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

description: Phase structure and phase transitions in dense QCD are studied using the Cornwall-Jackiw-Tomboulis (CJT) potential in the improved ladder approximation. The gap function, the condensation energy and the structure of Cooper pairs are investigated at finite temperature and density. Due to strong coupling effects at low densities, the gap, critical temperature and their ratio deviate from the weak coupling values. It is shown that the internal structure of Cooper pairs are robust against the thermal effects, despite the fact that the pairs are strongly correlated near the critical temperature. Also, the effect of the strange quark mass, Ms on the phase diagram is examined using a simple kinematical criterion. We discuss the behavior of the unlocking line, on which the CFL turns into the 2SC, through the variation of Ms.

Star formation and the environment of nearby field galaxies

description: We investigate the environmental dependence of galaxies with star formation from a volume-limited sample of 4782 nearby field galaxy spectra extracted from the 2dF Galaxy Redshift Survey final data release. The environment is characterized by the local spatial density of galaxies, estimated from the distance to the 5th nearest neighbour. Extensive simulations have been made to estimate correction factors for the local density due to sample incompleteness. We discriminate the galaxies in distinct spectral classes -- passive, star-forming, and short starburst galaxies -- by the use of the equivalent widths of [{\sc O ii}]$λ$3727 and H$δ$. The frequency of galaxies of different classes are then evaluated as a function of the environment. We show that the fraction of star-forming galaxies decreases with increasing density, whereas passive galaxies present the opposite behaviour. The fraction of short starburst galaxies -- that suffered a starburst at $\sim$ 200 Myr ago -- do not present strong environmental dependence. The fraction of this class of galaxies is also approximately constant with galaxy luminosity, except for the faintest bins in the sample, where their fraction seems to increase. We find that the star-formation properties are affected in all range of densities present in our sample (that excludes clusters), what supports the idea that star-formation in galaxies is affected by the environment everywhere. We suggest that mechanisms like tidal interactions, which act in all environments, do play a relevant role on the star-formation in galaxies.

description: We propose a radiative seesaw model based on a modular $A_4$ symmetry, which has good predictability in the lepton sector. We execute a numerical analysis to search for parameters that satisfy the experimental constraints such as those from neutrino oscillation data and lepton flavor violations. Then, we present several predictions in our model that originate from the modular symmetry at a fixed point as well as fundamental region of $τ$.

The young Hegel's conception of the unity of man
Creators: name: Boukhaf, Abderrahman
Publisher: name: American University
Year: 2023

description: This dissertation focuses on the writings of the young Hegel up to and including the Jena period. The treatment of these writings is pursued under the theme of the unity of man. The issue was commonly known human experience: philosophically, it was expressed by the spirit of the Enlightenment, especially its radical side, the philosophes. This was complicated by the inherent difficulties of the Critical Philosophy. In religion it was manifested in the conception of God as transcendent. This led to a relation of alienation between God and man. In politics this was shown in the state of "particularism" and the separation between man and the political institutions. Hence the lack of participation in political life. All these dimensions of fragmentation led to the emergence of a non-expressive form of life. The young Hegel did not deal with the issue of the unity of man in any systematic manner since most of his writings are fragments. Our proposal to study them under such a theme is probably the most convenient way of approaching this unexplored area of his philosophy in order to make sense out of it. Such as choice explains our methodology which can be characterized as thematic for it approaches these fragmentary writings under one theme; it is interpretive and this is dictated by the nature of the theme itself. It is, finally, historical since it deals with a collection of writings through a span of time. As the development of our theme proceeds, we see that Hegel gradually became aware of the need for a system as the only way to deal with the fragmented situation of man. However, this does not mean that he was successful and thus our finding shows the limitation of his endeavor; nevertheless, what we can still learn from him is the importance and the relevance of the issues he raised and the insightful claims he made.
The measurement of $θ_{13}$ and $δ$: the role of the uncertainties on the solar and atmospheric parameters

description: In this talk we show how the errors on solar and atmospheric parameters affect the measurement of the unknown PMNS parameters $θ_{13}$ and $δ$ at future LBL facilities. Performing three parameters fits in $θ_{13}$, $δ$ and, in turn, one of the atmospheric or solar parameters, we show that present uncertainties on $θ_{23}$ and $Δm^2_{23}$ worsen significantly the precision on ($θ_{13}$,$δ$) whereas the solar sector does not introduce further uncertainties. A precision on the atmospheric parameters similar to what expected at T2K-I is necessary to improve the sensitivities to $θ_{13}$ and $δ$.

description: We consider the Skyrme model using the explicit parameterization of the rotation group SO(3) through elements of its algebra. Topologically nontrivial solutions already arise even in the one-dimensional case because the fundamental group of SO(3) is Z_2. We explicitly find and analyze one-dimensional static solutions. Among them, there are topologically nontrivial solutions with finite energy among them. We propose a new class of projective models whose target spaces are arbitrary real projective spaces RP^d.

description: This dissertation attempts to expose the influence of Francis Bacon on the philosophy of Thomas Reid. Reid was a self-professed Baconian who viewed the human mind as a subject which was amenable to scientific investigation. Reid attempts to develop his own theory of mind according to the method of induction and experiment and general philosophy of science of Bacon. Further, Reid's use of the Baconian idols in his attack on the theory of ideas is explored. In addition, it is argued that this Baconian approach helps to illuminate Reid's direct realism in perception as well as Reid's indebtedness to Bacon in his treatment of sensations as a system of signs. Finally, Reid develops a theory of evidence and common sense which owes much to the legal discussion of the time. This again links Reid to Bacon who made a similar use of legal metaphors in defending his philosophy of science against scholastic apologists. By appealing to textual evidence in the works of both philosophers' writings and reconstructing Reid's positions in light of this influence, it is hoped that a better understanding of Reid's notion of common sense is ultimately reached as well as a solution to the problem of intentionality in Reid's theory of perception.

description: We prove that a certain genuine Hecke algebra $\mathcal{H}$ on the non-linear double cover of a simple, simply-laced, simply-connected, Chevalley group $G$ over $\mathbb{Q}_{2}$ admits a Bernstein presentation. This presentation has two consequences. First, the Bernstein component containing the genuine unramified principal series is equivalent to $\mathcal{H}$-mod. Second, $\mathcal{H}$ is isomorphic to the Iwahori-Hecke algebra of the linear group $G/Z_{2}$, where $Z_{2}$ is the $2$-torsion of the center of $G$. This isomorphism of Hecke algebras provides a correspondence between certain genuine unramified principal series of the double cover of $G$ and the Iwahori-unramified representations of the group $G/Z_{2}$.

description: The Zitterbewegung (ZB) effect is investigated in graphene with spacially modulated potential near the original Dirac point (ODP) and extra Dirac points (EDPs). Our calculations show that to get the large ZB oscillations, the wave packet center must be at the angle $θ_0=0$ for EDPs located at zero-energy, or $θ_0=π/2$ for both ODP and EDPs at finite energy $\varepsilon=mπ$ ($m$ integer). By varying the parameters ($q_2, \mathbb{V}$) of the periodic potential and the initial momentum ($κ_0, θ_0$) of Gaussian wave packet, it is found that the frequency of the ZB oscillations is in the range $[10^{7}~\text{Hz}, 10^{13}~\text{Hz}$] depending on what type of EDP is generated and the amplitude reaches hundreds of angstroms but their attenuation becomes very slow. More analysis of the frequency shows the possibilities in experimentally realizing the ZB effect in our system.

INTERNATIONAL MONETARY FUND STABILIZATION PROGRAMS AND INCOME DISTRIBUTION: COSTA RICA AND JAMAICA
Creators: name: Duncan, Jr., G. Cameron
Publisher: name: American University
Year: 2023

description: This study analyzes the impact of orthodox stabilization policies on income distribution in two small, open economies--Costa Rica and Jamaica. International Monetary Fund-supported stabilization programs have been criticized on the grounds that they ignored long-term development objectives, especially economic growth issues, while emphasizing short-term stabilization and balance of payments objectives. Critics of the Fund have concentrated for the most part on the short-run recessionary impacts of Fund programs. On the other hand, Fund cross-country studies show mixed impacts on economic growth and success in realizing current account and balance of payments improvements. This dissertation critiques the orthodox theory of stabilization--the 'monetary approach to the balance of payments'--and argues that the structuralist growth critique of the Fund is theoretically misplaced. Noting the gap in the theoretical and empirical literature with respect to the treatment of income distribution in the context of stabilization, the study investigates the distributive impact of Fund stabilization policies, i.e. fiscal, exchange rate, and wage policies, on the Costa Rican (1980-83) and Jamaican (1981-85) economies. The central method of inquiry is statistical analysis of official government data, supplemented by the non-standardized interviewing technique. The major findings are that: (1) in contrast to the Fund's goals, both countries experienced a sharp acceleration of inflation after Fund-imposed devaluations, while the balance of payments was brought into equilibrium; (2) consistent with the equity-oriented critique, there were declines in real wages, in the 'social wage', and in the wage share of national income, and a concentration of income during the stabilization period; and (3) there was evidence that poverty increased, and that orthodox policies tended to redistribute real income to agro-exporters at the expense of urban workers and small farmers who produced food for the domestic market. While the study focuses on the distribution of income during Fund programs, a secondary concern is the analysis of IMF influence on domestic policy making in Costa Rica and Jamaica and the Fund's interest in reorienting their development toward greater economic integration with the world market.

This is true in all models of ultrahigh energy (UHE) neutrino sources, in both $ν_e:ν_μ:ν_τ = 1:1:1$ and $ν_e:ν_μ:ν_τ = 1:2:0$ scenarios for the flux incident on earth. In particular the ratios of upward $μ$ events to upward shower events and the ratios of up events to down events are different by a factor of 2 to an order of magnitude in the comparisons between SM and LSG. $ν_τ$ rates are low but show high sensitivity to SM vs LSG interaction physics.

 Remarks. This genus was revised by Liang (1993). In this work Esakius chekiangensis Ouchi and P. transversa Lallemand and Synave, were synonymized with P. atricapilla (Distant). However, from an examination of the type of atricapilla from India (not examined by Liang, 1993) (®gure 11), this is diOEerent from the types of the other two species from China. Therefore, P. chekiangensis becomes a good species with P. transversa as its new junior synonym syn. nov. (see checklist). In the same work, Liang (1993) followed Lallemand’s (1949) unnecessary emendation of darjilingii to darjilingi.

description: This is a study of the status, roles and functions of the aged in aboriginal Cherokee society and contemporary Eastern Cherokee reservation life. The first part of this work focuses on an ethnohistorical reconstruction of the prestigious 'place' the so-called beloved men and beloved grandmothers occupied in pre-removal Cherokee tribal life. In the mid-nineteenth century, the Eastern Band of Cherokee Indians emerged as a new socio-political entity, no longer under the old religious gerontocracy, but still guided by the tribal elders. The second part of the study illustrates the nature and extent to which today's older tribal members, the senior citizens, participate in and contribute to family and community life. The picture emerging from field research contradicts the disengagement and reductionist theories of aging. Instead, it appears that, despite some limitations, the aged are still integrated members of Eastern Cherokee society which has maintained a positive cultural perception of and values associated with old age and the elderly.
The Circumstellar Environments of High-Mass Protostellar Objects I: Submillimetre Continuum Emission

description: We present maps of the 850 micron and 450 micron continuum emission seen towards a sample of 68 high-mass protostellar candidates with luminosities ranging from 10^2.5 to 10^5 solar luminosity. Most of these candidate high-mass stars are in the earliest stages of evolution, and have not yet developed an ultra-compact HII region. We observe a variety of continuum emission morphologies, from compact symmetric sources through to multiple cores embedded in long filaments of emission. We find on average there is a 65% probability of an IRAS point-source having a companion detection at submillimetre wavelengths. The ratio of integrated flux to peak flux for our detections shows no strong dependence on distance, suggesting the emission we have observed is primarily from scale-free envelopes with power-law density structures. Assuming a near kinematic distance projection, the clumps we detect vary in mass from ~1 to over 1000 solar mass, with a mean clump mass of 330 solar mass, column density of 9x10^23 cm^-2 and diameter of ~0.6 pc. The high luminosity and low mass of the smallest clumps suggests they are accompanied by a minimal number of stellar companions, while the most massive clumps may be examples of young protogroups and protoclusters. We measure the spectral index of the dust emission (alpha) and the spectral index of the dust grain opacity (beta) towards each object, finding clumps with morphologies suggestive of strong temperature gradients, and of grain growth in their dense inner regions. We find a mean value for beta of 0.9, significantly smaller than observed towards UCHII regions.

Supermassive Black Hole Mass Functions at Intermediate Redshifts from Spheroid and AGN Luminosity Functions

description: Redshift evolution of supermassive black hole mass functions (BHMFs) is investigated up to z ~ 1. BHMFs at intermediate redshifts are calculated in two ways. One way is from early-type galaxy luminosity functions (LFs); we assume an M_BH - L_sph correlation at a redshift by considering a passive evolution of L_sph in the local relationship. The resultant BHMFs (spheroid-BHMFs) from LFs of red sequence galaxies indicates a slight decrease of number density with increasing redshift at M_BH > 10^{7.5-8} M_solar. Since a redshift evolution in slope and zeropoint of the M_BH - L_sph relation is unlikely to be capable of making such an evolution in BHMF, the evolution of the spheroid-BHMFs is perhaps due mainly to the decreasing normalization in the galaxy LFs. We also investigate how spheroid-BHMFs are affected by uncertainties existing in the derivation in detail. The other way of deriving a BHMF is based on the continuity equation for number density of SMBHs and LFs of active galactic nucleus (AGN). The resultant BHMFs (AGN-BHMFs) show no clear evolution out to z = 1 at M_BH > 10^8 M_solar, but exhibit a significant decrease with redshift in the lower mass range. Comparison of the spheroid-BHMFs with the AGN-BHMFs suggests that at M_BH > 10^{8} M_solar, the spheroid-BHMFs are broadly consistent with the AGN-BHMFs out to z ~ 1. The agreement between the spheroid-BHMFs and the AGN-BHMFs appears to support that most of the SMBHs are already hosted by massive spheroids at z ~ 1 and they evolve without significant mass growth since then.

description: Abstract: Introduction: KRAS was one of the earliest human oncogenes to be described and is one of the most commonly mutated genes in different human cancers, including colorectal cancer. Despite KRAS mutants being known driver mutations, KRAS has proved difficult to target therapeutically, necessitating a comprehensive understanding of the molecular mechanisms underlying KRAS-driven cellular transformation. Objectives: To investigate the metabolic signatures associated with single copy mutant KRAS in isogenic human colorectal cancer cells and to determine what metabolic pathways are affected. Methods: Using NMR-based metabonomics, we compared wildtype (WT)-KRAS and mutant KRAS effects on cancer cell metabolism using metabolic profiling of the parental KRASG13D/+ HCT116 cell line and its isogenic, derivative cell lines KRAS+/– and KRASG13D/–. Results: Mutation in the KRAS oncogene leads to a general metabolic remodelling to sustain growth and counter stress, including alterations in the metabolism of amino acids and enhanced glutathione biosynthesis. Additionally, we show that KRASG13D/+ and KRASG13D/− cells have a distinct metabolic profile characterized by dysregulation of TCA cycle, up-regulation of glycolysis and glutathione metabolism pathway as well as increased glutamine uptake and acetate utilization. Conclusions: Our study showed the effect of a single point mutation in one KRAS allele and KRAS allele loss in an isogenic genetic background, hence avoiding confounding genetic factors. Metabolic differences among different KRAS mutations might play a role in their different responses to anticancer treatments and hence could be exploited as novel metabolic vulnerabilities to develop more effective therapies against oncogenic KRAS.

description: Some deep conjectures about quantum gravity are closely related to the role of symmetries in the gravitational background, especially for quantum black holes. In this paper, we systematically study the theory of quantum information for a charged, chaotic system. We show how the quantum information in the whole system has been represented by its charge sectors, using the theory of quantum chaos and quantum error correction, with concrete examples in the context of the complex SYK model. We discuss possible implications for black hole thought experiments and conjectures about quantum gravity in the dynamical setup. We believe this work will have potential applications from theories of quantum gravity to quantum simulation in quantum devices.

THE AGED IN PAST AND PRESENT EASTERN CHEROKEE SOCIETY
Creators: name: Marino, Cesare Rosario
Publisher: name: American University

description: This is a study of the status, roles and functions of the aged in aboriginal Cherokee society and contemporary Eastern Cherokee reservation life. The first part of this work focuses on an ethnohistorical reconstruction of the prestigious 'place' the so-called beloved men and beloved grandmothers occupied in pre-removal Cherokee tribal life. In the mid-nineteenth century, the Eastern Band of Cherokee Indians emerged as a new socio-political entity, no longer under the old religious gerontocracy, but still guided by the tribal elders. The second part of the study illustrates the nature and extent to which today's older tribal members, the senior citizens, participate in and contribute to family and community life. The picture emerging from field research contradicts the disengagement and reductionist theories of aging. Instead, it appears that, despite some limitations, the aged are still integrated members of Eastern Cherokee society which has maintained a positive cultural perception of and values associated with old age and the elderly.
SOVIET EMIGRE ARTISTS IN NEW YORK: ETHNICITY AND IDENTITY
Creators: name: Kelly, Jeanne A.
Publisher: name: American University
Year: 2023

description: In the 1970s and early 1980s a wave of mostly Jewish immigrants from the Soviet Union arrived in the U.S. Among this wave were a large number of artists, most of whom settled in New York City. This dissertation investigates the question of whether a separate identity tied to their cultural origin emerged among these artists. An ethnic group model combining two theoretical approaches was used to examine both social organizational and cultural-symbolic aspects of the artists' lives and work. Information was collected largely through open-ended, semi-structured interviews with 25 emigres, including dealers and critics, as well as from published materials. A study of the means by which the artists exhibited and sold their works revealed the existence of immigrant "brokers," who organized galleries and museums for the exclusive showing of the artists' work, arranged exhibits, and generally sought to promote the artists. It was found that while the brokers exploited certain images in attempting to formulate a distinct cultural identity for them, the artists themselves desired above all to gain individual recognition and approached the problem of organizing exhibits on a more fragmented and limited basis. The artists could be loosely grouped into two categories: those who painted or sculpted in early twentieth century styles and those open to contemporary trends. The former emphasized the desire to express eternal, universal truths; their art exhibited an orientation toward the inner world of emotions, the inner essence of objects, and for some, a metaphysical element. The latter saw as their mission to jolt viewers from conventional beliefs and to comment on current problems; their art is full of irony and satire. For a number the myths and images of Socialist Realism and Soviet propaganda are drawn on for this commentary. The dual approach adopted was found to be fruitful in illuminating both strategies used by the artists to achieve practical ends as well as the orienting beliefs underlying their approach to art making and cultural elements distinguishing their art.

Structure and distribution of arches in shaken hard sphere deposits

description: We investigate the structure and distribution of arches formed by spherical, hard particles shaken in an external field after they come to rest. Arches (or bridges) are formed during a computer-simulated, non-sequential deposition of the spheres after each shaking cycle. We identify these arches by means of a connectivity criterion and study their structural characteristics and spatial distribution. We find that neither the size distribution nor the shape of the arches is strongly affected by the packing fraction of the deposit. Conversely, the spatial distribution and orientation of the bridges do depend on the volume fraction occupied by the spheres.

Recombination of Intersecting D-branes in Tachyon Field Theory

Year: 2003
Subjects: subject: High Energy Physics - Theory (hep-th)

description: The mechanism of recombination of intersecting D-branes is investigated within the framework of effective tachyon field theory. We regard the branes as the kink-type tachyon condensed states and use the effective two-tachyon Lagrangian to study the off-diagonal fluctuations therein. It is seen that there is a tachyonic mode in the off-diagonal fluctuations, which signs the instability of the intersecting D-branes. We diagonalize the two-by-two tachyonic matrix field and see that the corresponding eigenfunctions could be used to describe the new recombined branes. Our prescription can be extended to discuss the general behavior of the recombination of intersection D-branes with arbitrary shapes. We present in detail the physical reasons behind the mathematical process of diagonalizing the tachyonic matrix field.

description: Quantum spin liquids (QSLs) form an extremely unusual magnetic state in which the spins are highly correlated and fluctuate coherently down to the lowest temperatures, but without symmetry breaking and without the formation of any static long-range-ordered magnetism. Such intriguing phenomena are not only of great fundamental relevance in themselves, but also hold the promise for quantum computing and quantum information. Among different types of QSLs, the exactly solvable Kitaev model is attracting much attention, with most proposed candidate materials, e.g., RuCl$_3$ and Na$_2$IrO$_3$, having an effective $S$=1/2 spin value. Here, via extensive first-principle-based simulations, we report the investigation of the Kitaev physics and possible Kitaev QSL state in epitaxially strained Cr-based monolayers, such as CrSiTe$_3$, that rather possess a $S$=3/2 spin value. Our study thus extends the playground of Kitaev physics and QSLs to 3$d$ transition metal compounds.
