This paper aims to diversify the existing critical discourse by introducing new perspectives for the poetic, expressive, and ethical features of tactical media art that involves artificial intelligence (AI). It explores diverse approaches of AI artists and their effectiveness in critiquing the epistemic, phenomenological, and political aspects of AI science and technology. Focusing on the three representative thematic areas - sociocultural, existential, and political - it discusses the works that exemplify poetic complexity and manifest the ambiguities indicative of a broader milieu of contemporary art, culture, economy, and society. It shows that tactical AI art provides important insights into the AI-influenced world, with the potential to direct computational arts toward a socially responsible and epistemologically relevant expressive stratum. The closing sections summarize the major issues of tactical AI art and outline possible directions to tackle the challenges and advance the field.

The fine curve graph of a surface is the graph whose vertices are simple closed essential curves in the surface and whose edges connect disjoint curves. In this paper, we prove that the automorphism group of the fine curve graph of a surface is naturally isomorphic to the homeomorphism group of the surface for boundaryless planar surfaces with at least 7 punctures.

The fine curve graph was introduced to study homeomorphism group of surfaces. In this paper we study the topology of the Gromov boundary of this graph for closed surfaces with higher genus. We first prove a bounded geodesic image theorem for the fine curve graph, a consequence of which is the non-compactness of the Gromov boundary. Using this theorem, we are able to show that the Gromov boundary is linearly connected with respect to some visual metric.

We study the percolation velocity, $v_p,$ of a fine spherical particle in a sheared large-particle bed under gravity using discrete element method simulations for large-to-fine particle diameter ratios, $R=d/d_f,$ below and above the free-sifting threshold, $R_t\approx6.5.$ For $R<R_t,$ $v_p$ initially increases with increasing shear rate, $\dotγ,$ as shear-driven bed rearrangement reduces fine-particle trapping but then decreases toward zero due to fine-particle excitation for $\dotγ\sqrt{d/g}\gtrsim 0.1$. For $R>R_t$, $v_p$ is constant at low $\dotγ$ but decreases toward zero at higher shear rates due to fine-particle excitation.

The Harrison Horblit Collection at the Harvard University’s Houghton Library contains a remarkable daguerreotype plate by the Boston firm Southworth & Hawes. It reproduces an engraving after Raphael’s Transfiguration. Whereas reproductive printmaking normally seeks to produce multiples of a unique original, daguerreotype reproductions open a space of ambiguity between the categories of original and reproduction since daguerreotypes are unique objects. Much is lost in this translation, but what is gained? If reproduction of paintings normally renders the singular multiple, what happens when a painting is reproduced as a unique image? Why was this daguerreotype created? Southworth & Hawes specialized in portraits of celebrities and considered themselves artists. Why then did they make a daguerreotype of an engraving of a painting? And why this painting?Their image of an image of an image is at once simply duplicative and a meditation on photography itself – an expanded conception of photography that figures it as spiritual and conceptual practice, as is suggested in other conflations of image reproduction and transfiguration within Southworth & Hawes’ oeuvre as well. The logic of the Southworth & Hawes’ Transfiguration becomes less a conundrum when considered in relation to two of their other images, one of the branded hand of abolitionist Jonathan Walker, the other a self-portrait representing Southworth’s torso as a classical sculpture. Translation, transfiguration, body, soul and image are closely imbricated in all three of these daguerreotypes, each produced during the height of New England Transcendentalism. While Raphael’s Transfiguration epitomizes the intersection of the human and a divine being as Scriptural drama, The Branded Hand and Southworth as a Classical Bust allude to the spiritual realm through representation of the soul’s transcendence of the suffering body rather than direct reference to scripture. The Branded Hand detaches subject from the context of the body as a whole; Walker’s wound appears in the image as the silvery trace of the price paid for his abolitionist conviction. The portrait of Southworth separates an individual man’s identity from the more allegorical presence, while presenting suggestions of sorrow as emblems of spiritual elevation. But beyond this, the transmedial daguerreotype of the print of the Raphael announces itself as visual metonymy; the transfiguration of Christ in the painting also conveys the transfigurative power of the photographic medium itself.

The outdoor spaces of residential neighborhoods are an important part of residents' lives the outdoor spaces in the neighborhood are fundamental for the social life due to their capacity to serve as meeting spaces and interactions among the public, here comes this search, which is based on study of the role of highdensity –street level- on air temperature in outdoor space of neighborhoods. The methodology was based on three parts, initially, determine the sample which is three downtown residential neighbourhoods according to scientific criteria. secondly, conducting a field survey of climatic factors (air temperature - relative humidity - wind speed) thirdly, make a model to simulate the built environment by using the envi-met 4.4.6 program, according to the data of the survey, the results indicated that significant variations of value of DSR, MRT, AT variables among residential neighborhoods which points the effect of high-density street-level on air temperature in outdoor space.

Abstract Using past material and spiritual remains, cultural heritage examines communities’ identity formation across time. Cultural heritage requires public and private institutions to care about its restoration, maintenance, conservation, and promotion. Through a bibliometric perspective, this study has analyzed, quantified, and mapped the scientific production of the fourth industrial revolution applied to heritage studies from 2016 to 2021 in the Scopus and Web of Science databases. Biblioshiny software from RStudio was employed to categorize and evaluate the contribution of authors, countries, institutions, and journals. In addition, VOSviewer was used to visualize their collaboration networks. As a main result, we found that augmented reality and remote sensing represent the research hotspot concerning heritage studies. Those techniques have become common in archaeology, as well as museums, leading to an increase in their activity. Perhaps, more recent tools, such as machine learning and deep learning, will provide future pathways in cultural heritage from data collected in social networks. This bibliometric analysis, therefore, provides an updated perspective of the implementations of technologies from industry 4.0 in heritage science as a possible guideline for future worldwide research.

O artigo narra como se põe em marcha uma exposição, desde a seleção e solicitação em empréstimo das obras aos museus e aos colecionadores, atendendo aos requerimentos exigidos pelas instituições de empréstimo, até o transporte e suas condições e a instalação das obras na sala, o que requer uma montagem que deve atender a múltiplas, e algumas vezes contraditórias, necessidades.

We bottle it, we flush it, we drink it, we defecate in it, we swim in it. We pay to have it delivered and pay to have it taken away. We can’t live without it but can’t abide it when we’ve used it. We demand our potable water to be pathologically pure, yet routinely douse it in chemicals marked as poisons. Our current relationship with water is complex, irrational, historically specific, ideologically shaped; a complex hydro-social configuration that defies logic. As a result, the potable water resources which continue to underpin political economies relationally bind together public and private domains. Water use is personal and political; material, corporeal, cultural, social and spiritual interconnections which shape ourselves as humans and our relations with others and our environments. Understanding how these tropes of hydro-social relationships remake themselves reveals the power dynamics which shape the control of capital. This paper explores one element of this relationship through exploring the monetisation of the concept of waste prevention within current neoliberal practices of water provision. Within the English water sector water efficiency initiatives are heralded as an essential component of demand lead water security. Those water companies within water stressed regions are required to promote water efficiency technologies and practises; including consumer mindfulness of water use. However, water bills are mostly disaggregated from consumption; instead they are predicated on how much the water companies invest and whether this capital is raised through equity or debt over a five year cycle. Water users are therefore asked to prevent water wastage on environmental justice grounds, but with no tangible monetary savings for them and significant investment in infrastructure networks. The water companies benefit by less resource ‘output’ coupled with an enhanced ‘corporate social responsibility’ profile; especially vital as the domestic UK water market opens to competition. This paper explores how the financialisation of the water sector consequentially distorts human-nature relationships even further, with ‘water efficiency’ as a synecdoche for continued profiteering.

We investigate the spectrum and fine spectra of the finite Hilbert transform acting on rearrangement invariant spaces over $(-1,1)$ with non-trivial Boyd indices, thereby extending Widom's results for $L^p$ spaces. In the case when these indices coincide, a full description of the spectrum and fine spectra is given.

High-level synthesis (HLS) tools have brought FPGA development into the mainstream, by allowing programmers to design architectures using familiar languages such as C, C++, and OpenCL. While the move to these languages has brought significant benefits, many aspects of traditional software engineering are still unsupported, or not exploited by developers in practice. Furthermore, designing reconfigurable architectures requires support for hardware constructs, such as FIFOs and shift registers, that are not native to CPU-oriented languages. To address this gap, we have developed hlslib, a collection of software tools, plug-in hardware modules, and code samples, designed to enhance the productivity of HLS developers. The goal of hlslib is two-fold: first, create a community-driven arena of bleeding edge development, which can move quicker, and provides more powerful abstractions than what is provided by vendors; and second, collect a wide range of example codes, both minimal proofs of concept, and larger, real-world applications, that can be reused directly or inspire other work. hlslib is offered as an open source library, containing CMake files, C++ headers, convenience scripts, and examples codes, and is receptive to any contribution that can benefit HLS developers, through general functionality or examples.

Head pose estimation, which computes the intrinsic Euler angles (yaw, pitch, roll) from the human, is crucial for gaze estimation, face alignment, and 3D reconstruction. Traditional approaches heavily relies on the accuracy of facial landmarks. It limits their performances, especially when the visibility of the face is not in good condition. In this paper, to do the estimation without facial landmarks, we combine the coarse and fine regression output together for a deep network. Utilizing more quantization units for the angles, a fine classifier is trained with the help of other auxiliary coarse units. Integrating regression is adopted to get the final prediction. The proposed approach is evaluated on three challenging benchmarks. It achieves the state-of-the-art on AFLW2000, BIWI and performs favorably on AFLW. The code has been released on Github.

We investigate fine Selmer groups for elliptic curves and for Galois representations over a number field. More specifically, we discuss Conjecture A, which states that the fine Selmer group of an elliptic curve over the cyclotomic extension is a finitely generated $\mathbb{Z}_p$-module. The relationship between this conjecture and Iwasawa's classical $μ=0$ conjecture is clarified. We also present some partial results towards the question whether Conjecture A is invariant under isogenies.

Втрата людиною усталених ідентичностей та утворення їх нових, видозмінених варіантів, що апелюють до практик буденності в постмодерному суспільстві, сприяли тому, що гламур постав актуальним, виразним ідентифікатором й предметом досліджень. Ставлення до нього як до негативної тенденції в цілому, нажаль, домінує в наукових розвідках сучасників. Втім, на думку авторів публікації, саме явище гламур, гедоністичний спосіб життя, який його втілює в самих різноманітних аспектах і, безумовно, костюм як засіб візуальної репрезентації гламуру, мають не лише виразний емоційний, але й значний формотворчий потенціал не завжди негативного забарвлення. Особливо виразно це проявилося протягом ХХ століття, а на початку ХХІ – набуло системних проявів у конкретних моделях утілення й функціонування, які надають можливість не лише ідентифікувати, але й структурувати зв’язки між основними й опосередкованими характеристиками гламуру в контексті образів, тенденцій моди і дизайну.
