description: The past few years have seen a surge of interest in the field of probabilistic logic learning and statistical relational learning. In this endeavor, many probabilistic logics have been developed. ProbLog is a recent probabilistic extension of Prolog motivated by the mining of large biological networks. In ProbLog, facts can be labeled with probabilities. These facts are treated as mutually independent random variables that indicate whether these facts belong to a randomly sampled program. Different kinds of queries can be posed to ProbLog programs. We introduce algorithms that allow the efficient execution of these queries, discuss their implementation on top of the YAP-Prolog system, and evaluate their performance in the context of large networks of biological entities.

The nigrostriatal dopamine system in the leucine-rich repeat kinase 2 G2019S knock-in mouse model of Parkinson's disease
Creators: name: Paschall, Sarah Afton
Publisher: name: University of British Columbia
Year: 2016

description: Mutations on the leucine-rich repeat kinase 2 (LRRK2) gene are the most common variants responsible for idiopathic Parkinson’s disease (PD). Historically, PD is thought of as a late-stage neurodegenerative disease resulting from the loss of dopaminergic neurons in the substantia nigra pars compacta with the presence of Lewy pathology. Current treatments focus on the dopaminergic aspect of this disease, without addressing or successfully halting the underlying causes of this disease. The LRRK2 G2019S mutation is the single most common genetic risk factor for Parkinson’s disease and leads to increased kinase activity with subtle effects on the timing of nigrostriatal dopaminergic transmission. Here, using a genetically faithful G2019S knock-in (GKI) mouse model at multiple age points, although no differences were seen in monoamine, glutamate, or GABA release by in vivo microdialysis of the dorsolateral striatum, more temporally sensitive investigation revealed subtle release augmentation in mutants. Using fast-scan cyclic voltammetry to examine dopamine release and reuptake on a millisecond timescale in acute striatal slices at early (<3 months) and later age points (~12 months), alterations in dopamine release were observed with repeated stimulation and increased decay constant in mutants. In GKI mice dopamine release is augmented and responds differently across age points to pharmacological D2 receptor agonism and dopamine transporter (DAT) inhibition. LRRK2 is thought to be involved in synaptic vesicle storage and recycling and GKI mutation in mice leads to augmented dopamine release from an early age that is not attenuated by DAT inhibition, indicating other mechanisms (e.g. altered release / vesicle cycling) are affected and play a role in this alteration from early stages (<3 months, potentially earlier) in response to this mutation. Elucidation of the function of LRRK2 and the deleterious effects caused by the G2019S mutation will help target neuroprotective therapies to delay or halt disease progression.

description: It has now been possible to prepare chain of ions in an entangled state and thus question arises --- how the optical properties of a chain of entangled ions differ from say a chain of independent particles. We investigate nonlinear optical processes in such chains. We explicitly demonstrate the possibility of entanglement produced super Raman scattering. Our results in contrast to Dicke's work on superradiance are applicable to stimulated processes and are thus free from the standard complications of multimode quantum electrodynamics. Our results suggest the possibility of similar enhancement factors in other nonlinear processes like four wave mixing.

Self-localization of a small number of Bose particles in a superfluid Fermi system

Subjects: subject: Quantum Gases (cond-mat.quant-gas)

description: We consider self-localization of a small number of Bose particles immersed in a large homogeneous superfluid mixture of fermions in three and one dimensional spaces. Bosons distort the density of surrounding fermions and create a potential well where they can form a bound state analogous to a small polaron state. In the three dimensional volume we observe the self-localization for repulsive interactions between bosons and fermions. In the one dimensional case bosons self-localize as well as for attractive interactions forming, together with a pair of fermions at the bottom of the Fermi sea, a vector soliton. We analyze also thermal effects and show that small non-zero temperature affects the pairing function of the Fermi-subsystem and has little influence on the self-localization phenomena.

Roughness correction to the Casimir force beyond perturbation theory

description: Up to now there has been no reliable method to calculate the Casimir force when surface roughness becomes comparable with the separation between bodies. Statistical analysis of rough Au films demonstrates rare peaks with heights considerably larger than the root-mean-square (rms) roughness. These peaks define the minimal distance between rough surfaces and can be described with extreme value statistics. We show that the contributions of high peaks to the force can be calculated independently of each other while the contribution of normal roughness can be evaluated perturbatively beyond the proximity force approximation. The developed method allows a reliable force estimation for short separations. Our model explains the strong hitherto unexplained deviation from the normal Casimir scaling observed experimentally at short separations.

Homogeneous studies of transiting extrasolar planets. III. Additional planets and stellar models

Year: 2010

subject: FOS: Physical sciences

description: I derive the physical properties of 30 transiting extrasolar planetary systems using a homogeneous analysis of published data. The light curves are modelled with the JKTEBOP code, with attention paid to limb darkening and eccentricity. The light from some systems is contaminated by faint nearby stars, which if ignored will systematically bias the results. I show that this must be accounted for using external measurements of the amount of contaminating light. A contamination of 5% is enough to make the measurement of a planetary radius 2% too low. The physical properties of the 30 transiting systems are obtained by interpolating in stellar model predictions to find the best match to their measured quantities. The error budgets are used to compile a list of systems which would benefit from additional observations. The systematic errors arising from the inclusion of stellar models are assessed by using five different theoretical models. This model dependence sets a lower limit on the accuracy of measurements of the system properties, and at worst is 1% for the stellar mass. The correlations of planetary surface gravity and mass with orbital period have significance levels of only 3.1 sigma and 2.3 sigma. The division of planets into two classes based on Safronov number is increasingly blurred. Most of the objects studied here would benefit from more photometry and/or spectroscopy, as well as a better understanding of low-mass stars.

description: We study segregation phenomena in 57 groups selected from the 2PIGG catalog of galaxy groups. The sample corresponds to those systems located in areas of at least 80% redshift coverage out to 10 times the radius of the groups. The dynamical state of the galaxy systems was determined after studying their velocity distributions. We have used the Anderson-Darling test to distinguish relaxed and non-relaxed systems. This analysis indicates that 84% of groups have galaxy velocities consistent with the normal distribution, while 16% of them have more complex underlying distributions. Properties of the member galaxies are investigated taking into account this classification. Our results indicate that galaxies in Gaussian groups are significantly more evolved than galaxies in non-relaxed systems out to distances of about 4R200, presenting signficantly redder (B-R) color. We also find evidence that galaxies with M_R < -21.5 in Gaussian groups are closer to the condition of energy equipartition.

description: We present the results of an optical spectroscopic study of 12 GALEX-discovered star-forming Lyman alpha emitting galaxies (LAEs) at z ~ 0.3. We measure the emission line fluxes from these galaxies by fitting their observed spectra to stellar population models in order to correct for underlying stellar absorption. We revisit earlier stellar population model fitting results, finding that excluding now-known AGNs lowers the typical stellar population age and stellar mass of this sample to ~ 300 Myr and ~ 4 x 10^9 Msol, respectively. We calculate their dust extinction using the Balmer decrement, and find a typical visual attenuation of Av ~ 0.3 mag, similar to that seen in many high-redshift LAEs. Comparing the ratio of Lyalpha/Halpha and the Lyman alpha equivalent widths to the measured dust extinction, we find that the ISMs in these objects appear to be neither enhancing nor seriously attenuating the Lyman alpha equivalent widths, as would be the case in a quasi-clumpy ISM. Lastly, we perform a detailed analysis of the gas-phase metallicities of these galaxies, and we find that most galaxies in our sample have Z < 0.4 Zsol. We find that at a fixed stellar mass, these low-redshift LAE analogs are offset by ~ 0.6 dex lower in metallicity from the general galaxy population at similar redshifts based on the local mass-metallicity relationship. This implies that galaxies with Lyman alpha in emission may be systematically more metal poor than star-forming galaxies at the same stellar mass and redshift, similar to preliminary results at z ~ 2.

description: Die Universität ist für eine ebenso sinnvolle wie notwendige Demokratieförderung prädestiniert. Diesem Anspruch kann sowohl auf überfachlicher als auch auf fachlicher Ebene entsprochen werden. Im Hinblick auf das Lehramtsstudium im Fach Sport zeigt dieser Beitrag, dass der schulische Sportunterricht als adressiertes berufliches Zielfeld spezifische Anschlussofferten bietet, die sich bildungstheoretisch durch den sogenannten Doppelauftrag einer Erziehung im und durch Sport ergeben – verstanden als Bewegungsbildung und allgemeine Bildung. Vor diesem Hintergrund lassen sich Potenziale einer Förderung habituell-demokratischer Kompetenzen herausarbeiten. Von diesen Potenzialen ausgehend versuchen wir zu ergründen, wie solche Überlegungen zur Demokratieförderung im schulischen Sportunterricht auch im sportwissenschaftlichen Hochschulstudium vermittelt werden können. Im Ergebnis (Perspektive 1) profiliert dies eine demokratiespezifische Kompetenzerwartung, wonach Studierende im Lehramt des Fachs Sport a) theoretische Kenntnisse über die Bedingungen der Möglichkeit eines demokratiefördernden Sportunterrichts verstehen, b) strukturelle Besonderheiten und Limitationen des Settings kennen und c) prinzipielle Lösungen für fachliche Vermittlungsfragen finden können sollten. Es zeigt sich jedoch auch, dass solche Erwartungen zu vage bleiben, wenn nicht auch die Erarbeitungsprozesse und mithin die Hochschullehre selbst in einem demokratiefördernden Milieu stattfinden. Daher wird auch skizziert (Perspektive 2), wie Bildungsgehalte des Sports in der eigenen Erfahrung erschlossen und mit Fragen nach den Zielen, Wegen und der Verantwortbarkeit des schulischen Sportunterrichts verbunden werden können. Schließlich wird dafür plädiert, solche durchaus mäeutischen Wege der Lehre verstärkt zu nutzen.

Design and optimization of a microfluidic system for the production of protein drug loadable and magnetically targetable biodegradable microspheres
Creators: name: Bokharaei, Mehrdad
Publisher: name: University of British Columbia
Year: 2016

description: The overall goal of this dissertation was to develop a microfluidic system for the production of magnetic and non-magnetic drug-loaded polymer microspheres with narrow size distribution. The size of microspheres is a crucial parameter for their application, as the rate of drug release from the microspheres, the rate of microsphere degradation, and the microsphere biodistribution all correlate with particle size and size distribution. Conventional microsphere production methods generally lead to the formation of particles with broad size distribution. In this work, the conventional emulsification-evaporation method for the production of microspheres was miniaturized into microfluidic flow focusing system. Using a self-designed flow focusing chip, quasi-monodisperse poly (lactic acid) microspheres were prepared. The spherical shape and narrow size distribution of the initial polymer-chloroform droplets generated at the orifice were retained throughout their movement in the channels. After complete solvent removal, the droplets turned into quasi-monosized microspheres with a coefficient of variation between 2% and 16%. To better understand the influence of different parameters on droplet generation, the behavior of the disperse phase and the continuous phase were simulated in a 3D computational multiphase droplet generation model. The experimentally determined droplet sizes correlated well with the computational model and never digressed more than 17% from the simulations. The flow focusing system was then also used directly, for the first time, to produce superparamagnetic microspheres containing 15% magnetic nanoparticles. The microspheres’ thermal properties showed their suitability for magnetic hyperthermia of large tumors in cancer therapy. The microfluidic chip was then further altered into a novel device that is able to encapsulate proteins into the polymer microspheres by integrating flow focusing and passive droplet break up systems into one-chip which contained sections of differing surface properties. With this design, bovine serum albumin-loaded microspheres could be prepared with a protein encapsulation efficiency of up to 96%. The work presented in this dissertation is the first to show that a microfluidic system can be used for the continuous production of quasi-monodisperse magnetic microspheres and protein-drug-loaded polymer microspheres. These microspheres will be useful in hyperthermia treatment, diagnostic imaging, and the targeted and controlled delivery of protein based drugs.

description: This paper analyses and explains from the systems point of view, microprocessor based protective relay (MBPR) systems with emphasis on differential equation algorithms. Presently, the application of protective relaying in power systems, using MBPR systems, based on the differential equation algorithm is valued more than the protection relaying based on any other type of algorithm, because of advantages in accuracy and implementation. MBPR differential equation approach can tolerate some errors caused by power system abnormality such as DC offset. This paper shows that the algorithm is a system description based and it is immune from distortions such as DC-offset. Differential equation algorithms implemented in MBPR are widely used in the protection of transmission and distribution lines, transformers, buses, motors, etc. The parameters from the system, utilized in these algorithms, are obtained from the power system current i(t) or voltage v(t), which are abnormal values under fault or distortion situations. So, an error study for the algorithm is considered necessary.

description: We study the distribution P(ω) of the random variable ω= x_1/(x_1 + x_2), where x_1 and x_2 are the wealths of two individuals selected at random from the same tempered Paretian ensemble characterized by the distribution Ψ(x) \sim ϕ(x)/x^{1 + α}, where α> 0 is the Pareto index and $ϕ(x)$ is the cut-off function. We consider two forms of ϕ(x): a bounded function ϕ(x) = 1 for L \leq x \leq H, and zero otherwise, and a smooth exponential function ϕ(x) = \exp(-L/x - x/H). In both cases Ψ(x) has moments of arbitrary order. We show that, for α> 1, P(ω) always has a unimodal form and is peaked at ω= 1/2, so that most probably x_1 \approx x_2. For 0 < α< 1 we observe a more complicated behavior which depends on the value of δ= L/H. In particular, for δ< δ_c - a certain threshold value - P(ω) has a three-modal (for a bounded ϕ(x)) and a bimodal M-shape (for an exponential ϕ(x)) form which signifies that in such ensembles the wealths x_1 and x_2 are disproportionately different.

description: Assume that for some $α<1$ and for all nutural $n$ a set $F_n$ of at most $2^{αn}$ "forbidden" binary strings of length $n$ is fixed. Then there exists an infinite binary sequence $ω$ that does not have (long) forbidden substrings. We prove this combinatorial statement by translating it into a statement about Kolmogorov complexity and compare this proof with a combinatorial one based on Laslo Lovasz local lemma. Then we construct an almost periodic sequence with the same property (thus combines the results of Levin and Muchnik-Semenov-Ushakov). Both the combinatorial proof and Kolmogorov complexity argument can be generalized to the multidimensional case.

description: We report the measurement of the parity violating single spin asymmetries for inclusive high transverse momentum electrons and positrons in polarized $p+p$ collisions at a center of mass energy of $\sqrt{s}=500$ GeV with the PHENIX detector at RHIC. These electrons are attributed to the decay of $W^\pm$ and $Z^0$ bosons, and measured production cross section is consistent with the expectations. The $W$ production is confirmed for the first time in $p+p$ collisions. Its spin asymmetry in the polarized $p+p$ collisions is a important probe for the quark flavor decomposition of the proton spin.

In the brain, androgens are traditionally known for modulation of reproductive behaviors mediated by classical regions rich in ARs. However, there is growing recognition of androgen involvement in higher-order cognitive processes, such as executive functions, which are mediated by non-classical brain regions like the prefrontal cortex (PFC), nucleus accumbens (NAc), and ventral tegmental area (VTA), which are part of the mesocorticolimbic system. In males, executive functions and serum T levels decline with age, but it is unclear how age impacts mesocorticolimbic ARs, and also mesocorticolimbic T levels. In these regions, ARs are present, but often at lower abundances per cell, and are difficult to detect immunochemically. Given the lack of information about mesocorticolimbic ARs and T, and how both may be altered by age, the main goals of this thesis were to: (1) improve immunochemical visualization of ARs, (2) phenotype prefrontal AR-expressing cells, and (3) examine how aging affects levels of ARs and neural T. In brief, we use a male rat model to demonstrate superior detection of ARs through application of tyramide signal amplification (TSA), confirm that prefrontal AR-expressing cells are neuronal and not glial, and show region-dependent reductions in ARs and neural T levels with age. More specifically, we show an age-associated decline in serum T and neural T, but an increase in the ratio of neural T: serum T, suggesting partially compensatory T production may occur in the aging brain. We also show an age-associated decrease in the amount of ARs in the PFC, but not the NAc or VTA. We conclude that the observed declines in T and AR levels may contribute to age-related impairment in executive functions. Furthermore, our results also contribute to improved visualization and examination of mesocorticolimbic ARs, and ultimately, a better understanding of the role they play in cognitive processes.

description: We study the effects of temporal UV-cutoff on the chiral critical surface in hot and dense QCD using a chiral effective model. Recent lattice QCD simulations indicate that the curvature of the critical surface might change toward the direction in which the first order phase transition becomes stronger on increasing the number of lattice sites. To investigate this effect on the critical surface in an effective model approach, we use the Nambu-Jona-Lasinio model with finite Matsubara frequency summation. We find that qualitative feature of the critical surface does not alter appreciably as we decrease the summation number, which is unlike the case what is observed in the recent lattice QCD studies. This may either suggest the dependence of chemical potential on the coupling strength or due to some additional interacting terms such as vector interactions which could play an important role at finite density.

description: The generation of magnetic flux in the solar interior and its transport to the outer solar atmosphere will be in the focus of solar physics research for the next decades. One key-ingredient is the process of magnetic flux emergence into the solar photosphere, and the reorganization to form the magnetic phenomena of active regions like sunspots and pores. On July 4, 2009, we observed a region of emerging magnetic flux, in which a proto-spot without penumbra forms a penumbra within some 4.5 hours. This process is documented by multi-wavelength observations at the German VTT: (a) imaging, (b) data with high resolution and temporal cadence acquired in Fe I 617.3 nm with the 2D imaging spectropolarimter GFPI, and (c) scans with the slit based spectropolarimeter TIP in Fe I 1089.6 nm. MDI contiuum maps and magnetograms are used to follow the formation of the proto-spot, and the subsequent evolution of the entire active region. During the formation of the penumbra, the area and the magnetic flux of the spot increases. The additional magnetic flux is supplied by the adjacent region of emerging magnetic flux: As emerging bipole separate, the poles of the spot polarity migrate towards the spot, and finally merge with it. As more and more flux is accumulated, a penumbra forms. From inversions we infer maps for the magnetic field and the Doppler velocity (being constant along the line-of-sight). We calculate the magnetic flux of the forming spot and of the bipole footpoints that merge with the proto-spot. We witness the onset of the Evershed flow and the associated enhance of the field inclination as individual penumbral filaments form. Prior to the formation of individual penumbral sectors we detect the existence of 'counter' Evershed flows. These in-flows turn into the classical radial Evershed outflows as stable penumbra segments form.

description: Many standard structural quantities, such as order parameters and correlation functions, exist for common condensed matter systems, such as spherical and rod-like particles. However, these structural quantities are often insufficient for characterizing the unique and highly complex structures often encountered in the emerging field of nano and microscale self-assembly, or other disciplines involving complex structures such as computational biology. Computer science algorithms known as "shape matching" methods pose a unique solution to this problem by providing robust metrics for quantifying the similarity between pairs of arbitrarily complex structures. This pairwise matching operation, either implicitly or explicitly, lies at the heart of most standard structural characterization schemes for particle systems. By substituting more robust "shape descriptors" into these schemes we extend their applicability to structures formed from more complex building blocks. Here, we describe several structural characterization schemes and shape descriptors that can be used to obtain various types of structural information about particle systems. We demonstrate the application of shape matching algorithms to a variety of example problems, for topics including local and global structure identification and classification, automated phase diagram mapping, and the construction of spatial and temporal correlation functions. The methods are applicable to a wide range of systems, both simulated and experimental, provided particle positions are known or can be accurately imaged.

description: We characterize the elastic contribution to the surface free energy of a nematic in presence of a sawtooth substrate. Our findings are based on numerical minimization of the Landau-de Gennes model and analytical calculations on the Frank-Oseen theory. The nucleation of disclination lines (characterized by non-half-integer winding numbers) in the wedges and apexes of the substrate induces a leading order proportional to qlnq to the elastic contribution to the surface free energy density, q being the wavenumber associated with the substrate periodicity.

Automated Parking Lot Monitoring System

description: The purpose of this project was to create a proof-of-concept vision based automated parking space monitoring system to monitor the number of empty parking spaces in a defined area. This project was specifically targeted toward parking lot J at the University of Southern Indiana with a desired camera placement on the third floor of the Business and Engineering Center. This lot was selected as it has limited spaces while being the closest lot to several university buildings, resulting in high vehicle and pedestrian traffic during peak times. The original idea to solve this proposed by various faculty was to implement a camera and image processing solution in a thirdfloor window of the USI Business and Engineering building as it would be possible to do so with no added infrastructure. A computer vision model using the opensource program TensorFlow was selected as a solution to this problem due to the relatively low cost and minimal necessary infrastructure for operation. This software was implemented on an NVIDIA Jetson Nano using the SSD Mobilenet detection architecture. A transfer learning approach was used to retrain the SSD Mobilenet detection architecture to tailor it to this application. Custom datasets were generated to improve results. An additional detection model was created to automate parking space location detection. The final design is able to accurately detect vehicles within a designated area. Due to limitations regarding perspective and image processing resolution, the final design cannot be implemented solely through camera placement on the third floor of the Business and Engineering building. A cost analysis determined that the added infrastructure required to implement a multi-camera solution would be similar to the cost of traditional sensor based solutions.

Dusty Explosions from Dusty Progenitors: The Physics of SN2008S and the 2008 NGC300-OT

description: SN2008S and the 2008 NGC300-OT were explosive transients of stars self-obscured by very dense, dusty stellar winds. An explosive transient with an un-observed shock break-out luminosity of order 10^10 Lsun is required to render the transients little obscured and visible in the optical at their peaks. Such a large break-out luminosity then implies that the progenitor stars were cool, red supergiants, most probably ~9 Msun extreme AGB (EAGB) stars. As the shocks generated by the explosions propagate outward through the dense wind, they produce a shock luminosity in soft X-rays that powers the long-lived luminosity of the transients. Unlike typical cases of transients exploding into a surrounding circumstellar medium, the progenitor winds in these systems are optically thick to soft X-rays, easily absorb radio emission and rapidly reform dust destroyed by the peak luminosity of the transients. As a result, X-rays are absorbed by the gas and the energy is ultimately radiated by the reformed dust. Three years post-peak, both systems are still significantly more luminous than their progenitor stars, but they are again fully shrouded by the re-formed dust and only visible in the mid-IR. The high luminosity and heavy obscuration may make it difficult to determine the survival of the progenitor stars for ~10 years. However, our model indicates that SN2008S, but not the NGC300-OT, should now be a detectable X-ray source. SN2008S has a higher estimated shock velocity and a lower density wind, so the X-rays begin to escape at a much earlier phase.
