description: Menopausal women have been choosing natural alternatives over conventional hormone treatments to manage their symptoms, partly due to a reported increase in risk of breast carcinogenesis from hormone therapy that consists of conjugated estrogens and medroxyprogesterone. The popular botanicals-hops, red clover, licorice, and epimedium-are some of the dietary supplements used to alleviate these symptoms, which include hot flashes and night sweats. They contain phytoestrogens-compounds that behave like estrogens-known as flavonoids and isoflavonoids. These activate estrogen receptors (ER) α and β when consumed. ERα activity includes cellular proliferation, while ERβ attenuates this ERα-induced function, thus regulating proliferation. ERβ is also suggested to have a chemoprotective role in vivo. We hypothesized that botanicals containing ERβ-preferential (iso)flavonoids may be able to provide ERβ-related protective benefits by counterbalancing ERα proliferation. In this study, the initial aims included optimizing estrogenic screening assays to identify ERβ-preferential (iso)flavonoids present in select botanicals. Using bioassay-guided fractionation, 8-prenylapigenin (8-PA) was isolated from the tested licorice extract and identified as a potent ERβ-preferential agonist with nanomolar EC50 values. Secondly, a structure activity relationship (SAR) study was conducted to identify (iso)flavonoid structures that favor ERβ-preferential activity. Notable (iso)flavonoids analyzed included 8-prenylnaringenin, 8-prenylapigenin, apigenin, naringenin, genistein, 8-prenylgenistein. Results showed that prenylation on the 8-position of the A-ring of flavonoids increased overall estrogenic activity, and when combined with C2-C3 unsaturation on the C-ring, this resulted in an increase in ERβ potency. In contrast, this same prenylation on isoflavonoids resulted in a decrease in overall estrogenic activity, while the absence of prenylation with C2-C3 unsaturation on the C-ring increased ERβ-preferential potency. Select women’s health botanicals are used for menopausal symptoms, and these induce ERα activity when consumed. However, if they contain ERβ-preferential (iso)flavonoids, these may contribute chemoprotective benefits through ERβ activity that attenuates ERα-induced proliferation, reducing the risk of breast carcinogenesis. These botanicals may offer a beneficial safety profile, while providing potential health benefits.

description: Ambivalence is a prevalent phenomenon in organizations. However, little is known about this phenomenon. The experience of ambivalence is uncomfortable, but it can lead to both good and bad outcomes. The distinguishing factor here is the response. In this dissertation, I present two studies wherein a model of response to ambivalence (RTA) was developed and tested. RTA refers to conscious efforts to reduce the intensity of ambivalence experienced. In study 1, I developed a measurement of distinct RTAs (avoidance, domination, compromise, and holism) based on the framework created by Ashforth et al. (2014). Through five rounds of data collection, I established the RTA scale psychometric properties and convergent and discriminant validity as well as its measurement utility across different frames of reference. In study 2, drawing on the Conservation of Resources (COR) theory (Hobfoll, 1989), I employed a time-lagged design to examine how resources influence people’s choice of RTA strategies and how these responses influence employee change-oriented behaviors. The results of the field study (n=265) revealed that higher availability of resources was positively associated with compromise and holism but negatively associated with avoidance and domination. Furthermore, greater compromise and holism predicted higher change-oriented behaviors. However, avoidance and domination were not associated with lower change-oriented behaviors.

description: After 26 years from the major event of 1990, in early 2016 the puzzling symbiotic binary MWC 560 has gone into a new and even brighter outburst. We present our tight BVRI photometric monitoring of MWC 560 (451 independent runs distributed over 357 different nights), covering the 2005-2016 interval, and the current outburst in particoular. A stricking feature of the 2016 outburst has been the suppression of the short term chaotic variability during the rise toward maximum brightness, and its dominance afterward with an amplitude in excess of 0.5 mag. Similar to the 1990 event when the object remained around maximum brightness for ~6 months, at the time Solar conjunction prevented further observations of the current outburst, MWC 560 was still around maximum, three months past reaching it. We place our observations into a long term contex by combining with literature data to provide a complete 1928-2016 lightcurve. Some strong periodicities are found to modulate the optical photometry of MWC 560. A period of 1860 days regulate the occourence of bright phases at BVR bands (with exactly 5.0 cycles separating the 1990 and 2016 outbursts), while the peak brightness attained during bright phases seems to vary with a ~9570 days cycle. A clean 331 day periodicity modulate the I-band lightcurve, where the emission from the M giant dominates, with a lightcurve strongly reminiscent of an ellipsoidal distortion plus irradiation from the hot companion. Pros and cons of 1860 and 331 days as the system orbital period are reviewed, waiting for a spectroscopic radial velocity orbit of the M giant to settle the question (provided the orbit is not oriented face-on).

Pervious Concrete Accessible Pathways: Usability for Individuals with Disabilities

Subjects: Uncategorized

description: The Americans with Disabilities Act Accessibility Guidelines describe accessible routes as needing to be firm, stable, and slip-resistant. No mention is made of route smoothness. While the U.S. Access Board provides recommendations regarding coefficient of friction values for horizontal surfaces and ramps, it notes that research is needed regarding both slip-resistance and smoothness before any requirements can be considered. The slip-resistance and smoothness characteristics were studied for a material increasingly used for accessible routes, pervious concrete. A total of 9 pervious concrete pathways in the community were included in the study, along with 3 pathways constructed of standard concrete. Coefficient of friction values were measured using the Brungraber Mark IV device. Pathway roughness was measured with a rolling profilometer, the SurPRO 4000, used by many concrete industry and roadway inspection professionals. Data was taken to determine the pathway International Roughness Index, and the recently-developed Wheelchair Pathway Roughness Index. Additionally, a lightweight manual wheelchair, typical for an active wheelchair user, was instrumented with accelerometers to measure the whole-body vibration (WBV) experienced by a simulated wheelchair user. Data was taken at two velocities, 0.75 m/s and 1.00 m/s, over a 30m pathway. Coefficient of friction values were found to be in compliance with ADAAG recommendations, except in one location where sealant had been recently applied. Pathway roughness values were similar to roadways considered in good condition. Pervious concrete roughness values were both above and below the values of the control pathways. WBV levels indicated that travel on pervious concrete pathways is safe for wheelchair users when using the ISO 2631 to determine vibration health hazards, especially when research regarding actual daily wheelchair travel in the community is taken into account.

No excess above the Standard Model background expectation is observed in the various signal regions and 95% confidence level upper limits on the visible cross section for new phenomena are set. The results of the analysis are interpreted in several SUSY scenarios, significantly extending previous limits obtained in the same final states. In the framework of minimal gauge-mediated SUSY breaking models, values of the SUSY breaking scale Lambda below 63 TeV are excluded, independently of tan(beta). Exclusion limits are also derived for an mSUGRA/CMSSM model, in both the R-parity-conserving and R-parity-violating case. A further interpretation is presented in a framework of natural gauge mediation, in which the gluino is assumed to be the only light coloured sparticle and gluino masses below 1090 GeV are excluded.

description: We present a quintuple star system that contains two eclipsing binaries. The unusual architecture includes two stellar images separated by 11" on the sky: EPIC 212651213 and EPIC 212651234. The more easterly image (212651213) actually hosts both eclipsing binaries which are resolved within that image at 0.09", while the westerly image (212651234) appears to be single in adaptive optics (AO), speckle imaging, and radial velocity (RV) studies. The 'A' binary is circular with a 5.1-day period, while the 'B' binary is eccentric with a 13.1-day period. The gamma velocities of the A and B binaries are different by ~10 km/s. That, coupled with their resolved projected separation of 0.09", indicates that the orbital period and separation of the 'C' binary (consisting of A orbiting B) are ~65 years and ~25 AU, respectively, under the simplifying assumption of a circular orbit. Motion within the C orbit should be discernible via future RV, AO, and speckle imaging studies within a couple of years. The C system (i.e., 212651213) has a radial velocity and proper motion that differ from that of 212651234 by only ~1.4 km/s and ~3 mas/yr. This set of similar space velocities in 3 dimensions strongly implies that these two objects are also physically bound, making this at least a quintuple star system.

description: Women with HIV are vulnerable to cognitive dysfunction compared to male counterparts. Genetic factors have not been widely examined as a contributor to cognitive dysfunction in HIV+ women. The goal of this study was to examine cognitive function in relation to Apolipoprotein E (APOE) genotype in HIV+ and HIV- women. A total of 714 women from the Women’s Interagency HIV Study (WIHS) (68.9% HIV+, 32.9% ε4+) had both longitudinal cognitive data over three visits and APOE genotyping available for analysis. We found there was no main effect of APOE genotype on any cognitive domain. We found a significant interactive effect of HIV, APOE and time on global cognition, driven by small negative effects of the APOE ε4 allele in the HIV- control group. Finally, we found that in HIV+ women, there was a significant interactive effect between APOE and age on executive functioning, global cognition, motor skills, and processing speed, such that older HIV+ ε4+ women performed worse than older HIV+ ε4- women. In contrast, there was no main effect of APOE ε4 carrier status on any cognitive domain in younger HIV+ women or either age group of HIV- controls. Overall, the current findings suggest that APOE genotype may be an age-related risk factor for cognitive dysfunction in HIV+ women.

description: Because global topological properties are robust against local perturbations, understanding and manipulating the topological properties of physical systems is essential in advancing quantum science and technology. For quantum computation, topologically protected qubit operations can increase computational robustness, and for metrology the quantized Hall effect directly defines the von Klitzing constant. Fundamentally, topological order is generated by singularities called topological defects in extended spaces, and is quantified in terms of Chern numbers, each of which measures different sorts of fields traversing surfaces enclosing these topological singularities. Here, inspired by high energy theories, we describe our synthesis and characterization of a singularity present in non-Abelian gauge theories - a Yang monopole - using atomic Bose-Einstein condensates in a five-dimensional space, and quantify the monopole in terms of Chern numbers measured on enclosing manifolds. While the well-known 1st Chern number vanished, the 2nd Chern number, measured for the first time in any physical settings, did not. By displacing the manifold, we then observed a phase transition from "topological" to "trivial" as the monopole left the manifold.

Asynchronous Delegation and Applications

description: Parallel programs commonly synchronize shared memory accesses through implementation of mutual exclusion locks. This approach, where multiple OS threads access the same data structure, suffers from poor performance when data structures are contended and makes little use of a processor’s on-core cache. Delegation, as presented by Roghanchi, et. al. in Gepard, is a scheme where a server thread is given exclusive control of a data structure and operations are requested by client threads via message passing. Delegation has been shown to increase throughput in highly parallel systems over coarse grained locks, however the approach suffers from the latency required to pass messages between threads. Gepard masks this latency by introducing concurrency in message passing through the use of lightweight user space threads called fibers. However, Gepard is unable to achieve enough concurrency to increase system throughput over fine grained locking approaches when variables are uncontended. We present asynchronous designs for dedicated and flat delegation. The asynchronous API enables greater message passing concurrency and reduced memory footprint than that of Gepard. The impact is an over 30% increase in total system throughput, on our benchmark, than that of locking approaches when delegated data structures are resident in a delegation server’s on-core cache. We provide rationale for our design decisions and examine the performance of these designs on a fetch and add type microbenchmark.

We Really Do Live Here: Strategies for Rural Queer and Trans* Women

description: My dissertation draws on in-depth interviews (n=33) to explore the experiences of queer and trans* women in rural spaces. Using literatures from urban and rural sociology, geography, gender, sexualities, and queer studies, I argue that rural spaces, while often considered unwelcoming and closed minded, can also be conducive to queer and trans* lives. I specifically focus on the strategies that queer and trans* women use to negotiate the places where they live and the associated challenges. This project not only advances scholarship on rural queer and trans* lives, but also furthers understandings of queer and trans* sexualities and desire, which have been only minimally considered previously. In Chapter 2, I bring together literatures from urban and rural sociology, geography, gender, sexualities, and queer studies to show that there is a significant gap in the overall literatures on rural spaces, often referred to as the urban/rural divide. Chapter 3 considers the methodology of the project. Chapter 4 focuses on the overall strategies that queer and trans* women use in their everyday lives and interactions. The analysis, based on the ways that those who I interviewed discuss their everyday lives and interactions with individuals, groups, and institutions, shows how queer and trans* women use a range of strategies, depending on where they’re at as well as the situations and processes which they’re attempting to navigate. Chapter 5 builds on the previous chapter by specifically considering the topics of community and belonging and the strategies that these women use to not only negotiate these topics but also to work within the various social processes and circumstances related to economics, employment, safety, and discrimination that they face in their everyday lives. Chapter 6 focuses on the relationships that queer and trans* women have in rural spaces. Continuing with the theme of strategies, I focus specifically on interpersonal and romantic relationships. In my conclusion, I consider implications of my work and the need for future research on queer and trans* families and racial and ethnic minorities in rural spaces.

description: High oxidation potential indicates anodes have high oxidation power and high current efficiency for organics oxidation. In this paper, we prepared Ti/Cu-SnO2 anodes using spray pyrolysis method. The Ti/Cu-SnO2 anodes have an ultra-high oxidation potential of about 2.7 V vs NHE, suitable for use in wastewater treatment. The Ti/Cu-SnO2 anodes exhibit the preferred orientation along (110) plane at high Cu doped concentration. First-principles calculations suggest that work function of Cu-SnO2 increases with the Cu doping concentration. It is obtained that the preferred (110) plane and the high work function are responsible for the enhanced oxidation potential of Ti/Cu-SnO2 anodes.

description: Albeit difficult to access experimentally, the density of states (DOS) is a key parameter in solid state systems which governs several important phenomena including transport, magnetism, thermal, and thermoelectric properties. We study DOS in an ensemble of potassium intercalated single-wall carbon nanotubes (SWCNT) and show using electron spin resonance spectroscopy that a sizeable number of electron states are present, which gives rise to a Fermi-liquid behavior in this material. A comparison between theoretical and the experimental DOS indicates that it does not display significant correlation effects, even though the pristine nanotube material shows a Luttinger-liquid behavior. We argue that the carbon nanotube ensemble essentially maps out the whole Brillouin zone of graphene thus it acts as a model system of biased graphene.

description: The computation of perturbative corrections to processes involving heavy quarks is crucial for the precision program of the LHC and future colliders. In this article, we describe a powerful approach to calculate higher-orders in QCD skipping the traditional subtraction method. Our proposal is based on the loop-tree duality (LTD) theorem, which allows to rewrite virtual contributions in terms of integrals over the real emission phase-space. Then, we proceed to combine both real and virtual contributions at the integrand level, obtaining regular expressions that can be numerically integrated in four space-time dimensions. In this way, we avoid dealing with complicated massive Feynman integrals and introducing infrared counter-terms. Some reference examples are explained, in order to exhibit the potential of our method.

description: The wide variation in upper limb motor impairments among stroke survivors presents a significant challenge to therapy. One approach is to customize treatment based on each individual’s particular movement capabilities. Past work in our lab successfully allowed patients to move any way they wanted, freely exploring while being facilitated by robot-applied forces that amplify their movement velocities. This thesis builds upon this framework by introducing a statistical approach, distribution analysis, for characterizing each patient’s patterns of movement during a special paradigm, free exploration, such that forces can be applied in a customized manner. Distribution analysis first builds a model of each individual’s unique motor deficits, which then informs the design of training forces that push each patient’s hand away from their typical movement velocities (i.e. higher probability bins) and towards their less visited velocity deficits (i.e. lower probability bins). We tracked the recovery of patients across weeks of such training using both clinical assessments and engineering metrics (Chapter II). As the success of any robotic intervention is often determined by whether patients are actively moving their affected limb, we relate their energetic contributions (quantified in terms of mechanical work) during training to their recovery outcomes and combine advanced multiple regression techniques to identify the most important biomechanical components of work (Chapter III). Lastly, we apply distribution analysis across a wider domain of variables (endpoint and joint kinematics, kinetics) and relate them to clinical measures, use them to classify stroke survivors and healthy individuals and describe the individual differences between stroke and healthy (Chapter IV). These findings represent a powerful set of new statistical modeling approaches for stroke therapy.

description: We present fully local versions of the minimally non-local nucleon-nucleon potentials constructed in a previous paper [M.\ Piarulli {\it et al.}, Phys.\ Rev.\ C {\bf 91}, 024003 (2015)], and use them in hypersperical-harmonics and quantum Monte Carlo calculations of ground and excited states of $^3$H, $^3$He, $^4$He, $^6$He, and $^6$Li nuclei. The long-range part of these local potentials includes one- and two-pion exchange contributions without and with $Δ$-isobars in the intermediate states up to order $Q^3$ ($Q$ denotes generically the low momentum scale) in the chiral expansion, while the short-range part consists of contact interactions up to order $Q^4$. The low-energy constants multiplying these contact interactions are fitted to the 2013 Granada database in two different ranges of laboratory energies, either 0--125 MeV or 0--200 MeV, and to the deuteron binding energy and $nn$ singlet scattering length. Fits to these data are performed for three models characterized by long- and short-range cutoffs, $R_{\rm L}$ and $R_{\rm S}$ respectively, ranging from $(R_{\rm L},R_{\rm S})=(1.2,0.8)$ fm down to $(0.8,0.6)$ fm. The long-range (short-range) cutoff regularizes the one- and two-pion exchange (contact) part of the potential.

Experimental and Theoretical Investigation of Heat and Mass Transfer Processes in Porous Media

Publisher: name: University of Illinois at Chicago
Year: 2019
Subjects: Uncategorized

description: The present work aims at the further understanding of peculiarities of heat and mass transfer in porous media by the experimental and theoretical approaches. Chapters 4, 5 and 6 are devoted to the mass transfer processes in non-deformable porous materials. In these three chapters, the adsorption/desorption processes during the diffusion mass transport and the detection methods of the released vapor are studied for such porous materials as sand and clay. Highly sublimating materials, such as camphor and naphthalene, are buried in these porous media and used as a model sublimating vapor source. In relation to the experiments, theoretical/numerical models are also developed in these three chapters. Chapters 7- 10 have the heat transfer process in porous deformable nonwovens in focus, which is relevant for the enhancement of mechanical properties using thermal bonding. Tensile testing and blister testing are applied to measure the mechanical properties and the cohesion energy, respectively, of different thermally-bonded nonwovens. Several models related to the descriptions of nonwoven properties and the industrial calender thermal bonding process are developed. Heat and mass transfer mechanisms in vegetation in forest fire are explored experimentally and theoretically in chapters 11 and 12. Chapter 11 explores volatiles and water vapor ejection from pores during biomass burning in forest fires, and chapter 12 studies the velocity of flame propagation of the canopy fire in a model system. Conclusions are drawn in chapter 13.

description: We review the impact of tetrahedral order on the macroscopic dynamics of bent-core liquid crystals. We discuss tetrahedral order comparing with other types of orientational order, like nematic, polar nematic, polar smectic, and active polar order. In particular, we present hydrodynamic equations for phases, where only tetrahedral order exists or tetrahedral order is combined with nematic order. Among the latter we discriminate between three cases, where the nematic director (a) orients along a 4-fold, or (b) along a 3-fold symmetry axis of the tetrahedral structure. For the optically isotropic T_d phase, which only has tetrahedral order, we focus on the coupling of flow with e.g. temperature gradients and on the specific orientation behavior in external electric fields. For the transition to the nematic phase, electric fields lead to a temperature shift that is linear in the field strength. Electric fields induce nematic order, again linear in the field strength. If strong enough, electric fields can change the tetrahedral structure and symmetry leading to a polar phase. We briefly deal with the T phase that arises when tetrahedral order occurs in a system of chiral molecules. To case (a) belong (i) the non-polar, achiral, optically uniaxial D2d phase with ambidextrous helicity and with orientational frustration in external fields, (ii) the non-polar tetragonal S4 phase, (iii) the non-polar, orthorhombic D2 phase that is structurally chiral featuring ambidextrous chirality, (iv) the polar orthorhombic C2v phase, and (v) the polar monoclinic C2 phase. Case (b) results in a trigonal C3v phase that behaves like a biaxial polar nematic phase. Finally we discuss some experiments that show typical effects related to the existence of tetrahedral order.
Bypassing slip velocity: rotational and translational velocities of autophoretic colloids in terms of surface flux

description: A standard approach to propulsion velocities of autophoretic colloids with thin interaction layers uses a reciprocity relation applied to the slip velocity. But the surface flux (chemical, electrical, thermal, etc.), which is the source of the field driving the slip is often more accessible. We show how, under conditions of low Reynolds number and a field obeying the Laplace equation in the outer region, the slip velocity can be bypassed in velocity calculations. In a sense, the actual slip velocity and a normal field proportional to the flux density are equivalent for this type of calculation. Using known results for surface traction induced by rotating or translating an inert particle in a quiescent fluid, we derive simple and explicit integral formulas for translational and rotational velocities of arbitrary spheroidal and slender-body autophoretic colloids.

description: Purpose: The Core Physical Exam (CPE) has been proposed as a basis for the Core + Cluster curriculum for teaching and assessing physical examination (PE) skills in medical students. This study provides initial validity evidence for a modified, institution-specific CPE as an assessment of PE skills in medical students. Methods. The University of Colorado School of Medicine (UCSOM) CPE was developed as a 25- item version of the published CPE. Validity evidence for the UCSOM CPE was gathered using data from two classes of approximately 180 medical students from to September 2015 to December 2018. Validity evidence specific to content, response process, internal structure, relationship to other variables and consequences was gathered. Results: Content and response process evidence was based on the use of content experts to develop the UCSOM CPE and the extensive rater training in the institution’s clinical performance center. Correlations of performance on the UCSOM CPE to other assessments of the PE were generally low in the range of 0.14 to 0.23, consistent with correlations between stations of objective structured clinical examinations. The 90% pass-fail cut point determined by a modified Angoff approach resulted in a fail rate of 10% to 13% for the UCSOM CPE in first year and 36% to 38% in second year. Clinical skills course directors selected a consensus passfail cut score of 80% as a defensible and practical threshold for the UCSOM CPE in its current educational context for entry into supervised clinical practice in the context of a preceptorship experience. Conclusion: Initial validity evidence supports the use of UCSOM CPE as a useful educational strategy for teaching physical examination and as a formative assessment of PE competence in medical students.

description: Recently the new model for the generation of strong large scale magnetic fields in neutron stars, driven by the parity violating interaction, was proposed. In this model, the magnetic field instability results from the modification of the chiral magnetic effect in presence of the electroweak interaction between ultrarelativistic electrons and nucleons. In the present work we study how a nonzero mass of charged particles, which are degenerate relativistic electrons and nonrelativistic protons, influences the generation of the magnetic field in frames of this approach. For this purpose we calculate the induced electric current of these charged particles, electroweakly interacting with background neutrons and an external magnetic field, exactly accounting for the particle mass. This current is calculated by two methods: using the exact solution of the Dirac equation for a charged particle in external fields and computing the polarization operator of a photon in matter composed of background neutrons. We show that the induced current is vanishing in both approaches leading to the zero contribution of massive particles to the generated magnetic field. We discuss the implication of our results for the problem of the magnetic field generation in compact stars.
