description: We analyze high signal-to-noise spectrophotometric observations acquired simultaneously with TWIN, a double-arm spectrograph, from 3400 to 10400 Åof three star-forming regions in the HII galaxy SDSS J165712.75+321141.4. We have measured four line temperatures: Te([OIII]), Te([SIII]), Te([OII]), and Te([SII]), with high precision, rms errors of order 2%, 5%, 6% and 6%, respectively, for the brightest region, and slightly worse for the other two. The temperature measurements allowed the direct derivation of ionic abundances of oxygen, sulphur, nitrogen, neon and argon. We have computed CLOUDY tailor-made models which reproduce the O2+ measured thermal and ionic structures within the errors in the three knots, with deviations of only 0.1 dex in the case of O+ and S2+ ionic abundances. In the case of the electron temperature and the ionic abundances of S+/H+, we find major discrepancies which could be consequence of the presence of colder diffuse gas. The star formation history derived using STARLIGHT shows a similar age distribution of the ionizing population among the three star-forming regions. This fact suggests a similar evolutionary history which is probably related to a process of interaction with a companion galaxy that triggered the star formation in the different regions almost at the same time. The hardness of the radiation field mapped through the use of the softness parameter $η$ is the same within the observational errors for all three regions, implying that the equivalent effective temperature of the radiation fields are very similar for all the studied regions of the galaxy, in spite of some small differences in the ionization state of different elements.

description: Mastitis is one of the costliest diseases in the dairy cattle industry. Environmental pathogens, such as Streptococcus uberis (Strep. uberis), are the most prevalent causes of mastitis infections, while contagious pathogen mastitis has declined in incidences due to improvement in management protocols. Antimicrobials and antibiotics are the primary therapies currently utilized in the dairy industry to treat mastitis. However, the concern for antibiotic overuse and potential bacterial resistance due to improper use of these therapies has steered research in exploration of alternatives to antibiotics or other strategies. One potential alternative is supplementation of an immunomodulatory feed additive to daily cattle total mixed rations (TMR). A current immunomodulator is OmniGen-AF ® (OMN) produced by Phibro Animal Health Corporation (Teaneck, NJ) and has been explored being fed to lactating dairy cattle by previous research groups. OmniGen- AF ® has been reported to improve initial innate immune response during infection. However, it is unknown how OMN influences the innate immune system in vivo to a S. uberis mastitis infection. The ability of OMN to modulate immune function during an environmental mastitis infection was tested compared to control groups. Cows fed OmniGen-AF® and challenged with Strep. uberis had numerically higher least squared mean Log somatic cell count compared to the control group that was not fed OMN and challenged with Strep. uberis. OMN fed cows displayed numerically higher average daily feed intake and fluid milk yield values compared to the control group. Further analysis of milk and blood samples using immunoassays to monitor the effects OMN has on cytokine and cortisol levels throughout mastitis infection is needed to determine innate immune response. In conclusion, OmniGen-AF® has the potential as an immunomodulator that improves innate immune system activity with continuous supplementation in the diet to prevention of dairy cattle environmental mastitis.

description: Several classes of gravitational backgrounds in $3+1$ dimensions have been proposed as holographic duals to Lifshitz-like theories describing critical phenomena in $2+1$ dimensions with critical exponent $z\geq 1$. We numerically explore one such model, characterized by a temperature $T$ and chemical potential $μ$, and find how to embed these solutions into AdS for a range of values of $z$. We find no phase transition going from the $T\llμ$ to the $T\gg μ$ regimes, and find that the solutions smoothly interpolate between the Lifshitz-like behavior and the relativistic AdS-like behavior. Finally, we exploit some conserved quantities to find a relationship between the energy density $\mc E$, entropy density $s$, and number density $n$, $\mc E=\frac{2}{3} \left(Ts+μn\right)$. We show that this result is expected from general scaling arguments, and generalizes to $\mc E= \frac{d}{d+1}\left(Ts+μn\right)$ for a theory dual to AdS$_{d+2}$ (Poincaré patch) asymptotics with a local $U(1)$ gauge invariance.

description: We consider a stochastic process $Y$ defined by an integral in quadratic mean of a deterministic function $f$ with respect to a Gaussian process $X$, which need not have stationary increments. For a class of Gaussian processes $X$, it is proved that sums of properly weighted powers of increments of $Y$ over a sequence of partitions of a time interval converge almost surely. The conditions of this result are expressed in terms of the $p$-variation of the covariance function of $X$. In particular, the result holds when $X$ is a fractional Brownian motion, a subfractional Brownian motion and a bifractional Brownian motion.

Observations and Models of Eclipsing Binary Systems: RT And, TU Boo, KV Gem, UU Lyn, MY Cyg, KR Per, RU Eri, and YY Cet

Year: 2010
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: Eclipsing binary systems form the fundamental basis of Astronomy in the sense that they are the primary means to determine fundamental stellar astrophysical quantities such as mass, radius, and temperature. Furthermore, they allow us to study the internal dynamos and resulting magnetic cycles of stars that we would normally only be able to study for one star, our Sun. The systems themselves are extremely interesting objects, consisting of a multitude of configurations that are tied together by a complex evolutionary history. Finally, they allow us to test theories of stellar structure and even General Relativity. Thus the accurate observation and modeling of these systems is of great importance to the field. The first three chapters of this thesis are devoted to acquainting a reader with a general science background, but no knowledge of Astronomy, to eclipsing binaries and the field in general, and should provide the reader with an adequate background to understand the rest of the thesis. The subsequent eight chapters are each devoted to the analysis of eight separate systems, (RT And, TU Boo, KV Gem, UU Lyn, MY Cyg, KR Per, RU Eri, and YY Cet), with each chapter arranged as would be generally found in a journal article. The collected data, models, and derived parameters for each system are analyzed in context to previous findings and general trends seen throughout the thesis. An evolutionary scenario for the formation of A and W type W Uma systems, with two types of near-contact systems as precursors and intermediates, is proposed.

description: The wider adoption of hydrogen in multiple sectors of the economy requires that safety and risk issues be rigorously investigated. Quantitative Risk Assessment (QRA) is an important tool for enabling safe deployment of hydrogen fueling stations and is increasingly embedded in the permitting process. However, QRA needs reliability data, and currently the available hydrogen safety databases are not in a format conducive for use in QRA. A review of the International Journal of Hydrogen Energy articles on hydrogen fueling station QRA found that lack of hydrogen reliability data is the most common knowledge gap in this field. This study explores what QRA and reliability data currently look like in the context of hydrogen systems. It then presents a new reliability data collection framework for hydrogen systems that overcomes gaps in existing hydrogen safety databases. Current hydrogen safety data collection tools, H2Tools, HIAD, NREL CDPs, and CHS are analyzed and compared for applicability to QRA. Lessons learned from these data collection tools are extracted and combined with best practices from reliability engineering to create an improved database framework for hydrogen reliability data. This framework aims to standardize the hydrogen fueling stations component hierarchy, failure mode taxonomy, and outline high level elements necessary for adequate reliability data collection suitable for use in QRA. This research establishes the groundwork for a collaborative hydrogen reliability database and the future development of data driven hydrogen safety tools.

Debate in the EFL Classroom: Seeking Improvements in Student Perspective-Taking Skills and Group Cohesion
Creators: name: Iadarola, Sara
Publisher: name: Scuola Universitaria della Svizzera Italiana (SUPSI)
Year: 2018

description: This project investigates the efficiency of debate in the EFL classroom as a means of developing students’ perspective taking skills, and increasing classroom cohesiveness. It aims to determine the degree to which debate can be beneficial to the quality of students’ interaction in class, as well as general improvement in group cohesion. In order to evaluate the effectiveness of debate, a five-week experiment was carried out in a thirdyear class at the Liceo in Mendrisio. Each lesson featured a different objective centered on didactic activities, culminating in a full classroom debate. Students were first introduced to the core concepts of argumentation and debate, from both structural and linguistic points of view. This introduction was followed by exploration of diametrically opposed views on a given subject, which in turn led to a debate in pairs, a group debate and a subsequent full-class debate. Questionnaires were provided to the class, (pre-test and post-test), as a means of assessing patterns of student interaction before and after the didactic experiment. Results were inconclusive, suggesting that debates did not demonstrably improve perspective taking abilities and class cohesion, yet not necessarily disproving the value of the debate-centered activities. In fact, while there have been some post-debate variations in the students’ patterns of interactions, there are not enough changes to conclusively state that debate increases student cohesion.

description: L’obiettivo di questo lavoro di diploma si prefigge di indagare se vi sono differenze tra adolescenti che frequentano il III ciclo di Scuola speciale cantonale rispetto ai coetanei di Scuola media, per quel che riguarda la possibilità e opportunità di scelta del vestito. L’indagine si estende anche sul ruolo simbolico dell’abbigliamento e sullo sviluppo identitario e la rappresentazione di sé e della propria immagine nei due gruppi selezionati. Il quadro teorico presenta i concetti utili per comprendere la necessità di un comportamento autodeterminato nello sviluppo dell’adolescente che riguardano: l’autonomia, lo sviluppo dell’immagine di sé, lo sviluppo dell’identità ed il legame con l’abbigliamento. Vi vengono descritti il contesto della Scuola speciale cantonale e l’allievo con disabilità intellettive e bisogni educativi speciali. Viene formulato il seguente interrogativo di ricerca: I ragazzi adolescenti con disabilità intellettive lieve-moderato che frequentano la Scuola speciale cantonale, hanno le stesse opportunità in termini di autonomia, di valore/importanza e di identificazione di scelta rispetto ai loro coetanei di Scuola media? Dalla discussione dei dati raccolti tramite il questionario sottoposto ai due gruppi campione emerge che le opportunità in termini di autonomia, di valore/importanza e di identificazione di scelta risultano essere in generale inferiori per gli allievi di Scuola speciale cantonale rispetto ai coetanei di Scuola media. Nella conclusione viene evidenziata l’importanza delle figure di riferimento dei ragazzi con disabilità, affinché esse promuovano fin dalla prima infanzia l’autonomia nelle scelte per favorire lo sviluppo dell’autodeterminazione e la costruzione di un sé indipendente.

description: The spectrum of temporal fluctuations of total magnetic energy for several dynamo models is different from white noise at frequencies smaller than the inverse of the turnover time of the underlying turbulent velocity field. Examples for this phenomenon are known from previous work and we add in this paper simulations of the G.O. Roberts dynamo and of convectively driven dynamos in rotating spherical shells. The appearance of colored noise in the magnetic energy is explained by simple phenomenological models. The Kolmogorov theory of turbulence is used to predict the spectrum of kinetic and magnetic energy fluctuations in the inertial range.
Formation of Kuiper Belt Binaries by Gravitational Collapse

description: A large fraction of 100-km-class low-inclination objects in the classical Kuiper Belt (KB) are binaries with comparable mass and wide separation of components. A favored model for their formation was capture during the coagulation growth of bodies in the early KB. Instead, recent studies suggested that large objects can rapidly form in the protoplanetary disks when swarms of locally concentrated solids collapse under their own gravity. Here we examine the possibility that KB binaries formed during gravitational collapse when the excess of angular momentum prevented the agglomeration of available mass into a solitary object. We find that this new mechanism provides a robust path toward the formation of KB binaries with observed properties, and can explain wide systems such as 2001 QW322 and multiples such as (47171) 1999 TC36. Notably, the gravitational collapse is capable of producing 100% binary fraction for a wide range of the swarm's initial angular momentum values. The binary components have similar masses (80% have the secondary-over-primary radius ratio >0.7) and their separation ranges from ~1,000 to ~100,000 km. The binary orbits have eccentricities from e=0 to ~1, with the majority having e<0.6. The binary orbit inclinations with respect to the initial angular momentum of the swarm range from i=0 to ~90 deg, with most cases having i<50 deg. Our binary formation mechanism implies that the primary and secondary components in each binary pair should have identical bulk composition, which is consistent with the current photometric data. We discuss the applicability of our results to the Pluto-Charon, Orcus-Vanth, (617) Patroclus-Menoetius and (90) Antiope binary systems.

description: Transmission spectroscopy at UV wavelengths is a rich and largely unexplored source of information about the upper atmospheres of extrasolar planets. So far, UV transit observations have led to the detection of atomic hydrogen, oxygen and ionized carbon in the upper atmosphere of HD209458b. The interpretation of these observations is controversial - it is not clear if the absorption arises from an escaping atmosphere interacting with the stellar radiation and stellar wind, or the thermosphere inside the Roche lobe. Here we introduce an empirical model that can be used to analyze UV transit depths of extrasolar planets and use it to interpret the transits of HD209458b in the H Ly alpha and the OI triplet emission lines. The results indicate that the mean temperature of the thermosphere is 8,000-11,000 K and that the H2/H dissociation front is located at pressures between 0.1-1 microbar, which correspond to an altitude of 1.1 Rp. The upper boundary of the model thermosphere is located at altitudes between 2.7-3 Rp, above which the atmosphere is mostly ionized. We find that the HI transit depth reflects the optical depth of the thermosphere in the wings of the H Ly alpha line but that the atmosphere also overflows the Roche lobe. By assuming a solar mixing ratio of oxygen, we obtain an OI transit depth that is statistically consistent with the observations. An OI transit depth comparable to or slightly larger than the HI transit depth is possible if the atmosphere is undergoing fast hydrodynamic escape, the O/H ratio is supersolar, or if a significant quantity of neutral oxygen is found outside the Roche lobe. Due to the large uncertainty in the data, repeated observations are necessary to better constrain the OI transit depths and thus the composition of the thermosphere.

description: We present Herschel/HIFI observations of the fundamental rotational transitions of ortho- and para-H$_2^{16}$O and H$_2^{18}$O in absorption towards Sagittarius~B2(M) and W31C. The ortho/para ratio in water in the foreground clouds on the line of sight towards these bright continuum sources is generally consistent with the statistical high-temperature ratio of 3, within the observational uncertainties. However, somewhat unexpectedly, we derive a low ortho/para ratio of $2.35 \pm 0.35$, corresponding to a spin temperature of $\sim$27~K, towards Sagittarius~B2(M) at velocities of the expanding molecular ring. Water molecules in this region appear to have formed with, or relaxed to, an ortho/para ratio close to the value corresponding to the local temperature of the gas and dust.

Points of General Relativisitic Shock Wave Interaction are "Regularity Singularities" where Spacetime is Not Locally Flat

description: We show that the regularity of the gravitational metric tensor in spherically symmetric spacetimes cannot be lifted from $C^{0,1}$ to $C^{1,1}$ within the class of $C^{1,1}$ coordinate transformations in a neighborhood of a point of shock wave interaction in General Relativity, without forcing the determinant of the metric tensor to vanish at the point of interaction. This is in contrast to Israel's Theorem which states that such coordinate transformations always exist in a neighborhood of a point on a smooth single shock surface. The results thus imply that points of shock wave interaction represent a new kind of singularity for perfect fluids evolving in spacetime, singularities that make perfectly good sense physically, that can form from the evolution of smooth initial data, but at which the spacetime is not locally Minkowskian under any coordinate transformation. In particular, at such singularities, delta function sources in the second derivatives of the gravitational metric tensor exist in all coordinate systems of the $C^{1,1}$ atlas, but due to cancelation, the curvature tensor remains uniformly bounded.

On the solar chromosphere observed at the limb with Hinode

description: Broad-band images in the Ca II H line, from the BFI instrument on the Hinode spacecraft, show emission from spicules emerging from and visible right down to the observed limb. Surprisingly, little absorption of spicule light is seen along their lengths. We present formal solutions to the transfer equation for given (ad-hoc) source functions, including a stratified chromosphere from which spicules emanate. The model parameters are broadly compatible with earlier studies of spicules. The visibility of Ca II spicules down to the limb in Hinode data seems to require that spicule emission be Doppler shifted relative to the stratified atmosphere, either by supersonic turbulent or organized spicular motion. The non-spicule component of the chromosphere is almost invisible in the broad band BFI data, but we predict that it will be clearly visible in high spectral resolution data. Broad band Ca II H limb images give the false impression that the chromosphere is dominated by spicules. Our analysis serves as a reminder that the absence of a signature can be as significant as its presence.

Epidemics on random intersection graphs

description: In this paper we consider a model for the spread of a stochastic SIR (Susceptible $\to$ Infectious $\to$ Recovered) epidemic on a network of individuals described by a random intersection graph. Individuals belong to a random number of cliques, each of random size, and infection can be transmitted between two individuals if and only if there is a clique they both belong to. Both the clique sizes and the number of cliques an individual belongs to follow mixed Poisson distributions. An infinite-type branching process approximation (with type being given by the length of an individual's infectious period) for the early stages of an epidemic is developed and made fully rigorous by proving an associated limit theorem as the population size tends to infinity. This leads to a threshold parameter $R_*$, so that in a large population an epidemic with few initial infectives can give rise to a large outbreak if and only if $R_*>1$. A functional equation for the survival probability of the approximating infinite-type branching process is determined; if $R_*\le1$, this equation has no nonzero solution, while if $R_*>1$, it is shown to have precisely one nonzero solution. A law of large numbers for the size of such a large outbreak is proved by exploiting a single-type branching process that approximates the size of the susceptibility set of a typical individual.

The coefficient of the $σ\cdot B$ term in the NRQCD action is computed at the one-loop level; the resulting shift of the hyperfine splitting of bottomonium is found to bring the lattice predictions in line with experiment.

Three essays on banks' financial stability: the role of off-balance sheet activities

description: This thesis includes three empirical studies that aim at evaluating the US bank holding companies’ (BHCs) financial soundness after the 2007-2009 Global Financial Crisis (GFC) through the lens of off-balance sheet (OBS) activities. First, it examines the implication of additional regulation and market scrutiny (stress testing) on banks’ adoption of OBS activities. Then, considering Risk-Based Capital (RBC) requirements under the Basel III accord, it assesses the presence of potential regulatory arbitrage. Second, this study examines the effects of OBS activities on default risk, considering the role of “too big to fail” (TBTF) banks, to assess differences in default risk between large and small banks. Finally, this research explores the effects of OBS activities on banks’ margins and profits under a low-for-long interest rate environment. The empirical analysis developed in each of the three studies provides the following results. First, the findings document a negative effect of stress tests on banks’ adoption of OBS activities, indicating that they are discouraged from engaging in OBS activities.Moreover, regulatory arbitrage behaviour is present for banks that are capital constrained. Second, OBS activities reduce default risk for small banks, suggesting diversification benefits. However, those activities increase default risk for TBTF banks, suggesting a moral hazard behaviour. That dynamic is reversed when incorporating the moderating effects of capital level: higher capital leads to safer OBS activities for TBTF banks, while more capital increases default risk for small banks through OBS channels. Third, the empirical evidence shows that banks’ margins are compressed to a greater extent than overall profits under a low interest rate environment. This adverse effect is more pronounced when a bank heavily engages in OBS activities, indicating cross-selling or an “originate-to-distribute” behaviour when low interest rates persist for an extended period of time. The main remarks highlighted by the empirical evidence provided in this thesis is that stress tests combined with RBC requirements serve as an effective tool to mitigate banks risk taking through the OBS channels and enhance TBTF banks financial soundness. However, moral hazard behaviour emerges when a TBTF bank is constrained by regulatory capital and interest rates near zero; low capitalised banks engage more in riskier OBS activities to avoid additional regulation and earn higher profits.
