondary neutrinos. If their local rate is $\sim1$% of the core-collapse supernova rate, the observed UHECR spectrum and composition can be explained with the total cosmic-ray energy ${\mathcal E}_{\rm cr}\sim10^{51}$ erg. The maximum energy of UHECR nuclei can reach $\sim 10^{20}-{10}^{21}\rm~eV$. The diffuse flux of source neutrinos is predicted to be $\sim 10^{-11} - 10^{-10}~{\rm GeV}~{\rm cm}^{-2}~{\rm s}^{-1}~{\rm sr}^{-1}$ in the 0.1-1 EeV range, satisfying nucleus-survival bounds. The associated cosmogenic neutrino flux is calculated, and shown to be comparable or even higher than the source neutrino flux. These ultrahigh-energy neutrinos can be detected by ultimate detectors such as the Giant Radio Askaryan Neutrino Detector and Probe Of Extreme Multi-Messenger Astrophysics.

description: The localized states within the Heisenberg model of magnetism should be represented by best localized Wannier functions forming a unitary transformation of the Bloch functions of the narrowest partly filled energy bands in the metals. However, as a consequence of degeneracies between the energy bands near the Fermi level, in any metal these Wannier functions cannot be chosen symmetry-adapted to the complete paramagnetic group M^P. Therefore, it is proposed to use Wannier functions with the reduced symmetry of a magnetic subgroup M of M^P [case (a)] or spin dependent Wannier functions [case (b)]. The original Heisenberg model is reinterpreted in order to understand the pronounced symmetry of these Wannier functions. While the original model assumes that there is exactly one electron at each atom, the extended model postulates that in narrow bands there are as many as possible atoms occupied by exactly one electron. However, this state with the highest possible atomiclike character cannot be described within the adiabatic (or Born-Oppenheimer) approximation because in the (true) nonadiabatic system the electrons move on localized orbitals that are still symmetric on the average of time, but not at any moment. The nonadiabatic states have the same symmetry as the adiabatic states and determine the commutation properties of the nonadiabatic Hamiltonian H^n. The nonadiabatic Heisenberg model is a purely group- theoretical model which interprets the commutation properties of H^n that are explicitly given in this paper for the two important cases (a) and (b). There is evidence that the occurrence of these two types of Wannier functions in the band structure of a metal is connected with the occurrence of magnetism and superconductivity, respectively.

description: We present a theoretical analysis of the nonlinear bias and temperature dependence of current-voltage characteristics of a spin-valve device which is formed by connecting a quantum dot to two ferromagnetic electrodes whose magnetic moments orient at an angle $θ$ with respect to each other. The theory is based on nonequilibrium Green's function approach and focused on current perpendicular to plane geometry. Coulomb interaction has been taken into account explicitly at the Hartree level. We derive a formula in closed form for current flowing through the device in general terms of bias and temperature. In the wideband limit we report exact results for the TMR junction nonlinear I-V curve as a function of $θ$. We also report the conductance slope at zero bias as a function of temperature for which experimental results reported an anomalous behavior.

description: We use an analogy between the Yang-Mills theory Hamiltonian and the matrix model description of the closed bosonic membrane theory to calculate the spectrum of glueballs in the large $N_c$ limit. Some features of the Yang-Mills theory vacuum, such as the screening of the topological charge and vacuum topological susceptibility are discussed. We show that the topological susceptibility has different properties depending on whether it is calculated in the weak coupling or strong coupling regimes of the theory. A mechanism of the formation of the pseudoscalar glueball state within pure Yang-Mills theory is proposed and studied.

description: Multiplicity distributions exhibit, after closer inspection, peculiarly enhanced void probability and oscillatory behavior of the modified combinants. We discuss the possible sources of these oscillations and their impact on our understanding of the multiparticle production mechanism. Theoretical understanding of both phenomena within the class of compound distributions is presented.

description: In paper I of this series on fluid turbulence we showed that exact resummations of the perturbative theory of the structure functions of velocity differences result in a finite (order by order) theory. These findings exclude any known perturbative mechanism for anomalous scaling of the velocity structure functions. In this paper we continue to build the theory of turbulence and commence the analysis of nonperturbative effects that form the analytic basis of anomalous scaling. Starting from the Navier-Stokes equations (at high Reynolds number Re) we discuss the simplest examples of the appearance of anomalous exponents in fluid mechanics. These examples are the nonlinear (four-point) Green's function and related quantities. We show that the renormalized perturbation theory for these functions contains ``ladder`` diagrams with (convergent!) logarithmic terms that sum up to anomalous exponents. Using a new sum rule which is derived here we calculate the leading anomalous exponent and show that it is critical in a sense made precise below. This result opens up the possibility of multiscaling of the structure functions with the outer scale of turbulence as the renormalization length. This possibility will be discussed in detail in the concluding paper III of this series.

Figs 6, 56
 Nerita ligata: Müller 1774: 181 (12.7–23.3× 12.7–21.2 mm).
 A common species, recorded from seven stations on Cabo Delgado and inland, with a general distribution from South Africa to Tanzania as well as on Madagascar and Mauritius. Differs from the other three species of Tropidophora in the region by the very weak spiral sculpture on the periphery of the last whorl, with most of the shells having noticeable spiral sculpture only in the umbilical area.

description: We have derived analytic expressions for the amplitudes of correction terms in the critical free energy and inverse correlation length expansions for square, honeycomb, and plane-triangular lattices in strip geometry. We have found that ratio of amplitudes for all of these lattices is universal. We have also obtained similar expansions for the ground state energy and the first energy gap of a critical quantum spin chain and find that the amplitude ratios have the same values.

An Analytical and Numerical Study of Optimal Channel Networks

description: We analyze the Optimal Channel Network model for river networks using both analytical and numerical approaches. This is a lattice model in which a functional describing the dissipated energy is introduced and minimized in order to find the optimal configurations. The fractal character of river networks is reflected in the power law behaviour of various quantities characterising the morphology of the basin. In the context of a finite size scaling Ansatz, the exponents describing the power law behaviour are calculated exactly and show mean field behaviour, except for two limiting values of a parameter characterizing the dissipated energy, for which the system belongs to different universality classes. Two modified versions of the model, incorporating quenched disorder are considered: the first simulates heterogeneities in the local properties of the soil, the second considers the effects of a non-uniform rainfall. In the region of mean field behaviour, the model is shown to be robust to both kinds of perturbations. In the two limiting cases the random rainfall is still irrelevant, whereas the heterogeneity in the soil properties leads to new universality classes. Results of a numerical analysis of the model are reported that confirm and complement the theoretical analysis of the global minimum. The statistics of the local minima are found to more strongly resemble observational data on real rivers.

description: Tropidophora insularis (Pfeiffer, 1852)

 Cyclostoma insulare: Pfeiffer 1852: 64 (“ Isle de France ” – error; 13½ × 17 mm).
 A common species, recorded from seven inland stations, with a general distribution from South Africa to Kenya. “Described from a set in the Cuming collection labelled “ Mauritius,” a locality which Pfeiffer amended to “Natal” in his own working copy of his Monograph” (Connolly 1939: 547). Similar to, and probably a sister species of, T. ligata, with different ecological preferences since they do not co-occur at least in north-eastern Mozambique. Cases of co-occurrence in South Africa should be re-evaluated. Can easily be distinguished from T. ligata by the fairly strong spiral sculpture on the periphery as well as on the rest of the shell, the sculpture being weaker and not as dense and regular as in T. nyasana. It is much larger but otherwise very similar to the following species.

description: Permits are a critical tool for ensuring that infrastructure projects provide the benefits they promise without harming nearby people or the environment. However, the environmental permitting process is complex, often resulting in long review times and increased administrative costs. Identifying ways to hasten permitting processes without compromising environmental rigor is important for enabling efficient and effective infrastructure regulation. This paper evaluates the relationship between permitting duration and characteristics of the projects, applicant organizations, and regulatory regime, using a novel dataset of US Clean Water Act permits. Longer review time was associated with projects proposed by a business (rather than state or federal agencies); using an engineering consultant; requiring some combination of environmental impact analysis, historic preservation, and/or endangered species review; and located in Arizona. Project type, agency workload, and socioeconomic characteristics did not correlate with review time.

description: An extractant forced-circulation three-phase extraction (EC-TPE) device based on extraction-stripping coupling was developed for the preconcentration of Cd2+ in environmental samples. In this three-phase extraction (W1/O↔O/W2) system, Cd2+ in the sample solution (W1) was fully extracted into the stripping phase (W2) by the circular flow of an organic phase (O↔O). The extraction yield (EY) and enrichment factor (EF) reached almost 100% and 100, respectively, under the following operating conditions: 0.1 M HNO3, 2 mL/L di(2-ethylhexyl)phosphoric acid (P204), circulation flow rate of 32 mL/min, circulation time of 45 min and stirring speed of 400 rpm. An extraction yield of more than 98.5% was still achieved after reusing the organic phase eight times. Two theoretical formulas were established for predicting the EY and EF. Thereafter, EC-TPE was applied in the preconcentration of ppb-level Cd2+ for flame atomic absorption spectrophotometer assay with a detection limit of 0.17 μg/L. Addition/recovery tests for Cd2+ were carried out with recoveries exceeding 98%, and three environmental water samples were accurately analyzed. Finally, application of the EC-TPE device was extended to a different extraction system and other metal ions: Zn2+, Cu2+, Ni2+, and Co2+. The EC-TPE device is easily established utilizing common laboratory glassware, and the enrichment operation efficiency can be conveniently improved by using more than one device simultaneously.
