title: Planning for Active Transportation in the Western United States: An Alternative  Future for Cache Valley, Utah
Creators: name: Tomlin, Stephanie A.
Publisher: name: Utah State University
Year: 2018

description: Mobility in the western U.S. is defined primarily by the private automobile. Since the conclusion of WWII, the private automobile has become readily available to the public, and as a result, has heavily influenced the design of our modern cities in the west. In recent years the connections between high motor vehicle use and rising obesity rates, crumbling road infrastructure, and deteriorating air quality have caused city officials to reexamine the transportation systems of the west. One solution advocates, city officials, and planning professionals have begun examining is active transportation (walking, cycling, and public transit). Research suggests that a robust active transportation network not only diversifies mobility options, it also encourages compact urban development, cleaner air, and a move active population.
This thesis developed a methodology for examining and documenting the components of an active transportation network in the western U.S. This was done though a comprehensive literature review to glean important active transportation policies, infrastructure, and best practices. Then, two western U.S. case study cities with relatively high amounts of cycling, walking, and public transit use were selected and analyzed with site visits and planning professional interviews. The data gathered throughout this first phase of the research was then synthesized, and reoccurring themes about cycling, walking and public transit were identified. These themes were labeled as the prerequisites for active transportation in cities of the western U.S. and were documented and prioritized based on their potential impact. The themes were vetted by planning professionals in the two case study cities as well as in Cache Valley to insure accuracy and validity. A final version of the prerequisites was then documented.
The final phase of this research applied the prerequisites to the transportation system in Cache Valley, UT in order to insure the list was valid and reproducible under a variety of conditions. The outcome of this phase was GIS map displaying an alternative future for active transportation in Cache Valley, UT.

description: A generic algorithm is developed to reduce the problem of obtaining linear and nonlinear entanglement witnesses of a given quantum system, to convex optimization problem. This approach is completely general and can be applied for the entanglement detection of any N-partite quantum system. For this purpose, a map from convex space of separable density matrices to a convex region called feasible region is defined, where by using exact convex optimization method, the linear entanglement witnesses can be obtained from polygonal shape feasible regions, while for curved shape feasible regions, envelope of the family of linear entanglement witnesses can be considered as nonlinear entanglement witnesses. This method proposes a new methodological framework within which most of previous EWs can be studied. To conclude and in order to demonstrate the capability of the proposed approach, besides providing some nonlinear witnesses for entanglement detection of density matrices in unextendible product bases, W-states, and GHZ with W-states, some further examples of three qubits systems and their classification and entanglement detection are included. Also it is explained how one can manipulate most of the non-decomposable linear and nonlinear three qubits entanglement witnesses appearing in some of the papers published by us and other authors, by the method proposed in this paper.

description: Achieving strong coupling between light and matter excitations in hybrid systems is a benchmark for the implementation of quantum technologies. We recently proposed [arXiv:2110.02984] that strong single-particle coupling between magnons and light can be realized in a magnetized epsilon-near-zero (ENZ) medium, in which magneto-optical effects are enhanced. Here we present a detailed derivation of the magnon-photon coupling Hamiltonian in dispersive media both for degenerate and non-degenerate optical modes, and show the enhancement of the coupling near the ENZ frequency. Moreover, we show that the coupling of magnons to plane-wave non-degenerate Voigt modes vanishes at specific frequencies due to polarization selection rules tuned by dispersion. Finally, we present specific results using a Lorentz dispersion model. Our results pave the way for the design of dispersive optomagnonic systems, providing a general theoretical framework for describing engineering ENZ-based optomagnonic systems.

title: I. Studies Toward the Synthesis of Echinodithianic Acid and II. The Temperature Dependent NMR Spectrum of Methyl N-Acetylsarcosinate
Creators: name: Love, Alan LeRoy
Publisher: name: Utah State University
Year: 1971

description: Approaches to the preparation of echinodithianic acid (5) from 2, 5-dicarbomethoxy-1, 4-dithiane (1) were not successful, due to the inability to carboxylate or carboalkoxylate 1 at carbons 2 and 5. Studies toward the synthesis of 5 utilizing methyl 2-acetamidoacrylate (8) have been investigated. The electrophilic addition of sulfur dichloride to 8 yielded bis-( 2-acetamido-2-carbo-methoxyvin- 1-yl) sulfide, while the addition of thiocyanogen chloride to 8 produced methyl 2-acetamido-J-thiocyanato-acrylate.
As electrophilic additions of unsymmetrical dipolar reagents to methyl 2-acetamidoacrylate (8) are not reported in the literature, the addition of hydrogen bromide to 8 was studied to determine the orientation effect of the acetamido group.
Methyl 2-acetamido-2-bromopropionate (69) was found to be the kinetically favored adduct, while under equilibrium conditions the Michael addition product, methyl 2-acetamido-3- bromopropionate (68), was favored.
The rates of exchange of the acetyl (a) and the N-methyl (b) protons from the cis to the trans form of methyl N-acetylsarcosinate (72) were measured by a total NMR lineshape method and found to be the same within the limits of the experimental method. Thermodynamic activation parameters are reported,
From these data it was concluded that the exchanges of each of the four types of protons (a, b, c, d) in 72 depend solely on hindered rotation about the amide C-N bond.

description: We introduce a function model for the Teichmüller space of a closed hyperbolic Riemann surface. Then we introduce a new metric by using the maximum norm on the function space on the Teichmüller space. We prove that the identity map from the Teichmüller space equipped with the usual Teichmüller metric to the Teichmüller space equipped with this new metric is uniformly continuous. Furthermore, we also prove that the inverse of the identity, that is, the identity map from the Teichmüller space equipped with this new metric to the Teichmüller space equipped with the usual Teichmüller metric, is continuous. Therefore, the topology induced by the new metric is just the same as the topology induced by the usual Teichmüller metric on the Teichmüller space. We give a remark about the pressure metric and the Weil-Petersson metric.

description: We present here the transformations required to recast the Robertson-Walker metric and Friedmann-Robertson-Walker equations in terms of observer-dependent coordinates for several commonly assumed cosmologies. The overriding motivation is the derivation of explicit expressions for the radius R_h of our cosmic horizon in terms of measurable quantities for each of the cases we consider. We show that the cosmological time dt diverges for any finite interval ds associated with a process at R -> R_h, which therefore represents a physical limit to our observations. This is a key component required for a complete interpretation of the data, particularly as they pertain to the nature of dark energy. With these results, we affirm the conclusion drawn in our earlier work that the identification of dark energy as a cosmological constant does not appear to be consistent with the data.

description: Abstract

Huanglongbing (HLB), also known as citrus greening disease, caused by the bacterium Candidatus Liberibacter spp (CLas) is one of the most devastating diseases affecting citrus plants worldwide. CLas is a well-studied bacterium, but the role of microbiome’s in HLB development and progression remains unexplored in Pakistani citrus orchards. This study aimed to investigate and profile the microbiomes associated with HLB escape in Pakistani citrus rhizosphere. Ten different bacterial strains were isolated from HLB free rhizosphere by biochemical screening. Bacterial isolates belonged to the class of Firmicutes and Proteobacteria (gamma Proteobacteria) including Pseudomonas, Enterobacter, Proteus, Citrobacter and Serratia. Analysis of the bacterial diversity abundance revealed that Pseudomonas (82%), Bacillus (75%) and Serratia (69%) were the most abundant bacteria in citrus rhizosphere. The isolated strains were studied for plant growth promoting activities including indole acetic acid (IAA) production, sidophore production, and phosphate solubilization. On the basis of these PGP activities the isolated strains showed positive results highest activities were shown by Bacillus safensis, Bacillus subtilis Pseudomonas putida, Serratia plymutica. Our findings reveal that all these PGPR bacteria are beneficial help to reduce the population of viable Ca. L. asiaticus in HLB diseased tree if used as a biofertilizer. This research work provides a foundation for understanding the interaction between the PGPR and Huanglongbing (HLB) in citrus in Pakistan, paving the way for novel disease management strategies and also improving citrus production in the region.

description: We construct a kind of thermal potential and then put the black hole thermodynamic system in it. In this regard, some thermodynamic properties of the black hole are related to the geometric characteristics of the thermal potential. Driven by the intrinsic thermodynamic fluctuations, the behavior of the black hole in the thermal potential is stochastic. With the help of solving the Fokker-Planck equation analytically, we obtain the discrete energy spectrum of Schwarzschild and Banados-Teitelboim-Zanelli (BTZ) black holes in the thermal potential. For Schwarzschild black hole, the energy spectrum is proportional to the temperature of the ensemble, which is an external parameter, and the ground state is non-zero. For BTZ black hole, the energy spectrum only depends on the AdS radius, which is the intrinsic parameter. Moreover, the ground state of BTZ black hole in thermal potential is zero. This also reflects the difference between three-dimensional gravity and four-dimensional gravity.

Year: 2009
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: The Canada-France-Hawaii Telescope Legacy Survey, specifically the Very Wide segment of data, is used to search for possible main-belt comets. In the first data set, 952 separate objects with asteroidal orbits within the main-belt are examined using a three-level technique. First, the full-width-half-maximum of each object is compared to stars of similar magnitude, to look for evidence of a coma. Second, the brightness profiles of each object are compared with three stars of the same magnitude, which are nearby on the image to ensure any extended profile is not due to imaging variations. Finally, the star profiles are subtracted from the asteroid profile and the residuals are compared with the background using an unpaired T-test. No objects in this survey show evidence of cometary activity. The second survey includes 11438 objects in the main-belt, which are examined visually. One object, an unknown comet, is found to show cometary activity. Its motion is consistent with being a main-belt asteroid, but the observed arc is too short for a definitive orbit calculation. No other body in this survey shows evidence of cometary activity. Upper limits of the number of weakly and strongly active main-belt comets are derived to be 630+/-77 and 87+/-28, respectively. These limits are consistent with those expected from asteroid collisions. In addition, data extracted from the Canada-France-Hawaii Telescope image archive of main-belt comet 176P/LINEAR is presented.

title: The Reaction of Dimethyl-and Di-n-butylcopper Lithium with 3-Bromo-2-(2-phenylacetamido) acrylic Acid
Creators: name: Richards, Kim David
Publisher: name: Utah State University
Year: 1975

description: The reaction of dimethylcopper lithium and di-n-butylcopper lithium with 3-bromo-2-(2-phenylacetamido) acrylic acid, mp 174 - 175°, produced as major products 3-methyl-2-(2-phenylacetamido) acrylic acid and 3-n-butyl-2-(2-phenylacetamido) acrylic acid, respectively. The dimethylcopper lithium reaction was stereospecific for the E geometrical isomer, mp 198 - 199°, and produced 3-methyl-2-(2-phenylacetamido) acrylic acid and 2-(2-phenylacetamido) acrylic acid in a 3:1 molar ratio, respectively. The di-n-butylcopper lithium reaction produced as the main products 3-n-butyl-2-(2-phenylacetamido) acrylic acid and 2-(2- phenylacetamido) acrylic acid in a 7:1 molar ratio, respectively, with the 3-n-butylacrylic acid comprising 83% of the product. The reaction produced the E isomer, mp 205 - 206°, and the Z isomer, mp 164 - 165°, in the approximate ratio of 2:1, respectively. The configuration of the products of both reactions was determined by the comparison of the nuclear magnetic resonance spectra with spectra of model compounds of known configuration.
Nuclear magnetic resonance evidence relating to the stereochemistry of 3-bromo-2-(2-phenylacetamido) acrylic acid based on the single isomers of this acid and the corresponding methyl ester reported in the literature was inconclusive. In order that a comparison of the properties of both isomers could be made, an attempt was made to prepare the uncommon isomer of methyl 3-bromo-2-(2-phenylacetamido) acrylate from (a) the common isomer by hydrobromination-dehydrobromination with triethylamine and (b) from methyl 2-(2-phenylacetamido) acrylate by bromination-dehydrobromination with triethylamine. Both attempts were unsuccessful.

description: Abstract

Estrogen is known to increase nitric oxide and endothelial function, decrease endothelin 1 levels and improve lipid profiles. Estrogen suppression by DMPA use may alter endothelial function and other biomarkers of vascular health. This study used a cross sectional study design. Samples were selected using purposive sampling technique. Samples were subjects who met the exclusion and inclusion criteria. There are a total of 88 samples divided into 2 groups; DMPA acceptor group and control group. The collected data will be analysed Univariate and Bivariate. Univariate data analysis aims to describe the dermographic data of respondents by showing the characteristics of the research subjects. Bivariate data analysis is carried out to see the relationship between the dependent variable and the independent variable using the Independent T' Test statistical test if the data is normally distributed, but if the data is not normally distributed then the Mann-Whitney Test is used. The results of this study indicate that in the Body Mass Index (BMI) category, the mean BMI in the DMPA acceptor group is 25 ± 3.60 kg/m2 or Obesity I, while in the control group the mean BMI is 23.25 ± 3.5 kg/m2 or overweight. The mean systolic blood pressure in the DMPA acceptor group was 110 ± 15 mmHg and the mean diastolic blood pressure was 73 ± 9.2, while in the control group the mean systolic blood pressure was 110 ± 9.8 mmHg and the mean diastolic blood pressure was 73 ± 7.4 mmHg. The menstrual cycle category in the DMPA acceptor group found 32 subjects or 72.7% complained of never menstruating during the use of DMPA, while in the control group found 44 subjects or 100% regular menstrual cycles. Kolmogorov-Smirnov normality test of endothelin-1 levels in the DMPA acceptor group and the control group obtained a p value <0.05, namely 0.02 and 0.01 respectively, so it is stated if the data is not normally distributed. From the statistical test using the Mann-Whitney test, the value of p=0.214 was obtained. Because the value of p>α (α=0.05), so it can be concluded if there is no significant difference between plasma endothelin-1 levels in the DMPA acceptor group and the control group. There is an effect of Depot Medroxyprogesterone contraceptive use on increasing Body Mass Index (BMI) and effects on the menstrual cycle, namely amenorrhea, spotting / spotting and irregular / irregular menstruation. There is no significant effect of using Depot Medroxyprogesterone acetate on Endothelin 1 levels.
Effects of three radiosensitizing drugs on radiation-induced DNA damage in hypoxic mammalian cells

Year: 2010

description: The modification of DNA damage by 3 radiosensitizing drugs, present during γ-irradiation of hypoxic Chinese hamster cells, was investigated. The method of alkaline sucrose gradients (ASG's) was used to determine the size distribution of DNA molecules. Both metronidazole and Ro-07-0582 were found to cause large increases in the yield of DNA single strand breaks (SSB's); triacetoneamine-N-oxyl (TAN) was found to have only a small effect on SSB production. A pulse label and chase procedure was used to examine post-irradiation DNA synthesis. TAN present during irradiation under hypoxia was found to cause interruptions in subsequent DNA synthesis. Metronidazole and Ro-07-0582 had no effect on post-irradiation DNA synthesis. In addition, the effects of pre- and post-irradiation exposure to TAN were investigated, since these treatments have shown increased cell killing in survival studies (Agnew and Skarsgard, 1972). TAN pre- and post-treatments were found to have no significant effect on subsequent DNA synthesis.
title: Photochemical Energy Storage (Photosensitized Isomerization of Norbornadiene to Quadricyclane by Copper(I) Complexes)
Creators: name: Fife, Dennis J.
Publisher: name: Utah State University
Year: 1983

description: This research has focused on the sensitized photoisomerization step of a solar energy storage system based on the interconversion of norbornadiene (NBD) and quadricyclane (Q). Sensitizers studied in the photoisomerization were arylphosphine complexes of copper(I) halides [(Ph_3P)_3CuX, (MePh_ 2P)_3CuX, (DIPHOS)CuCl; X = Cl, Br, I and DIPHOS = Ph_ 2P(CH_2)_2PPh_2]. The lowest electronic excited state of the complexes can be an effective triplet energy sensitizer as evidenced by a maximum quantum yield of 1.0 with (HePh_2P)_3CuX. The sensitization mechanism of the L_3CuX complexes is proposed as a bimolecular energy transfer process in which energy transfer takes place through the metal centered orbitals. The efficiency of the (MePh_ 2P)_3CuX sensitizers is unprecedented by other reported inorganic or organic sensitizers; however, ligand dissociation of the complexes in dilute solutions detracts from their otherwise attractive features. The free ligands undergo rapid photodecomposition and are extremely poor sensitizers of the NBD/Q system. The ligand dissociation of the L_mCu_nCl_n (L = Ph_3P, MePh_2P; m:n = 3:1, 2:1, 4:2, 3:2, 2:2) complexes was modeled by use of vapor pressure osmometry and UV absorption. The equilibria and equilibrium constants of dissociation were determined for benzene solutions at 37 °c. The stability of the L_mCu_nCl_n complexes (Ph_3P a_pi transition. Coordination to copper() halides brings about an enhancement of the l -> a_pi transition of the ligand. The term o,d ->a_pi is used to describe the lowest electronic transition of the complexes indicating that both the o bond of the phosphorus lone electron pair to the metal and the d-d orbital bonding of the metal to the phosphorus are involved in an electron excitation from the phosphorus to an antibonding phenyl-pi-system (a_pi ). The photophysical properties of Zn(II), Cu(I), and Ni(O) complexes of MePh_2P are shown to follow the concept of a o,d -> a_pi electronic transition.

description: Abstract

Background: The development of globalization is currently progressing, especially in the field of clinical welfare in providing health services, in this case the quality of patient-centered health services due to the increasing demands of the community for health services that are getting stronger and supported by advances in technology, knowledge and access to information. To improve good health services and to increase patient satisfaction, hospitals need to apply one of the health service concepts, namely the application of patient centered care or also known as PCC. Objective: This study aims to analyze the effect of the application of patient centered care on the satisfaction of inpatients at Lamaddukkelleng Hospital. Methods: The research method used is a quantitative approach with a Cross-Sectional study design and data collection using a questionnaire. The sample in this study was 100 patients using purposive sampling method. Results: Univariate analysis obtained the results of the application of PCC in the good category 66% and the less category 34%, while the results of patient satisfaction were obtained in the satisfied category 41% and unsatisfied 59%. The results of the bivariate test show that there is an effect of the application of patient centered care based on the dimension of respect for patient-centered values, preferences and needs with a p-value = 0.031 <0.05, there is no effect of the application of patient centered care based on the dimensions of coordination and integration with a p-value = 0.699> 0.05, there is no effect of the application of patient centered care based on the dimensions of information, communication, and education with a p-value = 0.985> 0.05, there is no effect of patient centered care based on the dimension of physical comfort with a p-value = 0.150> 0.05, there is no effect of patient centered care based on the dimensions of emotional support and reduction of fear and anxiety with a p-value = 0.065 > 0.05, there is no effect of patient centered care based on the dimensions of family and friend involvement with a p-value = 0.955> 0.5, there is no effect of patient centered care based on the dimensions of transition and continuity of care with a p-value = 0.615> 0.05, there is an effect of patient centered care based on the dimensions of access to care with a p-value = 0.01 <0.05. The results of the multivariate test in this study are the dimensions that have the most influence on patient satisfaction are the dimensions of access to care that have the highest exp(B) value on inpatient satisfaction, namely 4.979. Conclusion: Patient centered care implementation has been running well but does not affect patient satisfaction at Lamaddukkelleng Hospital.
X-Ray Evidence Against the Hypothesis that the Hyper-Luminous z=6.3 Quasar J0100+2802 is Lensed

description: The $z=6.327$ quasar SDSS J010013.02+280225.8 (hereafter J0100+2802) is believed to be powered by a black hole more massive than $10^{10}\ {\rm M}_\odot$, making it the most massive black hole known in the first billion years of the Universe. However, recent high-resolution ALMA imaging shows four structures at the location of this quasar, potentially implying that it is lensed with a magnification of $μ\sim450$ and thus its black hole is significantly less massive. Furthermore, for the underlying distribution of magnifications of $z\gtrsim6$ quasars to produce such an extreme value, theoretical models predict that a larger number of quasars in this epoch should be lensed, implying further overestimates of early black hole masses. To provide an independent constraint on the possibility that J0100+2802 is lensed, we re-analyzed archival XMM-Newton observations of the quasar and compared the expected ratios of X-ray luminosity to rest-frame UV and IR luminosities. For both cases, J0100+2802's X-ray flux is consistent with the no-lensing scenario; while this could be explained by J0100+2802 being X-ray faint, we find it does not have the X-ray or optical spectral features expected for an X-ray faint quasar. Finally, we compare the overall distribution of X-ray fluxes for known, typical $z\gtrsim6$ quasars. We find a $3σ$ tension between the observed and predicted X-ray-to-UV flux ratios when adopting the magnification probability distribution required to produce a $μ=450$ quasar.

In this work we use recent cosmic-ray observations from the AMS-02, CALET and DAMPE collaborations to study the averaged properties of the local Milky Way pulsar population. We perform simulations of the local Milky Way pulsar population, for interstellar medium assumptions in agreement with a range of cosmic-ray nuclei measurements. Each such simulation contains $\sim 10^{4}$ pulsars of unique age, location, initial spin-down power and cosmic-ray electron/positron spectra. We produce more than $7\times 10^{3}$ such Milky Way pulsar simulations. We account for and study i) the pulsars' birth rates and the stochastic nature of their birth, ii) their initial spin-down power distribution, iii) their time evolution in terms of their braking index and characteristic spin-down timescale, iv) the fraction of spin-down power going to cosmic-ray electrons and positrons and v) their propagation through the interstellar medium and the Heliosphere. We find that pulsars of ages $\sim 10^{5}-10^{7}$ yr, have a braking index that on average has to be 3 or larger. Given that electromagnetic spectrum observations of young pulsars find braking indices lower than 3, our work provides strong hints that pulsars' braking index increases on average as they age, allowing them to retain some of their rotational energy. Moreover, we find that pulsars have relatively uniform properties as sources of cosmic-ray electrons and positrons in terms of the spectra they produce and likely release O($10\%$) of their rotational energy to cosmic-rays in the ISM. Finally, we find at $\simeq$12 GeV positrons a spectral feature that suggests a new subpopulation of positron sources contributing at these energies.

description: Abstract

To screen out the potential cultivars through various parameters for their bulgur making suitability, the experiment was performed in NIFSAT, UAF in which characterization of wheat samples including (Durum-97, Punjab-11, Fakhar-e-Bhakkar 16, Anaj-17, Barani-17, Nifalama-KPK) were selected.  Verities assessed in thousand kernel weight, test weight, grain length, width and thickness. Compositional analysis of wheat showed differences among the cultivars for moisture, ash, crude protein, crude fat, crude fiber, NFE, Ca, Fe, Zn, Na and K. Based on compositional and grain characterization Fakhar-e-Bhakkar 16 was selected for the preparation of functional bulgur. Results indicated that phytochemical and organoleptic properties of functional bulgar showed the significant effect (p<0.05) among the treatments.

description: The line shape of the plasma resonance in both neutral and charged small sodium clusters is calculated. The overall properties of the multipeak structure observed in the photoabsorption cross section of spherical Na_8 and Na_20 neutral clusters can be understood in terms of Landau damping. Quantal configurations are shown to play an important role. In the case of charged Na_9+ and Na_21^+ clusters a single peak is predicted that carries most of the oscillator strength.
description: This early (1989) jellium matrix-RPA/LDA (TDLDA in Fock space) study: 1) introduced the physics of spectral Landau-damping fragmentation for metal clusters; 2) explained the double line of the neutral Na_20; 3) predicted a 25% strength at high energies (recently seen experimentally); 4) predicted reduced fragmentation for cationic clusters (later seen experimentally);

description: My research focuses on the mentality of catholic entrepreneurs and managers in Italy between the
1930's and the 1950's. The main source of my study is the archive of an organization called Unione
Cristiana Imprenditori Dirigenti [Christian Entrepreneurs and Managers Association], which was
founded in Milan in 1945 with the pedagogic intent to foster higher moral standards and social
responsibility in the milieux of catholic entrepreneurs, in the spirit of the Social Doctrine of the
Church. This experience was set in the social and political context of the Italian post-war years, but
it was also rooted in the debate â started during the 1930s - on the rise of a new catholic leadership
in society.
Essays in capital market equilibrium
Creators: name: Harris, Richard Glen
Publisher: name: University of British Columbia
Year: 2010

description: The thesis consists of three essays dealing with related problems of capital market equilibrium under conditions of uncertainty. The method of analysis is the construction and use of two period general equilibrium models. The first essay develops a set of necessary and sufficient conditions, for the determination of equilibrium prices in the well-known Capital Asset Pricing model. A number of structural properties of the equilibrium are determined and applied in investigation of the comparative statics of the model. In particular, the effect on equilibrium prices of changes in the stochastic parameters and number of investors is established. The second essay deals with problems of financing and investment which occur when production and firms are added to the model. It is demonstrated that a "financial inconsistency" may arise as firms pursuing a particular objective, may attempt to invest more than the households in the economy are willing to finance. This possibility has implications for the existence of general equilibrium, admissable decision rules for firms, and the firm's problem of choosing a feasible financial policy. In order to deal with these issues a number of properties of the 'stock market economy' are established. The final essay relaxes the assumption, maintained in the first two essays, that all debt in the economy is default free. A number of simple capital market models are developed which determine an equilibrium interest rate on (risky) debt and an equilibrium probability of default. The comparative statics of these variables are investigated with respect to changes in the riskless rate of interest, the productivity of investment, the expectations of investors, and the transactions costs of default. It is shown that when equity is introduced, then provided bankruptcy is not costless, the market also determines an equilibrium debt/equity ratio.

description: Tunneling measurements on 2D electron gases at high magnetic field reveal a qualitative difference between the two spin sublevels of the lowest Landau level. While the tunneling current-voltage characteristic at filling factor $ν= 1/2$ is a single peak shifted from zero bias by a Coulomb pseudogap, the spectrum at $ν=3/2$ shows a well-resolved double peak structure. This difference is present regardless of whether $ν=1/2$ and $ν= 3/2$ occur at the same or different magnetic fields. No analogous effect is seen at $ν= 5/2$ and 7/2 in the first excited Landau level.

title: Role of Iron in the Mechanism of Asbestos-Induced Apoptosis in Human Lung and Pleural Target Cells
Creators: name: Baldys, Aleksander

description: Occupational exposure to asbestos has been associated with increased incidence of pulmonary interstitial fibrosis, mesothelioma of the pleura, and bronchogenic carcinoma. Although the mechanism by which asbestos causes cancer remains unknown , iron associated with asbestos is thought to play a role in the pathogenic effects of fibers.
The aim of this research was to examine and compare the asbestos-induced signaling phenomena in relevant human lung and pleural target cells, and to deter mine the role of iron from asbestos fibers in these events. Exposure of human airway epithelial (A549) cells, human pleural mesothelial (METSA) cells, and normal human small airway epithelial (SAEC) cells to asbestos resulted in a significant dephosphorylation and inactivation of epidermal growth factor receptor (EGFR). The effects of three types of asbestos, i.e. crocidolite, amosite and chrysotile, on the EGFR phosphorylation state in A549 cells appeared to be directly related to the amount of iron mobilized from these fibers. These results strongly suggest that iron plays an important role in asbestos induced inactivation of EGFR.
We observed that exposure of A549 and SAEC cells to crocidolite , but not inert titanium dioxide , led to a significant time- and dose-dependent inactivation of the main EGFR signaling pathways, including Akt and extracellular signal-regulated kinase 1/2 (ERKI/2) pathways. Crocidolite also initiated apoptosis via pathways involving activation of p38 mitogen-activated protein kinase (MAPK), caspase -3 and -9, and cleavage of poly(ADP-ribose) polymerase (PARP). Prevention of these effects with an iron chelator or endocytosis inhibitors strongly suggests that iron mobilized from fibers inside the cells initiates the observed events. Inhibition of p38 MAPK with SB203580 prevented inactivation of EGFR , inactivation of EGFR-associated survival pathways, and initiation of apoptosis. Our results also suggest that p38 MAPK-dependent protein serine/threonine phosphatase activation plays an important role in the observed phenomena. Taken together , it appears that iron-dependent p38 MAPK activation, through a serine/threonine phosphatase-mediated mechanism , regulates asbestos-induced apoptosis in human lung epithelial cells. We speculate that apoptosis of human lung target cells induced by asbestos fibers is a pathologic feature in lung injury and may account for some of the pulmonary toxicity of the fibers.

description: We analyze SU(2) invariant half-BPS states of the 3d \cN=8 or \cN=6 SCFT within the radial quantization of the ABJM theory, the theory proposed to describe N M2-branes in the R^3x C^4/Z_k background. After studying the classical moduli space of these configurations, we explicitly construct a set of gauge invariant operators involving 't Hooft monopole operators corresponding to these states. We show there is a one--to--one correspondence between the two sets carrying R-charge J and that they are labeled by Young tableaux of J boxes with a maximum of N rows. Restricting the full path integral to this half-BPS sector of the theory, we show the latter is described in terms of N fermions in a 2d harmonic potential in the sector of vanishing angular momentum. The same classification, though in the N to infinity limit, arise from the plane-wave (BMN) Matrix theory as well as the 11 dimensional LLM bubbling geometries, providing supportive evidence for the ABJM theory and/or the Matrix model.

description: We seek to evaluate the detection performance of a rapid primary screening tool of Covid-19 solely based on the cough sound from 8,380 clinically validated samples with laboratory molecular-test (2,339 Covid-19 positives and 6,041 Covid-19 negatives). Samples were clinically labeled according to the results and severity based on quantitative RT-PCR (qRT-PCR) analysis, cycle threshold, and lymphocytes count from the patients. Our proposed generic method is an algorithm based on Empirical Mode Decomposition (EMD) with subsequent classification based on a tensor of audio features and a deep artificial neural network classifier with convolutional layers called DeepCough'. Two different versions of DeepCough based on the number of tensor dimensions, i.e. DeepCough2D and DeepCough3D, have been investigated. These methods have been deployed in a multi-platform proof-of-concept Web App CoughDetect to administer this test anonymously. Covid-19 recognition results rates achieved a promising AUC (Area Under Curve) of 98.800.83%, sensitivity of 96.431.85%, and specificity of 96.201.74%, and 81.08%5.05% AUC for the recognition of three severity levels. Our proposed web tool and underpinning algorithm for the robust, fast, point-of-need identification of Covid-19 facilitates the rapid detection of the infection. We believe that it has the potential to significantly hamper the Covid-19 pandemic across the world.
