description: We study the higher-spin gauge theory in six-dimensional anti-de Sitter space $AdS_6$ that is based on the exceptional Lie superalgebra $F(4)$. The relevant higher-spin algebra was constructed in arXiv:1409.2185 [hep-th]. We determine the spectrum of the theory and show that it contains the physical fields of the Romans $F(4)$ gauged supergravity. The full spectrum consists of an infinite tower of unitary supermultiplets of $F(4)$ which extend the Romans multiplet to higher spins plus a single short supermultiplet. Motivated by applications to this novel supersymmetric higher-spin theory as well as to other theories, we extend the known one-loop tests of $AdS/CFT$ duality in various directions. The spectral zeta-function is derived for the most general case of fermionic and mixed-symmetry fields, which allows one to test the Type-A and B theories and supersymmetric extensions thereof in any dimension. We also study higher-spin doubletons and partially-massless fields. While most of the tests are successfully passed, the Type-B theory in all even dimensional anti-de Sitter spacetimes presents an interesting puzzle: the free energy as computed from the bulk is not equal to that of the free fermion on the CFT side, though there is some systematics to the discrepancy.

description: Scattering amplitudes in quantum field theories have intricate analytic properties as functions of the energies and momenta of the scattered particles. In perturbation theory, their singularities are governed by a set of nonlinear polynomial equations, known as Landau equations, for each individual Feynman diagram. The singularity locus of the associated Feynman integral is made precise with the notion of the Landau discriminant, which characterizes when the Landau equations admit a solution. In order to compute this discriminant, we present approaches from classical elimination theory, as well as a numerical algorithm based on homotopy continuation. These methods allow us to compute Landau discriminants of various Feynman diagrams up to 3 loops, which were previously out of reach. For instance, the Landau discriminant of the envelope diagram is a reducible surface of degree 45 in the three-dimensional space of kinematic invariants. We investigate geometric properties of the Landau discriminant, such as irreducibility, dimension and degree. In particular, we find simple examples in which the Landau discriminant has codimension greater than one. Furthermore, we describe a numerical procedure for determining which parts of the Landau discriminant lie in the physical regions. In order to study degenerate limits of Landau equations and bounds on the degree of the Landau discriminant, we introduce Landau polytopes and study their facet structure. Finally, we provide an efficient numerical algorithm for the computation of the number of master integrals based on the connection to algebraic statistics. The algorithms used in this work are implemented in the open-source Julia package Landau.jl available at https://mathrepo.mis.mpg.de/Landau/.

description: This systematic review examines the effects of the subset of restorative justice programs that has been tested most extensively: a face-to-face Restorative Justice Conference (RJC) “that brings together offenders, their victims, and their respective kin and communities, in order to decide what the offender should do to repair the harm that a crime has caused” (Sherman and Strang, 2012: 216). The Review investigates the effects of RJCs on offenders’ subsequent convictions (or in one case arrests) for crime, and on several measures of victim impact. The review considers only randomized controlled trials in which victim and offenders consented to meet prior to random assignment, the analysis of which was based on the results of an “intention-to-treat” analysis. A total of ten experiments with recidivism outcomes were found that met the eligibility criteria, all of which also had at least one victim impact measure. Our synthesis of these experiments shows that, on average, RJCs cause a modest but highly cost-effective reduction in repeat offending, with substantial benefits for victims. A cost-effectiveness estimate for the seven United Kingdom (UK) experiments found a ratio of 8 times more benefit in costs of crimes prevented than the cost of delivering RJCs.

description: This research was conducted to examine the factors influencing organizational commitment in the case of Commercial Bank of Ethiopia (CBE) using drivers of organizational commitment as an indicator. Data was gathered from 198 professional and managerial employees of CBE Addis Ababa. Descriptive and inferential statistics was used to analyze the data and also cluster sampling was used followed by stratified random sampling to select the samples. Primary data were collected using five Point Likert-Scale questionnaires and 185 responses were properly filled and returned. Statistical package for social science studies (SPSS) version 20 was used to analyze empirical data collected through the close ended questionnaire. The independent variables are compensation, job security, Training and development, working conditions, supervisor support culture, and organizational justice whereas the dependent variable is employees' organizational commitment. The mean and standard deviation of the dependent and independent variables were computed and interpreted. Pearson correlation Coefficient (r) was used to determine the relationship between each independent variable with the dependent variable. The descriptive statistics result indicated that the mean value for compensation, Supervisor Support Culture, training and development, and Organizational Commitment were below average which indicate that employees in general are not committed in CBE. Therefore, it is better that the Bank should revise its compensation scheme, give supervisors training to develop their skill, give employees different trainings and help them to tryout their training on the job etc.

description: El talento humano es el que hace que las organizaciones funcionen, son ellos los encargados de controlar la calidad, diseñar, producir, distribuir los productos y servicios, así como de establecer sus objetivos y estrategias. Sin gente eficiente es imposible que una organización logre sus objetivos. Las empresas están en disposición de conocer los niveles de felicidad de sus empleados y hacer los cambios necesarios para mejorar su rendimiento o, dicho de otro modo, para que sean más felices y su trabajo luzca más dentro de la organización. Las organizaciones que quieran tener éxito no van a tener más remedio que buscar ventajas competitivas en aspectos relacionados con la felicidad de sus empleados, lo que involucra temas como la diversidad de la mano de obra o la relación entre trabajo y vida. La importancia que tiene el empleado dentro de la empresa es enorme debido a que este es el generador de que esta sea realmente productiva, pero este tipo de producción no puede estar alejado de la parte humana, porque ahora el empleado ya no solo es un recurso sino una parte integral del proceso. Es de vital importancia que las empresas miren a su capital humano, quién debe estar satisfecho con sus condiciones laborales. Además se hace referencia a una parte muy importante, el que la satisfacción laboral no solo es medida en el aspecto salarial, sino que engloba, el que el empleado debe tener una ergonomía completa, para que su desempeño sea apto para el cumplimiento de los objetivos institucionales. De lo anterior nace la oportunidad de aplicar en la medida un modelo que analice la gestión humana a una empresa real como Bancolombia, contribuyendo de manera efectiva en la visión gerencial integral tal como la que se evidencia en las grandes corporaciones exitosas contemporáneas. Esta empresa ha logrado consolidarse y posicionarse en el sector financiero, obteniendo un crecimiento operacional considerable, razón que permite a los autores de este proyecto la oportunidad de realizar un proyecto titulado “Análisis del modelo de gestión humana de la entidad financiera Bancolombia” como una prueba piloto para demostrar la idoneidad profesional.

description: Atmospheric chemical abundances of giant planets lead to important constraints on planetary formation and migration. Studies have shown that giant planets that migrate through the protoplanetary disk can accrete substantial amounts of oxygen-rich planetesimals, leading to super-solar metallicities in the envelope and solar or sub-solar C/O ratios. Pebble accretion has been demonstrated to play an important role in core accretion and to have growth rates that are consistent with planetary migration. The high pebble accretion rates allow planetary cores to start their growth beyond 10 AU and subsequently migrate to cold (>~ 1 AU), warm (~0.1 AU- 1AU) or hot (

Cannabinoids production in Cannabis sativa L.: An in vitro approach
Creators: name: Farag, Sayed
Publisher: name: Technische Universität Dortmund
Year: 2014
Subjects: subject: 660

description: Cannabis sativa L. (Cannabaceae) is the oldest known medicinal plant. For millennia, the plant has also been used for fibre and oil production.The most prominent feature of C. sativa is the psychoactive effect ascribed to its secondary metabolites, cannabinoids (mainly to tetrahydrocannabinol, THC). However, many other pharmacological properties of the aforementioned specialized compounds have been described. Currently, the demand for THC for various medical applications is substantial, while cultivation and breeding of Cannabis in most countries is strictly regulated and limited to serving research purposes and meeting therapeutic needs. Therefore, the hereby proposed and discussed production of THC using in vitro cultures could be a viable alternative. In the work presented here, in vitro organogenesis from callus cultures (undifferentiated plant cell masses grown on solid media) was successfully established, ultimately resulting in regeneration of the complete C. sativa plant. Further, production of THC as well as other important cannabinoids was achieved in cell suspension, hairy root and trichome cultures of Cannabis. The optimal combination of phytohormones, as applied to the B5 growth medium, fostering the development of meristemoids from callus cultures was: 1-naphthaleneacetic acid (NAA), 6-benzylaminopurine (BA) and adenine hemisulfate salt (AS) in respective concentrations of 0.5, 5 and 40 mg/l. Concurrently, the most favourable augmentation protocols of the B5 medium for the induction and differentiation of shootlets (small plants with leaves but without roots) were: 0.5 mg/l of gibberelic acid (GA3) or 0.25 mg/l of thidiazouron (TDZ) and 3 mg/l of GA3 (8.5 ± 1.73 and 7.25 ±1.03 shootlets/callus, respectively). The subsequent root formation of shootlets was most prominent after supplementation with 1.5 mg/l of indole-3-acetic acid (IAA). In vitro acclimatized plants growing in Erlenmeyer flasks formed tetrahydrocannabinolic acid (THCA), cannabigerolic acid (CBGA) and cannabidiolic acid (CBDA), retrieved at respective concentrations of about 0.33, 0.45 and 157.1 mg/g fresh weight. In contrast, ex vitro acclimatized plants (grown hydroponically for 8 weeks) synthesized THCA, THC, CBGA, cannabigerol (CBG) and CBDA at corresponding concentrations of 1.54, 28.30, 6.0, 0.125 and 1121.4 mg/g fresh weight. The obtained results confirmed the generation of pharmacologically important cannabinoids; however, the biosynthetic abilities of the investigated cell and hairy root cultures did not provide sufficient levels of the valuable metabolites to warrant scaling-up of the proposed in vitro production platform.
Absence of evidence of superconductivity in sulfur hydride in optical reflectance experiments

description: Capitani and coworkers [1] reported that infrared optical reflectance measurements provided evidence for a superconducting transition in sulfur hydride [2] under 150 GPa pressure, and that the transition is driven by the electron-phonon interaction. Here we argue that the measured data did not provide evidence that the system undergoes a transition to a superconducting state, nor do the data support any role of phonons in driving a transition. Rather, the data are consistent with the system remaining in the normal state down to temperature 50K, the lowest temperature measured in the experiment. This calls into further question [3,4] the generally accepted view [5] that sulfur hydride under pressure is a high temperature superconductor.

description: In this paper we investigate the sensitivity of the LWR model on network to its parameters and to the network itself. The quantification of sensitivity is obtained by measuring the Wasserstein distance between two LWR solutions corresponding to different inputs. To this end, we propose a numerical method to approximate the Wasserstein distance between two density distributions defined on a network. We found a large sensitivity to the traffic distribution at junctions, the network size, and the network topology.

Mitochondria contain their own genome which must be maintained for proper cellular function; this includes its replication and repair. This thesis explores mitochondrial DNA (mtDNA) helicases in Dictyostelium discoideum, an amoeba and model for mitochondrial genetics. Firstly Twm1, a replicative mtDNA helicase and Dictyostelium homologue of mammalian Twinkle, was identified and characterised, demonstrating that Twm1 unwinds DNA for replication and, unlike human Twinkle, possesses primase functionality. Twm1 was also found to recognise a sequence containing a likely origin of mtDNA replication, suggesting its involvement in initiating replication. It is important that mtDNA is properly maintained should it become damaged, processes in which Pif1 helicases are believed to play important roles. In this thesis, members of the Pif1 family in amoebae have been identified. While most organisms possess one or two Pif1 homologues, this study demonstrated that amoebae typically possess between two and nine; the D. discoideum genome encodes three. This work also identified the first collection of Pif1 helicases that contain additional domains, which might provide novel functionality for amoebal Pif1 proteins. Phylogenetic analysis suggested these domains were acquired through various genetic events, including horizontal gene transfer from bacteria and fungi. Finally, a candidate Pif1 homologue from D. discoideum (DdPif1) was experimentally characterised to understand its role in mtDNA maintenance. The results suggest that DdPif1 is involved in mtDNA recovery from both oxidative damage and fragmentation. Furthermore, DdPif1 was shown to be an active helicase important for resolving G-quadruplex DNA structures, which are predicted to form throughout the mitochondrial genome. Conversely, Twm1 was shown to be incapable of unwinding G-quadruplex containing DNA. This work has highlighted the significance of using Dictyostelium as a model for mitochondrial genetics, and has contributed to the understanding of mtDNA maintenance outside mammalian systems, mtDNA helicase functionality and their roles in maintaining the mitochondrial genome.

description: We use the long-wavelength formalism to investigate the level of bispectral non-Gaussianity produced in two-field inflation models with standard kinetic terms. Even though the Planck satellite has so far not detected any primordial non-Gaussianity, it has tightened the constraints significantly, and it is important to better understand what regions of inflation model space have been ruled out, as well as prepare for the next generation of experiments that might reach the important milestone of Delta f_NL(local) = 1. We derive an alternative formulation of the previously derived integral expression for f_NL, which makes it easier to physically interpret the result and see which types of potentials can produce large non-Gaussianity. We apply this to the case of a sum potential and show that it is very difficult to satisfy simultaneously the conditions for a large f_NL and the observational constraints on the spectral index n_s. In the case of the sum of two monomial potentials and a constant we explicitly show in which small region of parameter space this is possible, and we show how to construct such a model. Finally, the new general expression for f_NL also allows us to prove that for the sum potential the explicit expressions derived within the slow-roll approximation remain valid even when the slow-roll approximation is broken during the turn of the field trajectory (as long as only the epsilon slow-roll parameter remains small).

description: The assessment of the thermal properties of walls is essential for accurate building energy simulations that are needed to make effective energy-saving policies. These properties are usually investigated through in-situ measurements of temperature and heat flux over extended time periods. The one-dimensional heat equation with unknown Dirichlet boundary conditions is used to model the heat transfer process through the wall. In [F. Ruggeri, Z. Sawlan, M. Scavino, R. Tempone, A hierarchical Bayesian setting for an inverse problem in linear parabolic PDEs with noisy boundary conditions, Bayesian Analysis 12 (2) (2017) 407--433], it was assessed the uncertainty about the thermal diffusivity parameter using different synthetic data sets. In this work, we adapt this methodology to an experimental study conducted in an environmental chamber, with measurements recorded every minute from temperature probes and heat flux sensors placed on both sides of a solid brick wall over a five-day period. The observed time series are locally averaged, according to a smoothing procedure determined by the solution of a criterion function optimization problem, to fit the required set of noise model assumptions. Therefore, after preprocessing, we can reasonably assume that the temperature and the heat flux measurements have stationary Gaussian noise and we can avoid working with full covariance matrices. The results show that our technique reduces the bias error of the estimated parameters when compared to other approaches. Finally, we compute the information gain under two experimental setups to recommend how the user can efficiently determine the duration of the measurement campaign and the range of the external temperature oscillation.

description: We address spin transport in the easy-axis Heisenberg spin chain subject to integrability-breaking perturbations. We find that spin transport is subdiffusive with dynamical exponent $z=4$ up to a timescale that is parametrically long in the anisotropy. In the limit of infinite anisotropy, transport is subdiffusive at all times; for large finite anisotropy, one eventually recovers diffusion at late times, but with a diffusion constant independent of the strength of the integrability breaking perturbation. We provide numerical evidence for these findings, and explain them by adapting the generalized hydrodynamics framework to nearly integrable dynamics. Our results show that the diffusion constant of near-integrable interacting spin chains is generically not perturbative in the integrability breaking strength.

description: We characterize surface-plasmon polaritons at lossy planar interfaces between one dispersive and one nondispersive linear isotropic homogeneous media, i.e., materials or metamaterials. Specifically we solve Maxwell's equations to obtain strict bounds for the permittivity and permeability of these media such that satisfying these bounds implies surface-plasmon polaritons successfully propagate at the interface, and violation of the bounds impedes propagation, i.e., the field delocalizes from the surface into the bulk. Our characterization of surface-plasmon polaritons is valuable for checking viability of a proposed application, and, as an example, we employ our method to falsify a previous prediction that surface-plasmon propagation through a surface of a double-negative refractive index medium occurs for any permittivity and permeability; instead we show that propagation can occur only for certain medium parameters.

description: The well-quasi-ordering (i.e., a well-founded quasi-ordering such that all antichains are finite) that defines well-structured transition systems (WSTS) is shown not to be the weakest hypothesis that implies decidability of the coverability problem. We show coverability decidable for monotone transition systems that only require the absence of infinite antichains and call well behaved transitions systems (WBTS) the new strict superclass of the class of WSTS that arises. By contrast, we confirm that boundedness and termination are undecidable for WBTS under the usual hypotheses, and show that stronger monotonicity conditions can enforce decidability. Proofs are similar or even identical to existing proofs but the surprising message is that a hypothesis implicitely assumed minimal for twenty years in the theory of WSTS can meaningfully be relaxed, allowing more orderings to be handled in an abstract way.

Anomalous Dimensions and the Renormalizability of the Four-Fermion Interaction

description: We show that when the dynamical dimension of the $\barψψ$ operator is reduced from three to two in a fermion electrodynamics with scaling, a $g(\barψψ)^2+g(\barψiγ^5ψ)^2$ four-fermion interaction which is dressed by this electrodynamics becomes renormalizable. In the fermion-antifermion scattering amplitude every term in an expansion to arbitrary order in $g$ is found to diverge as just a single ultraviolet logarithm (i.e. no log squared or higher), and is thus made finite by a single subtraction. While not necessary for renormalizability per se, the reduction in the dimension of $\barψψ$ to two leads to dynamical chiral symmetry breaking in the infrared, with the needed subtraction then automatically being provided by the theory itself through the symmetry breaking mechanism, with there then being no need to introduce the subtraction by hand. Since the vector and axial vector currents are conserved, they do not acquire any anomalous dimension, with the four-fermion $(\barψγ^μψ)^2$ and $(\barψγ^μγ^5ψ)^2$ interactions instead having to be controlled by the standard Higgs mechanism.

A branching random walk among disasters

description: We consider a branching random walk in a random space-time environment of disasters where each particle is killed when meeting a disaster. This extends the model of the "random walk in a disastrous random environment" introduced by [15]. We obtain a criterion for positive survival probability, see Theorem 1. The proofs for the subcritical and the supercritical cases follow standard arguments, which involve moment methods and a comparison with an embedded branching process with i.i.d. offspring distributions. The proof of almost sure extinction in the critical case is more difficult and uses the techniques from [8]. We also show that, in the case of survival, the number of particles grows exponentially fast.
Evolution of the immune pore-forming protein perforin

Subjects: Uncategorized

description: The granule-exocytosis pathway is used by cytotoxic lymphocytes to kill virally infected, malignant and foreign cells. The pore-forming protein perforin is central to this pathway and organisms deficient in perforin cannot control viral infection. Although this mechanism of killing is conserved in bony vertebrates, cytotoxic cells are present in other chordates and invertebrates, and their cytotoxic mechanism has not been elucidated. In order to understand the evolution of this pathway, here the origins and evolution of perforin has been investigated. Perforin genes are present in the genomes of all cartilaginous and bony vertebrates, but not in more primitive chordates. In placental mammals perforin is a single copy gene, but there are multiple perforin genes in all lineages predating marsupials, except birds. Comparisons of these paralogues show that they mainly arose from lineage-specific gene duplications in multiple taxa, suggesting acquisition of new roles or different modes of regulation. Perforin is a member of a superfamily of proteins that share the membrane attack complex/perforin (MACPF) domain. A model for the evolution of perforin via the duplication of another MACPF family member, the ancient MPEG1 gene, is presented. This model also includes a relationship to the functionally related complement proteins C6, C7, C8 and C9, and to the more distantly related neural MACPF proteins. Only partially covered (incomplete) perforin genes were found in bird genomes, so the full-length chicken perforin gene was cloned and characterised. This encodes a protein with an extended C-terminus that is 90 amino acids longer than any mammalian perforin. The pore-forming ability of perforins from flounder and chicken was compared to that of the well characterised mouse perforin. These proteins did not display any activity, suggesting a model in which most perforin proteins (other than mouse perforin) are synthesised as inactive precursors.

description: We analyse the kinematics of cosmological spacetimes with nonzero torsion, in the framework of the classical Einstein-Cartan gravity. After a brief introduction to the basic features of spaces with non-vanishing torsion, we consider a family of observers moving along timelike worldlines and focus on their kinematic behaviour. In so doing, we isolate the irreducible variables monitoring the observers' motion and derive their evolution formulae and associated constraint equations. Our aim is to identify the effects of spacetime torsion, and the changes they introduce into the kinematics of the standard, torsion-free, cosmological models. We employ a fully geometrical approach, imposing no restrictions on the material content, or any a priori couplings between torsion and spin. Also, we do not apply the familiar splitting of the equations, into a purely Riemannian component plus a torsion/spin part, at the start of our study, but only introduce it at the very end. With the general formulae at hand, we use the Einstein-Cartan field equations to incorporate explicitly the spin of the matter. The resulting formulae fully describe the kinematics of dynamical spacetimes within the framework of the Einstein-Cartan gravity, while in the special case of the so-called Weyssenhoff fluid, they recover results previously reported in the literature.
