Improving Treatment Adherence and Outcomes in Individuals with Phenylketonuria
Creators: name: Viau, Krista S.
Publisher: name: University of Utah
Year: 2019

description: The objective of this body of research was to (1) survey current self-management skills and treatment knowledge in patients with phenylketonuria (PKU) and (2) evaluate self-efficacy, patient activation, dietary adherence, and blood phenylalanine (Phe) levels in individuals with PKU before and after a 6-month motivational interviewing (MI) intervention. Patients with PKU aged 7-30 years (n=43) completed one of three age-specific self-management questionnaires during standard metabolic clinic appointments and were invited to participate. Separately, patients with PKU aged 7-35 years (n=31) participated in a 6-month intervention including phone-based MI, goal setting, and a monthly summary. Participants completed stage of change (SOC), self-efficacy, patient activation, and food frequency questionnaires online and obtained monthly blood Phe samples. Demographic data were collected from the electronic medical record. We considered p<0.01 as significant when analyzing aim 1 and p<0.05 as significant when analyzing aim 2. Participation in self-management behaviors and treatment knowledge did not increase with age for most measures (p>0.01 for all) with only approximately half of adults meeting clinical recommendations. Higher self-management skills and treatment knowledge were not associated with lower blood Phe levels (R2=0.249, p=0.025), which may reflect the small sample size. Most participants were in the action/maintenance SOC for PKU treatment behaviors during the 6-month MI intervention. Self-efficacy significantly increased from baseline (7.4±1.9) to month 6 (8.6±1.3) among adolescent and adult participants (p=0.002). There was no increase in patient activation (p=0.10) or dietary adherence, though most (n=28/31) reported adherence to medical formula at baseline. Pre-intervention blood Phe slope for all participants (β=0.71) was not significantly different from the intervention slope (β=0.26, p=0.13). Higher baseline SOC (β=-61.6, p=0.005) and increasing self-efficacy (β=-64.5, p<0.001) were associated with a decreased blood Phe slope. Self-management skills were lower than clinically recommended and did not consistently increase with age. We demonstrated a significant increase in self-efficacy with MI and, in turn, higher self-efficacy was associated with a reduction in blood Phe levels. Our results suggest strategies to support self-management and increase motivation for behavior change are necessary. Phone-based MI is feasible with a PKU population has potential to increase confidence to engage in self-management behaviors.
Clausius relation for active particles: what can we learn from fluctuations?

description: Many kinds of active particles, such as bacteria or active colloids, move in a thermostatted fluid by means of self-propulsion. Energy injected by such a non-equilibrium force is eventually dissipated as heat in the thermostat. Since thermal fluctuations are much faster and weaker than self-propulsion forces, they are often neglected, blurring the identification of dissipated heat in theoretical models. For the same reason, some freedom - or arbitrariness - appears when defining entropy production. Recently three different recipes to define heat and entropy production have been proposed for the same model where the role of self-propulsion is played by a Gaussian coloured noise. Here we compare and discuss the relation between such proposals and their physical meaning. One of these proposals takes into account the heat exchanged with a non-equilibrium active bath: such an "active heat" satisfies the original Clausius relation and can be experimentally verified.

description: Bandlimiting and timelimiting operators play a fundamental role in analyzing bandlimited signals that are approximately timelimited (or vice versa). In this paper, we consider a time-frequency (in the discrete Fourier transform (DFT) domain) limiting operator whose eigenvectors are known as the periodic discrete prolate spheroidal sequences (PDPSSs). We establish new nonasymptotic results on the eigenvalue distribution of this operator. As a byproduct, we also characterize the eigenvalue distribution of a set of submatrices of the DFT matrix, which is of independent interest.

description: This study intends to explore the current trends in the field of distance education research catalogued in Web of Science (WoS) database during 1980-2016. Mainly bibliographic description and social network analysis was employed to investigate the structure and patterns of information exchanged within the field of distance education research and also to interpret the interrelationship between keywords indicated in these articles. A total of 500 most cited articles (out of 6,141 relevant to the topic) were reviewed to examine the impact of factors such as journal DOI and keywords on the number of citations that they received. We also identified major trends in distance education literature including variation across publication and citation year, top ranking of institutions and top ranking of published papers based on authors, subject area and co-authorship collaboration between countries. Our results show that the most cited articles are from two institutions of United States and United Kingdom and the most prolific years in terms of number of published articles and citations are 2013.We also found non-significant and very small correlation between the number of citation and DOI number of the journals. Our study serves as a resource for future studies by indicating how trends in distance education research have gradually developed over time and demonstrating the characteristics of the most cited articles in this literature.

description: We present 36 observations of 17 visual binaries of moderate separation (range from 0.15'' to 0.79'') made with the 50 cm Cassegrain telescope of the Jagiellonian University in Cracow. The speckle interferometry technique was combined with modest optical hardware and a standard photometric CCD camera. We used broad-band V,R,I filters without a Risley prism to reduce differential colour refraction, so we performed model analysis to investigate the influence of this effect on the results of measurements. For binary components of spectral type O-F, the difference of three spectral classes between them should bias their relative positions by no more than a couple of tens of milliarcseconds (mas) for moderate zenith distances. The statistical analysis of our results confirmed this conclusion. A cross-spectrum approach was applied to resolve the quadrant ambiguity. Our separations have RMS deviations of 0.012'' and our position angles have RMS deviations of 1.8 deg. Relative photometry in V, R and I filters appeared to be the less accurately determined parameter. We discuss our errors in detail and compare them to other speckle data. This comparison clearly shows the high value of our measurements. We also present an example of the enhancement of image resolution for an extended object of angular size greater than the atmospheric coherence patch using speckle interferometry techniques.

description: In this paper, an improved thermal lattice Boltzmann (LB) model is proposed for simulating liquid-vapor phase change, which is aimed at improving an existing thermal LB model for liquid-vapor phase change [S. Gong and P. Cheng, Int. J. Heat Mass Transfer 55, 4923 (2012)]. First, we emphasize that the replacement of \[{\left( {ρ{c_V}} \right)^{ - 1}}\nabla \cdot \left( {λ\nabla T} \right)\] with \[\nabla \cdot \left( {χ\nabla T} \right)\] is an inappropriate treatment for diffuse interface modeling of liquid-vapor phase change. Furthermore, the error terms ${\partial_{t0}}\left( {Tv} \right) + \nabla \cdot \left( {Tvv} \right)$, which exist in the macroscopic temperature equation recovered from the standard thermal LB equation, are eliminated in the present model through a way that is consistent with the philosophy of the LB method. In addition, the discrete effect of the source term is also eliminated in the present model. Numerical simulations are performed for droplet evaporation and bubble nucleation to validate the capability of the improved model for simulating liquid-vapor phase change. Numerical comparisons show that the aforementioned replacement leads to significant numerical errors and the error terms in the recovered macroscopic temperature equation also result in considerable errors.

Evolution speed in some coupled-spin models

description: We investigate the time evolution of some models with N spins and pairwise couplings, for the case of large N, in order to compare evolution times with "speed limit" minima derived in the literature. Both in a (symmetric) case with couplings of the same strength between each pair and in a case of broken symmetry, the times necessary for evolution to a state in which the simplest initial state has evolved into a nearly orthogonal state are proportional to 1/N, as is the speed limit time. However the coefficient in the broken symmetry case comes much closer to the speed limit value. Introducing a different criterion for evolution speed, based on macroscopic changes in occupation, we find a corresponding enhancement in rates in the asymmetric case as compared to the symmetric case.

description: We give the first detailed study of the arrival time distribution of nucleons in UHECR air showers. We analyze in detail the influence of late arriving particles on the energy determination of the AGASA experiment, as well as how the arrival time distribution changes with distance from shower core. Our calculations are consistent with experimental observations of the AGASA group. Crucial to obtaining agreement, is the correct implementation of the energy loss for low-energy protons. We confirm AGASA's estimation of the error in their energy determination associated with late-arriving particles, assuming primary protons.

description: Differential dijet cross sections are measured in photoproduction in the region of photon virtualities Q^2 < 1 GeV^2 with the H1 detector at the HERA ep collider using an integrated luminosity of 66.6 pb^{-1}. Jets are defined with the inclusive k_T algorithm and a minimum transverse momentum of the leading jet of 25 GeV is required. Dijet cross sections are measured in direct and resolved photon enhanced regions separately. Longitudinal proton momentum fractions up to 0.7 are reached. The data compare well with predictions from Monte Carlo event generators based on leading order QCD and parton showers and with next-to-leading order QCD calculations corrected for hadronisation effects.

description: Recent experimental searches for signatures of Majorana-like excitations in proximitized semiconducting nanowires involve conductance spectroscopy, where the evidence sought after is a robust zero-bias peak (in longer wires) and its characteristic field-dependent splitting (in shorter wires). Although experimental results partially confirm the theoretical predictions, commonly observed discrepancies still include (i) a zero-bias peak that is significantly lower than the predicted value of $2e^2/h$ and (ii) the absence of the expected "Majorana oscillations" of the lowest-energy modes at higher magnetic fields. Here, we investigate how the inevitable presence of a normal drain lead connected to the hybrid wire can affect the conductance spectrum of the hybrid wire. We present numerical results using a one-band model for the proximitized nanowire, where the superconductor is considered to be in the diffusive regime, described by semi-classical Green functions. We show how the presence of the normal drain could (at least partially) account for the observed discrepancies, and we complement this with analytic results providing more insights in the underlying physics.

description: The electron beam-plasma system is ubiquitous in the space plasma environment. Here, using a Darwin particle-in-cell method, the excitation of electrostatic and whistler instabilities by a gyrating electron beam is studied in support of recent laboratory experiments. It is assumed that the total plasma frequency $ω_{pe}$ is larger than the electron cyclotron frequency $Ω_e$. The fast-growing electrostatic beam-mode waves saturate in a few plasma oscillations by slowing down and relaxing the electron beam parallel to the background magnetic field. Upon their saturation, the finite amplitude electrostatic beam-mode waves can resonate with the tail of the background thermal electrons and accelerate them to the beam parallel velocity. The slower-growing whistler waves are excited in primarily two resonance modes: (a) through Landau resonance due to the inverted slope of the beam electrons in the parallel velocity; (b) through cyclotron resonance by scattering electrons to both lower pitch angles and smaller energies. It is demonstrated that, for a field-aligned beam, the whistler instability can be suppressed by the electrostatic instability due to a faster energy transfer rate between beam electrons and the electrostatic waves. Such a competition of growth between whistler and electrostatic waves depends on the ratio of $ω_{pe}/Ω_e$. In terms of wave propagation, beam-generated electrostatic waves are confined to the beam region whereas beam-generated whistler waves transport energy away from the beam.

description: Optimal implementation of quantum gates is crucial for designing a quantum computer. We consider the matrix representation of an arbitrary multiqubit gate. By ordering the basis vectors using the Gray code, we construct the quantum circuit which is optimal in the sense of fully controlled single-qubit gates and yet is equivalent with the multiqubit gate. In the second step of the optimization, superfluous control bits are eliminated, which eventually results in a smaller total number of the elementary gates. In our scheme the number of controlled NOT gates is $O(4^n)$ which coincides with the theoretical lower bound.

description: The possibility that a relevant fraction of the dark matter might be comprised of Primordial Black Holes (PBHs) has been seriously reconsidered after LIGO's detection of a $\sim 30 M_{\odot}$ binary black holes merger. Despite the strong interest in the model, there is a lack of studies on possible cosmological implications and effects on cosmological parameters inference. We investigate correlations with the other standard cosmological parameters using cosmic microwave background observations, finding significant degeneracies, especially with the tilt of the primordial power spectrum and the sound horizon at radiation drag. However, these degeneracies can be greatly reduced with the inclusion of small scale polarization data. We also explore if PBHs as dark matter in simple extensions of the standard $Λ$CDM cosmological model induces extra degeneracies, especially between the additional parameters and the PBH's ones. Finally, we present cosmic microwave background constraints on the fraction of dark matter in PBHs, not only for monochromatic PBH mass distributions but also for popular extended mass distributions. Our results show that extended mass distribution's constraints are tighter, but also that a considerable amount of constraining power comes from the high-$\ell$ polarization data. Moreover, we constrain the shape of such mass distributions in terms of the correspondent constraints on the PBH mass fraction.

description: The unique eclipsing, weak-lined T Tauri star KH 15D has been detected as an X-ray source in a 95.7 ks exposure from the Chandra X-ray Observatory archives. A maximum X-ray luminosity of 1.5 x 10^{29} erg s$^{-1}$ is derived in the 0.5--8 keV band, corresponding to L_{X}/L_bol = 7.5 x 10^{-5}. Comparison with samples of stars of similar effective temperature in NGC 2264 and in the Orion Nebula Cluster shows that this is about an order of magnitude low for a typical star of its mass and age. We argue that the relatively low luminosity cannot be attributed to absorption along the line of sight but implies a real deficiency in X-ray production. Possible causes for this are considered in the context of a recently proposed eccentric binary model for KH 15D. In particular, we note that the visible component rotates rather slowly for a weak-lined T Tauri star and has possibly been pseudosynchronized by tidal interaction with the primary near periastron.

description: Alzheimer’s disease (AD) is defined as an insidious and fatal aging-associated neurodegenerative disorder associated with progressive memory loss and cognitive decline. Among over one hundred attempts to treat these symptoms, despite certain degrees in symptomatic improvement, however, they still failed to reverse or even delay the progressive deterioration in cognitive capability, agitation, depression or psychosis. Recent studies revealed the pivotal role of β-amyloid (Aβ) in AD. The assembly of Aβ into pathological seeds, including toxic oligomers and their subsequent aggregates, constitutes the primary neuropathological hallmark. Unfortunately, there was no clear indication that current nanomaterials exerted any effect on mitigation of Aβ-induced neurotoxicity and elimination of Aβ aggregates in vivo. Therefore, an effective AD therapy requires the development of new therapeutic agents that can modulate Aβ aggregations to reduce the amount of Aβ oligomers and fibrils, as well as accelerate elimination to restore Aβ balance in patient’s brain.

description: Multiphoton interference effects can be measured with a single detector when two input photons are temporally well separated when compared with the dead time of the single-photon avalanche detector. Here we experimentally demonstrate that the Hong-Ou-Mandel interference effect can be observed with a single non-photon-number resolving detector via a time-delayed coincidence measurement of successive electrical signals from the detector. The two-photon interference experiment is performed by utilizing temporally well-separated pairwise weak coherent pulses and the interference fringes are successfully measured with a high visibility in the range of the limited upper bound for the weak coherent photon source.

We separate the mechanism of particle production and the resonance amplification of radiation. The production of photons is a purely quantum effect described in terms of quantum anomalies in recursive formulas. The resonance enhancement is a classical phenomenon of focusing and amplifying beams of photons due to Döppler effect.

We extracted feature vectors of detected faces using the Convolutional Neural Network trained for face identification task, rather than traditional pre-training on emotion recognition problems. In the final pipeline an ensemble of Random Forest classifiers was learned to predict emotion score using available training set. In case when the faces have not been detected, one member of our ensemble extracts features from the whole image. During our experimental study, the proposed approach showed the lowest error rate when compared to other explored techniques. In particular, we achieved 75.4% accuracy on the validation data, which is 20% higher than the handcrafted feature-based baseline. The source code using Keras framework is publicly available.

With high luminosity, 10^{33}cm^{-2}s^{-1}, and high energy, \sqrt{s}=1.4 TeV, such a collider can be built in which a 70 GeV electron (positron) beam in the LHC tunnel is in collision with one of the LHC hadron beams and which operates simultaneously with the LHC. The LHeC makes possible deep-inelastic lepton-hadron (ep, eD and eA) scattering for momentum transfers Q^2 beyond 10^6 GeV^2 and for Bjorken x down to the 10^{-6}. New sensitivity to the existence of new states of matter, primarily in the lepton-quark sector and in dense partonic systems, is achieved. The precision possible with an electron-hadron experiment brings in addition crucial accuracy in the determination of hadron structure, as described in Quantum Chromodynamics, and of parton dynamics at the TeV energy scale. The LHeC thus complements the proton-proton and ion programmes, adds substantial new discovery potential to them, and is important for a full understanding of physics in the LHC energy range.

description: The Jagiellonian Positron Emission Tomograph (J-PET) is the first PET built from plastic scintillators. J-PET prototype consists of 192 detection modules arranged axially in three layers forming a cylindrical diagnostic chamber with the inner diameter of 85 cm and the axial field-of-view of 50 cm. An axial arrangement of long strips of plastic scintillators, their small light attenuation, superior timing properties, and relative ease of the increase of the axial field-of-view opens promising perspectives for the cost effective construction of the whole-body PET scanner, as well as construction of MR and CT compatible PET inserts. Present status of the development of the J-PET tomograph will be presented and discussed.

description: We present imaging and spectral studies of the supernova remnant (SNR) Sagittarius (Sgr) A East from deep observations with the {\it Chandra X-Ray Observatory}. The spatially-resolved spectral analysis of Sgr A East reveals the presence of a two-temperature thermal plasma ($kT$ $\sim$ 1 keV and 5 keV) near the center of the SNR. The central region is dominated by emission from highly-ionized Fe-rich ejecta. We estimate a conservative upper limit on the total Fe ejecta mass of the SNR, M$_{Fe}$ $

description: Das Promotionswesen in Deutschland ist insgesamt gut erforscht und umfasst zahlreiche Fachbereiche. Viele, fächerübergreifende Studien beschäftigen sich mit dieser Thematik. Das Fach De-signwissenschaft, als eine noch recht junge Disziplin, ist bisher noch nicht in solchen Studien enthalten. Das Ziel dieser Forschung ist die Analyse des Promotionswesens in der Designwissenschaft in Deutschland hinsichtlich der Rahmenbedingungen und Perspektiven für die Promotionskultur. Dazu werden folgende Forschungsfragen gestellt: „Wie wird in der Designwissenschaft promoviert?“ und „Welche Vorstellungen und Erwartungen werden an eine Promotion in diesem Fach formuliert?“. Um die Forschungsfragen zu beantworten, wurden zunächst 22 Promotionsordnungen von zehn Universitäten und neun Kunsthochschulen analysiert, an denen eine Promotion in der Designwissenschaft möglich ist. Basierend auf diesen Ergebnissen wurden zwei Studien im Mixed-Method-Forschungsdesign durchgeführt, in dessen Rahmen Professor(inn)en und Dokto-rand(inn)en mittels Gruppen- und Expert(inn)eninterviews sowie schriftlich befragt wurden. Die Analyse der Promotionsordnungen ergab eine Übersicht der derzeit bestehenden Promotionszugangsmöglichkeiten. Insbesondere werden hinsichtlich der Rahmenbedingungen Wege zur Promotion und unterschiedliche Promotionstypen in der Designwissenschaft dargestellt. Die Professor(inn)en- und Doktorand(inn)enbefragungen haben gezeigt, dass das Promotionswesen in der Designwissenschaft in einigen Punkten bereits gut ausgestaltet, jedoch insbesondere bezüglich promotionsfördernder Maßnahmen noch ausbaufähig ist. Aus den Befragungsergeb-nissen wurden Anregungen für die Promotionspraxis abgeleitet.

description: "F-free" CeOBiS$_2$ single crystals have successfully grown, thoroughly eliminating a concern about F-contamination by using a high-purity CsCl flux. The obtained crystals have a plate-like shape with a size of 1.0-3.0 mm in the well-developed plane. Single crystal X-ray structural analysis clearly revealed that the CeOBiS$_2$ crystallizes with a space group $P4/nmm$ (with lattice parameters of $a$ = 4.0189(6) Å, $c$ = 13.573(2) Å). The bond valence sum estimation and X-ray photoelectron spectroscopy analysis showed that the chemical state of Ce was in the mixed valence of Ce$^{3+}$ and Ce$^{4+}$. The single crystals show superconductivity with zero resistivity at $\sim$1.3 K. This is the first conclusive evidence of superconductivity driven by Ce valence fluctuation in surely non-doped CeOBiS$_2$. The superconducting transition temperature was enhanced up to $\sim$3.8 K by applying hydrostatic pressure.

description: Light sterile neutrinos can be probed in a number of ways, including electroweak decays, cosmology and neutrino oscillation experiments. At long-baseline experiments, the neutral-current data is directly sensitive to the presence of light sterile neutrinos: once the active neutrinos have oscillated into a sterile state, a depletion in the neutral-current data sample is expected since they do not interact with the $Z$ boson. This channel offers a direct avenue to probe the mixing between a sterile neutrino and the tau neutrino, which remains largely unconstrained by current data. In this work, we study the potential of the DUNE experiment to constrain the mixing angle which parametrizes this mixing, $θ_{34}$, through the observation of neutral-current events at the far detector. We find that DUNE will be able to improve significantly over current constraints thanks to its large statistics and excellent discrimination between neutral- and charged-current events.

description: We have continued our investigation of the charge-exchange reaction K^+ Xe --> K^0 p Xe' in the bubble chamber DIANA. In agreement with our previous results based on part of the present statistics, formation of a narrow p K^0 resonance with mass of 1537+-2 MeV/c^2 is observed in the elementary transition K^+ n --> K^0 p on a neutron bound in the Xenon nucleus. Visible width of the peak is consistent with being entirely due to instrumental resolution and allows to place an upper limit on its intrinsic width: Γ< 9 MeV/c^2. A more precise estimate of the resonance intrinsic width, Γ= 0.36+-0.11 MeV/c^2, is obtained from the ratio between the numbers of resonant and non-resonant charge-exchange events. The signal is observed in a restricted interval of incident K^+ momentum, that is consistent with smearing of a narrow p K^0 resonance by Fermi motion of the target neutron. Statistical significance of the signal is some 7.3, 5.3, and 4.3 standard deviations for the estimators S/sqrt{B}, S/sqrt{S+B}, and S/sqrt{S+2B}, respectively. This observation confirms and reinforces our earlier results, and offers strong evidence for formation of a pentaquark baryon with positive strangeness in the charge-exchange reaction K^+ n --> K^0 p on a bound neutron.
