description: We consider the quantum scattering from a random potential of strength $λ^{1/2}$ and with a support on the scale of the mean free path, which is of order $λ^{-1}$. On the basis of maximally crossed diagrams we provide a concise formula for the backscattering rate in terms of the Green's function for the kinetic Boltzmann equation. We briefly discuss the extension to wave scattering.

description: The retrieval approach is currently a standard method for deriving atmospheric properties from observed spectra of exoplanets. However, the approach ignores disequilibrium chemistry in most current retrieval codes, which can lead to misinterpretation of the metallicity or elemental abundance ratios of the atmosphere. We have implemented the disequilibrium effect of vertical mixing or quenching for the major species in hydrogen/helium-dominated atmospheres, namely $\mathrm{CH_4}$, $\mathrm{CO}$, $\mathrm{H_2O}$, $\mathrm{NH_3}$, $\mathrm{N_2}$, and $\mathrm{CO_2}$, for the spectral retrieval code ARCiS with a physical basis using the chemical relaxation method. Then, using ARCiS updated with this module, we have performed retrievals of the observed transmission spectra of 16 exoplanets with sizes ranging from Jupiter to mini-Neptune. As a result, we find indications of disequilibrium chemistry for HD 209458b ($\geq 4.1σ$) and WASP-39b ($\geq 2.7σ$). The retrieved spectrum of HD 209458b exhibits a strong $\mathrm{NH_3}$ absorption feature at 10.5 $μ$m accessible by JWST owing to an enhanced abundance of $\mathrm{NH_3}$ due to the quenching effect. This feature is absent in the spectrum retrieved assuming equilibrium chemistry, which makes HD 209458b an ideal target for studying disequilibrium chemistry in exoplanet atmospheres. Moreover, for HAT-P-11b and GJ 436b, we obtain relatively different results than for the retrieval with the equilibrium assumption, such as a $2.9σ$ difference for the C/O ratio. We have also examined the retrieved eddy diffusion coefficient, but could not identify a trend over the equilibrium temperature, possibly due to the limits of the current observational precision.

description:
 In this paper, a robot has been designed and implemented to move in four main directions by voice commands. The robot consists of a HC-5 Bluetooth receiver module, an Atmega8a microcontroller, a L293d motor driver and two regulators. 2 seconds voice were recorded from 5 different subjects and preprocessed by a Butterworth bandpass filter. A Frequency feature was extracted from the operator's voice and it has been classified by KNN and ANN classifiers with different structures. The performance of ANN was better in comparison to the KNN classifier. Also when the network trained with one person and test with the same person the accuracy was higher. The best result was for ANN classifier with 12 neurons in the hidden layer when the input data were windowed and it was 90.7±3.1% accuracy. finally, the outputs of the classifier send to the robot via Bluetooth module and the robot is moved in the desired direction for 3 seconds.

description: The decoy-state method is a standard enhancement to quantum key distribution (QKD) protocols that has enabled countless QKD experiments with inexpensive light sources. However, new technological advancements might require further theoretical study of this technique. In particular, the decoy-state method is typically described under the assumption of a Poisson statistical distribution for the number of photons in each QKD pulse. This is a practical choice, because prepare-and-measure QKD is often implemented with attenuated lasers, which produce exactly this distribution. However, sources that do not meet this assumption are not guaranteed to be compatible with decoy states. In this work, we provide security bounds for decoy-state QKD using a source with an arbitrary photon emission statistic. We consider both the asymptotic limit of infinite key and the finite-size scenario, and evaluate two common decoy-state schemes: the vacuum+weak and one-decoy protocols. We numerically evaluate the performance of the bounds, comparing three realistic statistical distributions (Poisson, thermal, binomial), showing that they are all viable options for QKD.

description: I briefly survey here attempts to model the rich and strange behaviour of colossal magnetoresistance manganites, after outlining some of the phenomena observed in them, and describing the three relevant strong local interactions of the e_g electrons (in two different orbital states at each site), namely with Jahn-Teller phonon modes (strength g), with resident t_2g spins (ferromagnetic Hund's rule coupling J_H) and amongst each other (the Mott Hubbard correlation U) . A new two fluid model of nearly localized l polarons and band (b) electrons for low energy behaviour emerges for large g; some of its applications are mentioned here. I describe some results of strong coupling U, J_H calculations in single site DMFT (Dynamical Mean Field Theory), and show that in the wide orbital liquid regime many characteristic manganite phenomena such as an insulating ferromagnetic ground state, thermal insulator metal transition, colossal magnetoresistance (cmr), materials systematics and the observed low effective carrier density can all be understood qualitatively and quantitatively. We also discuss the two 'phase' coexistence frequently found in these systems, and show that electrostatic coulomb interactions mute lb phase separation into nanoscale electronic inhomogeneity with l regions and b puddles. Finally, some problems of current interest as well as general ones arising, eg polarons and the physics of large electron phonon coupling g in the adiabatic regime, are mentioned.

description: This paper proposes a metric for sets of trajectories to evaluate multi-object tracking algorithms that includes time-weighted costs for localisation errors of properly detected targets, for false targets, missed targets and track switches. The proposed metric extends the metric in [1] by including weights to the costs associated to different time steps. The time-weighted costs increase the flexibility of the metric [1] to fit more applications and user preferences. We first introduce a metric based on multi-dimensional assignments, and then its linear programming relaxation, which is computable in polynomial time and is also a metric. The metrics can also be extended to metrics on random finite sets of trajectories to evaluate and rank algorithms across different scenarios, each with a ground truth set of trajectories.

description: We report experimental results of the field-induced variations of the microwave surface resistance in samples of MgB2, produced by different methods. By sweeping the DC magnetic field at increasing and decreasing values, we have detected a magnetic hysteresis that can be ascribed to the different magnetic induction, due to the critical state of the fluxon lattice. The hysteresis observed in the bulk samples has an unusual shape, which cannot be justified in the framework of the critical-state models.

description: Momentum transfer from light to matter provides the basic principle of optical tweezers, which have been awarded the Nobel Prize in Physics 2018.[1] Most studies have hitherto employed this principle for trapping and manipulation of single nanoparticles. However, in a microfluidic channel one can also monitor the effect of optical forces exerted on ensembles of dielectric nanoparticles, to acquire knowledge about various nanoparticle parameters, such as size, shape or material distributions. In this paper we present an optofluidic force induction scheme (OF2i) for real-time, on-line optical characterization of large ensembles of nanoparticles.[2] Our experimental setup builds on precisely controlled fluidics as well as optical elements, in combination with a focused laser beam with orbital angular momentum. By monitoring the single-particle light scattering and nanoparticle trajectories, we obtain detailed number-based information about the properties of the individually tracked particles. We analyse the trajectories using a simulation approach based on Maxwell’s equati­ons and Mie’s theory, in combination with realistic laser fields and fluidic forces.[3] We discuss the basic physical principles underlying the OF2i scheme and demonstrate its applicability using standardized Latex particles with a pre-determined size distribution as calibration reference. Our measurement scheme is applied to different particle systems and evaluated within our theoretical framework, where we also monitor evolutionary processes over large time scales. Our results prove that OF2i provides a flexible work bench for numerous pharmaceutical and technological applications, as well as medical diagnostics. [1] Ashkin A., PNAS 1997, 94, 4853-4860. [2] C.

The genetic analysis of factors influencing the lethality associated with the scute inversions of Drosophila melanogaster
Creators: name: Johnson, Carey
Publisher: name: University of British Columbia
Year: 2010

description: It has been previously established that inviability is associated with X/0 males carrying a scute inversion X chromosome. Explanations of this phenomenon suggest that the lethality may be due to a position effect suppression of the rRNA cistrons. This thesis provides an alternative explanation of the scute X/0 lethality and provides support for the primary function of the scute locus. These studies indicate that the lethality associated with the scute X/0 genotype is conditional and dependent upon the parental origin of the X chromosome. Numerous experiments indicate that the lethality results from a disfunction of the scute locus rather than the rRNA cistrons.

description: High peak power ultrafast lasers are widely used in nonlinear spectroscopy but often limit its spectral resolution because of the broad frequency bandwidth of ultrashort laser pulses. Improving the resolution by achieving spectrally narrow excitation of, or emission from, the resonant medium by means of multi-photon interferences has been the focus of many recent developments in ultrafast spectroscopy. We demonstrate an alternative approach, in which high resolution is exercised by detecting narrow spectral correlations between broadband excitation and emission optical fields. All-optical correlation analysis, easily incorporated into the traditional spectroscopic setup, enables direct, robust and simultaneous detection of multiple narrow resonances with a single femtosecond pulse.

description: In 2002, V838 Monocerotis (V838 Mon) erupted in a red novae event which has been interpreted to be a stellar merger. Soon after reaching peak luminosity, it began to cool, and its spectrum evolved to later spectral types. Dust was also formed in the post-merger remnant, making it bright in the mid-infrared. Interferometric studies at these wavelengths have suggested the presence of a flattened, elongated structure. We investigate, for the first time, the structure and orientation of the dusty envelope surrounding V838 Mon in the $L$(2.8-4.2 $μ$m) band using recent observations with the MATISSE instrument at the VLTI. We perform simple geometrical modelling of the interferometric observables using basic models (disks, Gaussians, point sources, along with their combinations). We also reconstructed an image and analyzed the corresponding $L$-band spectrum. This study indicates the presence of an elongated, disk-like structure near 3.5$μ$m, similar to what has been observed in other wavelength regimes. In particular, the orientation at a position angle of -40 degrees agrees with prior measurements in other bands. The dusty elongated structure surrounding V838 Mon appears to be a stable and long lived feature that has been present in the system for over a decade. Its substructure and origin remain unclear, but may be related to mass loss phenomena that took place in the orbital plane of the merged binary.

description: DiverIMPACTS will produce data that include data from measurements carried oud in a network of 10 field experiments. This network was built across Europe (7 countries) covering a range of pedo-climatic conditions and different farming systems: arable and vegetable systems both under conventional and organic management. Each field experiment will test one or several diversified cropping systems combining three strategies of diversification with low input practices compared to a reference system less diversified and more dependent on external inputs. The three strategies of crop diversification are a) rotation, b) multiple-cropping (growing different crop species on the same land within a growing season) and c) intercropping (growing different species in proximity in the same field. The WP3 database must give an access to information that could help diversification initiatives by the demonstration of the multiple benefits of different strategies of diversification (in time and space) at the cropping system level and the decision rules for their design and their management in different contexts This deliverable explains: the type of data and metadata collected in this network the structure of the data base and tools the structure of the field experiment data base
Minimum perihelion distances and associated dwell times for near-Earth asteroids

description: The observed near-Earth asteroid population contains very few objects with small perihelion distances, say, q<=0.2 au. NEAs that currently have orbits with larger q might be hiding a past evolution during which they have approached closer to the Sun. We present a probabilistic assessment of the minimum q that an asteroid has reached during its orbital history. At the same time, we offer an estimate of the dwell time, that is, the time q has been in a specific range. We have re-analyzed orbital integrations of test asteroids from the moment they enter the near-Earth region until they either collide with a major body or are thrown out from the inner Solar System. We considered a total disruption of asteroids at certain q as a function of absolute magnitude (H). We calculated the probability that an asteroid with given orbital elements and H has reached a q smaller than a given threshold value and its respective dwell time in that range. We have constructed a look-up table that can be used to study the past orbital and thermal evolution of asteroids as well as meteorite falls and their possible parent bodies. An application to 25 meteorite falls shows that carbonaceous chondrites typically have short dwell times at small q, whereas for ordinary chondrites it ranges from 10,000 to 500,000 years. A dearth of meteorite falls with long dwell times and small minimum q supports a super-catastrophic disruption of asteroids at small q.

description: Integrated light from distant galaxies is often compared to stellar population models via the equivalent widths of spectral features--spectral indices--whose strengths rely on the abundances of one or more elements. Such comparisons hinge not only on the overall metal abundance but also on relative abundances. Studies have examined the influence of individual elements on synthetic spectra but little has been done to address similar issues in the stellar evolution models that underlie most stellar population models. Stellar evolution models will primarily be influenced by changes in opacities. In order to explore this issue in detail, twelve sets of stellar evolution tracks and isochrones have been created at constant heavy element mass fraction Z that self-consistently account for varying heavy element mixtures. These sets include scaled-solar, alpha-enhanced, and individual cases where the elements C, N, O, Ne, Mg, Si, S, Ca, Ti, and Fe have been enhanced above their scaled-solar values. The variations that arise between scaled-solar and the other cases are examined with respect to the H-R diagram and main sequence lifetimes.

description: In the near future there will be the request for very large liquid Xenon (LXe) detectors for Dark Matter (DM) searches in the 50-ton range. To avoid an impractically long, single drift space of a dual-phase detector, it seems beneficial to use the single-phase technique. Since electrons then can drift in any direction, we can segment the homogeneous medium and thus avoid an excessive maximum drift path of order 4 m. The shorter detector length has several benefits, e.g. requiring a lower cathode voltage for the same drift field. We can easily split the TPC into two regions with the cathode in the center and two anodes at the top and bottom. One also can use multiple TPCs stacked on top of each other in the same liquid volume to reduce the maximum drift length even further. A further division of the drift space by installing an additional anode in the center would require S2 photons to traverse the liquid for several times the Rayleigh scattering length in LXe, which is only 30 - 40 cm. This seems to be excessive for good x - y localization. We therefore suggest a geometry of two independent TPCs with two drift spaces each. Despite earlier publications concerns persisted about the effect of shadowing. A detailed FEM model of the anode regions shows that with an aligned wire arrangement the drifting electrons impinge sideways on the anode in a narrow angular range of width 15$^{\circ}$ - 20$^{\circ}$. Most S2 photons are emitted in full view of the close-by PMT array. About 37% of the S2 photons are shadowed by the anode wire out of which 30\% will be reflected back again on the gold plating of the wires. Thus we can observe 74% of the total S2 light. Compared to a dual-phase detector, however, we do not suffer from the extraction efficiency, sometimes reported as low as 50%.

Particle hopping on a ladder: exact solution using multibalance
Creators: name: Mukherjee, Indranil
Publisher: name: arXiv
Year: 2021
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: We study particle hopping on a two-leg ladder where a particle can jump to their immediate neighbours, one at a time, with rates that depend on the occupation of the departure site and a neighbouring site on the other leg. For specific choices of rates, the model can be solved using pairwise balance known earlier. For the other regimes, we introduce a new balance condition called multibalance which helps us in obtaining the exact steady state. The direction of the total current in these models does not necessarily decide the direction of the currents in individual legs; we find the regions in the parameter space where the currents in individual legs alter their direction. In some parameter regime, the total current exhibits the re-entrance phenomena, in the sense that the total current flips its direction with increase of certain parameter and flips it again when the parameter is increased further. It turns out that the multibalance condition we introduce here is very useful and it can be applied generically to several other models. We discuss some of these models in short.

Finite-size effects on a lattice calculation

description: We study in this paper the finite-size effects of a non-periodic lattice on a lattice calculation. To this end we use a finite lattice equipped with a central difference derivative with homogeneous boundary conditions to calculate the bosonic mass associated to the Schwinger model. We found that the homogeneous boundary conditions produce absence of fermion doubling and chiral invariance, but we also found that in the continuum limit this lattice model does not yield the correct value of the boson mass as other models do. We discuss the reasons for this and, as a result, the matrix which cause the fermion doubling problem is identified.

description: We consider learning an undirected graphical model from sparse data. While several efficient algorithms have been proposed for graphical lasso (GL), the alternating direction method of multipliers (ADMM) is the main approach taken concerning for joint graphical lasso (JGL). We propose proximal gradient procedures with and without a backtracking option for the JGL. These procedures are first-order and relatively simple, and the subproblems are solved efficiently in closed form. We further show the boundedness for the solution of the JGL problem and the iterations in the algorithms. The numerical results indicate that the proposed algorithms can achieve high accuracy and precision, and their efficiency is competitive with state-of-the-art algorithms.

Urban planning in the developing countries: the use of quantitative planning methods
Creators: name: Kumapley, Frank Titus Kofi
Publisher: name: University of British Columbia
Year: 2010

description: The relevance of western planning models to urban processes in the developing countries is a topic which has engaged the attention of many planners. In this study, three commonly used quantitative planning methods are evaluated with respect to the circumstances under which they may be used, and what results may be expected from applying them to urban planning operations in the developing countries. The three methods evaluated are: the Cohort-Survival Method of population forecasting; the Urban Economic Base model; and the Gravity Models of Spatial Interaction. The study uses the structural analysis approach to model evaluation. In this approach, the decisive factor is the ability of the model being evaluated to adequately answer, or provide information on, relevant planning questions which are characteristic of cities in the developing countries. The author arrives at the following major findings and conclusions: i) that the main deterrent to any possible use of the Cohort-Survival model in the developing countries is the difficulty of estimating the migration vector; ii) that the structure and the relatively small base-ratios of urban economies in the developing countries greatly reduce the potential of the Economic Base model to the extent that it can be considered irrelevant to cities in these countries; iii) that instabilities in travel patterns, imperfections in urban housing markets and the existence of periodic systems of marketing in the developing countries create circumstances which are seemingly very difficult to handle within the presently known theoretical framework of the Gravity models of intra-urban trip distribution, residential location and retail location, respectively; iv) that, in view of the above findings, three main factors may be used to explain the difficulty of transferring western planning methods to the developing countries. These include: (a) differences in cultural and economic environments; (b) differences in rates of urban growth; and (c) differences in the degree of difficulty in obtaining the necessary data. To overcome the difficulties of using the three models evaluated in the developing countries, a number of both short- and long-term measures are suggested. The short-term measures, which are specific to each of the three models, concentrate on identifying alternative approaches and sources of information for use by planners faced with the problems of city development in the developing countries. Finally, the author contends that if long-run solutions are to be found to the problems of planning methodology transfer by evolving and using locally relevant planning techniques, then measures such as increased planning research closely matched by improvements in planning data base and administration are required.

X-ray analysis of the Planck-detected triplet-cluster system PLCK G334.8-38

description: We conducted an X-ray analysis of one of the two Planck-detected triplet-cluster systems, PLCK G334.8-38.0, with a $\sim100$~ks deep XMM-Newton data. We find that the system has a redshift of $z=0.37\pm{0.01}$ but the precision of the X-ray spectroscopy for two members is too low to rule out a projected triplet system, demanding optical spectroscopy for further investigation. In projection, the system looks almost like an equilateral triangle with an edge length of $\sim2.0\,\mathrm{Mpc}$, but masses are very unevenly distributed ($M_{500} \sim [2.5,0.7,0.3] \times 10^{14}\,\mathrm{M_{\odot}}$ from bright to faint). The brightest member appears to be a relaxed cool-core cluster and is more than twice as massive as both other members combined. The second brightest member appears to be a disturbed non-cool-core cluster and the third member was too faint to make any classification. None of the clusters have an overlapping $R_{500}$ region and no signs of cluster interaction were found; however, the XMM-Newton data alone are probably not sensitive enough to detect such signs, and a joint analysis of X-ray and the thermal Sunyaev-Zeldovich effect (tSZ) is needed for further investigation, which may also reveal the presence of the warm-hot intergalactic medium (WHIM) within the system. The comparison with the other Planck-detected triplet-cluster-system (PLCK G214.6+36.9) shows that they have rather different configurations, suggesting rather different merger scenarios, under the assumption that they are both not simply projected triplet systems.

description: Measurement-device-independent quantum key distribution (MDI-QKD) can eliminate all detector side-channel loopholes and has shown excellent performance in long-distance secret keys sharing. Conventional security proofs, however, require additional assumptions on sources and that can be compromised through uncharacterized side channels in practice. Here, we present a general formalism based on reference technique to prove the security of MDI-QKD against any possible sources imperfection and/or side channels. With this formalism, we investigate the asymptotic performance of single-photon sources without any extra assumptions on the state preparations. Our results highlight the importance of transmitters' security.

Three-Dimensional Percolation Modeling of Self-Healing Composites

description: We study the self-healing process of materials with embedded "glue"-carrying cells, in the regime of the onset of the initial fatigue. Three-dimensional numerical simulations within the percolation-model approach are reported. The main numerical challenge taken up in the present work, has been to extend the calculation of the conductance to three-dimensional lattices. Our results confirm the general features of the process: The onset of the material fatigue is delayed, by developing a plateau-like time-dependence of the material quality. We demonstrate that in this low-damage regime, the changes in the conductance and thus, in similar transport/response properties of the material can be used as measures of the material quality degradation. A new feature found for three dimensions, where it is much more profound than in earlier-studied two-dimensional systems, is the competition between the healing cells. Even for low initial densities of the healing cells, they interfere with each other and reduce each other's effective healing efficiency.
