description: A nonparametric Bayesian approach is developed to determine quantum potentials from empirical data for quantum systems at finite temperature. The approach combines the likelihood model of quantum mechanics with a priori information over potentials implemented in form of stochastic processes. Its specific advantages are the possibilities to deal with heterogeneous data and to express a priori information explicitly, i.e., directly in terms of the potential of interest. A numerical solution in maximum a posteriori approximation was feasible for one--dimensional problems. Using correct a priori information turned out to be essential.

Quantitative Predictions for $B$ semileptonic decays into $D,D^*$ and the orbitally excited $D^{**}$ in quark models à la Bakamjian-Thomas

description: Once chosen the dynamics in one frame, the rest frame in this paper, the Bakamjian and Thomas method allows to define relativistic quark models in any frame. These models have been shown to provide, in the infinite quark mass limit, fully covariant current form factors as matrix elements of the quark current operator. In this paper we use the rest frame dynamics fitted from the meson spectrum by various authors, already shown to provide a reasonable value for $ρ^2$. From the general formulae for the scaling invariant form factors $ξ^{(n)}(w)$, $τ_{1/2}^{(n)}(w)$ and $τ_{3/2}^{(n)}(w)$, we predict quantitavely the $B$ semileptonic branching ratios to the ground state and orbitally excited charmed mesons $D, D^\ast$ and $D^{\ast\ast}$. We check Bjorken's sum rule and discuss the respective contributions to it. We find $ξ(w)\simeq (2/(1+w)) ^2$, resulting from the fact that the ground state wave function is Coulomb-like. We also find $τ_{3/2}\simeq 0.5 (2/(1+w))^3$ and $τ_{1/2}(w)\ll τ_{3/2}(w)$. Very small branching ratios into $j=1/2$ orbitally excited $D$'s results. The overall agreement with experiment is rather good within the present accuracy which is poor for the orbitally excited charmed mesons. We predict a ratio $Br(B\to D^\ast_2 l ν)/Br(B\to D_1 l ν)=1.55\pm 0.15$ as a mere consequence of the heavy quark symmetry. If some faint experimental indications that $Br(B\to D_1 l ν)\simeq Br(B\to D^\ast_2 l ν)$ were confirmed, it would indicate a sizeable $O(1/m_c)$ correction.

description: The Advanced Space-based Solar Observatory (ASO-S) mission aims to explore two most spectacular eruptions in the Sun: solar flares and coronal mass ejections (CMEs), and their magnetism. For the studies of CMEs, the payload Lyman-alpha Solar Telescope (LST) has been proposed. It includes a traditional white-light coronagraph and a Lyman-alpha coronagraph which opens a new window to CME observations. Polarization measurements taken by white-light coronagraphs are crucial to derive fundamental physical parameters of CMEs. To make such measurements, there are two options of Stokes polarimeter which have been used by existing white-light coronagraphs for space missions. One uses a single or triple linear polarizers, the other involves both a half-wave plate and a linear polarizer. We find that the former option subjects to less uncertainty in the derived Stokes vector propagated from detector noise. The latter option involves two plates which are prone to internal reflections and may have a reduced transmission factor. Therefore, the former option is adopted as our Stokes polarimeter scheme for LST. Based on the parameters of the intended linear polarizer(s) colorPol provided by CODIXX and the half-wave plate 2-APW-L2-012C by Altechna, it is further shown that the imperfect maximum transmittance of the polarizer significantly increases the variance amplification of Stokes vector by at least about 50% when compared with the ideal case. The relative errors of Stokes vector caused by the imperfection of colorPol polarizer and the uncertainty due to the polarizer assembling in the telescope are estimated to be about 5%. Among the considered parameters, we find that the dominant error comes from the uncertainty in the maximum transmittance of the polarizer.

description: Neurotensin (NTS) is a 13-amino acid neuropeptide with neuroendocrine and vasoactive functions that is widely expressed in the central nervous system and gastrointestinal tract. NTS is sensed by a multiple cell surface proteins including two G protein-coupling receptors (GPCRs): NTS receptors 1 and 2 (NTSR1 and NTSR2). Crystal structures of NTSR1 have successfully elucidated agonist binding within the orthosteric pocket of receptor but have not revealed the full activation state of the receptor. Recent studies have attempted to address this challenge by improving NTSR1 crystal formation via thermostable mutants; unfortunately, these mutations exhibit functional defects in the G protein coupling of NTSR1. Here, we have used molecular dynamics simulations to gain greater insights into how the amino acid substitutions used in these thermostable mutants (E166A, L310A and F358A) impact receptor activation. Our simulations indicate that wild-type NTSR1 in complex with NTS8-13 shows more active-like features including a 17.7 Å shift in TM6, reflecting a network of polar and aromatic interactions orchestrating agonist-induced receptor conformational changes. We also provide evidence indicating that F358 is a precursor to the rotamer change observed in W321, and our collective analysis also suggests that mutations E166A and F358A are less impactful to G protein coupling than L310A. Furthermore, we believe that our findings can be used to design future NTSR1 mutants that do not interfere with agonist-induced conformational changes and downstream G protein coupling and thus produce structures that will allow visualization of the fully activated receptor conformation.

description: We develop an instanton approach to the non-equilibrium dynamics in one-dimensional random environments. The long time behavior is controlled by rare fluctuations of the disorder potential and, accordingly, by the tail of the distribution function for the time a particle needs to propagate along the system (the delay time). The proposed method allows us to find the tail of the delay time distribution function and delay time moments, providing thus an exact description of the long-time dynamics. We analyze arbitrary environments covering different types of glassy dynamics: dynamics in a short-range random field, creep, and Sinai's motion.

description: The agreement of the nuclear equation of state (EoS) deduced from the GW170817 based tidal deformability with the one obtained from empirical data on microscopic nuclei is examined. It is found that suitably chosen experimental data on isoscalar and isovector modes of nuclear excitations together with the observed maximum neutron star mass constrain the EoS which displays a very good congruence with the GW170817 inspired one. The giant resonances in nuclei are found to be instrumental in limiting the tidal deformability parameter and the radius of neutron star in somewhat narrower bounds. At the 1$σ$ level, the values of the canonical tidal deformability $Λ_{1.4}$ and the neutron star radius $R_{1.4}$ come out to be $267\pm144$ and $11.6\pm1.0$ km, respectively.

Locating Objects with Signal Times Amongst Shadows and Black Holes in Two-Dimensional Models

description: Calling mammals, ships, and many other objects have been commonly located during the last century with two-dimensional (2D) models from measurements of signal time even when the objects are not on the 2D surface. The overwhelmingly common method for locating signals with 2D models takes signal speed as constant. Distance is computed by multiplying this speed by signal time. For monostatic, bistatic, and Time Differences of Arrival (TDOA) measurements, the distances constrain locations to circles, ellipses, and hyperbolas respectively, whose intersections yield location. However, the speed needed to obtain correct locations depends on the horizontal separation between object and instrument. In fact, if their horizontal separation is zero the speed needed for correct location must also be zero. In light of this singularity, methods are derived for generating extremely reliable confidence intervals for location and identifying regions of the 2D model where a 3D model is needed. Because speeds needed for correct location are spatially in-homogeneous in the extreme, isosigmachrons and isodiachrons emerge as natural geometries for interpreting location instead of ellipses and hyperbolas. These issues are caused by choice of coordinates, and the same phenomena occur in general relativity regarding the speed of light and black holes.

Resolution-induced anisotropy in LES

description: Large eddy simulation (LES) of turbulence in complex geometries and domains is often conducted with high aspect ratio resolution cells of varying shapes and orientations. The effects of such anisotropic resolution are often simplified or neglected in subgrid model formulation. Here, we examine resolution induced anisotropy and demonstrate that, even for isotropic turbulence, anisotropic resolution induces mild resolved Reynolds stress anisotropy and significant anisotropy in second-order resolved velocity gradient statistics. In large eddy simulations of homogeneous isotropic turbulence with anisotropic resolution, it is shown that commonly used subgrid models, including those that consider resolution anisotropy in their formulation, perform poorly. The one exception is the anisotropic minimum dissipation model proposed by Rozema et al. (Phys. of Fluids 27, 085107, 2015). A simple new model is presented here that is formulated with an anisotropic eddy diffusivity that depends explicitly on the anisotropy of the resolution. It also performs well, and is remarkable because unlike other LES subgrid models, the eddy diffusivity only depends on statistical characteristics of the turbulence (in this case the dissipation rate), not on fluctuating quantities. In other subgrid modeling formulations, such as the dynamic procedure, limiting flow dependence to statistical quantities in this way could have advantages.

description: The Standard Model prediction for muon-electron scattering beyond leading order requires the inclusion of QCD contributions which cannot be computed perturbatively. At next-to- and next-to-next-to-leading order, they arise from one- and two-loop diagrams with hadronic vacuum polarization insertions in the photon propagator. We present their evaluation using the dispersive approach with hadronic $e^+e^-$ annihilation data and estimate their uncertainty. We find that these corrections are crucial for the analysis of future high-precision muon-electron scattering data, like those of the recently proposed MUonE experiment at CERN.

description: The electric dipole moment (EDM) of an atom could arise also from $P$-odd and $T$-odd electron-nucleon couplings. In this work we investigate a general class of dimension-$6$ electron-nucleon ($e$-$N$) nonminimal interactions mediated by Lorentz-violating (LV) tensors of rank ranging from $1$ to $4$. The possible couplings are listed as well as their behavior under $C$, $P$ and $T$, allowing us to select the couplings compatible with EDM physics. The unsuppressed contributions of these couplings to the atom's Hamiltonian can be read as EDM-equivalent. The LV coefficients' magnitudes are limited using EDM experimental data to the level of $3.2\times 10^{-13} \text{(GeV)}^{-2}$ or $1.6\times10^{-15} \text{(GeV)}^{-2}$.

description: Minor morphological differences between the Atlantic and Mediterranean populations of Pomatoschistus pictus (Malm, 1865) resulted in the description of two subspecies of this species by Miller (1973): Pomatoschistus pictus pictus and P. p. adriaticus. However, the similarity of morphometric and meristic characteristics led to an ambiguity about their status. Despite high morphological similarities between the Atlantic and Mediterranean populations, we found that the population in the Sea of Marmara (Erdek) differs from the Atlantic population in terms of the frequency of papillae in the occipital rows g and h, the position of the suborbital row b and the colouration of the second dorsal fin. Examination of the DNA sequence of the COI gene showed that the K2P genetic distance between the population in the Atlantic and the Sea of Marmara (Erdek) was 7.9%, while the minimum interspecific distance between any other Pomatoschistus species was determined as 4.3%. We concluded based on the combined genetic and morphological results that the population in the Sea of Marmara represents a species that is distinct from the Atlantic species P. pictus. It is likely that it belongs to Pomatoschistus pictus adriaticus described in the Adriatic Sea and should be given a species rank.

We use events collected by the CDF experiment from $p\bar p$ collisions at \sqrt s=1.8 TeV at the Tevatron collider. We measure a top quark mass of 167.4 \pm 10.3(stat) \pm 4.8(syst) GeV/c^2 from a sample of eight events. We combine this result with previous CDF measurements in other decay channels to obtain a mass value of 176.0 \pm 6.5 GeV/c^2.

description: The first-passage problem of the Ornstein-Uhlenbeck process to a boundary is a long-standing problem with no known closed-form solution except in specific cases. Taking this as a starting-point, and extending to a general mean-reverting process, we investigate the long- and short-time asymptotics using a combination of Hopf-Cole and Laplace transform techniques. As a result we are able to give a single formula that is correct in both limits, as well as being exact in certain special cases. We demonstrate the results using a variety of other models.

description: We construct the low-energy effective lagrangian for a light gravitino coupled to the minimal supersymmetric standard model under the assumption that supersymmetry breaking is communicated to the observable sector dominantly through soft terms. Our effective lagrangian is written in terms of the spin-1/2 Goldstino (the longitudinal component of the gravitino) transforming under a non-linear realization of supersymmetry. In this lagrangian, the Goldstino is derivatively coupled and all couplings of the Goldstino to light fields are determined uniquely by the supersymmetry-breaking scale \sqrt{F}. This lagrangian is therefore a useful starting point for further investigation of the light gravitino in gauge-mediated supersymmetry breaking models. We show that the invisible width of the Z into Goldstinos gives the constraint \sqrt{F} > 140 GeV.

description: The present study aimed to evaluate the antibacterial and modulatory activity of the Turnera subulate methyl extract in isolation or in combination with aminoglycoside antibiotics, using the microdilution method. The Turnera subulata methyl extract was used in isolation in the antibacterial assays and in combination with antibiotics in the modulation assays. All tests were performed in triplicates. The Turnera subulata methyl extract presented both antibacterial and antibiotic-modulatory effects in vitro, in isolation and in association with aminoglycosides. The extract activity depends on the bacterial strain and may be associated with the presence of tannins and flavonols. However, further studies are required to characterize the Turnera subulata potential for the development of new drugs against multiresistant bacteria.

description: Chiral $p$-wave superconductor is the primary example of topological systems hosting chiral Majorana edge states. Although candidate materials exist, the conclusive signature of chiral Majorana edge states has not yet been observed in experiments. Here we propose a smoking-gun experiment to detect the chiral Majorana edge states on the basis of theoretical results for the nonlocal conductance in a device consisting of a chiral $p$-wave superconductor and two ferromagnetic leads. The chiral nature of Majorana edge states causes an anomalously long-range and chirality-sensitive nonlocal transport in these junctions. These two drastic features enable us to identify the moving direction of chiral Majorana edge states in the single experimental setup.

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.

description: Four-dimensional scanning transmission electron microscopy (4D-STEM) of local atomic diffraction patterns is emerging as a powerful technique for probing intricate details of atomic structure and atomic electric fields. However, efficient processing and interpretation of large volumes of data remain challenging, especially for two-dimensional or light materials because the diffraction signal recorded on the pixelated arrays is weak. Here we employ data-driven manifold leaning approaches for straightforward visualization and exploration analysis of the 4D-STEM datasets, distilling real-space neighboring effects on atomically resolved deflection patterns from single-layer graphene, with single dopant atoms, as recorded on a pixelated detector. These extracted patterns relate to both individual atom sites and sublattice structures, effectively discriminating single dopant anomalies via multi-mode views. We believe manifold learning analysis will accelerate physics discoveries coupled between data-rich imaging mechanisms and materials such as ferroelectric, topological spin and van der Waals heterostructures.

description: It is increasingly required that non-human animals in laboratories are provided with adequate enrichment to promote the welfare of the animals. In a previous publication we showed that laboratory dogs intensively used the horn of calf hooves as chewing objects. In this report, we describe the effect of calf horn on selected behaviors of 62 laboratory dogs (60 beagles, two Foxhound crossbreds) in three research facilities (A, B, C). In addition, we assessed the dogs’ tooth condition and fecal consistency. The selected behaviors: “aggressive behavior,” “mounting,” “tussle,” “coprophagy,” “manipulation” of the equipment and “abnormal behavior” did not change. In facilities A and C, the dogs receiving horn showed a significant reduction in staying near the fence of the kennel and observing the outside area. By analyzing the overall behavior in facility B, we found that “exploration” increased with horn, whereas “inactivity,” “social play” and “other social behavior” decreased. In conclusion, the results indicate that horn of calf hooves offers alternative stimulation. We found positive effects on tartar/plaque reduction and fecal consistency which should be confirmed in further studies.

description: In this work we want to enhance the calculation performed by Franz, Parisi and Virasoro (FPV) to estimate the free energy cost of interfaces in spin glasses and evaluate the lower critical dimension at which replica symmetry is restored. In particular we evaluate the free energy cost for a general class of effective Hamiltonians showing full replica symmetry breaking, and study the dependence of this cost on the order parameter and on the temperature. We confirm the findings of the FPV papers for the scaling of the free energy, recovering a value for the lower critical dimension of $D_{lc} = 2.5$. In addition to their results we find a non-trivial dependence of the free energy density cost on the order parameter and the temperature. Apart from the case of a restricted class of effective Hamiltonians this dependence cannot be expressed in terms of functions with a clear physical interpretation, as is the case in hierarchical models. In addition we connect the results on the lower critical dimension with recent simulations.

description: Teachers play a vital role in shaping the lives of our children. In Australia, the teaching work force is experiencing a teacher shortage especially in particular subject areas of science, technology, engineering and mathematics. Teacher retention rate is decided by teachers' outflow i.e. teachers permanently leaving the profession prior to retirement. This research uses the Staff in Australia's Schools 2010 data set as the data base to formulate a logistic regression model of teacher outflow, which enriches the quantitative research into Australian teaching work force planning.

description: We have measured the ultrafast anisotropic optical response of highly doped graphene to an intense single cycle terahertz pulse. The time profile of the terahertz-induced anisotropy signal at 800 nm has minima and maxima repeating those of the pump terahertz electric field modulus. It grows with increasing carrier density and demonstrates a specific nonlinear dependence on the electric field strength. To describe the signal, we have developed a theoretical model that is based on the energy and momentum balance equations and takes into account optical phonons of graphene and substrate. According to the theory, the anisotropic response is caused by the displacement of the electronic momentum distribution from zero momentum induced by the pump electric field in combination with polarization dependence of the matrix elements of interband optical transitions.

description: The stability properties and perturbation-induced dynamics of the full set of stationary states of the nonlinear Schroedinger equation are investigated numerically in two physical contexts: periodic solutions on a ring and confinement by a harmonic potential. Our comprehensive studies emphasize physical interpretations useful to experimentalists. Perturbation by stochastic white noise, phase engineering, and higher order nonlinearity are considered. We treat both attractive and repulsive nonlinearity and illustrate the soliton-train nature of the stationary states.

Incomplete descriptions and relevant entropies

Year: 1999
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: Statistical mechanics relies on the complete though probabilistic description of a system in terms of all the microscopic variables. Its object is to derive therefrom static and dynamic properties involving some reduced set of variables. The elimination of the irrelevant variables is guided by the maximum entropy criterion, which produces the probability law carrying the least amount of information compatible with the relevant variables. This defines relevant entropies which measure the missing information (the disorder) associated with the sole variables retained in an incomplete description. Relevant entropies depend not only on the state of the system but also on the coarseness of its reduced description. Their use sheds light on questions such as the Second Law, both in equilibrium an in irreversible thermodynamics, the projection method of statistical mechanics, Boltzmann's \textit{H}-theorem or spin-echo experiment.

description: We have calculated the electron density maps of the ripple phase of dimyristoylphosphatidylcholine (DMPC) and palmitoyl-oleoyl phosphatidylcholine (POPC) multibilayers at different temperatures and fixed relative humidity. Our analysis establishes, for the first time, the existence of an average tilt of the hydrocarbon chains of the lipid molecules along the direction of the ripple wave vector, which we believe is responsible for the occurrence of asymmetric ripples in these systems.
Charmonia production in hadron colliders and the extraction of colour-octet matrix elements

description: We present the results of our analysis on charmonia ($J/ψ$ and $ψ'$) hadroproduction taking into account higher-order QCD effects induced by initial-state radiation in a Monte Carlo framework, with the colour-octet mechanism implemented in the event generation. We find that those colour-octet matrix elements extracted so far from Fermilab Tevatron data for both $J/ψ$ and $ψ'$ production have to be lowered significantly. We finally make predictions for charmonia production at the LHC, presenting a code for a fast simulation with PYTHIA based on the colour-octet model.

description: One of the main targets for ground-based gravitational wave (GW) detectors such as Advanced LIGO (Laser Interferometer Gravitational wave Observatory) and Virgo is coalescences of neutron star (NS) binaries. Even though a NS's macroscopic properties such as mass and radius have been obtained from electro-magnetic wave observations, its internal structure has been studied mainly by using theoretical approaches. However, with the advent of Advanced LIGO and Virgo, the tidal deformability of a NS, which depends on the internal structure of the NS, has been recently obtained from GW observations. Therefore, reducing the measurement error of tidal deformability as small as possible in the GW parameter estimation is important. In this study, we introduce a post-Newtonian (PN) gravitational waveform model in which the tidal deformability contribution appears from 5 PN order, and we use the Fisher matrix (FM) method to calculate parameter measurement errors. Because the FM is computed semi-analytically using the wave function, the measurement errors can be obtained much faster than those of practical parameter estimations based on Markov Chain Monte Carlo method. We investigate the measurement errors for mass and tidal deformability by applying the FM to the nonspinning TaylorF2 waveform model. We show that if the tidal deformability corrections are considered up to the 6 PN order, the measurement error for the dimensionless tidal deformability can be reduced to about $75 \%$ compared to that obtained by considering only the 5 PN order correction.

Neutron diffraction evidence of microscopic charge inhomogeneities in the CuO2 plane of superconducting La2-xSrxCuO4 (0 < x <0.30)

description: We present local structural evidence supporting the presence of charge inhomogeneities in the CuO2 planes of underdoped La2-xSrxCuO4. High-resolution atomic pair distribution functions have been obtained from neutron powder diffraction data over the range of doping 0 < x < 0.30 at 10 K. Despite the average structure getting less orthorhombic we see a broadening of the in-plane Cu-O bond distribution as a function of doping up to optimal doping. Thereafter the peak abruptly sharpens. Complementary evidence is also evident from the observation of octahedral tilt disorder in the PDF at higher atomic separation. This suggests a crossover from a charge inhomogeneous state at and below optimal doping to a homogeneous charge state above optimal doping. The strong response of the local structure to the charge-state implies a strong electron-lattice coupling in these materials.

title: How Is the University Influenced by Neoliberalism? The Composition and Practice of Accountability in Taiwan Higher Education.
Creators: name: Peng, Ming-Te
Publisher: name: Goldsmiths, University of London
Year: 2023

description: This project aims to illustrate procedures by which academic reality has been established in the neoliberal era rather than treating the neoliberal movement as a black box. Taking universities in Taiwan as a case, this thesis draws on Foucauldian theories and Actor-Network theory to investigate how the neoliberal discourse has been enacted within the academy. My first empirical chapter focuses on the problematisation of academic practices. By investigating historical and political configurations where policy on academic governance and higher education had emerged, this research suggests that the sector of higher education has always been an object of government in Taiwan, but models of governing universities have changed in various periods. The switch from direct supervision to marketisation represents a transition in the exercise of power from sovereign power to governmentality. The second empirical chapter aims to elaborate various narratives towards higher education under the one dominant neoliberal discourse. Through discussions on contemporary concerns about globalising higher education, university industry collaboration and university’s social responsibility, a variety of narratives are identified, representing the existence of alternative frameworks of seeing higher education and possibility of resistance against the neoliberalising university. By contrast, the third empirical chapter emphasises how the neoliberal discourse gained authority through its circulation within academic organisations. With those institutional practices, the imaginary of the neoliberal university has been actualised by individual scholars, turning it into a reality. In sum, this research suggests that the dominant position of neoliberal discourse should not be considered the status quo but a temporary result of continuous neoliberal practices in which a range of actors take part. It is better to understand the neoliberal movement as heterogeneous attempts at change rather than a single or universal essence. This study also indicates that bibliometric measures play indispensable roles in these changes. First, bibliometrics contribute to the accumulation of subject knowledge regarding academic behaviour. Second, they provide a ground for individuals to interpret and to build the academic world.
