description: Abstract Assessing perianal disease activity is important for the treatment and prognosis of Crohn?s disease (CD) patients. Transperineal ultrasound in a simple, painless, non invasive method to define the morphological features of fistulas and abscess and probably also to evaluate activity. TPUS results could be optimized using e.v. contrast enhancement and sonoelastography. Purpose The aim of this study was to determine the agreement of clinical scores, the Fistula Drainage Assessment (FDA) and Perianal Disease Activity Index (PDAI), pelvic MRI and transperineal ultrasound (TPUS) with contrast enhancement (CEUS) ad elastography, in defining the activity of perianal CD. Methods Thirty consecutive patients with CD and perianal fistulae underwent clinical, FDA and PDAI; only 28 underwent TPUS evaluation (traditional, with e.v. contrast enhancement and with elastography), and 23 pelvic MRI. Results MRI finding correlate with both PDAI (p=0.02) and PDAI (p=0.059) in defining active/inactive perianal fistulas. CEUS parameters show great variability and poor concordance with clinical index and MRI. Elastography TPUS correlate with FDA (p=0.039) but not with PDAI. Conclusions MRI still represents the gold standard in defining perianal CD activity. TPUS is an emerging technique in the study of perianal CD, with promising results in association with elastography. CEUS does not seem to provide additional advantages.

description: Planets orbiting post-common envelope binaries provide fundamental information on planet formation and evolution. We searched for such planets in NN Ser ab, an eclipsing short-period binary that shows long-term eclipse time variations. Using published, reanalysed, and new mid-eclipse times of NN Ser ab obtained between 1988 and 2010, we find excellent agreement with the light-travel-time effect by two additional bodies superposed on the linear ephemeris of the binary. Our multi-parameter fits accompanied by N-body simulations yield a best fit for the objects NN Ser (ab)c and d locked in a 2:1 mean motion resonance, with orbital periods P_c=15.5 yrs and P_d=7.7 yrs, masses M_c sin i_c = 6.9 M_Jup and M_d sin i_d = 2.2 M_Jup, and eccentricities e_c=0 and e_d=0.20. A secondary chi**2 minimum corresponds to an alternative solution with a period ratio of 5:2. We estimate that the progenitor binary consisted of an A star with ~2 M_Sun and the present M dwarf secondary at an orbital separation of ~1.5 AU. The survival of two planets through the common-envelope phase that created the present white dwarf requires fine tuning between the gravitational force and the drag force experienced by them in the expanding envelope. The alternative is a second-generation origin in a circumbinary disk created at the end of this phase. In that case, the planets would be extremely young with ages not exceeding the cooling age of the white dwarf of 10**6 yrs.

STRUCTURAL STUDIES ON THE REGULATORY DOMAIN OF THREE HCN (HYPERPOLARIZATION-ACTIVATED CYCLIC NUCLEOTIDE-GATED) CHANNEL ISOFORMS

description: Hyperpolarization-activated cyclic nucleotide gated (HCN) chan- nels underlie the If /Ih cation currents that control pacemaker activity in heart and brain. HCN channels are dually ac- tivated by membrane hyperpolarization and binding of cAMP to their cyclic nucleotide binding domain (CNBD). Binding of cAMP shifts the activation curve of HCN2 and HCN4 by 17 mV, but that of HCN1 by only 2-4 mV. Tetramerization of the CNBD is seemingly part of the cAMP-induced allosteric con- formational changes that increase the open probability of the channel pore. We have obtained the crystal structures of the CNBD of the three isoforms, but the analysis revealed a very conserved structure between HCN1 versus HCN2 and HCN4, except for a loop of ?-roll, previously shown to regulate the binding affinity of HCN4. We measured the binding affin- ity of the CNBD for the cAMP and the different propensity of the regulatory domain to tetramerize in absence or presence of the ligand. We confirm that tetramerization is the primary ef- fect of cAMP binding, and the first step in the transmission of this signal, that eventually removes the inhibition imposed by the CNBD on the channel. Accordingly, cAMP- binding releases HCN2 and HCN4 from inhibition, but has little or no effect on HCN1. Our data demonstrate that in HCN1 the CNBD is already tetrameric at basal cAMP concentrations contrary to HCN2 and HCN4. HCN1 shows this peculiar behavior despite its cAMP- binding affinity is in the same range of the affinity found in HCN2 and HCN4. This can be explained by two different 3 affinity states (high and low). HCN1 is, at low cAMP concen- trations, already switched to the low affinity conformation, while the high affinity state is not measurable because the binding site is already occupied. Our results offer a logical explanation for the behavior of HCN1 and an experimental support to the leading hypothesis that ligand-induced tetramerization removes tonic inhibition from the pore. In addition, some more inter- esting information arose from the crystal structure, highlighting an additional electron density close to the tetramerization inter- face of the proteins. We investigated a range of molecules that could bind the proteins in that pocket and potentially alter the functionality of the channel.

description: Through the exact solution of a two-electron system interacting with a monochromatic laser we prove that all adiabatic density functionals within time-dependent density-functional theory are not able to discern between resonant and non-resonant (detuned) Rabi oscillations. This is rationalized in terms of a fictitious dynamical exchange-correlation (xc) detuning of the resonance while the laser is acting. The non-linear dynamics of the Kohn-Sham system shows the characteristic features of detuned Rabi oscillations even if the exact resonant frequency is used. We identify the source of this error in a contribution from the xc-functional to the non-linear equations describing the electron dynamics in an effective two-level system. The constraint of preventing the detuning introduces a new strong condition to be satisfied by approximate xc-functionals.

Exploring the relationship between national parks and gateway communities through residents' perceptions
Creators: name: Hu, Fangbing
Publisher: name: University of British Columbia
Year: 2023

description: Gateway communities are crucial to national park management, and the impacts of national parks on gateway communities are mostly related to tourism. Residents' perceptions of tourism could reveal people's interactions with national parks, thereby affecting management effectiveness. However, residents' perceptions of tourism impacts are rarely emphasized in national park gateway communities in North America and the variables associated with local support haven't been completely identified. This thesis explored residents' perceptions and examined the criteria used by previous scholars to identify the impact factors and investigate local support for tourism. A survey-based questionnaire instrument collected residents' perceptions (n = 790) in the gateway communities of the two most-visited national parks in North America. This study (Chapter 3) found that the main issues in the gateway communities at Banff National Park were noise pollution, a lack of infrastructure, visitor environmental education, and environmental issues related to water, air and garbage disposal. Residents' perceived impacts of tourism development were primarily reflected in community life, natural environment, cultural development, quality of life, and economic development, and the intermediate gateway community residents perceived most impacts from tourism. The local support by studied gateway communities of BNP was associated with the natural environment, cultural development and quality of life factors identified from exploratory factor analysis, and the core GC residents were most supportive. Further, this study (Chapter 4) found a discrepancy between the expected level of park development and community status, and corresponding management measures need to be taken. Tourism development mainly caused environmental and social-cultural issues rather than economic issues. It was also found that support for tourism (ST) was highly associated with community participation (CP), the living environment (LE), trust in tourism agencies (TT), tourism benefits (TB), and community satisfaction (CS). Moreover, this study provided recommendations for both local authorities to better manage the gateway communities by prioritizing environment management, optimizing the use of environmental resources, and obtaining residents’ support by the positive aspects identified in this study. Aside from that, the study recommended that park managers provide economic benefits to local stakeholders and environmental education to visitors. Lastly, some limitations were addressed.

title: Adult Attachment Styles and Their Correlation with Marital Adjustment and Divorce
Creators: name: Jones, Cheryl
Publisher: name: Utah State University
Year: 2004

description: The theory of attachment is a fairly recent approach to studying the relationship between romantic partners. Attachment theory was originally studied to explain the needs and behaviors between infants and their primary caregivers. The attachment style that infants have with their primary caregiver characterizes them throughout their entire lives. Three different styles of attachment have been described: secure, avoidant, and ambivalent. Secure individuals find it easy to get close to others. Avoidant individuals are nervous when people get too close. Ambivalent individuals want to get very close to others and are fearful of abandonment.
Various research studies suggest that attachment styles formed in infancy carry over into adulthood and have an effect on their internal working model. This can affect the level of marital adjustment that is experienced. Thus, the ability to be close to another individual in adulthood is influenced by very early attachment relationships. Attachment styles may effect levels of conflict, communication, and adjustment, which may in tum affect marital status. Attachment processes in adults may play an important part in couple and family therapy.
The purpose of this research was to discover if attachment styles in adults relate to marital status. The sample consisted of 196 low income mothers of one year old infants. The marital status of young mothers was compared to their adult attachment styles as measured by the Attachment Style Scales (ASS) questionnaire (Becker & Billings, 1997). The results were statistically significant that married mothers had attachment styles that were more secure (t = 3.10, p < .003) than divorced or separated mothers. Furthermore, ambivalent style was more common than avoidant style of insecure attachment among divorced/separated mothers. This research helps to suggest that attachment styles in adulthood influence romantic relationships and that it is a beneficial perspective in Marriage and Family Therapy.

description: We introduce a new approach to constructing networks with realistic features. Our method, in spite of its conceptual simplicity (it has only two parameters) is capable of generating a wide variety of network types with prescribed statistical properties, e.g., with degree- or clustering coefficient distributions of various, very different forms. In turn, these graphs can be used to test hypotheses, or, as models of actual data. The method is based on a mapping between suitably chosen singular measures defined on the unit square and sparse infinite networks. Such a mapping has the great potential of allowing for graph theoretical results for a variety of network topologies. The main idea of our approach is to go to the infinite limit of the singular measure and the size of the corresponding graph simultaneously. A very unique feature of this construction is that the complexity of the generated network is increasing with the size. We present analytic expressions derived from the parameters of the -- to be iterated-- initial generating measure for such major characteristics of graphs as their degree, clustering coefficient and assortativity coefficient distributions. The optimal parameters of the generating measure are determined from a simple simulated annealing process. Thus, the present work provides a tool for researchers from a variety of fields (such as biology, computer science, biology, or complex systems) enabling them to create a versatile model of their network data.

description: We present a conceptual design for an active neutron veto, based on boron-loaded liquid scintillator, for use in direct-detection dark matter experiments. The simulated efficiency of a 1 meter thick veto, after including the effects of neutron captures in the inner detector and inefficiencies due to feed-throughs into the veto, is greater than 99.5% for background events produced by radiogenic neutrons, while the background due to externally produced cosmogenic neutrons is reduced by more than 95%. The ability of the veto to both significantly suppress, and provide in situ measurements of, these two dominant sources of background would make the next generation of dark matter experiments much more robust, and dramatically improve the credibility of a dark matter detection claim based on the observation of a few recoil events. The veto would also allow direct extrapolation between the background-free operation of a small detector and the physics reach of a larger detector of similar construction.

description: We derive a coordinate-independent formulation of the post-1-Newtonian approximation to general relativity. This formulation is a generalization of the Newton-Cartan geometric formulation of Newtonian gravity. It involves several fields and a connection, but no spacetime metric at the fundamental level. We show that the usual coordinate-dependent equations of post-Newtonian gravity are recovered when one specializes to asymptotically flat spacetimes and to appropriate classes of coordinates.

Si vuole inoltre riflettere su quale ruolo possa assumere un docente nell’ottica di includere un materiale didattico apparentemente esclusivo. Questo lavoro ha come temi principali la differenziazione e l’inclusione trattati all’interno di una sezione in cui è presente un’allieva con disabilità verbale. Il percorso si basa sul metodo induttivo poiché permette di svolgere delle interpretazioni personali sui comportamenti degli allievi in rapporto al materiale di CAA. Il focus della ricerca verte sul ruolo che un materiale didattico speciale può assumere tra i bambini della Scuola dell’Infanzia indipendentemente dall’età. L’indagine porta a compiere delle osservazioni in occasioni abituali per il bambino, sia nel gioco libero, sia in attività strutturate, con l’aggiunta di materiali specifici nati per agevolare la comunicazione della bambina disabile. Attraverso osservazioni passive e partecipanti si possono cogliere atteggiamenti e scambi verbali e non verbali che hanno permesso di percepire un’evoluzione nei bambini. Il materiale utilizzato in CAA può essere un buon mediatore didattico sia per attivare nuove competenze, sia per differenziare maggiormente le attività didattiche aiutando indirettamente nelle difficoltà e potenziando in diverse situazioni l’autonomia del bambino.

description: In supercooled liquids, vitrification generally suppresses crystallization. Yet some glasses can still crystallize despite the arrest of diffusive motion. This ill-understood process may limit the stability of glasses, but its microscopic mechanism is not yet known. Here we present extensive computer simulations addressing the crystallization of monodisperse hard-sphere glasses at constant volume (as in a colloid experiment). Multiple crystalline patches appear without particles having to diffuse more than one diameter. As these patches grow, the mobility in neighbouring areas is enhanced, creating dynamic heterogeneity with positive feedback. The future crystallization pattern cannot be predicted from the coordinates alone: crystallization proceeds by a sequence of stochastic micro-nucleation events, correlated in space by emergent dynamic heterogeneity.

description: A finite Larmor radius approximation is derived from the classical Vlasov equation, in the limit of large (and uniform) external magnetic field. We also provide an heuristic derivation of the electroneutrality equation in the finite Larmor radius setting. Existence and uniqueness of a solution is proven in the stationary frame for solutions depending only on the direction parallel to the magnetic field and factorizing in the velocity variables.
title: Genetic Analysis of Acetone Carboxylase in Azotobacter vinelandii
Creators: name: Gardner, Jessica
Publisher: name: Utah State University

description: Acetone carboxylase, an inducible multimeric enzyme found in several bacteria, catalyzes the carboxylation of acetone to produce acetoacetate. This is an important reaction for the bacteria because, upon addition of coenzyme A, the acetoacetate can be converted to acetyl-CoA, a common metabolic intermediate. Azotobacter vinelandii, one of the bacteria that produces acetone carboxylase, has two different genes encoding this enzyme. We knocked out the first of these by disrupting it with a kanamycin cassette to help us understand the function of the second gene. Knocking out the gene will also make possible the use of site-directed mutagenesis to further study the enzyme.

description: Superstatistics permits the calculation of the Feynman propagator of a relativistic particle in a novel way from a superstatistical average over non-relativistic single-particle paths. We illustrate this for the Klein-Gordon particle in the Feshbach-Villars representation, and for the Dirac particle in the Schroedinger-Dirac representation. As a byproduct we recover the worldline representation of Klein-Gordon and Dirac propagators, and discuss the role of the smearing distributions in fixing the reparametrization freedom. The emergent relativity picture that follows from our approach together with a novel representation of the Lorentz group for the Feshbach-Villars particle are also discussed.

Joint scaling laws in functional and evolutionary categories in prokaryotic genomes

description: We propose and study a class-expansion/innovation/loss model of genome evolution taking into account biological roles of genes and their constituent domains. In our model numbers of genes in different functional categories are coupled to each other. For example, an increase in the number of metabolic enzymes in a genome is usually accompanied by addition of new transcription factors regulating these enzymes. Such coupling can be thought of as a proportional "recipe" for genome composition of the type "a spoonful of sugar for each egg yolk". The model jointly reproduces two known empirical laws: the distribution of family sizes and the nonlinear scaling of the number of genes in certain functional categories (e.g. transcription factors) with genome size. In addition, it allows us to derive a novel relation between the exponents characterising these two scaling laws, establishing a direct quantitative connection between evolutionary and functional categories. It predicts that functional categories that grow faster-than-linearly with genome size to be characterised by flatter-than-average family size distributions. This relation is confirmed by our bioinformatics analysis of prokaryotic genomes. This proves that the joint quantitative trends of functional and evolutionary classes can be understood in terms of evolutionary growth with proportional recipes.

Constraint on dark matter annihilation with dark star formation using Fermi extragalactic diffuse gamma-ray background data

description: It has been proposed that during the formation of the first generation stars there might be a "dark star" phase in which the power of the star comes from dark matter annihilation. The adiabatic contraction process to form the dark star would result in a highly concentrated density profile of the host halo at the same time, which may give enhanced indirect detection signals of dark matter. In this work we investigate the extragalactic $γ$-ray background from dark matter annihilation with such a dark star formation scenario, and employ the isotropic $γ$-ray data from Fermi-LAT to constrain the model parameters of dark matter. The results suffer from large uncertainties of both the formation rate of the first generation stars and the subsequent evolution effects of the host halos of the dark stars. We find, in the most optimistic case for $γ$-ray production via dark matter annihilation, the expected extragalactic $γ$-ray flux will be enhanced by 1-2 orders of magnitude. In such a case, the annihilation cross section of the supersymmetric dark matter can be constrained to the thermal production level, and the leptonic dark matter model which is proposed to explain the positron/electron excesses can be well excluded. Conversely, if the positron/electron excesses are of a dark matter annihilation origin, then the early Universe environment is such that no dark star can form.

description: This work developed a numerical procedure for a system of partial differential equations (PDEs) describing the propagation of solitons in ideal optical fibers. The validation of the procedure was implemented from the numerical comparison between the known analytical solutions of the PDEs system and those obtained by using the numerical procedure developed. It was discovered that the procedure, based on the finite difference method and relaxation Gauss-Seidel method, was adequate in describing the propagation of soliton waves in ideals optical fibers.

description: The coupled-channels density-matrix technique for nuclear reaction dynamics, which is based on the Liouville-von Neumann equation with Lindblad dissipative terms, is developed with the inclusion of full angular momentum couplings. It allows a quantitative study of the role and importance of quantum decoherence in nuclear scattering. Formulae of asymptotic observables that can reveal effects of quantum decoherence are given. A method for extracting energy-resolved scattering information from the time-dependent density matrix is introduced. As an example, model calculations are carried out for the low-energy collision of the $^{16}$O projectile on the $^{154}$Sm target.

description: It all began with a string of music, a melody. It seemed fitting for strings and so it was decided to begin a work for strings. The first movement was intended to stand alone, but once the idea to complete a string quartet was born it progressed from there. It is easy to see a progression in the compositional style of Juan-Carlos Mackey from the beginning to the end, and it is somehow fitting for the piece as well.
Nonlinear model predictive control for the suppression of the COVID-19 pandemic based on an agent-based model
Creators: name: Niu, Yue
Publisher: name: University of British Columbia
Year: 2022

description: In this thesis, Nonlinear Model Predictive Control (NMPC) is used in conjunction with an Agent-Based Model (ABM) in order to find optimal control measures in containing the Coronavirus Disease 2019 (COVID-19) pandemic. The control measures are designed so that the hospital can have some level of available beds and at the same time the economy is minimally adversely impacted by the restrictive measures imposed by the government. To achieve this goal, it is crucial to predict the effects of control measures and tuning them adaptively. The ABM and NMPC are presented as solutions to these issues. The ABM is capable of predicting how control measures affect people's disease status by using various traits of individual agents such as symptom levels, latent periods (i.e., the time during which people are infected but not infectious), infectious periods (i.e., the time during which people remain infectious), and mobilities. Based on these predictions, NMPC can be employed to tune the control measures adaptively by taking into account the upcoming changes. Computer simulations demonstrate the superiority of NMPC in keeping the number of hospitalized patients below the hospital bed threshold with the least economic cost compared to on-off control and Proportional (P) control using the same ABM. According to the 100-triple simulations among NMPC, on-off control, and P-control, NMPC is shown to be the best control technique for 95 out of 100 times.
Extended Detailed Balance for Systems with Irreversible Reactions

description: The principle of detailed balance states that in equilibrium each elementary process is equilibrated by its reverse process. For many real physico-chemical complex systems (e.g. homogeneous combustion, heterogeneous catalytic oxidation, most enzyme reactions etc), detailed mechanisms include both reversible and irreversible reactions. In this case, the principle of detailed balance cannot be applied directly. We represent irreversible reactions as limits of reversible steps and obtain the principle of detailed balance for complex mechanisms with some irreversible elementary processes. We proved two consequences of the detailed balance for these mechanisms: the structural condition and the algebraic condition that form together the extended form of detailed balance. The algebraic condition is the principle of detailed balance for the reversible part. The structural condition is: the convex hull of the stoichiometric vectors of the irreversible reactions has empty intersection with the linear span of the stoichiometric vectors of the reversible reaction. Physically, this means that the irreversible reactions cannot be included in oriented pathways. The systems with the extended form of detailed balance are also the limits of the reversible systems with detailed balance when some of the equilibrium concentrations (or activities) tend to zero. Surprisingly, the structure of the limit reaction mechanism crucially depends on the relative speeds of this tendency to zero.

title: The Adverse Health Effects of Trans Fatty Acids, and Implications for Public Policy
Creators: name: Atkin, Jonathan D.
Publisher: name: Utah State University
Year: 2005

description: Subject: Trans fatty acids (TFAs) are produced either by the process of bacterial hydrogenation in the stomachs of ruminant animals, or the commercial method called industrial hydrogenation. The latter began early in the 20th century based on purported health benefits and lowered costs. Alarming results from scientific studies in the early 1990's began to raise questions about whether TFAs should be regulated in our food supply.
Findings/Statistics: Scientific research initially discovered that TFAs raise the LDL/HDL ratio, thereby increasing the risk of coronary heart disease (CHD). Recent large, prospective, population-based studies have indicated a 25% increased risk of ischemic heart disease (IHD) from an increased TFA consumption equaling 2% of total energy intake (or 2E%). Gram for gram, the risk of IHD from TFAs is estimated to be 2.5 to 10 times greater than from saturated fat. More research is needed to support claims the TFAs play harmful roles in poor fetal and infant growth, and in the development of cancer, type 2 diabetes, and allergies. The effects of newly adopted TFA labeling regulations on the steady, average U.S. consumption remains to be seen. Danish regulation of TFAs limits production, and has been associated with a lower national average intake and IHD death rate.
Applications/Conclusions: Considering the indisputable evidence linking TFA intake to IHD risk, the question must be posed whether the U.S. regulations requiring labeling of TFA content are adequate. Special consideration is needed to determine the most effective ways to reduce TFA content in foods as well as the average U.S. consumption.
Measurement of the Polarization of W Bosons with Large Transverse Momenta in W+Jets Events at the LHC
Creators: name: CMS Collaboration
Publisher: name: arXiv
Year: 2011
Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: A first measurement of the polarization of W bosons with large transverse momenta in pp collisions is presented. The measurement is based on 36 inverse picobarns of data recorded at sqrt(s) = 7 TeV by the CMS detector at the LHC. The left-handed, right-handed and longitudinal polarization fractions (f_L, f_R, f_0) of W bosons with transverse momenta larger than 50 GeV are determined using decays to both electrons and muons. The muon final state yields the most precise measurement, (f_L - f_R) = 0.240 +/- 0.036 (stat.) +/- 0.031 (syst.) and f_0 = 0.183 +/- 0.087 (stat.) +/- 0.123 (syst.) for negatively charged W bosons, and (f_L - f_R) = 0.310 +/- 0.036 (stat.) +/- 0.017 (syst.) and f_0 = 0.171 +/- 0.085 (stat.) +/- 0.099 (syst.) for positively charged W bosons. This establishes, for the first time, that W bosons produced in pp collisions with large transverse momenta are predominantly left-handed, as expected in the standard model.

description: In this preregistered study, we investigated the type of knowledge people use to discriminate between true and fake news by asking participants (N = 327 Prolific users residing in the United States) to rate the veracity of different news headlines and indicate what decision strategy they used to make each rating (guess, intuition, familiarity, prior knowledge, rule, or other). We found that participants discriminated well between true and fake news headlines, but they predominantly chose decision strategies that suggested they were using tacit knowledge (knowledge that is not easily articulated). For example, guess and intuition were chosen 63% of the time, and participants’ discrimination was good even when they claimed to be guessing. The fact that tacit knowledge formed the dominant basis of participants’ discriminative ability speaks to the types of interventions that are likely to be successful in improving this skill.
