description: Using the hierarchy picture of the fractional quantum Hall effect, we study the the ground state periodicity of a finite size quantum Hall droplet in a quantum Hall fluid of a different filling factor. The droplet edge charge is periodically modulated with flux through the droplet and will lead to a periodic variation in the conductance of a nearby point contact, such as occurs in some quantum Hall interferometers. Our model is consistent with experiment and predicts that superperiods can be observed in geometries where no interfering trajectories occur. The model may also provide an experimentally feasible method of detecting elusive neutral modes and otherwise obtaining information about the microscopic edge structure in fractional quantum Hall states.

description: Direct sampling of interstellar neutral (ISN) atoms close to the Sun enables studies of the very local interstellar medium (VLISM) around the heliosphere. The primary population of ISN helium atoms has, until now, been assumed to reflect the pristine VLISM conditions at the heliopause. Consequently, the atoms observed at 1 au by the Interstellar Boundary Explorer (IBEX) were used to determine the VLISM temperature and velocity relative to the Sun, without accounting for elastic collisions with other species outside the heliopause. Here, we evaluate the effect of these collisions on the primary ISN helium population. We follow trajectories of helium atoms and track their collisions with slowed plasma and interstellar hydrogen atoms ahead of the heliopause. Atoms typically collide a few times in the outer heliosheath, and only ~1.5% of the atoms are not scattered at all. We use calculated differential cross sections to randomly choose scattering angles in these collisions. We estimate that the resulting primary ISN helium atoms at the heliopause are slowed down by ~0.45 km/s and heated by ~1100 K compared to the pristine VLISM. The resulting velocity distribution is asymmetric and shows an extended tail in the antisunward direction. Accounting for this change in the parameters derived from IBEX observations gives the Sun's relative speed of 25.85 km/s and temperature of 6400 K in the pristine VLISM. Finally, this paper serves as a source of the differential cross sections for elastic collisions with helium atoms.

description: We investigate the strange particle composition of the early Universe in the hadron epoch $T_h\approx 150\ge T\ge 10$\,MeV. We study strangeness yield in thermal and chemical equilibrium constrained by prescribed entropy per baryon in a charge neutral and strangeness neutral $\langle s-\bar s\rangle$ Universe. Turning to kinetic processes in a Hubble expanding Universe, we determine conditions at which individual strangeness producing reactions fall out of detailed balance between decay and back-reaction strangeness production rates in presence of decreasing temperature $T$; we allow for weak, electromagnetic, and strong interaction processes. The weak interaction $μ^\pm+ν_μ\rightarrow K^\pm$ freezeout is at $T_f^{K^\pm}=33.8\,\mathrm{MeV}$; the electromagnetic process $l^-+l^+\rightarrowϕ$ freezeout is at $T_f^ϕ=23\sim25\,\mathrm{MeV}$; and the hadronic reaction $π+π\rightarrow K$ freezeout is at $T_f^K=19.8\,\mathrm{MeV}$.

description: We report the first quasioptical simulations of wave beams in a hot plasma using the quasioptical code PARADE (PAraxial RAy DEscription) [Phys. Plasmas 26, 072112 (2019)]. This code is unique in that it accounts for inhomogeneity of the dissipation-rate across the beam and mode conversion simultaneously. We show that the dissipation-rate inhomogeneity shifts beams relative to their trajectories in cold plasma and that the two electromagnetic modes are coupled via this process, an effect that was ignored in the past. We also propose a simplified approach to accounting for the dissipation-rate inhomogeneity. This approach is computationally inexpensive and simplifies analysis of actual experiments.

description: This PhD Thesis focuses on how aroma profile in crops is affected by agronomic and genetic variables. In the first chapter we considered the effects of salt stress on main morphological and physiological traits of two cultivars of sweet basil (Genovese and Napoletano) Specifically, we focused on compositional changes in aroma profile and their possible significance in adaptation and tolerance to the oxidative stress.
In the second chapter, we considered the aroma profile of two chilli pepper species, Habanero (Capsicum chinenese) and Jalapeño (Capsicum Annuum), at different stages of maturity. Moreover, preliminary results of genetic mapping process were introduced.
Part of this research has been conducted at University of California-Davis (USA).

description: We obtain exact results in α' for open and closed A-model topological string amplitudes on a large class of toric Calabi-Yau threefolds by using their correspondence with five dimensional gauge theories. The toric Calabi-Yau's that we analyze are obtained as minimal resolution of cones over Y(p,q) manifolds and give rise via M-theory compactification to SU(p) gauge theories on R^4 x S^1. As an application we present a detailed study of the local F_2 case and compute open and closed genus zero Gromov-Witten invariants of the C^3/Z_4 orbifold. We also display the modular structure of the topological wave function and give predictions for higher genus amplitudes.The mirror curve in this case is the spectral curve of the relativistic A_1 Toda chain. Our results also indicate the existence of a wider class of relativistic integrable systems associated to generic Y(p,q) geometries.

Year: 2009

description: Un importante ausilio alla diagnosi e alla stadiazione delle neoplasie ossee è offerto dalle tecniche di Diagnostica per Immagini. L’esame radiografico rappresenta tuttora l’esame di scelta, sia perché, essendo una tecnica basata sui raggi X, è in grado di fornire utili informazioni sulle strutture ossee, sia per la facilità dell’esecuzione e per i costi ridotti. Altre tecniche di Imaging quali la Tomografia Computerizzata (TC),
l’ecografia (US), la Risonanza Magnetica (RM) e la Scintigrafia Ossea, consentono una migliore valutazione della lesione primaria, del coinvolgimento dei tessuti molli adiacenti, delle strutture linfonodali annesse e la ricerca di metastasi.
Lo scopo di questa tesi è di valutare gli aspetti radiografici, ecografici e TC delle neoplasie ossee primarie dei pazienti giunti al Centro Interdipartimentale di Radiologia Veterinaria dell’Università “Federico II” di Napoli negli ultimi 10 anni, correlando la diagnosi delle tecniche di Imaging da noi utilizzate a quella cito-istopatologica e/o necroscopica. E’ stato aggiunto uno studio epidemiologico descrittivo per valutare la prevalenza delle neoplasie ossee primarie nel nostro bacino di utenza in base al sesso, alla razza e all’età dei soggetti del nostro campione. La prevalenza è stata valutata rapportando il campione dei soggetti affetti al campione totale dei cani pervenuti al nostro Centro nel periodo considerato.

description: Twisted quantum field theories on the Groenewold-Moyal plane are known to be non-local. Despite this non-locality, it is possible to define a generalized notion of causality. We show that interacting quantum field theories that involve only couplings between matter fields, or between matter fields and minimally coupled U(1) gauge fields are causal in this sense. On the other hand, interactions between matter fields and non-abelian gauge fields violate this generalized causality. We derive the modified Feynman rules emergent from these features. They imply that interactions of matter with non-abelian gauge fields are not Lorentz- and CPT-invariant.

description: Superbursts are long duration, rare, and extremely energetic thermonuclear explosions of neutron star low-mass X-ray binaries (NS LMXBs), which are proposed to be due to unstable carbon ignition. We report the superburst properties and consequences from Aql X-1 observed by the Neutron Star Interior Composition Explorer (NICER), the Monitor of All-sky X-ray Image, Swift, and Insight Hard X-ray Modulation Telescope (Insight-HXMT) on the MJD 59130.7. We found two faint type I X-ray bursts 9.44 days after the superburst with a short recurrence time of 7.6 minutes, which is the most accurate measurement of the quenching time in all NS LMXBs with observed superbursts. We also discovered mHz quasi-periodic oscillations in the frequency range 2.7--11.3 mHz immediately after the superburst, before and after the resumption of the first type I X-ray burst from NICER, Swift, and Insight-HXMT observations. For the first time, we observed the transition from superburst, via marginally stable burning to unstable burning in NS LMXBs. We compared the quenching time and the recurrence time of type I X-ray bursts with simulations.

description: Education is essential to life as it engines growth and development in any society (Olaniyan & Okemakinde, 2008). As the COVID-19 pandemic unfolds, students are bound to a transition from classroom to remote learning. While students may benefit from this transition, increasing levels of stress suggest a difficulty to cope with remote learning. What obstacles prevent students to practice self-regulated learning: doing what they intend to do? Consequently, what strategies will help students become learners that are more independent?

A study of the role of the works of art in two novels by Michel Butor
Creators: name: Fuller, Margaret M.
Publisher: name: University of British Columbia
Year: 2010

description: In L'Emploi du temps (1956) and La Modif ication (1957) Michel Butor continues the exploration of novelistic form begun in Passage de Milan (1954). In these and his later works, he seeks to answer the fundamental questions: What is the role of the novel as an art form? How do we represent time and space in the novel? A study of the works of art in L'Emploi du temps and La Modification, their role and their interrelationship with each other, with the central characters, and with the reader, shows how he explores these questions. For Butor the novel is a means of transforming the way in which we see the world and therefore of transforming the world. For, as the novelist experiments with new structures he creates new relationships which change our perception of "reality." The introduction of works of art - imaginary but based on some of the archetypal stories of western civilization (Theseus, Oedipus, Cain) in L’Empioi du 'temps, real (the Aeneid, the Sistine Ceiling, the Last Judgement) in La Modification - extends the temporal and spatial scope of the two novels. This allows Butor to create intricate structural patterns which in turn create complex interrelationships in the text. Through the works of art, the key periods of western civilization - ancient Greece and Rome, early Judaic and Christian times and the Renaissance - are restructured and re-presented to Jacques Revel, L6on Delmont and the reader. In this re-presentation, all the major artistic forms appear: tapestry, stained glass windows architecture, literature and film, in L'Emploi du temps; architecture, sculpture, painting and literature in La Modification. Music is absent from the content but present in the form of both novels whose mathematical structure, "reprises" of specific scenes or phrases and temporal flexibility find their origins in musical form. Butor's use of works of art and, through them, of myth and history demonstrates his view of the novel as an encyclopedic work whose purpose is to remind the reader of the ongoing influence of his cultural background and to involve him in the novelistic process. By restructuring the universal stories of mankind through the works of art and by demonstrating their influence on the stories of Jacques Revel and L6on Delmont, Butor shows us that in order to understand himself and his universe, modern man must explore, acknowledge and integrate his colelctive past. In Butor, this is accomplished through the act of writing.
Multipole Analysis of Kicks in Collision of Binary Black Holes

description: Thorne and Kidder give expressions which allow for analytical estimates of the "kick", it i.e. the recoil, produced from asymmetrical gravitational radiation during the interaction of black holes, or in fact any gravitating compact bodies. (The Thorne-Kidder formula uses momentum flux calculations based on the linearized General Relativity of gravitational radiation.) We specifically treat kicks arising in the binary interaction of equal mass black holes, when at least one of the black holes has significant spin, a. Such configurations can produce very large kicks in computational simulations. We consider both fly-by and quasicircular orbits. For fly-by orbits we find substantial kicks from those Thorne-Kidder terms which are linear in a. For the quasi-circular case, we consider in addition the nonlinear contribution (O(a^2)) to the kicks, and provide a dynamical explanation for such terms. However, in the cases of maximal kick velocities, the dependence on spin is largely linear (reproduced in numerical results).

description: (Conext:) Surveys of Wolf-Rayet (WR) populations in nearby galaxies provide tests of evolutionary models plus Type Ib/c supernova progenitors. This spectroscopic study complements the recent imaging survey of the spiral galaxy NGC 300 by Schild et al. (Aims): Revisions to the known WR content of NGC 300 are presented. We investigate the WR nature of candidate #41 from Schild et al. which is spatially coincident with the bright X-ray point source NGC 300 X-1; (Methods:) VLT/FORS2 multi-object spectroscopy of WR candidates in NGC 300 is obtained; (Results:) We establish an early-type WN nature of #41, i.e. similar to the optical counterpart of IC 10 X-1, which closely resembles NGC 300 X-1. We confirm 9 new WR stars, bringing the current WR census of the inner disk to 31, with N(WC)/N(WN)~0.9. (Conclusions:) If #41 is the optical counterpart for NGC 300 X-1, we estimate a WR mass of 38 Msun based upon ground-based photometry, from which a black hole mass of > 10 Msun results from the 32.8 hr period of the system and WR wind velocity of 1250 km/s. We estimate an 95% completeness among WC stars and 70% among WN stars, such that the total WR content is ~40, with N(WC)/N(WN)~0.7. From the Halpha-derived star formation rate of the inner galaxy, we infer N(WR)/N(O)~0.04

The measurement is based on an integrated luminosity of 320 pb-1, and includes events with jet multiplicity from >= 1 to >= 4. In each jet multiplicity sample the differential and cumulative cross sections with respect to the transverse energy of the n^(th)-leading jet are measured. For W+>=2 jets the differential cross section with respect to the 2-leading jets invariant mass m_(j_(1)j_(2)) and angular separation Delta R_(j_(1)j_(2)) is also reported. The data are compared to predictions from Monte Carlo simulations.

Creators: name: No Name Supplied
Publisher: name: Targum Association
Year: 1948

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.
Luminescence anomaly of dipolar valley excitons in homobilayer semiconductor moiré superlattices

description: In twisted homobilayer transition metal dichalcogenides, intra- and inter-layer valley excitons hybridize with the layer configurations spatially varying in the moiré. The ground state valley excitons are trapped at two high-symmetry points with opposite electric dipoles in a moiré supercell, forming a honeycomb superlattice of nearest-neighbor dipolar attraction. We find that the spatial texture of layer configuration results in a luminescence anomaly of the moiré trapped excitons, where a tiny displacement by interactions dramatically increases the brightness and changes polarization from circular to linear. At full filling, radiative recombination predominantly occurs at edges and vacancies of the exciton superlattice. The anomaly also manifests in the cascaded emission of small clusters, producing chains of polarization entangled photons. An interlayer bias can switch the superlattice into a single-orbital triangular lattice with repulsive interactions only, where the luminescence anomaly can be exploited to distinguish ordered states and domain boundaries at fractional filling.

description: We study an extension of the MSSM with a singlet S with coupling SH1H2 in order to solve the mu problem as in the NMSSM, and right-handed neutrinos N with couplings SNN in order to generate dynamically electroweak-scale Majorana masses. We show how in this model a purely right-handed sneutrino can be a viable candidate for cold dark matter in the Universe. Through the direct coupling to the singlet, the sneutrino can not only be thermal relic dark matter but also have a large enough scattering cross section with nuclei to detect it directly in near future, in contrast with most of other right-handed sneutrino dark matter models.

Molecular and functional characterization of the interaction between c-Myc and the MCM helicase
Creators: name: Ruggiero, Luca
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2006

description: The Myc genes (c-myc, n-myc, l-myc, s-myc) encode a family of protein that share structural an biological features and are conserved across all Metazoans. c-Myc, the most extensively studied of his family, has been found deregulated, at different level, in almost every kind of tumor. Originally described as a weak transcriptional activator, further studies disclosed uncommon features for an oncogene or a classic transcription factor. c-Myc exerts his influence on the cell growth, cell cycle progression, apoptosis, but the mechanisms that underlie these functions are still not well understood. In order to shed light on its role as master regulator of cell fate, we isolated the protein complex containing c-Myc. Among the molecular partners associated with c-Myc that were not described before, we have found Mcm7 and Mcm5. Mcm7 and Mcm5 are members of the MCM complex, a ring-shape structure composed by six proteins (Mcm2-7). They play a key role in DNA replication and are recently substituting the traditional tumor marker in clinical diagnosis. We have characterized the interaction between c-Myc and the entire MCM complex. Our studies seem to discard the possibility of a functional meaning of this interaction in c-Myc-mediated transcriptional activation, supporting the hypothesis of a direct effect of c-Myc in replication, already suggested by other authors.

description: The topological Hall effect is used extensively to study chiral spin textures in various materials. However, the factors controlling its magnitude in technologically-relevant thin films remain uncertain. Using variable temperature magnetotransport and real-space magnetic imaging in a series of Ir/Fe/Co/Pt heterostructures, here we report that the chiral spin fluctuations at the phase boundary between isolated skyrmions and a disordered skyrmion lattice result in a power-law enhancement of the topological Hall resistivity by up to three orders of magnitude. Our work reveals the dominant role of skyrmion stability and configuration in determining the magnitude of the topological Hall effect.

description: The prospect of identifying wormholes by investigating the shadows of wormholes constitute a foremost source of insight into the evolution of compact objects and it is one of the essential problems in contemporary astrophysics. The nature of the compact objects (wormholes) plays a crucial role on shadow effect, which actually arises during the strong gravitational lensing. Current Event Horizon Telescope observations have inspired scientists to study and to construct the shadow images of the wormholes. In this work, we explore the shadow cast by a certain class of rotating wormhole. To search this, we first compose the null geodesics and study the effects of the parameters on the photon orbit. We have exposed the form and size of the wormhole shadow and have found that it is slanted as well as can be altered depending on the different parameters present in the wormhole spacetime. We also constrain the size and the spin of the wormhole using the results from M87* observation, by investigating the average diameter of the wormhole as well as deviation from circularity with respect to the wormhole throat size. In a future observation, this type of study may help to indicate the presence of a wormhole in a galactic region.

description: We calculate the GeV spectra of GRB afterglows produced by inverse Compton scattering of the sub-MeV emission of these objects. We improve on earlier treatments by using refined afterglow parameters and new model developments motivated by recent Swift observations. We present time-dependent GeV spectra for standard, constant parameter models, as well as for models with energy injection and with time-varying parameters, for a range of burst parameters. We evaluate the limiting redshift to which such afterglows can be detected by the GLAST LAT, as well as AGILE.

description: The development of analytic-gradient methodology for excited states within conventional time-dependent density-functional theory (TDDFT) would seem to offer a relatively inexpensive alternative to better established quantum-chemical approaches for the modeling of photochemical reactions. However, even though TDDFT is formally exact, practical calculations involve the use of approximate functionals, in particular the TDDFT adiabatic approximation, whose use in photochemical applications must be further validated. Here, we investigate the prototypical case of the symmetric CC ring opening of oxirane. We demonstrate by direct comparison with the results of high-quality quantum Monte Carlo calculations that, far from being an approximation on TDDFT, the Tamm-Dancoff approximation (TDA) is a practical necessity for avoiding triplet instabilities and singlet near instabilities, thus helping maintain energetically reasonable excited-state potential energy surfaces during bond breaking. Other difficulties one would encounter in modeling oxirane photodynamics are pointed out but none of these is likely to prevent a qualitatively correct TDDFT/TDA description of photochemistry in this prototypical molecule.

description: We study various properties of an ultracold two-dimensional (2D) Bose gas that are beyond a mean-field description. We first derive the effective interaction for such a system as realized in current experiments, which requires the use of an energy dependent $T$-matrix. Using this result, we then solve the mean-field equation of state of the modified Popov theory, and compare it with the usual Hartree-Fock theory. We show that even though the former theory does not suffer from infrared divergences in both the normal and superfluid phases, there is an unphysical density discontinuity close to the Berezinskii-Kosterlitz-Thouless transition. We then improve upon the mean-field description by using a renormalization group approach and show how the density discontinuity is resolved. The flow equations in two dimensions, in particular, of the symmetry-broken phase, already contain some unique features pertinent to the 2D XY model, even though vortices have not been included explicitly. We also compute various many-body correlators, and show that correlation effects beyond the Hartree-Fock theory are important already in the normal phase as criticality is approached. We finally extend our results to the inhomogeneous case of a trapped Bose gas using the local-density approximation and show that close to criticality, the renormalization group approach is required for the accurate determination of the density profile.

description: We show that thin film CdTe solar cells exhibit the phenomenon of threshold switching similar to that in phase change and resistive memory. It creates a conductive filament (shunt) through the solar cell reaching the buried electrode, such as the transparent conductive oxide (TCO) in CdTe based photovoltaics (PV). While in the existing PV the buried electrode was routinely contacted via laser scribe filled metals, our work paves a way to an alternative technology of no-scribe PV.

Inferior performance, standards, and expectations in task-oriented same-sex dyads
Creators: name: Freeman, Sabrina Karen
Publisher: name: University of British Columbia
Year: 2010

description: This research examines the role of standards in the formation of performance expectations. In particular, the formation of inferior performance expectations of an actor relative to a partner are examined. The theoretical framework used is that of expectation states theory which is concerned with the development, maintenance and modification of power and prestige hierarchies in task-oriented groups. Subjects in same-sex dyads were assigned at random to one of two experimental conditions. Two sets of standards defined the presence or absence of ability. In the first condition, subjects were given a lower score than their partners and were informed that it could not be determined from these scores whether they lacked ability at the task or whether the partner possessed the task ability. In the second condition, subjects were given the same scores as in condition one, but were told that they definitely lacked the task ability, and that the partner definitely possessed the ability. The hypothesis states that subjects in the first condition will reject less influence than those in the second. The hypothesis was supported for women, but not for men. Gender differences in rejection of influence rates cannot be attributed to manipulation failures or other variables also measured in the study. It is argued that lack of support for the hypothesis with respect to male subjects can be attributed to a greater degree of caution amongst males in the formation of expectations based upon evaluations of past performance. Reasons for male reluctance in generalizing from information provided are suggested and the importance of these findings to expectation states theory and to the general role of standards is discussed.

description: We consider modified gravity cosmological models that can be transformed into two-field chiral cosmological models by the conformal metric transformation. For the $R^2$ gravity model with an additional scalar field and the corresponding two-field model with the cosmological constant and nonstandard kinetic part of the action, the general solutions have been obtained in the spatially flat FLRW metric. We analyze the correspondence of the cosmic time solutions obtained and different possible evolutions of the Hubble parameters in the Einstein and Jordan frames.

description: [ENGLISH] The research activity accounted for in this Ph.D. thesis belongs to the general field of electrical and electronic measurements. The attention is focused, in particular, on performance evaluation and troubleshooting of radiofrequency digital communication transmitters, a fundamental issue in applied research and industrial production of modern communication systems. Several measurements included in testing and troubleshooting procedures utilized by major manufacturers, or included in international standards, are taken into consideration. The original contribution consists in the development of original measurement methods, based on digital signal processing, which result more reliable, and/or repeatable, and/or efficient than the publicized ones. The proposed methods are based on digital signal processing, and operate in time, frequency, time-frequency and modulation domains.
Besides being based on rigorous methodological approaches, the proposed methods take advantage of an extensive experimental activity. All the proposed methods are extensively tested, by applying them to simulated, emulated and real communication signals. Measurement results are analyzed and compared to those achievable through the application of existing methods and/or instrumentation available on the market. / [ITALIANO] L’attività di ricerca oggetto della tesi rientra nel settore scientifico delle misure elettriche ed elettroniche, ed, in particolare, riguarda la valutazione delle prestazioni ed alla diagnostica dei trasmettitori digitali a radiofrequenza, una tematica centrale nell’ambito della ricerca applicata e della produzione industriale dei moderni sistemi di comunicazione.

description: Major active compounds from essential oils are well known to possess antimicrobial activity against both pathogen and spoilage microorganisms.
The aim of this work was (a)to determinate the alteration of the membrane fatty acid profile as an adaptive mechanism of the cells in presence of sublethal concentrations of antimicrobial compounds in response to a stress condition and (b) to evaluate the membrane damage of fatty acids profile caused by the exposition of the cells to high concentrations of the compounds.
Methanolic solutions of Thymol, Carvacrol, Limonen, Cinnamaldehyde and Eugenol were added into growing media of Escherichia coli O157:H7, Salmonella enterica serovar Typhimurium, Pseudomonas fluorescens, Brochothrix thermosphacta and Staphylococcus aureus strains. Fatty acid extraction and their gas-chromatographic analysis was performed to assess changing in membrane fatty acid composition. Substantial changes were observed on the long chain unsaturated fatty acids when the E. coli and Salmonella strain’s grew in presence of limonene and cinnamaldehyde and carvacrol and eugenol respectively. Brochothrix strain fatty acid profile was influenced by all compounds, while Pseudomonas and S. aureus strains didn’t show substantial changes in their fatty acids composition.
