On the Quantum Mechanical State of the $Δ^{++}$ baryon

Subjects: subject: General Physics (physics.gen-ph)

description: The $Δ^{++}$ and the $Ω^-$ baryons have been used as the original reason for the construction of the Quantum Chromodynamics theory of Strong Interactions. The present analysis relies on the multiconfiguration structure of states which are made of several Dirac particles. It is shown that this property, together with the very strong spin-dependent interactions of quarks provide an acceptable explanation for the states of these baryons and removes the classical reason for the invention of color within Quantum Chromodynamics. This explanation is supported by several examples that show a Quantum Chromodynamics' inconsistency with experimental results. The same arguments provide an explanation for the problem called the proton spin crisis.

An examination of the impact of microcredit programmes at the intersections of gender and caste in North India
Creators: name: Sekhon, Sumeet
Publisher: name: University of British Columbia
Year: 2019

description: Microcredit, once hailed as the cure-all panacea for tackling poverty in the developing world, has become the subject of intense debate. Proponents assert that microcredit programmes help poor households to tackle economic shocks and build the entrepreneurial capacity of credit constrained clients, especially impoverished women in the developing world. They also point out that the nearly perfect loan repayment rates indicate the development of a structurally sound lending mechanism. On the other hand, naysayers call attention towards the inability of microcredit programmes to achieve sustainable reductions in poverty, to challenge the social construction of gender roles, and to increase the intra-household bargaining power of women. Moreover, providing credit to women may not lead to an improvement in their status if the other forms of access to markets, such as restricted mobility, gender biases, and time constraints due to their reproductive role, remain unchanged. Through my research, I address this debate by presenting and discussing my research findings from an examination of the impact of microcredit programmes on the status of women, particularly low-caste women, in rural Rajasthan, India. More specifically, I draw upon 46 interviews with women who are members of self-help groups, 21 interviews with corresponding male heads of households, and 6 key informant interviews. Study results show that most respondents viewed microcredit as a mere addition to their repository of credit sources—that is, an additional resource which could be used to meet regular household expenses, and, occasionally, to avert or endure a household crisis. However, there was an increase in the capacity of respondents to use their loans for larger expenses with increasing lengths of time spent in the programme. Furthermore, there were three significant pre-conditions for women to use their loans for productive purposes, as well as to exercise control over their loans: middle or old age, not residing with in-laws, and supportive or absent husbands.
Phase Transitions in Dissipative Quantum Transport and Mesoscopic Nuclear Spin Pumping

Publisher: name: arXiv

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)
subject: FOS: Physical sciences

description: Topological phase transitions can occur in the dissipative dynamics of a quantum system when the ratio of matrix elements for competing transport channels is varied. Here we establish a relation between such behavior in a class of non-Hermitian quantum walk problems [M. S. Rudner and L. S. Levitov, Phys. Rev. Lett. 102, 065703 (2009)] and nuclear spin pumping in double quantum dots, which is mediated by the decay of a spin-blockaded electron triplet state in the presence of spin-orbit and hyperfine interactions. The transition occurs when the strength of spin-orbit coupling exceeds the strength of the net hyperfine coupling, and results in the complete suppression of nuclear spin pumping. Below the transition point, nuclear pumping is accompanied by a strong reduction in current due to the presence of non-decaying "dark states" in this regime. Due to its topological character, the transition is expected to be robust against dephasing of the electronic degrees of freedom.
Activated Magnetospheres of Magnetars

Year: 2010
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: Like the solar corona, the external magnetic field of magnetars is twisted by surface motions of the star. The twist energy is dissipated over time. We discuss the theory of this activity and its observational status. (1) Theory predicts that the magnetosphere tends to untwist in a peculiar way: a bundle of electric currents (the "j-bundle") is formed with a sharp boundary, which shrinks toward the magnetic dipole axis. Recent observations of shrinking hot spots on magnetars are consistent with this behavior. (2) Continual discharge fills the j-bundle with electron-positron plasma, maintaining a nonthermal corona around the neutron star. The corona outside a few stellar radii strongly interacts with the stellar radiation and forms a "radiatively locked" outflow with a high e+- multiplicity. The locked plasma annihilates near the apexes of the closed magnetic field lines. (3) New radiative-transfer simulations suggest a simple mechanism that shapes the observed X-ray spectrum from 0.1 keV to 1 MeV: part of the thermal X-rays emitted by the neutron star are reflected from the outer corona and then upscattered by the inner relativistic outflow in the j-bundle, producing a beam of hard X-rays.

description: The project Massive Unseen Companions to Hot Faint Underluminous Stars from SDSS (MUCHFUSS) aims at finding hot subdwarf stars with massive compact companions like massive white dwarfs (M > 1.0 Msun), neutron stars or stellar mass black holes. The existence of such systems is predicted by binary evolution theory and recent discoveries indicate that they exist in our Galaxy. First results are presented for seven close binary sdBs with short orbital periods ranging from 0.21 d to 1.5 d. The atmospheric parameters of all objects are compatible with core helium-burning stars. The companions are most likely white dwarfs. In one case the companion could be shown to be a white dwarf by the absence of light-curve variations. However, in most cases late type main sequence stars cannot be firmly excluded. Comparing our small sample with the known population of close sdB binaries we show that our target selection method aiming at massive companions is efficient. The minimum companion masses of all binaries in our sample are high compared to the reference sample of known sdB binaries.

description: We study the crossover between thermal and shot-noise power in a chaotic quantum dot in the presence of non-ideal contacts at finite temperature. The result explicitly demonstrates that the temperature affect the suppression-amplification effect present in the main quantum noise. In particular, the weak localization contribution to the noise has an anomalous thermal behavior when one let the barriers vary, indicating the presence of a critical point related to specific value of the tunneling barriers. We also show how to get to the opaque limit of the quantum dot at finite temperature.

description: Generalizing the cyclically competing three-species model (often referred to as the rock-paper-scissors game), we consider a simple system of population dynamics without spatial structures that involves four species. Unlike the previous model, the four form alliance pairs which resemble partnership in the game of Bridge. In a finite system with discrete stochastic dynamics, all but 4 of the absorbing states consist of coexistence of a partner-pair. From a master equation, we derive a set of mean field equations of evolution. This approach predicts complex time dependence of the system and that the surviving partner-pair is the one with the larger product of their strengths (rates of consumption). Simulations typically confirm these scenarios. Beyond that, much richer behavior is revealed, including complicated extinction probabilities and non-trivial distributions of the population ratio in the surviving pair. These discoveries naturally raise a number of intriguing questions, which in turn suggests a variety of future avenues of research, especially for more realistic models of multispecies competition in nature.

description: We review recent developments in the theoretical investigation of the nucleon polarizabilities. We first report on the static polarizabilities as measured in real Compton scattering, comparing and interpreting the results from various theoretical approaches. In a second step, we extend the discussion to the generalized polarizabilities which can be accessed in virtual Compton scattering, showing how the information encoded in these quantities can provide a spatial interpretation of the induced polarization densities in the nucleon.

Thermodynamics of dense hadronic matter in a parity doublet model

description: We study thermodynamics of nuclear matter in a two-flavored parity doublet model within the mean field approximation. Parameters of the model are chosen to reproduce correctly the properties of the nuclear ground state. The model predicts two phase transitions in nuclear matter, a liquid-gas phase transition at normal nuclear density and a chiral transition at higher density. At finite temperature the pion decay constant exhibits a considerable reduction at intermediate values of chemical potential, which is traced back to the presence of the liquid-gas transition, and approaches zero at higher chemical potential associated with the chiral symmetry restoration. A "transition" from meson-rich to baryon-rich matter is also discussed.

Non-equilibrium thermodynamics analysis of rotating counterflow superfluid turbulence
Creators: name: Sciacca, Michele
Publisher: name: arXiv
Year: 2010
Subjects: subject: Other Condensed Matter (cond-mat.other)
subject: FOS: Physical sciences

description: In two previous papers two evolution equations for the vortex line density $L$, proposed by Vinen, were generalized to rotating superfluid turbulence and compared with each other. Here, the already generalized alternative Vinen equation is extended to the case in which counterflow and rotation are not collinear. Then, the obtained equation is considered from the viewpoint of non-equilibrium thermodynamics. According with this formalism, the compatibility between this evolution equation for $L$ and that one for the velocity of the superfluid component is studied. The compatibility condition requires the presence of a new term dependent on the anisotropy of the tangle, which indicates how the friction force depends on the rotation rate.

description: The annual rainfall uncertainty affects the available water. Therefore, in Thailand the available water during the dry season is the most important resources in rainfed areas for implementing the water management plan. Additionally, the most affected areas are in the rainfed areas since there is adeficiency of irrigation projects and water management plans. Consequently, the water balance process is necessary to predict the drought areas and prepare a mitigation plan. For this reason, the water balance process was applied to determine the water deficit areas at sub-district level in Thailand from 2019 to 2020. The water supplies were evaluated by measuring all the existing available water in rainfall-runoff, waterbodies, and watercourses. Furthermore, the water demands were calculated for domestic, agriculture, ecology, and industry sectors. The study results on water balance were in good agreement with drought areas as identified by the disaster management agency. Finally, we can conclude that the methodology used for this study is an efficient tool for the drought prediction at a sub-district level in the rainfed areas.
Tackling Higher Derivative Ghosts with the Euclidean Path Integral

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: An alternative to the effective field theory approach to treat ghosts in higher derivative theories is to attempt to integrate them out via the Euclidean path integral formalism. It has been suggested that this method could provide a consistent framework within which we might tolerate the ghost degrees of freedom that plague, among other theories, the higher derivative gravity models that have been proposed to explain cosmic acceleration. We consider the extension of this idea to treating a class of terms with order six derivatives, and find that for a general term the Euclidean path integral approach works in the most trivial background, Minkowski. Moreover we see that even in de Sitter background, despite some difficulties, it is possible to define a probability distribution for tensorial perturbations of the metric.

description: We consider the degree of conservation of nuclear spin polarization in the process of optical pumping under typical spin-exchange optical pumping conditions. Previous analyses have assumed that negligible nuclear spin precession occurs in the brief periods of time the alkali-metal atoms are in the excited state after absorbing photons and before undergoing quenching collisions with nitrogen molecules. We include excited-state hyperfine interactions, electronic spin relaxation in collisions with He and N_2, spontaneous emission, quenching collisions, and a simplified treatment of radiation trapping.

description: Recently, Kawai, Parrondo, and Van den Broeck have related dissipation to time-reversal asymmetry. We generalized the result by considering a protocol where the physical system is driven away from an initial thermal equilibrium state with temperature $β_0$ to a final thermal equilibrium state at a different temperature. We illustrate the result using a model with an exact solution, i.e., a particle in a moving one-dimensional harmonic well.

Effects of irrigation and agitation on apical vapor lock : an ex-vivo study
Creators: name: Farmand, Parisa
Publisher: name: University of British Columbia
Year: 2019

description: Objectives: 1- To detect the presence of apical vapor lock after positive pressure irrigation at two needle insertion depths. 2- To evaluate the elimination of apical vapor lock by manual dynamic agitation. 3- To investigate the replacement of the contrast solution with sodium hypochlorite at two needle insertion depths and flow rates. Methodology: Twenty-eight single rooted teeth were shaped with either Vortex Blue 25/04 or ProTaper Gold F2 (25/08) rotary files. Presence of apical vapor lock was detected radiograph-ically using a contrast mixture (sodium hypochlorite & cesium chloride) as the irrigant. Manual dynamic agitation with 50 strokes of a well fitting gutta percha cone was performed in teeth with apical vapor lock. Its elimination was then evaluated radiographically. In teeth in which apical vapor lock was eliminated, replacement of the contrast solution with sodium hypochlorite was assessed radiographically. Each tooth was then shaped with Vortex Blue 30/04 or ProTaper Gold F3 (30/09) rotary files and the aforementioned experiments were repeated. Results: Apical vapor lock was detected in 92.0% of the samples. Manual dynamic agitation eliminated the apical vapor lock in 81.6% of the teeth. Apical vapor lock was more likely to be present and eliminated in teeth that were shaped with ProTaper Gold rotary files. Increase in the flow rate, increase in the needle insertion depth, shaping with Vortex Blue rotary files and small-er apical preparation size improved the replacement of the contrast solution. Conclusion: Within the limitations of this study, shaping with ProTaper Gold rotary files has a joint effect in the formation and elimination of apical vapor lock. Replacement of the contrast solution with sodium hypochlorite was affected by the independent effects of needle insertion depth and flow rate and the joint effect of needle insertion depth, flow rate, rotary file system and apical size preparation.

Deterministic and stochastic modeling of the Min system for cell division
Creators: name: Jamieson-Lane, Alastair
Publisher: name: University of British Columbia
Year: 2019

description: The Min system acts as a key regulator for cell division in E. coli, repressing cell division at either end of the cell via pole to pole oscillation. Recent in vitro experiments have demonstrated the Min system's tendency to create ``burst'' patterning under suitable concentration conditions, whereby high concentration `bursts' of Min proteins nucleate from an approximately homogeneous background, before ``freezing'' and fading away. I start this thesis by giving a quick review of some of the complexities involved in modeling chemical reactions via Partial Differential Equations - particularly in 2D surfaces such as the cell membrane. I consider a number of toy models, demonstrating discrepancies between classical Reaction-Diffusion representations of chemical systems, and the more foundational particle system. These discrepancies are in most cases minor, in some cases extreme. A simplified Min model is developed, demonstrating how particle models of Min dynamics can lead to burst formation, even in cases where differential equations predict a uniform solution. Next, I take a recently developed and parameterized ODE model of the Min system based on experimental data from Ivanov et al, and extend the model to consider finite space, both on the membrane and in the volume of the cell. This extended model allows me to map out a bifurcation diagram of the system's behavior for concentrations both higher and lower than those used in the original data fitting, and explore the conditions under which burst nucleation is predicted. Finally, I show that white noise can allow a spatially distributed reaction diffusion system to escape from a neutrally stable steady state at zero, passing to some fixed value u(0,T)>0 in finite time. The most probable path to such a state leads to a narrow sharp spike reminiscent of experimental observations. Dynamics of this kind are typical whenever a system loses stability by passing slowly through a saddle node bifurcation.
Binary Evolution Constraints from Luminosity Functions of LMXBs

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: The formation and evolution of low-mass X-ray binaries (LMXBs) is not well understood. The properties of a population of LMXBs depend on a number of uncertain aspects of binary evolution, and population studies offers a relatively new way of probing binary interactions. We have studied the shape of the faint end of the X-ray luminosity function (LF) of LMXBs in nearby galaxies with Chandra and in the Milky Way using the Swift all-sky monitor. We find a clear difference between the LF of LMXBs in globular clusters (GCs) and those outside, with a relative lack of faint GC sources. This indicates a difference in the composition of the two populations.

description: We study the recently introduced ${\mathbb Z}_2$ pump consisting of a family of one-dimensional bulk insulators with time reversal restriction on the pumping cycle. We find that the scattering matrices of these pumps are dichotomized by a topological index. We show that the class of pumps characterized by a nontrivial topological index allows, in contrast to its topologically trivial counterpart, for the noiseless pumping of quantized spin, even in the absence of spin conservation. This distinction sheds light on the ${\mathbb Z}_2$ classification of two-dimensional time reversal invariant insulators.

Automatisierte Gestaltoptimierung von Bauteilen bezüglich ihres NVH-Verhaltens durch Geometriemorphing
Creators: name: Leupolz, Michael
Publisher: name: Karlsruher Institut für Technologie (KIT)
Year: 2020

description: Optimierung bezüglich des NVH-Verhaltens ist oftmals nur eingeschränkt möglich. Dies liegt unter anderem daran, dass der NVH-Optimierungsprozess häufig erst spät in der Produktentwicklung startet und somit bereits viele Restriktionen bezüglich des Designs bestehen. Gleichzeitig ist der Prozess, eine Gestalt mittels FE-Simulationsergebnissen zu optimieren, sehr zeitaufwendig. Eine Ursache dafür ist, dass zu betrachtende Designs mittels CAD erzeugt und neu vernetzt werden müssen. Dies macht umfangreiche Designstudien sehr zeit- und rechenaufwendig. Neuere Ansätze vermeiden diese iterative Vorgehensweise in der Produktentwicklung und greifen auf Mesh-Morphing-Methoden zurück. In dieser Arbeit wird das Box-Morphing Tool des Präprozessors ANSA verwendet. Anhand des Beispiels eines Radträgers wird eine Morphingstruktur entworfen, um dessen Lagersitze in drei Raumrichtungen zu verschieben. Der Morphingprozess läuft dabei vollständig automatisiert ab. Zur Erstellung der betrachteten Geometrievariationen wird ein Arbeitsablauf in der Optimierungsumgebung Optislang aufgebaut. Diese dient ebenfalls zur Identifikation der optimalen Geometrie sowie zur Ermittlung eines analytischen Metamodells. Die Evaluierung jeder Geometrie basiert auf einer Bewertungsgröße, welche aus Übertragungsfunktionen berechnet wird. Diese Arbeit zeigt somit einen ganzheitlichen Prozess zur Gestaltoptimierung auf, der nahezu kein manuelles Eingreifen erfordert. Der Arbeitsablauf sowie Teilfunktionen des implementierten Morphing-Scriptes können dabei problemlos auf andere Geometrien übertragen werden.

Accretion through the inner hole of transitional disks: What happens to the dust?

Publisher: name: arXiv
Year: 2011
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: We study the effect of radiation pressure on the dust in the inner rim of transitional disks with large inner holes. In particular, we evaluate whether radiation pressure can be responsible for keeping the inner holes dust-free, while allowing gas accretion to proceed. This has been proposed in a paper by Chiang and Murray-Clay (2007, Nature Physics 3, p. 604) who explain the formation of these holes as an inside-out evacuation due to X- ray-triggered accretion of the innermost layer of the disk rim outside of the hole. We show that radiation pressure is clearly incapable of stopping dust from flowing into the hole because of dust pile-up and optical depth effects, and also because of viscous mixing. Other mechanisms need to be found to explain the persistence of the opacity hole in the presence of accretion, and we speculate on possible solutions.

description: The 11-year activity cycle of the Sun is a consequence of a dynamo process occurring beneath its surface. We analyzed photometric data obtained by the CoRoT space mission, showing solar-like oscillations in the star HD49933, for signatures of stellar magnetic activity. Asteroseismic measurements of global changes in the oscillation frequencies and mode amplitudes reveal a modulation of at least 120 days, with the minimum frequency shift corresponding to maximum amplitude as in the Sun. These observations are evidence of a stellar magnetic activity cycle taking place beneath the surface of HD49933 and provide constraints for stellar dynamo models under conditions different from those of the Sun.

description: The β-barrel assembly machinery (BAM) is a multimeric protein complex responsible for the folding of outer membrane proteins in gram-negative bacteria. It is essential for cell survival and outer membrane integrity. Therefore, it is of impact in the context of antibiotic resistance and can serve as a target for the development of new antibiotics. The interaction between two of its subunits, BamA and BamD, is essential for its function. Here, a FRET-based assay to quantify the affinity between these two proteins in living bacterial cells is presented. The method was applied to identify two interaction hotspots at the binding interface. BamDY184 was identified to significantly contribute to the binding between both proteins through hydrophobic interactions and hydrogen bonding. Additionally, two salt bridges formed between BamDR94, BamDR97, and BamAE127 contributed substantially to the binding of BamA to BamD as well. Two peptides (RFIRLN and VAEYYTER) that mimic the amino acid sequence of BamD around the identified hotspots were shown to inhibit the interaction between BamA and BamD in a dose-dependent manner in the upper micromolar range. These two peptides can potentially act as antibiotic enhancers. This shows that the BamA–BamD interaction site can be addressed for the design of protein–protein interaction inhibitors. Additionally, the method, as presented in this study, can be used for further functional studies on interactions within the BAM complex.

description: We present Spitzer 3.6--24 micron photometry and spectroscopy for stars in the 1--3 Myr-old Coronet Cluster, expanding upon the survey of Sicilia-Aguilar et al. (2008). Using sophisticated radiative transfer models, we analyze these new data and those from Sicilia-Aguilar et al. (2008) to identify disks with evidence for substantial dust evolution consistent with disk clearing: transitional disks. We then analyze data in Taurus and others young clusters -- IC 348, NGC 2362, and eta Cha -- to constrain the transitional disk frequency as a function of time. Our analysis confirms previous results finding evidence for two types of transitional disks -- those with inner holes and those that are homologously depleted. The percentage of disks in the transitional phase increases from ~ 15--20% at 1--2 Myr to > 50% at 5--8 Myr; the mean transitional disk lifetime is closer to ~ 1 Myr than 0.1--0.5 Myr, consistent with previous studies by Currie et al. (2009) and Sicilia-Aguilar et al. (2009). In the Coronet Cluster and IC 348, transitional disks are more numerous for very low-mass M3--M6 stars than for more massive K5--M2 stars, while Taurus lacks a strong spectral type-dependent frequency. Assuming standard values for the gas-to-dust ratio and other disk properties, the lower limit for the masses of optically-thick primordial disks is Mdisk ~ 0.001--0.003 M*. We find that single color-color diagrams do not by themselves uniquely identify transitional disks or primordial disks. Full SED modeling is required to accurately assess disk evolution for individual sources and inform statistical estimates of the transitional disk population in large samples using mid-IR colors.
