Abstract:
In this paper I present a new dimension for philosophical and scientific analysis of artifacts as anthropogenic abiotic objects along the lines of the distinction between real and virtual. This distinction purports to replace the classical opposition material–ideal as a better way of defining what an artifact is and as one more compatible with the scientific description and explanation of artefacts. The virtual relativity of the virtual artifacts is their relatedness to local language forms as an adequate coordinate system. The real relativity of artifacts is their relatedness to local and global human life processes. The article follows empirical science as a technique of studying artifacts, and subscribes to the anthropological paradigm.

Abstract:
Because receiver wavefields reconstructed from observed data are not as stable as synthetic source wavefields, the source-propagation vector and the reflector normal have often been used to calculate angle-domain common-image gathers (ADCIGs) from reverse time migration. However, the existing data flows have three main limitations: (1) Calculating the propagation direction only at the wavefields with maximum amplitudes ignores multiarrivals; using the crosscorrelation imaging condition at each time step can include the multiarrivals but will result in backscattering artifacts. (2) Neither amplitude picking nor Poynting-vector calculations are accurate for overlapping wavefields. (3) Calculating the reflector normal in space is not accurate for a structurally complicated reflection image, and calculating it in the wavenumber ([Formula: see text]) domain may give Fourier truncation artifacts. We address these three limitations in an improved data flow with two steps: During imaging, we use a multidirectional Poynting vector (MPV) to calculate the propagation vectors of the source wavefield at each time step and output intermediate source-angle-domain CIGs (SACIGs). After imaging, we use an antitruncation-artifact Fourier transform (ATFT) to convert SACIGs to ADCIGs in the [Formula: see text]-domain. To achieve the new flow, another three innovative aspects are included. In the first step, we develop an angle-tapering scheme to remove the Fourier truncation artifacts during the wave decomposition (of MPV) while preserving the amplitudes, and we use a wavefield decomposition plus angle-filter imaging condition to remove the backscattering artifacts in the SACIGs. In the second step, we compare two algorithms to remove the Fourier truncation artifacts that are caused by the plane-wave assumption. One uses an antileakage FT (ALFT) in local windows; the other uses an antitruncation-artifact FT, which relaxes the plane-wave assumption and thus can be done for the global space. The second algorithm is preferred. Numerical tests indicate that this new flow (source-side MPV plus ATFT) gives high-quality ADCIGs.

Abstract:
Differential SAR Interferometry (DInSAR) has proven its unprecedented ability and merits of monitoring ground deformation on a large scale with centimeter to millimeter accuracy. However, atmospheric artifacts due to spatial and temporal variations of the atmospheric state often affect the reliability and accuracy of its results. The commonly-known Atmospheric Phase Screen (APS) appears in the interferograms as ghost fringes not related to either topography or deformation. Atmospheric artifact mitigation remains one of the biggest challenges to be addressed within the DInSAR community. State-of-the-art research works have revealed that atmospheric artifacts can be partially compensated with empirical models, point-wise GPS zenith path delay, and numerical weather prediction models. In this study, we implement an accurate and realistic computing strategy using atmospheric reanalysis ERA5 data to estimate atmospheric artifacts. With this approach, the Line-of-Sight (LOS) path along the satellite trajectory and the monitored points is considered, rather than estimating it from the zenith path delay. Compared with the zenith delay-based method, the key advantage is that it can avoid errors caused by any anisotropic atmospheric phenomena. The accurate method is validated with Sentinel-1 data in three different test sites: Tenerife island (Spain), Almería (Spain), and Crete island (Greece). The effectiveness and performance of the method to remove APS from interferograms is evaluated in the three test sites showing a great improvement with respect to the zenith-based approach.

Abstract:
Video Compression Artifact Reduction aims to reduce the artifacts caused by video compression algorithms and improve the quality of compressed video frames. The critical challenge in this task is to make use of the redundant high-quality information in compressed frames for compensation as much as possible. Two important possible compensations: Motion compensation and global context, are not comprehensively considered in previous works, leading to inferior results. The key idea of this paper is to fuse the motion compensation and global context together to gain more compensation information to improve the quality of compressed videos. Here, we propose a novel Spatio-Temporal Compensation Fusion (STCF) framework with the Parallel Swin-CNN Fusion (PSCF) block, which can simultaneously learn and merge the motion compensation and global context to reduce the video compression artifacts. Specifically, a temporal self-attention strategy based on shifted windows is developed to capture the global context in an efficient way, for which we use the Swin transformer layer in the PSCF block. Moreover, an additional Ada-CNN layer is applied in the PSCF block to extract the motion compensation. Experimental results demonstrate that our proposed STCF framework outperforms the state-of-the-art methods up to 0.23dB (27% improvement) on the MFQEv2 dataset.

Abstract. We use the Moderate Resolution Imaging Spectroradiometer (MODIS) satellite aerosol optical thickness (AOT) product to assess the impact of reduced swath width on global and regional AOT statistics and trends. Ten different sampling strategies are employed, in which the full MODIS dataset is sub-sampled with various narrow-swath (~400–800 km) and curtain-like (~10 km) along-track configurations. Although view-angle artifacts in the MODIS AOT retrieval confound direct comparisons between averages derived from different sub-samples, careful analysis shows that with many portions of the Earth essentially unobserved, the AOT statistics of these sub-samples exhibit significant regional and seasonal biases. These AOT spatial sampling artifacts comprise up to 60% of the full-swath AOT value under moderate aerosol loading, and can be as large as 0.1 in some regions under high aerosol loading. Compared to full-swath observations, narrower swaths exhibit a reduced ability to detect AOT trends with statistical significance, and for curtain-like sampling we do not find any statistically significant decadal-scale trends at all. An across-track sampling strategy obviates the MODIS view angle artifact, and its mean AOT converges to the full-swath mean values for sufficiently coarse spatial and temporal aggregation. Nevertheless, across-track sampling has significant seasonal-regional sampling artifacts, leading to biases comparable to the curtain-like along-track sampling, lacks sufficient coverage to assign statistical significance to aerosol trends, and is not achievable with an actual narrow-swath or curtain-like instrument. These results suggest that future aerosol satellite missions having significantly less than full-swath viewing are unlikely to sample the true AOT distribution well enough to determine decadal-scale trends or to obtain the statistics needed to reduce uncertainty in aerosol direct forcing of climate.

Abstract. We use the Moderate Resolution Imaging Spectroradiometer (MODIS) satellite aerosol optical thickness (AOT) product to assess the impact of reduced swath width on global and regional AOT statistics and trends. Along-track and across-track sampling strategies are employed, in which the full MODIS data set is sub-sampled with various narrow-swath (~ 400–800 km) and single pixel width (~ 10 km) configurations. Although view-angle artifacts in the MODIS AOT retrieval confound direct comparisons between averages derived from different sub-samples, careful analysis shows that with many portions of the Earth essentially unobserved, spatial sampling introduces uncertainty in the derived seasonal–regional mean AOT. These AOT spatial sampling artifacts comprise up to 60% of the full-swath AOT value under moderate aerosol loading, and can be as large as 0.1 in some regions under high aerosol loading. Compared to full-swath observations, narrower swath and single pixel width sampling exhibits a reduced ability to detect AOT trends with statistical significance. On the other hand, estimates of the global, annual mean AOT do not vary significantly from the full-swath values as spatial sampling is reduced. Aggregation of the MODIS data at coarse grid scales (10°) shows consistency in the aerosol trends across sampling strategies, with increased statistical confidence, but quantitative errors in the derived trends are found even for the full-swath data when compared to high spatial resolution (0.5°) aggregations. Using results of a model-derived aerosol reanalysis, we find consistency in our conclusions about a seasonal–regional spatial sampling artifact in AOT. Furthermore, the model shows that reduced spatial sampling can amount to uncertainty in computed shortwave top-of-atmosphere aerosol radiative forcing of 2–3 W m−2. These artifacts are lower bounds, as possibly other unconsidered sampling strategies would perform less well. These results suggest that future aerosol satellite missions having significantly less than full-swath viewing are unlikely to sample the true AOT distribution well enough to obtain the statistics needed to reduce uncertainty in aerosol direct forcing of climate.

Abstract:
Software refactoring is a software maintenance action to improve the software internal quality without changing its external behavior. During the maintenance process, structural refactoring is performed by remodularizing the source code. Software clustering is a modularization technique to remodularize artifacts of source code aiming to improve readability and reusability. Due to the NP hardness of the clustering problem, evolutionary approaches such as the genetic algorithm have been used to solve this problem. In the structural refactoring literature, there exists no search-based algorithm that employs a hierarchical approach for modularization. Utilizing global and local search strategies, in this paper, a new search-based top-down hierarchical clustering approach, named TDHC, is proposed that can be used to modularize the system. The output of the algorithm is a tree in which each node is an artifact composed of all artifacts in its subtrees and is a candidate to be a software module (i.e., cluster). This tree helps a software maintainer to have better vision on source code structure to decide appropriate composition points of artifacts aiming to create modules (i.e., files, packages, and components). Experimental results on seven folders of Mozilla Firefox with different functionalities and five other software systems show that the TDHC produces modularization closer to the human expert’s decomposition (i.e., directory structure) than the other existing algorithms. The proposed algorithm is expected to help a software maintainer for better remodularization of a source code.

Abstract:
Making prototypes of fictitious artifacts has long been applied in corporations as a design-led way to envisioning the future. These techniques make use of design to explore speculative futures translating abstract questions into concrete objects and bringing the human dimension and experience into futures techniques. The design-led strategic foresight techniques follow making activities – including visual synthesis, prototyping and storytelling – and result in experimental and experiential artifacts offering concrete, hands-on and specific images of the futures. An example of these techniques is the making and sharing of concept cars, a long-standing practice in the automotive industry. These artifacts facilitate the sharing of future visions, which embody future ideas, to diverse people. Whereas corporations use these design-led strategic foresight techniques as a driver for innovation, small and medium-sized enterprises, which are the backbone of society and the global economy, have been deprived of these kinds of explorations due to their being resource intensive. To help these enterprises, we developed DIVE (design, innovation, vision and exploration) based on design-led strategic foresight techniques developed by corporations but adapted to the scale and needs of these small players. DIVE helps external designers and company representatives in making and sharing artifacts to envision the future of their company. The technique follows an analogy that invites participants to make a hole in the world as it is and descend underwater to the speculative futures and then come back to the reality. Along with this plunge into fiction, participants identify trends, create ideas about the future, and make a prototype of an artifact that is subsequently used to motivate people to talk about the company’s future and present. This artifact, the vision concept, includes ideas about the future product or service, the context and the business itself. This paper aims to evaluate DIVE as a design-led strategic foresight technique and focuses on the benefits and limitations of its application. It includes two cases that explored the future of the shopping experience for the company Solutions Group. It is a Colombian medium-sized enterprise that develops and produces point-of-purchase materials for consumer goods corporations such as Procter & Gamble. In both cases, the participants employed DIVE activities to make and share a vision concept. At the end of the cases, the DIVE outcomes were validated by three external innovation experts. DIVE proved its efficacy in supporting designers in setting future visions, prototyping vision concepts and stories and making recommendations for different time frames, and participants also learned about the strategic value of design.

Abstract:
Ancient glass artifacts were susceptible to weathering from the environment, causing changes in their chemical composition, which pose significant obstacles to the identification of glass products. Analyzing the chemical composition of ancient glass has been beneficial for evaluating their weathering status and proposing measures to reduce glass weathering. The objective of this study was to explore the optimal machine learning algorithm for glass type classification based on chemical composition. A set of glass artifact data including color, emblazonry, weathering, and chemical composition was employed and various methods including logistic regression and machine learning techniques were used. The results indicated that a significant correlation (p < 0.05) could only observed between surface weathering and the glass types (high-potassium and lead–barium). Based on the random forest and logistic regression models, the primary chemical components that signify glass types and weathering status were determined using PbO, K2O, BaO, SiO2, Al2O3, and P2O5. The random forest model presented a superior ability to identify glass types and weathering status, with a global accuracy of 96.3%. This study demonstrates the great potential of machine learning for glass chemical component estimation and glass type and weathering status identification, providing technical guidance for the appraisal of ancient glass artifacts.

Abstract:
abstract: Eat Your Heart Out is a visually rich qualitative ethnic food research that examines consumption, production, and distribution practices transnationally. Through the example of Mumbai’s street foods, the study aims to discover how design participates in fashioning the street food experiences locally and globally. Food is an important cultural artifact in the world. However, past research in design suggests that the discipline has mainly focused on food as a catalyst for creativity and imagination or as a tool to examine materialistic, economical, sensorial, and emotional connections. Studying the user-focused involvement in the creation of food artifacts and focusing on cultural, global, and historical aspects of that participation are important to address the gaps in the knowledge required to solve increasingly “wicked problems” (Buchanan, 1992; Rittel, 1971). To achieve this goal, Eat Your Heart Out implemented a comparative practice-based study of the Indian street foods in Mumbai and Phoenix to examine consumption, production, and distribution practices at both places. The methodological design was highly multi-disciplinary in nature and included rapid ethnographic assessment, interviews, visual research, and a generative method of co-creation. The study revealed that street foods as cultural artifacts were deeply rooted in specific traditional values specific to the context, which significantly influenced personal and communal consumption, production, and distribution practices of Indian street foods in Mumbai and Phoenix. The values of standardization, formality, and higher food regulation practices limited the diversity and radically transformed the central values of Mumbai’s street foods when the foods re-territorialized in Phoenix. This resulted in lowering the consumption. Eat Your Heart Out presents cultural and practical insights into the interactions between contexts, artifacts, practices, and participants. Eat Your Heart Out recommends new frameworks of correlation for various consumption and production practices and suggests how street food artifacts alter when they move across cultures. Such knowledge can be valuable for similar ethnic food culture studies and the development of innovative research tools incorporating transnational and multidisciplinary methods in the future. On a broader scope, Eat Your Heart Out provides a unique opportunity to study a culture that has not been examined by scholars much in the past. It also focuses on gaining knowledge about ethnic culinary practices of Indian immigrants in the United States and encouraging enhanced cross-cultural acceptance.

Abstract:
The Pictorial Art of El Greco: Transmaterialities, Temporalities, and Media investigates El Greco’s pictorial art as foundational to the globalising trends manifested in the visual culture of early modernity. It also exposes the figurative, semantic, and allegorical senses that El Greco created to challenge an Italian Renaissance-centered discourse. Even though he was guided by the unprecedented burgeoning of devotional art in the post-Tridentine decades and by the expressive possibilities of earlier religious artifacts, especially those inherited from the apostolic past, the author demonstrates that El Greco forged his own independent trajectory. While his paintings have been studied in relation to the Italian and Spanish school traditions, his pictorial art in a global Mediterranean context continues to receive scant attention. Taking a global perspective as its focus, the book sheds new light on El Greco’s highly original contribution to early Mediterranean and multi-institutional configurations of the Christian faith in Byzantium, Venice, Rome, Toledo, and Madrid.

Industrialization refers to an economic transformation that is recent and different in scale and scope from the mere making of artifacts and has involved the rapid rise in the significance of manufacturing in relation to all other forms of production and work undertaken within national economies. This article discusses the many facets of industrialization: industrialization as a historical process; the present tendencies and future trends in global diffusion; inter-sectoral connections; international relations and the global context; and industrialization on a global scale over the very long run. In the twenty-first century success seems to require new and different political and social capabilities that are already shifting the concentrations of industrial activity away from Europe and North America and back to Asia.

Abstract:
This chapter shows that three of the central debates within global normative theory are afflicted by the three pathologies associated with the dominant approach. Constructivist methods for identifying principles of justice are both blatantly undemocratic and severely distortional; debates about the scope of justice are depoliticizing, question begging, and philosophically irresolvable; claims about how the global order affects the poor depoliticize and distort power relations in the global economy and ignore the ideological context in which the claims themselves operate. The argument is not that IMT gives problematic answers to these questions but rather that the questions themselves are unhelpful and unnecessary, artifacts of the approach. In making these arguments, the chapter continues the work of defamiliarization begun in the previous chapter.

Abstract:
Abstract It is frequently suggested that designing artifacts requires a deep understanding of context. We analyzed 186 papers from three specific literature searches involving a design process for global development applications. Each paper was reviewed and coded for (1) whether or not the study teams performed some level of contextual investigation, (2) the methods and/or approaches for understanding the artifact’s context, and (3) use of open-ended analysis or framework-based analysis for qualitative contextual investigation. In total, 159 papers (85%) described some level of contextual investigation with 46 of these describing performance-focused field tests in the artifact’s context of use and 113 papers using qualitative methods for contextual investigation. 18 papers used a framework, such as a cited questionnaire, for analyzing their contextual data, overwhelmingly during needs assessment and validation stages of design. We find that study teams of every paper motivated their design with contextual information, but there was great diversity in how context was investigated, analyzed, and described. Few linked their design decisions to specific contextual factors. We recommend that researchers include detailed description of methods and contextual factors considered during their design process to improve the transferability and repeatability of design approaches.

Abstract:
In recent years, many convolutional neural network-based models are designed for JPEG artifacts reduction, and have achieved notable progress. However, few methods are suitable for extreme low-bitrate image compression artifacts reduction. The main challenge is that the highly compressed image loses too much information, resulting in reconstructing high-quality image difficultly. To address this issue, we propose a multimodal fusion learning method for text-guided JPEG artifacts reduction, in which the corresponding text description not only provides the potential prior information of the highly compressed image, but also serves as supplementary information to assist in image deblocking. We fuse image features and text semantic features from the global and local perspectives respectively, and design a contrastive loss built upon contrastive learning to produce visually pleasing results. Extensive experiments, including a user study, prove that our method can obtain better deblocking results compared to the state-of-the-art methods.

Abstract:
Objectives. The overall goal of the proposed research was to develop a mechanistic understanding of tospovirus evolution, diversity and vector specificity that could be applied to development of novel methods for limiting virus establishment and spread. Our specific objectives were: 1) To characterize newly intercepted tospoviruses in onion, Hippeastrum and other bulb crops and compare them with the known tomato spotted wilt virus (TSWV) and its isolates; 2) To characterize intra- and interspecific variation in the virus transmission by thrips of the new and distinct tospoviruses. and, 3) To determine the basis of vector specificity using biological, cellular and molecular approaches. Background. New tospoviruses infecting bulb crops were detected in Israel and the US in the mid-90s. Their plant host ranges and relationships with thrips vectors showed they differed from the type member of the Tospovirus genus, tomato spotted wilt virus (TSWV). Outbreaks of these new viruses caused serious crop losses in both countries, and in agricultural and ornamental crops elsewhere. In the realm of plant infecting viruses, the tospoviruses (genus: Tospovirus , family: Bunyaviridae ) are among the most aggressive emerging viruses. Tospoviruses are transmitted by several species of thrips in a persistent, propagative fashion and the relationships between the viruses and their thrips vectors are often specific. With the emergence of new tospoviruses, new thrips vector/tospovirus relationships have also arisen and vector specificities have changed. There is known specificity between thrips vector species and particular tospoviruses, although the cellular and molecular bases for this specificity have been elusive. Major conclusions, solutions and achievements. We demonstrated that a new tospovirus, iris yellow spot virus (IYSV) caused "straw bleaching" in onion (Allium cepa) and lisianthus necrosis in lisianthus (Eustoma russellianum). Characterization of virus isolates revealed genetic diversity among US, Brazilian, Dutch and Israeli isolates. IYSV was not seed transmitted, and in Israel, was not located in bulbs of infected plants. In the US, infected plants were generated from infected bulbs. The relationship between IYSV and Thrips tabaci was shown to be specific. Frankliniella occidentalis, the primary vector of many other tospoviruses, did not transmit IYSV isolates in Israel or the US. Furthermore, 1': tabaci populations varied in their transmission ability. Transmission was correlated to IYSV presence in thrips salivary glands. In Israel, surveys in onion fields revealed that the onion thrips, Thrips tabaci Lindeman was the predominant species and that its incidence was strongly related to that of IYSV infection. In contrast, in the U.S., T. tabaci and F. occidentalis were present in high numbers during the times sampled. In Israel, insecticides reduced onion thrips population and caused a significant yield increase. In the US, a genetic marker system that differentiates non-thrips transmissible isolates from thrips transmissible isolate demonstrated the importance of the M RNA to thrips transmission of tospoviruses. In addition, a symbiotic Erwinia was discovered in thrips and was shown to cause significant artifacts in certain types of virus binding experiments. Implications, scientific and agricultural. Rapid emergence of distinct tospoviruses and new vector relationships is profoundly important to global agriculture. We advanced the understanding of IYSV in bulb crops and its relationships with thrips vector species. The knowledge gained provided growers with new strategies for control and new tools for studying the importance of particular viral proteins in thrips specificity and transmission efficiency.
