A brief description of the main methods for determining the fine structure constant is given. It is shown that the exact value of the fine structure constant is important for the new International System of Units (SI) and for fundamental metrology. Recent measurement results and theoretical calculations of the fine structure constant, as well as its possible space-time variations, are presented. The results of laboratory experiments on the search for long-term variations of the fine structure constant are described. The astrophysical and cosmological observational data on possible variability of the fine structure constant are displayed. The possibility of slightly lower values of the fine structure constant in the remote past as compared to its modern value, as well as the existence of unresolved problems related to possible space-time variations of the fine structure constant and the spread of the results of its precise laboratory measurements, are mentioned. Despite the absence of experimentally confirmed long-term variations of the fine structure constant at a high level of accuracy, possible practical applications of the results are noted, namely, the construction of an optical frequency standard with high stability and frequency reproduction accuracy based on the ytterbium-171 ion and a laser frequency synthesizer which may replace the caesium frequency standard.

AvatarStaging framework consists in directing avatars on a mixed theatrical stage, enabling a co-presence between the materiality of the physical actor and the virtuality of avatars controlled in real time by motion capture or specific animation players. It led to the implementation of the AKN_Regie authoring tool, programmed with the Blueprint visual language as a plugin for the Unreal Engine (UE) video game engine. The paper describes AKN_Regie main functionalities as a tool for non-programmer theatrical people. It gives insights of its implementation in the Blueprint visual language specific to UE. It details how the tool evolved along with its use in around ten theater productions. A circulation process between a nonprogramming point of view on AKN_Regie called Plugin Perspective and a programming acculturation to its development called Blueprint Perspective is discussed. Finally, a C++ Perspective is suggested to enhance the cultural appropriation of technological issues, bridging the gap between performing arts deeply involved in human materiality and avatars inviting to discover new worlds.

Data-to-text (D2T) generation aims to generate human-readable text from semi-structured data, such as tables and graphs. The recent success of D2T is largely attributed to advancements in LLMs. Despite the success of LLMs, no research has been conducted to illustrate the impact of model size on the performance of fine-tuned LLMs for D2T tasks. D2T model performance is typically assessed based on three key qualities: \textit{readability} (indicates fluency and coherence), \textit{informativeness} (measures content similarity), and \textit{faithfulness} (assesses consistency of factual information). It is currently uncertain whether increasing the size of LLMs effectively improves performance in D2T tasks across these three qualities. The objective of this study is to investigate the performance of fine-tuned LLMs in D2T tasks in terms of model size. Through extensive comparative analysis, we aim to elucidate both the advantages and limitations of scaling model sizes across five widely used D2T datasets (E2E, ViGGo, WikiTableText, DART, and WebNLG) and twelve state-of-the-art LLMs with varying sizes from five different LLM families (T5, BART, OPT, BLOOM, and Llama 2). To comprehensively cover all the three essential qualities of D2T models, we incorporate six widely recognized automatic metrics -- \textsc{BLEU}, \textsc{METEOR}, \textsc{BERTScore}, \textsc{MoverScore}, \textsc{Parent}, and \textsc{BARTScore}. We also provide an in-depth analysis of LLM performance concerning model size in the presence of source-reference divergence, a critical aspect of D2T tasks. Our investigation reveals that increasing LLM size enhances \textit{readability} and \textit{informativeness} in D2T tasks, but larger (in terms of size) LLMs may sacrifice \textit{faithfulness}. Moreover, small-sized LLMs show more resilience than larger ones when source-reference divergence is present.

This research deals with (sensory perception and reception of the Iraqi theatrical performance), considering perception is the process through which sensory information is recognized and interpreted, whether the stimuli are visual, auditory, or Tactile, olfactory, or gustatory, and given the importance of the topic, the researcher observed many philosophical opinions and theories. The religious and psychological aspects related to (sensory perception) were discussed to show the extent of the benefit of sensory perception of the Iraqi theatrical performance. The first chapter (the methodological framework) included the research problem, the limits of the research, and the most important terms used in the research. As for the second chapter (the theoretical framework), it included two sections, the first (the concept of sensory perception and its philosophy), and the second section on (the mechanism of perception), and the indicators for the theoretical framework. In the third chapter (research procedures), it was The researcher presented the play (Umm Al-Khosh) By its author and director (Mahmoud Abu Al-Abbas). The researcher chose the sample intentionally, adopting the descriptive analytical method. In the fourth chapter, the researcher also (discussed the results of the analysis) in accordance with the research objectives, as the researcher found that acting performance is supposed to be a means capable of awakening the imagination and feelings of the recipient, in order to feel Identify the characters and their situations so that he understands them in his mind, and the necessity of emphasizing the importance of vocal and performance technique. For the actor, with the aim of having a vocal and physical space that enables him to imitate an unlimited number of characters. Then the researcher confirmed the recommendations and proposals, and the researcher also arranged the sources and references in alphabetical order and without numbering.

In 2021-2023 In Yekaterinburg, 3 volumes of author's essays were published on the development of the cultural sphere of the capital of the Urals. The release of review texts was initiated by the Department of Culture of the Yekaterinburg Administration. On 864 pages, using archival materials, unique historical and contemporary photographs, the “spirit of the development of the arts” is presented - music, theater and cinema in Volume 1, sculpture, painting and architecture in Volume 2, literature, art education and the educational system in Volume 3. The chosen genre - essays - is original and productive. Texts are a form of summing up, recording successes in the development of the Yekaterinburg/Sverdlovsk sphere of culture. The tercentenary anniversary of Yekaterinburg (the city can be scientifically categorized as a regional or peripheral capital), which took place in 2023, is an occasion for reflection and further planning. Richly illustrated, gift-type books are deep and original from the point of view of analytics of the development of the cultural sphere. The authors were leading academic researchers and employees of the largest cultural institutions of Yekaterinburg - the Sverdlovsk Regional Museum of Local Lore, UrFU named after the first President of Russia B. N. Yeltsin, the Museum of the History of Yekaterinburg, the Sverdlovsk Music School named after P. I. Tchaikovsky. Using the general scientific critical method, methods of synthesis and analysis, the text of the review provides a brief overview of all three volumes of essays, characterizes the merits of the publication, and provides criticism.

Break-in' Point, a 2012 arts and science performance and community engagement research initiative, was presented in the spring and fall semesters at the University of Leeds in the United Kingdom at Stage@Leeds. The outcome of a collaboration between dance artist A3 and theoretical physicist A2, under the direction of performance researcher A1, Break-in' Point is based on a series of real-life encounters at intersections of arts and science - exploring force, risk, exposure and resilience. The Break-in' Point performance offered an interrogation of the critical point at which physical, mental, and/or emotional strength give way under stress - causing structural degeneration and the experience of what lies beyond. This article is an examination of the performance, reviewing and analysing it as an imagined somatic zone - embodied encounters that transcend temporal bound-ness, compelling and igniting new possibilities - that engaged spiritual and epistemological transformation of performers and audiences. The article addresses three main periods in the life of Break-in' Point: (1) the development period - script building and rehearsals, (2) the performance - live encounters between and among performers and audiences and (3) beyond the theatre - digital engagements in the classroom and pedagogy. The article contributes new concepts and new ways of thinking about science education, the role of digital technology in pedagogy, dance/theatre public engagement and community arts practices as practices of healing, health and resilience.

Optical cavities can support many transverse and longitudinal modes. A paraxial scalar theory predicts that the resonance frequencies of these modes cluster in different orders. A non-paraxial vector theory predicts that the frequency degeneracy within these clusters is lifted, such that each order acquires a spectral fine structure, comparable to the fine structure observed in atomic spectra. In this paper, we calculate this fine structure for microcavities and show how it originates from various non-paraxial effects and is co-determined by mirror aberrations. The presented theory, which applies perturbation theory to Maxwell's equations with boundary conditions, proves to be very powerful. It generalizes the effective 1-dimensional description of Fabry-Perot cavities to a 3-dimensional multi-transverse-mode description. It thereby provides new physical insights in several mode-shaping effects and a detailed prediction of the fine structure in Fabry-Perot spectra.

Sausage modes are one leading mechanism for interpreting short period quasi-periodic pulsations (QPPs) of solar flares. Forward modeling their radio emission is crucial for identifying sausage modes observationally and for understanding their connections with QPPs. Using the numerical output from three-dimensional magnetohydrodynamic (MHD) simulations, we forward model the gyrosynchrotron (GS) emission of flare loops modulated by sausage modes and examine the influence of loop fine structures. The temporal evolution of the emission intensity is analyzed for an oblique line of sight crossing the loop center. We find that the low- and high-frequency intensities oscillate in-phase at the period of sausage modes for models with or without fine structures. For low-frequency emissions where the optically thick regime arises, the modulation magnitude of the intensity is dramatically reduced by the fine structures at some viewing angles. On the contrary, for high-frequency emissions where the optically thin regime holds, the effect of fine structures or viewing angle is marginal. Our results show that the periodic intensity variations of sausage modes are not wiped out by the fine structures, and sausage modes remains a promising candidate mechanism for QPPs even when flare loops are fine-structured.

El laberinto ha sido tradicionalmente una de las estructuras físicas, psicológicas y simbólicas más relevantes y enigmáticas del mundo cultural occidental. Fértil como marco mítico para la literatura y el cine, apenas se ha explorado su impacto en el diseño de los videojuegos contemporáneos. Por ello, en este artículo exploramos cómo el laberinto, entendido como criterio de diseño físico y mítico, ha inspirado el videojuego tanto desde la perspectiva ludológica e interactiva como desde la visión simbólica de los mundos ludoficcionales. A partir de la herencia del juego analógico y los primeros videojuegos, realizamos una primera delimitación conceptual entre juego unicursal o labyrinth, multicursal o maze y rizomático. Acto seguido, aplicamos las dos primeras figuras al videojuego actual y analizamos las figuras centrales del mito – Teseo, el Minotauro y Ariadna – y su rol en la conformación de viejas y nuevas heroicidades, la concepción de la otredad y el mal y el juego como sendero vital interactivo.

Apresentam-se, neste ensaio, indagações e experimentações em forma de escritas e leituras com imagens de um coletivo de criação que se dedica há algum tempo a produzir academicamente com os campos da educação, da arte e da filosofia. Opera-se com os conceitos de percussão e de política de tambores, empreendidos por Basbaum (2017), com a noção de coletivo, abordada por Escóssia (2009) e Escóssia e Kastrup (2005), bem como com a noção de encontro, proposta por Deleuze e Parnet (1998). Do ponto de vista metodológico, aposta-se na noção de transversalidade (GUATTARI, 2004), agenciada por quatro pares de mãos, em revezamento. Buscam-se novas sonoridades, harmonias e melodias na produção científica, em meio a um território traçado entre leituras e escritas com imagens que, na composição deste ensaio, é atravessado também por sons e ruídos de um cotidiano acionado pelo confinamento físico provocado pela pandemia de Covid-19.

En el presente artículo aporto datos documentales inéditos del retablo mayor levantado, a partir de 1746, en la abadía del Sacro Monte de Granada (España), una institución contrarreformista fundada en 1610. Entre ellos destaca su autoría, al desconocido imaginero Domingo Cabrera, así como la evolución del proceso de su hechura y colocación, y su contextualización histórica. Ésta se enmarca dentro de los conocidos como “defensorios”, los cuales son una serie de textos que tenían como principal función restituir el prestigio del Sacro Monte, puesto en duda a partir de la condena como heréticos de los misteriosos libros plúmbeos que le dieron origen. Asimismo estaban estrechamente ligados a unos nuevos descubrimientos, que acontecieron en la Alcazaba Qadima, del barrio del Albaicín, a mediados del siglo XVIII, impulsados por Luis Francisco de Viana y Bustos, uno de los principales promotores del retablo.

Data movement is the dominating factor affecting performance and energy in modern computing systems. Consequently, many algorithms have been developed to minimize the number of I/O operations for common computing patterns. Matrix multiplication is no exception, and lower bounds have been proven and implemented both for shared and distributed memory systems. Reconfigurable hardware platforms are a lucrative target for I/O minimizing algorithms, as they offer full control of memory accesses to the programmer. While bounds developed in the context of fixed architectures still apply to these platforms, the spatially distributed nature of their computational and memory resources requires a decentralized approach to optimize algorithms for maximum hardware utilization. We present a model to optimize matrix multiplication for FPGA platforms, simultaneously targeting maximum performance and minimum off-chip data movement, within constraints set by the hardware. We map the model to a concrete architecture using a high-level synthesis tool, maintaining a high level of abstraction, allowing us to support arbitrary data types, and enables maintainability and portability across FPGA devices. Kernels generated from our architecture are shown to offer competitive performance in practice, scaling with both compute and memory resources. We offer our design as an open source project to encourage the open development of linear algebra and I/O minimizing algorithms on reconfigurable hardware platforms.

The fine structure constant $α$ and the ratio $h/m_{\mathrm{u}}$ between the Planck constant and the unified atomic mass are keystone constants for the determination of other fundamental physical constants, especially the ones involved in the framework of the future International System of units. This paper presents how these two constants, which can be deduced from one another, are measured. We will present in detail the measurement of $h/m_\mathrm{Rb}$ performed by atomic interferometry at the Laboratoire Kastler Brossel in Paris. This type of measurement also allows a test of the standard model to be carried out with unparalleled accuracy.

Abstract Liquid chromatography with UV–Vis and mass spectrometric detection (LC–DAD–MS) was applied to the identification of dyes and biological sources in samples from nineteenth to twentieth century ethnographic textiles from ASTRA National Museum Complex, Sibiu, Transylvania. The objects are part of the Romanian traditional costume and are among the first to be acquired for the museum collections, around 1905. Oral and written information mention such objects as homemade, with nearby materials, while literature mentions a significant number of local vegetal sources as being used for textile dyeing. The analytical protocol developed, based on the combined use of the UV–Vis and mass spectrometric detectors to associate the information and distinguish between major and minor dyes, facilitates a clear attribution of the dyes and biological source/sources used. Other techniques, such as X-ray spectroscopy and FTIR-ATR were successfully used to identify inorganic dyes, which may not be detected by LC–DAD–MS, as was the case of Prussian blue. A large number of biological sources was identified in the studied objects, both local and imported. The local sources identified include dyer’s broom (Genista tinctoria L.), sawwort (Serratula tinctoria L.), young fustic (Cotinus coggygria Scop.), Rhamnus berries, emodin based dyes (Rhamnus, Rheum, Rumex sp.) and woad (Isatis tinctoria L.), in perfect correlation with literature which states that local dyes were still in use in the period under discussion. Carminic acid containing insects (Dactylopius coccus Costa and Porphyrophora sp.) and redwood type Caesalpinia species should be considered a result of trade. Almost all the natural and synthetic dyes detected are frequently mentioned in a collection of recipes published by the Romanian Academy, in 1914. The richness in colours in belts, the use of insect dyes in shirts decoration and the large amount of cotton in shirts are illustrative for the owners’ status. The study provides a better valorisation of the Romanian traditional costume as witness of the rural society at the end of the nineteenth to beginning of the twentieth century and emphasizes the usefulness of chemistry in cultural heritage dedicated applications.

We show that every Sobolev function in $W^{1,p}_{\textrm{loc}}(U)$ on a $p$-quasiopen set $U \subset {\bf R}^n$ with a.e.-vanishing $p$-fine gradient is a.e.-constant if and only if $U$ is $p$-quasiconnected. To prove this we use the theory of Newtonian Sobolev spaces on metric measure spaces, and obtain the corresponding equivalence also for complete metric spaces equipped with a doubling measure supporting a $p$-Poincaré inequality. On unweighted ${\bf R}^n$, we also obtain the corresponding result for $p$-finely open sets in terms of $p$-fine connectedness, using a deep result by Latvala.

This study focuses on the works of three different groups of writers who dared to write in Auschwitz-Birkenau, where anyone caught with a piece of paper or a pencil stub was immediately sentenced to death. Accordingly, inmates produced virtually no written material (Shik, 2012), with certain rare exceptions: (1) The Sonderkommando, who documented everyday life at the camp, concealing their records in jars that they buried near the crematoria in the hope that someone would find them after the war, as indeed occurred. (2) Certain Polish political prisoners, who kept records in Auschwitz and managed to save their works. (3) Lili Kasticher, the only woman known to have written at Birkenau who did not belong to any organization; all her writings thus constituted her own private heroic initiative. She risked her life by stealing pieces of paper and pencil stubs to write poetry and encouraged her friends to do so, offering them a prize, a portion of her bread ration. Her writings were concealed on her person until her liberation in spring 1945.
