description: We experimentally demonstrate a source of polarization entangled photon-pairs based on a single periodically-poled potassium titanyl phosphate (PPKTP) crystal pumped with a broadband, free running laser diode.The crystal is placed within a linear beam-displacement interferometer, and emits photon-pairs based ontype-0 spontaneous parametric downconversion (SPDC). We observe pair rates of 0.56 Mpairs/s/mW in a single spatial mode with a polarization visibility of 97.7% over a spectral range of 100 nm. This experiment demonstrates a pathway towards observing Gigacount rates of polarization entangled photon pairs by using high-power free-running laser diodes with fast multiplexed detectors.

description: We consider anomaly cancellation for $SU(N)\times SU(2)\times U(1)$ gauge theories where the left-handed chiral multiplets are in higher $SU(2)$ representations. In particular, if the left-handed quarks and leptons transform under the triplet representation of $SU(2)$ and if the $U(1)$ gauge group is compact then up to an overall scaling there is only one possible nontrivial assignment for the hypercharges if $N=3$, and two if $N=9$. Otherwise there are infinitely many. We use the Mordell-Weil theorem, Mazur's theorem and the Cremona elliptic curve database which uses Kolyvagin's theorem on the Birch Swinnerton-Dyer conjecture to prove these statements.

description: Tourism in Africa was entangled with colonialism from the start. However, after the Second World War it became an integral part of the colonising powers’ development agenda, albeit one that has received little scholarly attention so far. This presented African states with a serious dilemma when most of them gained independence during the 1960s. On the one hand, tourism promised to stimulate economic growth, provide much needed foreign currency, and create employment opportunities. On the other hand, international tourism had the potential to threaten the economic independence of post-colonial states and perpetuate colonial stereotypes, as well as international and local power imbalances and inequalities. The newly elected governments had to deal with this “colonial baggage.” This article focusses on the transition from colonial to post-colonial tourism in two East African countries, Kenya and Tanzania. I explore how the late colonial government pursued tourism as a development strategy for the region. I also demonstrate how Kenya and Tanzania approached tourism and its colonial legacies in different ways after independence. To trace their respective tourism histories, I draw on published reports and newspaper articles, historical research literature, in particular, from tourism scholars of various disciplines, as well as archival sources.

description: Xenotransplantation using pig organs may be associated with the transmission of porcine viruses that could cause disease in recipients. A well-known example is the porcine cytomegalovirus, which is actually a porcine roseolovirus, hence abbreviated as PCMV/PRV. This virus is related to human herpesviruses 6 and 7 and is not closely related to human cytomegalovirus, which causes significant complications in allotransplantation [1]. PCMV/PRV has been shown to drastically reduce the survival time of porcine organs in non-human primates (for review, see [2]). The virus was also transmitted to the first patient in Baltimore who received a pig heart; it replicated exponentially to high titers in the transplanted pig heart and likely contributed to the patient’s death [3]. Therefore, the transmission of PCMV/PRV and other potentially zoonotic porcine viruses should be prevented.
Electrical control of a spin qubit in InSb nanowire quantum dots: strongly suppressed spin relaxation in high magnetic field

description: In this paper, we investigate the impact of gating potential and magnetic field on phonon induced spin relaxation rate and the speed of the electrically driven single-qubit operations inside the InSb nanowire spin qubit. We show that a strong $g$ factor and high magnetic field strength lead to the prevailing influence of electron-phonon scattering due to deformation potential, considered irrelevant for materials with a weak $g$ factor, like GaAs or Si/SiGe. In this regime, we find that spin relaxation between qubit states is significantly suppressed due to the confinement perpendicular to the nanowire axis. We also find that maximization of the number of single-qubit operations that can be performed during the lifetime of the spin qubit requires single quantum dot gating potential.

description: We consider networks for isentropic gas and prove existence of weak solutions for a large class of coupling conditions. First, we construct approximate solutions by a vector-valued BGK model with a kinetic coupling function. Introducing so-called kinetic invariant domains and using the method of compensated compactness justifies the relaxation towards the isentropic gas equations. We will prove that certain entropy flux inequalities for the kinetic coupling function remain true for the traces of the macroscopic solution. These inequalities define the macroscopic coupling condition. Our techniques are also applicable to networks with arbitrary many junctions which may possibly contain circles. We give several examples for coupling functions and prove corresponding entropy flux inequalities. We prove also new existence results for solid wall boundary conditions and pipelines with discontinuous cross-sectional area.

description: Antimicrobial peptides (AMPs) are essential immune effectors of multicellular organisms. Bacteria can evolve resistance to AMPs. Surprisingly, when used to challenge the yellow mealworm beetle, Tenebrio molitor, Staphylococcus aureus resistant to an abundant AMP (tenecin 1) of the very same host species did not increase host mortality or bacterial load compared to infections with wild-type S. aureus. A possible explanation is that antimicrobial resistance is costly due to the collaterally increased sensitivity of AMP-resistant strains to other immune effectors. Here, we study the sensitivity of a group of AMP-resistant S. aureus strains (resistant to tenecin 1 or a combination of tenecin 1 + 2) to other immune effectors such as phenoloxidase and other AMPs in vivo. Using RNAi-based knockdown, we investigate S. aureus survival in insect hosts lacking selected immune effectors. We find that all except one AMP-resistant strain displayed collateral sensitivity toward phenoloxidase. Some AMP-resistant strains show sensitivity to components of the yellow mealworm beetle AMP defense cocktail. Our findings are consistent with the idea that resistance to AMPs does not translate into changes in virulence because it is balanced by the collaterally increased sensitivity to other host immune effectors. AMP resistance fails to provide a net survival advantage to S. aureus in a host environment that is dominated by AMPs.

description: We show how exclusive vector meson production off light ions can be used to probe the spatial distribution of small-$x$ gluons in the deuteron and $^3$He wave functions. In particular, we demonstrate how short range repulsive nucleon-nucleon interactions affect the predicted coherent $J/Ψ$ production spectra. Fluctuations of the nucleon substructure are shown to have a significant effect on the incoherent cross section above $|t|\gtrsim 0.2\,\mathrm{GeV}^2$. By explicitly performing the JIMWLK evolution, we predict the $x$-dependence of coherent and incoherent cross sections in the EIC energy range. Besides the increase of the average size of the nucleus with decreasing $x$, both the growth of the nucleons and subnucleonic hot spots are visible in the cross sections. The decreasing length scale of color charge fluctuations with decreasing $x$ is also present, but may not be observable for $|t|<1\,\mathrm{GeV}^2$, if subnucleonic spatial fluctuations are present.

description: The massive Schwinger model is studied, using a density matrix renormalisation group approach to the staggered lattice Hamiltonian version of the model. Lattice sizes up to 256 sites are calculated, and the estimates in the continuum limit are almost two orders of magnitude more accurate than previous calculations. Coleman's picture of `half-asymptotic' particles at background field theta = pi is confirmed. The predicted phase transition at finite fermion mass (m/g) is accurately located, and demonstrated to belong in the 2D Ising universality class.

description: We present a strip transition-edge sensor microcalorimeter linear array detector developed for energy dispersive X-ray diffraction imaging and Compton scattering applications. The prototype detector is an array of 20 transition-edge-sensors with absorbers in strip geometry arranged in a linear array. We discuss the fabrication steps needed to develop this array including Mo/Cu bilayer, Au electroplating, and proof-of-principle fabrication of long strips of SiNx membranes. We demonstrate minimal unwanted effect of strip geometry on X-ray pulse response, and show linear relationship of 1/pulse height and pulse decay times with absorber length. For the absorber lengths studied, preliminary measurements show energy resolutions of 40 eV to 180 eV near 17 keV. Furthermore, we show that the heat flow to the cold bath is nearly independent of the absorber area and depends on the SiNx membrane geometry.

description: We present our preliminary result for the charmed quark mass, which follows from taking the D_s and K meson masses from experiment and r0=0.5 fm (or, equivalently F_K=160 MeV) to set the scale. For the renormalization group invariant quark mass we obtain M_c = 1684(64) MeV, which translates to m_c(m_c)= 1314 (40)(20)(7) MeV for the running mass in the MSbar scheme. Renormalization is treated non-perturbatively, and the continuum limit has been taken, so that the only uncontrolled systematic error consists in the use of the quenched approximation.

description: In the lightcone frame, where the supermembrane theory and the Matrix model are strikingly similar, the equations of motion admit an elegant complexification in even dimensional spaces. Although the explicit rotational symmetry of the target space is lost, the remaining unitary symmetries apart from providing a simple and unifying description of all known solutions suggest new ones for rotating spherical and toroidal membranes. In this framework the angular momentum is represented by U(1) charges which balance the nonlinear attractive forces of the membrane. We examine in detail a six dimensional rotating toroidal membrane solution which lives in a 3-torus, $T^3$ and admits stable radial modes. In Matrix Theory it corresponds to a toroidal N-$D_{0}$ brane bound state. We demonstrate its existence and discuss its radial stability.

Critical quantum fluctuations and photon antibunching in optomechanical systems with large single-photon cooperativity

description: A pertinent question in cavity optomechanics is whether reaching the regime of large single-photon cooperativity, where the single-photon coupling rate exceeds the geometric mean of the cavity and mechanical decay rates, can enable any new phenomena. We show that in some multimode optomechanical systems, the single-photon cooperativity can indeed be a figure of merit. We first study a system with one cavity mode and two mechanical oscillators which combines the concepts of levitated optomechanics and coherent scattering with standard dispersive optomechanics. Later, we study a more complicated setup comprising three cavity modes which does not rely on levitated optomechanics and only features dispersive optomechanical interactions with direct cavity driving. These systems can effectively realize the degenerate or the nondegenerate parametric oscillator models known from quantum optics, but in the unusual finite-size regime for the fundamental mode(s) when the single-photon cooperativity is large. We show that the response of these systems to a coherent optical probe can be highly nonlinear in probe power even for average photon occupation numbers below unity. The nonlinear optomechanical interaction has the peculiar consequence that the probe drive will effectively amplitude-squeeze itself. For large single-photon cooperativity, this occurs for small occupation numbers, which enables observation of nonclassical antibunching of the transmitted probe photons due to a destructive interference effect. Finally, we show that as the probe power is increased even further, the system enters a critical regime characterized by intrinsically nonlinear dynamics and non-Gaussian states.

We have used this resonance to enhance the normally suppressed p-wave collision cross-section to values larger than the background s-wave cross-section between potassium atoms in different spin-states. In addition to the modification of two-body elastic processes, the resonance dramatically enhances three-body inelastic collisional loss.

description: The bottomonium spectrum is far from being established. The structures of higher vector states, including the $Υ(10580)$, $Υ(10860)$, and $Υ(11020)$ states, are still in dispute. In addition, whether the $Υ(10750)$ signal which was recently observed by the Belle Collaboration is a normal $b\bar{b}$ state or not should be examined. Faced with such a situation, we carried out a systematic investigation of the bottomonium spectrum in the scheme of the relativistic flux tube (RFT) model. A Chew-Frautschi like formula was derived analytically for the spin average mass of bottomonium states. We further incorporated the spin-dependent interactions and obtained a complete bottomonium spectrum. We found that the most established bottomonium states can be explained in the RFT scheme. The $Υ(10750)$, $Υ(10860)$, and $Υ(11020)$ could be predominantly the $3^3D_1$, $5^3S_1$, and $4^3D_1$ states, respectively. Our predicted masses of $1F$ and $1G$ $b\bar{b}$ states are in agreement with the results given by the method of lattice QCD, which can be tested by experiments in future. We also compared the RFT model with the quark potential model in detail. The differences of these two kinds of models were discussed.

description: There are many reasons for developing school-family-community partnerships. Partnerships can improve school programs, provide services to families, increase parents’ skills, connect families and most importantly, improve and enhance pupils’ academic performance and learning experiences. This study explores stakeholders’ perceptions of family and community involvement in the education of pupils of Black Caribbean origin. It was conducted at one primary school in inner London and focused exclusively on the perceptions of stakeholders of the Black Caribbean community. The basic tenet underlying the study is that all knowledge is constructed. It therefore adopts a constructivist epistemological perspective and utilises semi-structured interviews and a focus group. This study examines why school-family-community partnerships are necessary and the challenges faced in establishing, developing and sustaining them, specifically with this group of learners, many of whom are underachieving not only in British schools but at schools worldwide. The relative underachievement of this group of pupils has been a cause for concern not only for their parents and families but for educators as well, both at the local and national levels. The research highlights that in order to give these learners the best educational outcomes; families and the community should play a key role in supporting them. The findings reveal that the school has put a number of measures in place but needs to consider how it can harness the available resources from families and from within the community to support not only this group of learners but for all learners at the school.
Structure-Function Relationship of Muscle Thin Filament Regulatory Proteins: Tropomyosin and Troponin

description: Tropomyosin and troponin are key regulatory proteins associated with muscle thin filaments. Regulation of muscle contraction by these complexes involves precise cooperative-allosteric transitions. Several diseases are associated with changes in these transitions. Understanding the structural basis of these transitions is critical to understand the details of the regulation of muscle contraction and how they are changed in various diseases. This thesis has two aims. The first aim was to investigate tropomyosin structure function relationship by mutagenesis and various biochemical assays. I performed 7 double residues’ mutations in seven semi-repeated motifs of Tropomyosin: K6K7E, K48K49E, R90R91E, R132S133E, R167K168E, N202N203E and R244S245E. I used several different biochemical and biophysical techniques such as Stopped flow, ITC, Cosedimentation, Circular dichroism and ATPase assays to study the impact of each mutation on actin and troponin binding and thin filaments cooperativity and switching between allosteric states. These mutations had little or no effect on actin binding, troponin binding and the actomyosin ATPase inhibition at low Ca2+. However, K48K49E, R90R91E, R167K168E, N202N203E and R244S245E reduced noticeably the level of activation in the presence of Ca2+. These effects could be explained by reduced cooperativity and a stabilisation of the blocked state. The effect was most pronounced with R167K168E suggesting a critical role of this motif in tropomyosin cooperative allosteric function. K6K7E affected end-to-end interaction between adjacent tropomyosin molecules and this led to reduce the cooperativity and interaction with actin and troponin. Since the structure of the full length troponin is not yet available, the second aim of this thesis was to study troponin structure-function using nuclear magnetic resonance (NMR) spectroscopy. I was able to produce 15N labelled TnC and reconstitute it with troponin I and T and obtain an HSQC spectra. However, the quality of the spectra suggests that using the full-length troponin in NMR based structural studies is still a challenge. Alternatively, I designed a short-length troponin complex and I obtained sufficient material labelled with 15N and obtained good HSQC spectra. Thus, I laid the foundation for an exciting NMR based study of the allosteric transitions in troponin.

description: We clarify the questions rised by a recent example of a lattice Dirac operator found by Chiu. We show that this operator belongs to a class based on the Cayley transformation and that this class on the finite lattice generally does not admit a nonvanishing index, while in the continuum limit, due to operator properties in Hilbert space, this defect is no longer there. Analogous observations are made for the chiral anomaly. We also elaborate on various aspects of the underlying sum rule for the index.

description: The energy spectrum for high energy $γ$-rays ($E_γ\geq 10$ MeV) from the process $pp \to γγX$ emitted at $90^0$ in the laboratory frame has been measured at 216 MeV. The resulting photon energy spectrum extracted from $γ-γ$ coincidence events consists of a narrow peak (5.3$σ$) at a photon energy of about 24 MeV and a relatively broad peak (3.5$σ$) in the energy range of (50 - 70) MeV. This behavior of the photon energy spectrum is interpreted as a signature of the exotic dibaryon resonance $d^\star_1$ with a mass of about 1956 MeV which is assumed to be formed in the radiative process $pp \to γd^\star_1$ followed by its electromagnetic decay via the $d^\star_1 \to pp γ$ mode. The experimental spectrum is compared with those obtained by means of Monte Carlo simulations.

description: Due to large QED anomalous dimensions of the electric and magnetic dipole operators, the rate of the rare muon decay mu --> e+gamma is suppressed by the factor [ 1- 8 alpha/pi ln(Lambda/m_mu) ], independent of the physics responsible for the lepton-flavor violation, except for the scale Lambda at which it occurs. For Lambda = 100 -- 1000 GeV, the resulting decrease of the rate amounts to about 12 -- 17 %.

description: At low temperatures, spinel CuIr$_2$S$_4$ is a charge-ordered spin-dimerized insulator with triclinic lattice symmetry. We find that x-rays induce a structural transition in which the local triclinic structure is preserved, but the average lattice symmetry becomes tetragonal. These structural changes are accompanied by a thousandfold reduction in the electrical resistivity. The transition is persistent, but the original state can be restored by thermal annealing. We argue that x-ray irradiation disorders the lattice dimerization pattern, producing a state in which the orientation of the dimers is preserved, but the translational long-range order is destroyed.

Primal-dual block-proximal splitting for a class of non-convex problems

description: We develop block structure adapted primal-dual algorithms for non-convex non-smooth optimisation problems whose objectives can be written as compositions $G(x)+F(K(x))$ of non-smooth block-separable convex functions $G$ and $F$ with a non-linear Lipschitz-differentiable operator $K$. Our methods are refinements of the non-linear primal-dual proximal splitting method for such problems without the block structure, which itself is based on the primal-dual proximal splitting method of Chambolle and Pock for convex problems. We propose individual step length parameters and acceleration rules for each of the primal and dual blocks of the problem. This allows them to convergence faster by adapting to the structure of the problem. For the squared distance of the iterates to a critical point, we show local $O(1/N)$, $O(1/N^2)$ and linear rates under varying conditions and choices of the step lengths parameters. Finally, we demonstrate the performance of the methods on practical inverse problems: diffusion tensor imaging and electrical impedance tomography.

We use Monte Carlo (i) to compute matrix elements of the transition amplitude and (ii) to construct stochastically a basis. The MC Hamiltonian allows to obtain energies and wave functions of low-lying states. It allows also to compute thermodynamical observables in some temperature window (starting from temperature zero). We present examples from lattice field theory (Klein-Gordon model).

description: We construct integrability-preserving deformations of the integrable $σ$-model coupling together $N$ copies of the Principal Chiral Model. These deformed theories are obtained using the formalism of affine Gaudin models, by applying various combinations of Yang-Baxter and $λ$-deformations to the different copies of the undeformed model. We describe these models both in the Hamiltonian and Lagrangian formulation and give explicit expressions of their action and Lax pair. In particular, we recover through this construction various integrable $λ$-deformed models previously introduced in the literature. Finally, we discuss the relation of the present work with the semi-homolomorphic four-dimensional Chern-Simons theory.

Large Mixing Induced by the Strong Coupling with a Single Bulk Neutrinos
Creators: name: Lam, C. S.
Publisher: name: arXiv
Year: 2001
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Neutrino is a good probe of extra dimensions. Large mixing and the apparent lack of very complicated oscillation patterns may be an indication of large couplings between the brane and a single bulk neutrino. A simple and realistic five-dimensional model of this kind is discussed. It requires a sterile in addition to three active neutrinos on the brane, all coupled strongly to one common bulk neutrino, but not directly among themselves. Mindful that sterile neutrinos are disfavored in the atmospheric and solar data, we demand induced mixing to occur among the active neutrinos, but not between the active and the sterile. The size $R$ of the extra dimension is arbitrary in this model, otherwise it contains six parameters which can be used to fit the three neutrino masses and the three mixing angles. However, in the model those six parameters must be suitably ordered, so a successful fit is not guaranteed. It turns out that not only the data can be fitted, but as a result of the ordering, a natural connection between the smallness of the reactor angle $θ_{13}$ and the smallness of the mass-gap ratio $ΔM^2_{solar}/ΔM^2_{atmospheric}$ can be derived.

description: We report on a fully bi-directional 680~km fiber link connecting two cities for which the equipment, the set up and the characterization are managed for the first time by an industrial consortium. The link uses an active telecommunication fiber network with parallel data traffic and is equipped with three repeater laser stations and four remote double bi-directional Erbium-doped fiber amplifiers. We report a short term stability at 1~s integration time of $5.4\times 10^{-16}$ in 0.5~Hz bandwidth and a long term stability of $1.7\times10^{-20}$ at 65\,000 s of integration time. The accuracy of the frequency transfer is evaluated as $3\times 10^{-20}$. No shift is observed within the statistical uncertainty. We show a continuous operation over 5 days with an uptime of 99.93$\%$. This performance is comparable with the state of the art coherent links established between National Metrology Institutes in Europe. It is a first step in the construction of an optical fiber network for metrology in France, which will give access to an ultra-high performance frequency standard to a wide community of scientific users.
