description: We study the problem of the instability of inhomogeneous radiation universes in quadratic lagrangian theories of gravity written as a system of evolution equations with constraints. We construct formal series expansions and show that the resulting solutions have a smaller number of arbitrary functions than that required in a general solution. These results continue to hold for more general polynomial extensions of general relativity.

description: We propose that the optomechanical systems can be potential platforms to implement the Fröhlich condensate of phonons. We consider a one-dimensional array of membranes coupled to the cavity field via a quadratic interaction, and the cavity is pumped by an external laser. Analytical and numerical results predict that the high phonon occupancy of the lowest or highest mechanical mode is achievable depending on the detuning of the driving laser, the optomechnical strength, and the temperature. The decoherence of the Fröhlich condensate can be largely suppressed by the large number of membranes. Our results shed light on narrow-linewidth phonon laser, energy conversion/transfer, and efficient multimode cooling.

description: The three-wave mixing processes in a second-order nonlinear medium can be used for imaging protocols, in which an object field is injected into the nonlinear medium together with a reference field and an image field is generated. When the reference field is chaotic, the image field is also chaotic and does not carry any information about the object. We show that a clear image of the object be extracted from the chaotic image field by measuring the spatial intensity correlations between this field and one Fourier component of the reference. We experimentally verify this imaging protocol in the case of frequency downconversion.

description: Nuclear structure of 7Be, 8B and 7,8Li is studied within the ab initio no-core shell model (NCSM). Starting from the high-precision CD-Bonn 2000 nucleon-nucleon (NN) interaction, wave functions of 7Be and 8B bound states are obtained in basis spaces up to 10 hbar Omega and used to calculate channel cluster form factors (overlap integrals) of the 8B ground state with 7Be+p. Due to the use of the harmonic oscillator (HO) basis, the overlap integrals have incorrect asymptotic properties. We fix this problem in two alternative ways. First, by a Woods-Saxon (WS) potential solution fit to the interior of the NCSM overlap integrals. Second, by a direct matching with the Whittaker function. The corrected overlap integrals are then used for the 7Be(p,gamma)8B S-factor calculation. We study the convergence of the S-factor with respect to the NCSM HO frequency and the model space size. Our S-factor results are in agreement with recent direct measurement data.

description: Designated to “stay” in time and to “contrast” time – the former referred to the chronological meaning, the latter to the meteorological one – the life of buildings sometimes addresses the relationship with their pre-existences through variations linked to time. The essay aims at unfolding this phenomenon in the architecture of Álvaro Siza Vieira, proving his special ability to control the metamorphoses of the built matter. Complementing critical research with the dialogue established with the Portuguese master, the analysis of the evolutive process of some of his works demonstrates how time – intended as “the other architect”, which overlaps and opposes its own action to the one carried out by the builder – does not seem to counteract the experience of Siza but rather enhances the embedding of architecture in the site.

Perspectives on Machine Learning-augmented Reynolds-averaged and Large Eddy Simulation Models of Turbulence
Creators: name: Duraisamy, Karthik
Publisher: name: arXiv
Year: 2020
Subjects: subject: Fluid Dynamics (physics.flu-dyn)
subject: FOS: Physical sciences

description: This work presents a review and perspectives on recent developments in the use of machine learning (ML) to augment Reynolds-averaged Navier--Stokes (RANS) and Large Eddy Simulation (LES) models of turbulent flows. Different approaches of applying supervised learning to represent unclosed terms, model discrepancies and sub-filter scales are discussed in the context of RANS and LES modeling. Particular emphasis is placed on the impact of the training procedure on the consistency of ML augmentations with the underlying physical model. Techniques to promote model-consistent training, and to avoid the requirement of full fields of direct numerical simulation data are detailed. This is followed by a discussion of physics-informed and mathematical considerations on the choice of the feature space, and imposition of constraints on the ML model. With a view towards developing generalizable ML-augmented RANS and LES models, outstanding challenges are discussed, and perspectives are provided. While the promise of ML-augmented turbulence modeling is clear, and successes have been demonstrated in isolated scenarios, a general consensus of this paper is that truly generalizable models require model-consistent training with careful characterization of underlying assumptions and imposition of physically and mathematically informed priors and constraints to account for the inevitable shortage of data relevant to predictions of interest. Thus, machine learning should be viewed as one tool in the turbulence modeler's toolkit. This modeling endeavor requires multi-disciplinary advances, and thus the target audience for this paper is the fluid mechanics community, as well as the computational science and machine learning communities.

description: In this paper we improve the existing order parameter for monopole condensation in gauge theory vacuum, making it gauge-invariant from scratch and free of the spurious infrared problems which plagued the old one. Computing the new parameter on the lattice will unambiguously detect weather dual superconductivity is the mechanism for color confinement. As a byproduct we relate confinement to the existence of a finite correlation length in the gauge-invariant correlator of chromo-electric field strengths.

description: Quantum stabilizer states over GF(m) can be represented as self-dual additive codes over GF(m^2). These codes can be represented as weighted graphs, and orbits of graphs under the generalized local complementation operation correspond to equivalence classes of codes. We have previously used this fact to classify self-dual additive codes over GF(4). In this paper we classify self-dual additive codes over GF(9), GF(16), and GF(25). Assuming that the classical MDS conjecture holds, we are able to classify all self-dual additive MDS codes over GF(9) by using an extension technique. We prove that the minimum distance of a self-dual additive code is related to the minimum vertex degree in the associated graph orbit. Circulant graph codes are introduced, and a computer search reveals that this set contains many strong codes. We show that some of these codes have highly regular graph representations.

Parameters estimation and strong gravitational lensing of nonsingular Kerr-Sen black holes

description: The recent time witnessed a surge of interest in strong gravitational lensing by black holes is due to the Event Horizon Telescope (EHT) results, which suggest comparing the black hole lensing in both general relativity and heterotic string theory. That may help us to assess the phenomenological differences between these models. Motivated by this, we consider gravitational lensing by the nonsingular Kerr-Sen black holes, which encompass Kerr black holes as a particular case, to calculate the light deflection coefficients $p$ and $q$ in strong-field limits, while the former increases with increasing parameters $k$ and charge $b$, later decrease. We also find a decrease in the light deflection angle $α_D$, angular position $θ_{\infty}$ decreases more slowly and impact parameter for photon orbits $u_{m}$ more quickly, but angular separation $s$ increases more rapidly with parameters $b$ and $k$. We compare our results with those for Kerr black holes, and also the formalism is applied to discuss the astrophysical consequences in the case of the supermassive black holes NGC 4649, NGC 1332, Sgr A* and M87*. In turn, we also investigate the shadows of the nonsingular Kerr-Sen black holes and show that they are smaller and more distorted than the corresponding Kerr black holes and nonsingular Kerr black holes shadows. The inferred circularity deviation $ΔC\leq 0.10$, for the M87* black hole shadow, put constraints on the nonsingular Kerr-Sen black hole parameters ($a, k$) and ($a, b$). The maximum shadow angular diameter for $b=0.30M$ and $k=0.30M$ are, respectively, $θ_d=35.3461\,μ$as and $θ_d=35.3355\,μ$as. We also estimate the parameters associated with nonsingular Kerr-Sen black holes using the shadow observables.

description: When honey bees transport pollen across citrus orchards they can increase the number of seeds in varieties that remain seedless otherwise. An increase in seeds diminishes the market value of the fruit creating an externality between seedless growers and beekeepers. This paper investigates the efficiency of different policy resolution of this externality including a range of regulated spatial segregations of beekeeping and seedless farming with or without financial compensations. We develop a spatial model of honey foraging behavior to quantify the efficiencies and redistributions of different policies that may be used to correct this market failure. Some of these policies have been implemented others are being currently discussed in policy debates in the California citrus belt. This paper illustrates that quantifying biophysical processes that create externalities is a necessary step towards evaluating the economics efficiency of alternative solutions.

description: Dairy managers today are faced with the decision to either raise their own replacements on the dairy farm or send heifers to a custom heifer grower. The largest potential challenge of contracting out the heifer raising enterprise revolves around the potential for a moral hazard problem because of hidden action on the part of the custom heifer grower. A principal-agent framework was used to elicit contract terms which provide incentives for the custom heifer grower to perform accelerated growth without heifers becoming over-conditioned. In order to provide incentives to custom growers, heifers returned to the dairy farm should be compared in performance to other heifers of similar age. We solve for the price paid per pound of gain, price paid for inch of wither height above the average heifer on the operation, deduction per unit of body condition score over or under ideal body condition score, and percent of the value of milk production above the average milk production by herd peers. Such comparisons are similar to tournament contracts, such as those used in raising poultry or swine.

description: Signs often appear on the surfaces of the urban fabric, some due to the passage of time, others to the constant alterations of man. This essay reflects on the role the reuse of elements assumes in contemporary architecture and on the contribution this practice can offer to a design suited to the built environment. The analysis will consider the environment both from an ecological perspective and as a “place” constantly modified by nature and man. The study of the reasons for reuse in the past and present, discussing them from the point of view of contemporary professionals, allows an original interpretation of the relationship between the circularity of time and the circularity of material flows with a view to preserving resources.

description: The analysis of the “living space” and its peculiar morpho-architectural connotations in an uncertain and ever evolving reality implies the use of new paradigms linked to concepts such as temporariness, flexibility, disassembly, recyclability, adaptability and reversibility. Demographic transformations, in addition to ever-changing habits, rhythms and lifestyle, lead the present study to investigate time as a design paradigm of an evolutionary home, seeking a criterion and a methodological approach that is capable of thinking about modifiable spaces, which are not strictly predetermined but open to new ways of expressing the users’ need for customisation.

description: This paper examines whether it makes sense to consider Sutton's "bounds" approach as a candidate theory for explaining the recent evolution of market structure in the biotechnology sector, and to speculate whether market structure will change if the industry begins to introduce second-generation GM products that are of more direct benefit to consumers. A key result is that the market structure is bounded in the presence of endogenous sunk costs, implying care should be taken when inferring any correlation between R&D expenditure and seller concentration in the biotechnology sector.
Including climate change time-dimensions in bioclimatic design
Creators: name: Chiesa, Giacomo
name: Von Hardenberg, Jost
Publisher: name: TECHNE - Journal of Technology for Architecture and Environment
Year: 2020

description: Traditionally, green design considers climate as a fixed property of a specific place. Nevertheless, recent changes demonstrate that this vision has to be reversed, considering climate a time-dependent parameter. This paper hybridises climatology and bioclimatic design underlining, thanks to the usage of a very recent high resolution climate reanalysis database (ERA5-Land), the impact that climate changes have on short-term periods, adopting well known building climate-related indicators. European maps are drawn considering degree-days variations (from 1981-95 to 2004-18), while typical mean 24-hour monthly days and bioclimatic charts are adopted for a limited number of locations. Results support the need to adopt climate data time variations during design phases.

Year: 2020

description: Time acts as a fundamental variable of urban transformation. In fact, changing needs can make an architecture or a technological unit obsolete over time. Precisely, this unexpected deficiency in performance can no longer be interpreted as a limitation but rather as potential to update the architecture itself. This paper fits into this framework and investigates both the potential and limitations of architecture considered an upgradeable system in which time, and the need for changes, become a variable of transformation. By analysing a case study and possible updating strategies relative to a renewed demand framework, the paper underlines the potential that modern architecture offers in terms of updating.

description: An Orthogonal Least Squares (OLS) based feature selection method is proposed for both binomial and multinomial classification. The novel Squared Orthogonal Correlation Coefficient (SOCC) is defined based on Error Reduction Ratio (ERR) in OLS and used as the feature ranking criterion. The equivalence between the canonical correlation coefficient, Fisher's criterion, and the sum of the SOCCs is revealed, which unveils the statistical implication of ERR in OLS for the first time. It is also shown that the OLS based feature selection method has speed advantages when applied for greedy search. The proposed method is comprehensively compared with the mutual information based feature selection methods and the embedded methods using both synthetic and real world datasets. The results show that the proposed method is always in the top 5 among the 12 candidate methods. Besides, the proposed method can be directly applied to continuous features without discretisation, which is another significant advantage over mutual information based methods.

description: Friction measurements were made with a skid trailer at 40 mph (18 m/s) on 1460 miles (2350 km) of rural, two-lane roads (US routes) in Kentucky. Maintenance sections or subsections were treated as test sections. Accident experience, friction measurements, traffic volumes, and other available data were obtained for each. Various expressions of wet-pavement accidents and pavement friction were related and analyzed. Averaging methods were used in developing trends and minimizing scatter. A moving average for progressively-ordered sets of ten test sections and test sections grouped by Skid Numbers and Peak Slip Numbers yielded more definite results. The expression of accident occurrence which correlated best with skid resistance and peak slip resistance was ratio of wet- to dry-pavement accidents. Accidents increased greatly as Skid Number decreased from about 40 and as Peak Slip Number decreased from about 71.
The time factor in the design of adaptive architectures

description: Architectures capable of dynamically interacting with the context and change aspects of their physicality are an interdisciplinary research field with many implications on living environments and on design itself. In this area, the designers’ attention is mainly focused on the temporal aspect, on the relationship with project, technology, and construction, framing the discussion on tools and design strategies for the dynamic management of variables, on the one hand, and on innovations affecting technologies and actors of the design process, on the other. In the field of adaptive architecture, the paper proposes a reinterpretation of the meaning of duration, explaining the structure and the key factors that characterise its application approach.

Decaying dark matter, the $H_0$ tension, and the lithium problem

description: It has long been known that the sharpened tension between the observed and inferred values of the Hubble constant $H_0$ can be alleviated if a fraction of dark matter particles of type $χ$ were produced non-thermally in association with photons $γ$ through the decays of a heavy and relatively long-lived state, viz. $X \to χ+ γ$. It was recently proposed that this model can also resolve the longstanding lithium problem if $M= 4$ MeV and $m = 0.04$ keV, where $M$ and $m$ are respectively the masses of $X$ and $χ$. We confront this proposal with experiment and demonstrate that cold dark matter decaying before recombination cannot resolve the $H_0$ problem. Moreover, we show that the best case scenario for alleviating the $H_0$ tension within the context of cold dark matter decaying before recombination arises when the particles decay exclusively into dark radiation, while leaving completely unmodified the production of light elements. To this end we calculate the general functional form describing the number of equivalent light neutrino species $ΔN_{eff}$ carried by $χ$. We show that to resolve the $H_0$ tension at the $1σ$ level a 55% correction in $m$ is needed and that the required $ΔN_{eff}$ is excluded at 95% CL by Planck data. We argue in favor of a more complex model of dynamical dark matter to relax the $H_0$ tension.

Characteristics of Traffic Streams on Rural, Multilane Highways

Year: 1976
Subjects: subject: Transportation Engineering

description: The purpose of this study was to develop a data base and interrelationships for traffic characteristics on rural, multilane highways. Primary emphasis was placed on factors influencing lane distribution. Other characteristics investigated were vehicle speeds, vehicle classifications, volumes, time distributions of flow, and noise emitted by vehicle type and weight. Most analyses were based on traffic characteristics data collected in the summer of 1973. Analyses of 1968 and 1975 traffic characteristics data were compared with 1973 data for the purpose of investigating unusual trends over the various time periods. The 1968 and 1973 surveys produced similar results; however, some changes were noted between 1973 and 1975. Much of the change was attributed to the "energy crisis" and the associated reduction in speed limit.  It was found that the addition of any variable other than hourly traffic volume, did not contribute significantly to the accuracy of predicting lane distribution of traffic. Lane distribution percentages of total traffic ranged from a 64-36 (shoulder lane - median lane) split on I 75 at the Grant County site in 1968 to a 90-10 split at the I 64 Rowan County site in 1973.  Graphical relationships and equations were developed from 1973 data which permit conversion from ADT's on rural, four-lane highways to lane distribution percentages and corresponding percentages of various vehicle types.  Average noise levels in 1973 ranged from 75.8 decibels for autos and pickups to 89.2 decibels for combination, five-axle trucks.  Average car speeds decreased by 8.3 mph (3.7 m/s) and average truck speeds decreased by 2.0 mph (0.9 m/s) between June 1973 and December 1975.

description: We investigate the dynamics of chaotic trajectories in simple yet physically important Hamiltonian systems with non-hierarchical borders between regular and chaotic regions with positive measures. We show that the stickiness to the border of the regular regions in systems with such a sharply divided phase space occurs through one-parameter families of marginally unstable periodic orbits and is characterized by an exponent γ= 2 for the asymptotic power-law decay of the distribution of recurrence times. Generic perturbations lead to systems with hierarchical phase space, where the stickiness is apparently enhanced due to the presence of infinitely many regular islands and Cantori. In this case, we show that the distribution of recurrence times can be composed of a sum of exponentials or a sum of power-laws, depending on the relative contribution of the primary and secondary structures of the hierarchy. Numerical verification of our main results are provided for area-preserving maps, mushroom billiards, and the newly defined magnetic mushroom billiards.

description: We investigate dispersion relation of Nambu-Goldstone modes in a dissipative system realized by the AdS/CFT correspondence. We employ the D3/D7 model which represents ${\cal N} = 4$ supersymmetric Yang-Mills theory coupled to ${\cal N = 2}$ flavor fields. If we consider massless quarks in the presence of an external magnetic field, the system exhibits the phase transition associated with the spontaneous symmetry breaking of the chiral symmetry. We find that the Nambu-Goldstone modes shows a diffusive behavior in the dispersion relation, which agrees with that found with the effective field theory approach. We also study a non-equilibrium steady state which has a constant current flow in the presence of an external electric field. In a non-equilibrium steady state, we find that the Nambu-Goldstone modes shows a linear dispersion in the real part of the frequency in addition to the diffusive behavior. Moreover, we analyze the linear dispersion of the Nambu-Goldstone modes in the hydrodynamic approximation. As a result, we find that the linear dispersion can be written as the analytic functions of quantities in the dual field theory. Our results imply that such a linear dispersion is a characteristic behavior of Nambu-Goldstone modes in a non-equilibrium steady state.

Photonic band mixing in linear chains of optically coupled micro-spheres
Creators: name: Deych, L.

Year: 2005
Subjects: subject: Optics (physics.optics)

description: The paper deals with optical excitations arising in a one-dimensional chain of identical spheres due optical coupling of whispering gallery modes (WGM). The band structure of these excitations depends significantly on the inter-mixing between WGMs characterized by different values of angular quantum number, $l$. We develop a general theory of the photonic band structure of these excitations taking these effects into account and applied it to several cases of recent experimental interest. In the case of bands originating from WQMs with the angular quantum number of the same parity, the calculated dispersion laws are in good qualitative agreement with recent experiment results. Bands resulting from hybridization of excitations resulting from whispering gallery modes with different parity of $l$ exhibits anomalous dispersion properties characterized by a gap in the allowed values of \emph{wave numbers} and divergence of group velocity.

description: Approximately 1,406,100 linear feet (428,579 m) of hot-sprayed thermoplastic stripe was applied to roadways in Louisville and Jefferson County in the summer of 1973. Visual observations of appearance, durability, and night visibility were conducted according to ASTM D 713-69, the standard method for conducting road service tests on traffic paint. Attempts to conduct photometer measurements of the thermoplastic striping were unsuccessful. Visual observations made during rainy, nighttime conditions were also unsuccessful because very little difference was noticeable among the various sections.  The evaluation showed that the thermoplastic stripes performed considerably better on bituminous concrete pavements than on portland cement concrete pavements. White thermoplastic stripes were generally better than yellow stripes, particularly on portland cement concrete surfaces.  No definite relationship was found between durability of thermoplastic striping and traffic volume for stripes applied to bituminous concrete pavements. The stripes, however, were less durable on the older pavements. On portland cement concrete pavements, the stripes were less durable on high volume roads and older pavements.  An economic analysis of the cost of thermoplastic and paint striping revealed that thermoplastic striping is more economical on the higher volume roads. Volumes required for thermoplastic striping to be more economical than paint striping ranged from 15,000 vehicles per day on a two-lane bituminous concrete pavement (white or yellow stripes) to 120,000 vehicles per day on a six-lane portland cement concrete pavement (yellow stripes). Volumes required for other highway types, pavement type, and line color are also presented.
Floquet generation of Second Order Topological Superconductor

description: We theoretically investigate the Floquet generation of second-order topological superconducting (SOTSC) phase, hosting Majorana corner modes (MCMs), considering a quantum spin Hall insulator (QSHI) with proximity induced superconducting $s$-wave pairing in it. Our dynamical prescription consists of the periodic kick in time-reversal symmetry breaking in-plane magnetic field and four-fold rotational symmetry breaking mass term while these Floquet MCMs are preserved by anti-unitary particle-hole symmetry. The first driving protocol always leads to four zero energy MCMs (i.e. one Majorana per corner) as a sign of a {\it{strong}} SOTSC phase. Interestingly, the second protocol can result in a {\it{weak}} SOTSC phase, harbouring eight zero energy MCMs (two Majorana states per corner), in addition to the {\it{strong}} SOTSC phase. We characterize the topological nature of these phases by Floquet quadrupolar moment and Floquet Wannier spectrum. We believe that relying on the recent experimental advancement in the driven systems and proximity induced superconductivity, our schemes may be possible to test in the future.

Acoustic Emission, Fatigue, and Crack Propagation
Creators: name: Hopwood, Theodore
Publisher: name: Kentucky Transportation Center, University of Kentucky
Year: 1976
Subjects: subject: Transportation Engineering

description: Acoustic emission was used in conjunction with tensile tests to evaluate the condition of structural steel specimens subject to various tensile fatigue lives. The results indicate that the acoustic emissions detected were the result of plastic deformation. There was no apparent relationship between fatigue history of the steel specimens and the amount of plastic deformation they can accommodate.  Further tests revealed that acoustic emission has the physical capability of detecting cracks on large structural steel members. This may prove beneficial for the comprehensive testing of steel bridges.
The suspended time of the interrupted process: beyond repression, a future for unfinished buildings

Year: 2020

description: The results of the interrupted building processes are ascribable to an anomalous category of built environment, which offers an important test bench for the technological design of architecture. In fact, the finalism focused on achieving the objectives and the linear vision of time are irrelevant when confronted by constructions, whose life cycle has never begun and which are irreducibly extraneous to both the present and the future. The bipolar phenomenon of unfinished buildings suggests a theoretical framework linked to the time variable, intended as a transformation factor and cornerstone of architectural design. Considering their diffusion and evolution, a future is foreseeable for the unfinished buildings, which is different to a certain kind of pretentious demonisation or exaltation.

Angular momentum anisotropy of Dirac carriers: A new twist in graphene

description: Dirac carriers in graphene are commonly characterized by a pseudospin degree of freedom, arising from the degeneracy of the two inequivalent sublattices. The inherent chirality of the quasiparticles leads to a topologically non-trivial band structure, where the in-plane component of sublattice spin and momentum are intertwined. Equivalently, sublattice imbalance is intimately connected with angular momentum, inducing a torque of opposite sign at each Dirac point. In this work we develop an intuitive picture that associates sublattice spin and winding number with angular momentum. We develop a microscopic perturbative model to obtain the finite angular momentum contributions along the main crystallographic directions. Our results can be employed to determine the angular dependence of the g-factor and of light absorption in honeycomb bipartite structures.
