Erectile dysfunction medications : a gateway drug for men
Creators: name: Skeldon, Sean Christopher Toshiaki
Publisher: name: University of British Columbia
Year: 2016

description: Background – Erectile dysfunction (ED) has been described as providing a ‘window of curability’ for men at risk of future cardiovascular disease, however there is little evidence on the relationship between erectile dysfunction and modifiable cardiometabolic risk factors. The primary objectives of this thesis were to: 1) determine whether men with ED have a higher risk of having an undiagnosed cardiometabolic risk factor (hypertension, hypercholesterolemia and diabetes), and 2) determine whether the prescription of a phosphodiesterase type 5 inhibitor (PDE5i) for ED leads to an increase in the diagnosis and treatment of these risk factors. Methods – This thesis comprised of two original studies. The first, a cross-sectional analysis using a nationally representative survey from the United States. The second, a population-based empirical study of changes in drug utilization for cardiometabolic risk factors following PDE5i prescription in British Columbia. An individual-level time series analysis with switching replications was utilized for this analysis. Results – Men with ED were found to have double the odds of having undiagnosed diabetes compared to those without ED. This was most significant among middle-aged men (ages 40-59 years), as the predicted probability of having undiagnosed diabetes increased from 1 in 50 in men without ED to 1 in 10 in men with ED. Among men aged 40 to 59 years old in British Columbia, we found a sudden increase in prescriptions for antihypertensives (28 per 1,000), statins (15 per 1,000), and antidiabetics (18 per 1,000) in the 90 days following a new prescription for a PDE5i. For both hypercholesterolemia and diabetes, relevant screening tests performed in the 30 days following PDE5i prescription were responsible for this change. This increase was followed by a significant declining trend in prescriptions for all three drugs. Conclusions – Men with ED have an increased risk for undiagnosed cardiometabolic risk factors. PDE5is can act as a ‘gateway drug’ for men to be newly treated for these risk factors provided physicians perform the requisite screening investigations. Increased education and awareness of this relationship among both patients and physicians is critical for exploiting the potential for preventing future cardiovascular disease.

description: Metaleptobasisfernandezi Racenis. 1955 Figures 37-40 Material. (6♂, 1♀). 4♂, 1♀, Base Camp 2♂, Siapa 2. Remarks. Metaleptobasis Calvert is a difficult genus, chiefly because the amplitude of intraspe. cific variability of most species is unknown. M. fernandezi was described from a single female (Racenis, 1955). The prothoracic hind lobe of the present female (Fig. 37) corresponds well with the holotype and with the figure given by Geijs. kes (1932, sub manicaria, see Racenis, 1955). The mesothoracic horns are reduced to mere tuber. cles. The thoracic middorsal stripe is slightly broader in the female from Base Camp than in the type. With some doubts I am referring also the sixmales to iernandezi. The male of this species has not so far been described. The present specimens are exceedingly similar to M. mauritia Williamson, but differ from that species (only 1♂ compared: Valencia, Trinidad, 7 Apr 1965, T. W. Donnelly leg.) in the superior anal appendages: In mauritia they are slightly narrower and less sharply angled internally in the apical third; the tip is clearly marked- off from the internal margin, and is reddish (Figs. 41-42). In fernandezi the superior appendages are slightly broader and more angled internally in the apical third; the transition between internal margin and tip is smooth, the tip dark brown (Figs. 38-39). The hind border of the pronotum has a metallic green spot in the middle in male mauritia, which is absent in fernandezi. The mesothoracic horns are similarly shaped in both species (males) (Figs. 40. 43). Female mauritia have a differently shaped prothoracic hind lobe (Fig. 44) and developed mesothoracic horns (Fig. 45). The specimens from Base Camp were collected together with M. brysonima , but the two males from Siapa 2 were taken in a (then) dry hollow in the forest.

description: NGC6611 and its parental cloud, the Eagle Nebula (M16), are well-studied star-forming regions, thanks to their large content of both OB stars and stars with disks and the observed ongoing star formation. We identified 834 disk-bearing stars associated with the cloud, after detecting their excesses in NIR bands from J band to 8.0 micron. In this paper, we study in detail the nature of a subsample of disk-bearing stars that show peculiar characteristics. They appear older than the other members in the V vs. V-I diagram, and/or they have one or more IRAC colors at pure photospheric values, despite showing NIR excesses, when optical and infrared colors are compared. We confirm the membership of these stars to M16 by a spectroscopic analysis. The physical properties of these stars with disks are studied by comparing their spectral energy distributions (SEDs) with the SEDs predicted by models of T-Tauri stars with disks and envelopes. We show that the age of these stars estimated from the V vs. V-I diagram is unreliable since their V-I colors are altered by the light scattered by the disk into the line of sight. Only in a few cases their SEDs are compatible with models with excesses in V band caused by optical veiling. Candidate members with disks and photospheric IRAC colors are selected by the used NIR disk diagnostic, which is sensitive to moderate excesses, such as those produced by disks with low masses. In 1/3 of these cases, scattering of stellar flux by the disks can also be invoked. The photospheric light scattered by the disk grains into the line of sight can affect the derivation of physical parameters of ClassII stars from photometric optical and NIR data. Besides, the disks diagnostic we defined are useful for selecting stars with disks, even those with moderate excesses or whose optical colors are altered by veiling or photospheric scattered light.

A theoretically-explained new-variant of Modified-Newtonian-Dynamics (MOND)

description: It is surprising that we hardly know only 5% of the universe. Rest of the universe is made up of 70% of dark-energy and 25% of dark-matter. Dark-energy is responsible for acceleration of the expanding universe; whereas dark-matter is said to be necessary as extra-mass of bizarre-properties to explain the anomalous rotational-velocity of galaxy. Though the existence of dark-energy has gradually been accepted in scientific community, but the candidates for dark-matter have not been found as yet and are too crazy to be accepted. Thus, it is obvious to look for an alternative theory in place of dark-matter. Israel-scientist M. Milgrom has suggested a 'Modified Newtonian Dynamics (MOND)' which appears to be highly successful for explaining the anomalous rotational-velocity. But unfortunately MOND lacks theoretical support. The MOND, in-fact, is (empirical) modification of Newtonian-Dynamics through modification in the kinematical acceleration term 'a' (which is normally taken as $a=\frac{v^{2}}{r}$) as effective kinematic acceleration $a_{effective} = a μ(\frac{a}{a_{0}})$, wherein the $μ$-function is 1 for usual-values of accelerations but equals to $\frac{a}{a_{0}} (\ll 1)$ if the acceleration 'a' is extremely-low lower than a critical value $a_0 (10^{-10} m/s^{2})$. In the present paper, a novel variant of MOND is proposed with theoretical backing; wherein with the consideration of universe's acceleration $a_{d}$ due to dark-energy, a new type of $μ$-function on theoretical-basis emerges out leading to $a_{effective} = a(1 - K \frac{a_{0}}{a})$. The proposed theoretical-MOND model too is able to fairly explain qualitatively the more-or-less 'flat' velocity-curve of galaxy-rotation, and is also able to predict a dip (minimum) on the curve.

description: C-type lectin-like receptor 2 (CLEC-2) is a platelet-activated receptor expressed on the surface of platelet membranes. Soluble CLEC-2 (sCLEC-2) has been receiving attention as a predictive marker for thrombotic predisposition. The present study examined the relationship between sCLEC-2 level and degree of coagulation disorder in septic patients. Seventy septic patients were divided into the sepsis-induced disseminated intravascular coagulation (DIC) (SID) group (n = 44) and non-SID group (n = 26). The sCLEC-2 levels were compared between the two groups. Because we suspected that the sCLEC-2 level was affected by the platelet count, we calculated the sCLEC-2/platelet count ratio (C2PAC index). We further divided septic patients into four groups using the Japanese Association for Acute Medicine (JAAM) DIC scoring system (DIC scores: 0–1, 2–3, 4–5, and 6–8). The C2PAC index was significantly higher in the SID group (2.6 ± 1.7) compared with the non-SID group (1.2 ± 0.5) (P P

The cost of energy transformation and digestibility of macronutrients in northern fur seals (Callorhinus ursinus)
Creators: name: Diaz Gomez, Mariana
Publisher: name: University of British Columbia
Year: 2016

description: Bioenergetic studies can quantify the conversion of chemical energy contained in food to biologically useful energy to understand how changes in diet quality and quantity affect overall energy budgets and nutritional status. However, chemical energy is intrinsically linked to the macronutrients contained in food (i.e., lipid and protein) in terms of energetic density and digestive efficiency. For northern fur seals (Callorhinus ursinus) it is unknown how efficiently they transform dietary gross energy to net energy. I fed six trained adult female fur seals eight experimental diets composed of four prey species (capelin, walleye pollock, Pacific herring, and Magister squid), alone or combined. I measured the fur seals’ digestive efficiency for energy and macronutrients across diets. I also investigated the effect of dietary intake on digestive efficiency, and tested the hypothesis that mixed-species diets provide a greater nutritional return than equivalent single-species diets. I quantified net energy uptake by measuring excreta energy loss and measuring heat increment of feeding. My results revealed significant differences between digestive parameters across diets. I found that digestible energy (95.9–96.7%) was negatively affected by both ingested mass and dietary crude protein. Furthermore, urinary energy loss (9.3–26.7%) increased significantly with increases in dietary crude protein. I also found that the heat increment of feeding (4.3–12.4%) increased with decreasing dietary lipid content. Overall, net energy gain (57.9–83.0%) was positively correlated with lipid content. I found that macronutrient digestibility differed across diets and that, overall, lipids were more digestible (96.0–98.4%) than crude proteins (95.7–96.7%). Also, dietary protein influenced the ability of fur seals to digest lipids and proteins. Overall, my results demonstrate that low lipid prey not only contain less gross energy, but result in proportionally lower net energy gain following digestion, partly due to decreasing digestibility of lipids in high protein diets. I also found that, counter to predictions, mixed-species diets do not provide fur seals with greater energetic or macronutrient gains than single-species diets. These findings contribute to understanding the nutritional ecology of northern fur seals and the impact that changes in diet can have on the fur seals’ nutritional state.

description: Event-B is a refinement-based formal method that has been shown to be useful in developing concurrent and distributed programs. Large models can be decomposed into sub-models that can be refined semi-independently and executed in parallel. In this paper, we show how to introduce explicit control flow for the concurrent sub-models in the form of event schedules. We explore how schedules can be designed so that their application results in a correctness-preserving refinement step. For practical application, two patterns for schedule introduction are provided, together with their associated proof obligations. We demonstrate our method by applying it on the dining philosophers problem.

description: The strong non-linearity plays a significant role in physics, particularly, in designing novel quantum sources of light and matter as well as in quantum chemistry or quantum biology. In simple systems, the photon-photon interaction can be determined analytically. However, it becomes challenging to obtain it for more compex systems. Therefore, we show here how to measure strong non-linearities via allowing the sample to interact with a weakly pumped quantized leaking optical mode. We found that the detected mean-photon number versus pump-field frequency shows several peaks. Interestingly, the interval between neighbour peaks equals the photon-photon interaction potential. Furthermore, the system exhibits sub-Poissonian photon statistics, entanglement and photon switching with less than one photon. Finally, we connect our study with existing related experiments.

description: Molecular dynamics simulations are used to examine the relationship between water-like anomalies and the liquid-liquid critical point in a family of model fluids with multi-Gaussian, core-softened pair interactions. The core-softened pair interactions have two length scales, such that the longer length scale associated with a shallow, attractive well is kept constant while the shorter length scale associated with the repulsive shoulder is varied from an inflexion point to a minimum of progressively increasing depth. As the shoulder well depth increases, the pressure required to form the high density liquid decreases and the temperature up to which the high-density liquid is stable increases, resulting in the shift of the liquid-liquid critical point to much lower pressures and higher temperatures. The pair correlation entropy is computed to show that the excess entropy anomaly diminishes when the shoulder well depth increases. Excess entropy scaling of diffusivity in this class of fluids is demonstrated, showing that decreasing strength of the excess entropy anomaly with increasing shoulder depth results in the progressive loss of water-like thermodynamic, structural and transport anomalies. Instantaneous normal mode analysis was used to index the overall curvature distribution of the fluid and the fraction of imaginary frequency modes was shown to correlate well with the anomalous behaviour of the diffusivity and the pair correlation entropy. The results suggest in the case of core-softened potentials, in addition to the presence of two length scales, energetic and entropic effects associated with local minima and curvatures of the pair interaction play an important role in determining the presence of water-like anomalies and the liquid-liquid phase transition.

description: We report on evaluation of lattice thermal conductivity of GeTe/Sb$_{2}$Te$_{3}$ superlattice (SL) by using femtosecond coherent phonon spectroscopy at various lattice temperatures. The time-resolved transient reflectivity obtained in amorphous and crystalline GeTe/Sb$_{2}$Te$_{3}$ SL films exhibits the coherent $A_{1}$ optical modes at terahertz (THz) frequencies with picoseconds dephasing time. Based on the Debye theory, we calculate the lattice thermal conductivity, including scattering by grain boundary and point defect, umklapp process, and phonon resonant scattering. The results indicate that the thermal conductivity in amorphous SL is less temperature dependent, being attributed to dominant phonon-defect scattering.

description: Models with warped extra dimensions, and their strongly coupled duals, offer a nice solution to the hierarchy problem and a very appealing realisation of flavour. Compatibility with the very stringent electroweak and flavour tests have made a generic picture emerge, with a composite Higgs, partial compositeness and custodial symmetry as the main ingredients. We review the main features of this picture and discuss how -and when- models with warped extra dimensions could be discovered at the Large Hadron Collider.

A single ultimate instar larva of this sex was also caught at Unturan, but was lost just before emergence of the adult. Therefore, any information about the length of the gonapophyses can not be given. However, the larva was very similar in ove· raIl appearance to male specimens. Adults were not observed.

description: Deep near-infrared images recorded with NICI on Gemini South are used to investigate the evolved stellar content in the outer regions of the south east quadrant of the spiral galaxy M83. A diffuse population of asymptotic giant branch (AGB) stars is detected outside of the previously identified young and intermediate age star clusters in the outer disk. The brightest AGB stars have M_K > -8, and the AGB luminosity function (LF) is well-matched by model LFs that assume ages < 1 Gyr. The specific star formation rate (SFR) during the past few Gyr estimated from AGB star counts is consistent with that computed from mid-infrared observations of star clusters at similar radii, and it is concluded that the disruption timescale for star clusters in the outer disk is << 1 Gyr. The luminosity function and specific frequency of AGB stars varies with radius, in a manner that is indicative of lower luminosity-weighted ages at larger radii. Modest numbers of red supergiants are also found, indicating that there has been star formation during the past 100 Myr, while the ratio of C stars to M giants is consistent with that expected for a solar metallicity system that has experienced a constant SFR for the past few Gyrs.

New design tools and characterization methods to study Polymer Electrolyte Membrane fuel cell degradation
Creators: name: Schwager, Maximilian
Publisher: name: University of British Columbia
Year: 2016

description: An increasing energy demand and the need to reduce greenhouse gas emissions promotes a need for sustainable energy systems. Polymer-electrolyte-membrane fuel cells, comprising a carbon-platinum catalyst layer (CL), have reached (pre-)commercial viability. However, performance, durability, and cost targets are not entirely met yet. In a larger perspective, this thesis aims to contribute to the development of novel catalyst quality monitoring methods, gradual catalyst loading strategies, and the link between water management and catalyst degradation. The objectives of this thesis are to design tools and develop methods of investigation for catalyst degradation, characterize different accelerated stress test (AST) protocols, indicate stressors of the occurring degradation, deconvolute the performance decay, and to analyze the locally occurring degradation. Carbon corrosion and platinum dissolution are the major degradation mechanisms during the operation. Start-up and shut-down (SU/SD) events where air purges through the hydrogen containing anode, accelerates the progression of these mechanisms, and amplified performance decay results. This study develops an ex-situ tool and a method to link the water content within the CL to the degradation behavior. Higher water content may accelerate CL failure. The comparison of different SU/SD ASTs revealed the degradation behavior and the influence of various mitigation strategies to reduce the occurring voltage decay. The application of an external resistance resulting in the consumption of electrons reduces the degradation. If the voltage is suppressed by applying an external load, the degradation in high current densities is marginal. The deconvolution of the voltage decay at high current densities reveals the ratio of carbon to non-carbon related losses. The non-carbon related losses remain dominant throughout the initial stages of the AST; later the carbon corrosion related losses become significant. The novel multi-channel-characterization-system revealed larger losses towards the cell’s exit during SU/SD and platinum dissolution ASTs. Chemical platinum degradation caused by higher water content towards the exit dominates. Longer residence times of oxygen within the anode promote degradation towards the exit. In conclusion, this study developed novel diagnostics, assessed the ratio of performance decay related to its mechanisms, estimated a dominance of the non-carbon related losses throughout the initial phase, while localizing the degradation.

We show that even though they are invariant under undeformed E{7(7)}, all of the candidate counterterms violate the deformed E{7(7)} current conservation. The same conclusion follows from the uniqueness of the Lorentz and SU(8) covariant, E{7(7)} invariant unitarity constraint expressing the 56-dimensional E{7(7)} doublet via 28 independent vectors. Therefore E{7(7)} duality predicts the all-loop UV finiteness of perturbative N=8 supergravity.

description: We present a search for the standard model Higgs boson produced with a Z boson in 4.1 fb^-1 of data collected with the CDF II detector at the Tevatron. In events consistent with the decay of the Higgs boson to a bottom-quark pair and the Z boson to electrons or muons, we set 95% credibility level upper limits on the ZH production cross section times the H -> b bbar branching ratio. Improved analysis methods enhance signal sensitivity by 20% relative to previous searches beyond the gain due to the larger data sample. At a Higgs boson mass of 115 GeV/c^2 we set a limit of 5.9 times the standard model value.

description: In this lecture we discuss the basic ingredients for gauge invariant quantum field theories. We give an introduction to the elements of quantum field theory, to the construction of the basic Lagrangian for a general gauge theory, and proceed with the formulation of QCD and the electroweak Standard Model with electroweak symmetry breaking via the Higgs mechanism. The phenomenology of W and Z bosons is discussed and implications for the Higgs boson are derived from comparison with experimental precision data.

description: Miniaturization of technologies to milli-, micro- and nanoscale offers numerous advantages for diagnostic and therapeutic biomedical applications. In comparison to their macro-scale counterparts, these small-scale systems are more portable, less invasive and less costly. They can facilitate rapid, sensitive and high throughput detection of abnormalities, help track disease progression, reduce sample consumption and improve therapeutic efficacy of drug delivery while decreasing systemic toxicity. Thus, there is clearly a need for creating innovative milli-, micro- and nanoscale tools that can uncover new possibilities in detection and treatment of various types of diseases. The overall objective of this dissertation was to develop novel small-scale technologies that could help enhance diagnostic and/or therapeutic outcomes in patients with cancer, opioid addiction and inflammatory bowel disease. First, we developed an echogenically stable nanodroplet ultrasound contrast agent with potential applications in extravascular molecular imaging of tumors and targeted cancer therapies. Then, we created a polymer blend microsphere system that could be integrated in prescription opioid tablets to develop an abuse-deterrent formulation against smoking. Finally, we designed a release system for localized delivery of aminosalicylates from magnetically actuated millirobots in the colon to improve therapeutic outcomes in patients suffering from inflammatory bowel disease. Overall, the technologies we developed could serve as a basis for designing diagnostic and therapeutic tools that are superior to currently existing platforms.

description: We study the evolutions of the nonmagnetic disorder-induced edge states with the disorder strength in the HgTe/CdTe quantum wells. From the supercell band structures and wave-functions, it is clearly shown that the conducting helical edge states, which are responsible for the reported quantized conductance plateau, appear above a critical disorder strength after a gap-closing phase transition. These edge states are then found to decline with the increase of disorder strength in a stepwise pattern due to the finite-width effect, where the opposite edges couple with each other through the localized states in the bulk. This is in sharp contrast with the localization of the edge states themselves if magnetic disorders are doped which breaks the time-reversal symmetry. The size-independent boundary of the topological phase is obtained by scaling analysis, and an Anderson transition to an Anderson insulator at even stronger disorder is identified, in-between of which, a metallic phase is found to separate the two topologically distinct phases.

description: Neuraeschnaharpya Martin, 1909 Material. 1♂, 3♀, Base Camp. Remarks. On 14 February I observed numerous specimens circling through the clearing of the Base Camp. At later dates the species became rather sporadic. Flight activity begun at about 6 30 h p.m. and the green thoracic stripes of Neuraeschna could then still be made out from some distance. Later, increasing darkness would prevent one from distinguish this genus from simultaneously flying Gynacantha's. During day time I never saw any Neuraeschna in the jungle. This is the first record of the species from Venezuela.

Consistent Asymptotic Expansion of Mott's Solution for Oxide Growth

description: Many relatively thick metal oxide films grow according to what is called the parabolic law L = 2At + . . . . Mott explained this for monovalent carriers by assuming that monovalent ions and electrons are the bulk charge carriers, and that their number fluxes vary as t^{-1/2} at sufficiently long t. In this theory no charge is present in the bulk, and surface charges were not discussed. However, it can be analyzed in terms of a discharging capacitor, with the oxide surfaces as the plates. The theory is inconsistent because the field decreases, corresponding to discharge, but there is no net current to cause discharge. The present work, which also includes non-monovalent carriers, systematically extends the theory and obtains the discharge current. Because the Planck-Nernst equations are nonlinear (although Gauss's Law and the continuity equations are linear) this leads to a systematic order-by-order expansion in powers of t^{-1/2} for the number currents, concentrations, and electric field during oxide growth. At higher order the bulk develops a non-zero charge density, with a corresponding non-uniform net current, and there are corrections to the electric field and the ion currents. The second order correction to ion current implies a logarithmic term in the thickness of the oxide layer: L = (2At)^{1/2} + B ln t + . . . . It would be of interest to verify this result with high-precision measurements.

Neutrino Masses from Loop-induced $d \geq 7$ Operators

Year: 2010
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We propose a new scenario where neutrino masses are generated via operators with the mass dimension higher than five, which are induced at the loop level. The scenario is demonstrated with concrete models where neutrino masses are generated via a one-loop dimension-seven operator which is induced through TeV scale dynamics under the exact $Z_{2}$ symmetry. Tiny neutrino masses are naturally induced from the TeV scale dynamics without introducing any artificial assumption on magnitudes of coupling constants. The combination of one-loop factor $1/(4π)^2$ and the factor of the ratio $(v/Λ)^2$ between the electroweak scale $v$ and new physics scale $Λ$ provides sufficient suppression as compared to the model based on the dimension-five operator induced at the tree level. The reproduction of the data for neutrino masses and mixings are discussed under the constraint from experiments for lepton flavour violation. We also mention phenomenological implications at collider experiments and dark matter candidates.

description: The large N limit of the anomalous dimensions of operators in ${\cal N}=4$ super Yang-Mills theory described by restricted Schur polynomials, are studied. We focus on operators labeled by Young diagrams that have two columns (both long) so that the classical dimension of these operators is O(N). At large N these two column operators mix with each other but are decoupled from operators with $n\ne 2$ columns. The planar approximation does not capture the large N dynamics. For operators built with 2, 3 or 4 impurities the dilatation operator is explicitly evaluated. In all three cases, in a certain limit, the dilatation operator is a lattice version of a second derivative, with the lattice emerging from the Young diagram itself. The one loop dilatation operator is diagonalized numerically. All eigenvalues are an integer multiple of $8g_{YM}^2$ and there are interesting degeneracies in the spectrum. The spectrum we obtain for the one loop anomalous dimension operator is reproduced by a collection of harmonic oscillators. This equivalence to harmonic oscillators generalizes giant graviton results known for the BPS sector and further implies that the Hamiltonian defined by the one loop large $N$ dilatation operator is integrable. This is an example of an integrable dilatation operator, obtained by summing both planar and non-planar diagrams.
