description: We have investigated the dynamics of the merging process in the minor merger hypothesis for active galactic nuclei. We find that for a satellite galaxy to be able to merge directly with the nucleus of the host galaxy (for example, to give rise to the compact dust discs which are seen in early type active galaxies) requires the initial orbit of the satellite to be well aimed. For the case of the host galaxy being a disc galaxy, if the initial orbits of the satellites are randomly oriented with respect to the host galaxy, then the orbits of those which reach the host nuclear regions in a reasonable time, are also fairly randomly oriented once they reach the nucleus. We note that this result might be able to provide an explanation of why the jet directions in the nuclei of Seyfert galaxies are apparently unrelated to the plane of the galaxy discs.

description: With acceleration of economic globalization, ecological problem becomes increasingly prominent, and forestry and forest issues become world concerns. Since 1992 United Nations Conference on Environment and Development, sustainable operation of forest becomes a subject of times, and hot issues, such as climate change, value assessment of forest resource, biomass energy of forestry, combating illegal timber and international forest problems, gradually become world concerns. This paper sum up these hot issues, analyzes background and current situations of forestry development, and discusses basic development trends of global forestry.

description: The critical behavior of semi-infinite $d$-dimensional systems with $n$-component order parameter $\bmϕ$ and short-range interactions is investigated at an $m$-axial bulk Lifshitz point whose wave-vector instability is isotropic in an $m$-dimensional subspace of $\mathbb{R}^d$. The associated $m$ modulation axes are presumed to be parallel to the surface, where $0\le m\le d-1$. An appropriate semi-infinite $|\bmϕ|^4$ model representing the corresponding universality classes of surface critical behavior is introduced. It is shown that the usual O(n) symmetric boundary term $\propto \bmϕ^2$ of the Hamiltonian must be supplemented by one of the form $\mathringλ \sum_{α=1}^m(\partial\bmϕ/\partial x_α)^2$ involving a dimensionless (renormalized) coupling constant $λ$. The implied boundary conditions are given, and the general form of the field-theoretic renormalization of the model below the upper critical dimension $d^*(m)=4+{m}/{2}$ is clarified. Fixed points describing the ordinary, special, and extraordinary transitions are identified and shown to be located at a nontrivial value $λ^*$ if $ε\equiv d^*(m)-d>0$. The surface critical exponents of the ordinary transition are determined to second order in $ε$. Extrapolations of these $ε$ expansions yield values of these exponents for $d=3$ in good agreement with recent Monte Carlo results for the case of a uniaxial ($m=1$) Lifshitz point. The scaling dimension of the surface energy density is shown to be given exactly by $d+m (θ-1)$, where $θ=ν_{l4}/ν_{l2}$ is the anisotropy exponent.

description: Assessing the effects of vegetation on water and soil conversation is the key basis for research and management of ecological restoration on water-eroded areas. In this study, the runoff depth, soil loss and corresponding precipitation of five plots planted respectively with Pueraria lobata, Lespedeza bicolor Turcz, Manglietia yuyuanensis Law, Paspalum natatu Fliigge, Paspalum wettsteinii Hackel and one control plot were observed monthly from 2003 to 2010 in Hetian town of Changting County, Fujian Province, a typical water-eroded area in southern China. Then the effects of different vegetation on water/soil conversation (RE/SE) were determined using the ratios of runoff depth/soil loss between vegetated plots to the control plot. Meanwhile, the effect of rainfall on the water and soil loss was also analyzed. The results showed that, both the water and soil conservation effects of Pueraria lobata and Manglietia yuyuanensis Law are better than Lespedeza bicolor Turcz and Paspalum natatu, while Paspalum wettsteinii Hackel are the worst. The differences of effects of water conservation are more significantly than those of soil conversation between five kinds of vegetations. The runoff depth is mainly affected by rainfall, the determination coefficients (R2) of linear regression models between rainfall and runoff depth of all planted plots are all greater than 0.9, whereas the determination coefficients of the linear regression models between rainfall and soil loss vary form 0.3 to 0.8 for different vegetated plots. These results provide a reference for vegetation reconstruction in the current and similar areas.
Motion of the mass centers in a scalar theory of gravitation: the point particle limit

description: We investigate the point-particle limit of the equations of motion valid for a system of extended bodies in a scalar alternative theory of gravitation: the size of one of the bodies being a small parameter xi, we calculate the limit, as xi tends towards 0, of the post-Newtonian (PN) acceleration of this small body. We use the asymptotic scheme of PN approximation, that expands all fields. We find that the PN acceleration A of the small body keeps a structure-dependent part at this limit. In particular, if the only massive body is static and spherical, then A differs from the PN acceleration of a test particle in a Schwarzschild field only by this structure-dependent part. The presence of the latter is due to the fact that the PN metric depends on the first spatial derivatives of the Newtonian potential. Since just the same form of PN metric is valid for the standard form of Schwarzschild's solution, the acceleration of a small body might keep a structure-dependent part at the point limit in general relativity also, depending on the gauge. The magnitude of the structure-dependent acceleration is already challenging on Earth. For the Pioneer spacecrafts, it is likely to discard the current version of the scalar theory. A modified version has been outlined in a quoted reference. Keywords: Weak equivalence principle violation, Asymptotic post-Newtonian scheme

description: Base on 3 m×3 m grid in sloping cornfield with soil auger in Yingwugou Small Watershed of the Dan River Basin, a total of 39 sampling points were collected, and soil water content and nutrient content were measured in different soil depths. Meanwhile, the soil properties of different depth have been analyzed by traditional statistical and geo-statistics approaches. The results showed: the mean value of total nitrogen and soil organic carbon reduced as soil depth increased in general. But soil water content increased as the soil depth increased. The change of total phosphorus with soil depth was not obvious. The total nitrogen, soil water content, soil organic carbon and total phosphorus presented a moderate intensity variation and strong spatial dependence. In these four sampling depths, semi-variance model can simulate the precisions of total nitrogen, soil water content and total phosphorus in the spatial structures of 0 to 10 cm and 10 to 20 cm well. But the spatial structure of soil organic carbon was not good, which could not be simulated with semi-variance model. The analysis with Kriging interpolation showed that, the total nitrogen, soil water content and total phosphorus presented layered distribution in the spatial structures of 0 to 10 cm and 10 to 20 cm; when the spatial distribution changed to 10 to 20 cm from 0 to 10 cm, the average total nitrogen content reduced to 0.310 g/kg from 0.598 g/kg, while the average water content and total phosphorus increased from 12.988% to 15.439% and from 0.229 g/kg to 0.366 g/kg, respectively.

description: Recent surveys of star forming regions have shown that most stars, and probably all massive stars, are born in dense stellar clusters. The mechanism by which a molecular cloud fragments to form several hundred to thousands of individual stars has remained elusive. Here, we use a numerical simulation to follow the fragmentation of a turbulent molecular cloud and the subsequent formation and early evolution of a stellar cluster containing more than 400 stars. We show that the stellar cluster forms through the hierarchical fragmentation of a turbulent molecular cloud. This leads to the formation of many small subclusters which interact and merge to form the final stellar cluster. The hierarchical nature of the cluster formation has serious implications in terms of the properties of the new-born stars. The higher number-density of stars in subclusters, compared to a more uniform distribution arising from a monolithic formation, results in closer and more frequent dynamical interactions. Such close interactions can truncate circumstellar discs, harden existing binaries, and potentially liberate a population of planets. We estimate that at least one-third of all stars, and most massive stars, suffer such disruptive interactions.

description: A moving medium drags light along with it as measured by Fizeau and explained by Einstein's theory of special relativity. Here we show that the same effect can be obtained in a situation where there is no physical motion of the medium. Modulations of both the permittivity and permeability, phased in space and time in the form of travelling waves, are the basis of our model. Space-time metamaterials are represented by effective bianisotropic parameters, which can in turn be mapped to a moving homogeneous medium. Hence these metamaterials mimic a relativistic effect without the need for any actual material motion. We discuss how both the permittivity and permeability need to be modulated in order to achieve these effects, and we present an equivalent transmission line model.

description: We present a theoretical study of the Kadowaki-Woods relation in the orbitally degenerate periodic Anderson model. Based on Fermi liquid theory, we derive the generalized Kadowaki-Woods relation in the strong coupling limit, $Aγ^{-2} \approx 10^{-5} N(N-1)/2$ [μΩcm(mol K/mJ)^2], where $A$ is the coefficient of the $T^2$ term in the resistivity, $γ$ is the $T$-linear specific heat coefficient, and $N$ is the $f$-orbital degeneracy. This result naturally explains the remarkably smaller value of $Aγ^{-2}$ in various orbitally degenerate (mainly Yb-based) heavy Fermion systems, reported by Tsujii et al.: J. Phys. Cond. Mat. 15 (2003) 1993.

description: We study Manneville-Pomeau maps on the unit interval and prove that the set of points whose forward orbits miss an interval with left endpoint 0 is strong winning for Schmidt's game. Strong winning sets are dense, have full Hausdorff dimension, and satisfy a countable intersection property. Similar results were known for certain expanding maps, but these did not address the nonuniformly expanding case. Our analysis is complicated by the presence of infinite distortion and unbounded geometry.

description: Starting from a static spherically symmetric solution of the Einstein's field equations in the second approximation in the perfect fluid scheme, in the exterior of the source, the corresponding metrics depend on a dimensionless parameter $α$ . Taking the Sun for the source, the influence of $α$ on the classical Solar System tests of the general relativity is estimated, the only $α$-dependent one being the Shapiro radar-echo delay experiment. Performing such a test in given conditions within a precision better than $10^{-2}$, it is possible to obtain an experimental value for $α$ . If $α=1$, the Einstein's equations in the weak field approximation take the D'Alembert form, which attests the existence of gravitational waves

description: Outcome regressed on class labels identified by unsupervised clustering is custom in many applications. However, it is common to ignore the misclassification of class labels caused by the learning algorithm, which potentially leads to serious bias of the estimated effect parameters. Due to its generality we suggest to redress the situation by use of the simulation and extrapolation method. Performance is illustrated by simulated data from Gaussian mixture models. Finally, we apply our method to a study which regressed overall survival on class labels derived from unsupervised clustering of gene expression data from bone marrow samples of multiple myeloma patients.

description: An approach is developed for the determination of the current flowing through a nanosize silicon-on-insulator (SOI) metal-oxide-semiconductor field-effect transistors (MOSFET). The quantum mechanical features of the electron transport are extracted from the numerical solution of the quantum Liouville equation in the Wigner function representation. Accounting for electron scattering due to ionized impurities, acoustic phonons and surface roughness at the Si/SiO2 interface, device characteristics are obtained as a function of a channel length. From the Wigner function distributions, the coexistence of the diffusive and the ballistic transport naturally emerges. It is shown that the scattering mechanisms tend to reduce the ballistic component of the transport. The ballistic component increases with decreasing the channel length.

description: We report on the long term monitoring of X-ray dips from the ultracompact low-mass X-ray binary (LMXB) XB 1916-053. Roughly one-month interval observations were carried out with the Rossi X-ray Timing Explorer (RXTE) during 1996, during which the source varied between dim, hard states and more luminous, soft states. The dip spectra and dip lightcurves were compared against both the broadband luminosity and the derived mass accretion rate Mdot. The dips spectra could be fitted by an absorbed blackbody plus cut-off power law non-dip spectral model, with additional absorption ranging from 0 to >100 x 10^22 cm^-2. The amount of additional blackbody absorption was found to vary with the source luminosity. Our results are consistent with an obscuration of the inner disk region by a partially ionized outer disk. The size of the corona, derived from the dip ingress times, was found to be ~10^9 cm. The corona size did not correlate with the coronal temperature, but seemed to increase when \Mdot also increased. We discuss our findings in the context of an evaporated accretion disk corona model and an ADAF-type model.

description: Selecting proper methods of data modelling is crucial in geosciences, as effective data visualization enables better understanding of complex geological phenomena: processes, structure and dynamics. Various approaches of the data analysis by R language include both traditional methods of linear charts and other approaches to data visualization: ternaries, circular and radar charts. Using ternaries for triple correlations between variable can be seen in applied geological analysis which proves it to be important method for data modelling. Visualizing geological variables by ternaries enables to highlight correlation between variables in a triangle, how data are dependent and affected. In this study, several geologic, tectonic and geomorphic variables, such as sediment thickness, tectonic plates, volcanic areas, steepness and depths, were tested using R based modelling in {ggtern} library. Other graphs include radar charts and circular diagrams. Visualizing attributes as a triple component correlation by ternaries gives a better insight to the geological factors. Traditional techniques for visualization of pairwise linear correlations are not sufficient to show triple variations. Ternaries approach identifies data correlations by triple factors. Additional graphical models include circular and Euler-Venn diagrams of quantitative and qualitative geospatial data modelling. The study is supported by 7 R code listings and 9 figures.

description: Since the Randall-Sundrum 1999 papers, braneworlds have been a favourite playground to test string inspired cosmological models. The subject has developped into two main directions : elaborating more complex models in order to strenghten the connection with string theories, and trying to confront them with observations, in particular the Cosmic Microwave Background anisotropies. We review here the latter and see that, even in the simple, "paradigmatic", case of a single expanding brane in a 5D anti-de Sitter bulk, there is still a missing link between the "view from the brane" and the "view from the bulk" which prevents definite predictions.

The structural properties were studied using X-ray diffraction and the recorded patterns indicated that all the films had a preferred orientation along (002) plane and the crystallinity along with the grain size were augmented with annealing temperature. The topographical modification of the films due to heat treatment was probed by atomic force microscopy which revealed that annealing roughened the surface of the film. The optical properties were examined by a UV visible spectrophotometer which exhibited that maximum transmittance reached nearly 90% and it diminished with increasing annealing temperature.

description: APL is a dynamically typed language which deals with arrays whose type,
number of dimensions (rank) and size are not fixed at compile time, but are instead
determined at run time. This makes APL more difficult to compile than static languages
like Pascal or FORTRAN. This thesis describes a prototype implementation
of the core of an APL compiler. The intention thus far has been to demonstrate
techniques for dealing with some of the issues that arise when trying to implement
APL efficiently, rather than to produce a working implementation. The present
program does not do any of the initial lexical processing required, and only compiles
into intermediate code. Object code is never produced. The prototype has
many APL features missing and is undoubtedly full of bugs.

description: We have analyzed optically bright, X-ray faint [OBXF; i.e., log(fX/fR) < -2] sources identified in an 178.9 square arcminute area within the Chandra Deep Field-North (CDF-N) 2 Ms survey. We find 43 OBXF sources in this area, comprising ~15% of the X-ray sources above a 0.5--2 keV flux of 2.3e-17 erg cm^-2 s^-1. We present spectroscopic identifications for 42 of the OBXF sources and optical spectra for 25, including 5 previously unpublished redshifts. Deep optical imaging data (either HST or ground-based) are presented for all the OBXF sources. The OBXF population consists mainly of normal and starburst galaxies detected out to cosmologically significant distances (i.e., to a median redshift of z=0.297 and a full redshift range z=0.06-0.845). This is notable since these distances equate to look-back times of up to ~8 Gyr; we are thus provided with a window on the X-ray emission from galaxies at redshifts much closer to the cosmic star formation peak than was possible prior to Chandra. The X-ray luminosity distribution of OBXF sources extends to higher luminosity than does that of "normal" galaxies indicating that a significant fraction are likely dominated by low-luminosity AGN (LLAGN) or vigorous star formation. By combining the detected X-ray counts, we find the average OBXF X-ray spectrum to be consistent with a Gamma=2.0 power law. The 0.5--2 keV log N-log S for the OBXF galaxies is much steeper (alpha=-1.7) than for the general X-ray source population. Indeed, the number of OBXF sources has doubled between the 1~Ms and 2~Ms survey, rising sharply in numbers at faint fluxes. The extragalactic OBXF sources are found to contribute ~1-2% of the soft extragalactic X-ray background.

description: In this paper we provide an extension for the method of Discrete Lagrangian Descriptors with the purpose of exploring the phase space of unbounded maps. The key idea is to construct a working definition, that builds on the original approach introduced in Lopesino et al. (2015), and which relies on stopping the iteration of initial conditions when their orbits leave a certain region in the plane. This criterion is partly inspired by the classical analysis used in Dynamical Systems Theory to study the dynamics of maps by means of escape time plots. We illustrate the capability of this technique to reveal the geometrical template of stable and unstable invariant manifolds in phase space, and also the intricate structure of chaotic sets and strange attractors, by applying it to unveil the phase space of a well-known discrete time system, the Hénon map.

Abstract
Pitolisant (Wakix®), an orally available, first-in-class antagonist/inverse agonist of the histamine 3 receptor, is approved in the EU (as of March 2016) for the treatment of narcolepsy with or without cataplexy in adults and in the USA (as of August 2019) for the treatment of excessive daytime sleepiness (EDS) in adults with narcolepsy. Pitolisant was demonstrated to have minimal risk of abuse in preclinical and clinical studies, and is the only anti-narcoleptic drug not scheduled as a controlled substance in the USA. The totality of evidence from pivotal and supportive phase III trials suggests that pitolisant administered at up to the recommended maximum dose of 36 mg once daily reduces EDS and cataplexy in adults with narcolepsy
relative to placebo. Noninferiority of pitolisant to modafinil in the management of EDS was not demonstrated. Pitolisant was generally well tolerated in clinical trials. Consistent with its mechanism of action, the most common treatment-emergent adverse events included headache, insomnia and anxiety. With minimal abuse potential and offering the convenience of oral, once-daily administration, pitolisant extends the range of approved treatment options available to adult patients with narcolepsy with or without cataplexy.

description: An electromagnetic field quadrature measurement, performed on one of the modes of the nonlocal single-photon state $a|1,0>-b|0,1>$, collapses it into a superposition of the single-photon and vacuum states in the other mode. We use this effect to implement remote preparation of arbitrary single-mode photonic qubits conditioned on observation of a preselected quadrature value. The quantum efficiency of the prepared qubit can be higher than that of the initial single photon.

description: Gapped periodic quantum systems exhibit an interesting Localization Dichotomy, which emerges when one looks at the localization of the optimally localized Wannier functions associated to the Bloch bands below the gap. As recently proved, either these Wannier functions are exponentially localized, as it happens whenever the Hamiltonian operator is time-reversal symmetric, or they are delocalized in the sense that the expectation value of $|\mathbf{x}|^2$ diverges. Intermediate regimes are forbidden. Following the lesson of our Maestro, to whom this contribution is gratefully dedicated, we find useful to explain this subtle mathematical phenomenon in the simplest possible model, namely the discrete model proposed by Haldane (Phys. Rev. Lett. 61, 2017 (1988)). We include a pedagogical introduction to the model and we explain its Localization Dichotomy by explicit analytical arguments. We then introduce the reader to the more general, model-independent version of the dichotomy proved in (Commun. Math. Phys. 359, 61-100 (2018)), and finally we announce further generalizations to non-periodic models.

description: We have detected a spatially resolved supernova remnant (SNR) in the center of the Andromeda Galaxy, in radio, X-ray, and optical wavelengths. These observations provide the highest spatial resolution imaging of a radio/X-ray/optical SNR in that galaxy to date. The multi-wavelength morphology, radio spectral index, X-ray colors, and narrow-band optical imaging are consistent with a shell-type SNR. A second SNR is also seen resolved in both radio and X-ray. By comparing the morphological sturcture of the SNRs in different wavelengths and with that in our own Galaxy, we can study the shock morphologies of SNRs in the Andromeda Galaxy. The proximity of the SNRs to the core suggests high interstellar medium density in the vicinity of the SNRs in the center of the Andromeda Galaxy.

description: Partial nephrectomy is the optimal surgery for early-stage renal tumours. Selective clamping (only clamping those arteries that perfuse maximal tumour and minimal healthy tissue) lowers the risk of excessive bleeding during tumour resection, while safeguarding the remaining healthy tissue’s renal function. To clamp successfully, insight in the patient-specific perfusion zones is necessary, which cannot be provided by CT-scans. Therefore, we propose a 3D renal perfusion model, which we validated in a retrospective study (De Backer, Vermijs et al. 2023). Twenty-five patients were included. Their four-phase CT-scan was segmented in Mimics (Materialise, Belgium) to create a 3D model. The arteries were simplified to a centerline using VMTK (vmtk.org) to label the branches. The labelled centerline points served as seeds in a Python-based region growing algorithm, executed in a voxelized bounding box around parenchyma and tumour. This resulted in a 3D renal perfusion model for each patient. To validate this, the clamped selective arteries were detected on the surgical video. Their perfusion zones, which were made visible during surgery using indo-cyanine green under near-infrared lighting, were compared to the calculated perfusion model using two metrics. The first metric, the total overlap of the perfusion zone contours, was scored by six independent urologists. This resulted in an average score of 4.28 out of 5 (median: 5; range: 2-5: interquartile range: 4-5). The second metric, focusing on the perfusion of the tumour, was evaluated using a scoring grid and resulted in an average score of 4.14 out of 5 (median: 5; range: 1-5; interquartile range: 3.5-5). The high scores for both metrics show that the proposed algorithm is robust. A limitation of this study is that indo-cyanine green only reveals perfusion at surface level. However, the results are promising and show that the perfusion model can assist in preoperative planning.
Integrating Task and Data Parallelism

Subjects: Computer Science

description: Many models of concurrency and concurrent programming have been proposed; most can
be categorized as either task-parallel (based on functional decomposition) or data-parallel
(based on data decomposition). Task-parallel models are most effective for expressing irregular
computations; data-parallel models are most effective for expressing regular computations.
Some computations, however, exhibit both regular and irregular aspects. For
such computations, a better programming model is one that integrates task and data parallelism.
This report describes one model of integrating task and data parallelism, some
problem classes for which it is effective, and a prototype implementation.

description: As many US countries have adopted its methodology, the ERM Architecture, has become the global standard for ERM. The institutions of higher education (HEIs) develop sophisticated strategies for risk management (Aiko 2015). In its case study, the researcher Aiko KAGEYAMA had claimed that it takes years and needs cross-functional groups and control for implementation of the ERM structure or program. Numerous HEIs in the USA have adopted the ERM, with different methodologies and processes that should serve as a potential focus for research in various countries and cultures. The analysis examines the integration and adaptation in every organization of ERMs with specific tasks and contexts in HEIs. The threats would impact the university's ability to operate as a corporation either positively or negatively in an institutional sense and to achieve its strategic goals. The critical threats in academic institutions are identified and determined by this report (SV Toma, IV Alexa, DA Sarpe, 2014). The significant risk of loss is revenue structure and expenditure based on various students, budgetary allocation, tuition fees, administrative fees, tax-and ex-budget income relationships, flows of students and incomes, and spending of scientists.

Orifice coefficients for an asymmetrical flow into a slot

Subjects: subject: Mechanical Engineering
subject: FOS: Mechanical engineering

description: The purpose of this investigation is to determine what percentage, if any, of a freestream velocity head is recovered by the flow through a slot. In this experiment, fluid is drawn through a slot placed perpendicular to a passing flow. This project addresses orifice coefficients, a classic subject, which has been thoroughly investigated. However, unlike most of the previous experiments measuring orifice or resistance coefficients, the flow approaching the orifice, or slot in this case, is not symmetrical. Mainstream flow rate and orifice flows are explored systematically over a fairly wide range. The primary motivation is to gain a better understanding of the fluid dynamics associated with small orifices in the presence of a passing flow.

Structure of the center manifold of the L1 and L2 collinear libration points in the restricted three-body problem

description: We present a global analysis of the center manifold of the collinear points in the circular restricted three-body problem. The phase-space structure is provided by a family of resonant 2-DOF Hamiltonian normal forms. The near 1:1 commensurability leads to the construction of a detuned Birkhoff-Gustavson normal form. The bifurcation sequences of the main orbit families are investigated by a geometric theory based on the reduction of the symmetries of the normal form, invariant under spatial mirror symmetries and time reversion. This global picture applies to any values of the mass parameter.
