Abstract:

Acquisition of high-quality land seismic data requires (expensive) dense source and receiver geometries to avoid aliasing-related problems. Alternatively, acquisition using the concept of compressive sensing (CS) allows for similarly high-quality land seismic data using fewer measurements provided that the designed geometry and sparse recovery strategy are well matched. We have developed a complex wavelet-based sparsity-promoting wavefield reconstruction strategy to overcome challenges in land seismic data interpolation using the CS framework. Despite having lower angular sensitivity than curvelets, complex wavelets improve the reconstruction of sparsely acquired land data while being faster and requiring less storage. Unlike the Fourier transform, the complex wavelet transform localizes aliasing-related artifacts likely to be present in field data and yields reconstructions with fewer artifacts and higher signal-to-noise ratios. We determine that the data recovery success depends on the number and the geometry of the missing traces as revealed by analyzing reconstructions from multiple realizations of trace geometry and data decimation ratios. Using half the number of traces required by the regular sampling rules and thus reducing the acquisition costs, we find that data are appropriately reconstructed provided that there are no large gaps in the strategic places.

Abstract:

The spectrum of a discrete Fourier transform (DFT) is estimated by linear inversion, and used to produce desirable seismic traces with regular spatial sampling from an irregularly sampled data set. The essence of such a wavefield reconstruction method is to solve the DFT inverse problem with a particular constraint which imposes a sparseness criterion on the least‐squares solution. A working definition for the sparseness constraint is presented to improve the stability and efficiency. Then a sparseness measurement is used to measure the relative sparseness of the two DFT spectra obtained from inversion with or without sparseness constraint. It is a pragmatic indicator about the magnitude of sparseness needed for wavefield reconstruction. For seismic trace regularization, an antialiasing condition must be fulfilled for the regularizing trace interval, whereas optimal trace coordinates in the output can be obtained by minimizing the distances between the newly generated traces and the original traces in the input. Application to real seismic data reveals the effectiveness of the technique and the significance of the sparseness constraint in the least‐squares solution.

La ayuda humanitaria llevada a cabo después de los desastres no es un fenómeno reciente. Si bien las acciones de las grandes agencias humanitarias internacionales son conocidas, tales como las de la Cruz Roja Internacional, OXFAM y CARITAS Internacional entre otras, lo que es menos conocido, es el origen de las propuestas de los arquitectos sobre el tema del hábitat de emergencia y la reconstrucción. De hecho, si revisamos el tema con un corte histórico, observamos que las propuestas han estado bastante ligadas a corrientes y movimientos de la arquitectura sobre todo a partir del siglo XX. Este trabajo presenta los antecedentes de la participación de los arquitectos en el diseño de propuestas para emergencia y reconstrucción después de desastres y presenta algunas experiencias recientes en la región mesoamericana en Guatemala, El Salvador y México. Este trabajo muestra que las propuestas de reconstrucción de tipo participativo y utilizando procesos de ayuda mutua han sido mucho más exitosas que las experiencias masivas promovidas verticalmente por los gobiernos sin ninguna participación social.Abstract: The post-disaster humanitarian aid is not a new phenomenon. Although the actions of the great international humanitarian agencies are known, such as those of the International Red Cross, OXFAM and CARITAS International among others, which is less well-known, is the origin of the proposals of the architects on emergency shelter and reconstruction issues. In fact, if we review the subject from a historical cut, we may observe that the proposals have been linked to current movements of XXth century architecture mainly. This approach focuses on the antecedents of the architect’s participation in the design of proposals for post-disasters emergency and reconstruction and presents some recent experiences in the Mesoamerican region in Guatemala, El Salvador and Mexico. This paper suggests that the participating and mutual aid reconstruction processes has been much more successful than massive and vertical experiences promoted by governments without any social participation.Résumé : L’aide humanitaire fournie après les désastres n’est pas un phénomène récent.

Abstract:

Braking trace is the important basis to reconstruct the speed of the accident vehicle. There does not exist one-to-one relationship between the barking trace and the vehicle speed. It needs to have a further research on the factors influencing their corresponding relations, otherwise it may appear great errors to reproduce the vehicle speed with the braking trace. This paper analyzes the influence of people, cars, roads, environmental factors on the corresponding relationship between the initial braking velocity and braking traces, explores the use conditions and parameters selection of the reconstructed model in the standard GA/T643-2006, and the experiment is designed to research on the uncertainty of the reconstruction of the model. Besides, it has proposed the experimental reconstruction method.

Abstract:

AbstractThe theory of propagation in a direction almost parallel to the Earth’s magnetic field is reviewed, calculating the group refractive index of the ordinary ray in the presence of electron-neutral collisions. An electron density profile is estimated from the ordinary trace and is used to compute the z-ray trace. It is shown that this reconstruction can help to identify the rare cases of z-rays from among the numerous cases of duplicate ordinary traces, due to reflection from two different directions.

Abstract:

Abstract. We implement gravity wave (GW) phases into our convective plume and anelastic ray trace models. This allows us to successfully reconstruct the GW velocity, temperature, and density perturbation amplitudes and phases in the Mesosphere-Lower-Thermosphere (MLT) via ray tracing (in real space) those GWs that are excited from a deep convective plume. We find that the ray trace solutions agree very well with the exact, isothermal, zero-wind, Fourier-Laplace solutions in the Boussinesq limit. This comparison also allows us to determine the normalization factor which converts the GW spectral amplitudes to real-space amplitudes in the ray trace model. This normalization factor can then be used for ray tracing GWs through varying temperature and wind profiles. We show that by adding GW reflection off the Earth's surface, the resulting GW spectrum has more power at larger vertical and horizontal wavelengths. We determine the form of the momentum flux and velocity spectra which allows for easy calculation of GW amplitudes in the MLT and thermosphere. Finally, we find that the reconstructed (ray traced) solution for a deep, convective plume with a duration much shorter than the buoyancy period does not equal the Fourier-Laplace Boussinesq solution; this is likely due to errors in the Boussinesq dispersion relation for very high frequency GWs.

Abstract:

Quantum process tomography is the task of reconstructing unknown quantum channels from measured data. In this work, we introduce compressed sensing-based methods that facilitate the reconstruction of quantum channels of low Kraus rank. Our main contribution is the analysis of a natural measurement model for this task: We assume that data is obtained by sending pure states into the channel and measuring expectation values on the output. Neither ancillary systems nor coherent operations across multiple channel uses are required. Most previous results on compressed process reconstruction reduce the problem to quantum state tomography on the channel's Choi matrix. While this ansatz yields recovery guarantees from an essentially minimal number of measurements, physical implementations of such schemes would typically involve ancillary systems. A priori, it is unclear whether a measurement model tailored directly to quantum process tomography might require more measurements. We establish that this is not the case.Technically, we prove recovery guarantees for three different reconstruction algorithms. The reconstructions are based on a trace, diamond, and ℓ2-norm minimization, respectively. Our recovery guarantees are uniform in the sense that with one random choice of measurement settings all quantum channels can be recovered equally well. Moreover, stability against arbitrary measurement noise and robustness against violations of the low-rank assumption is guaranteed. Numerical studies demonstrate the feasibility of the approach.

Abstract:

How to reconstruct drawing and handwriting traces from surface electromyography (sEMG) signals accurately has attracted a number of researchers recently. An effective algorithm is crucial to reliable reconstruction. Previously, nonlinear regression methods have been utilized successfully to some extent. In the quest to improve the accuracy of transient myoelectric signal decoding, a novel hybrid algorithm KF-GEP fusing Gene Expression Programming (GEP) into Kalman Filter (KF) framework is proposed for sEMG-based drawing trace reconstruction. In this work, the KF-GEP was applied to reconstruct fourteen drawn shapes and ten numeric characters from sEMG signals across five participants. Then the reconstruction performance of KF-GEP, KF and GEP were compared. The experimental results show that the KF-GEP algorithm performs best because it combines the advantages of KF and GEP. The findings add to the literature on the muscle-computer interface and can be introduced to many practical fields.

Abstract:

Synchrotron radiation X-ray fluorescence spectroscopy (SRXRF) is a powerful technique for studying trace elements in biological samples and other materials in general. Its features including capability to perform measurements in air and water, noncontact and nondestructive assay are superior to other elemental analysis techniques. In this study, a technique for reconstructing elemental distribution mapping of trace elements from spectral data was developed. The reconstruction was made possible by using the measured fluorescent signals to obtain local differences in elemental concentrations. The proposed technique features interpolation and background subtraction using matrix transformations of the spectral data to produce an enhanced distribution images. It is achieved by employing polychromatic or monochromatic color assignments proportional to the fluorescence intensities for displaying single-element or multiple-element distributions respectively. Some typical applications (i.e., macrophage and tissue surrounding an implant) were presented and the samples were imaged using the proposed method. The distribution images of the trace elements of the selected samples were used in conjunction with other analytical techniques to draw relevant observations, which cannot be achieved using conventional techniques such as metallic uptake and corresponding cellular response. The elemental distribution images produced from this study were found to have better quality compared to images produced using other analytical techniques (e.g., SIMS, PIXE, XPS, etc).

Abstract:

Calcium imaging provides an indirect observation of the underlying neural dynamics and enables the functional analysis of neuronal populations. However, the recorded fluorescence traces are temporally smeared, thus making the reconstruction of exact spiking activity challenging. Most of the established methods to tackle this issue are limited in dealing with issues such as the variability in the kinetics of fluorescence transients, fast processing of long-term data, high firing rates, and measurement noise. We propose a novel, heuristic reconstruction method to overcome these limitations. By using both synthetic and experimental data, we demonstrate the four main features of this method: 1) it accurately reconstructs both isolated spikes and within-burst spikes, and the spike count per fluorescence transient, from a given noisy fluorescence trace; 2) it performs the reconstruction of a trace extracted from 1,000,000 frames in less than 2 s; 3) it adapts to transients with different rise and decay kinetics or amplitudes, both within and across single neurons; and 4) it has only one key parameter, which we will show can be set in a nearly automatic way to an approximately optimal value. Furthermore, we demonstrate the ability of the method to effectively correct for fast and rather complex, slowly varying drifts as frequently observed in in vivo data. NEW & NOTEWORTHY Reconstruction of spiking activities from calcium imaging data remains challenging. Most of the established reconstruction methods not only have limitations in adapting to systematic variations in the data and fast processing of large amounts of data, but their results also depend on the user’s experience. To overcome these limitations, we present a novel, heuristic model-free-type method that enables an ultra-fast, accurate, near-automatic reconstruction from data recorded under a wide range of experimental conditions.

Motivated by the newly proposal for gravity as the effect of the torsion scalar T and trace of the energy momentum tensor 𝒯, we investigate the cosmological reconstruction of different models of the Universe. Our aim here is to show that how this modified gravity model, f(T, 𝒯) is able to reproduce different epochs of the cosmological history. We explicitly show that f(T, 𝒯) can be reconstructed for ΛCDM as the most popular and consistent model. Also we study the mathematical reconstruction of f(T, 𝒯) for a flat cosmological background filled by two fluids mixture. Such model describes phantom–non-phantom era as well as the purely phantom cosmology. We extend our investigation to more cosmological models like perfect fluid, Chaplygin gas and massless scalar field. In each case we obtain some specific forms of f(T, 𝒯). These families of f(T, 𝒯) contain arbitrary function of torsion and trace of the energy momentum.

Abstract:

Reconstruction of past anthropogenic impact intensity in Lake Engure using sedimentary record analysis Environmental pollution with trace elements is considered as one of the most important environmental problems. Analysis of trace element accumulation in sedimentary phases of lakes may reflect the overall regional pollution level, and analysis of trace element accumulation patterns in sediment profiles can help to reconstruct the history of anthropogenic impact. The aim of this study was to analyse trace element concentrations in sediments of Lake Engure in Latvia and to determine factors influencing their availability. The metal concentrations in sediments of Lake Engure are at background levels, especially compared with metal concentrations in West European countries. However, the change in element concentration in sedimentary profiles provides information about trends of recent accumulation (within the last 100 years) and on the balance between natural and human-induced accumulation processes.

Abstract:

Literature of Second Life (SL) was retrieved, reviewed, and aggregated. Although it was found to provide sufficient information about SL’s social, technological, business model, and legal issues, and although SL received overall dense media coverage, the literature was found to be lacking when it comes to a thorough documentation of its economic development in 2003-2008. Using the retrieved literature, the attempt to reconstruct the development of the number of avatars, active users, prices and fees, and monetary development exposes the limits of reconstructing the economic development of a virtual world years after its popularity peak. This article serves as an argument and a reminder for a proper documentation of such developments. Future documentation of virtual worlds in academia should thoroughly track the economic development of next-generation virtual worlds. Otherwise, post-analysis, economic development reconstruction, and trace backs might prove difficult, costly, or infeasible.

Abstract:

Abstract The reconstruction of cosmic ray-induced air showers from measurements of radio waves constitutes a major challenge. In this work, we focus on recovering the full three-dimensional electromagnetic field from two recorded signal traces of an antenna station covering two horizontal polarization directions. The simulated field is folded by a direction and frequency-dependent characteristic antenna response pattern, resulting in voltage signal traces as a function of time. Both signal traces are contaminated by simulated background noise. We use conditional Invertible Neural Networks (cINNs) to learn posterior distributions, from which the most likely electromagnetic field given a measured signal trace can be inferred. To improve robustness, we extend the method with an autoencoder by reducing the parameter phase space and decoupling the cINN from specific data shapes. Thereby, each signal trace is condensed into a small number of abstract parameters in the latent space on which the cINN operates. The presented method shows promising results and can be transferred to other unfolding problems where the recovery of the pre-measurement state is of interest.

Abstract History as the past event, its tracking can be traced through the history trace. History trace is the fact and sign of history record which requires archives to disclosure. Archives as the history document is a silent witness which give evidence toward the success, failure, growth, and wealth of a nation. Archives, as past event record and a historical reconstruction, have an important role in building the nation character. The good nation character that contained in archives will strengthen the spirit of national anthem. Archive as the historical reconstruction can teach us a noble value, goodness, nasionalism, and teach us to follow the struggle value of the national heroes to free the nation from ivanders suppression. When archives that full of patriotism and nasionalism values are served to people, it will grow the collective consciousness of Indonesia that has ever had a strong character in struggling to achieve its independence. Therefore, correlation between archive and history in forming the national character relates to archives role as the historical values ( values of historical). Archive is an ambassador of its era which can give informations for the next era’s interest. Thus, history is actually not inanimatte object. It is a building “live” that has many wise messages to deliver. Keywords: archive, history, forming, character, nation.

Abstract:

Abstract Recent studies illustrate the correlation between the angular momenta of cosmic structures and their Lagrangian properties. However, only baryons are observable and it is unclear whether they reliably trace the cosmic angular momenta. We study the Lagrangian mass distribution, spin correlation, and predictability of dark matter, gas, and stellar components of galaxy–halo systems using IllustrisTNG, and show that the primordial segregations between components are typically small. Their protoshapes are also similar in terms of the statistics of moment of inertia tensors. Under the common gravitational potential they are expected to exert the same tidal torque and the strong spin correlations are not destroyed by the nonlinear evolution and complicated baryonic effects, as confirmed by the high-resolution hydrodynamic simulations. We further show that their late-time angular momenta traced by total gas, stars, or the central galaxies, can be reliably reconstructed by the initial perturbations. These results suggest that baryonic angular momenta can potentially be used in reconstructing the parameters and models related to the initial perturbations.

Abstract:

AbstractInfaunal communities in marine environments typically are tiered; that is, different taxa live at different depths within the sediment. Tiered suites of biogenic structures yield complex biogenic sedimentary fabrics (ichnofabrics), with the traces of deep-burrowing organisms overprinted on those of shallow-burrowing organisms. Careful analysis of crosscutting relationships of burrows in such composite ichnofabrics allows reconstruction of the tiered nature of fossil endobenthic communities. It is important to recognize that the best preserved and most prominently displayed trace fossils in most assemblages usually represent the deepest tier. Thus, they were farther removed from the sea floor and therefore less indicative of actual sea floor conditions than the more poorly preserved traces of the shallower tiers, on which the deeper traces are juxtaposed.

Abstract:

Entre los nahuas de Xolotla, en el municipio de Pahuatlán de Valle, ubicado en la Sierra Norte de Puebla, existe una antigua tradición oral que nos remite a un conjunto de seres sobrenaturales agrupados bajo el concepto de chichipahuatzitzi o ‘espíritus puros’. Estas entidades están encarnadas en distintos fenómenos naturales como los rayos (tlapetancame), las nubes (mexhuacante) y el agua (ahuacante); la Sirena (Zoliman) también está incluida en ellos. Otro personaje que forma parte del repertorio de la sobrenaturaleza es el Coixehuatl (el Dueño del Monte). A este conjunto igualmente debemos agregar a la tlahuepoche (la bruja), que es uno de los seres más característicos de la tradición oral indígena. A partir del mito y de lo que los xolotecos han escuchado de los más viejos, se puede conocer su apariencia física, el procedimiento para transformarse en guajolote, la manera en que ataca a sus víctimas y las formas de contrarrestar sus acciones nocivas; incluso, un mito referente a la tlahuepoche la ubica como la esposa de uno de los tlapetancame. Este artículo tiene dos objetivos: 1) esbozar una reconstrucción del antiguo panteón nahua xoloteco; y 2) interpretar los mitos de la tlahuepoche con base en el sistema indígena de eras, por medio de los cuales los contenidos culturales autóctonos han sido desplazados a un pasado remoto, que resultan inoperantes en el contexto actual.Abstract: Among the Nahuas of Xolotla, in the municipality of Pahuatlán de Valle, in the Sierra Norte de Puebla, there is an ancient oral tradition that refers us to an ensemble of supernatural beings grouped under the concept of chichipahuatzitzi, the ‘pure spirits’. These entities are embodied in different natural phenomena such as lightning bolts (tlapetancame), clouds (mexhuacante) and water (ahuacante). The Sirena (Zoliman) is included as well. Another character that is part of the repertoire of the supernature is the Coixehuatl (the Owner of the Mountain). This repertoire comprises also the tlahuepoche (the witch), who is one of the most characteristic beings of indigenous oral tradition. From the myth and what the Xolotecos have heard from the older ones, one can know the physical appearance of the tlahuepoche, the procedure to become a turkey, the way in which it attacks its victims and the ways to counteract its harmful actions; even, a myth referring to the tlahuepoche places her as the wife of one of the tlapetancame. This article has two objectives: In the first place, to outline a reconstruction of the ancient Nahua Xoloteco pantheon. Secondly, to interpret the myths of the tlahuepoche based on the indigenous system of eras, in so doing the native cultural contents have been displaced to a remote past, because they have become inoperative in the current context.Keywords: myth; supernatural entities; tlahuepoche; Nahuas; Pahuatlán.Résumé : Chez les Nahuas de Xolotla, dans la municipalité de Pahuatlán de Valle, dans la Sierra Nord de Puebla, il existe une ancienne tradition orale qui fait référence à un ensemble d’êtres surnaturels regroupés dans le concept de chichipahuatzitzi, les ‘esprits purs’. Ces entités sont incarnées dans plusieurs phénomènes naturels comme les foudres (tlapetancame), les nuages (mexhuacante) et l’eau (ahuacante) ; la Sirena (Zoliman) est aussi incluse dans ce groupe. Un autre personnage qui fait partie du répertoire du monde surnaturel est le Coixehuatl (le Maître de la Montagne). À cette liste il faut également ajouter la tlahuepoche (la sorcière), qui est l’un des êtres les plus caractéristiques de la tradition orale autochtone. A partir du mythe et de ce que les Nahuas de Xolotla ont écouté des personnes les plus âgées, on peut connaître l’apparence physique de la tlahuepoche, la procédure pour se transformer en dindon, la manière d’attaquer ses victimes et les façons de contre ses actions nocives; un mythe qui fait référence à la tlahuepoche la situe même comme l’épouse d’un des tlapetancame. Cet article a deux objectifs : en premier lieu esquisser une reconstruction de l’ancien panthéon Nahua de Xolotla ; et en deuxiòme lieu interpréter les mythes de la tlahuepoche sur la base du système indigène des époques, grâce aux quelles les contenus culturels autochtones ont été déplacés vers un passé distant, qui devient inopérant dans le contexte actuel.Mots-clés : mythe ; entités surnaturelles ; tlahuepoche ; Nahuas ; Pahuatlán.

Abstract:

Abstract. In order to assess the potential of the honeycomb oyster Pycnodonte vesicularis for the reconstruction of palaeoseasonality, several specimens recovered from late Maastrichtian strata in the Neuquén Basin (Argentina) were subject to a multi-proxy investigation, involving scanning techniques and trace element and isotopic analysis. Combined CT scanning and light microscopy reveals two calcite microstructures in P. vesicularis shells (vesicular and foliated calcite). Micro-XRF analysis and cathodoluminescence microscopy show that reducing pore fluids were able to migrate through the vesicular portions of the shells (aided by bore holes) and cause recrystallization of the vesicular calcite. This renders the vesicular portions not suitable for palaeoenvironmental reconstruction. In contrast, stable isotope and trace element compositions show that the original chemical composition of the foliated calcite is well-preserved and can be used for the reconstruction of palaeoenvironmental conditions. Stable oxygen and clumped isotope thermometry on carbonate from the dense hinge of the shell yield sea water temperatures of 11°C, while previous TEX86H palaeothermometry yielded much higher temperatures. The difference is ascribed to seasonal bias in the growth of P. vesicularis, causing warm seasons to be underrepresented from the record, while TEX86H palaeothermometry seems to be biased towards warmer surface water temperatures. The multi-proxy approach employed here enables us to differentiate between well-preserved and diagenetically altered portions of the shells and provides an improved methodology for reconstructing palaeoenvironmental conditions in deep time. While establishing a chronology for these shells was complicated by growth cessations and diagenesis, cyclicity in trace elements and stable isotopes allowed for a tentative interpretation of the seasonal cycle in late Maastrichtian palaeoenvironment of the Neuquén Basin. Attempts to independently verify the seasonality in sea water temperature by Mg ∕ Ca ratios of shell calcite are hampered by significant uncertainty due to the lack of proper transfer functions for pycnodontein oysters. Future studies of fossil ostreid bivalves should target dense, foliated calcite rather than sampling bulk or vesicular calcite. Successful application of clumped isotope thermometry on fossil bivalve calcite in this study indicates that temperature seasonality in fossil ostreid bivalves may be constrained by the sequential analysis of well-preserved foliated calcite samples using this method.

Full text

Abstract:

We apply the cross-coherence method to the seismic interferometry of traffic noise, which originates from roads and railways, to retrieve both body waves and surface-waves. Our preferred algorithm in the presence of highly variable and strong additive random noise uses cross-coherence, which uses normalization by the spectral amplitude of each of the traces, rather than crosscorrelation or deconvolution. This normalization suppresses the influence of additive noise and overcomes problems resulting from amplitude variations among input traces. By using only the phase information and ignoring amplitude information, the method effectively removes the source signature from the extracted response and yields a stable structural reconstruction even in the presence of strong noise. This algorithm is particularly effective where the relative amplitude among the original traces is highly variable from trace to trace. We use the extracted, reflected shear waves from the traffic noise data to construct a stacked and migrated image, and we use the extracted surface-waves (Love waves) to estimate the shear velocity as a function of depth. This profile agrees well with the interval velocity obtained from the normal moveout of the reflected shear waves constructed by seismic interferometry. These results are useful in a wide range of situations applicable to both geophysics and civil engineering.

Abstract:

The purpose of this paper is to explore the Hilbert space functional structure of the Helmholtz equation inverse source problem. An integral equation for the sources reconstruction based on the composition of the trace and Green's function operators is introduced and compared with the reciprocity source reconstruction methodologies. An equivalence theorem comparing the integral inverse source equation with the variational weak reciprocity gap functional equation is then demonstrated. Some examples on applications to the unitary disk are presented.

Abstract:

AbstractIn the wake of G. A. Cohen's masterful critique of Rawls's work, this paper discusses Rawlsian justice in general and the difference principle in particular. It argues that Rawlsian arguments for the difference principle present a puzzle and that to respond adequately to the puzzle we must engage in rational reconstruction. After explaining the puzzle and considering and rejecting a number of responses to it, the paper begins its reconstructive project. It presents the case for viewing the difference principle as a maximizing prioritarian principle of justice, one that that contains no trace of commitment to equality as a distributive norm. The paper concludes by bringing out some of the implications of viewing Rawlsian justice in this light.

Abstract:

Introduction. The authors study the cultural heritage site that somehow shapes the architectural appearance of the Musin-Pushkin estate, located at the intersection of Dobroslobodskaya and Spartakovskaya streets in Moscow (now this group of buildings accommodates the Moscow State University of Civil Engineering); it is the north wing of the architectural ensemble in the northern corner of the estate along the frontage line of Spartakovskaya street. This building is a cultural heritage site of federal significance; it’s interiors and facades have undergone numerous renovations and reorganizations. The main purpose of this work is to trace the history of this wing by analyzing it in the context of surrounding buildings, identify the initial appearance of this monument, track the periods of its construction, and, as a result, propose its graphic reconstruction, that will encompass not only its earliest period, but also the stage when its architectural form was changed to something new but not less interesting. Materials and methods. The method of comprehensive research was employed to study the monument. This method encompasses a search for and analysis of sources and literature, field studies, including probing, pit boring and taking measurements, as well as the chemical analysis of building and finishing materials. The comparative method was used to match this construction facility against other stylistically and typologically similar buildings. Results. As a result of the studies, the monument’s construction periodization was traced, the dates of its present-day appearance were identified, initial elements of the building were identified and studied, its further changes were traced to make a graphic reconstruction of the north wing since its very first days. Conclusions. The proposed reconstruction of the monument is a result of its comprehensive study needed to reconstruct the initial appearance of the building, including its missing parts. This project will allow tracing the history of the architectural appearance of a most interesting manor estate in Moscow.

Full text

Abstract:

Over time, Mark Blaug became increasingly sceptical of the merits of the approach to the history of economics that we find in his magnum opus, Economic theory in retrospect, first published in 1962, and increasingly leaned to favour 'historical' over 'rational' reconstructions. In this essay, I discuss Blaug's shifting historiographical position, and the changing terms of historiographical debate. I do so against the background of Blaug's personal life history and the increasingly beleaguered position the history of economic thought found itself in after the Second World War. I argue that Blaug never resolved the tensions between historical and rational reconstructions, partly because he never fleshed out a viable notion of historical reconstruction. I trace Blaug's difficulty in doing so to his firm conviction that the history of economics should speak to economists, a conviction clearly present in his 2001 essay: "No history of ideas, please, we're economists".

Abstract:

Abstract. The short-chain non-methane hydrocarbons (NMHC) are mostly emitted into the atmosphere by anthropogenic processes. Recent studies have pointed out a tight linkage between the atmospheric mole fractions of the NMHC ethane to the atmospheric growth rate of methane. Consequently, atmospheric NMHC are valuable indicators for tracking changes in anthropogenic emissions, photochemical ozone production, and greenhouse gases. This study investigates the 1950–2010 Northern Hemisphere atmospheric C2-C5 NMHC ethane, propane, i-butane, n-butane, i-pentane, and n-pentane. Atmospheric mole fractions of these trace gases were constructed from (a) air samples of these trace gases from air samples extracted from three firn boreholes in 2008 and 2009 at the North Greenland Eemian Ice Drilling (NEEM) site using state of the art models of trace gas transport in firn, and by (b) considering eight years of ambient NMHC monitoring data from five Arctic sites within the NOAA Global Monitoring Division (GMD) Cooperative Air Sampling Network. Results indicate that these NMHC increased by ~ 40–120% after 1950, peaked around 1980 (with the exception of ethane, which peaked approximately 10 years earlier), and have since dramatically decreased to be now back close to 1950 levels. The earlier peak time of ethane versus the C3-C5 NMHC suggests that different processes and emissions mitigation measures contributed to the decline in these NMHC. The 60 yr record also illustrates notable increases in the ratios of the isomeric iso-/n-butane and iso-/n-pentane ratios. Comparison of the reconstructed NMHC histories with 1950–2000 volatile organic compounds (VOC) emissions data and with other recently published ethane trend analyses from ambient air Pacific transect data showed (a) better agreement with North America and Western Europe emissions than with total Northern Hemisphere emissions data, and (b) better agreement with other Greenland firn air data NMHC history reconstructions than with the Pacific region trends. These analyses emphasize that for NMHC, having atmospheric lifetimes on the order of < 2 months, the Greenland firn air records are primarily a representation of Western Europe and North America emission histories.

Abstract:

Maintaining the homeostasis balance of trace elements is crucial for the health of organisms. Human health is threatened by diseases caused by a lack of trace elements. Saccharomyces cerevisiae has a wide and close relationship with human daily life and industrial applications. It can not only be used as fermentation products and single-cell proteins, but also as a trace elements supplement that is widely used in food, feed, and medicine. Trace-element-enriched yeast, viz., chromium-, iron-, zinc-, and selenium-enriched yeast, as an impactful microelements supplement, is more efficient, more environmentally friendly, and safer than its inorganic and organic counterparts. Over the last few decades, genetic engineering has been developing large-scaled genetic re-design and reconstruction in yeast. It is hoped that engineered yeast will include a higher concentration of trace elements. In this review, we compare the common supplement forms of several key trace elements. The mechanisms of detoxification and transport of trace elements in yeast are also reviewed thoroughly. Moreover, genes involved in the transport and detoxification of trace elements are summarized. A feasible way of metabolic engineering transformation of S. cerevisiae to produce trace-element-enriched yeast is examined. In addition, the economy, safety, and environmental protection of the engineered yeast are explored, and the future research direction of yeast enriched in trace elements is discussed.

Abstract:

It is known that after segmentation and morphological operations on scanned topographic maps, gaps occur in contour lines. It is also well known that filling these gaps and reconstruction of contour lines with high accuracy and completeness is not an easy problem. In this paper, a novel method is proposed dedicated in automatic or semiautomatic filling up caps and reconstructing broken contour lines in binary images. The key part of end points’ auto-matching and reconnecting is deeply discussed after introducing the procedure of reconstruction, in which some key algorithms and mechanisms are presented and realized, including multiple incremental backing trace to get weighted average direction angle of end points, the max constraint angle control mechanism based on the multiple gradient ranks, combination of weighted Euclidean distance and deviation angle to determine the optimum matching end point, bidirectional parabola control, etc. Lastly, experimental comparisons based on typically samples are complemented between proposed method and the other representative method, the results indicate that the former holds higher accuracy and completeness, better stability and applicability.
