Decoupling Gravity in F-Theory
Creators: name: Cordova, Clay

Year: 2009
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We study seven-brane SU(5) GUT models of string phenomenology which can be consistently analyzed in a purely local framework. The requirement that gravity can decouple constrains the form of four-dimensional physics as well as the geometry of spacetime. We rule out a large family of candidate UV completions of such models and derive a priori constraints on the local singularities of compact elliptic Calabi-Yau fourfolds. These constraints are strong enough to obstruct a wide class of brane constructions from UV completion in string theory. It is demonstrated that consistent local models always have exotic Yukawa coupling structures, and hidden sectors or interesting non-perturbative superpotentials which merit further investigation.

description: The valence and conduction band structures of In₂O₃ have been measured using a combination of valence band x-ray photoemission spectroscopy, O K-edge resonant x-ray emission spectroscopy, and O K-edge x-ray absorption spectroscopy. Excellent agreement is noted between the experimental spectra and O 2p partial density of states calculated within hybrid density functional theory. Our data are consistent with a direct band gap for In₂O₃.

Strichartz type estimates for fractional heat equations

Subjects: subject: Analysis of PDEs (math.AP)

description: We obtain Strichartz estimates for the fractional heat equations by using both the abstract Strichartz estimates of Keel-Tao and the Hardy-Littlewood-Sobolev inequality. We also prove an endpoint homogeneous Strichartz estimate via replacing $ L^{\infty}_{x}(\mathbb{R}^{n})$ by $BMO_{x}(\mathbb{R}^{n})$ and a parabolic homogeneous Strichartz estimate. Meanwhile, we generalize the Strichartz estimates by replacing the Lebesgue spaces with either Besov spaces or Sobolev spaces. Moreover, we establish the Strichartz estimates for the fractional heat equations with a time dependent potential of an appropriate integrability. As an application, we prove the global existence and uniqueness of regular solutions in spatial variables for the generalized Navier-Stokes system with $L^{r}(\mathbb{R}^{n})$ data.

Inferring a property of a large system from a small number of samples

description: Inferring the value of a property of a large stochastic system is a difficult task when the number of samples is insufficient to reliably estimate the probability distribution. The Bayesian estimator of the property of interest requires the knowledge of the prior distribution, and in many situations, it is not clear which prior should be used. Several estimators have been developed so far, in which the proposed prior was individually tailored for each property of interest; such is the case, for example, for the entropy, the amount of mutual information, or the correlation between pairs of variables. In this paper we propose a general framework to select priors, valid for arbitrary properties. We first demonstrate that only certain aspects of the prior distribution actually affect the inference process. We then expand the sought prior as a linear combination of a one-dimensional family of indexed priors, each of which is obtained through a maximum entropy approach with constrained mean value of the property under study. In many cases of interest, only one or very few components of the expansion turn out to contribute to the Bayesian estimator, so it is often valid to only keep a single component. The relevant component is selected by the data, so no handcrafted priors are required. We test the performance of this approximation with a few paradigmatic examples, and show that it performs well in comparison to the ad-hoc methods previously proposed in the literature. Our method highlights the connection between Bayesian inference and equilibrium statistical mechanics, since the most relevant component of the expansion can be argued to be the one with the right temperature.

Soft Collinear Effective Theory: An Overview

Year: 2009
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: In this talk I give an overview of soft collinear effective theory (SCET), including a discussion of some recent advances. First, I briefly cover the foundation upon which SCET is built, namely QCD factorization, and review the theoretical framework of SCET. Next, I cover some recent calculations involving SCET. Since there are more interesting results than I can cover, I have picked four that that I find particularly exciting. The first two topics are dynamical threshold enhancements in Drell-Yan and resummation of higgs production at the LHC. Both topics center on the resummation of large Sudakov logarithms, however, for each there is a twist. In the case of threshold enhancements in Drell-Yan, it is partonic, not hadronic logarithms that are summed. In the case of higgs production at the LHC, the twist is that the logarithms are of a time-like scale. The third topic highlighted is electroweak corrections at high energy. In particular the electroweak Sudakov form factor. Finally, I end by discussing generalized event shapes in $e^+e^-$ annihilation.

description: The inducible Di-Cre system was used to delete the putative ubiquitin-conjugating enzyme 13 gene (ubc13) of Plasmodium falciparum to study its role in ubiquitylation and the functional consequence during the parasite asexual blood stage. Deletion resulted in a significant reduction of parasite growth in vitro, reduced ubiquitylation of the Lys63 residue of ubiquitin attached to protein substrates, and an increased sensitivity of the parasite to both the mutagen, methyl methanesulfonate and the antimalarial drug dihydroartemisinin (DHA), but not chloroquine. The parasite was also sensitive to the UBC13 inhibitor NSC697923. The data suggest that this gene does code for an ubiquitin conjugating enzyme responsible for K63 ubiquitylation, which is important in DNA repair pathways as was previously demonstrated in other organisms. The increased parasite sensitivity to DHA in the absence of ubc13 function indicates that DHA may act primarily through this pathway and that inhibitors of UBC13 may both enhance the efficacy of this antimalarial drug and directly inhibit parasite growth.
Revolution in the theatre in the People's Republic of China
Creators: name: Judd, Ellen Ruth
Publisher: name: University of British Columbia
Year: 2011

description: This thesis examines the political transformation of the theatre in the People's Republic of China. Some background to this transformation is provided in a brief survey of the development of the traditional Chinese theatre and of changes that occurred during the twentieth century. The developments in the Red areas before 1949 are given particular attention. The great increase in theatrical activity in the 1950's is described and attention is given to its political aspects. Political problems in the theatre became important in the early 1960's and these are examined in Chapter 4, with particular attention to the case of Wu Han's Peking opera, Hai Jui Dismissed From Office. The denunciation of the "black line" in the theatre during the Cultural Revolution is discussed in the same chapter. The positive response to these political problems is discussed in the following two chapters. Chapter 5 examines the revolution in Peking opera and gives particular attention to the model revolutionary Peking operas on contemporary themes. Chapter 6 discusses the recent developments in creating new forms of theatre suitable for taking theatrical activities to all the Chinese people and, in particular, in ensuring that they reach the most remote settlements in the country. In the conclusion, the developments in the theatre are briefly put into the context of overall developments in Chinese society. Research was limited to reading translations of plays and of Chinese articles, in addition of what other material is available in English. What is shown in this thesis is that the Chinese theatre has undergone a fundamental political transformation— a revolution. In content and in form, a new type of theatre is emerging in China that is designed to serve the people of China and especially the workers, peasants, and soldiers. Problems remain in the theatre, especially in the artistic area, but experimentation and development are continuing on the new political basis established in the Cultural Revolution.

description: The quantum theory of the vector field minimally coupled to the gravity of the de Sitter spacetime is built in a canonical manner starting with a new complete set of quantum modes of given momentum and helicity derived in the moving chart of conformal time. It is shown that the canonical quantization leads to new vector propagators which satisfy similar equations as the propagators derived by Tsamis and Woodard [{\em J.Math.Phys.} {\bf 48} (2007) 052306] but having a different structure. The one-particle operators are also written down pointing out that their properties are similar with those found already in the quantum theory of the scalar, Dirac and Maxwell free fields.

description: The process of uniform supernovae explosions (SNe) is well investigated for all their types. However, observational data suggests that the SNe could be not spherically-symmetric. Modern multi-dimensional simulations of SNe demonstrate development of hydrodynamical instabilities during the explosion phase. But the configuration of a star and inhomogeneities prior to explosion could strongly affect how the SNe develops. In a number of papers on numerical modeling of pair-instability supernovae explosion (PISNe) considered the case when thermonuclear energy in the central region of a massive star is introduced by the series of several hot spots. It leads to the appearance of many fragments of hot matter behind the divergence shock wave. An observable manifestation of this may be the presence of peaks on light curves of gamma-ray burst associated with explosions of massive stars. The physical nature of such inhomogeneities is not evident and the number and size of spots is a conjecture. In this work, we study the possibility of formation of these inhomogeneities at the stage of the core-collapse (CC) in a massive star. To check this assumption, we chose analytic self-similar model of CC and investigated stability of solutions obtained from it with respect to small multidimensional perturbations. It shows there are no conditions where the collapse of a very massive star may remain stable, although, for a less massive star, it is possible. Using obtained relations, we found characteristic features of developing instability, thereby making it possible to estimate the amount and characteristic size of the inhomogeneities.

description: As lesões perfurocontusas por arma de fogo (PAF) apresentam características distintas entre as feridas de entrada e saída, fornecendo informações cruciais para a investigação forense e o tratamento médico. Trauma em região da face, tem sido cada vez mais comum devido a crescente na violência urbana ultimamente. Com isso, as lesões maxilofaciais causadas por arma de fogo têm se tornado rotina nos hospitais de emergência representando um grave problema de saúde pública. O tratamento dos ferimentos penetrantes em face é um desafio em consequência do difícil acesso, comprometimento de estruturas nobres, e risco de fatalidade. Em região de infraorbitária direita causando edema, lesão perfuro-contusa em região malar direita, acuidade visual, motricidade ocular extrínseca de supraversão e infraversão prejudicadas e exoftalmia do olho direito, sendo estabelecido um tratamento em conjunto entre as especialidades de cirurgia e traumatologia bucomaxilofacial e oftalmologia, para remoção do artefato, desbridamento local, remoção de tecido granulomatoso e síntese da conjuntiva ocular e tecidual. Diante do caso clínico apresentado, nota-se que os pacientes com ferimentos por arma de fogo em regiões maxilofaciais, devem ser avaliados por uma equipe multiprofissional, dando ênfase à diminuição das sequelas funcionais e estéticas e às taxas de morbimortalidade. Geralmente maior e mais irregular que a ferida de entrada, com bordas evertidas (viradas para fora). Pode apresentar lacerações e fraturas ósseas, devido à deformação do projétil ao atravessar os tecidos. É de comum pedir uma tomografia para definir uma conduta médica segura e aplicada.

description: We have made a search for common proper motion (CPM) companions to the wide binaries in the solar vicinity. We found that the binary GJ 282AB has a very distant CPM companion (NLTT 18149) at a separation $s=1.09 \arcdeg$. Improved spectral types and radial velocities are obtained, and ages determined for the three components. The Hipparcos trigonometric parallaxes and the new radial velocities and ages turn out to be very similar for the three stars, and provide strong evidence that they form a physical system. At a projected separation of 55733AU from GJ 282AB, NLTT 18149 ranks among the widest physical companions known.

description: We study the stationary dynamics of energy exchange in an ensemble of phase oscillators, coupled through a mean-field mechanical interaction and added with friction and an external periodic excitation. The degree of entrainment between different parts of the ensemble and the external forcing determines three dynamical regimes, each of them characterized by specific rates of energy exchange. Using suitable approximations, we are able to obtain analytical expressions for those rates, which are in satisfactory agreement with results from numerical integration of the equations of motion. In some of the dynamical regimes, the rates of energy exchange show nontrivial dependence on the friction coefficients --in particular, non-monotonic behavior and sign switching. This suggests that, even in this kind of stylized model, power transfer between different parts of the ensemble and to the environment can be manipulated by a convenient choice of the individual oscillator parameters.
title: Idiomatic Expressions and Marital Relationships Over Three Stages of the Family Lifespan
Creators: name: Raynor, Meredith T.
Publisher: name: Old Dominion University Libraries
Year: 2004

description: In interpersonal communication language shared between two people becomes important in the everyday life of relational participants. Even more so, the language shared between married couples is vital because of their "unique relationship". Part of that language involves the symbols, gestures and words called idioms that have specialized meaning for the marital dyad.

This thesis sought to discover what idioms are identified among married couples at three stages of the family lifespan, newlyweds, couples with children and empty nest couples as they seek to maintain a system of "personalized communication" as it relates to their marital satisfaction (Breuss & Pearson, 1993, p. 609). One goal of this study was to determine what patterns may exist between marital couples across the family lifespan. Since previous research seems to indicate an increase followed by a decrease, this study also sought to establish if there is a correlation between the frequency of idiom usage with husband's and or wives' own ratings of marital satisfaction. These questions thus add a new dimension to the study relating to intimacy and private talk among marital dyads.

description: Heterostructures of 2D materials offer a fertile ground to study ion transport and charge storage. Here we employ ab initio molecular dynamics to examine the proton-transfer/diffusion and redox behavior in a water layer confined in the graphene-Ti3C2O2 heterostructure. We find that in comparison with the similar interface of water confined between Ti3C2O2 layers, proton redox rate in the dissimilar interface of graphene-Ti3C2O2 is much higher, owning to the very different interfacial structure as well as the interfacial electric field induced by an electron transfer in the latter. Water molecules in the dissimilar interface of the graphene-Ti3C2O2 heterostructure form a denser hydrogen-bond network with a preferred orientation of water molecules, leading to an increase of proton mobility with proton concentration in the graphene-Ti3C2O2 interface. As the proton concentration further increases, proton mobility deceases, due to increasingly more frequent surface redox events that slow down proton mobility due to binding with surface O atoms. Our work provides important insights into how the dissimilar interface and their associated interfacial structure and properties impact proton transfer and redox in the confined space.

description: Our recently completed one billion particle Via Lactea II simulation of a Milky Way-sized dark matter halo resolves over 50,000 gravitationally bound clumps orbiting today within the virialized region of the main host. About 2,300 of these subhalos have one or more "progenitors" above 1e6 Msun at redshift 11, i.e. massive enough for their gas to have cooled via excitation of H2 and fragmented prior to the epoch of cosmic reionization. We count 4,500 such progenitors: if these were able to convert a fraction of their gas content into very metal-poor stars with a Salpeter initial mass function (IMF), they would be shining today with a visual magnitude M_V=6.7 per solar mass in stars. Assuming a universal baryon fraction, we show that mean star formation efficiencies as low as 0.1% in progenitors below 1e8 Msun would overproduce the abundance of the faint Galatic dwarf spheroidals observed by the Sloan Digital Sky Survey. Star formation at first light must have occurred either with an IMF lacking stars below 0.9 Msun, or was intrinsically very inefficient in small dark matter halos. If the latter, our results may be viewed as another hint of a minimum scale in galaxy formation.

description: The closed-loop supply chain considers forward and reverse logistics. This paper assumes a two-period setting to demonstrate the interaction and effect of periods on the supply chain. In the first period, the manufacturer acts as a leader which produces new products and sells them to the retailer, and the retailer sells them to customers. In the second period, the manufacturer collects used-products to take profit. The objective of this study is to take care of economic, green, and social issues for both manufacturer and retailer in both periods. It presented a flexible solution method in two phases. A numerical example is presented and solved by applying the proposed solution method. Results indicate that the manufacturer as a leader obtains more profit, whereas the retailer is more sensitive towards the discount rate. Moreover, the retailer's profit is more sensitive to the proportion of returned used products than the manufacturer's profit.

description: In this paper we study area-filling curves, i.e. continuous and injective mappings defined on [0,1] whose graph has positive measure. Current literature calls them ``Osgood curves", but their invention is due to H. Lebesgue. Stromberg and Tseng constructed homogeneous area-filling curves and offered an elegant example. We show that an appropriate variant of Knopp's construction attains the same homogeneity result. In Section 4 we discuss briefly the existence of an ``invasive" curve, i.e. a continuous and injective mapping from the half-open interval [0,1[ to the unit square, whose image has measure 1. In the last section we discuss several aspects of the Lance-Thomas curve, connecting it with the other construction due to Stromberg and Tseng.

description: Renormalizable nonanticommutative SYM theories with chiral matter in the adjoint representation of the gauge group have been recently constructed in [arXiv:0901.3094]. In the present paper we focus on the U*(1) case with matter interacting through a cubic superpotential. For a single flavor, in a superspace setup and manifest background covariant approach we perform the complete one-loop renormalization and compute the beta-functions for all couplings appearing in the action. We then generalize the calculation to the case of SU(3) flavor matter with a cubic superpotential viewed as a nontrivial NAC generalization of the ordinary abelian N=4 SYM and its marginal deformations. We find that, as in the ordinary commutative case, the NAC N=4 theory is one-loop finite. We provide general arguments in support of all-loop finiteness. Instead, deforming the superpotential by marginal operators gives rise to beta-functions which are in general non-vanishing. We study the spectrum of fixed points and the RG flows. We find that nonanticommutativity always makes the fixed points unstable.

Domestic unrest and interstate violence : four Middle Eastern states
Creators: name: Bernstein, Irving
Publisher: name: University of British Columbia
Year: 2011

description: In recent years political scientists have shown increasing interest in the relationship between international and intranational politics. One of the problems most frequently dealt with in this area is the relationship between foreign and domestic conflict behaviour. Some of the notions involved are quite venerable and are commonly used in explaining specific events. One such notion is scapegoating, the diversion of popular attention from domestic conflicts to foreign ones. Another such concept posits the strengthening of internal solidarity in the face of external conflict. However, attempts at scientific, systematic examinations of the issue have yielded evidence of only weak relationships at best. In this paper the problem is again approached, though from a different angle than in most other studies. The types of behaviour examined are interstate violence and intrastate political unrest. Measures for each of these variables are developed. Correlations between the measures are then computed for each of four Middle Eastern states: Egypt, Israel, Jordan and Syria. The calculations are made both with and without time lags. The results show no significant relationship between the variables for Israel. For Syria unrest predicts positively and with moderate strength to subsequent interstate violence, while interstate violence predicts moderately and negatively to subsequent unrest. For Egypt and Jordan the variables predict strongly and positively to each other. It is suggested that these differences among the states may be due to differing degrees of freedom of access to political channels in them.

description: In this paper, the localized surface modes in a defective multilayer structure has been investigated. It is shown that the defective multilayer structures can support two different kind of localized modes depending on the position and the thickness of the defect layer. One of these modes is localized at the interface between the multilayer structure and a homogeneous medium (the so-called surface mode) and the other one is localized at the defect layer (defect localized mode). We reveal that the presence of defect layer pushes the dispersion curve of surface modes to the lower or the upper edge of the photonic bandgap depending on the homogeneous medium is a left-handed or right-handed medium (e.g. vacuum), respectively. So, the existence region of the surface modes restricted. Moreover, the effect of defect on the energy flow velocity of the surface modes is discussed.

description: Counterfactual explanations are the de facto standard when tasked with interpreting decisions of (opaque) predictive models. Their generation is often subject to technical and domain-specific constraints that aim to maximise their real-life utility. In addition to considering desiderata pertaining to the counterfactual instance itself, guaranteeing existence of a viable path connecting it with the factual data point has recently gained relevance. While current explainability approaches ensure that the steps of such a journey as well as its destination adhere to selected constraints, they neglect the multiplicity of these counterfactual paths. To address this shortcoming we introduce the novel concept of explanatory multiverse that encompasses all the possible counterfactual journeys. We define it using vector spaces, showing how to navigate, reason about and compare the geometry of counterfactual trajectories found within it. To this end, we overview their spatial properties -- such as affinity, branching, divergence and possible future convergence -- and propose an all-in-one metric, called opportunity potential, to quantify them. Notably, the explanatory process offered by our method grants explainees more agency by allowing them to select counterfactuals not only based on their absolute differences but also according to the properties of their connecting paths. To demonstrate real-life flexibility, benefit and efficacy of explanatory multiverse we propose its graph-based implementation, which we use for qualitative and quantitative evaluation on six tabular and image data sets.

description: The properties of nitrogen doped ZnTe films and in situ formed heterointerfaces to CdTe were investigated using photoelectron spectroscopy and electrical measurements. The p doping of ZnTe with nitrogen is controlled during physical vapor deposition with an additional nitrogen plasma source. The resistivity was determined by four-point measurements and a minimum resistivity of ρ = 0.04 Ω cm was found. The valence band offset of the CdTe/ZnTe interface is EVBO = 0.05 eV.

description: Due to the advent of modern embedded systems and mobile devices with constrained resources, there is a great demand for incredibly efficient deep neural networks for machine learning purposes. There is also a growing concern of privacy and confidentiality of user data within the general public when their data is processed and stored in an external server which has further fueled the need for developing such efficient neural networks for real-time inference on local embedded systems. The scope of our work presented in this paper is limited to image classification using a convolutional neural network. A Convolutional Neural Network (CNN) is a class of Deep Neural Network (DNN) widely used in the analysis of visual images captured by an image sensor, designed to extract information and convert it into meaningful representations for real-time inference of the input data. In this paper, we propose a neoteric variant of deep convolutional neural network architecture to ameliorate the performance of existing CNN architectures for real-time inference on embedded systems. We show that this architecture, dubbed CondenseNeXt, is remarkably efficient in comparison to the baseline neural network architecture, CondenseNet, by reducing trainable parameters and FLOPs required to train the network whilst maintaining a balance between the trained model size of less than 3.0 MB and accuracy trade-off resulting in an unprecedented computational efficiency.

description: The contact formation of thin-film epitaxial CuInSe₂(001) with a physical-vapor-deposited CdS layer is presented in this work. Synchrotron-excited photoelectron spectroscopy was used for this investigation. The epitaxial CuInSe₂ films contain a surface layer of reduced Cu stoichiometry similar to the ordered defect compound CuIn₃Se₅. A valence band offset of 0.79±0.15 eV has been determined for this heterojunction. The comparison to literature data indicates that neither surface orientation nor surface copper content have a major impact on the valence band offset of CuIn₃Se₅, respectively, CuInSe₂ with CdS.

description: The application of Natural Language Processing (NLP) has achieved a high level of relevance in several areas. In the field of software engineering (SE), NLP applications are based on the classification of similar texts (e.g. software requirements), applied in tasks of estimating software effort, selection of human resources, etc. Classifying software requirements has been a complex task, considering the informality and complexity inherent in the texts produced during the software development process. The pre-trained embedding models are shown as a viable alternative when considering the low volume of textual data labeled in the area of software engineering, as well as the lack of quality of these data. Although there is much research around the application of word embedding in several areas, to date, there is no knowledge of studies that have explored its application in the creation of a specific model for the domain of the SE area. Thus, this article presents the proposal for a contextualized embedding model, called BERT_SE, which allows the recognition of specific and relevant terms in the context of SE. The assessment of BERT_SE was performed using the software requirements classification task, demonstrating that this model has an average improvement rate of 13% concerning the BERT_base model, made available by the authors of BERT. The code and pre-trained models are available at https://github.com/elianedb.

description: In this paper, we obtain upper bounds for the critical time $T^*$ of the blow-up for the parabolic-elliptic Patlak-Keller-Segel system on the 2D-Euclidean space. No moment condition or/and entropy condition are required on the initial data; only the usual assumptions of non-negativity and finiteness of the mass is assumed. The result is expressed not only in terms of the supercritical mass $M> 8π$, but also in terms of the {\it shape} of the initial data.

description: The longitudinal resistivity of two dimensional (2D) electrons placed in strong magnetic field is significantly reduced by applied electric field, an effect which is studied in a broad range of magnetic fields and temperatures in GaAs quantum wells with high electron density. The data are found to be in good agreement with theory, considering the strong nonlinearity of the resistivity as result of non-uniform spectral diffusion of the 2D electrons. Inelastic processes limit the diffusion. Comparison with the theory yields the inelastic scattering time of the two dimensional electrons. In the temperature range T=2-10(K) for overlapping Landau levels, the inelastic scattering rate is found to be proportional to T^2, indicating a dominant contribution of the electron-electron scattering to the inelastic relaxation. In a strong magnetic field, the nonlinear resistivity demonstrates scaling behavior, indicating a specific regime of electron heating of well-separated Landau levels. In this regime the inelastic scattering rate is found to be proportional to T^3, suggesting the electron-phonon scattering as the dominant mechanism of the inelastic relaxation.

description: Puberty is a critical period of development accompanied by the maturation of various fundamental systems such as the central nervous system (CNS), immune system, and hypothalamic-pituitary-adrenal axis. The maturation of these systems renders puberty particularly sensitive to stressors, potentially increasing susceptibility to neurodegenerative disorders later in life. The gut microbiome may be a possible mechanism through which pubertal stress exposure could increase vulnerability to neurodegeneration. The gut microbiota communicates with the brain via enteric and autonomic neuroimmune and neuroendocrine pathways referred to as the “gut-brain” axis. Alterations to gut microbiota result in ‘gut dysbiosis’ and may negatively affect this bidirectional communication between the gut and the CNS, potentially influencing the development of neurodegenerative disorders. As such, we hypothesized that altering microbial composition through pubertal lipopolysaccharide (LPS) and antimicrobial treatments could influence behaviours and cellular mechanisms associated with neurodegeneration. The current thesis examined the sex-specific effects of pubertal LPS and antimicrobial treatment on acute cellular mechanisms associated with neurodegeneration (Article 1). Next, we examined the enduring sex-specific effects of pubertal LPS and antimicrobial treatments on behaviours and cellular mechanisms associated with neurodegeneration (Article 2). Lastly, we examined the sex-specific effects of pubertal LPS and antimicrobial treatment on the blood-brain barrier and intestinal permeability, a potential mechanism underlying the effects of the gut on the CNS and the development of neurodegenerative disorders. We also further examined the effects of pubertal LPS and antimicrobial treatment on gross motor coordination, heart rate, and core body temperature through the use of the G2 HR E-Mitter telemetry system (Article 3). Taken together, the current dissertation addresses whether pubertal LPS and antimicrobial treatments can increase vulnerability to neurodegeneration later in life, in a sexually dimorphic manner.

description: The growth of the layered chalcogenide GaSe on cleaved GaAs(110) surfaces was investigated with photoemission and low-energy electron diffraction (LEED). GaSe films grow with their c axis perpendicular to the GaAs(110) surface. LEED patterns after initial film growth are a superposition of rectangular GaAs:Se spots and two hexagonal domains rotated by ±5° with respect to the GaAs ⟨001⟩ axis. At higher film thickness a hexagonal LEED pattern with GaSe〈120〉 ‖ GaAs 〈001〉 is obtained.
