description: We consider the entanglement between two one-dimensional quantum wires (Luttinger Liquids) coupled by tunneling through a quantum impurity. The physics of the system involves a crossover between weak and strong coupling regimes characterized by an energy scale $T_B$, and methods of conformal field theory therefore cannot be applied. The evolution of the entanglement in this crossover has led to many numerical studies, but has remained little understood, analytically or even qualitatively. We argue in this Letter that the correct universal scaling form of the entanglement entropy $S$ (for an arbitrary interval of length $L$ containing the impurity) is $\partial S/\partial \ln L = f(L T_B)$. In the special case where the coupling to the impurity can be refermionized, we show how the universal function $f(L T_B)$ can be obtained analytically using recent results on form factors of twist fields and a defect massless-scattering formalism. Our results are carefully checked against numerical simulations.

description: Galactic superwinds may be driven by very hot outflows generated by overlapping supernovae within the host galaxy. We use the Chevalier & Clegg (CC85) wind model and the observed correlation between X-ray luminosities of galaxies and their SFRs to constrain the mass loss rates (\dot{M}_hot) across a wide range of star formation rates (SFRs), from dwarf starbursts to ultra-luminous infrared galaxies. We show that for fixed thermalization efficiency and mass loading rate, the X-ray luminosity of the hot wind scales as L_X ~ SFR^2, significantly steeper than is observed for star-forming galaxies: L_X ~ SFR. Using this difference we constrain the mass-loading and thermalization efficiency of hot galactic winds. For reasonable values of the thermalization efficiency (~ 10 M_sun/yr we find that \dot{M}_hot/SFR

Effect of disorder on the resistivity anisotropy near the electronic nematic phase transition in pure and electron-doped BaFe$_2$As$_2$

description: We show that the strain-induced resistivity anisotropy in the tetragonal state of the representative underdoped Fe-arsenides BaFe$_2$As$_2$, Ba(Fe$_{1-x}$Co$_x$)$_2$As$_2$ and Ba(Fe$_{1-x}$Ni$_x$)$_2$As$_2$ is independent of disorder over a wide range of defect and impurity concentrations. This result demonstrates that the anisotropy in the in-plane resistivity in the paramagnetic orthorhombic state of this material is not due to elastic scattering from anisotropic defects, and is most easily understood in terms of an intrinsic anisotropy in the electronic structure.
Quantum quench in a p + i p superfluid: Winding numbers and topological states far from equilibrium

description: We study the non-adiabatic dynamics of a 2D p+ip superfluid following a quantum quench of the BCS coupling constant. The model describes a topological superconductor with a non-trivial BCS (trivial BEC) phase appearing at weak (strong) coupling strengths. We extract the exact long-time asymptotics of the order parameter Δ(t) by exploiting the integrability of the classical p-wave Hamiltonian, which we establish via a Lax construction. Three different types of behavior can occur depending upon the strength and direction of the quench. In phase I, the order parameter asymptotes to zero. In phase II, Δ(t) goes to a non-zero constant. Phase III is characterized by persistent oscillations of Δ(t). For quenches within I and II, we determine the topological character of the asymptotic states. We show that two different formulations of the bulk topological winding number, although equivalent in the ground state, must be regarded as independent out of equilibrium. The first number Q characterizes the Anderson pseudospin texture of the initial state; we show that it is conserved. For non-zero Q, this leads to the prediction of a "gapless topological" state when Δ(t) goes to zero. The presence or absence of Majorana edge modes in a sample with a boundary is encoded in the second winding number W, formulated in terms of the retarded Green's function. We show that W can change following a quench across the quantum critical point. We discuss the implications for the (dis)appearance of Majorana edge modes. Finally, we show that the parity of zeros in the bulk out-of-equilibrium Cooper pair distribution function constitutes a Z2-valued quantum number, which is non-zero whenever W differs from Q. The pair distribution can in principle be measured using RF spectroscopy in an ultracold atom realization, allowing direct experimental detection of the bulk Z2 number.

Analyticity in spaces of convergent power series and applications

description: We study the analytic structure of the space of germs of an analytic function at the origin of \ww C^{\times m} , namely the space \germ{\mathbf{z}} where \mathbf{z}=\left(z\_{1},\cdots,z\_{m}\right) , equipped with a convenient locally convex topology. We are particularly interested in studying the properties of analytic sets of \germ{\mathbf{z}} as defined by the vanishing locus of analytic maps. While we notice that \germ{\mathbf{z}} is not Baire we also prove it enjoys the analytic Baire property: the countable union of proper analytic sets of \germ{\mathbf{z}} has empty interior. This property underlies a quite natural notion of a generic property of \germ{\mathbf{z}} , for which we prove some dynamics-related theorems. We also initiate a program to tackle the task of characterizing glocal objects in some situations.
Deep Ultraviolet Plasmonics Using Momentum-Resolved Electron Energy Loss Spectroscopy
Creators: Poursoti, Zohreh
Publisher: name: University of Alberta Library
Year: 2023

Plasmonics deals with the collective excitations of light coupled with free electrons in matter. It has widespread use in the fields of biosensing and nanoscale waveguiding due to the enhancement of the electric fields. My thesis deals with an important frontier in the field of plasmonics by analyzing excitations in the deep ultra-violet (DUV) and extreme ultra-violet (EUV) spectral region.

Specifically, I have employed a unique experimental method to probe light-matter interaction in the DUV and EUV regimes beyond the spectral range of conventional probes such as ellipsometers.

One long-term outcome of my work is to propose new sources of light in this regime where we envision future  applications such as DUV and EUV lithography. For this purpose, I have employed a unique momentum-resolved electron energy loss spectroscopy (q-EELS) technique to probe photonic modes in thin films at DUV and EUV energy scales. This thesis presents the theory and experimental results related to q-EELS of semiconductor thin films. EELS deals with the measurement of energy loss of relativistic electrons in a transmission electron microscope (TEM). Our technique, q-EELS is an important advancement that measures not only the energy loss but also the momentum loss of electrons thus giving insight on phenomena such as Cherenkov radiation. For the first time, we show the existence of DUV plasmons in Germanium, opening the possibility of using semiconductor materials as new plasmonic light sources. In addition, we analyze excitations in the extreme-ultra-violet regime in silicon and the temperature dependent characteristics of these high energy plasmonic excitations.
Optimal driving protocols for nano-sized devices and their dependence on couplings to reservoirs

description: The development of efficient artificial nanodevices poses challenges which are of fundamental and technological nature. Recent progress has been made in the context of finite-time thermodynamics. A central question in finite-time thermodynamics is to identify the optimal procedure to extract the greatest amount of work from a system operating under well-defined constraints. For externally controlled small systems, the optimal driving protocol maximizes the mean work spend in a finite-time transition between two given system states. For simplicity we consider an externally controlled single level system, which is embedded in a thermal environment and coupled to a particle reservoir. The optimal protocols are calculated from a master equation approach for different system-reservoir couplings. For open systems, the system-reservoir couplings are shown to have a striking influence on the optimal driving setup. We point out that the optimal protocols have discontinuous jumps at the initial and final times. Finally, this work provides a first attempt to extend these calculations to larger system sizes.

Exploring the Associations between Child Temperament, Parenting Behaviours and Styles, and Early Childhood Social-Emotional and Behavioural Development
Creators: Walker, Meghan A
Publisher: name: University of Alberta Library
Year: 2023

This dissertation contains three studies that contribute to the existing research by exploring the associations between child temperament, parenting, and early childhood social-emotional and behavioural development. The first study explores associations between child temperament, mothers’ and fathers’ observed parenting behaviours, and child anxiety problems in early childhood. The second study examines children’s temperament and mothers’ and fathers’ parenting styles as predictors of early childhood anxiety problems. Lastly, the third study explores similarities and differences between parenting styles of Asian-Canadian and European-Canadian heritage parents, including the relationship between parenting styles and early childhood externalizing and internalizing problems. The results of these studies indicate that: 1) associations between observed parenting behaviours and children’s anxiety problems differ between mothers and fathers; 2) higher levels of a negative affectivity temperament significantly predicts child anxiety problems, and parenting style moderating effects differ between mothers and fathers; and 3) there are more similarities than differences between parenting styles reported by Asian-Canadian and European-Canadian heritage parents, and an authoritative parenting style predicts lower levels of both externalizing problems and internalizing problems for European-Canadian and Asian-Canadian heritage children. These results support examining temperament as a risk factor for the development of anxiety problems in early childhood, as well as the importance of including both mothers and fathers in research focused on early childhood social-emotional and behavioural problems in young children.

description: Accelerator mass spectrometry radiocarbon (AMS 14C) dates (n = 78) from human bone collagen were analyzed in the largest high-resolution chronology study to date at the ancient city of Teotihuacan in central Mexico (ca. AD 1–550). Samples originate from the residential neighborhood of La Ventilla, located in the heart of this major urban center. Here, a trapezoidal model using Bayesian statistics is built from 14C dates combined with data derived from the stylistic analysis of ceramics from burial contexts. Based on this model, we suggest possible refinements to Teotihuacan’s ceramic chronology, at least within the La Ventilla neighborhood. We also explore the abandonment and reoccupation of La Ventilla after the political collapse of Teotihuacan in the Metepec and Coyotlatelco phases. Findings suggest that these ceramic phases began earlier than is currently projected and that the well-documented abandonment period of La Ventilla may have occurred more abruptly than originally estimated.

description: Bipartite entanglement entropies, calculated from the reduced density matrix of a subsystem, provide a description of the resources available within a system for performing quantum information processing. However, these quantities are not uniquely defined on a system of non-Abelian anyons. This paper describes how reduced density matrices and bipartite entanglement entropies (such as the von Neumann and Renyi entropies) may be constructed for non-Abelian anyonic systems, in ways which reduce to the conventional definitions for systems with only local degrees of freedom.

Deep Learning in Autonomous UAV Pursuit

Publisher: name: University of Alberta Library
Year: 2023

Unmanned aerial vehicles or UAVs have largely become and continue to be an inseparable part of modern warfare, security and surveillance systems, first aid response, aerial cinematography and many other sectors. Therefore, achieving full autonomy for UAVs and drones would ensure mass mobilization and utilization of these devices in large scale applications with more efficiency and precision without the need for deploying extensive human resources. A key aspect of autonomous flights is the capability of performing autonomous pursuits of target UAVs for military and civil purposes. Conventional autonomous pursuit algorithms rely on utilizing \lidar, radar and ultrasonic sensors or a combination and fusion of these devices. Each of theses sensors come with their disadvantages and shortcoming including a limited range of sight, massive data processing, expense and vulnerability to environment conditions. Thus, this research proposes a new sensor-free and vision-based algorithm for accomplishing fully autonomous UAV pursuit. This algorithm consists of two major parts including control and pose estimation. The flight controllers incorporate a digital four-axis proportional integral derivative (PID) framework and the pose estimator utilizes region-based convolutional neural networks (RCNN) for estimating a 3D bounding box over the target. The 3D bounding box keypoints are then extracted and combined with perspective-n-point (PnP) algorithm for estimating the precise relative pose of the target and pursuing it accordingly.

description: O Brasil foi um dos maiores produtores de cacau do mundo, sustentado principalmente pela região Sul da Bahia. Após a década de 1980, a vassoura-de-bruxa destruiu as plantações e os agricultores foram à falência. A busca mundial pelo cacau gourmet reacendeu o interesse por essa produção, cujo processo de fermentação e secagem é uma etapa fundamental para a obtenção do cacau fino, pois nesta fase são desenvolvidas muitas propriedades de processamento e atributos sensoriais. Esta pesquisa apresenta um sistema baseado em Blockchain-IoT para o controle e monitoramento destes eventos, visando catalogar em Smart Contracts informações valiosas para aperfeiçoamento do processo de fermentação do cacau e futuras pesquisas. Os sensores de IoT coletam dados e interferem no processo de fermentação/secagem e a Blockchain é usada como um banco de dados distribuído que implementa uma camada de segurança no nível do aplicativo. Uma prova de conceito foi modelada e o desempenho do sistema emulado foi avaliado no simulador OMNet, onde foi aplicada uma técnica baseada no protocolo SNMP para reduzir a quantidade de dados trocados e recursos servidos/consumidos. Em seguida, foi desenvolvida uma plataforma física e realizados experimentos preliminares em uma fazenda real, como forma de verificar a melhoria do processo de fermentação do cacau ao utilizar uma abordagem tecnológica.

Subjects: subject: Chemical Physics (physics.chem-ph)
subject: FOS: Physical sciences

description: We propose an analytical method for solving the problem of barrierless reactions in solution, modeled by a particle undergoing diffusive motion under the influence of both reactant and product potentials. The coupling between these two potentials is taken to be a Dirac Delta function. The diffusive motion in this paper is described by the Smoluchowskii equation. Our solution requires only the knowledge of the Laplace transform of the Green's function for the motion in both the uncoupled potentials. Our model is more general than all the earlier models, because we are the first one to consider the potential energy surfaces of both the reactant and product explicitly.

description: Stochastic transport of a two-dimensional (2D) dusty plasma liquid with a perpendicular magnetic field is studied. Superdiffusion, which is a type of non-Fickian transport, is found to occur especially at higher magnetic fields with $β$ of order unity. Here, $β= ω_c / ω_{pd}$ is the ratio of the cyclotron and plasma frequencies for dust particles. The mean-square displacement ${\rm {MSD}} = 4 D_αt^α$ is found to have an exponent $α> 1$, indicating superdiffusion, with $α$ increasing monotonically to $1.1$ as $β$ increases to unity. The 2D Langevin molecular dynamics simulation used here also reveals that another indicator of random particle motion, the velocity autocorrelation function (VACF), has a dominant peak frequency $ω_{peak}$ that empirically obeys $ω_{peak}^2 = ω_c^2+ ω_{pd}^2/4$.

description: It is well-known that the orbital effect of the magnetic field suppresses superconducting $T_c$. We show that for a system, which is in the Larkin-Ovchinnikov-Fulde-Ferrell (FFLO) state at zero external magnetic field, the orbital effect of an applied magnetic field can lead to the enhancement of the critical temperature higher than $T_c$ at zero field. We concentrate on two systems, where the in-plane FFLO-state was predicted recently. These are equilibrium S/F bilayers and S/N bilayers under nonequilibrium quasiparticle distribution. However, it is suggested that such an effect can take place for any plane superconducting heterostructure, which is in the in-plane FFLO-state (or is close enough to it) at zero applied field.

description: This research aims at exploring the identity path of children of foreign parents who represent a ?bridge? generation between their culture of origin and the culture of the country of their birth. The study will focus in particular on the process of teenagers asserting their subjectivity through a continuous negotiation between their emotional reference models and different symbolic values. The assumption of this work is to show how the identity push, which results from the adolescence evolutionary push combined with the double cultural background, could increase the drive for social success. Teenagers of second generations, in other words, are looking for a double recognition: on the one hand they want to access the adult world on the other they want to be recognized as member of the society where they live. This double set of aims results in a stronger motivation for social success. Two different theoretical approaches, cultural psychology and psychoanalysis, will be combined for this purpose, more specifically the relation between the person and the culture will be analyzed looking at the intertwining of the personal and relational psychological dimensions. As for the practical cases, this research will focus on teenagers who are enrolled in schools, born in Italy or moved to Italy for family reunion, and who attained good results at school.

description: Background: Substance abuse has become an increasingly serious socio-medical issue in recent decades. Human health is affected by the socio-cultural environment, which has a direct impact on his psychophysical development and well-being. However, sociocultural factors such as bad habits influence lifestyle and behavior, leading to significant health and social problems for substance abusers. Objective: The present study is to evaluate the phenomenology and socio-demographic characteristics of abusers and compare some of the characteristics randomly. The main objectives of this study are a. To evaluate the socio-demographic profile. b. To find out the pattern of substance use. c. To evaluate the association of phenomenology. d. To find out about substance-related disorders among the substance abuse patients. Materials and methods: There was an observational study conducted in the drug de-addiction unit at Taif, Eradah, and Mental Health Hospital in Saudi Arabia. This study included all substance abusers admitted to the hospital who met the inclusion and exclusion criteria. The study included patients of both genders admitted to the drug de-addiction unit between April 2021 and October 2022. Based on a descriptive statistical analysis, categorical variables were presented as frequencies and percentages. Results: An observational study was conducted for nearly one and a half years. We interviewed 358 substance abuse patients following a systematic sampling procedure in a peaceful, non-threatening environment. Among the 358 substance users, 353 (98.60%) were male and 5 (1.39%) were female. According to the survey, 117 (32.68%) of the participants reported abusing substances during their 31–40 years of age, followed by 102 (28.49%) during their 25 – 30 years of age. The predominant level of substance abuse was among the unemployed 163 (45.53%), followed by students 105 (29.33%). It was found that 58.66% of all respondents had initiated abuse between the ages of 18–24 years of age. Conclusion: In our study, combined substances like amphetamine and cannabis abusers were most prevalent because these are the most popular illicit drugs which are easily available. Islamic culture prohibits alcohol consumption both religiously and legally, making alcohol abuse the least prevalent of all drug addictions.

description: Der vorliegende Beitrag setzt sich mit dem Wandel der Architekturen von Heiligtümern vor dem Hintergrund der Nutzung durch verschiedene Einzelpersonen zur Repräsentation auseinander. Wiederholt wurden dabei die räumiche Orgisaion und die Gestalt der Bauten verändert. Religion wird in diesem Zusammenhang als kulturelles System aufgefasst, Heiligtümer als Teil der materiellen Kultur. Dazu wird exemplarisch die sog. Area Sacra des Largo Argentina in Rom im Zeitraum der späten Republik und Kaiserzeit betrachtet.
description: The present contribution deals with the change of architectures of sanctuaries through individuals, who used them for representational purposes and thus altered both the spatial organization and looks of the buildings. Religion is here understood as a cultural system, sanctuaries as part of material culture. To highlight these issues the focus centers on one example: the so-called Area Sacra of the Largo Argentina in Rome during Late Republican and Roman Imperial times.

description: We assume cold dark matter to possess a small bulk-viscous pressure which typically attenuates the growth of inhomogeneities. Explicit calculations, based on Eckart's theory of dissipative processes, reveal that for viscous cold dark matter the usual Newtonian approximation for perturbation scales smaller than the Hubble scale is no longer valid. We advocate the use of a neo-Newtonian approach which consistently incorporates pressure effects into the fluid dynamics and correctly reproduces the general relativistic dynamics. This result is of interest for numerical simulations of nonlinear structure formation involving nonstandard dark-matter fluids. We obtain upper limits on the magnitude of the viscous pressure by requiring that relevant perturbation amplitudes should grow sufficiently to enter the nonlinear stage.

description: Handgefertigte Keramikgefäße aus Megalithgräbern sind sehr gut geeignet, um die Dynamik weiblicher Kommunikations- und Interaktionsräume zu untersuchen. Durch ethnographische Vergleiche kann gezeigt werden, dass Keramik in einfachen bäuerlichen Gesellschaften überwiegend von Frauen hergestellt wurde. In den drei Zeitabschnitten 3500-3300, 3300-3050 und 3050-2800 v. Chr. können dabei unterschiedliche Strukturen entdeckt werden. Die Wahl des Wohnortes dieser Töpferinnen wirkte sowohl traditionsbildend als auch durchmischend auf die mittelneolithischen Kommunikationsstrukturen, wie mit Hilfe räumlich-statistischer Verfahren auf der Grundlage von 74 sehr gut erhaltenen doppelkonischen Gefäßen gezeigt werden soll.
description: Handmade pottery from megalithic graves is perfectly appropriate to investigate female spaces of communication and interaction. Ethnographic parallels show, that it was mostly women who produced pottery in early farming societies. For three time slices (3500-3300, 3300-3050 and 3050-2800 BC), different dynamics can be discovered. During these three periods, communication structures are on the one hand remaining constantly, on the other hand changing.
The choice of residence of these pottery-makers caused traditions and changes in female communication structures, as it can be seen from a spatial-statistical analysis of 74 well-preserved biconical pots.
Artificial Piezoelectricity in Silicon Phononic Crystals
Creators: Chowdhury, Golam Kibria

Certain materials, like quartz, are electrically polarized when they are strained.  This is called the direct piezoelectric effect.  It manifests naturally by the appearance of bound electrical charges at the surfaces of strained medium.  This is always accompanied by the converse effect, whereby a solid becomes strained when placed in an electric field.  Piezoelectricity has important applications in acoustic transducers, acousto-optic and RF devices, precision positioning instrumentation, to name a few.  However, since piezoelectric behavior is expressed only in non-centro symmetric crystals, such as quartz and lithium niobate, they have limited utility for on-chip applications.  In addition, the piezoelectric constants of these materials are typically weak, which limits the electromechanical conversion efficiency that can be achieved, with typical values of ~ 5.5% for single-crystal lithium niobate (LiNbO3) and ~20.8% for lead zirconium titanate (PZT).

Here we propose to develop a new class of meta-materials based on heterogeneous metal-on-silicon phononic crystals to realize artificial piezoelectricity in silicon, which is a centro-symmetric material.  We have developed analytical models in one-dimensional meta-atom structures to mimic piezoelectric behaviors, derive constitutive relations for the direct and converse piezoelectric effects, and determine the effective electromechanical coupling coefficient.  We found that near unity electromechanical coupling coefficient can in principle be achieved by driving the system at resonance, with the added advantage of low voltage operation.  Moreover, our structure permits scalable frequency operation up to tens of GHz.  We have also designed and simulated realistic 2D metal-on-silicon phononic crystal structures, with the aim of fabricating these structures on the Silicon-on-Insulator platform and experimentally demonstrating artificial piezoelectricity.  By tailoring both the electromagnetic and phononic band structures of these periodic structures, efficient excitation of coherent phononic modes can be achieved, which can potentially have novel applications in acousto-optics, acousto-electromagnetics, transducers, and quantum phononics.

description: DNA methylation occurs predominantly on cytosine-phosphate-guanine (CpG) dinucleotides in the mammalian genome, and the methylation landscape is maintained over mitotic cell division. It has been posited that coupling of maintenance methylation activity among neighbouring CpGs is critical to stability over cellular generations; however, the mechanism is unclear. We used mathematical models and stochastic simulation to analyze data from experiments that probe genome-wide methylation of nascent DNA post-replication in cells. We find that DNA methylation maintenance rates on individual CpGs are locally correlated, and the degree of this correlation varies by genomic regional context. By using theory of protein diffusion along DNA, we show that exponential decay of methylation rate correlation with genomic distance is consistent with enzyme processivity. Our results provide quantitative evidence of genome-wide methyltransferase processivity in vivo. We further developed a method to disentangle different mechanistic sources of kinetic correlations. From the experimental data, we estimate that an individual methyltransferase methylates neighbour CpGs processively if they are 36 basepairs apart, on average. But other mechanisms of coupling dominate for longer inter-CpG distances. Our study demonstrates that quantitative insights into enzymatic mechanisms can be obtained from replication-associated, cell-based genome-wide measurements, by combining data-driven statistical analyses with hypothesis-driven mathematical modelling.
Rigid Supersymmetry on 5-dimensional Riemannian Manifolds and Contact Geometry

description: In this note we generalize the methods of [1][2][3] to 5-dimensional Riemannian manifolds M. We study the relations between the geometry of M and the number of solutions to a generalized Killing spinor equation obtained from a 5-dimensional supergravity. The existence of 1 pair of solutions is related to almost contact metric structures. We also discuss special cases related to $M = S1 \times M4$, which leads to M being foliated by submanifolds with special properties, such as Quaternion-Kahler. When there are 2 pairs of solutions, the closure of the isometry sub-algebra generated by the solutions requires M to be S3 or T3-fibration over a Riemann surface. 4 pairs of solutions pin down the geometry of M to very few possibilities. Finally, we propose a new supersymmetric theory for N = 1 vector multiplet on K-contact manifold admitting solutions to the Killing spinor equation.

Characterization of Dextransucrase and Branching Sucrase of Apilactobacillus kunkeei DSM 12361

Glycoside hydrolase family 70 (GH70) glucansucrases have various applications in both food and non-food industries. This study reports the characterization of two GH70 enzymes, dextransucrase and branching sucrase, of Apilactobacillus kunkeei DSM 12361 on a range of acceptor substrates. GtfZ of A. kunkeei DSM 12361 possesses two catalytic domains, CD1 and CD2, which are interconnected by a glucan binding domain (GBD). For this study, dextransucrase CD1-GBD is a combination of the first catalytic domain CD1 with GBD, while branching sucrase GBD-CD2 is composed of GBD combined with the second catalytic domain CD2. In addition to sucrose as the sole substrate, CD1-GBD was active when dextran was available as an acceptor substrate. It was also found that CD1-GBD was active on reuteran and modified potato amylose. GBD-CD2 was also active on various substrates such as dextran, reuteran, and modified amylose, which proves the ability of GBD-CD2 to introduce branches on polymer chains with different linkage types. The activity of CD1-GBD and GBD-CD2 showed a preference for α-(1→6) glycosidic linkage in the acceptor substrate. The ability of CD1-GBD and GBD-CD2 to act on starch-derived molecules, such as potato amylose, is crucial in synthesizing polymers at a low cost. The activity on a wide range of substrates increases the options for producing polymers with different properties.

description: We consider a generic basic semi-algebraic subset $\mathcal{S}$ of the space of generalized functions, that is a set given by (not necessarily countably many) polynomial constraints. We derive necessary and sufficient conditions for an infinite sequence of generalized functions to be realizable on $\mathcal{S}$, namely to be the moment sequence of a finite measure concentrated on $\mathcal{S}$. Our approach combines the classical results about the moment problem on nuclear spaces with the techniques recently developed to treat the moment problem on basic semi-algebraic sets of $\mathbb{R}^d$. In this way, we determine realizability conditions that can be more easily verified than the well-known Haviland type conditions. Our result completely characterizes the support of the realizing measure in terms of its moments. As concrete examples of semi-algebraic sets of generalized functions, we consider the set of all Radon measures and the set of all the measures having bounded Radon-Nikodym density w.r.t. the Lebesgue measure.

description: In 2013, inclusive J/psi measurements in p-Pb collisions were performed at the LHC at sqrt(sNN) = 5.02 TeV, in order to measure the effects related to the cold nuclear matter on the J/psi production. Their evaluation is important in order to be able to disentangle hot and cold nuclear matter effects in Pb-Pb collisions. In this contribution, results on the inclusive J/psi production in p-Pb collisions, in the dimuon decay channel at forward and backward rapidity, down to zero transverse momentum, are presented and compared to theoretical models.
