To create early warning capabilities for upcoming Space Weather disturbances, we have selected a dataset of 61 emerging active regions, which allows us to identify characteristic features in the evolution of acoustic power density to predict continuum intensity emergence. For our study, we have utilized Doppler shift and continuum intensity observations from the Helioseismic and Magnetic Imager (HMI) onboard the Solar Dynamics Observatory (SDO). The local tracking of 30.66 × 30.66-degree patches in the vicinity of active regions allowed us to trace the evolution of active regions starting from the pre-emergence state. We have developed a machine learning model to capture the acoustic power flux density variations associated with upcoming magnetic flux emergence. The trained Long Short-Term Memory (LSTM) model is able to predict 5 hours ahead whether, in a given area of the solar surface, continuum intensity values will decrease. The performed study allows us to investigate the potential of the machine learning approach to predict the emergence of active regions using acoustic power maps as input.
This article investigates the Ottoman Greek Orthodox internal exiles, focusing on the deportees’ experiences and the intricacies of their agency during the Great War (1914–18). It does so by examining deportees’ understudied ego-documents, taken either from the collections of the Centre for Asia Minor Studies in Athens or from family archives. Organized into labor-battalions or housed in open internment camps in town quarters, the inland exiles were deported to secure the rear front and homogenize the country, but their deportation was characterized by local influences and inconsistencies. Several of the Greek Orthodox exiles managed to survive and maintain their cultural ties by exploiting such inconsistencies, either by selling their skills or by resisting exile through solidarity, desertion, and resistance.
This paper uses a “dates as data” approach to understand how grave good use and cemetery space changed across the early medieval period in England. A series of composite kernel density estimations were created, based on a dataset of nearly 1100 graves with associated radiocarbon dates, from between the fourth and ninth centuries AD. This modeling revealed a previously unrecognized peak in grave furnishing around 600 AD, which coincides with a peak in isolated burials, and a low point for unfurnished graves and for small cemeteries. It argues that this peak is unrecognized as previous models of chronological change have focused only on graves containing chronologically distinctive artifacts and highlights the importance of radiocarbon dating as a way of avoiding this limitation.
Despite the growing body of literature on Chinese architecture, contemporary Chinese architects’ critical approaches to drawing have received little scrutiny. To address this research gap, this essay examines the 2012 Pritzker Architecture Prize laureate Wang Shu’s creative uses of modern parallel projection methods. The essay focuses on Wang’s specific drawing strategies that have allowed him to reconcile the disengaged mode of seeing that is engrained in parallel projection with the immersive spectatorship that traditional Chinese landscape painting epitomises.
First, through a literature review, this paper highlights Wang’s observations regarding the a-perspectival nature of Chinese landscape painting. Rather than being a perspectival window for the disengaged gaze, the landscape painting invites viewers to inhabit the pictorial space. Second, through comparative studies of selected cases, this essay investigates how Wang’s acknowledgement of the landscape painting’s a-perspectival traits has influenced his specific strategies when using parallel projection methods. The examined cases include Wang’s drawings for the Chen Mo Art Studio (Haiyan, 1998), the Tengtou Pavilion (Shanghai, 2009-10), and the Xiangshan Campus of the China Academy of Art Phases I and II (Hangzhou, 2002-08).
The essay concludes by highlighting significant changes in Wang’s later parallel projection drawings. Wang’s work has increasingly delineated architectural terrains as sensory topographies to foster viewers’ time-bound immersive spectatorships. Moreover, when serving his architectural ideas, Wang’s drawings have transcended the geometric representation of depth by implying spaces that exceed the limits of projection drawings. By examining his drawings, this essay sheds light on a salient yet underexamined aspect of Wang’s architectural undertakings. By investigating in-depth case studies of contemporary Chinese architectural drawings, this essay takes a crucial step towards a better understanding of this hitherto understudied domain.
Medical-legal partnerships connect legal advocates to healthcare providers and settings. Maintaining effectiveness of medical-legal partnerships and consistently identifying opportunities for innovation and adaptation takes intentionality and effort. In this paper, we discuss ways in which our use of data and quality improvement methods have facilitated advocacy at both patient (client) and population levels as we collectively pursue better, more equitable outcomes.
Fitness has taken center stage in debates concerning how best to identify evolutionary transitions in individuality (ETIs). An influential framework proposes that an ETI occurs only when fitness is exported from constituent particles to a collective. We reformulate the conceptual structure of this framework as involving three steps. The culminating step compares “counterfactual” fitnesses against a long-run measure of fitness. This comparison assumes that collective-level fitness mereologically supervenes on particle fitness. However, if this assumption is rigorously enforced, the proposed conditions for identifying ETIs prove to be too weak. We here suggest an alternative model of ETIs centered around traits.
