description: With the ever increasing importance of testing drug quality, rapid analytical methods are needed for supervision of Chinese herbal medicines. Near-infrared spectroscopy is one of the most powerful tools in quality assessment of Chinese herbal medicines. In this work, near-infrared spectroscopy was applied to develop a rapid method for quantitative determination of typhaneoside and isorhamnetin-3-O-glucoside in different processed products of Pollen Typhae. A total of 71 batches of samples were collected from different regions in China. After acquisition of near-infrared spectra, different pre-processing methods were compared, and a competitive adaptive reweighted sampling algorithm was used to perform the variable selection. Then a partial least squares regression algorithm was applied to build the quantitative models. The root mean square error of calibration, root mean square error of cross validation, and root mean square error of prediction were 0.0190, 0.0364, and 0.0158%, respectively, for a quantitative model of typhaneoside. The root mean square error of calibration, root mean square error of cross validation, and root mean square error of prediction were 0.0190, 0.0377, and 0.0170%, respectively, for a quantitative model of isorhamnetin-3-O-glucoside. Moreover, the relative prediction deviation values of both quantitative models were larger than 3, indicating good performance of the partial least squares (PLS) models. The results demonstrated that high accuracy prediction of typhaneoside and isorhamnetin-3-O-glucoside could be obtained by near-infrared spectroscopy, to allow an alternative method for quality assessment of different processed products of Pollen Typhae.

description: Excerpts from the report: At the request of food wholesalers in Oakland, the Industrial Development Commission made inquiries of individual wholesale food firms in the city during the fall of 1966 to determine the extent of interest in building a new market that would house all types of food wholesalers. These inquiries showed substantial interest. As a result, Mayor John H. Reading requested the Transportation and Facilities Research Division, Agricultural Research Service, to make a complete study to determine what action should be taken to improve wholesale food distribution in the Oakland area. The study began in the spring of 1967. This study had the following objectives: 1. To determine the adequacy of food marketing facilities in the Oakland area for present and future needs. 2. To develop plans and designs for improved facilities. 3. To consider sites that would be adequate to provide the most efficient means of distributing food supplies to Oakland and the surrounding area. 4. To estimate construction costs, possible operating expenses, and rental requirements. 5. To estimate possible savings and other benefits from improved food-marketing facilities.

description: Synchrotron x-ray scattering measurements of the low-temperature structure of the single-layer manganese oxide La$_{1-x}$Sr$_{1+x}$MnO$_4$, over the doping range $0.33 \le x \le 0.67$, indicate the existence of three distinct regions: a disordered phase ($x < 0.4$), a charge-ordered phase ($x \ge 0.5$), and a mixed phase ($0.4 \le x < 0.5$). For $x>0.5$, the modulation vector associated with the charge order is incommensurate with the lattice and depends linearly on the concentration of $e_g$ electrons. The primary superlattice reflections are strongly suppressed along the modulation direction and the higher harmonics are weak, implying the existence of a largely transverse and nearly sinusoidal structural distortion, consistent with a charge density wave of the $e_g$ electrons.

description: The measured forward slope in elastic and inelastic leptoproduction of vector mesons differ by a substantial amount. In an attempt to describe this phenomenon we construct a two radii model for the target proton, and estimate the effective parameters of the hard Pomeron obtained from a pQCD dipole model with eikonal shadowing corrections (SC). We show that the SC reduce the intercept of the hard Pomeron and generate an effective shrinkage of the forward peak and a diffractive dip at $|t| \approx 1 GeV^2$, which appears to affect the value of the experimentally measured slope.

description: Co-production is a concept which is increasingly popular in the planning field to refer to multi-stakeholder collaboration and partnership with citizens. However, the existing literature suggests that the rapid growth of the concept has resulted in ambiguity about its meaning. Given that the concept has a potential in planning research and practice, the thematic issue aims to present studies that use comparative approaches as a way to sharpen the understanding of co-production. The issue includes one commentary and six articles with empirical evidence from various countries across the world. The editorial provides overarching context and introduces each contribution of the issue.

description: The averaged effective two-body interaction (\textit{AEI}) which can be generated through the lowest order constrained variational (\textit{LOCV}) method for symmetric nuclear matter (\textit{SNM}) with the input \textit{Reid}68 nucleon-nucleon potential, is used as the effective nucleon-nucleon potential in the folding model to describe the heavy-ion (\textit{HI}) elastic scattering cross sections. The elastic scattering cross sections of $^{12}C-^{12}C$ and $^{16}O-^{16}O$ systems are calculated in the above frameworks. The results are compared with the corresponding calculations coming from the fitting procedures with the input finite range \textit{DDM3Y1-Reid} potential and the available experimental data at different incident energies. It is shown that a reasonable description of the elastic $^{12}C-^{12}C$ and $^{16}O-^{16}O$ scattering data at the low and the medium energies can be obtained by using the above \textit{ LOCV AEI}, without any need to define a parameterize density dependent function in the effective nucleon-nucleon potential, which is formally considered in the typical \textit{DDM3Y1-Reid} interactions.

description: We consider a process in which there are two types of particles, A and B, on an infinite one-dimensional lattice. The particles hop to their adjacent sites, like the totally asymmetric exclusion process (ASEP), and have also the following interactions: A+B -> B+B and B+A -> B+B, all occur with equal rate. We study this process by imposing four boundary conditions on ASEP master equation. It is shown that this model is integrable, in the sense that its N-particle S-matrix is factorized into a product of two-particle S-matrices and, more importantly, the two-particle S-matrix satisfy quantum Yang-Baxter equation. Using coordinate Bethe-ansatz, the N-particle wavefunctions and the two-particle conditional probabilities are found exactly. Further, by imposing four reasonable physical conditions on two-species diffusion-reaction processes (where the most important ones are the equality of the reaction rates and the conservation of the number of particles in each reaction), we show that among the 4096 types of the interactions which have these properties and can be modeled by a master equation and an appropriate set of boundary conditions, there are only 28 independent interactions which are integrable. We find all these interactions and also their corresponding wave functions. Some of these may be new solutions of quantum Yang-Baxter equation.

description: The properties of hyperheavy nuclei and the extension of nuclear landscape to hyperheavy nuclei are extensively studied within covariant density functional theory. Axial reflection symmetric and reflection asymmetric relativistic Hartree-Bogoliubov (RHB) calculations are carried out. The role of triaxiality is studied within triaxial RHB and triaxial relativistic mean field + BCS frameworks. With increasing proton number beyond Z~130 the transition from ellipsoidal-like nuclear shapes to toroidal ones takes place. The description of latter shapes requires the basis which is typically significantly larger than the one employed for the description of ellipsoidal-like shapes. Many hyperheavy nuclei with toroidal shapes are expected to be unstable towards multifragmentation. However, three islands of stability of spherical hyperheavy nuclei have been predicted for the first time in Ref. [1]. Proton and neutron densities, charge radii, neutron skins and underlying shell structure of the nuclei located in the centers of these islands have been investigated in detail. Large neutron shell gaps at N=228, 308 and 406 define approximate centers of these islands in neutron number. On the contrary, large proton gap appear only at Z=154 in the (Z~156, N~310) island. As a result, this is the largest island of stability of spherical hyperheavy nuclei found in the calculations. The calculations indicate the stability of the nuclei in these islands with respect of octupole and triaxial distortions. Fission barriers in neutron-rich superheavy nuclei are studied in triaxial RHB framework; the impact of triaxiality on the heights of fission barriers is substantial in some parts of this region. Based on the results obtained in the present work, the extension of nuclear landscape to hyperheavy nuclei is provided.

description: The out-of-equilibrium quantum dynamics of a Bose gas trapped in an asymmetric double well and interacting with a finite-range interaction has been studied in real space by solving the time-dependent many-body Schrödinger equation numerically accurately using the multiconfigurational time-dependent Hartree method for bosons (MCTDHB). We have focused on the weakly interacting limit where the system is essentially condensed. We have examined the impact of the range of the interaction on the dynamics of the system, both at the mean-field and many-body levels. Explicitly, we have studied the maximal and the minimal values of the many-body position variance in each cycle of oscillation, and the overall pace of its growth. We find that the range of the interaction affects the dynamics of the system differently for the right well and the left well. We have also examined the infinite-particle limit and find that even there, the impact of the range of the interaction can only be described by a many-body theory such as MCTDHB.

description: We calculated the effects of structural distortions on the electronic structure of carbon nanotubes. The key modification of the electronic structure brought about by bending a nanotube involves an increased mixing of $σ$ and $π$-states. This mixing leads to an enhanced density-of-states in the valence band near the Fermi energy region. While in a straight tube the states accessible for electrical conduction are essentially pure C($2p_π$)-states, they acquire significant C($2sp_σ$) character upon bending. Bending also leads to a charge polarization of the C-C bonds in the deformed region reminiscent of interface dipole formation. Scattering of conduction electrons at the distorted regions may lead to electron localization at low temperatures.

description: Two-point functions related to the pion weak decay constant f_πare calculated from the generating functional of chiral perturbation theory in the mean-field approximation and the heavy-baryon limit. The aim is to demonstrate that Lorentz invariance is violated in the presence of background matter. This fact manifests itself in the splitting of both f_πand the pion mass into uncorrelated time- and spacelike parts. We emphasize the different in-medium renormalizations of the correlation functions, show the inequivalence between the in-medium values of f_πdeduced from Walecka-type models, on the one hand, and QCD sum rules, on the other hand, and elaborate on the importance for some nuclear physics observables.

description: This chapter deals with various aspects related to the adsorption of long chain-like macromolecules (polymers) onto solid surfaces. Physical aspects of the adsorption mechanism are elaborated mainly at thermodynamical equilibrium. The basic features needed in modeling of this adsorption are discussed. We first discuss the adsorption of a single and long polymer chain to the surface. The surface interaction is modeled by a potential well with a long-ranged attractive tail. A simple mean-field theory description is presented and the concept of polymer "blobs" is used to describe the conformation of the chain at the surface. The thickness of the adsorbed layer depends on several polymer and surface parameters. Fluctuation corrections to mean-field theory are also discussed. We then review adsorption as well as depletion processes in the many-chain case. Profiles, changes in the surface tension and polymer surface excess are calculated within mean-field theory. Corrections due to fluctuations in good solvent are taken into account using scaling concepts. The proximal exponent is introduced in analogy to surface critical phenomena. The interaction between two surfaces with adsorbed polymer layers is discussed, and various cases leading to attractive and repulsive interactions are mentioned. Polyelectrolytes are of practical importance due to their water solubility; we give a short summary of recent progress in this rapidly evolving field. The behavior of grafted polymers, i.e., polymers which are anchored with one end to a solid substrate is also reviewed.

description: We describe in detail a new and highly efficient algorithm for studying site or bond percolation on any lattice. The algorithm can measure an observable quantity in a percolation system for all values of the site or bond occupation probability from zero to one in an amount of time which scales linearly with the size of the system. We demonstrate our algorithm by using it to investigate a number of issues in percolation theory, including the position of the percolation transition for site percolation on the square lattice, the stretched exponential behavior of spanning probabilities away from the critical point, and the size of the giant component for site percolation on random graphs.

Nonlinear Hydrodynamics of Disentangled Flux-Line Liquids

description: In this paper we use non-Gaussian hydrodynamics to study the magnetic response of a flux-line liquid in the mixed state of a type-II superconductor. Both the derivation of our model, which goes beyond conventional Gaussian flux liquid hydrodynamics, and its relationship to other approaches used in the literature are discussed. We focus on the response to a transverse tilting field which is controlled by the tilt modulus, c44, of the flux array. We show that interaction effects can enhance c44 even in infinitely thick clean materials. This enhancement can be interpreted as the appearance of a disentangled flux-liquid fraction. In contrast to earlier work, our theory incorporates the nonlocality of the intervortex interaction in the field direction. This nonlocality is crucial for obtaining a nonvanishing renormalization of the tilt modulus in the thermodynamic limit of thick samples.

description: With unusually slow and high-resolution sweeps of magnetic field, strong, ultra-narrow (width down to $100 {\rm μT}$) resistance peaks are observed in the regime of breakdown of the quantum Hall effect. The peaks are dependent on the directions and even the history of magnetic field sweeps, indicating the involvement of a very slow physical process. Such a process and the sharp peaks are, however, not predicted by existing theories. We also find a clear connection between the resistance peaks and nuclear spin polarization.

description: We consider transmission of system information in a cell-free massive MIMO system, when the transmitting access points do not have any channel state information and the receiving terminal has to estimate the channel based on downlink pilots. We analyze the system performance in terms of outage rate and coverage probability, and use space-time block codes to increase performance. We propose a heuristic method for pilot/data power optimization that can be applied without any channel state information at the access points. We also analyze the problem of grouping the access points, which is needed when the single-antenna access points jointly transmit a space-time block code.

The study adopts three methods: spatial statistics, linear regression and spatial econometrics based on recent UK census and official statistical data (2011–17) of 33 London regions. Spatial analysis shows that cycling networks and bike schemes are concentrated around Inner London. Regions with less cycling infrastructure tend to have a greater proportion of residents of ethnic minorities. The paper highlights the spatial dependence between ethnic inequalities and cycling to work at a regional level in London. There is also evidence of spatial spillovers between neighbouring regions. The paper highlights the need to shift the policy focus from the provision of cycling infrastructure to mobility justice. This means recognizing the needs of distinct groups of cyclists coming from various ethnic minorities. Overall, this paper expands the transportation policies approach by linking it with the concepts of mobilities and regional inequalities. This study of London demonstrates the mechanisms responsible for regional ethnic inequalities in cycling to work that could be relevant in other large urban agglomerations.

Use and Misuse of QCD Sum Rules in Heavy-to-light Transitions: the Decay $B\toρe ν$ Reexamined

description: The existing calculations of the form factors describing the decay $B\toρe ν$ from QCD sum rules have yielded conflicting results at small values of the invariant mass squared of the lepton pair. We demonstrate that the disagreement originates from the failure of the short-distance expansion to describe the $ρ$ meson distribution amplitude in the region where almost the whole momentum is carried by one of the constituents. This limits the applicability of QCD sum rules based on the short-distance expansion of a three-point correlation function to heavy-to-light transitions and calls for an expansion around the light-cone, as realized in the light-cone sum rule approach. We derive and update light-cone sum rules for all the semileptonic form factors, using recent results on the $ρ$ meson distribution amplitudes. The results are presented in detail together with a careful analysis of the uncertainties, including estimates of higher-twist effects, and compared to lattice calculations and recent CLEO measurements. We also derive a set of ``improved'' three-point sum rules, in which some of the problems of the short-distance expansion are avoided and whose results agree to good accuracy with those from light-cone sum rules.

description: Rural social enterprises (RSEs) represent an emerging actor in rural and local socio-economic development. The study of RSEs recognizes the importance of place-based actions for development. Social impacts of RSEs have been touted, particularly in filling roles in the rural context that are underperformed by governments and private actors. However, RSEs’ social impact measurement remains emerging. This review confirms that measurement of RSEs’ social impact, and its attribution to RSEs’ interventions, remain underdeveloped and lacking in both rigour and consistency. Solutions are proposed that contribute to improved methodological approaches applicable to rural regions and appropriate for related interventions confronting spatial disparities in rural development.

description: In line with internationally defined goals of sustainable development, European agricultural policies today have a far-sighted vision for rural areas. Using a case study approach, this paper explores how receptive rural farms in Sicily are to a long-term vision of development. The study focuses on three key factors of a long-term vision, that is, digitalisation, innovation and sustainability, to examine not only whether farms have invested in these areas but also how they perceive their role in the post-pandemic era. Empirical results provide insights into the concentration of farms in the central inland areas of Sicily without any real long-term vision of development. Nevertheless, the analysis also shows that some of them do have a positive attitude to change.
The Effects of Finite Length on the Electronic Structure of Carbon Nanotubes

description: The electronic structure of finite-length armchair carbon nanotubes has been studied using several ab-initio and semi-empirical quantum computational techniques. The additional confinement of the electrons along the tube axis leads to the opening of a band-gap in short armchair tubes. The value of the band-gap decreases with increasing tube length, however, the decrease is not monotonic but shows a well defined oscillation in short tubes. This oscillation can be explained in terms of periodic changes in the bonding characteristics of the HOMO and LUMO orbitals of the tubes. Finite size graphene sheets are also found to have a finite band-gap, but no clear oscillation is observed. As the length of the tube increases the density of states (DOS) spectrum evolves from that characteristic of a zero-dimensional (0-D) system to that characteristic of a delocalized one-dimensional (1-D) system. This transformation appears to be complete already for tubes 5-10 nm long. The chemical stability of the nanotubes, expressed by the binding energy of a carbon atom, increases in a similar manner.

Financial performance analysis of the Islamic and conventional banks during and after the 2008/09 financial crisis: empirical evidence from the kingdom of Saudi Arabia
Creators: name: Alotaibi, Samir Abdullah
Publisher: name: Zenodo
Year: 2024

description: The effects of the 2008/09 financial crisis have been researched widely. A growing body of research claims that the effects of the crisis were limited to USA and other developed countries because of their close business ties. Another body of research, however, claims that almost every part of the world was impacted by the crisis because the world economy is intertwined. While the conflicting findings and claims persist, some of researchers claim that the Islamic Banks (IBs) were not impacted by the crisis because they did not engage in conventional banking practices that exposed the banking industry to the crisis. To bridge the gap, the thesis evaluates the effects of the crisis on the Saudi banking industry by comparing its effects on Saudi Conventional Banks (CBs) with its effects on Saudi Islamic Banks (IBs) between 2006 and 2017. Mixed research method that combined quantitative data with qualitative one was used to evaluate the extent to which the Saudi banking industry was impacted or not impacted by the crisis. The quantitative data, which was in form of secondary data, was obtained online from three IBs and three CBs whereas qualitative data was obtained from 40 research participants (20 participants working in each type of bank). Both ROE and ROA were used to measure banks’ performances. The thesis established that both Saudi IBs and CBs were impacted negatively by the crisis; hence, their ROA and ROE declined during the crisis. Further analysis indicated that the banks were in the processes of recovering from the crisis, but IBs had recovered faster than CBs. The thesis concluded that banks’ unique characteristics did not protect the Saudi IBs from the crisis because the Saudi banking industry was impacted by changes in oil prices and other factors other than the crisis that impacted the banks in developed countries. The thesis recommends that additional measures aimed at protecting both IBs and CBs should be developed to protect the Saudi banking industry from financial crisis in the future. Additionally, it recommends that effective measures aimed at diversifying the Saudi economy should be developed to protect the Saudi banking industry from financial crisis.

description: We assess if a 'donut effect' has occurred in Spain during the COVID-19 pandemic. Our results show a synchronized 30% drop in housing purchases during the national lockdown in 2020, followed by a significant increase from 2021 across the rural-urban continuum, including core cities, suburbs, towns and rural areas, exceeding pre-pandemic levels. We thus found no evidence of a ‘donut effect’ in Spain.

description: Internal migration in Italy has been characterised by deep changes in its composition, because of the growing share of high-skilled migrants (the emigration of which contributes to widening the internal brain drain) and the decreasing proportion of low-skilled migrants. Furthermore, recent interest in the literature in the role played by noneconomic elements in affecting migration decisions has highlighted the importance of a nonpecuniary factor, namely social capital (SC). For these reasons, this paper empirically investigates the role played by SC in interprovincial selective migration, considering migrants according to two education levels using data on 103 Italian provinces (2004–2012). The main findings reveal that provincial SC mainly contributes to reducing the migration flows of low-skilled individuals, albeit while also deterring the emigration of high-skilled individuals. Control variables confirm that better income conditions represent an important determinant of high-skilled migrants most likely because they seek to earn more, while better socioeconomic conditions such as labour market efficiency mostly influence those with a lower level of education.

description: We have used two-fluid dynamics to study the discrepancy between the work of Thouless, Ao and Niu (TAN) and that of Iordanskii. In TAN no transverse force on a vortex due to normal fluid flow was found, whereas the earlier work found a transverse force proportional to normal fluid velocity u and normal fluid density. We have linearized the time-independent two-fluid equations about the exact solution for a vortex, and find three solutions which are important in the region far from the vortex. Uniform superfluid flow gives rise to the usual superfluid Magnus force. Uniform normal fluid flow gives rise to no forces in the linear region, but does not satisfy reasonable boundary conditions at short distances. A logarithmically increasing normal fluid flow gives a viscous force. As in classical hydrodynamics, and as in the early work of Hall and Vinen, this logarithmic increase must be cut off by nonlinear effects at large distances; this gives a viscous force proportional to u/ln(u), and a transverse contribution which goes like u/(ln u)^2, even in the absence of an explicit Iordanskii force. In the limit u goes to zero the TAN result is obtained, but at nonzero u there are important corrections that were not found in TAN. We argue that the Magnus force in a superfluid at nonzero temperature is an example of a topological relation for which finite-size corrections may be large.
