description: A colouring of a graph $G=(V,E)$ is a mapping $c\colon V\to \{1,2,\ldots\}$ such that $c(u)\neq c(v)$ for every two adjacent vertices $u$ and $v$ of $G$. The {\sc List $k$-Colouring} problem is to decide whether a graph $G=(V,E)$ with a list $L(u)\subseteq \{1,\ldots,k\}$ for each $u\in V$ has a colouring $c$ such that $c(u)\in L(u)$ for every $u\in V$. Let $P_t$ be the path on $t$ vertices and let $K_{1,s}^1$ be the graph obtained from the $(s+1)$-vertex star $K_{1,s}$ by subdividing each of its edges exactly once.Recently, Chudnovsky, Spirkl and Zhong (DM 2020) proved that List $3$-Colouring is polynomial-time solvable for $(K_{1,s}^1,P_t)$-free graphs for every $t\geq 1$ and $s\geq 1$. We generalize their result to List $k$-Colouring for every $k\geq 1$. Our result also generalizes the known result that for every $k\geq 1$ and $s\geq 0$, List $k$-Colouring is polynomial-time solvable for $(sP_1+P_5)$-free graphs, which was proven for $s=0$ by Hoàng, Kamiński, Lozin, Sawada, and Shu (Algorithmica 2010) and for every $s\geq 1$ by Couturier, Golovach, Kratsch and Paulusma (Algorithmica 2015). We show our result by proving boundedness of an underlying width parameter. Namely, we show that for every $k\geq 1$, $s\geq 1$, $t\geq 1$, the class of $(K_k,K_{1,s}^1,P_t)$-free graphs has bounded mim-width and that a corresponding branch decomposition is "quickly computable" for these graphs.

description: Many real-world applications can be modelled as complex networks, and such networks include the Internet, epidemic disease networks, transport networks, power grids, protein-folding structures and others. Network integrity and robustness are important to ensure that crucial networks are protected and undesired harmful networks can be dismantled. Network structure and integrity can be controlled by a set of key nodes, and to find the optimal combination of nodes in a network to ensure network structure and integrity can be an NP-complete problem. Despite extensive studies, existing methods have many limitations and there are still many unresolved problems. This paper presents a probabilistic approach based on neighborhood information and node importance, namely, neighborhood information-based probabilistic algorithm (NIPA). We also define a new centrality-based importance measure (IM), which combines the contribution ratios of the neighbor nodes of each target node and two-hop node information. Our proposed NIPA has been tested for different network benchmarks and compared with three other methods: optimal attack strategy (OAS), high betweenness first (HBF) and high degree first (HDF). Experiments suggest that the proposed NIPA is most effective among all four methods. In general, NIPA can identify the most crucial node combination with higher effectiveness, and the set of optimal key nodes found by our proposed NIPA is much smaller than that by heuristic centrality prediction. In addition, many previously neglected weakly connected nodes are identified, which become a crucial part of the newly identified optimal nodes. Thus, revised strategies for protection are recommended to ensure the safeguard of network integrity. Further key issues and future research topics are also discussed.

description: We theoretically analyze the effect of the inversion symmetry breaking on the structure of the impurity molecular states in Weyl metals. We show that for the case of a highly noncentrosymmetric Weyl metallic host, the standard picture of the alternating bonding and antibonding orbitals breaks down, and a qualitatively different frustrated atomic state emerges. This is a consequence of the pseudogap closing and related delicate Fano interplay between intra- and inter-impurity scattering channels.

description: This research project was carried out so as to know the channels and margins of commercialization of the manzano chilli in the Estado de México. The research method consisted in identifying production regions and producers such as: Coatepex Harinas, Toluca, Villaguerrero, Zacango, Valle de Bravo Tenancingo, Calimaya and Texcatitlan. Direct observation and visits to producers and distributors were made, to request them to answer a market research in order to register the sale price in distribution centers or markets. The captured information was analyzed and allowed to identify that four agents that come into play in the commercialization process, such as: local wholesale suppliers, wholesale dealers, retailers and final consumers. Based on these findings, the margins were calculated by the proposed method by García, et. al.,1990, for the four routes found in the main market of Iztapalapa, in Mexico City, and the main markets of Ecatepec, Toluca and in the local market of Coatepec Harinas. The margins show that the more local vendors, wholesalers and intermediaries, the fewer profit margins for the producer are found as a result of the increment of the resale price.

title: Gain And Loss Of Progranulin Have Opposite Effects On Autophagy
Creators: name: Berlingieri, Stefania
Publisher: name: The Open University
Year: 2017

description: Progranulin (PGRN) is a widely expressed cysteine-rich, secreted glycoprotein with growth factor-like properties. PGRN is involved in both metabolism and neurodegeneration. It has recently emerged as an important regulatory adipokine of glucose metabolism and insulin sensitivity. Individuals with obesity and type 2 diabetes were shown to have increased serum PGRN levels. Heterozygous loss of function mutations in the gene encoding PGRN (GRN) have been described as the major cause of frontotemporal lobar degeneration (FTLD), the most common type of dementia after Alzheimer’s disease (AD), whereas homozygous mutations result in neuronal ceroid lipofuscinosis (NCL), an infantile onset disease. During my Ph.D thesis, I found that hepatic PGRN overexpression in mice results in autophagy impairment leading to metabolic syndrome whereas PGRN loss in mouse brains results in increased activation of autophagy through TNF receptor (TNFR) over-stimulation and C-Jun N-terminal kinase (JNK) activation. Excessive activation of brain autophagy is associated to neurodegeneration and either JNK or autophagy inhibition improve neuronal viability and dysfunction in PGRN deficient neurons and PGRN null C. elegans. Moreover, I found that gain and loss of PGRN have opposite effects on insulin-like growth factor 1 (IGF-1) level, implicated in both metabolism and neurodegenerative disorders. IGF-1 has been linked also to autophagy in several studies. Activation of IGF-1/insulin receptor substrate 2 (IRS-2) signaling, that has been previously demonstrated to activate autophagy, was found in PGRN deficient brain, thus suggesting a role for IGF-1 in the enhanced autophagy associated to neurodegeneration induced by PGRN loss. As stated above, FTLD is the most common form of early-onset dementia, after AD. However, how PGRN loss causes neurodegeneration is not fully understood. These results unravel novel mechanisms involved in neurodegeneration induced by PGRN loss and open new avenues for the investigation of new therapeutic studies in FTDL.

description: We present new observations of Lyman-$α$ (Ly$α$) Blob 1 (LAB1) in the SSA22 protocluster region ($z$ = 3.09) using the Keck Cosmic Web Imager (KCWI) and the Keck Multi-object Spectrometer for Infrared Exploration (MOSFIRE). By applying matched filtering to the KCWI datacube, we have created a narrow-band Ly$α$ image and identified several prominent features. By comparing the spatial distributions and intensities of Ly$α$ and H$β$, we find that recombination of photo-ionized HI gas followed by resonant scattering is sufficient to explain all the observed Ly$α$/H$β$ ratios. We further decode the spatially-resolved Ly$α$ profiles using both moment maps and Monte-Carlo radiative transfer (MCRT) modeling. By fitting a set of multiphase, 'clumpy' models to the observed Ly$α$ profiles, we are able to reasonably constrain many parameters, namely the HI number density in the inter-clump medium (ICM), the cloud volume filling factor, the random velocity and outflow velocity of the clumps, the HI outflow velocity of the ICM and the local systemic redshift. Our model has successfully reproduced the diverse Ly$α$ morphologies at different locations, and the main results are: (1) The observed Ly$α$ spectra require relatively few clumps per line-of-sight as they have significant fluxes at the line center; (2) The velocity dispersion of the clumps yields a significant broadening of the spectra as observed; (3) The clump bulk outflow can also cause additional broadening if the HI in the ICM is optically thick; (4) The HI in the ICM is responsible for the absorption feature close to the Ly$α$ line center.

description: Throughout the sixteenth century, the Ottoman Empire presented the most formidable challenge to the House of Habsburg’s predominance in Europe. This imperial rivalry and the military conflict which it generated made it vital that the Holy Roman Emperor and his advisors were kept informed about their powerful adversary to receive advance warning of impending attacks. For this reason, intelligence formed an important aspect of the day-to-day activities of the Aulic War Council, created in 1556 to coordinate the military defence of the Habsburg–Ottoman border, as well as the Austrian-Habsburgs’ resident ambassadors in Istanbul. Sources surviving in the Viennese archives provide valuable insights into the collection and dissemination of relevant information, as well as the organisation built by the Habsburg diplomatic presence in the Ottoman capital. In particular, this article examines ambassadorial expenditure accounts which provide insights into the financial aspects of Austrian-Habsburg intelligence in the period 1580–1583 and demonstrates that the business of intelligence was pursued by the Habsburgs in a more professional and orderly manner than historians usually acknowledge. Indeed, it was woven into the very fabric of the Aulic War Council as well as the Austrian-Habsburg diplomatic presence in Istanbul.

description: The Cobb-Douglas production function is most frequently mentioned in texts of Economic Theory and cubic production function proposed here is more convenient to show evidence when applied to agricultural production where producers try to streamline their production process at low levels of input use. In general, if the producer of low investment capacity has only money to implement a number of the units required for maximum efficiency in the production of a hectare of land, quantity of variable input to apply is the amount of available factor applied the proportion of fixed factor and in no way to get out of this usage rate of input. This result is particularly important because without that producer a single penny increase in spending relative to available, you can generate a recommendation that leads to higher incomes with their resource. Increased amount of product to obtain without increasing investment is one of the few technical-economic recommendations that may be available to low-income producers and limited availability of investment capital.

description: Die seit 2007 anhaltende Wirtschaftskrise und die makroökonomischen Folgen haben die strukturelle Krise der Bauwirtschaft weiter verstärkt. In diesem Umfeld hat der besonders über den Preis geführte Wettbewerb viele Firmen an den Rand der Insolvenz gebracht. Dabei schaffen es aber gerade jene Unternehmen in dieser Krise zu bestehen, welche sich und Ihr Produkt als Dienstleistung am Kunden verstehen und innovative Vertriebsprozesse entwickeln konnten. Das Erfolgsmodell ist geprägt von der Entwicklung optimaler und individueller Kundenlösungen, welche die Kundenzufriedenheit und die Wertschöpfung erhöhen. Die vorliegende Arbeit verfolgt das Ziel die notwendige Veränderung des Kommunikationsverhaltens in diesem Wirtschaftszweig, welche eine große Herausforderung darstellt, aufzuzeigen und über einen Stakeholder Relationship Ansatz Lösungen auszuarbeiten, diese oder ähnliche Krisen, jetzt und in Zukunft, bewältigen zu können.
description: The persistent economic crisis since 2007 and the macroeconomic consequences further strengthened the present structural crisis of the construction industry. In that environment, the construction industry focused on price competition which led many companies to the brink of insolvency. But for those companies which understood themselves and their product as a service to their customers and developed innovative sales processes could pass this crisis effectually. The successful model is characterized by the development of optimal and customized solutions to increase customer satisfaction and create value. The present study aims to identify the necessary changes of the communication behavior in this sector, which is a major challenge, and to develop a Stakeholder Relationship approach to cope with these and similar crises now and in the future.

description: We discuss the advantages of using metric theories of gravity with curvature-matter couplings in order to construct a relativistic generalisation of the simplest version of Modified Newtonian Dynamics (MOND), where Tully-Fisher scalings are valid for a wide variety of astrophysical objects. We show that these proposals are valid at the weakest perturbation order for trajectories of massive and massless particles (photons). These constructions can be divided into local and non-local metric theories of gravity with curvature-matter couplings. Using the simplest two local constructions in a FLRW universe for dust, we show that there is no need for the introduction of dark matter and dark energy components into the Friedmann equation in order to account for type Ia supernovae observations of an accelerated universe at the present epoch.

description: The Galactic positrons, as observed by their annihilation gamma-ray line at 0.511 MeV, are difficult to account for with astrophysical sources. It has been proposed that they are produced instead by dark matter annihilation or decay in the inner Galactic halo. To avoid other constraints, these processes are required to occur "invisibly," such that the eventual positron annihilation is the only detectable signal. However, electromagnetic radiative corrections to these processes inevitably produce real gamma rays (``internal bremsstrahlung"); this emission violates COMPTEL and EGRET constraints unless the dark matter mass is less than about 20 MeV.

description: The LIGO and Virgo Interferometers have so far provided 11 gravitational-wave (GW) observations of black-hole binaries. Similar detections are bound to become very frequent in the near future. With the current and upcoming wealth of data, it is possible to confront specific formation models with observations. We investigate here whether current data are compatible with the hypothesis that LIGO/Virgo black holes are of primordial origin. We compute in detail the mass and spin distributions of primordial black holes (PBHs), their merger rates, the stochastic background of unresolved coalescences, and confront them with current data from the first two observational runs, also including the recently discovered GW190412. We compute the best-fit values for the parameters of the PBH mass distribution at formation that are compatible with current GW data. In all cases, the maximum fraction of PBHs in dark matter is constrained by these observations to be $f_{\text{PBH}}\approx {\rm few}\times 10^{-3}$. We discuss the predictions of the PBH scenario that can be directly tested as new data become available. In the most likely formation scenarios where PBHs are born with negligible spin, the fact that at least one of the components of GW190412 is moderately spinning is incompatible with a primordial origin for this event, unless accretion or hierarchical mergers are significant. In the absence of accretion, current non-GW constraints already exclude that LIGO/Virgo events are all of primordial origin, whereas in the presence of accretion the GW bounds on the PBH abundance are the most stringent ones in the relevant mass range. A strong phase of accretion during the cosmic history would favour mass ratios close to unity, and a redshift-dependent correlation between high masses, high spins and nearly-equal mass binaries, with the secondary component spinning faster than the primary.

description: The discrete truncated Wigner approximation (DTWA) is a powerful tool for analyzing dynamics of quantum spin systems. Since the DTWA includes the leading-order quantum corrections to a mean-field approximation, it is naturally expected that the DTWA becomes more accurate when the range of interactions of the system increases. However, quantitative corroboration of this expectation is still lacking mainly because it is generally difficult in a large system to evaluate a timescale on which the DTWA is quantitatively valid. In order to investigate how the validity timescale depends on the interaction range, we analyze dynamics of quantum spin models with a step function type interaction subjected to a sudden quench of a magnetic field by means of both DTWA and its extension including the second-order correction, which is derived from the Bogoliubov-Born-Green-Kirkwood-Yvon equation. We also develop a formulation for calculating the second-order Rényi entropy within the framework of the DTWA. By comparing the time evolution of the Rényi entropy computed by the DTWA with that by the extension including the correction, we find that both in the one- and two-dimensional systems the validity timescale increases algebraically with the range of the step function type interaction.

The wake, analogous to a shock (hydraulic jump) in shallow water, appears for rod velocities v_R greater than a critical velocity c. We measure the half-angle, theta, of the wake as a function of v_R and layer depth, h. The angle satisfies the Mach relation, sin(theta)=c/v_R, where c=sqrt(gh), even for h as small as one particle diameter.

description: We present 3D magnetohydrodynamic (MHD) numerical simulations of the evolution of self--gravitating and weakly magnetized disks with an adiabatic equation of state. Such disks are subject to the development of both the magnetorotational and gravitational instabilities, which transport angular momentum outward. As in previous studies, our hydrodynamical simulations show the growth of strong m=2 spiral structure. This spiral disturbance drives matter toward the central object and disappears when the Toomre parameter Q has increased well above unity. When a weak magnetic field is present as well, the magnetorotational instability grows and leads to turbulence. In that case, the strength of the gravitational stress tensor is lowered by a factor of about~2 compared to the hydrodynamical run and oscillates periodically, reaching very small values at its minimum. We attribute this behavior to the presence of a second spiral mode with higher pattern speed than the one which dominates in the hydrodynamical simulations. It is apparently excited by the high frequency motions associated with MHD turbulence. The nonlinear coupling between these two spiral modes gives rise to a stress tensor that oscillates with a frequency which is a combination of the frequencies of each of the modes. This interaction between MHD turbulence and gravitational instabilities therefore results in a smaller mass accretion rate onto the central object.

Here, we further examine this interplay and its manifestation in incoherent scattering functions. In particular, we establish a dynamic length scale below which Fickian diffusion breaks down, as is observed in experiments and simulations. We describe the temperature dependence of this length scale in liquids of various fragilities, and provide analytical estimates for the van Hove and self-intermediate scattering functions.

description: A connection between relativistic quantum mechanics in the Foldy-Wouthuysen representation and the paraxial equations is established for a Dirac particle in external fields. The paraxial form of the Landau eigenfunction for a relativistic electron in a uniform magnetic field is determined. The obtained wave function contains the Gouy phase and significantly approaches to the paraxial wave function for a free electron.

description: This research was conducted in 2012 and point out the analysis of the technical and administrative practices used by milk farmers located in the so-called milk lace of the Province of Tundama in Boyacá, which is composed of the municipalities of Paipa , Tunja, Santa Rosa de Viterbo, Cerinza, Belen and Floresta. The purpose of this research was to identify the tools that entrepreneurs are using to manage the different activities in the process of producing this type of product. According to the above, the overall objective sought to identify the technical and administrative practices that these producers use as process -management in the production of fresh milk. It is important to highlight that these purposes are achieved from the formulation of specific objectives which can identify aspects such as: land tenure, company size, type of cattle, feeding, record types and technology among others. Always bearing in mind the knowledge the producer has regarding each one of the technical and administrative practices concerning the procurement and product handling. For the development of this work a descriptive research was used since the main concern was to describe key features of homogeneous sets, and thus to show the grounded study. The research method employed was deductive: where pre- established truths are taken as a general principle and subsequently be applied to particular cases and therefore confirm its validity. The data used in the determination of sample for the application of the surveys, was taken from a census of the size of farms according to the number of cattle, developed by ASOPADU (Agricultural Association of Sotaquira, Paipa and Tunja). This study highlights the economic and social importance that occurs in the process of production of fresh milk, since each one of the planned and properly supported activities (in terms of the improved cattle, meadows, use of appropriate technology, infrastructure and programming records) allow the entire process to ensure the product quality, and hence, when selling milk to find a better price on the market, facilitating the continuous improvement of the quality of life of the people involved in the first link of the chain.

description: The three-body photodisintegration of 3He has been measured with the CLAS detector at Jefferson Lab, using tagged photons of energies between 0.35 GeV and 1.55 GeV. The large acceptance of the spectrometer allowed us for the first time to cover a wide momentum and angular range for the two outgoing protons. Three kinematic regions dominated by either two- or three-body contributions have been distinguished and analyzed. The measured cross sections have been compared with results of a theoretical model, which, in certain kinematic ranges, have been found to be in reasonable agreement with the data.

description: Production rentability was evaluated under greenhouse conditions in the “Agronegocio SPR de RL, El Sureño Invernaderos” located in the community of “El Carpintero” municipality of Villa de Arista, San Luis Potosí, México. It counts with 170 hectares, but only 60 hectares are cultivated under the protected agriculture technology. For such effect, 10 years projections were used to calculate the indicators of the economic evaluation, i.e. present net value (PNV), relation cost-benefit (C/B), net benefit-investment relation (K/N) and the internal return rate (IRT). PNV = $ 95, 694, 461.00; C/B = 1.24; K/N = 5.43 and IRT = 51.02%. Results indicate that “Agronegocio el Sureño Invernaderos “ is profitable from the economic point of view. This indicates that due to the production under the protected agriculture technology, the company has a great opportunity of business, for having its market insured, with an 80% for exportation, and 20% of the remaining production are sold in the national market through agreements with the distributors and owned warehouses in the market on Mexico City
Scanning strategy for mapping the Cosmic Microwave Background anisotropies with Planck

description: We present simulations of different scanning strategies for the Planck satellite. We review the properties of slow- and fast-precession strategies in terms of uniformity of the integration time on the sky, the presence of low-redundancy areas, the presence of deep fields, the presence of sharp gradients in the integration time, and the redundancy of the scanning directions. We also compare the results obtained when co-adding all detectors of a given frequency channel. The slow-precession strategies allow a good uniformity of the coverage, while providing two deep fields. On the other hand, they do not allow a wide spread of the scan-crossing directions, which is a feature of the fast-precession strategies. However, the latter suffer from many sharp gradients and low-coverage areas on the sky. On the basis of these results, the strategy for Planck can be selected to be a slow (e.g. 4 month-period) sinusoidal or cycloidal scanning.

Improvements to the macroscopic-microscopic approach of nuclear fission

description: The well established macroscopic-microscopic (mac-mic) description of nuclear fission enables the prediction of fission fragment yields for a broad range of fissioning systems. In this work, we present several key enhancements to this approach. We improve upon the microscopic sector of nuclear potential energy surfaces by magnifying the resolution of the Lipkin-Nogami equations and strengthening the Strutinsky procedure, thus reducing spurious effects from the continuum. We further present a novel deterministic method for calculating fission dynamics under the assumption of strongly damped nucleonic motion. Our technique directly determines the evolution of the scissioned shape distribution according to the number of random walk steps rather than the statistical accumulation of fission events. We show that our new technique is equivalent to the Metropolis random walk pioneered over the past decade by Randrup and colleagues. It further improves upon it, as we remove the need for altering the nuclear landscape via a biased potential. With our final improvement, we calculate fission fragments mass and charge distributions using particle number projection, which affords the simultaneous calculation of both mass and charge yield distributions. Fission fragments are thus calculated from the quantum mechanical $A$-body states of the potential energy surface rather than the collective mass asymmetry variable ($α_{\rm g}$) of the Finite-Range Liquid-Drop Model (FRLDM) used in past work. We highlight the success of our enhancements by predicting the odd-even staggering and the charge polarization for the neutron-induced fission of ${}^{233}$U and ${}^{235}$U.

description: One monolayer of C60 on one monolayer of hexagonal boron nitride on nickel is investigated by photoemission. Between 150 and 250 K the work function decreases and the binding energy of the highest occupied molecular orbital (HOMO) increases by approx. 100 meV. In parallel, the occupancy of the, in the cold state almost empty, lowest unoccupied molecular orbital (LUMO) changes by 0.4 electrons. This charge redistribution is triggered by onset of molecular rocking motion, i.e. by orientation dependent tunneling between the LUMO of C60 and the substrate. The magnitude of the charge transfer is large and cannot be explained within a single particle picture. It is proposed to involve electron-phonon coupling where C60- polaron formation leads to electron self-trapping.

description: Additional file 14 : Figure S9. Effect of sgRNA targeting IL1RN and SLC4A1 promoters in HaCaT dCas9 P300 cells. HaCaT cells expressing dCas9 P300 were transduced with sgRNA plasmids containing previously-published sgRNA for the IL1RN promoter or the SLC4A1 promoter, in biological triplicate. Control cell lines were generated by transducing HaCaT dCas9 P300 cells with a sgRNA plasmid containing a scrambled guide (Scr) or no guide insert (Plasmid only; PO). qPCR was carried out using TaqMan assays for IL1RN or SLC4A1. Housekeeping genes used were TBP and YWHAZ. Graphs show fold change of gene expression relative to the cells containing the scrambled sgRNA. One-way ANOVA was carried out in GraphPad Prism: in both cases, the cells containing the targeting sgRNA had significantly higher gene expression than the scrambled control (P=0.002 for IL1RN; P=0.0001 for SLC4A1). Asterisks denote P < 0.05. Graphs show the mean fold-change in comparison with scrambled guide, +- SEM of triplicate cell lines.
