description: We employ variational Monte Carlo methods to study the transition to strange matter in a simple one-dimensional string-flip model with two flavors and two colors of quarks. The dynamics of the system are described in terms of a many-body potential that confines quarks within hadrons, yet enables the hadrons to separate without generating unphysical long-range van der Waals forces. The model has ``natural'' low- and high-density limits: it behaves as a system of isolated hadrons at low density and as a Fermi gas of quarks at high density. We show that the system exhibits a transition to strange matter characterized by an increase in the length-scale for confinement. Yet the small increase at the transition region --- of only ten percent --- suggests that clustering correlations remain strong well into the strange-matter domain. Our results put into question descriptions of strange matter in terms of noninteracting, or weakly interacting, quarks.

description: Visual or auditory sensory deprivation represents a key model for studying experience-dependent plasticity. Different types of deprivations (congenital-late, temporary-permanent, peripheral-central)are characterized by a certain degree of perturbation of the typical sensory experience and can be represented in a three-dimensional space showing the distance from the typical experience. The dimensions are:(i) when the deprivation occurs, (ii) how long the deprivation lasts, and (iii) where is the barrier that causes the deprivation. Each dimension can be responsible for a low, medium, or high degree of perturbation. In thisdissertation, visual and auditory deprivation models are employed to investigate unisensory and multisensory neural plasticity. The first study (low degree of perturbation) aimed to unveil whether short-term monocular deprivation in the adult brain can induce neural plasticity beyond the visual system. The second study (medium degree of perturbation), using the model of temporary deprivation, assessed whether neural tracking of speech envelope could develop even in the absence of auditory stimulation from birth. Finally, the third study (high degree of perturbation) investigated how cerebral visual impairment affects visuospatial processing. Neural oscillations were used as windows to investigate plasticity mechanisms; time-frequency analysis was employed when short stimuli were presented, and neural tracking when the stimuli were continuous. Results revealed that even a low degree of sensory perturbation induces plasticity that extends beyond the deprived modality (study 1); altered neural tracking develops following a medium degree perturbation (study 2); a high degree of perturbation has a widespread impact on neural activity (study 3). These results strengthen evidence of the pivotal role of sensory experience revealing multifaced aspects of experience-dependent plasticity. Modeling the degree of perturbation could be a helpful perspective for a deeper understanding of how neural dynamics are affected by different types of deprivation and for shedding light on ranges of flexibility in neural processing with potential clinical implications.

description: We analyse a simple model with just a $Λ$ term present. Differing results are obtained depending on the boundary conditions applied. HH boundary conditions give the factor exp(1/Lambda) but in agreement with Rubakov et al. is badly behaved for negative lambda. Tunneling boundary conditions suggests a large initial lambda. If only a Lorentzian region is considered all boundary conditions suggest a large value of Lambda. This differs from the result of Strominger for such models.

description: The people of Labrador, especially the Inuit, rely on their surrounding resources to sustain themselves and their culture. In particular, the Labrador Inuit depended upon the George River Caribou Herd (GRCH), once one of the largest caribou herds in the world, to provide them with a staple food supply, nourishment, materials, and facilitate the intergenerational sharing of knowledge and important social and cultural norms, all of which are critical to life in Arctic and subarctic environments. This woodland caribou population, however, has declined by 99% over much of it range resulting in a hunting ban, and consequently, a cascade of impacts on the Inuit of northern Labrador. Examining and understanding these impacts is the focus of this thesis. As management of wildlife in North America is to follow the Public Trust Doctrine—to manage wildlife in the public trust—this thesis helps bring the information of Inuit impacts into the discussion to help inform future best practices for more accountable, responsible, and locally responsive wildlife management efforts in the North.

description: We study a toy model of a multiverse consisting of canonically quantized universes that interact with each other on a quantum level based on a field-theoretical formulation of the Wheeler-DeWitt equation. This interaction leads to the appearance of a pre-inflationary phase in the evolution of the individual universes. We analyze scalar perturbations within the model and calculate the influence of the pre-inflationary phase onto the power spectrum of these perturbations. The result is that there is a suppression of power on large scales, which can describe well the Planck 2018 data for the cosmic microwave background anisotropies and could thus indicate a possible solution to the observed quadrupole discrepancy.

Canonical measure and the flatness of a FRW universe

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

description: We consider the claim of Hawking and Page that the canonical measure applied to a FRW universe with a massive scalar field can solve the flatness problem regardless of inflation. By considering a general potential we are able to understand how the ambiguity for $Ω$ found by Page in the $R^2$ theory is present when the potential is bounded from above. We suggests reasons why such potentials are realistic. The ambiguity for the possibility of inflation present in the Gibbons- Hawking- Stewart measure can be resolved by an input from Quantum cosmology. We contrast the resulting measure obtained in this way with those obtained in the more usual approaches to quantum cosmology. The measure agrees with that found from a "classical" signature change.

title: Personal social mobility beliefs and motivation for goals.
Creators: name: Jeon, Byeong Chan
Publisher: name: Memorial University of Newofundland

description: A major life goal for many individuals is to climb the social hierarchy and attain a higher social status than the one they were born into. People’s beliefs regarding the likelihood of moving up or down in social hierarchy (i.e., social mobility) can have a variety of downstream consequences (Day & Fiske, 2019). Across three studies, I examined whether people’s perception of their own social mobility relate to motivation to pursue their goals. In Study 1, I found a positive relationship between personal social mobility beliefs and hope, a motivational state involving goal-oriented thoughts. Next, in order to test whether personal social mobility beliefs can causally increase people’s motivation to pursue their goals, I developed a novel manipulation. The manipulation involved participants completing a test that purportedly assessed their personal likelihood of moving up in social status and provided false feedback regarding these chances (i.e., high vs low personal social mobility). In Study 2, I tested the viability of this manipulation, and in Study 3, I examined whether it would causally affect motivation for general goal pursuit, including hope. Although the manipulation successfully altered personal social mobility beliefs, it did not affect hope. I discuss the implications of these findings for research on mobility beliefs and personal outcomes.

The differences between these interactions in describing properties of nuclear matter are investigated. Various contributions to the total energy are evaluated employing the Hellmann - Feynman theorem. Special attention is paid to the two-nucleon correlation functions derived from these interactions. Differences in the predictions of the various interactions can be traced back to the inclusion of non-local terms.

description: A new class of giant resonances in nuclei, namely double giant resonances, is discussed. They are giant resonances built on top of other giant resonances. Investigation on their properties, together with similar studies on low-lying two-phonon states, should give an answer on how far the harmonic picture of boson-type excitations holds in the finite fermion systems like atomic nuclei. The main attention in this review is paid to double giant dipole resonances (DGDR) which are observed in relativistic heavy ion collisions with very large cross sections. A great experimental and theoretical effort is underway to understand the reaction mechanism which leads to the excitation of these states in nuclei, as well as the better microscopic understanding of their properties. The Coulomb mechanism of the excitation of single and double giant resonances in heavy ion collision at different projectile energies is discussed in details. A contribution of the nuclear excitation to the total cross section of the reaction is also considered. The Coulomb excitation of double resonances is described within both, the second-order perturbation theory approach and in coupled-channels calculation. The properties of single and double resonances are considered within the phenomenologic harmonic vibrator model and microscopic quasiparticle-RPA approach. For the last we use the Quasiparticle-Phonon Model (QPM) the basic ideas and formalism of which are presented. The QPM predictions of the DGDR properties (energy centroids, widths, strength distributions, anharmonicities and excitation cross sections) are compared to predictions of harmonic vibrator model, results of other microscopic calculations and experimental data available.

description: We describe our experience of implementing a news content organization system at Tencent that discovers events from vast streams of breaking news and evolves news story structures in an online fashion. Our real-world system has distinct requirements in contrast to previous studies on topic detection and tracking (TDT) and event timeline or graph generation, in that we 1) need to accurately and quickly extract distinguishable events from massive streams of long text documents that cover diverse topics and contain highly redundant information, and 2) must develop the structures of event stories in an online manner, without repeatedly restructuring previously formed stories, in order to guarantee a consistent user viewing experience. In solving these challenges, we propose Story Forest, a set of online schemes that automatically clusters streaming documents into events, while connecting related events in growing trees to tell evolving stories. We conducted extensive evaluation based on 60 GB of real-world Chinese news data, although our ideas are not language-dependent and can easily be extended to other languages, through detailed pilot user experience studies. The results demonstrate the superior capability of Story Forest to accurately identify events and organize news text into a logical structure that is appealing to human readers, compared to multiple existing algorithm frameworks.

New Algebraic Methods for Calculating the Heat Kernel and Effective Action in Quantum Gravity and Gauge Theories

description: An overview about recent progress in the calculation of the heat kernel and the one-loop effective action in quantum gravity and gauge theories is given. We analyse the general structure of the standard Schwinger-De Witt asymptotic expansion and discuss the applicability of that to the case of strongly curved manifolds and strong background fields. We argue that the low-energy limit in gauge theories and quantum gravity, when formulated in a covariant way, should be related to background fields with covariantly constant curvature, gauge field strength and potential term. It is shown that the condition of the covariant constancy of the background curvatures brings into existence some Lie algebra. The heat kernel operator for the Laplace operator is presented then as an average over the corresponding Lie group with some nontrivial Gaussian measure. Using this representation the heat kernel diagonal is obtained. The result is expressed purely in terms of curvature invariants and is explicitly covariant. Related topics concerning the structure of symmetric spaces and the calculation of the effective action are discussed.

description: We propose a comprehensive investigation into the nature of antimatter as envisioned by RSM. In this framework, matter and antimatter are interpreted as the “crest” and “trough” facets of a single, unified wavefunction. Driven by “meltdown synergy”—a mechanism arising from topology, torsion, and chiral anomalies—the boundaries between these states vanish under certain conditions, leading to infinite adjacency. Our approach combines theoretical rigor (incorporating non-Abelian chiral anomalies, Berry curvature, torsion-induced Chern–Simons transgression, and AdS/CFT analogies) with experimental strategies designed to synthesize topological superfluids and probe exotic phenomena such as fractional charge, chiral spin transport, and even wormhole quantum teleportation. The goal is to revolutionize our understanding of antimatter, topological quantum phases, and the deep interconnections between quantum mechanics and emergent gravitational phenomena. The weak interaction, one of the four fundamental forces of nature, is known for its ability to violate charge-parity (CP) symmetry in certain processes. This violation has profound implications for our understanding of the universe, particularly in relation to the observed asymmetry between matter and antimatter. Furthermore, the weak interaction's ability to break time-reversal symmetry (T) in specific contexts provides a fundamental link to the concept of the arrow of time. In this essay, we will explore how the RSM (Resonant Symmetry Model) framework can reinterpret these phenomena, particularly in the context of chirality, time-reversal, and the unification of matter and antimatter.

A specific “anti-universe” is Ψbranch ant = α C^[Ψbranch univ] the vantage-limited negative amplitude counterpart. This keeps consistency with standard QFT if each branch satisfies CPT collectively...
title: Modulatory effects of physical exercise and transcranial electrical brain stimulation on long-term memory and their associated neural oscillatory activity
Creators: name: Ifram, Fadi
Publisher: name: University of Kent
Year: 2021

description: By providing a standardised design, this thesis aimed to determine the most effective physical exercise (PE) protocol for long-term memory enhancement, whilst directly comparing it to active rest (AR) and passive rest (PR). Concurrently, EEG was recorded during PE to investigate correlations between neural oscillations and enhanced memory performance. Additionally, some studies demonstrated positive effects of transcranial direct current stimulation (tDCS) on declarative memory. Therefore, the effects of PE and tDCS were compared. Further, this was also the first time that acute PE and tDCS were combined into one intervention to investigate whether their combination would elicit further increases in memory modulation. In six studies, 181 participants memorised a series of images and were tested using an old/new recognition task. In studies 1-3, effects of different PE protocols and intensities were compared together and with AR and PR. Study 4 compared the effects of tDCS to moderate- intensity PE and PR. Studies 5 and 6 compared the effects of moderate-intensity PE to the combined intervention after retention intervals of 90 min and 24h. Moderate-intensity PE yielded the greatest enhancements to memory performance compared to PR when tested after 90 min, but not after 24h. While tDCS and PE enhanced memory, the combined intervention impaired memory. Finally, negative correlations between alpha and parietal beta oscillations were correlated to successful memory enhancement, whereas positive correlations between theta, gamma, and frontal beta were correlated with successful memory enhancement. These studies show PE as a potentially successful method of memory enhancement and highlight the complexity of mechanism of action of PE and tDCS in memory enhancement. Together, these findings could have significant implications in the treatment of memory deficiencies. Furthermore, these findings show that tDCS modulates memory similarly to PE, with possible benefits for at-home applications and for people unable to participate in PE.

The intrinsic lifetime of the higher-lying $5d^{10}6s$ $^{2}\text{S}_{1/2}$ state was measurement to be 2.54$\pm$0.10 s, while only a lifetime in the range of 50 - 200 ms could be estimated for the $5d^{9}6s^{2}$ $^{2}\text{D}_{3/2}$ fine-structure level. The storage lifetime of the $\text{Pt}^{-}$ ion beam was measured to be a little over 15 minutes at a ring temperature of 13 K. The present study reports the lifetime of an atomic negative ion in an excited bound state with an electron configuration different from that of the ground state.

description: Adhesives with properties of low-temperature and water-resistance are important in manufacturing. In this work, dopamine hydrochloride (DA), containing catechol groups, was introduced into the polymer by covalent grafting to obtain water-resistant films. Films with low-temperature and water-resistance properties were obtained through layer-by-layer assembly of branched polyethyleneimine (bPEI) and chemically cross-linked hyaluronate (HA)-DA (denoted HA-D). The film surfaces were wetted with moisture generated from low-temperature pretreatment, and the resulting films, named as bPEI/HA-D multilayer films, could adhere strongly by manual application of pressure of about 0.8 MPa. High transmittance (≥78%) was confirmed by ultraviolet–visible absorption spectroscopy, and the adhesion was determined by lap shear tests. Results indicated that the bPEI/HA-D multilayer films had excellent adhesive strengths and were insensitive to temperature, when stored at −20°C (1.08 ± 0.54 MPa), in 100% relative humidity (0.54 ± 0.22 MPa), under ambient conditions (0.99 ± 0.29 MPa), which suggests their potential applications in optical fields and special environments, such as underwater or at low temperature.

description: We study fusion reactions of $^{16}$O with $^{154}$Sm, $^{186}$W and $^{238}$U at sub-barrier energies by a coupled-channels framework. We focus especially on the effects of $β_{6}$ deformation and low-lying vibrational excitations of the target nucleus. It is shown that the inclusion of $β_{6}$ deformation leads to a considerable improvement of the fit to the experimental data for all of these reactions. For the $^{154}$Sm and $^{238}$U targets, the octupole vibration significantly affects the fusion barrier distribution. The effect of $β$ band is negligible in all the three reactions, while the $γ$ band causes a non-negligible effect on the barrier distribution at energies above the main fusion barrier. We compare the optimum values of the deformation parameters obtained by fitting the fusion data with those obtained from inelastic scatterings and the ground state mass calculations. We show that the channel coupling of high multipolarity beyond the quadrupole coupling is dominated by the nuclear coupling and hence higher order Coulomb coupling does not much influence the optimum values of $β_4$ and $β_6$ parameters. We also discuss the effect of two neutron transfer reactions on the fusion of $^{16}$O with $^{238}$U.

Crossed-boson exchange contribution and Bethe-Salpeter equation

description: The contribution to the binding energy of a two-body system due to the crossed two-boson exchange contribution is calculated, using the Bethe-Salpeter equation. This is done for distinguishable, scalar particles interacting via the exchange of scalar massive bosons. The sensitivity of the results to the off-shell behavior of the operator accounting for this contribution is discussed. Large corrections to the Bethe-Salpeter results in the ladder approximation are found. For neutral scalar bosons, the mass obtained for the two-body system is close to what has been calculated with various forms of the instantaneous approximation, including the standard non-relativistic approach. The specific character of this result is demonstrated by a calculation involving charged bosons, which evidences a quite different pattern. Our results explain for some part those obtained by Nieuwenhuis and Tjon on a different basis. Some discrepancy appears with increasing coupling constants, suggesting the existence of sizeable contributions involving more than two-boson exchanges.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

Vanishing Gamow-Teller Transition Rate for A=14 and the Nucleon-Nucleon Interaction in the Medium

description: The problem of the near vanishing of the Gamow-Teller transition ($GT$) in the A=14 system between the lowest $J=0^+~ T=1$ and $J=1^+~ T=0$ states is revisited. The model space is extended from the valence space $(p^{-2})$ to the valence space plus all 2$\hbar ω$ excitations. The question is addressed as to what features of the effective nucleon-nucleon interaction in the medium are required to obtain the vanishing $GT$ strength in this extended space. It turns out that a combination of a realistic strength of the tensor force combined with a spin-orbit interaction which is enhanced as compared to the free interaction yields a vanishing $GT$ strength. Such an interaction can be derived from a microscopic meson exchange potential if the enhancement of the small component of the Dirac spinors for the nucleons is taken into account.

description: A mesoscopic device in the simple tunnel junction or quantum point contact geometry emits microwaves with remarkable quantum properties, when subjected to a sinusoidal drive in the GHz range. In particular, single and two-photon squeezing as well as entanglement in the frequency domain have been reported. By revising the photo-assisted noise analysis developed in the framework of electron quantum optics, we present a detailed comparison between the cosine drive case and other experimentally relavent periodic voltages such as rectangular and Lorentzian pulses. We show that the latter drive is the best candidate in order to enhance quantum features and purity of the outgoing single and two-photon states, a noteworthy result in a quantum information perspective.

description: A sputter ion source with a solid graphite target has been used to produce dianions with a focus on carbon cluster dianions, $\text{C}_{n}^{2-}$, with $n=7-24$. Singly and doubly charged anions from the source were accelerated together to kinetic energies of 10 keV per atomic unit of charge and injected into one of the cryogenic (13 K) ion-beam storage rings of the Double ElectroStatic Ion Ring Experiment facility at Stockholm University. Spontaneous decay of internally hot $\text{C}_{n}^{2-}$ dianions injected into the ring yielded $\text{C}^{-}$ anions with kinetic energies of 20 keV, which were counted with a microchannel plate detector. Mass spectra produced by scanning the magnetic field of a $90^{\circ}$ analyzing magnet on the ion injection line reflect the production of internally hot $\text{C}_{7}^{2-}-\text{C}_{24}^{2-}$ dianions with lifetimes in the range of tens of microseconds to milliseconds. In spite of the high sensitivity of this method, no conclusive evidence of $\text{C}_{6}^{2-}$ was found while there was a clear $\text{C}_{7}^{2-}$ signal with the expect isotopic distribution. An upper limit is deduced for a $\text{C}_{6}^{2-}$ signal that is two orders-of-magnitue smaller than that for $\text{C}_{7}^{2-}$. In addition, $\text{C}_{n}\text{O}^{2-}$ and $\text{CsCu}^{2-}$ dianions were detected.
