description: Information and communication technologies are permeating all aspects of industrial and manufacturing systems, expediting the generation of large volumes of industrial data. This article surveys the recent literature on data management as it applies to networked industrial environments and identifies several open research challenges for the future. As a first step, we extract important data properties (volume, variety, traffic, criticality) and identify the corresponding data enabling technologies of diverse fundamental industrial use cases, based on practical applications. Secondly, we provide a detailed outline of recent industrial architectural designs with respect to their data management philosophy (data presence, data coordination, data computation) and the extent of their distributiveness. Then, we conduct a holistic survey of the recent literature from which we derive a taxonomy of the latest advances on industrial data enabling technologies and data centric services, spanning all the way from the field level deep in the physical deployments, up to the cloud and applications level. Finally, motivated by the rich conclusions of this critical analysis, we identify interesting open challenges for future research. The concepts presented in this article thematically cover the largest part of the industrial automation pyramid layers. Our approach is multidisciplinary, as the selected publications were drawn from two fields; the communications, networking and computation field as well as the industrial, manufacturing and automation field. The article can help the readers to deeply understand how data management is currently applied in networked industrial environments, and select interesting open research opportunities to pursue.

description: There are several classes of homogeneous Fermi-systems which are characterized by the topology of the energy spectrum of fermionic quasiparticles: (1) Gapless systems with a Fermi-surface; (2) Systems with a gap in their spectrum; (3) Gapless systems with topologically stable point nodes (Fermi points); and (4) Gapless systems with topologically unstable lines of nodes (Fermi lines). Superfluid 3He-A and electroweak vacuum belong to the universality Class (3). The fermionic quasiparticles (particles) in this class are chiral: they are left-handed or right-handed. The collective bosonic modes of systems of Class (3) are the effective gauge and gravitational fields. The great advantage of superfluid 3He-A is that we can perform experiments using this condensed matter and thereby simulate many phenomena in high energy physics, including axial anomaly, baryoproduction, and magnetogenesis. 3He-A textures induce a nontrivial effective metrics of the space, where the free quasiparticles move along geodesics. With 3He-A one can simulate event horizons, Hawking radiation, rotating vacuum, etc. High-temperature superconductors are believed to belong to Class (4). They have gapless fermionic quasiparticles with a "relativistic" spectrum close to gap nodes, which allows application of ideas developed for superfluid 3He-A.

description: Palladin, a cytoskeletal protein with essential functions for stress fiber formation, is found in developing and mature tissues, including the kidney. To define its role in the kidney, we measured its expression in mouse kidney and found it co-localized with F-actin in smooth muscle cells of renal arterial vessels, mesangial cells, and podocytes but not in tubular epithelium. Using immunoelectron microscopy, we confirmed that palladin was present in podocytes. In cultured mouse podocytes, palladin co-localized with F-actin in dense regions of stress fibers, focal adhesions, cell-cell contacts and motile cell margins. Transfection with the N-terminal half of palladin targeted it to F-actin-containing structures in podocytes while the C-terminal half accumulated in the nucleus, a result also found for endogenous palladin in cultured cells after leptomycin B was used to block nuclear export. Green fluorescent protein (GFP)-tagged palladin was found in dynamic ring-like F-actin structures and ruffles in cultured podocytes after stimulation with epidermal growth factor. Inhibition of palladin expression by transfection of an antisense construct reduced the formation of ring-like structures. Photo-bleaching analysis showed that GFP-palladin turned over with a half-time of 10 s in focal adhesions and dense regions of stress fibers, suggesting that palladin is a dynamic scaffolding protein. Our study shows that palladin is expressed in podocytes and plays an important role in actin dynamics.

description: Reinforced concrete columns represented the main load bearing members of any type of structure and should be designed adequately since it supports beams and slabs and transfers the load to the foundation. The strength of columns is controlled by the strength of the material used (grade of concrete) and the (cross-section geometry). Plane self-compacted concrete is facing a weakness in cracking resistance, this leads to applying of steel fiber in the concrete mixes, but steel fiber reduced the SCC workability. The opposing effects are the subject of this investigation. This research investigates experimentally and analytically the influence of steel fiber with volume fraction (0, 1 and 2% by volume) on ultimate capacity and the deformation behavior of three types of (normal, high and ultra-high self-compacting concrete) with different compressive strength on reinforced concrete column of size (100*100*700mm) under concentric loading. Nine short reinforced concrete columns are examined and compared. These columns divided into three groups each group contains 3 columns with different steel fiber ratio. Experimental data for strength, deformation, and failure mode were obtained for each test. Properties of hardened SCC were investigated. To determine the workability, different test methods are adopted in this research such as slump flow, T50, and L-box. Results indicated that the properties of different SCC can be improved by the addition of steel fiber. The inclusion of steel fibers was an effective way to prevent spalling of the concrete cover, increase the ductility and increases strength. Finite element (ANSYS software program) is used for the analysis. The analytical results are in high-grade complying with the experimental data. The comparison shows that the ANSYS is capable of modeling and predicting the actual behavior of reinforced concrete column.

description: We studied coherent backscattering (CBS) of light from opal photonic crystals in air at different incident inclination angles, wavelengths and along various [hkl] directions inside the opals. Similar to previously obtained CBS cones from various random media, we found that when Bragg condition with the incident light beam is not met then the CBS cones from opals show a triangular line shape in excellent agreement with light diffusion theory. At Bragg condition, however, we observed a dramatic broadening of the opal CBS cones that depends on the incident angle and [hkl] direction. This broadening is explained as due to the light intensity decay in course of propagation along the Bragg direction {\em before the first} and {\em after the last} scattering events. We modified the CBS theory to incorporate the attenuation that results from the photonic band structure of the medium. Using the modified theory we extract from our CBS data the light mean free path and Bragg attenuation length at different [hkl]. Our study shows that CBS measurements are a unique experimental technique to explore photonic crystals with disorder, when other spectroscopical methods become ambiguous due to disorder-induced broadening.

description: This literature review examines the state of the art on two related research areas: on protective policies and on emotions related to politics as well as on political communication and policy-making. Both reviews deliver important insights into main debates in the respective strands: On protective policies, the analysis shows that the concept itself has not been used widely, whereas protection is mentioned repeatedly in articles related to specific policy areas, such as social protection, environmental protection or health protection. Hence, combing the insights from these different areas can lead to an enhanced understanding of the cross-cuttingness of protection, which will be further explored in PROTEMO. With regard to emotion in the realm of politics, scholars have extensively investigated the affective dimensions of political behaviour and political communication. However, with some exceptions, extensive empirical studies on the concrete role of emotion in the process of policy-making are missing from the academic literature. PROTEMO addresses this lack and thereby contributes to a more comprehensive understanding of policy-making in an era of multiple insecurities.Finally, drawing together the results of the two parts, the review yields several important insights about possible interlinkages, namely on the target groups of protection, the origin of protection, the assessment of the need of protection, providers of protection, policy instruments providing protection, drivers of protection and the time horizon related to protection. These insights can inform a theoretical conceptualization of protective policies as well as guide the development of hypotheses on how emotions affect the policy-making process on protective policies and vice versa.

description: A new phenomenon is observed experimentally in a heavily doped asymmetric quantum-size structure in a magnetic field parallel to the quantum-well layers - a transverse magnetoresistance which is asymmetric in the field (there can even be a change in sign) and is observed in the case that the structure has a built-in lateral electric field. A model of the effect is proposed. The observed asymmetry of the magnetoresistance is attributed to an additional current contribution that arises under nonequilibrium conditions and that is linear in the gradient of the electrochemical potential and proportional to the parameter characterizing the asymmetry of the spectrum with respect to the quasimomentum.

We obtain a generic form for the gravitational field equations and derive the hydrostatic equation for Earth's atmosphere for leading order terms $f(R,T) = R + 2χT.$ Based on the apparent accuracy of the 1976 U.S. Standard Atmosphere model, which varies no more than $10\%$ from observations, we find limits of $-1.6\times 10^{-13} \lesssim χ\lesssim 1.8\times 10^{-13}$.

description: The mixed phase of extremely type-II layered superconductors in perpendicular magnetic field is studied theoretically via the layered XY model with uniform frustration. A partial duality analysis is carried out in the weak-coupling limit. It consistently accounts for both intra-layer (pancake) and inter-layer (Josephson) vortex excitations. The main conclusion reached is that dislocations of the two-dimensional (2D) vortex lattices within layers drive a unique second-order melting transition at high perpendicular fields between a low-temperature superconducting phase that displays a Josephson effect and a high-temperature ``normal'' phase that displays no Josephson effect. The former state is best described by weakly coupled 2D vortex lattices, while the latter state is best characterized by a decoupled vortex liquid. It is further argued on the basis of the duality analysis that the second-order melting transition converts itself into a first-order one as the perpendicular field is lowered and approaches the dimensional cross-over scale. The resulting critical endpoint potentially accounts for the same phenomenon that is observed in the mixed phase of clean high-temperature superconductors.

Experimental and Analytical Study of Behavior of Ultra High Self Compacted Hollow Core Reinforced Concrete One-Way Slabs

Subjects: subject: 90599 Civil Engineering not elsewhere classified

description: Self-compacting concrete (SCC) can be classified as high-performance concrete. Its behavior does not demand to be vibrated to achieve full compaction. This proposes various privileges and advantages over conventional concrete. It is one of the most significant developments in concrete technology. Although it has distinguished performance, but it like normal concrete in signifying the brittle material with low tensile strength and poor fracture energy, accordingly, steel fibers can be combined to improve tensile strength, bending, shear, stiffness and fracture energy. This research presents experimental study to investigate the behavior of ultra-high strength steel fiber-self compacting concrete of hollow core one-way slabs with or without openings. It includes testing of seventeen reinforced concrete one-way hollow core slabs cast using ultra-high strength self-compacting concrete (HSSCC) with using steel fibers to evaluate their behavior and strength. All tested slabs have dimensions of (1000*500*50mm). The parameters considered are openings size, openings location, opening shape, reinforcement ratio (ρ), steel fiber volumetric ratio (Vf) and cores. The effect of these parameters on the behavior of the tested slabs included investigation of deflection, failure mode, and ultimate loads. Preliminary investigation tests were conducted to study the fresh and hardened properties of concrete. Results of the experimental test determine that increase in steel fiber content leads to an increase in the failure load and maximum deflection. In addition, a finite element analysis using ANSYS program was appropriated to model the certified slabs and a reasonable compatibility was attained between the finite element analysis and the test results.

description: What is the relationship between gender norms, agency, and agricultural innovation? How might we undertake and what can we learn from a comparative approach to this question? GENNOVATE—a comparative and collaborative research project—addresses these questions using contextually embedded qualitative analyses that also allow for comparison and extrapolation of patterns across multiple locations. This paper provides an overview of the conceptual approach and the methodological strategy that informed GENNOVATE’s twin objectives and research design. The conceptual framework underlying this original research initiative is introduced and the challenges and opportunities faced when combining inductive and deductive analytic approaches are discussed. The empirical and methodological issues are explored and the broad relevance of GENNOVATE’s research approach beyond the field of agricultural development is reflected upon.

Aperiodic space-inhomogeneous quantum walks: localization properties, energy spectra and enhancement of entanglement

description: We study the localization properties, energy spectra and coin-position entanglement of the aperiodic discrete-time quantum walks. The aperiodicity is described by spatially dependent quantum coins distributed on the lattice, whose distribution is neither periodic (Bloch-like) nor random (Anderson-like). Within transport properties we identified delocalized/localized quantum walks mediated by a proper adjusting of aperiodic parameter. Both scenarios are studied by exploring typical quantities (inverse participation ratio and survival probability), as well as the energy spectra of an associated effective Hamiltonian. By using the energy spectra analysis, we show that the early stage the inhomogeneity leads to vanishing gap between two main bands, which justifies the the delocalized character observed for $ν<0.5$. With increase of $ν$ arises gaps and flat-bands on the energy spectra, which corroborates the suppresion of transport detected for $ν>0.5$. For $ν$ high enough we observe an energy spectra which resembles that described by the 1d Anderson model. Within coin-position entanglement, we show many settings in which an enhancement in the ability to entangle is observed. This behavior brings new informations about the role played by aperiodicity on the coin-poisition entanglement for static inhomogeneous systems, reported before as almost always reducing the entanglement when comparing with the homogeneous case. We extend the analysis in order to show that systems with static inhomogeneity are able to exhibit asymptotic limit of entanglement.

description: An universal invariant for site and bond percolation thresholds (p_{cs} and p_{cb} respectively) is proposed. The invariant writes {p_{cs}}^{1/a_s}{p_{cb}}^{-1/a_b}=δ/d where a_s, a_b and δare positive constants,and d the space dimension. It is independent of the coordination number, thus exhibiting a topology invariance at any d.The formula is checked against a large class of percolation problems, including percolation in non-Bravais lattices and in aperiodic lattices as well as rigid percolation. The invariant is satisfied within a relative error of \pm 5% for all the twenty lattices of our sample at d=2, d=3, plus all hypercubes up to d=6.

description: Periodontal disease is associated with cardiovascular disease and is thought to accelerate systemic atherosclerosis. Here we examined the relationship between periodontitis and cardiovascular disease mortality in outpatients on hemodialysis using a retrospective analysis of 168 adult patients in New York City and North Carolina. During 18 months of follow-up, cardiovascular disease and all-cause mortality were determined from a centralized dialysis registry. One hundred patients had mild or no periodontal disease but the remaining 68 had moderate-to-severe disease defined as 2 or more teeth with at least 6 mm of inter-proximal attachment loss. At baseline, the proportion of males was significantly lower in the moderate-to-severe group. Compared with mild or no periodontal disease, moderate-to-severe disease was significantly associated with death from cardiovascular causes. Adjustment for age, gender, center and dialysis vintage, smoking status, and history of diabetes mellitus or hypertension did not diminish the strength of this association. Our findings suggest a need for larger studies to confirm this connection, along with intervention trials to determine if treating periodontitis reduces cardiovascular disease mortality in dialysis patients.
On the interpretation of spin-polarized electron energy loss spectra

description: We study the origin of the structure in the spin-polarized electron energy loss spectroscopy (SPEELS) spectra of ferromagnetic crystals. Our study is based on a 3d tight-binding Fe model, with constant onsite Coulomb repulsion U between electrons of opposite spin. We find it is not the total density of Stoner states as a function of energy loss which determines the response of the system in the Stoner region, as usually thought, but the densities of Stoner states for only a few interband transitions. Which transitions are important depends ultimately on how strongly umklapp processes couple the corresponding bands. This allows us to show, in particular, that the Stoner peak in SPEELS spectra does not necessarily indicate the value of the exchange splitting energy. Thus, the common assumption that this peak allows us to estimate the magnetic moment through its correlation with exchange splitting should be reconsidered, both in bulk and surface studies. Furthermore, we are able to show that the above mechanism is one of the main causes for the typical broadness of experimental spectra. Finally, our model predicts that optical spin waves should be excited in SPEELS experiments.

description: Bulk samples of carbon multilayer nanotubes with the structure of nested cones (fishbone structure) suitable for transport measurements, were prepared by compressing under high pressure (~25 kbar) a nanotube precursor synthesized through thermal decomposition of polyethylene catalyzed by nickel. The structure of the initial nanotube material was studied using high-resolution transmission electron microscopy. In the low-temperature range (4.2 - 100 K) the electric resistance of the samples changes according to the law ln ρ~ (T_0/T)^{1/3}, where T_0 ~ 7 K. The measured magnetoresistance is quadratic in the magnetic field and linear in the reciprocal temperature. The measurements have been interpreted in terms of two-dimensional variable-range hopping conductivity. It is suggested that the space between the inside and outside walls of nanotubes acts as a two-dimensional conducting medium. Estimates suggest a high value of the density of electron states at the Fermi level of about 5 10^{21} eV^{-1} cm^{-3}.

description: Graph based entropy, an index of the diversity of events in their distribution to parts of a co-occurrence graph, is proposed for detecting signs of structural changes in the data that are informative in explaining latent dynamics of consumers behavior. For obtaining graph-based entropy, connected subgraphs are first obtained from the graph of co-occurrences of items in the data. Then, the distribution of items occurring in events in the data to these sub-graphs is reflected on the value of graph-based entropy. For the data on the position of sale, a change in this value is regarded as a sign of the appearance, the separation, the disappearance, or the uniting of consumers interests. These phenomena are regarded as the signs of dynamic changes in consumers behavior that may be the effects of external events and information. Experiments show that graph-based entropy outperforms baseline methods that can be used for change detection, in explaining substantial changes and their signs in consumers preference of items in supermarket stores.

description: A study of some research suggested that the utilization of reusable materials has a constructive outcome through variousperspectives. This incorporates the upsides of enhancing the support of improvement work while lessening costs, givingresponses to pollution of the environment and decreasing the requirement for normal supplies. In this examination, an auditwas directed to find prevailing methods in the utilization of waste and reusable materials being developed work. Theoutcomes showed that a few associations didn't know about access, the nature of the usage of the materials, cost assets, orsome different favorable circumstances, including ecological advantages. In like manner, they were portrayed to give betterdocumentation to the Green Foundation, connecting industry examinations with a chart of what can be gotten to fromvarious materials being developed applications. Endeavors ought to be inventive in utilizing reusable materials andlessening their reliance on crude materials. Moreover, more data and high-grade documentation is required to enable wasteand reusable materials to be utilized for advancement work. In light of this audit of past research, this examination is asurvey of the utilization of waste and reused materials in the performance of the concrete structure.

description: To study the predictive value of biopsy lesions in IgA nephropathy in a range of patient ages we retrospectively analyzed the cohort that was used to derive a new classification system for IgA nephropathy. A total of 206 adults and 59 children with proteinuria over 0.5 g/24 h/ 1.73 m2and an eGFR of stage-3 or better were followed for a median of 69 months. At the time of biopsy, compared with adults children had a more frequent history of macroscopic hematuria, lower adjusted blood pressure, and higher eGFR but similar proteinuria. Although their outcome was similar to that of adults, children had received more immunosuppressants and achieved a lower follow-up proteinuria. Renal biopsies were scored for variables identified by an iterative process as reproducible and independent of other lesions. Compared with adults, children had significantly more mesangial and endocapillary hypercellularity, and less segmental glomerulosclerosis and tubulointerstitial damage, the four variables previously identified to predict outcome independent of clinical assessment. Despite these differences, our study found that the cross-sectional correlation between pathology and proteinuria was similar in adults and children. The predictive value of each specific lesion on the rate of decline of renal function or renal survival in IgA nephropathy was not different between children and adults.

description: Lightweight concrete (LWC) highly beneficial as a construction material, producing lower weight, improved durability, longer spans qualified, fewer piers, and continuation of bridge structures. LWC can be identified as one of the numerous compelling topics related of its benefits such as degraded in the size of concrete segments, reinforcement ratios, moldings and scaffolding, foundation expenses as well as the savings generated by the low cost of transport and constructing. Modifications in the dimensions of columns and beams size lead to a voluminous space, and reductions in self-weight can improve seismic resistance in building structures. Moreover, high-grade fire resistance, thermal insulation, sound absorption, frost resistance, and enhanced damping are other benefits of lightweight concrete.The main purpose of the present study is to investigate the lightweight concrete made from the lightweight material called (Perlite) as replacing part of coarse aggregate with ratios (0, 5, 10, 15, 20, 25 and 30%) and its effects on compressive strengths and density. Besides the effect of perlite powder, steel fiber effect with the content of (0, 1.0 and 2.0%) was studied. Twenty-one (cylinders and cubes) average specimens according to ASTM for determining the compressive strength and density tests are performed at age of 28 days. The results show good performance of concretes containing expanded perlite powder and increasing steel fiber content increasing the compressive strength.

description: Concrete represent the various well-known and extensively worked material to possess very high strength and adequate workability characteristics. This paper emphasizes on polymer steel fiber concrete. Five different concrete mixes were taken experimentally to study the effect of Styrene-Butadiene Rubber (SBR) latex with different dosages ratio of (0, 5, 10, 15 and 20%) and steel fiber with different ratios of (0, 1 and 2% by volume) on properties of different concrete mix with grade of concrete (30, 35, 47, 60 and 85). SBR latex polymer was adopted depending on weight of cement. Cubes and cylinders for the compressive strength test were prepared, and specimens were tested after 28 days of curing. This paper remarked that SBR latex has the contrary influence at the early age while at 28 days, the joining of SBR latex in concrete results in intensification of compressive strength. The results show that using SBR in dosages of (0, 5, 10, 15 and 20%) affects increasingly on compressive strength up to (15%) after that at 20% SBR effect decreasingly and the results is similar to ratio of 10%, that mean increase of SBR beyond 15% effect reversely on concrete because of its superplasticizer effects. The attachment of steel fibers to concrete will develop the compressive strength. The results show that for the five different concrete mixes, SBR effect decrease with the increase of concrete grade.

description: We consider quantum fluctuations of the charge on a small metallic grain caused by virtual electron tunneling to a nearby electrode. The average electron number and the effective charging energy are determined by means of perturbation theory in the tunneling Hamiltonian. In particular we discuss the dependence of charging effects on the number N of tunneling channels. Earlier results for N>>1 are found to be approached rather rapidly with increasing N.

Integral Ecology in Pope Francis' s Laudato Si': The Meaning of the Papal Category of Integral Ecology for the Haitian Context.
Creators: name: ST LOUIS, Jean Bertin
Publisher: name: Zenodo
Year: 2023

description: Haiti is facing an unprecedented ecological crisis today. This crisis appears at the level of climate change and by the loss of biodiversity among others. Many scientists and world religious leaders have started to respond more effectively to this pressing issue. Pope Francis raises his voice in an impactful way, inviting everyone to ecological conversion and to frankly dialogue about caring for our common home and protecting the planet. Beginning with the “The Legend of the Hummingbird” this paper frames the project into its eco-theological and ministerial context. This legend teaches in a poetic way the lesson of the consequences of remaining inactive in the face of the alarming situation happening to our common and shared home. We all are part of God’s creation, called to be in just and loving relationship while becoming more present to ourselves and the human and more-than-human neighbors with whom we are deeply connected.
