The warrior aristocracy of the Late Bronze Age Urnfield Period in County Somogy, south-western Transdanubia. The Lengyeltóti V hoard (County Somogy/Hungary)
Authors: Honti Szilvia , Jankovits Katalin 
Published: October 2022

Abstract
Discussed here is the presence of a warrior aristocracy in south-western Hungary, principally in County Somogy, during the early (and middle) Urnfield period (Br D–Ha A1-A2) based on the archaeological record. The period's offensive and protective weapons wielded by the warrior aristocracy during the Urnfield period (mid-thirteenth to ninth century BC) are exclusively known from hoards in this region; none have been recovered from burials. The Lengyeltóti V hoard contained a greave, a composite cuirass, a cheek-piece indicating the presence of a military aristocracy riding horses and wagons or chariots when going to battle and a realistic wheel model. The swords and spearheads were part of the period's offensive weaponry. The hoard's other articles represented the jewellery of the female aristocracy: a diadem, a torc and an ornamented disc pendant. The hoard contained over seven hundred items. In A. Mozsolics's view, the hoard could be assigned to the period lasting up to the close of the Hallstatt period (Ha A2). The rise of the warrior aristocracy began during the Br D, Br D/Ha A1 period, while its consolidation and heyday fell into the early Urnfield period (Ha A1). The aristocracy lived in hillforts – fortified settlements – which had a flourishing bronze industry. The number of settlements and burials declined drastically in the ensuing Ha B period in south-western Transdanubia.
Emerging mediaeval heritage: Environmental history research at Băgău (c. Alba, Romania) and the Bottomless Lake (Tăul fără fund)

Abstract
The investigation of a 8.1 m long peat sequence from Tăul fără
fund (“Bottomless Lake,” Transylvanian Basin, Northern Romania) offers a series representing wetland development since the Middle Holocene. The most striking feature of the sequence is a cca. 900 year-long hiatus caused by peatcutting in the 14th century AD. An artificial reservoir was constructed there in the Late Middle Ages by the excavation of the uppermost peat layer, afflicting a significant environmental impact on this remote location. One of the oldest documented Hungarian settlements from the time of the Hungarian Kingdom (11th century AD, presumably with previous history) in Transylvania was discovered in the vicinity of the former reservoir by an archaeological field survey. By harmonising historical data and the exact chronological sequence of the borehole, the creation of the reservoir was inserted into the local history of the developing mediaeval settlement network at the time when some of the early settlements had been abandoned and a permanent village was established, with a church and upscale landowners, in the area of present-day Băgău in the 13th to 14th century AD. Significant environmental impacts have emerged during this transitional period around the reservoir.
La nostalgia de las cosas, la arqueología de los sentimientos y el trampantojo foucaultiano
Authors: Bermejo Barrera José Carlos 
Published: October 2022

En la Historia y las Ciencias Sociales: Antropología, Sociología y Arqueología, los autores estructuralistas y postmodernos dejaron a un lado las ideas de hombre, sentimientos, valores y contingencia. Los nuevos conceptos de estructura, lenguaje y poder pasarían a ser las nuevas claves para explicar así el pasado y el mundo social. Sin embargo los gustos y sentimientos, que estos autores negaron de plano, estuvieron presentes en sus textos de un modo oblicuo.
En este artículo se expone ese doble vínculo textual a través del estudio de la historia de las cosas, la historia de los sentimientos y el análisis historiográfico de la obra maestra de Michel Foucault: Histoire de la folie á l´Âge classique.
John Cournos Among the Imagists: Prelude to Petrograd
Authors: Smith Marilyn Schwinn 
Published: October 2022

This article explores the overlooked contributions of John Cournos (1881–1966), a Russian-Jewish immigrant to the US, to the Anglo-American Imagist movement and his role as a bridge between English and Russian literary cultures. It examines his relationships with key figures such as Hilda Doolittle (writing under the name H.D.), Richard Aldington, and Ezra Pound, as well as his work translating Russian authors. The study delves into Cournos's time in Petrograd during the 1917 revolution, his poetry inspired by H.D., and his interactions with Russian poet Anna Akhmatova. Highlighting his literary and cultural exchanges, the article situates Cournos within the modernist movement, emphasizing his efforts to blend Russian and Western literary traditions amid geopolitical upheaval.

Published: October 2022

Hybride Anlagen als eine Mischform von monolithischen und modularen Anlagenteilen gewinnen in Zukunft immer mehr an Bedeutung, da rein modulare Anlagen nicht für jeden Anwendungsfall die gewünschten Vorteile erbringen. Die Automatisierung solcher Anlagen fehlt jedoch noch. In diesem Beitrag wird ein Ansatz für die konzeptionelle Modellierung von Automatisierungssystemen hybrider Anlagen auf Basis von Function Modules vorgestellt. Das vorgestellte Metamodell dient als Grundlage für die Synthese eines systematischen Workflows. Zudem werden ein erweiterter Workflow für das Design von Automatisierungslösungen hybrider Anlagen vorgestellt und Aspekte wie die Verschachtelung und Parametrierung von Function Modules behandelt sowie eine prototypische Implementierung gezeigt. Der hier vorgestellte Ansatz unterstützt die konzeptionelle Gestaltung der Automatisierung hybrider Anlagen und leitet Verfahrens- und Automatisierungsingenieure unter Nutzung einer systematischen Vorgehensweise.

Published: October 2022

ABSTRACT
Earthquakes usually cause severe injuries and loss of life, so researchers have developed various methods to predict them. However, the prediction accuracies of these methods are not satisfactory. Unlike most artificial intelligence earthquake prediction methods using earthquake catalogs or seismic wave data, this article proposes three earthquake prediction models based on deep convolutional neural network-based (EPM-DCNN) using 11 continuous earthquake precursory observation item data, including fluid, geomagnetic, and deformation disciplines. To enhance the accuracy of the location prediction of earthquakes, we propose a method to divide the research area into six prediction blocks based on the K-means++ clustering algorithm using the epicenter of historical earthquakes. Using earthquake precursory observation time-series data from 1 January 2015 to 31 December 2018, we construct approximately 34,000 samples by sliding a fixed window size. Each sample is subdivided into 13 categories by combining the magnitude label and prediction block label. The experimental results show that EPM–DCNN B proposed in this article has an accuracy of 99.0% and a recall of 99.8%, which demonstrates the effectiveness of EPM–DCNN for seismic prediction compared to several state-of-the-art baselines.

ABSTRACT
Earthquakes pose a major threat to the people of Haiti, as tragically shown by the catastrophic 2010 Mw 7.0 earthquake and more recently by the 2021 Mw 7.2 earthquake. Both events occurred within the transpressional Enriquillo–Plantain Garden fault zone (EPGFZ), which runs through the southern peninsula of Haiti and is a major source of seismic hazard for the region. Satellite-based Interferometric Synthetic Aperture Radar (InSAR) data are used to illuminate the ground deformation patterns associated with the 2021 event. The analysis of Sentinel-1 and Advanced Land Observation Satellite (ALOS)-2 InSAR data shows (1) the broad coseismic deformation field; (2) detailed secondary fault structures as far as 12 km from the main Enriquillo–Plantain Garden fault (EPGF), which are active during and after the earthquake; and (3) postseismic shallow slip, which migrates along an ∼40 km unruptured section of the EPGF for approximately two weeks following the earthquake. The involvement of secondary faults in this rupture requires adjustments to the representation of hazard that assumes a simple segmented strike-slip EPGF. This work presents the first successful use of phase gradient techniques to map postseismic deformation in a vegetated region, which opens the door to future studies of a larger number of events in a wider variety of climates.
Village Road Quality and Accessibility on Transforming Rural Development

Published: October 2022

Rural road infrastructure in Indonesia has increased significantly, especially during the last decade. This study presents an overview of how rural road quality and accessibility affected village economic transformation. It is the first empirical study in Indonesia addressing rural transformation. Village-level microdata, referring to the smallest administrative official, were utilized. Using a Random-Effects Panel Logit model, this study discovered that improving the type of road surface and accessibility for four-wheeled vehicles significantly increased the probability of village economic transformation. Different types of road infrastructure improvement affected the rural economic transformation both within and outside Java-Bali. Paved or concrete roads in Java-Bali had a higher marginal effect than on other islands, thereby increasing the likelihood of rural economic transformation. However, the road accessibility for four-wheeled vehicles in Java-Bali did not significantly affect the probability of rural economic transformation. Nevertheless, for villages on other islands, it did. Furthermore, the transformation significantly influenced other infrastructures, such as electricity coverage, market presence, information and communication technology (ICT), and flatland topography. Moreover, the road access to villages and the availability of water or irrigation significantly affected the probability of surviving in the agricultural sector. Following these findings, policymakers should prioritize villages’ infrastructure by considering different types of infrastructure provision across villages, referring to different infrastructure needs for Java-Bali and other islands.
