description: Current status of the mortgage financing of forest rights is introduced. Significance of the development of mortgage financing of rural forest rights is analyzed, indicating that the mortgage financing of rural forest rights is an inevitable trend of rural reform development, Mortgage financing of forest rights in rural China is an effective vector for the farmers' income increase project with financial support, explores the great potential of forest resources, promotes the coordinated development of forestry and financial services. Major obstacles for the mortgage financing of forest rights at present is pointed out. which are the high assessment fees. the complex mortgage valuation. the unsound element market of forestry, and the lack of risk protection mechanism. Countermeasures for the development of mortgage financing of forest rights is out forward. For instance, both government and Forestry Bureau should strengthen the circulation services, establish smooth evaluation mechanism, establish companies for rural assets platform, increase the interest subsidies for forest right mortgage and the risk compensation, strengthen the team construction and improve the service system.

description: This article sheds light on the entanglements of difficult heritage and digital media through an ethnographic analysis of digital photography and social media practices at the Memorial to the Murdered Jews of Europe in Berlin. After a discussion of the project ‘Yolocaust’, through which an artist publicly shamed the ‘selfie culture’ at the memorial, the article argues that the sweeping condemnation of digital self-representations in the context of Holocaust remembrance remains simplistic. Instead, many visitors explore and enact potential emotional relationships to the pasts that sites of difficult heritage represent through digital self-representations. This observation raises critical questions about the role of digital media in current transformations of touristic memory cultures.

description: We investigate equilibrium configurations of uniformly rotating neutron stars in $R^2$ gravity with axion scalar field for GM1 equation of state (EoS) for nuclear matter. The mass-radius diagram, mass-central energy density are presented for some frequencies in comparison with static stars. We also compute equatorial and polar radii and moment of inertia for stars. For axion field $ϕ$ the coupling in the form $\sim R^2ϕ$ is assumed. Several interesting results follow from our consideration. Maximal possible star mass with given EoS increases due to the contribution of coupling term. We discovered the possibility to increase maximal frequency of the rotation in comparison with General Relativity. As a consequence the lower bound on mass of the fast rotating stars decreases. For frequency $f=700$ Hz neutron stars with masses $\sim M_\odot$ can exist for some choice of parameters (in General Relativity for same EoS this limit is around $1.2 M_{\odot}$). Another feature of our solutions is relatively small increase of stars radii for high frequencies in comparison with static case. Thus, eventually the new class of neutron stars in $R^2$ gravity with axions is discovered namely fast rotating compact stars with intermediate masses.

description: Considering the complexity of vegetables price forecast, the prediction model of vegetables price was set up by applying the neural network based on genetic algorithm by using the characteristics of genetic algorithm and neural work. Taking mushrooms as an example, the parameters of the model are analyzed through experiment. In the end, the results of genetic algorithm and BP neural network are compared. The results show that the absolute error of prediction data is in the scale of 10%; in the scope that the absolute error in the prediction data is in the scope of 20% and 15%. The accuracy of genetic algorithm based on neutral network is higher than the BP neutral network model, especially the absolute error of prediction data is within the scope of 20%. The accuracy of genetic algorithm based on neural network is obviously good than BP neural network model, which represents the favorable generalization capability of the model.

description: MDM2 and MDMX are potential targets for p53-dependent cancer therapy. Peptides are key in cellular immunology and oncology, and cyclic peptides generally have higher half-life than their linear counterparts. However, prediction of cyclic peptide–protein binding is challenging with normal molecular simulation approaches because of high peptide flexibility. Here, we used global peptide docking, normal molecular dynamics, Gaussian accelerated molecular dynamics (GaMD), two-dimensional (2D) potential of mean force (PMF) profiles, and solvated interaction energy (SIE) techniques to investigate the interactions of MDM2/MDMX with three N-to-C-terminal cyclic peptide–based inhibitors. We determined the possible cyclic peptide–MDM2/MDMX complex structures via 2D PMF profiles and SIE calculations. Our findings increase the accuracy of peptide–protein structural prediction, which may facilitate cyclic peptide drug design. Advancements in the computational methods and computing power may further aid in addressing the challenges in cyclic peptide drug design.

description: Transfer entropy (TE) captures the directed relationships between two variables. Partial transfer entropy (PTE) accounts for the presence of all confounding variables of a multivariate system and infers only about direct causality. However, the computation of PTE involves high dimensional distributions and thus may not be robust in case of many variables. In this work, different variants of PTE are introduced, by building a reduced number of confounding variables based on different scenarios in terms of their interrelationships with the driving or response variable. Connectivity-based PTE variants and utilizing the random forests (RF) methodology are evaluated on synthetic time series. The empirical findings indicate the superiority of the suggested variants over TE and PTE, especially in case of high dimensional systems.

description: Inclusive growth is a resurgent concern for policymakers, raising questions about what economic development is for and the outcomes to be prioritized. This paper contributes to the literature by examining the opportunities and challenges emerging from attempts to operationalize inclusive growth in four regional contexts in Scotland. We show that applying inclusive growth ultimately rests on complex factors, from local leadership and autonomy through to the guidance and analytical support provided by other orders of government. Implementing inclusive growth hinges, indeed, on securing incremental, practical change that is attentive to varied regional challenges.

description: Perception is shaped by actions, which determine the allocation of selective attention across the visual field. Here, we review evidence that maintenance in visual working memory is similarly influenced by actions (eye or hand movements), planned and executed well after encoding: Representations that are relevant for an upcoming action – because they spatially correspond to the action goal or because they are defined along action-related feature dimensions – are automatically prioritised over action-irrelevant representations and held in a stable state. We summarise what is known about specific characteristics and mechanisms of selection-for-action in working memory, such as its temporal dynamics and spatial specificity, and delineate open questions. This newly-burgeoning area of research promotes a more functional perspective on visual working memory that emphasizes its role in action control.

description: The human phosphoserine phosphatase (hPSP) catalyses the last step in the biosynthesis of L-serine. It involves conformational changes of the enzyme lid once the substrate, phosphoserine (PSer), is bound in the active site. Here, Elastic Network Model (ENM) is applied to the crystal structure of hPSP to probe the transition between open and closed conformations of hPSP. Molecular Dynamics (MD) simulations are carried out on several PSer-hPSP systems to characterise the intermolecular interactions and their effect on the dynamics of the enzyme lid. Systems involving either Ca++ or Mg++ are considered. The first ENM normal mode shows that an open-closed transition can be explained from a simple description of the enzyme in terms of harmonic potentials. Principal Component Analyses applied to the MD trajectories also highlight a trend for a closing/opening motion. Different PSer orientations inside the enzyme cavity are identified, i.e. either the carboxylate, the phosphate group of PSer, or both, are oriented towards the cation. The interaction patterns are analysed in terms of hydrogen bonds, electrostatics, and bond critical points of the electron density distributions. The latter approach yields a global description of the bonding intermolecular interactions. The PSer orientation determines the content of the cation coordination shell and the mobility of the substrate, while Lys158 and Thr182, involved in the reaction mechanism, are always in interaction with the substrate. Closed enzyme conformations involve Met52-Gln204, Arg49-Glu29, and Arg50-Glu29 interactions. Met52, as well as Arg49 and Arg50, also stabilize PSer inside the cavity. Communicated by Ramaswamy H.

description: This paper identifies the migration policies that emerge when both the sending country and the receiving country wield power to set migration quotas, when controlling migration is costly, and when the decision how much human capital to acquire depends, among other things, on the migration policies. The paper analyzes the endogenous formation of bilateral agreements in the shape of transfers to support migration controls, and in the shape of joint arrangements regarding the migration policy and the cost-sharing of its implementation. The paper shows that in equilibrium both the sending country and the receiving country can participate in setting the migration policy, that bilateral agreements can arise as a welfare-improving mechanism, and that the sending country can gain from migration even when it does not set its preferred policy.

description: The Compressed Baryonic Matter (CBM) experiment will investigate high-energy heavy-ion collisions at the international Facility for Antiproton and Ion Research (FAIR), which is under construction in Darmstadt, Germany. The CBM research program is focused on the exploration of QCD matter at neutron star core densities, such as study of the equation-of-state and the search for phase transitions. Key experimental observables include (multi-) strange (anti-) particles, electron-positron pairs and dimuons, particle correlations and fluctuations, and hyper-nuclei. In order to measure these diagnostic probes multi-differentially with unprecedented precision, the CBM detector and data acquisition systems are designed to run at reaction rates up to 10 MHz. This requires the development of fast and radiation hard detectors and readout electronics for track reconstruction, electron and muon identification, time-of-flight determination, and event characterization. The data are read-out by ultra-fast, radiation-tolerant, and free-streaming front-end electronics, and then transferred via radiation-hard data aggregation units and high-speed optical connections to a high-performance computing center. A fast and highly parallelized software will perform online track reconstruction, particle identification, and event analysis. The components of the CBM experimental setup will be discussed, and results of physics performance studies will be presented.

Polarimetry and multi-color photometry using all-sky cameras in Lovozero (Murmansk Region, Russia, 68.0 deg N, 35.1 deg E) together with a new method of cloud field separation against the twilight background allowed for finding the light scattering characteristics related to the particle size distribution of polar stratospheric clouds. The results are compared with lidar and balloon experiments. The conditions of the appearance of visually bright polar stratospheric clouds of type I are discussed.

description: The overexpression of interleukin-13 (IL-13) leads to autoimmune and inflammatory diseases. These adverse responses can be neutralized by using lebrikizumab as a therapeutic monoclonal antibody (mAb). Herein, we have attempted to modulate the lebrikizumab mAb to enhance its binding affinity towards IL-13. The interface residues of the lebrikizumab-IL-13 complex were determined by the PyMOL and verified by the artificial neural network-based B-cell epitope prediction server (ABCpred server) and the Paratome web server. The Cologne University Protein Stability Analysis Tool (CUPSAT) web server based mutational approach was used to identify the stable and favorable interface mutations in the lebrikizumab. Only 40 mutations were selected to generate a single mutant library, and their binding affinity for IL-13 was analyzed by using the Z-Dock server. Based on high Z-score, mutants having a better affinity with IL-13 were selected to create a multi-mutant library. The multi-mutant library was again subjected to the Z-Dock server, and their binding affinity was determined. The highest-scoring ten mAb mutants were validated by using PatchDock and ClusPro servers. The best two potential mAb mutants were identified and subjected to molecular dynamics (MD) simulations to ensure its structural stability at the microscopic level. The changes in the different bonds as the effect of mutation were assessed by LigPlot + v2.1. The AllerTOP and ToxinPred web servers were used to analyze the non-allergic and nontoxic nature of the selected mutants. Therefore, these redesigned mAb could be used for potential treatment against IL-13 associated diseased conditions.

description: Depuis quelques années, la qualité nutritionnelle de l'alimentation est (re)devenue une préoccupation importante des politiques de santé publique. Pour les décideurs, il s'agit de trouver les meilleurs moyens d'agir sur les choix alimentaires de la population. Ce document montre comment les économistes analysent les politiques de taxation et d'information visant à modifier la qualité nutritionnelle des choix alimentaires des consommateurs. Prenant l'exemple de l'obésité, il souligne que la principale source d'inefficience de politiques non ciblées (taxation ou diffusion générale d'information) est l'existence d'hétérogénéités individuelles observables ou non. Des politiques d'information ciblées sur les populations à risque, ou des politiques de taxation ou de subvention des produits sur les lieux de restauration collective pourraient s'avérer plus efficaces.

description: Contrairement à ce qui était attendu, l'ajustement structurel du secteur agricole polonais, observé pendant la phase de transition qui a suivi la chute du régime socialiste, a été de faible ampleur : en particulier, les exploitations de petite taille (7 hectares en moyenne) se sont maintenues. Cette recherche montre que les petites exploitations sont restées majoritaires en Pologne, non pas parce qu'elles sont le type d'exploitations le plus efficace techniquement, mais parce que la restructuration du secteur a été contrainte par un fonctionnement imparfait des marchés des facteurs de production. L'accès limité au crédit et le système de retraite agricole peuvent en particulier expliquer cette faible restructuration.

Its position was previously measured in a molecule-dissociation experiment for which we, here, discuss systematic shifts.

description: A l'instar d'autres forêts méditerranéennes, la forêt corse est associée à la transhumance et au pastoralisme, deux activités qui ont beaucoup décliné. Les ventes de bois sont trop faibles pour compenser les dépenses de gestion, et les perspectives de développement de production marchande (cueillette de baies, champignons, plantes aromatiques) ou de la chasse sont restreintes. La justification sociale des dépenses publiques en faveur de la forêt corse doit donc être recherchée dans les services non-marchands liés aux loisirs et à la protection de l'environnement. Mais peut-on concilier la protection de la forêt et l'accueil du public ? Peut-on proposer des aménagements qui respectent la biodiversité ? Peut-on faire face à la pression touristique tout en préservant les équilibres naturels ? Doit-on accueillir tout le monde ou limiter l'accès ? Questions difficiles auxquelles sont confrontés les élus, les pouvoirs publics et les citoyens. Les travaux réalisés à Bonifatu apportent des données factuelles et des éléments de réflexion pour définir une stratégie de développement durable en zone de montagne méditerranéenne.

It acts in commonplace circumstances and should be therefore compatible with the mathematical frame of quantum field theory and the standard model. These conditions lead to an essentially unique model for reduction. Consistency with renormalization and time-reversal violation suggest however a primary action in the vicinity of Planck's length. The inclusion of quantum gravity and the uniqueness of space-time point moreover to generalized quantum theory, first proposed by Gell-Mann and Hartle, as a convenient framework for developing this model into a more complete theory.

description: The data-driven discovery of partial differential equations (PDEs) consistent with spatiotemporal data is experiencing a rebirth in machine learning research. Training deep neural networks to learn such data-driven partial differential operators requires extensive spatiotemporal data. For learning coarse-scale PDEs from computational fine-scale simulation data, the training data collection process can be prohibitively expensive. We propose to transformatively facilitate this training data collection process by linking machine learning (here, neural networks) with modern multiscale scientific computation (here, equation-free numerics). These equation-free techniques operate over sparse collections of small, appropriately coupled, space-time subdomains ("patches"), parsimoniously producing the required macro-scale training data. Our illustrative example involves the discovery of effective homogenized equations in one and two dimensions, for problems with fine-scale material property variations. The approach holds promise towards making the discovery of accurate, macro-scale effective materials PDE models possible by efficiently summarizing the physics embodied in "the best" fine-scale simulation models available.

description: By observing trends in the folding kinetics of experimental 2-state proteins at their transition midpoints, and by observing trends in the barrier heights of numerous simulations of coarse grained, C-alpha model, Go proteins, we show that folding rates correlate with the degree of heterogeneity in the formation of native contacts. Statistically significant correlations are observed between folding rates and measures of heterogeneity inherent in the native topology, as well as between rates and the variance in the distribution of either experimentally measured or simulated phi-values.

description: Herein, molecular modeling techniques were used with the main goal to obtain candidates from a drug database as potential targets to be used against SARS-CoV-2. This novel coronavirus, responsible by the COVID-19 outbreak since the end of 2019, became a challenge since there is not vaccine for this disease. The first step in this investigation was to solvate the isolated S-protein in water for molecular dynamics (MD) simulation, being observed a transition from “up” to “down” conformation of receptor-binding domain (RBD) of the S-protein with angle of 54.3 and 43.0 degrees, respectively. The RBD region was more exposed to the solvent and to the possible drugs due to its enhanced surface area. From the equilibrated MD structure, virtual screening by docking calculations were performed using a library contained 9091 FDA approved drugs. Among them, 24 best-scored ligands (14 traditional herbal isolate and 10 approved drugs) with the binding energy below –8.1 kcal/mol were selected as potential candidates to inhibit the SARS-CoV-2 S-protein, preventing the human cell infection and their replication. For instance, the ivermectin drug (present in our list of promise candidates) was recently used successful to control viral replication in vitro. MD simulations were performed for the three best ligands@S-protein complexes and the binding energies were calculated using the MM/PBSA approach. Overall, it is highlighted an important strategy, some key residues, and chemical groups which may be considered on clinical trials for COVID-19 outbreak.

description: We probe the dynamic evolution of a Stark wave packet in cesium using weak half-cycle pulses (HCP's). The state-selective field ionization(SSFI) spectra taken as a function of HCP delay reveal wave packet dynamics such as Kepler beats, Stark revivals and fractional revivals. A quantum-mechanical simulation explains the results as multi-mode interference induced by the HCP.

title: Insight into Bob Dylan’s chameleonic-like masculinity. Writings and songs, 1962 – 1970

Creators: name: Martinez, Sara
Publisher: name: Lancaster University

description: Bob Dylan has been mostly addressed from the perspective of his controversial relationship with politics, religion, and literature. Very few critics have focused on Bob Dylan’s masculinity and performativity, and so this thesis fills what is an evident gap in a seemingly crowded critical field. The thesis investigates the historical, social, and political factors that shaped the construction of Dylan’s masculinity and its importance in popular culture, drawing upon key critics and their corresponding works in order to analyze the way in which Dylan’s rebellion, fragmentation, and mystery were key features that destabilized the hegemonic models of performativity that prevailed during the Cold War. Between 1962 and 1970, Bob Dylan released ten studio albums that allowed him to display seven different sides of himself as an outsider and folk apprentice in Bob Dylan (1962), spokesman of his generation in The Freewheelin’ (1963), a prophet in The Times They Are A-Changin’ (1964), experimental artist in Bringing It All Back Home (1965), a man of action in Highway 61’ Revisited (1965), and as a rebellious, individualist performer in Blonde on Blonde (1966). Through Dylan’s shifting away from previous ‘spokesman of a generation’ through rebellious performer to a mature, bucolic ‘persona seems a drift towards conservatism and withdrawal from political engagement, what I call his ‘state of becoming’ allowed him to regenerate at personal and professional levels throughout the decade, even after his 1966 motorcycle crash. Dylan’s refusal to be the ‘voice of his generation’ is taken as evidence of his self-determination and ongoing refusal, but also of a dynamic relationship between audience and performer/ performance that changes over time. In analyzing Dylan’s albums, song lyrics, filmed performances and acting roles, and his experiments with art and literature, the thesis offers a different perspective on Dylan’s relationship to post-war masculinities.

description: Nutrient emissions from agricultural land are now widely recognized as one of the key contributors to poor water quality in local lakes, rivers and streams. Nutrient trading has been suggested as a regulatory tool to improve and protect water quality. However, farmers’ attitudes suggest that they are resistant to making the changes required under such a scheme. This paper develops a model of farmers’ resistance to change and their adoption of new management practices under nutrient trading regulation. We specify resistance as a bound on the adoption of new practices and allow this bound to relax as farmers’ resistance to change weakens. This paper reflects current work in progress as part of the author’s Master’s Thesis. Future work will extend and build upon the material presented here. We request that readers refer to this paper only in the absence of a more recent version. This paper has been prepared for the purposes of the New Zealand Agricultural and Resource Economics Society conference August 2012.

description: We canonically quantize the dynamics of the brane universe embedded into the five-dimensional Schwarzschild-anti-deSitter bulk space-time. We show that in the brane-world settings the formulation of the quantum cosmology, including the problem of initial conditions, is conceptually more simple than in the 3+1-dimensional case. The Wheeler-deWitt equation is a finite-difference equation. It is exactly solvable in the case of a flat universe and we find the ground state of the system. The closed brane universe can be created as a result of decay of the bulk black hole.

description: The adsorption behavior of Anastrozole (ANA) and Melphalan (MEL) anticancer drugs on the surface of silicene nanosheet (SNS) and functionalized SNS with folic acid (FA-SNS) is investigated and compared using the density functional theory (DFT) and molecular dynamics (MD) simulation. The DFT calculation is performed at the M06-2X/6–31G** level to characterize the optimized geometry properties of the designed complexes. The calculated adsorption energies are in the range from −65.59 to −144.23 kJ/mol, indicating the drug absorption on the surface of SNS and FA-SNS is exergonic. The π-π interaction between the drugs and SNS surface is the main driving force in the formation of drug-carriers complexes. The quantum theory of atoms in molecule (QTAIM) results reveal that the interaction of SNS and FA-SNS with both drugs has a non-covalent nature. The natural bond orbital (NBO) analysis shows that the charge is transferred from the drug molecules to carrier in all of the investigated complexes. Furthermore, MD simulations reveal that the contribution of van der Waals energy in drug-carrier interactions is more than electrostatic energy. Also, the obtained results demonstrate that the movement of drug molecules toward the carriers is spontaneous. Our study provides insights into the drug delivery capability of SNS and FA-SNS for the delivery of two drugs (ANA and MEL). Communicated by Ramaswamy H. Sarma

description: We collected over 6000 high-resolution spectra of four dozen field RR Lyrae (RRL) variables pulsating either in the fundamental (39 RRab) or in the first overtone (9 RRc) mode. We measured radial velocities (RVs) of four strong metallic and four Balmer lines along the entire pulsational cycle and derived RV amplitudes with accuracies better than 1$-$2~\kmsec. The new amplitudes were combined with literature data for 23~RRab and 3~RRc stars (total sample 74 RRLs) which allowed us to investigate the variation of the Bailey diagram (photometric amplitude versus period) when moving from optical to mid-infrared bands and to re-cast the Bailey diagram in terms of RV amplitudes. We found that RV amplitudes for RRab are minimally affected by nonlinear phenomena (shocks) and multi-periodicity (Blazhko effect). The RV slope ($\log P$--A(V$_r$)) when compared with the visual slope ($\log P$--A($V$)) is shallower and the dispersion, at fixed period, decreases by a factor of two. We constructed homogeneous sets of Horizontal Branch evolutionary models and nonlinear, convective pulsation models of RRLs to constrain the impact of evolutionary effects on their pulsation properties. Evolution causes, on the Bailey diagram based on RV amplitudes, a modest variation in pulsation period and a large dispersion in amplitude. The broad dispersion in period of the Bailey diagram is mainly caused by variation in RRL intrinsic parameters (stellar mass, chemical composition). Empirical evidence indicates that RV amplitudes are an optimal diagnostic for tracing the mean effective temperature across the RRab instability strip.
