description: Despite studies related to big data in construction is growing, most of them have focused more on data application and less on the social element of the big data technology (e.g. data culture). This study aims to explore the key elements of data culture practices, towards providing a deeper insight into how they could drive digital competitiveness in the industry. A total of 136 papers related to big data in construction published in peer-reviewed journals were reviewed and analysed using the well-established systematic literature review (SLR) methodology. The findings indicate that four key drivers of data: data analytics, data literacy, data democratization and data leadership are critical for an organization’s competitiveness in a digital environment. A framework for data driven culture is proposed consisting of five elements: culture of production, culture of use, cultivation of data, datafication and data infrastructure. As cultural shifts are complicated endeavors, exploring the key elements on what it takes to drive the data culture in construction is necessary for the development of an effective digital ecosystem of the organization. This study extends the digital literature in the construction context by providing deeper insights into the conceptualization of data driven culture.

Ground-State Magnetization for Interacting Fermions in a Disordered Potential : Kinetic Energy, Exchange Interaction and Off-Diagonal Fluctuations

subject: FOS: Physical sciences

description: We study a model of interacting fermions in a disordered potential, which is assumed to generate uniformly fluctuating interaction matrix elements. We show that the ground state magnetization is systematically decreased by off-diagonal fluctuations of the interaction matrix elements. This effect is neglected in the Stoner picture of itinerant ferromagnetism in which the ground-state magnetization is simply determined by the balance between ferromagnetic exchange and kinetic energy, and increasing the interaction strength always favors ferromagnetism. The physical origin of the demagnetizing effect of interaction fluctuations is the larger number of final states available for interaction-induced scattering in the lower spin sectors of the Hilbert space. We analyze the energetic role played by these fluctuations in the limits of small and large interaction $U$. In the small $U$ limit we do second-order perturbation theory and identify explicitly transitions which are allowed for minimal spin and forbidden for higher spin. These transitions then on average lower the energy of the minimal spin ground state with respect to higher spin. For large interactions $U$ we amplify on our earlier work [Ph. Jacquod and A.D. Stone, Phys. Rev. Lett. 84, 3938 (2000)] which showed that minimal spin is favored due to a larger broadening of the many-body density of states in the low-spin sectors. Numerical results are presented in both limits.

description: PRRs (pseudo-response regulators) genes play crucial roles in plant growth and development, stress response and other life activities. However, this gene family in cabbage (Brassica oleracea var. capitata L) has yet to be comprehensively studied. To fully understand the status of PRR in cabbage, ten BoPRR genes were extracted from the whole genome of cabbage through bioinformatics analysis, and their gene structure, protein conservative motifs, cis acting elements and collinearity relationships were identified and analysed. Quantitative real-time PCR (qRT-PCR) was used to explore the expression patterns of BoPRR genes in cabbage leaves under various abiotic stresses. Based on phylogenetic analysis, the ten BoPRR genes were divided into three branches, located on four chromosomes. In addition, many photoresponsive elements exist in the promoter region, and specific response elements with low temperature, drought and abscisic acid (ABA). In terms of gene expression patterns, all ten BoPRR genes were found to be expressed in cabbage leaves and showed response to abiotic stress. This study represents the first comprehensive examination of the PRR family in cabbage, providing a theoretical basis for further research on abiotic stress and offering a new gene resource for breeding stress-resistant varieties.

description: Groundwater quality in arid alluvial fan plains on Tibetan Plateau is deteriorating due to human activities, yet relevant health risks remain understudied. This study investigates 37 groundwater samples from a typical alluvial fan plain of Qaidam basin, to explore the spatial variability and genesis of groundwater chemistry and associated health risks in the arid alluvial fan plains on Tibetan Plateau. The groundwater is slightly alkaline, predominantly characterized by the hydrochemical facies of Cl-Mg·Ca and Cl-Na type. Groundwater NO3−, NO2−, and NH4+ exceed the acceptable drinking water limits by 18.92%, 40.52%, and 16.22%, respectively. Natural forces, including silicates and evaporites dissolution, and cation exchange, dominate the groundwater chemistry. Anthropogenic inputs elevate groundwater nitrate levels (max 106.29 mg/L). The EWQI values range from 13.72 to 265.52, and near 84% of groundwater samples are suitable for domestic drinking. Non-carcinogenic health risk assessment on nitrogen is performed considering deterministic and probabilistic perspectives. All populations are facing health risks exposing to nitrogen-polluted groundwater, with the infants being the highest, followed by children, females, and males, and the risks are mainly caused by nitrate. Mitigation measures are urgently needed. This study could contribute to policy-making for groundwater security in the arid alluvial fan plains worldwide.

description: Objectives. Circulating osteocalcin (OC), a marker which is central in bone mineralization, may be involved in the atherosclerotic process and influence the risk of developing cardiovascular disease (CVD). We conducted a systematic review and meta-analysis of published observational evidence, to assess and quantify the associations of circulating OC (total, undercarboxylated, and carboxylated OC) with cardiovascular outcomes (clinical CVD endpoints and intermediate cardiovascular phenotypes). Design. Relevant studies were identified in a literature search of MEDLINE, EMBASE, and reference lists of relevant studies to March 2019. Mean differences and risk ratios with 95% CIs were aggregated using random-effects models. Results. Thirty-three observational studies (prospective and retrospective cohort, case-control, and cross-sectional) with data on 21,021 unique participants were eligible. The pooled risk ratio in a comparison of extreme fourths of total OC levels was 0.98 (95% CI 0.89, 1.08) for composite CVD. Circulating total OC levels were significantly lower in patients with cardiovascular conditions compared with those without these conditions −2.58 ng/ml (95% CI −3.85, −1.32; p < .001). Prospective and cross-sectional data showed significant inverse associations between total OC and traits such as aortic or coronary calcification, coronary atherosclerosis or calcification, carotid intima-media thickness, and plaque score. There was limited data on carboxylated and undercarboxylated OC, with no evidence of associations. Conclusion. Observational evidence generally supports inverse associations of circulating total OC with risk of atherosclerotic outcomes and CVD endpoints; however, the data were mostly based on cross-sectional evaluations. Large-scale prospective data are needed.
San Antonio’s Edwards Aquifer Protection Program: overview and analysis
Creators: name: Romero, Francine Sanders
Publisher: name: Texas Water Journal
Year: 2018

description: The City of San Antonio’s Edwards Aquifer Protection Program utilizes land and conservation easement acquisitions to protect the quality and quantity of Edwards Aquifer recharge. This review considers four key components of its viability: (1) establishing and sustaining public appreciation of the need for the policy, (2) choosing the appropriate policy mechanism to address the problem, (3) establishing clear justifications for prioritization of purchases that prevent mission drift, and (4) demonstrating the program’s impact and effectiveness. Overall, the analysis concludes that the program has been well adapted to the city’s need to protect the recharge and contributing zones beyond its regulatory jurisdiction. As such, it may serve as a significant model for other cities, particularly in Texas, where regulations may face legal and cultural resistance. The city has effectively educated the public on the value of this sales tax funded measure, even though some justification of its premises, such as inevitable development in western counties, remains subjective. A strong foundation is also evident, with a consistent focus on acquiring land that fits the original, narrow intent of the effort. An impediment to its continuation, however, may be the difficulty of presenting clear evidence of its success, a challenge for all policies designed to avert future harms to natural resources.

description: We derive constraints on the form of the renormalized stress tensor for states on Kerr space-time based on general physical principles: symmetry, the conservation equations, the trace anomaly and regularity on (sections of) the event horizon. This is then applied to the physical vacua of interest. We introduce the concept of past and future Boulware vacua and discuss the non-existence of a state empty at both scri- and scri+. By calculating the stress tensor for the Unruh vacuum at the event horizon and at infinity, we are able to check our earlier conditions. We also discuss the difficulties of defining a state equivalent to the Hartle-Hawking vacuum and comment on the properties of two candidates for this state.

description: Volume operators measuring the total volume of space in a loop quantum theory of cosmological models are constructed. In the case of models with rotational symmetry an investigation of the Higgs constraint imposed on the reduced connection variables is necessary, a complete solution of which is given for isotropic models; in this case the volume spectrum can be calculated explicitly. It is observed that the stronger the symmetry conditions are the smaller is the volume spectrum, which can be interpreted as level splitting due to broken symmetries. Some implications for quantum cosmology are presented.

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We introduce a simple two-dimensional spin model with short-range interactions which shows glassy behavior despite a Hamiltonian which is completely homogeneous and possesses no randomness. We solve exactly for both the static partition function of the model and the distribution of energy barriers, giving us the equilibration time-scales at low temperature. Simulations of instantaneous quenches and of annealing of the model are in good agreement with the analytic calculations. We also measure the two-time spin correlation as a function of waiting time, and show that the model has aging behavior consistent with the distribution of barrier heights. The model appears to have no sharp glass transition. Instead, it falls out of equilibrium at a temperature which decreases logarithmically as a function of the cooling time.

description: We present a systematic calculation of the cross section for the lepton-proton bremsstrahlung process l + p --> l' + p + gamma in chiral perturbation theory at next-to-leading order. This process corresponds to an undetected background signal for the proposed MUSE experiment at PSI. MUSE is designed to measure elastic scattering of low-energy electrons and muons off a proton target in order to extract a precise value of the proton's r.m.s. radius. We show that the commonly used peaking approximation, which is used to evaluate the radiative tail for the elastic cross section, is not applicable for muon-proton scattering at the low-energy MUSE kinematics. Furthermore, we point out a certain pathology with the standard chiral power counting scheme associated with electron scattering, whereby the next-to-next-to-leading order contribution from the pion loop diagrams is kinematically enhanced and numerically of the same magnitude as the next-to-leading order corrections. We correct a misprint in a commonly cited review article.

description: These proceedings summarize the LHCb measurements of charm- and beauty-hadron production in pPb collisions. The studies are made down to very low-\pt of the observed heavy-flavor hadrons using fully reconstructed decays. Nuclear matter effects are quantified via nuclear modification factors and forward-backward production ratios. A strong suppression is observed at positive rapidity (proton beam direction), while a modest or no suppression is seen for the backward rapidity (lead beam direction). The nuclear parton distributions of the lead nucleus is constrained down to Bjorken-$x\sim10^{-5}$, assuming it is the only nuclear effect for open heavy-flavor production. These data provide important inputs to understand the Quark-Gluon Plasma formed in heavy-nucleus collisions.

description: By high temperature series expansion, exact diagonalisation and temperature density-matrix renormalisation the magnetic susceptibility $χ(T)$ and the specific heat $C(T)$ of dimerised and frustrated $S=1/2$ chains are computed. All three methods yield reliable results, in particular for not too small temperatures or not too small gaps. The series expansion results are provided in the form of polynomials allowing very fast and convenient fits in data analysis using algebraic programmes. We discuss the difficulty to extract more than two coupling constants from the temperature dependence of $χ(T)$.

description: Image-based algorithmic software segmentation is an increasingly important topic in many medical fields. Algorithmic segmentation is used for medical three-dimensional visualization, diagnosis or treatment support, especially in complex medical cases. However, accessible medical databases are limited, and valid medical ground truth databases for the evaluation of algorithms are rare and usually comprise only a few images. Inaccuracy or invalidity of medical ground truth data and image-based artefacts also limit the creation of such databases, which is especially relevant for CT data sets of the maxillomandibular complex. This contribution provides a unique and accessible data set of the complete mandible, including 20 valid ground truth segmentation models originating from 10 CT scans from clinical practice without artefacts or faulty slices. From each CT scan, two 3D ground truth models were created by clinical experts through independent manual slice-by-slice segmentation, and the models were statistically compared to prove their validity. These data could be used to conduct serial image studies of the human mandible, evaluating segmentation algorithms and developing adequate image tools.

description: We propose a formulation of the term structure of interest rates in which the forward curve is seen as the deformation of a string. We derive the general condition that the partial differential equations governing the motion of such string must obey in order to account for the condition of absence of arbitrage opportunities. This condition takes a form similar to a fluctuation-dissipation theorem, albeit on the same quantity (the forward rate), linking the bias to the covariance of variation fluctuations. We provide the general structure of the models that obey this constraint in the framework of stochastic partial (possibly non-linear) differential equations. We derive the general solution for the pricing and hedging of interest rate derivatives within this framework, albeit for the linear case (we also provide in the appendix a simple and intuitive derivation of the standard European option problem). We also show how the ``string'' formulation simplifies into a standard N-factor model under a Galerkin approximation.

The reduction mechanism from (3+1) to (2+1) gravity is supported on a criterion in which the Weyl tensor components are required to vanish together with a dimensional reduction via an appropriate foliation. By using an adequate reduction mechanism from the Plebański-Carter[A] solution in (3+1) gravity, the (2+1) BTZ solution can be obtained.

Unlike resonant tunneling on Coulomb peaks, cotunneling in the valleys is sensitive to charging effects. We observe a larger magnetic field scale for the cotunneling (valley) fluctuations compared to the peaks, as well as an absence of "weak localization" (reduced conductance at B = 0) in valleys. Cotunneling fluctuations remain correlated over several valleys while peak conductance correlations decreases quickly.

description: We consider a system composed of a monodisperse charge-stabilized colloidal suspension in the presence of monovalent salt, separated from the pure electrolyte by a semipermeable membrane, which allows the crossing of solvent, counterions, and salt particles, but prevents the passage of polyions. The colloidal suspension, that is in a crystalline phase, is considered using a spherical Wigner-Seitz cell. After the Donnan equilibrium is achieved, there will be a difference in pressure between the two sides of the membrane. Using the functional density theory, we obtained the expression for the osmotic pressure as a function of the concentration of added salt, the colloidal volume fraction, and the size and charge of the colloidal particles. The results are compared with the experimental measurements for ordered polystyrene lattices of two different particle sizes over a range of ionic strengths and colloidal volume fractions.

description: hree forums were held between February 2015 and November 2016, bringing together Texas water experts from business, industry, government, academia, research, and the investment community in impartially facilitated sessions to determine ways to secure Texas’ water future through accelerating growth of infrastructure, technologies, research, education, and sustainable use. Consensus emerged after the first forum that Texas is approaching a water crisis reflecting matters of supply, allocation, and quality that demands immediate action to ensure water security and equitable access to this vital resource. Participant focus rested on new technology acceleration and investment, workforce education, research underway and desired by segments of the water sector, the water-energy-food nexus, outreach and public education, data management and access, water valuation, water security, and legal and regulatory frameworks. Participants also examined funding and partnership options for development of water treatment and supply infrastructure, water rights and allocation methods, aging infrastructure, and conservation, as well as the nearly ubiquitous fragmenting and compartmentalizing of just about everything having to do with water throughout the entire water sector. The forums generated and summarized a wealth of information that can be used by any party to make progress toward the goal of building a Texas water roadmap. This report summarizes the discussions and the path forward for securing Texas’ water resources.

description: Polycyclic aromatic hydrocarbons (PAHs), known as endocrine disruptors, may be linked to obesity. This study examines the associations between four urinary PAH metabolites and the body mass index (BMI), waist-to-hip ratio (WHR), and waist-to-height ratio (WHtR) in children. Using the generalized linear model (GLM), restricted cubic spline (RCS), weighted quantile sum (WQS) regression, and Bayesian kernel machine regression (BKMR) analyses, the associations between urinary PAH metabolites and obesity indicators were revealed. A total of 1409 children (675 boys, 734 girls) with means age of 10.19 and 9.25 years, respectively, were enrolled. The study identified a significant association between the fourth quartile of 1-hydroxypyrene and elevated BMI in boys. Additionally, the third and fourth quartiles of 2-hydroxyfluorene, as well as the second quartile of 9-hydroxyphenanthrene were linked to increased BMI in boys. For girls, the upper two quartiles of 9-hydroxyphenanthrene were independently associated with higher BMI and WHtR. Although nonlinear associations were not significant using RCS, 9-hydroxyphenanthrene demonstrated a significant positive correlation with both BMI and WHtR among girls. PAH mixtures were positively correlated with BMI in both genders and with WHtR in girls, with 2-hydroxyfluorene and 9-hydroxyphenanthrene being particularly influential in obesity. Gender differences in PAHs’ obesogenic effects are observed.

description: Time-series analysis in terms of ordinal patterns is revisited by introducing a generalized permutation entropy $H_p(w,L)$, which depends on two different window lengths: $w$, implicitly defining the resolution of the underlying partition; $L$, playing the role of an embedding dimension, analogously to standard nonlinear time-series analysis. The $w$-dependence provides information on the structure of the corresponding invariant measure, while the $L$-dependence helps determining the Kolmogorov-Sinai entropy. We finally investigate the structure of the partition with the help of principal component analysis, finding that, upon increasing $w$, the single atoms become increasingly elongated.

description: The efficient market hypothesis has far-reaching implications for financial trading and market stability. Whether or not cryptocurrencies are informationally efficient has therefore been the subject of intense recent investigation. Here, we use permutation entropy and statistical complexity over sliding time-windows of price log returns to quantify the dynamic efficiency of more than four hundred cryptocurrencies. We consider that a cryptocurrency is efficient within a time-window when these two complexity measures are statistically indistinguishable from their values obtained on randomly shuffled data. We find that 37% of the cryptocurrencies in our study stay efficient over 80% of the time, whereas 20% are informationally efficient in less than 20% of the time. Our results also show that the efficiency is not correlated with the market capitalization of the cryptocurrencies. A dynamic analysis of informational efficiency over time reveals clustering patterns in which different cryptocurrencies with similar temporal patterns form four clusters, and moreover, younger currencies in each group appear poised to follow the trend of their 'elders'. The cryptocurrency market thus already shows notable adherence to the efficient market hypothesis, although data also reveals that the coming-of-age of digital currencies is in this regard still very much underway.

description: Particle swarm optimization (PSO) is a representative swarm intelligence algorithm, which has the drawback of being restricted by premature convergence. To make PSO less likely to be restricted by premature convergence and to enhance its exploration and exploitation ability, this article proposes a social spider inspired particle swarm optimization (SSI-PSO). Based on PSO, the proposed algorithm divides the swarm into subgroups to mimic different behaviours of a social spider colony. Particles are classified in each iteration and then a variety of search strategies is adopted. Specifically, dominant male particles aim to search the neighbourhood, while negative female particles tend to search in the opposite direction to enhance the diversity. Meanwhile, positive female particles and non-dominant male particles are designed to balance the potential impact. Various commonly used benchmark functions and truss structural designs are tested for comparison. The results indicate that the proposed SSI-PSO is effective and efficient.

description: Dispersion interactions are long-range interactions between neutral ground-state atoms or molecules, or polarizable bodies in general, due to their common interaction with the quantum electromagnetic field. They arise from the exchange of virtual photons between the atoms, and, in the case of three or more atoms, are not additive. In this review, after having introduced the relevant coupling schemes and effective Hamiltonians, as well as properties of the vacuum fluctuations, we~outline the main properties of dispersion interactions, both in the nonretarded (van der Waals) and retarded (Casimir--Polder) regime. We then discuss their deep relation with the existence of the vacuum fluctuations of the electromagnetic field and vacuum energy. We describe some transparent physical models of two- and three-body dispersion interactions, based on dressed vacuum field energy densities and spatial field correlations, which stress their deep connection with vacuum fluctuations and vacuum energy. These models give a clear insight of the physical origin of dispersion interactions, and also provide useful computational tools for their evaluation. We show that this aspect is particularly relevant in more complicated situations, for example when macroscopic boundaries are present. We also review recent results on dispersion interactions for atoms moving with noninertial motions and the strict relation with the Unruh effect, and on resonance interactions between entangled identical atoms in uniformly accelerated motion.

description: A superconducting substrate is not able to shrink drastically domains in a ferromagnetic film, contrary to the prediction of Bulaevskii and Chudnovsky [Phys. Rev. B, 63, issue1 (2001)]. This is shown on the basis of the exact solution for the stripe domain structure.

description: A single-shot characterization of the temporal contrast of a petawatt laser pulse with a high dynamic-range, is important not only for improving conditions of the petawatt laser facility itself, but also for various high-intensity laser physics experiments, which is still a difficult problem. In this study, a new idea for improving the dynamic-range of a single-shot temporal contrast measurement using novel temporal contrast reduction techniques is proposed. The proof-of-principle experiments applying single stage of pulse stretching, anti-saturated absorption, or optical Kerr effect successfully reduce the temporal contrast by approximately one order of magnitude. Combining with the SRSI-ETE method, its dynamic-range characterization capability is improved by approximately one order of magnitude to approximately 109. It is expected that a higher dynamic-range temporal contrast can be characterized using cascaded temporal contrast reduction processes.

description: Though many new remote sensing technologies have been introduced to analyze forests, regional-scale species-level mapping products are still rare, especially in large mountainous areas. Tree species abundance, low spectral separability among species and huge computing demand are hindrances for obtaining an accurate stand tree species map. This study addressed these problems by synergizing regionalization, multiple feature fusion, and model fusion and proposed a new machine learning workflow. The whole area, i.e. Yunnan province in China (approximately 390,000 km2), was firstly divided into 8 distinct floristic regions according to the distributions and phylogenetic relationships of native tree species. Thereafter, with Google Earth Engine (GEE) platform, multiple data sets, including Sentinel-2 imagery, SRTM DEM, and WorldClim bioclimatic, were collected to construct a high-dimensional feature pool for each region. Thirdly, the maximum entropy model （MaxEnt）, generally used for predicting ecological niche, and three classifiers, i.e. Random Forest (RF), Support Vector Machines (SVM), and Extreme Gradient Boosting (XGBoost), were used to pre-classify environmental and remote sensing data, respectively. After that, two types of decision fusion strategies, parallel and serial ensembles, were applied to fuse pre-classification probability maps for each sub-region. Finally, the spatial distribution of 19 forest stand species over the whole Yunnan Province was obtained by mosaicking the best classification results from 8 sub-regions. Our method achieves an overall accuracy of 72.18% on the entire validation dataset. The decision fusion models significantly improve the classification accuracy, with the eight partitioned best fusion models improving the accuracy by 7.33%–25.39% on average compared to base classifiers. This study demonstrates that the spatial partitioning strategy and the decision fusion integrating a proper machine learning algorithm and ecological niche model can significantly improve the classification accuracy of forest stand species in montane forests.

description: The geometrical and quantum mechanical basis for Davies' and Unruh's acceleration temperature is traced to a type of quantum mechanical (``achronal'') spin. Its existence and definition are based on pairs of causally disjoint accelerated frames. For bosons the expected spin vector of monochromatic particles is given by the ``Planckian power'' and the ``r.m.s. thermal fluctuation'' spectra. Under spacetime translation the spin direction precesses around that ``Planckian'' vector. By exhibiting the conserved achronal spin four-current, we extend the identification of achronal spin from single quanta to multiparticle systems. Total achronal spin conservation is also shown to hold, even in the presence of quadratic interactions.

description: Zhang recently conjectured an approximate SO(5) symmetry relating antiferromagnetic and superconducting states in high-T_c cuprates. Here, an exact SO(5) symmetry is implemented in a generalized Hubbard model (with long-range interactions) on a lattice.
