description: The dynamics of exciton recombination in an ensemble of indirect band-gap (In,Al)As/AlAs quantum dots with type-I band alignment is studied. The lifetime of confined excitons which are indirect in momentum-space is mainly influenced by the sharpness of the heterointerface between the (In,Al)As quantum dot and the AlAs barrier matrix. Time-resolved photoluminescence experiments and theoretical model calculations reveal a strong dependence of the exciton lifetime on the thickness of the interface diffusion layer. The lifetime of excitons with a particular optical transition energy varies because this energy is obtained for quantum dots differing in size, shape and composition. The different exciton lifetimes, which result in photoluminescence with non-exponential decay obeying a power-law function, can be described by a phenomenological distribution function, which allows one to explain the photoluminescence decay with one fitting parameter only.

description: DMRG ground state search algorithms employing symmetries must be able to expand virtual bond spaces by adding or changing symmetry sectors if these lower the energy. Traditional single-site DMRG does not allow bond expansion; two-site DMRG does, but at much higher computational costs. We present a controlled bond expansion (CBE) algorithm that yields two-site accuracy and convergence per sweep, at single-site costs. Given a matrix product state $Ψ$ defining a variational space, CBE identifies parts of the orthogonal space carrying significant weight in $HΨ$ and expands bonds to include only these. CBE-DMRG uses no mixing parameters and is fully variational. Using CBE-DMRG, we show that the Kondo-Heisenberg model on a width 4 cylinder features two distinct phases differing in their Fermi surface volumes.

description: We report a comparative study of the specific heat, electrical resistivity and thermal conductivity of the quasi-two-dimensional purple bronzes Na$_{0.9}$Mo$_6$O$_{17}$ and K$_{0.9}$Mo$_6$O$_{17}$, with special emphasis on the behavior near their respective charge-density-wave transition temperatures $T_P$. The contrasting behavior of both the transport and the thermodynamic properties near $T_P$ is argued to arise predominantly from the different levels of intrinsic disorder in the two systems. A significant proportion of the enhancement of the thermal conductivity above $T_P$ in Na$_{0.9}$Mo$_6$O$_{17}$, and to a lesser extent in K$_{0.9}$Mo$_6$O$_{17}$, is attributed to the emergence of phason excitations.

description: Wartime and veterans' homes, Canada's first standardized tract housing, were studied in order to identify and describe residents' adaptations since the original construction was completed (1941-1952). The subdivisions studied ranged from 150 to 350 units, and were located in Vancouver, British Columbia; Calgary, Alberta; Ajax, Ontario; Quebec City, Quebec; Fredericton, New Brunswick; and Halifax, Nova Scotia. These locations were chosen to represent characteristic changes related to Canada's major regions. A survey of thirty families in the Renfrew district of Calgary, Alberta was done to discover types, sequence, and frequency of adaptations. The relationship between demographic changes and housing changes was also investigated. Photography and observation, supplemented by archival material and interviews, were used to record changes to the original three standard unit types. Pertinent sociological and psychological studies relating to adaptation are drawn upon. This research found that minimum-standard small houses which were detached, surrounded by buildable land, and owned or controlled by residents, were continually adapted to accord with owners' needs and economic possibilities. Standardized house plans allowed residents to share ideas and skills needed to make adaptations. Physical and social conditions of adjacent areas influenced the type and amount of change. Stably-employed manual workers, and rural migrants to the city, who possessed the skills to make the adaptations themselves, were found to be satisfied with small incremental changes. The 300 dwelling units contained a population sufficient to foster development of shared community facilities, which increased opportunities for social participation outside the small homes. Therefore, residents were satisfied with more limited private spaces, as public spaces compensated for any lack by offering alternative places for childrens' and adults' activities. The evolution of a socioeconomically homogeneous working-class population resulted in shared values concerning family and neighbourhood standards, which encouraged permanent commitments to the adaptation and improvement of both the houses and the community.

 J.R.I. Wood et al. 24854, 25193, 25841 and 26081 (LPB, K) are apparently the first Bolivian records for this species representing a significant range extension beyond the previously known distribution in central and eastern Brazil (Barneby 1991: 129 MAP 9). Collected in three disparate localities in Provs. Angel Sandoval and Chiquitos, Santa Cruz, potentially widespread in eastern Bolivia, and apparently becoming more frequent following disturbance along the line of the newly constructed road from Santa Cruz to Brazil (Wood 2011). This material is a good match for M. acutistipula, although J.R.I. Wood et al. 25193 and 26081 (both from Quimome) have leaves with fewer (14–19 as opposed to 20–31) pairs of leaflets per pinna than typical material. In Bolivia this species occurs locally around rock platforms (known locally as “lajas”) and in similar places on roadsides.

description: Large-scale quantum-correlated networks could transform technologies ranging from communications and cryptography to computation, metrology, and simulation of novel materials. Critical to achieving such quantum enhancements is distributing high-quality entanglement between distant nodes. This is made possible in the unavoidable presence of decoherence by entanglement distillation. However, current versions of this protocol are prohibitively costly in terms of resources. We introduce a new scheme for continuous-variable entanglement distillation that requires only linear temporal and constant physical or spatial resources, both of which are exponential improvements over existing protocols. Our scheme uses a fixed module - an entanglement distillery - comprising only four quantum memories of at most 50 % storage efficiency and allowing a feasible experimental implementation. Tangible quantum advantages are obtained by using non-ideal quantum memories outside their conventional role of storage. By creating, storing and processing information in the same physical space, the scheme establishes a potentially valuable technique for designing stable, scalable protocols across different quantum technologies.

EVALUATION OFALTERNATIVE TRACK ALIGNMENTS ON WHOLE LIFE COST OF LOT 11 SECTION OF THE AWASH-WELDIYA RAILWAY LINE
Creators: name: Abebe, Muna
Publisher: name: Zenodo
Year: 2015

description: Geometric design is an essential and major component in the design development of railway projects. Geometric alignments (horizontal and vertical) affect project cost and safety significantly keeping other factors constant. The effect of track alignment on cost of awash-weldiya railway project in particular to Lot-11 stretch is evaluated in this thesis. Three different horizontal and vertical alignments are designed and their respective costs computed and compared. In the design process, topographic data is generated from 30m Resolution Digital Elevation Model using Global Mapper software. Horizontal and vertical alignments are designed using widely applicable Bentley Rail Track (BRT) software. In this thesis, Ethiopian Railways Corporation manual is used as governing rail standard. Basic techniques are applied for economical and safe design of the project. Generally, a minimum curve radius of 2000m and a maximum gradient of 2% is applied but a deviation from the standard is made in some parts due to topographic and other constraints. Accordingly, horizontal curves as low as 500m and gradient as high as 2.5% have been used in some places where there is topography constraint

description: An experimental investigation was carried out into (a) the incidence and kind of overt verbalisation in the perfor­mance of "non-verbal" tasks, and, (b) the occurrence of "displacement behaviour" during the per- formance of these The importance of language in the solution of non-verbal tasks has been demonstrated on normal children. The present study is concerned with two different age groups of subnormal children. A series of tasks was presented to the subjects, their performance being recorded by audio-visual equipment. Subsequent analysis of the data showed that there were:- (1) statistically significant differences between the kinds of verbalisation - relevant and irrelevant. (2) no significant differences between the two age groups in their verbal behaviour, though certain trends were apparent in terms of task difficulty and kinds of verbalisation. (3) significant differences between the two age groups with respect to displacement behaviour during tasks of high difficulty. (4) significant differences in some of the measures of displace­ment behaviour between tasks of low and high difficulty. General explanations of the results are offered and discussed. explanations concern the type of analysis employed, the nature of the sample, the difficulty levels of the tasks, and the roles played by the types of verbalisation in problem-solving behaviour.

Learning, Social Intelligence and the Turing Test - why an "out-of-the-box" Turing Machine will not pass the Turing Test

description: The Turing Test (TT) checks for human intelligence, rather than any putative general intelligence. It involves repeated interaction requiring learning in the form of adaption to the human conversation partner. It is a macro-level post-hoc test in contrast to the definition of a Turing Machine (TM), which is a prior micro-level definition. This raises the question of whether learning is just another computational process, i.e. can be implemented as a TM. Here we argue that learning or adaption is fundamentally different from computation, though it does involve processes that can be seen as computations. To illustrate this difference we compare (a) designing a TM and (b) learning a TM, defining them for the purpose of the argument. We show that there is a well-defined sequence of problems which are not effectively designable but are learnable, in the form of the bounded halting problem. Some characteristics of human intelligence are reviewed including it's: interactive nature, learning abilities, imitative tendencies, linguistic ability and context-dependency. A story that explains some of these is the Social Intelligence Hypothesis. If this is broadly correct, this points to the necessity of a considerable period of acculturation (social learning in context) if an artificial intelligence is to pass the TT. Whilst it is always possible to 'compile' the results of learning into a TM, this would not be a designed TM and would not be able to continually adapt (pass future TTs). We conclude three things, namely that: a purely "designed" TM will never pass the TT; that there is no such thing as a general intelligence since it necessary involves learning; and that learning/adaption and computation should be clearly distinguished.

description: Maximum-likelihood exponent maps have been studied as a technique to increase the understanding and improve the fit of power-law exponents to experimental and numerical simulation data, especially when they exhibit both upper and lower cut-offs. The use of the technique is tested by analyzing seismological data, acoustic emission data and avalanches in numerical simulations of the 3D-Random Field Ising model. In the different examples we discuss the nature of the deviations observed in the exponent maps and some relevant conclusions are drawn for the physics behind each phenomenon.

 J.R.I. Wood et al. 18512 (LPB, K) is the first record of this species, and of subseries Pedunculosae (sect. Mimosa, ser. Mimosa) for Bolivia. Given the distribution of the ten known species of subseries Pedunculosae in campo habitats on hills of the Paraná and Paraguay basins, and of M. alleniana from campo and cerrado in Paraguay and Mato Grosso do Sul on the east side of the Rio Paraguay, this species and subseries could be expected to occur in Bolivia. However it is only known in Bolivia from a restricted area of very vulnerable cerrado near Santiago de Chiquitos. It was categorised as Endangered (EN) by Mamani et al. (2010) but this status should be reviewed and perhaps changed to Critically Endangered (CR) as much of its habitat had been cleared and sown with Brachiaria brizantha when revisited in 2013.

description: We study a discrete nonlinear Schrödinger lattice with a parabolic trapping potential. The model, describing, e.g., an array of repulsive Bose-Einstein condensate droplets confined in the wells of an optical lattice, is analytically and numerically investigated. Starting from the linear limit of the problem, we use global bifurcation theory to rigorously prove that - in the discrete regime - all linear states lead to nonlinear generalizations thereof, which assume the form of a chain of discrete dark solitons (as the density increases). The stability of the ensuing nonlinear states is studied and it is found that the ground state is stable, while the excited states feature a chain of stability/instability bands. We illustrate the mechanisms under which discreteness destabilizes the dark-soliton configurations, which become stable only inside the continuum regime. Continuation from the anti-continuum limit is also considered, and a rich bifurcation structure is revealed.

Reinstating the M31 X-ray system RX J0042.3+4115 as a black hole X-ray binary, and compelling evidence for an extended corona

description: The M31 X-ray source RX J0042.3+4115 was originally identified as a black hole binary because it displayed characteristic low state variability at conspicuously high luminosities; unfortunately, this variability was later found to be artificial. However, analysis of 84 Chandra ACIS observations, an HST ACS/WFC observation, and a 60 ks XMM-Newton observation has supplied new evidence that RX J0042.3+4115 is indeed a black hole binary. The brightest optical star within 3 sigma of the position of RX J0042.3+4115 had a F435W (~B) magnitude of 25.4+/-0.2; M_B > -0.4, hence we find a low mass donor likely. RX J0042.3+4115 was persistently bright over ~12 years. Spectral fits revealed characteristic black hole binary states: a low/hard state at 2.08+/-0.08 E+38 erg/s, and a steep power law state at 2.41+/-0.05 E+38 erg/s (0.3--10 keV). The high luminosity low state suggests a ~20 M_Sun primary; this is high, but within the range of known stellar black hole masses. The inner disk temperature during the steep power law state is 2.24$\pm$0.15 keV, high but strikingly similar to that of GRS 1915+105, the only known Galactic black hole binary with a low mass donor t o be persistently bright. Therefore RX J0042.3+4115 may be an analog for GRS 1915+105; however, other mechanisms may account for its behavior. We find compelling evidence for an extended corona during the steep power law state, because compact corona models where the seed photons for Comptonization are tied to the inner disc temperature are rejected.

A note on geometric theories of fields

Publisher: name: arXiv
Year: 2022
Subjects: subject: Logic (math.LO)
subject: FOS: Mathematics

description: Let $T$ be a complete theory of fields, possibly with extra structure. Suppose that model-theoretic algebraic closure agrees with field-theoretic algebraic closure, or more generally that model-theoretic algebraic closure has the exchange property. Then $T$ has uniform finiteness, or equivalently, it eliminates the quantifier $\exists^\infty$. It follows that very slim fields in the sense of Junker and Koenigsmann are the same thing as geometric fields in the sense of Hrushovski and Pillay. Modulo some fine print, these two concepts are also equivalent to algebraically bounded fields in the sense of van den Dries. From the proof, one gets a one-cardinal theorem for geometric theories of fields: any infinite definable set has the same cardinality as the field. We investigate whether this extends to interpretable sets. We show that positive dimensional interpretable sets must have the same cardinality as the field, but zero-dimensional interpretable sets can have smaller cardinality. As an application, we show that any geometric theory of fields has an uncountable model with only countably many finite algebraic extensions.

description: Model predictions of the amount of the radioisotope 26Al produced in hydrogen-burning environments require reliable estimates of the thermonuclear rates for the 26gAl(p,γ)27Si and 26mAl(p,γ)27Si reactions. These rates depend upon the spectroscopic properties of states in 27Si within about 1 MeV of the 26gAl+p threshold (Sp = 7463 keV). We have studied the 28Si(3He,α)27Si reaction at 25 MeV using a high-resolution quadrupole-dipole-dipole-dipole magnetic spectrograph. For the first time with a transfer reaction, we have constrained Jπ values for states in 27Si over Ex = 7.0 - 8.1 MeV through angular distribution measurements. Aside from a few important cases, we generally confirm the energies and spin-parity assignments reported in a recent γ-ray spectroscopy study. The magnitudes of neutron spectroscopic factors determined from shell-model calculations are in reasonable agreement with our experimental values extracted using this reaction.

description: 6. * Mimosa bimucronata (DC.) Kuntze var. adenocarpa Hassler
 This var. was previously considered endemic to NE Paraguay (Barneby 1991). J.R.I. Wood et al. 24489 (LPB, K) is apparently the first record of this taxon for Bolivia, but perhaps to be expected, as previously known from the middle Paraguay river in Mato Grosso do Sul and NE Paraguay. Close to M. hexandra but consistently larger leafleted, narrower podded and 4- (as opposed to 3-) merous.

description: We report the use of a silicon nanowire mechanical oscillator as a low-temperature nuclear magnetic resonance force sensor to detect the statistical polarization of 1H spins in polystyrene. Under operating conditions, the nanowire experienced negligible surface-induced dissipation and exhibited a nearly thermally-limited force noise of 1.9 aN^2/Hz in the measurement quadrature. In order to couple the 1H spins to the nanowire oscillator, we have developed a new magnetic resonance force detection protocol which utilizes a nanoscale current-carrying wire to produce large time-dependent magnetic field gradients as well as the rf magnetic field.

Statistical properties of the dark matter haloes of dwarf galaxies and correlations with the environment

description: According to the now strongly supported concordance $Λ$CDM model, galaxies may be grossly described as a luminous component embedded in a dark matter halo. The density profile of these mass dominating haloes may be determined by N - body simulations which mimic the evolution of the tiny initial density perturbations during the process leading to the structures we observe today. Unfortunately, when the effect of baryons is taken into account, the situation gets much more complicated due to the difficulties in simulating their physics. As a consequence, a definitive prediction of how dark matter haloes should presently look like is still missing. We revisit here this issue from an observational point of view devoting our attention to dwarf galaxies. Being likely dark matter dominated, these systems are ideal candidates to investigate the present day halo density profiles and check whether dark matter related quantities correlate with the stellar ones or the environment. By fitting a large sample of well measured rotation curves, we infer constraints on both halo structural parameters (such as the logarithmic slope of the density profile and its concentration) and derived quantities (e.g., the mass fraction and the Newtonian acceleration) which could then be used to constrain galaxy formation scenarios. Moreover, we investigate whether the halo properties correlates with the environment the galaxy lives in thus offering a new tool to deepen our understanding of galaxy formation.

description: We present a general relation between celestial correlation functions in $d$-dimensions and Witten diagrams in $\left(d+1\right)$-dimensional Euclidean anti-de Sitter (EAdS) space, to all orders in perturbation theory. Contact diagram processes are proportional to contact Witten diagrams, and particle exchanges can be recast as a continuum of particle exchanges in EAdS where the exchanged particles carrying unitary Principal Series representations of $SO\left(d+1,1\right)$. One can then try to import familiar EAdS techniques to study the properties of celestial correlators. In this work we use this relation to infer the analytic structure of the spectral density in the conformal partial wave expansion of celestial correlators which, at least perturbatively, should be a meromorphic function of the spectral parameter. We also discuss non-perturbative constraints from unitarity in Euclidean Conformal Field Theory, which requires positivity of the spectral density. This extends similar relations recently uncovered between boundary correlation functions in de Sitter space and Witten diagrams in EAdS, suggesting that EAdS could play a central role in efforts towards holography for all lambdas.

On almost distance-regular graphs

description: Distance-regular graphs are a key concept in Algebraic Combinatorics and have given rise to several generalizations, such as association schemes. Motivated by spectral and other algebraic characterizations of distance-regular graphs, we study `almost distance-regular graphs'. We use this name informally for graphs that share some regularity properties that are related to distance in the graph. For example, a known characterization of a distance-regular graph is the invariance of the number of walks of given length between vertices at a given distance, while a graph is called walk-regular if the number of closed walks of given length rooted at any given vertex is a constant. One of the concepts studied here is a generalization of both distance-regularity and walk-regularity called $m$-walk-regularity. Another studied concept is that of $m$-partial distance-regularity or, informally, distance-regularity up to distance $m$. Using eigenvalues of graphs and the predistance polynomials, we discuss and relate these and other concepts of almost distance-regularity, such as their common generalization of $(\ell,m)$-walk-regularity. We introduce the concepts of punctual distance-regularity and punctual walk-regularity as a fundament upon which almost distance-regular graphs are built. We provide examples that are mostly taken from the Foster census, a collection of symmetric cubic graphs. Two problems are posed that are related to the question of when almost distance-regular becomes whole distance-regular. We also give several characterizations of punctually distance-regular graphs that are generalizations of the spectral excess theorem.
Planning ride-pooling services with detour restrictions for spatially heterogeneous demand: A multi-zone queuing network approach

description: This study presents a multi-zone queuing network model for steady-state ride-pooling operations that serve heterogeneous demand, and then builds upon this model to optimize the design of ride-pooling services. Spatial heterogeneity is addressed by partitioning the study region into a set of relatively homogeneous zones, and a set of criteria are imposed to avoid significant detours among matched passengers. A generalized multi-zone queuing network model is then developed to describe how vehicles' states transition within each zone and across neighboring zones, and how passengers are served by idle or partially occupied vehicles. A large system of equations is constructed based on the queuing network model to analytically evaluate steady-state system performance. Then, we formulate a constrained nonlinear program to optimize the design of ride-pooling services, such as zone-level vehicle deployment, vehicle routing paths, and vehicle rebalancing operations. A customized solution approach is also proposed to decompose and solve the optimization problem. The proposed model and solution approach are applied to a hypothetical case and a real-world Chicago case study, so as to demonstrate their applicability and to draw insights. Agent-based simulations are also used to corroborate results from the proposed analytical model. These numerical examples not only reveal interesting insights on how ride-pooling services serve heterogeneous demand, but also highlight the importance of addressing demand heterogeneity when designing ride-pooling services.

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: We present a theoretical approach to describing the Mott transition of electrons on a two dimensional lattice that begins with the low energy effective theory of the Fermi liquid. The approach to the Mott transition must be characterized by the suppression of density and current fluctuations which correspond to specific shape deformations of the Fermi surface. We explore the nature of the Mott insulator and the corresponding Mott transition when these shape fluctuations of the Fermi surface are suppressed without making any a prior assumptions about other Fermi surface shape fluctuations. Building on insights from the theory of the Mott transition of bosons, we implement this suppression by identifying and condensing vortex degrees of freedom in the phase of the low energy electron operator. We show that the resulting Mott insulator is a quantum spin liquid with a spinon fermi surface coupled to a U(1) gauge field which is usually described within a slave particle formulation. Our approach thus provides a coarse-grained treatment of the Mott transition and the proximate spin liquid that is nevertheless equivalent to the standard slave particle construction. This alternate point of view provides further insight into the novel physics of the Mott transition and the spin liquid state that is potentially useful. We describe a generalization that suppresses spin anti-symmetric fluctuations of the Fermi surface that leads to a spin-gapped charge metal previously also discussed in terms of slave particle constructions.

description: We study the dynamics of dark-bright solitons in binary mixtures of Bose gases at finite temperature using a system of two coupled dissipative Gross-Pitaevskii equations. We develop a perturbation theory for the two-component system to derive an equation of motion for the soliton centers and identify different temperature-dependent damping regimes. We show that the effect of the bright ("filling") soliton component is to partially stabilize "bare" dark solitons against temperature-induced dissipation, thus providing longer lifetimes. We also study analytically thermal effects on dark-bright soliton "molecules" (i.e., two in- and out-of-phase dark-bright solitons), showing that they undergo expanding oscillations while interacting. Our analytical findings are in good agreement with results obtained via a Bogoliubov-de Gennes analysis and direct numerical simulations.
