description: We explicitly show that the net number of degrees of freedom in the two-dimensional dilaton gravity is zero through the Hamiltonian constraint analysis. This implies that the local space-time dependent physical excitations do not exist. From the linear perturbation around the black hole background, we explicitly prove that the exponentially growing mode with time is in fact eliminated outside the horizon. Therefore, the two-dimensional dilation gravity is essentially stable.

description: In some supersymmetric extensions of the Standard Model fairly light superpartner of t-quark is predicted, which may form bound states - stoponiums. We estimate potentials of TESLA linear collider in search for stoponium, considering the basic e+e- option and the gamma-gamma option (Photon Linear Collider - PLC). It is found that PLC could be the best machine for discovery of these new narrow strong resonances. It can produce thousands stoponiums per 100 fb$^-1$ integrated luminosity in the high energy peak. In the case of scenarios when stoponium decays mainly into gluons the signal/background ratio is about 1/4. The channel S->hh into two lightest Higgs bosons could be also seen with high significance. Thus, several weeks run is sufficient for the stoponium discovery, if its mass is approximately known (e.g. from observation of direct stops production at LHC). Then, in MSSM scenarios with dominant S->hh decay PLC shows excellent possibilities to discover bound state of stops, practically immediately after beginning of operating. The e+e- option also has some prospects to observe stoponium but only in the case of scenarios with dominant decay into two lightest Higgs bosons, with tens of events per 100 $fb^{-1}$. Interesting possibility appears in the case when the resonance is seated on 0.1% width luminosity peak - one could resolve the stoponium exited states.

The ultimate state of Rayleigh-Bénard convection?
Creators: name: Tanabe, Aya
Publisher: name: Imperial College London
Year: 2007

description: Some scientists have performed direct numerical simulations (DNS) of homogeneous Rayleigh-Bénard (RB) convection to seek an asymptotic high-Rayleigh number heat transport scaling law Nu ~ Raγ. By applying periodic boundary conditions, the goal has been to focus on the ‘ultimate’ regime where boundary layers are negligible and convective heat transport is limited only by the turbulence in the bulk. The value γ = 1/ 2 obtained in the DNS is consistent with the analytical conjecture established in the past several decades. However, it should be pointed out that the tri-periodic model possesses exact exponentially growing solutions which transport unlimited heat. Such runaway solutions and their possible secondary instabilities are manifest above a critical Ra in the DNS. Thus, the relevance of computations on tri-periodic domains as models for the RB ultimate state is arguable. In this thesis, to understand the secondary instability mechanism, four systems have been constructed by (1) multiple scalings based on the aspect-ratio of the growing modes; (2) a modal truncation of the dynamical equations for the exact exploding solutions; (3) random noisy horizontal velocity fields; (4) a combination of the modal truncation and multiple scalings (two time-scales). Numerical studies of (1), (2) and (3) have revealed that, respectively, the growing modes are unbounded; boundedness or unboundedness is uncertain; unbounded if the noise strength is small. (4) suggests that when the nonlinear terms are dominant in the governing equations, there exist several constants of the motion for the ODEs obtained by modal truncations. This is possibly one explanation of the bursting cycles of the exponentially growing solutions observed in the DNS. The latest DNS results of homogeneous RB convection (obtained from our co-workers) are also reported, which conclude that the secondary instabilities observed in the earlier homogeneous RB DNS might be caused by numerical errors.

Behaviour of a conducting drop in a viscous fluid subject to an electric field
Creators: name: Dubash, Neville
Publisher: name: Imperial College London
Year: 2007

description: The slow deformation of a conducting drop surrounded by a viscous insulating fluid subject to a uniform electric field is considered. Two analytic models are presented for inviscid drops. The first makes use of a time-evolving spheroidal shape along with an energy balance to determine the drop behaviour. For fields below a critical value there exist equilibrium shapes. In this case, the evolution of the drop to the equilibrium shape is obtained. Above the critical value no equilibrium shapes exist and the drop has a period of slow elongation before undergoing rapid expansion. The spheroidal model is shown to be accurate up to aspect ratios of about 5. The second model uses slenderbody theory to model the drop behaviour. A similarity solution, exhibiting a finite-time singularity is obtained. Finally, detailed numerical computations, based on a boundary integral formulation, are presented for inviscid and viscous drops. The deformation of the drop right up to breakup is obtained. The type of breakup seen depends on the viscosity ratio of the drop to the surrounding fluid, and on the electric field strength. The different types of breakup seen are small droplets being emitted from the ends of the drop with a charge greater than the Rayleigh limit, the formation of what appear to be conical ends with the subsequent ejection of thin jet-like structures, or the formation of thin jet-like structures without the conical ends. Also, local analytic solutions that allow for a conical end are derived. However, none of the analytic solutions seem to correspond well with the numerical results. Finally, the behaviour of the drop near the critical electric field strength is examined in detail and time scales for the drop evolution are determined.
Hyperkähler geometry and teichmüller space
Creators: name: Hodge, Thomas Wolf Stephen

Year: 2006

description: We consider the hyperkähler extension of Teichmüller space with the Weil- Petersson metric. We describe its recent construction as a hyperkähler quotient and examine the defining equations for the resulting moduli space. We examine relations between this moduli space and the quasi-Fuchsian deformation space of the surface, with particular attention to the connection with the canonical holomorphic symplectic structure. We also consider the connection with Taubes' moduli space of hyperbolic germs and whether it is possible to extend the hyperkähler structure in any fashion.
Meson-Baryon Form Factors in Chiral Colour Dielectric Model

Publisher: name: arXiv
Year: 1998
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: The renormalised form factors for pseudoscalar meson-baryon coupling are computed in chiral colour dielectric model. This has been done by rearranging the Lippmann-Schwinger series for the meson baryon scattering matrix so that it can be expressed as a baryon pole term with renormalized form factors and baryon masses and the rest of the terms which arise from the crossed diagrams. Thus we are able to obtain an integral equation for the renormalized meson-baryon form factors in terms of the bare form factors as well as an expression for the meson self energy. This integral equation is solved and renormalized meson baryon form factors and renormalized baryon masses are computed. The parameters of the model are adjusted to obtain a best fit to the physical baryon masses. The calculations show that the renormalized form factors are energy-dependent and differ from the bare form factors primarily at momentum transfers smaller than 1 GeV. At nucleon mass, the change in the form factors is about 10% at zero momentum transfer. The computed form factors are soft with the equivalent monopole cut-off mass of about 500 MeV. The renormalized coupling constants are obtained by comparing the chiral colour dielectric model interaction Hamiltonian with the standard form of meson-nucleon interaction Hamiltonian. The ratio of $ΔNπ$ and $NNπ$ coupling constants is found to be about 2.15. This value is very close to the experimental value.

Hyperelliptic and trigonal reductions of the benney moment equations
Creators: name: Baldwin, Sadie A
Publisher: name: Imperial College London
Year: 2007

description: We consider N-parameter reductions of the Benney moment equations. These were shown in Gibbons and Tsarev (1996 Physics Letters A 211 19, 1999 Physics Letters A 258 263 ) to correspond to N−parameter families of conformal maps and to satisfy a particular system of PDE. A specific known example of this, the (N = 2) elliptic reduction (L Yu and J Gibbons 2000 Inverse Problems 16 605) is described. We then consider an analogous reduction for a genus 2 hyperelliptic curve (N = 3). The mapping function λ is given by the inversion of a 2nd kind Abelian integral on the Θ−divisor, Θ1. This is found explicitly following a method given by Enolskii, Pronine and Richter (2003 J. Nonlinear Science 13 157). Key to this is the identification of PDE satisfied on Θ1. We then consider the general case for N > 3. Again, the mapping function λ is calculated explicitly by inverting a second kind Abelian integral on the stratum Θ1 of the genus g Jacobi variety. This is done using a method based on the result of Jorgenson (1992 Isr. J Math. 77 273). The approach used for the hyperelliptic reductions is then applied to a genus 4 trigonal reduction and the function λ is calculated explicitly. A secondary result of this calculation is an expansion of the leading terms of the σ function for this family of curves.

Theoretical study of small-radius carbon nanotubes
Creators: name: Roberts, James
Publisher: name: Imperial College London
Year: 2006

description: carbon nanotubes. The energy band structure of a carbon nanotube may ordinarily be obtained by “zone-folding” the nearest neighbour tight-binding approximation of a flat graphite sheet. Due to the large curvature of a small-radius tube, however, this procedure fails to accurately predict the metallic character of any zigzag nanotube whose diameter is less than 5˚A. To this end, a third-nearest neighbour tight-binding approximation sensitive to the curvature of the tube is presented and an analytic expression for the energy bands is derived valid for all carbon nanotubes. Electron-electron interactions in small-radius zigzag carbon nanotubes are then considered by including a weak on-site Hubbard term in the tight-binding Hamilton operator. At half-filling, the system is mapped onto a set of three one-dimensional chains with alternating hopping coefficients and the low-energy physics are studied. A controlled renormalization-group analysis shows that the system flows to a strong-coupling fixed point where 1 charge mode and 2 spin modes are gapped. This fixed point also exists in the two-chain Hubbard ladder and superconducting fluctuations have previously been found to be dominant. These results support previous experimental evidence of intrinsic superconductivity in a 4˚A-diameter nanotube and suggest that both the (5, 0) and the larger (6, 0) nanotubes should be superconducting.

description: New millisecond pulsars (MSPs) in compact binaries provide a good opportunity to search for the most massive neutron stars. Their main-sequence companion stars are often strongly irradiated by the pulsar, displacing the effective center of light from their barycenter and making mass measurements uncertain. We present a series of optical spectroscopic and photometric observations of PSR J2215+5135, a "redback" binary MSP in a 4.14 hr orbit, and measure a drastic temperature contrast between the dark/cold (T$_\mathrm{N}$=5660$^{+260}_{-380}$ K) and bright/hot (T$_\mathrm{D}$=8080$^{+470}_{-280}$ K) sides of the companion star. We find that the radial velocities depend systematically on the atmospheric absorption lines used to measure them. Namely, the semi-amplitude of the radial velocity curve of J2215 measured with magnesium triplet lines is systematically higher than that measured with hydrogen Balmer lines, by 10%. We interpret this as a consequence of strong irradiation, whereby metallic lines dominate the dark side of the companion (which moves faster) and Balmer lines trace its bright (slower) side. Further, using a physical model of an irradiated star to fit simultaneously the two-species radial velocity curves and the three-band light curves, we find a center-of-mass velocity of K$_2$=412.3$\pm$5.0 km s$^{-1}$ and an orbital inclination i=63.9$^\circ$$^{+2.4}_{-2.7}$. Our model is able to reproduce the observed fluxes and velocities without invoking irradiation by an extended source. We measure masses of M$_1$=2.27$^{+0.17}_{-0.15}$ M$_\odot$ and M$_2$=0.33$^{+0.03}_{-0.02}$ M$_\odot$ for the neutron star and the companion star, respectively. If confirmed, such a massive pulsar would rule out some of the proposed equations of state for the neutron star interior.

description: The average transverse energy of nucleons and intermediate mass fragments observed in the heavy ion reaction Xe(50A MeV)+Sn shows the same linear increase as a function of their mass as observed in heavy ion collisions up to the highest ene rgies available today and fits well into the systematics. At higher energies this observation has been interpreted as a sign of a strong radial flow in an otherwise thermalized system. Investigating the reaction with Quantum Molecular dynamics simulations we find in between 50A MeV and 200A MeV a change in the reaction mechanism. At 50A MeV the apparent radial flow is merely caused by an in-plane flow and Coulomb repulsion. The average transverse fragment energy does not change in the course of the reaction and is equal to the initial fragment energy due to the Fermi motion. At 200A MeV, there are two kinds of fragments: those formed from spectator matte r and those from the center of the reaction. There the transverse energy is caused by the pr essure from the compressed nuclear matter. In both cases we observe a binary event stru cture, even in central collisions. This demonstrates as well the non thermal character of the reaction. The actual process which leads to multifragmentation is rather complex and is discussed in detail.

Cost of diagnosing a TB patient in an active case finding program using CHWs: experience from rural India

Year: 2019

description: Active case finding (ACF) holds significant potential in winning the global fight against TB. Previously employed ACF approaches such as door-to-door household surveys can incur significant costs. In contrast, rural community health workers (CHWs) become aware of the health status of their constituents as part of their routine work, e.g., home visits for maternal and child care, immunization drives, etc. Leveraging this pre-existing information can streamline identification of suspected cases, eliminating the need for exhaustive door-to-door screening.

In this poster, we demonstrate that ACF programs that utilizes existing CHW resources in the public health system are feasible, cost-efficient and do not adversely affect other health programs involving CHWs.

description: Background

Drug Susceptibility Testing (DST) is essential to a high-quality treatment program, and urgently needed to control the spread of DRTB. The increasing availability of GeneXpert machines has the potential to transform access to DST. However, the GeneXpert infrastructure runs the risk of chronic underutilization in rural contexts. E.g., in rural Indian state of Bihar, 37 Xpert machines tested 35,850 samples in 2018, a rate of 969 samples/Xpert/yr.

Interevention

A GeneXpert machine was installed to support an active-case- finding (ACF) program in three blocks (pop. 1.02 million, 630 sq. km.) of the Samastipur district (pop. 4.3M, 96% rural) in Bihar. Community health workers (CHWs) screened patients in the field to identify presumptive TB patients. All presumptive DRTB patients, presumptive EPTB patients, and pediatric patients received upfront Xpert testing, while patients with an abnormal chest X-ray and Bac+ patients received it after microscopy. We estimated a demand of 2500 tests/yr. Staffing 2 technicians allowed up to 12 hours of operation. CHWs collected sputum samples at patients' homes, and a courier brought samples to the facility. This eliminated a crucial barrier to access, and allowed better control over volume and timing. Refrigerating sputum smoothed demand spikes. The Xpert software was linked to electronic medical records to efficiently track samples and update records.

Results

From September 2017 to March 2019, 3907 samples were tested, an annualized rate of 2468 tests/yr. 907 samples (23%) were positive for TB, of which 87 (9.6%) were rifampicin-resistant (5.4/100,000 pop./yr.) In comparison, the district Xpert machine tested 2428 samples during the same period, or 1534 tests/yr. There were 128 DRTB cases (2.5/100,000 pop./yr.)

Recommendations

Utilization of the Xpert infrastructure can be significantly boosted by closer integration with frontline case-finding and diagnosis, reducing referral and travel burden, distributed sputum collection, and end-to-end electronic record management.

In particular, we focus on two classes of models where the deposition is accompanied by a local relaxation process within a distance $δ$. The models are in the Edwards-Wilkinson universality class, but the role of $δ$ is nontrivial.

description: Despite free NTP services, access is a challenge in rural India. Diagnosis requires multiple visits, and accessing the private system to fill public gaps. Treatment requires periodic travel to obtain drugs. Adherence support is limited to DOT. These barriers are reflected in the low public notification rate of 47/100,000 pop. in the rural state of Bihar, compared with 109/100,000 nationally.

An intervention was piloted in 3 blocks of (pop. 1.02M) of the Samastipur district in rural Bihar. The role of rural community health workers (CHWs, known locally as “ASHA”) was expanded from DOT supervision to assisting the patient throughout diagnosis and treatment. CHWs transported sputum to reduce patient travel. All patients received a transport allowance (USD 1.5). CHWs accompanied patients to help them navigate public services, and directed them to accredited private facilities, if needed. The program negotiated reduced prices with labs and pharmacies. Transactions were cashless - the program covered private costs (about USD 8/pt). CHWs recorded patient histories and organized lab results, facilitating the patient-physician interaction in overburdened OPDs. They administered DOT at patient homes, preventing loss of workdays due to travel to DOT centers. CHWs also helped manage side-effects, and ensured follow-up labs. They received case-finding and treatment supervision incentives, now made standard by the NTP.

We demonstrate that it is practical and cost-effective to assist patients across the care chain. Such patient-centric programs feed a virtuous cycle that builds confidence in the NTP. CHWs in rural areas offer a pathway to such comprehensive care.

Axially Symmetric Solutions for SU(2) Yang-Mills Theory

description: By casting the Yang-Mills-Higgs equations of an SU(2) theory in the form of the Ernst equations of general relativity, it is shown how the known exact solutions of general relativity can be used to give similiar solutions for Yang-Mills theory. Thus all the known exact solutions of general relativity with axial symmetry (e.g. the Kerr metric, the Tomimatsu-Sato metric) have Yang-Mills equivalents. In this paper we only examine in detail the Kerr-like solution. It will be seen that this solution has surfaces where the gauge and scalar fields become infinite, which correspond to the infinite redshift surfaces of the normal Kerr solution. It is speculated that this feature may be connected with the confinement mechanism since any particle which carries an SU(2) color charge would tend to become trapped once it passes these surfaces. Unlike the Kerr solution, our solution apparently does not have any intrinsic angular momentum, but rather appears to give the non-Abelian field configuration associated with concentric shells of color charge.

description: Баренцево море — уникальный бассейн российской Арктики, единая гидродинамической система со сложными гидрологическими и климатическими условиями. Одновременно, регион Баренцева моря испытывает антропогенное воздействие, связанное с разведкой, добычей и разработкой нефтяных месторождений в прилегающих регионах. Особенности Баренцево-Карского региона преимущественно определяются его приполюсным положением и отепляющим влиянием Северной Атлантики. Их взаимодействие инициирует большую изменчивость метеорологических параметров в течение года. В работе рассмотрены основные проблемы экологического характера в регионе Баренцева моря.

description: The processes involving low energy $\bar{K}N$ and $Yπ$ interactions (where $Y= Σ$ or $Λ$) are studied in the framework of heavy baryon chiral perturbation theory with the $Λ$(1405) resonance appearing as an independent field. The leading and next-to-leading terms in the chiral expansion are taken into account. We show that an approach which explicitly includes the $Λ$(1405) resonance as an elementary quantum field gives reasonable descriptions of both the threshold branching ratios and the energy dependence of total cross sections.

Backflow Transformations via Neural Networks for Quantum Many-Body Wave-Functions

description: Obtaining an accurate ground state wave function is one of the great challenges in the quantum many-body problem. In this paper, we propose a new class of wave functions, neural network backflow (NNB). The backflow approach, pioneered originally by Feynman, adds correlation to a mean-field ground state by transforming the single-particle orbitals in a configuration-dependent way. NNB uses a feed-forward neural network to find the optimal transformation. NNB directly dresses a mean-field state, can be systematically improved and directly alters the sign structure of the wave-function. It generalizes the standard backflow which we show how to explicitly represent as a NNB. We benchmark the NNB on a Hubbard model at intermediate doping finding that it significantly decreases the relative error, restores the symmetry of both observables and single-particle orbitals, and decreases the double-occupancy density. Finally, we illustrate interesting patterns in the weights and bias of the optimized neural network.
Young Blue Straggler Stars in the Galactic Field

Year: 2018
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: In this study we present an analysis of a sample of field blue straggler (BS) stars that show high ultra violet emission in their spectral energy distributions (SED): indication of a hot white dwarf (WD) companion to BS. Using photometry available in the Sloan Digital Sky Survey (SDSS) and Galaxy Evolution Explorer (GALEX ) surveys we identified 80 stars with UV excess. To determine the parameter distributions (mass, temperature and age) of the WD companions, we developed a fitting routine that could fit binary model SEDs to the observed SED. Results from this fit indicate the need for a hot WD companion to provide the excess UV flux. The WD mass distribution peaks at $\sim$$0.4\ M_{\odot}$, suggesting the primary formation channel of field BSs is case B mass transfer, i.e. when the donor star is in red giant phase of its evolution. Based on stellar evolutionary models, we estimate the lower limit of the binary mass transfer efficiency to be $β\sim 0.5$.

description: Background: Atrial fibrillation (AF) is a growing epidemic and evidence of a relationship to socioeconomic status (SES) is inconsistent. We aimed to summarize the literature about SES and AF and defined two objectives: (1) To examine the association between SES and the risk of AF; (2) To examine the association between SES and AF-related outcomes in an AF-population. Methods: We performed a separate search for each objective in Ovid-MEDLINE and Ovid-Embase. For objective 1, the population included was healthy participants and outcome of interest was AF. For objective 2, the population included were patients with AF and outcome of interest was mortality, treatment, ablation for AF, knowledge about AF, and morbidity. Results: For objective 1, 12 studies were included. No consistent pattern for an association between SES and the risk of AF was discovered. For objective 2, 39 studies comprising 42 outcomes were included. The majority of studies showed an association between low SES and increased mortality and morbidity. Conclusion: Low SES was associated with poorer outcomes when AF was present. These findings may imply that health-care professionals and policy interventions should focus on the promotion of AF-education and management among patients with AF and low SES.
