Lower and Upper Conditioning in Quantum Bayesian Theory

description: Updating a probability distribution in the light of new evidence is a very basic operation in Bayesian probability theory. It is also known as state revision or simply as conditioning. This paper recalls how locally updating a joint state can equivalently be described via inference using the channel extracted from the state (via disintegration). This paper also investigates the quantum analogues of conditioning, and in particular the analogues of this equivalence between updating a joint state and inference. The main finding is that in order to obtain a similar equivalence, we have to distinguish two forms of quantum conditioning, which we call lower and upper conditioning. They are known from the literature, but the common framework in which we describe them and the equivalence result are new.

description: The indirect RKKY interaction in a layered metal with nearly nested (almost squared) Fermi surface is evaluated analytically. The final expressions are obtained in closed form as a combination of Bessel functions. We show that the expected ``2k_F'' oscillations occur as the far asymptote of our expressions, where a value of the effective Fermi momentum k_F depends on the direction in r-space. We demonstrate the existence of the intermediate asymptote of the interaction which is of the sign-reversal antiferromagnetic type. This part of RKKY interaction is the only term surviving in the limit of exact nesting. A good accordance of our analytical formulas with numerical findings is found until the interatomic distances.

Cannabis Metabolomics: Comparison of Cannabis Products and Effect of Vaporization

description: Cannabis is widely consumed medically and recreationally due to the presence of cannabinoids, but the phytochemical complexity of different varieties and preparations is a major knowledge gap. This thesis investigated the phytochemicals present in thirteen different cannabis strains using untargeted and targeted phytochemical analysis to determine “strain” differences in cannabis tinctures and oils. In addition, the phytochemical differences between different oil products, namely oils extracted by ethanol and CO2 supercritical fluid, were also determined to evaluate different processing methods. It was found that inter-strain variability was more significant than the preparation methods due to the strain-specific presence of major cannabinoids, specifically THCA and CBDA. Furthermore, a processing step like drying removed phytochemicals contributing to strain differences, most notably terpenes. The results suggested that consumers can expect different strains and products to have different chemical profiles, as CO2 oils were found to be more chemically consistent across products than tinctures. Cannabis can be consumed in many different ways, and one popular mode of delivery is vaporization. Vaporization extracts active principles of cannabis with heated gas and could lead to a different phytochemical profile compared to the original flower counterpart. Consequently, the product label based on the raw material may not be representative of what is phytochemically available during consumption. The results of this study showed a reduction in available chemicals after vaporizing flower and oils, and little new chemical formation through this process. Decarboxylated cannabinoids were the most significant contributors to differences between pre and post-vaporized samples, and different phytochemistry composition was observed after vaporization. The results also demonstrated that vaporization reduces inter-strain and inter-product chemical diversity, but the content of the vapor can still be affected by the strain used. Furthermore, it showed that vaporization could extract phytochemicals differently from oils than flower material. This thesis provides a new understanding of phytochemical differences, extraction and vaporization processes of cannabis, and provides novel insights into cannabis for producers and consumers. Understanding the differences in chemical content of different types of concentrates can better inform producers and consumers about the products they make, sell and use. In addition, this thesis supports the use of vaporization as a harm reduction method for the consumption of cannabis, and increases understanding of cannabis vaporization. The information from this thesis contributes novel insights into cannabis research and provides a foundation for further studies.

description: Relativistic impulse approximation (RIA) has been widely used in atomic, condensed matter, nuclear, and elementary particle physics. In former treatments of RIA formulation, differential cross sections for Compton scattering processes were factorized into atomic Compton profiles by performing further simplified approximations in the integration. In this study, we develop an ``exact'' numerical method without using any further simplified approximations or factorization treatments. The validity of the approximations and factorizations used in former RIA treatments can be tested using our approach. Calculations for C, Cu, Ge, and Xe atomic systems are carried out using Dirac-Fock wavefunctions, and comparisons between the proposed approach and former treatments of RIA are performed and discussed in detail. Numerical results indicate that these simplified approximations work reasonably in the Compton peak region, and our results have little difference with the best of the former RIA treatments in the entire energy region. While in regions far from the Compton peak, the RIA results become inaccurate, even when our ``exact'' numerical treatment is used.

description: A nivel mundial hay preocupación por la intensificación del calentamiento global, al cual, entre muchos otros factores, contribuye las emisiones de Gases Efecto Invernadero (GEI), conocido como huella de carbono. Específicamente las actividades agrícolas aportan aproximadamente un 13,5% a las emisiones mundiales de GEI. En Colombia, la economía es fuertemente movida por el sector agrícola. Si bien, algunos investigadores del país han adelantado estudios sobr1e estimación y/o mitigación de huella de carbono en cultivos de productos específicos (arroz, caña de azúcar, flores, etc.), no se ha experimentado hasta el momento el uso de tecnologías de Inteligencia Artificial (IA) para apoyar los procesos que conlleva dicha estimación y/o mitigación. En este proyecto se aplicará la rama de la IA conocida como Planificación Automática (AP, por sus siglas en inglés) para crear planes de mitigación de huella de carbono generada por actividades agrícolas en Colombia. Para esto, es necesario parametrizar las actividades emisoras de GEI y las acciones asociadas a estrategias de mitigación de tal manera que se convierta en un sistema referente para cultivos en Colombia, agnóstico al producto agrícola.

description: Within the light front framework, we calculate the form factors for $B\toγ$ transitions directly in the entire physical range of momentum transfer. Using these form factors, we study the radiative decays of $B\to lν_lγ$ and $B_{s(d)}\toν\barνγ$. We show that the decay rates of $B\to lν_lγ(l=e,μ)$ and $B\toν\barνγ$ are larger than that of the corresponding purely leptonic modes. Explicitly, in the standard model, we find that the branching ratios of $B\to μν_μγ$ and $B_s\toν\barνγ$ are $3.7\times 10^{-6}$ and $5.0\times 10^{-8}$, in contrast with $3\times 10^{-7}$ and 0 for $B\toμν_μ$ and $B\toν\barν$, respectively.

A Critical Appraisal of the Regulatory Regime of Islamic Banking in Ethiopia
Creators: name: Oumer, Kamil Abdu
Publisher: name: Manara - Qatar Research Repository
Year: 2025
Subjects: classificationCode: 50
subject: Philosophy and religious studies

description: The National Bank of Ethiopia Directive to License and Authorise Interest Free Banking Business, Directive Number SBB/72/2019, allowed a full-fledged interest free banking business for the first time in the history of the country. The Directive prescribed that “all regulatory and supervisory requirements except National Bank’s directive on interest rate” shall be applied to Interest free banks mutatis mutandis. Accordingly, all National bank directives issued to regulate “conventional” banks shall be applied to Islamic banks subject to appropriate modification. In this study, the regulatory directives of the National Bank of Ethiopia were critically examined in the light of the fundamental principles of Islamic finance and plausible recommendations are forwarded for the designing of regulatory system for Islamic banks in the Ethiopian secular set up. The research primary depends on qualitative data. It, however, benefited from quantitative data to substantiate its arguments. Data was collected from the websites of the National Bank of Ethiopia and commercial banks in the country. The collected data were analysed in line with the principles of Islamic banking and the experiences of Turkey. The finding shows that the current regulatory regime is hardly sufficient to help build sustainable Islamic banking in the country.

description: Using the method of symbolic dynamics, we show that a large class of classical chaotic maps exhibit exponential hypersensitivity to perturbation, i.e., a rapid increase with time of the information needed to describe the perturbed time evolution of the Liouville density, the information attaining values that are exponentially larger than the entropy increase that results from averaging over the perturbation. The exponential rate of growth of the ratio of information to entropy is given by the Kolmogorov-Sinai entropy of the map. These findings generalize and extend results obtained for the baker's map [R. Schack and C. M. Caves, Phys. Rev. Lett. 69, 3413 (1992)].

description: The goal of this study is to assess the potential advantages of utilising methotrexate (MTH), and mangiferin (MFR), in nanoparticulate configuration which is transethosomes (TRS), which could result in increased stability and solubility, as well as improved infiltration into the arthritic tissues under investigation. The synthesised MTH-MFR-TRS demonstrated a particle size of 151.7 nm and a PDI of 0.1199. Additionally, the zeta potential was observed to be favourable at −30.43 mV. Supplementary evaluations were performed, comprising transmission electron microscopy (TEM), confocal microscopy and skin permeation analysis. The CLSM study revealed that the MTH-MFR-TRS gel formulation demonstrated enhanced permeation of MTH and MFR through the skin layers in comparison with MTH-MFR suspension gel. The results of the in vivo investigation indicate that the MTH-MFR-TRS gel displays favourable anti-arthritic characteristics compared to the diclofenac standard gel. The aforementioned phenomenon was evidenced by means of histopathological investigations and radiographic scrutiny. The study at hand has validated the utility of TRS vesicles as a carrier for the transdermal administration of MTH and MFR, thereby offering a promising therapeutic approach for the management of rheumatoid arthritis.
Electron Correlations in Partially Filled Lowest and Excited Landau Levels
Creators: name: Wojs, Arkadiusz
Publisher: name: arXiv
Year: 2000
Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)
subject: FOS: Physical sciences

description: The electron correlations near the half-filling of the lowest and excited Landau levels (LL's) are studied using numerical diagonalization. It is shown that in the low lying states electrons avoid pair states with relative angular momenta ${\cal R}$ corresponding to positive anharmonicity of the interaction pseudopotential $V({\cal R})$. In the lowest LL, the super-harmonic behavior of $V({\cal R})$ causes Laughlin correlations (avoiding pairs with ${\cal R}=1$) and the Laughlin-Jain series of incompressible ground states. In the first excited LL, $V({\cal R})$ is harmonic at short range and a different series of incompressible states results. Similar correlations occur in the paired Moore-Read $ν={5\over2}$ state and in the $ν={7\over3}$ and ${8\over3}$ states, all having small total parentage from ${\cal R}=1$ and 3 and large parentage from ${\cal R}=5$. The $ν={7\over3}$ and ${8\over3}$ states are different from Laughlin $ν={1\over3}$ and ${2\over3}$ states and, in finite systems, occur at a different LL degeneracy (flux). The series of Laughlin correlated states of electron pairs at $ν=2+2/(q_2+2)={8\over3}$, ${5\over2}$, ${12\over5}$, and ${7\over3}$ is proposed, although only in the $ν={5\over2}$ state pairing has been confirmed numerically. In the second excited LL, $V({\cal R})$ is sub-harmonic at short range and (near the half-filling) the electrons group into spatially separated larger $ν=1$ droplets to minimize the number of strongly repulsive pair states at ${\cal R}=3$ and 5.

Tunneling with the Lorentz Force and the Friction

description: We present a semiclassical study of a transport process, the tunneling, in the presence of a magnetic field and a dissipative environment. We have found that the problem can be mapped onto an effective one-dimensional one, and the tunneling rate is strongly affected by the magnetic field, such as a complete suppression by a large parallel magnetic field, an example of the dynamical localization. In such case a small perpendicular component of the field, or the dissipation, can enhance the tunneling rate. In the small parallel field and finite temperatures the tunneling rate is finite. Explicit expressions will be presented in those cases. If viewing the tunneling in the presence of a magnetic field as a dissipative tunneling process, by varying the magnetic field and the potential one can obtain the dissipative spectral function between the subohmic $s =0$ and the superohmic $s = \infty$. In combination with a real dissipative spectral function, the effect of the magnetic field can map the spectral function from $s $ to $2-s$, with $s>2$ mapping to $ s = 0$, revealing a dual symmetry between the friction and the Lorentz force. Two cases relevant to experiments, the edge state tunneling in a Hall bar and the tunneling near the dynamical localization will be discussed in detail.

description: This paper presents an exploratory study of the frequency response and linear stability of molten salt reactors (MSRs) using the continuous stirred-tank reactor (CSTR) and the plug flow reactor (PFR) models. Linear stability analysis is crucial to understanding the dynamic behavior of nuclear reactors, especially MSRs, which employ circulating liquid salt as both fuel and coolant. Unlike conventional reactors, the dynamic behavior of MSRs is influenced by the tight coupling between flow dynamics and neutronics, as well as the strong interzonal interactions within the core. This paper contrasts the two models, emphasizing the PFR’s ability to capture recirculation resonances and other kinetic phenomena neglected by the CSTR approximation. The developed theoretical models are applied to the Molten Salt Reactor Experiment (MSRE), and their predictions are compared with experimental data. This study also explores the sensitivity of reactor frequency response and stability to amplitude changes in fuel and moderator reactivity feedback mechanisms and the fuel flow rate. The findings demonstrate that both models provide an analytically solvable framework for MSR stability analysis. Despite the more involved theoretical basis of the PFR model, the CSTR model results are shown to correspond more closely to the reference MSRE data.
An Improved Model of Direct Gauge Mediation

Publisher: name: arXiv
Year: 1998
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We present a new, improved model of gauge mediation of dynamical SUSY Breaking: the model does not have gauge messengers or $\sim 10$ TeV scalars charged under the Standard Model (SM), thus avoiding the problem of negative (mass)$^2$ for supersymmetric SM (SSM) scalars faced by some earlier models. The gauge mediation is direct, i.e., the messengers which communicate SUSY breaking to the SSM fields carry quantum numbers of the gauge group which breaks SUSY. These messenger fields couple to a modulus field. The model has a very simple particle content: the modulus and the messengers are the only chiral superfields (other than the SSM fields) in the model. The inverted hierarchy mechanism is used to generate a local SUSY breaking minimum for the modulus field in a perturbative regime thus making the model calculable.

description: Purpose: This paper reports findings from phase two of a multiphase cross-cultural research programme exploring the professional practice of a group of Vietnam’s first university-qualified speech-language pathologists. Method: Employing qualitative research methodology, this study involved a series of workshops with seven Vietnamese speech-language pathologists in which visual research methods were used to explore the evolution of their work, the challenges they faced, and opportunities to progress their professional practice. Thematic analysis employing a mixed deductive-inductive approach was used to analyse the textual data. Result: Heightened awareness of the speech-language pathology profession in Vietnam, movement into specialisation and expansion of services into the private sector were described. Dual professional roles, limited access to culturally-relevant resources to support practice and lack of experience in advocating for services posed challenges, whilst community education, the conduct of research, and the training of others in speech-language pathology were progressing the profession. Conclusion: The professional practice of a group of Vietnam’s first speech-language pathologists is growing. Opportunities to advance their practice will best be informed by knowledge that reflects local context and culture and includes the experiences and preferences of persons living with communication and swallowing disabilities in Vietnam and their families.
First-principles quantum transport simulation of CuPc on Au(111) and Ag(111)

description: We investigate equilibrium and transport properties of a copper phthalocyanine (CuPc) molecule adsorbed on Au(111) and Ag(111) surfaces. The CuPc molecule has essentially three localized orbitals close to the Fermi energy resulting in strong local Coulomb repulsion not accounted for properly in density functional calculations. Hence, they require a proper many-body treatment within, e.g., the Anderson impurity model (AIM). The occupancy of these orbitals varies with the substrate on which CuPc is adsorbed. Starting from density functional theory calculations, we determine the parameters for the AIM embedded in a noninteracting environment that describes the residual orbitals of the entire system. While correlation effects in CuPc on Au(111) are already properly described by a single orbital AIM, for CuPc on Ag(111) the three orbital AIM problem can be simplified into a two orbital problem coupled to the localized spin of the third orbital. This results in a Kondo effect with a mixed character, displaying a symmetry between SU(2) and SU(4). The computed Kondo temperature is in good agreement with experimental values. To solve the impurity problem we use the recently developed fork tensor product state solver. To obtain transport properties, a scanning tunneling microscope (STM) tip is added to the CuPc molecule absorbed on the surface. We find that the transmission depends on the detailed position of the STM tip above the CuPc molecule in good agreement with differential conductance measurements.

description: We investigate the instability of the unstable circular orbit of a charged null particle to test the strong cosmic censorship conjecture in Nariai-type near-extremal Reissner--Nordström--de Sitter black holes. The instability is estimated as the Lyapunov exponent and found to depend on the mass and charge of the black hole. Then, we explicitly show that charged null particles in unstable circular orbits correspond to the charged massless scalar field in the eikonal limit. This provides a compact relationship representing the quasinormal frequency in terms of the characteristics of unstable circular orbits in near Nariai-type extremal conditions. According to this relationship, the strong cosmic censorship conjecture is valid.

description: For two-dimensional topological insulators, the integer and intrinsic (without external magnetic field) quantum Hall effect is described by the gauge anomalous (2+1)-dimensional [2+1d] Chern-Simons (CS) response for the background gauge potential of the electromagnetic U(1) field. The Hall conductance is given by the quantized prefactor of the CS term, which is a momentum-space topological invariant. Here, we show that three-dimensional crystalline topological insulators with no other symmetries are described by a topological (3+1)-dimensional [3+1d] mixed CS term. In addition to the electromagnetic U(1) gauge field, this term contains elasticity tetrad fields $E^{\ a}_μ({\bf r},t) = \partial_μX^a(\mathbf{r},t)$ which are gradients of crystalline U(1) phase fields $X^a(\mathbf{r},t)$ and describe the deformations of the crystal. For a crystal in three spatial dimensions $a=1,2,3$ and the mixed axial-gravitational response contains three parameters protected by crystalline symmetries: the weak momentum-space topological invariants. The response of the Hall conductance to the deformations of the crystal is quantized in terms of these invariants. In the presence of dislocations, the anomalous 3+1d CS term describes the Callan-Harvey anomaly inflow mechanism. The response can be extended to all odd spatial dimensions. The elasticity tetrads, being the gradients of the lattice U(1) fields, have canonical dimension of inverse length. Similarly, if such tetrad fields enter general relativity, the metric becomes dimensionful, but the physical parameters, such as Newton's constant, the cosmological constant, and masses of particles, become dimensionless.

description: We theoretically investigate the super- and sub-radiance from the resonant dipole-dipole interactions (RDDI) in a confined two-dimensional (2D) reservoir. The distinctive feature of 2D RDDI shows qualitatively and quantitatively different long-range behavior from RDDI in free space. We investigate the superradiant properties of the singly-excited symmetric state under this 2D RDDI. This state also allows subradiant decays in much longer distances than the transition wavelength, showing long-range atom-atom correlations. We further study the dynamics of the subradiant states which can be accessed by imprinting spatially dependent phases on the atomic arrays. Our results demonstrate rich opportunities in engineering light-matter interactions in a confined 2D reservoir, and hold promise in applications of quantum light storage and single-excitation state manipulations.

description: We show that model states of fractional quantum Hall fluids at all experimentally detected plateau can be uniquely determined by imposing translational invariance with a particular scheme of Hilbert space truncation motivated from physical local measurements. The scheme allows us to identify filling factors, topological shifts and pairing/clustering of topological quantum fluids unambiguously in a universal way without resorting to microscopic Hamiltonians. This prompts us to propose the notion of emergent commensurability as a fundamental property for at least most of the known FQH states, which allows us to predict if a particular FQH state conforming to a set of paradigms can be realised \emph{in principle}. We also discuss the implications of certain missing states proposed from other phenomenological approaches, and suggest that the physics of fractional quantum Hall physics could fundamentally arise from the algebra of the Hilbert space in a single Landau level.

description: Abstract

 Hepatitis B was first exposed in 1965 in the serum of Australians, the epidemiologists known as Australian antigen, the ampoule particle was discovered in 1970 and in 1980s the sequencing of the viral genome and first testing of the hepatitis B vaccine. Globally Hepatitis B virus infection is careful as a major public health problem and around 30% of global people serological tests show positivity of either current or past infection, Christian T, Henry L Y Chan and Anna Lok (2014). Studies show that about 40% of men and 15% of women who with acquired hepatitis B virus infection during prenatal period die of either liver cirrhosis or hepatocellular carcinoma,

description: As urbanization increases, municipalities across the world have become aware of the negative impacts of road-based transportation, which include traffic congestion and air pollution. As a result, several cities have introduced tolling schemes to discourage vehicles from entering the inner city. However, little research has been done to examine the impact of tolling schemes on the routing of commercial fleets, especially on the resulting costs and emissions. In this study, we investigate a vehicle routing problem considering different congestion charge schemes for several city types. We design comprehensive computational experiments to investigate whether different types of tolling schemes work in the way municipalities expect and what factors affect the performance of the congestion charge schemes. We compare the impact on a company's total costs, fuel usage (which drives emissions), and delivery tour plans. Our experimental results demonstrate that some congestion pricing schemes may even increase the emissions in the city center, and higher congestion charges may not necessarily lead to lower emissions.

description: We discover a qualitatively new behavior for systems where the load transfer has limiting stress amplification as in real fiber composites. We find that the disorder is a relevant field leading to tri--criticality, separating a first-order regime where rupture occurs without significant precursors from a second-order regime where the macroscopic elastic coefficient exhibit power law behavior. Our results are based on analytical analysis of fiber bundle models and numerical simulations of a two-dimensional tensorial spring-block system in which stick-slip motion and fracture compete.

Higher Spin ANEC and the Space of CFTs

description: We study the positivity properties of the leading Regge trajectory in higher-dimensional, unitary, conformal field theories (CFTs). These conditions correspond to higher spin generalizations of the averaged null energy condition (ANEC). By studying higher spin ANEC, we will derive new bounds on the dimensions of charged, spinning operators and prove that if the Hofman-Maldacena bounds are saturated, then the theory has a higher spin symmetry. We also derive new, general bounds on CFTs, with an emphasis on theories whose spectrum is close to that of a generalized free field theory. As an example, we consider the Ising CFT and show how the OPE structure of the leading Regge trajectory is constrained by causality. Finally, we use the analytic bootstrap to perform additional checks, in a large class of CFTs, that higher spin ANEC is obeyed at large and finite spin. In the process, we calculate corrections to large spin OPE coefficients to one-loop and higher in holographic CFTs.

Sum-rule for large-$N_c$ QCD and application to heavy quarkonia

Publisher: name: arXiv
Year: 1997
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We introduce a new sum-rule for large-$N_c$ QCD which relates the density of heavy quarkonium states, the state-averaged square of the wavefunction at the origin, and the heavy quark current-current correlator. Focusing on the region of energy just above perturbative threshold, we calculate the correlator by incorporating arbitrarily high orders in the QCD coupling $α_s$. We use the sum-rule to determine the bottomonium potential using experimentally measured s-wave leptonic widths and compare the result with the potential obtained by direct calculation from the measured s-wave spectrum. We discuss the utility of the sum-rule method for accurate determination of the confining potential.

Observable tests of self-interacting dark matter in galaxy clusters: BCG wobbles in a constant density core

description: Models of Cold Dark Matter predict that the distribution of dark matter in galaxy clusters should be cuspy, centrally concentrated. Constant density cores would be strong evidence for beyond-CDM physics, such as Self-Interacting Dark Matter (SIDM). An observable consequence would be oscillations of the Brightest Cluster Galaxy (BCG) in otherwise relaxed galaxy clusters. Offset BCGs have indeed been observed - but only interpreted via a simplified, analytic model of oscillations. We compare these observations to the BAHAMAS-SIDM suite of cosmological simulations, which include SIDM and a fully hydrodynamical treatment of star formation and feedback. We predict that the median offset of BCGs increases with the SIDM cross-section, cluster mass and the amount of stellar mass within 10kpc, while CDM exhibits no trend in mass. Interpolating between the simulated cross-sections, we find that the observations (of 10 clusters) is consistent with CDM at the ~1.5$σ$ level, and prefer cross-section $σ$/m < 0.12(0.39)cm$^2$/g at 68% (95%) confidence level. This is on the verge of ruling out velocity-independent dark matter self-interactions as the solution to discrepancies between the predicted and observed behaviour of dwarf galaxies, and will be improved by larger surveys by Euclid or SuperBIT.
